I say life has many turns. Today I run a publishing firm and am glad
I took print shop and Journalism in high school although at the time I
had no idea I would ever apply those skills. When I decided to go for a
Doctorate in psychology, I had to learn statistics, and applied algebra
at the time I learned it I thought was useless. When I built a ranch in
Mexico, I applied Geometry. I had enjoyed geometry very much in high school,
but did not foresee it would help me out when I was in rural Mexico, trying
to calculate the height of supporting beams on a slope, where no one could
physically measure. With the change rate so fast, we only dimly imagine
the kinds of jobs we will have, and some of our "academic" learning can
actually be quite practical.

Ted, when I taught eighth grade English, I tried many answers to that or similar questions. I found that kids would not accept answers as logical yours, so I responded "OK, so what are you going to study the rest of this hour?" A shrug of shoulders and back to Macbeth.
It works with a lot of questions. It worked with my three year grandson
today. "Why do I have to eat peas?" "Well, if you don't eat the peas what
are you going to eat?" After a long staring session with the peas that
he could stare a way, he ate them. His mother was going into the kitchen,
heard the question but not the answer. She returned at about the time he
was finishing his peas and asked me "How did you do that?" "Just a little

Dr. Keith Devlin, NPR's "Math Guy" and author of The Math Gene: How
Mathematical
Thinking Evolved and Why Numbers Are Like Gossip, recently gave an
entertaining and
informative talk on the Northern Kentucky University campus about math
and the skills necessary
to do math, which is also the subject of his book.
Devlin's explanation for why learning math is so hard is illustrated
by a comparison: Math is like a
TV soap opera. The relationships in the soap opera world are very complex
 wife / daughter /
husband / lover / exlover # 1 / exlover #2 / exlover #1 who is also
stepfather #2 / etc.
Understanding a soap opera may seem easy because we are very familiar
with the terms,
concepts, and relationships that are needed to understand what goes
on in the soap opera world.
The relationships in mathematics are no more complex than the relationships
in a soap opera, but
most of us are not so familiar with the terms, concepts, and relationships
in the math world. If you
didn't know the term lover, the term daughter, the concept of incest,
then the equation lover +
daughter = incest would be very perplexing. We can focus on the drama
because the terms,
concepts, relationships are relatively wellknown. In math, most of
us have not been and are not
immersed in the terms, concepts, and relationships. We need to find
a way to teach math so
students can focus on the drama of math.
Why do students need to learn mathematics? Well, Dr. Thomas L. Magliozzi
(aka Click, or is it
Clack?, on NPR's "Car Talk") once ranted rather seriously that math
courses are designed only to
prepare students for the next math course, which most students never
take. He also debunked the
idea that "math is good for the mind"  is there an instructor of
a college course that will admit that
his or her course is NOT good for the mind? Perhaps we ought to require
more physical
education, since there is at least some hard evidence that physical
activity improves mental ability.
Why do students need to learn math? Because educated people should be
numerate as well as
literate. But to my mind, being numerate does not mean Algebra I to
prepare students for Algebra
II to prepare students for College Algebra to prepare students for
Calculus I or whatever next
level math course most students have no intention of taking.

Here's one possible response. Tell him/her:
I'll make a deal with you. You tell me exactly what career you're going
to be
doing for the REST OF YOUR LIFE, and I'll teach you ONLY what you need
to
know for that specific career... nothing more, nothing less. (We could
probably compress your time in school by several years, too.) But remember,
if you ever decide to CHANGE careers, tough! You won't have ANY
skills/abilities for another job. And you won't know how to LEARN them,
either!
(It's estimated that the average worker changes jobs 10 times and careers
three times in a working lifetime.)

Ahhh  where possible, a metaphor to demonstrate the need.
I recently worked with a faculty member who was trying to teach
pharmacy assistant students the importance of learning math. She
had tried bags of candy to represent percentages, and all manner
of examples, but could not get them to understand in their
calculations why it mattered where they put the decimal point  "I
got the numbers right, so I should only get half a mark taken off.."
etc.
The solution (pun intended) we brainstormed was this: The
following class she went in and set up two sets of medicine cups of
liquid (it was juice) at the front of the room. She told the students

I want you to come and select your medication  the set on the
right was prepared by a pharmacy assistant who calculated
correctly, and the second set are correct except that the assistnat
got the decimal point in the wrong place. They are ten times as
strong as they should be, and are toxic. Please choose your
medicine. Surprise, noone wanted to choose from that set.
She could have explained all that, but the graphic illustration sunk
in, and while her students didn't become overnight math geniuses,
they never again raised the question of decimal placement.

Just to follow up that 'use' of math. When a couple of Math Educators
(Celia Hoyes and Richard Noss)
followed around nurses and observed how they actually computed proportions
for medicine doses, they found that
the nurses used methods which were NOT those taught in school.
They were correct, but involved more steps during
which the person could keep the 'proportions' clearly in mind. I would
prefer medicine done by those nurses to ones done by a student tricking
to mimic a calculation learned in school but not digested into some 'big
picture'.

Annette Gourgey <statsense@RCN.COM>
I have an advantage in teaching statistics because the question of 'when
am
I ever going to use this' is more easily answered than it may be for
subjects like algebra or calculus that are taught with fewer applications.
But maybe this approach could be used with other subjects as well.
I bring in as many newspaper articles as I can find, to show how the
subject
is used in the real world. There is lots of financial information using
math of various sorts as well as statistics. I give a couple of leading
questions and have students discuss the articles in a CL group, or
in class,
or write something about them at home. I try to drive home the point
that
once they know some practical math, doors are opened to them. They
don't
have to take someone's word for it, but they can judge for themselves.
For example, is Bush's plan to privatize social security in the stock
market
a good idea? I give them an article that discusses it. The statistical
concepts in the article are average return and variation (volatility).
Once
they understand how these affect investments, they can make their own
evaluation of the president's proposal. I also give them graphs of
market
trends, poll results, etc. After 9/11 someone even wrote an article
about
probability and figuring how high your odds are of becoming a victim
of
terrorism (lower than you think).
Every day there is something interesting in the paper that uses math;
I just
file them by topic as I come across them and go back to the files when
I
need something for a particular topic.
I believe that, with some thought, realworld applications can be generated
for other topics in math as well. For example, I once taught algebra
at a
Manhattan school. I became aware that our street addresses, with our
numbered streets, followed a linear function. So I taught that function
in
a lesson on how the slope and intercept work. Another time I tutored
an
algebra student; just telling her that algebra prepares people for
calculus,
which can be used in engineering and building, was enough to help her
get
over her resentment so she could become receptive to the tutoring.
I think what makes math so hard is that it is so abstract. If it is
made
concrete, students have a much easier time making sense of it and connecting
with it.
My students really go for this. They say the articles are the best part
of
the course. Since beginning this I've never heard the complaint of
'when am
I ever going to use this' again. The only people that have given me
resistance over it are some math professors who think the only math
worth
teaching is 'pure' math.

I have comments in response to three of the posts to this thread, which
I'll
put together below.
On why learning math is so hard: I see students more caught up
with the
precision of math than they are in other subjects. The answer
has to be
exact and it has to be what the teacher wants. They don't seem
to have as
much of a sense of what it means in terms of their own internal sensemaking
as they do in other things I've taught (psychology, reading).
It seems to
be arbitrary and external to what is meaningful to them. My personal
opinion is that this has more to do with how math is taught than math
itself, but I suppose it is complex and can be debated.
On applications for algebra and other math topics: The Consortium
for
Mathematics and Its Applications (www.comap.com) has wonderful teaching
materials on this. They have lesson modules indexed by math topic
(basic
math, elementary algebra, precalculus, trig, calculus, etc.) that give
examples of realworld applications. The materials are classified
by high
school and college; the high school materials are excellent for
remedial/developmental math (e.g. I got some very good stuff on teaching
percentages from them). Some of it I never had occasion to use
in the
classroom because I didn't teach those topics, but I read just for
my own
enjoyment and expansion. One of my favorites was compound interest,
following the investments of two hypothetical people to see who ended
up
with more money and why.
I, too, have sometimes told people that even if they never like my subject,
they will get pride from doing something they never thought they'd
be able
to do. Some students have related to this, especially after seeing
their
grades improve as a result of their efforts. I've also asked
them why they
came to a liberal arts college rather than a community college or vocational
school, and what they think the purpose of that kind of education is.
I have to admit, though, that the answers to their question that are
based
on any form of "because it's good for you" are really answers for us
rather
than for students, who are usually not mature enough to appreciate
that yet.
That's why I like the applicationsthey're fun and they hit students
on a
level that has more immediate reality to them.

Hi Annette,
We have two developmental and two college level math courses.
The problem
we had is how do you take art and design students who may only know
arithmetic and prepare them for college level mathematics in two elevenweek
quarters?! There was no way we were ever going to cover all the
content in
a traditional Elementary and Intermediate Algebra sequence, (although
we
tried at first.) We had to ask ourselves what is important.
What do we
want our students to get from our mathematics course? Of course
we wanted
life skills, and to prepare students for their other courses for which
math
was a prerequisite, but we wanted more. We want them to be able
to think
and apply what they learn. We have found that most students
are able to
think conceptually even when their nuts and bolts math skills (arithmetic,
algebraic) are weak.
So first, I worked with the general education science and business
instructors and the directors of the major departments to find out
what
mathematics the students truly needed. I discovered they would
need only
about 25% of the content we were covering in our developmental courses,
and
we were not covering some of what was needed. So we bit the bullet
and
started eliminating content, choosing depth over breadth. It
wasn't easy!
As so much of math is interconnected, we had to be very careful about
what
we decided to include, so that students had what they needed to move
through
the curriculum. Next we looked for "reform" text books which presented
math
in context. We chose the texts by the Consortium for Foundation
Mathematics. We focused on the function as the central theme,
and
incorporated the TI83.
Our college level course is modeled after the Illinois Articulation
General
Education math course (IAI M1 904) and the General Education Statistics
course (IAI M1 902). (See www. Itransfer.org for more information
on the
IAI.) Our focus in these courses is more conceptual and less
technical.
They are far from perfect and we are continually modifying all of our
courses, looking for better ways to teach them and integrate them with
other
disciplines. (We include visual/creative projects with mathematical
themes
such as the golden ratio and spiral, tessellations, symmetry,
and
fractals.)
I would be happy to discuss this further with anyone interested.
As to the
a.k.a., I have known some who think my ideas are radical and antimath.
Maybe it is my UC Berkeley education!

That is an excellent point about the unpredictability of life.
I have a
story like that toonever expected to end up teaching statistics,
but a
tutoring job opened up, one thing led to another and then that was
what I
wanted to do. My original plan, to teach psychology, didn't pan
out, first
because of a lack of jobs and then because I developed other interests
that
grew out of the statistics tutoring (math learning, math anxiety).
Sometimes I've told students this story and they're always surprised.

"John M. Flanigan" <johnf@HAWAII.EDU>
I have given three answers to the second question:
Philosophical: Since you are in college, you are presumed to be seeking
a
college degree. People who have college degrees are expected by society
to be "Educated Persons." An educated person is one who has a broad
understanding of many things not directly directed at earning a paycheck.
(I often add that we are not just in the business of turning students
into
employees; we are in the business of helping students become Educated
Persons.)
Recreational: If you have a good, broad, knowledge of how various systems
operate, it makes thinking more fun. Understanding how things work
 from
economic plans and the behavior of people to ocean tides, seasons,
weather, and rainbows  is an enormous and inexhaustible source of
pleasure.
Practical: Other things being equal, advancement in any job, and access
to
improved situations will normally fall more readily to those who show
evidence of being Educated Persons  who can hold their own in written
and oral communication with others of various areas and degrees of
knowledge, and who can make decisions based upon broad knowledge of
politics, society, psychology, science, art, ...  whatever is appropriate
to the occasion.
This answer to the first question is from Stephen Pinker's _How the
Mind
Works_: "Mathematics is ruthlessly cumulative." In no other subject
is it
required to learn and remember *everything* from each semester in order
to
do well in the next. Students just aren't used to that stringent
requirement.

My response to the second question has two parts.
(1) You will always function several levels below the highest level
you have taken in math, as well as other
subjects. Raising the level you have studied will raise the level you
work at every day. You will see new and
easier ways to solve problems.
(2) You will be using the same problem solving skills in all areas of
your life. When starting the idea of
problem solving skills, I first plan a trip I want to take with them
 to show the relationship between the ski

When I was teaching world history I responded to the "why do we have
to
learn this" question this way. History and time is sort of in a spiral.
Events and things do get repeated but not exactly in the same way.
It's
very helpful to know how another time and place dealt with an event
and how
that solution worked or didn't work.
My best example to give the kids was the analogy of the advent of the
printing press and the advent of the Internet. We can learn a lot about
the
accuracy of the information that is offered by studying how the printing
press flooded the world with varying degrees of good information.
Kids seem to really understand the comparison to something that they
use
here and now.

Cynthia Breeding <cbreed@IO.COM>
For the second question I tried to think back to the 17 years I taught
math
from 4th grade to college age. That question was often used on me,
but I
never really had a pat answer. It is something a math teacher shows
more
than explains.
I always partnered up with a teacher in another discipline to work on
problem solving, project planning, job shadowing, anything that would
get
students involved in using some solid math in complex, but meaningful
situations, regardless of the level.
Once they get hooked, they will do a lot of symbol manipulation, practice,
etc., just to get to the next authentic thing.
It is true that people can live a very satisfying life without algebra
or
any higher level mathematics. But they never know what a fantastic
life they
can have if they know how to do some math!

I forwarded your posting on this subject to my son, who is in his third year of math studies at the University of Waterloo in Ontario, mentioning that you are a math professor.
While he quickly followed his reply (which I am reproducing below) with a second message saying he realized that he had not actually answered the question, I found his comments interesting and thought you might as well.
I am somewhat in awe of the mathematical bent of both of my children (my daughter is still in high school) and enjoy hearing their thoughts on what it is like to understand math.
Anyway, here is what he said:
"I believe the most accurate answer to this isn't much of an answer at all. It's really just something you're born with, it seems. Certain people understand certain things which others don't. For example, even within the math faculty, I find that there are 2 types of people: those that understand algebra, and those that understand calculus. Less than 1% of math students at UW understand both. So an algebra person might ask a calculus person why calculus is so hard, and the calculus person won't have a clue what the algebra person is talking about.
That doesn't really address what to tell them though... I know most
people wouldn't be satisfied with "it's just a different way of thinking".
With luck, it might give you some ideas though.There, now you can post
to the list! You might even mention that your son is in combinatorics and
optimization. Since he's a math teacher, there's a chance he'll understand
that."

Content vs ... It sounds better in French: "contenu vs contenant".
If you're the typical math major, or taking less university math than
that, you have as much chance of hitting the lottery as "needing" calculus
in later life. You're "only" developing your mind's ability to function
when you take math. This is not unlike the runner who exercises not because
he's training for the olympics but because "it's good for him". With this
training under your belt you can do anything. I tell every one of my students
that if they can get a B+ in my classes they can do anything. And they
believe me. A specific case of "contenu vs contenant": the difference between
a bachelor's degree in administration and an MBA. You cover somewhat similar
material, but not at the same intensity or tempo, since in an MBA you're
supposed to already know how to work and think. This is somewhat related
to the futility (or waste of time) in doing a second bachelor's degree,
for most thinking people.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
"Arthur L Crawley" <acrawle@lsu.edu>
Ted, the rub you speak of is true for all disciplines. However, I do
believe it is in the language of mathematics, the use of signs and symbols
to make sense of reality which is stressed, e.g. e=mc2 that makes mathematics
"so hard" . "A solution" is to connect your disciplinary understandings
to real world problems, thereby making the theoretical visible and accessible
to our learners. Because some of our students (those that are often more
like our faculty it's called replication) get the abstractions quickly
and may not prefer the collaboration of peers or practice to deeply understand
the concepts and the thinking involved. I
believe many of our undergraduate learners need concrete examples and
hands on experiences before the theoretical abstractions can take hold.
Good teachers build a bridge to those learners and in doing so help
both types of learners make sense of what they observe, know, understand,
apply, and may I add, value. And it is simply more fun and motivating to
the majority of our students and to the professors to do so.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
"Theall, Michael" <Theall.Michael@uis.edu>
A quick response: I try to find relevant, realworld situations where
the
content can mesh with some necessary or meaningful task or set of conditions.
Here's my example.
My son took chemistry last year (as I did in high school and then,
in
college). We both were taught in the same way, learning the terminology
and
doing things like balancing chem. equations. Since 1961, I have never
had
any occasion to balance another equation. My son will be a music major
and
the same will likely apply to him. What both of us would have profited
from, would have been the connection of chem. to something more relevant
than a lab experiment and the periodic table. An ecological approach
would
have helped both of us to understand the how and why of the subject,
and to
see how its workings affect us on a daily basis. This seems important
particularly in high school courses and/or for those who will not be
directly involved with chemistry as a professional field. I'm not proposing
that we drop the theory/science, just that we treat it in a different
way
for those who do not intend to go into the field. I know some will
say that
this idea somehow violates the sanctity of the subject or is pandering
to
less able students. But the issue you raise is not how to make great
chemists or mathematicians, it's how to get the larger population of
students (probably with weaker background or interest levels) to be
willing
to invest the time and effort necessary to acquire the necessary knowledge
of both the content and its importance. One way is to make the content
more
meaningful and thus, more understandable. Another is to be willing
to teach
those not gifted or initially interested in the field. Courses that
have
the purpose of weeding out 'those who can't hack it' serve only elitist
purposes. As Lee Chronbach said, education should be a talent development
effort, not a competition.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
"Ann J. Pace" <paceaj@UMKC.EDU>
I thought that Edward Thorndike found nearly 80 years ago that there
was no support for this "mental discipline" perspective,
i.e., that the learning of certain subjects such as mathematics enhances
thinking generally. Also, hasn't much more recent research on thinking
and problemsolving pretty much discredited this general transfer view?
(An exception would be the kind of general heuristic represented by IDEAL,
which has wide applicability as an approachtotask, if used explicitly.)

Catherine Scott <c.scott@UWS.EDU.AU>
Why is maths hard to learn? Because people do not want to. Why don't
they
want to? Because people work on a need to know basis for deciding what
to
learn and they do not think they need to know most of what maths teachs
them.
And unlike other irrelevant but verbally based material, there is
insufficient redundancy or 'commonsense' in the material to allow them
to
'surface learn' sufficient to get through the final exams. To even
scrape
by they have to work quite hard.

This is actually a story of trying to pick up on the end of your
response: "... very few real world problems modeled through math that
most people
would encounter." And, yeah, my response has not received ovations.
STORY: Schools that have a 'core curriculum' (especially if it is BIG)
Can get into very interesting discussions of 'how much this', 'how
much
that' in the core. In the late eighties, in preparation for a North
Central
visit, some of us proposed a multidisciplinary core course discussion
of
human development (maybe count it as a social science?). Question #2
was to be addressed, if not explicitly, at least as part of a tradition.
We
almost succeeded in gaining consensus, except that the course was NOT
a
part of the tradition... go figure. Some of us suggested that what
was
being learned about learning and about the use of tech in addressing
needs of those with disabilities as well as others SHOULD become part
of a new
articulation of the tradition. Didn't happen, but the question was
raised.
Math models of learning and human development would have been included

computer simulations and some artificial intelligence topics as well.
The implications about learning/teaching styles and predominance of
'lecture' style, in my opinion, became a basis for 'wait and see' and
allowing
more time for further research, discussion, etc.

The earliest Math we learn is in "number concepts". If you don't know
how
to add, subtract, divide and multiply, then how are you going to carry
out
life? How do you assume what your bill should be when you have been
sitting in a restaurant or bar for hours? How do you work out your
"savings" when something is 25% off? How do you know your Telco company
isn't ripping you off?
Larger scale. Let's assume AT&T, because most listers here are probably
American, charges an extra one cent on everyone's monthly bills for
2002.
That's twelve cents per house, and let's work with 30% of your population.
Now you're talking about approximately 75 million people? Am I right?
250 million in the USA? Seventyfive million people. That's a profit
of
$900,000 for doing NOTHING! There's your economy of scale.
How about physics? A penny dropped 6 inches will barely be felt. A
penny
dropped from the top of the Empire State Building would kill you if
it hit
you on the street.
Math is integrated in everything we do. Introduce them to Fibonacci.
He's got explanations for most architectural concepts. Show them a
crosssection of a pinecone. Fibonacci has an explanation for the
spiral.
As for it being abstract? I would say it is ENTIRELY the opposite to
begin with, and only becomes abstract in upper division multiplication
at
the university level. LOGIC is NOT abstract. It is sequential.
What grade do you teach? Your response may not be wellreceived because
of the grade level you're explaining it to. Perhaps they don't know
what
you're talking about. I'm really lost when you say that "there are
very
few real world problems modeled through math that most people would
encounter". I challenge you to come up with any sort of problem having
to
do with construction, destruction or technology that does NOT involve
math.
And learning math is only hard if you're a rightbrained person. Talk
about left brained and right brained people because the right brain
controls your ability to be "creative" whereas your left brain controls
the "logic" that we need in our daily lives. Learning math is EASY
for
many people and difficult for many others. Maybe the onus is on us
to
make it easier for those who have difficulty. Perhaps we need to explain
it in other ways instead of "our way" which we have a tendency to fall
into.

Two answers that frequently fit:
Q. Why is learning math so hard?
A. It isn't. We just make it that way as we have no idea how to connect
it
to anything remotely useful as we really don't know how to do so ourselves.
But we like to tell you how important it is.
Q. What the heck do I need this for?
A. You don't need it for squat because we obviously have no idea why
you
would need it or it would have been obvious in this class. But it makes
us
feel important.

What you did is the way I handle it on the first day of class.
My question to the students
is "Who feels they are going into a field of work where they will not
need math?" I have
had very little trouble showing were math was necessary in almost any
job and then I show
them that the more education they seek, the more math they will need
(Statistics, Operations Annalysis, etc.).
So the more we know about the practical uses of our subject, the better
we can explain
it to our students. Yes it helps you think better (and can be
just plain fun) but that is not
what our students want to hear.

Answering this questions has been my focus for almost two decades. In
grade 10, some eighteen years ago, my math teacher told me that I couldn't
count. I took this at face value and accepted it as truth.
What other
options do adolescence have?
His proclamation haunted me for most of my adult life. At at the
age of
30, I returned to university to try to discover why learning math was
so
hard and if I was truly incapable of doing so. My curiosity has
led me to
consider the discipline from multiple perspectives. It is my firm belief
(and my thesis topic!) that as educators we fail to make the critical
connection to the reality that mathematics is a language and as such
should be taught using the theories and principles of second language
acquisition. The abstractions need to be taught in a language
students
can understand  clearly with the intention of ultimately developing
the
formal language. It is ultimately the educators responsibility
to
facilitate this code transfer.
I would suggest that this might make learning mathematics easier.

What a wonderful thought! When taking Linguistics as an undergraduate,
I
discovered that solving linguistic problems was akin to algebra, only
with
words. Looking at math from a linguistic perspective would make it
so much
more accessible to people like myself who barely made it through high
school
math and undergraduate statistics. If I could find a math teacher who
used
this approach, I would cheerfully retake high school math and may even
dare
some university level courses simply to prove to myself that I'm not
mathematically stupid.

Walter Whiteley <whiteley@MATHSTAT.YORKU.CA>
Let me jump in with a slightly contrary view.
[For other listers, I should indicate that I have worked with
Donna, so some of this will not be a comlete surprise to her.]
In the human brain, it appears that much of mathematics
is NOT done in the language parts of the brain,
(though some parts, such as memorizing multiplication tables
do seem to be). More of it is done in the visual / kinesthetic
parts of the brain  the parts that do eyehand coordination,
and seem to include an analogue number line, active at age 3 days.
[See books by Butterworth: the Mathematical Brain, Macmillan, 1999;
Dehaeme: The Number Sense Oxford University Press, 2000 ... ]
Of course, many texts and some teachers filter the communication of
math through language, either surpressing the true visual nature
or mangling the visual forms by showing them without teaching them.
When using visuals, teachers and texts tend to ingore the fundamental
observation that different people to NOT see the same thing when
staring at the same image (something that is even more true with
moving and dynamic images). As the Cognative Scientists teach
is:
we create what we see. We see, in part, with learned attention
to some features and learned ignoring of other things.
This learning, including learning to shift attention, is critical
to how we extract information from visuals in math, how we
do math in visual forms, etc. It is learned, but iti sseldom
taught.
Algebra is a particular example of what, to me, is a highly visual
area of mathematics. I say to my students that algebra is about
cosmetics, not about surgery. Many ways to change the appearance
of something, changes that shift my attention and suggest further
steps and transformations, without changing the underlying content
(i.e. what the 'solutions' will be). I am working on a
power point
presentation which illustrates some of this, with the working title
'On Picture Writing'  the title of a famous little article of George
Polya, who wrote 'How to Solve It' and 'Plausible Reasoning'.
I note that failure to at least show visual mathematics as one
possible way to do math causes serious damage to the diversity of
people practicing mathematics. It excludes people with certain
packages
of abilities and disabilities (e.g. certain forms of autism and
dyslexia), it gives a dishonest public face to what mathematicians
like me actually do in the quiet of our offices or group convesations,
etc. In the process, it drives away, in the transition through
high school,
many of the students who, by final year undergraduate studies could
be the
most efective and creative.
All of that does not say that the analogy to language is going to
be irrelevant. One is learning a complex cognitive skill.
Even
language uses multiple parts of the brain (text and context).
It is, however, only an analogy. Visual Literacy is also only
and analogy, but it gets some necessary first steps taken.
Some people even talk as if one can only think with words.
Aristotle spoke otherwise. He said (in translation):
A soul never thinks without a mental image.
We do think with images, at least as much in mathematics as in
any other field. [Images are not scattered into pieces on
leaving the eyes  those externalized parts of the brain.
We create true maps of images in the visual system, V1, as
well as many decomopositions in other parts of the visual system.
Moreover, in the mind's eye we use words and associations to
cause such images to appear, to rotate etc. See Kosslyn, Image
and Brain,
MIT Press 1996.] Whatever happens in the brain, as we do math,
must be reusing parts of the brain evolved in humans prior to
the evolution of math. (See Lakoff and Nunez: Where Mathematics
Comes From,
Perseus Books, 2001.)
For a dramatic autobiographical description of this, see the book:
Temple Grandin: Thinking in Pictures: my life as an autistic,
Vintage Books, New York 1996. (Grandin is a university faculty
member,
and I have had autistic graduate students in mathematics.)
I have some larger powerpoint presentations under the title:
'to see like a mathematician' and recently had a short article
commissioned and accepted by Time Educational Supplement on this
topic. Sometime later this spring, I hope to put these (and others)
on my web site, with annotations, for downloading. I have been
teaching a first year seminar on 'information in visual form'
and it is truly fascinating how we can change the way we see.
This too has a profound effect on how we do mathematics and science.

Julie Sessions <JUSESSIONS@AOL.COM>
I was thinking along the lines of what Jerry said. Ask your student
at what age he was able to start
seeing his future and if he could read yours. This usually gets
a laugh but also gets a point across. I
never thought I would go into a field that would require math and science
because I had such a hard
time in middle and high school with them. I picked social work
as my beginning major but after 2
years switched schools and got a nursing degree. Needless to
say my math and science teachers
from high school were dumbfounded because they saw how hard I struggled
with both subjects.
Nursing isn't for me though and had to get out of it and work only
occasionally just to keep my license
up. Too much lifting for my back. So, when kids say, "why
do I need this? I will never use it." I am a
prime example of why they sho! uld never say never.

Shevawn Eaton <CD0SBE1@WPO.CSO.NIU.EDU>
I have hear students ask this question about much more than math....why
do they need to take gen eds, why does the university think they need
all those stupid "core requirements", why does the university allow
this
old/insane/incompetent/incomprehensible/whatever person teach that
course that everyone has to take?
My response, which always gets a laugh and gets students out of
their
victim mentality is simply this....
Because you need to be in courses that will build your character.
Hard courses, seemingly stupid courses and courses that are badly
taught all contribute to one's character in a very positive way.
They
test your perseverence, your tenacity, your assertiveness and your
will
to survive! It is a phenomenal accomplishment to succeed under
such
circumstances and you have to develop a number of skills in the process
that are as much a testament to your fiber as they are to your capacity
to learn XXX. And those life skills are the important ones.
The next time you encounter something difficult, regardless of the
reason, you know in the fabric of your being that you can do this
because you got through that awful (fill in the blank) experience in
college. If you got through that, you can get through anything!

Janeane Weprin <weprinj@AII.EDU>
Hi Listers,
The question "Why is learning math so hard?" is closely related to the
question "What do I need this for?" I would like to address the
latter
question.
I was a math teacher for years. (I am now the Director of General
Education
at our college.) I have had to answer this question for my students
and for
myself. I have attended numerous mathematics conferences in which
many (too
many?) sessions are devoted to convincing students that what we are
teaching
is important for them to learn. Why do we have to try so hard
to justify
what we teach? Why does the subject not justify itself, if it
is so
important? Something is wrong and something needs to change.
Is there
perhaps some truth to the idea that students do not need as much math
or the
type of math that high schools and colleges require? Are we using
math as a
filter? Perhaps it should be an elective? Imagine a math
classroom filled
with students who really want to be there.
It often seems to me that we assume everything we teach is important
and
then find the justification, rather than determining what is important
and
then teaching it, essentially putting the cart before the horse.
Much of
education is a selfperpetuating system  things are the way they are
because this is how they have been for years. I know that there
are
educational systems in other countries in which students are awarded
baccalaureate degrees and which require no mathematics beyond arithmetic.
I
am not arrogant enough to say their degrees are less valid than the
ones
granted in the US. I think we may need to step back and reevaluate
what is
truly important. I believe we are still too content focused,
with content
often separated from context. I believe the academic disciplines
remain
artificially separated. Is it surprising our students are not
able to
integrate and synthesize information when they have been taught each
subject
separately most or all of their academic careers?
Trying not to be hypocritical, at our school, we have created a mathematics
curriculum which is focused, integrated, and applicable to our students
majors and lives. Our courses are not easy, to which our students
will
attest. We emphasize math in context and as a tool for problem
solving and
understanding the world. We rarely get the question "What do
I need to
learn this for?" any more.
+++++++++++++++++++++++++++++++++++++++++++++++++
Helmut Lang <langhr@UREGINA.CA>
Math teaches students how to think. Really?
Ann Pace raises a valid observation regarding the theory of formal
discipline. However, even if the product of learning to think
occurred,
that which is transferred may well be low level. Too often, school
math is
little more than memorization of steps. If one uses the chesnut
taxonomy
of Ben Bloom (other taxonomies could be used), memorizing steps is
at the
RECALL level. Students then follow the steps to solve a problemthe
APPLICATION levelbypassing COMPREHENSION. Too few math teachers have
students ever operate at the ANALYSIS, SYNTHESIS and EVALUATION levels.
Teaching for thinking? Hardly. Teaching for transfer?
Hardly.
++++++++++++++++++++++++++++++++++++++++++++++++
Michael Agostini <michael@HEZEL.COM>
Ted,
Often I think students ask why they should study a subject when they
can't
understand how that knowledge is used outside of the classroom.
Perhaps
each student will not use all the concepts studied but at least knowing
how
other people use the concepts may help demonstrate the value. One way
to
help them make that connection is to explain to them the kinds of
professionals who use each of the math concepts being studied and how
they
use these formulas/theories. Inviting an engineer, physicist or economist
to
your class to share his/her work and give some specific examples of
the
problems they encounter would probably be enlightening to your students.
Having students solve "real" problems by using their math may be more
effective in demonstrating the value of mathematics than trying to
explain
some of the intangible benefits. At the K12 level, an organization
called
National Math Trail (www.nationalmathtrail.org) is showing teachers
how to
help their students apply basic math concepts to the world around them
and
incorporate technology into this learning process.

"Navarro, Virginia L." <virginia.navarro@UMSL.EDU>
I wanted to share an example I use with my students to illustrate Ann
Pace's
and Helmut Long's points. As a reasonably good student and school
gameplayer, I successfully completed high school geometry at a private
college prep school. Theorems were like puzzles to me; all the pieces
needed
to fit together in a certain way. I had absolutely NO CLUE about
what
geometry was for, about, etc. As a result of this failure to
move to a
"scientific" from a "spontaneous concept understanding (to borrow from
Vygotsky's notion), I never built on my geometry knowledge despite
my
academic meaningless A. It became dead knowledge in the worst way in
that it
was unavailable conceptually to move my cognitive functions forward
in new
situations. Transfer, I believe, is vastly overrated when dynamic
conceptual understandings are never achieved.

John Mason <j.h.mason@OPEN.AC.UK>
I suggest (and i tested this out numerous times) that when someone
askes "why am I doing this?", "what are we doing this for?", and
other variants, it signals lack of confidence, loss of facility, loss
of selfesteem. I find I never as these questions when things
are
going well. I suspect that others are similar. So when
a student
asks it, I choose to treat it as a statement: "I can't do these
questions", "I am lost".
How did I investigate this? I trained myself to answer, without
batting an eyelid and remaining very still having given my answer,
that "It is absolutely vital in the steel industry". That
of course
dates me, for it was tat a time when the UK actually had a steel
industry. Students facers went absolutely blank. This was
clearly
not what they were asking. Try out a version for yourself and
I am
confident you will see that they were not asking for applications,
nor for some philosophical justification in terms of mental powers
etc..

Suskie, Linda [mailto:lsuskie@TOWSON.EDU]
Ted, your second question is REALLY relevant these days, as we're
discovering that many students, in particular many students from
nonEuropean backgrounds, learn better (i.e., achieve deep, lasting
learning) and more easily when they can relate a topic to their own
lives
and what they have already learned. I think that's why some students
have
so much trouble with math. I wish every teacher began every year
and every
unit by explaining why we're learning this and what impact it will
have on
us.
I'm probably going to draw flames from the math teachers for even bringing
this up, but I'm starting to question more and more why we have the
high
school math curricula that we have. For the thousands of high
school
students who will never need or take calculus, are binomials, geometric
proofs, trigonometry, and their kindred really the best ways to achieve
the
ends Ted describes? Could we achieve many of the same ends through
an
algebrastatistics sequence, which would have the advantage of being
far
more relevant to most students? (And better prepare those interested
in the
social sciences and health sciences for college?)
++++++++++++++++++++++++++++++++++++++++++++++++++++
James Allen <allenj@MAIL.STROSE.EDU>
I find Linda's suggestion regarding the traditional math curriculum
very
interesting. As a former secondary math teacher (5 years) and a former
math
learning skills counselor at the university level (6 years) working
with
students in both math/science and social science majors, I also began
to
think along the same lines as Linda. Based on my teaching experience
(and
not being aware of the relevant research literature on this topic),
it seems
that much of the secondary math curricula does not serve a majority
of
collegebound students well (and even less so for those who do not
attend
college). The traditional curricular sequence does seem to be a benefit
to
those who choose a major in which Calculus is a foundation (Math,
Engineering, Economics), but not for most liberal art and social science
majors. However, the most likely alternative (early "tracking" of students
into nonCalculus sequence) is not one I favor either. I've come to
believe
that it might be more beneficial to focus on very fundamental structural
components of all math. For example, an extensive and deep understanding
of
the nature of "patterns" that is found in any branch of mathematics.
I think
I am arguing for a "less is more" (depth vs. breadth) approach to the
teaching of math, where the "less" that is taught is focused on the
fundamental structural elements of mathematics. From my limited knowledge
of
upper elementary math curricula, it seems that this approach is attempted,
but is dropped (perhaps too quickly before it is deeply understood)
once one
begins a secondary sequence in math. From a cognitive development
perspective, I would hypothesize that for many students the focus on
"patterns," etc. might be more appropriate at an early secondary level
(8th10th grade).
I'd certainly be interested in hearing from math curricula experts or
anyone
on these lists that is knowledgeable about research in this area.

Scriven@AOL.COM
It may be time to say that this is a bad question. It's not hard for
some, is
hard for others, and there's always something that's hard for everyone.
I got
conscripted into mathematics because I needed it to become a flight
officer
in the air force, but managed a couple of degrees in it when the war
was
stopped with an oversupply of pilots, leaving me with nothing to do
but go to
college. But I'm hopeless at music and Latin. And some parts of mathematics
are very hard for me, others easy.
The only good question is how best to teach it. Even there it seems
clear
that what works for some does not work for others. And I take it that
at a
general level the answer is much as people have been discovering throughout
education; there has to be a very large amount of highly interactive
process
with frequent evaluative feedback, its content highly individualized
to the
interests and ability level of the student. This isn't hard to do unless
you
insist on highly heterogeneous classrooms (by ability/achievement level)
and
won't use both games and the programmed text approach on the computers
that
are being underutilized.
Oh, well, nothing new about this...

David Warlick <davidwarlick@MAC.COM>
Ted,
I taught math my first year as a teacher. The year went so badly
that
by Christmas I registered to take the civil service exam so that I
could
become a rural postal carrier. I would like to address your second
question, because it is one that I think about a lot. The simple
answer
is that we teach what we do and students learn what they're taught,
because someone in the state capital put it on a set of standards,
and
they probably put it there because they were taught it in approximately
the same grade.
I suspect that there is much that we are teaching that will not be of
use to our students, and trying to rationalize it only degrades our
profession in front of them. "How many long division problems
have you
performed on paper in the past month?" I believe also that your
justification, although true, is a little lame as well. If we
are
teaching students to think, then we should teach them to think within
a
context that is relevant, if not to their future, then to their current
lives.
My answer, although I haven't had the opportunity to express it
compellingly yet, is "context". Students should learn science
in order
to understand the context of their being, where they are, and where
they
are going  why the world behaves the way that it does. We teacher
social studies, which is in no way less important, for the very same
reason, to create a context for our being, who we are with, and with
whom we are going  why people behave the way that they do.
It is all
in order to sustain and enrich our culture to create a higher quality
of
life.
The question we should be asking is not, "why are we teaching what we
do?", but, "what should we be teaching?"
Exactly two cents worth!

David wrote, "If we are teaching students to think, then we should teach
them to think within a context that is relevant, if not to their future,
then to their current lives." I agree. My 3rd cent is:
it's most important
that we find context in their current lives. It's there to be
found, I'm
sure. There may be different relevance for later in their lives,
but if
there is any relevance for their lives today, we should find it and
use it.

Negative attitudes......Having the fruit without the tree.
The study of mathematics is not only a practical art it is a theoretical
art. It is has been used as a tool to improve the quality of life.
Many
professions such as engineers, doctors, and even businessmen have uses
some form of mathematics. Mathematics is not limited to numbers; it
expands to logical, reasoning, and/or critical thinking. Although I
have
not used long division in a number of years, this algorithm has
contributed to the development of my cognitive skills.
Furthermore, speaking of relevancy, I can not recall the last time I
used the word cantankerous, yet it was a requirement for succeeding
in
my language arts course. It seems that it is "okay" to question the
level of mathematics that is learned, but not the level of language
that
is learned. It seems that it is "okay" to have poor skills in
mathematics, but it is a tragedy to be a poor reader. Double standards?
In my experience, I have observed that poor mathematics student were
generally poor readers and have had bad attitudes towards mathematics.
Could this be a result of the negative attitudes conveyed throughout
our
modern society?
I believe we must prepare students for the future as well as their
current lives. After all, a mathematician initiated the concept of
the
computer

I agree with David. The point of some math textbooks is more of the

guess to simplify things in many school systems, there is but one way
to do special kinds of math.
I am proud to say that my school children learned math in many different
ways, understanding that in
the system there was a preferred way of doing things, but with the
freedom to get the answers in a
variety of ways. Two of them are currently in math and technology at
Berkeley.
Here is what happened to me. I was teaching base 2, 5, and some other,
as the book prescribed and
this child sat and made a database taking this learning
through 25 different numbers. It was then that
I decided I had to let math children have wings. So I started doing
other kinds of math instruction as a
part of the
work I do. Interdisciplinary problem solving, content related.
I also did a day which was not drill and kill math. I also used as many
math game programs, and
simulation projects as I could. We spent a month once working any time
we had a free period or time
in learning to beat the computer using probability, and with some lessons
on geometry where you had
to apply the skill, and the simple kinds of problem solving that used
to be only for the gifted and
talented,
I found web sites with special resources but there was at the time also
the National Geographic
Kidsnetwork , which was also a different kind of science, math and
geography.

My former high school pondered this question. We were looking
at making all curriculum meaningful and relevant. The math department
decided to split the traditional math track after geometry. They
offer the traditional calculus/stats class and as a companion class offer
and "advanced applied math/stats class." The kids who are interested
in engineering/technical stuff do the traditional trace, while the applied
math is geared to the medical/science applications. The hs has 5
PhD's who left the "professional" world to become math teachers (they laugh
when they say that!!) There is one biochemist, one industrial chemist,
one "techie" (holds multiple patents for computer stuff!), one theoretical
math, and one in philosophy  they worked together to redesign the course
structure and as a result have increased the numbers of kids in upper division
math classes by almost 60% in 2 years. Lots of kids who didn't want
the calc approach are taking the applied/stats approach and loving.
The math profile scores from the SAT have gone up by almost 25 points in
the same 2 years  so we have more kids taking the test and still there
is an increase. These same math teachers convinced the lower division
teachers to include math vocabulary and math research into the curriculum,
so kids are learning the vocabulary & skills to actually do "word problems"
 so across the board these kids problem solving skills are going up by
working on the concepts that literacy requires application.
Interesting thing about the high school, is that 3 of the 5 teachers who did the revamping have left the school and gone on to other teaching positions. Yet the success of the "experiment" is paying off with more kids feeling good about math. As a math phobic, I really, really appreicate that!!!
So, Linda, I hope that you and I both don't get burned!!

I thought about this title again . I am at SITE. I have had the priviledge
of
attending some workshops on thinking, teaching, learning , and retention.
What do we see as math? How do we define it? FOr some of us it is the
way we
were taught , so theoretical math, problem solving, thinking math may
be
areas of difficulty for us. Often the way we were taught frames the
way we
understand math.
What do students see as math? Do they realize how in their daily activities
math is used. In the TIMMS studies it is said that we teach math a
mile wide
and an inch deep.
As a teacher I might also be bold enough to say that we teach it on
the
calendar and the same kinds of subjects are left until the end of the
school
year a lot if we do not preassess and always follow the book.
Theoretical math can be taught in a lot of different ways. There is
www.enc.org to help. There is math forum , there is learning to problem
solve, there is thinking about the use of math in real life, real time
and
involving the students in thinking math activities as well as hands
on
demonstrations.
I am proud to say that I was often ridiculed for doing hands on math
past the
third grade. I am proud to say that I used games and software and problem
solving nearly every day in some way.
I even used cuisenaire rods when they were no longer the fashion, and
so I
had them when they came back in.
Parental use of the software, projects, and handson also was a help.

Math is hard because we approach it as if we lived in the 19th century
not the 21st. In the 19th arithmetic was the most basic and essential
tool for higher math. One major accomplishment of the 20th century
was to eliminate the need to labor over complex arithmetic and use
calculators and computers to increase accuracy and allow theretofore
computations. The 21st should build on the 20th, not regress
to the
19th.
Consider the typical school curricula where children take up to 4
years to learn basic arithmetic computation. It is a grueling
process
that turns off many children and is never mastered by others.
I have two questions of my own?
1) How much of what we call math disability is simply arithmetic
disability?
2) If arithmetic were invisible, what math would you teach a first
grade child?
I think math should be taught with a two pronged approach that
reflects the world in which we live.
Think about how you deal with the bill in a restaurant. You do
not
add to the nearest penny, but estimate. On the other hand, if
you are
doing accounting and need accuracy to the nearest penny, you use a
calculator or computer. This is the way children should be taught.
Rather than memorizing tables and learning to "carry", "borrow", etc.
teach a child to estimate answers, first with single digits then
multiple. Grade a child not on how many answers are perfectly
correct
but on how close the child is to the correct answer. If absolute
accuracy is required teach the child to use the tools of the 21st
century. If the child is allowed to practice estimation with
immediate feedback, they will learn to be totally accurate not only
with the usual tables but to a certain extent two digit numbers.
In
addition, they will also be within 10% accuracy in the estimations.
My preferrence is to teach math with a spreadsheet which makes
arithmetic invisible and allows a child to concentrate on mathematics.
I have also developed a prototype spreadsheet to teach estimation.
If you are interested, take a look at
http://www.enabling.org/estimate/estimate.xls
I have not tried to use this on a computer that does not have the
Excel spreadsheet program and would be interested in feedback on this.

Ted,
The main reason I've seen to have kids study higher math, above that
which
is daily practical, is to find out who can go into the discovery science
part of math. Only the strong survive, but society as a whole needs
those
strong to survive, and we need to find potentials to that end and help
potentials develop.
But, sadly, I'm not very good at teaching math, tho I can do a great
job
with technology, reading, and a decent job with social studies, and
the
simpler sciences .... I was a good math student in and directly after
high
school, but "lost" the ability during adulthood, and was never any
good at
explaining what I could learn ... There was a time when I could figure
interest compounded daily using logarithms .... now the computer does
it
for me when I happen to need it.
In your joke, the example of "new Math" from the seventies(?) was
priceless! I was a parent during the "New Math" phase ... and
remembered
the remediation in late middle school so the kids could learn computation
so they wouldn't bomb in high school ...
Perhaps the answer is "you learn math because society reflected in the
experts and politicians wants as many people to learn as much math
as
possible, so that society will always have mathematicians." ...
Perhaps for the same reason that we study Philosophy .... so that the
study
continues through our society ...

Ted, ideally, I would always try to set up a scenario in which the student
spontaneously recognises the need. I n my children's "free" primary
school (sort of John Holt style)the teacher and kids would establish a
"village" (Greek, mediaeval, whatever) and building
(geometry) shops, trade, money and maths would inevitably naturally result.
It was brilliant! Higher maths happened more formally, but often in the
context of play (what other purpose is there for pure maths?).

"What the heck do I need this for??????!!!!!" (As a Serious Question.)
I trust you will receive many other replies, but here is my two cents.
Two possible ideas come to mind.
A sincere question of concern from your student.
A question to simply escape the reality of
undergraduate education.
I use a simple eyetoeye check to decide the status of the question,
especially in precollege level
(Algebra I & II, Intermediate Algebra). I hear this question
in all other nonCalculus theme
courses as well. So, you are in good company.
For your question I think I would reply with a short comeback such
as
" ... this is an excellent opportunity
to add to your extra credit work. I think a research of
the uses for Mathematics in the academic area
you are electing to pursue is a choice for
you."
(Partly tongueincheek, but effective in placing the ball back in their court!)
The recent years I have been offering Bonus options ("free" to choose,
only positive points). This
question, when a real "concern", fits the criteria for extra work and
I would offer it for "Bonus"
point(s). A real career analysis project! It says to me
I an no longer the "authority" guy, and
allows "free" research project assignment to bring to class a answer.
(Being fair, this could be
offered to all students individually, or possibly as a teams, dividing
the class into pairs or three
person teams.
Recently, I even held a class vote (ala Florida results) on the Bonus status (yea or nay).
I have used this approach to answer wellmeaning ideas (reinforcing
"critical thinking") with some
success. Weak students still avoid these chances to bring their
other skills into use. When asked
by a student not contributing to the class, I have to carefully weigh
the odds that a question is the
"sidetrack" attempt rather than their sincere concern. (Happiness
is when a "responsible"
learner accepts accountability for issues they present to the class
and follows through with
a reasoned solution.)

Luckily, the last time a kid asked me this (in front of an entire class

boldly asked, "What's your major?"
She replied, "Music." Whew! I had an earfull for her!
Everything from the musical scale to how they
use logarithms to fade out the songs on a CD.
No one else had the nerve to ask me that again... that semester. 8)
Yeah, the pat response of "it trains you to think" usually falls flat.

care about thinking.

CKMont@aol.com Cal Montgomery
I've generally either made a joke ("you should study logic"  my area
 "so
that when you're hanging out with people you want to impress, you can
make
what look like complex statements about things you know little about,
that
are actually tautologies, and you'll never get caught in a mistake
and people
will think you know more than you do") or gone for some kind of application
that looks like something the students might use, for at least some
examples
(we'll leave out the Venn Diagram Dating Service, in which the men
were
classified according to the standards Tall, Dark, and Handsome <grin>).
Two realworld examples:
1. When working in a store in a mall, I had to make up weekly
schedules for
employees' shifts. Each week the home office gave a total amount
of money I
was allowed to spend on payroll; I was given a list of employees
who were
salaried and therefore entitled to a certain number of shifts of a
certain
length each week. Other than that, I had to assign workers to
shifts that
they could work, according to store need and according to their pay
rates.
If P is the amount I'm allowed to spend on payroll, and S1 and S2 are
the
weekly salaries of salaried employees, then I had P(S1+S2) dollars
to spend
on parttime workers. If some workers are getting paid at H1
dollars an
hour, others at H2, and still others at H3, then I have x+y+z hours
to hand
out, where x*H1+y*H2+z*H3=P(S1+S2). (Obviously, this permits
a range of
values for x, y, and z.)
Note that if better workers are paid more (which was not necessarily
the
case, and I need a certain number of hours just to cover the store
(to ensure
that there is always someone on the sales floor to discourage shoplifting),
and P is low for the week, I have a strong incentive to give the most
hours
to the worst workers. (There are shifts when all you want is
a body; there
are other shifts when you really don't want the worst workers you have
running things.)
Note also that, knowing how many hours I need coverage on the floor,
I can
make a case for going over budget in a given week before I start preparing
the schedule  and, looking ahead (and knowing the formula which gives
me P,
based on sales targets for each week), I could also give predictions
about
when I could get labour dollars (year to date) back under the allowed
amount.
Aside from this, I had to report, each week, how much our goal was (the
amount of money brought in during the corresponding week the previous
year),
and how much our goal to date was; and also how much we had indeed
brought
in for the week and for the year to date. I then needed to compute
the
percentage "up" (over goal) or "down" (under goal) we were for the
week, and
for the year to date. A good grounding in basic arithmetic allowed
me to
"eyeball" the figures and catch bad errors. My boss, on the other
hand, who
had never encountered the word "protractor" before (we sold some educational
toys and a customer asked her in front of me), couldn't do that.
And when
you report that you're "up 45%", when your goal is $2,165 and you brought
in
$2,243 (this is just a random example), you're going to hear from your
district manager, and she's not going to be happy.
Note that this was basically a minimum wage job. But being able
to do these
things meant that (a) I got more of the shifts where documents for
the home
office were prepared than I otherwise would have (bigger paycheck)
because I
was good at preparing them, and (b) I had a lot more control over my
work
schedule than I otherwise would have because I often made schedules.
(And,
if I'd stayed with the company, it might well have helped me move up
into
positions of more authority and better pay.)
My boss, on the other hand, tended to make schedules and then calculate
the
total labour costs  and then go back and redo her work until she
was in
better shape. I didn't have the same hitormiss approach, and
the work was
much easier for me. (I could go very slow and easy and still
look to the
uninitiated as if I were accomplishing huge amounts in tiny periods.)
I had particular luck with this stuff when tutoring a coworker in algebra.
It was clear to her that having mastered the material she was working
on made
a difference in the workplace. And since I was simultaneously
training her
on the paperwork for the home office (hoping to get her more hours),
we
looked at the formulae that we were supposed to use and tried to get
to the
point where, even if she couldn't remember them, she could reconstruct
them.
2. When you go to college (I'm not sure how this usually works in primary
and
secondary education), you will discover that a lot of your professors
will
grade "on a curve." Most students (or at least the ones I've
taught) seem to
believe that a curve means you get some number of points handed to
you "for
free" and added to your point score, which you can then convert to
a
lettergrade according to some easy algorithm. (This was a shock
to me, to
discover that they didn't have any idea how we were assigning grades
even on
"objective" tests where points were given or taken away for very specific
things.)
In fact, many professors will agree, up front, to assign a certain number
of
A's, a certain number of B's, and so on. So that in a 50 person
class, 5
people are going to get an A or better on the midterm, 10 additional
people
are going to get a B or better, 20 more people are going to get a
C or
better, and so on (or, depending on what the grades are supposed to
mean, the
pattern may be different). This helps professors adjust for the
fact that
what they think is easy isn't always going to be easy for the students,
and
that it's hard to write an exam that'll give you the score distribution
you
want. A score of 53 out of 100 doesn't mean anything at all,
then, until you
see the distribution of scores. I grew up with 64 and under being
an F, but
I've also handed out Bs to students with grades in the 50s, if the
test was
hard enough.
The problem is, if you're in a class with a lot of very talented people,
they're going to affect the curve. If there are 5 people in your
50person
class who are always going to be better than you on this material no
matter
how much you study and the professor gives no more and no fewer than
10% A's,
you're looking at a B.
Practically, this is something to consider if you have a handful of
talented
people in your programme. (It also raises questions about how
well,
especially in small classes with students who want to be there, the
curve
system works.)
Wholly aside from this, most professors will give you an Englishlanguage
statement about how they calculate grades on the syllabus. This
isn't
entirely algorithmic; if your quiz grades get steadily better
over the
semester, you're likely to do better than if your quiz grades get steadily
worse, even if you end up with the same total, and there's room for
judgment
calls (I once successfully argued to a professor that a student who
was very
involved, and very good, in a discussion section but whose exam scores
were
lower than I'd've expected, that "participation" ought to be weighed
especially heavily  that it was poor testtaking skills rather than
poor
mastery of the subject that was holding her back). But it's useful
to be
able to work out the formula.
Suppose your quiz grades are Q1, Q2, Q3, and Q4, your homework grades
are H1,
H2, H3, H4, H5, H6, H7, and H8, your midterm grade is M, your final
grade is
F, and your course grade is G (all on a 0100 points measure), then
knowing
that "The homework will count for 15% of your grade; the quizzes
and the
midterm will count for 25% each; and the final will count for
35%," you know
that the formula is roughly
G = ( (15*((H1+H2+H3+H4+H5+H6+H7+H8)/8)) + (25*((Q1+Q2+Q3+Q4)/4)) +
(25*M) +
(35*F) ) / 100
And you can calculate, going into the final, what score you need to
get the
grade you want  and you can also go lobby your professor to weigh
some
things more heavily than others ("I was really struggling at the start,
and
my first quiz and my first three homeworks show it  but if you look,
you'll
see that I had mastered that material by the midterm, and the second
half of
the course I did really well") if you look like you're near a cutoff.
I have known very few students who aren't interested in the precise
details
of how their grades are assigned.
Only fairly rarely have I been successful with "this material will teach
you
to think in a certain way," because people who don't have the skills
to think
in that particular way aren't usually aware of precisely what they're
missing, and they seem to think they've been doing just fine without
it.
(I'm having this problem right now, actually, with someone.)
My most
spectacular success was with a third grader who, having been told the
year
before that you couldn't divide odd numbers by two, reacted to his
teacher's
announcement that she was going to explain how to divide odd numbers
by two
(in other words, that she was going to introduce fractions) by becoming
very
distraught (this impressed me significantly more than it impressed
his
teacher or principal). The explanation that the ground rules
in mathematics
changed on a regular basis (the introduction of imaginary numbers so
that you
could find the square root of 1, for example) seemed to be useful
to him.
But he wasn't exactly typical.
On the other hand, demonstrating that thinking in the way I'm talking
about
can give me some insight into the kind of problems that students can
imagine
themselves encountering does appear to have an impact.
(Standardized tests can sometimes offer an answer to "Why should I learn
this?" but they don't motivate everybody.)
Another problem I've faced (and this is primarily in general philosophy
classes) is that some students who have always been successful in certain
academic areas suddenly fail  previous teachers may have expected
them to
master a body of knowledge and give it back on tests, but in philosophy
(which, like math, is primarily a skills class until a certain level)
we
expect critical assessment about the information they've acquired.
I've done
reasonably well starting out with, "It's really clear from this paper
that
you're someone who is used to much better grades than you're getting.
Let's
talk about what I'm looking for, that your previous teachers probably
didn't
ask of you." If I focus on the ways they have failed, they don't
come back.
If I focus on the academic strengths that are apparent (since I've
only
taught in the postsecondary environment, I'm used to students who
have had
at least some academic success in the past), I do better at nudging
them
toward the ways of thinking that I'm supposed to be imparting.
If you can track it down (I haven't had a copy for years), there's an
Isaac
Asimov story in the book "Nine Tomorrows" about a young person in a
society
where skills are essentially downloaded into brains who's shut out
of that
system. It's a story that's had a powerful impact on many of
the people I
know who think seriously about how they should be educated. Another
interesting book with a chunk about what we should study and how and
why (the
meeting with the academic advisor in particular) is Robert Heinlein's
"Space
Cadet". (This had a great impact on me at a time when I'd given
up on the
idea that classes were going to be accessible to me  I wasn't in
the public
system and thus not covered under IDEA  and that if I wanted an education
I
needed to figure out how to get it for myself, so perhaps I'm overstating.
On the other hand, I passed my tests okay even without having a clue
what
happened in the lectures, and I give at least some of that credit to
Heinlein.) I grant that you're unlikely to be assigning science
fiction in
the middle of a math class, but these are reasonably accessible items
that
I've found useful for places to start.
And, since most of my experience is with students who have chosen to
be in a
university, but are taking the class I'm working in to meet a requirement,
I've often started the semester with a "Why I think this is worth learning"
discussion.

Michael Chejlava <chejlavm@mail.lafayette.edu>
Here is an excerpt from a message that I sent to the Chemed list about
this
problem.
"There have been several comments about math and how it affects other
subject areas. Back in the dark ages when we still used slide
rules and
quill pens the math that was taught was mostly the "pure" math with
few
applications. Pure math is a selfcontained system starting with
a few
basic postulates and is then built up with theorems and proofs etc.
This
pure math can stand alone, but without applications it is just and
interesting mental game. I have gotten the sense that the math
community
is changing and starting to focus more upon applications.
The only caution I have to give you if you are a bibliophile like me,
is
that even with the low prices, you have to use some restraint."
Numeracy is what students really need. They need to understand
numbers and
what they can use them for. A basic understanding of statistics
would help
people to understand risks. A basic understanding of compound
interest
would keep many people from charging their credit cards to the limits.
The
ability to use proportional reasoning would point out that when a person
throws away "just one" aluminum can rather that recycling it they could
then calculate how much aluminum would be wasted if every person in
the
U.S. threw away "just one" aluminum can. If you cannot do this
calculation, then you are not really an educated person.
Unfortunately in most schools, the only place where numeracy is taught
is
in the chemistry and physics classes.
The current common method of having students memorize addition,
subtraction, multiplication and division tables at an early age with
little
understanding of what they are doing, or even worse, having them punch
numbers into calculators leads students to follow rote mechanical
procedures with little understanding of what they are doing.
In this
method they are also often taught that there is only one "right" way
to add
columns of numbers etc.
Somewhat better ways that I have read about are having students develop
their own addition tables by counting groups of items and then discovering
that it is faster to put together a table and memorize the results
of their
counting so that they can save time. Similar methods can be used
for the
other operations.
Another big cause for innumaracy is the fixed time, variable learning
method used in schools, where all students are passed along at the
same
rate. Eventually many students get behind enough that they simply
memorize
operations without understanding.
Schools should also add frequent diagnostic testing of each students
strengths and weaknesses, rather than just looking at total scores.
This
practice is what keeps the Sylvan and other commercial learning centers
in
business. Often a single misunderstanding by a student will show
up later
a failing grades.
I believe that ALL evaluation of student learning should be continuous,
diagnostic, AND comprehensive.

Chemical equations are the sentence of chemistry. Without an understanding
of chemical equations, stoichiometry, the mole, and the periodic table,
you
are not doing or learning chemistry, but rather a bunch of facts.
I have not diagrammed a sentence since I was in sixth grade. I
do not
remember all of the terms used in grammar, but I can write with correct
grammar, in most cases, and I can recognize when what I am reading

with grammar?
+++++++++++++++++++++++++++++++++++++++++++++++++++++++
"Theall, Michael" <Theall.Michael@uis.edu>
Michael,
I'll excerpt & respond, but I think the bottom line is that we basically
agree about what's really important.
"I agree that real world examples are important, but students needs
the
basic skills before they can do anything useful with any knowledge."
I never said not to teach basic skills, only to teach them in ways that
were
more successful for more students.
"Chemical equations are the sentence of chemistry. Without an
understanding
of chemical equations, stoichiometry, the mole, and the periodic table,
you
are not doing or learning chemistry, but rather a bunch of facts.
I have not diagrammed a sentence since I was in sixth grade. I
do not
remember all of the terms used in grammar, but I can write with correct
grammar, in most cases, and I can recognize when what I am reading
is
grammatical. Since I am not an English teacher, should I have
not bothered
with grammar?"
Again, I never said to ignore equations, but to put them in a more
understandable context. English (or whatever language) is everyone's
everyday mode for communication with everyone else. Thus everybody
needs to
be able to use it well. Only chemists talk to each other in equations.
"When I learned to play a trumpet, I was taught proper fingering and
embouchure. I played scales, did countless exercises and learned to
read
music. Since I never planned to be a professional musician, should
I have
just been given the instrument and be left to play with it and make
any
sound that I could get out of it?"
Again, I never proposed this kind of extreme approach or the abandonment
of
solid basics.
"Unfortunately environmental chemistry is tremendously complex.
It requires
an understanding of stoichiometry, kinetics, physical chemistry,
photochemistry, equilibrium calculations and many other topics far
outside
the realms of chemistry, including geology, meteorology, biology, economics
etc. To show a students a few massively simplified examples
and passing
it off as chemistry does them little good."
Sounds as if I hit the sanctity of content button. I didn't say
to
massively simplify anything and I used the term 'ecological' to mean
a more
comprehensive, systematic presentation that incorporated applications
and
integration. The same applies to statistics, for example, where
many
courses treat the material only as mathematics, and students never
get a
solid understanding of how and why the content works. For most,
it's not
the derivation of the formula so much as the application. I know,
understanding the derivation helps to understand how the application
works.
My objection is to skipping the integration and application altogether.
"Then why should all students be required to read Shakespeare, or Milton,
or
any of the "great masters" if they are not going to teach literature
and
all they need to do is to read a newspaper or job application?
Why should anyone ever need to know about the War of 1812? The
war is over
and we know the final score. I doubt that the conditions that
brought
about this war or the methods of fighting it will ever be of
much
practical use."
Social science and the humanities deal with human interactions that
are in
one way or another, a part of everyday life. People act, react,
and behave
in ways that can be illuminated by history and literature. On
a day to day
basis, the student who never gets anything except equations and the
periodic
table won't be able to see the connections of chemistry to daily life.
Even
then, our daily existence is characterized by multiple human interactions
that involve us more than the chemical content of our toothpaste.
Note that
I said "involve". This doesn't deny the importance of understanding
how we
are affected by science, but it does mean that the vast majority of
people
do not have to interact in the same way with math and science as they
do
with other people. To be expert in the methods of fighting in 1812
is not
pertinent to many, I agree. And in the same sense, to be expert
in
recalling the formula for acetone isn't very pertinent either.
"It does not take a genius level IQ to balance chemical equations.
In the
act of learning to balance chemical equations, the student should learn
that in chemical reactions that matter is not created or destroyed,
but
that the way the atoms are bonded is changed."
Never said it did & I agree with the underlying, important learning
you
note.
"I totally agree with the above two comments. However, teaching just
a few
"stories" about chemistry without some basic understanding is worse
than
useless, since the students would then think that they knew chemistry."
I never argued for just telling "a few stories", nor did I claim that
they
would suffice as learning.

This did catch my eye as, since the approach making music relevant to
the
student is part of the foundation of the Suzuki method (If I understand
it
correctly) Learning an instrument is far more likely to happen if the
student engages and music has real life relevance. In this case,
the skill
is learned by imitating parents and peers, weaving the skill (scales,
etc)
into a social fabric which gives it relevance for the child's life.
So, perhaps, yes, learning music organically might not be so bad.
As a
child's appreciation grows, I suspect the child would have have greater
motivation
to do scales.I'm curious, do you still play? If not, perhaps
'playing around'
might have not been so bad. Ofcourse, having more time would probably
help too, I'm sure!

The best answer I have ever seen...quote

Why study math?
Teachers of mathematics are bombarded with questions like this every
day, so I think one has to
know how to respond to it without the sort of made up "pain is good
for you/it will teach you how
to think/it's going to be on the test" crap.
Generally, I tell them the truth: except for arithmetic (including
fractions), some stuff involving per
cent, and some idea of ratio, you probably will not use any of this
for anything in your daily life.
And you can probably find some sort of workaround even for that.
So very little of it is of any
use at all for the average person.
Here are some of the responses I give when my students ask "What's this
good for/Why do I need
to know this?" None of them are absolutely convincing:
1. It's fun. Not the systematic, followtherulesandapplytheformula
sort of stuff, of course.
That's not much fun at all (there's pride in a job well done, yes,
but not much joy). Unfortunately,
the fun stuff usually requires you to know the systematic stuff "cold".
If you don't, you usually
don't even understand that the question is interesting (if you
even understand it!), let alone how to
get an answer. Just wait until you jump out of your seat and
knock over your friend's soda
because you just realized there was a lineandahalf proof of why
there are 63 games played in
the NCAA basketball tournament. You'll see.
2. It does teach you how to think. Not "logically", really, but
in three important ways:
a) It teaches you to go back and forth between the "big picture" and
the "details" (the forest and
the trees). Solving any mathematical problem that has more than
one or two steps usually requires
you to do that, and the more you do it, the better you get at it.
b) It teaches you to be careful. If you're not careful in mathematics,
you're the bug, not the
windshield.
c) It teaches you that if you can figure out the rules, and follow
the rules, you will get the answer,
just like magic. Even better, you will look "really smart", when
all you really did was follow the
rules. (I have personally been coasting on this for the better
part of three decades.)
Each of these three ways of thinking is extremely useful in everyday
life, whether you are a car
mechanic (like my father), a surgeon, or an Assistant Customer Service
Representative Associate.
Each is also absolutely unrelated to any particular problem or concept
in mathematics: it's a way of
thinking, not a piece of knowledge.
3. It depends on what you plan to do with your life. Tell me what
you plan to do for a living, and I
will try to tell you where you might use something. If you aspire
to be Chief Burrito Folder at
Taco Hut, you probably won't need any of this (well, maybe just a little
dynamical systems). But if
you want to do anything at all technical (business administration,
engineering, computer anything)
you will need lots of math. Will you need to know the pointslope form
for the equation of a line?
Maybe, maybe not. Tell me who you are going to take a course
from, or get a job with, five years
from now. I'll call her up and ask her, OK?
4. You don't actually need math for anything at all. Well, that's
assuming you are a God, or if not,
that you have a really excellent graphing calculator (with MIndRead?
interface to push the buttons
for you). Mathematics was invented because we aren't smart enough to
intuit the answer to every
question we might be interested in. And the dumber you are, the more
math you need. (And you
wondered how come I know so much....)

One answer that I give now is "because that is what our accreditation
board
requires". We are primarily an engineering school (which has
more obvious
reasons for requiring math), but I still get the question "Why do I
have to
learn Calculus, I have talked to every engineer on this planet and
not one of
them ever uses Calculus in their job, so why do I have to take it"
(that might
be a bit exaggerated).
I have used many methods to try to convince students that it is an important
part of their development.
A) I tell them that any natural science degree is really an applied
mathematics
degree, because that kind of degree requires a higher understanding
of math.
B) I tell them that Calculus is the base language of engineering and
science. I
then invite them to open an advanced engineering text or two and see
what kind
of symbols and notations they see.
C) I try to explain the difference between an Engineer/Scientist and
a
Technician. What are the expectations of the two positions?
How do they differ
in education and training (this is where the math comes it)?
How do they differ
in pay and mobility? I acknowledge that Engineers are sometimes
really
Technicians, and sometimes Technicians become Engineers, but the degree
is more
likely to affect pay and mobility.
D) my short response is "to get your degree", which does not satisfy
students
but is sometimes appropriate.

My take on question #1
Math is hard because we, the teachers, make it harder than it really
is.
For instance, students will say that math is about memorizing a bunch
of
formulas. No matter how much we argue against this perception, the
fact is
that most Math textbooks place a lot of emphasis on the formula.
Students
get the idea that regurgitating the formula is all they need.
In my experience teaching algebra, I only emphasized the axioms of the
real
numbers. I made sure the students understood that any other formula
was
just a shortcut to which they could get time and time again using the
axioms only. Using the formula was not required, solving the problem
was. When they could not remember formulas, I simply asked to
solve the
problem any way they could. More often than not, students can think
a valid
solution if they are given the chance; many times the student will
use the
formula correctly without "remembering it" that is, without regurgitating
the formula first and then plugging the data. If Math is about thinking,
our teaching must reflect that goal.
My take on question #2 is this:
How do students know they are NOT going to need this stuff?
A reverse example: I was the only Math major NOT to take the computer
science emphasis while I was in College. I did, however take the three
computer science courses that were required as part of my course work.
My
graduate work did use computers but did not specialized in computers.
Then
Life happened and I am making a living of the knowledge I acquired
about
something I did not consider "worthy" when I was in College. Yet, when
it
happened, I was ready to jump in the field, because I HAD to take those
courses. How many of us can relate to this story?
We could initiate a discussion in which the students define "useful"
or
"practical." We could explore specifically what is useful under
that
definition. We could "move back in time" and use that definition to
"discard" stuff that was deemed "useless" at the time (but that, of
course,
they can not live without these days). Examples abound. The moral is
to get
them to understand that the more prepared they are, the more doors
may open
in a future that they can not determine now.

That was great to hear. Willard Daggett's, a featured speaker
at the NADE
conference, questioned those same things. Other countries my
be passing us
up in teaching what is needed in the "real world" while the US is stuck
in
the "old academic world" which hasn't changed for generations. "Because
I
said so" doesn't work.

Though you have to admit that what got our civilization to where it
is currently
is the education system that was in place from the turn of the century
through
the 70's and maybe into the 80's. Change for the sake of change
is not
acceptable, and I believe that has happened over the two decades.
It seems to
me that it changed with the goal that more people pass math with higher
grades,
not that they became better at math. Consider that with a greater
dependance on
technology instead of learning how to think, we may be slowing our
future
progress, it may be difficult to recover from that trend.
Maybe when some of these changes were made the right questions were
not asked.
Instead of just asking how it would affect all students succeed in
math (or at
least think they succeeded), it should have been asked "How will this
affect our
future scientists, mathematicians, and engineers? Will they have
the necessary
background to do their jobs? Will they be able to take us to
the next level?
Are we preparing students well enough for math in college where many
of these
programs are still very traditional in their approach? I believe
those
questions were not considered, and every year our students seem less
prepared
and less willing to compensate for their weak math background.
