This is the old "there's only one right way to do 'X'"
syndrome. There is some legitimacy to it, but I find
that it is taken to the logically absurd extreme, most
often to the detriment of the student. Some of it
seems to be because the concepts are difficult to convey
and let's face it, there are a lot of lazy people who
just don't want to take the time and make the effort to
find an analog that will cause a student's light to go
on and say "OH... I GET IT!" I also believe that kids are
somewhat tacitly taught to be afraid of math from an
early age. It's an expectation built into our culture that
says math is hard and only brainiacs REALLY get it. Great
way to set kids up for success, eh?
A big problem in colleges is that the many of the brilliant
mathematicians cannot teach to save their lives. They are
absolultely horrible at it. They vomit out theorems and
forms and if the student doesn't get it, tough rocks. They
need to be locked away in their closets to theorize and
discover new and wonderful constructs and methods and leave
the teaching to those that are trained to effectively convey
what is in their books and heads into the heads of the students.

They are narrow minded idiots and ought not be allowed
anywhere near a classroom full of students.

I took a topology class at UC Davis. It bent my brain just
as badly as my studies in particle physics. Those disciplines
are the lairs of the insane. Fabulous constructs, but so
oblique in some ways that my understanding stopped abruptly
once I grasped the generalities. Solving specific problems
was just this side of impossible for me. Needless to say I
didn't belong.

He was the profound genius that Edison could never have been.
Edison's one virtue was his stick-to-it-iveness. I will give
him credit as due, but otherwise he was less than shit as a
human being. A thief, a bully, and murdering bastard, but
let me not go on. :)

She was a lousy teacher. I had my share. One of the most
indescribably idiotic things I ever heard about was the
policy of the math department at Steven's Tech in NJ. Stevens
is one of the top engineering schools on the planet. They
have designed every 11.5 meter America's Cup yacht for at least
the past 100 years. The policy of their math department, at
least as of about 15 years ago, was that 25% of EVERY first
semester calculus class HAD TO BE FAILED, even if every student
got 100% on every test. When I asked why this was so, I was
told to the effect that the policy was intended to maintain
the school's image of being "tough". One can only wonder how
many young and otherwise bright futures were wrecked by such
imbecilic reasoning. What a terrible thing to do to young people
just starting out. If anything, I believe you start out easier
and get progressively tougher as one progresses through the
divisions.

That's pretty sad.
