Post by Dr A. N. Walkerlots of people who can churn out maths without ever really understanding
what they are doing
Could you explain this further, please?
People who can apply formulas, reproduce bookwork, solve set
questions as long as they are essentially identical to ones worked
in class, but who do not know when the formula should or should not
be used, are incapable of producing bookwork that is a minor variant
on lecture notes, and have not the foggiest idea how to set about
solving problems that are new.
In the days when we *did* interview applicants, we would set
them maths problems which were deliberately not "A level" but were
designed to get the student thinking about some new situation. The
occasional genius just solved the new problem [these were not *hard*
problems]. Most tried a few things, got stuck, and then we tried to
steer them towards a solution. But quite a lot just put their pens
down, "no, we haven't done that". "I know, I want to see what you
make of an unseen problem." "But we haven't been told how to do
this." "OK, what does this problem remind you of?" "We haven't
been told ...."
Post by Dr A. N. WalkerPost by Dr A. N. WalkerWhat is one supposed to do in maths with the person who simply
cannot follow a logical argument? [...]
Patience, repetition and a different approach?
We are dealing with education, not dog training.
Post by Dr A. N. WalkerPost by Dr A. N. WalkerThere is an innate *in*ability -- innumeracy, illogicality,
desperate need for the concrete -- that most of the population has.
This is an English problem, perhaps, as I do not find such pride of
mathematical ignorance to be prevalent elsewhere so much.
*Pride* in ignorance may well be an English problem. But
innumeracy is, apparently, the natural state, and those who can
transcend it are unusual and lucky. I don't think we should be
surprised by this. Ever since we have had civilisation, we have
had, for example, "amazing" language skills. We can still read,
eg, the Iliad today, and no-one has to say "well, for the period
it's remarkable, but of course Homer didn't understand how to
add love interest, or how metaphors can work, or ...". Likewise
a hundred great novels, poems, histories, even plays of ancient
times. A modern reader may need some explanation of conventions
or assumed background, and almost certainly needs a translation,
but otherwise these works are not very different from their modern
equivalents.
By contrast, in maths, indeed in the whole of science and
technology, there is just one ancient work which still [just about]
stands up: Euclid's "Elements". Ironically, that sort of geometry
is so out of fashion that scarcely anyone still does it, even as a
postgrad. Almost everything else in maths is "recent". Euler, in
the mid-18thC, is the earliest mathematician who could have been
handed an A-level exam paper [translated into Latin ...] and made
any sense at all of any of it. If it took two thousand years from
Pythagoras for us to get started in algebra, and several hundred
more for us to get to calculus, complex numbers, etc., no wonder
that most people "don't get it". We expect undergraduates these
days to understand things that flummoxed Newton and Galileo.
