Yes, but we should question closely whether it was the place or
the
teacher that "turns them out". Cambridge (both of them) attracts
and
accepts the brightest--it is not surprising, if they can do a
reasonable
job of admissions, that they turn out the best. Brilliance in,
brilliance
out!

Whether the *teaching* makes any difference is totally unknown, so
far as I
can see. For all we know, being there and spending time with the
other
brightest students in the country, perhaps the world, may
compensate for
the negative effects of the teaching! The same may hold for
Gottingen and
Heidelberg in their prime, as for Padua in the sixteenth century.

As a side comment, there is a debate in this country on 'What is a
good teacher?' and how to use criteria to relate to salary
increments. One Politically right wing term is 'value added'. How
to judge this with a teacher and use it to reward good teachers and
weed out the not so good.

The issue is fraught with peril. A comment from a 22 year old
trainee
teacher to me about a collegue of mine in another time and another
place.
"I learned more in (person X's) classroom, since he was away so much
dealing with (extra-curricular activity) that we had to get on and
learn on our own. I really learned how to study"
This interpreted ment 'I got the past papers, got the study notes and
did what I had to do to pass'

Here they now produce league tables of schools pass rates and means
in public exams.
Private schools are then compared to public schools in a lower
soioeconomic part of town (and there are numerical indicators to
determine this) quite uncritically by the public.

'Brilliance' in research is a different issue to success in exams as
well.

Derek--

I agree completely on both issues! I think it is extremely difficult
to
measure "value added" in teaching, because you have to measure value
before
and after, and you have to have some agreed on measure of value!!!

I once gave the same test to my Freshmen and to my Seniors with identical
results except the Seniors were sloppier. I said to myself, " I guess
the V. A. at this school is negative."
***************************************************************
But
even though it is fraught with peril, we need to address it because it
is
of immediate relevance to the rewards for teachers and, longer term,
for
the possibility of improving teaching.

I should confess that, as a philosopher at a university, my interest
is
very real but it has no practical consequences for me. But I would
like to
aid and abet the concerned secondary science teachers.

As to brilliance, at Rice we only admit highly qualified students, but
there is a fairly clear bimodal distribution. Most are quite able,
have
good study habits, do the homework, take tests well, get good grades.
A
smaller number are "different", often have poor study habits, don't do
the
homeowrk because it is boring, raise objections to test questions, and
often get mediocre grades. Most of them will never produce anything
of
consequence because of their poor work habits, disorganization,
indifference to social consequences, etc.

I doubt seriously that life achievement will be correlated.

But I think that the really
ORIGINAL contributions, if any, will come from a small subset of this
minority.*****Whoops, you are a little ahead of me. I agree. I go to
seminars at Rice and am on the philosophy dept. mailing list. Perhaps we
can meet?
