[ut.general] PhDs vs. teaching

henry@utzoo.uucp (Henry Spencer) (03/17/89)

A week or two ago I posted an article about PhDs and teaching and so on.
I've just been slightly horrified by the realization that it could have
been taken two different ways.  "PhDs are all lousy teachers and we'd be
better off replacing them with undergrads" is *not* what I meant to say!
Now that all my faculty friends are now ex-friends :-), I'd like to
clarify what I meant.

The intent was to point out that possession of a PhD does not always
imply strong teaching ability, that teaching ability is more important
than PhD-level technical background for teaching first-year courses, and
that it would seem possible to make more effective use of available
manpower.  Sorry if anyone was offended; it wasn't deliberate.

I don't know which is "more important", but at least in Physics I
think a PhD-level technical background is extremely important in
teaching first-year courses.  Typically, an undergraduate Physics
specialist learns the subject in a very compartmentalised way:
mechanics, E&M, statistical Physics, etc.  An integration of the
knowledge occurs at the graduate-student level for most (although
some able students achieve it as undergraduates); by "integration"
I mean realising that the thematic and mathematical content of the
different sub-fields is essentially similar.  Before that realisation
I think it unlikely that the person will be capable of effectively
teaching at the first-year level, although (s)he may be quite good
and second, third, or fourth year courses.

I *am* implying above that teaching at the first-year level is more
difficult than any other.

Also, Physics changes fairly rapidly and without a PhD-level background,
10 years down the road that person is going to find it quite difficult to 
understand those changes in a sufficiently deep manner to teach them
effectively to first-year students.

None of the above is meant to argue that a particularly able person
without a Ph-D cannot be a spectacular first-year pedagogue.  But
I believe that my PhD training has been extremely helpful in teaching
at the first-year level, and think that for most people, similarly
not particularly able, this would also be true.

A recent .signature from another person stated: "Those who do not
understand Henry Spencer are doomed to re-invent DOS", or words to
that effect.  Does that mean that U of T is now "Microsoft North"?

Okay, we'll have the PhDs teach the first-year courses, and hire
undergrads to teach the other years! :-) :-)

More seriously, although I wasn't aware of this situation in physics,
note that my original posting specifically suggested hiring the *best*
final-year undergrads as first-year teachers, not just any random bunch.
The selection process would not be trivial, but I think it could be done.
