[net.followup] Schools requiring personal computers

jj (10/24/82)

	Yes, indeed, I agree with sdcarl!lin about students on work study.  
I staggered through 3 years of undergraduate school as a work-study student
with all my calculations done on a $5.00 plastic slide rule.  I habitually
got 90-95% on tests in which I knew exactly the answer in fractional form,
simply bacause I didn't have the time to solve to more than 3 digits.  I finally
bought a calculator  (4 banger) after my junior year when I had $66 left to
spend for the summer, and I used it to buy a calculator.  I borrowed money 
several  times the next year to buy batteries since I couldn't afford the
model with ni-cads. (AND- the first to laugh in my presence will find some
serious weaknesses in my sense of humor) I can't help but think that my 
unlamented alma mother (expletive) is going to wind up as a school for the rich 
and totally underpriveleged (who get one free), with not a single merely
poor person in the school.  While I do agree that the idea is indeed good
for engineering students to have to use computers, I think (and maybe CMU
is ahead of me) that the school that does so may have to buy the computer
for most of their students.  This would, however, represent a complete
turnaround at the financial aid office there, as they used to tell you
that a calculator was "not necessary".  Sometimes they would even ask
you if you had a calculator, and if you said "yes" tell  you that you
had too much money. 
	In short, while I think that requiring engineering students to
buy computers is not all that bad, the idea will have to be VERY carefully
executed to avoid locking out a great portion of the freshman class.  The
care and planning that were evident during most of my stay wouldn't encourage
me to have a lot of hope, although I was only part of the Cyert school for
one year.
	A question,--- what is an artist or a sculptor, of which there
are a lot at CMU, going to do with a computer (or have I  missed the 
qualifications for those required to buy one?).  
As an aside, when I went to CMU, the only computer available was an
ancient IBM360/67 that broke twice a week and couldn't
handle the load placed on it.  All those 10's and 20's you hear about were,
at that time (and may well still be, I'm not speaking to the place) only
for C-S grad students.

Don't mail me, I don't really care.  If the world might, write an article.

How bad this is depends on how vital the facilities offered by the
machine are in completing courses.  When I took first-year physics,
many moons ago, one feature of the first lecture was a statement
along the following lines:

	A good slide rule (not a six-inch toy) is an absolutely
	essential tool for this course.  If you do not own one,
	either buy one or drop this course.  You cannot possibly
	pass without one.

I can easily visualize courses where the same comment would apply
to a personal computer.  Naturally, I can also visualize courses
where this isn't the case, and in such cases a requirement for one
would be a bit more dubious.

A blanket requirement that a student own (or have access to) a
personal computer, regardless of detailed choice of courses, can
be justified only if:

	1. The cost is low enough that anyone who can afford a
	university education can afford the computer.

	2. The convenience offered by assuming that all students
	have computers is such that it is no longer worth aiming
	course materials etc. at people who don't.

It seems to me that #1 is pretty much satisfied already.  Especially
in the US.  It is easy to say "well, I paid for my own education, and
I couldn't have afforded a computer on top of it all".  Well, friends,
I paid for most of my own education, and I don't see how I could possibly
have managed it if I weren't north of a certain national border -- the
tuition fees at US universities are enough to send a Canadian student
into shock.  (Tuition up here is counted in hundreds, not thousands,
of dollars.)  I don't want to start an argument about financial limits
on the accessibility of education, which I agree are a problem.  I just
want to point out that anybody who has paid his own tuition in the US
has already solved far worse problems than finding the money for a
modest personal computer.

I'm not sure about #2.  I've used computer text-editing systems to the
near-total exclusion of other forms of text preparation for a number of
years.  I'm sure I started doing this rather earlier than most undergrads
at most universities, and I'm equally sure it gave me a non-trivial
advantage over a poor guy with a typewriter.  Given not just computers
but also decent networking, the advantage would get much stronger.
I vaguely remember a recent paper, in CACM I *think*, which discussed
the advantages of electronic mail in teacher-student and student-student
communications.  I can easily see these points and other considerations
putting non-computer students at an increasingly serious disadvantage.

Eventually there comes a time when access to the new tool becomes so
easy, and use of it becomes so important, that it is no longer worth
trying to cope with the special problems of students who *don't* have
access to it.  However, it's not obvious to me that this time has quite
come yet.  Especially at places where "computer communications" means
swapping floppies.  Ugh.  CMU may well be on the right track, although
I think they are trying to push things along rather hastily.  I'm not
at all sure about Drexel;  it is not clear to me that the standard
commercial personal computers are right for the job.  For students in
specialties where computation and graphics are important, they may be
useful enough to be justified, but otherwise it's not obvious to me.

It seems to me that the key issue is one that hasn't been raised
explicitly so far.  There is little doubt that access to a personal
computer (which in practice will often mean owning one) will shortly
have such compelling advantages that doing without will be foolish.
Shortly after that, these advantages will be taken for granted to the
point where the cost-effectiveness of teaching computerless people --
at least in the same classrooms as the rest -- will be doubtful.
The real question is not "whether" but "when".  Does anybody have any
thoughts on this?  Clearly one can set limits on it.  It's marginally
possible that now is the time -- but it ought to be obvious, and it's
not.  It is almost certain that when we have Alan Kay's Dynabooks in
volume production, the time will already have arrived.  What criteria
must be satisfied before we can say "now is the time"?

And just so I don't sign off without offending anybody...  For the
immediately-foreseeable future, it will be very hard to beat the cost-
effectiveness of a keyboard for serious man->computer communication.
Ok, probably you want a mouse and some other minor amenities as
well, but for text manipulation (possibly the single most important
use of personal computers), keyboards just cannot be beat.  Voice-input
technology is primitive, and even if all the technical problems were
solved it would still have serious warts.  Note that I distinguish
between casual use of computer facilities by Joe Public and serious
use by students and such, and am discussing the latter.  Electronic
"telepathy" is probable in the long run but unlikely to arrive tomorrow.
Handwriting recognition cannot compare on speed, ease, and accuracy.
Keyboards are it.  Now, it is not terribly hard to learn to touch-type.
Speed comes only with practice, but working with these bloody machines
will give you lots of that.  So...

	Resolved:  the ability to touch-type should be an absolute
	prerequisite for all senior Computer Science courses, and
	should (given the increasing importance of computers) be
	seriously considered as a prerequisite for *all* science
	courses.

You wouldn't expect to be able to pass English without being able
to read well;  why should you expect to pass Computer Science without
being able to type well?

	Instead of a lot of flaming about What CMU will do.  Or how the
student's feel.  I suggest anyone interested in this topic get a copy
of another information medium: Newsweek.  This week's article on
Education is:  "The Computerization of CMU" P91 Nov 1,1982 issue.

	Surely, with the technology changing so fast, schools cannot expect
to require the PURCHASE of a piece of obsolescnt equipment without a guarantee
that the equipment will be of use throughout the course of study.  (naturally,
the answer to this question is: Yes!).  )(*&%^$%$%$%!!!  It seems that the
microsystem revolution has now reached the ridiculous.  I wonder if it
will every reach the sublime???
