Computers in school

Nicely said sir. 

The guy who started the Macintosh is still around and he sees more than
mice and windows. In fact I heartily recommend reading his recent book,
The Humane Interface by Jef Raskin. (I am, myself, quoted on page 18.)

Then too, there is the guy who wrote Engines for Education. I'll have his 
name shortly. He runs the Institute for the Learning Sciences out of
Northwestern University in Illinois. Roger Schank.

One of his associates developed Sickle Cell Counsellor as a rich learning
environment. It's on permanent exhibit at the SF Exploratorium and again,
I highly recommend trying it out. The folks there were astonished by the
length of time it captured folks. Instead of the usual one minute, more or
less, it captures visitors for half an hour or more. I tried it out and 
now know a lot about the subject despite my experience being years old.

Another school use of computers is as a *minor* tool. That is, the culture
and the educational goals are far more relevant than the details of the
supporting computer software. CSILE, the computer supported intentional
learning environment, is one such tool. It lets students build a hyper-
text (including drawings) of questions, answers, and other comments about
whatever subject is under study.

Naturally, that reminds me of IBIS and QuestMap which would add structure
and order to a hyper-text such as CSILE encourages. QuestMap is another
*minor* tool which is quite neutral to the content of the questions,
answers, and pro and con arguments input to it. Nevertheless, by the
structure it imposes, it makes obvious that a question can be reframed or
posed alternatively; that another answer can be proposed; that a new
argument can be added for or against any answer/idea.

I guess my general claim is that computers should best be used in the
classroom, not even as a tool, but rather as a medium. Like paper or
film or audio tape. We don't go to the theatre to watch the projector,
but rather what it projects and the sound it plays. Still, there are
limitless opportunities for schooling to be improved, and students to be
placed more centrally in the process, which involve computers in some way.
