Issues Raisedby Computer-Assisted Instruction
The current operational use of computer-assisted instruction in
many schools in this country, use that is well exemplified by the
a
detailed discussionof Alioto and Thornton, raises number of issues
a
I would now like to turn.
of a broad educational and social kind to which
I will discuss four rather closely related issues that have had
a certain
prominence in the discussion computer-assisted instruction (CAI):
of
1) individualization of instruction, 2) standardization of instruction,
3) complexity of instruction, and4 ) freedom ín education.
Individualization of Instruction
The first issue centers around the claim that the deep use

of impersonalized teaching. Perhaps the best ímage this issue in h e

To those of
advancing this claim deep impersonalization, ít is
important to say that indeed this is possibility, Computer technology

is little different from saying that there are many teaching

important potentialsís exactly the opposite. Computers can make

will be subject to less regimentation and lockstepping, because computer
systems will be able to offer highly individualized instruction.
It is important that the remark about individualized instruction
not be passed in
off as sloganeering. For many years,courses the
methodology of teaching have emphasized the importanceteaching
of

individualization ís extraordinarily difficult to achieve when the

ratio of students to teachers is approximately 1.
One direct approach is to reduce this ratio to something or

10 to 1, but the economics this approach is totally unfeasible in

All
the long run and on a widespread basis. the evidence points to
the fact that the cost having first-rate teachers in the classroom,
of
training these teachers appropriately, and providing them with the kind
of salaries that will be competitive with other technical and
for
professional jobs in our society will simply make it impossible
schools to afford any drastic reduction in the student-teacher
ratio.
One of the few real opportunities for offering individualized

instruction lies in the use computers as instructional devices.

of
computer terminals. While classes or substantial parts classes were
working at terminals, teachers would be able to work with the remainder.
Moreover, they would be able to work intensely with individual
students, partly because some the students would be at the terminals,

- Extensive results of
many efforts in computer-assisted instruction at the university level
at Stanford are reported in Suppes
(3.981).
Standardization of Instruction
A second common claim is that the widespread use of computer
technology w i l l lead to excessive standardization education. This

In the early days programmed instruction, for example,
a
number of texts on elementary mathematics were written by
psychologists or educators who did not have adequate training in

The world is full of textbooks that are obviously many

that are full mathematical
of mistakes; there areo elementary

books that are mathematically correct, but pedagogically bad beyond

The Use of Knowledge
To have an effective computer-based systeminstruction,
of we
must transcend mindless talking and listening and learn to understand
and use a large knowledge base.For example, ifwe were simply to
require information retrieval from a knowledge base, it would be
relatively simple in the near future to put the entire American
Library of Congress in every elementary school, The capacity to store
so
information is increasing rapidly thatwe willbe able to store
much more information than could ever possibly be used.
A different and more difficult ris how to get the student

A s we come to understand
to interact with the sizable knowledge base,
how to handle such a knowledge base, the school of the future

It
think, be wonderful to see how children interact with such a system;

we will see children give to learning the high degree
