- A big one in the 60s was "programmed learning." The idea was that a
- programmed text, or even better a computer program, could interact with
- an individual to teach the subject. Now I suspect that a good program
- of this type could be made up for mechanics, such as routine arithmetic,
- or calculus computations, or possibly even for rote learning of disease
- symptoms. But it will be routine. Even for testing the formulation of
- word problems, a computer program could only recognize if the formulated
- problem had the correct solution, but not if the formulation was correct,
- but other than one of the expected ones.
-
- But technology can be used intelligently. If we had elementary teachers
- who understood the structure of the number system enough to answer questions,
- we could give them taped lectures, to be stopped when questions arose. Also,
- the teachers would have to answer other types of questions. This was
- considered for lecture-recitation courses, but the saving of a lecturer
- or so did not compensate for doubling the number of recitation instructors.
-
- Another thing which I think would be a good idea is video classes, essentially
- handled like video conferences, not like lectures. This would greatly
- facilitate giving "special" courses to students in different locations,
- and could even be used to handle the problems of discipline, danger to
- teachers, etc. There are those who deride calculators; but it is more
- important to teach Johnny WNEN to add than HOW to add. Calculators and
- computers have made much of what is now emphasized almost irrelevant.
-
- But without competent teachers, not much can be done. At the present time,
- I see no quick (< 10 years) method of getting enough competent teachers.
