- discusses his views on teaching economics in the context of his textbook
- and classes. I have not been teaching principles in recent years, but I am
- interested in teaching micro, both as a teacher (although only occasionally
- of late, since I am currently at a law school) and textbook author, so I
- thought I would put in a few comments.
-
- One of the problems in teaching economics is that the students think they
- already know it. The subject is all around them, and many of our technical
- terms are words, such as "efficiency," whose meaning they think they know.
- So a student goes along for a month "translating" the logical structure he
- is being taught into a much fuzzier form along the lines of what he already
- knows and only discovers that he is missing something when he fails the
- midterm.
-
- One solution to this I like is to get strongly counterintuitive results.
- When you reach a conclusion the student knows is wrong (one of my favorites
- is the argument showing that legalized polygeny benefits women but not
- necessarily men, and vice versa for legalized polyandry) he suddenly has to
- pay attention.
-
- So far as computer programs, I think it is possible to do much more than
- automated testing. I have a collection of three programs that go with my
- text (all of which I wrote). In one, which is designed to help students
- intuit the calculus concepts that they forgot from the previous year's math
- course, the student draws either TC, MC, or AC freehand on the screen (with
- a mouse), while the computer draws in one or both of the others. That way
- the student can play around with the curve, trying to how the curves are
- related. In another you have a MacDraw like environment for doing budget
- line indifference curve diagrams. My original idea is that if a student
- encounters indifference curves as a picture in a book showing 3 of them, he
- will assume there is nothing in between. If he encounters them as "click
- anywhere, the program draws the indifference curve through that point" he
- is more likely to get the intuition that they are dense.
