Calculus in One Variable (Chinese) 1.0.0 COMPUTERS ARE ICUMEN IN Ralph P. Boas Department of Mathematics Northwestern University Evanston, IL 60201 There was a time when teachers Could just get up and talk. Slateboards were invented; You wrote on them with chalk. At least this slowed the lecture So the audience could try To take some notes on everything Before it passed them by. But slate was too expensive, So substitutes arose That scattered dust on everything But mostly on our clothes. (A kind that's best forgotten--- It died while it was new--- The yellow board with purple chalk That turned your fingers blue.) The overhead projector Seems to help, as well it may, As long as you can make enough Transparencies each day. But I have seen the future, And I don't like what I see: Computers in the classroom, They come too fast for me. There's lots and lots of labor, As far as I can hear, Creating complex programs To make simple topics clear. There might be an alternative We shouldn't overlook: What's wrong with telling students That they have to read the book?
