I would like to make a few comments. Our educational indices are very poor measures, but they are the best we have. Our teaching methods have changed in the past 50 years, mostly for the worst, but our examination methods have become absolutely atrocious. The important parts of the courses are almost totally ignored in evaluating the students! Before the social adjustment (put your favorite pejorative here) gurus got into the school systems about 50 years ago, even elementary school courses had content. Children were expected to learn about X in course Y, and in later course Z, they were expected to be able to use their knowledge of X. This was even the case if X was badly taught; the even fairly good elementary texts do a better job of teaching the use of variables than the high school books then or now. Even though it was very badly taught then, junior high students were tested on the ability to solve word problems. The ones who could not do it were effectively eliminated from taking subsequent mathematics, so those teaching high school mathematics were not concerned with students who could not do this type of abstraction. I have no objection to teaching those who cannot figure for themselves the use of symbols that use. In fact, I think it should be done no later than the third grade. But I would expect students to be reasonably adept in using symbols as language in subsequent presentations. I do not think that 25% of the present high school teachers of mathematics are capable of this. The testing methods of >50 years ago with the slight improvements in teaching methods since, properly applied by reasonable teachers, can do the job even with large classes, provided we consider the level of the course not adjustable to the level of the students. It would take at least a 20 year program to get enough qualified teachers. If we now raise all teachers' salaries, this will perpetuate control by the baby sitters. We also have to recognize that different children should proceed at different rates, and we may need different teaching methods for the same subject. The use of television classes (not lectures) may make things possible. Teachers should also be talent scouts and recognize that they are quite capable of destroying thinking ability. -- Herman Rubin, Dept. of Statistics, Purdue Univ., West Lafayette IN47907 Phone: (317)494-6054 hrubin@l.cc.purdue.edu (ARPA or UUCP) or hrubin@purccvm.bitnet
