have you looked at the cost of math texts lately?

i worked on a mathematics teaching expert system under a grant from the national science foundation... interactive homework helps students grasp concepts much much faster, not by telling them how to do things right, but by understanding how and why the student did things wrong, and conveying that knowledge on to them.

for example, the most basic arithmetic assignment might ask a student "what is 2 * 4?"... if the student answered, "6" it's pretty obvious they are getting the "+" and "*" symbols confused.
