Hi Jennifer:
Pretests: Great, good example of the type of class where pretesting can extremely valuable. One area that student performance varies a lot is with math related topics.
How nice to be able to know where more or less will be needed in a class thus minimizing wasted time on unneded material or misplaced emphasis. Of course, all objectives have to be met, but some topics can benefit with more emphasis while others can do okay with less.
Regards, Barry
