Assignment:
I have had great success teaching math using computers. I find that you can track the progress of each student using individual pass codes to see how well they are mastering each concept. Many programs and dvds have a data collection resource, and each student should have a one to one time with the instructor regardless of whether they are having trouble with concepts or not.
Students seem to understand concepts better when they are allowed to work silently and anonymously. Students who are highly skilled can keep other students with math troubles from speaking out. This method protects the privacy of those who really need individual help without the humiliation of peers knowing where fellow students are not excelling well.
