Undergraduates, while student teaching, often have little contact with their campus except for visits from their college supervisor. They have no convenient way of sharing their experiences with their peers, of asking a mathematics professor ahout a troublesome topic in subject matter, of becoming acquainted with alternatives in textbooks, supplementary materials, and teaching aids, or of becoming involved in the production or field testing of experimental materials. Some have never taken a mathematics-education course, and others do not realize the relevance of what they have studied to teaching mathematics until they begin to wrestle, with problems in teaching mathematics.
