Student participation in such instructional activities as presentations, panel discussions, and projects can be used to stimulate interest and learning. Such activities need not be limited to a single class. This paper describes potential linkages between selected classes in which students from upper level or graduate classes are used as instructional resources in other classes. The general approach, which is described as a student-to-student program, has been applied in a Policy Fair. The Policy Fair is described and evaluated in this paper. There was widespread support among faculty, graduate students, and undergraduates for the general concept and this specific application.
