Today's students, with their exposure to a great variety of media, tend to prefer a learning experience characterized by: (1) considerable variety in learning methods; (2) a choice among alternatives as well as some feedback; and (3) quick-moving, active involvement that requires only a short span of concentration. A library science course in principles of materials selection was designed to fulfill these three learning requirements. The method used was an adaptation of the American Society for Information Science 1975 poster sessions; it consisted of a number of simultaneous informal student presentations using graphs, diagrams, data, pictures, and a small amount of text. The class was divided into teams that took turns making presentations and being active participants. In informal evaluations the participants indicated that there was more active learning taking place in this interactive, informal atmosphere than in traditional lecture textbook courses. An additional advantage was seen in the students' opportunity to use and improve communication skills they would need when working in libraries. (LS)
