On Improving the Exehange of Information between Students and Teacher

Several systems exist for the purpose of assisting the instructor in evaluating class comprehension by monitoring their individual and/or collective responses to multiple-choice questions. Such a system, the Student-Teacher Interface System (STIS), is described and its capabilities are compared with those of other systems. The STIS is a special-purpose digital processor which provides a considerable amount of real-time display information to both the instructor and class. Sotne of the benefits associated with such a system are discussed and the students' opinions of the class feedback displays are presented. With the use of MSI integrated citcuits it is estimated that the instructor console could be built for under $500.
