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.
