An electronic system has been developed by which individual multiple-choice responses from a large group of students can be recorded and analyzed for the teacher's information. The equipment includes individual sets of response buttons, computer processing of responses, and control unit for the instructor, and a control and display unit showing a percentage breakdown of responses in the projection booth. The system provides feedback to the instructor both in lecture assimilation and test administration. Computer processing provides a statistical analysis of responses to each question and aids in test formation and evaluation. Reactions are given from both instructors and students. (MM)
