Student Feedback and Participation in medium to large classes: Using the Personal Response System. Do you want to get student feedback and participation in your classroom, but your class is too large for a discussion or traditional small group work? The Personal Response System allows instructors to ask questions during class, engage the students individually or in small groups, and receive immediate student responses that are automatically processed, tabulated and displayed graphically in class. Faculty luncheon workshop with CTL Associate Director Marcelo Clerici-Arias.
