This study examined three methods of responding to in-class multiple-choice concept questions in an Introduction to Psychology course. Specifically, this study compared exam performance and student reactions using three methods of responding to concept questions: (a) a technology-based network system, (b) hand-held flashcards, and (c) hand raising. All students had positive reactions to the use of concept questions, but students using the technology-based system had the most positive reactions. However, type of response method was not related to exam performance. (Contains 1 table.)
