Large lectures continue to challenge teaching and learning. Our plant propagation course attracts a large number of non-majors seeking to fulfill their science requirement. Although the laboratory is quite successful in maintaining interest, the lecture is plagued by poor attendance and lack of commitment. To deal with these issues, I have incorporated an audience response system (as used in America's Funniest Home Videos) and a multiple-choice exam that uses a scratch-off answer system similar to the instant-win lottery tickets. The audience response system facilitates attendance, and both systems provide immediate feedback to questions. Student and faculty assessment will be presented. Technological and pedagogical challenges will be discussed.
