Interactive response systems "clickers" can provide multiple benefits to the students and faculty who use them, including immediate performance feedback and greater student engagement in learning. My own exploration of this technology has yielded five pedagogically different types of polling questions, specifically measurement of student confidence levels, their comfort levels with various topics, assessment of attitude change due to class discussions, retention of course information, and basic mastery of course content. The present investigation revealed that students acknowledge the possible benefits to the instructor of using these polling questions, yet they were most appreciative of the opportunity to see sample quiz questions. More surprising, these students were unaware of the price of "clickers," despite having purchased them at the start of the semester, suggesting that use of this technology does not constitute a financial hardship for many students.
