clickers offer one approach to employing active learning in the classroom. They are more formally denoted as student response systems (SRS), audience response systems (ARS), or personal response systems (PRS).

Clickers help instructors actively engage students during the entire class period, gauge their level of understanding of the material being presented, and provide prompt feedback to student questions.

With clickers, students have an input device that lets them express their views in complete anonymity, and the cumulative view of the class appears on a public screen

In a normal class discussion situation, only one or two students have the opportunity to answer a question

Despite the lack of statistically significant results in this study, the perception survey data show that students perceive value in the use of clickers and would recommend their use in future classes. Contrary to expectations, learning outcomes of students using clickers did not improve more than the traditional active learning approach of using class discussion. Perhaps the value of the active learning pedagogy outshadowed the benefit of using clickers.

Sharing questions between instructors, or even providing a library or model curriculum of predesigned question sets, can make a big difference to a new instructor trying to climb a steep learning curve
