This study employed a rank-based nonparametric test to examine the effectiveness
of a Classroom Response System (also known as a “clicker”) on attendance. A Mann-Whitney
U test revealed that attendance in the clicker class (experimental group) and attendance
in the nonclicker class (control group) did not differ significantly. However, a survey
of 28 participants in the clicker class showed that learners had positive perceptions of
clickers. Two focused group sessions in the clicker class also revealed that learners
enjoyed using clickers and that they found the clicker technology engaging, interactive,
and entertaining.
