This research study explored the effects of the use of clicker technology as a means of formative assessment in large, college introductory psychology courses. Academic achievement, as measured by performance on tests of knowledge, was compared between students who used clickers and students that did not use clickers. There was a significant difference between the two groups, although a small effect was noted. Students using the clickers responded to survey items created to solicit information regarding student perceptions of increased understanding, ability to self-identify content deficits, fun, and financial value of clickers. Data from the survey indicated that the majority of students perceived the usage of clickers increased their understanding of and ability to self-identify concept areas. All of the students reported that using clickers was fun, although approximately only one third of those same students reported that purchasing a clicker was worthwhile. Implications for administrators are discussed and alternative technologies are explored.
