Siko, J. P., Barbour, M. K., & Toker, S. (2010, October). Homemade PowerPoint games in a high school science setting. A paper presented at the annual convention of the Association for Educational Communication and Technology, Anaheim, CA. This study examined the use of homemade PowerPoint games in a secondary environmental chemistry classroom, comparing the performance on two unit tests between a control group and a group that created PowerPoints games. Results were mixed; with no significant difference in performance on one unit test and students who designed the games performed significantly better on the other unit test. There was also an increase effect for students who created games for both tests.
