Abstract In this study, the effects of the digital games on high school students’ academic achievement, motivation and retention in algorithms course were investigated. For this purpose, a computer game for algorithm development was used. Pretest-posttest experimental design with the control group was used in the research. Both groups took instruction for two weeks and experimental group students played the digital game during the same period of time, additionally. Participants took achievement pretest and posttest, motivation scale and retention test. There was no significant difference found for achievement and retention, however experimental group’s motivation was significantly higher than the control. Although the digital game did not make any significant difference on achievement and retention for the short-term application, it was seen that students were better motivated with it to develop algorithm.
