Abstract
The authors conducted experiments in history classes in a technical high-school using the MMORPG "Uncharted Waters Online" and researched the educational effects. 291students (aged15-18yrs) were divided into control and experimental groups and their responses to the Pre- and Post- questionnaires were compared statistically. In Study 1, students who played the game fre ely (experimental group 1) scored higher than those who did not play the game (control group) in the scale of interest in history. Students who played the game following the teacher's instructions ( experimental group 2) showed improvement in their academic performance in the term examination immediately following the experiment. In Study 2, the quantity of communication among students and teachers in the experiment was manipulated and its positive effects were observed in the scale of interest in history. Lastly, the limitations as wel l as future potential of these results are discus sed.
