On the Impact of Dalan-E-Sabz Computer Game-Aided Instruction in Recall Increase of Chemistry Concepts of First Year High School

The problem of forgetting course subjects during the long Norouz holiday and summer vacation in Iran sits among one of the main teachers’ concerns. This article aimed at investigating the impact of a researcher-made game called Dalan-e-Sabz to recall basic chemistry concepts. The present applied study aimed at investigating the impact of Dalan-e-Sabz game to help recall basic chemistry concepts among the first year high school students in 2014. In this study، the experimental and control groups designed by removing a covariate effect were used. In fact، covariate scores were the same measured pretest scores before applying any treatment on learners. The samples in the study were three groups of 30 people (90 people) from a high school for boys in Koohrang City. Due to the long research process and reducing the subjects’ failure to zero، a convenience sampling was used. The data analysis was performed by SPSS with covariance (ANCOVA) analysis. Research findings revealed that Dalan-e-Sabz game and none-concept chemistry game، considering the covariate variable، showed to be significantly different. What can be concluded from the study is that this game had an important role in recalling the course subject، so it can be used for improving the learners’ free time.
