The Study of the effect of Coin79 game on the academic achievement of 10 th grade high school students’ chemistry

The purpose of this study was to evaluate the effect of educational mobile game based on theories of learning and educational psychology for the subject of the periodic table and also the effect of this method on students' academic achievements in the tenth grade of high school chemistry. The population of this study included all female students in the field of mathematics and experimental science in the tenth grade of high school who studied in Shahed and Fath Al-Mubin high schools in the city of Rey in the academic year of 2016-2017. Multi-stage cluster sampling method was used to select the sample. There were two groups of mathematics and experimental science in each of these schools. 20 students from the experimental school were randomly selected. They were presented and Q&A sessions were conducted online for the other group. In this study, finally, 20 people were randomly selected from the experimental group and 19 people from the control group due to the fall of the subject. Both groups were tested in ten sessions. After ten sessions, post-test was taken from the students again and at the end, the results were explained using statistical methods, analysis of covariance and block variance and the results showed that educational games (coin79) were effective on academic achievements. However, the effect of educational background on academic achievements was greater than the educational game and this indicated the condition that the educational game is more suitable for students with better educational background.
