The population in this study were all class VIII students consisting of 4 (four) classes. The sampling technique uses cluster random sampling technique. The sample in this study was 42 students from class VIII C as the control class and 41 students from class VIII D as the experimental class. The research instrument uses tests.

Apart from that, the average N-Gain value for the experimental class is 0.57 and the average N-Gain value for the control class is 0.50. The difference in increase from pretest to posttest for the experimental class was 44, while for the control class it was 28.61. Further test results based on the t test using paired samples test show a significant value of 0.000 < 0.05, so it can be seen that H0 is rejected and H1 is accepted.]]>
