Data were collected by observation and documentation. The data on the effectiveness of learning media were analyzed with gain, normality, t-test at a significance level of 0.05. The results of the comparative study of class IX F at the first meeting the average acquisition is 83, the second meeting the average acquisition is 85, the third meeting the average acquisition is 87, the fourth meeting the average acquisition is 90. In class IX G meeting 1 the average acquisition 84.2 , meeting 2 an average of 85.5 , meeting 3 an average of 87.7 , meeting 4 an average of 90.5 . Based on the calculation of N-gain, obtained an increase in the results of the pre-test and post-test of class IX F of 0.67 in the medium category.
