The findings of this study revealed that by using the T-Test according to the one sample T-Test, the pre-test average score was 42.5 while the post-test average score was 77.91. This means that the average difference between before and after the application of block jenga media is significantly different. The N-Gain test produces a value of 0.6238 for the N-Gain score, the mean, or the average value. The effectiveness value of beam jenga media is moderate because the deviation is less than 0.7. The mean or percent average N-Gain value at that time was 62.3810, or 62.3%. If the conspicuousness is between 55% and 75%, it can be said that the use of beam jenga media is quite effective.
