The researcher found that The average score for the experimental class was 59.57 for the pre-test and 71.277 for the post-test. While the average score for the control class was 51.60 for the pre-test and 54.255 for the post-test. The obtained t-test was 11.835 whereas the t-table was 1.980 for α = 5%.
