The mean score of post-test (91.3) in experimental class was greater than the mean score of post-test (71.6) in controlled class. The standard deviation of post-test (11.37) in experimental class was smaller than the standard deviation of post-test in controlled class (15.7). From t-test, the researcher found that the value of t-test (4.52) was greater than t-table (2.021) at the level of significance
