There are 32 students on each class. The pre-test was given to the students before they got any treatments. According to the Table 4.1 above, it can be seen that the lowest score in the experimental class was 38 and the lowest score in the controlled class was 28. However, the highest score in both experimental class and in the controlled class was same, that was 93. The mean score of pre-test in the controlled class was higher than the mean of pre-test in the experimental class. The mean of pre-test in the controlled class was 70.03 and the mean of pre-test score in the experimental class was 65.22.

The post-test was given to the students after they got treatments on reading narrative text. Each class had different treatments in order to increase their reading score on narrative text. According to the Table 4.2, it can be seen that the lowest score of post-test in the experimental class was 48 and the lowest score of post-test in the controlled class was 33. Then, the highest score of post- test in the experimental class was 95 and the highest score of post-test in the controlled class was 93. The mean score of post-test in the controlled class was higher than the mean of post-test in the experimental class. The mean of post-test in the controlled class was 74.19 and the mean of pre-test score in the experimental class was 71.41.
