Based on table 4.2, it can be seen that 67 was the lowest students’ post-test
score in experimental class and 89 was the highest students’ post-test score in
experimental class while 60 was the lowest students’ post-test score in controlled
class and 83 was the highest students’ post-test score in controlled class. In addition,
2419 was the total students’ score of pos-test in experimental class and 2213 was the
total stud ents’ score of post-test in controlled class. The experimental class has the
average score 80.63 and the controlled class has the average score 73.76.
3. Gain Score
In this study, gain score was used as primary data to calculate t
test
after finding out the mean score, standard deviation score and standard error mean score. It is the
difference score between students’ pre-test score and post-test score. The following is the description of the scores:

Table 4.3 shows that -3 was the lowest students’ gain score in experimental
class and 25 the highest students’ gain score in experimental class while -8 was the
lowest students’ gain score in controlled class and 18 the highest students’ gain score
in controlled class. In addition, 404 was the total students’ gain score in experimental
class and 138 was the total students’ gain score in controlled class. The experimental
class has the average score of 13.46 and the controlled class has the average score of 4.6.
