Based on the table of gained score above, it can be seen that the gained score of experiment class was higher than the gained score of controlled class.
The data showed that most of the students in experiment class have progressed in understanding the verbs.
The data of gained score also showed that thirty-three students in experiment class have increased their ability in understanding verbs; moreover
there was one student in experiment class who has not progressed yet. One student who has not progressed yet can be seen from his score in pre-
test‟s result and post-test
‟s result. The table of gained score in experiment class also explained that the amount of the gained score was 687 and the maximum gained score was 40
while the minimum score of gained score of experiment class was -6. The data of gained score in controlled class showed that the amount of
gained score in controlled class was 377 and the maximum score was 26 while the minimum score of gained score was -13. Based on the gained score in controlled
class, the writer concluded that generally the students in controlled class also have progressed although as not much as the progress in the experiment class.
B. The Analysis of Data
In analyzing the data, the writer used the comparative technique where the writer compared the data of experimental class and the data of controlled class.
This technique was done in order to prove statistically whether there is any significant difference between the two variables; those are teaching verbs by using
cooperative learning and without using cooperative learning. After getting the data, the writer analyzed the results in both of the two
classes by using statistic calculation of the t-test formula. In this following table, the writer presented the result calculation of test in both of in order to know the
effectiveness of teaching verbs by using cooperative learning.
