The post test mean score of the experiment group was 83.9 and the control group was 78.6 and the difference between the two means was 5.3. The t-test scores
show that it was 3.534 for the t t
table
. For the t=3. 534, for α=5 with df= 68, the
t
table
=1.669 be obtained. It was found that there was a mean score that increase differences between
the experimental and control group, where the mean score of the experimental group increase was higher than the control group. Since t t
table
, it means that the differences is significant. The computation showed that t = 3.534 1.669. The t
was higher than the t-table, therefore, it can be concluded that the differences was
significant.
4.4 Discussion
The objective of the study is to find to whether teaching simple past tense using Course Review Horay
technique can improve the students‟ mastery in simple past tense.
In the post test, the mean of the control group was 78.6, while in the experimental group was 83.9. From the statement above, it could be said that there
was significant difference between two means, and the result showed that the experimental group got better score than control group.
Based on the result, teaching simple past tense using Course Review Horay
was good, the average score was 83.9. To check the significant effect of the treatment, I analyzed it by using t-test formula, based on the calculation, the result
of the t-test was 3.534. I consulted the critical value on the t-table using 5 0.05 alpha level of significant and the degree of freedom which was 1.669. Since the
obtained t-value was higher than the critical value 3.5431.669, the difference was statically significant. It meant that there was a significant difference between
teaching simple past tense using Course Review Horay with teaching simple past tense using conventional method. This treatment really helped the students in
mastering simple past tense, especially regular and irregular verbs.
CHAPTER V CONCLUSION AND SUGGESTIONS
This chapter discusses the conclusion of the study based on the result of the study and suggestions for the students, teachers, and reader.
5.1 Conclusion
The purpose of this research is to find out whether Course Review Horay could improve students‟ simple past tense especially regular and irregular verbs mastery
or not. The subject of this study was eleventh grade students of SMA N 1 Subah in the academic year 20102011.
After doing the research, I come to the conclusion that the use of Course Review Horay
technique in improving students‟ mastery in simple past tense especially regular and irregular verbs is significant. It can be seen from the
computation, for the degree of freedom is 68, and α is 5 level significance, the t-test 3.534 which is higher than t-table 1.669. Since the test is higher than t-
table, it means that the difference is significant. In addition, the significance is shown that the increasing score between pre test and post test is 20. The mean of
the pre test score is 61.9 while the mean of the post test score is 83.9. Therefore, it can be concluded that Course Review Horay
could improve students‟ simple past tense especially regular and irregular verbs mastery.
