4.2 Significant Difference between the Result of the Pre-test and Post-test The answer for The Second Problem
The first step before the experiment was conducted, the students were given a writing pre-test. After the experiment, the students were given a post-test. The
scores of the pre-test and the post-test were obtained from five components of writing which consist of organization, content, grammar, punctuation and style.
The range of each component score was 20. The students ’ score was gotten from
the sum of the total score of those five components. The students ’ score of the
experimental group and the control group can be seen in Appendices 8 and 9.
4.2.1 Pretest Finding
The pre-test was conducted on Thursday, 3 January 2011 for class X 7 as the experimental group, and for class X 5 as the control group. Those two classes
consisted of 34 students for each class. The purpose of this test was to know the students
’ ability in writing narrative text before the treatments were given. The result of the pre-test can be seen in Appendix 8.
Below is the chart of the students ’ average score which covers five components of
writing.
Chart 4.1 The Average Score of the Pre-test
From the result, the students ’ average scores were analyzed. The average
score of the experimental group was 47.74 and the control group was 46.79. It means that the students
’ achievement of the experimental group and the control group was relatively the same before the treatments were given. It was proven by
the t-test formula. The result showed that there is no significant difference in achievement between the experimental group and the control group on the pre-
test. The computation can be seen in Appendix 10.

4.2.2 Post-test Finding
The post-test was conducted on Wednesday, 19 January 2011 for all class. The purpose of this test was to know the students
’ ability in writing narrative text after the treatment were given. The result of the post-test can be seen in Appendix 9.
Below is the chart of the students ’ average score which covers five components of
writing.
Chart 4.2 The Average Score of the Post-test
From those scores, the average scores of the experimental group and the control group were analyzed. The average score of the experimental group was 62.65 and
the control group was 53.15. It means that the achievement of the experimental group was higher than the control group. It was proven by the t-test formula. The
result shows that there is a significant difference in achievement between the
