In addition, the results of the students’ writing show the same positive improvement. From the results of the students’ writing it can be seen that
they benefited from the peer-feedback method and improved their writing abilities. Here is an example
of the students’ final drafts in Cycle II.
Figure 6: One of the student s’ final drafts in Cycle II
From the pictures above, it can be seen that the students’ improvement in their writing abilities. They had various ideas and vocabulary in writing
the descriptive texts. Their grammar had improved as well. Their mistakes in writing become lesser compared to Cycle I. Hence, it can be concluded
that the method and activities in Cycle II had helped the students to improve their writing abilities.

Before the researcher ended the research, the researcher held a post- test for the students. It was held on May 27
th
2013.
D. The students’ writing scores
After conducting the research, the researcher summarized the students’ writing scores helped by the collaborator. The researcher employed the
scoring rubric suggested by Jacob, et.al. 1981 in Weigle 2002:116. In order to get inter-rater reliability in the research, the researcher and the
collaborator became the raters. They compared the mean values in several aspects of writing which are content, organization, vocabulary, language use,
and mechanic. Besides that, the standard deviations were also presented in order to analyze the variability of the class.
The comparison of the students’ writing scores in the aspect of content is presented below.
Table 3: Comparison of the Mean Values and Standard Deviations of the Students’ Scores in the Aspect of content in the Pre-test, Cycle I, Cycle II,
and the Post-test Stages
Pre-test Cycle I
Cycle II Post-test
Mean Values 18.02
20.69 22.68
23.95 Standard Deviation
2.45 1.79
1.26 0.81
From the table above, it can be inferred that the students’ writing ability had improved in the aspect of content from pre-test up to the post-test. From
pre-test to Cycle I, the students succeeded to make 2.67 improvements. The
99
students also made an improvement of 1.99 from Cycle I to Cycle II. Meanwhile, the students progressed and scored 1.27 in the post-test compared
to scores in Cycle II. Besides that, the standard deviation of the pre-test was 2.45 which was
higher than the SD in Cycle I which was reached 1.79. Meanwhile, the standard of deviation in the post-test was decreased to 0.81 point. It was lesser
than the SD of Cycle II which was 1.26 . Hence, the students’ scores in post-
test in the aspect of content were the most homogenous scores compared to the other stages.
The students also made improvement in the aspect of organization. The comparison of the mean values and the standard of deviation from pre-test up
to post-test can be seen in the table below.
Table 4: Comparison of the Mean Values and Standard Deviations of the Students’ Scores in the Aspect of Organization in the Pretest, Cycle I,
Cycle II, and the Posttest Stages
Pre-test Cycle I
Cycle II Post-test
Mean Values
11.35 14.56
15.02 16.42
Standard Deviation
2.07 0.72
0.68 0.55
In the pre-test, the students scored 11.35. And then, the students improved 3.22 in the Cycle I and got 14.57 score. From Cycle I to Cycle II,
the students improved their scores for about 0.46 point. And the students
100
made improvement of 1.40 in the post-test compared to the scores in the Cycle II.
Meanwhile, the standard of deviation from pre-test to post-test gradually decreased. From Cycle I to Cycle II, the SD decreased from 2.07 to
0.72. The SD from Cycle II to post-test decreased from 0.68 to 0.55 compared to the SD in the Cycle II.
Hence, the students’ scores in the post-test were the most homogenous scores among the other stages.
The students also improved their writing abilities in the aspect of vocabulary. It can be seen from the table below.
Table 5: Comparison of the Mean Values and Standard Deviations of the Students’ Scores in the Aspect of vocabulary in the Pretest, Cycle I, Cycle
II, and the Posttest Stages
Pre-test Cycle I
Cycle II Post-test
Mean Values
11.05 14.58
15.11 16.37
Standard Deviation
2.12 0.85
0.73 0.71
The table above shows that the students had made improvement on their writing abilities dealing with the vocabulary aspect. In pre-test, the students
averagely scores 11.05 and improved to 14.58 in the Cycle I. Then, they improved for about 0.53 point in Cycle II. In the post-test, the students
averagely scored 16.37.
