CHAPTER IV FINDINGS AND DISCUSSION
This chapter consists of data description, data analysis and data interpretation
of the research. A.
Data Description
The research finding will be presented in the following description. The
finding was obtained from the pretest and postest of the students. 1.
The Score of Posttest and Pretest
In this research, the experimental class was the students of class X MIA 5 at SMAN 3 South Tangerang City. This class had 40 students including 16 males
and 24 females. But the data that the researcher composed included only 37 students because the writing of the 3 students did not fulfill the requirements that
the researcher asked. Based on the test given, the pretest mean score achieved was 72.432.
Moreover, the students’ lowest score achieved was 57 and the maximum one was 88. In addition, the standard deviation showed
57.086 and the variance pointed 57.086. After treatment, the mean score achieved was 76.378. It pointed that the
means score of posttest was higher that pretest. The students’ lowest score of
posttest achieved was 60 and the maximum one was 91. In addition, the data showed that the standard deviation pointed 72.509 and the variance was 52.575.
The Calculation of frequency distribution, mean, range, variance, and standard
deviation of pretest and posttest can be seen on the table 4.1 and 4.2.

2. The Distribution of Students’ Comments
In this research, students were asked to assess and give comment among other students in a group. The participants divided into 10 groups. Each of them consist
3 to 4 students which commented to each other posts. The comments were divided into 2 kinds. The first is basic feedback which students only give statement
whether the post is good or bad without any explanation beyond. Then elaborated feedback refers to useful and meaningful comments given by students. In
providing elaborated feedback, usually students explain and describe errors and mistakes other students did. The table showed the distribution of pretest basic and
elaborated feedback provided by the participants can be seen on Appendix. The participants divided into 10 groups in order to make easier in giving
feedback to each other. In addition, other participants of other groups were freely commented in other participants’ post. The distribution of participants presented
in the table 4.3 below.
