CHAPTER IV RESEARCH FINDINGS AND DISCUSSION
This chapter presents the result of the data calculation and also the summary of the data. There are two parts in this chapter. The first part discusses
the result of the experiment. The pre-test scores, the post-test score and the statistical result are shown as well. The second part discusses the methods that
may boost students’ writing.
4.1. Data Presentation
As a part of experimental research, the researcher had conducted several tests to measure the students’ writing skill. The tests were the pre-test and the
post-test, which were conducted to both groups. By conducting the pre-test and post-test, the researcher was able to measure the students’ writing skills before
and after the treatment. The experimental group was treated by using GAIL, while the control group applied ordinary teaching-learning activities. The results then
were calculated by using SPPS ver.20. In the following paragraphs, the pre-test score, the post-test score, and the statistical result of the data will be discussed and
analyzed. Table 4.1. shows that the mean score of the pre-test and the post-test of
both groups is different. The difference of post-test and pre-test of experimental group is 4.56 and 2.61 for the control group. The result suggested that the writing
performance of the experimental group is higher than the control group.
