CHAPTER IV DATA ANALYSIS AND DISCUSSION
This chapter presents the result of the data analysis and discussion about the result. First, data of the pretest and the posttest, normality and homogeneity,
computation between two means, analyzing the t-test, and the pretest and posttest findings.
4.1 Data of the Pretest and the Posttest
Before the experiment was conducted, the students were given a pretest. The test was objectives test which there were 2 paragraphs with 20 items. After a series of
treatments, the researcher gave the posttest. The scores of the pretest and the posttest were obtained from the rating scale developed by Rebecca M. Vallette.
4.1.1 Pretest Finding
Pretest is the test that was held before giving the treatments in order to find out the prior knowledge or ability or skill of the test takers before the treatments were
given. In this case, the purpose of giving pretest was to investigate the students’ ability in reading. The pretest was conducted on July 17
th
2010.There were 30 students for Experimental Group, XI Science 1 and 30 students for Control Group,
XI Science 2 participating on the pre-test. The result of the pretest can be seen in appendix.

From the result, the students’ average score was analyzed. The average score of the experimental group was 67, and the control group was 66. It means
that the students’ achievement of the experimental and control group was relatively same before the treatments were given. It was proven by the t-test
formula. The result showed that there is no significant difference in the achievement between the experimental group and the control group on the pretest.
It means that the students’ achievement in reading skill is relatively poor. That was why a series of treatments to improve the students’ reading skill was needed.
4.1.2 Treatment on the Experimental Group
The treatment was conducted on July 20
th
and 21
st
for the class XI Science 1 as the control group. The treatments were held in the Computer Laboratory of
SMAN 1 Pegandon, Kendal. This class consists of 30 students. The students were taught by using Digital Story, as the media to improve their writing skill of
narrative text. Below is the table of the activities in doing the treatment.
