3. Students combine their
sentences and construct a short descriptive text in
pairs. 4.
Students change their works to the other pairs and
analyze the generic structure and language
features of the text. 5.
Students together with the teacher discuss and identify
the generic structure and language features of the
descriptive text made by the students.
6. Students are asked to work
individually to write sentences based on the
flashcards given by the teacher.
7. Students combine their
sentences into a short descriptive text.
4.1.3 Post Test
The post test was conducted after the treatments. It was held on 29
th
June 2013. It was conducted for the experimental group and the control group. Inthe post test,
the students were asked to write a descriptive text. The test was used to measure the students‟ ability in writing descriptive text. In this test, the students were asked
to write descriptive text which describedrooster at least in ten sentences. They were given 40 minutes to do their test. After that, I scored and analyzed the result
of their work. In scoring the students‟ post test, I also used the same formula as I used in
scoring the students‟ pre-test. The following is the computation of the students‟ post test the control group:

From the charts above, the average scores of each component of writing on the two groups improved on the post-test. From those results, the average scores of
the two groups were analyzed. In details, it can be seen on the chart below:

PRE TEST POST TEST
From the chart above, the different average score between the control and experimental groups was shown. In the control group, the average score of the
pre-test was 65.07 and the post-test 76.67. From those scores, the different average score between the pre-test and the post-test of the control group was
11.60. While, in the experimental group, the average score of the pre-test was 65.47 and the post-test was 84.00. The different average score between those tests
was 18.53. It meant that the different average score of the experimental group was higher than in the control group.
It could be concluded that there was improvement of the experimental groups achievement after they received the treatment using BBC Nature video. It
was also proven by the t-test formula. The result showed that there was a significant difference between the control and experimental groups on their
writing product. The computation can be seen in Appendix.
