2013. For the experimental group, the researcher used photographs in Facebook as media. The researcher gathered the students into one group in Facebook account.
He put some materials in the group. The students of the experimental group also could do online for learning their materials by opening their Facebook account
whenever they wanted. For the control group, the researcher only did conventional teaching. He only gave some materials about descriptive text. The
students were not given photographs in Facebook as media.
3.3.5 Posttest
Posttest was the last step for collecting data in experimental research. It was held on 19
th
May 2013 for the control group and May 22
nd
2013 for the experimental group. The test given was the same as the pretest.
3.4 Scoring Technique
In this study, the researcher used an analytical method to give the score. The researcher used the scoring guidance adopted by from Brown 2004:144. There
are five aspects such as content, organization, grammar, vocabulary, and mechanics. The scoring is rated from 1 till 4. The adaptation was based on the
need of the study with the criterion in every component. The table below is the explanation about the scoring system:
