treatment. When the results were compared, the post test result showed improvements in the students’ writing competence. Based on the result, the writer concluded that there is a significant difference in achievement between the students of the experimental group that was taught by using authentic song lyrics as media and the students of the control group that was taught by using pictures as media. The following table is the table which shows the average score of pre test and post test difference based on the five components. Table 4.13 Pre Test and Post Test Difference of the Experimental Group Test Five Components Organization Content Grammar Punctuation Style Pre Test 13.235 13.118 12.029 12.412 12.029 Post Test 15.323 15.559 13.823 14.294 13.5 From the table above, it can be seen that there is an improvement in the post test of the experimental group for each component. We can see from the table that the students made improvements in overall components of writing. The improvements would be discussed as follows. 4.3.1.1 Students’ Organization in Writing As mentioned in chapter II, the organization meant how the students organize their writing. This component required that the content in writing should be well organized from the introduction, body, and the conclusion of the text. After analyzed the students’ project, it was found that the students’ competence in organizing sentences into a good paragraph was poor at the first time before treatment. They arranged sentences to introduce the participants in narrative not clearly enough. So, it is able to influence the body of narrative text, if they arranged completed introduction, the body of the text was also clear. But, if they arranged uncompleted introduction, they produced confused plot of the story. Some of them also produced inappropriate title in the story. In pre test, their average score in organization component was 13.235. It means that almost all of them produced unclearly introduction in the beginning of their story. After being given the treatment by using “authentic song lyrics” as media, the students’ organization in writing improved. They were not producing uncompleted introduction anymore and they used more appropriate title in the story to construct better narrative text than before given treatment. It can be proved by the average score of post test in organization component. They got 15.323 in the organization component. The following table shows the improvement of their competence in narrative in the organization component: Table 4.14 Students’ Writing Organization Test Component Organization Pre Test 13.235 Post Test 15.323
