CHAPTER IV RESEARCH FINDING

A. Data Description and Data Analysis

As described in previous pages that the writer held the field research at SMK Islamiyah Ciputat, Tangerang Selatan. He held the field research by taking students’ score of test Pre-test and post-test. The pre-test is given before the treatment is begun and the post-test is given after the treatment is finished. To find out the result of testpre-test and post-test the writer makes the table of the students’ score is as follow: Table 4.1 The score of pre-test and post-test experimental class Student Pre-test Post-test Gained Score 1 65 72 7 2 78 80 2 3 67 85 18 4 72 80 8 5 80 85 5 6 82 85 3 7 68 75 7 8 59 75 7 9 60 78 18 10 64 80 16 11 45 60 15 12 52 70 18 13 39 50 11 14 64 84 20 15 68 84 16 16 82 89 7 17 36 64 28 18 60 80 20 19 40 75 35 20 48 64 16 21 72 80 8 22 54 68 14 23 72 90 13 24 49 75 26 25 72 85 13 26 64 80 16 27 70 94 24 28 48 76 28 29 56 72 16 30 34 56 22 31 64 80 16 32 52 72 20 33 48 70 22 34 80 95 15 35 73 85 12 Total 2137 2693 556 Average 61.05

76.94 15.88

Based on table 1.1, we can see that the experimental class highest pre- test score was 82 while the lowest pre-test score was 34 and the highest post- test score of experimental class was 95 and the lowest of post-test score was 50, from the table above it can be concluded that the ability of student listening was increased.Moreover, it can be seen from the experimental class’ average score was 15.88compare with the control class’ average score was 7.34 it means that there is significant effect of using descriptive video in learning listening. From the student’s post-test score above it can be assumed that the experiment class has higher score than control class’ post-test score. Table 4.2 The score of pre-test and post-test in control class Student Pre-test Post-test Gained Score 1 60 68 8 2 59 61 2 3 64 70 6 4 64 69 5 5 38 50 12 6 59 70 11 7 73 81 8 8 67 70 3 9 63 68 5 10 69 70 1 11 61 66 5 12 50 59 9 11 61 66 5 12 50 59 1 13 67 70 3 14 64 69 5 15 54 66 12 16 73 80 7 17 58 65 7 18 59 61 2 19 63 70 7 20 64 73 9 21 70 79 9 22 56 79 23 23 60 75 15 24 68 68 25 59 71 12 26 67 70 3 27 61 66 5 28 73 82 9 29 57 70 13 30 59 60 1 31 60 68 8 32 71 77 6 33 50 55 5 34 67 71 4 35 58 75 17 Total 2165 2422 257 Average 61.85

69.2 7.34

Based on the table 1.2, we can see that the highest pre-test of control class was 72 while the lowest score was 50. And the highest score of post-test in control class was 82 while the lowest score of post-test in control class was 55. Moreover, the average score of control class was 7.34 if we compare with the average score of experiment class was 15.88, from the data above it can be concluded that the control class has lower score than experiment class, it means that there is no significant improvement of stude nts’ listening ability in control class.
