4.1.3 Post Test

The post test was conducted after the treatments. It was held on 20 th April 2011. It was conducted for the experimental group and the control group. For the experimental group, Five-Minute Activities strategy was used in writing descriptive text. For the control group, the use of picture was used in writing descriptive text. The post test was used to measure the students’ ability in writing descriptive text. In this test, the students were asked to write descriptive text which described their Classmate at least in ten sentences. They were given 45 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: a. The form = 5 37 648 × = 87.57 b. The grammar = 5 37 484 × = 65.41 c. The style = 5 37 568 × = 76.76 d. The content = 5 37 596 × = 80.54 e. The mechanic = 5 37 504 × = 68.11 78 The following is the computation of the students’ post test the experimental group: a. The form = 5 38 652 × = 88.11 b. The grammar = 5 38 560 × = 75.68 c. The style = 5 38 620 × = 83.78 d. The content = 5 38 616 × = 83.24 e. The mechanic = 5 38 580 × = 78.38 Table 4.4 The Result of Post-Test Chart 4.2 The Result of the Post-Test of the Control and Experimental Groups Group Five Items Form Grammar Style Content Mechanic Control 87.57 65.41 76.76 80.54 68.11 Experimental 88.11 75.68 83.78 83.24 78.38 79 In order to show the result of the students’ test, I show it in form of grade which is suggested by Harris 1969: 134 as follows: Table 4.5 Harris’s Scoring Grade Criteria of Mastery Level A 91 – 100 Excellent B 81– 90 Very good C 71 – 80 Good D 61 – 70 Sufficient E 51 Insufficient The list below is the students’ achievement according to the grade for both groups Table 4.6 The Score of the Control Group Criteria of Mastery Level Frequency Percentage Pre ‐test Post ‐test Pre ‐test Post ‐test 91 ‐100 Excellent 2 5.4 81 ‐90 Very Good 2 9 5.4 24.32 71 ‐80 Good 9 20 24.32 54.05 61 ‐70 Sufficient 23 6 62.16 16.21 50 Insufficient 3 8.1 Total 37 100 100 80 Table 4.7 The Score of the Experimental group Criteria of Mastery Level Frequency Percentage Pre ‐test Post ‐test Pre ‐test Post ‐test 91 ‐100 Excellent 2 0.0 5.2 81 ‐90 Very Good 1 24 2.6 63.15 71 ‐80 Good 6 10 15.78 29.41 61 ‐70 Sufficient 25 2 65.78 5.2 50 Insufficient 6 15.78 0.0 Total 38 100 100 After counting the frequency, then I used the diagram in reporting the result of the test. 1 The Diagram of the Result of the Test from the Control Group Chart 4.3 The Result of the Test of the Control Group 81 The diagram above describes the result of the students’ ability in the control group. The vertical line shows the frequency of the control group, while the horizontal line shows the achievement of the control group. 2 The Diagram of the Result of the Test from the Experimental Group Chart 4.4 The Result of the Test of the Experimental Group The diagram above describes the result of the students’ ability in the experimental group. The vertical line shows the frequency of the experimental group, while the horizontal line shows the achievement of the experimental group.
