4.1.4 Post – test
Considering the result of students‟ achievement after having been given the
treatment, the post- test was conducted to measure the students‟ achievement. By
conducting post-test, it was to prove the effectiveness of the treatment given. Through the post-
test result, then, it was assumed that the students‟ achievement before and after the treatment was able to be analyzed.
The post-test of experimental group was held on Wednesday, March 30
th
2011 and for control group on Thursday, March 31
th
2011. Based on the post- result, the average score of the experimental group was 72.67 and control group
was 69.73. It shows that the students‟ achievement of the experimental group is higher than the control group.
4.2 Test Result
The students‟ composition was scored using Heaton‟s Grid. The following are the chart showing students‟ average score on both pre-test and post-test, covering
five-elements of the writing scoring system.

students‟ achievement of writing test. The following is chart showing the average students‟ achievement score of experimental and control group.
Chart 4.4 The Average Score of Pre-Test and Post-Test
of Control and Experimental Groups
According to the chart above, the difference average between the pre-test and post-test of the experimental group is 72.67
– 56 = 16.67 and for the control group is 69.6
– 56.67 = 12.93. It can be conclude that the difference after treatment by using old and new information was better than using jumbled sentences.
In order to show the result of the writing test, the writer shows it in the form of grade as suggested by Harris 169:134 as follows:
