When the time was over, she asked the students to collect the test papers. After that, she scored the test and analyzed the result. The result of the both pre
and post-test can bee seen in appendix.
4.2 The Test Result
Based on the analysis of the students’ result of the composition which was scored using Heaton’ grid, each percentage of the total of the five items that are
fluency, grammar, vocabulary, content, and spelling are as follows :
Table 4.2 Percentage of the total of the five Items

21.64 20.17

20.39 19.80
4.2.1 Test Scoring
As being discussed in chapter III, after the writer conducted the post-test, she began to score the achievement as shown in appendix.
In order to know the students’ post-test achievement in detail, the writer used the following formula to find out the achievement of each items.
ΣOSc Stsc.Ss
Ssa = x 100
Where : Ssa =
student’s achievement
Σ = number of obtained scores
Σ = number of students
For the experimental group, the computation is like this : a. The fluency
Student’s achievement = = 79.88
b. The grammar Student’s achievement =
= 77.73 c. The vocabulary
Student’s achievement = = 81.97
d. The content Student’s achievement =
= 89.09 e. The spelling
Student’s achievement = = 83.03
For the controlled group, the computation is like this : a. The fluency
Student’s achievement = = 74.39
b. The grammar Student’s achievement =
= 71.21 c. The vocabulary
Student’s achievement = = 79.69
131.75 5.33

131.5 5.33
x 100
d. The content Student’s achievement =
= 77.57 e. The spelling
Student’s achievement = = 75.30
From the computation it is clear that the items of content of the experimental group got the highest percentage of the achievement, 89.09. This
occurred because using pictures in writing descriptive writing increase the student’s ability.
4.2.2 Level of Student’s Achievement The data were obtained from the student’s achievement of writing in
descriptive paragraph test. The following is the tables that show the average scores for pre and post-test for all items and each item.

According to the table above, the difference average between the pre-test of the experimental and control group is 0.42, the difference average between the
post-test of the experimental and control group is 1.57. The difference between pre-test and post-test of the experimental group is 2.78 and the difference between
pre-test of the control group is 1.63. Table 4.4

According to the table, the difference in each item after the treatment by using pictures was better than just by using explanation. 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 :
Table 4.5 Harris’s Scoring
Grade Criteria of
Mastery Level
A 91 – 100
Excellent B
81 – 90 Very good
C 71 – 80

To make the difference easier to understand, the writer applied the percentage scores into charts as follow :
Chart 1
The polygon describes the result of writing test obtained by the experimental and control group when pre-test Chart 1 shows the C were 60.66.
While the achievement of the control group, the student who got E were 06.06, the students who got D were 45,45 and the students who got C were 48.48,
