below of KKM score. It means that only 13.04 who pass KKM score 70.
From the percentage above, it is shown the achievement students’ reading at VIII grade SMP Bakti Mulya 400 Jakarta is still
low. It could be seen from the diagram below:
Figure 4.1
The Result of Student’s Score in Pretest
2. Post-test I
After scoring the pretest in preliminary, the writer calculated the result of posttest 1 in the second meeting of cycle I. It
was to know the improvement from the pretest to posttest 1 result. However to measure that improvement, it was needed to know the mean
score of the class by using the formula as: _
∑x X =
── N
2 4
6 8
10 12
14 16
18 20
less 70 score 70
above 70 Pretest
_ 1435 X =
─── 23
_ X = 62.39
From the absolute numerical data, it was known that the mean score of the class in the posttest 1 derived 62.39. It gained any
improvement was 7.18 62.39-55.21 from the pretest or having 13.00 from the pretest to the posttest 1 result. To know that improvement into
percentage, the writer calculated as following:
y1 - y P =
─── X 100 y
62.39 – 55.21
P = X 100
55.21 7.18
P = ──── X 100
51.39
P = 13.00
In the first cycle of posttest 1, there were 8 students who passed the KKM 70. If it was calculated into class percentage, it was
derived 34.78 through the formula: F
P = ── X 100
N 8
P = ── X 100
23 P = 34.78
Based on the numerical data above, it showed 8 students have passed KKM score 70 and 15 students who got score under
KKM 70 . But it has development of percentage’s students’ score from
pretest before implementation of CAR. In another word, the applying Contextual Teaching and Learning method in cycle one is enough
effective to be used in students’ reading activity at VIII Grade SMP Bakti Mulya 400 Jakarta, but the writer has to do cycle two because
there were many students still got under KKM score 70. It could be seen from the diagram below:

of post-test II into three parts of calculation. First the writer calculates the mean score of the class, second students’ achievement or
