narrative text by using story mapping strategy was appropriate with the planning that had been discussed by the writer and the teacher
previously. In this case, every action was planned as good as possible so
that the reading activities could be accomplished well.
C. The Discussion of the Data After Classroom Action Research CAR
The discussion of the data after implementing the action consisted of two parts. Those were the result of the result of posttest. For further descriptions as
following:

To compare the test result between pretest and posttest of each cycle, the writer uses some steps. Those are calculating the students mean score of the test,
calculating the class percentage, and calculating the students’ improvement score from pretest to posttest 1 and 2 into percentage. Based on the table above, it is
shown that the lowest score of pre-test is 28 and the highest score of pre-test is 76.
The mean of s tudents’ scores of pre-test is:
∑ Pre-test: ̅
̅ ̅
It is shown from calculation above that student’ reading means score before using story mapping or before implementing Classroom Action Research CAR
is 48.35 . It is taken from the students’ pre-test score average.
After that, the writer analyzed the data to know the percentage of students’
score who passed the KKM 70. It is calculated by using formula as follows:
From calculation above, the students’ score percentage in the pre-test is 2.94. It means that there is 1 student who passed the KKM and there are 33
students’ scores which still below the KKM. After that, in the cycle 1 of CAR, the writer calculates the result of post-test 1
to know the students’ score improvement from the pre-test to pre-test 1 result. Still based on the table above, the writer concluded the lowest score of post-
test is 60 and the highest score is 90 which indicated that the post-test 1 score is higher than the pre-test score.
The mean of students’ scores of post-test 1 is:
̅
̅ ̅
From that calculation, the students’ mean score of posttest in cycle 1 is 61.64. It proves that there are some improvements from the pretest mean score. It could
be seen from the pretest mean score 48.35 to the mean score of posttest 1 51.64. The improvement of the average of students’ scores in pre-test and post-test 1
is: ∑ Post-test 1 - ∑ Pre-test = 61.64 - 48.35 = 13.29
The next step is to get the percentage of students’ improvement score from pretest to posttest 1. The writer computes by using as follows:
According to the calculation above, the percentage of the students’ improvement score from pre-test to pest-test 1 is 27.48. It shows that the score
in cycle 1 has improved 27.48 from the pretest score. After that, the writer calculates data to know the percentage of students who
passed the KKM in post-test 1. The calculation is as follow:
