Total 1064
Average 53,2
To analyze the data of pre test, the first step is to get the mean score of the class. The following is the calculation:
Total score of students pretest = 1064 =
= = 53.2
From the calculation above, it was known that the mean score of the class in pretest is 53.2. In the other words, the students’ achievement score of
preposition of place before implementing Classroom Action Research CAR is 53.2.
The next step is to know the percentage of students’ score who passed the KKM 68 the writer computes as follows:
P = 25 From the computation the students score percentage in the pretest
25. It means that the students who passed the KKM are 5 students and the other 15 students were below the KKM.
e. The result of post-test I
To know the result of the posttests the writer made the table of students
’ posttest score. Here the result of students’ scores in the posttest through Total Physical response.

Furthermore, in the cycle I after getting s tudents’ score in the posttest
I, the writer analyzed the data in order to compare the result between pretest
and posttest I. There are two steps to know the comparing result of pretest and posttest I. T
hose are calculating the students’ improvement into percentage and calculating the class percentage.
The first step was calculating the mean score of posttest I. It was calculated as follows:
Total score of students post-test 1 = 1230
The calculation above shows that students’ mean score of posttest I is 61.5. It shows that there wasan improvement from pretest mean score. It could
be seen from the pretest mean score 53.2 to the mean score of posttest I 61.5.
Based on the result above, the percentage of the students’ scores from
the pretest to the posttest I is 15.60. It means that the score in cycle I is improved about 15.60 from the pretest score.
Afterwards, the writer would like to know the percentage of students who passed the KKM. It used the calculation as following:
