H. The Technique of Data Analysis
The analysis qualitative data used in this study is the observation of studen
ts’ activities during teaching learning process, and the interview before and after Classroom Action Research. And then, in analyzing the numerical data firstly
the writer tries to get the average of students’ score per action within one cycle. It is used
to know how well students’ score as a whole in understanding the passive form of simple past tense. It uses the formula:
2
_
X : mean
x : individual score n : number of students
Second, the writer tries to get the class percentage which pass the minimal mastery level criterion KKM considering English subject gains score 70
seventy which is adapted from the school agreement at MTs. Al-Mujahidin Cikarang. It uses the formula:
3
P : the class percentage F : total percentage score
N : number of students Third, after getting mean of students’ score per actions, the writer
identifies whether or not there might have students’ improvement score from pre-

test up to posttest score in cycle 1 and cycle 2. In analyzing that, the writer uses the formula:
4
P : percentage of students’ improvement y : pre-test result
y1 : post-test 1
P : percentage of students’ improvement y : pre-test result
y2 : post-test 2
I. Criteria of the Action Success
In this study, the Classroom Action Research will succeed when 75 could pass the target score of Kriteria Ketuntasan Minimal KKM.
5
The KKM that must be attained considering English subject is 70 seventy which is adapted from the
school agreement MTs Al-Mujahidin since 2009. If the criterion of the action success achieved, it means that the next action of the Classroom Action Research
would be stopped, but if this condition has not been reached yet, the alternative action would be done in the next cycle.
