H. The Technique of Data Analysis
The analysis qualitative data used in this study was using descriptive analysis from the
students’ activities during teaching learning process, and the interview before and after Classroom Action Research CAR. In this case, the
writer collected the entire data which have gained. In analyzing the numerical data, first 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 on grammar.
It uses the formula:
3
_ X : mean
x : individual score n : number of students
Second, the writer tries to get the class percentages which pass the minimal mastery level criterion KKM considering English subject gains
score sixty eight 68 which are adapted from the school agreement at MTs Darul Hikmah Pamulang.It uses the formula.

P : the class percentage F : total percentage score
N : number of student

Third, after getting mean of students’ score per actions, the writer identifies whether or not there might have students’ improvement score on
grammar comprehension from pre-test up to posttest score in cycle 1 and cycle 2. In analyzing that, the writer uses the formula.
5
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. The Criteria of the Action Success
The action is considered success if it can exceed the criteria which have been determined, and fail if it cannot exceed the criteria which have been
detained. In this study, the research will succeed when there is 70 students who pass the Kriteria Ketuntasan Minimum KKM, which is 68. In addition,
they could achieve some improvement scores from the pre-test until the second post-test in cycle two. If the criterion of the action success achieved, it

means that the next action of the Classroom Action Research CAR would be stopped, but if this condition has not been reached yet, the alternative action
would be done in the next cycle.

CHAPTER IV RESEARCH FINDINGS
This chapter presents the research findings based on the analysis of data collected from the implementation of CTL
to improve students’ understanding on degrees of comparison of adjectives in two cycles. The research findings are
described in three parts: data description, data analyzing and data interpretation.
A. Data Description
1. Before Implementing the Action
a. The Result of Pre Interview
Pre interview was held on Monday, March 5
rd
2012. Here, the writer asked some question to the teacher related to the teaching
learning process degrees of comparison of adjectives. The questions were divided into three categories. Those were general condition in
English class primarily on students’ performance and students’ achievement, the difficulties faced by students in understanding degree
of comparison of adjective, and the strategies used by the teacher to solve the students’ difficulties in understanding degrees of comparison
of adjectives.
First category discussed about the general condition in English clas
s primarily on students’ grammar achievement of the test and students’ activities. The teacher said that most of students who did not
like English class; they gained low competence in English. Besides, they still faced obstacle in following the English lesson. They thought
English as a complicated then considered that grammar as the most difficult one in learning English primarily on VIII

class which derived the lowest score of grammar test among the other second grade
classes. Moreover, the teacher stated that most of them were hardly to pass the KKM 68.
The second category discussed about the students’ difficulties in understanding degrees of comparison of adjectives. It was related to the
