CHAPTER III RESEARCH METHODOLOGY
This chapter presents the objective of the research, place and time of the research, population and sample, method of the research, technique of
collecting the data and the technique of analysis the data.
A. The Objective of the Research
The objective of this research is to find out if there is a significant difference of students’ reading score between students who are taught with
group work and students who are taught without group work. This research will point out whether group work is an effective way to teach reading or not.
If the students’ reading score of the class that taught with group work is higher than the class that taught without group work and if the difference is
significant, it means that group work is appropriate to teach reading.
B. Place and Time of the Research
This research took place in an Islamic junior high school called Madrasah Tsanawiyah Negeri Parung. It is located in Parung Bogor.
The school was established in 1982. It has 1132 students that are divided into 26 classes. Nine class for seventh grade, nine classes for eighth
grade and eight classes for ninth grade. There are 390 students of seventh grade. They are divided into nine classes, each class consist of 40-45 students.
In the eighth grade, there are 370 students that are divided into nine classes; there are 40-45 students in each class. And for the ninth grade, there are 377
students that are divided into eight classes, therefore each class consist of 45- 50 students.

The school has 73 teachers; all classes are handled by them in that school. The research were done for 5 weeks, there are 2 session every week
for each group experiment group and control group. It began on April 5, 2010 and it ended on May 21, 2010.
C. Population and Sample
The population of this research is students of eighth grade, they are 370 students. They were divided into nine classes, class 8.1 to class 8.9. The
writer thought that it is too large to do research to all of the students. Therefore, the writer use cluster sampling for the samples because it is more
effective to use in a large numbers of classes. According to Jack R. Fraenkel and Norman E. Wallen, “the selection of groups, or clusters, of subjects rather
than individuals is known as cluster sampling. Just as simple random sampling is more effective with large numbers of individuals, cluster sampling is more
effective with larger numbers of clusters”.

Based on the cluster sampling that is used by the writer in taking the sample, she took two classes randomly; there are class 8.5 as the control
group and class 8.6 as the experiment group. There are 42 students of each class. Unfortunately, two students of the experiment group were taken out
from the sample because they attended the class only three times. Therefore, the writer made it equal to help her in analyzing the data later. Those are 40
students in the experiment group and 40 students in the control group. So, there are 80 students as the sample.
