CHAPTER III THE IMPLEMENTATION OF THE RESEARCH
A. THE METHODOLOGY OF THE RESEARCH
1. The Place and Time of the Research
The research was held at “SMP” Sunan Bonang. It’s located on Dasana Indah Bonang Blok SJ Kelapa Dua Tangerang Banten. The writer
conducted the research about two months. The writer did the research for six meetings from 16
th
February up to 1
st
April 2011. It consisted of the pre-test on the first meeting, the application of Small Group Interaction
and whole class teaching on the second until the fifth meeting, and the post-test in the sixth meeting.
2. The Objective
of the Research
As mentioned in the first chapter that the objective of the study is to find the empirical evidence whether there is any significance different in
reading achievement of between the students who are taught by using Small Group Interaction and those who are taught using whole class.
3. The Population and Sample
The population of this study is 92 students from the seventh grade of “SMP” Sunan Bonang. The seventh grade consists of three classes.
Number of VII
1
is 31 students, VII
2
class is 31 students and VII
3
30 students. The grade of VII
3
as the experiment class was taught using Small Group Interaction and the grade of VII
2
as the control class was taught using Whole class. Both experiment class and control class were taken 20
p[students from the attending list using Purposive Cluster Sample. Because the writer assumes that 40 students represent the number of
students.
4. The Technique of Data Collecting
The writer used test to collect the data. The data were collected from the pre-test and post-test. The pre-test was administered before the
treatments and post-test was administered after the treatments.
5. The Technique of Data Analysis
In analyzing the data, the writer used Bivariat Comparational Analysis Technique. The technique is used to test the hypotheses whether
there is a significant difference between two variables which are tested. Before the writer analyzes the data, it is necessary to calculate the data into
the statistic calculation. The writer used formula to calculate the data.
is used to find whether there is a significant difference between the score of students’ achievement in learning reading comprehension by
using Small Group Interaction and Whole Class teaching. The experiment class is X variable and the control class is Y variable.
The formula of is expressed as follows:
= Note :
Mx = Mean of Variable X
My = Mean of Variable Y
SE = Standard Error
Prior the calculation of , there are several procedures to be
taken. They are as follows: a. Determining Mean of Variable X, with formula:
= b. Determining Mean of Variable Y, with formula:
= c. Determining Standard of Deviation Score of Variable X, with formula:
= d. Determining Standard of Deviation Score of Variable Y, with formula:
= e. Determining Standard Error of Mean of Variable X, with formula:
= f. Determining Standard Error of Mean of Variable Y, with formula:
=
g. Determining Standard Error of Difference of Mean of Variable X and Variable Y, with formula:
= h. Determining
with formula: =
i. The Testing of Hypotheses: Ha
: There is a significant difference Mean between Variable X and Variable Y.
Ho : There is no a significant difference Mean between Variable X and Variable Y.
j. Determining in significance level 5 with Degrees of Freedom
df: df =
