experimental group as a group that gets the treatment and the control group that did not get treatment.
5
The researcher implements Collaborative Strategic Reading CSR technique in the first class and Grammar Translation Method is implemented in
the second class. This study focuses on giving treatment to the experimental class by applying Collaborative Strategic Reading in teaching reading, and then
the researcher observes the result through classroom observation and test.
C. The Population and Sample
The researcher conducted the experiment of SMA PGRI 109 Kota Tangerang. The population of the research is the second grade of senior high
school. There are 4 classes of second grade. The total number of students or population is 140 students. The sampling technique of this research is
Purposive Sampling, because it takes the sample with any consideration.
6
In this research, the researcher chooses XI IPA 1 as the experimental class and XI
IPA 2 as the control class, because according to the English teacher in that school, those classes were appropriate to become the object of this research.
Both of those classes consist of 35 students. The researcher chooses the second- grade because reading skill is the crucial skill for them in the preparation of
facing the National Examination in the third grade.
D. The Instrument of the Data
The instrument of this study is a test of English which consist of 25 multiple choice questions taken from some books of English for Second Grade.
The 25 items of the tests is tested to the students from the third grade. After the test is applied,
the researcher measures the instruments’ validity and reliability used ANATEST. For the ANATEST result, it can be seen on appendices.

E. Data Collection Techniques
Technique of collecting data in this research is using pretest and posttest that was given to both experimental class and control class. In this research, the
researcher gave pre- test to see students’ basic capability in reading before using
Collaborative Strategic Reading CSR technique in reading class. The next test was post-test which will measure the effectiveness of CSR technique towards
students’ reading comprehension achievement in a certain period.
F. Data Analysis Technique
The researcher used T-test to find out the differences between the students’ scores which were taken from pre-test and post-test in experiment
class and control class. Before calculate the hypothesis testing, the researcher first measure normality and homogeneity test. Moreover, the writer analyzed
the data by using SPSS v.16 for Windows software to do the normality test, the homogeneity test, and T-test.
1. Normality Test
Normality test is done towards two classes; those are experimental class and control class. Normality Test is used to know whether the data from both
sample groups which is examined comes from the population of normal distribution or not. The normality test is done with SPSS v.16 for Windows with
requirement as follows: If the significance score of Asyim Sig 2 tailed 0.05, so the data is come from the normal population, but if Asyim Sig 2 tailed
0.05, so the data is not come from normal population.
2. Homogeneity Test
After normality test gives indication that data is distributed normally, so it needs to do homogeneity test. Homogeneity Test is used to know the
similarity of the two conditions or population. The researcher also uses SPSS
v.16 for Windows to do homogeneity test which is Analyze-Compare Means- One Way ANOVA.
3. Hypothesis Testing
For The Hypothesis Test, the researcher uses T-Test to find out whether there is the differences between two variables in this study. The researcher uses
SPSS v.16 for Windows program to find the result. After gaining the t-
value
, the researcher compares T-
value
and T-
table
. Testing hypothesis uses criteria with significance degree 0.05. The
conclusion is gained as follows: If t-
value
t-
table
, the H
o
is accepted. If t-
value
t-
table
, the H
o
is rejected or H
1
is accepted.

technique on the students’ achievement in reading comprehension of
narrative text. H
: There is no influence of Collaborative Strategic Reading CSR technique on
the students’ achievement in reading comprehension of narrative text.
