experimental class by applying Collaborative Strategic Reading CSR in teaching reading, and then the research observed the result through classroom observation
and test pre-test and post-test in order to know whether or not Collaborative Strategic Reading CSR is effective on

C. The Population and Sample of The Research
The population of this research was the first grade students of SMA Mathla‟ul
Huda Parung Panjang-Bogor. There are only two classes of the first grade, therefore the technique of sampling that used by the writer is quota sampling.
Quota sampling is a non probability sampling technique that is used when the researcher was unable to take a probability sample but is still able to select
subjects oon the basis of characteristics of the population.

In this research, the population were 70 first grade students in two classes. The writer took X.I as the experimental class that has 35 students and X.II as the
controlled class that has 35 students. X.I was chosen as the experimental class
because it had lower mean score in pre-test than X.II; X.I was 54.67 and X.II was 57.16 The experimental class was taught reading comprehension through
Collaborative Strategic Reading CSR technique, while the other was taught through Grammar Translation Method GTM. The teaching and learning process
was carried out for four meetings. In the last, the writer only got 30
students‟ data as sample in each class. This condition happened because there were some students who did not come in each
meeting, either in pre-test, treatment, or post-test. Hence, the writer decided to take only 30 students as sample in each class based on their attendance.
