CHAPTER III METHOD OF INVESTIGATION
In this chapter, I deal with the method of investigation and the data collection of the study. It consists of Research Design, Subject of the Study,
Hypothesis, Variable, Methods of Data Collection, Procedure of the Study, Instrument of the Study, Method of Analyzing the Data.
3.1 Research Design
Since I want to investigate the validity and the reliability of the instrument, I use a quantitative approach. The analysis of the instruments are expressed in the
language of mathematics and must, consequently, be evaluated and interpreted by means of appropriate statistical procedures. However this is only done on
designing the instrument for gathering the data. In doing the calculating of the findings, I use the average score to support the argument, this means I combine
the quantitative and qualitative approach.
3.2 Subject of the Study
This action research is held in SMA N 1 Kaliwungu, which is located at Jln. Boja Kaliwungu – Kendal. The subject of the study is the year XI students of
SMA N 1 Kaliwungu. There are 16 classes which consist of 6 classes of tenth grade, 5 classes of eleventh grade, and 5 classes of twelfth grade. On the average,
each class consists of 35 students.
I choose 35 students of XI IPS 2 which consist of 6 male and 29 female students. I take that class as a sample based on the technique called the purposive
sampling. Purposive sampling means choosing the sample with an underlying purpose Arikunto 2006:139. The choice of the subject based on the following
considerations: 1
Their reading abilities have more developed than their juniors but they still have a big interesting in reading.
2 They are not concentrating to have National Final Examination as their
seniors are.
