CHAPTER 3 RESEARCH METHODOLOGY
A. Participant of the study
1. Population of the Study
Population of this study comprises of 8
th
grade of secondary school students at
Bilingual School located in Bandung, Indonesia. 2.
Sample of the Study
One of the two classes was chosen as sample of this study, it consisted of 23 female students enrolled in even semester of a bilingual school located in Bandung,
Indonesia.
B. Time and Location
1. Time
Research was conducted from February 2013 until June 2013. Preparation stage was conducted from February 2013 until April 2013, implementation stage was
conducted in May 2013 and final stage was conducted in June 2013.
2. Location
Research was conducted in one of bilingual secondary school in Bandung, Indonesia.
C. Method and Design of Research
1. Research Method
Quantitative method was used n this research. Quantitative research method is explaining phenomena by collecting numerical data that are analysed using
mathematically based methods Aliaga and Gunderson, 2000. Non experimental study was chosen in this study consider that the researcher observing the
phenomenon and attempting to establish what caused it. This research investigate the current state of a variable or the relationships, other than causal, between
variables

2. Research Design
In this research, non experimental study descriptive design was conducted. This study classified as descriptive design consider the characteristics of this design that
makes careful descriptions of the current situation or status of variable of interest, attempt to describe systematically a situation, problem, phenomena, service or
program, or provides information about living conditions of a community or describe attitude towards an issue Kumar, 2005.
3. Procedure of the Research
This research was conducted through 3 stages which are defined below: a
Preparation Stage Activities that were conducted in this stage consist of:
1 Preliminary study and need analysis that consists of an extensive literature
study on the subject of implementation as well as appropriate literature related to science process skills, analyzing science curriculum which is used
at school and analyzing annual plan and science lesson material for 8
