CHAPTER III RESEARCH METHOD
A. Types of Research
This research is a quasi-experiment. It is aimed to obtain information that can be gained by actual experiment in a state that does not allow for control
andor manipulate all relevant variables Sumadi Suryabrata, 2012: 92. This research used the experimental group and the control group. Researcher
provided the treatment to the experimental group, while the control group was not given the treatment. This research used a quantitative approach, where
results of analysis presented in form of numbers then described and interpreted in a description Iqbal Hasan, 2004: 30. Results of this research were
indicated by the students ‟ learning outcomes in cognitive, affective and
psychomotor domains.
B. Research Design
According to Selltiz in Ertambang Nahartyo 2013: 75, research design is the overall order of conditions for collecting and analyzing data in a way to
achieve research objectives efficiently. Design of this research is “3 × 2”
factorial design which is interpreted in the following matrix:

Specification: IS-T
= student ‟s learning outcomes who has Informational Style by using
Teams Games Tournament TGT learning method NS-T = student
‟s learning outcomes who has Normative Style by using Teams Games Tournament TGT learning method
DAS-T = student ‟s learning outcomes who has Diffuse-Avoidant Style by
using Teams Games Tournament TGT learning method IS-C
= student ‟s learning outcomes who has Informational Style by using
conventional learning methods NS-C = student
‟s learning outcomes who has Normative Style by using conventional learning methods
DAS-C = student ‟s learning outcomes who has Diffuse-Avoidance Style by
using conventional learning methods Based on the table above, it can be explained that researcher wants to
determine the effect of learning methods with Identity Style as moderating variable in improving the students
‟ learning outcomes. Identity Style has three levels, are Informational Style, Normative Style and Diffuse-Avoidance Style.
There are two types of learning methods used in this research which are Teams Games Tournament TGT learning method and conventional learning
method. Thus, if manipulation combined by factorial, this experiment will have six cells, there are student
s‟ learning outcomes who has Informational Style by used Teams Games Tournament TGT learning method IST, the
student ‟s learning outcomes who has Normative Style by used Teams Games
Tournament TGT learning method NS-T, student ‟s learning outcomes who
has Avoid-Diffuse Style by used Teams Games Tournament TGT learning method DAST, student
‟s learning outcomes who has Informational Style by used conventional learning method IS-C, student
‟s learning outcomes who has Normative Style by using conventional learning method NS-C, student
‟s learning outcomes who has Diffuse-Avoidance Style by used conventional
learning method NAS-C Ertambang Nahartyo, 2013: 99-100.
