CHAPTER III RESEARCH METHODOLOGY
A. Research Design
In conducting this research the researcherusedexperimental design because in order to know the influence of using think pair share technique in students’ narrative text
writing ability. Experimental design is the general plan to carrying out a study with and active independent variable.
48
In this research, the researcher used quasi experimental research, quasi-experiments include assignment, but not random
assignment of participants to groups. This is because the experimenter cannot artificially create groups for the experiment.
49
Instead, the researcherused two classes of students that consists of one class as the experimental class and another class as
the control class. In this research, the researcher used pretest and posttest.The researcherused the pre-
test and post-test design approach to a quasi-experimental design. In this research, the students in experimental class which used taught by using Think Pair Share technique
and the students in control class used taught by using freewriting technique. After getting the data, the researcherused analyze them by using quantitative approach, the
design is illustrated as follows

According to Sugiyono variable is something that can be object of research to get the information of everything about it.
51
In this research there are two variables, they are: 1. Independent variable
The independent variable in this research was Think Pair Share technique that is symbolized by X.
2. Dependent variable The dependent variable in this research was students’ narrative text writing ability
that is symbolized by Y
