CHAPTER III RESEARCH METHODOLOGY
A. Research Method and Design
1. Research Method
The method of this research was quasi-experimental research. Quasi- experimental research is also called post hoc, or after the fact, research because
the actual research take place after the assignment of groups. Because assignment has already taken place, the researcher has a high degree, but not the highest
degree, of control over the cause of whatever effects are being examined.
1
Quasi- experimental research by using pre-test and post-test control group design used in
this research. The research is categorized as a quasi-experimental research about the effect
of mind mapping technique on students’ writing of descriptive text. In quasi experimental research, the writer not give a random assignment as in true
experimental research because randomly assigning to two groups would disrupt the classroom learning.
2
Quasi-experimental studies also focus on cause and effect, but they use pre-assigned groups. It focused on treatment and outcome.
2. Research Design
In addition, the pretest-posttest, nonequivalent control group design was chosen in this experimental research. Only two groups were required, an
experimental group and a control group, for the design its simplest form

. It means that the treatments of the research are conduct through the implementation
of two different methods or techniques in two different classes: experiment class and controlled class. There is Table 3.1 to make the explanation easier:
