3. Sampling Technique
In this research, the writer used cluster random sampling technique. Fraenkel and Wallen state that the selection of groups, or clusters, of subjects rather than
individuals is known as cluster random sampling.

The writer used this sampling because all the classes were homogeneous and the writer took two classes. One class
was a control class and one class was an experimental class. The writer conducted the research at the eighth grade. The eighth grade consist of 4 classes, but was quite hard
to maintain all of the eighth grade students as the sample of this research, so the writer selected two classes as the sample.
