To investigate the underlying questions of the thesis hypotheses, two groups were selected. One was the control group another was the experimental group. The participants attended English classes for 90-minute lesson periods, 2 days a week 8 sessions each month. The entire period of the experiment was 2 months. The procedural steps are listed as follows:
a. Accessible subjects participated in this research from the total population of students. b. The students were assigned to two groups.
c. The experimental and control groups were determined.
d. A pretest was given to the students.
e. Treatment.
f. The post test was administered immediately after the treatment to diagnose the effect of the given treatment.
g. Statistical analysis was carried out on the gathered data to accept or reject the null hypothesis.
First of all, the pretest was given to the students who were studying at the intermediate level in all classes to
know the background knowledge of students.
Result indicated that students knew a little and there was no significant difference between the two groups and
we could safely claim that the two groups were highly homogenous. The pretest posttest control group design was as follows:
