When the mean of the experimental group and control group were compared,
the mean scores of both groups increased after the implementation.
Independent groups t-test was used to determine whether there was any
difference between the pretest scores of the experimental and control
groups. Descriptive statistical data on the pre-test scores of the
students in the experimental and control groups obtained from the
English achievement test are presented in Table 1.
