The independent samples t-test results indicated that there was no significant difference between the
experimental (M= 18.4, SD= 6.7) and control (M= 16.2, SD= 10.0) groups, t(78), = 1.2, p> 0.05.
8.1 Hypothesis 1
To test hypothesis 1, the mean scores, standard deviations and independent samples t-test values of post-test
scores (in mathematics) for students in both experimental and control groups were computed. The results are
shown in Table 2.
