The independent-sample t-test was also conducted to make a comparison of cooperative learning effects on
students’ attitudes towards mathematics between experimental group students in Boys’ and Girls’ schools. As
described in Table 5, the students of Boys’ and Girls’ school scored post-test mean of 4.77 (SD = 0.06) and 4.73
(SD = 0.06) respectively. The difference between these two post-test means was non-significant t (38) = 1.99, p >
0.053, which revealed that the experimental group students’ performance in attitudes towards mathematics in Boys’
and Girls’ schools were equivalent after cooperative learning integration.
