The findings of this study showed that there was no statistically significant gender difference
in mathematics achievement for students who were taught through STAD, CL teaching
strategy. Therefore the STAD, CL strategy proved to be more effective in enhancing
mathematics achievements for male and female students than the conventional teaching
methods.
STAD, CL teaching strategy proved better in removing the gender differences gap in
students`mathematics achievement. This is probably because teachers changed their role of
active teaching to that of supervising, clarifying concepts and organizing the learning process.
Earlier research by Wachanga (2002) in Kenya in support of this study indicated that
cooperative learning in co-educational secondary schools, despite improving achievement in
chemistry for both boys and girls; it favored girls more than the boys. However, in this study
both boys and girls seemed to benefit equally while learning mathematics cooperatively.
Therefore gender difference in achievement at KCSE mathematics examinations can be
minimized by using cooperative learning/ teaching strategy in mathematics classrooms
