Effects of Practical Work Approach on the Performance of College Students in Graph Theory

Abstract
The role of mathematics in manís life is an established fact. However, the marked difficulty experienced by students in learning mathematics as noted by the researcher calls for the need of alternative approaches to enhance performance. This paper dealt with the effects of practical work approach on the performance of college students in Graph Theory, specifically on the interaction effects of teaching approach with mathematical ability and manipulative skills. The post test-only control group true experimental design was used. Findings showed that below-average and above-average mathematical ability students taught by practical work approach performed better than their counterparts in the conventional approach. Moreover, the students with high and low manipulative skills taught by the practical work approach performed better than those students with high and low manipulative skills taught by the conventional approach. Furthermore, results of the ANCOVA revealed a significant interaction between teaching approach and mathematical ability. Overall, the practical work approach as a teaching strategy was shown to be significantly effective in improving performance of the students in Graph Theory. Practical work approach should be adopted by teachers to enhance performance of students in said course.
