| Abstract: This study sought to investigate the impact of a problem solving approach in the teaching of Graphs of Functions, a topic in the high school mathematics syllabus. The study sought answers to the following question: What is the impact of a problem solving teaching approach of Graphs of Functions? A quantitative paradigm was used to gather data from participants. A pre-test-post-test control design was used to assess the impact of a problem solving approach in teaching this topic. Also, a sample of 60 students was drawn and these were randomly assigned to the experimental and control groups. Each group was pre-tested using the same test after which a one week problem based teaching was administered to the treatment group. The same test with altered numbering on the test items was also administered to both the control and the experimental groups after the treatment. The findings revealed that, the experimental group performed better in its post-test as compared to the pre-test. Moreover, a comparison of the post-test scores revealed that the experimental group performed better than the control group. The study therefore concluded that a problem solving approach could improve the learners’ grasp of Graphs of Functions. The study therefore recommends that problem solving approach be used in teaching of Graphs of Functions. Learners should also be drilled through the process of problems to cement their grasp of the topic. |
