Improving Students’ Level Three Of Van Hiele Geometric Thinking On 3d Using Problem-Based Learning At St. James Senior High School

Abstract

This study aimed at improving students’ level three of van Hiele geometric thinking on 3D using problem-based learning at St. James Senior High School in the Sunyani Municipality of the Bono Region in Ghana. The study which was grounded in the positivist paradigm employed a quantitative research approach and a pre-test-post-test quasi-experimental design in analysing the data collected. The intact class sampling was used in selecting two classes of 50 students each for the study. The data collection instrument comprised of pre-test and post-test that was conducted before and after the intervention respectively. Findings from the study revealed a statistically significant difference in the achievement scores of students in the control and experimental groups. Specifically, the study found that students who received instruction based on the PBL and VHPBI recorded high mean sore than those in the control group who received instruction based on the conventional method of teaching geometry. The study therefore recommended that mathematics teachers should be introduced and trained to use the PBL and VHPBI for the effective teaching of geometry.
