Effectiveness of using circle geometry board strategy in learning circle geometry towards form four students performance

This study aims to determine the effectiveness of Circle Geometry Board (CG-Board) strategy in learning Circle Geometry towards Form Four students’ performance. This study also examined students’ Van Hiele’s level of Geometric Thought. The pre-test and post-test non-equivalent control group quasi-experimental designed was used. The selection of subjects was conducted by cluster probability sampling involving 52 Form Four students at a school in Hilir Perak district. The subjects were divided equally into control and treatment group. A three-week intervention was carried out. The instruments used are prior knowledge test, a set of pre-test and post-test on Circle Geometry and observation checklist. Descriptive analysis was used to describe students’ performance in the topic while independent t-test was used to determine the differences between the teaching strategies. The result showed that there was an increase in students’ performance in both control and treatment groups. Based on the ttest analysis, the mean score of the treatment group was higher than the mean score of the control group significantly [t(50) = -19.294, p < 0.05]. The treatment group’s students’ performance gained significantly higher than the control group. The students’ Van Hiele’s level of Geometric Thought also showed an increase from visual to abstract thinking level. In conclusion, the effectiveness of using the CG-Board strategy in Circle Geometry has improved the students’ performance. The implication of the study shows that CG-Board strategy can be used to improve the effectiveness of teaching and facilitating of Circle Geometry among students
