Hiệu quả phương pháp dạy học WEI4S trong việc bồi dưỡng năng lực chứng minh hình học cho học sinh lớp 9

Tóm tắt

Originating from the reality that many students struggle to apply knowledge in geometric proofs, there is a growing need to innovate more effective teaching methods. This study aims to evaluate the effectiveness of the WEI4S teaching method (Worked-out Examples Involving 4 Stages) in enhancing ninth-grade students’ geometry proof competence, compared to traditional instruction. Based on cognitive load theory, the WEI4S approach involves four stages: analysis, explanation, verification, and application. A quasiexperimental design was conducted with 79 ninth-grade students at Long Trung Secondary School (Tien Giang Province), including 39 students in the experimental group and 40 in the control group. After three weeks of implementation, the experimental group showed significant improvements in both test scores and components of geometry proof competence. The initial results suggest that the WEI4S method is a promising approach for teaching geometric proof at the lower secondary level.
