Deriving the Angles of a Convex Polygon through Realistic Mathematics Education Approach
Keywords:
realistic mathematics education approach, convex polygon, real-world context, mathematics performanceAbstract
Realistic Mathematics Education (RME) is a learning strategy that allows students to engage with real-world contexts. This study aimed to evaluate the performance of Grade 7 students in deriving the relationship between the exterior and interior angles of a convex polygon, identified as the least mastered competency, using the RME approach. A quantitative, quasi-experimental one-group pre-test and post-test design was employed, with 41 Grade 7 students from a National High School in Biliran, Philippines serving as the respondents. Data were analyzed using mean, standard deviation, and Wilcoxon signed-rank test. The pre-test results classified students’ performance as "Did Not Meet Expectations," while post-test results improved to "Fairly Satisfactory." The Wilcoxon signed-rank test revealed a significant difference between pre-test and post-test scores, demonstrating the effectiveness of the RME approach in enhancing students' understanding of the targeted competency. It is recommended that future studies explore broader settings, different competencies, and longer implementation durations for the RME approach.
