PENGARUH PERSEPSI ATAS MEDIA PEMBELAJARAN DAN EFIKASI DIRI TERHADAP PEMAHAMAN KONSEP MATEMATIKA

Abstract

This study aims to analyze the influence of students’ perceptions of learning media and self-efficacy on their understanding of mathematical concepts at public senior high schools in South Jakarta. Specifically, it examines: (1) the simultaneous effect of perceptions of learning media and self-efficacy, (2) the partial effect of perceptions of learning media, and (3) the partial effect of self-efficacy on students’ conceptual understanding of mathematics. This research employed a quantitative survey method. The sample consisted of 83 students selected through proportional random sampling. Data analysis was carried out using multiple linear regression. The results revealed that: (1) perceptions of learning media and self-efficacy together significantly influence students’ conceptual understanding of mathematics (sig. 0.000 < 0.05; F = 31.585), (2) perceptions of learning media significantly influence conceptual understanding of mathematics (sig. 0.000 < 0.05; t = 5.669), and (3) self-efficacy significantly influences conceptual understanding of mathematics (sig. 0.000 < 0.05; t = 6.041). Therefore, perceptions of learning media and self-efficacy can be considered important factors in improving students’ mathematical conceptual understanding.
