PENGARUH METODE PEMBELAJARAN DAN EFIKASI DIRI TERHADAP LITERASI MATEMATIKA

Abstract

This study aims to analyze the effects of cooperative and conventional learning methods, as well as self-efficacy levels, on junior high school students’ mathematical literacy in Lebak Regency. A 2x2 factorial experimental design was applied with 222 students divided into experimental and control groups. Research instruments included a mathematical literacy test and a self-efficacy questionnaire. Data were analyzed using two-way ANOVA. The results revealed that students taught with cooperative learning achieved a higher mean score of 78.64 compared to those with conventional learning, who scored 70.12 on average. Self-efficacy also had a significant impact, with high self-efficacy students achieving a mean score of 80.27, while low self-efficacy students averaged 68.49. The interaction showed the best outcomes in the high self-efficacy–cooperative group, which reached a mean score of 82.45. These findings highlight that the combination of cooperative learning and high self-efficacy is highly effective in improving mathematical literacy. Teachers are encouraged to apply cooperative learning to foster collaboration, communication, and student confidence in solving mathematical problems.
