PENGARUH PENDEKATAN PEMBELAJARAN DAN EFIKASI DIRI TERHADAP KEMAMPUAN PEMECAHAN MASALAH MATEMATIKA

Abstract

Mathematics is a subject that requires not only conceptual mastery but also the ability of students to solve problems related to everyday life. Field evidence shows that many students still experience difficulties in solving problems, especially those requiring analysis, logical reasoning, and creativity. This situation indicates the need for more effective learning strategies that can maximize student engagement. One of the most important is the learning method implemented by the teacher. Appropriate methods can facilitate students in connecting abstract concepts with real-world conditions, thereby enhancing the development of critical thinking skills. In addition, student self-confidence also plays a role in determining success. Students with high self-efficacy tend to be more confident, persistent, and do not give up easily when facing difficulties in mathematics.

The research method used was a quasi-experimental one, with a 2-Way ANOVA research design. The results of the study showed that: (1) there was a significant influence of the Learning Approach on Mathematical Problem-Solving Ability (2) there was a significant influence of self-efficacy on Mathematical Problem-Solving Ability and (3) there was a significant interactive influence of the Learning Approach and self-efficacy. Thus, the contextual approach was effective for students with both high and low self-efficacy in learning mathematics. Conversely, the constructivist approach was only effective for students with high self-efficacy, especially for improving Mathematical Problem-Solving Ability.
