Abstract

Purpose: Angle relationships remain a challenging topic in junior high school mathematics, as many students struggle to understand abstract geometric concepts through conventional, teacher-centered instruction. This study aims to describe the implementation of the Jigsaw cooperative learning model in teaching angle relationships to seventh-grade students, examining instructional implementation, student attitudes, and conceptual understanding throughout the learning process. Methodology: A descriptive qualitative approach was employed, involving 28 seventh-grade junior high school students in Jayapura, Papua, Indonesia, with data collected through observation, interviews, individual tests, and documentation, then analyzed using data reduction, data display, and conclusion drawing. Findings: Findings show that the Jigsaw cooperative learning model was implemented very effectively, with students actively engaging in expert-group and home-group discussions to exchange ideas and complete collaborative tasks. Students demonstrated good levels of cooperation, responsibility, curiosity, accuracy, and self-confidence, while most achieved very good to good understanding of angle relationships, supported by peer teaching, multiple representations, and meaningful social interaction consistent with constructivist learning theory. Significance: These results indicate that the Jigsaw cooperative learning model effectively enhances student engagement, positive attitudes, and conceptual understanding in mathematics learning, offering teachers a practical, collaborative instructional alternative for teaching geometry topics such as angle relationships in junior high school classrooms.
