Abstract

Mathematics learning on the topic BRSL, particularly the determination of surface area, is often hampered by the abstract nature of the concept and the lack of adequate visual representation. This condition has the potential to hinder students' conceptual understanding and mathematical reasoning abilities. We often find low student understanding and learning outcomes on this material. This luper borubung teaching aid is based on the urgency of developing learning aids that can bridge the gap between theory and visual reality. Students are introduced to the use of the luper borubung teaching aid, then given a test at the end of the activity containing BRSL material. The test results showed 71% of students in the good category. Students are enthusiastic, the learning atmosphere is more enjoyable and meaningful because they construct their own knowledge with the help of the luper borubung teaching aid.

Abstract

Curved-sided geometric shapes have a high level of abstraction, often leading to misconceptions and difficulties in visualizing threedimensional shapes. The Jigsaw cooperative model can enhance interaction and conceptual elaboration through the division of learning roles among students, while the guided discovery method helps students understand concepts and the origins of formulas more deeply. The use of teaching aids also provides concrete experiences that can strengthen visualization and reduce misunderstandings. The synergy of these three approaches has the potential to create more effective, active, and meaningful learning, while meeting the demands of current learning and curriculum that emphasize collaboration, exploration, and conceptual understanding. The study used a qualitative descriptive approach because the purpose of the study was to describe the application of the jigsaw cooperative learning model with the guided discovery method assisted by teaching aids on the surface area of curved-sided geometric shapes. The research subjects were grade IX students. Data were collected through observation, tests, and documentation. Based on the results of observations of student attitude assessments, the percentage of cooperative attitudes was obtained at85,29%, a responsible attitude of83,82%, a self-confident attitude of75%, and a meticulous attitude of75%. . Based on student learning outcomes, the average student score is69,41, and 71% of students met the Minimum Competency Criteria (KKM). These findings confirm that this learning strategy is effective in creating an active and meaningful learning environment
