Abstract

This study aims to determine the improvement of learning outcomes of tenth-grade students on the topic of exponents through the implementation of the Problem Based Learning (PBL) model. The PBL model is oriented toward solving contextual problems, enabling students to be more active, creative, and critical in discovering mathematical concepts.The research method used is classroom action research (CAR) following the Kemmis and McTaggart model, which was carried out in two cycles. Each cycle consists of the stages of planning, acting, observing, and reflecting. The subjects of the study were 28 tenth-grade students at MA Islamiyah Syafiiyah. The instruments used were learning outcome tests (post-tests for each cycle), and the Minimum Mastery Criteria (KKM) was set at 75. The action was considered successful if the percentage of classical mastery reached at least 75%. The results of the study showed a significant and consistent improvement in learning outcomes from the pre-cycle to Cycle II. In the Pre-Cycle, the class average score was only 48.93 with a very low classical mastery of 3.57% (only 1 student met the KKM of 75). After implementing the PBL model, the class average score in Cycle I increased to 64.82, with a classical mastery of 21.43% (6 students met the KKM). The most optimal improvement occurred in Cycle II, where the class average score rose to 75.18 and the classical mastery percentage successfully reached 75.18% (21 students met the KKM). This improvement indicates that PBL not only helps students understand the concept of exponents more deeply, but also enhances motivation and active engagement in the learning process. Thus, the implementation of the PBL model can improve students’ learning outcomes on exponent material and is worth applying as an effective alternative learning strategy

Abstract

This study aims to improve the mathematics learning outcomes of grade IX students of MTsN 1 Probolinggo on the material of cubes and cuboids through the application of the Snowball Throwing learning strategy. This study is a Classroom Action Research (CAR) which is carried out in two cycles, including the planning stage, action implementation, observation, and reflection. The research subjects were 29 students with a Minimum Completion Criteria (KKM) of 75. Data collection techniques used learning outcome tests, observation, and documentation. The results of the study showed a significant increase in student learning outcomes. The average student score at the initial stage was 68.93 with a completeness of 58.62%. After the application of the Snowball Throwing strategy in cycle I, the average score increased to 89.48 with a completeness of 86.21%. In cycle II, the average score reached 95.52 with a classical completeness of 100%. These results indicate that the Snowball Throwing learning strategy is effective in improving students' mathematics learning outcomes on the material of cubes and cuboids. Â
