Peningkatan Hasil Belajar Matematika Melalui Model Pembelajaran Problem Based Learning Kelas 5 SDN 101739 Sei Mencirim

Abstrak

Mathematics instruction on identifying and measuring angles often still relies on lecture-based methods, which tend to be less effective. The Problem-Based Learning (PBL) model is considered superior, as it fosters greater student engagement and comprehension through problem-solving. This study integrates PBL with the use of origami paper and student worksheets (LKPD) to enhance group collaboration and learning outcomes among fifth-grade students at SDN 101739 Sei Mencirim regarding the topic of angles. The study employs Classroom Action Research (CAR) conducted over two cycles, encompassing planning, action, observation, and reflection. Data were collected through observation, documentation, and testing, and subsequently analyzed qualitatively. The findings indicate a significant improvement in both student learning outcomes and participation. The application of PBL, supported by concrete learning aids, proved effective in deepening students' understanding of the concept of angles. This research underscores the importance of utilizing relevant learning media and student-centered instructional models to improve Mathematics learning outcomes in the fifth grade of elementary school.
