Upaya Peningkatan Kemampuan Pemahaman Matematis dan Kerja Sama Siswa Pada Mata Pelajaran Matematika Materi Pecahan Melalui Pendekatan Matematika Realistik Indonesia Di Kelas V SDN 3 Medayu
Kata Kunci:
Mathematical Comprehension Ability, Cooperation, Indonesian Realistic Mathematics ApproachAbstrak
The purpose of this study was to determine the improvement in mathematical comprehension and cooperation among fifth-grade students at SDN 3 Medayu through the Indonesian Realistic Mathematics approach to fractions. This study is a classroom action research conducted in two cycles, with each cycle consisting of two meetings. The study is considered successful if it meets the success indicators, namely at least 75% of students achieve a minimum proficiency level of 75 and there is an improvement in student collaboration from one cycle to the next. The results of the study indicate an improvement in students' mathematical understanding. In cycle 1, the average score was 72.8 with a mastery rate of 64.42%, while in cycle 2, the average score was 83.98 with a mastery rate of 85.43%. Student collaboration also improved. This is evident in the average score of 2.26 in Cycle 1, which meets the criteria for ‘adequate,’ and 3.05 in Cycle 2, which meets the criteria for ‘good.’ Based on the results obtained, it can be concluded that the mathematical understanding and collaboration of Grade 5 students at SDN 3 Medayu improved through the Indonesian Realistic Mathematics Approach in the fractions material.
