Peningkatan Hasil Belajar Peserta Didik pada Materi Bangun Datar dengan Pendekatan CRT (Culturally Responsive Teaching) Kelas IV SDN Bandungrejosari 2 Malang

Abstract

This classroom action research aimed to improve student learning outcomes in the topic of flat shapes using the Culturally Responsive Teaching (CRT) approach integrated with Reog Ponorogo, a traditional Javanese art form. The research was conducted in Class IV of SDN Bandungrejosari 2 Malang during the even semester of the 2024/2025 academic year. It involved two cycles, each consisting of planning, action, observation, and reflection stages. Reog Ponorogo cultural elements—such as mask shapes and costume ornaments were used as contextual tools to help students better understand geometric concepts. The subjects were 28 students (17 boys and 11 girls). Data were collected through observation, tests (pre-test and post-test), and documentation. The results showed significant improvement. In the pre-cycle, only 1 student (4%) met the minimum mastery criterion (KKM = 75) with an average score of 35.89. In the first cycle, 18 students (64%) passed with an average of 76.75. By the second cycle, 21 students (75%) achieved mastery, and the average score rose to 81.71. The study concludes that integrating local culture through CRT enhances student engagement and learning outcomes in elementary mathematics.
