Penerapan Model Discovery Learning Dengan Bantuan Media Papan Gembira Pemecah Masalah Untuk Meningkatkan Hasil Belajar Matematika Siswa Kelas III

Abstract

Abstract: The background of this research stems from observations in the third-grade classroom, where some students easily lose focus due to the teaching method, which relies solely on lectures and explanations. As a result, the students' learning outcomes are below the Minimum Completeness Criteria (KKM). Therefore, this study aims to improve the mathematics learning outcomes of third-grade students by implementing the Discovery Learning model supported by problem-solving media using a cheerful board. This research is a Classroom Action Research (PTK) based on the Kemmis and McTaggart model (Pendidikan et al., 2003). The study was conducted in a third-grade class with 26 students. The data analysis techniques used were completeness analysis and comparative descriptive analysis. The results showed that students' learning outcomes met the KKM of ≥ 75. In the pre-cycle, the percentage of student completeness was 38%, with an average score of 61. In the first cycle, the completeness percentage increased to 65%, with an average score of 74. In the second cycle, the percentage of student completeness rose to 77%, with an average score of 77. From the findings, it can be concluded that the application of the Discovery Learning model supported by problem-solving media using a cheerful board can enhance the mathematics learning outcomes of third-grade students.
