Penerapan Model Kooperatif Learning Untuk Meningkatkan Hasil Belajar pada Materi Ekosistem Dengan Bantuan Media Diorama Untuk Siswa Kelas 3

Abstract

Abstract: This study aims to improve the learning outcomes of third-grade students on ecosystem material through the application of a cooperative learning model with the help of diorama media. The purpose of this research is to enhance the science learning outcomes of third-grade students at SDN Karangbesuki 4 using diorama media. This research was conducted in the third grade at SDN Karangbesuki 4 with a total of 24 research subjects, consisting of 13 female students and 11 male students. Diorama media was used as a concrete visual aid to help students understand the components of ecosystems and their interrelationships. The research method used was classroom action research (CAR), which was carried out in two cycles. Each cycle consisted of planning, implementation, observation, and reflection, and data were collected through learning outcome tests. Based on the research results, with the use of diorama media, there was an increase in the classical average score from the pre-cycle stage of 39.17, cycle I of 57.83, and cycle II of 75.13. The use of diorama media in learning can improve the learning outcomes of the science subject on ecosystem material for third-grade students at SDN Karangbesuki 4 in the 2024/2025 academic year. In conclusion, the cooperative learning model with diorama media is effective in improving the learning outcomes of third-grade students on ecosystem material.
