Upaya Peningkatan Hasil Belajar Matematika Materi Keliling Dan Luas Bangun Datar menggunakan Cooperative Learning Type Student Teams Achievement Division (Stad) di Sekolah Dasar
The purpose of this study was to improve the mathematics learning outcomes on the circumference and area of flat shapes in Grade IV students at SD N Karangasem Pengasih through the Cooperative Learning Type Student Teams Achievement Division (STAD) learning model.
This research method is Classroom Action Research (PTK) which consists of two cycles, each cycle includes: planning, implementation, observation, reflection and evaluation. The subjects of the research were fourth grade students at SD Negeri Karangasem Pengasih semester II for the 2021/2022 academic year consisting of 11 students, 7 male students, 4 female students. The data collection instrument used was observation and test sheets.
The results showed that using the Cooperative Learning Type Student Teams Achievement Division (STAD) learning model could improve the mathematics learning outcomes around and area of flat shapes for fourth grade students of SD Negeri Karangasem Pengasih. The results of observations in cycles I and II showed an increase. This can be seen in the percentage of students who completed the first cycle 63.63% (7 students) and the second cycle of students completed 81.81% (9 students). So there is an increase of 18.18%.
