Abstract
Abstract: This study aims to describe the progression of students' mathematics learning outcomes through the implementation of the Student Teams Achievement Divisions (STAD) cooperative learning model supported by Educaplay interactive media. Unlike previous STAD studies that typically measured learning outcomes by comparing pre-test and post-test results, this study focuses on the developmental patterns of students' learning outcomes throughout the learning process by taking measurements at every session. A descriptive quantitative approach was employed, involving 36 students from class XI.F.7 at SMAN 16 Padang. Instruction was conducted over six sessions covering the topics of functions and composite functions. Data were collected via web-based Educaplay individual quizzes at the end of each session and analyzed using descriptive quantitative methods based on a comparison of average quiz scores. The results indicate that the progression of learning outcomes was fluctuating but showed an overall upward trend. The average quiz score rose from 70.79 in the first session to 94.25 in the sixth session, representing an increase of 23.46 points or 33.15%. Declines observed in certain sessions corresponded to the increasing complexity of the material. These findings provide an overview of the gradual progression of learning outcomes during the implementation of STAD supported by Educaplay. Keywords: learning outcomes; mathematics learning; STAD; Educaplay; function composition. Abstrak: Penelitian ini bertujuan mendeskripsikan perkembangan hasil belajar matematika peserta didik melalui penerapan model pembelajaran kooperatif tipe Student Teams Achievement Divisions (STAD) berbantuan media interaktif Educaplay. Berbeda dengan penelitian STAD terdahulu yang umumnya mengukur hasil belajar melalui perbandingan pretest dan posttest, penelitian ini berfokus pada pola perkembangan hasil belajar peserta didik selama proses pembelajaran melalui pengukuran pada setiap pertemuan. Penelitian ini menggunakan pendekatan kuantitatif deskriptif dengan subjek 36 peserta didik kelas XI.F.7 SMAN 16 Padang. Pembelajaran dilaksanakan dalam enam pertemuan pada materi fungsi dan komposisi fungsi. Data diperoleh melalui kuis individu berbasis web Educaplay pada setiap akhir pertemuan dan dianalisis secara deskriptif kuantitatif berdasarkan perbandingan rata-rata nilai kuis. Hasil penelitian menunjukkan bahwa perkembangan hasil belajar bersifat fluktasi tetapi cenderung meningkat. Rata-rata nilai kuis meningkat dari 70,79 pada pertemuan pertama menjadi 94,25 pada pertemuan keenam, dengan kenaikan sebesar 23,46 poin atau 33,15%. Penurunan pada pertemuan tertentu terjadi seiring meningkatnya kompleksitas materi. Temuan ini memberikan gambaran perkembangan hasil belajar secara bertahap selama penerapan STAD berbantuan Educaplay. Kata kunci: hasil belajar; pembelajaran matematika; STAD; Educaplay; komposisi fungsi.
