PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE TWO STAY TWO STRAY UNTUK MENINGKATKAN HASIL BELAJAR DALAM PEMBELAJARAN MATEMATIKA PADA SISWA KELAS III B DI SD NEGERI 6 BATUBULAN

Abstrak

Penelitian ini merupakan Penelitian Tindakan Kelas (PTK) yang bertujuan meningkatkan hasil belajar matematika siswa kelas III B SD Negeri 6 Batubulan melalui penerapan model pembelajaran kooperatif tipe Two Stay Two Stray (TSTS). Latar belakang penelitian adalah rendahnya hasil belajar pada materi perkalian bilangan cacah akibat pembelajaran yang masih berpusat pada guru. Penelitian dilakukan dalam dua siklus dengan tahapan perencanaan, pelaksanaan, observasi, dan refleksi. Subjek penelitian berjumlah 40 siswa. Data dikumpulkan melalui observasi, wawancara, dan tes, lalu dianalisis secara kualitatif dan kuantitatif. Hasil menunjukkan peningkatan signifikan pada rata-rata nilai dan ketuntasan belajar, di mana pada siklus II ketuntasan mencapai lebih dari 85%. Dengan demikian, model TSTS efektif meningkatkan hasil belajar matematika siswa.

This study is a Classroom Action Research (CAR) aimed at improving the mathematics learning outcomes of third-grade students at SD Negeri 6 Batubulan through the implementation of the cooperative learning model Two Stay Two Stray (TSTS). The background of the study stems from low student achievement in multiplication of whole numbers, which was caused by teacher-centered conventional learning methods. The research was conducted in two cycles consisting of planning, implementation, observation, and reflection. The subjects were 40 students. Data were collected through observation, interviews, and tests, and analyzed both qualitatively and quantitatively. The results showed a significant increase in average scores and learning mastery, with over 85% of students achieving mastery by the end of the second cycle. Therefore, the TSTS model is effective in improving students’ mathematics learning outcomes.
