Abstract

Penelitian ini dilatarbelakangi oleh prestasi belajar matematika siswa yang belum mencapai KKM (65) siswa kelas IV SD Negeri 155708 PO Manduamas 2. Hal ini disebabkan metode pembelajaran yang digunakan oleh guru kurang variatif, hanya menggunakan metode ceramah sehingga minat belajar siswa menurun. Untuk mengatasi masalah tersebut, diterapkan model Team Games Tournament (TGT) yang dapat meningkatkan kemampuan matematika pada operasi hitung bilangan bulat untuk siswa kelas IV SD Negeri 155708 PO Manduamas 2. Penelitian ini menggunakan metode penelitian tindakan kelas yang terdiri dari dua siklus. Teknik pengumpulan data menggunakan tes dan lembar observasi. Hasil penelitian menunjukkan, (1) siklus I pertemuan pertama rata-rata 57,14 (8 siswa lulus), (2) siklus I pertemuan kedua rata-rata 69,47 (11 siswa lulus) , (3) siklus II pertemuan pertama rata-rata 82,63 (tuntas 17 siswa), dan siklus kedua pertemuan kedua rata-rata 87,89 (tuntas 17 siswa). Disimpulkan bahwa penggunaan model Team Games Tournament (TGT) mampu meningkatkan hasil belajar matematika siswa kelas IV SD Negeri 155708 PO Manduamas 2.

Abstract

This research was conducted to investigate the effect of the Spaced Repetition Strategy on the vocabulary achievement of seventh-grade students at SMP Negeri 11 Padangsidimpuan. A quantitative method with a pre-experimental one-group pre-test and post-test design was applied in this study. The sample comprised 55 students who were selected using the total sampling technique. Data were obtained through observation checklists and a vocabulary assessment. The results showed that the students’ average pre-test score was 54.91, which improved to 74.94 in the post-test following the application of the Spaced Repetition Strategy. Furthermore, the observation of the strategy's implementation yielded a score of 90%, classified as “Very Good.” The hypothesis test demonstrated that the calculated t-value exceeded the critical t-value at the 5% level of significance (13.73 > 2.01). This finding confirmed that the alternative hypothesis was accepted, whereas the null hypothesis was rejected. Consequently, it can be inferred that the Spaced Repetition Strategy significantly enhanced students’ vocabulary mastery and supported more effective vocabulary retention through scheduled and repeated review practices.
