Abstract

This research aims to determine the application of the REACT strategy as an innovative approach in improving student chemistry learning outcomes. This research was carried out at MAN 2 Padang Lawas in the Even semester of FY 2023/2024. The population in this study were all students in class X MIA with an average number of students per class of 30 people. The sample consisted of 2 classes taken with determination because the number of class X MIA was only 2 classes. The experimental class applies the REACT strategy as an innovative approach, and the control class applies conventional learning. The data collected is processed from the Posttest results. The data were analysed using the independent t-test formula to test the research hypothesis and obtained tcount  ttable (4.67 1.67), so it can be concluded that the application of the REACT strategy as an innovative approach can improve student chemistry learning outcomes. Meanwhile, the gain test for the increase in learning outcomes for the experimental class was 72.60% in the high category, and the control class was 58.50% in the medium category. It can be concluded that the application of the REACT strategy as an innovative approach can improve students' chemistry learning outcomes.

Abstract

Penelitian ini bertujuan untuk mengetahui ada perbedaan yang signifikan hasil belajar siswa  melalui pembelajaran kooperatif STAD melalui media mind mapping dibandingkan dengan hasil belajar siswa melalui pembelajaran kooperatif STAD melalui media kartu soal. Penelitian ini menggunakan metode kuasi-eksperimen. Kelompok eksperimen I dengan model kooperatif STAD dengan mind mapping, kelas eksperimen II dengan model kooperatif STAD dengan media kartu soal. Hasil pengolahan data menunjukkan siswa pada kelas eksperimen I memiliki nilai rata-rata pretest 30,00 ± 7,73 dan posttes 78,00 ± 5,75 dengan rata-rata gain sebesar 0,70. Sementara siswa di kelas eksperimen II memiliki nilai rata-rata pretest 23,00 ± 8,19 dan posttest 66,20 ± 6,42 dengan rata-rata gain 0,57. Hasil uji statistik menggunakan uji t dua pihak menggunakan data  gain diperoleh thitung sebesar 4,885 sedangkan nilai t tabel 2,021 pada taraf signifikan α = 0,05, sehingga t hitung t tabel. Hal ini menunjukkan bahwa ada perbedaan peningkatan hasil belajar siswa yang diberikan dalam kelas eksperimen I dan kelas eksperimen II yaitu sebesar 12,63%.
