Abstract

Rendahnya hasil belajar matematika siswa kelas XI di SMK N 1 BARUMUN karena kurangnya motivasi belajar yang disebabkan karena proses pembelajaran yang dilakukan kurang bervariatif dan kurangnya bahan ajar, metode pembelajaran yang digunakan masih konvensional (ceramah). Penyebab lainnya yaitu siswa hanya mampu menyelesaikan soal yang sejenis yang diberikan oleh guru. Namun, jika soal sudah beragam, siswa tidak lagi memahami soal karena siswa tidak dapat memahami isi yang tercakup dalam masalah, sulit bagi siswa untuk merencanakan langkah selanjutnya dan bagaimana menyelesaikan masalah yang sesuai dengan langkah-langkah dan indikator pemecahan masalah. Kemampuan pemecahan masalah siswa juga masih kurang baik dengan persentase kelulusan siswa dalam pretest sebesar 30%. Sehingga dalam upaya meningkatkan kemampuan pemecahan masalah matematis siswa salah satunya dengan pengembangan bahan ajar. Penelitian ini bertujuan untuk mengetahui bagaimana pengembangan bahan ajar matematika menggunakan model PjBL untuk meningkatkan kemampuan pemecahan masalah matematis siswa di SMK N 1 Barumun. Penelitian ini merupakan penelitian dan pengembangan (R&D). Dengan menggunakan model pengembangan 4D. Hasil penelitian ini menunjukkan bahwa: (1) Kevalidan bahan ajar mendapatkan nilai sebesar 75,81% berada pada kategori “valid”. Kepraktisan bahan ajar mendapatkan nilai sebesar 92,29% berada pada kategori “Sangat Praktis”. Keefektifan bahan ajar mendapatkan nilai sebesar 84,56% berada pada kategori “Sangat Efektif”. (2) Bahan ajar menggunakan model PjBL yang dikembangkan dapat meningkatkan kemampuan pemecahan masalah matematis siswa sebesar 56,66%.

Abstract

The purpose of this study was to improve the mathematical critical thinking ability of students in class VIII-2 SMP Negeri 1 Sosa by using the Team Games Tournament type cooperative learning model. Based on the results of the mathematical critical thinking ability test given to students, the number of students who completed the initial observation was 3 people, cycle I was 16 people, and cycle II was 23 out of 26 students. While the percentage of classical completeness in the initial observation was 11.54%, cycle I was 61.54%, and cycle II was 88.46%. The increase in the percentage of classical completeness was 76.92%. In addition, for each indicator of students' mathematical critical thinking ability, the percentage of mastery of the indicator of mathematical critical thinking ability was 76.92%. In addition, for each indicator of students' mathematical critical thinking ability, the percentage of mastery of the best indicator of mathematical critical thinking ability is indicator 3, namely the skill of recognizing and solving problems, which is 85.19%, while the lowest percentage of mastery is indicator 5, namely the skill of concluding Based on the results of this study, it can be concluded that the TGT type cooperative learning model can improve the mathematical critical thinking ability of students in class VIII-2 SMPN 1 Sosa

Abstract

This study aims to improve the mathematical problem solving skills of students in class X MIA-4 MAN 1 Padang Lawas by using the Index Card Match learning model. This type of research is a class action research conducted in 2 cycles, each cycle consists of 2 meetings. The subjects of this study were students of class X MIA-4 MAN 1 Padang Lawas in the 2024/2025 school year totaling 28 students. Based on the results of the mathematical problem solving ability test given to students, the number of students who completed the initial observation was 6 people, cycle I was 19 people, and cycle II was 25 out of 28 students. While the percentage of classical completeness in pre-research was 21.43%, cycle I was 67.85%, and cycle II was 89.29%. The increase in the percentage of classical completeness was 67.86%, from 21.43% to 89.29%. In addition, each indicator of students' mathematical problem solving ability increased in each cycle. The increase in the percentage of mastery of the indicator of problem solving ability that best understands the problem is 87.85%. While the lowest percentage of mastery of problem solving ability indicators is checking back, which is 77.14%. Based on the results of this study, it can be concluded that the Index Card Match learning model can improve the mathematical problem solving skills of students in class X MIA-4 MAN 1 Padang Lawas
