Abstract

Linear programming is an essential topic in the high school mathematics curriculum, significantly contributing to students' decision-making and problem-solving skills. However, the complexity of its concepts and applications often becomes a challenge for students, making it challenging for them to translate real-world problems into mathematical models. This study aims to analyze various teaching strategies that have been implemented in linear programming instruction and evaluate their impact on students' learning outcomes. Through a systematic literature review, this study explores differentiated learning,cooperative learning models such as jigsaw, discovery learning, and the integration of technology like GeoGebra. The findings indicate that these methods effectively improve students' understanding and engagement in learning linear programming. By identifying the most effective approaches, this research provides insights for educators to implement better teaching methods, helping students grasp linear programming concepts more comprehensively and confidently.

Abstract

This research aims to investigate the relationship between critical thinking skills and communication skills on junior high school students' mathematical problem solving abilities. A total of 31 class VIII students were selected through simple random sampling as research subjects. To measure each ability, a test was carried out using essay questions which were then analyzed quantitatively using correlation and multiple regression analysis. From this research, the results obtained show that both the correlation between critical thinking and problem solving abilities and communication and problem solving abilities are both in the high category. The coefficient of determination test results obtained were 0.540, which means that the contribution of critical thinking abilities and mathematical communication skills together to problem solving abilities was 54%.   Penelitian ini ingin menyelidiki hubungan kemampuan berpikir kritis dan kemampuan komunikasi terhadap kemampuan pemecahan masalah matematis siswa SMP. Sebanyak 31 siswa kelas VIII dipilih melalui simple random sampling sebagai subjek penelitian. Untuk mengukur masing-masing kemampuan dilakukan tes menggunakan soal uraian yang selanjutnya dianalisis secara kuantitatif dengan analisis korelasi dan regresi berganda. Dari penelitian ini didapati hasil bahwa baik korelasi antara kemampuan berpikir kritis dan keterampilan menyelesaikan masalah maupun kemampuan komunikasi dan keterampilan menyelesaikan masalah sama-sama berada pada kategori tinggi. Hasil uji koefisien determinasi diperoleh sebesar 0,540 yang maksudnya besarnya kontribusi kemampuan berpikir kritis dan kemampuan komunikasi matematis secara bersama-sama terhadap kemampuan pemecahan masalah yaitu sebesar  54%.
