MEASUREMENT OF MATHEMATICAL PROBLEM SOLVING ABILITY BASED ON SELF EFFICACY CATEGORIZATION USING MIXED METHODS APPROACH
No full textProblem-solving ability is an important part of learning mathematics. The low ability to solve mathematics needs to get attention related to students' self-efficacy. This study aims to determine the level of mathematical problem-solving abilities based on the categorization of students' self-efficacy at high, medium, and low levels. This research was conducted in class XI SMAN 1 Konawe Utara with a total of 37 students as subjects. This type of research is descriptive quantitative and qualitative in the form of a mixed method. The research instrument consisted of tests of mathematical problem-solving skills, self-efficacy questionnaires, and interview guidelines. Data were analyzed using quantitative and qualitative descriptive analysis. The results of the study show that students with high self-efficacy are able to solve math problems following all stages of Polya; students with moderate self-efficacy are unable to follow all Polya stages, while students with low self-efficacy are unable to solve math problems following Polya stages. It was concluded that the level of self-efficacy of students had an influence on ability to solve math problems based on Polya's step

DEVELOPMENT OF TEACHING MATERIALS INTEGRATED MATHEMATIC REASONING ABILITY WITH RELIGIOUS VALUES OF MADRASAH ALIYAH STUDENTS
No full textThe limited integrated mathematics teaching materials focusing on discussing reasoning are one in learning mathematics problems, especially in preparation for integrated mathematics Olympiads. This study aimed to develop teaching materials for mathematical reasoning abilities integrated with religious values and students' attitudes towards mathematics integrating religious values. This research method is the ADDIE model development research method. At the implementation stage, the teaching materials were tested on research samples from MAN in the Regency and City of Sukabumi, with 76 students as research subjects. The sampling technique was purposive sampling—implemented through the Schoology application. The study results are as follows: teaching materials in integrated mathematical materials and questions to improve critical, creative, and adaptive reasoning skills towards religious values have good results and need to be developed more broadly than various materials with the separate presentation of mathematical material, teaching materials can improve critical, creative, and adaptive reasoning abilities with good results with an average score using module 60 and without module 52 with a maximum score of 100. Students' attitudes towards learning this integration method are in a suitable category. Integrated mathematics learning provides new experiences for students because learning mathematics is accompanied by learning to understand the contents of the Qur'an verses

PENGARUH MODEL MEANINGFUL INSTRUCTION DESIGN DENGAN PENDEKATAN RME TERHADAP HASIL BELAJAR MATEMATIKA MATERI PECAHAN
No full textMeaningful Instruction Design (MID) merupakan model pembelajaran yang mengutamakan kebermaknaan bagi siswa agar memudahkan siswa dalam mengingat kembali materi yang telah dipelajari. Alasan dilakukan penelitian ini dikarenakan studi pendahuluan yang mengatakan bahwa pembelajaran matematika masih disajikan secara abstrak, serta dengan model yang konvensional sehingga terkesan membosankan, serta kesulitan guru dalam menjelaskan materi matematika terutama pada materi pecahan. Hal ini tentunya berdampak pada perolehan hasil belajar. Maka dari itu, diperlukan pendekatan Realistic Mathematics Education (RME) berbasis kehidupan nyata yang akan memudahkan dalam menjelaskan pembelajaran matematika. Penelitian ini bertujuan untuk melihat pengaruh model MID dengan pendekatan RME terhadap hasil belajar matematika siswa. Penelitian ini menggunakan jenis praeksperimen dengan desain pretes dan postes satu grup. Teknik pengambilan sampel seacra bertujuan sebanyak 20 sampel dari total populasi sebanyak 23 siswa. Dari hasil perhitungan, rata-rata pretest dan postes siswa yaitu sebesar 22,762 yang memiliki kenaikan hasil belajar yang signifkan. Kemudian dari signifikansi yang diperoleh yaitu 0,00 2,086 (t tabel), sehingga dapat disimpulkan bahwa model MID dengan pendekatan RME memiliki pengaruh positif dalam peningkatkan hasil belajar matematika siswa materi pecahan
