Abstract

Students' problem-solving skills remains a challenge because mathematics instruction often emphasizes procedures over creativity and rarely incorporates students' cultural contexts. This study explores the impact of Project-Based Culturally Responsive Teaching (CRT) on students' creative thinking and problem- solving skill, as well as teacher's perceptions of cultural integration in mathematics instruction. This explanatory sequential design study involved a class of 15 eighth- grade students and a mathematics teacher. Data were collected through observations, project assignments, tests, and questionnaires. The results showed that students' creative thinking indicatorsfluency, flexibility, and originalitywere in the excellent category, while elaboration increased from 79.17 (good) to 87.5 (excellent). Furthermore, there was a significant improvement in students' problem- solving skills, with an average pre-test score of 49.33 increasing to 64.33 (p < 0.05). The teacher responded that project-based CRT helped students develop more effective problem-solving strategies. These findings suggest that project-based CRT can foster students' creative thinking and problem-solving skill in mathematics. Teachers are encouraged to design problem-solving activities that connect mathematical concepts to students' cultural experiences to foster deeper understanding and more equitable learning opportunities

Abstract

Discovery learning is a learning model that is useful for developing students' mathematical reasoning skills. This research aims to develop E-LKPD based on discovery learning that are valid, practical, and effective. This research uses the ADDIE approach (Analysis, Design, Development, Implementation, and Evaluation). Product testing carried out included limited field trials to 10 students and extensive field trials to 24 students of SMP Negeri 1 Gondanglegi, Malang Regency. Data collection techniques utilize expert validation sheets, E-LKPD practicality questionnaires, and mathematical reasoning test sheets. The product validity tests conducted by experts (material, learning, and media experts) are declared valid with a score of 3.44. The product practicality test's results based on student responses obtained a score of 3.42 so it’s declared practical. The product effectiveness test's results obtained a completeness percentage of 70.8% and declared effective in learning activities. Students' reasoning ability is said to improve based on their test results. This study concludes that the E-LKPD based on Discovery Learning is valid, practical, and effective and can improve the students’ mathematical reasoning ability. It’s hoped that the E-LKPD developed used as mathematics teaching materials.

Abstract

Mathematics is one of the subjects that is considered difficult, boring, and the use of mathematics learning media in schools is still less than optimal due to limited media and time. This study aims to develop learning media based on local wisdom on snakes and ladders with valid, feasible, and effective question cards to improve students' reasoning. The study uses the ADDIE development model (Analysis, Design, Development, Implementation, Evaluation). The instrument uses a validation sheet, a response questionnaire, and reasoning test questions. The developed media was tested in a limited field trial involving 6 students of class VIIA and a large field trial involving 25 students of class VIIB at SMP Diponegoro Tumpang. The validity was obtained from the validation results, the feasibility was obtained from the response questionnaire, and the effectiveness was obtained from the results of the students' reasoning test. The validation results showed very high validity. The feasibility results were very feasible, namely, in the limited field obtained a result of 3.79 and in the large field, 3.31 which means media. The effectiveness results were very effective, namely, the test question score in the large field test was 95.6%. Based on the research results, it can be concluded that the local wisdom-based learning media, snakes and ladders, developed is very valid, very feasible, and very effective for use in learning and can improve students' reasoning. It is hoped that the local wisdom-based learning media, snakes and ladders, with question cards, can be used in mathematics learning.

Abstract

Kemampuan penalaran dan koneksi matematis dalam pemecahan masalah matematika merupakan kecakapan penting untuk dikuasai oleh mahasiswa, sehingga mampu menyelesaikan masalah matematika secara bernalar dan mampu untuk mengaitkan antar konsep matematis. Penelitian ini menggunakan pendekatan kualitatif yang bersifat naturalistik, dengan rancangan penelitian tindakan kelas, yang dilaksanakan dalam dua siklus. Subjek penelitian yaitu mahasiswa program studi pendidikan matematika yang menempuh matakuliah fungsi kompleks. Pengambilan data dilakukan dengan observasi, tes, dokumentasi, catatan lapangan. Data dianalisis mulai awal tindakan pembelajaran dan dilakukan refleksi hingga penyusunan laporan, dengan analisis data yaitu kualitatif deskriptif yang meliputi reduksi data, penyajian data, menelaah data dan penarikan kesimpulan (verifikasi). Keabsahan data dengan menggunakan triangulasi. Tujuan penelitian untuk mendiskripsikan kemampuan penalaran dan koneksi matematis dalam pembelajaran matematika dengan problem solving. Hasil penelitian menunjukan bahwa terjadi peningkatan kemampuan penalaran dan koneksi matematis dalam pembelajaran matematika dengan problem solving.

Abstract

Kemampuan spasial merupakan salah satu kompetensi penting dalam pembelajaran matematika, khususnya pada materi bangun ruang. Namun, pembelajaran masih didominasi penggunaan bahan ajar konvensional sehingga kurang mendukung pengembangan kemampuan spasial peserta didik. Salah satu alternatif yang dapat diterapkan adalah e-modul bermuatan etnomatematika berbasis Candi Prambanan yang mengintegrasikan konsep matematika dengan budaya lokal melalui media pembelajaran interaktif. Penelitian ini bertujuan menganalisis efektivitas e-modul bermuatan etnomatematika berbasis Candi Prambanan dalam meningkatkan kemampuan spasial siswa kelas VIII SMP. Penelitian menggunakan pendekatan kuantitatif dengan metode quasi-experimental dan desain nonequivalent control group design. Sampel ditentukan menggunakan teknik cluster random sampling, sehingga diperoleh 30 siswa kelas VIII B sebagai kelas eksperimen dan 30 siswa kelas VIII D sebagai kelas kontrol. Data dikumpulkan menggunakan enam soal uraian kemampuan spasial dan dianalisis melalui uji validitas, reliabilitas, normalitas, homogenitas, N-Gain, serta Independent Samples t-test berbantuan IBM SPSS Statistics 22. Hasil penelitian menunjukkan bahwa instrumen valid dan reliabel dengan nilai Cronbach's Alpha sebesar 0,632. Hasil uji hipotesis memperoleh nilai signifikansi 0,000 (< 0,05), sehingga terdapat pengaruh yang signifikan penggunaan e-modul bermuatan etnomatematika terhadap peningkatan kemampuan spasial siswa. Rata-rata N-Gain kelas eksperimen sebesar 0,6396 (kategori sedang) lebih tinggi dibandingkan kelas kontrol sebesar 0,2302 (kategori rendah). Dengan demikian, e-modul bermuatan etnomatematika berbasis Candi Prambanan efektif digunakan untuk meningkatkan kemampuan spasial siswa pada materi bangun ruang.
