Abstract

Penelitian ini dilakukan untuk mendeskripsikan kemampuan penalaran matematis pada siswa kelas VII MTs. Raudlatul Ulum Putri Ganjaran saat menyelesaikan soal materi segiempat. Penelitian ini melibatkan 13 siswa di kelas VII E dan menggunakan pendekatan deskriptif kualitatif. Penelitian ini menggunakan instrumen soal materi segiempat yang terdiri dari satu soal dengan empat indikator penalaran matematis sebagai alat pengumpulan data. Hal ini memungkinkan untuk mengetahui lebih lanjut tentang cara siswa menyelesaikan setiap pertanyaan dan memberikan gambaran umum tentang kemampuan penalaran mereka. Hasil penelitian diperoleh data bahwa siswa kategori kemampuan penalaran baik dapat memenuhi empat indikator kemampuan penalaran matematis, siswa kategori kemampuan penalaran cukup hanya dapat memenuhi tiga dari empat indikator kemampuan penalaran matematis yakni menuliskan dugaan, menuliskan manipulasi matematika dan memberikan alasan terhadap solusi yang diberikan. Siswa kategori kemampuan penalaran kurang hanya dapat memenuhi dua dari empat indikator kemampuan penalaran matematis yakni menuliskan dugaan dan menuliskan manipulasi matematika. Dengan upaya yang terarah dan berkelanjutan, diharapkan dapat membantu siswa kelas VII MTs. Raudlatul Ulum Putri Ganjaran dalam mengembangkan kemampuan penalaran matematis mereka dan meningkatkan kemampuan mereka untuk menyelesaikan soal-soal matematika dengan lebih baik.

Abstract

This study describes the profile of students' mathematical reasoning ability in solving arithmetic rows and series problems. Based on the results of observations and interviews with the mathematics teacher of class X SMK Ma'wataibin Pagelaran Malang, information was obtained that 83% of students in the class tended not to be able to conclude the answer. This descriptive research uses a qualitative approach. The sample of this research is 19 students of class X SMK Ma'wataibin Pagelaran. They then selected one each in the high, medium, and low-level categories. Then, interviews were conducted with each subject to explore deeper information. The test instrument used is 1 question that contains four indicators of mathematical reasoning ability. The test results obtained that students in the high mathematical reasoning ability category amounted to 7 students, with a percentage of 36.85%. Students in the moderate mathematical reasoning ability category amounted to 8 students, with a rate of 42.10%. Students in the low mathematical reasoning ability category amounted to 4 students, with a rate of 21.05%. Based on the results of the data analysis, it is shown that high-category students fulfill four indicators of reasoning ability according to their abilities. Medium-category students correctly fulfill three indicators of mathematical reasoning ability: writing conjectures, doing work, and providing reasons/evidence. Low-category students only fulfill one indicator of mathematical reasoning ability, namely writing conjectures.
