Abstract

Jenis penelitian yang digunakan dalam penelitian ini adalah penelitian deskriptif kualitatif. Penelitian ini bertujuan untuk mendeskripsikan profil kemampuan pemecahan masalah matematika berdasarkan gaya kognitif field-dependent (FD). Penelitian ini dilaksanakan di SMPN 1 Kotabaru Semester ganjil Tahun Pelajaran 2020/2021. Subjek Penelitian yang diambil adalah siswa kelas VIIc yang berjumlah 1 siswa dengan gaya kognitif field-dependent (FD). Pengumpulan data dilakukan dengan menggunakan, angket gaya kognitif, tes tertulis, wawancara, dan dokumentasi. Adapun hasil penelitian  yang diperoleh terkait profil kemampuan pemecahan masalah matematika subjek adalah sebagai berikut: 1) pada tahap memahami masalah, subjek dapat memahami pernyataan verbal dari masalah, tetapi tidak dapat mengubahnya ke dalam kalimat matematika, hanya mengikuti informasi yang sudah ada. 2) Pada tahap membuat rencana penyelesaian, subjek sudah menuliskan langkah-langkah penyelesaian yang digunakan dengan benar. 3) pada tahap melaksanakan rencana, subjek dapat menyelesaikan masalah sesuai  dengan rencana yang telah dibuat, walaupun kurang terperinci karena masih terdapat langkah-langkah yang tidak dituliskan sampai didapatkan jawaban yang sebenarnya. 4) pada tahap melihat kembali, meskipun subjek sudah menyimpulkan jawaban dengan benar tapi subjek belum dapat membuktikan jawaban yang telah diperoleh. Kata Kunci: Gaya Kognitif, Pemecahan Masalah  Abstract The type of research used in this research is descriptive qualitative research. This study aims to describe the profile of mathematical problem solving abilities based on field-dependent (FD) cognitive style. This research was conducted at SMPN 1 Kotabaru in the odd semester of the 2019/2020 academic year. The research subjects taken were students of class VIIc, totaling 1 student with a field-dependent (FD) cognitive style. Data was collected using cognitive style questionnaires, written tests, interviews, and documentation. The research results obtained related to the profile of the subject's mathematical problem solving ability are as follows: 1) at the stage of understanding the problem, the subject can understand the verbal statement of the problem, but cannot convert it into mathematical sentences, only following the existing information. 2) at the stage of making a settlement plan, the subject has written down the steps of completion that are used correctly. 3) at the stage of implementing the plan, the subject can solve the problem according to the plan that has been made, although it is less detailed because there are still steps that are not written down until the real answer is obtained. 4) at the stage of looking back, even though the subject has concluded the answer correctly, the subject has not been able to prove the answer that has been obtained.

Abstract

This study aims to describe students' mathematical problem-solving ability in solving story problems. The type of research used in this study is qualitative descriptive research. This research was carried out at STKIP Paris Barantai KotaBaru. The research subjects taken were 2 students in semester V with low academic ability. The researcher chose the subject on the grounds that the student had received lecture material related to problem solving and what was found From the scores of the student's middle test and final test results, there were still students who obtained a score below 50.Data collection was carried out using written tests, interviews, and documentation. The results of the research obtained related to the subject's mathematical problem-solving ability are still very lacking, this can be seen from the 4 stages of problem-solving, namely: (1) For the stage of understanding the problem, the two research subjects in the first question seem to still have difficulty in understanding the problem; (2) For the stage of planning a settlement, both subjects apply certain strategies that are not appropriate; (3) For the stage of implementing the plan, there are still errors in the calculation operation process so it is wrong in finding answers; and (4) For the re-examination stage, S1 does not try to carry out this stage, while S2 tries to carry out the re-examination stage even though the answer results obtained are incorrect.
