Abstract

AbstractMathematical Creative Thinking Ability (MCTA) is a crucial skill for students in their mathematics learning. However, limited research exists on the inhibiting factors of Mathematical Creative Thinking (MCT), specifically among junior high school students. Therefore, this study aims to explore these inhibiting factors among junior high school students using a qualitative method with a case study approach. Data were collected through assignment tasks, observations, and interviews, wherein the tasks were designed as open-ended questions. The study identified themes generated from the data analysis, revealing several factors inhibiting students’ MCT. These factors include negative perceptions towards mathematics and its learning, intrinsic motivation, inadequate understanding of basic concepts, the experience of learning loss, low self-efficacy towards open-ended questions, low procedural understanding of open-ended questions, and insufficient teacher competence.Keywords: Mathematical creative thinking, school mathematics, open-ended problem, case study.AbstrakKemampuan berpikir kreatif matematis (KBKM) adalah kemampuan esensial yang harus dimiliki siswa pada pembelajaran Matematika. Akan tetapi, belum banyak penelitian yang membahas faktor penghambat berpikir kreatif matematis (BKM) siswa menengah pertama. Oleh karena itu, penelitian ini bertujuan untuk mengeksplorasi faktor penghambat BKM siswa menengah pertama. Penelitian ini menggunakan metode kualitatif dengan pendekatan studi kasus. Data dikumpulkan melalui pemberian tugas, melakukan pengamatan, dan melakukan wawancara. Tugas yang dikerjakan oleh partisipan adalah tipe soal open-ended. Temuan pada penelitian ini merupakan tema-tema yang dihasilkan dari analisis data. Berdasarkan temuan yang diperoleh, faktor-faktor yang menghambat BKM siswa adalah memiliki persepsi negatif terhadap Matematika dan pembelajarannya, motivasi intrinsik, pemahaman konsep dasar yang rendah, mengalami learning loss, efikasi diri yang rendah terhadap soal open-ended, pemahaman prosedural yang rendah terhadap soal open-ended, dan kompetensi guru yang kurang memadai.Kata kunci: Berpikir kreatif matematis, Matematika sekolah, soal open-ended, studi kasus.

Abstract

Mathematics researchers and educators promoted problem-solving as an essential process and skill for every student, as it was closely related to the development of students’ mathematical abilities and necessary for solving problems they encountered, both at that time and in the future. Several studies indicated that Indonesian students’ mathematical problem-solving skills remained low. This study focused on 8th-grade students at a public middle school in Tarakan, North Kalimantan, who were struggling with mathematical problem-solving. The study aimed to describe the mathematical problem-solving process carried out by the students in the 8th-grade class. Using a case study qualitative strategy, the researcher collected data through assignments, observation, document analysis, and interviews. Data analysis followed the model by Miles et al. (2014), which included data condensation, data display, and drawing conclusions and verification. The findings revealed that students’ mathematical problem-solving processes involved three main themes: understanding the problem, problem-solving strategies, and answer verification. Additionally, two supplementary themes were identified: students’ attention while facing problems and their perceptions of the mathematical problem and the provided solution. These findings highlighted the importance of educational practices that strengthened problem-solving through instruction and enhanced their self-regulation when dealing with mathematical problems.Keywords: mathematics, problem-solving, Polya, word problems. AbstrakPeneliti dan pendidik matematika mempromosikan pemecahan masalah sebagai proses dan keterampilan esensial bagi setiap siswa karena berkaitan erat dengan perkembangan kemampuan matematis siswa tersebut, dan dibutuhkan untuk memecahkan masalah matematis yang dihadapi, baik di masa sekarang maupun di masa depan.
