No full textCreative reasoning is a person's ability to solve mathematical problems in a manner of thinking that deviates from the norm, yet remains logical and grounded in a strong mathematical foundation. While crucial for students, many have not yet attained proficiency in creative reasoning, necessitating comprehensive research on the subject. This study aims to elucidate students' creative reasoning abilities in tackling straight-line equation problems, focusing on indicators such as creativity, plausibility, and anchoring. Employing a qualitative approach with a case study design, the research involved three students from Madrasah Tsanawiyah who had studied straight-line equations. The primary instrument was the researcher, supported by a creative reasoning ability description test and interviews. Data collection utilized triangulation techniques, encompassing tests and interviews. Analysis of the research findings entailed describing students' creative mathematical reasoning abilities for each creative reasoning indicator in straight-line equation material. Results indicated that while students could provide correct and reasonable arguments in solving mathematical problems, they struggled to devise alternative methods and employ strategies based on mathematical concepts. Consequently, they only met the plausibility criterion, falling short in creativity and anchoring. Thus, it can be concluded that students have not yet achieved creative reasoning proficiency in solving straight-line equation problems.Penalaran kreatif adalah kemampuan seseorang dalam memecahkan masalah matematika dengan cara berpikir yang berbeda dari biasanya, namun proses penalarannya masuk akal dan mempunyai landasan matematika yang kuat.

LEARNING OBSTACLES ANALYSIS ON MULTIPLICATION OF NATURAL NUMBERS IN ELEMENTARY SCHOOL
No full textThis research aims to find learning obstacles students experienced during natural number multiplication lessons in third-grade elementary school. Learning obstacles were obtained from the Respondent Ability Test (RAT) analysis on students who had studied the lessons on multiplication of natural numbers. The method used in this research is a qualitative descriptive method. The subjects were respondents who participated in RAT, namely 22 third-grade elementary school students in Bandung, Indonesia. Data collection techniques use tests, interviews, and documentation. Data analysis techniques include data collection, reduction, display, and conclusion. Learning obstacles found in natural number multiplication lessons are categorized into three types, namely ontogenic, epistemological, and didactical obstacles. Ontogenic obstacles occur when there is a gap in the students' thinking when analyzing concrete to abstract concepts. Epistemological obstacles may occur if students need help to apply the concepts they have learned in the context of story problems. Didactical obstacles happen when the learning carried out by teachers is only procedural, so students only memorize each multiplication result. Therefore, it is essential to analyze these learning obstacles and find the causes as a reference in finding solutions to design future learning tools that prevent these learning obstacles from happening.Penelitian ini bertujuan untuk mengetahui hambatan belajar yang dialami siswa pada pembelajaran perkalian bilangan asli di kelas 3 SD. Hambatan belajar diperoleh dari hasil analisis Tes Kemampuan Responden (TKR) pada siswa yang telah mempelajari pembelajaran perkalian bilangan asli. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kualitatif. Subjek penelitian adalah responden yang mengikuti RAT, yaitu 22 siswa kelas 3 SD di Bandung, Indonesia. Teknik pengumpulan data menggunakan tes, wawancara, dan dokumentasi. Teknik analisis data meliputi pengumpulan data, reduksi, display, dan penarikan kesimpulan. Hambatan belajar yang ditemukan pada pembelajaran perkalian bilangan asli dikategorikan menjadi tiga jenis, yaitu hambatan ontogenik, epistemologis, dan didaktis. Hambatan ontogenik terjadi ketika terdapat kesenjangan dalam berpikir siswa ketika menganalisis konsep konkret ke abstrak. Hambatan epistemologis dapat terjadi ketika siswa membutuhkan bantuan untuk menerapkan konsep yang telah dipelajarinya dalam konteks soal cerita. Hambatan didaktis terjadi ketika pembelajaran yang dilakukan guru hanya bersifat prosedural, sehingga siswa hanya menghafal setiap hasil perkalian. Oleh karena itu, penting untuk menganalisis kendala pembelajaran tersebut dan mencari penyebabnya sebagai acuan dalam mencari solusi untuk merancang perangkat pembelajaran masa depan yang mencegah terjadinya kendala pembelajaran tersebut
