Abstract

Kemampuan pemecahan masalah matematis siswa di Indonesia masih tergolong rendah, dengan kecemasan matematis diidentifikasi sebagai salah satu penyebab utamanya. Penelitian ini bertujuan untuk menggambarkan kemampuan pemecahan masalah matematika siswa berdasarkan tingkat kecemasan matematisnya, menggunakan pendekatan kualitatif dengan metode studi kasus. Partisipan terdiri dari 39 siswa kelas XI dari sebuah SMA di Kota Serang, Provinsi Banten, yang telah mempelajari barisan dan deret geometri. Data dikumpulkan melalui tes tulis untuk mengukur kemampuan pemecahan masalah matematika serta menggunakan teknik non-tes seperti kuesioner kecemasan matematis dan wawancara. Hasil penelitian menunjukkan bahwa siswa dengan tingkat kecemasan matematis rendah memenuhi semua indikator kemampuan pemecahan masalah matematis, siswa dengan tingkat kecemasan matematis sedang memenuhi tiga dari empat indikator, dan siswa dengan tingkat kecemasan matematis tinggi hanya memenuhi satu dari empat indikator tersebut. Oleh karena itu, guru dan siswa harus mempertimbangkan strategi yang tepat untuk mengurangi kecemasan matematis dalam metode pembelajaran guna meningkatkan kemampuan pemecahan masalah matematis siswa.The mathematical problem-solving ability (MPSA) of students in Indonesia is low, with mathematical anxiety identified as a contributing factor. This research sought to explore students' MPSA from the perspective of mathematical anxiety levels using a qualitative approach with a case study method. The participants included 39 grade XI students from a senior high school in Serang City, Banten Province, who had learned arithmetic and geometric sequences. Data collection included written tests for MPSA and non-test techniques such as mathematical anxiety questionnaire and interviews. The results reveal that students with low mathematical anxiety level fulfilled all the indicators of MPSA, students with moderate mathematical anxiety level fulfilled three of the four indicators of MPSA, and students with high mathematical anxiety level only fulfilled one of the four indicators of MPSA. Therefore, teachers and students should consider appropriate strategies to reduce mathematical anxiety in learning methods, aiming to enhance students’ mathematical problem-solving ability.

Abstract

Logarithm has an important role in learning mathematics since various fields such as science, computer, finance, industry, and others are applied this material as one of the study subjects. In calculus, logarithm has an important role, especially natural logarithm. This study aims to determine pre-service mathematics teachers' difficulties in solving logarithm bases and numerus material. The subjects are students in the first semester in one university at Banda Aceh city who take elementary algebra course. The research was conducted with a descriptive approach to explain the difficulties that students faced, and it applied several steps such as providing logarithm test to students, determining the difficulties, and verifying it by interviewing students who had difficulties based on their answers. This study revealed that there were various difficulties that students faced such as; (1) lack of understanding of bases and numerus definitions of logarithms, (2) not being able to distinguish between expressions and logarithmic equations, (3) remembering too many formulas so that they do not understand the context of the problem, (4) couldn’t determine the position of irrational numbers on the number line.

Abstract

Mathematical reflective thinking ability is one of the higher-level abilities that can support other mathematical thinking skills. Therefore, ensuring students have good mathematical reflective thinking skills is essential. This study aimed to analyze students' mathematical reflective thinking skills (KBRMS) on the material of a two-variable linear equation system (SPLDV). This research approach is qualitative with a phenomenological type. Data collection techniques were carried out through reflective thinking skills tests and interviews. The study subjects were grade VIII junior high school students who had studied SPLDV material using purposive sampling techniques. Data analysis techniques in this study are data reduction, data display, conclusions, and verification. This mathematical reflective thinking ability analysis is based on indicators of mathematical reflective thinking ability, namely reacting, elaborating, and contemplating. The results of this study show that students can master reacting and elaborating indicators when faced with problems they usually encounter. In contrast, for contemplating indicators, students still experience difficulties when faced with problems different from those traditionally exemplified, such as difficulties in understanding problems and determining the concept of the material used. Based on this, it is shown that students' mathematical reflective thinking skills have not been fulfilled optimally.

Abstract

Understanding concepts in learning mathematics, especially triangles and quadrilaterals, is crucial. However, students often struggle with this material due to invalid and impractical teaching resources. This research aimed to develop valid and practical microlearning-based e-modules using a 3-D research model to improve students' understanding of triangles and quadrilaterals. Conducted at a junior high school in Sei Suka, Batu Bara Regency, North Sumatra Province, data were collected through interviews and questionnaires, utilizing instruments such as interview guides, expert validation sheets, and practicality test questionnaires. Data analysis included qualitative methods to reduce interview data and quantitative likert scale calculations. The developed e-modules were rated very valid by media and material experts and very practical by teachers. Testing on students showed that e-modules were quite practical on a small scale and very practical on a large scale. The effectiveness test revealed a significant improvement in students' understanding, with a gain score of 0.79, categorized as high. These results confirm that the microlearning-based e-module is valid, practical, and effective in enhancing students' understanding of triangles and quadrilaterals.        Keywords: E-modul, microlearning, triangle and quadrilateral. DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1244-1258

Abstract

Learning Obstacle  atau hambatan belajar pada pembelajaran matematika harus diminimalisir agar pembelajaran yang optimal dapat terwujud. Salah satunya yaitu pembelajaran pada materi Sistem Persamaan Linear Tiga Variabel (SPLTV). Penelitian ini bertujuan untuk untuk mengkaji dan mendeskripsikan hambatan belajar siswa pada pembelajaran materi SPLTV berdasarkan teori praxeology. Penelitian ini menggunakan pendekatan kualitatif dengan metode fenomenologi. Dengan menggunakan teknik triangulasi, penelitian ini menggunakan instrumen tes dan wawancara dalam mengidentifikasi hambatan belajar tersebut. Hasil analisis jawaban siswa dan wawancara mendalam berdasarkan teori praxeology menunjukkan bahwa siswa memiliki hambatan belajar, baik hambatan ontogenik, didaktik, maupun epistemologi. Hal tersebut digambarkan dengan ketidakmampuan siswa menggunakan teori dalam mendasari teknik penyelesaian, ketidaktepatan teori dan teknologi dalam mendasari teknik yang digunakan oleh siswa, dan ketidakmampuan siswa dalam memahami jenis tugas yang diberikan. Ketiga hambatan yang teridentifikasi berdasarkan praxeologydiharapkan dapat menjadi acuan bagi guru untuk dapat menyusun bahan ajar yang dapat meminimalisir hambatan belajar pada siswa.Learning Obstacles or learning barriers in learning mathematics must be minimized so that optimal learning can be realized. One of them is learning on the Three Variable Linear Equation System (SPLTV) material. This study aims to examine and describe student learning obstacles in learning SPLTV material based on praxeology theory. This research uses a qualitative approach with phenomenological method. By using triangulation techniques, researchers used test instruments and interviews to identify these learning barriers. The results of the analysis of student answers and in-depth interviews based on praxeology theory show that students have learning barriers, both ontogenic, didactic, and epistemological barriers. This is illustrated by the inability of students to use theory to underlie the completion technique, the inaccuracy of theory and technology in underlying the techniques used by students, and the inability of students to understand the type of assignments given. The three obstacles identified based on praxeology are expected to be a reference for teachers to be able to develop teaching materials that can minimize learning barriers to students.
