Abstract

Character education plays an important role in shaping individuals who not only excel academically but also possess strong morals and high social values. In the context of mathematics learning, character values not only help students understand numerical concepts but also instill discipline, hard work, and perseverance. This study aims to analyze the implementation of character values in mathematics learning and the role of teachers in developing them. The subjects of the study were 100 high school students from public schools in Palembang. Data were collected through questionnaires and interviews and analyzed using descriptive methods. The results showed that the values of discipline, hard work, and religiosity were dominant, while creativity and communication remained weak. Therefore, efforts are needed to develop these values, particularly creativity and communication, through improved teacher professionalism, interactive learning, integration of real-world contexts, and addressing students' psychological barriers.

Abstract

This study aims to develop the Magic Cube, an innovative manipulative learning medium designed to improve students’ conceptual understanding of number patterns. Number patterns are essential for building mathematical reasoning and problem-solving skills, yet many students struggle due to abstract teaching methods that lack interactive components. Previous studies have highlighted the effectiveness of game-based learning, but there remains a research gap in developing tangible and engaging media that directly support students’ comprehension. To address this, the study applied a Research and Development (R&D) approach using the ADDIE model, consisting of five stages: analysis, design, development, implementation, and evaluation. The Magic Cube, designed as a three-dimensional cube equipped with material and question cards, was validated by two media experts and two material experts, achieving validity scores of 86% and 73%. Practicality tests involving teachers and students resulted in scores of 84.83% and 86.6%, respectively. Furthermore, pre-test and post-test results showed a significant improvement in students’ conceptual understanding, with an N-Gain score of 0.7, categorized as high. These findings indicate that the Magic Cube is a valid, practical, and effective instructional tool. The study contributes to enhancing interactive mathematics learning and provides broader implications for fostering active engagement and improving students’ comprehension of abstract mathematical concepts.

Abstract

Walaupun telah banyak penelitian yang membahas kemampuan literasi matematika dalam menyelesaikan soal-soal PISA, konten uncertainty and data masih jarang dijadikan fokus utama. Penelitian ini bertujuan mengisi kekosongan tersebut dengan menganalisis secara mendalam terhadap pola berpikir serta strategi yang digunakan oleh siswa dalam mengerjakan soal-soal PISA yang berfokus pada konten uncertainty and data. Pendekatan penelitian yang digunakan adalah kualitatif deskriptif, dengan melibatkan tiga orang siswa sekolah menengah atas di Kota Palembang yang dipilih melalui teknik purposive sampling berdasarkan variasi tingkat kemampuan matematika. Data dikumpulkan melalui tes tertulis dan wawancara mendalam, kemudian dianalisis dengan mengaju pada tiga indikator literasi matematika dari OECD, yaitu formulate, employ, dan interpret. Hasil analisis menunjukkan bahwa siswa yang memiliki kemampuan matematika tinggi umumnya mampu memenuhi hampir semua indikator tersebut. Di sisi lain, siswa dengan tingkat kemampuan sedang umumnya hanya dapat memenuhi dua indikator, sementara siswa dengan kemampuan rendah tidak menunjukkan pencapaian berarti pada indikator manapun. Indikator formulate tampak sebagai aspek yang paling menantang bagi sebagian besar peserta didik. Temuan ini menegaskan pentingnya penguatan kemampuan literasi matematis, khususnya dalam merumuskan masalah dari konteks nyata, guna meningkatkan kualitas pembelajaran matematika di sekolah.

Abstract

This study aims to analyze the forms of metacognitive errors made by junior high school students in solving questions developed by the Programme for International Student Assessment (PISA) on number content. Metacognitive skills are part of a higher-order thinking process that includes awareness and control of one's own thinking process, including strategy planning, monitoring implementation, and evaluating results. In the context of PISA-like math problem that require contextual and complex problem solving, these skills are crucial. This study employed a qualitative approach using a case study design. The research subjects consisted of three VIII grade students who were identified according to the categories of high, medium, and low mathematical ability. The main instruments were PISA-like math problem and interview guidelines based on metacognitive indicators. Data were obtained using written assessments and comprehensive interviews, then examined through qualitative descriptive analysis. The results showed that all students, regardless of mathematics ability level, made metacognitive errors. The most dominant errors occurred at the planning and evaluation stages. Students with low ability had difficulty understanding the problem, identifying relevant information, and designing a solution strategy. While students with medium and high abilities tend not to evaluate steps and results optimally. The results underscore the significance of enharing metacognitive abilities in mathematics education to foster reflective thinking and tackle complex problems.

Abstract

This study aimed to develop a mathematics learning tool called “Pizza for Circles” to help students better understand the concept of circles. Students often memorize formulas without grasping the underlying concepts, particularly the area and circumference of a circle, which is the problem this study addresses. A research and development method was used to create manipulative and visual media supported by a website as a learning aid. This media presents a circle as a pizza divided into eight slices, illustrating the relationships among its components. A one-group pretest–posttest design was applied to a small group of three seventh-grade students. The media was validated by two experts, achieving 98.75% for material content and 86.4% for media design, both of which fall in the highly valid category. A small-group trial with the same three students showed a descriptive increase in the mean score from 2.0 to 5.83 out of 10 after a single-session intervention, corresponding to a normalised gain of 0.48 (medium category). Because the sample was very small, the results were not tested inferentially; nevertheless, they indicated an improvement in students’ understanding, as evidenced by higher post-test scores than pre-test scores. These results suggest that the “Pizza for Circles” media can aid in the initial understanding of circle concepts through a visual and manipulative approach. Further research with a larger sample and a longer learning period is nevertheless required before any claim of effectiveness can be made.
