Abstract

The aim of the research is to describe the results of designing number pattern questions used to measure the mathematical thinking abilities of students with a kinesthetic learning style. The research subjects consisted of 5 class VIII students with a kinesthetic learning style. The type of research is design research with 5 stages, namely: Preliminary Design, Focus Group Discussion (FGD), Trial, Interview, and Retrospective Analysis. The data collection techniques are learning style questionnaires, tests and interviews. The data analysis used in the research is qualitative. Based on the results of the FGD, number pattern questions can be used to measure mathematical thinking abilities, because each question leads students to bring up specializing, generalizing, conjecturing and convincing aspects. Based on the test results, it is known that students can write specializing, generalizing, conjecturing, and convincing forms. Specializing is seen when students write the form of adding numbers for each term. Generalizing is seen when students find patterns by listing them one by one or using tables, conjecturing when they find the general formula, and convincing is seen when they find other ways to prove the answer. Based on the results of the interview, students' answers were obtained through the activity of managing and simulating questions using body parts.

Abstract

The low level of mathematical literacy among Indonesian students is reflected in the average results of PISA 2022, indicating the need to develop PISA-style test instruments. Therefore, this study aims to develop PISA-based questions on numbers that are valid and reliable. The method used is a development study consisting of preliminary and formative evaluation stages. The preliminary stage includes analyzing original PISA questions, student needs, curriculum, and determining the material. The formative evaluation stage includes self-evaluation, expert review, one-on-one, and small group discussions. The format of the questions developed is two multiple-choice questions and four contextual descriptions equivalent to PISA. Content validation was tested qualitatively through expert comments, while quantitative analysis was conducted after testing the questions on six junior high school students in Palembang who were selected purposively. Quantitative analysis includes item validity, reliability, difficulty level, and discriminative power. The research results indicate that the questions are valid and reliable based on content appropriateness, ease of understanding, smooth implementation, and time efficiency. These questions can be used as a training tool to improve students' mathematical abilities in accordance with PISA standards. However, this study has limitations due to the limited sample size and only reaching a small group, so it is recommended that further research be conducted with a larger sample size and up to the field test stage.

Abstract

Background: Students often face difficulties in geometry learning, especially in topics that require students to interpret spatial objects and transform visual information into mathematical procedures including polyhedral geometry. Purpose: This study aims to analyze students’ mathematical problem-solving based on Polya’s framework in polyhedral geometry tasks within a GeoGebra Augmented Reality (AR)-supported. Method: This study used a mixed-method involving 30 eighth-grade students in Prabumulih. Data were collected through a mathematical problem-solving test, interviews, and classroom observation. Students’ responses were analyzed using a scoring rubric based on four stages of Polya’s problem solving: understanding the problem, devising a plan, carrying out the plan, and looking back. Findings: Most students fell into the medium problem-solving category (63.3%), with only 10% achieving the high category. While students performed best in understanding the problem, their primary difficulties lay in devising a plan and looking back. Implications: The integration of GeoGebra AR supports students in visualizing three-dimensional objects concretely. However, visual support alone is not sufficient to ensure complete problem-solving performance. Originality: The contribution of this study lies in a stage-by-stage diagnostic profile of students’ mathematical problem-solving in polyhedral geometry within a GeoGebra AR-supported learning environment.

Abstract

The strengthening of psychological literacy and early detection of students’ mental health in the school environment is especially important for adolescents who face academic, social, and boarding-school adjustment pressures. SMP Advent Palembang was selected as a partner because it needed a simple yet effective instrument to help teachers and dormitory supervisors understand students’ emotional conditions. This community service activity aimed to improve teachers’ understanding of psychological literacy and to assist in the development and implementation of the Emotion Reflection Sheet (Lembar Refleksi Emosi/LRE) as a tool for the early detection of students’ mental health issues. The implementation method included the stages of preparation, training, mentoring, implementation, and evaluation. The activities were carried out through lectures, discussions, instrument-development practice, and assistance in using the LRE in both printed and digital forms. The results showed that participants experienced improved understanding of psychological literacy, emotion regulation, and the importance of students’ emotional reflection. This program also produced outputs in the form of an Emotion Reflection Sheet and a simple dashboard to monitor students’ emotional patterns periodically. These findings indicate that the use of a simple reflective instrument can support the creation of a school culture that is more empathetic, responsive, and concerned with students’ psychological well-being.

Abstract

Matematika sosial dan numerasi merupakan kompetensi esensial yang harus dimiliki oleh siswa agar dapat berpartisipasi secara aktif dalam kehidupan bermasyarakat. Namun, hasil observasi awal menunjukkan masih banyak guru SMP yang menghadapi kesulitan dalam mengintegrasikan pendekatan Pendidikan Matematika Realistik Indonesia (PMRI) ke dalam proses pembelajaran. Permasalahan yang dihadapi adalah rendahnya kemampuan guru dalam mengaitkan konsep matematika dengan konteks sosial dan budaya siswa, terbatasnya referensi pembelajaran berbasis numerasi kontekstual, serta belum terbentuknya komunitas belajar yang secara aktif mendukung penerapan norma matematika sosial di sekolah. Norma sosial dan numerasi yang digunakan berkonteks budaya Palembang yaitu makanan tradisional Palembang dan kain tradisional Palembang. Kegiatan dilaksanakan synchronous dan asynchronous dengan melibatkan 32 orang guru dari berbagai SMP di Kota Prabumulih. Kegiatan ini mencakup pelatihan, diskusi kelompok, dan pendampingan secara dalam mendesain konteks budaya lokal, seperti makanan tradisional dan kain songket Palembang. Hasil analisis pre-test dan post-test menunjukkan peningkatan kompetensi guru dengan nilai sebesar 0,714 serta respon peserta yang positif terhadap kegiatan. Temuan ini menunjukkan bahwa pendekatan komunitas belajar PMRI efektif dalam memperkuat norma matematika sosial dan numerasi.

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.
