Abstract

Mathematical problem-solving skills are a key competency of the 21st century and are an important focus in mathematics education. This study aims to map the development of research on mathematical problem-solving skills in the period 2010–2025 using a bibliometric approach based on Google Scholar. Data were collected through Harzing's Publish or Perish (PoP) using keywords related to mathematical problem solving/problem solving ability and exported in .CSV and .RIS formats. The metadata were then cleaned and normalized using Microsoft Excel, then analyzed using VOSviewer to produce network, overlay, and density visualizations. The results of the analysis show an increasing publication trend since 2015, peaking in 2021–2022, then declining in 2023–2025, which is thought to be influenced by the limited coverage of current data. Co-occurrence mapping formed several main clusters: (1) learning models and problem-solving development, (2) skills/abilities as learning outcomes, (3) educational context and learning influences, (4) problem-solving processes and strategies as well as affective factors (self-efficacy), and (5) assessment and ability indicators. The overlay findings indicate that current topics for 2021–2025 are shifting toward affective factors and self-regulation, such as self-efficacy, mathematical resilience, independence, and the study of strategies and processes. Overall, research is still dominated by cognitive and pedagogical factors, while integrative exploration of affective aspects and the development of comprehensive assessment instruments remain limited. This mapping provides a basis for formulating directions for further research and strengthening the design of learning and assessment of mathematical problem-solving skills.

Abstract

ABSTRACT: Numeracy is a crucial competence for students to apply mathematics in real-life situations. This study aims to comprehensively profile the numeracy skills of junior high school students, considering the existing gap between the importance of numeracy and students' actual proficiency in the field. The research method employed was descriptive research with a quantitative approach. This study involved a sample of 33 eighth-grade students at SMPN 71 Jakarta. The instrument used was a two-item essay test designed to measure three key indicators: (1) the application of number concepts, (2) the analysis of visual information, and (3) the interpretation of results for drawing conclusions. The collected data were analyzed using descriptive statistics. The results indicate that the students' numeracy skills are at a very concerning level, with an average score of only 6.36 out of a maximum score of 20. These findings can provide a strong data foundation for educators to design more targeted learning interventions.   ABSTRAK: Kemampuan numerasi merupakan kompetensi krusial bagi siswa untuk mengaplikasikan matematika dalam kehidupan nyata.

Abstract

This study aims to describe students' mathematical problem-solving abilities based on their self-confidence levels through Problem Based Learning (PBL) with a Realistic Mathematics Learning (RMAT) approach. This study used a descriptive qualitative approach with nine tenth-grade students selected purposively based on the results of a self-confidence questionnaire, problem-solving ability test results, observations, and interviews. The results showed that students with high self-confidence tended to be able to solve problems completely and systematically according to Polya's steps. Students with moderate self-confidence showed quite good abilities, but were not consistent in re-checking their answers. Meanwhile, students with low self-confidence experienced difficulties from understanding the problem to solving it. The PBL learning process with the RMAT approach was proven to help students relate mathematical concepts to real contexts, build self-confidence, and increase active involvement in the problem-solving process.

Abstract

Penelitian ini bertujuan untuk menganalisis secara sistematis efektivitas e-modul interaktif berbasis Problem Based Learning (PBL) dalam meningkatkan Higher Order Thinking Skills (HOTS) peserta didik pada berbagai jenjang pendidikan. Permasalahan utama yang diangkat adalah rendahnya kemampuan berpikir tingkat tinggi dalam pembelajaran konvensional yang belum optimal memanfaatkan teknologi digital sebagai sarana pembelajaran aktif dan reflektif. Penelitian ini menggunakan desain Systematic Literature Review (SLR) dengan pendekatan deskriptif analitis, mengikuti panduan PRISMA 2020. Data sekunder dikumpulkan dari 18 artikel ilmiah terpublikasi pada periode 2020-2025 melalui basis data Scopus, ERIC, ScienceDirect, SpringerLink, dan Google Scholar. Pemilihan artikel dilakukan menggunakan teknik purposive sampling dengan kriteria kesesuaian topik, desain penelitian, dan relevansi terhadap variabel yang dikaji. Analisis data dilakukan secara tematik dan kuantitatif deskriptif, menggunakan Microsoft Excel dan NVivo 14 untuk mengidentifikasi pola dan tren penelitian. Hasil analisis menunjukkan bahwa penggunaan e-modul interaktif berbasis PBL berpengaruh signifikan terhadap peningkatan HOTS dengan rata-rata peningkatan 24,8% (SD = 7,6%) dan nilai effect size Cohen’s d = 0,84, yang tergolong tinggi. Fitur e-modul yang paling berkontribusi adalah interaktivitas dinamis, umpan balik otomatis, dan simulasi kontekstual. Temuan ini mendukung hipotesis bahwa pembelajaran berbasis masalah dengan dukungan media interaktif mampu mengembangkan kemampuan analisis, evaluasi, dan kreasi peserta didik. Secara teoretis, penelitian ini memperkuat pendekatan konstruktivis dan teori pembelajaran multimedia, serta memberikan implikasi praktis bagi pengembangan kurikulum digital dan peningkatan kompetensi guru dalam desain pembelajaran abad ke-21.

Abstract

This study was motivated by the low level of critical thinking skills among junior high school students in solving mathematical word probleims, as evident from previous studies and the researcher's initial observations in the field. This study aims to describe the profil of junior high school students' errors in solving mathematical story problems in terms of critical thinking skills. The method used is qualitative descriptive with 32 seventh-grade students as subjects at a public junior high school in South Tambun in the 2024/2025 academic year. The research instrument was an essay test containing five story problems developed based on critical thinking ability indicators, including providing simple explanations, providing further explanations, determining strategies and techniquies, and drawing conclusions. The data were analyzed through the stages of reduction, presentation, and conclusion drawing. The results showed that most students were in the low critical thinking ability category (63%) and the rest were in the moderate category (37%), while no students reached the high category. Students with low critical thinking abilities tended to make mistakes in almost all indicators, while students with moderate abilities were able to meet most of the indicators but were not consistent, especially in determining solution strategieis and drawing conclusions. These findings indicate that the main weakness of students lies in the aspects of strategy planning and drawing conclusions, so mathematics learning that emphasizes the development of critical thinking skills through non- routine story problems and the use of targeted assessment rubrics is needed.

Abstract

This study aims to identify students’ misconceptions in solving Higher Order Thinking Skills (HOTS) geometry problems on plane figures. A descriptive qualitative approach using Cognitive Error Analysis was applied to the written responses of 10 eleventh-grade students in the Mathematics Cambridge Program. The validated instrument consisted of three HOTS essay items. Data were analyzed through error classification, mapping to HOTS levels (C4, C5, C6), and in-depth diagnosis of responses identified as misconceptions. The findings show that students’ main difficulties lie in the Analyzing stage (C4), which subsequently weakens their ability to evaluate and create strategies (C5–C6). Two dominant patterns emerged: misreading non-routine instructions and errors in fundamental geometric concepts, with several cases indicating independent weaknesses at C6. These results highlight the need to strengthen strategic analysis as the foundation for HOTS development. The study is limited by its small sample size and reliance on written data.

Abstract

Mathematical communication skills are fundamental competencies that need to be developed from the junior high school level; however, evaluation instruments specifically designed to measure these skills remain scarce. This study aimed to develop a contextual learning-based test instrument to measure the mathematical communication skills of seventh-grade junior high school students on algebra material. This study employed a research and development approach, encompassing stages of blueprint construction, expert validation by three mathematics education lecturers, and a field trial involving 35 seventh-grade students of SMPN 1 Citeureup as trial subjects, selected through purposive sampling. Data were analyzed using Pearson correlation, Cronbach's Alpha, discrimination power test, and difficulty level test through SPSS 25. The results indicate that the developed instrument is valid and reliable, and is therefore suitable for measuring students' mathematical communication skills. Nevertheless, several items still require revision in terms of discrimination power and difficulty level in order to make the instrument more optimal in fostering the improvement of junior high school students' mathematical communication skills. ABSTRAK Keterampilan komunikasi matematis merupakan kompetensi fundamental yang perlu dikembangkan sejak jenjang SMP, namun ketersediaan instrumen evaluasi yang dirancang secara spesifik untuk mengukur keterampilan tersebut masih sangat terbatas. Penelitian ini bertujuan mengembangkan instrumen tes berbasis pembelajaran kontekstual untuk mengukur keterampilan komunikasi matematis siswa SMP kelas VII pada materi aljabar. Penelitian ini menggunakan pendekatan penelitian dan pengembangan (research and development) yang mencakup tahapan penyusunan kisi-kisi, validasi ahli oleh tiga dosen Pendidikan Matematika, dan uji coba lapangan yang melibatkan 35 siswa kelas VII SMPN 1 Citeureup sebagai subjek uji coba yang dipilih menggunakan teknik purposive sampling. Data dianalisis menggunakan korelasi Pearson, Cronbach's Alpha, uji daya pembeda, dan uji tingkat kesukaran melalui aplikasi SPSS 25. Hasil penelitian menunjukkan bahwa instrumen yang dikembangkan bersifat valid dan reliabel sehingga layak digunakan untuk mengukur keterampilan komunikasi matematis siswa. Meskipun demikian, beberapa butir soal masih memerlukan revisi pada aspek daya pembeda dan tingkat kesukaran agar instrumen menjadi lebih optimal dalam mendorong peningkatan keterampilan komunikasi matematis siswa SMP.
