The cognitive and affective abilities needed in this modern era are numeracy literacy and self-regulated learning (SRL). Based on the results of preliminary research conducted at a public junior high school in the Cijantung area on the material of comparison of value and reciprocal value, the three indicators of numeracy literacy were still below 50% and the average percentage of SRL success only reached 45.75%. Students' numeracy literacy and SRL abilities are influenced by the learning resources, media, and learning approaches used. Therefore, it is necessary to develop PMRI-based teaching materials through liveworksheets. The purpose of this study is to produce a product in the form of teaching materials using PMRI-based liveworksheets on the material of comparison of value and reciprocal value. This study was conducted in the even semester of the 2024/2025 academic year. The sample used consisted of 36 seventh grade students. The type of research used was R&D with the ADDIE model. Data analysis used the pre-test post-test control group method which was used to test the effectiveness of the product. The results of the study showed that the developed product was categorized as very valid (93,79%) based on expert assessments consisting of material aspects (89,93%), media (96,44%), and language (95,00%). The developed product was very practical (88,985) based on teacher responses (89,58%) and students (88,68%). Through n-gain calculations, this teaching material was effective in improving numeracy literacy skills to the high category (0,8) but could only improve SRL to the moderate level (0,46).

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.

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.

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.
