Abstract

Teacher-centered mathematics learning and teaching materials that do not support contextual problems cause a low level of students' ability to understand concepts. The purpose of this study is to produce and determine the quality of Concept-Rich Instruction (CRI)-based e-module development products assisted by direct worksheets. The research method used is the research and development method (Research and Development) and the model used is the ADDIE (Analysis, Design, Development, Implementation and Evaluation) development model. Data analysis techniques were obtained from validation questionnaires (validated by a team of materials and design experts), practicality questionnaires (teachers and students), student response questionnaires and student concept comprehension tests used to see effectiveness. The results of this study were in the form of e-modules based on Concept-Rich Instruction (CRI) assisted by direct worksheets to improve students' understanding of concepts and it was found that e-module products were proven to be valid, practical and effective with a material validity level of 93% (very valid), design validity of 88% (very valid), practicality by teachers 89.3% (very practical), practicality by students 88.28% (very practical), and effectiveness (student response questionnaire) 85.72% (very effective). Based on the results and discussion, it was found that e-module products based on Concept-Rich Instruction (CRI) assisted by direct worksheets to improve students' concept understanding can improve students' concept comprehension skills.

Abstract

Although critical thinking is fundamental to 21st-century mathematics learning, research synthesizing how Realistic Mathematics Education (RME) develops this competency remains fragmented and underexplored. This study aims to map the literature profile, development trends, as well as challenges and recommendations of research related to the integration of RME and critical thinking abilities. A Systematic Literature Review (SLR) method was applied to 18 articles from Scopus and Google Scholar for the period 2019-2025 using VOSViewer bibliometric analysis. The results show that RME consistently improves critical thinking abilities through three clusters: learning implementation, RME characteristics based on real contexts, and effectiveness evaluation. Research trends evolved from effectiveness verification (2019-2021), technology integration (2022-2023), toward differentiated learning and exploration of local cultural contexts (2024-2025). This evolutionary pattern raises a critical question: whether such trends reflect the theoretical maturity of RME as a robust and coherent pedagogical framework, or whether they indicate fragmentation of approaches that risks diluting the core principles of RME. Main challenges include variations in learning design quality and limited digital infrastructure. The study recommends continuous RME implementation, strengthening of teacher education curriculum, and development of specific critical thinking measurement instruments for RME based mathematics learning are needed.

Abstract

The numeracy skills of students in Indonesia are expected to be at a level that supports contextual problem-solving and higher-order thinking. However, international assessment results indicate that the numeracy skills of Indonesian students remain in the low category and have not yet met expected standards, as reflected in the 2022 PISA results, in which Indonesia achieved an average score of 366 points in mathematics well below the OECD average of 472 points. This study aims to analyze the numeracy ability of junior high school (SMP) students based on three cognitive domain indicators: Understanding (U), Applying (A), and Reasoning (R). A descriptive quantitative approach was employed with 32 students selected through purposive sampling. Data were collected through a written test consisting of 6 items with a maximum score of 72 points, supplemented by semi-structured interviews. Results indicate that the average numeracy score was 30.34%, classified as Low. No student reached the High or Very High category; 56.25% of students were in the Low category. Per-indicator analysis revealed a consistent decline from Understanding (38.80%), Applying (27.21%), to Reasoning (25.00%). Item 1a had the highest achievement rate (93.75%), while item 2c could not be answered by any student (0.00%). These findings indicate the urgent need for authentic context-based learning that fosters higher-order thinking skills at the junior high school level.
