Abstract

This study aims to determine the effect of the LOK-R learning model assisted by E-comic on the numeracy skills of class X SMA students. This study uses a quantitative approach with a type of research in the form of one group pretest-posttest design. The population of this study was all class X SMA ST. Yoseph Medan consisting of 149 students divided into 4 classes. The research sample was selected using a simple random sampling technique, namely class X-1 with a total of 37 students. The data used in this study are quantitative data. Based on the analysis of research data using the Paired Sample T-Test, the results obtained t_count = 102.66> t_(table) = 2.028, then there is an effect of the LOK-R learning model assisted by E-Comic on students' numeracy skills. The results of the data analysis indicate that there is a significant increase in students' numeracy skills after the application of the learning model. This proves that the use of the LOK-R learning model assisted by E-Comic has a positive effect on students' numeracy skills by 67%.

Abstract

This study aims to systematically review the literature on Realistic Mathematics Education (RME), Culturally Responsive Teaching (CRT), Artificial Intelligence (AI), and 21st-century skills (4C) to identify and bridge research gaps in mathematics education. The research employed a Systematic Literature Review (SLR) combined with bibliometric analysis using the PRISMA protocol and supported by VOSviewer and Biblioshiny software. From the Scopus database, 79 articles met the inclusion criteria and were analyzed based on publication trends, author collaboration networks, citation structures, and qualitative synthesis. The findings indicate a significant increase in research on RME and AI over the past decade, while the integration of CRT remains limited despite its philosophical alignment with RME. This study identifies five major research gaps—namely theoretical, empirical, methodological, population, and evidential. The integration of RME, CRT, and AI has strong potential to form an adaptive, contextual, and culturally responsive mathematics learning model that strengthens 21st-century competencies. These findings provide new directions for developing inclusive and technology-based mathematics education.

Abstract

The 4C skills—Critical Thinking, Creativity, Communication, and Collaboration—are essential for preparing students to navigate 21st-century challenges. However, results from PISA 2022 and Indonesia's Education Report 2024 reveal that foundational competencies remain low, particularly in rural contexts. This study aims to explore the manifestation of 4C skills among ninth-grade students at SMP Budhi Dharma Balige, North Sumatra, through performance on PISA-based mathematics questions. Employing a qualitative descriptive design, data were collected from 31 students using two PISA tasks and an unstructured teacher interview. Responses were assessed using a rubric-informed framework, and analysis followed the Miles and Huberman model. Results show that while students demonstrate strong communication and procedural reasoning (96.77% correct in Q1 Part 2), performance in critical thinking and argumentation remains limited (only 35% success in Q2 Part 3). The main barrier is the lack of integrated instructional strategies that promote higher-order and collaborative learning. The study concludes that while 4C skills are beginning to develop, their progression is fragmented and requires targeted pedagogical reforms. Recommendations include the use of project-based learning, culturally responsive instruction, and formative assessments to ensure equitable 4C development in under-resourced schools.
