Abstract

This study aims to synthesize research findings from published articles addressing students’ mathematical communication skills and self-regulated learning. A systematic literature review (SLR) was conducted following a structured, standardized procedure, including the formulation of review questions, database selection, keyword identification, the definition of inclusion and exclusion criteria, article screening, and data extraction. Relevant studies were identified from reputable academic databases and systematically reviewed to ensure methodological rigor and transparency. The results of the analysis indicate that mathematics learning implemented through specific instructional models or learning strategies contributes to improvements in students’ mathematical communication skills and self-regulated learning. Furthermore, several studies report a positive relationship between mathematical communication skills and self-regulated learning in mathematics education. However, other studies reveal no significant relationship between these two variables. Various factors, including differences in sample characteristics, learning contexts, and research designs, influence these inconsistencies. Therefore, further studies using more controlled and consistent methodologies are needed to obtain more specific findings and to identify the key factors influencing the relationship between mathematical communication skills and self-regulated learning, thereby improving the quality of future research.

Abstract

This study aims to analyze the effect of social media use on students' mathematical communication skills. It employs a quantitative approach with a quasi-experimental design (non-equivalent control group design). The sample consisted of 60 eighth-grade students, divided into an experimental group and a control group. The experimental group received social media-assisted mathematics learning, while the control group received traditional instruction. The research instruments included a questionnaire on social media use and a mathematical communication skills test. The questionnaire used a 1-to-5 Likert scale, while the mathematical communication skills test was assessed using a rating scale with scores categorized into three levels: high, medium, and low, defined by intervals of values. Data analysis was performed using simple linear regression and a comparison of means between the two groups. This analysis was conducted using SPSS software. The results showed a significant difference in average mathematical communication skills between the experimental and control groups . Inferential analysis revealed that social media use had a significant effect on students' mathematical communication skills.  Furthermore, regression analysis showed that social media use contributed 27.4% to the development of students' mathematical communication skills, with the remainder influenced by other factors external to the study. These results indicate that social media can be a promising pedagogical tool for improving mathematical communication skills through interaction, collaboration, and the interactive exchange of information. Therefore, integrating social media into mathematics learning could create a more communicative and participatory learning environment.
