Abstract

This research was motivated by the difficulties of junior high school students in linear equation system material. The focus of this research is to produce the Hypothetical Learning Trajectory (HLT) system of linear equations based on the development of Learning Trajectory (LT) with the aim of research to improve students' mathematical communication skills. Research method used design Research with 3 phases: Preliminary design, teaching experiment, and retrospective analysis. The subject of study in SMP grade VII in Tasikmalaya district. This research uses the instrument of communication skills test students. Processing of research data using test-T.  Based on the results of the research obtained: (a) HLT results from the development of LT linear alignment system in RME to improve student mathematical communication skills; and (b) students who acquire RME learning have increased mathematical communication skills greater than those who acquire conventional learning.

Abstract

Mathematical reasoning and mathematical communication are two fundamental dimensions of learning mathematics in higher education that are often investigated separately. This article aims to reconceptualize their relationship through an epistemic–discursive perspective, viewing reasoning and communication as mutually constitutive practices in undergraduate students’ mathematical activity. The study employs a systematic literature review of articles published in internationally reputable journals over the last decade that address mathematical reasoning, communication, argumentation, and discourse in higher education contexts. The synthesis was conducted using thematic synthesis enriched by theoretical analysis. The findings indicate that mathematical reasoning cannot be fully understood without considering the communicative dimension and the discursive norms that mediate it, while mathematical communication functions as a medium of thinking and meaning-making rather than merely a means of expression. Based on these findings, the article proposes an integrative conceptual framework that positions mathematical argumentation and epistemic norms as central mediators between students’ reasoning and communication. This study contributes theoretically by offering a reconceptualization of reasoning and communication that is relevant for research and teaching in undergraduate mathematics education.
