In this review study, research trends related to the analysis of mathematics textbooks on the concept of proportionality were identified. The PRISMA 2020 method was used to search for relevant studies, consulting databases (ERIC, EBSCO, SciELO, SpringerLink, and Taylor &amp; Francis, Dialnet); repositories (FUNES, Google Scholar, and ResearchGate); as well as thematic issues of the Ontosemiotic Approach. Through the analysis of the identified articles, four categories emerged: formative analysis and intervention, theoretical proposals, didactical suitability, and content and didactical analysis. The findings of this study may serve to recognize trends in research on proportionality in textbooks and, consequently, to identify potential lines of inquiry on the topic.</p> Karol Mayreni Martínez Meléndez Lizzet Morales-Garcia José Antonio Juárez-López Copyright (c) 2025 Karol Mayreni Martínez Meléndez, Lizzet Morales-Garcia, José Antonio Juárez-López https://creativecommons.org/licenses/by/4.0 2025-04-01 2025-04-01 17 1 3 16 10.46219/rechiem.v17i1.177 https://www.sochiem.cl/revista-rechiem/index.php/rechiem/article/view/184 <p>This essay aims to discuss the tensions that may be hindering the incorporation of cultural aspects into the learning of current school mathematics, from the perspective of the Socioepistemological Theory of Mathematics Education. The paper seeks to relate the influence of globalization on contemporary culture and on the structuring of twentieth-century school systems, which initially fostered a monopoly of knowledge by the teacher. However, as the twenty-first century progresses, the proliferation of information technologies has seemingly facilitated the mass dissemination of knowledge to individuals. In addition, the essay argues for the importance of considering the Redesign of School Mathematical Discourse within the school system, as a means of opening the door to integrating mathematical practices into school mathematics. Nonetheless, in light of the challenges of the twenty-first century, it becomes necessary to complement this Redesign with the effective incorporation of critical thinking development, so that future citizens are equipped with the necessary tools to discern between what is true and what is false.</p> Manuel Ampuero Copyright (c) 2025 Manuel Ampuero https://creativecommons.org/licenses/by/4.0 2025-04-01 2025-04-01 17 1 17 26 10.46219/rechiem.v17i1.184
