A bibliometric analysis on the trends and educational strategies of universal single design in secondary education

Abstract

This study analyzed scientific production on Universal Design for Learning (UDL) in secondary education between 2022 and 2026 through a quantitative and retrospective bibliometric review. For this purpose, 55 articles were selected from Scopus, Web of Science, SciELO, and ScienceDirect following the PRISMA 2020 protocol. The analysis was conducted using Bibliometrix and VOSviewer and revealed thematic expansion toward artificial intelligence and the consolidation of international collaboration networks, adaptive learning, and digital accessibility. It was determined that UDL has become a strategic line of research for fostering inclusive and flexible learning environments in secondary education.
