This bibliometric analysis explores the integration of semiotics within educational contexts, highlighting a transformative shift towards multifaceted understandings of knowledge construction through language, multimodality, and educational transformation. Drawing on 1823 publications from the Web of Science database, this study employs both co-citation and co-word analysis to reveal prevalent themes and keywords in the field of semiotics in education. The co-citation analysis highlights the evolution of semiotic theories and their application in educational practices, from foundational concepts introduced by pioneers such as Saussure and Peirce to modern interpretations that consider the impact of digital technologies on semiotic resources. Co-word analysis, on the other hand, uncovers key research topics such as multimodality, multiliteracies, and the role of technology in mediating semiotic learning processes. This investigation is novel in its comprehensive approach to mapping the semiotic landscape in education through bibliometric methods, offering insights into how semiotic theories shape educational practices and outcomes, especially in language teaching and learning. By synthesizing findings from diverse research clusters, this study emphasizes the importance of adopting a multidisciplinary approach to understand the dynamic interaction between semiotics, technology, and learning. It contributes to advancing educational research by highlighting the transformative potential of semiotics in crafting more engaging, inclusive, and effective learning environments in the digital era.
