As technology continues to advance, the process of educational informationization is progressing steadily. This has made research on smart classrooms increasingly mainstream. However, understanding evolving trends in this field remains a complex challenge. This study explored the current status and future directions of smart classroom research. We conducted a visualization analysis using CiteSpace software. First, we retrieved research literature related to smart classrooms from the Web of Science Core Collection from 1990 to 2023. We then performed descriptive analysis and visualization scientometrics analysis, including the construction of co-citation, collaboration, and co-occurrence networks. From the co-citation network, we identified prominent journals, authors, and core literature on smart classroom research. Collaboration network analysis highlighted the patterns among researchers, institutions, and international collaborations. The co-occurrence network revealed the main categories and directions of research. By integrating descriptive and visualization-based scientometric methods, we delineated the developmental stages of smart classroom research, discussed current hot topics, and suggested future research avenues.
