Research Status and Development Trends of Blended Learning in Mathematics Education: A Knowledge Mapping Analysis Using CiteSpace

Introduction: blended learning has emerged as a prominent area of research in the field of education, with particular interest in its application to mathematics education.Objective: this study aims to systematically explore the research status and development trends of blended learning in mathematics education.Methods: this study utilized 419 journal articles on blended learning in mathematics education, published in the Web of Science Core Collection from 2004 to 2024, as the research sample. Guided by the PRISMA framework, statistical and bibliometric analysis methods were employed. CiteSpace software was used to visualize knowledge maps, including authors, countries, and keyword timeline views, providing a comprehensive analysis.Results: the study showed that current research on blended learning in mathematics education is in a rapid development stage, with a loose network of collaborating authors, and that the United States has the largest number of published papers in the field of blended learning research in mathematics education, with a strong international impact. The research results were mainly published in Computers & Education, International Journal of Educational Technology in Higher Education and other journals. Blended learning in mathematics education research, from initial exploration to application extension to deeper integration with technology, showed a trend of development from conceptual framework building to strategy application to technology driven.Conclusions: this study provides valuable insights for educators and researchers to improve the effectiveness and validity of blended learning implementation in mathematics education.
