The rapid advancement of digital artificial intelligence technologies is profoundly reshaping the educational landscape. Within this context, knowledge graphs emerge as pivotal tools in the digital transformation of education, fostering personalized and intelligent learning environments while enhancing overall educational quality and efficiency. By enabling educators to visualize course content, knowledge graphs catalyze teaching innovation and curriculum reform. In blended learning environments, they enable personalized learning recommendations and intelligent assistance, thereby improving student learning outcomes. Moreover, knowledge graphs are instrumental in the recommendation of teaching resources, data-driven analysis of learning behaviors, curriculum knowledge visualization, and learning situation analysis, all of which contribute to more intelligent and precise educational resources. As technology continues to evolve, knowledge graphs are poised to drive profound changes in teaching and learning paradigms. However, educators must carefully integrate this technology, ensuring that its development and application align with the core principles of teaching and learning. This careful consideration is essential for achieving a seamless blend of educational innovation and the construction of knowledge graphs.
