Abstract: Promoting digitalisation of education is an important initiative for strengthening the nation through education, and knowledge graphs, as the primary support for AI to enter the cognitive intelligence exploration stage, is one of the most effective vehicles to carry forward digitalisation of education. Based on an exploration into the value of innovative application scenarios of knowledge graphs in the process of digital teaching, and an analysis of the logic of construction of knowledge mapping in course Pedagogy of primary education majors from three dimensions–dimensional analysis of value, content and means–the article proposes: 1) conceptual innovation: technology integration centered on the essence of nurturing people; 2) path reconstruction: construction of a four-dimensional stereoscopic goal system; 3) value guidance: in-depth integration of ideological and political elements in the curriculum; 4) ability enhancement: practical paths for the iterative improvement of teachers’ digital literacy and teaching skills; and 5) evaluation system: a holographic evaluation mechanism of human-machine collaboration. Finally, the article summarizes the effectiveness of knowledge mapping in practical teaching of Pedagogy by pointing out the future challenges arising from effectively observing the reality of technology.
