Driven by the dual strategies of digital economy and education powerhouse, educational digitalization has evolved from a tool-based supplement to a structural force reshaping the university teaching ecosystem. Taking the concept of “empowerment by data and intelligence” as the entry point, this paper focuses on the coupling relationship between educational technology and teaching paradigm. Only by embedding technology into the discourse system, knowledge production, and institutional arrangements of the teaching community can the paradigm shift from “digital teaching” to “teaching digitalization” be truly realized. The transformation framework constructed in this paper can provide an operable theoretical fulcrum and practical path for universities to formulate educational digitalization strategies, optimize educational technology governance, and improve teaching innovation effectiveness.
