Abstract: In the contex of digital education reform, soil mechanics—a core disciplinein engineering—is undergoing a transition from traditional one-way teaching models to digital teaching paradigms. This paper explores how digital instruction reconfigures the pedagogical framework of soil mechanics, focusing on its impact on teaching and learning dynamics. First, it demonstrates that the digital transformation soil mechanics education aimes to innovate the learning ecosystem, digital course resources, teaching methodologies, and educational evaluation models through information technology. Taking Ningxia University as a case study, this paper illustrates the collaborative optimization between the development of digital teaching materials and classroom implementation. It reveals that digital education transformation breaks down barriers of educational resources and traditional teaching space, thereby enabling personalized talent cultivation, flexible teaching approaches, and seamless integration of online-offline educational modalities.
