Abstract: As a core basic course for physics majors, solid state physics teaching plays an important bridging role in understanding the structure, microscopic properties of solid materials and their macroscopic applications. However, the current teaching of solid state physics is faced with strong theoretical abstraction, complicated course content, lack of systematicity, and disconnection from the frontier of the discipline. For this reason, the paper proposes an innovative study of constructing knowledge mapping and intelligent teaching. Through the construction of solid physics knowledge mapping, visualisation of the theoretical knowledge points and their logical relationships, to strengthen the basic articulation. And relying on the intelligent teaching platform, a diversified solid physics teaching resource base is constructed to fill the knowledge fault. Further combined with the BOPPPS teaching model, the knowledge map is integrated into the whole teaching process in order to enhance students'ability to combine theory with practice and interdisciplinary application, which provides a new direction for the teaching reform of physics-related courses.
