Abstract: In view of how to carry out the teaching reform of physics core course "Mechanics" in the AI era , this paper has discussed and practiced the application of "AI scaffolding" teaching method based on smart courses in mechanics. By reshaping the teaching content, constructing teaching resources for smart courses and utilizing AI-assisted technology to create an "uninterrupted classroom". The innovative and critical thinking skills have been trained repeatedly in multiple sessions. Their ability to ask good questions and solve problems has been developed. Practical experience shows that this teaching method can effectively enhance inquiry enthusiasm, innovative thinking, and innovation capabilities. It provides new ideas and methods for the reform of mechanics course instruction.
