Abstract: This paper is based on the ETA Physics Cognitive Model, Taking “Newtons Rings” as an example, starting from the experimental physics cognition (E), moving on to the theoretical physics (T) cognitive level, and then further delves into the applied physics (A) cognition. The three-level structure from the surface to the core, reconstructs the teaching content, optimizes the teaching process, and constructs a classroom teaching model that combines virtual - theoretical and practical aspects. Also, in line with the requirements of integrating ideological and political education into the college physics curriculum, it trains students physical thinking, helps them understand the spirit of physics, and appropriately cultivates students entire process of physical cognition. Practice shows that the teaching model built based on the ETA Physics Cognitive Model has achieved remarkable results. In class, students active participation has increased significantly, their enthusiasm has been enhanced, and their problem-solving ability after class has improved obviously.

Key words: ETA physics cognitive model, newtons rings, newtons rings experiment
