Compulsory Education Mathematics Curriculum Standards (2022 edition) puts forward the core literacy of the model concept. There are now many studies that concentrate on the model concept, but there are seldom any thorough generalized studies on this topic. The following results are reached by adopting the method of literature analysis to synthesize the pertinent research literature on the model idea in China: (1) The current research on the model concept at the compulsory education level has a very broad scope and includes in-depth investigations on the model concept's status, significance, the classroom design, and penetration strategies of model concept. (2) Most studies are conducted in terms of curricular content and subjects, and they focus on a limited number of fixed themes, such as quadratic equations, quadratic inequalities, and functions. To demonstrate how to fully understand the model concept, researchers offer practical examples and instructional designs. (3) But in terms of curricular styles, there aren't many studies on the model concept. To strengthen the research content, encourage in-depth study by academics and front-line instructors, and increase the effectiveness of the model concept's penetration, it is required to extend the research direction and the entry point.
