Advances in International Applied Mathematics

With the advancement of the concept of core literacy education, mathematical modeling ability has become an important goal of junior high school mathematics education. Based on the Rasch model as a theoretical framework, this study constructed an evaluation index system of junior high school mathematical model concepts, compiled test tools, and conducted an empirical analysis on the second year junior high school students in Changzhou City. The results show that the overall level of students model concept is good, but the application ability is weak. The proportion of students with intermediate level is relatively high; The reliability and discrimination of the test volume met the measurement requirements. Based on this, some teaching suggestions are put forward, such as strengthening the teaching objectives of modeling, hierarchical teaching, and increasing practical application, so as to provide reference for the cultivation of mathematics core literacy.
