Abstract This paper first designs the study of college students’ ideological and political participation behaviors and determines the independent, dependent, mediating, and control variables of multiple linear regression based on ideological and political participation behaviors. Then, the original data were obtained using questionnaires, the Cronbach’s Alpha coefficient was selected to test the reliability of the questionnaires, and the logical structure of the multiple linear regression model was used to explore the participation degree of college students in ideological and political education and the evaluation of teaching effectiveness based on the multiple linear regression model. The results showed that the relationship between the three dimensions of intrinsic ideological and political efficacy and ideological and political participation behavior was significant and positive regarding the participation degree of ideological and political education. In terms of teaching effectiveness, the regression coefficient R is 0.507, which indicates that the independent variable influences the dependent variable, i.e., 50.7% of the variation of the dependent variable “college students’ evaluation of Civics class”, with a small standard deviation, which indicates that college students’ evaluation of Civics teaching effectiveness and Civics teachers are the same. This paper aims to improve students' awareness of ideological and political participation, as well as their ability to participate and promote the cultivation of qualified citizens in the new era.
