As a core carrier for implementing the fundamental task of fostering virtue through education, the development of evaluation tools for the educational effectiveness of campus football is of strategic significance for deepening the reform of school physical education. This study adopts a mixed research method: Firstly, a theoretical model is constructed through open-ended questionnaires and semi-structured interviews, and then a scale for the educational effectiveness of campus football in colleges and universities is developed. The research shows that: (1) Exploratory factor analysis extracts a three-dimensional structure of cognition, emotion, and behavior, with factor loadings of 12 items ranging from 0.655 to 0.884; (2) Confirmatory factor analysis shows that the model has a good fit (χ²/df=1.823, CFI=0.974, TLI=0.968, RMSEA=0.044), and the reliability and validity tests meet the standards (CR=0.862~0.915, AVE=0.576~0.729). The study holds that the three-dimensional structure presents a progressive conduction path of “cognitive internalization-emotional identification-behavioral manifestation”, breaking through the limitations of one-dimensional evaluation of traditional tools. Among them, the cognitive dimension plays a fundamental role in value, the emotional dimension forms an intermediary link, and the behavioral dimension realizes the externalization of effectiveness.
