With the advancement of information technology, academics have steadily strengthened their research and creation of a complete assessment system for college sports flipped classrooms, so as to improve school education quality. Teachers can use classroom evaluations to quickly identify the flaws in their own teaching approaches and switch to a more effective teaching mode. The old paper assessment approach, on the other hand, is inefficient, which wastes time and money. This paper will look at how to use an AHP-fuzzy matrix to create a thorough assessment system for college athletics flipped classrooms. The main algorithm of the AHP-fuzzy matrix is proposed in this work, as well as the fuzzy comprehensive evaluation approach. The stability and operating efficiency of the system are constantly rising. Stability rose from 77% in the first experiment to 85% in the 10th experiment, an 8% increase. The operating efficiency has risen from 85% at the beginning to 87%. Although the rise is not large, it has been stable. This also shows that the system designed in this paper not only has strong stability but also has high operating efficiency.
