In order to deeply analyze and evaluate the changes in the comprehensive quality of college students' sports dance, the overall idea of systematically evaluating the changes in the comprehensive quality of college students' sports dance was established. Firstly, this article uses the triangular fuzzy number method to measure the evaluation information of the evaluator's dance curriculum plan according to the evaluation indicators. Then, evaluation information from different groups and analytic hierarchy process (AHP) are used to determine the weight of each evaluation index. Finally, this article constructs a website system based on Python's Django framework. In the final system test and questionnaire survey, it was found that users were relatively satisfied with the accuracy of their evaluations and believed that the accurate performance of in-depth learning data analysis would help them save more time and effort in course selection.
