Personalized Optimization Strategies for Physical Education Dance Training and Teaching in Modern Colleges and Universities Based on Multivariate Data Analysis

With the rapid development of economy and science and technology, it leads to the traditional sports dance training and teaching mode is hardly suitable for students' learning needs. Based on the teaching dilemma escribed above, a personalized optimization strategy for sports dance training and teaching in modern colleges and universities under the perspective of multivariate data analysis is proposed. In order to confirm the practical application value of the optimization strategy, the assessment scheme of the personalized optimization strategy of sports dance training and teaching in colleges and universities is designed under the joint effect of hierarchical analysis, entropy weight method and fuzzy comprehensive evaluation method, and the scheme is analyzed by examples. The evaluation value of the strategy is calculated as (0.7666, 0.1694, 0.1243, 0.0743, 0.0815), and due to obeying the principle of maximum affiliation, it is further concluded that the evaluation result of the strategy is excellent, which sufficiently proves the application efficacy of the strategy.
