Traditional teaching methods have faced unprecedented challenges as a result of educational reform, but it also presents limitless opportunities. The development of the flipped classroom teaching mode provides inspiration for the development of a PE teaching mode. This paper connects PE teaching with the “flipped classroom” teaching mode and designs an evaluation system for PE flipped classroom teaching based on the perspective of knowledge construction. The weight values of the contents of all levels of the evaluation dimensions of classroom teaching effectiveness are established in this paper, as well as the conceptual model and data table structure of the system database. In addition, using literature, questionnaires, and case studies, this paper investigates the effectiveness and application ideas of the “flipped classroom” teaching mode in PE classes. Experiments show that this method has an evaluation accuracy of 95.37 percent, which is about 13 percent higher than traditional methods. It is feasible and practicable in some ways. Additionally, flipping the classroom can increase student engagement, improve test scores, and increase teacher satisfaction. This study is expected to promote the use of the “flipped classroom” teaching mode in PE classes at colleges and universities, thereby speeding up the reform of PE education.

In the process of developing major sports events, how to guide providers and users to provide and utilize the archives information resources of major sports events and realize the interaction between them is an important problem to be solved urgently in the development of major sports events and the archive service of major sports events. By analyzing the present situation of archive service of major sports events, especially the analysis of the opposite dependent subjects of service providers and users, we can see that the continuous development of archive services for major sports events will inevitably lead to constant changes in user groups and user needs, guided by the theory of information retrieval, knowledge management, and media effect. According to the service model of archive service of major sports events, the archive service model of specific sports events is constructed. In this paper, four kinds of event recommendation models are applied to the collected marathon event data for experiments. Through experimental comparison, the effectiveness of content-based recommendation algorithm technology in the event network data set is verified, and an algorithm model suitable for marathon event recommendation is obtained. Experiments show that the comprehensive event recommendation model based on term frequency–inverse document frequency (TF-IDF) text weight and Race2vec entry sequence has the best recommendation performance on marathon event data set. According to the recommendation target of the event and the characteristics of the event data type, we can choose a single or comprehensive recommendation algorithm to build a model to realize the event recommendation.
