Today, educational prediction analysis has become an important tool for educational institutions to analyze students, and the performance of students in educational prediction analysis is a critical feedback. However, there are serious challenges in dealing with multi-factor datasets to improve the convergence and accuracy of predicting student performance. Therefore, this article comprehensively analyzes machine learning technologies, analyzes the community activities of middle-term students, and explores the impact of community activities on middle-aged students' practical skills. This paper uses Random Forest and Pearson Correlation Coefficient to analyze the relevance of the impact of community activities on student hands-on performance and use Teaching and Learning Algorithms (TLBO) to optimize Back propagation (BP) neural networks applied to predict students' future trends. The results show that the TLBO-BP model can more accurately predict dynamic changes in student performance and predict high accuracy in simple patterns.
