Evaluation of Reform and Practicality for PE Exam at BP Neural Network

摘要

Traditional sports theory exam divorced from reality, causing serious discrepancies of athletic ability and theoretical performance for student. From the respective of reform and practicality, using principal component analysis, the main component was extracted from five factors at the impact of PE exam. The results showed that improving students' ability to master the theory and developing creative thinking can be used as the main ingredient. Basing on BP neural network model, according to the actual situation, evaluation was conducted, and giving examples of evaluation.
