The purpose of this study is to create the system of physical education grades processed by computer. The system was primarily made to offer physical education teachers more convenient, practical and flexible software while dealing with students' scores. In accordance with the spirit of Human-Computer Interaction and Human-Computer Interface, it will promote usability and flexibility and enable physical education teachers to accomplish keying-in, transforming, primary statistics and printing-out in Chinese by using mouse and key board. In the meantime, it fulfills the needs of preserving and checking the grades. This system is based on Microsoft Excel 97 and can effectively reduce the degree of difficulty in dealing with physical educational grades. We also hope it can enrich the discussion of improving teaching evaluation, and reach the end as promoting physical education teaching quality.
