We make the knowledge management concept of knowledge acquisition, knowledge application and knowledge creation as the core throughuot the whole process of homework management activities to realize the optimization of homework management process. It mainly illustrates the sharing design and application of homework digitization resources. The sharing and application of homework digitization resources will promote the accumulation of teaching knowledge, which has a guiding research significance for promoting the use of educational resources, the application of education knowledge and the virtuous cycle of transformation and accumulation.展开更多
