At the same time, with the rapid development and rise of modern network education in our country, great social changes have taken place in the teaching mode of teachers' cultural and moral education concepts, students' cultural and educational concepts, learning styles, life management styles. Therefore, under the background of the development of basic education network information technology in the current new information age, how to effectively use the advantages of network information technology to guide the organization and coordination of the development of the school basic education network is also very important. This paper makes a simple analysis of the problems existing in the online sports live broadcast class and puts forward some suggestions.展开更多
