Online education is a hot topic that is widely concerned in various countries today. In the era of mobile internet, countries around the world have made various effective attempts at online education, but online education is more of a supplement to school education, and large-scale normal online education lacks cases. The “School’s Out, But Class’s On” campaign launched by the Chinese government during the COVID-19 epidemic created a large-scale, normal online education application. An article published in Best Evidence of Chinese Education analyzed the background of this large-scale online education, clarified the foundation of large-scale online education, and revealed the impact of the largest online education activities on society and education. According to the authors：
- Large scale online education accelerates the integration of educational technology and teaching.
- Large scale online education promotes the reconstruction of ecological teaching model.
- Large scale online education promotes the integration of home education and school education.
In this sudden epidemic, the implementation of “School’s Out, But Class’s On” enabled 270 million students in China to learn online. However, in the implementation process, online teaching also reflected some problems. These questions put forward new requirements and new goals for online learning, as follows:
- How to better integrate technology and education;
- How to make students learn more autonomously in online teaching, teacher teaching to be more effective, and online teaching models to be more reasonable;
- How to make home education and school education more closely linked through online learning, these are the problems that need to be solved in online teaching.
