Research and Thinking on Online Teaching and Learning in Secondary Schools in China Based on the Background of Epidemic Prevention and Control

Based on the questionnaire investigation and analysis of the online teaching of "suspension of classes without suspension of learning" in an urban middle school in Anhui Province, China, the paper holds that in the abnormal period of epidemic prevention and control, online teaching plays an important role in stabilizing social order and promoting students’ learning; however, after practical testing, online teaching itself has exposed many problems, such as a high proportion of teachers who are not skilled in operating equipment, the difficulty in implementing interactive teaching and in monitoring the students' learning situation, the low teachers' satisfaction with online courses, and so on. In order to "promote the deep integration of information technology and education and teaching", the researchers put forward some ways and strategies to alleviate the problems of online teaching from the meso-perspective, which are intended to enhance the operation ability of teachers and students to apply network media, enhance teachers’ ability to implement classroom teaching reform, strengthen the supply capacity of equipment and technology to ensure the operation of teaching, etc.
