First, in the basic education stage, especially in the primary school stage, online learning is not as good as classroom learning. Implementing the "three-oriented" principle in classroom learning environment, teachers' inspiration and guidance, students' active participation, classroom adjustment, scenario creation, timely feedback and correction, moderate practice and consolidation of digestion, and using modern teaching methods such as multimedia can optimize classroom structure, arrange teaching time reasonably and maximize classroom efficiency. However, online learning is limited by time and space, and the above teaching principles, methods and means are not focused and difficult to implement.
Second, the current online learning schedule is 20-25 minutes per class, which is short, and the teaching methods can only be explained mainly by teachers. When teachers and students don't meet, students' self-control, understanding and digestion, active learning consciousness and personality differences and imbalances will have a great negative impact on learning results. Online learning must use computers, mobile phones and other radioactive electronic products, which may affect children's health for several hours a day, five days a week. In addition, some students may indulge in the internet through studying, playing games or other things unrelated to study, which has a negative impact on children's psychology. Asking for fish is counterproductive.
Third, in the case of an epidemic, only online learning can be carried out. In winter, the house thinks that it is necessary to reasonably arrange the content, scientifically plan the curriculum, carefully design the teaching by teachers and combine various teaching methods. Teachers, parents and students of the school should be unified online, form a joint force, ensure the time and efficiency of lectures, use online learning to maximize the completion of more classroom learning tasks, and minimize the learning losses of students before returning to school.
