1. Most students' scores cannot be improved, and only a few students' scores can be improved.
2. Online classes should not be less effective for students with strong self-discipline and self-learning ability. In school, the teacher teaches according to the timetable, and the homework or exams are completed by himself. The online teacher still teaches online according to the timetable, and the students listen offline. Those who do not understand can also be played back, which is also homework or exam after class. The content of the program is the same, but not the same. It is supervised by teachers at school, and it is completely self-discipline at home.
3. Although many places now say that they do not stop learning and online teaching is in full swing, I personally feel that the quality of learning is not as good as physical teaching. Some students still know how to study. They will listen carefully and remember to take notes. However, there are still many things they don't understand, and it is inconvenient to ask questions. The learning atmosphere is not as good as in school. At home children simply do not feel the pressure of the upcoming college entrance examination. Without the power of pressure, learning quality cannot be improved without power.
