1. Due to the lack of clear guidelines on "stopping classes without stopping teaching", some schools have some formalism or increased students' burden in order to meet the requirements of "actively carrying out online teaching activities such as online teaching and online learning". For example, teachers are required to prepare lessons for the new semester and give classes to students of all grades, and teachers, parents and students are required to clock in online every day. Some students complained that the teacher assigned homework three times to fill the extended winter vacation. These behaviors are not in line with the original intention of "ensuring teaching progress and teaching quality during epidemic prevention and control".

2. Of course, for students who are about to graduate, especially senior three students who are about to face the college entrance examination, under the pressure of graduation examination and even the college entrance examination, it is completely understandable to be anxious and worried about the uncertainty of the start time and teaching plan. Different measures should also be taken for students of different grades and situations. For example, the Guangdong Provincial Department of Education stipulates that for the graduation grades of ordinary high schools and junior high schools, local schools can carry out online teaching of new semester courses after the original planned official start date, on the premise of ensuring full participation and learning effect; In principle, new courses are not taught in other grades before the start of school, and teaching is carried out according to the "zero starting point" after the start of school. In Guangdong Experimental Middle School, the students of Grade One and Grade Two are arranged to study at home, and the teacher is required to shoot teaching videos for the graduating class of Grade Three, so that each student of Grade Three can have a detailed curriculum, watch videos at home on time to study, and the teacher will also answer questions and guide the students online.

3. "Stop teaching and learning" is not just a slogan. There should be a clear teaching and learning plan. For the sudden online education, it needs the cooperation between home and school, teachers and students to explore together, but at least it should be clear that there are different teaching methods and course contents for students with different grades and needs, and dynamic adjustment should be made through feedback in the exploration to ensure or even improve the teaching quality in the most suitable way.
