What do you mean by the number of weeks on the schedule?

From the beginning of school to the first week? Generally, a semester lasts 20-22 weeks.

At the end of last semester, the teaching department of the school worked out the courses of all grades and classes according to the changes of teachers' job transfer (promotion, job transfer or job transfer) and course change (from teaching physics to teaching) in the next semester.

Send me the weekly schedule of teachers in all subjects in time. After receiving the schedule, inform me to collect the teaching materials for this subject next semester, prepare the teaching materials, design the teaching plan and schedule, and start preparing lessons in time.

Extended information courses are usually arranged by the academic affairs office of the school according to the class hours stipulated by the Ministry of Education and local education departments, starting from the time sequence of the first class, and according to the main subjects (except Chinese, physics and chemistry, politics, history and geography) and other subjects (music, physical education and aesthetics). When teachers from different disciplines conflict, we should consider the time complementarity of teachers from different disciplines and try our best to arrange the main subjects every day.

That is, when Chinese, mathematics, foreign languages, physics and chemistry can't be arranged in class one or two, biology, politics (thinking), history and geography will be mentioned in class one or two. Other subjects such as music, physical education, art and information are basically arranged in three or four classes or five or six or seven classes in the afternoon.

In order not to affect students' cognitive and memory rules, we should also pay attention to the fact that the class hours of the same subject cannot be arranged continuously. Some local schools don't pay attention to this point, and arrange the class hours of some subjects in one row, that is, the content of one subject lasts for two classes, which seriously violates the objective laws and relevant regulations of students' physical and mental health development.
