Seeing that many answerers on the platform wrote about the experience of primary and secondary school teachers, let me talk about the experience of being a university teacher.
As a young teacher in science and engineering, there is a lot of pressure. It is difficult to get a long-term employment contract when you first join the company, and most of them are either promoted or left if you are promoted or left. Translated into a human word: one term of employment for three years, and within two terms of employment, you must be promoted to an associate professor or agreed position, otherwise you will not renew the contract.
The most basic condition for being promoted to associate professor is: a National Natural Science Foundation (hereinafter referred to as "National Nature"), one SCI every year, and two professional courses are taken every year.
Double non-universities have basically these requirements, but the platform is low, so it is naturally difficult to get the country; lack of experimental equipment, and it is also difficult to issue SCI.
211 universities need to compete due to the limited number of associate professors every year. Generally, it is safer for two countries to write a paper in SCI zone one year.
985 universities, at least two countries, have 3-4 SCI District 1 papers per year; in addition, there are also requirements for scientific research funds deposited, such as vertical (government allocation) of 3 million, or more horizontal (money given by enterprises).
So, no matter what level of college, the pressure is very high. Ordinary schools have slightly lower requirements, but the scientific research conditions are lower; good schools have good scientific research conditions and higher requirements. Is it easy to pass the "3+3" assessment? No! To give an example of a sensible operation: professors also have assessments. If they fail the assessment, they will be reduced to the treatment of associate professors, and their salary will be deducted, and the number of enrollment places will be reduced; if they fail the assessment, they will be reduced to the treatment of lecturers, and their salary will be deducted, and the number of enrollment places will be reduced.
Under such pressure, I have been living a life that is more tiring than 996 since I joined the company. Go out at 8 a.m. on weekdays and go home at 11 p.m.; go out late on weekends and go home early.
I have taught a course this semester, twice a week. I attend classes during the day and do experiments when there is no classes. Prepare lessons at night, prepare lessons at night, write scientific research funding applications, or write papers.
I don’t know when such a day will end, anyway, there will be no change before being named an associate professor.
