First of all, let me talk about my understanding of your question. What do you want to ask is: If the income difference of teachers increases, what impact will it have? Because at present, the salary of teachers in our country is divided into 13 levels, but the gap between each level is not very big. If the gap between teachers' salaries is further widened, I think it will have a great impact.
This will stimulate teachers' enthusiasm for evaluating professional titles and engaging in teaching and scientific research. We know that the salary level of teachers is mainly determined by the length of service and professional title. The length of service increases year by year, and there is no way to change it through hard work, but the professional title can be improved through our own efforts.
At present, there is little difference in wages at each level, and the process of evaluating professional titles is very troublesome, which leads to many middle-aged teachers in primary and secondary schools who are content with the status quo and only want to teach students well, and rarely engage in teaching and scientific research. In many schools, teaching and scientific research seems to have become the patent of young people. In fact, middle-aged teachers have rich experience in education and teaching. If we can combine practice with theory and turn our own experience into words and videos, it will benefit education and more people.
However, it must be noted that if the gap is too large, it may lead to malicious competition among teachers. After all, people die for money and birds die for food, and huge benefits may drive some teachers to behave irrationally. For example: no longer willing to share educational resources with colleagues, no longer willing to waste energy with young teachers, using improper means to win votes in the assessment and so on. Teachers who can't evaluate their professional titles will be resentful, and they will complain a few words, which will affect their normal work.
Generally speaking, it is necessary to widen the gap in teachers' income, but it is definitely not suitable for overstretching.
