There are several reasons why PE teachers, as class teachers, can be concerned by the society:
First of all, in many people's minds, physical education class is not the main course, and it doesn't matter whether physical education class is good or not. Therefore, having a physical education teacher as the head teacher may not make much contribution to the students' physical education evaluation, especially to the contents of the entrance examination, which is why there are such problems.
In addition, this is also a concern for the whole teaching team of physical education teachers and the situation of physical education teaching. The emergence of these problems, in fact, is the ideological concept and the current teacher evaluation and even student evaluation system. From the perspective of the Ministry of Education, PE teachers, music teachers, art teachers and science and technology teachers can all be class teachers, because each teacher has a teacher qualification certificate, which meets the requirements of teachers. Just because they study different subjects doesn't mean they can't be class teachers. The reason why this question is raised also shows that people are more willing to let teachers with foreign languages be class teachers, because teachers with foreign languages can often occupy the class hours of physical education examinations.
Finally, the spokesman concluded that the first thing in "Opinions on Comprehensively Strengthening and Improving School Physical Education in the New Period" is to change the customs, so that it is no longer a problem to let a physical education teacher be the head teacher, but I hope he can become a fashion in the future. Let the documents of physical education and aesthetic education reform that we need to pay attention to in contemporary times be truly implemented.
Personally, I think physical education teachers can be excellent teachers, because teachers in any subject can be class teachers, and there is no unified framework for class teachers. Sometimes breaking the framework is a surprise.
