Although the teacher's behavior has been praised by many people, I don't think the teacher should bear these expenses. The teacher's purpose is to let students acquire more knowledge, so these expenses should be borne by the school. Generally speaking, universities have more funds.
First, students' courses should pay more attention to practice. One of the biggest problems in China's university campus is that it pays too much attention to the study of theoretical knowledge. University should be a very practical learning stage. The purpose of this teacher is actually to improve students' practical ability. After all, the knowledge in the university still needs to be verified through practice.
Second, schools should give more resources to support. I think this school must give more support. Only school knowledge can make students get better learning conditions. The reason why there are good universities and poor universities in our country is that the resources of each school are different, and schools with more resources will naturally become good schools.
Third, the behavior of teachers at their own expense is unattainable. If I were this teacher, I would definitely not have such an operation, because 50 yuan is a big expense for a teacher. In fact, the salary of university teachers is not too high. Their salary is generally between 6000 yuan and 9000 yuan.
From a social point of view, the teacher's behavior can be affirmed by everyone, but from a personal point of view, I don't think it is suitable to make such a move. As a teacher, we must think from our own perspective. If the teacher keeps making such a move, then the teacher can't bear it.
