This matter has caused a lot of discussion on the Internet. Agree with anonymous that this kind of teacher is not worthy of being a model. Unjustified abuse of students is not only a matter of teachers' morality, but also has a negative impact on the school and leaves a psychological shadow on the abused students.
People who disagree hold another opinion. They believe that secretly taking photos is an infringement of privacy and portrait rights. Photographers don't know the cause and effect, and it is easy to use the pressure of online public opinion to cause cyber violence.
First of all, I think it must be a wrong educational method for professors to publicly abuse students. No matter what students have done wrong, they can be educated to take them to the office, explain the truth to them, give them self-esteem and explain the pros and cons at the same time. If you do something wrong and fail to pass the teacher's education, there will be school rules and regulations to punish you.
Secondly, a developed network has advantages and disadvantages. In the past, the social environment could only be solved by reporting letters and monitoring, but now the network is developed and there are many social software. Many people will upload things in their lives to the internet and use public opinion to ferment their influence. The advantage of anonymous video recording is that it has evidence, but the disadvantage may indeed involve legal issues. Video recording without others' knowledge is suspected of violating civil rights. If you have any objection to the teacher's wrong education method, it may be a better solution to stand up and make it clear directly.
In addition, it is very important to raise the threshold for teachers. In the past, people were proud of the teaching profession, and the threshold for teachers was relatively high. At present, teachers' salaries are not high, and some bad behaviors of a few teachers, such as accepting parents' red envelopes and insulting students for performance, make the threshold for teachers lower and lower. Education is the foundation of a country, and teachers also have a great influence on students. Only by improving teachers' threshold, professional ethics and comprehensive quality can we teach and educate people better.
