Generally speaking, copyright will be involved in teachers' work, such as original teaching plans, courseware, published test papers, etc., and some books and papers on education and teaching may also be written. If they are infringed, they are generally published and downloaded by publishing houses and websites without permission.

For example, Huanggang Middle School in Hubei Province has produced a set of simulation questions for the senior high school entrance examination, which is copyrighted. If others publish and distribute them without permission, their copyright will be infringed. However, if a teacher makes copies for students, he doesn't charge any fees other than printing, that is, only for teaching, not for profit, so it doesn't infringe copyright, and if he makes a profit, it does.

Copyright means that once a work is created, it has copyright, but if you claim rights, you need to have evidence to prove that you created it yourself. Copyright can be registered, and if periodicals, newspapers, publications, etc. are published under their signatures, they can also prove that they are original.

It is not easy for teachers to completely protect copyright, because your courseware and lesson plans are easy to flow out, and the content of the lecture is in accordance with the outline, which is less different from other teachers.

Another problem that makes it difficult for teachers to protect their copyright is that teachers are individuals, so it is difficult for you to leave your job and do something to protect their rights.

At present, there are more videos and audios of lectures, such as the training classes in New Oriental. Many videos and audios circulated on the Internet are recorded by students and posted on the Internet, which infringes the copyright, but it is difficult to pursue them.
