As a teacher, are you willing to copy all your courseware for many years to your colleagues?

I am a professor in the department of mathematics at the university, and I will retire this year. He is the first batch of young teachers in the unit who contacted computers, and also the first teacher who started to do ppt. He had a similar problem, and I happened to talk to him about it.

The conclusion is: no.

My dad moved from a school in the north to a university in the south, and the teaching method changed from a lesson plan/blackboard writing to a projector in every classroom. Because he was exposed to computers very early when he was young, he learned five strokes and basic office software very early, so he was also the first teacher in his university to start using projectors for electronic teaching in the classroom. Because my father teaches mathematics, the main course is advanced mathematics, so there are a lot of mathematical formulas in the teaching plan, which is very difficult to input, especially in 2000~20 10, which mainly uses MathType, a plug-in of word and PowerPoint. In order to display the formula normally in ppt, he made great efforts. During my junior high school and senior high school, I often saw him constantly searching for resources and pictures on the Internet for a little effect, just to modify an imperfect place in the courseware.

My father is a very upright man. He gave lectures and treated students wholeheartedly, and was praised by students countless times. But only in the courseware, he is completely unwilling to give it. Because some teachers really just want to be lazy, that is, they are pure "Bai Piao", thinking that they can save some class time by getting the courseware, no matter how much effort and sweat my father has put into this courseware. When individual students ask for courseware, they will still give a version similar to pdf format, but they will never just give the complete ppt format courseware.

Not only other teachers want to be lazy, but also some students send their own courseware online to enjoy * * *, and even send it to Baidu document for the whole network to download directly. The income generated in it belongs to Baidu and the uploader, but the responsibility for courseware errors lies with the producer. How can you just give something like this away?
