Make teachers look more technological in appearance - multi-functional teaching all-in-one machine

Used a blackboard as a child. You can also increase the use of paid reading on mobile or courseware on mobile.

It's a pretty good thing, it's not the same as the kind of blackboard I used to buy, I used to have a lot of brushes, and now I have a shell in the whole piece. Personally, I think that the advantages of nano blackboard are as follows: nano blackboard electronic textbook, protect vision. That is, nano-intelligent components are embedded in their own textbooks, so that teachers look more technological in appearance. Serve teachers, serve teachers.

The system design experience is better. Inconvenient for me is to read more e-books, like to put the word straight over, and then the blackboard is too big to see. It is not convenient to write on the seat, and my table is occupied when there are many people. It is also a annoyance that people can't find the blackboard.

Talk about personal opinions. In the past, with the traditional blackboard, teacher preparation and syllabus needed to form words on it, which was very troublesome, and it was difficult for students to memorize and forget. Now it should be mechanized teaching, students do not have teachers to lecture, but everyone does homework brush brush.

It's simple, convenient, and efficient.
