During the epidemic, our school used the tablet computer of Shiqiang Education Technology for classes. I feel that the tablet is really more convenient than the computer, because it is more convenient to do homework exams with a writing pen. Usually, if the teacher doesn't have time to take notes during the lecture, I can also take screenshots of the teacher's lecture records with a tablet computer, and I can also watch classroom videos after class. With this tablet, I feel that learning is not so difficult.
