Do you like all-in-one lectures? After a backbone teacher suddenly ran out of power, there was no all-in-one support, and the class lost its former excitement. It reminds me of the textbooks of the Chinese teachers around me, the dense notes, although they are not the backbone teachers, they can teach well without the support of the all-in-one computer. Excellent teachers should prepare knowledge points in books and hearts, and they need to communicate with the same grade to get a thorough explanation for what they don't understand.
