1. Teacher's principle: Answer any questions.
You can't tell students that you don't know, don't know, don't know. You must answer the question. Teachers should first find a solution to the problem.
Teachers often ask students questions.
In the process of teaching, teachers should not just talk to themselves, but should often ask questions to students.
The teacher can give the students the telephone number.
Students will definitely have questions they don't understand, but some students are afraid to ask questions in front of the whole class. Therefore, the teacher's telephone number can not only help students get answers effectively during the break, but also get answers immediately when students have questions, so as to prevent students from forgetting their own questions.
Teachers can buy such books to reward students.
