The suggestion of updating training institutions can be written as follows: In order to upgrade better, teachers should put their work in peacetime and pay attention to the process. This is recommended: 1. Teachers should constantly instill the importance of continuous learning and the connection point between courses. 2. Encourage students to talk in batches in homework or class, so as to close the distance with students. 3. The combination of interview, telephone and SMS communication is better. 4. Do a good job in the ideological education of "continuity" in advance, so that students must persist in learning. Learning is a step-by-step process, and grades are spiraling up. 5. Start issuing renewal notice 3-4 class hours in advance, and ask students to hand in the receipt. Before the final exam, make sure that 80% of the students in this class have finished, and the rest will continue to urge. Parents' meeting must be held after the exam to ensure that as many children as possible renew their fees.
