1, strengthening the intuition of teaching, American mathematician Bruner said: "The best stimulus of learning is students' interest in materials. "Mathematics is a scientific, rigorous and abstract subject. It is precisely because of its abstraction that it is the main reason for the formation of underachievers. Therefore, when teaching, we should strengthen the intuition of teaching. Students with intuitive feelings will be more interested in learning this knowledge point. 2. Make use of teaching situation to make teaching lively and interesting.

Interest is the best teacher. In teaching, we should pay special attention to the learning mood of underachievers and use novel, vivid and interesting teaching scenarios to stimulate their learning interest. In teaching, I try my best to stop my voice and attract their attention with body language, so as to make the class rich and interesting and guide each student to enter a positive thinking state, thus achieving the teaching purpose.

3. Pay attention to emotional communication

Underachievers are often looked down upon by ordinary students, thinking that their intelligence development is low, and they are also very inferior and feel that they can't do anything well. When they achieve something, they need the encouragement and affirmation of their teachers. Therefore, teachers should create conditions for underachievers to enjoy the joy of success. As long as the underachievers accept the teacher, they will greatly mobilize their enthusiasm for learning, thus achieving the goal of autonomous learning. Therefore, in practical teaching, teachers should not only pay attention to their own image and be a teacher, but also pay attention to emotional education for underachievers. Fully affirm the advantages of underachievers, their slight progress, and urge them to study actively.
