1, stimulate learning interest and improve learning enthusiasm. We must start from students' life experience, Friedenthal-Mathematics comes from life and must also be rooted in life. In teaching, we train students to experience mathematics activities personally, stimulate their desire to explore actively, and make them gain as many successful experiences as possible. Proper use of educational technology can vividly display the teaching content, thus achieving the characteristics of both sound and shape, bringing good sensory stimulation to students, stimulating students' interest in learning mathematics, and thus gaining intuitive experience.

2. Harmony between teachers and students, enhancing the trust of underachievers. Which is that premise of "integration of teach and doing". Love is the most effective means of education. Teachers' love is like spring rain, which moistens students' hearts. When the underachievers experience the teacher's love for them, they will become "close to the teacher and trust the teacher's way."

3. Cooperative learning. It is not a group, but a prerequisite for an effective classroom. It is impossible for a teacher to consider every student's hobbies, learning methods and existing math level. Only through cooperative learning can we discover, communicate, reflect, feel and experience mathematical knowledge at multiple levels. Independent thinking, peer support and learning strategies and skills are all quietly formed in such learning activities.

4, with the help of collective strength, subtle influence infection. The collective strength is infinite. I found that a learning group with a certain learning purpose and unity can effectively restrain the behavior of underachievers, influence them subtly, and make the transformation of underachievers work wonders. For example, there are eight underachievers in my class. I teach science system, which puts most students in my class on the right track of learning mathematics. The atmosphere of learning and using mathematics in the class is strong, and the math scores are ideal, which is also a great educational force for eight underachievers. In such an environment, they often unconsciously feel the collective edification and pressure.

In a word, the educational transformation of underachievers is very complicated. Teachers must understand and master each student's hobbies and existing knowledge level, adopt various learning methods such as autonomy, cooperation and inquiry, have enough teacher love and patience, find the breakthrough point to stimulate learning motivation, encourage them to be positive, and turn underachievers into qualified talents with all-round development in morality, intelligence, physique, beauty and labor.
