In teaching, he carefully prepares each class according to the actual situation of students. He not only made advanced mathematics courseware, but also used a lot of graphics and animations to make teaching more intuitive and vivid. He also paid attention to expanding students' knowledge, interspersed some mathematical allusions and interesting stories that mathematicians studied hard in class, and vivid classes improved students' enthusiasm for learning mathematics. According to the problems encountered in the teaching process, he constantly summarizes and improves his teaching methods, humbly accepts students' suggestions to strengthen the summary and review of mathematics knowledge, increases the time of classroom practice in teaching, and improves students' ability to solve problems. This teaching method of cultivating students' practical ability is very popular with students. He also combined some learning methods and innovative thinking to give correct education and guidance to some students with learning difficulties, so that they can get out of some misunderstandings in learning methods.
In order to strengthen the study of mathematics, he asked students to hand in their homework every week, carefully correct it, comment on the problems in the homework in class, often praise the students who encourage them to study hard, and constantly improve their confidence in learning mathematics.
