1. Give prominence to key points, draw inferences from others, and pay attention to practical operation. When explaining the knowledge points, Mr. Sun Weigang always sticks to the theme, analyzes the core of the problem, shows the students the idea of solving the problem step by step, and explains the knowledge points thoroughly through repeated explanations.
2. Explain it briefly. Starting with the essence of the problem, Mr. Sun Weigang made the students grasp the difficulties easily with easy-to-understand language. This method not only enables students to concentrate on their studies, but also enables students to quickly grasp knowledge points and improve learning efficiency.
3. Close to students' reality. Teacher Sun Weigang can always combine the theoretical knowledge in textbooks with students' real life experience, and let students know the specific application of knowledge points through life cases, that is, close to students' lives, so that students feel that knowledge is valuable and meaningful.
Expand knowledge:
Sun Weigang was born in a military family on 1954. 10 years old, admitted to the Air Administration Art Troupe and became a dancer. 1977 After resuming the college entrance examination, Sun Weigang was admitted to the Department of Mathematics in Peking University through her own efforts. While studying in Peking University, Sun Weigang discovered the problems in mathematics education and decided to study mathematics education. Therefore, he also postponed his master's degree.
Sun Weigang believes that mathematics is a discipline that studies concepts such as quantity, structure and change, and it is a basic tool for human beings to understand the world. Mathematics education is an important way to cultivate people's mathematics literacy and thinking mode. He advocated guiding students to master the basic concepts and methods of mathematics through systematic teaching and practical activities, and cultivating students' mathematical thinking ability and problem-solving ability.
In teaching methods, Sun Weigang put forward the concepts of "systematic learning" and "subject knowledge". He believes that mathematical knowledge is intrinsically linked, and knowledge points should be connected in series to form a knowledge network and establish a systematic cognitive system. At the same time, through targeted exercises, students can deeply understand and master knowledge points, and cultivate their mathematical thinking and problem-solving ability.
In practice, Sun Weigang has conducted many teaching practices in the experimental class of No.4 Middle School. Through systematic lesson plans and targeted exercises, he raised his students' math scores to a new level.
For example, in a mock exam before the 1985 college entrance examination, the average math score of Sun Weigang class was more than 30 points higher than that of the whole grade, and the college entrance examination score was also better than other classes. In addition, in his experimental class, many students won prizes in the national mathematics competition.
Sun Weigang is a firm practitioner and reformer. He always believes that his educational ideas and methods can really improve students' learning ability and comprehensive quality. He constantly explores and tries new teaching methods and means to better meet the needs of students and social development.
Sun Weigang's contribution is not only in the field of mathematics education. He is not only an excellent teacher and educator, but also a visionary thinker and practitioner. Through his own practice and thinking, he promoted the reform and development of education in China. His educational ideas and methods have not only been widely used in Beijing No.4 Middle School, but also aroused widespread concern and discussion in China.
To sum up, Sun Weigang is one of the important figures in China's mathematics education and education reform. His educational thoughts and methods not only injected new vitality and motivation into China's education, but also provided beneficial reference and enlightenment for the world's mathematics education and education reform.
