First of all, we should collect typical teaching cases through reading, classroom observation, investigation and interview, and then interpret the cases from multiple angles and in all directions. Among them, teachers can not only make technical analysis of classroom teaching behavior, but also discuss the teaching strategies and teaching concepts embodied in the case, and also explain the teaching theory problems involved. For example, when a teacher asked his students to do comprehensive training on fractional application problems, he came up with such a question: the price of a set of tables and chairs is 48 yuan, and the price of chairs is 5/ 7 of that of desks. What's the price of the chair? Under the guidance of the teacher, the students calculated the price of the chair as 20 yuan by various methods. Just as the teacher was preparing to sum up, some students suggested that the price of chairs might be 10 yuan. At this time, the teacher impatiently interrupted the students' thinking with "Don't guess". After class, the students said that if a table is equipped with two chairs, then the price of the chairs is 10 yuan. Through the analysis of this typical case and the examination of our own teaching behavior, we realize that although we shout "pay attention to students' development" every day, we often go our own way in classroom teaching, and rarely consider students' needs, and adjust teaching in time according to the information feedback from students.

Teachers should watch more classes of other teachers and talk to them more. In the process of observation, teachers should analyze how other teachers organize classroom teaching and why they organize classroom teaching in this way; Think about the differences and similarities between their own classroom teaching links and teaching effects and them; What are the inspirations of their teaching? What will I do if I have an accident? Through such reflective analysis, I can get inspiration from other people's teaching.

After a class or a day's teaching task, we should calm down and think carefully: whether the teaching methods are fully used and whether the key and difficult points are prominent; Which actions are correct, which are not done well enough, and which need to be adjusted and improved; Whether students' enthusiasm is mobilized, whether they study happily, whether they are satisfied with teaching, and what is the confusion. Think about these clearly, make a summary, and then record them to provide reference experience for future teaching. After long-term accumulation, we will certainly gain a valuable teaching wealth.
