1. Teachers should write about their own teaching experiences or teaching stories that they think are important, that is, they should be selective and typical, and they should not list everything in detail, but should choose around the central issue. It is not that all events can be cases, and it is necessary to be good at capturing the "bright spots" in the teaching process.
2. Cases should be written based on previous experiences, and the authenticity of the information in the cases should be maintained as much as possible, so that readers can feel immersive. The main body of the case, the student, is to inquire about the fight and investigate their true feelings.
3. Teaching cases are different from other teaching works.
Compared with teaching, teaching cases are mainly based on narrative in terms of style and expression, and have both discussion and explanation. In terms of thinking, it is a process from concrete to abstract, through the description of vivid teaching "stories", through the description of specific students and teachers' psychological feelings, reflect on and summarize the pros and cons of teaching.
