1. Life. The essence of emphasizing the life of situation creation is to solve the relationship between the life world and the scientific world. Therefore, to create a teaching situation, we must first contact with students' real life and discover and tap the resources of learning situations in students' vivid daily life environment. The problems should be some problems that students often encounter in their daily life. Only in the daily learning situation can students truly understand the value of knowledge. Second, we should tap and make use of students' experience. Any effective teaching begins with fully excavating and utilizing students' existing experience. Students' experience includes cognitive experience and life experience.

2. Be targeted. Pay attention to students' "zone of proximal development". It is inseparable from the teaching content, objectives and students. Have a clear purpose.

3. Visualization. The essence of emphasizing the visualization of situation creation is to solve the relationship between image thinking and abstract thinking, perceptual knowledge and rational knowledge. Therefore, the teaching situation we create should first be perceptual, visible and tangible, which can effectively enrich students' perceptual knowledge and promote the transformation and promotion from perceptual knowledge to rational knowledge; Secondly, it should be vivid and concrete, which can effectively stimulate and stimulate students' imagination and association, so that students can go beyond the narrow scope of personal experience and time and space restrictions, which can not only enable students to acquire more knowledge and master more things, but also promote the interactive development of students' thinking in images and abstract thinking.
