: Using the theory of "interactive reflection training mode" for normal school students based on socio-cultural theory and constructivism theory, a "trinity" education and study mode with the participation of teacher and student subjects was constructed, which includes "case driven classroom teaching, peer collaboration education survey, and" double teacher "follow-up cooperative discussion. The double teacher system played a key role. To think and construct educational study within the curriculum system of normal university students, and to not only build educational study as a course after educational internship, but also fully consider the integration and integration of educational study with other practical courses such as educational internships and educational internships. In the process of educational training, special attention should be paid to binding educational training with curriculum ideological and political education, so that normal school students can experience professional ethics during the internship practice process, and enhance the experience of teacher ethics into an educational sentiment during the study process.
