Teachers' professional development in Ye Lan has gone through five stages: non-concern stage, virtual concern stage, survival concern stage, task concern stage and self-renewal concern stage.

1, "not concerned" stage

This stage is mainly before the formal teacher education. In the form of non-teachers' professional orientation, individuals have formed relatively stable educational beliefs and have some "intuitive" and "pre-scientific" knowledge closely related to teachers' professional ability. The good character cultivated by life experience at this stage is an important life foundation for teachers' growth.

2. "Virtual attention" stage

This stage is mainly a normal learning stage, including internship. Individuals began to think about the requirements of qualified teachers. At this time, the primary and secondary schools contacted by normal students actually have some virtuality. They gain some experience in the virtual teaching environment, learn and train educational theories and teachers' skills, and have the seeds of self-reflection professional development.

3, "survival care" stage

This is the stage for the new teacher. Under the impact of reality, individuals have a strong sense of anxiety about their career development, paying special attention to the "survival" skills in professional activities, and career development focuses on professional attitude and motivation. Teachers at this stage need to find the knowledge and skills to maintain the most basic teaching "survival". They strive to control classroom discipline, stimulate students' motivation, evaluate students' homework, and establish good relations with students and parents.

When dealing with problems, we lack experience and need to turn to experienced teachers to accumulate knowledge and experience in teaching practice.

4. "Task Focus" stage

This is a period of steady development and continuous improvement of teachers' professional structure. With the mastery of basic "survival" knowledge and skills in teaching, self-confidence is increasing day by day, and attention has been paid to teaching from self-survival, so as to better complete teaching tasks and obtain good external evaluation and career promotion. At this stage, the focus has shifted from "can I do it" to "how can I do it?"

5, "self-renewal concern" stage

At this stage, teachers are no longer bound by external evaluation or career promotion, but consciously plan themselves according to the general line of teacher development and their current development conditions in order to seek maximum self-development. Can pay attention to the all-round development of students and accumulate more scientific personal practical knowledge.

Teachers in this period can pay more attention to problems as a whole and comprehensively, and pay more attention to classroom activities and effectiveness. Recognizing that students are the masters of learning and paying attention to whether students are really learning, teachers should not only help students understand the teaching content, but also encourage students to discover and construct "meaning" by themselves.

Teaching is not only limited to helping students achieve academic development, but also allowing students to achieve various developments in the process of teacher-student interaction. This stage is a high-level stage of teachers' professional development. Only teachers who pursue professional development unremittingly can enter the peak stage of this development.
