School-based training is a learning activity based on schools, taking practical problems as the research object and aiming at improving teachers' quality. School-based training is a training activity based on the development of the school and carried out in the practice of school work. School-based training mainly includes class discussion, special training, tutor guidance, project research and other forms of activities. School-based training can effectively solve the contradiction between work and study in teacher training, and relieve the pressure of time, funds and personnel brought by teachers' going out for training. Give full play to the dominant position and role of schools and teachers, and pay attention to solving teachers' practical problems, improving teachers' practical ability and teachers' professional development. This model has changed the "aphasia" state of primary and secondary school teachers in training, can stimulate the enthusiasm of schools and teachers to participate, and make teacher training activities more dynamic and efficient.

Second, focus on training

Centralized training refers to the activities that training institutions organize teachers to participate in theoretical study and skills training at the specified time and place according to the requirements of the education administrative department. The training goal is to improve teachers' theoretical literacy and improve the subject knowledge structure. The training content is subject-centered, knowledge-based, and educational theory and subject knowledge are the main modules. Common training forms include pre-job training for new teachers, training for rural primary school teachers, and training for backbone teachers.

Centralized training has three main characteristics: first, unified organization and arrangement, easy to manage; Second, the unified training course, the content is relatively systematic and complete; Third, a unified training form, using special lectures. This centralized way of unifying time, place, content and people is widely used in the early stage of teacher training, which can greatly improve the theoretical level of teachers and is a main form of teacher training.

Centralized training can send strong psychological hints to trainees, reflect the authority of training, and achieve good results in improving teachers' theoretical literacy, broadening knowledge structure and grasping the urgent needs of basic education reform. However, this model takes trainers as the center, the curriculum is set from top to bottom, the course content emphasizes theory over practice, the training requirements are the same, and the trainers, as listeners and bystanders, lack the enthusiasm for training.

Third, online training.

With the rapid development of information technology, network technology has become not only a tool for teacher training, but also a resource and environment for training. Modern distance education has the following characteristics. (1) openness. This is the most basic feature of distance education, which breaks through the closed state of conventional school education and can realize the sharing of educational information resources. (2) scalability. This is the functional feature of distance education. With the help of the internet, educational information can be transmitted to learners in all directions, and learning activities can be extended to different areas and different groups outside the school, which is in line with the concept of lifelong learning in modern education. (3) flexibility. Not limited by time, place and method, teachers can study freely according to their own actual situation, which has built a brand-new platform and way for teachers' training and learning.
