Mature teacher training is mainly aimed at the early stage of teachers' career, aiming at helping them build solid basic knowledge and educational skills. Training at this stage usually focuses on basic educational skills such as teaching methods, curriculum design and teaching evaluation. Through these trainings, teachers can be familiar with the teaching process, enhance their understanding of students' needs and improve the quality of education.
Teacher training in the promotion period pays more attention to teachers' professional development and deepening. In the middle and late teaching career, teachers have acquired certain basic knowledge and experience, which can further expand their professional fields and improve their education level. Teacher training at this stage can include more professional courses, such as educational leadership, curriculum development and innovation and educational research. In addition, teachers can continuously improve their professional quality by attending academic conferences, observing and reflecting on teaching, and interacting with other educational experts.
To sum up, the training of senior teachers in primary and secondary schools needs to be selected according to the actual situation and development needs of teachers. For new teachers, mature training may be a better choice to help them build a teaching foundation. For teachers with certain educational experience, it is more suitable to participate in upgrading training to further improve their educational level and professional quality. Finally, teachers need to make training plans according to their personal needs and career goals.
