The basic task of teacher education is to train qualified teachers for basic education, while the focus of post-service teacher education is to train high-quality teachers. Pre-service education for teachers is to train teachers for basic education. The purpose of teachers' post-service education is to make up for and improve the shortage of teachers' pre-service education, or to pay attention to teachers' professional growth, that is, to pay attention to the renewal of teachers' self-knowledge, to help teachers enhance their professional decision-making ability and to expand the sources of knowledge engaged in professional activities. Teachers' after-service development mode is continuing education, such as school-based training, centralized training (including on-the-job training) and distance training. Teachers' after-service education is an important way to realize teachers' lifelong learning.
1The Regulations on Teachers' Qualification promulgated by the State Council DecreeNo. 188 on February 2, 995 and the Measures for the Implementation of the Regulations on Teachers' Qualification promulgated by the Ministry of Education on September 23, 2000 stipulate that teachers must continuously and irregularly carry out on-the-job training and assessment system! The teacher qualification system is the professional access system of teachers' profession. The validity of teacher qualification is the core element of teacher qualification system. The teacher qualification certificate system is closely related to the teacher training system. The effectiveness of teacher qualification will directly affect the quality of teacher training. Not only does it stipulate that all teachers must be trained on the job regularly, but the teacher qualification certificate also plays an incentive role.
Teacher education is gradually advancing towards "integration", which is essentially to combine the contents of teacher education, change one-off and final training into continuous and lifelong education, deepen pre-service education with post-service education, pay attention to the practicality of teacher education in pre-service education, and solve the problems of teacher post-service education in a different way from pre-service training. The integration of teacher education gives us a lot of thoughts: pre-service teacher education is not the whole, but the starting point and foundation. Teacher education should not only have a good starting point and foundation, but also have a developing future.
