The former encompasses a wide range of teachereducation initiatives at the levels of diploma, bachelor’s degree, postgraduate diploma, and even master’s degree for teacher licensure purposes. These are widely documented in the literature.What is important is how teacher professional development contributes to bolstering the teachereducator force, which is relatively insufficiently documented due to the very fact that different educational systems have somewhat different expectations of such programs in relation to the ideologies and theories underpinning the teacher professional development program design and curriculum offering. Taking stock of a postgraduate diploma program in English language teaching(PGDELT) for teachers’ continuing professional development with a 31-year history housed at a premier teacher education institution in Singapore, which has successfully graduated over 1, 000 English language teachers for colleges and universities in China, I intend to highlight some of its key features, as a former student and then a lecturer on the program, in order to draw implications for sustainable growth of language teacher education programs, especially those whose main purposes are to prepare teachers of English as a second or foreign language(ESL/EFL) and provide continuing professional development opportunities for such inservice teachers.展开更多

Kindergarten teachers' growth is the unity of continuity and discontinuity. "Crisis", "encounter", "awaking" and "exhortation" all can break off the continuity of professional growth of kindergarten teachers, put kindergarten teachers' growth into the stage of discontinuity, promote the kindergarten teachers to make a positive self adjustment in shocks, and open up a new stage for kindergarten teachers' growth. In order to promote kindergarten teachers' active self adjustment in shock, and impel kindergarten teachers to step out oftheir"comfort zone", preschool teachers should try their best to overcome the tendency of"comfort zone" and strengthen the spirit of reflection. The kindergarten should create a rich and colorful cultural environment, and establish a cooperative research community for kindergarten teachers.展开更多
