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

Based on the constructivist theory and the second language acquisi-tion theory, teachers who adopt the new teaching model should play multiple roles to maximize the teaching effect, being not only thecourse designer, organizer, but also the guide, helper and facilitator in the process of teaching students to construct knowledge and be en-gaged in classroom activities as well.展开更多

Foreign language teachers often use code-switching as a skill of pedagogy to teach students to learn foreign language and promote their own teaching practice. Evidence shows that the proper sue of code-switching will promote English teaching practice, however, it is arguable that how to use native language to improve English teaching. This paper will discuss code-switching in Chinese English teaching with the SLA theories and put forward some guidance to teacher talk code-switching.展开更多

Imaging studies such as contrast-enhanced computed tomography(CT), magnetic resonance imaging(MRI) and ^(18)F-2-fluoro-2-deoxy-D-glucose positron-emission tomography/computed tomography(^(18)F-FDG PET/CT) are widely used to determine the presence and extent of tumors and metastatic disease, both before and after treatment. Advances in PET/CT imaging have allowed it to emerge as a superior imaging modality compared to both CT and MRI, especially in detection of carcinoma of unknown primary, cervical lymph node metastasis, distant metastasis, residual/recurrent cancer and second primary tumors, often leading to alteration in management. PET/CT biomarker may further provide an overall assessment of tumor aggressiveness with prognostic implications. As new developments emerged leading to better understanding and use of PET/CT in head and neck oncology, the aim of this article is to review the roles of PET/CT in both pre- and post-treatment management of HNSCC and PET-derived parameters as prognostic indicators.展开更多

Interaction plays a key role in second language classroom. Teacher questioning, as one of the teacher initiating activities, could facilitate students＇ language acquisition by asking questions and initiating responses from students. In this essay, two samples of teacher questions were looked into to find out the types, purposes and effectiveness of teacher questions. It was found that the experienced teacher was better at employing teacher questions for interaction than the student teacher. Both of them should improve the questions they asked in classroom. More effective teacher questioning should be introduced according to specific language learning environment by referring to the cognitive level of the students and more opportunities and motivation should be provided for students＇ response.展开更多
