The development of learner autonomy depends largely on teacher autonomy. Teacher autonomy is also one of the most effective ways to support teachers in their classroom practice, as well as to improve and expand their professional preparation and practices. Apart from that, the research of teacher autonomy at different phases of teachers＇ professional development may provide insight into how to strengthen their autonomy capability and to better understand the differences in teachers＇ development at different stages. The current study aims to explore the different level of how university novice and proficient English teachers see themselves as autonomous practitioners on the five dimensions of teacher autonomy： teaching autonomy, assessment autonomy, school management autonomy, professional development autonomy, and curriculum development autonomy. In addition, it proposes coping strategies to facilitate the development of teacher autonomy, which may shed some light on cultivating teacher autonomy for teachers at different developing stages, development of expertise, and teacher education.展开更多

A class cannot be good or well performed without planning or preparation. Referring to the five stages model of Dreyfus(1986) and considering the teaching context of middle schools, the researcher uses qualitative and quantitative methods to get and analyze the data from 96 English teachers in three Chinese middle school. The findings show that in teaching content planning, novice and some proficient teachers cares more about the knowledge and the teaching itself, but the expert teachers pay more attention to the students' abilities and development as well as the knowledge; moreover, the novice teachers are more likely to focus on the teaching aims and choosing of teaching aid. This study also has significance in contributing to the teachers' expertise in planning.展开更多

Identification process of LEP （Limited English Proficient） students via nomination, testing and testing criteria to be identified as LEP, hence ESL if placed in the program is defined in detail Standardized testing process of these students based on the federal AYP （Adequate Yearly Progress） measures through regular state standardized tests depending on three types of instructional program that LEP student is placed in the school that are Bilingual Education Program, ESL Program, and Two-Way Immersion Dual Language Programs are described. Standardized testing process of these students based on the federal AYP measures through other means if exempted from regular state standardized tests such as LAT （Linguistically Accommodated Testing） and the conditions to be exempted are discussed in detail. Holistically rated English Language Proficiency Assessments that are implemented to fulfill federal AMAOs （Annual Measurable Achievement Objectives） measures are defined briefly. Physical features of LAT test as well as direct and indirect accommodations for LAT reading, mathematics and science tests are defined via the accommodation needed and the type of assistance provided.
