Tracking Pre-service Teachers’ Changing Conceptions of Good Science Teaching: The Role of Progressive Reflection with the Same Video

A CD-ROM consisting of videos of two lessons by different teachers demonstrating exemplary science teaching was used to elicit, develop and track the changing conceptions of good science teaching of student teachers enrolled for the one-year Postgraduate Diploma in Education (PGDE) at several stages during the programme. It was found that the videos acted as an effective probe to elicit student teachers’ conceptions and had significant impact on those conceptions at different stages of the programme through the provision of teacher models demonstrating exemplary teaching. The experience has extended novice teachers’ awareness of alternative teaching methods and approaches not experienced in their own schooling, broadened their awareness of different classroom situations, provided proof of existence of good practices and prompted them to reflect on their current conceptions of good science teaching. Most importantly, the strategy of asking student teachers to watch the same videos on three separate occasions at different times of the course was recognized by them as a crucial element in facilitating their reflection on their changing conceptions of good science teaching. PGDE is the standard form of pre-service teacher education in Hong Kong. It provides qualified teacher status within Hong Kong. Student teachers enrolled for the PGDE have completed a relevant undergraduate degree.

悲情卡夫卡--发达工业社会时代下的再审视

试图在法兰克福学派的学对发达工业社会的分析与批判中,找到重新阐释卡夫卡作品的可能。他笔下的麻木的人群正是马尔库塞所描述的“单向度的人”;某些主人公并非如过云评论所言是“弱的英雄”,事实上反映了作家的无奈;因此,他对“城堡”的描绘事实上是对人类工业明暗淡前景的预言。

Exploring inclusive pedagogical practices in Hong Kong primary EFL classrooms

Social diversity is now commonplace in many communities in today’s globalised world. This diversity can be seen in any classroom of learners, and international studies have shown the complex ways in which disabilities, race, ethnicity, gender and social class can determine a child’s opportunity to succeed or fail in the education system. In Hong Kong, like in many educational contexts around the world, teachers are grappling with increasing diversity amongst their students, including teaching students with special educational needs (SEN) and non-Chinese speaking students (NCS) living in Hong Kong. This paper examines how three primary TEFL (Teaching English as a Foreign Language) teachers are constructing identities as inclusive practitioners as they grapple with enacting the inclusive education policy recently introduced into Hong Kong schools. The data are drawn from a small-scale collaborative reflective inquiry for teacher professional development. Drawing upon a sociocultural and critical framing of identity theory, we trace the three teachers’ identity construction as EFL teachers and inclusive education practitioners. We view the role of discourse, self-positioning and social context as key processes in teacher identity formation. Implications for furthering the development of inclusive education in EFL classrooms are offered.
