In content and language integrated learning (CLIL) classrooms, it is assumed that non-language content subjects provide more authentic communicative contexts for students to learn a foreign/second/additional language (L2). However, learning abstract concepts and academic language in an L2 simultaneously is also challenging for CLIL students. It is thus important for CLIL teachers to unpack and repack both abstract concepts and academic discourse for the students. ‘Semantic waves’, which model classroom practices of both unpacking and repacking, is arguably a key to understanding cumulative knowledge-building. Applying the concepts of semantic profiles and semantic waves, this paper analyses the classroom discourse of two CLIL science lessons in Hong Kong. In one lesson, the semantic profile mainly consists of downward shifts. The teacher adopted various useful strategies to unpack science concepts, especially with multimodalities, everyday L2 and students’ L1 resources. Yet, there was limited repacking. In contrast, some repacking was observed in another lesson, where the teacher provided explicit instruction on academic language and guided students through academic writing tasks. A semantic wave can thus be observed there. These findings on strategies for unpacking and repacking provide significant insights into knowledge building in CLIL contexts, and may hence illuminate CLIL pedagogical practices. © 2020 Informa UK Limited.

This study examines how teachers' discourse moves influence patterns of authority in the mathematics classroom. We identify changes in authority structure in one classroom taught by a primary mathematics teacher in Hong Kong. This teacher participant was one of 32 who participated in a larger teacher-intervention study that aimed to help teachers orchestrate dialogic classroom discourse for rich learning opportunities in mathematics. Previous research has investigated teachers' discourse behaviors and authority structures in mathematics classrooms, but the connection between the two has yet to be addressed in extant studies. Our analysis shows that certain features and patterns embedded in classroom discourse can constrain or enable certain kinds of authority in the classroom. This study contributes to understanding the ways in which dialogic discourse may influence how authority is structured, including how mathematics teaching and learning are enacted through authority styles, and how the discipline of mathematics is positioned from an authority perspective.

This paper documents the process and outcome of the development and validation of a coding scheme to analyse mathematics classroom discourse in the context of Hong Kong primary schools. The objective of this coding scheme was to systematically analyse teacher discourse behaviours before and after an intervention programme; the programme aimed to assist in-service teachers to develop conceptual and practical tools for engaging students in dialogical discourse in mathematics classrooms. This paper provides a detailed outline of what took place in designing and refining the coding scheme as well as improving its validity and reliability. The developed coding scheme can be effective for highlighting dialogic discourse, authority structures and student participation in mathematics classrooms and beyond. Consequently, it was possible to assess the efficacy of the teacher intervention programme. On the other hand, the developed coding scheme could be used to help teachers to gain a sense of efficacy over their instruction by giving them a roadmap for what they can do before and during instruction.

This article presents classroom discourse analysis as a tool for critical teacher education. It argues that such analysis can raise awareness of how teachers live out their ethical commitments in classroom-level interactions, but needs to be carefully situated. Drawing on the author's research conducted while teaching junior secondary students in Hong Kong, the article weaves classroom discourse analysis into a critical incident reflection focusing on ethical tensions that emerge from a class activity exploring dehumanisation. The activity used a pedagogy of discomfort in order to unsettle students' beliefs and practices, but in facilitating the activity, the teacher's ethic of care was also challenged.

Internationally, English is increasingly being adopted as the language of postsecondary education. In Asia however efforts by universities to promote the use of the English language both inside and outside the classroom may be threatened by the supposed reticence of Asian learners. This paper problematizes Chinese learners alleged reticence by examining how one group of undergraduates at an English medium of instruction university in Hong Kong were able to meet the demands placed upon them for participation in spoken activities within their English for academic purposes classroom. Interviews with students and teachers, classroom observations, audiovisual recordings of classroom interaction and documentary analysis were used to understand how students participated in classroom discussion. The results suggest that learners adopted particular oral roles and drew upon a range of resources in ways that enabled them to conceptualize participation in classroom discussion as, in part, the result of learner agency. Implications for classroom practices in content classrooms traditionally dominated by a transmission mode of teaching are discussed.

In September 1998, the Education Department of the fledgling Hong Kong Special Administrative Region implemented a controversial medium-of-instruction policy which compelled around three-quarters of the territory's hitherto English-medium secondary schools to switch to Chinese-medium teaching in Forms 1–3 (years 7–9). Only 112 schools were permitted to remain English-medium, but only on the condition that their content-area teachers make consistent use of English as the language of classroom instruction and interaction rather than, as had been the case in the last two decades of colonial rule, a mixture of Cantonese and English. This article presents the findings of a study which sought to determine the extent to which the post-colonial government's language policy has been translated into classroom practice in the reformed Chinese and English streams since 1998. The findings were derived from a questionnaire survey of a sample of undergraduates from the first two cohorts to complete their studies in the reformed Chinese and English streams, together with semi-structured interviews with students and teachers currently studying and teaching in the two streams. The findings indicate that teachers in both the Chinese and English streams have found it difficult to fully implement the new policy in their classrooms.
