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.

The study examined the relationships between self-regulated learning (SRL) strategies used by 2,894 bilingual primary school students and their Chinese and English reading test performance. Exploratory factor analysis of the self-reported SRL strategy use questionnaire yielded two factors of strategies (planning and monitoring) used in both Chinese and English reading. The analysis of the structural equation model indicated that the planning and monitoring strategies used in Chinese reading positively affected their corresponding strategies used in English reading. The Chinese planning and monitoring strategies directly and positively affected both Chinese and English reading test performance. The English planning had a positive effect on English reading test performance while the English monitoring strategy did not affect English reading test performance. The results contribute to the knowledge of SRL in second language and bilingual education in the Chinese context. Copyright © 2022 Routledge.

The discourse around combining local, national and international languages constitutes an important issue in the global education agenda (Kirkpatrick and Chau 2008). Ideas about how trilingual education ought to be designed and implemented vary across stakeholders. This study explores (1) the beliefs which early childhood education (ECE – ECE refers to teaching of young children up to the age of six) principals, teachers and parents exhibit about trilingual preschool education in Hong Kong; (2) the challenges in the trilingual preschool implementation processes, and (3) the mechanisms employed by ECE principals for coping with these challenges. Semi-structured interviews and observations were conducted to collect data from four preschools, and these were supplemented with documentary analysis. Findings indicate that the inconsistent beliefs among stakeholders about the aims of trilingual education and language choice, curriculum design, and instruction (pedagogy and activities) in trilingual preschools are the major challenge administrators-principals encountered impacting the implementation process. Teachers who lack professional knowledge and skills in the provision of trilingual education are also problematic. Moreover, the recruitment of native-speaking teachers of the target language is difficult due to perceived heavy workloads and poor pay. Findings also make evident important implications for policymakers, principals and professional development. Copyright © 2021 Taylor & Francis Ltd.

This study draws on the activity theory to explore how bilingual first-year secondary school students appropriate resources strategically in response to linguistic challenges in learning science through English in Hong Kong. The study explored 12 bilingual students' self-regulated strategy use by conducting in-depth interviews, stimulated recalls, observation and analysis of learning materials. Through analyzing these data, we examined how and why they appropriated and used resources strategically for self-regulated learning. The analysis revealed that the participants had used various artefacts (e.g. dictionary) and rules (e.g. evaluation criteria) to negotiate their respective roles (e.g. subject content learners and language learners) in situated communities of learning that consist of subject teachers, classmates, family members, private tutors and friends. Similarities and differences were found between the high achievers and the underachievers with regard to the use of resource-mediated strategies and the underlying reasons. The results inform the development of pedagogical schemes to enhance bilingual students' self-regulated strategic learning of academic subjects through English. Copyright ©Routledge.

In Content and Language Integrated Learning (CLIL) programmes, students are expected to master content knowledge and language simultaneously. The worldwide popularity of this kind of programme has called for professional development, particularly for content subject teachers who have to shoulder some responsibilities of language teaching in CLIL. There have been several frameworks or proposals for professional development of CLIL teachers. Yet, empirical studies investigating the effectiveness of CLIL professional development programmes remain scarce. This gap is particularly important, since the relationship between professional development and teacher change is complicated and there are various factors affecting whether and how teacher would change. This study implemented a 6-month professional development programme for a group of content subject teachers in CLIL in Hong Kong. With data gathered with questionnaires, interviews, lesson observations and post-lesson reflections, this paper reports the trajectory of three case teachers who seemed to experience different degrees of changes in beliefs and language awareness. These differences could be explained by the influence of such factors as school context, learning experience and subject discipline. This study yields important implications for teacher education in CLIL and teacher change.

The role of the first language (L1) in second language (L2) learning has been widely discussed and researched in the second Language Acquisition (SLA) literature. Benefits of L1 use have been found for vocabulary acquisition, and in facilitating comprehension thereby alleviating student anxiety. Many teachers appear to consider L1 use as a necessary option in L2 pedagogy. Disadvantages of L1 use are argued to be that it reduces exposure to the L2 thereby not enabling more implicit forms of L2 acquisition. Considerably less research has been carried out in English medium instruction (EMI) classrooms, surprisingly, as these are predicated on the benefits of massive exposure to the L2. This study investigated the effect of L1 and L2 use on teacher question types and interaction patterns in science lessons in early EMI and late EMI schools in Hong Kong. Our findings show that in late EMI, where there was much greater use of the L1, teachers tended to use higher order questions and were more interactive. In early EMI, despite students having received four more years of greater exposure to English instruction than late EMI students through the use of English as the vehicular language, teachers asked lower order questions and the interaction was more monologic. The implications for policy and pedagogy are discussed.

Content-based education programmes, in which a second/foreign language (L2) is used as the medium of instruction when teaching non-language content subjects, aim at both content and L2 learning. With such dual goal in mind, and with the rapid expansion of the programmes to contexts where students might have only basic L2 proficiency, there have been consistent calls for reconsidering the roles of first language (L1) in the teaching and learning process. The functions of L1 in content-based classrooms have been well documented, but it is necessary to have a more systematic approach to planning and using L1. This paper seeks to address this gap by applying the notions of 'curriculum genres' and 'task structure' when analysing patterns of teachers' use of L1 and L2 in a collection of content subject lessons observed in English-medium secondary schools in Hong Kong. With illustrative episodes presented in this paper, we would argue that 'curriculum genres' and 'task structure' can serve as useful tools for both researchers and teachers to analyse and critically reflect on patterns of pedagogic practices and language use in content-based classrooms. These will have significant implications for future research on using L1 and illuminate effective pedagogy in content-based education.

This qualitative study investigates the language ideology of a groups of Chinese language teachers working in Hong Kong’s secondary schools when they teach ethnic minority students. Drawing on interview data, this study reports on how these teachers’ language ideologies are in accordance/discordance with dominant discourse, and in what ways their ideologies impact their teaching approach and attitudes towards the students’ heritage language and culture. Key findings indicate that instead of promoting homogeneity as a prerequisite for success, the teachers hold a pluralistic language ideology and outline the potential for ethnic minority students to become linguistic and cultural brokers between the heritage communities and mainstream society. An inconsistence was found between the teachers’ positive language attitude towards heritage language and their self-distancing from the heritage language learning and use in school contexts. The findings implied that teacher education courses could enable teachers, as active agents, to re-negotiate the separate language ideology of the language policy at the macro level, deconstruct it in classroom settings and develop knowledge and beliefs to challenge and resist the ideologies that sustain the marginalisation of heritage language and culture.

In Content and Language Integrated Learning (CLIL) classrooms where students' L2 proficiency has not reached the threshold level, teachers have been observed to use L1 to assist students in grasping specific technical terms and abstract concepts. It is argued to be a 'realistic' approach to the learning problems caused by students' limited L2 proficiency, particularly in English-as-a-foreign-language contexts. Nonetheless, researchers have also warranted 'judicious' and 'principled' use of L1 so that both content and language learning are facilitated. The question thus remains is whether teachers can use L1 appropriately to suit their students' needs. This study seeks to address this question. It includes data from 30 Grade 10 lessons in Hong Kong CLIL classrooms, where students' L2 proficiency varied considerably. Using both quantitative and qualitative analyses, this study shows that when teaching students with limited L2 proficiency, teachers used a significant proportion of L1 in lessons to explain the subject content, interact with students and develop students' L2 metalinguistic awareness. In contrast, with students highly proficient in L2, teachers used little L1, mainly to provide translation equivalents for L2 subject-specific vocabulary items. This study thus shows that teachers seemed to be sensitive when making use of students' existing linguistic repertoires.

In this paper, I review the four articles in this special issue, elucidate the main challenges faced by bilingual teachers when helping their Cantonese-dominant students learn both the content and target language (English) through content and language integrated learning-compatible pedagogies, and give a critical appraisal of their respective contributions to good practices and theory-building in research on translanguaging or classroom code-switching.
