This study explored how teachers undertook listening instruction with learners of English as a foreign language (EFL) through investigating teachers’ authentic classroom practices. Eight experienced EFL teachers working in Iranian private language schools participated in the study. Each teacher was observed six to nine times and each complete teaching session of each of the participants was audio-recorded. Findings revealed that teachers had knowledge of an extensive repertoire of listening techniques, and their teaching was composed of strategies at pre-, during-, and post-listening stages. Teachers also mostly drew on metacognitive and comprehension-based practices. While teachers employed a number of metacognitive classroom practices, there was a lack of teaching and explicitly discussing these strategies. Findings provide some pedagogical implications for novice teachers with regard to expanding their repertoires of practice and employing various classroom activities. The findings might also help inform teacher educators and curriculum developers regarding classroom realities and the extent to which research findings can inform teaching methods and classroom practices.

Increasing globalisation has spurred a flow of migrants worldwide. These movements include exchanges of migrants’ linguistic repertoires across regions, transforming the ways in which they define themselves in a multilingual society. Unlike identity categories such as ethnic identity, the contested concept of citizenship identity has remained underexplored in heritage language (HL) research. Focusing on Korean migrant families in Australia, this study extends the limited knowledge about the roles of citizenship in HL maintenance across different generations. Specifically, drawing on interviews with six Korean-speaking parents and their children, this study compares the ways in which migrant parents and their primary and secondary school-aged children relate a HL to their citizenship status. Thematic analysis reveals that while HL-speaking children tend to associate their language with national or ethnic identities, migrant parents are more likely to identify their children as global citizens whose HL competencies are essential for their future career and economic advantage. The study contributes to scholarship at the intersection of HL, citizenship, and globalisation.

There are few published estimates of vocabulary sizes amongst students in tertiary education. Research does not offer estimates of the vocabulary size tertiary students might be expected to possess, though estimates exist for K-12 education, some EFL contexts, and the general population. Such research is important. For reading comprehension during tertiary education, a vocabulary of minimally 10,000 words is recommended, along with proficiency in academic vocabulary. A recent study of three universities in the United Kingdom concluded pedagogical intervention was required, since estimates indicated undergraduates knew fewer than 10,000 words. A subsequent study of a New Zealand university found students knew 16,000 words and pedagogical intervention was not required. The current study investigates 433 tertiary students at an Australian university to determine if students required vocabulary support. It contributes to a research record allowing for comparisons internationally, nationally, and over time. Methods employed included the Vocabulary Size Test/VST and Academic Vocabulary Test/AVT. Results indicate an average vocabulary size of 16,117 words, with academic vocabulary well-known.

This paper reports on a pilot implementation of the FL2 approach and resources, developed to support tertiary students’ wellbeing as well as their second language learning (L2). The FL2 approach and learning activities were piloted in two Spanish language courses at Australian universities. Evaluation data were collected through an online survey of participating students and compared to the results of previous pilots conducted with students of Italian. Responses to scale items and open-ended questions indicate that the majority of participants greatly enjoyed their experiences in the courses and were satisfied with the learning opportunities provided, which shows potential for the FL2 approach. Evaluations of seven Positive Psychology-informed learning activities also piloted in this study were more nuanced. Taken together, these results suggest that designing curriculum to support student wellbeing as well as disciplinary learning can yield positive results. However, careful consideration must be given to alignment between FL2 activities and curriculum, as well as to students’ individual differences in the reception of Positive Psychology-informed activities.

This study presents the case of a multilingual refugee (Maji) of Kirundi, Swahili, French, and English, from Burundi living in the U.S., and examines the language ideologies and identities embedded in his transnational narratives. We analyze our focal participant’s multi-layered transnational experiences using Darvin and Norton’s (2015) model of investment that foregrounds the intersection of ideology, capital, and identity. Specifically, we center on dominant ideologies in Maji’s discourse and how he negotiated his ethnic, social class, and gendered identities. Our findings revealed that Maji, who adhered to discourses that promoted the English superiority, the prestige of dialectal forms of Swahili, Spanish, and English, and English as a global commodity displayed his awareness of language hierarchies and dominance. Yet, Maji, who drew on French for meaning-making, displayed contradictory ideas by framing French as a useless language in the U.S. as compared to English. Our study sheds light on the complexity of multilinguals’ identity construction and discusses pedagogical implications on how to support language minority students’ multilingualism.

Research in intercultural communication studies has demonstrated that social networking (SN) can affect language minority learners’ cultural adaptation/identity process. Furthermore, internet usage preferences play an important role in the cultural adaptation of mobility groups. Drawing on these two lines of development, the current paper aims to further examine the role of SN in the home and host cultural adaptation/identity process of Chinese language-minority learners in Portugal. Through collecting and analyzing questionnaires focusing on three cultural identity dimensions, participants’ use of SN for academic purposes, and their cultural adaptation and language minority learning, we found that the affordances provided by SN contribute positively to enhancing both the host and the home cultural identity. Furthermore, the academic purpose of language use on SN indicated a positive relationship between the use of SN and cultural identity. The findings shed new light on factors that influence participants’ Portuguese language learning during study abroad.

This study was to assess the spoken vocabulary knowledge and its role in incidental vocabulary learning from captioned television. The participants were a total of 87 minority students learning English as a foreign language in Australia. The breadth of their vocabulary knowledge was measured with a vocabulary size test, while the depth of their vocabulary knowledge was through an assessment of collocational and semantic relationships. The results indicated that (1) captioned videos are helpful for incidental vocabulary learning; (2) scores on the breadth and depth of vocabulary knowledge and incidental vocabulary learning from viewing captioned television are highly and positively correlated; and (3) scores on the depth of vocabulary knowledge can make a unique contribution to the prediction of incidental vocabulary learning at the form and meaning recognition level, in addition to the prediction afforded by scores on the breadth of vocabulary knowledge. The findings highlight a need to improve the depth of vocabulary knowledge for incidental vocabulary learning from captioned viewing.

This article reports initial parts of a classroom-based action research aimed to teach students to write a literature review (LR), which is considered as a critical, yet often overlooked genre, thus posing difficulties to the students. The existing works on LRs appear to treat the ability to write overviews of individual studies, and to combine them in acceptable ways, as assumed knowledge. In fact, for the learners in the context of the study, and in many second- and foreign-language learning contexts, such abilities are not shared among learners. Therefore, in the implementation of an initial short course, a genre analysis of 60 literature reviews from publications and completed theses in applied linguistics was conducted to identify suitable generic patterns used in literature reviews that could be implemented in the context. The result is a pedagogical genre of literature review, a genre description of LRs appropriate for the students’ English proficiency level, outlined in detail in this article with the teaching implication for this pedagogical context.

This study explores teacher perspectives on a government policy that seeks to integrate Indigenous knowledge into mainstream foreign language education in New Zealand schools. Based on in-depth interviews, the study found that language teachers generally support this educational change because trans/languaging involving English and te reo Māori (the Māori language) has become an ordinary practice in their teaching and school lives. However, foreign language teachers expressed a need for discipline-specific materials and professional development to help them integrate mātauranga Māori (Indigenous knowledge of Māori) into their teaching. Their concerns can be understood as a lack of support in interpreting “what,” “how,” and “to what extent” the policy will be implemented. The study suggests using a decolonising approach to help teachers affirm the relevance of Indigenous knowledge in their discipline. It recommends that policymakers adopt a pluriversal stance to ensure that diverse knowledge systems can coexist and interact harmoniously rather than compete with one another in the new National Certificate of Educational Achievement (NCEA) curriculum.
