Rethinking resources: a more-than-human reconceptualization of Chinese-Canadian children's heritage language practices at home (2026)
A persistent decline in heritage language (HL) has been observed among immigrant children in North America, largely due to insufficient HL resources and support in mainstream societies. Existing studies on early HL maintenance at home often privilege family language policies and intentional practices, yet HL resources and materials within domestic contexts remain underexamined. Simultaneously, an emerging paradigmatic shift from human-centric to posthuman in early childhood education highlights the agential powers of more-than-human elements in generating unexpected (re)configurations of children. This necessitates re-envisioning children’s literacy be(com)ing and rethinking what counts as early literacy resources beyond intentionally pre-designed and human-centered rationalities that long dominate the field.Grounded in posthuman theories (e.g., Barad, 2007; Deleuze & Guattari, 1987), this study reconceptualized home-based resources and practices for early Chinese HL (CHL) development by unfolding the dynamic, ongoing interplay of children and the more-than-human agencies where new possibilities of knowing/becoming Chinese literacies emerge. Drawing on posthuman-informed ethnographic approaches, the study involved micro-mesh material-centered interviews and observations with children (aged 2-6 years old) from three Chinese immigrant families in BC, Canada, during both learning and playtimes. Data were derived from field notes, video recordings, photographs, and researcher journals from year-long home visits, capturing children’s embodied engagements with material/discursive/affective forces and the spatial configurations of their homes. Data analysis revealed dynamic CHL assemblages composed of child-material-space entanglements that continually evolved within the flow of daily life. CHL acquisition emerged not only through activities with intentionally and explicitly designed Chinese language resources but also diverse embodied, sensory, and affective experiences co-created by children and a wide spectrum of more-than-human elements. These embodied engagements, or material-discursive practices, enveloped young learners’ linguistic and non-linguistic communications, offering children opportunities to enhance their CHL development through processes such as word building, character recognition, and communication skills—all of which demonstrate children becoming literate through the human-nonhuman interconnectedness. Findings highlighted the emergent, unbounded, and rhizomatic nature of early HL development, challenging the pre-determined literacy growth trajectories. By attending to materials and child-material intra-actions, this investigation illuminated the often-overlooked, “hidden” resources and practices in home CHL education.

Beliefs and practices in teaching English as an international language: a multiple case study of secondary English teachers in South Korea (2024)
Despite an accumulated body of research arguing for the legitimacy of English as an international language (EIL) or varieties of English used in international and multilingual contexts, American standardized English has remained popular and is prioritized in comparison to other English varieties within Korean society. Little research has investigated how educational policies associated with teacher recruitment and teacher education have responded to these research findings regarding EIL and how secondary Korean teachers of English have taken up the EIL influence in their teaching in Korea. Against the backdrop of a critical analysis of the current English educational policies concerning EIL in Korea at the macro level, this multiple case study focused on factors (teachers’ schooling, teacher personal experiences, coursework in teacher education, and work contexts) influencing five Korean secondary English teachers’ beliefs and teaching practices in incorporating EIL at the micro level, utilizing multiple data sources such as semi-structured interviews, class observations, surveys, and documents collection. Drawing upon the theoretical frameworks of language ideology and teacher cognition, analyses of data suggested that the teachers’ level of acceptance of EIL varied according to their exposure to different English varieties and contact with English users from diverse contexts; however, all teachers assigned a higher status to standardized English in English-speaking countries over other English varieties in their teaching in Korea. Their decision to incorporate EIL into their teaching was also influenced by social disparity among students and their unequal access to educational resources at home and in schools. Further, findings revealed the focal teachers’ awareness of EIL did not automatically translate into teaching practice due to practical challenges such as lack of guidelines for teaching EIL, insufficient instructional resources, and high-stakes college entrance examinations, as well as the need to comply with the national curriculum. The findings have the potential to inform policy changes and English teachers’ education and professional development in Korea and beyond.

New hierarchies, new middle class: a critical ethnography of English as a medium of instruction policy in Nepal's public schools (2022)
Despite continued calls for the “multi/plural turn” (Kubota, 2016a; May, 2014) for instructional practices and “linguistic human rights” for education through mother tongue (Skutnabb-Kangas, 1988), there is currently a global surge of English as a medium of instruction (EMI) in school education that situates English in a dominant position. This study is motivated by such a widespread of EMI in Nepal. Guided by the theory of “Critical Language Policy Studies” (Tollefson, 1991, 2006), this study explores the development and enactment of EMI policy at Nepal’s public schools and what they mean for diverse students along the lines of language, ethnicity, gender, and social class. I used “critical ethnography” (Anderson, 1989) and “critical policy analysis” (Diem et al., 2014) as research methods to provide a holistic and thick understanding of the EMI policy in Nepal. The data were gathered through participant observations of EMI lessons, interviews with policymakers, school administrators, teachers, parents, focus group interviews with students, field notes, and written artifacts. The findings demonstrated how EMI has evolved as a de facto medium-of-instruction policy through the state’s hidden agendas of envisioning education as a service industry, eventually creating privatization in public education that favors EMI. Aligning with the macro-level discourses, meso-level policy agents (e.g., parents and students) have been socialized into “neoliberal imaginations” (Abbinnett, 2021) of EMI to enter the new middle-class identity, which has become a founding ideology to support the growth of EMI in Nepali public schools. At the micro-level, through the mechanism of EMI, the school has served as a reproducer of social class and language hierarchy. The results further showed how EMI practices without planning and prerequisites (e.g., qualified teachers) resulted in the poverty of content learning and, therefore, epistemic inequalities. The classroom discourse analysis further revealed how teachers carried an agentic role to scaffold the limited English proficiency of their students by using Nepali (a dominant national language) as a supplementary language, yet perpetuated unequal languaging in the absence of students’ mother tongue. Together, these findings indicate a caution against a rush to policy overhaul to EMI in low- and middle-income multilingual countries.

Language and literacy practices and ideologies of Asian interlingual families in Japan (2025)
This qualitative case study explores the language practices and language ideologies of five mixed-heritage adolescents from interlingual families living in Japan, in which one parent identifies as Japanese and the other is non-Japanese Asian. For interlingual families, maintaining home languages entails significant difficulties and complexities. Furthermore, mixed-heritage individuals in Japan often face discrimination and stereotyping, and little is known about how language ideologies that suppress diversity impact their language practices. Using the lens of family language policy, raciolinguistics, and translanguaging, this study addresses this gap by examining how mixed-heritage adolescents and their families navigate hegemonic language ideologies. One Japanese-Sri Lankan Canadian family, one Japanese-Filipino family, and two Japanese-Taiwanese families participated in this study, and the home languages represented were Sinhala, Tagalog, Mandarin Chinese, Taiwanese Hokkien, Japanese, and English. Qualitative data was collected from multiple data sources and were analyzed using thematic analysis (Braun & Clarke, 2022). The findings indicate that the adolescents engaged in translingual practices with their family in physical and digital spaces, some using English in addition to or in the place of their home languages. However, their language practices were impacted by raciolinguistic ideologies in Japanese society connecting their phenotypical appearance with language proficiency, marginalizing multilingual language practices, and discriminating "foreigners," particularly Chinese people. Members of each family, however, held contradictory beliefs, language practices, and expectations, and negotiated the value and usage of home languages and English within the family. This study also revealed the gendered aspect of multilingual parenting, where mothers accommodated to the father’s language preferences and took on the role of raising the children multilingually. Families, educators, and policymakers can draw from insights from this study to better understand the linguistic environment and development of mixed-heritage children and adolescents and foster their multilingualism.

Preservice early childhood educator perspectives of educator relations with primary caregivers: a survey study (2025)
There is little research about the functional creation and maintenance of effective family and childcare relationships and less about PSECE perspectives on educator relations with primary caregivers. Little is known about what PSECE think about their future work with primary caregivers and how they come to have these perspectives, which may eventually be the basis for their practice with primary caregivers. In light of this context, this exploratory study utilized a survey to gather the views of public post-secondary Preservice Early Childhood Education students (PSECEs) (N=111) in Vancouver, B.C., concerning their perspectives on educator relations with primary caregivers. An analysis of the survey data using SPSS statistical software showed that most participants were born outside Canada. The participants' perspectives on educator relations with primary caregivers mostly aligned with traditional educator-focused interactions. The participants indicated that the Developmentally Appropriate Practice (DAP) they learned in their Early Childhood Education (ECE) coursework significantly influenced their perspectives on educator relationships with primary caregivers. Understanding these perspectives contributes to refining a curriculum that supports PSECEs in developing the attitudes and skills necessary to create and maintain supportive relationships with primary caregivers, fostering optimal outcomes for children in childcare settings.

Teacher conceptualizations of academic writing and genre (2021)
Research has shown that a genre approach to academic writing grounded in systemic functional linguistics (SFL) can give teachers the metalinguistic awareness necessary to deconstruct the language of academic writing. However, teachers require considerable training to gain full control of an SFL-based genre approach, and the influence of this approach is still in its infancy in British Columbia. How then are BC teachers approaching academic writing instruction for ELLs and to what degree has the genre approach made in roads? Informed by SFL-based genre approach to academic writing, this multiple case study addresses this question by investigating 3 BC high school ELL teachers’ approaches to writing instruction to determine 1) how the participants conceptualized academic writing and genre and 2) how their conceptualizations impacted their practice as writing teachers. Data was collected through interviews, classroom observations and document analysis. Thematic analysis was used to develop descriptions of individual cases and to compare and contrast cases. The findings showed that although the genre approach had impacted the practices of all three teachers, only with considerable training did teachers develop a rich conceptualization of genre that could impact all aspects of writing instruction. Furthermore, data also showed that the base level of training required to teach certain ELL courses did not prepare them with an explicit understanding of the linguistic characteristics that distinguish the genres students are being asked to compose.

Written corrective feedback and writing performance: a study of the effects of learner preferences on accuracy development of Iranian English language learners (2021)
Written corrective feedback (WCF) is defined as language teachers’ responses to the appropriateness or accuracy of students’ writing in second language production (Li & Vuona, 2019). Although written corrective feedback (WCF) has been investigated through different lenses, the relation between learner preference to the explicitness of WCF and their performance in writing is scarce in the literature. This quasi-experimental study aims to bridge this gap by studying the impact of learner feedback preference on writing accuracy in text revision in the EFL context in Iran. Sample for this study included intermediate-level students (N=15) from an English language institute. Learner feedback preferences to either direct or indirect feedback were collected through a questionnaire. The same group of students were then asked to complete two writing tasks and received a different type of feedback each time. For the first task, the students received their unfavored feedback type (the type that they did not like) and revised their writings in the classroom. For the second task, the written feedback was adjusted according to their preferred types. The revision was done in the classroom after each feedback cycle. The error ratios of writings and revisions in both sessions were calculated and compared. The results of the paired samples t-test between the error ratio reductions show that there is a significant difference between two sessions of feedback. The large effect size (Hedges’ g=0.87) indicates that the provision of feedback according to learner preferences may have a positive impact on writing performance of language learners. The study has important implications for writing instruction in the EFL context.
