Creative Constructions In Asian And World Englishes - And What They Teach Us, Edgar W. Schneider

Journal of English and Applied Linguistics

"Creative constructions" are defined as patterns which deviate slightly but noticeably from grammatical, fully licensed structures in English (and are therefore sometimes branded as "wrong"), inviting specific cognitive associations to make sense of them. It is argued that such structures offer a window into the nature of the cognitive manipulation of linguistic innovations and change. The concept is related to creativity in literature and lingua franca English, and it is surveyed theoretically by asking how established grammatical theories (like traditional grammar, structuralism or generativism) or more recent approaches to the nature of grammar (usage-based linguistics, construction grammar, and complex systems …

Context-Specific Legitimacy In English Language Teaching: Rethinking Nativeness In The Korean Efl Context, Kenn Arcenal, Teri An Joy G. Magpale

Journal of English and Applied Linguistics

Although non-native English-speaking teachers now make up the majority of the global ELT workforce, perceived nativeness continues to function as an enduring filter in hiring and evaluation. This perspective paper examines how that filter operates unevenly across the institutional sectors of South Korea’s EFL labor market, arguing that Filipino English Teachers (FETs) face a distributive rather than a uniformly ideological inequity, with the biggest disadvantage concentrated in commercially driven private academies. Drawing on two companion studies of FETs working across Korean academic sectors (Magpale & Arcenal, 2025, in press) and integrating more recent scholarship on native-speakerism with comparative evidence from …

Trauma-Informed Esl Ecology: Centering Teacher Well-Being, Equity, And Structural Responsibility In Adult Esl Classrooms, Ghenwa Nasreddine, Heejin Song

Journal of English and Applied Linguistics

Government-funded adult English as a second language (ESL) programs in Anglophone countries increasingly encounter students with histories of trauma, displacement, and structural adversity due to existing and emerging geopolitical conflicts and unsettling sociopolitical realities. These conditions shaping English language teaching (ELT) inevitably influence learners’ cognitive and emotional engagement in language learning, as well as their relationships with teachers and peers. Despite burgeoning literature on trauma-informed practice in ELT, significant gaps remain regarding teacher preparedness, professional development, and institutional support structures to enact trauma-informed pedagogies in linguistically and culturally diverse adult ESL classrooms. Drawing on a critical review of recent scholarship …

Social Complex Systems In Virtual Thirdspaces Of Global Education: Sites Of Structural Inequalities And Radical Pedagogical Possibilities, José Luis Jimenez-Figarotti

Electronic Theses and Dissertations 2020 - Present

While Collaborative Online International Learning (COIL) and Virtual Exchange (VE) are celebrated as democratizing tools fostering intercultural understanding, this techno-utopian narrative obscures a complex reality: the virtual classroom is a contested social field where global inequalities are reproduced and amplified. This dissertation interrogates this paradox, exploring how structural inequalities, digital divides, and epistemic hierarchies are negotiated within the Virtual Thirdspace of global education. Integrating Structural Inequalities (Galtung, 1969; Farmer, 2004; Tilly, 1998; and Young, 2008), Critical Environmental Justice (Pellow, 2018), Intersectionality (Crenshaw, 1989), World-Systems Analysis (Wallerstein, 1974), and Thirdspace theory (Soja, 1996), the study examines this terrain as both a …
