“…Scholars in language education have harnessed SFL as a language teacher knowledge base because of the over 50 years of work developing and implementing pedagogies informed by this theory of language in context (e.g., Byrnes, 2006;McCabe, 2021;Troyan et al, 2021). The theory has been advanced as a knowledge base for teachers of English learners (e.g., Achugar & Carpenter, 2018;de Oliveira & Avalos, 2018;Gebhard, 2019;Humphrey, 2017;Schleppegrell, 2020;Turkan et al, 2014), bilingual learners (e.g., Brisk et al, 2021), and world language learners (e.g., Ryshina-Pankova et al, 2021;Troyan, 2021a;Troyan et al, 2019). Likewise, in the European context, scholars working in content and language integrated instruction (CLIL), (e.g., Llinares & McCabe, 2020;Morton, 2020)-building on Morton's (2016) framework for teacher knowledge for immersion/bilingual education-have advanced SFL as the knowledge-base for teaching in CLIL settings.…”
