“…In that regard, a recent research agenda grounded in sociocultural theory and cognitive–interactionist frameworks has paid particular attention to metalanguage and rule formation exclusively within GI contexts (Azkarai et al., 2022; Mattson–Prieto & Showstack, 2022; Toth & Gil–Berrio, 2022; Toth et al., 2020; Wagner & Park, 2022); such research operationalized metalanguage in terms of rule formation generated through co‐constructed classroom discourse among groups of students and then analyzed the learning process as a representation of metalinguistic awareness. Results revealed that co‐constructed metalanguage among learners is constrained by the level of expertise of the teacher who guides the process (Davin & Kushki, 2022; Wagner & Park, 2022); that it tends to focus on meaning over form (Azkarai et al., 2022; Davin & Kushki, 2022); that it varies according to task design, group dynamics, and individual‐learner agency (Davin & Kushki, 2022; Toth et al., 2013; Toth & Gil–Berrio, 2022); and that it may consist of informal, nontechnical language, variably influenced by the previous metalinguistic knowledge that learners bring to the interactive task (Toth et al., 2020). When considered together, the results leave us with a nebulous understanding of what rules “look like,” how (or if) they are systematically structured, whether they are a result of previous knowledge or induced by GI instruction, and who (among the learners) does (not) possess metalinguistic awareness of a given form–meaning connection.…”
