This project examines both the impact of a metacognitive instruction on L2 learners’ task engagement and the methodological consequences of alternative statistical model specifications in a quasi‐experimental context. The findings contribute to the ongoing methodological innovations in instructed second language acquisition (ISLA) by (a) empirically evaluating the efficacy of metacognitive instruction, and (b) identifying optimal analytic approaches for causal inference in short time series, longitudinal intervention research.
