“…The SRL strategies EFL learners use to understand how language works through its grammar should, therefore, be well-researched and documented in Vietnam where grammar-based instruction is prelevant (Phung et al, 2021), where the average English score on recent high-stakes exams has been generally quite low (e.g., Duong, 2017;Le, 2019), where English teaching quality is assessed by the pass rate at national high-stakes exams (Do, 2013) and where SRL strategy research is still in infancy (e.g., Nguyen, 2016;Nguyen, 2018). Understanding high school Vietnamese students' SRL strategy use in learning English grammar is necessary and seen to be potentially relevant to many similar ELT contexts in the country as well as the region.…”
