Abstract: This study examined the longitudinal development of English vocabulary retention among 44 eighth-grade EFL learners at a lower secondary school in Vietnam over a 16-week instructional intervention. Grounded in the action research framework of Kemmis and McTaggart (1988), the study integrated Liveworksheets as a supplementary retrieval-based practice tool within the Practice stage of the Presentation-Practice-Production (PPP) pedagogical framework. Vocabulary knowledge was measured at five time points using a modified Vocabulary Knowledge....
