A multiple case study of Vietnamese university students’ perceptions of Quizlet in IELTS vocabulary learning

Abstract

Over the past decade, vocabulary learning has shifted from traditional paper-based methods to digital flashcards with gamification features to enhance engagement. While many studies have investigated the general benefits of digital tools such as Quizlet and Kahoot, few studies have explored students’ perceptions of these tools in Vietnam, especially in IELTS preparation classes. Thus, this study examines the perspectives of three Vietnamese university students from different majors who attended an IELTS class incorporating Quizlet. Findings revealed that Quizlet enhanced learners’ English vocabulary acquisition by promoting autonomy, competence, and relatedness. To effectively integrate Quizlet into Vietnamese universities, participants recommended early exposure, structured digital storage, and assessment via automated feedback to optimize learning outcomes. This study provides insights into the role of technology in vocabulary acquisition and offers practical recommendations for incorporating digital tools into English education in Vietnam.
