GAMIFICATION AS A TOOL TO ENHANCE VOCABULARY RETENTION AMONG UZBEK EFL LEARNERS

Abstract

Vocabulary attrition is a persistent challenge for Uzbek learners of English as a Foreign Language (EFL), especially in input-poor, exam-oriented contexts. Gamification—the use of game design elements in non-game settings—has been proposed as a low-cost way to increase engagement and strengthen long-term retention. This article synthesizes relevant theory (self-determination theory, retrieval practice, spaced repetition, cognitive load, and flow) and prior empirical findings on gamified language learning, and then proposes a rigorous, classroom-ready study protocol tailored to Uzbek secondary and tertiary settings. We outline a quasi-experimental design with pretest–posttest–delayed-posttest measures, specify validated instruments for receptive and productive vocabulary, detail the intervention’s mechanics (points, badges, levels, streaks, adaptive spacing, and quest-based challenges), and provide an analysis plan (mixed-effects modeling with mediation by motivation and practice intensity). We end with implementation guidelines for teachers, anticipated pitfalls, and reporting templates. The goal is to enable evidence-based adoption of gamification that measurably improves delayed vocabulary recall and transfer for Uzbek EFL learners.
