USING WORD-WALL TO IMPROVE 11TH-GRADE EFL STUDENTS’ VOCABULARY RETENTION IN A HIGH SCHOOL IN THAI NGUYEN

This study investigates the effectiveness of the Wordwall platform in enhancing vocabulary retention among 11th-grade students learning English as a foreign language at Gang Thep High School, Thai Nguyen City, Vietnam. Employing a quantitative quasi-experimental design, the research involved 46 students over a 7-week intervention period during the spring of 2025. Pretests and post-tests were used to evaluate baseline vocabulary retention and future advancements, while questionnaires record students' views towards Wordwall-based learning. After employing the Wordwall platform, the student’s vocabulary size markedly improved, as seen by the pre-test and post-test results. The post-questionnaire further demonstrated the positive participant assessments of this platform. The researcher proposed recommendations for educators, learners, and institutions derived from the study's findings. Moreover, recommendations for further investigation were offered.
