THE EFFECT OF WORDWALL MEDIA ON STUDENTS’ VOCABULARY MASTERY AT THE ELEVENTH GRADE OF MA AT-TAQWA YASTU

Abstract

Vocabulary mastery plays a vital role in students' overall English proficiency, yet many learners struggle due to monotonous teaching methods and limited motivation. This research investigates the effectiveness of Wordwall—a game-based interactive media in enhancing vocabulary mastery among eleventh-grade students at MA At-Taqwa YASTU. The study employed a quasi-experimental design involving a control and an experimental group. A pre-test and post-test were conducted to evaluate students’ vocabulary mastery before and after the treatment. The findings revealed a significant improvement in the vocabulary scores of the experimental group using Wordwall media compared to the control group. The results were supported by statistical tests showing normality, homogeneity, and a very large effect size (Cohen’s d = -4.034). The study concludes that Wordwall is a highly effective and engaging tool for improving vocabulary mastery, fostering active student participation, and enhancing learning outcomes.
