A one-group pre-test and post-test design was employed within a quantitative research design. The sample consisted of 30 students from class VII C, selected through cluster random sampling. The research instruments included pre-test and post-test vocabulary tests focusing on content words such as nouns, verbs, adjectives, and adverbs. The results of the paired sample t-test show a significant improvement in vocabulary achievement, with the mean score increasing from 55.78 in the pre-test to 82.56 in the post-test, resulting in a mean difference of 26.78. The tvalue obtained (21.492) was greater than the t-table (2.045), and the significance level (p = 0.000) was below 0.05. All aspects of vocabulary show significant improvement, with adjectives and nouns achieving the highest improvement (7.72 points and 11.4 points). These findings highlight the effectiveness of Wordwall.net as a valuable medium for improving vocabulary achievement among Junior High School students.
