Improving Students’ Vocabulary Mastery Using Quizizz at Junior High School in Semarang
Abstract
English is an international language that is essential to master. However, many students experience difficulties in writing due to limited vocabulary, which affects their ability to organize ideas and express meaning accurately. This study examined the effectiveness of Quizizz in enhancing students’ vocabulary mastery and writing abilities, particularly their understanding and application of singular and plural nouns. The research adopted a quantitative approach using a pre-experimental One-Group Pre-Test–Post-Test Design, involving 35 seventh-grade students of Class VII C at SMP Negeri 37 Semarang. The data were obtained through a pre-test, Quizizz activities, a sentence-writing assessment, and a post-test. The collected data were analyzed using descriptive statistics and the Wilcoxon Signed-Rank Test. The results revealed an increase in the students’ mean score, from 89.37 in the pre-test to 99.60 in the post-test. These findings suggest that the use of Quizizz contributed positively to students’ vocabulary development and improved their ability to use singular and plural nouns appropriately in writing activities.
