THE EFFECT OF LEARNING ENGLISH VOCABULARY BY USING WORD SEARCH GAMES AT SMAN 5 SORONG REGENCY: A QUASI-EXPERIMENTAL STUDY

This study examines the effect of using the Word Search game on students’ English vocabulary mastery at SMA N 5 Sorong Regency. The research applied a quasi-experimental design involving two groups: an experimental class taught with the Word Search game and a control class taught using conventional methods. Data were collected through pre-tests and post-tests. The results of the independent sample t-test showed a significant difference between the post-test scores of both groups (t = -6.095, p = 0.000 < 0.05). The experimental group achieved a higher mean score than the control group. The findings conclude that the Word Search game has a positive effect on improving students’ English vocabulary mastery.
