The Effect of Using Online Matching Games on Englishclub.com in Enhancing Vocabulary Mastery at SMPN 19 Bekasi

Abstract

The research investigates the effect of using online matching games on EnglishClub.com in enhancing vocabulary mastery among seventh-grade students at SMPN 19 Bekasi. A quasi-experimental approach with pretest-posttest control group structures was employed. The sample comprised 70 students divided into two groups: experimental (n=35) and control (n=35). Both pre-test and post-test vocabulary assessments were used. The data was analyzed using descriptive statistics, normality tests (Kolmogorov-Smirnov and Shapiro-Wilk), a homogeneity test (Levene's Test), and the Independent Samples T-Test in SPSS. The control class's mean post-test score (68.67) was somewhat higher than the experimental class's (57.33), and the control class's N-Gain Score (mean = 5.17) was slightly higher than the experimental class's (mean = 4.70). The Independent Samples T-Test for the N-Gain Score yielded Sig. (2-tailed) = 0.854, whereas Levene's Test yielded F = 0.461, Sig. = 0.500, demonstrating homogenous variance. The test result was not significant at α = 0.05, with a small effect size (Cohen's d = -.044). These data suggest that, for this population and treatment length, online matching games on EnglishClub.com did not generate a statistically or descriptively significant advantage over conventional education in vocabulary acquisition at the junior high school level.
