After giving posttest, the researcher analyzed the data using Independent Sample T-test in SPSS 16.00 because the data were in normal distrbution and the data have same variance or homogenous. From the result of hypothetical test, it was found that the result of Sig. (2 tailed) of t-test for equality of means assumed was 0.000 and α = 0.05. It means that Sig. (pvalue) < α = 0.05. So, H0 is rejected and Ha is accepted. Based on the computation, it can be concluded that there was a significant influence of using Spelling Bee Game to improve students’ vocabulary mastery at the first semester of the eighth grade of SMP N 2 Gadingrejo in the academic year of 2017/201
