It is aimed at finding out whether or not there is effective. This research is called a quantitative research with an experimental design. In this research, the population is the seventh grade students of SMP N 6 Purworejo with the total number of population is 192 students. The sample of this research is 64 students, they are 32 students as control group and 32 students as experimental group. The researcher took the sample by using purposive sampling and the instrument which is used to get data is vocabulary test. The techniques of analyzing data are descriptive statistics and inferential analysis use SPSS 16.0. The researcher analyzed the data using descriptive statistics to find mean, median, mode, range, standard deviation and variance, whereas inferential analysis is used to prove the hypothesis test in the significance level 0.05. The result of t-test based on the computation of SPSS 16.0 show that t-value < t-table (-5.387<-2.000) and p-value<α (0.00<0.05) at the 95% confidence interval of the differences. It is significance because the Sig. (2-tailed) is lower than 0.05 (0.00<0.05). In addition, the result of the analysis data shows that the mean of score pre-test control group is 68.63 and the mean of score post test control group is 73.75. The increasing score is 5.12. Besides, the mean of score pre-test experimental group is 74.63 and the mean of score post test is 81.13. It is increasing of score was 6.5. Based on the mean score of both of group, it is clear that the mean of the post-test experimental group was higher than the means of the post test of control group.
