Abstract

This research is conducted to know whether group grid technique is effective or not to improve students’ mastery of simple present tense at the eighth grade students of SMP N 19 Purworejo in the academic year 2015/2016.The design of this research is an experimental quantitative research using pre-test, treatment, and post-test. In collecting data, the researcher uses pre-test and post-test. In this research, the researcher takes 61 students as sample from VIII D as experimental group and VIII E as control group. The researcher uses group grid technique to teach simple present tense. In analyzing the data, the researcher employs descriptive analysis and inferential analysis. The researcher uses Mann-Whitney u-test to test the hypothesis. The result of this research shows that group grid technique is effective in teaching simple present tense at the eighth grade students of SMP N 19 Purworejo in the academic year of 2015/2016. It is proven by the result of z-value is 2.88. Based on the 0.05 significance level, the value of z-table is 1,96, the computation showed that z-value is higher than z-table, which is 2.88>1.96. The mean score of experimental group pre-test is 55.23 while the mean score post-test is 79.10. It can be seen from gained score control group and experimental group which is given the treatment. The experimental group score is higher than control group score.
