H : There is no significant difference
of the students’ vocabulary achievement after being taught through Pictionary Game.
b. H

V. CONCLUSIONS AND SUGGESTIONS
This chapter describes the conclusions of the research and also the suggestions to other researchers and teachers who want to apply Pictionary Game in teaching
vocabulary.
5. 1. Conclusions Based on the research findings and discussion, the conclusions can be stated as
follows: 1.
There is a significant difference of the students’ vocabulary achievement after the implementation of Pictionary Game. It was proved by looking at studen
ts’ mean score from pretest to posttest, and the t-value. The mean score of pretest
was 65.15, and the mean score of posttest was 89.15. After Pictionary Game was implemented, the students’ mean score of pretest and posttest increased
24 points. Moreover, the students’ increase in noun was 27.5, and the
students’ increase in verb was 21.5. They got higher increase in noun than verb. Based on the calculation through Repeated Measures t-test for SPSS
17.0, it was found that the t-value was 7.199 which was higher than the t-table 7.1992.056. Thus, after the implementation of Pictionary Game, the
students’ vocabulary achievement increased significantly. 2.
By using Pictionary Game, the process of learning vocabulary could be an enjoyable activity for the students. The implementation of Pictionary Game
