The objective of this study is to prove the effectiveness of using Touch and Go game to facilitate students’ understanding on vocabulary at seventh grade students of SMP Askhabul Kahfi Semarang.
The method of the research is experimental study. The data were obtained by giving test to the experimental class and control class after giving different learning to both classes.
The number of the subject is fifty seven. They are VIIA as control class (the students who were taught without using Touch and Go game) and VIIB as experimental class ( the students who were taught using Touch and Go game).
The instruments used to collect the data were documentation and test. The documentation was used to look for the data concerning matters, such as to get the data of students’ name list and lesson plan. Test was used to know students’competence before and after the experiment run. There are two kinds of test. They are pre test and post test. Before items of the test were given to the students, the researcher gave try-out test to analyze validity, reliability, difficulty level, and the discriminating power of each item.
After the data were collected, the researcher analyzed it. The first analysis are normality and homogeneity of pre-test. It is used to know whether two groups are normal distribution and have same variant. Another is used to prove the truth of hypothesis that has been formulated.
The result of this research showed that the mean of the post test score of the control class (the students who were taught without using Touch and Go game) was 70,34 and the mean of post test score of the experimental class (the students who were taught using Touch and Go game) was 75,00. It showed the mean of experimental class is higher than control class (75,00 > 70,34). On the other hand, the test of hypothesis using t-test formula with standard of significant 5%, shows the value of the t-test is higher than t-table ( 2,252 > 1,67).
