The result showed that the students who learned by using CORI got higher score than those who did not. It could be seen from the result of independent sample t-test of students’ post-test between experimental group and control group, the t-obtained in equal variences assumed was 2.385, and the significant (2-tailed) was 0.023. Since t-obtained was higher than t-table (2.385 > 2.036) and the significant (2-tailed) was lower than computation with level significant (0.023  < 0.05).

Mastery of Arabic vocabulary is the main key to success in learning Arabic. By using media as a bridge in distributing material, it will change the mindset of students who think learning Arabic is difficult to understand. At MI Muhammadiyah Sribit, the conventional Arabic learning process inspired researchers to conduct experimental research on the use of word hoop game media to know the differences in students' Arabic vocabulary mastery between the experimental class and the control class. This study uses a quasi-experimental research type with a quantitative approach. The research subjects were students of class IV A as the experimental class and students of class IV B as the control class. The process of collecting data using test results, observations, and interviews was then analyzed using the paired-sample t-test and independent-sample t-test with the help of SPSS. From the results of the study, it was found that the results of the application of game media in learning Arabic can improve students' vocabulary mastery. Based on the results of the independent sample t-test, the posttest significance value in the experimental class was 0.008 < 0.05, and the posttest value in the control class was 0.009 < 0.05. So it can be concluded that there is a significant difference between the mastery of Arabic vocabulary for the experimental class and the control class.
