INGGRIS:
The aims of this study were to described the implementation of Rainbow card in improving students’ reading comprehension of descriptive text and especially Finding Main Idea, Making Inferences, and Using Vocabulary Knowledge for Effective Reading to find out the significant difference between the student who are taught by using rainbow cards and students who are not taught by using non rainbow cards of eighth grade students at MTs An-Najah. The population in this study was all the eighth grade students of MTs An-Najah with total number of students 60. In this research, the researcher used census sampling or saturated sampling. While for the sample, the researcher took eighth grade students as samples. All samples of both classes were 60 students. The instrument used were observation, test, and documentation. Based on the independent sample t-test, it was found that the mean difference between post-test in experimental and control group was 10.267, and the standard error difference was 1.757. Then, the significant (2-tailed) was .000, t-obtain was 5.845, critical value of t-table was 2.02 and degree of freedom was
58. Since the p-output or the significant (2-tailed) was .000 lower than computation with level significant 0.05, and t-obtain 5.845 was higher than critical value of t-table 2.02. Therefore, the alternative hypothesis (Ha) was accepted, while the null hypothesis (H0) was rejected. It could be concluded that there was a significant difference in post-test between students who were taught by using rainbow card and those who were taught without using rainbow card. It could be concluded that there was a significant difference in post-test between students who were taught by using Rainbow Card media and those who were taught without using Rainbow Card media.
