The data for this study were obtained by using test as the instrument for collecting the data. Also, the data were analyzed using repeated measures T-test in order to prove the hypothesis. The calculation result showed that null hypothesis (H0) was rejected and the alternative hypothesis (Ha) was accepted, because the result of t-test calculated was 5.07, higher than t-table 2.04. Therefore, the writer concludes that teaching reading by using KWL gives good effect for students’ reading comprehension at SMPN 3 Banda Aceh.
