The objective of this study is to investigate the effect of using reciprocal teaching approach in teaching reading comprehension for the second grade students of SMA Negeri 2 Lhoksukon. This study employed a true experimental design in which there were two classes as the sample classified into the experimental and control classes. The experimental group was taught by using the reciprocal teaching approach, while the control group was taught by using teacher centered approach. In collecting the data, test and questionnaire were used, and then the collected data were analyzed by using the computer software SPSSversion 22 to find the t-test score. Before the data were processed into further inferential statistics, the normality and the homogeneity of the data were examined. The results of normality and homogeneity tests showed that the data were normal (sig. 0.20 and 0.12) and homogeneous (sig. 0.63). Based on the t-index maintained from the analysis, it was found that significance difference between both groups is 0.17 which is higher than α=0.05. The finding indicates that the students taught by using reciprocal teaching approach significantly achieved better scores in reading comprehension than those taught by using teacher centered approach. Hence, the alternative hypothesis is accepted and the null hypothesis is rejected. Moreover, the result of the data analysis from the questionnaire indicates that almost all the students responded positively toward the use of reciprocal teaching approach since it effectively improves their reading comprehension skill.
