This study discusses a comparative study of teaching reading narrative text through Story Map and Tree Diagram at the tenth grade of MA Manbaul Ulum Tlogorejo in the academic year of 2019/2020. The purpose of the study were to explain the students reading ability of narrative text using Story Map, to explain the students’ ability of narrative text using Tree Diagram, then to analyze the differences between students ability of narrative text using story map and tree diagram. This study used comparative research with quasi-experiment design (post-test only design nonequivalent groups). The subject of this study was the students at tenth grade of MA Manbaul Ulum Tlogorejo, students’ class X IPA and X IPS. The students from both of the classes had differences treatment which X IPA used a Story Map and X IPS used a Tree Diagram. The technique of collecting data was test and documentation.

After collecting the data, it was found that the mean of students' scores' X IPA using Story Map was score = 87.50, and the mean of students scores' of X IPS was score = 72.83. It was obtained that the t-test was 3.71 and the t-table was 2.067, t-test higher than t-table (3.71>2.067) Ha accepted and H0 rejected. It means that there was a significant difference in learning-result of taught reading narrative text between using Story Map and Tree Diagram.
