The purpose of this study was to examine the effectiveness of using group story-mapping of English as a second language (ESL) on students with learning disability while reading comprehension. The researcher focused on a specific graphic organizer in this study, called group story-mapping. This strategy required students with learning disabilities involving reading comprehension to identify the five main areas for recording a narrative story: setting, characters, problem, solution, and opinion. This strategy can also help students to visualize the connection between the ideas, and the teachers can have the advantages from the Group Story-Mapping Strategy to determine the strengths and weaknesses of their students while reading comprehensions. Four participants from sixth grade class were selected to participate in this study. This research used a post-test-only design implementing a control group and an experimental group. Three data collection devices were used to determine the effectiveness of using group story-mapping to improve reading comprehension of students with learning disabilities. The result of this study showed that using the Group Story-Mapping Strategy helped students with learning disabilities to comprehend the text more easily.
