This research is motivated by the lack of reading comprehension ability in Cileunyi 07 Elementary School, Cileunyi District, Bandung Regency. Based on the results of observations made in the field showed that the level of reading students' understanding is very low, especially in reading the understanding of short stories. Among them are students are less able to understand the contents of reading that has been read and students can not retell the contents of the text stories that have been read. The problem arises not only from students but also because the methods used by teachers are less effective, creative and fun for students. Therefore, researchers conduct research that aims to determine the process of reading comprehension and to improve the ability to read the understanding of fourth grade students of elementary school. In this research, the researcher use Shared Reading method, the researcher hopes that by applying Shared Reading method, can improve the ability to read comprehension on the fourth grade students of elementary school especially in reading the understanding of short story, beside that the researcher can also know the process of reading comprehension learning by using Shared method Reading. The research method used is Class Action Research method (PTK) by using Elliot design which is done in three cycles, each cycle consists of three actions. In this study the instruments used by researchers are in the form of observation sheet, scoring rubric, field notes, interview sheets, and documentation. Data analysis was done by qualitative technique, quantitative technique and triangulation technique. The average value of the process of reading comprehension ability made by students from each cycle that is on the cycle I: 52, cycle II: 72 and cycle III: 85. While the average value of the ability of reading comprehension obtained by students is on the cycle I: 42, cycle II: 62 and cycle III: 80. Based on the success of the researchers concluded that the application of Shared Reading method can improve students' reading comprehension skills. Therefore, researchers recommend to teachers to use Shared Reading method as one of the solutions to improve the ability to read comprehension.
