Abstract T he current study was conducted to investigate the effect of enhancing Morphological Awareness on developing English reading comprehension skills of the prep school students. A pre- post experimental group design was used to achieve the study aim. The researcher used the explicit teaching for    promoting morphological awareness of the English language with the students to develop their reading comprehension. Thirty students were randomly chosen from the first prep school students. The study used a morphological awareness checklist and a reading comprehension checklist to determine the required morphological awareness components and the reading comprehension skills that need to be developed by the first year prep school students. Pre/posttests in morphological awareness were also used. Some lessons were reformulated so that they could be explicitly instructed for enhancing morphological awareness to develop reading comprehension of the participants. Analysis of obtained data revealed that the students achieved higher progress on the post administration of the reading comprehension test as the difference in the mean scores of the pre and post administrations of the test were statistically significant in favor of the post administration. Discussion of the findings and recommendations were presented. Enhancing the morphological awareness to develop EFL reading comprehension was suggested for the prep school students.
