The study investigated the effect of a reading instructional program based on the strategies of successful readers on Jordanian secondary stage students' reading comprehension in English. The participants of the study were 50 first secondary stage male students who were chosen purposefully from the northwestern badia directorate of education. Based on the results of the pretest, two groups were used: An experimental group which consisted of 26 less successful readers who were taught through the instructional program which was designed by the researchers, and a control group of 24 students who were taught the textbook material. The training lasted for two months during the first semester of the academic year 2013-2014. The results of the study showed that there was a significant difference at [image omitted]= 0.05 between the two mean scores of the experimental and control groups in the post reading test in favor of the experimental group due to the teaching strategy. In light of the findings, the researchers presented some recommendations to English as a foreign language (EFL) teachers and the Jordanian Ministry of Education.
