As an alternative solution to solve different reading comprehension problems in learning English as a foreign language (EFL), it is necessary to implement a blended learning model that combines both online and face-to-face (f2f) teaching modes. This study aimed at investigating the impact of blended learning on Iranian intermediate EFL learners' reading proficiency. Sixty EFL learners were chosen based on their performance on Oxford Placement Test. Then, they were divided into two groups (an experimental and a control group). The experimental group received reading materials through blending learning techniques and the control group received training in the traditional way. During treatment, the teacher designed and assigned activities for students to read the text effectively and reinforce their comprehension. The activities were designed to teach reading like scanning, skimming, and reading for accurate comprehension. Afterward, both groups participated in the reading post-test at the end of the study. The results showed that the experimental group outperformed the control group in the post-test of reading comprehension and the intra-group progress was higher for the experimental group than the control group.
