This paper presents a case study of developing a blended reading program for Korean EFL middle school students using a process drama methodology to generate intrinsic motivation to read, improve reading comprehension and language fluency, and foster twenty-first-century skills such as creativity, communication, and cooperation. For the development of the reading program, a needs analysis was conducted using student questionnaires and diagnostic tests. From results of the needs analysis, sample lessons were designed based on the process drama methodology following its planning principles and strategies. Based on feedback from teachers and students after piloting the sample lessons, the blended reading program was finalized. The proposed blended reading program is expected to help Korean EFL middle school students build a positive attitude toward reading English books and develop reading comprehension, language fluency, and 21st-century core competencies. It will also encourage English teachers to use innovative teaching methods in English education.
