With these purposes, the study firstly presents relevant theories about the instructional design, e-learning strategies, second language acquisition, and English teaching theories to investigate on what theoretical foundation the MEDT was developed. It then examines how the MEDT integrates and incorporates new technologies such as speech recognition, automatic writing scoring system, games, flash animation, and digital storytelling into a wide variety of English learning activities such as listening, speaking, reading, and writing. Thirdly, the study reports the learners" and experts" evaluations of MEDT with respect to contents, learning activities, interest, levels, and technological functions. Lastly, based on the evaluation of the MEDT, some suggestions are made on the effective use of MEDT for the implementation of enhanced, high-technological, and motivating English learning environments in Korean elementary schools.
