The emergence of computer technology in English language teaching has paved the way for teachers' application of Mobile Assisted Language Learning (mall) and its advantages in teaching. This study aimed to compare the effectiveness of the face to face instruction with Telegram mobile instruction. Based on a toefl test, 60 English foreign language learners with intermediate level of language proficiency were selected and randomly assigned to the class attendees group, which received the intended treatment program in a classroom environment, and the Telegram group which received the treatment in a virtual environment. Two pre-tests and posttests were administered before and after the treatment. Related non-parametric statistics were applied, and the results were encouraging for the Telegram group. Moreover, the findings of the study might support the claim that innovative instructional approaches and Telegram mobile-learning/teaching specifically could provide new opportunities for the teaching-learning process and that teaching/ learning through new mobile-based methods, Telegram m-learning/teaching in particular, helped Iranian students to perform better on narrative writing tasks. The result of this study would be valuable for methodologists, teachers, and learners.
