Understanding how to structure the “Statement-of-the-Problem” (SP) section of a thesis is necessary for EFL students to develop a logical argumentation for a problem statement. This study intended to compare Move structures of SP sections of theses written by native speakers of Persian (NSPs) and English (NSEs). To this end, 100 SP sections (50 SP sections written by NSEs and 50 written by NSPs) of theses in the field of English language teaching (ELT) were selected and analyzed by the researchers based on Swales' (1990, 2004) CARS models. The analysis of the data revealed that Move structures of SP sections of the two corpora were similar. In both corpora, the three Moves of “Establishing a territory”, “Establishing a niche”, and “Presenting the present work” were considered obligatory. There were some differences in the Steps and many Move pattern variations in the two corpora. The results can broaden the understanding of the nature and function of this genre and can have important implications for EFL instructors.
