摘要：Communication strategies (CSs) have been receiving ever-growing attention in the areas of foreign language teaching. This study aimed at examining the effects of teaching CSs on students’ oral production in Iranian content-based courses. The study participants were 60 junior high students studying English at SAMA School affiliated with Islamic Azad University. Communication strategy instruction involved eight lessons spread over two months (Week 1 to Week 8) which was undertaken during16 one-hour sessions. The students’ oral production was measured through a series of picture-based story telling tasks. To this end, T-unit was applied to analyze the speaking samples. The results of ANCOVA revealed the positive contribution of teaching communication strategies to the students’ amount of oral production in Iranian content-based courses. Thus, the inquiry provides persuasive arguments in favor of application of CST in content-based instruction. Moreover, teachers will find more efficient methods and activities for explicit teaching of communication strategies.
