The Correspondence between Prospect and Vision Textbook Series in Terms of Content and Based on CLT Principles Delineated in the National Curriculum

The present study investigates the extent to which the principles of Communicative Language Teaching (CLT) have been implemented in the newly-developed English textbooks currently taught in Iran’s secondary programs (Prospect and Vision series). To this end, nine principles of CLT delineated in the National Curriculum and reflected in these textbook series form the analytic foundation of this piece of research. Following that, to determine whether these principles have been appropriately and sufficiently implemented in these textbook series, different sections of the two textbooks were meticulously analyzed. The findings revealed that, contrary to the intentions and attempts made by the textbooks authors, the nine CLT principles are only minimally implemented in the newly-developed textbooks. It was also found that some other principles of CLT are totally neglected in these textbooks.
