Iranian EFL Learners’ Perspectives on New Interchange Series and Top-Notch Series: A Comparative Study

Language learners need to have a number of things at their disposal, namely, effective teachers, well prepared curricula, and appropriate materials. For many learners, textbook might provide the main source of contact they maintain with the language except for the input provided by the teacher (Richards, 2001). Since textbooks are of paramount importance, it deems necessary to improve their quality. The main force of the present paper is to carry out an evaluation on two series of ELT materials namely, Interchange 3rd edition and Top-Notch 2nd. The findings of the study indicated an insignificant difference between the two series.
