Although global English Language Teaching (ELT) coursebooks have been subject to numerous (critical) analyses, the changes occurring to their contents over different editions have received scarce attention. In this study, the researchers examined the transformations over different editions of Interchange series (level 2) regarding some selected aspects of their textual contents. Seeking experienced English teachers’ views of the global coursebooks’ transformations over the past decade was another aim of the study. The analysis and comparison of the included topics and titles, characters, sites and contexts in Interchange series as well as interviews with 12 English teachers revealed that the content-based changes of different editions of this coursebook are superficial and cosmetic-like and despite the claims for globality, fallacies such as real-life-ness, representation and globality are still evident. We hope the findings of the study would aid curriculum and policy makers, institute managers, and language teachers to reconsider the functioning and value of current global ELT coursebooks.
