Article Authoritative discourse in a locally-published ELT textbook ...
I like this article because it is methodical and systematic in its use of theory and empirical data. But I see a limitation in the discussion section as the authors seem unable or unwilling to connect the problems with this text/class/pedagogy with the larger context of Western power and colonial rule. Interestingly, while the use Pennycooks' earliest book, the did not use his English and the Discourses of Colonialaism, which deals with these issues in great depth.
This omission is important because it would be difficult to correct the shortcomings discovered by the authors unless this larger context is factored in.
In theoretical terms, attempts to address the concerns raised in this study will likely engage in "problem solving theory" not "critical theory" (Cox).
