“…Therefore, several problems related to gender, age, social class, grammar, vocabulary, functions, gradation, recycling, appropriateness and suitability have been investigated and ways in which they could be overcome have been suggested. There is also evidence that the practice of textbook evaluation gears teachers professional development as it requires using a set of reflective thinking strategies that allow teachers to reflect upon the content of the textbooks to determine the extent to which it is authentic, appropriate and effective (see Ait Bouzid, 2016, Cisar, 2000Cunningsworth, 1996;Hutchinson & Torres, 1994;Jibreel, 2015;Klein, 1985;Litz, 2005;Lu & Lin, 2014;McDonough & Shaw, 2003). Neverthless, textbook evaluation is not merely an intuitive day-to-day passive activity which individual teachers use to superficially skim over the textbook to determine which activities to use and which ones to discard; textbook evaluation benefits both teachers and textbooks if it is employed as a systematic, collaborative and reflective longitudinal practice that seeks to uncover the hidden curriculum that is often obscured by structures, texts and images.…”
