“…This research differs from previous studies of critical thinking in English as a Second Language (ESL) or EAP textbooks (e.g. Aziz & Talebinejad, 2012;Birjandi & Alizadeh, 2013;Gordani, 2010, Mizbani & Chalack, 2017Sobkowiak, 2016;Talebinezhad & Matou, 2012;Ulum, 2016), because the primary objective was not to assess whether, or to what extent, one particular normative understanding of critical thinking was present, but the objective was to describe the critical thinking approaches that appear in textbooks through a broad lens informed by the theoretical literature. This objective allowed for a clearer understanding of how critical thinking is operationalized in textbooks, and how this operationalization measures against the competing critical thinking approaches found in the theoretical literature.…”
