Abstract

• Nowadays, many ELT teachers, educators and other subject teachers are aware of the need to integrate 21st century skills, especially critical thinking, in their lessons. Thinking practices can encourage students in their participation in classroom activities and help them survive in the challenging world. Therefore, the present study was carried out with the purpose of evaluating the extent of thinking skills that the instructions in the English coursebook call for. The study investigated the levels of thinking skill called for by instructions in the coursebookglobalB1. The instructions in the coursebook were gathered, analysed and categorized according to the cognitive domain of Bloom’s Revised Taxonomy (2001). The results of the study showed that 63.95 % of 860 instructions called for lower level thinking, whereas 36.05% of them demanded higher level thinking skills. The results of the study implied that if ELT teachers wish to promote students’ thinking skills and to help them survive in the challenging world, they need to incorporate thought-provoking tasks into their lessons.
