摘要:Action research designs are systematic procedures used by teachers to gather quantitative and qualitative data to address improvements in their educational setting, their teaching, and the learning of their students. Action research enables teachers to keep track and take account of the many aspects of their work with students through a systematic routine. This study aims to investigate the critical reading strategies employed by Iranian EFL students. To achieve the aim of the study, the Stringer’s Action Research Model that is a cyclical and repetitive process of inquiry i.e. Look, Think, and Act was utilized. This study used Bloom’s taxonomy as useful reference tool to describe the ability of thinking simply for high school EFL students.
