The ۲۱st century is the era of revitalizing the key concept of Critical Thinking (CT) followed bytheoretical and experimental studies on CT developments, encouragements, and promotions. Developedcountries studied CT and then operationalized CT development in their educational goals. Despite manyattempts, it seems that there are still countries that do not follow CT enhancement programs. This researchwould suggest that the concept of CT in education needs to be redefined for educational purposes. Theprimary motivation of this research was to provide practical information about CT in locations where CTdevelopments are not encouraged officially and practically. This research reviewed the literature to posefundamental questions in relation to CT and then provide responses. This study ends with answering keyquestions by discussing and summarizing based on the literature and practical suggestions. The implicationof this study can be linked to the educational aspects of different fields of science.
