This research study focuses on assessing the development of critical thinking of students in POLS 2401-Current Global Issues. The general assumption is that students in this course in particular (and in other social science courses in general) develop a critical thinking/analysis (of global issues) as the course progresses. Based on this, the study focuses on explaining such a development. This study is of particular interest for college/university instructors (professors) who already use or are willing to use critical thinking in their teaching.
