Case study pedagogy is a teaching strategy in which teachers hope to help students develop and use critical thinking (CT) abilities. This study compared CT skills of 75 second year generic accelerated baccalaureate nursing students during their Fundamentals of Nursing course before and after being educated using case study pedagogical method. Through the use of a standardized CT (HESI) exam, taken at the beginning and the end of the course, scores were compared for improvement using paired t-tests and a one sample t-test. The results demonstrated that the HESI CT test scores identified a statistically significant difference with a larger average score after the intervention of the integration of the case study teaching strategy as compared to the pre-intervention average. The findings have implications for educators to help students develop insight into the usefulness of case studies as a teaching learning method to foster students' CT skills.
