Abstract
Case based teaching has shown to improve student perception and comprehension in science courses. However, the existing body of literature lacks direct evidence on its effectiveness in institutions that attends undergraduate Hispanic students. Thus, in an effort to promote the development of analytical skills, we used the "Those Old Kentucky Blues" study and a test to measure students‘ performance and comprehension of Mendelian genetics topic. Student exam scores indicated that when case studies were used, student performance significantly improved in comparison with control groups. Therefore, the incorporation of case study proved to be an effective content delivery method for Hispanic students, improving their perception and performance of the most challenging courses in biology.
