Background: Biochemistry is very volatile subject. To understand the subject only didactic or traditional lecture methods are not effective now a day. Health professional need to develop analytical and diagnostic thinking skills and not just a mere accumulation of large amount of facts. Hence case based learning (CBL) has been used in the medical curriculum for this reason, so that the students are exposed to the real medical problems which help them to develop analysing abilities. Aims & Objectives: To develop interest and motivate students, to assess the perception of CBL method and to evaluate analytical thinking ability of students. Methods: The present study included 148 students of first year MBBS. Traditional lecture was given to all 148 students and the pre-test was conducted by giving 10 MCQs. Then the 148 students were divided into 2 groups (Group-A and Group- B). Group A- CBL intervention was given (n = 74). Group B- CBL intervention was not given (n = 74). Again, the post test was conducted for Group-A and same MCQs were given. After four months, modified essay questions (MEQs) were given to all 148 students. Results: A 4-point Likert scale questionnaire which contained 10 questions was administered to the students, to know their perception on the usefulness of the CBL. It was observed that majority of students (97%) enjoyed the new method of teaching and developed interest in the subject. It was also observed that the intervention group’s (Group A) perception was improved significantly (p<0.05) when compared with pre- and post-test MCQs. It was also noted from the present study that analytical thinking ability was highly increased in Group-A than that of Group- B (p< 0.0001). Conclusion: CBL is very effective method and it helps in improving not only student’s perception but also analytical thinking ability.[Vaishali P NJIRM 2017; 8(5):67-70]
