OBJECTIVE: (l) To identify the attitude of students towards learning of basic medical course (Biochemistry) in innovative curriculum with PBL as the principle mode of information transfer, (2) To compare the university results of the students trained through two curricula. STUDY DESIGN: A cross-sectional analytical study. SITE AND DURATION: Jinnah Medical and Dental College, Karachi during the academic year 2003 – 2004. SUBJECT AND METHODS: Fifty-four students of batch -4 were asked to fill an anonymous questionnaire regarding 30 PBL sessions they were exposed to, during the academic year March 2003 till January 2004. The responses were analyzed using Chi-Square test. The results of first professional part B MBBS annual examination conducted by university of Karachi for batch - 3 (n=71) & 4 (n=54) were compared using student`s t-test. Statistical analysis was done using SPSS version 10.0. RESULTS: Significant number of the students found PBL as a useful study aid and agreed that basic science knowledge is applicable and can easily he correlated with the clinical science knowledge (87% & 79.62%, p<0.05). These sessions helped them to internalize habit of giving evidence-based answers and enabled them to acquire habit of doing positive criticism in group-discussions and to tolerate it patiently (88.8%, 87%, p<0.05). Them was significant difference between the results of two classes exposed to conventional and problem-based curricula (p<0.05), probably it is due to the method of examination, which is totally conventional. CONCLUSION: The study results strongly favour introduction of problem-based learning as the mode of information transfer in basic sciences, but it should be implemented in combination with the traditional learning methods to provide effective training to the undergraduate medical students.
