Dental and Medical Students’ Perspectives on Early Exposure to PBL in Taiwan

Abstract

A hybrid problem-based learning (PBL) curriculum adopted in 2002 for medical students at China Medical University, Taiwan, was extended to dental students in 2007. Before that, PBL workshops were conducted for all students. Two PBL cases on basic biomedical issues were used for second-year medical students and second-year dental students to explore the feasibility of adopting PBL as part of the dental curriculum. This study compared the medical and dental students' attitudes toward the PBL tutorials and PBL curricula. Upon completion of the PBL component, an eighteen-item questionnaire asked students to assess (on a ten-point scale with 10 as the most positive response) their perceptions of the learning process in the PBL tutorials. Forty-six dental students from a cohort of fifty (92 percent) and 107 medical students from a cohort of 119 (90 percent) completed the questionnaires (fifty-three females and 100 males). The importance of all items was rated above 6.00. The medical students' mean score (7.29) was higher than the dental students' mean score (7.10). Of the eighteen attributes of the PBL process, the students indicated being generally comfortable with fourteen. No statistical significance was found between the dental and medical students' scores, but there was a significant difference (p=0.006) in their perception of PBL curricula. Overall, the medical students expressed a more positive outlook toward the PBL learning process than the dental students and were more willing to accept PBL as a pedagogy.
