[Comparative analysis of learning effect for students who experienced both lecture-based learning and problem-based...

Area of Science:

• Dental Education
• Medical Pedagogy

Background:

• Traditional lecture-based learning (LBL) is a common pedagogical approach in dental education.
• Problem-based learning (PBL) offers an alternative, student-centered approach to enhance clinical reasoning and self-directed learning.

Purpose of the Study:

• To compare the educational effectiveness of lecture-based learning (LBL) and problem-based learning (PBL) in a complete denture course.
• To analyze differences in self-study, clinical inference, and student appraisal of course content and tutors between LBL and PBL.

Main Methods:

• A preclinical complete denture course utilized LBL in the 3rd grade and PBL in the 4th grade for the class of 2003.
• PBL involved five cases presented over five consecutive classes, with group discussions and varied reporting requirements (group, individual, presentation).
• A questionnaire assessed the educational impact of LBL and PBL, followed by factor analysis and paired t-tests to compare item assessments.

Main Results:

• Factor analysis identified four key components: study attitude, clinical inference ability, class content appraisal, and tutor appraisal.
• Problem-based learning (PBL) demonstrated significantly higher effectiveness in study attitude, clinical inference ability, and class content appraisal compared to lecture-based learning (LBL).
• Overall, 66.6% of assessed items indicated the significant usefulness of PBL over LBL.

Conclusions:

• Problem-based learning (PBL) significantly improves self-study habits and clinical inference capabilities compared to lecture-based learning (LBL).
• Student passivity in repeated PBL systems necessitates the development of strategies to enhance engagement and learning attitudes.
• PBL shows promise for enhancing dental student education, particularly in developing critical thinking and practical application skills.
