Abstract
Online discussion boards may enhance critical analysis and reflection, and promote the acquisition of knowledge. To assess the effectiveness of online discussion board as a pedagogical tool in augmenting face-to-face teaching in dental education. Data were collected from a discussion archive offered through the E-course website of the School of Dentistry, University of Birmingham, UK in 2008. A multi-component metric included; participation, social learning, cognitive processing, role of instructors, and quality of discussion. Messages were coded for 14 variables to evaluate these dimensions. Data were analyzed using content analysis methodology and a complete message was uses as the unit of analysis. There were no significant difference in participation between students and instructors (P<0.05). Social interaction with peers appeared only through students posting messages with open questions (27/135 messages). The discussion board was mainly used by students to understand concepts (27/102 messages) and apply procedural knowledge (17/102 messages). Instructors were mainly replying to students' messages with (49/120 messages) or without (54/120 messages) proposing another action. Online discussion boards were found to be successful pedagogical tools in dental education. Further development of instructor-led discussion approach is needed to promote higher level learning and collaborative thinking.
