It Takes Two: Online and In-person Discussions Offer Complementary Learning Opportunities for Students.

Discussions play a significant role in facilitating student learning through engagement with course material and promotion of critical thinking. Discussions provide space for social learning where ideas are deliberated, internalized, and knowledge is cocreated through socioemotional interactions. With the increase of internet-based and hybrid courses, there is a need to evaluate the degree to which online discussion modalities facilitate quality discussions and enhance student achievement. We assessed the effectiveness of asynchronous online discussion boards and traditional face-to-face discussions via qualitative (thematic coding and discussion network analysis) and quantitative (Bloom's taxonomy) techniques and evaluated student perceptions via precourse and postcourse surveys. We found differential strengths of the two formats. Online discussions increased response complexity, while in-person discussions fostered improved connections with course material. Themes related to sharing of personal identity, humanity and verbal immediacy were more frequent throughout in-person discussions. Survey responses suggested that a sense of community was an external motivator for preference of in-person discussions, while anxiety was a factor influencing online discussion preference. Our findings suggest that online and in-person discussions are complementary, and work in tandem to facilitate complex student thinking through online environments and social learning within the classroom.
