An online discussion board can look busy and still function as monologue: students post once, restate a classmate’s comment with different wording, and log off, meeting the participation requirement without producing anything resembling thinking together. This is the most common complaint from teachers moving discussion online, and it is rarely a technology problem. Practice Note 8 in the Teaching in Higher Education series diagnoses why this happens and sets out how to fix it.
Drawing on research into cognitive presence (Garrison et al., 2000), synchronous versus asynchronous participation (Hrastinski, 2008), prompt design (Richardson & Ice, 2010), and learner self-efficacy (Shen et al., 2013; Wei et al., 2023), the note argues that weak online discussion is rarely a student problem; it is a design problem. Format choice, prompt wording, and unaddressed confidence barriers determine whether an exchange produces genuine thinking or compliance.
A worked case study follows a postgraduate public health module through a redesign, from tick-box posting to substantive, cited disagreement, alongside five practical steps: matching format to task, rewriting prompts to demand a position, building in low-stakes entry points, requiring genuine peer response, and following up individually with silent readers rather than penalising them.
Read it before your next discussion board goes quiet.
