An Evaluation of a Microlearning Intervention to Limit COVID-19 Online Misinformation.

As part of a design-based research project, we designed, developed, and evaluated a web-based microlearning intervention in the form of a comic into the problem of COVID-19 online misinformation. In this paper, we report on our formative evaluation efforts. Specifically, we assessed the degree to which the comic was effective and engaging via responses to a questionnaire ( n  = 295) in a posttest-only non-experimental design. The intervention focused on two learning objectives, aiming to enable users to recognize (a) that online misinformation is often driven by strong emotions like fear and anger, and (b) that one strategy for disrupting the spread of misinformation can be the act of stopping before reacting to misinformation. Results indicate that the comic was both effective and engaging in achieving these learning objectives.
