Woes of an RCT for Game-Based Learning Research - Past Problems and Potential Solutions

Randomized controlled trials (RCTs) are the gold standard for scientific research but pose many obstacles for game-based learning (GBL) studies. This poster is intended to foster a discussion about RCTs by summarizing two recent trials performed by the authors and comparing the distinctly different protocols including length of stimulus exposure, levels of internal and external validity, and sample size considerations. Finally, a proposed protocol for a third RCT is presented that attempts to reconcile the pros and cons from the previously described studies, while maintaining rigour in the research - the authors seek feedback from conference attendees as to the protocol's viability.
