Educators have recently begun using digital breakout games as an instructional strategy in K-12 and higher ed curricula. However, research has thus far explored outcomes associated with playing these games, rather than designing them. This study investigates what happened when 23 preservice teachers in a technology integration course designed digital breakout games for the secondary curriculum. By conducting a basic qualitative analysis, we found that digital breakout game design promoted skills, competencies, and perspectives in support of preservice teachers' future practice such as TPACK development, 21st-century learning, and positive technology integration perceptions and intentions. We provide evidence and implications for these findings, as well as opportunities for further research.
