Designing online trainings or courses for large numbers of participants can prove to be challenging for instructors and facilitators. Online learning environments need to be structured in a way that preserves actual or perceived levels of interaction, participant perceptions of value and utility, and achievement of the learning objectives. This chapter describes five Large-Scale Interaction Strategies that offer guidance for addressing some of these online instructional design issues. Evaluation data are presented in support of two of the strategies, and recommendations are provided about how future research in this area might be conducted.
