The document recommends that learners spend at least 50% of their time, and ideally 90%, engaged in "do" activities like student-content, student-student, and student-instructor interactions. It notes that developing games and simulations can be difficult, time-consuming, and expensive, and suggests using existing games or a design team for assistance. Finally, it prompts the reader to brainstorm practice, discovery, and game/simulation activity examples for their online course aligned with objectives.
