This Times Higher Education article from Mark Gale highlights the need for designing an interactive online asynchronous experience when building a HyFlex course. The Activeflex name emphasizes this focus on active learning in all modes, especially addressing the online asynchronous path. It’s more difficult to translate a typical f2f course to online asynchronous for many instructors, and without careful design, initial implementation often leads to less online engagement and lower learning, and less student satisfaction. Activeflex aims to correct this shortcoming.
