Chapter authors have all designed their own Hybrid-Flexible courses either as faculty or as instructional designers working with faculty. Their voices and stories provide a rich tapestry that is itself an example of a hybrid (mixed methods) flexible (changing, adaptive) approach to Hybrid-Flexible course design. This list is dynamic – additional chapters are added as they are contributed by those doing the work. (If you are interested in proposing a case report chapter, please see the ongoing call for proposals at the end of Unit III.)
