In this informative and insightful scholarly meta-analysis, Divjak, B., Rienties, B., Iniesto, F. et al., shared their research findings pointing enthusiastially at the Flipped Classroom (FC) strategy for active learning.  I have personally implemented this modality in online course delivery and have found it engaging and very powerly guiding the learners to streamline, research, organize, collaborate, and interactively share their problem-solving skills, in both, small groups or individually.  A great read!
