This document summarizes a case study on the implementation of a HyFlex course design for an educational technology graduate course. The HyFlex model allows students the flexibility to participate either face-to-face, synchronous online, or asynchronously. The instructor chose this design to accommodate students' diverse needs and schedules. Students appreciated the flexibility and control over their learning. The case study found that the HyFlex design increased student engagement by giving them options for participation and providing a blended learning experience.
