In the K12 environment, folks are trying to go beyond flipping, and having students engage their parents in the "at home lecture" portion. I tried this with a group of dual enrollment High School students who are earning credit at our University, and it worked out quite well. I assigned them to watch a short <2 minute YouTube video with their parents and then pose a question I provided to their parents and get their answer before coming to class. The lively and very active discussion we had in class about those "kitchen table" talks was fantastic. Very high energy, and I know it was memorable for the students.
How about in pure Higher Ed? Maybe the technology of YouTube might not be possible to count on for discussions with "family and friends" but we could certainly print out a few photographs for them to show and discuss. For Debbie's comment above, perhaps a photo of a clinical skill being performed, on a patient, and a discussion question of "if you were the patient, what would make you say this was performed well or poorly on you?"
