By the time I surveyed students on June 4th, we hadn't done "regular" flipped-learning in about three months. Yes, I had assigned some video lessons over the previous few weeks, but circumstances required me to utilize them very differently. The data also got skewed because I only received responses from 44 of my 81 students.
Upon closer examination of the student's other answers, one of the "much worse" responses was apparently more in reference to emergency-remote-learning than to the normal system I had implemented for most of the school year.
I don't think I can learn much from these results.
