Yesterday my students took their 1st video-lesson quiz. Yes, I formally assess my students' understanding of the flipped videos. (See more in the "assessment" and "mastery" categories of archived posts.) As expected, nearly everybody passed it. The video is a 3 1/2 minute clip that I recorded in the basement three summers ago. I tell students several ways to reduce distractions (close tabs, use headphones, etc.) and some tech tools to help with watching (pause, reverse, fullscreen). In my first year of flipping, I discovered gradually that some students did not know about these options. They would squint at a 2" x 3" video on the laptop screen instead of enlarging the playback --- augh!! Since 2015, my first formal assessment has been a quiz of understanding about these details.
The only 2 students who did not pass the quiz are also the only 2 who did not watch the video before class. Both are in our most intensive special education program, and both had lied to their teaching assistant about having seen the video. OOPS! Better for them to learn that tough lesson in the 2nd week of school, rather than later in the year. For the other 80 students, I think they learned a good lesson too: watch the video, and you will (probably) pass the quiz. Therefore:
