I only learned about playlists last year, and at that time I created them in a hyperdoc. I had students who knew a ton about WWII from their previous history class, and I had students new to my school who knew very little. I wanted to have two different self-paced sets of learning activities so that each student was getting the appropriate content for his or her previous knowledge.
I have yet to turn those hyperdocs into Formative playlists (but I will!). In the meantime, I’d like to share a playlist Formative I created for a group of students that I took to Norway last month. For those of you new to playlists, I hope this helps clarify what exactly they are!
