With that thought in mind (since those students are my target audience for this), I am teaching a credit recovery summer school that will be entirely built on a flipped mastery model. I will have students from all four grades (9th-12th) in the same room for five hours a day. We can't use any of the books that are normally taught in the regular year, so we're confined to things we can get digitally for free (did you know that there are lots of Kindle editions of classic books that you can download for free?!) or books that are no longer taught (Lord of the Flies and To Kill a Mockingbird are two, so that's cool).
I've asked my department for help deciding what skills need to be mastered to get a student ready to enter the next grade up, so that should help. But it seems a little overwhelming right now to come up with tasks in reading, writing, conventions, and speaking for four grade levels in a mastery-based model. I asked for 10 hours of planning time, and it looks like I'm going to need that and then some.
Have any of you done something like this? Helpful tips/comments? Bueller?
