OK, so the more I think, the more I feel the need to get my definitions of "interactive notebook" and "flipped classroom" out there... so you know where I'm coming from.
Interactive Notebook: a place where students can take information from the teacher and merge it with their own thinking. It's usually done in a spiral notebook with a "left side" and a "right side." On the right side, students write down the info from the teacher, whether it be plain old notes or a handout, graphic organizer, foldable, etc. glued right into the notebook On the left side, students record their own thoughts about the information to demonstrate understanding. There are lots of recommendations as to how to set it up (skipping the first few pages, numbering pages, gluing pockets at the front/back of the notebook, etc.), but to me, that's "interactive notebooks" in a nutshell.
Flipped Classroom: So I'm totally stealing this from the tech integrator in my district.
"The Flipped Classroom model of instruction means that instead of lectures occurring in the classroom and assignments being done at home, the opposite occurs. students watch videos at home that "teach" or deliver the content. Then, in class, they work with the information in class, therefore getting more teacher assistance with the higher level application of the information."
Sara has an awesome website HERE to learn more! She's basically taught me everything I know about flipped classrooms (not like I know a ton...), so I might as well direct you straight to the source :)
These are my working definitions of these two terms. If I'm missing something or totally off-base, let me know :)
