A brief summary of some Flipped learning models:
Traditional Flip - synchronous course where students watch videos at home to learn concepts then apply their learning in class.
Mastery Flip - an asynchronous course where students view videos and complete learning activities at their own pace. Note: videos can be watched in class.
Explore-Flip-Apply (EFA) - inspired by the learning cycle and inquiry instruction, students synchronously engage in hands-on exploration of concepts, which are explained in the videos that follow. Students apply their learning after the explore and flip stages. Consistent with "just in time teaching," these videos can be created in response to deficits, questions and misconceptions identified in the explore phase.
Flipped PBL (project) - students complete projects to learn concepts in depth and demonstrate learning. Videos are offered as supplemental aids in completing the projects and/or direct instruction of required content.
Flipped PBL (problem) - similar to the other flipped PBL but the focus of the course is to solve "messy" problems. Students identify concepts they "need to know" in order to solve the problems. Videos and other materials are shared to provide students with the content they need to solve these problems.
Mastery Learning Cycles - inspired by the Explore-Flip-Apply and Flipped Mastery models, students engage in asynchronous learning cycles. They explore concepts before watching videos. After videos, they apply their learning and can choose to demonstrate "mastery" of concepts by completing higher order tasks.
The irony is there is so much diversity within these models and some teachers might even disagree with these definitions. Many of these paradigms are not mutually exclusive, just like the Mastery learning cycle model is a blending of EFA and mastery models. Not to mention, the addition of Standards based grading, student Voice & Choice, Understanding by Design and Universal Design learning can add limitless flavors to flipped instruction.
