There is no ONE flipped classroom model but rather many variations of it. More correctly it can be viewed as flipped learning.
The big question to ask yourself is : What is the best use of your time in the classroom?
The flipped classroom is about finding the best way to maximise your effective classroom time. Creating videos is not an essential element although many use this approach to varying extents.
Flipping Blooms – low end tasks at home & higher lever interactions and creation at school.
A flipped classroom model maximises learning opportunities – it caters for individualised learning, allowing students to progress at their own rate while freeing the teacher to interact more with those students who require assistance. It gives students more control of and more responsibility for their own learning.
Front loading static, procedural and admin type instruction creates a launch point that allows teachers to use classroom time to evaluate and collaborate. Front loading should also be used to challenge students and prepare them for classroom activities.
Doesn’t have to involve video, only make a video if that is the most effective way to convey the material, especially don’t re-create something that has already been done. Allow students to create their own videos for whole class use, if appropriate.
Encourage students to do their own informational research beyond whatever you have created.
Flipping PD for teachers allows them to access material when it suits them.
Flipped Classroom is a technique and not a pedagogy that in practice can look however you want it to look but it must be a student centred approach that translates into more effective teaching and learning opportunities.
