Flipping classrooms is a learning and teaching approach most relevant to secondary and tertiary schools although, when appropriate, it can also apply to elementary or primary classes. The premise is that the content necessary for success in a particular quest is learned outside of school hours and then applied at school to complete a project, task or line of inquiry.
The beyond-school learning is accessed through podcasts, set readings and online research. The teacher's role is to facilitate and support the application of that learning to task completion in the social context of the school.
A restriction of this model is that, if it is the sole mode of learning, it is too inflexible. A more desirable reality is to keep the distinction between gaining and applying knowledge and skills but not delineate when or where they happen, either at or beyond school.
Also, the skills needed to undertake an application task are often not fully identified until attempts at the task have been made; and these will differ according to the different skill levels of students.
Allowing access to a school's multi-media resource centre on demand allows it to function optimally, allows flexibility, and helps blur the distinction between school and home.
