In having the iPads I have noticed that an important time to use the flipped classroom concept is on the day of the test.
Students always finish at different times. In the past I have had students sit and waste educational time after they have completed the assessment.
A new practice of mine is to create a short video cast of the next lesson which students need to create on their own prior to the next class period. This has allowed me to use the assessment day to be both a day to assess, but also a day to discover new concepts.
I create a blog post listing items as can be found here. When students are done with the assessment, they simply transition to headphones and their iPad to discover the new concept.
The video cast is below...
