Flip your classroom : reach every student in every class every day

It started with a simple observation: Students need their teachers present to answer questions or to provide help if they get stuck on an assignment; they don't need their teachers present to listen to a lecture or review content. From there, Jonathan Bergmann and Aaron Sams began the flipped classroom: Students watched recorded lectures for homework and completed their assignments, labs, and tests in class with their teacher available. Bergmann and Sams found that their students demonstrated a deeper understanding of the material than ever before.
