Another premise of the flipped classroom model is that in order for students to interact with content in class, they must watch a videotaped lecture on that content before class (courtesy of their teacher or a virtual teacher like Salman Khan). In short, students watch the lecture at home, then work in class the following day on what would have been their homework. Hence the term flipped instruction.
But what if students don't need any instruction? What if they could learn from an activity by simply engaging in that activity? What if lectures are unnecessary, as I asserted at a recent workshop for new teachers?
