What is a flipped classroom?
According to Jonathan Martin, a flipped classroom is described as, "Flip your instruction so that students watch and listen to your lectures... for homework, and then use your precious class-time for what previously, often, was done in homework: tackling difficult problems, working in groups, researching, collaborating, crafting and creating." (Gerstein, 2011)
Basically, a flipped classroom is when students watch instructional videos outside of the classroom. In-class time is used for application. Students work on various activities that require them to apply the skill learned at home.
How did flipped classrooms get started?
Flipped classrooms began as the "Fisch flip." Colorado math teacher, Karl Fisch, began video-taping lectures and assigning them as homework. Daniel Pink made Karl's method known as "flip thinking" or the "Fisch flip." (Watters, 2012)
Even though Karl Fisch made flipped classrooms popular, he was not the original started of them. In the 1990s , Harvard professor Eric Mazar started the idea of peer instruction. This changed his teaching practices to less lecturing. Then, in 2007, Jonathan Bergmann and Aaron Sams, two chemistry teachers, began recording their lessons. (Watters, 2012) They discovered a software that recorded their PowerPoint presentations. They recorded and posted their live lectures online for students who missed class. (Strayer, 2011) Recently, the Khan Academy has made flipped classrooms gain press and credibility in education. (Gerstein, 2011) The Khan Academy popularized the term "flipped" classrooms. (Watters, 2012)
