Go to school - sit in class - go home - study.
This traditional teaching method is now being challenged. The Learningpyramid shows that lectures provide the lowest learning outcome, while students teaching each other provides the highest learning outcome. This doesn't mean that we should all stop lecturing, but sometimes other various teaching methods can provide better learning environments and thus higher learning outcomes for the students.
Flipped learning is a pedagogical approach in which direct instructions moves from the group learning space to the individual learning space, and the resulting group space is transformed into a dynamic, interactive learning environment where the educator guides students as they apply concepts and engage creatively in the subject matter.
Flipped Classroom in 60 seconds:
Even though many teachers probably have been flipping their classrooms for a long time, the pioneers of the Flipped Classroom movement are Jon Bergmann and Aaron Sams. They both worked as teachers in high school and felt frustrated over having to repeat lessons for the students who missed classes, stealing valuable time from all the other students. They decided to start videorecording lessons so that the students who missed class could watch them at home, and it turned out that students that had been present in class also watched the recordings to either strengthen what they learned or to better understand complex theory.
