The flipped classroom has been one of the main educational trends of the past year or so. The idea is to move the input sessions to net-based videos that can be watched at home and spend class time on discussion, practice and feedback. Teachers can either record their lectures and demonstrations or use other teacher's material that is available as open educational resources. It means that class time is used for real contact between students and teacher and not for one-way communication.
