Flipped classroom done right can be a great way of taking advantage of technology and allowing teachers to work more individually with students. I don't think it is a good idea for children as lectures aren't the traditional way children learn in a classroom anyway. The only way I could see it is if kids are watching entertaining learning videos at home. I have been using some version of flipped classroom techniques at the University level for over a decade. The idea is that let students do things they can do best alone at home like watch lectures, read etc. and use the classroom time for group work and application of the principles etc while the teacher is available and can walk around and interact with the students and busy students don't have to figure out when they can meet to do group work. I fear this is not how the principle will be applied and will be a disaster for children.
