One of the more unfortunate buzzwords to appear in online education circles and the press is “flipping the classroom”. This means that instead of lecturing students in lessons in school, the teacher records the lecture as a video and uploads it to YouTube – or recommends other people’s videos to the students. The students watch the videos for homework, freeing up the lesson for interactivity, project work and so on.
