Personal Evidence for the 'Flipped Classroom'

I had explained the idea of the 'Flipped Classroom' to my A2 Chemistry students and the reasoning behind it (I always explain to my students why I do things as I do). Most teachers read the book with the students in the lesson and set questions for homework. I let my students read the book for homework (something they do not need me for) and do the questions in class (something they do need me for). One of my chemistry students looked worried. I asked her what was wrong and she said she could not see what she had done wrong as she couldn't get the answer given in the text book. I went over to her, checked her answer and told her it was correct: the answer in the text book was wrong. She smiled, regained her confidence and was able to carry on with renewed enthusiasm. Had she been doing the question at home, she would have spent hours looking over her answer in order to try and get the text book answer (which was wrong). In addition to wasting valuable time, her confidence would have gone and she would have had a restless night's sleep. If that is not a recommendation for the 'Flipped Classroom' I don't know what is! It is examples like this that add fuel to my cause of trying to convert teachers over here in the UK to my way of thinking and adopting the 'Flipped Classroom' approach.
