How I Use It
I got to know it in teacher training workshops, have seen other teachers use it and have tried it with some students occassionally.
I find that even though it is great fun it doesn´t actually help learning and goes nowhere to develop learner independence. To me, it is more of a gimmick and one of those activities that Tom Bennet in Running The Classroom describes as games that are remembered more for the sake of the game than for the learning acquired through it. That certainly was my own personal experience when I first tried it in the teacher´s workshop. It was incredibly fun, engaging and... sadly, cognitively empty. In my experience, there are plenty other activities that can engage the students, not actually less caring about making their lives richer rather than my lessons more quick fun based.
