Mindfulness in School
The New York Times has an article about some schools in California and Pennsylvania trying mindfulness techniques with their students to help them calm down, focus, reduce stress, learn better, etc. I'm 110% behind this. I took mindfulness classes a few years ago and I can definitely say that the techniques work. I'd recommend them to everyone and anyone - period.
The class I took used the well known book by Jon Kabat-Zinn, Full Catastrophe Living, along with some guided 'meditation' type tapes made by our instructor. The class was taught at the integrated-holistic medicine department of the UCSF Hospital in San Francisco. It's not meditation in the traditional sense. Yes, you do have to sit quietly, but it's more than just sitting there. It teaches you a way to clear the mind and help bring you into the present, which is where you need to be to focus on what you are doing now and what is going on around you - to keep you mind from wandering into the past or future which is where worries and stresses live.
