“Some kids use it during tests — they wear a Biodot,” a small plastic dot that changes color as skin temperature (and so blood flow to that area) shifts. This “tells them when they are getting too anxious to think well on the test. If it says they need to, they use the mindfulness to calm and focus themselves, and then go back to the test when they can think more clearly. “The kids understand that when they don’t do well on a test, it’s not because they are stupid, but that ‘When I’m super-nervous it’s in there but I can’t access it. But I know how to focus and calm — then I’ll get to it.’ They have the attitude I’m in charge of myself now — I know what to do that can help.”
