Geometer and educationalist Michael Schneider has started a range of classes for young and old at his place in San Anselmo, CA. He writes: "I prefer to facilitate learning by beginning with a youngster's own natural interests. Some interests are fluid, and others lead to ongoing projects in some depth. These classes are not 'tutoring' sessions for the usual school topics although they often involve the same skills used in the context of an investigation. Young people can learn to see and appreciate the excellence of nature and its patterns which teaches many valuable lessons. I approach each subject to promote wonder at the ordinary, the interconnectedness of knowledge and a love of learning in general." Go here for details.
