The Montessori method is worldwide and it is predicated on common developmental needs of all human beings.
It would be interested in to create a video documentary of children all around the world learning through the Montessori Method, engaged with Montessori materials.
Add a nice soundtrack and keep it a reasonable length and this can be a very interesting video to create buzz and interest in Montessori and to show parents (current and prospective).
Video taping is easy and cheap these days. Most digital cameras and many cell phones can record decent video footage. Video can be sent electronically from anywhere in the world.
All that is really needed is a way to spread the word throughout the Montessori community to get people videotaping, and someone willing to recieve and edit the raw footage.
