To let this kind of learning happen, takes a instructor who is willing to take a step back and allow the students to take control. The instructor may prose the question but from there the students will carry out the learning process themselves. I am keen to try this approach and can see it working well with the Anatomy and Physiology aspects of Esthetics. Students would be asked to chose a body system and teach the class how that system interacts with the skin. They are free to learn anyway they wish and present their lesson in class time. Class time could also be used to look at skin cross sections under a microscope and in depth discussion on how systems in the body work together.
I have included the link to Mr Sugata Mitra's TED talk for viewing and a link to his
SOLE - Self-Organised Learning Environment.
