Is there Momentum in Self Directed and Peer-to-Peer Education?

I was always fascinated but skeptical by this idea of self-directed learning. I still believe that nothing can have as large an impact on the delivery of primary education as a motivated and passionate teacher/coach. The part of this video that excites me the most is the peer-to-peer aspect or the "showing off" aspect. The comined power of self-direction plus peer-to-peer/social is a bet that I would like to put a stake on with any online education ideas that I develop.
