I saw a segment on NOVA tonight that has some interesting implications in how we teach and learn: Mirror Neurons. My basic understanding of this theory is that when we watch someone else do something, neurons in our own brain mimic the activity needed to accomplish what we are seeing. They used the example of watching someone struggle carrying too many heavy packages. When we see them we vicariously live it out ourselves, trying to balance the packages for them. I have seen another example of this when someone feeds a baby. Often the person feeding will open their mouth as they are spooning in the mashed carrots, as if eating for the child.

I think it provides evidence for the value of observation when trying to learn a new skill, and also when trying to improve a skill. Observing is more than just "seeing how it's done" - it is already a form of rehearsal.

Also, Danial Glaser, the researcher interviewed, talks about how there is greater "resonance" of neural activity when you see something performed that you have physically performed yourself. You have a greater capacity to perform it cognitively while watching. So this might suggest the need to alternate between observation and practice.
