Are teachers really the best teachers?

I had the pleasure of observing this in my classroom the other day.

We have been working on rereading our work and checking for errors and then correcting some of those errors independently (refer to earlier post to read about our proofreading wall). The girl on the left had recently figured out how to use a dictionary to proofread and edit her work (with great success). She has now become one of our dictionary experts. When ever the children are stuck or don't remember how to use the dictionary then she is one of our go to people.
While I was working with a group I saw these girls engage in the above learning conversation. Thinking that this is gold I quickly grabbed my phone and started filming. I would have loved to have shown more but because I was trying to be sneaky one of children didn't see my phone on the ground and sat in front of it, thus ending this impromptu filming session. What you don't see, is the girls working together to find a number of words successfully. The little expert scaffolded her buddy, taking her through step by step and then slowly handing over control to let her achieve success independently.
There are times that we teachers just can not give one on one lessons to our students even though they need them. I think having class experts in a great way to give that one on one tuition to those who need it. This approach also helps the experts become proficient at the skill they are using.
In my view it's a win, win!
