I have been looking for ways to increase collaboration and provide teachers with authentic opportunities to lead and learn from one another. This year I introduced POP Teams (Peer Observation Partnerships), and for the first half of the year they seemed to work well. One of the biggest drawbacks of POPs was teachers wanted to collaborate with more than just their chosen parter. I also noticed the level of peer coaching wasn't where I would have liked it to be, and the number of instances where teachers went in to visit another classroom was small. One day, as I was looking on Twitter, I came across Mark Barnes' Pineapple Chart blog post. I began reading up on this, and approached you principal about possibly implementing this next year.
