I love this entire article by Jennifer Gonzalez, but her closing paragraph jumped out at me:
Ours is a delicate, nuanced art, and though books and workshops offer all kinds of interesting ideas for how we can improve that art, the resources that lie behind every door in your school can offer something even richer, if you’re brave enough to let each other in.
It’s often too easy to rely on the county, call in a consultant, or “do a book study” for teacher professional development. In nearly all cases, the most effective way for teachers to grow is from each other. That’s impossible without the support, systems, and structures that create the culture for peer collaboration and feedback—as leaders, building that culture is our top priority.
