Here are some suggestions on how to get started from a recent Education Week teacher blog:
Response: Several Ways Teachers Can Create A Supportive Environment For Each Other
Our school culture has a growing sense of [unhealthy] competitiveness. I believe a lot of this stems from the fact that our administration does not recognize (or maybe they do and simply don't voice) teacher expertise using specific, positive praise. We do receive thanks yous - but they tend to be blanket statements and pretty general. (For example, "Thank you Ms. _____ for helping your team out.")
Anytime that we try to assign numbers to individual teachers--rather than recognize that improvements in student performance come from collective reflection around practice AND the collective contributions of all of the practitioners that work with a group of children--competition is inevitable.
When your team stops talking about teachers and starts talking about teaching--or more accurately, student learning--you'll begin to erase the competition and defensiveness that is destroying your collaborative work.
