Typical Teacher Network

So we as professionals are required to stay up to date and own our professional development.  What tools and resources do we have in our disposal for this?

With our PLCs we multiply what is available in our "network" because we are bringing in different individuals.  But at least some of the learning resources of your "teammates" are identical to your resources.

How do we prevent the bubble from forming then? How do we realize if what we are doing is even as good as it could be or the right thing to do?
