How to Choose a LiveBinder Topic

I am in the midst of preparing for professional development. My current job is to support teachers in grades 1 to 9 with Language Arts instruction. So…I would like to make a LiveBinder on one of the following topics.

*Guided Reading

*Writing

*Reading

*Word Study

I technically should do all, but where do I start.

In Michael Bungay-Scott’s DO Great Work Book, I think I found the answer. He suggests a criteria selection rubric.
