As literacy supervisor for our district of 450+ teachers, I am responsible for our teachers' professional learning regarding anything literacy. It is quite a responsibility with the implementation of the CCSS, and though I have been in education for over 20 years, this is my first year in this position. I am currently planning professional development for our teachers regarding Standard 10 (text complexity) and would love to get your thoughts on my next steps.
People are always asking for common core resources, and today some colleagues put me onto the following sites. I haven't viewed all of the information at these, but there is pretty good stuff on various common core issues like challenging text and close reading. I'm sure you will find these useful.
Also, I took part, with Maureen McLaughlin, in a written webinar today for Education Week (with (Sarah D. Sparks). They have posted the transcript, and that might have some value to you, too.
