So far, I've read the FANTASTIC book by Catlin Tucker (@CTuckerEnglish) about Blended Learning and it has given me a great starting point for accessing Edmodo, Schoology, and Collaborize Classroom.
I plan on testing those three over the summer, hopefully to arrive at a decision on what to use in my classroom in September. I also have the option of using D2L, which our school board is beginning to implement in the fall.
This is an exciting time and I can't wait to see where this journey takes me.
