My first guest blogger – Dr. David Quinn

I’m pleased to announce my first guest blogger, Dr. David Quinn. David is an Assistant Professor in the Department of Educational Administration and Policy at the University of Florida and is one of the few educational leadership faculty members who truly understands this technology stuff. He used to be an elementary principal and teacher.

David will be blogging the week of September 18, so stay tuned. Thanks, David!

P.S. If you’d like to be a guest blogger one week and share your thoughts about K-12 technology leadership issues, drop me an e-mail!
