What makes professional development even more frustrating to practitioners is that most of the programs we are exposed to are drawn directly from the latest craze sweeping the business world. In the past 10 years, countless schools have read Who Moved My Cheese?, studied The Seven Habits of Highly Effective People, learned to have "Crucial Conversations," and tried to move "from Good to Great."

With the investment of a bit of time and effort, I've found a group of writers to follow who expose me to more interesting ideas in one day than I've been exposed to in the past 10 years of costly professional development. Professional growth for me starts with 20 minutes of blog browsing each morning, sifting through the thoughts of practitioners whom I might never have been able to learn from otherwise and considering how their work translates into what I do with students.

This learning has been uniquely authentic, driven by personal interests and connected to classroom realities. Blogs have introduced a measure of differentiation and challenge to my professional learning plan that had long been missing. I wrestle over the characteristics of effective professional development with Patrick Higgins (http://chalkdust101.wordpress.com) and the elements of high-quality instruction for middle grades students with Dina Strasser (http://theline.edublogs.org). Scott McLeod (www.dangerouslyirrelevant.org) forces me to think about driving school change from the system level; and Nancy Flanagan (http://teacherleaders.typepad.com/teacher_in_a_strange_land) helps me understand the connections between education policy and classroom practice. John Holland (http://circle-time.blogspot.com) and Larry Ferlazzo, Brian Crosby, and Alice Mercer (http://inpractice.edublogs.org) open my eyes to the challenges of working in high-needs communities.

You're likely to see some more green in the next couple of weeks. Not only on the trees. Very possibly in your wallet, too.
