For the cost of one book per participant, along with perhaps a meal or two along the way, as an educational leaders you can create professional learning communities within your division, school or district. A professional learning community can be as simple as a group of educators committed to reading and discussing a common book. On the other hand, a professional learning community could be a group of teachers or administrators committed to weekly meetings to discuss a book, articles, research, teaching practices and more, over the course of a year or more.
Some of my faculty are beginning a professional learning community centered on a book called Never Work Harder Than Your Students. Elsewhere on our campus other grade-level teams and content departments will be working through Engaging Grammar and Directing the Writing Workshop. While I'm fortunate enough to be at a school where leadership values professional development to the extent that we are not being forced to cut the professional development budget, we see great value in fostering a sense of lifelong learning, gleaning wisdom and knowledge from the educators we have on campus, and generating meaningful conversation amongst our teachers.
