1. Be the change. Leaders of professional development seem to forget that they’re actually teaching, and that part of teaching is modeling the activity you hope to see adopted. A session devoted to equipping teachers to implement more collaborative learning that is presented via “death by PowerPoint” is an oxymoron, a term originating from a Greek word appropriately meaning “pointedly foolish.” As one teacher recently expressed it, “Why does the worst teaching often happen in sessions on how to improve teaching?” Why, indeed? Modeling is a powerful teaching technique. In addition to communicating that the suggested new approach promotes learning, demonstration taps into some of the brain’s natural learning systems: This may be because demonstration actually encourages the brain to engage. Specialized neurons known as mirror neurons make practicing “in the head” possible…When a teacher repeatedly performs a sequence of steps, her students’ mirror neurons may enable their own preliminary practice of the same steps. In other words, as a teacher demonstrates a skill, students mentally rehearse it.1

Though we’ve been invited to lead professional development, we do not have all the answers. Professional development involves merging new research findings with current personnel—i.e., bringing ideas and people together. One way I’ve tried to do more of this recently is to ask teachers if any of them have tried something similar to a new approach I’ve explained. If any have, I invite them to share their experience. This invites elaboration, a critical cognitive process for constructing understanding. If the teacher’s experience was positive, we discuss why the approach was successful. If the teacher’s experience was frustrating, we often find together the reason for it and develop a plan for structuring it better the next time. This give-and-take values everyone, respects the experience present in the session, and allows the leader to be a colleague rather than an aloof expert.

2. Listen. I have a tendency to get preoccupied with my preparation and forget that I’ll actually have people in the professional development session. Not just people but colleagues!

In Gatsby's Tracks: Locating the Valley of Ashes in a 1924 Photo

Desolate enough? The sight of workers toiling among these giant piles may have even reminded Fitzgerald of Dante, and Fitzgerald's real-life encounter with this spot must have played a part in the genesis of the entire novel.

If Gatsby's caravan took this southern route, the railroad and highway would have merged exactly as described in the novel. Here, then, is the bridge they would have crossed. I can't tell for sure that it's a drawbridge, but I'm willing to believe it must be one. The tiny settlement to the right, then, is exactly the spot where Dr. Eckleburg's billboard would have stood, and where George Wilson would have kept his auto garage.
