You already know the story of the early European explorers. How they left behind the familiar in order to move towards the mysteries of the new world. Garmston and Wellman will apply the metaphor of the explorer's journey to US schools as they face the unknowns brought about by student/staff demographic shifts, political change, new scholarship and research, and increased use of technology. Just as in Columbus' day, maps are incomplete and archaic "fight or flight" responses interfere with our ability to establish the types of institutions that will be sustainable in the new environment. Garmston and Wellman express that they themselves are actively "exploring" new ways of thinking about schools. Their influences are from quantum theory, constructivist psychology, and personal experiences during years spent as administrators, educators, consultants, etc,.
They take as their basis information gleaned from "the New Sciences." One point is that based on the world revealed by the New Sciences, our world is one where chaos and order are parts of the same system, and that unpredictability, as in weather systems, is a fundamental part of school systems. Another point, drawn directly form the second law of thermodynamics, basically says that all we can do is create school systems which essentially fake control over the chaos. We can establish predictability and order only if we are willing and able to put in ongoing work. They also explore the idea of rejecting unexamined beliefs, values, and assumptions in favor of those that have been illuminated by the light of inquiry. Ultimately all of this has as its concern energy and how it flow or is exchanged within the system. Since schools have to deal with both "things" and "energy," they urge school leaders to pay attention to both, but leaders, as opposed to managers, must deal in energy and become "systems thinkers" if they are to be effective reformers.
For good or for bad, the Adaptive School has enormous amounts of information contained within. The appendix seems like it might be unusually useful. Sometimes though, a single chapter feels so dense that one wonders whether am entire book devoted to the chapter's concepts would be more appropriate. Especially with effectiveness as a central theme, considerations of information overload for the reader might have been a concern for the authors as they structured the books contents. The tables and figures are very useful, however visual learners might get mired down trying to picture concepts which integrate often wildly diverse ideas, as the majority of them are presented textually only. Plus, key concepts can be hard to separate out from the rest, even for readers without any visual preference.
