This new book on Management by Wandering Around is based on the original work of that title by Frase and Hetzel, but informed by numerous new research studies, examples, and experiences as well as several completely new topics and chapters. When the first book was written in 1990, actual research on MBWA was sparse. This new version is based more than twenty well-constructed research studies on MBWA or closely related topics, which indicate that MBWA produces desirable outcomes, including improved student discipline, higher teacher efficacy, and higher student achievement. The New School Management by Wandering Around connects research to practice and includes a new section on classroom walk-throughs using well-defined approaches developed in recent years. Each chapter gives the practitioner smart, research-based advice about what to do in critical school leadership circumstances. The result is a practical guide for teaching and learning the practices of highly effective school administrators.
