Taking a positive, generative approach, Brock (education, Creighton U.) and Grady (educational administration, U. of Nebraska-Lincoln) offer all those concerned with educational leadership--principals, teacher leaders, aspiring school leaders, and professors of educational administration--a practical text on how to influence difficult teachers to change their behaviors. The text is based on the authors' experiences as school leaders, a review of the literature, conversations with teachers, and interviews with 50 K-12 principals in public and nonpublic schools. Coverage includes identifying problematic behaviors, reasons why teachers behave inappropriately, solutions and strategies to redirect inappropriate behavior and reduce the negative power it generates, and ways to prevent the development of negative teachers and toxic subcultures by building a culture of shared leadership, collegiality, and team spirit.
