One of the organizational characteristics used in the Minnesota School Effectiveness Program is a positive school climate, which includes collaborative planning and collegial relationships. This module begins by identifying four types of collegial practices that characterize successful schools: (1) frequent, continuous, and increasingly precise talk about teaching practice; (2) observation of teaching with useful postevaluation conversations; (3) teaching materials that are planned, designed, researched, evaluated, and prepared by teachers working together; and (4) staff members teaching each other instructional procedures. A short summary of research is included that shows the relationships between staff members and between staff and administration to be a determinant of a climate favorable to continuous improvement of instructional practices. Fifteen implementation suggestions are then provided, along with instructions and instrumentation for (1) an activity to promote positive feedback, and (2) a staff interaction survey. A short bibliography is also included. (TE)
