The primary objective of the Stallings Classroom Management Staff Development Model is to help teachers change so that they can manage their classrooms more effectively. In this model, classroom observations and specific recommendations for teaching behaviors are made for each teacher, and a series of teacher training sessions helps them to change their behaviors. Classroom observation data are collected at the conclusion of the training sessions, and teachers receive profiles showing results of their efforts at changing. This model uses the Secondary Observation Instrument (SOI), which collects information on the teacher and other classroom data, records information about the classroom environment and participants as in a photo "snapshot," and records the interactions and activities taking place each 5 minutes. In this report, an in-depth overview of the implementation of this model is presented. Included is information on: (1) the data collection process; (2) data analysis and interpretation; (3) teacher training processes; (4) project objectives, rationale, and history; (5) characteristics of the schools involved in the project; (6) demonstration project methods and procedures; and (7) project evaluation. Included in the appendixes are a sample observer survey, comments from project observers, and demonstration project pre/post profile summation forms. (JD)
