The manual, designed particularly for work with acting-out or behavior problem students, describes coding procedures used in the observation of continuous classroom interactions between the student and his peers and teacher. Peer and/or teacher behaviors antecedent and consequent to the subject's behavior are identified in the coding process, establishing a sequential behavioral pattern. Detailed are standardized procedures for observer interactions with academic personnel, timing within observations, and reliability checks. How to fill in the coding sheet is outlined and definitions are provided for the abbreviations used in recording source of the behavior, direction of the behavior, and type of behavior. Behaviors defined include those found fairly frequently in acting-out students. Specific rules are given for who, when, and how to code, and a sample protocol is provided. Appendixes include questions and answers concerning identification, procedural, and definitional coding problems. (KW)
