This report describes classroom observation techniques used to record the behavior of educational specialists (teachers) and students in a kindergarten and a first grade classroom of the Kamehameha Early Education Program (KEEP). Classroom behavior was observed and recorded daily during the 1973-1974 school year. Each student was observed three times during each of three daily observation sessions. Behavior during these observation sessions was designated as on-task, off-task, or disruptive. Three coding systems were used successively during the year for recording teacher behavior. Difficulties encountered in the first coding system led to the modifications used in systems II and III. Each of these coding systems focused on the teacher's reinforcement of student behavior. The reliability of the teacher and student coding systems was analyzed by comparing the coding records of independent observers. (BD)
