Nine scales were developed to measure a series of classroom behavior variables derived from a factor analytic study of five observation systems. The scales are multipoint check lists which are behaviorally referenced by different amounts and types of classroom behaviors. The scales measure such aspects of classroom behavior as teacher-initiated problem solving, negative and positive affect, and pupil-to-pupil interaction. Data are given for between-observer agreement and for stability. The scales may be useful for helping preservice teachers to observe a number of aspects of classroom behavior and for assessment and feedback in teacher training programs. (Author)
