The purpose of this study was to collect data on behavior, including educational media usage, in a wide range of educational settings through use of participant observation. Eight special education teachers and their classrooms were used. An instrument adapted from the OSTRAQ system was used to measure 12 categories of pupil-teacher interaction including media resources usage. The results of the study suggest contrasting patterns of teacher-pupil interaction. The discussion of findings includes descriptions of classroom conditions, instructional situations, and analysis of effectiveness of the instrument and of participant observation as a data-gathering technique for this type of study.
