Validity of Interval Recording in Measuring Classroom Climates in Physical Education
The purpose of this study was to determine the validity of interval recording utilizing a 5-s whole-interval observe time period and 5-s, 10-s, and 20-s lengths of recording intervals in measuring the classroom climates of management, instruction, and activity in a physical education setting. The various record-interval lengths were always in conjunction with a 5-s observe interval. Subjects in the study were 9 physical education teachers from elementary, junior high, and senior high levels. Activities taught by the subjects included rhythms, gymnastics, ball handling, badminton, tennis, and swimming. Each subject was videotaped for one lesson (M=28.9 min). The videotape bank was used to determine the actual and estimated time subjects spent in each climate. Comparison of the continuous time spent in management, instruction, and activity was made with the 5-s observe, 5-s record; 5-s observe, 10-s record; and 5-s observe, 20-s record interval techniques. Data were analyzed utilizing an ANOVA with repeated measures on the continuous factor. Results indicated no significant difference between continuous recording of management, instruction, and activity climates and any of the three observe-record methods. These results suggest that the observe-record methods were valid estimates of time spent in management, instruction, and activity climates.
