The purpose of this study was to observe and describe the teaching behavior and interaction patterns of four elementary school physical education teachers longitudinally. Each teacher was observed twice a day (AM and PM) for a period of 20 consecutive days, resulting in 40 observations per subject. The following conclusions were reached: (1) teaching behavior and interaction patterns vary minimally over 20 days; (2) traditional, nonhumanistic teaching styles prevailed in the movement classes observed; (3) variable of time of day, grade level, and day of the week have a negligible influence on teaching behavior and interaction in physical education classes; (4) significant differences exist in teaching behavior between male and female teachers; and (5) content of the lesson was found to be an influential factor on interaction and teaching behavior in the gymnasium.
