The purpose of this study was to investigate whether interval and time sampling methods of measuring student engaged time are valid for estimating the actual time students spend engaged in relevant motor performance in physical education classes. Two versions of the interval Academic Learning Time in Physical Education (ALT-PE) instrument and an equivalent time sampling method were compared with actual time students spent in motor performance. Thirty-six students enrolled in six different university physical education classes were the subjects. The actual student engaged time and engaged time as estimated by the time sampling instrument were significantly lower than the time as estimated with the two ALT-PE instruments. In addition, a class type by coding instrument interaction occurred indicating that the difference was present for all classes except where activity is continuous. This result suggests that the popularity of the ALT-PE instruments should be reexamined.
