Contents ALT-PE Versions I and II: Evolution of a Student-Centered Observation System in Physical Education
Although many observation instruments have been developed in physical education, few have enjoyed such widespread use in such a short time as the Academic Learning Time in Physical Education (ALT-PE) model. Not only has this observation system been used in a variety of research settings, but it has undergone an evolution in concept and coding categories. What does this do to the conceptual underpinnings of this observation system? Will the newer version yield similar or different kinds of information? This article attempts to answer such questions by comparing the two versions on the same set of videotaped physical education classes. Results demonstrate that versions I and II both provide similar information about students’ opportunities to learn physical education skills, yet each system has some advantages over the other. Either version can be a useful and appropriate research tool depending on the research question(s) being asked.
