This paper reports the findings of an exploratory study concerning the development of higher-order conceptual understanding of Teaching Games for Understanding (TGfU) among physical education pre-service teachers. The development of such understandings has been seen as problematic among pre-service teachers (Randall, 2003). An analysis of the responses given in a high- stakes examination of 165 pre-service physical education teachers was used to investigate varying levels of understanding in TGfU pedagogy. This paper reports specific examples of student responses in a written high-stakes examination and justifies how a two-cycle structure of the observed learning outcome (SOLO) model can discriminate between the demonstrations of surface and deep conceptual understandings.
