Research commentary suggests the utilization of Tactical Games Models (TGMs) only exists in isolated instances, particularly where teachers demonstrate true fidelity to these models. In contrast, many academics have adopted TGMs into their courses. Consequently, the purpose of this study was to investigate reasons for this disparity. Participants were 44 academics and 80 physical education teachers. Results showed that academics provided a myriad of reasons why teachers may not use TGMs, although all agreed on the need for increased teacher professional development in TGMs. Physical education teachers' outlined that numerous competing versions of TGMs was confusing and they required more hands-on examples of TGMs. Results further highlighted disparities between academics and teachers' conceptual understanding and pedagogical applications of TGMs. There is a critical need to create improved connections between academics and physical education teachers, which could be achieved through the extended examination of the micropedagogies of teachers practice in TGMs.
