The purpose of this study is to explore what the role of a health and physical education (HPE) specialist teacher in the primary school entails. The new Australian Curriculum: HPE Framework requires schools and teachers to implement the HPE key learning area. Many self-perceived physical education (PE) teachers have voiced concern about not knowing how they go about this. This research investigates 'How PE teachers best become HPE teachers?' We are reminded by Kirk that this is not the first time teachers have implemented this very change in Australia. Many similarities can be drawn between the recent national Australian Curriculum: HPE and the 1994 HPE National Statement and Profile, which provided a foundation for the construction of the 1999 Queensland HPE (P-10) Syllabus. As recommended by Kirk this study "look[s] to the past for lessons about the present and where we might be heading in the future", by investigating school responses to the 1999 Queensland HPE (P-10) syllabus and curriculum documents. Within the constructionist paradigm, an interpretivist study was conducted. The methodology chosen to construct meanings through capturing the context of each school was "evaluative" and "multiple" case study. The sites for the three case studies involved: one small; one medium; and one large-sized Brisbane Catholic Education primary school. The three case studies were selected as representative of different demographics and the methods engaged so as to enable precision of details were semi-structured interviews, reflective journal, observations and document analysis. Data gathered suggest that enacting the HPE key learning area is very achievable. Implementation is enhanced by HPE leadership, underpinned by clear communication. More so, barriers can be overcome through professional development and support. This study is significant nationally, and the findings may be of wider international interest. It models how school leaders can optimise the health opportunities within their context and models how PE teachers can become HPE teachers.
