Curriculum integration and working in teams are two key characteristics of middle schooling in Australia today. As part of a new primary/middle teacher education program an interdisciplinary team of academics has developed a course that aims to teach pre service teachers how to plan for and teach an integrated curriculum unit in an authentic context: their 6 week school placement. This paper will describe the first cycle of an action research project detailing the issues for the third year pre service teachers and for the staff involved in teaching the course as they come to grips with new ways of working. This is an action research project and the data includes course materials, staff notes and journals and student assignments. A number of key issues have emerged from this trial including pre services teachers' knowledge of how curriculum is constructed at this stage of their career and the difficulties of modeling this approach.
