In 1988 the Ministry of Education, Western Australia implemented the 'Unit Curriculum' into Secondary High Schools throughout the state. The result of this implementation was considerable planned change to the curriculum affecting all lower school students in Western Australian government high schools. This change to the curriculum was a direct response to the 'Report of the Inquiry into the Education in Western Australia', better known as the 'Beazley Report'. This document cited a number of recommendations which were the stimuli for the aforementioned curriculum changes. However current evidence indicates that most of these desired changes dissipated in a very short period of time. The resulting impact of this ineffective curricula change is the fact that the 'Unit Curriculum' is no longer a compulsory curriculum for schools, only six years after its initial implementation. This study provides a retrospective account of the steps taken to implement this innovation. Semi- structured interviews were conducted with a group of science teachers in order to develop retrospective accounts of teachers' perceptions and reactions to the curriculum implementation process. The data from this study indicated that the innovation was implemented through power strategies. Recommendations are made which will attempt to address the problems that were produced by this curriculum innovation.
