With the release of the Technology Years 1 to 10 Syllabus and associated curriculum materials by the Queensland Studies Authority in 2003, Education Queensland announced that all Queensland government schools were to aim for full implementation by 2007. This paper reports the findings of an investigation into the intrinsic and extrinsic challenges experienced by teachers during the implementation of Technology Education. Student and teacher interviews, observations, artefact collection using digital photographs, and the administration of the Technology Syllabus Implementation Questionnaire (TSIQ) were undertaken to develop case studies. The major findings of this study included the identification of intrinsic challenges being professional knowledge and understanding, teacher confidence in the teaching of technology, attitudes and values of the Technology key learning area, and approaches to teaching. Extrinsic challenges included a lack of resources and time, varying methods of student assessment, the practicality of the implementation of a new curriculum area, and the quality of professional development programs. From the challenges identified, suggestions are made to inform the future implementation of Technology Education.
