This article reports on the up-date and development of an on-line resource to support of teachers' conceptual understandings and pedagogical practice in New Zealand. Techlink is a website dedicated to supporting technology teachers, students and those with an interest in technology education. This research documents part of a Ministry of Education initiative to develop materials to support teaching and learning in technology education. The research was conducted by educational researchers contracted through Technology Education New Zealand the professional subject association. This research was a component of a larger contract with an overall aim of improving student achievement particularly at Years 12 and 13, the final 2 years of schooling in New Zealand. The aims of the initiative reported in this article were to provide ongoing evaluation of the effectiveness of the materials developed by the writing team, to support teacher shifts in understanding and pedagogical practice. This article gives an overview of the 3 year research study, focussing on teachers and teacher educators perceptions of Techlink as a professional development resource. An iterative process was used to critique and give feedback on existing and developed materials. The article also discusses enhancements made to ensure that the resource reflected the needs of technology teachers and The New Zealand Curriculum (Ministry of Education 2007).
