The introduction of technology education in primary and secondary schools during the past 10-15 years around the world has presented a number of difficulties for teachers, primarily related to their coming to understand the phenomenon of technology and to conceptualise the technology learning area in line with national frameworks. This paper reports on a professional development experience that aimed to assist a small group of primary school teachers to develop their understandings of technology and technology education. A theoretical model framed a series of professional development interactions between the researchers and the experienced teachers who were new to teaching technology. Data sources included teacher interviews, video recordings of the activities, teacher made models, and extracts from their reflective journals. The study presented some insights into how professional development experiences for teachers new to technology could be organised and implemented to best support their developing technology practices and understandings.
