This chapter explores the way in which technology has been introduced through and by science educators in Australasia in the last 25 years. A number of themes have arisen in this time from using technology to engage students in science, exploring the impact of science on society through technology, considerations of the nature of technology in relation to science, and the exploration and development of technology as a subject in its own right. In this process student and teacher perceptions of technology were explored, as well as teacher change and the influence of teacher/ subject culture through to sustained classroom research and school change and the way in which the introduction of a new subject like technology can influence our thinking around science.
