Teachers who do not integrate technology are often labelled as 'resistant' to change. Yet, considerable uncertainties remain about appropriate uses and actual value of technology in teaching and learning, which can make integration and change seem risky. The purpose of this article is to explore the nature of teachers' analytical and affective risk perceptions, and how these influence decisions to integrate technology in their teaching practice. These ideas are explored through an in-depth qualitative analysis of teacher interviews focusing on experiences with, and beliefs about, technology and teaching. Results suggest decisions to integrate technology in teaching are influenced by negative affective responses to technology, general risk-aversion in teaching, and the perceived value of technology in teaching. The risk analysis framework and findings presented in this paper can be used to support communication with teachers to minimise perceived risks and, where appropriate, help support future technology use.
