  We present the Classroom Technology Deployment Matrix (CTDM), a tool for
high-level Planning, Monitoring, Evaluating and Reporting of classroom
deployments of educational technologies, enabling researchers, teachers and
schools to work together for successful deployments. The tool is de-rived from
a review of literature on technology adaptation (at the individual, process and
organisation level), concluding that Normalization Process Theory, which seeks
to explain the social processes that lead to the routine embedding of
innovative technology in an existing system, would a suitable foundation for
developing this matrix. This can be leveraged in the specific context of the
classroom, specifically including the Normal Desired State of teachers. We
explore this classroom context, and the developed CTDM, through look-ing at two
separate deployments (different schools and teachers) of the same technology
(Collocated Collaborative Writing), observing how lessons learned from the
first changed our approach to the second. The descriptive and an-alytical value
of the tool is then demonstrated through map-ping these observation to the
matrix and can be applied to future deployments.
