In this article, the author considers of what, conceptually, the evaluation design models might productively look like in the particular context of professional development (PD) in technology integration. The author describes and examines three PD programmes in New Zealand that formed the basis of the reflective review of evaluation in technology PD all had a technology focus. The author concludes that by placing participant teachers at their centre, models of PD based on action research have inherent potential to closely link both teacher effects and student outcomes directly back to aspects of the PD experience to provide a rich evidence base about those effects and outcomes from the participants’ perspective.
