"This thesis explores how the impacts of Australian media assistance on social change and governance can be most effectively evaluated and understood. It is based on a three-stage research design, using predominantly qualitative research methods. In doing so it contributes in-depth insights into the politics, theories, and practices of media assistance evaluation, with illustrations of how this knowledge can be directly applied to improve practice in this area. The findings of this research suggest the importance of early investment in participatory planning of evaluation designs, which are then periodically revisited. These evaluation designs should be based on a theoretically sound link between models of change, evaluative questions and methods." (Abstract)
