Research Design & Methodology

This study entails a mixed methods approach using interviews, observations and previously collected metric data. Previous studies of scale in policy, international development and education have used predominantly qualitative methods to examine how scale is achieved (Coburn, 2003; Elmore, 1996; Samoff, Sebante & Dembele, 2003). This study design draws on the most valid and systemic approaches to studying scale emphasizing interviews and observations that help understand the key underlying mechanisms around motivation, ownership, norms and sustainability (Dede, 2006).
