### Abstract

Central to the conference theme “Research Impacting Practice”, this paper presents the findings of a large-scale mathematics professional development (PD) intervention in disadvantaged communities in Indonesia. The study investigated the impact of a lesson design-driven PD on secondary mathematics teachers’ content knowledge (CK). The cascade model was implemented in ten districts and involved 364 teachers. The PD workshops, needs analysis, scripted lesson designs and monitoring mechanisms inherent in the PD model, significantly increased teachers’ CK. The findings gathered over a period of approximately one year further our understanding of the process of large-scale PD in challenging contexts.
