This paper explores enabling conditions for scaling high-quality project-based learning (PBL) to understand factors that influence how PBL spreads, whether and how it can be sustained and the extent to which it informs meaningful change in schools. We report on a year-long collaboration across three research projects. Each project team analyzed…

Because of the extremely short time frame of the class, students would be inundated with an overwhelming number of new concepts and definitions. Hence, we employed concept mapping to increase student retention and…
