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…

Conceptual change theories assume that knowledge structures grow during the learning process but also get reorganized. Yet, this reorganization process itself is hard to examine. By using concept maps, we examined the changes in students' knowledge structures and linked it to conceptual change theory. In a longitudinal study, thirty high-achieving…
