If the movement toward more project-based learning is to be successful, it's essential to understand what teachers need to do to be effective in a project-based classroom. Pam Grossman, Christopher G. Pupik Dean, Sarah Schneider Kavanagh, and Zachary Herrmann surveyed experts and teachers and viewed classroom videos to identify a set of core practices for project-based teaching. Effective project-based educators promote subject-area learning; create relevant experiences; cultivate a classroom culture of production, feedback, reflection, and revision; and build student agency in learning communities.
