In partnership with the XQ Super School Project, we provide coaching and design support for interdisciplinary project-based learning (PBL) for a growing cohort drawn from the Super School network. Selected teachers spend a week at MIT during the summer learning about interdisciplinary PBL by designing a project alongside MIT staff and researchers, while also participating in sessions and demonstration lessons that help teachers to explore and practice a variety of inquiry-based and culturally-relevant approaches that foster active and authentic student engagement. We framed our project work in terms of the XQ Learner Goals, which aim to map the holistic academic and social skills most relevant for success in the contemporary global economy. In addition to in-person meetings, our ongoing virtual coaching involves co-designing with teachers to personalize instruction for students by reflecting on several developmental bands that correlate to the Learner Goals.
