NSF has posted a new Dear Colleague Letter (DCL): Supporting Knowledge Mobilization for PreK-12 and Informal STEM Learning and Teaching. The DCL "encourages submissions to programs within the Directorate for STEM Education’s (EDU) Division of Research on Learning in Informal and Formal Settings (DRL) for new proposals (research and other proposal types described in Chapter II.F of the NSF Proposal & Award Policies & Procedures Guide (PAPPG) such as planning, conference, etc.) addressing grand challenges of knowledge mobilization within and across domains, levels of analyses, and across research and education contexts. This DCL also calls for supplemental funding requests from current awardees to engage practitioners and education leaders as partners in the development and deployment of innovative strategies and approaches for disseminating and applying education research findings, including in under-resourced urban and rural learning spaces and communities."
