An increased focus on educational transformation in STEM disciplines has led to a burgeoning field of materials education research. This book details the Symposium PP, Materials Education - detailing the inspirational story of Marni Goldman - a pioneer in the field, who promoted excellence and accessibility in materials research education, while also promoting educational opportunities for the disabled - motivated the unique focus of this symposium: accessible education at all levels, 'K through Grey'. The work spans traditional materials education research in higher education; SoTL work in K-12 schools, higher education, museums and outreach organizations; accessibility research for learners and professionals with disabilities (ranging from acute physical to 'hidden' mental); and materials education and outreach programs of Materials Research Science and Engineering Centers (MRSECs), Nanoscale Science and Engineering Centers (NSECs) and the Nanoscale Informal Science Education Network (NISE Net).
