The Federal STEM Education Strategic plan recognizes the importance of building computational literacy today. This document is aligned to the Computational Literacy Interagency Working Group (IWGCL) objectives to: (1) develop a common operational definition; (2) identify existing research on computational literacy; and (3) identify existing research-based model programs, content and curriculum, best practices and other measurable quantities that inform successful examples of building computational literacy in STEM education in both federal and non-federally sponsored research and programs. The intended audience of this report is federal agencies and other STEM education stakeholders, to support the understanding and implementation of computational literacy in STEM education.
