This is the second of two articles about the National Science Foundation-funded Engineering for All (EfA) program which focuses on engineering as a potential social good, revisits major Technology and Engineering (T&E) themes (design, modeling, systems, resources, and human values) in two authentic social contexts (Food and Water), and uses informed design pedagogy. This article focuses on EfA classroom implementation. The contributing authors are teachers who have served in leadership roles during the development and classroom testing of the program.
