Establishing A Content Taxonomy For The Coherent Study Of Engineering In P-12 Schools, Greg Strimel, Tanner Huffman, Michael Grubbs, Eunhye Kim, Jamie Gurganus

Journal of Pre-College Engineering Education Research (J-PEER)

Engineering education has increasingly become an area of interest at the P-12 level, yet attempts to align engineering knowledge, skills, and habits to existing elementary and secondary educational programming have been parochial in nature (e.g., for a specific context, grade, or initiative). Consequently, a need exists to establish a coherent P-12 content framework for engineering teaching and learning, which would serve as both an epistemological foundation for the subject and a guide for the design of developmentally appropriate educational standards, performance expectations, learning progressions, and assessments. A comprehensive framework for P-12 engineering education would include a compelling rationale and ...
