previousNational Science Education Standards (NRC, 1990), The Framework and the NGSSoutline a learning progression of science and engineering practices for which studentsshould develop increasingly complex skills as they progress from early elementarythrough high school. Moreover, The Framework and the NGSS outline grade level andgrade band performance expectations related to engineering design. As a result,students are expected to engage in engineering design projects and engineering-relatedproblems in their science coursework. In an effort to address the need for high quality K12 engineering curricula, wedeveloped, implemented, and piloted the Biomedical Engineering Curriculum (BMEC, apseudonym for our program). BMEC curricula apply mathematics
