The document summarizes a study on engineering education in K-12 schools. It found that while K-12 engineering programs have grown, reaching about 6 million students, they remain small with limited teacher training. The study explored connections between engineering and other STEM subjects. It found positive impacts on student learning and interest in math and science, but noted a lack of diversity in programs and research on causal relationships. Recommendations included defining STEM literacy, better integrating engineering design into other subjects, collecting more impact data, and preparing teachers to lead K-12 engineering education.
