e4usa provides a standardized educational curriculum for pre-college students to learn and demonstrate engineering principles, skills and practices. The curriculum incorporates an authentic, design-based experience and affords students the opportunity to earn college credit at participating colleges and universities. The course, Engineering for US All (e4usa), empowers, engages, and excites students to use what they know and find what they are passionate about to take control and boldly influence the world. Empowerment is built through an awareness of engineering in everyday life, the diversity of engineers, and by interrogating and emphasizing how engineering is embedded in society. Engagement occurs as students practice engineering design at multiple scales, considering local and global engineering design challenges. e4usa generates excitement as students are provided opportunities to design and create solutions in authentic, student-centered product development challenges. e4usa invites all schools, teachers, and students to fully participate regardless of their technical background or preparation. The mission of engineering for US All (e4usa) encompasses both students and teachers. Paramount to the success of e4usa is the construction and delivery of professional learning (PL) experiences to prepare and support teachers with different levels of engineering training instruction as they implement the course. Teachers are introduced to the curriculum and inclusive classroom practices through a structured Summer PD and year-round PL that involve hands-on teaching and learning experiences that enhance teachers’ confidence and requisite skills to teach engineering design.
