Course Title:  Engineering Design and Development (EDD)

 

Course Description:  This capstone course enables students to apply what they have learned in academic and pre-engineering courses as they complete challenging, self-directed projects.  Students work in teams to design and build solutions to authentic engineering problems. An engineer from the school’s partnership team mentors each student team.  Students keep journals of notes, sketches, mathematical calculations and scientific research.  Student teams make progress reports to their peers, mentor and instructor and exchange constructive criticism and consultation.  At the end of the course, teams present their research paper and defend their projects to a panel of engineers, business leaders and engineering college educators for professional review and feedback.  This course equips students with the independent study skills that they will need in postsecondary education and careers in engineering and engineering technology.

 

From launching space explorations to delivering safe, clean water to communities, engineers find solutions to pressing problems and turn their ideas into reality. PLTW Engineering empowers students to step into the role of an engineer, adopt a problem-solving mindset, and make the leap from dreamers to doers. Each PLTW Engineering course engages students in interdisciplinary activities like working with a client to design a home, programming electronic devices or robotic arms, or exploring algae as a biofuel source. These activities not only build knowledge and skills in engineering, but also empower students to develop essential skills such as problem solving, critical and creative thinking, communication, collaboration, and perseverance.
