Old Dominion University and Norfolk State University, in collaboration with the marine industry and local school systems, is improving STEM preparation using innovative experiences for students and teachers in the nation's major shipbuilding and repair areas through MarineTech and SBRCD (Shipbuilding Repair and Maritime Career Day) projects. The MarineTech project will be serving 60 students in grades eight through twelve over a period of three years by providing 144 hours of instruction and hands-on learning experiences in the fields of marine engineering and physical sciences, with a shipbuilding focus. MarineTech's progressive curriculum covers foundational skills and knowledge of basic physical science as it relates to shipbuilding through the application of these principles in a culminating ship-design competition. The curriculum is enriched with program activities such as field trips to shipbuilding and repair companies, marine science museums, and career-day events. The MarineTech project has successfully developed and integrated Project-Based Learning activities within the middle and high school curriculum. The Marine Kit activities and the Instructional Modules complement the Standards of Learning for middle and high schools. This article discusses the design and development of these activities and its subsequent implementation within the classroom. (Contains 6 figures.)
