The design, build and test (DBT) project was created with the idea that the best way to learn engineering is by doing engineering. The primary goal of a DBTproject is to provide students with an experience that is fun, motivating and educational. In addition, a DBT project is designed to be easy to implement. The preeminent feature of a DBT project is the extensive use of science, math, and calculations to guide design efforts prior to construction. Key factors in designing an effective DBT project are (1) selecting an appealing topic that is amenable to simple prototype construction, (2) using metrics to define the project goal, (3) instituting a mentoring culture, (4) involving substantial mathematical modeling, (5) guiding students using iteration cycles, (6) motivating students by using competition and public presentation, and (7) continuously improving a project by collecting project resources.
