Mid-Atlantic Section Fall Conference
A design, build, and test (DBT) approach for studying the mechanical behavior of materials in an engineering materials laboratory is shown to create a flexible learning environment which imparts thinking competencies. Traditionally, students have utilized conventional testers such as a universal testing machine for studying the stress-strain relationship and for measuring properties such as the modulus of elasticity and shear modulus. In the DBT approach, the student teams designed and built single-task devices and tested them for measuring specific mechanical properties. The surveys affirmed that student engagement, self-reliance, problem solving, and teamwork which are attributes of the project-based learning (PBL) method were improved. Additionally, innovative thinking in face of cost constraints and gaining manufacturing and assembly skills were enhanced because of the design and build activates. As the student teams advanced through the projects in the laboratory, the accuracy of measured properties compared with the nominal values notably increased.
