This article, which originally appeared in the Journal of Engineering Education, reports on an experimental study of the use of a peer rating system in an introductory engineering course. The study examines the incidence of students receiving low ratings from all their teammates, inflated and...

This 22-page report, published by Pensacola Catholic High School, describes the design and construction of the underwater remotely operated vehicle (ROV) created by the Achelous team for the Ranger Class of the 2023 MATE ROV competition. MATE ROV is a global competition that challenges STEM students...

This 39-page report is written by Eric Wooldridge, who demonstrates that adopting desktop additive manufacturing (AM) processes can be low cost and improve efficiency. In this study, Wooldridge evaluates the cost-savings potential of using 3D printers to produce tools, equipment, and spare parts...

This 16-page paper, provided by Southeast Maritime and Transportation (SMART) Center, includes the findings from a two-day focus group of Port of Baltimore area employers, workforce intermediaries, and educators. This focus group addressed emerging port and maritime industry workforce gaps. The ...

This video, provided by Columbia Gorge Community College, is the first part of a two part lecture that discusses "adjusting acceleration and deceleration times and profiles on the Omron 3G3JX-AE004 motor drive." The lecture also covers recovering the "motor drive from an overvoltage event during...
