in this table, and (b) whether thatforce is variable and/or controllable. Completing this table clarifies several common stumblingpoints for students (such as incorrectly including pressure as a force), and ensuring that everyoneunderstands what forces to consider, and potential options to control them, when designing theROV.Hands-On Demo. In this course, students are limited to a maximum of four thrusters to use onthe ROV. The limitation on thrusters is partially financial but mostly to practice working withdesign constraints. However, it is difficult for students to understand the implication of the limitednumber of thrusters on their future ROV’s maneuverability without seeing the effects first-hand.Our students do have a lab in which

system.This bulkhead is 3D printed and can be customized based on the motors available. If desired, thisbulkhead could be expanded to separate the vessel into two watertight compartments. Within thisbulkhead, routing points are included for cables connecting the sensor package to the electronicspackage. The electronics package sits on a shelf that conforms to the curvature of the hull. Thisshelf provides a level mounting platform for the electronics while elevating them above the innersurface of the hull in case there are any leaks. For this application, the electronics package isprotected in a separate IP67 waterproof case that was on-hand.The electronics package consists of a Pixhawk flight controller, a Raspberry Pi 3 B+, and anArduino Uno.

distinct but complementary functions: (a) a contentrepository, (b) an audience response system to deliver content, and (c) learning analytics thatprovide data to instructors and researchers. It houses over 3,000 ConcepTests, which are shortquestions that can rapidly be deployed to engage students in concept-oriented thinking and/or toassess students’ conceptual knowledge, along with more extensive concept-based active learningtools and concept inventories. Screenshots of students’ views of a ConcepTest and aninstructional tool developed during this project are shown in Figures 1 and 2, respectively. TheConcept Warehouse has grown rapidly over the last five years with over 1,200 faculty accountsand 28,000 student users (Friedrichsen, Smith, and
