Brett Austin McCandless is a graduate student at North Carolina State University, where he is pursuing a Ph.D. in Mechanical Engineering. He is also a course instructor at North Carolina State University, Campbell University, and Johnston Community College. He is currently researching ultrasound propagation in bone, in the hopes that understanding the propagation will lead to better pre-screening methods for osteoporosis.
The author is a Teaching Associate Professor at North Carolina State University in the Mechanical and Aerospace Engineering Department. She teaches undergraduate courses in the thermal-fluid sciences. She is the course coordinator for Thermodynamics I and has taught the course in the traditional lecture and flipped formats.
Education quality improves when students are able to apply their knowledge to real-world examples, particularly when students are able to move beyond just working through textbook problems and lecture notes. When working through conceptual design projects, this may be accomplished fairly easily in small class sections, for there are fewer practical limitations to evaluating all students’ different design outcomes. However, this becomes problematic in larger class sections, for there are frequently limitations on the amount of instructor time and instructional support for grading open-ended design work.
To address these issues, a thermodynamics project was developed which put students into teams to design a pump system. Students were put into groups and told they were in charge of an oil company. The company was charged with designing a pump system to pump oil from an endless underground reservoir to the surface of the earth. Students were given a series of different pumps and types of piping to use for their design. Students used a first-law based analysis to ideate this designs. Students also had options to operate their system during different time blocks and to add filtration to their oil. Financially, students would make back their money by selling oil. Students also addressed social considerations of their designs via a “social score.”
Students submitted their projects in two parts. Groups first submitted a preliminary design, along with various calculations necessary to complete the design. Groups inputted their design parameters and answers into a Google form, where coding was done to automatically check and grade students’ design parameters and corresponding calculations. Students were then permitted to optimize their design and resubmit their work, where they were competitively awarded points based on the financial and social metrics of their designs.
