The development of tools that promote active learning in engineering disciplines is critical. It is widely understood that students engaged in active learning environments outperform those taught using passive methods. Previously, we reported on the development and implementation of hands-on Low-Cost Desktop Learning Modules (LCDLMs) that replicate real-world industrial equipment which serves to create active learning environments. Thus far, a miniaturized venturi meter, hydraulic loss, and double pipe and shell & tube heat exchanger DLMs have been utilized by hundreds of students across the country. It was demonstrated that the use of DLMs in face-to-face classrooms results in statistically significant improvements in student performance as well as increases in student motivation compared to students taught in a traditional lecture-only style classroom. Last year, participants in the project conducted 36 implementations including 228 DLMs at 17 universities across the country reaching 726 students.
In this work, we report on the significant progress made in broad dissemination of DLMs and accompanying pedagogy. We demonstrate that DLMs serve to increase student learning gains not only in face-to-face environments but also in virtual learning environments. Instructional videos were developed to aid in DLM-based learning during the COVID-19 pandemic when instructors were limited to virtual instruction. Preliminary results from this work show that students working with DLMs even in a virtual setting significantly outperform those taught without DLM-associated materials. Significant progress has also been made on the development of a new DLM cartridge: a see-through 3D-printed miniature fluidized bed. The new 3D printing methodology will allow for rapid prototyping and streamlined development of DLMs. A 3D-printed evaporative cooling tower DLM will also be developed in the coming year.
In October 2020, the team held a virtual implementors workshop to train new participating faculty in DLM use and implementation. In total, 13 new faculty participants from 10 universities attended the 6-hour, 2-day workshop and plan to implement DLMs in their classrooms during this academic year. In the last year, this project was disseminated in 7 presentations at the ASEE Virtual Conference (June 2020) and American Institute of Chemical Engineers Annual Conference (November 2019) as well as the AIChE virtual Community of Practice Labs Group, ultimately disseminating DLM pedagogy to approximately 200 individuals including approximately 113 university faculty. Further, the former group postdoc has accepted an instructor position at University of Wisconsin Madison where she will teach unit operations among other subjects; she and the remainder of the team believe the LCDLM project has prepared her well for that position.
In the remaining 3 years of the project, we will continue to evaluate the effectiveness of DLMs in teaching key heat transfer and fluid dynamics concepts thru implementations in the rapidly expanding pool of participating universities. Further, we continue our ongoing efforts in creating the robust support structure necessary for large-scale adoption of hands-on educational tools for promotion of hands-on interactive student learning.
