Julie Leonard-Duke is a current graduate student in Biomedical Engineering at UVA highly interested in engineering education research. During her undergraduate degree at Georgia Tech, Julie was involved with engineering education research in the Department of Biomedical Engineering and the Center for Academic Success. Additionally, Julie was named a University Innovation Fellow and through her training at the Stanford Design School designed a new undergraduate Biomedical Engineering course at Georgia Tech that was formally added to the curriculum in the Fall of 2019. Julie's research at UVA has focused on encouraging students to integrate technology with their learning.

Dr. Timothy E. Allen is a Professor in the Department of Biomedical Engineering at the University of Virginia. He received a B.S.E. in Biomedical Engineering at Duke University and M.S. and Ph.D. degrees in Bioengineering at the University of California, San Diego. Dr. Allen's teaching activities include coordinating the undergraduate teaching labs and co-teaching the Capstone Design sequence in the BME department at the University of Virginia, and his research interests are in the fields of computational biology and bioinformatics. He is also interested in evaluating the pedagogical approaches optimal for teaching lab concepts and skills, computational modeling approaches, and professionalism within design classes. He is active within the Biomedical Engineering Division of the American Society for Engineering Education and previously served on the executive committee of this division (Program Chair 2011, Division Chair 2012, and Nominating Committee Chair 2013). Dr. Allen is the recipient of ten teaching awards at UVA, including the All-University Teaching Award in 2017. Since 2016, he has been the PI on an NSF REU site focused on multi-scale systems bioengineering and biomedical data sciences, a collaboration involving faculty in SEAS, SOM, SDS, and CLAS at UVA, as well as six partner institutions in the mid-Atlantic and Southeast.
Pre-recorded presentations are becoming more prevalent in professional settings, such as conferences and in the classroom, and require a different but related skill-set than the standard in-person presentation. To evaluate student performance and understanding of pre-recorded versus in-person presentations we conducted a preliminary research study in a Systems Bioengineering course with a mixture of undergraduate and graduate enrollment. For each of the four course modules, students were randomly assigned groups with at least two graduate students per group and developed a small computational model based on the module’s topic. Students presented their work in a pre-recorded presentation in the first and third modules and in an in-person presentation in the second and fourth modules. At the end of the course, students were asked to complete an anonymous Qualtrics survey, developed based on previous surveys that evaluated in-person versus virtual presentation formats[1, 2], to identify the positives and negatives associated with pre-recorded presentation on both the presenter and the audience member. Nine students, eight graduate students, and one undergraduate student completed the survey. All students had prior experience with in-person presentations, but only two students had previous experience with pre-recorded presentations. Students rated how delivering presentations in each presentation style impacted a variety of learning outcomes, such as ability to be innovative and take risks, improving teamwork skills, and improving communication skills, on a scale of 1 to 10—with 1 being no impact and 10 being great impact. In general, across all categories delivering in-person presentations were rated higher than delivering pre-recorded presentations, with an average mean score of 7.91±1.92 versus 4.24±2.94. Similar trends were seen in the results for audience learning for in-person versus pre-recorded presentations. Learning objectives assessed for being an audience member during each presentation style included understanding of the project presented, ability to think critically about the project, willingness to ask questions, and understanding of the overall module. Across all audience learning categories, in-person presentation scores averaged 7.5±1.66 while pre-recorded presentations again scored lower, but with large standard deviations, at 3.83±3.16. Students were also asked two short answer questions on which presentation medium they would pick in the future and challenges they faced when making the different types of presentations. While the majority of students indicated a preference for in-person presentations, two students preferred pre-recorded presentations, stating that pre-recorded presentations “[L]ets you be sure to articulate clearly with multiple attempts” and “Although it took more time and was harder to gather everyone for the pre-recorded presentations let me think about the other groups presenting instead of going over information I would have to present when it was my groups turn.” Future work should repeat this study and further evaluate the effect of providing resources on effective ways to give pre-recorded presentations on student’s learning outcomes.
