Xianglong Wang is an Assistant Professor of Teaching at University of California, Davis. He is interested in problem-based learning in bioinstrumentation courses, gender equity in teaching of machine learning, and student experience and retention in BME students. He won the Teaching Excellence award in Biomedical Engineering at UC Davis in 2023. Prior to joining UC Davis, Xianglong was an Assistant Professor (Teaching) at Washington State University during 2020-2022, winning the Reid Miller Teaching Excellence Award in 2022.
David Lin is an Associate Professor with a joint appointment in the Voiland School of Chemical Engineering and Bioengineering and Department of Integrative Physiology and Neuroscience at Washington State University, Pullman, WA. His teaching interests are in Bioinstrumentation, Biomechanics, Control Systems, and Physiology. His research interests are in the Biomechanics of the musculosketal systems and multi-scale physiology of muscle contraction.
The COVID pandemic has introduced lower levels of attendance and engagement in the student. Our observations indicated that these levels did not fully return after transitioning back to in-person instruction. Integrating design thinking and problem-based learning (PBL) into the curriculum is thought to benefit engagement and motivation. In this study across two campuses, the authors propose to integrate themed PBL into the lecture portion of the bioinstrumentation course, which is a required course in more than 90% of the biomedical engineering or bioengineering programs. The new lectures were designed to fit into various levels of existing lab protocols. A theme of rediscovering the design of an electromyography (EMG)-based bedside controller was used throughout the course. The bioinstrumentation course contains modules of measurement principles, sensors, interfacing, filtering, and digitization. These modules are essential for modern electronics measurement systems and were the major components of the EMG controller. At the end of each module, students were asked to design the corresponding functions of the EMG controller. Students created a full design for the signal acquisition and conditioning parts of the EMG controller at the end of the course. Through our two trial runs, we have found that the students' satisfaction about the bioinstrumentation course has increased. Students' performance has increased during our trial run at [site 1], and data analysis will be taking place in [site 2] following proper IRB approval. We plan to further investigate whether the themed PBL affects students' performance compared to circuits (prerequisite of bioinstrumentation), in addition to students' motivation and interest levels in bioinstrumentation.
