Engaging Undergraduate Biomedical Engineering Students in Lab on a Chip Research through a Course-Based ProjectRecently, there has been significant interest in enhancing the research skills of undergraduatebiomedical engineering (BME) students, since such abilities are critical for graduate studies andcareers in research and development . However, there are limited opportunities for research inmany undergraduate BME programs, and many of these experiences are extracurricular in natureor are only available to a small percentage of students . On the other hand, research projectsthat are integrated within courses offer opportunities for skill development to a larger number ofundergraduate students. Moreover, authentic learning experiences (i.e., projects pertaining toactive faculty research areas as opposed to academic exercises) have been shown to enhancestudent learning and retention . In this work, a course-based project was developed andimplemented to engage undergraduate BME students in Lab on a Chip (LOC) research.The research project was integrated within XXX – Lab on a Chip, which introduces students tothe theory and application of microfluidic systems to medicine and biology. In the originalcourse format, a standard lecture and laboratory approach was utilized. In the new format, aresearch project was implemented that formed the basis for all learning in the course. Theproject, which was introduced on the first day of the course, involved the development of a LOCdevice to measure hematocrit in a blood sample. Once the project had been described to thestudents, all subsequent lectures were designed to deliver content required for each stage of thedevice development process, including concept generation, design, fabrication, and testing. Atthe end of the course, the final fabricated device for each group was tested with bovine wholeblood to determine its performance in measuring hematocrit.In order to assess the impact of the new format on student interest and attitudes toward the LOCresearch field, a set of pre- and post-course surveys were developed and administered. Thesurveys used 5-choice Likert questions, which were analyzed using a one-tailed, paired t-testwith a significance level of 0.05. The results from the surveys (Fig. 1) showed increased student-reported knowledge regarding LOC technologies (p=6.05x10-5), confidence in their ability todevelop LOC devices (p=1.21x10-4), level of interest in pursuing further studies/training in thearea of LOC (p=0.048), and likelihood in pursuing a career in the area of LOC (p=0.004).Due to the success of the new course format, which was implemented for the first time in Spring2012, it is expected that subsequent offerings will maintain the course-based research projectapproach. Furthermore, the design concepts that showed the greatest promise during thepreliminary testing conducted during the course-based project have been selected to moveforward in the research program of the course instructor. Thus, the course-based approach toundergraduate research provided benefit to both the students and the faculty at our institution.References P. Schuster and C.
