A low-cost cure for CUREs: An undergraduate microbiology course engaging students in authentic research using publicly available datasets.

Undergraduate research experiences are key to preparing STEM students for a range of careers and graduate programs, and to impacting retention in STEM. Providing undergraduate research experiences can be challenging for institutions due to the high cost associated with equipment and reagents, lab space, and research mentors. In this study, we present an upper-level microbiology seminar course that does not require these resources, as each student chooses and performs their own research project using data obtained from publicly available datasets. The faculty member provides hands-on instruction and regular feedback to mentor the cohort of students through all stages of their research projects, from honing a research question, to choosing a dataset, to data analysis and visualization. Students build science communication skills through each writing a scientific paper, and creating and presenting a scientific poster. These papers and presentations, along with results from student pre- and post-surveys, demonstrate that students built research and communication skills, while also building their confidence and interest in science careers. To access this research experience, students only need to register for this course; no application or selection is required, and no prior research experience is expected. The use of publicly available data makes this course a low-cost way to integrate authentic research projects into the college curriculum, and can be adapted to courses in any discipline. Such "low-cost CUREs" (course-based undergraduate research experiences) can be used to build capacity for undergraduate research experiences that are so crucial to preparing students for opportunities in and beyond college.
