AUTHENTIC UNDERGRADUATE RESEARCH EXPERIENCES IN GENERAL BIOLOGY LABS INSPIRED BY FRESHWATER ECOLOGY AND AQUATIC ENTOMOLOGY

The over-emphasis on memorization of content (definitions, concepts, names) in introductory science courses, combined with a weeding-out, deficit-mentality philosophy of teaching, has pushed generations of students away from undergraduate majors and careers in the sciences. Course-based undergraduate research experiences are designed to engage students in the excitement of science, emphasize an understanding of core concepts and scientific competencies, and encourage students as contributing members of the scientific community. We used research questions and approaches from freshwater ecology and aquatic entomology to design multi-week authentic research experiences for a second-semester general biology laboratory course. Students used stream benthic macroinvertebrates to explore community ecology and ecological data analysis in one 3-week module. Another module introduced students to morphological and molecular phylogenetics and landscape genetics using DNA barcoding of target aquatic insect taxa, and asked students to interpret inter- and intra-species phylogenies based on evolutionary processes. The course culminated in students sharing their own independent research study in a poster session. Overall, students had increased enthusiasm and engagement in the process of science in the redesigned course compared to a traditional laboratory course.
