Experiential learning in an undergraduate ecology course: a case study with gopher tortoise (Gopherus polyphemus Daudin)

For the purpose of assessing the value of field research for undergraduate students, Gopherus polyphemus Daudin (gopher tortoise) burrows were surveyed using a modified independent-observer sampling method by professional biologists in summer, 2015, and repeated by an Ecology class in winter, 2016, at Huguenot Memorial Park, northeastern Florida. Burrow density estimates and detection probabilities were similar for biologists and students (20.5 and 24.2 burrows per ha, mean detection probability = 0.72 and 0.75, respectively). Summer occupancy of non-collapsed burrows was 51.2% and burrow widths ranged between 6.4–40.8 cm, providing support that the population included juvenile and adult tortoises. Positive impacts in student learning were indicated from writing samples, anonymous surveys, and reflection essays. Students showed measurable gains in hypothesis development and data interpretation, and self-reported gains in understanding of ecological concepts with the integration of a field research project. Findings from this study support the value of field research as a pedagogical tool and its potential application for citizen scientist projects.
