Leveraging remote learning during the Covid-19 pandemic to enhance student understanding of biodiversity

Abstract

We evaluated whether individual nature-based ecological (NBE) study used in tandem with group collaboration enhanced undergraduate student understanding of ecological concepts and pro-environmental perceptions. In response to the Covid-19 pandemic, we developed a multiweek unit on the latitude diversity gradient (LDG) for fully online instruction that leveraged the unique situation of students learning in disparate geographic locations. Student understanding of the LDG and pro-environmental perceptions were assessed with surveys administered both pre- and post-activity in an introductory-level biology laboratory course. Student understanding of the geographic location where biodiversity is the highest was high prior to the start of the laboratory unit and exhibited only a small improvement after the unit. In contrast, students’ higher order thinking around the LDG was enhanced by the lab activity. Student environmental perceptions shifted toward ecocentric views and away from anthropocentric views after the laboratory unit. The greatest gains in ecological understanding and shifts toward ecocentric viewpoints occurred in the group of students who visited their field sites most often. Our results provide further evidence as to the value of NBE for the introductory biology laboratory, even in an online learning setting. The lab unit described in this study provides a potential approach to teaching ecology in an online format that could easily be adapted to fit the needs of a particular curriculum.
