Teaching R in the undergraduate ecology classroom: approaches, lessons learned, and recommendations

Abstract

<jats:title>Abstract</jats:title><jats:p>Ecology requires training in data management and analysis. In this paper, we present data from the last 10 years demonstrating the increase in the use of R, an open-source programming environment, in ecology and its prevalence as a required skill in job descriptions. Because of its transparent and flexible nature, R is increasingly used for data management and analysis in the field of ecology. Consequently, job postings targeting candidates with a bachelor’s degree and a required knowledge of R have increased over the past ten years. We discuss our experiences teaching undergraduates R in two advanced ecology classes using different approaches. One approach, in a course with a field lab, focused on collecting, cleaning, and preparing data for analysis. The other approach, in a course without a field lab, focused on analyzing existing data sets and applying the results to content discussed in the lecture portion of the course. Our experiences determined that each approach had strengths and weaknesses. We recommend that above all, instructors of ecology and related subjects should be encouraged to include R in their coursework. Furthermore, instructors should be aware of the following: learning R is a separate skill from learning statistics; writing R assignments is a significant time sink for course preparation; and, there is a tradeoff between teaching R and teaching content. Determining how one’s course fits into the curriculum and identifying resources outside of the classroom for students’ continued practice will ensure that R training is successful and will extend beyond a one-semester course.</jats:p>

Developing a flexible learning activity on biodiversity and spatial scale concepts using open‐access vegetation datasets from the National Ecological Observatory Network

“…Our experience highlights both the need for additional training and mentorship opportunities for PUI faculty (Bonner et al, 2017) and the need for open-access data repositories such as NEON to consider ways to improve accessibility for faculty experiencing technology constraints. For example, not all faculty are comfortable with how to download and run an R or Python code to compile data from the NEON portal, so although it is extremely helpful to have those tools, they may not be enough to provide access to NEON data for many PUI faculty (Auker & Barthelmess, 2020).…”

Teaching quantitative ecology online: An evidence‐based prescription of best practices

“…Computational exercises can be very useful tools to teach complex quantitative topics. Still, recent research emphasizes that modeling and programming are fundamentally different skills (Auker & Barthelmess, 2020). For many students, our quantitative ecology courses would be their first experience with computer programming.…”

An introduction to agent‐based models as an accessible surrogate to field‐based research and teaching

“…Experience with quantitative methods is becoming increasingly important within ecology and evolution as technology and high‐frequency data are heavily used in research (Auker & Barthelmess, 2020; Sherin, 2011). Undergraduate and masters level thesis projects are often students' first attempt at completing an end‐to‐end research project, and this experience is viewed as a proxy for future success and entry to graduate‐level research (Narayanan, 1999).…”
