For the Winter 2024 issue of Science Education and Civic Engagement: An International Journal, we are delighted to feature two project reports and an engaging conversation from the 2023 SENCER Summer Institute. These contributions reflect a variety of creative connections between science education and civic engagement.
Kerri Shelton from Columbus State University in Georgia reports on work done by a team of undergraduate researchers (chemistry and nursing majors) who worked to analyze 20th-century medical kits at the Columbus Museum. The analysis provided museum staff with information that will help in the proper curation and storage of the kits. In addition, the information gathered provided the Columbus community with a better understanding of medically related items in the 20th century. The work described in the project report is a good example of civic engagement benefitting a community by increasing the understanding of its own history. (download the PDF here)
This project report describes the process of a team of undergraduate researchers (Chemistry and Nursing majors), who analyzed 20th-century medical kits housed at The Columbus Museum (Columbus, GA, USA). Curators and museum personnel were unfamiliar with the contents and needed assistance in identifying the various chemical contents. Items were identified by the Taylor Lab, which was followed by fully elucidating the chemical information in a chemical report and student-curated exhibit. The intent of this project was to help the museum be aware of how to properly curate and store the medical collections for an extended period. Laboratory analyses were executed to determine the composition of the aged items in the collections. The historical context of these kits and their contents provided knowledge of medicine to the community of Columbus, Georgia, in addition to explaining the use of medically related items in the 20th century.
Providing safe access to functional field experiences during the early stages of the COVID-19 pandemic was a distinct challenge. However, these experiences are critical to train students in ecological methods and provide an opportunity for open-ended, authentic research. Here, we report on a multi-week lab designed for an introductory ecology course, which was adapted for hybrid instruction during the pandemic. In the lab sequence, students independently surveyed basic phenological, population, and community dynamics of easily identifiable, cosmopolitan plant species in the genus Plantago. Students used this crowd-sourced dataset to develop, analyze, and report on unique research questions regarding interactions between Plantago and the local environment. The new lab sequence effectively met course learning objectives in experimental design, field methods, statistics, and science communication, while being accessible to both in-person and online learners. We conclude by discussing the evolution of this design for other audiences.
Course-based undergraduate research experiences (CUREs) promote early and expanded student engagement in scientific research that improves science literacy, analytical skills, and inclusivity within STEM majors (e.g., Bangera & Brownell, 2014; Olimpo et al., 2018). Incorporating academic research interests and novel pedagogies benefits both student and faculty development (Shortlidge et al., 2016). However, the transition to online education during the COVID-19 pandemic posed many challenges to the implementation of such lab experiences (Tsang et al., 2021).
Institutions adopted myriad strategies for course delivery early in the pandemic, including distanced labs, hybrid formats, and asynchronous learning. Purely online simulations or recordings of experiments did not maintain student engagement and led to a superficial understanding of lab methodology or purpose (Sansom, 2020). Several methods to promote active participation in remote labs were later adopted, including computer simulations and ecological field research (Abriata, 2022; Creech & Shriner 2020), although it was important to ensure equal accessibility for all students using hands-on modalities (Jawad et al., 2021; Kelley, 2020). These rapid shifts to new modalities and implementation of new technologies induced anxiety and revealed inequity among students (Tsang et al., 2021). Feelings of isolation were common, making it difficult for students to establish a routine and remain motivated from home (Feldman, 2020). The pandemic also triggered emotional stressors caused by direct illness, grief, financial instability, and loneliness and led to physical and mental health issues including disordered eating and depression (Flaudias et al., 2020; Mushquash & Grassia, 2020). Within a semester of teaching during COVID-19, it became clear that pedagogical modalities should acknowledge and accommodate evolving student needs.
Truman State University is a rural public liberal arts university of under 4,000 undergraduate students located in Kirksville, MO. During this study (2020), Truman State had a 72% acceptance rate, the gender identity at Truman was 40:60 identifying male:female, and approximately 80% were white, in-state, and received financial aid. Truman has a long-standing reputation in the Midwest as an affordable, quality public college option. As at many universities across the United States, enrollment has been steadily declining at Truman; undergraduate enrollment is down approximately 35% in the past five years. Biology is a consistently popular major that accounts for 12% of incoming freshmen, but enrollment has declined more than 50% since 2017. Recently, the Biology department implemented a new curriculum for the major. Biology majors who started before fall 2019 were required to take Introduction to Ecology (BIOL 301); after the curriculum change, BIOL 301 was one of four organismal biology course options. With many Truman students pursuing careers in medicine or healthcare, microbiology has proven more popular than ecology or the other two organismal courses (evolutionary biology and eukaryotic diversity). Since the new curriculum has been implemented, student demand for ecology has steadily decreased from six 24-seat sections per year in 2017 to a single section in 2022.
Course instructors (Drew Sieg and Joanna Hubbard, hereafter RDS and JKH) collaborated extensively to develop materials for this model; they restructured the learning management system, co-developed asynchronous recorded lectures and lecture activities, and held weekly meetings to discuss how the hybrid course was supporting student success and wellness. A full comparison of course changes to accommodate a hybrid delivery are listed in Table 1. Pre- and post-surveys evaluating student skills in science communication, statistics, and graphical interpretation were issued, but IRB approval was not established until after implementation of this project. Thus, evaluative feedback on this study is limited to voluntary course evaluations administered for all Truman courses and reflects the pedagogy of the course as a whole, rather than just the new lab experience. As both instructors taught sections in 2019 and 2020, comparisons between years were made to evaluate changes in student perceptions due to both COVID-19 and the intervention.
In pre-COVID semesters, BIOL 301 students would survey water quality and macroinvertebrate diversity from local streams to acquire field experience (modified from Doherty et al., 2011). Sampling sites were located up to 30 minutes from campus, which required university transportation and longer lab periods, neither of which were feasible using a hybrid model. For the new field experience, we expanded on a survey protocol for Plantago lanceolata and P. rugelii used by Rachel Penczykowski (RMP) to train students in the Tyson Undergraduate Fellows program at Washington University in St. Louis. Plantago are short-lived perennials commonly found in human-disturbed habitats, including lawns, parks, paths, and pastures. The geographic distributions of these species span gradients in latitude, elevation, urbanization, and other environmental factors. They are easy to find and identify, are regionally abundant, of low conservation concern, and extremely accessible (Penczykowski & Sieg, 2021). They are suitable for addressing research questions at the population or community level, due to their distinct phenological stages and easily recognizable evidence of interactions with both herbivores and fungal pathogens (Penczykowski & Sieg, 2021).
Three labs interspersed throughout the semester were developed to encompass the Plantago field experience. In addition to the instructional goal of providing an effective hybrid learning experience, student outcomes from the experience included the ability to
The first lab established the utility of Plantago as a model organism for ecological research. Students watched a 13-minute recorded video by RMP discussing how the species can be used to address questions at multiple spatial scales across varying environment types. Connections to climate change and urban development were stressed, along with the use of cosmopolitan Plantago species in global collaborations including PlantPopNet and HerbVar. This video also emphasized the value of community science engagement and collaborative research across universities.
Following the video, students were trained to identify focal species, their flowering status, types of herbivory damage, and evidence of infection by a fungal pathogen (powdery mildew). These skills were practiced as a group for in-person students, followed by an individual homework assignment. Remote students participated in the training, but practiced individually. Example images were provided via PowerPoint, so that students could participate in synchronous group work in person or via Zoom. Groups also brainstormed research questions and hypotheses, generally focusing on variation in herbivory or infection between species or survey locations.
