We examined how the shift in learning environment from in-person to online classes, due to the COVID-19 pandemic, impacted three constructs of student engagement: behavioral engagement, including students’ frequency of participating in class discussions, meeting with instructors, and studying with peers outside of class; cognitive engagement, including students’ sense of belonging and self-efficacy; and emotional engagement, including students’ attitudes toward science, their perceived value of the course, and their stress. Seventy-three undergraduate STEM students from across the country completed five-point Likert-style surveys in these areas of student engagement, both prior to their science course transitioning online and at the end of the spring 2020 semester.
Academic integrity establishes a code of ethics that transfers over into the job force and is a critical characteristic in scientists in the twenty-first century. A student’s perception of cheating is influenced by both internal and external factors that develop and change through time. For students, the COVID-19 pandemic shrank their academic and social environments onto a computer screen. We surveyed science students in the United States at the end of their first COVID-interrupted semester to understand how and why they believed their peers were cheating more online during a pandemic. Almost 81% of students indicated that they believed cheating occurred more frequently online than in-person. When explaining why they believed this, students touched on proctoring, cheating influences, and extenuating circumstances due to COVID-19. When describing how they believed cheating occurred more frequently online, students touched on methods for cheating and surreptitious behavior. The student reasonings were associated with four theories (game theory, Kohlberg’s theory of moral development, neutralization theory, and planned behavior theory) that have been used to examine academic dishonesty. Our results can aid institutions in efforts to quell student concerns about their peers cheating during emergencies. Interestingly, most student beliefs were mapped to planned behavior theory while only a few students were mapped to neutralization theory, suggesting it was a novel modality of assessment rather than a pandemic that shaped student perceptions.
Biology faculty across the United States were surveyed to chronicle their experiences with the COVID-19 emergency transition to remote teaching. Polarizing differences were seen in faculty responses based on previous experience teaching online and formal training received. The results underline the importance of training and highlight difficulties to address.
Societal Impact StatementHumans are dependent upon plants for oxygen, food, textiles, and medicines. Climate change and deforestation represent serious threats to our planet, causing significant disruptions to our ability to access and utilize these plant resources; this makes a botanically literate workforce and plant science careers more important than ever. Unfortunately, the current state of botanical career opportunities and training programs in the United States remains unclear. This study focuses on the current employment trends of government and private sector botanists and what skills future plant scientists will need to be successful in these careers.Summary Plant science plays a crucial role in our society and in ongoing efforts to address many global challenges, including food insecurity and climate change. Yet, despite a predicted increase in plant science career opportunities in the United States, the botanical career landscape outside of academia is not well understood. To further our understanding of the training required for non‐academic botanical careers, the botanical sub‐disciplines used on the job, and career challenges faced by plant scientists, we surveyed 61 scientists working in government and 59 scientists working in the private sector in the United States. In both career sectors, > 80% of survey participants reported recent hires at the bachelor's degree level. New personnel with master's degrees were more commonly reported in the government sector (95%) than in the private sector (69%). Most plant scientists working in government reported a focus on plant ecology and resource management. By contrast, most industry/non‐profit work involved horticulture and biotechnology, with some specific skills spanning both sectors. Notably, one prediction made nearly a decade ago appears to be manifesting: plant scientists seem to be retiring more quickly than they are being replaced. Survey respondents reported that attempts to hire full‐time staff are met with obstacles, including insufficient funding. Plant science professionals in both career sectors emphasized their routine use of botanical skills developed as students, highlighting the need for effective training at the undergraduate level. We discuss the implications of these findings and present several recommendations for preparing future generations of plant scientists and increasing the scientific community's botanical capacity.
Range expansions are key demographic events driven by factors such as climate change and human intervention that ultimately influence the genetic composition of peripheral populations. The expansion of the Virginia opossum (Didelphis virginiana Kerr, 1792) into Michigan has been documented over the past 200 years, indicating relatively new colonizations in northern Michigan. Although most contemporary expansions are a result of shifts in climate regimes, the opossum has spread beyond its hypothesized climate niche, offering an opportunity to examine the compounding influence that climate change and humans have on a species’ distribution. The genetic consequences of two range expansions were investigated using genotypic data for nine microsatellite markers from opossums collected in Michigan, Ohio, and Wisconsin, USA. Two genetic clusters were identified: one on either side of Lake Michigan. Using general linear models, we found that measurements of genetic diversity across 15 counties are best explained by days of snow on the ground. Next best models incorporate anthropogenic covariates including farm density. These models suggest that opossum expansion may be facilitated by agricultural land development and at the same time be limited by their inability to forage in snow.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
