Many factors have been proposed to explain the attrition of women in science, technology, engineering and math fields, among them the lower performance of women in introductory courses resulting from deficits in incoming preparation. We focus on the impact of mixed methods of assessment, which minimizes the impact of high-stakes exams and rewards other methods of assessment such as group participation, low-stakes quizzes and assignments, and in-class activities. We hypothesized that these mixed methods would benefit individuals who otherwise underperform on high-stakes tests. Here, we analyze gender-based performance trends in nine large (N > 1000 students) introductory biology courses in fall 2016. Females underperformed on exams compared to their male counterparts, a difference that does not exist with other methods of assessment that compose course grade. Further, we analyzed three case studies of courses that transitioned their grading schemes to either de-emphasize or emphasize exams as a proportion of total course grade. We demonstrate that the shift away from an exam emphasis consequently benefits female students, thereby closing gaps in overall performance. Further, the exam performance gap itself is reduced when the exams contribute less to overall course grade. We discuss testable predictions that follow from our hypothesis, and advocate for the use of mixed methods of assessments (possibly as part of an overall shift to active learning techniques). We conclude by challenging the student deficit model, and suggest a course deficit model as explanatory of these performance gaps, whereby the microclimate of the classroom can either raise or lower barriers to success for underrepresented groups in STEM.

Background: Understanding student motivational factors such as test anxiety and science confidence is important for increasing retention in science, technology, engineering, and math (STEM), especially for underrepresented students, such as women. We investigated motivational metrics in over 400 introductory biology students in Norway, a country lauded for its gender equality. Specifically, we measured test anxiety and science confidence and combined students’ survey responses with their performance in the class. Results: We found that female students expressed more test anxiety than did their male counterparts, and the anxiety they experienced negatively predicted their performance in class. By contrast, the anxiety male students experienced did not predict their performance. Conversely, men had higher confidence than women, and confidence interacted with gender, so that the difference between its impact on men’s and women’s performance was marginally significant. Conclusions: Our findings have implications for STEM instructors, in Norway and beyond: specifically, to counter gender-based performance gaps in STEM courses, minimize the effects of test anxiety.

We report on a brief, simple, online course intervention designed to reduce identity gaps and help students see their “possible selves” in working scientists. Students ( n = 238) in a large-enrollment, introductory biology course for nonmajors were assigned nine podcasts, distributed throughout the semester. These podcasts each featured a scientist telling a “true, personal story about science,” and we intentionally selected podcasts featuring scientists from diverse backgrounds. We hypothesized that this intervention would serve to broaden student perceptions of science and scientists, and we used a mixed-methods approach to analyze (a) survey data and (b) short written responses about how these podcasts impacted students’ views of the people who do science. Student survey responses confirm that students overwhelmingly found the podcasts valuable, engaging, and relatable, and student impressions varied as a function of student identity (gender, religiosity, sexual orientation, etc.). Further, these podcasts changed student perceptions of the sort of people who do science. This work builds on earlier findings and expands the current work to include a look at how students from a range of different identities—hidden and visible—respond to a simple intervention designed to counter stereotypes about scientists.

Recent calls to action urge sweeping reform in science education, advocating for improved learning for all students—including those majoring in fields beyond the sciences. However, little work has been done to characterize the differences—if any exist—between students planning a career in science and those studying other disciplines. We describe an attempt to clarify, in broad terms, how non–STEM (science, technology, engineering, and mathematics) majors differ from life sciences majors, and how they are similar. Using survey responses and institutional data, we find that non–STEM majors are not unilaterally science averse; non–STEM majors are more likely than biology majors to hold misconceptions about the nature of science, yet they are not completely ignorant of how science works; non–STEM majors are less likely than biology majors to see science as personally relevant; and non–STEM majors populations are likely to be more diverse—with respect to incoming knowledge, perceptions, backgrounds, and skills—than a biology majors population. We encourage science educators to consider these characteristics when designing curricula for future scientists or simply for a well-informed citizenry.

The coronavirus disease 2019 (COVID‐19) pandemic introduced an abrupt change in human behavior globally. Here, we discuss unique insights the pandemic has provided into the eco‐evolutionary role of pathogens in ecosystems and present data that indicates the pandemic may have fundamentally changed our learning choices. COVID‐19 has indirectly affected many organisms and processes by changing the behavior of humans to avoid being infected. The pandemic also changed our learning behavior by affecting the relative importance of information and forcing teaching and learning into a framework that accommodates human behavioral measures to avoid disease transmission. Not only are these indirect effects on the environment occurring through a unique mechanistic pathway in ecology, the pandemic along with its effects on us provides a profound example of the role risk can play in the transmission of information between the at risk. Ultimately, these changes in our learning behavior led to this special issue “Taking learning online in Ecology and Evolution.” The special issue was a call to the community to take learning in new directions, including online and distributed experiences. The topics examined include a significant component of DIY ecology and evolution that is experiential but done individually, opportunities to use online tools and apps to be more inclusive, student‐focused strategies for teaching online, how to reinvent conferences, strategies to retain experiential learning safely, emerging forms of teaching such as citizen science, apps and podcasting, and ideas on how to accommodate ever changing constraints in the college classroom, to name a few. The collective consensus in our fields is that these times are challenging but we can continue to improve and innovate on existing developments, and more broadly and importantly, this situation may provide an opportunity to reset some of the existing practices that fail to promote an effective and inclusive learning environment.

Scientific disciplines face large diversity challenges, with the fields of ecology and evolution being among the most homogeneous—specifically with respect to race and ethnicity. These problems have been recently compounded by large‐scale racial unrest, highlighting some of the underlying disparities that have led to these diversity challenges, and a global pandemic, which, by moving instruction online, has created new challenges for inclusive teaching. Among the inclusive‐teaching techniques that can be implemented during remote instruction are Scientist Spotlights—role‐model interventions that use available online materials to highlight the work of scientists representing multiple axes of diversity. We report here on the implementation of Scientist Spotlights in two courses, both of which emphasize ecology and evolution. We conclude with sample resources and suggestions for adopters.
