Over the last decade, reform in science education has placed an emphasis on the science practices as a way to engage students in the process of science and improve scientific literacy. A critical component of developing scientific literacy is learning to apply quantitative reasoning to authentic scientific phenomena and problems. Students need practice moving fluidly (or fluently) between math and science to develop a habit of mind that encourages the application of quantitative reasoning to real-world scenarios. Here we present a student-facing model that challenges students to think across these two fields. The model brings together math and science with a goal to increase scientific literacy by engaging students in quantitative reasoning within the context of scientific questions and phenomena. In the classroom, the model serves to help students visualize the logical and necessary moves they make as they use quantitative reasoning to connect science practices with mathematical thinking. 

In this essay, we review how counter-stereotypical scientists have been featured in life science courses and discuss the benefits and costs of developing and interacting with these materials from the perspectives of three groups: students, instructors, and the featured scientists. 

Undergraduate introductory STEM courses often rely on few, high-stakes exams to assess student learning. This assessment strategy engenders high test anxiety and negatively impacts academic performance. We know little about how students want to be assessed—particularly those who experience high test anxiety. Applying a humanist learning framework, we asked students at a university in Norway to envision their ideal assessment practice. Our analyses affirm that test anxious students performed worse in their STEM courses, and students with marginalized identities in STEM were more test anxious. Additionally, we found that students overwhelmingly want more assessments. We also found that first-generation students, a student group rarely studied in Norway, want different types of assessments to replace high-stakes exams. In sum, student preferences aligned with assessment practices known to reduce the impact of test anxiety. Our results support calls for creating STEM environments where student voices are valued. 

Despite broad consensus that highlighting counter-stereotypical scientist role models in educational materials promotes equity and success, the specific elements that make these materials effective remain untested. Are pictures of counter-stereotypical scientists enough to communicate to students that scientists come from a variety of backgrounds, or is additional information required? To parse the effects of including visual depictions and humanizing information about scientists featured in biology course materials, we distributed three randomized versions of assignments over several academic terms across 36 undergraduate institutions (n> 3700 students). We found that including humanizing information about scientists was key to increasing student engagement with the biology course materials. The positive effect of humanizing information was especially important for students who related to the scientists. Structural equation modelling revealed the extent to which students related to scientists mediated the positive effect of humanizing descriptions on student engagement. Furthermore, our results were strongest among students who shared one or more excluded identity(s) with the featured scientists. Our findings underscore the importance of providing students with examples of humanized and relatable scientists in classrooms, rather than simply adding a photo to increase representation. 

Featuring a diversity of scientists within curriculum provides opportunities for students to relate to them. We manipulated the amount and type of information students received about scientists. We found including personal, humanizing information increased the extent to which students related to them, with implications for curriculum development. 

Discipline-based education research—a field of research that investigates teaching and learning within STEM disciplines—has emerged over the last few decades to improve the quality of STEM education worldwide. Simple qualitative questions concerning the career backgrounds and motivations of the individuals who conduct this research have yet to be explored. Here, we surveyed and interviewed discipline-based education researchers about their career trajectories and motivations to pursue this field of research. We focused specifically on recruiting biology education research faculty members at colleges and universities. We used the Social Influence Model and Social Cognitive Career Theory to develop and analyze survey and semi-structured interview questions. Findings revealed participant career paths all began with disciplinary undergraduate and graduate-level biology education. We noticed participants began conducting biology education research due to theirvaluesandpersonal interests, while additionally being swayed bycontextual factors. Specifically, participantsvaluedbiology education research because it allowed them to make a difference in the world and provided them with a community open to change and collaboration. Biology education research allowed them to explore theirinterestsin teaching and evidence-based approaches to education. Thesevaluesandinterestswere impacted bycontextual factors, including discoveries of opportunities, positive (or negative) experiences with mentorship, exposure to evidence-based teaching literature, considerations of salary and job security, and experiences with gender-based discrimination. Our results underscore the importance of harnessing individual values and interests—especially those centered on evidence-based teaching practices and making a difference in the world—while fostering a positive and supportive academic environment. This research reveals pathways toward discipline-based education research careers. Additionally, this research can inform the development of graduate programs and funding opportunities. 

Abstract Background We used an opportunity gap framework to analyze the pathways through which students enter into and depart from science, technology, engineering, and mathematics (STEM) degrees in an R1 higher education institution and to better understand the demographic disparities in STEM degree attainment. Results We found disparities in 6-year STEM graduation rates on the basis of gender, race/ethnicity, and parental education level. Using mediation analysis, we showed that the gender disparity in STEM degree attainment was explained by disparities in aspiration: a gender disparity in students’ intent to pursue STEM at the beginning of college; women were less likely to graduate with STEM degrees because they were less likely to intend to pursue STEM degrees. However, disparities in STEM degree attainment across race/ethnicities and parental education level were largely explained by disparities in attrition: persons excluded because of their ethnicity or race (PEERs) and first generation students were less likely to graduate with STEM degrees due to fewer academic opportunities provided prior to college (estimated using college entrance exams scores) and more academic challenges during college as captured by first year GPAs. Conclusions Our results reinforce the idea that patterns of departure from STEM pathways differ among marginalized groups. To promote and retain students in STEM, it is critical that we understand these differing patterns and consider structural efforts to support students at different stages in their education. 

Traditional biology curricula depict science as an objective field, overlooking the important influence that human values and biases have on what is studied and who can be a scientist. We can work to address this shortcoming by incorporating ideological awareness into the curriculum, which is an understanding of biases, stereotypes, and assumptions that shape contemporary and historical science. We surveyed a national sample of lower-level biology instructors to determine 1) why it is important for students to learn science, 2) the perceived educational value of ideological awareness in the classroom, and 3) hesitancies associated with ideological awareness implementation. We found that most instructors reported “understanding the world” as the main goal of science education. Despite the perceived value of ideological awareness, such as increasing student engagement and dispelling misconceptions, instructors were hesitant to implement ideological awareness modules due to potential personal and professional consequences. 

Addressing the challenges facing society and the world will require an understanding of the biases and limitations of science. To combat these challenges, here, we advocate for the incorporation of ideologically aware (IA) material into postsecondary biology curricula. IA materials communicate to students how biases, assumptions, and stereotypes inform approaches to and outcomes of science. By engaging with IA materials, student awareness of the impact of science on social problems is expected to increase. In this paper, we situate this IA approach with two other pedagogical approaches that incorporate societally relevant content: culturally relevant pedagogy and socioscientific issues. We then call for research to test ways of supporting instructor implementation of IA material, to evaluate the impact of IA topics on student academic and sociopsychological outcomes, and to explore how to implement IA material in different cultural and social settings. Throughout, we focus on IA topics in the context of postsecondary biology classrooms but encourage the incorporation of IA materials across scientific disciplines and educational settings. Our hope is that greater inclusion of IA materials will create more transparent, scientifically accurate, and inclusive classrooms.
