How Do Students Critically Evaluate Outdated Language That Relates to Gender in Biology?

Cisheteronormative ideologies are infused into every aspect of society, including undergraduate science. We set out to identify the extent to which students can identify cisheteronormative language in biology textbooks by posing several hypothetical textbook questions and asking students to modify them to make the language more accurate (defined as "correct; precise; using language that applies to all people"). First, we confirmed that textbooks commonly use language that conflates or confuses sex and gender. We used this information to design two sample questions that used similar language. We examined what parts of the questions students modified, and the changes they recommended. When asked to modify sample textbook questions, we found the most common terms or words that students identified as inaccurate were related to infant gender identity. The most common modifications that students made were changing gender terms to sex terms. Students' decisions in this exercise differed little across three large biology courses or by exam performance. As the science community strives to promote inclusive classrooms and embrace the complexity of human gender identities, we provide foundational information about students' ability to notice and correct inaccurate language related to sex and gender in biology.

A CURE Lab in Introductory Biology at a Regional Comprehensive University Negatively Impacts Student Success in the Associated Lecture Course Among Students from Groups Underrepresented in Science.

Course-based undergraduate research experiences (CUREs) have been proposed as a mechanism to democratize access to the benefits of apprentice-style scientific research to a broader diversity of students, promoting inclusivity and increasing student success and retention. As we evaluate CUREs, it is essential to explore their effectiveness within the environments of regional comprehensive universities and community colleges, because they are important access points for a wide variety of students. It is also important to address the potential influence of volunteer bias, where students can opt to enroll in either the CURE or a traditional lab, on the outcomes of CUREs. We evaluated a CURE at a regional comprehensive university under conditions both with and without volunteer bias. We find that nonvolunteer students report a lower sense of discovery and relevance of the CURE compared with students who volunteered for the course. Importantly, we also find that our replacement of the traditional lab class with a CURE resulted in lower scores on exams in the associated lecture course among students who are both BIPOC and Pell eligible. We call for additional research on the effects of CUREs at nonresearch-intensive institutions and without volunteer bias, to better understand the impact of these classes.

A Road Map for Planning Course Transformation Using Learning Objectives.

The Vision and Change report called for biology educators to transform undergraduate biology education. The report recommended educators transparently state what students should know and be able to do and create assessments to measure student learning. Using backward design, learning objectives (LOs) can serve as the basis for course transformation. In this essay, we present a roadmap for planning successful course transformations synthesized from the literature. We identified three categories of critical features for successful course transformation. First, establishing a sense of urgency and offering faculty incentives to engage in this time-consuming work creates a needed climate for change. Second, departments are empowered in this process by including key stakeholders, building faculty teams to work collaboratively to identify LOs used to drive pedagogical change, develop assessment strategies, and engage in professional development efforts to support the process. Third, there must be intentional effort to manage resistance and ensure academic freedom and creativity in the classroom. General recommendations as well as areas for further research are discussed.

Undergraduate Biology Lecture Courses Predominantly Test Facts about Science Rather than Scientific Practices.

Scientific practices are the skills used to develop scientific knowledge and are essential for careers in science. Despite calls from education and government agencies to cultivate scientific practices, there remains little evidence of how often students are asked to apply them in undergraduate courses. We analyzed exams from biology courses at 100 institutions across the United States and found that only 7% of exam questions addressed a scientific practice and that 32% of biology exams did not test any scientific practices. The low occurrence of scientific practices on exams signals that undergraduate courses may not be integrating foundational scientific skills throughout their curriculum in the manner envisioned by recent national frameworks. Although there were few scientific practices overall, their close association with higher-order cognitive skills suggests that scientific practices represent a primary means to help students develop critical thinking skills and highlights the importance of incorporating a greater degree of scientific practices into undergraduate lecture courses and exams.

Statements by scientific organizations can, and should, shape society.

Statements based on the best current scientific data and analyses that bear directly on societal issues, especially ones that are critical to societal justice, equity, and health, are practical responsibilities of professional scientific organizations. And they often have impact.

Building conceptual and methodological bridges between SSE's diversity, equity, and inclusion statement and educational actions in evolutionary biology.

The field of evolutionary biology must bridge the gap between its diversity, equity, and inclusion (DEI) commitments and data-driven educational actions in the nation's undergraduate classrooms and degree programs. In this article, we discuss the urgent need for the adoption of equity frameworks and why they are centrally important to data-driven DEI efforts in evolutionary biology. We describe why equity indicators (e.g., measures) must be anchored in and aligned with equity frameworks. We introduce a specific equity framework for learning (the enhanced educational debt framework) and illustrate how it may be leveraged to document, interpret, and improve outcomes in evolutionary biology. We apply the equity framework and associated indicators to >3,500 students' first college-level experience with evolutionary biology at a public, 4-year institution in the Northeastern United States to demonstrate how these conceptual tools and empirical perspectives may be used by faculty, departments, and degree programs to better understand their roles in mitigating or perpetuating inequities. We end by discussing how this framework may be applied to a range of evolution concepts and courses in the educational hierarchy and used to help evolutionary biologists better understand the extent to which a core aspect of SSE's diversity statement is being realized.

Sex and gender essentialism in textbooks.

Several widely used high school biology texts depart from established science.

Metacognitive Exam Preparation Assignments in an Introductory Biology Course Improve Exam Scores for Lower ACT Students Compared with Assignments that Focus on Terms.

Preparing for exams in introductory biology classrooms is a complex metacognitive task. Focusing on lower achieving students (those with entering ACT scores below the median at our institution), we compared the effect of two different assignments distributed ahead of exams by dividing classes in half to receive either terms to define or open-ended metacognitive questions. Completing metacognitive assignments resulted in moderately higher exam scores for students on the second and third exams. Metacognitive assignments also improved accuracy (difference between predicted and actual exam scores) for the second and third exam in lower ACT students, but that improvement was driven largely by higher exam scores in the metacognitive group. Thus, despite the fact that the metacognitive assignments specifically asked students to reflect on their previous exam performance, their previous estimates and predict how well they expected to perform on the exam they were preparing for, there was little evidence that these assignments influenced lower achieving students' confidence levels any more than assignments where students defined terms. While understanding relevant terms was certainly important in this course, these results highlight that open-ended metacognitive prompts may improve exam scores in some students in introductory biology classrooms.

Christian Student Experiences During Peer Interactions in Undergraduate Biology Courses.

The tension between religion and science as a long-standing barrier to science education has led researchers to explore ways of improving the experiences of Christian students in biology who can experience their Christianity as stigmatized in academic biology environments. As undergraduate science classes become student-centered, interactions among students increase, and Christians may feel a need to conceal their religious identities during peer discussions. In this interview study, we used the social psychology framework of concealable stigmatized identities to explore 30 Christian students' experiences during peer interactions in undergraduate biology courses to find potential ways to improve those experiences. We found that students felt their religious identity was salient during peer interactions in biology, and students thought revealing their religious identity to peers in their biology courses could be beneficial, yet few actually did so. Additionally, though most students anticipated stigma, comparatively few had experienced stigma from other students in their biology courses, despite the prior documented cultural stigma against Christians in biology. These results indicate a need for future studies exploring the impact of learning environments in which students are given the opportunity to share their religious identities with one another, which could reduce their anticipated and perceived stigma.

A Study Planning Exercise Associated with Decreased Distraction Levels among Introductory Biology Students.

Students struggle to regulate their learning during independent study sessions. In this study, we ask whether an online behavioral intervention helped introductory students decrease distraction while studying. The intervention consisted of exam 1 reflection, exam 2 planning, and exam 2 reflection exercises. During planning, students formed a goal, mentally contrasted (MC) a positive outcome of their goal to their present reality, identified an obstacle, and formed an implementation intention (II) to overcome that obstacle. During reflection, students self-reported their distraction while studying. Distraction was the most frequently reported study obstacle, and decreasing distraction was the second most frequently reported study goal. While students who aimed to decrease distraction as a goal did not follow through, students who planned for distraction obstacles did follow through on decreasing distraction levels. Only about half of students generated an II that aligned with their study goal, which may provide one reason for the opposing follow-through of distraction framed as a goal versus as an obstacle. Lastly, we examined the specificity of students' II's and found no relationship with follow-through. Overall, MC with II holds promise as a self-regulatory technique to help introductory biology students change their behaviors while studying.

[Interdisciplinary teaching-assisted education reform in "Principal Biology"].

General education in biological courses such as "Principal Biology" is an essential avenue for gaining an understanding of life science and developing an interest in the field. The reform of biological education teaching mode based on interdisciplinary approaches aims to foster cross-disciplinary talents, which is crucial for the rapid development of China's bioeconomy. Teaching method that simply superimposes different subjects is difficult to discover the value of interdisciplinary education. To address this, a novel teaching system and an innovative teaching mode were proposed for "Principal Biology" course by integrating science and engineering subjects, based on the cross-disciplinary feature in Beijing Institute of Technology. The system involves the design of cross-disciplinary course content and the integration of multiple disciplines and knowledge points based on students' majors, taking into account the characteristics of students' physical and mental development. To improve students' scientific literacy and interdisciplinary thinking ability, differentiated and major-driven teaching modes were applied by incorporating the "1+N" mixed and immersive cross-thinking training. The effectiveness of tailored cross-disciplinary teaching was evaluated using "in-teaching" and "post-teaching" data feedback models, which promote the optimization of teaching process and enhance the quality of education in cross-disciplinary biological science.

Investigating the Influence of Assessment Question Framing on Undergraduate Biology Student Preference and Affect.

Nearly all undergraduate biology courses rely on quizzes and exams. Despite their prevalence, very little work has been done to explore how the framing of assessment questions may influence student performance and affect. Here, we conduct a quasi-random experimental study where students in different sections of the same course were given isomorphic questions that varied in their framing of experimental scenarios. One section was provided a description using the self-referential term "you", placing the student in the experiment; another section received the same scenario that used classmate names; while a third section's scenario integrated counterstereotypical scientist names. Our results demonstrate that there was no difference in performance throughout the semester between the sections, nor were there differences in students' self-reported stress and identity. However, students in all three sections indicated that they most preferred the self-referential framing, providing a variety of reasons that suggest that these variants may influence how well a student reads and processes the question. In addition, our results also indicate that the framing of these scenarios can also have a large impact on some students' affect and attitude toward the question. We conclude by discussing implications for the biology education research community and biology instructors.

Assessing Community College Biology Student Perceptions of Being Called on in Class.

Random call has been proposed as an inclusive and equitable practice that engages students in learning. However, this inclusion may come with a cost. In some contexts, students experience anxiety and distress when being called on. Recently, focus has shifted to critical components of random call that may mitigate this cost. We examined how community college (CC) students perceive being called on by addressing 1) benefits that help their learning and 2) characterizing the anxiety students experience through this practice. To do this, we surveyed students in six biology courses taught by six faculty members over six academic quarters. We analyzed survey responses from 383 unique students (520 total responses) using mixed methods. Qualitative responses were coded and consensus codes revealed that students saw benefits to being called on, including paying attention and coming prepared. Qualitative codes also revealed different types of anxiety, both distress and eustress. Analysis of Likert scale survey data revealed perceptions of increased student interaction with their peers in warm random call classes. Furthermore, warm random call may increase participation in class discussions, and it is not correlated with increased extreme anxiety. These data suggest warm random call used in smaller, community college classes, may contribute to students' positive perceptions of being called on.

Re-Envisioning the Culture of Undergraduate Biology Education to Foster Black Student Success: A Clarion Call.

The purpose of this paper is to present an argument for why there is a need to re-envision the underlying culture of undergraduate biology education to ensure the success, retention, and matriculation of Black students. The basis of this argument is the continued noted challenges with retaining Black students in the biological sciences coupled with existing research that implicates science contexts (i.e., the cultural norms, values, and beliefs manifesting through policies and practices) as being the primary source of the challenges experienced by Black students that lead to their attrition. In presenting this argument, we introduce the Re-Envisioning Culture Network, a multigenerational, interdisciplinary network comprised of higher education administrators, faculty, staff, Black undergraduate students majoring in biology, Black cultural artists, community leaders, and STEM professionals to work together to curate and generate resources and tools that will facilitate change. In introducing the REC Network and disseminating its mission and ongoing endeavors, we generate a clarion call for educators, researchers, STEM professionals, students, and the broader community to join us in this endeavor in fostering transformative change.

Gendered Performance Gaps in an Upper-Division Biology Course: Academic, Demographic, Environmental, and Affective Factors.

Despite the existent gender parity in undergraduate biology degree attainment, gendered differences in outcomes are prevalent in introductory biology courses. Less is known about whether these disparities persist at the upper-division level, after most attrition is assumed to have occurred. Here, we report the consistent presence of gender equity gaps across 35 offerings (10 years) of a large-enrollment upper-division biology course at a research-intensive public university. Multilevel modeling showed that women's grades were lower than men's, regardless of prior GPA. These gender gaps were present even when controlling for students' race/ethnicity, socioeconomic status, first-generation college-going status, international status, and transfer status. Class size, gender representation in the classroom, and instructor gender did not significantly relate to course grades. Student questionnaires in a subset of offerings indicated gendered differences in course anxiety, science identity, and science self-efficacy, which correlated with grade outcomes. These results suggest that women experience differential outcomes in upper-division biology, which may negatively influence their persistence in STEM fields postgraduation. Our findings suggest that gender disparities are a systemic problem throughout the undergraduate biology degree and underscore the need for further examination and transformation of upper-division courses to support all students, even at late stages of their degrees.

Postsecondary biology students' ways of participating in the critique and discussion of primary scientific literature.

Science advances through the interplay of idea construction and idea critique. Our goal was to describe varied forms of productive disciplinary engagement that emerged during primary literature discussions. Such descriptions are necessary for biology educators and researchers to design for and recognize diverse repertoires of participation in the critique and discussion of primary scientific literature. We identified three cases (a lower-division ecology course, an upper-division organismal course, and a journal club embedded in a summer research program) that were each designed with weekly primary literature discussions. We analyzed 12 discussions (four from each case) to describe what postsecondary students attend to when they critique and what forms of participation emerged from students reading and discussing primary scientific literature. Students participated in critique in all three cases and patterns in the substance and framing of critiques reflected the level of the context (lower- or upper-division). Students also shaped how they participated in ways that were relevant to the science classroom communities in each case. Our findings suggest that structuring primary literature discussions in ways that both elevate and connect students' agency and personal relevance is important for fostering varied forms of productive disciplinary engagement within a science classroom community.

Forming Groups in a Large-Enrollment Biology Class: Group Permanence Matters More than Group Size.

Active-learning pedagogies often require group work. We tested aspects of forming groups in a nonmajors Biology class. We asked whether large or small groups affected student learning outcomes and attitudes towards working in groups. We placed students in groups of three or six and students stayed in their groups for the term. We measured learning outcomes using a pre/postassessment as well as two-stage exams. Attitudes towards working in groups were measured using a previously published pre/post survey and an exit survey. We found that students in large groups did better on group exams and large groups had higher highest scores on the individual part of two-stage exams. Group size had no effect on students' postassessment scores or attitudes towards working in groups. We next assigned students to permanent or nonpermanent groups. We used the same metrics as the group size experiment. Students in permanent groups had higher group exam scores and better attitudes towards working in groups. Group permanence had no effect on students' postassessment scores. Students preferred working in permanent groups due to positive group interactions that developed over the quarter. Optimal group size and permanence are likely context-specific and dependent on the types of group work used in class.

Intersecting Identities: A Look at How Ethnic Identity Interacts With Science Identity in Native Hawaiian and Pacific Islander Students.

Understanding the experiences of Native Hawaiian and Other Pacific Islander (NHPI) students in science courses can help us foster inclusivity and belonging for these often excluded and unacknowledged students. Using social influence theory as a framework, we investigated the intersection between ethnic-racial identity and science identity in NHPI students to better understand their experiences in undergraduate Biology courses. We collected both quantitative and qualitative data and used concurrent triangulation design in our mixed-methods approach. Quantitative data include measures of student pre- and post-course science identity, self-efficacy, alignment with science values, sense of belonging, environmental concern, strength of ethnic-racial identity, and the interaction between ethnic-racial and science identity. We measured environmental concern because NHPI cultures often have strong connections with the environment that may overlap well with environmental science values. Qualitative data included short responses to survey questions that asked students to describe the interaction between their science identity and their ethnicity. We found that NHPI and non-NHPI students do not significantly differ in any construct we measured, nor do they experience different gains across a semester when comparing pre- and post-scores. We also found that NHPI students' feelings concerning the intersection of their ethnic and science identities are varied and complex, with some students expressing feelings of conflict and many others expressing a strengthening relationship between those identities. We discuss implications for instructors and encourage them to acknowledge the community culture of wealth NHPI students bring to the classroom because of their ethnic-racial identities.

Teaching nature of science in introductory biology: Impacts on students' acceptance of biological evolution.

The present study investigates the impact of explicit, reflective Nature of Science instruction on students' evolution acceptance, understanding of evolution as a theory, and understanding of Nature of Science in an introductory biology course. Results revealed similar improvement in evolution acceptance in both the treatment and control groups, but also that Nature of Science instruction had disproportionately large impacts on evolution acceptance for women and individuals who already had high acceptance. We also found evidence of relationships between understanding and acceptance of evolution and Nature of Science understanding, particularly the creativity aspect of Nature of Science. Together, these results suggest that targeted Nature of Science instruction can have differential impacts on students with particular characteristics, such as women and individuals with high acceptance, but also point to the need to consider additional interventions that can reach men and individuals with low acceptance.
