Quality mentoring promotes graduate student success. Despite an abundance of practical advice, empirical evidence regarding how to match mentees and mentors to form quality mentoring relationships is lacking. Here, we examine the influence of variables theorized to predict mentorship support and quality in a national sample of 565 science doctoral students from 70 universities in 38 states. Our structural equation modeling results indicate that mentor rank, mentee capital, and the relationship matching mechanism (direct admissions, rotations) were not associated with higher-quality relationships...

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...

LGBTQ+ undergraduates have higher attrition from science and engineering (S&E) than straight and cisgender undergraduates and perceive that having LGBTQ+ instructors would benefit them. However, it is unknown how many S&E instructors are LGBTQ+, the extent to which they disclose this information to students, and how disclosure affects all students, both LGBTQ+ and non-LGBTQ+. In study I, we surveyed 108 LGBTQ+ S&E instructors across the U.S. to explore the extent to which they reveal their LGBTQ+ identities across professional contexts and why they reveal or conceal their identities to undergraduates...

Interpreting three-dimensional models of biological macromolecules is a key skill in biochemistry, closely tied to students' visuospatial abilities. As students interact with these models and explain biochemical concepts, they often use gesture to complement verbal descriptions. Here, we utilize an embodied cognition-based approach to characterize undergraduate students' gesture production as they described and interpreted an augmented reality (AR) model of potassium channel structure and function. Our analysis uncovered two emergent patterns of gesture production employed by students, as well as common sets of gestures linked across categories of biochemistry content...

Higher education has evolved in ways that may increase the challenges life science faculty face in providing accommodations for students with disabilities. Guided by Expectancy-Value Theory, we interviewed 34 life sciences faculty instructors from institutions nationwide to explore faculty motivation to create disability-inclusive educational experiences. We found that faculty in our sample perceive that providing most standard accommodations is a manageable but often challenging task. Further, faculty in our sample feel that improving accommodations necessitates additional support from their institutions...

Concealable stigmatized identities (CSIs) are identities that can be kept hidden and carry negative stereotypes. To understand the potential influence instructors have as role models, we must first explore the identities instructors have and whether they disclose those identities to undergraduates. We surveyed national samples of science instructors ( n = 1248) and undergraduates ( n = 2428) at research institutions to assess the extent to which instructors hold CSIs, whether they reveal those identities to undergraduates, how the prevalence of CSIs among instructors compares to their prevalence among undergraduates, and the reasons instructors reveal or conceal their CSIs...

First-generation (FG) college students (i.e., those for whom neither parent/guardian obtained a bachelor's degree) experience more barriers in college, compared with continuing-generation students. These barriers are compounded by subtle messages from instructors that convey the idea that natural talent is necessary for success in scientific fields. In contrast, growth mindset messages communicate that ability can improve with effort, help-seeking, and using productive study strategies. In a large enrollment introductory biology course, students were randomly assigned to receive email messages from their instructor after the first two exams containing either a growth mindset or control message...

There is widespread recognition that undergraduate students in the life sciences must learn how to work in teams. However, instructors who wish to incorporate teamwork into their classrooms rarely have formal training in how to teach teamwork. This is further complicated by the application of synonymous and often ambiguous terminology regarding teamwork that is found in literature spread among many different disciplines. There are significant barriers for instructors wishing to identify and implement best practices...

Existing research has investigated student problem-solving strategies across science, technology, engineering, and mathematics; however, there is limited work in undergraduate biology education on how various aspects that influence learning combine to generate holistic approaches to problem solving. Through the lens of situated cognition, we consider problem solving as a learning phenomenon that involves the interactions between internal cognition of the learner and the external learning environment. Using phenomenography as a methodology, we investigated undergraduate student approaches to problem solving in biology through interviews...

Stronger metacognitive regulation skills and higher self-efficacy are linked to increased academic achievement. Metacognition and self-efficacy have primarily been studied using retrospective methods, but these methods limit access to students' in-the-moment metacognition and self-efficacy. We investigated first-year life science students' metacognition and self-efficacy while they solved challenging problems, and asked: 1) What metacognitive regulation skills are evident when first-year life science students solve problems on their own? and 2) What aspects of learning self-efficacy do first-year life science students reveal when they solve problems on their own? Think-aloud interviews were conducted with 52 first-year life science students across three institutions and analyzed using content analysis...

Genetic variation is historically challenging for undergraduate students to master, potentially due to its grounding in both evolution and genetics. Traditionally, student expertise in genetic variation has been evaluated using Key Concepts. However, Cognitive Construals may add to a more nuanced picture of students' developing expertise. Here, we analyze the occurrence of Key Concepts and Cognitive Construals among three types of student representations: interviews, drawn models, and constructed responses (CRs)...

Many students who enroll in a public U.S. 4-y college will not graduate. The odds of completing a college degree are even lower for students who have been marginalized in higher education, especially in Science, Technology, Engineering, and Math (STEM) fields. Can undergraduate research increase a student's likelihood of graduating college and close educational equity gaps in college completion? To answer this question, we use data from six public U.S. universities ( N = 120,308 students) and use Propensity Score Matching to generate a comparison group for analyses...

A "critical access point in the STEM pipeline for Latinx students and other students of color" (Herrera et al. , 2018), community colleges provide a seminal breeding ground for academic pursuits (Bahr et al. , 2017). However, how personal networks influence STEM pathways of two-year college students remains largely unexplored. This mixed methods case study explores influence of personal networks on pursuing STEM fields via social network analysis and qualitative narratives. 36 women of color STEM majors at a two-year urban Hispanic-Serving Institution were interviewed via social network questionnaire...

The purpose of the Current Insights feature is to highlight recent research and scholarship from outside the LSE community. In this installment, I review a series of recently published articles which examine ethical dilemmas concerning the use of artificial intelligence (AI), more specifically machine learning, in science education. The articles in this set are intended to stimulate discussions about whether and how AI can and should be used in education research.

Discipline-based education research (DBER) has experienced dramatic growth over recent years, but with growth comes concerns about whether DBER efforts accurately represent the education landscape. By many measures, DBER does not feature a representative range of institutional contexts or a diverse array of voices. Numerous professional development efforts have sought to broaden DBER participation. However, few studies investigate factors that increase engagement by individuals from underrepresented contexts...

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...

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...

Understanding attitudes towards anthropogenic disturbances, especially among undergraduates, is important to inform educational practices because of the theoretical link between attitude and behavior. We evaluated the attitudes of undergraduate students in a biology majors course and nonmajors course toward two anthropogenic disturbances: wildfire and urbanization. Student attitudes were assessed via an online Wildfire and Urbanization Attitude survey (WUAS) before and after a video intervention, randomly delivered as either fact- or emotion-based versions...
