In this study, we examined the extent to which students making “broadly relevant novel discoveries” impacted student project ownership by comparing the experiences of students in a CURE and a traditional lab course. The CURE and traditional lab were similar in most aspects; students were exposed to an identical curriculum taught by the same instructor. However, there was one major difference between the two types of courses: the type of data that the students produced. Students in the traditional lab characterized the immune system of wild-type mice, thereby confirming results already known to the scientific community, while students in the CURE characterized the immune system of a mutant strain of mice, which produced broadly relevant novel discoveries. Compared with traditional lab students, CURE studen...

Educating emergent scholars in the principles of ethics/responsible conduct of research (E/RCR) is therefore critical to ensuring such advancement. The recent impetus to include authentic research opportunities as part of the undergraduate curriculum, via course-based undergraduate research experiences (CUREs), has been shown to increase cognitive and noncognitive student outcomes. Because of these important benefits, CUREs are becoming more common and often constitute the first research experience for many students. However, despite the importance of E/RCR in the research process, we know of few efforts to incorporate E/RCR education into CUREs. The Ethics Network for Course-based Opportunities in Undergraduate Research (ENCOUR) was created to address this concern and promote the integration of E/RCR within CUREs in the biological sciences and related disciplines...

A concern these degrees raise is: Will students be prepared for the next step of their career paths after completing their Bachelor’s degree online? Biology undergraduates often begin their degrees wanting to become medical doctors, but no studies have explored whether students in a fully online biology degree program are being prepared to be admitted to medical school. In this study, we surveyed Introductory Biology students at one institution who were pursuing Bachelor of Science degrees in Biological Sciences, either in an online or an in-person program. The most prevalent career goal for both in-person students (65.2%) and online students (39.7%) was a medical doctor. Online students were more confident in their intentions to become doctors than their in-person peers. However, online students knew fewer criteria tha...

While college in general can be stressful, college science classrooms have the potential to be especially anxietyinducing because of the sometimes chilly and competitive environment of the class. Further, college science courses are increasingly being transitioned from traditional lecture to active learning where students take an active role in their learning, often through participating in activities such as clicker questions and group work. There is emerging evidence that suggests active learning activities may cause students to feel anxious, but no studies have thoroughly explored why active learning activities in science courses may increase students' anxiety. Further, no studies have explored whether active learning activities can reduce students' anxiety. In this exploratory interview study of 52 students enrolled in large-enrollment active learning college science courses, we investigate how three active learning practices, clicker questions, group work, and cold call/random call, increase and decrease students' anxiety. Results: Students reported that clicker questions and group work had the potential to both increase and decrease their anxiety. The way the active learning activity is implemented and the extent to which students perceive they benefit from the activity seems to influence the effect of the activity on students' anxiety. Conversely, students reported that cold call and random call only increased their anxiety. From our interviews, we identified the fear of negative evaluation, or the sense of dread associated with being unfavorably evaluated while participating in a social situation, as the primary construct underlying students' high levels of anxiety associated with speaking out in front of the whole class when they do not volunteer. This study illustrates that active learning can both increase and decrease students' anxiety depending on the way active learning is implemented. We hope that this study encourages instructors to create more inclusive active learning science courses by implementing active learning in ways that minimize students' anxiety.

In this study, we administered six evolution acceptance instruments in a single survey to students in undergraduate biology courses at universities in Arizona, Colorado, and Utah. We conducted separate analyses with the same students for the six different evolution acceptance instruments to understand how different results and conclusions may arise based on different evolution acceptance instruments used. Results: We found statistically significant differences in levels of evolution acceptance across the three student populations when using a human evolution acceptance instrument, but not when using a microevolution acceptance instrument. Further, significance/effect sizes of variables associated with evolution acceptance differed beyond sampling variation depending on the evolution acceptance instrument used. The results of analyses using different evolution acceptance instruments were most often dissimilar when examining the effect of evolution understanding and identifying as Protestant/Mormon on evolution acceptance. Conclusions: We found that different instruments used to measure evolution acceptance sometimes led to different research results and conclusions. The extent to which variables predicted evolution acceptance was dependent on the instrument used to measure acceptance, which has the potential to explain over 30 years of conflicting research on the relationship between evolution acceptance and understanding. These results indicate that before researchers may be able to determine how to best improve evolution acceptance, the evolution education community may need to articulate a consistent definition of evolution acceptance and identify a singular valid and reliable instrument to quantify evolution acceptance so results can be compared across studies.

While identifying these concepts was an important first step, departments also need ways to measure the extent to which students understand these concepts. Here, we present the General Biology–Measuring Achievement and Progression in Science (GenBio-MAPS) assessment as a tool to measure student understanding of the core concepts at key time points in a biology degree program. Data from more than 5000 students at 20 institutions reveal that this instrument distinguishes students at different stages of the curriculum, with an upward trend of increased performance at later time points. Despite this trend, we identify several concepts that advanced students find challenging. Linear mixed-effects models reveal that gender, race/ethnicity, English-language status, and first-generation status predict overall performance and that differen...

This difference in religious beliefs and cultures may be a barrier to effective evolution education. To explore when evolution instructors have similar religious cultures and beliefs as their students, we interviewed 32 evolution instructors at Christian universities nationwide about their practices and experiences teaching evolution. Christian university instructors emphasized teaching for acceptance of evolution while holding an inclusive teaching philosophy that they perceived led to a safe environment for students. Additionally, almost all instructors reported using practices that have been shown to increase student acceptance of evolution and reduce student conflict between evolution and religion. Further, we found that these instructors perceived that their own religious backgrounds have guided their decisions to teach evolution to their students in a culturally competent way. We discuss how these data, combined with past research literature on public college instructors, indicate that cultural competence could be a useful new framework for promoting effective evolution education in higher education institutions.

Over-arching principles of evolutionary medicine have been described in publications, but our study is the first to systematically elicit core principles from a diverse panel of experts in evolutionary medicine. These principles should be useful to advance recent recommendations made by The Association of American Medical Colleges and the Howard Hughes Medical Institute to make evolutionary thinking a core competency for pre-medical education. The Delphi method was used to elicit and validate a list of core principles for evolutionary medicine. The study included four surveys administered in sequence to 56 expert panelists. The initial open-ended survey created a list of possible core principles; the three subsequent surveys winnowed the list and assessed the accuracy and importance of each principle. Results: Fourteen core principles elicited at least 80% of the panelists to agree or strongly agree that they were important core principles for evolutionary medicine. These principles over-lapped with concepts discussed in other articles discussing key concepts in evolutionary medicine. Conclusions and implications: This set of core principles will be helpful for researchers and instructors in evolutionary medicine. We recommend that evolutionary medicine instructors use the list of core principles to construct learning goals. Evolutionary medicine is a young field, so this list of core principles will likely change as the field develops further.

As college biology classrooms transition from lecturing to active learning, students interact more with each other and are likely comparing themselves more to other students in the class. Student characteristics can impact students’ academic self-concept; however, this has been unexplored in the context of undergraduate biology. In this study, we explored whether student characteristics can affect academic self-concept in the context of an active learning college physiology course. Using a survey, students self-reported how smart they perceived themselves to be in the context of physiology relative to the whole class and relative to their groupmate, the student with whom they worked most closely in class. Using linear regression, we found that men and native English speakers had significantly higher academic self-concept relative to the whole cl...

Aligned with the conceptual frameworks of Core Principles of Physiology, and Vision and Change Core Concepts, Phys-MAPS can be used to evaluate student learning of core physiology concepts at multiple time points in an undergraduate physiology program, providing a valuable longitudinal tool to gain insight into student thinking and aid in the data-driven reform of physiology curricula. Phys-MAPS questions have a modified multiple true/false design and were developed using an iterative process, including student interviews and physiology expert review to verify scientific accuracy, appropriateness for physiology majors, and clarity. The final version of Phys-MAPS was tested with 2,600 students across 13 universities, has evidence of reliability, and has no significant ...

To date, promoting and sustaining pedagogical change through different initiatives has proven difficult, but research on pedagogical change is advancing. To this end, we examine pedagogical behaviors through a cultural evolutionary model that stresses the global nature of the issue, the generational time that change requires, and complications introduced by academic career trajectories. We first provide an introduction to cultural evolutionary theory before describing our model, which focuses on how cultural transmission processes and selection events at different career phases shape not only who teaches in higher education, but also how they choose to teach. We leverage our model to make suggestions for expediting change in higher education. This includes reforming pedagogy in depa...

Although evolution and religion are potentially compatible, students' perceived conflict between their religious beliefs and evolution can negatively affect their acceptance of evolution. In a previous study, we found that illustrating the potential compatibility of religion and evolution decreased the number of students who perceived a conflict between religion and evolution by 53 percent. However, in the previous study, the instruction on the potential compatibility of religion and evolution took a significant amount of instructional time, which could be a barrier for implementation. In this current study, we condensed the instruction illustrating the potential compatibility of religion and evolution to six minutes. By conducting qualitative analyses on data gathered from ten students who perceived a conflict before the evolution module, we found that eight of these students reduced thei...

However, no study has explored humor exclusively in the context of college science courses, which have the reputation of being difficult and boring. The majority of studies that explore humor have assumed that students perceive instructor humor to be funny, yet students likely perceive some instructor humor as unfunny or offensive. Further, evidence suggests that women perceive certain subjects to be more offensive than men, yet we do not know what impact this may have on the experience of women in the classroom. To address these gaps in the literature, we surveyed students across 25 different college science courses about their perceptions of instructor humor in college science classes, which yielded 1637 student responses. Open-coding methods were used to analyze student responses to a question about why students appreciate humor. Multinomial regression wa...

There is support for the use of videos in which instructors tutor students, but few studies have been conducted within the context of a classroom. In this study, conducted in a large-enrollment college physiology course, we used a randomized crossover design to compare the impact of two types of instructor-generated videos that students watched as part of their preclass assignments. We compared videos featuring only an instructor (instructor-only videos) with videos featuring an instructor tutoring a student (instructor-tutee videos). We analyzed student survey responses and weekly physiology quiz scores and found that students preferred, enjoyed, and valued the instructor-only videos significantly more than the instructor-tutee videos. In contrast to prior literature, students with a grade point average (GPA) below the median (...
