Online biology degree program broadens access for women, first-generation to college, and low-income students, but grade disparities remain

"Broadening Perspectives Activities" Improve LGBTQ+ Student Experiences and Religious Students' Content Comprehension

Curricular content in undergraduate biology courses has been historically hetero and cisnormative due to various cultural stigmas, biases, and discrimination. Such curricula may be partially responsible for why LGBTQ+ students in STEM are less likely to complete their degrees than their non-LGBTQ+ counterparts. We developed Broadening Perspective Activities (BPAs) to expand the representation of marginalized perspectives in the curriculum of an online, upper-division, undergraduate animal behavior course, focusing on topics relating to sex, gender, and sexuality. We used a quasiexperimental design to assess the impact of the BPAs on student perceptions of course concepts and on their sense of belonging in biology. We found that LGBTQ+ students entered the course with a better understanding of many animal behavior concepts that are influenced by cultural biases associated with sex, gender, and sexuality. However, LGBTQ+ students who took the course with the BPAs demonstrated a greater sense of belonging in biology at the end of the term compared with LGBTQ+ students in the course without BPAs. We also show that religious students demonstrated improved comprehension of many concepts related to sex, gender, and sexuality after taking the course with BPAs, with no negative impacts on their sense of belonging.

A Multi-institutional Cluster Analysis to Identify Groups of Courses with Exemplary Opportunity Gaps for Undergraduate Students in the Biological Sciences

Examining institutional data from seven cohorts of students intending to major in biology across five research-intensive institutions, this work analyzes opportunity gaps-defined as the difference between the grade received by students from the dominant and nondominant sociodemographic groups in institutions of higher education-at the course-section level across mathematics, physics, biology, and chemistry disciplines. From this analysis, we find that the majority of course sections have large opportunity gaps between female and male students, students who are Black, Latino/a/e/x, or indigenous to the United States and its territories and students who are White or Asian, first-generation and non-first-generation students, and low-income and non-low-income students. This work provides a framework to analyze equity across institutions using robust methodology, including: using multiple approaches to measure grades, quantile regression rankscores which adjust for previous academic performance, and cluster analysis. Recommendations are provided for institutions to identify faculty who have equitable course sections, automate equity analyses, and compare results to other institutions to make a change toward more equitable outcomes.

Design and implementation of an asynchronous online course-based undergraduate research experience (CURE) in computational genomics

As genomics technologies advance, there is a growing demand for computational biologists trained for genomics analysis but instructors face significant hurdles in providing formal training in computer programming, statistics, and genomics to biology students. Fully online learners represent a significant and growing community that can contribute to meet this need, but they are frequently excluded from valuable research opportunities which mostly do not offer the flexibility they need. To address these opportunity gaps, we developed an asynchronous course-based undergraduate research experience (CURE) for computational genomics specifically for fully online biology students. We generated custom learning materials and leveraged remotely accessible computational tools to address 2 novel research questions over 2 iterations of the genomics CURE, one testing bioinformatics approaches and one mining cancer genomics data. Here, we present how the instructional team distributed analysis needed to address these questions between students over a 7.5-week CURE and provided concurrent training in biology and statistics, computer programming, and professional development. Scores from identical learning assessments administered before and after completion of each CURE showed significant learning gains across biology and coding course objectives. Open-response progress reports were submitted weekly and identified self-reported adaptive coping strategies for challenges encountered throughout the course. Progress reports identified problems that could be resolved through collaboration with instructors and peers via messaging platforms and virtual meetings. We implemented asynchronous communication using the Slack messaging platform and an asynchronous journal club where students discussed relevant publications using the Perusall social annotation platform. The online genomics CURE resulted in unanticipated positive outcomes, including students voluntarily discussing plans to continue research after the course. These outcomes underscore the effectiveness of this genomics CURE for scientific training, recruitment and student-mentor relationships, and student successes. Asynchronous genomics CUREs can contribute to a more skilled, diverse, and inclusive workforce for the advancement of biomedical science.

Learning in context: Undergraduate students' knowledge and the content retention of anatomy between discipline-specific and integrated course approaches

Undergraduate introductory human anatomy and human physiology courses are either taught as discipline-specific or integrated anatomy and physiology (A&P) sequences. An institution underwent a curricular revision to change the course approach from discipline-specific Human Anatomy and Human Physiology to an integrated A&P I and II sequence, allowing the unique opportunity to explore the potential role of contextual learning in academic achievement and content retention. Mediation and moderation analysis was used to evaluate lecture examinations, laboratory practical examinations, and anatomical content retention between the different course approaches. Undergraduate students in the integrated A&P I course approach performed significantly better on lecture assessments and had a higher anatomy content retention rate at the end of the year than students enrolled in the standalone Human Anatomy course. The lecture examination averages between Human Physiology and A&P II (the second course in the sequence), as well as the anatomy laboratory practical examinations, were not significantly different between discipline-specific and integrated course approaches. The results suggest contextual learning-providing physiological context to anatomical structures-increases the anatomical content retention and academic achievement overall.

Understanding college success through the lens of first-generation students in China: An interpretative phenomenological analysis

Background

First-generation college students face unique challenges in navigating the higher education system, and understanding their perceptions of college success is crucial for providing appropriate support.

Objective

This qualitative study aimed to explore the perceptions of 15 first-generation college students regarding college success and to identify the factors they consider important for achieving success in college.

Method

Semi-structured interviews were conducted with the participants, and the data were analyzed using interpretative phenomenological analysis.

Results

This study explores the varied perceptions of success among first-generation college students (FGCS) through five themes: Academic Achievement, Personal Development, Personal Well-being, Personal Fulfillment, and Career Success.

Conclusion

This study provides valuable insights into the perceptions of first-generation college students regarding college success. The identified themes shed light on the multifaceted nature of success in higher education. These findings have implications for supporting first-generation college students and developing targeted interventions to enhance their overall success and well-being.

Systemic advantage has a meaningful relationship with grade outcomes in students' early STEM courses at six research universities

Background

Large introductory lecture courses are frequently post-secondary students' first formal interaction with science, technology, engineering, and mathematics (STEM) disciplines. Grade outcomes in these courses are often disparate across student populations, which, in turn, has implications for student retention. This study positions such disparities as a manifestation of systemic inequities along the dimensions of sex, race/ethnicity, income, and first-generation status and investigates the extent to which they are similar across peer institutions.

Results

We examined grade outcomes in a selected set of early STEM courses across six large, public, research-intensive universities in the United States over ten years. In this sample of more than 200,000 STEM course enrollments, we find that course grade benefits increase significantly with the number of systemic advantages students possess at all six institutions. The observed trends in academic outcomes versus advantage are strikingly similar across universities despite the fact that we did not control for differences in grading practices, contexts, and instructor and student populations. The findings are concerning given that these courses are often students' first post-secondary STEM experiences.

Conclusions

STEM course grades are typically lower than those in other disciplines; students taking them often pay grade penalties. The systemic advantages some student groups experience are correlated with significant reductions in these grade penalties at all six institutions. The consistency of these findings across institutions and courses supports the claim that inequities in STEM education are a systemic problem, driven by factors that go beyond specific courses or individual institutions. Our work provides a basis for the exploration of contexts where inequities are exacerbated or reduced and can be used to advocate for structural change within STEM education. To cultivate more equitable learning environments, we must reckon with how pervasive structural barriers in STEM courses negatively shape the experiences of marginalized students.

Evaluation of Academic and Nonacademic Factors of First-Generation Students Transitioning to a Pharmacy Program

OBJECTIVE

To evaluate the academic transition of first-generation (FG) students to a Doctor of Pharmacy program and the impact of early intervention/outreach.

METHODS

The retrospective study evaluated the first semester performance in three classes of student pharmacists (beginning fall 2020, 2021, 2022) at a public university in the mid-South. Student demographics (age, sex, race, relationship status), nonacademic factors (Grit, impostor syndrome, testing anxiety, perceived stress), and academic factors (grade point average, academic probation, early intervention) were assessed. In fall 2022, a required academic meeting was added to the early intervention process after exam one for high-risk students. The data between FG and non-FG students were compared; Mann-Whitney tests for continuous variables and Chi-square tests with risk estimates for categorical variables.

RESULTS

There were 152 FG and 274 non-FG students identified over the three classes. A total of 88 (57.9%) FG students represented racial minority groups. More FG students and non-White students were identified for early intervention. First-generation students were more likely to receive two or more grades less than C- and less likely to progress to the spring. No significance was noted with generational status and undergraduate grade point average, academic performance, or nonacademic factors. The required meeting after exam one in fall 2022 resulted in less disparity between FG and non-FG students identified for early intervention for exam two.

CONCLUSION

First-generation and non-White students were more likely to struggle when transitioning to the Doctor of Pharmacy curriculum. A proactive, individualized approach incorporated into early intervention procedures is needed to promote academic success and belonging.

A comparative case study of the accommodation of students with disabilities in online and in-person degree programs

Fully online degree programs are an increasingly important part of the higher education ecosystem. Among the many challenges raised by the growth of fully online courses and degree programs is the question: Are institutions providing online students with disabilities accommodations that are comparable to those provided to students in traditional in-person degree programs? To explore this question, we compared students in a fully online biology degree program to students in the equivalent in-person degree program at a large research university. For each group, we assessed the frequency with which students register with the disability resource center, the range of specific accommodations provided, and course grades. Results show that students in the in-person program were nearly 30% more likely to be enrolled with the disability resource center, and that students in the online program were offered a narrower range of accommodations. However, in relative terms (i.e., compared to students without disabilities in their degree program), online students with disabilities perform better than in-person students with disabilities.

How researchers calculate students' grade point average in other courses has minimal impact

Grade point average in "other" courses (GPAO) is an increasingly common measure used to control for prior academic performance and to predict future academic performance. In previous work, there are two distinct approaches to calculating GPAO, one based on only courses taken concurrently (term GPAO) and one based on all previous courses taken (cumulative GPAO). To our knowledge, no one has studied whether these methods for calculating the GPAO result in equivalent analyses and conclusions. As researchers often use one definition or the other without comment on why that choice was made, if the two calculations of GPAO are different, researchers might be inducing systematic error into their results and publishing potentially inaccurate conclusions. We looked at more than 3,700 courses at a public, research-intensive university over a decade and found limited evidence that the choice of GPAO calculation affects the conclusions. At most, one in seven courses could be affected. Further analysis suggests that there may be situations where one form of GPAO may be preferred over the other when it comes to examining inequity in courses or predicting student grades. However, we did not find sufficient evidence to universally recommend one form of GPAO over the other.

A Comparison of Online and In-Person Evolution Instruction That Includes Religious Cultural Competence

Evolution is one of the most important concepts in biology, but it is rejected by a substantial percentage of religious students due to a perceived conflict with their religious beliefs. The use of religious cultural competence in evolution education (ReCCEE) has been shown to effectively increase evolution acceptance among religious students during in-person instruction, but there is no research that we know of that indicates the effectiveness of these practices during online instruction. In this study, we explored the efficacy of online culturally competent practices for religious students on students' evolution understanding, evolution acceptance, and comfort learning evolution at a religious university. Before and after evolution instruction, we surveyed 178 students in online introductory biology courses and compared these student outcomes to 201 students in the same instructor's in-person introductory biology courses. We found that evolution acceptance and understanding increased in online classes with culturally competent practices, and these gains were similar to those observed in the in-person courses. Despite these similarities, we found that students were more comfortable learning evolution in person than online, but this difference was small. Our findings suggest that the use of culturally competent practices online can be as effective as their use for in-person instruction for improving students' attitudes toward evolution, but in-person instruction may be more effective for cultivating students' comfort while learning evolution.

Remote learning slightly decreased student performance in an introductory undergraduate course on climate change

Public understanding about complex issues such as climate change relies heavily on online resources. Yet the role that online instruction should assume in post-secondary science education remains contentious despite its near ubiquity during the COVID-19 pandemic. The objective here was to compare the performance of 1790 undergraduates taking either an online or face-to-face version of an introductory course on climate change. Both versions were taught by a single instructor, thus, minimizing instructor bias. Women, seniors, English language learners, and humanities majors disproportionately chose to enroll in the online version because of its ease of scheduling and accessibility. After correcting for performance-gaps among different demographic groups, the COVID-19 pandemic had no significant effect on online student performance and students in the online version scored 2% lower (on a scale of 0-100) than those in the face-to-face version, a penalty that may be a reasonable tradeoff for the ease of scheduling and accessibility that these students desire.

Aspects of online college science courses that alleviate and exacerbate undergraduate depression

Depression is a top mental health concern among college students, yet there is a lack of research exploring how online college science courses can exacerbate or alleviate their depression. We surveyed 2,175 undergraduates at a large research-intensive institution about the severity of their depression in large-enrollment online science courses. The survey also explored aspects of online science courses that exacerbate or alleviate depression and we used regression analyses to assess whether demographics predicted responses. Over 50% of undergraduates reported experiencing depression and LGBTQ+ students, financially unstable students, and lower division students were more likely to experience severe rather than mild depression compared to their counterparts. Students reported difficulty building relationships and struggling to perform well online as aspects of online science courses that exacerbated their depression and the flexible nature of online courses and caring instructors as aspects of online courses that alleviated their depression. This study provides insight into how instructors can create more inclusive online learning environments for students with depression.

The Experiences of Undergraduates with Depression in Online Science Learning Environments

Depression is one of the top mental health concerns among undergraduates and disproportionately affects students who are underrepresented in science. As such, understanding how emerging science learning environments, such as online science courses, affect students with depression is integral to creating a more inclusive scientific community. In this exploratory study, we interviewed 24 undergraduates with depression who were pursuing an online BS degree in biological sciences at a research-intensive institution. We assessed how students perceived depression affected their learning, and in turn, how online science courses affected their depression. Using a hybrid approach of deductive and inductive coding, we found that students reported depression negatively affected an array of cognitive domains when learning science online, including students' effort, focus, and time management. Students reported that the fast pace of online courses, the lack of needing to show up to a class in person, and difficulty developing relationships with other students commonly exacerbated their depression. Conversely, the flexibility of completing course work when and where students wanted, developing a relationship with the instructor, and the ease of having questions answered online positively affected students' depression. This study provides insight into ways to create inclusive online learning environments for students with depression.

Anatomical self-efficacy of undergraduate students improves during a fully online biology course with at-home dissections

Student enrollments in online college courses have grown steadily over the past decade, and college administrators expect this trend to continue or accelerate. Despite the growing popularity of online education, one major critique in the sciences is that students are not trained in the hands-on skills they may need for the workforce, graduate school, or professional school. For example, the Association of American Medical Colleges has recommended that medical schools evaluate applicants on their motor skills and observation skills, yet many online biology programs do not offer opportunities for students to develop these skills. In on-campus biology programs, students commonly develop these skills through hands-on animal dissections, but educators have struggled with how to teach dissections in an online environment. We designed a fully online undergraduate biology course that includes at-home, hands-on dissections of eight vertebrate specimens. Over three course offerings, we evaluated changes in four student outcomes: anatomical self-efficacy, confidence in laboratory skills, perceptions of support, and concerns about dissections. Here, we describe how we implemented at-home dissections in the online course and show that students taking the course gained anatomical self-efficacy and confidence in multiple laboratory skills. Based on open-ended responses, the students perceived that their experiences with the at-home dissections facilitated these gains. These results demonstrate that at-home, hands-on laboratories are a viable approach for teaching practical skills to students in fully online courses. We encourage science instructors to introduce at-home laboratories into their online courses, and we provide recommendations for instructors interested in implementing at-home laboratories.

Aspects of Large-Enrollment Online College Science Courses That Exacerbate and Alleviate Student Anxiety

Anxiety is the top mental health concern for undergraduates. While researchers have identified ways that in-person science courses can affect anxiety, little is known about how online science courses affect anxiety. In this study, 2111 undergraduates at a large research-intensive institution completed survey questions about their anxiety in large-enrollment online science courses. Specifically, we assessed students' anxiety in the context of online science courses and asked what aspects of online science courses increase and decrease their anxiety. Students also identified what instructors can do to lessen anxiety in online classrooms. We used open coding and logistic regression to analyze student responses. More than 50% of students reported at least moderate anxiety in the context of online college science courses. Students commonly reported that the potential for personal technology issues (69.8%) and proctored exams (68.0%) increased their anxiety, while being able to access content at a later time (79.0%) and attending class from where they want (74.2%) decreased their anxiety. The most common ways that students suggested that instructors could decrease student anxiety is to increase test-taking flexibility (25.0%) and be understanding (23.1%). This study provides insight into how instructors can create more inclusive online learning environments for students with anxiety.

COVID-19 and Undergraduates with Disabilities: Challenges Resulting from the Rapid Transition to Online Course Delivery for Students with Disabilities in Undergraduate STEM at Large-Enrollment Institutions

The COVID-19 pandemic caused nearly all colleges and universities to transition in-person courses to an online format. In this study, we explored how the rapid transition to online instruction during the COVID-19 pandemic affected students with disabilities. We interviewed 66 science, technology, engineering, and math (STEM) undergraduates with disabilities at seven large-enrollment institutions during Spring 2020. We probed to what extent students were able to access their existing accommodations, to what extent the online environment required novel accommodations, and what factors prevented students from being properly accommodated in STEM courses. Using inductive coding, we identified that students were unable to access previously established accommodations, such as reduced-distraction testing and note-takers. We also found that the online learning environment presented novel challenges for students with disabilities that may have been lessened with the implementation of accommodations. Finally, we found that instructors making decisions about what accommodations were appropriate for students and disability resource centers neglecting to contact students after the transition to online instruction prevented students from receiving the accommodations that they required in STEM courses during the COVID-19 pandemic. This study illuminates current gaps in the support of students with disabilities and pinpoints ways to make online STEM learning environments more inclusive for students with disabilities.
