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.

INTRODUCTION

Anxiety, defined as an unpleasant emotional state characterized by subjective feelings of tension, apprehension, and worry (Spielberger, 2013), is the top reported mental health concern for undergraduates (Center for Collegiate Mental Health, 2021). The rate of undergraduate anxiety continues to rise (American College Health Association, 2019; Center for Collegiate Mental Health, 2021), and improving student mental health is of interest to colleges and universities (National Council on Disability, 2017; Hsu and Goldsmith, 2021). While low levels of anxiety have been shown to be motivating for students, high anxiety levels are reported to be exclusively detrimental (Deshpande and Kawane, 1982; Teigen, 1994). Individuals who experience anxiety can experience symptoms such as feelings of nervousness or tiredness, sweating and trembling, and trouble concentrating, which can lead to insomnia, social isolation, or issues performing in school (Mayo Clinic, 2021).

High levels of student anxiety have been shown to negatively affect student motivation and performance in college (McKeachie, 1951; Culler and Holahan, 1980; Fletcher and Carter, 2010; Vitasari ; England , 2019; Hood ). Student anxiety may be particularly detrimental in science courses owing to the rigor and difficulty of the material (Udo ; Mallow, 2006) and the competitive, chilly and sometimes hostile environments (Seymour and Hewitt, 1997; Brainard and Carlin, 1998; Wyer ). Studies have shown that students who report experiencing anxiety in college science courses perceive difficulty thinking through science problems and articulating their thoughts about science (Cooper ; Cooper and Brownell, 2020; Downing ). Further, anxiety in college science courses has been negatively correlated with both students’ performance (England , 2019; Hood ) and plans to persist in biology degree programs (England ).

Recent research has aimed to identify specific aspects of college science courses that affect student anxiety in an effort to identify potential targets for interventions that could make classrooms more inclusive for students. For example, studies have examined student anxiety as it relates to students asking and answering questions in large-enrollment courses (Nadile ), as well as how active learning, defined as having students engage in their learning through activities and discussion in class (Freeman ), affects student anxiety at research-intensive (R1) institutions (England ; Cooper ; Adkins-Jablonsky ) and community colleges (Downing ; Hood ). Collectively, these studies have identified that active-learning courses have the potential to increase students’ anxiety because they often increase social interactions among students and between students and instructors. Particularly, fear of negative evaluation, or a student’s sense of dread associated with being unfavorably evaluated while participating in a social situation (Watson and Friend, 1969; Weeks ), is the primary factor underlying many students’ anxiety in college science courses (Cooper ; Cooper and Brownell, 2020; Downing ). Importantly, a limitation of the extant research examining the relationship between student anxiety and college science courses is that most studies have focused exclusively on the experiences of students taking in-person courses.

As online learning opportunities increase across higher education institutions, there is a greater need for research examining the relationship between student anxiety and online learning. In the past two decades, academic institutions and students have made great shifts toward online learning experiences and are capitalizing on the flexibility and accessibility that online courses offer (Allen and Seaman, 2013). The proportion of undergraduate students taking online courses quadrupled in the period from 2000 to 2012 (Protopsaltis and Baum, 2019); as of 2019, more than 400 universities in the United States offered solely online bachelor’s degrees, including degrees in the sciences (McCarthy, 2019). Additionally, the COVID-19 pandemic accelerated the transition to online learning for higher education institutions in March of 2020, as many institutions opted to transition their in-person courses online (“Tracking the Coronavirus at U.S. Colleges and Universities,” 2020). As of Fall 2020, 75% of American institutions continued to deliver courses either completely or partially online (“Here’s Our List of Colleges’ Reopening Models,” 2020). Given the magnitude of students who are currently engaging in online courses and the likelihood of online courses becoming common among institutions of higher education, identifying factors that exacerbate student anxiety online and mitigating anxiety to maximize student learning are of chief concern.

Studies of online courses before the pandemic provide some insight into what factors might affect student anxiety, although we know of no studies specifically targeting online college science courses. For example, a study of students in communication and information technologies found that 32% of students experienced an increase in anxiety when asked to collaborate with other students online because of the fear of being judged and having to rely on others (Hilliard ). However, another study of students enrolled in a variety of online courses found that, on average, interactions in the course such as student–student and student–instructor interactions decreased anxiety in the virtual learning environment (Idemudia and Negash, 2012). In a study of students enrolled in online courses across multiple disciplines, researchers found that students’ anxiety decreased as their prior experience in online courses and sense of preparedness increased. Finally, students in an online graduate program reported increased anxiety at the beginning of courses, particularly when the course content was unavailable before the beginning of class and when the schedule, including due dates and exam dates, was not posted (Conrad, 2002). Additionally, how instructors choose to teach has been shown to affect student anxiety in in-person courses and likely affects student anxiety in online courses as well. For example, instructors who make an effort to reassign students to the same online small groups may help students establish relationships with each other, decreasing their anxiety (Cooper ; Downing ). Additionally, giving students appropriate time to think through science problems and even share their thoughts within a small group may decrease students’ anxiety, but randomly calling on students to share their responses in front of the whole class would likely increase their anxiety (Downing ; Cooper ). While there are no prior studies directly examining student anxiety in online science courses, this previous work collectively provides some insights into what aspects of online courses may affect student anxiety in the context of college science.

Addressing anxiety in online science courses may disproportionately benefit students in certain demographic groups who are underrepresented and/or underserved in the sciences. For example, studies have shown individuals in particular demographic groups are more likely to report anxiety than their counterparts. Demographic groups who commonly report higher anxiety include women compared with men (Bayram and Bilgel, 2008; Bryant ; Abdous, 2019; England ; Misra and McKean, 2000), persons excluded because of their ethnicity or race (PEERs) compared with white students (Eckberg, 2015; England ; Soria and Horgos, 2021), students with disabilities compared with students without disabilities (Hoy ; Coduti ), LGBTQ+ students compared with non-LGBTQ+ students (Oswalt and Wyatt, 2011; Grant ), first-generation college students compared with continuing-generation students (Gaudier-Diaz ), students with depression compared with those without depression (Eisenberg ; Mahmoud ), and students with financially unstable homes compared with those with financially stable homes (Eisenberg ). A student’s year in the undergraduate program may also affect anxiety levels; one study found that upperclassmen are more anxious than lowerclassmen (Beiter ), but others have found that students in their first or second year have higher anxiety than their peers (Rawson ; Bayram and Bilgel, 2008; England ). These data suggest that student demographics may be important predictors of student anxiety, but it is unknown whether students from different demographic groups experience differing levels of anxiety in the specific context of online science courses.

In this study, we aimed to examine the anxiety of students enrolled in an in-person degree program who were taking science courses online because of the COVID-19 pandemic. Our research questions are as follows:

To what extent do undergraduates experience anxiety in the context of large-enrollment online college science courses, and do student demographics predict differences in anxiety levels?

To what extent and why do students traditionally enrolled in an in-person degree program experience different levels of anxiety in large-enrollment online science courses compared with in-person college science courses? Do demographics predict whether students are more likely to experience higher anxiety online or in person?

What factors increase students’ anxiety in large-enrollment online college science courses? Do student demographics predict what increases students’ anxiety?

What factors decrease students’ anxiety in large-enrollment online college science courses? Do student demographics predict what decreases students’ anxiety?

In students’ opinions, what can instructors do to decrease student anxiety in large-enrollment online college science courses?

METHODS

The study was done with an approved Institutional Review Board protocol no. 13434 from Arizona State University.

This research project was conducted as part of a biology education course-based research experience, or CRE (also commonly known as a course-based undergraduate research experience or CURE; Auchincloss ), in which 13 students along with the instructor conducted a biology education research project in the context of a course with the intent to publish their findings (Cooper and Brownell, 2018). Both life sciences undergraduate and graduate students were enrolled in the CRE, which was taught entirely online by K.M.C. during the Spring 2021 semester. The course was backward designed to develop students’ scientific thinking, writing, information literacy, question formulation, study design, data analysis, interpretation, and evaluation skills (Cooper ; Clemmons ; Turner ). Together with the instructor, the students were responsible for the development of the research questions and survey tool, collecting and analyzing the data, and writing the manuscript. Henceforth, the students in the CRE are referred to as “CRE researchers” to distinguish them from undergraduates who served as participants in our study.

Study Context

For this study, we aimed to survey undergraduates who were enrolled in an in-person degree program who were completing large-enrollment science courses online due to the COVID-19 pandemic. As such, we conducted our study at a large R1 institution in the U.S. Southwest where the majority of large-enrollment science courses for the in-person program were offered exclusively online in Summer 2020, Fall 2020, and Spring 2021. We chose to focus the study on large-enrollment courses because class size may affect student anxiety (Cooper ; England ; Downing ) and because these courses were most likely to be offered exclusively online. The COVID-19 pandemic provided a unique situation to answer our research questions; compared with prior semesters at the institution where this research was conducted, thousands more students were engaging in online science coursework and could provide insight into aspects of online courses that affect anxiety. However, we acknowledge that this study was conducted during the COVID-19 pandemic, a time of racial unrest and racially driven hate crimes, the Black Lives Matter movement, and months after U.S. political tensions resulted in a riot at the U.S. Capitol Building, all of which may have affected student anxiety (Chou ; Kecojevic ; Kibbey ; Ni ; Lee ). As such, we intentionally directed students to think about their anxiety in the specific context of their online science courses as opposed to their anxiety more generally.

Survey Development

To answer our research questions, we developed a survey that was distributed via Qualtrics. Thirteen CRE researchers reviewed the survey and recommended modifications using criteria to assess all questions (e.g., Is this question grammatically correct? Is the meaning of this question clear?; Bowden ). After revising the survey, five CRE researchers conducted think-aloud interviews with undergraduates who were taking online science courses to establish cognitive validity of the survey by checking to see whether students understood what each question was asking (Trenor ). The survey was iteratively revised based on each student’s feedback. The survey was then circulated among three biology education researchers who were not directly involved with this project, one of whom is an expert on anxiety in the context of biology courses. The survey was revised again based on their recommendations. Thirteen CRE researchers reviewed the survey a final time before it was distributed to students. A copy of the survey questions that were analyzed for this study is provided in the Supplemental Material.

Survey Distribution

We emailed all instructors teaching life sciences courses at the R1 institution (n = 127) in March of 2021 and asked if they would be willing to distribute our survey about students’ mental health to students in their online science courses. Of the instructors contacted, 38 (29.9%) agreed to send the survey out to their students in their course(s) in exchange for extra credit or in exchange for the student to enter a raffle to win one of two $100 gift cards. Multiple instructors distributed the survey in more than one of their courses. Based on course enrollment numbers at the time, we estimate that the survey was sent to a total of ∼4450 life sciences students. We chose to recruit from the life sciences department because it is the largest in the natural sciences and because students in these courses were likely to be enrolled in multiple online science courses at once. In total, 2175 students (48.8% of students who were sent the survey) recruited from 55 unique life sciences courses completed the survey. The number of students recruited from specific course types (e.g., neurobiology, microbiology) are reported in the Supplemental Material.

Survey Questions and Analysis

Screening Questions and Demographics.

The first question on the survey asked students how many large-enrollment online college science courses they had enrolled in. We defined large-enrollment as a course of 100 or more students (Nadile ) and science courses to be any biology, chemistry, geosciences, or physics courses. Only students who had completed at least one large-enrollment online college science course were included in the analyses to answer our research questions. Additionally, we asked students how many in-person large-enrollment college science courses they had enrolled in. Only students who had enrolled in at least one large-enrollment online and at least one large-enrollment in-person course were included in the analyses comparing student experiences online and in person. At the end of the survey, students were asked a series of demographic questions. A copy of the survey questions analyzed in this study can be found in the Supplemental Material. The remaining survey questions are described in the following sections in line with the respective research questions they were analyzed to answer.

RQ 1: To What Extent Do Undergraduates Experience Anxiety in the Context of Large-Enrollment Online College Science Courses, and Do Student Demographics Predict Differences in Anxiety Levels?

To investigate the extent to which undergraduates experience anxiety in the context of online college science courses, we asked students to indicate their average level of anxiety in the context of large-enrollment online college science courses on a Likert scale: 1) little to no anxiety, 2) mild anxiety, 3) moderate anxiety, or 4) severe anxiety. We calculated the percent of students who selected each anxiety level. Then, we used multinomial logistic regression to determine to what extent students’ demographics predict differences in anxiety levels. Multinomial logistic regression is an approach for modeling the relationship between more than two categorically distributed dependent variables, in this case whether a student reported experiencing 1) little to no or mild anxiety, 2) moderate anxiety, or 3) severe anxiety in the context of large-enrollment online college science courses. We decided to combine little to no anxiety and mild anxiety into one category to limit our dependent variable to a total of three distinct options, because we were most interested in whether there were differences in demographics among students with lower anxiety (none, little, or mild), moderate anxiety, and severe anxiety. We chose which predictors to include in our model based on prior literature suggesting that particular demographics may affect student anxiety. Our predictors included gender (man/woman), race/ethnicity (white, Asian, Black, Latinx), college generation status (first generation/continuing generation), LGBTQ+ status (yes/no), financial stability while taking online science courses (financially stable, not financially stable, sometimes financially stable), science, technology, engineering, and math (STEM) major (yes/no), grade point average (GPA; self-reported using a four-point scale), history of depression (yes/no), year in school (lowerclassmen/upperclassmen), and experience in online science courses (less experienced/more experienced). Model: severity of anxiety (low/moderate/severe) ∼ gender + race/ethnicity + college generation status + LGBTQ+ status + financial stability + STEM major + GPA + depression + year in school + experience online. We recognize that not all individuals identify as gender binary (man or woman; Cooper ), but there were too few students who identified as a gender other than man or woman to create a third category for analyses. Additionally, we excluded students who identified as American Indian or Alaska Native, Pacific Islander, or as a race not listed on the survey from the analyses owing to low sample sizes. We combined first- and second-year undergraduate students into a single category, “lowerclassmen,” and students who were in their third year or later of their undergraduate careers into “upperclassmen.” We considered students who reported taking one to three large-enrollment online college science courses as having “less experience online” and students who had taken four or more large-enrollment online college science courses as having “more experience online.” We also grouped students into science, technology, engineering, and math (STEM) majors and non-STEM majors, because we perceived that students with STEM majors may have different experiences in online science courses than students in non-STEM majors (Cotner ; Michaluk ).

RQ 2: To What Extent and Why Do Students Traditionally Enrolled in an In-Person Degree Program Experience Different Levels of Anxiety in Large-Enrollment Online Science Courses Compared with In-Person College Science Courses? Do Demographics Predict Whether Students Are More Likely to Experience Higher Anxiety Online or In Person?

We asked all students who had completed at least one large-enrollment online and one large-enrollment in-person college science course to compare their average level of anxiety between the two modalities; students could respond that, on average, their anxiety was higher, lower, or the same in online courses compared with in-person courses. Afterward, students were provided an open-ended question asking them to explain why they perceived their anxiety to be higher, lower, or the same in online courses compared with in-person courses.

We calculated the percent of students that reported higher, lower, or the same amount of anxiety in online courses compared with in-person courses. We used open-coding methods (Saldaña, 2015) to identify why students perceived their anxiety to be higher, lower, or the same in online courses. Two CRE researchers (T.F.M. and T.D.W.) reviewed a randomly selected set of 40 student responses explaining why their anxiety was higher in large-enrollment online college science courses compared with in-person courses and took detailed analytic notes to identify emerging themes (Birks and Mills, 2015). Then, the researchers convened, compared their notes, and developed a preliminary coding rubric. Together, they read through an additional 100 student responses to refine the rubric. The team of researchers then tested their coding rubric by reading through an additional 40 responses together and used constant comparison methods to verify that quotes within a category were similar to one another and not too different to warrant the creation of a new theme (Glesne and Peshkin, 1992). Once the final rubric was established, the two CRE researchers used the rubric to code all student responses to consensus (Stemler, 2004). Each theme in the rubric is mutually exclusive; that is, an excerpt of text could only be coded as one theme. However, students’ full responses often included multiple themes.

These methods were repeated to identify common themes as to why students reported lower anxiety in online courses compared with in-person courses (data analyzed by CRE researchers D.B. and K.M.W.) and why students reported experiencing the same amount of anxiety in both environments (data analyzed by CRE researchers E.M.N. and C.T.C.). The final coding rubrics for each question are included in the Supplemental Material.

We used multinomial logistic regression to assess whether student demographics predicted whether a student reported that, compared with in-person courses they experienced 1) higher anxiety in online courses, 2) the same amount of anxiety in online courses, or 3) lower anxiety in online courses. Model: anxiety online compared with in person (higher/same/lower) ∼ gender + race/ethnicity + college generation status + LGBTQ+ status + financial stability + STEM major + GPA + depression + year in school + experience online.

RQ3 and RQ4: What Factors Increase/Decrease Students’ Anxiety in Large-Enrollment College Science Courses? Do Student Demographics Predict What Increases/Decreases Students’ Anxiety?

Students were given two open-ended questions and asked to list as many aspects of large-enrollment online science courses they could think of that increased and decreased their anxiety. After students completed the open-ended questions, they were presented with two closed-ended questions asking them to 1) select from a list of 16 aspects of online college science courses that increased their anxiety (e.g., the potential for personal technology issues, difficulty getting help from other students in class) and 2) to select from a list of 18 aspects of online college science courses that decreased their anxiety (e.g., being able to access content at a later time, not having to be on camera). For each list, students were asked to select as many aspects as applied to them. Aspects listed in the closed-ended questions were developed by reviewing the literature for aspects of online courses that may affect student anxiety (e.g., Conrad, 2002; Stiller and Köster, 2016) and by identifying common experiences from the undergraduate student researchers in the CRE who were all originally enrolled in an in-person degree program but taking science courses online (see the Positionality Statement to learn more about the CRE student researchers). We chose to identify the factors that affect student anxiety using both open- and closed-ended questions, because the open-ended questions do not confine what students can report and the closed-ended questions allow students to consider their experiences from a more holistic perspective. Additionally, the closed-ended questions could be used as outcome variables in models examining potential demographic differences. We compared students’ open-ended responses with the closed-ended responses and found that closed-ended responses were generally reflective of students’ open-ended responses. The specific analyses are described below.

Open-coding methods were used to identify themes that increased students’ feelings of anxiety from open-ended responses (Saldaña, 2015). Two CRE researchers (B.A.E. and M.T.) independently reviewed a randomly selected set of 40 student responses, took note of any repeated emergent themes, and developed a preliminary coding rubric (Birks and Mills, 2015). Together they read through an additional 100 student responses to refine the rubric using constant comparison methods (Glesne and Peshkin, 1992) and tested its efficacy on another 40 responses. Once the final rubric was established, the pair of researchers used the rubric to code a subset of 317 responses (15% of total responses) to consensus (Stemler, 2004). See the Supplemental Material for a copy of the coding rubric. Coding approximately 20% of qualitative data in large sample sets (in this case, 140 students to test the efficacy of the rubric and the additional 317 responses total more than 20% of all responses) is considered enough to be representative of the entire data set (Syed and Nelson, 2015).

To determine the relationship between the predetermined closed-ended responses and students’ open-ended response, the two CRE researchers calculated the percent of students who selected each closed-ended response and compared them with the themes that emerged from students’ responses to the open-ended questions. Because the open-ended responses generally reflect the closed-ended responses, we only report the analyses of the closed-ended responses within the article. The categories that emerged from the open-ended responses and the percent of students who reported each category are reported in the Supplemental Material.

We used binary logistic regression, an approach for modeling the relationship between two or more independent variables, or predictors, and a dependent variable that is dichotomous in nature, to test whether there were demographic differences among students who selected each factor of online science courses that increased their anxiety (model: selected factor (yes/no) ∼ gender + race/ethnicity + college generation status + LGBTQ+ status + financial stability + STEM major + GPA + depression + year in school + experience online + anxiety).

Another pair of CRE researchers (J.G.W. and C.L.) repeated the process described previously with factors that decreased student anxiety. The final coding rubric for the open-ended question about what decreases students’ anxiety and the percent of students who reported each theme is included in the Supplemental Material. The CRE researchers determined that the open-ended responses generally reflected the closed-ended responses. As such, we only report the analyses of the closed-ended responses within the article.

RQ5: In Students’ Opinions, What Can Instructors Do to Decrease Student Anxiety in Large-Enrollment Online College Science Courses?

To identify specific ways to help reduce student anxiety in online classrooms, we used an open-ended question to give students the opportunity to suggest what they believe instructors of large-enrollment online science courses could do to decrease student anxiety. Starting with a randomly selected set of 40 student responses, two CRE researchers (C.V. and M.L.W.) individually reviewed and wrote down detailed analytic notes on what they perceived as common themes emerging from student responses (Birks and Mills, 2015). Then, the two CRE researchers convened and compared their notes describing the themes they had identified to develop a preliminary coding rubric. Together, they then read through an additional 100 student responses to locate and address any discrepancies with the initial coding rubric. The researchers used constant comparison methods to verify that students’ quotes were similar enough to fall within the same category and did not differ enough to warrant a new category (Glesne and Peshkin, 1992). The team of researchers then tested their coding rubric by reading through an additional 40 responses together. Students’ full responses to the question often included multiple themes, but each phrase within a response was only coded once. Once the final rubric was established, the two researchers used the rubric to code a representative sample of the data (30%, n = 634 student responses) to consensus (Stemler, 2004). The researchers reached saturation after coding approximately 150 student responses, indicating that no additional new themes were emerging from the data set (Morse ).

Reporting of Results

We recognize that the significance of a result from any statistical test is continuous rather than dichotomous based on the specific p value (Wasserstein ). However, we report select results by the criterion of p ≤ 0.05 throughout the Results section for simplicity. We acknowledge that test results with p values greater than 0.05 can still be scientifically meaningful, and therefore we report out all results of statistical tests in the Supplemental Material for the reader’s further interpretation. Additionally, we describe our results using language such as “women had 1.2× higher odds than men of selecting a particular factor.” The number, “1.2” in this case, is the natural exponential of the estimated coefficient for the explanatory variable, in this case “women” versus “men,” in the logistic regression model to predict whether the student will select a particular factor. This number is also called the “odds ratio,” which is a standardized effect size statistic in logistic regression (Deeks, 1998; Agresti and Franklin, 2012). For all themes that emerged from student open-ended responses, we decided to include those reported by at least 10% of students. However, for student recommendations about how instructors could decrease anxiety, we highlight themes reported by at least 5% of students, as there were a substantial number of themes between 5% and 10% that we felt would be of interest to the reader.

Positionality Statement

The research team collectively identify as men or women and represent multiple races and ethnicities including Asian, American Indian, Black, Creole, Latinx, and white. About half of the researchers are the first in their families to attend college. Some researchers identify as struggling with anxiety or an anxiety disorder and some do not. At the time the research was conducted, nine CRE researchers were undergraduates and four were graduate students. We used our diverse identities and experiences to try and counteract implicit biases in the way we collected, analyzed, and evaluated the data for this research (Intemann, 2009).

RESULTS

Participants

A total of 2175 students completed the survey, and 97.1% of those students (n = 2111) had completed at least one large-enrollment online college science course. Eighty eight percent of students reported taking at least one synchronous online science course, and 55.3% reported taking at least one asynchronous online science course. Students were primarily women (66.6%), white (48.1%), continuing-generation college students (58.5%), and in their first or second year of college (58.6%). Additionally, 40.6% of students reported that they did not consider themselves financially stable or only considered themselves financially stable sometimes while completing online college science courses. Nearly 17% of students identified as a member of the LGBTQ+ community, and 53.8% of students identified as having depression. Student demographics are summarized in Table 1.

Students were asked whether they considered themselves financially stable (e.g., had enough money for necessities such as groceries and rent) during the time they have been enrolled in online college science courses.

Students were asked whether they identify as having currently or previously struggled with depression or a depressive disorder.

Finding 1. Students Most Commonly Reported Moderate Anxiety in the Context of Large-Enrollment Online Science Courses and Women, Students Who Are Financially Unstable, and Those with Depression Experience Higher Anxiety Than Their Counterparts

Of the 2111 survey participants, 19.7% reported experiencing little to no anxiety, 29.2% reported mild anxiety, 37.2% reported moderate anxiety, and 13.9% reported experiencing severe anxiety in their large-enrollment online college science courses (Figure 1).

FIGURE 1.

Students’ average level of anxiety in online college science courses (n = 2111).

Comparing students who experienced no to mild anxiety with those who experienced moderate and severe anxiety, we identified significant demographic differences between groups. Women, students who were financially unstable, and students with depression were more likely than men, students who were financially stable, and students without depression to report both moderate and severe anxiety. Additionally, students with more experience in online courses were more likely to report moderate anxiety compared with students with less experience, and STEM majors were more likely to report severe anxiety compared with non-STEM majors. The results of the multinomial regression are summarized in Figure 2 and reported in full in the Supplemental Material.

For each group of interest, indicated in parentheses, the odds ratio indicates the extent to which students with that identity disproportionately reported moderate or severe anxiety compared with the reference group. Blue numbers indicate odds ratios greater than or equal to 1 and red numbers indicate odds ratios less than 1 (i.e., these individuals were less likely to exhibit moderate or severe anxiety compared with the reference group).

Finding 2. Students Were More Likely to Report That They Have Higher Anxiety in Their Large-Enrollment Online College Science Courses Compared with Large-Enrollment In-Person College Science Courses

Of the 893 students who reported having enrolled in at least one large-enrollment online science course and one large-enrollment in-person science course, 39.9% of students reported that they have higher anxiety in online science courses compared with in-person science courses. Conversely, 27.0% of students reported that they have lower anxiety in online science courses compared with in-person science courses, and 33.1% reported experiencing the same amount of anxiety in each modality. We identified a number of significant demographic differences in students’ anxiety levels in online versus in-person science courses. Lowerclassmen had 1.7 times higher odds than upperclassmen of reporting higher anxiety online (compared with lower anxiety online), and students with depression had 2.0 times higher odds than students without depression of reporting higher anxiety online (compared with reporting the same anxiety online and in person). No other demographic differences predicted whether students reported differing levels of anxiety in large-enrollment online science courses compared with in-person science courses. Full results of the logistic regression assessing demographic differences are reported in the Supplemental Material.

Of the students who reported experiencing higher anxiety in online courses, 99.4% of students responded to the open-ended question asking them to explain why. Of those respondents, students most commonly reported that they perceived learning to be more difficult online (55.7%), often describing that it was hard for them to learn independently, stay engaged, or teach themselves online. Students also described that their anxiety is higher online, because they find it more difficult to be organized, self-paced, or keep track of due dates online compared with in person (21.2%). Finally, students commonly reported that making connections with students is more difficult online (21.2%). The most common reasons reported by at least 10% of students as to why their anxiety is higher in online science courses compared with in-person science courses are reported with example student responses in Table 2.

TABLE 2.

The most common reasons why students report higher anxiety in large-enrollment college science courses compared with in-person coursesa

Category	Category description	% (n) N = 354	Example student response	Example student response
Learning is more difficult online.	Student describes their anxiety is higher in online courses compared with in person because it is more difficult to pay attention and stay engaged or focused.	55.7% (197)	Student 181: “I just feel like I have to work 100× harder to understand the material in an online course. A lot more goes into teaching myself the material because I don’t get to sit in a lecture hall and absorb information by being in a physical academic setting.”	Student 275: “It’s extremely difficult to stay focused when there is just less engagement overall. I feel like a failure because I’m just not absorbing knowledge.”
It is more difficult to stay organized and keep up with online coursework.	Student describes their anxiety is higher in online courses compared with in person because it is more difficult to stay on top of or ahead of assignments and easier to fall behind or procrastinate.	21.2% (75)	Student 951: “It is harder for me to stay on track and keep myself accountable when all of my learning is happening in an environment that my brain associates with relaxation and play (childhood bedroom).”	Student 97: “I’m more uncertain when due dates are [in my online courses]. There’s this feeling of constantly needing to check [the online course platform] and my email to make sure I’m not missing anything.”
Making connections with students is more difficult.	Student describes their anxiety is higher in online courses compared with in person because it is harder to connect and interact with students or form study groups online.	21.2% (75)	Student 964: “It comforts me to know that there are many students in my classes where we can interact in person. Many times, online, people are nervous to unmute themselves and there are no opportunities to talk and meet classmates during online lectures.”	Student 885: “I am unable to engage with other people physically, which I would typically [do] in a classroom. That helps me share my ideas and discuss certain topics to [sic] my fellow classmates.”
Making connections with instructors is more difficult.	Student describes their anxiety is higher in online courses compared with in person because there are limited opportunities to connect with instructors online.	20.6% (73)	Student 1191: “There’s not an actual connection with the professors, it seems like they care less about their students’ well-being because they usually can’t see us.”	Student 1203: “There are fewer opportunities to interact with the professors [...] about vital information about the course material.”
There are distractions when trying to learn online.	Student describes their anxiety is higher in online courses compared with in person because there are more distractions, such as those at home or those caused by other students.	15.3% (54)	Student 1188: “I am always distracted when I’m at home.”	Student 191: “Since I live at home with two nieces, I get anxiety for not being able to concentrate.”
Taking exams is more difficult online.	Students describes their anxiety is higher in online courses compared with in person because of exam-related concerns, such as proctoring, scheduling, or the amount of time the exam is open.	14.1% (50)	Student 447: “Many of the online college science courses have rigorous proctoring systems that involve the camera and microphone being on whereas with in-person classes, the proctoring is less intense (for example, the online proctoring says you cannot look anywhere other than the screen). Though I understand the purpose of proctored exams, it is very overwhelming because I am so afraid of being flagged for academic dishonesty just for looking down for a moment to think.”	Student 651: “Proctored exams give me so much anxiety because I’m so terrified that if my family members make noise I will be flagged or if my eyes are wandering because I am trying to remember an answer I will be flagged. I spend so much time putting in the work and feel like that would not be recognized due to such high anxiety of being watched behind a camera. It is so frustrating and increases my stress so much.”
There are greater workloads and higher expectations online.	Students describes their anxiety is higher in online courses compared with in person because they perceive there is an increased workload, higher expectations, or that online courses are at a faster pace compared with in-person courses.	11.3% (40)	Student 1086: “It feels like more material is required from you when the class is online because the professors can give you content that would ordinarily take too long in an in-person classroom. It feels like most professors have been giving more work now that classes are online and we ‘have more time.’”	Student 408: “The deadlines and workload for STEM classes online is [sic] unrealistic. Increasing the workload and deadlines and expecting students to continuously perform at an exceptional level despite shortening the amount of time to prepare and increasing the amount of work is highly unrealistic.”

Of the 356 students who reported having higher anxiety online compared with in person, 354 students answered the open-ended question about why their anxiety was higher in this environment. Themes reported by at least 10% of students are summarized. Additional themes reported by at least 5% of students are reported in the Supplemental Material.

Of the students who reported experiencing lower anxiety in large-enrollment online college science courses, 99.2% responded to the question asking them why this was the case. Of the respondents, students most commonly mentioned that they had lower anxiety online compared with in person because they were able to learn in a comfortable or familiar environment (39.7%), because they did not have to stress about physically getting to class (15.9%), and because they perceive the material is easier to follow or more readily available online compared with in person (15.9%). The most common reasons reported by at least 10% of students as to why students experience less anxiety in online science courses and example student responses are reported in Table 3.

Category	Category description	% (n) N = 239	Example student response	Example student response
The student can learn in a comfortable or familiar environment.	Student describes their anxiety is lower in online courses compared with in person because they are in a familiar and comfortable environment.	39.7% (95)	Student 214: “[My anxiety is lower in online science courses because] I am in my own space where I am the most comfortable, so I am less anxious.”	Student 1595: “I have less anxiety in online classes because I am attending them in the comfort of my own home.”
The student does not have to physically get to class.	Student describes their anxiety is lower in online courses compared with in person because time is not wasted commuting to, getting to, or walking to classes.	15.9% (38)	Student 239: “[In my online science courses], I don’t have anxiety about being late to class (as a student–athlete it was challenging to attend practices and then have to rush over to class on campus).”	Student 495: “I have lower anxiety because time management and scheduling are much easier [online]. Instead of having to walk to classes and be in person, I can work on homework in between classes and take notes more easily when classes are online.”
The material is easier to follow or more readily available online.	Student describes their anxiety is lower in online courses compared with in person because the material is easier to follow or more accessible through the recording of lectures.	15.9% (38)	Student 120: “I am not excessively worried about missing/not catching what the professor says during lecture, as all of the videos are posted and I can rewatch them at any time.”	Student 1264: “I can rewatch recorded lecture videos and pause them if I need to finish writing something else down.”
There are fewer social interactions online.	Student describes their anxiety is lower in online courses compared with in person because it requires fewer personal interactions and does not exacerbate social anxiety.	14.2% (34)	Student 282: “I have an anxiety disorder and social situations can tend to make me anxious. I feel like there are less [social situations] in an online class than in person classes [which lowers my anxiety in my online science courses].”	Student 1791: “I feel less anxiety not being in person because I don’t have to be face-to-face and actually interact with students or teachers.”
The student can be anonymous online.	Student describes their anxiety is lower in online courses compared with in person because you can be anonymous or do not have to show your face and can choose not to be heard.	10.9% (26)	Student 265: “[My anxiety is lower in online science courses, because] I don’t have to have my webcam on or speak if I don’t want to.”	Student 1349: “[My anxiety is lower in online science courses because] no one can see me and I feel more comfortable.”

Of the 241 students who reported having lower anxiety online compared with in person, 239 students answered the open-ended question about why their anxiety was higher in this environment. In the table, we highlight themes reported by at least 10% of students. Additional themes reported by at least 5% of students are reported in the Supplemental Material.

Of the students who reported experiencing the same amount of anxiety in online courses compared with in-person courses, 98.3% of students provided a response to the question asking them why they perceived their anxiety levels to be the same in both environments. More than half of students reported that they experienced the same amount of anxiety in online courses compared with in-person courses because the factors that affect their anxiety are present in both online and in-person courses (52.1%). For example, 20.3% of students said that anxiety is the same because the workload and assignments are similar in both environments, and 10.7% of students said that they approach online and in-person courses or exams in the same way, resulting in the same amount of anxiety (common subthemes are reported in the Supplemental Material). Students also reported that anxiety can be the same in both online and in-person courses because aspects of a course that differ online and in person affect their anxiety the same amount (23.4%); for example, some students report that large-enrollment online and in-person courses have different stressors that affect their anxiety levels similarly. Finally, students reported that anxiety can be the same in both online and in-person courses because of personal factors (19.7%). For example, students reported that they are generally nervous or anxious or generally have low anxiety. The three primary reasons why students reported the same levels of anxiety are reported in Table 4 with example student quotes.

TABLE 4.

The most common reasons why students report the same amount of anxiety in large-enrollment college science courses compared with in-person coursesa

Category	Category description	% (n) N = 290	Example student response	Example student response
Anxiety is the same for the same reasons in both online and in-person courses.	Student describes that their anxiety is the same both in person and online for the same reasons.	52.1% (151)	Student 597: “I feel the environment and the learning atmosphere are pretty similar.”	Student 939: “Mainly for me, the atmosphere remains genuinely the same both online and in person.”
Anxiety is the same for different reasons in both online and in-person courses.	Student describes that their anxiety is the same both in person and online but for different reasons. Also, student describes there are different pros and cons for in-person and online courses, but the pros and cons balance one another out.	23.4% (68)	Student 1249: “Online courses have different stressors compared with in-person classes, however, my overall anxiety levels are about the same for each.”	Student 496: “It’s more difficult doing classes online, but you can rewatch lectures and you have more time since you aren’t commuting so it balances out.”
Anxiety is the same for personal reasons in both online and in-person courses.	Student describes that their anxiety is the same both in person and online due to personal reasons, such as having generally high or low anxiety.	19.7% (57)	Student 211: “I am always anxious about everything.”	Student 742: “I have little to no anxiety in online courses or in-person courses.”

Of the 295 students who reported having the same amount of anxiety online compared with in person, 290 (98.3%) students answered the open-ended question about why their anxiety was the same online and in person. All subthemes describing the reasons students experience the same amount of anxiety in online and in-person courses are included in the Supplemental Material.

Finding 3: Students Most Commonly Reported That Technology Issues, Online Exams, and Difficulty Getting to Know Other Students Increased Their Anxiety in Large-Enrollment Online College Science Courses

The aspects that students most frequently selected as increasing their anxiety were the potential for technology issues (69.8%), the use of proctored online exams (68.0%), experiencing difficulty in getting to know other students in the class (67.2%), feeling worried about accidentally causing a disruption during class (66.8%), and needing to have their cameras on (63.9%). Analyses yielded a number of significant demographic differences with regard to who was most likely to select particular factors related to large-enrollment online science courses that increase students’ anxiety. All significant findings are reported in Table 5. The full result of each regression is reported in the Supplemental Material.

Finding 5: Participants Identified Multiple Ways That Instructors Can Decrease Student Anxiety in Large-Enrollment Online College Science Courses, Including Increasing Test-Taking Flexibility, Being Understanding, and Having an Organized Course

Analyzing student open-ended responses, we identified 10 ways that students commonly reported that instructors can alleviate anxiety in their courses. The most frequently reported suggestion for what instructors of large-enrollment online college science courses could do to decrease student anxiety was to increase test-taking flexibility (25.0%); participants specifically described allowing students to take non-proctored or open-note exams and removing time limits for exams. The second most frequently reported suggestion was for instructors to be flexible and understanding about students’ unique situations and their mental health (23.1%); students recommended that instructors demonstrate understanding by extending deadlines when needed or by not penalizing students when they experience technological issues. Nearly 15% of students recommended that instructors could reduce student anxiety by providing an organized course. Students specifically suggested providing a full schedule of assignments and their corresponding deadlines, setting clear class expectations, and providing easily accessible class resources (e.g., Zoom links). Students also recommended that instructors be available and try to develop student–instructor relationships (13.0%). Students highlighted that instructors could create more avenues for student–instructor communication, whether it be through emails, office hours, or sharing information to help students learn more about their instructors. Further, students also suggested that instructors should allow camera use to be optional (9.9%), provide additional study materials (8.7%), allow students to rewatch recorded lectures (8.5%), facilitate the development of relationships among students (7.3%), decrease the opportunities for group work (5.7%), and decrease the course workload or slow down instruction (5.5%). An additional 5.3% of students reported that they perceive their instructors are doing the best they can to accommodate students’ needs in their online course. All recommendations reported by at least 5% of students are recorded in Table 7 with example quotes.

DISCUSSION

In this study, we examined undergraduate student anxiety in the context of large-enrollment online college science courses, specifically, how student anxiety online compares with anxiety during in-person courses, what aspects of online science courses increase and decrease student anxiety, and what instructors can do to try and decrease student anxiety. We also probed whether student demographics predicted their anxiety levels and what aspects of large-enrollment online college science courses affected their anxiety. A summary of the main findings is presented in Figure 3.

Anxiety in Large-Enrollment Online Science Courses during the COVID-19 Pandemic

Of the 2111 students who were enrolled in at least one large-enrollment online science course, we found that a substantial number of students reported experiencing moderate (37.2%) and severe (13.9%) levels of anxiety. Women, financially unstable students, and those with depression were disproportionately more likely to report higher anxiety in the context of online science courses compared with men, financially stable students and those without depression, respectively. While women (Misra and McKean, 2000; Bayram and Bilgel, 2008), individuals who are financially unstable (Eisenberg ), and those with depression (Eisenberg ; Mahmoud ) have been found to have higher generalized anxiety than their counterparts, there is evidence that the online environment may further exacerbate or contribute to these gaps. For example, women generally report feeling more anxious about taking courses online compared with men (Saadé ), and grade disparities between men and women are greater in online STEM courses compared with in-person courses (Mead ). Additionally, studies show that online science coursework could present challenges for students with depression because of the difficulties students experience developing relationships with students and instructors online, the lack of a need to show up somewhere in person, and the self-paced nature of online courses (Gin ; Mohammed ). Online courses likely also present unique challenges for students who are not financially stable, including the need for high-speed Internet access and quiet workspaces (Venegas, 2007; Aguilar ). Working to decrease student anxiety in online science may be integral to promoting a more diverse and inclusive scientific community, given the underrepresentation of women, those coming from low-socioeconomic backgrounds, and individuals with disabilities (such as depression) in the sciences.

When students were asked if they perceived experiencing higher, lower, or the same anxiety as in-person courses, we found that students most commonly reported experiencing higher anxiety in their online science courses. Disproportionate numbers of students with depression and those with higher GPAs reported higher anxiety online. This finding is supported by previous literature suggesting that online courses can be more anxiety inducing than in-person courses (DeVaney, 2010; Stowell and Bennett, 2010). When asked to explain why learning online caused students higher anxiety compared with in person, students most commonly reported that they perceived learning to be more difficult online as well as it being more difficult for them to stay engaged and on top of their assignments. Students may be perceiving it is more difficult for them to learn and stay on top of their assignments because online learning is typically associated with high self-regulation (Kauffman, 2015) and self-discipline (Waschull, 2005; Gorbunovs ). However, it should be noted that, even though students generally perceive learning online to be more difficult, it is unclear whether students learn more in online or in-person courses (Biel and Brame, 2016). Out of the studies that have controlled for academic ability in addition to other predictive factors of performance, such as gender and race/ethnicity, two have shown no difference in student learning outcomes measured by grades between students enrolled in online and in-person courses (Peterson and Bond, 2004; Cavanaugh and Jacquemin, 2015), while one found that students received higher grades in in-person courses (Mead ). Yet notably, in a large-scale study of more than 25,000 student-course enrollments at the institution where our study was conducted, researchers found that when in-person students were enrolled in online courses during the COVID-19 pandemic (as they were in the current study), students perceived that they learned less in online courses, despite receiving higher grades (Supriya ). Regardless of whether students actually learn more in online versus in-person science courses, providing students with information about how to self-regulate and improve their motivation, and subsequently reduce their anxiety, may help them adjust to online learning.

We also acknowledge that, while students were asked specifically about their anxiety in the specific context of online college science courses, the COVID-19 pandemic, racial unrest and racially driven hate crimes, and political unrest likely contributed to many students’ emotions and evaluation of their experiences of online versus in-person courses (Chou ; Kecojevic ; Ni ).

Factors Associated with Online College Science Courses and the Disproportionate Impact They May Have on Students in Different Demographic Groups

In attempts to continue building a more inclusive and welcoming community for students of diverse backgrounds, it is important to identify whether specific aspects of online college science courses disproportionately affect particular demographic groups of students. In the following sections, we discuss what aspects of online education may disproportionately contribute to students’ anxiety based on their demographics.

Gender.

In our analyses, which controlled for anxiety level in online college science courses, women were more likely than men to select that their anxiety was impacted by many of the social aspects of online science courses. For example, we found that women were more likely than men to report that being on camera contributed to their anxiety. This may be partially explained by women being more consciously aware of their physical appearance (Choukas-Bradley ; Castelli and Sarvary, 2021), combined with the notion that negative appraisals related to physical characteristics have been correlated with lower self-evaluations of social competence (Gibson and Thomas, 1991). This may also explain why women were more likely to report that not having to use their cameras and the ability to conceal parts of their identity online decreased their anxiety. Further, women were more likely than men to report that the possibility of accidentally causing an unwanted disruption during class and the fear of being judged when participating online increased their anxiety. While studies have shown that fear of negative evaluation, or the sense of dread associated with being unfavorably evaluated while participating in a social situation, is a common factor underlying student anxiety in science classrooms (Cooper ; Cooper and Brownell, 2020; Downing ), this is the first quantitative study to suggest that fear of negative evaluation may disproportionately affect women. However, these findings relate to previous studies showing that women are disproportionately likely to have mindsets associated with achieving perfectionism (Davis ), yet also more likely to have a low academic self-concept or lower perceptions of their abilities in academic domains compared with men, even when they have equivalent GPAs (Cooper ). Additionally, we found that women were more likely than men to report that being in a breakout room with people they do not know or working with students who were disengaged heightened their anxiety. This may be because women put a greater emphasis on interpersonal ways of communication (McKeachie ), with a preference to work in proximity with colleagues to receive direct support (Lee and Robbins, 2000). Moreover, working with a friend has been shown to be a predictor of student comfort in group work in college biology courses, which in turn predicts students’ content mastery (Theobald ), and women students in particular perceive less value in group work when they do not have a friend in the group (Eddy ). As such, women were more likely than men to select pre-assigned student groups and to select that using informal discussion platforms in online science courses as factors that decreased their anxiety. These findings suggest that women are disproportionately impacted by some of the social aspects of online courses.

Race/Ethnicity.

Students’ race/ethnicity also predicted what factors increased and decreased their anxiety in large-enrollment online college science courses; particularly, notable differences emerged between Latinx and non-Latinx white students. Latinx students were more likely than white students to select that their anxiety was impacted by aspects of online science courses related to privacy. For example, we found that Latinx students were more likely than white students to report having the camera on and specifically the possibility of their surroundings embarrassing them while on camera as factors that increased their anxiety. One hypothesis for why this may be is that Latinx households are associated with high levels of family engagement (Telzer and Fuligni, 2009), where it may be possible that ongoing family presence can lead to potential unwanted disruption during class time. In fact, a recent study showed that underrepresented minority students (a group that included Latinx students) reported that they sometimes did not turn their camera on because they were concerned about others being seen behind them (Castelli and Sarvary, 2021). This may also explain why Latinx students were more likely than non-Latinx white students to report that proctored exams increase their anxiety, as students may be penalized for interruptions that may occur while taking an exam. We also found that Latinx students were more likely than white students to report having instructors that care about students’ concerns as a factor that decreases their anxiety, which echoes a study that demonstrated that Latinx students value instructors who interact with students in caring ways (Newcomer, 2018). Therefore, we hypothesize that the third most commonly reported student recommendation to decrease student anxiety, having instructors make an effort to connect with students, may be especially beneficial for Latinx students.

Students with Depression.

Following anxiety, depression is the second most commonly reported mental health concern among college students (Center for Collegiate Mental Health, 2021). As such, we were interested in how, if at all, students’ depression predicted what factors affected their anxiety. We found that students with depression were more likely to report that needing to be on camera for class and the potential for their surroundings to embarrass them while on camera increased their anxiety. Literature has shown that students with depression value maintaining anonymity (Levine ). One interview study of students with depression found that needing to be on camera during online course work can worsen students’ depression because they cannot hide when they are feeling sad or upset (Mohammed ), and undergraduates are often reluctant to reveal their depression to peers and mentors (Cooper ); the camera being on may be particularly detrimental when students are feeling sad or disengaged, making it harder for students to conceal their depression from others. Additionally, we found that students with depression were more likely than students without depression to report that being able to access content at a later time, having the flexibility of attending class where they want, and having assignments without deadlines decreased their anxiety. This may be because students with depression report difficulty focusing and staying motivated in academic environments (Orr, 2019; Cooper ; Gin ), which would make having access to content at any time helpful. Further, students with depression are prone to experiencing depressive episodes or periods of time when their depression is especially bad. During these times, it can be helpful for students to not have to leave their homes and to have the option of catching up on work at a later time (Judd ; Cooper ). Students in this study highlighted that to decrease anxiety instructors could be more understanding of students’ mental health concerns and more flexible, which may be particularly beneficial for students with depression.

LGBTQ+ Students.

Science fields and college science courses can be particularly unfriendly toward LGBTQ+ individuals (Bilimoria and Stewart, 2009; Cech and Waidzunas, 2011; Patridge ; Cooper and Brownell, 2016; Linley ; Cooper ). As such, it is not necessarily surprising that LGBTQ+ students were more likely than non-LGBTQ+ students to report that worrying about being judged increased their anxiety and that being able to conceal their identities online helped to alleviate their anxiety. Further, science faculty are known to hold less positive attitudes toward LGBTQ+ issues compared with faculty in other disciplines (Brown ), which may help explain why LGBTQ+ students were more likely than their peers to report that not having to contact instructors in person decreased their anxiety. As such, not requiring students to keep their cameras on and reducing or eliminating the need for required verbal participation in front of the whole class may not only reduce student anxiety (Castelli and Sarvary, 2021; Cooper ), but may be disproportionately helpful for LGBTQ+ students who do not feel safe or welcome in college science courses.

Student Suggestions for Instructors about How to Reduce Anxiety in Large-Enrollment Online Science Courses

Decreasing student anxiety can result in an increase in student motivation and performance (McKeachie, 1951; Culler and Holahan, 1980; Fletcher and Carter, 2010; Vitasari ; England , 2019; Hood ). Many of the strategies that students in this study identified to reduce anxiety in online college science courses are further supported by the literature and may provide instructors with effective ways of mitigating student anxiety. For example, test anxiety, defined as feelings of excessive worrying, nervousness, or irrelevant thinking during an assessment (Rasor and Rasor, 1998; Hancock, 2002; Chapell ), is common among undergraduates (Hashmat ), and students in this study highlight why online exams can be uniquely stressful due to proctoring software and technological challenges. Thus, eliciting student concerns about online exams and enacting changes to make exams less anxiety provoking may be important; studies have demonstrated that instructors who positively respond to students’ concerns in an online context result in academic improvement, feelings of gratitude toward the instructor, and feelings of “having a voice” (Sitzman, 2016). Additionally, students highlighted the importance of online science instructors being understanding and flexible. Caring instructors in online education can help students feel more comfortable and appreciated, despite the lack of physical contact and proximity to the instructor (Leners and Sitzman, 2006). In general, positive student–instructor relationships have been found to be significant contributors to student learning, satisfaction, and belonging (Sher, 2009; Cooper ) and to decrease student academic dishonesty (Stearns, 2001). Further, students requested that instructors provide organized online science courses. Organization has been lauded as an essential element of online courses (Simon, 2000), given that online students often need to plan their personal schedules around their courses (Savery, 2005). As such, keeping course content organized and providing detailed and inclusive syllabi (Gin ) allow students to plan ahead when necessary, especially because most online students have important commitments outside school, such as work or family obligations (Harris and Martin, 2012). As college science courses continue to be increasingly delivered to students via online platforms, we encourage instructors to consider how small changes such as increasing communication with students and explicitly encouraging students could be impactful in reducing student anxiety and improving students’ experiences in science courses.

Limitations

This study was conducted during the COVID-19 pandemic, when the science courses at this particular institution were being taught online. While this unique situation made this study possible, it also limits the generalizability of our findings. We made substantial effort to focus students’ attention on their online science courses when they answered questions on the survey about their anxiety; however, it is possible that their responses may have been affected by other circumstances related to the COVID-19 pandemic, including increased financial and emotional strain. As such, these results may not be generalizable to students’ experiences after the pandemic, and this work should be replicated after the pandemic is over. Additionally, this study was conducted at a large R1 institution and further research needs to examine whether the findings are generalizable to other institutional types. While we predict that some of the aspects of online courses that affect anxiety would be relevant in smaller courses of less than 100 students, participants in this study were asked to consider only large-enrollment science courses. Finally, this study relied on students’ self-reporting; while self-report is an accurate way to gauge anxiety levels (Spitzer ), students’ perceptions of what increases and decreases their anxiety could be tested in future studies by measuring student anxiety before and after specific interventions. Finally, we chose not to correct for multiple testing based on the guideline offered by Wickens and Keppel (2004, p. 113). Specifically, given that each of our research questions was a principal driver of the study, questions are best considered in isolation. Hence, we fixed each test’s per-comparison rate at α = 0.05, and no other adjustments were made.

Conclusion

In this study, we explored student anxiety in the context of large-enrollment online college science courses and found that students most commonly reported moderate levels of anxiety, and women, students who were not financially stable, and students with depression were significantly more likely to report higher levels of anxiety compared with their counterparts. On average, students report higher anxiety in their large-enrollment online college science courses compared with their large-enrollment in-person college science courses. Students with depression and students with higher GPAs were disproportionately likely to report having higher anxiety in large-enrollment online courses compared with in-person courses. Students most frequently reported having higher anxiety online because it was difficult to learn online, stay on top of their assignments, and make connections with other students. We also assessed what factors generally contributed to students’ anxiety in their large-enrollment online college science courses. The most frequently reported factors that increase student anxiety online were technological issues, proctored exams, and difficulty getting to know other students. In contrast, being able to access content at a later time, the flexibility of attending class from where a student wants, and not having to be on camera were the most commonly reported factors that decrease students’ anxiety in their large-enrollment online college science courses. Student gender, race/ethnicity, LGBTQ+ status, and whether or not they had depression commonly predicted what specific factors affected their anxiety. Finally, students identified 10 ways in which instructors can alleviate student anxiety in their courses, including increasing test-taking flexibility, being flexible and understanding, and having an organized course. This research provides concrete ways that instructors of large-enrollment college science courses can create more inclusive online learning environments for students with anxiety.
