The Current Insights feature highlights diverse perspectives on education from beyond the LSE community. In this installment, I have chosen articles that offer different perspectives on the surge of interest in integrating computation into science learning. These articles present theoretical frameworks, propose methodological approaches, and raise critical questions about the purpose and impact of making computation foundational to science education.

Fear of negative evaluation (FNE), defined as a sense of dread associated with being negatively judged in a social situation, has been identified as the primary factor underlying undergraduate anxiety in active-learning science courses. However, no quantitative studies have examined the extent to which science undergraduates experience FNE and how they are impacted by FNE in college science courses. To address this gap, we surveyed 566 undergraduates from one university in the U.S. Southwest who were enrolled in life sciences courses where they had opportunities to speak in front of the whole class. Participants were asked a suite of questions regarding their experiences with FNE in large-enrollment college science courses. We found that first-generation college students, LGBTQ+ students, and students with disabilities reported disproportionately high levels of FNE compared with their counterparts. Additionally, students reported that FNE can cause them to overthink their responses and participate less in class. Participants rated being cold called and presenting alone as forms of whole-class participation that elicit the highest levels of FNE. This research highlights the impact of FNE on undergraduates and provides student-generated recommendations to reduce FNE in active-learning science courses.

Traditional biology curricula depict science as an objective field, overlooking the important influence that human values and biases have on what is studied and who can be a scientist. We can work to address this shortcoming by incorporating ideological awareness into the curriculum, which is an understanding of biases, stereotypes, and assumptions that shape contemporary and historical science. We surveyed a national sample of lower-level biology instructors to determine 1) why it is important for students to learn science, 2) the perceived educational value of ideological awareness in the classroom, and 3) hesitancies associated with ideological awareness implementation. We found that most instructors reported "understanding the world" as the main goal of science education. Despite the perceived value of ideological awareness, such as increasing student engagement and dispelling misconceptions, instructors were hesitant to implement ideological awareness modules due to potential personal and professional consequences.

Teaching undergraduate students to read primary scientific literature (PSL) is cited as an important goal for many science, technology, engineering, and math (STEM) classes, given a range of cognitive and affective benefits for students who read PSL. Consequently, there are a number of approaches and curricular interventions published in the STEM education literature on how to teach students to read PSL. These approaches vary widely in their instructional methods, target student demographic, required class time, and level of assessment demonstrating the method's efficacy. In this Essay, we conduct a systematic search to compile these approaches in an easily accessible manner for instructors, using a framework to sort the identified approaches by target level, time required, assessment population, and more. We also provide a brief review of the literature surrounding the reading of PSL in undergraduate STEM classrooms and conclude with some general recommendations for both instructors and education researchers on future areas of investigation.

COVID-19 created unprecedented challenges for college students, highlighting the need to provide educational contexts that foster well-being. Summer undergraduate research experiences (SUREs) constitute a high-impact practice, yet little systematic knowledge exists about how the first surge of COVID-19 influenced undergraduate researchers' well-being. This knowledge is important for preparing for future disruptions. This study applies the student well-being model (SWBM) to examine how SURE status (e.g., modification vs. cancellation) impacted students' mental health and graduate school intentions using primary survey data collected from U.S. undergraduate researchers in science, technology, engineering, and mathematics (STEM) fields in Summer 2020 (n = 408, from 131 institutions). Just under half had their SURE canceled, and the others engaged in modified SUREs. Students whose SUREs were canceled had reduced anxiety severity (p < 0.05), but greater concerns about graduate school matriculation (p < 0.001), compared with students with modified SUREs. Results suggest that modified SUREs are a reasonable path forward under conditions where in-person contact is untenable. Results point toward potential improvements in higher education practices that may enhance student well-being following disruptive events. Program directors can address potential causes of anxiety in modified SUREs, advocate for student-centered adjustments to graduate admission processes, and use experiences during COVID-19 as a springboard to broaden participation in undergraduate research.

Learning assistant (LA) programs train undergraduate students to foster peer discussion and facilitate active-learning activities in undergraduate science, technology, engineering, and mathematics (STEM) classes. Students who take courses that are supported by LAs demonstrate better conceptual understanding, lower failure rates, and higher satisfaction with the course. There is less work, however, on the impact that participating in LA programs has on the LAs themselves. The current study implements a pretest-posttest design to assess changes in LAs' metacognition and motivation to succeed in STEM across their first and second quarters as an LA. Our findings suggest that participating in this program may help LAs become more reflective learners, as was demonstrated by an increase in their scores on the Metacognitive Awareness Inventory (MAI) after the first quarter. LAs also showed increases on the Intrinsic Motivation and Self-Efficacy subscales of the Science Motivation Questionnaire. Students who participated in the program for an additional quarter continued to show increases in their MAI scores and maintained the gains that were observed in their motivation. Taken together, this work suggests that, in addition to benefiting the learner, LA programs may have positive impacts on the LAs themselves.

Expectancy-value theory of motivation (EVT) suggests that student values influence their likelihood of putting in the effort required to learn, and these values can be shaped by student characteristics, such as their experiences, sociodemographics, and disciplinary norms. To understand the extent to which these characteristics relate to students' values, we surveyed 1162 graduating science, technology, engineering, and mathematics (STEM) students across four universities using the previously developed and validated Survey of Teaching Beliefs and Practices for Undergraduates (STEP-U). The STEP-U survey included Likert questions to capture students' values of 27 cross-disciplinary skills and the frequency with which they experienced 27 instructional methods thought to develop particular skills. Exploratory factor analyses (EFA) showed an understandable factor structure for both students' perceived value of cross-disciplinary skills and frequency of classroom experiences. Using multiple regression, we identified differences in values that were associated with classroom experiences, STEM discipline, participation in undergraduate research, and student sociodemographics. Findings were generalizable across institutions and disciplines. The theoretical framework (EVT), the broad data collection (four institutions with multiple disciplines), and the type of data analyses (e.g., EFA) used provide theoretical, methodological, and practical contributions and suggest additional directions for future research.

College science courses continue to transition from traditional lecture to active learning, which has been shown to have both alleviating and exacerbating effects on undergraduate mental health. Notably, existing studies have primarily examined the relationship between active learning and anxiety, and no studies have specifically assessed the relationship between active learning and depression. To address this gap, we conducted hourlong exploratory interviews with 29 undergraduates from six institutions who identify as having depression and who had been enrolled in at least one active-learning college science course. We probed how undergraduates' depression affects their experiences in active learning, and in turn, what aspects of active-learning practices exacerbate or alleviate students' depressive symptoms. Students described that their depression negatively impacted their cognitive domains, which could make learning and social interactions challenging. Additionally, we found that the underlying aspects of active-learning practices that impact students' depression fall into four overarching categories: opportunities to compare oneself with others, socializing with others while learning, frequent formative evaluation, and engagement in learning. Each of these aspects of active learning could alleviate and/or exacerbate depressive symptoms. This work supports recommendations to create more inclusive active-learning courses for students with depression.

Reflective practices in education are widely advocated for and have become important components of professional reviews. The advantages of reflective practices are many; however, the literature often focuses on the benefits to students, rather than the benefits for the educators themselves. Additionally, the extant literature concerning reflective practices in education is laden with conflicting terminology and complex studies, which can inhibit educators' understanding of reflective practices and prevent their adoption. As such, this Essay serves as a primer for educators beginning reflective practices. It briefly describes the benefits to educators and different classifications and modalities of reflection and examines some of the challenges that educators may encounter.
