Abstract
Laboratory practicals in life science subjects are traditionally assessed by written reports that reflect disciplinary norms for documenting experimental activities. However, the exclusive application of this assessment has the potential to engage only a narrow range of competencies. In this study, we explored how multiple modes of laboratory assessment might affect student perceptions of learned skills in a life science module. We hypothesized that while a mixture of assessments may not impact student summative performance, it might positively influence student perceptions of different skills that varied assessments allowed them to practice. This was informed by universal design for learning and teaching for understanding frameworks. In our study, in a third-year Bioscience program, written reports were complemented with group presentations and online quizzes via Moodle. Anonymous surveys evaluated whether this expanded portfolio of assessments promoted awareness of, and engagement with, a broader range of practical competencies. Aspects that influenced student preferences in assessment mode included time limitations, time investment, ability to practice new skills, links with lecture material, and experience of assessment anxiety. In particular, presentations were highlighted as promoting collaboration and communication and the quiz as an effective means of diversifying assessment schedules. A key takeaway from students was that while reports were important, an overreliance on them was detrimental. This study suggests that undergraduate life science students can benefit significantly from a holistic assessment strategy that complements reports with performance-based approaches that incorporate broader competencies and allow for greater student engagement and expression in undergraduate modules.NEW & NOTEWORTHY This study suggests that undergraduate life science students can benefit significantly from a holistic assessment strategy that complements reports with performance-based approaches that incorporate broader competencies and allow for greater student engagement and expression in undergraduate modules.

Abstract
Primarily undergraduate institutions (PUI) often struggle to provide authentic research opportunities that culminate in peer-reviewed publications due to "recipe-driven" lab courses and the comprehensive body of work necessary for traditional scientific publication. However, the advent of short-form, single-figure "micropublications" has created novel opportunities for early-career scientists to make and publish authentic scientific contributions on a scale and in a timespan compatible with their training periods. The purpose of this qualitative case study is to explore the benefits accrued by eight undergraduate and master's students who participated in authentic, small-scale research projects and disseminated their work as coauthors of peer-reviewed micropublications at a PUI. In these interviews, students reported that through the process of conducting and publishing their research, they developed specific competencies: reading scientific literature, proposing experiments, and collecting/interpreting publication-worthy data. Further, they reported this process enabled them to identify as contributing members of the greater scientific community.

Abstract
Novel approaches in higher education are needed to reverse underrepresentation of racial/ethnic groups in science, technology, engineering, mathematics, and medicine (STEMM). Building on theoretical frameworks for practice in diverse learning environments, this study provides evidence for Inclusive Science as a conceptual model that reflects initiatives intended to diversify biomedical research training for undergraduates. Using multiple case study design and cross-case analysis, we analyzed data from 10 higher education sites that were awarded the Building Infrastructure Leading to Diversity (BUILD) grant funded by the National Institutes of Health (NIH). We identified the following dimensions of the Inclusive Science model: promoting participation of diverse researchers; introducing diversity innovations in science and research curriculum; improving campus climate for diversity; providing tangible institutional support; creating partnerships with diverse communities; and integrating students' social identities with science identity. We illustrate each dimension of the model with examples of campus practices across BUILD sites. While many may doubt that science can be responsive to diversity, the interventions developed by these campuses illustrate how colleges and universities can actively engage in culturally responsive practices in STEMM undergraduate training that integrate trainees' identities, knowledge of diverse communities, and create a greater awareness of the climate for diversity that affects student training and outcomes. Implications include culturally responsive strategies that many more higher education institutions can employ to support scientific career training for historically excluded groups.

Abstract
Undergraduate research experiences benefit students by immersing them in the work of scientists and often result in increased interest and commitment to careers in the sciences. Expanding access to Research Experience for Undergraduate (REU) programs has the potential to engage more students in authentic research experiences earlier in their academic careers and grow and diversify the geoscience workforce. The Research Experience for Community College Students (RECCS) was one of the first National Science Foundation (NSF)-funded REU programs exclusively for 2-year college students. In this study, we describe findings from five years of the RECCS program and report on outcomes from 54 students. The study collected closed- and open-ended responses on post-program reflection surveys to analyze both student and mentor perspectives on their experience. Specifically, we focus on students' self-reported growth in areas such as research skills, confidence in their ability to do research, and belonging in the field, as well as the mentors' assessment of students' work and areas of growth, and the impact of the program on students' academic and career paths. In addition, RECCS alumni were surveyed annually to update data on their academic and career pursuits. Our data show that RECCS students learned scientific and professional skills throughout the program, developed a sense of identity as a scientist, and increased their interest in and excitement for graduate school after the program. Through this research experience, students gained confidence in their ability to "do" science and insight into whether this path is a good fit for them. This study contributes to an emerging body of data examining the impact of REU programs on community college students and encourages geoscience REU programs to welcome and support more community college students.

Abstract
While several studies have investigated gender inequities in the social learning environment of biology lecture courses, that same phenomenon remains largely unexplored in biology laboratory contexts. We conducted a mixed methods study to understand the influence of gender on student perceptions of their peers' research aptitude in introductory biology CUREs and traditional laboratory courses. Specifically, students (N = 125) were asked to complete a name generator survey at three time points across the semester. This survey asked students to list the names of peers whom they viewed as "most proficient" in the course investigations and to justify their choice via an open-ended response prompt. Using social network analysis, exponential random graph modeling (ERGM), and thematic analysis, we demonstrate that student gender identity did not influence nomination behaviors in CURE or traditional laboratory courses. However, the ERGMs reveal the presence of a popularity effect in CUREs and demonstrate that mutual nominations were more prevalent in traditional laboratory courses. Our qualitative data further provide insights into the reasons students nominated peers as proficient in CURE and traditional courses.

Abstract
Course-based undergraduate research experiences (CUREs) offer an expanding avenue to engage students in real-world scientific practices. Increasingly, CUREs are instructed by graduate teaching assistants (TAs), yet TAs may be underprepared to facilitate and face unique barriers when teaching CUREs. Consequently, unless TAs are provided professional development (PD) and resources to teach CUREs effectively, they and their students may not reap the assumed benefits of CURE instruction. Here, we describe three perspectives - that of the CURE TA, the CURE designer/facilitator, and the CURE student - that are collectively intended to inform the development of tentative components of CURE TA PD. We compare these perspectives to previous studies in the literature in an effort to identify commonalities across all sources and offer potential insights for advancing CURE TA PD efforts across a diversity of institutional environments. We propose that the most effective CURE TA PD programs will promote the use of CURE-specific instructional strategies as benchmarks for guiding change in teaching practices and should focus on three major elements: 1) enhancement of research and teaching acumen, 2) development of effective and inclusive mentoring practices, and 3) identification and understanding of the factors that make CUREs a unique learning experience.

Abstract
Research has shown that undergraduate research experiences can have substantive effects on retaining students in science, technology, engineering and mathematics (STEM). However, it is impossible to provide individual research experiences for every undergraduate student, especially at large universities. Course-based undergraduate research experiences (CUREs) have become a common approach to introduce large numbers of students to research. We investigated whether a one-semester CURE that replaced a traditional introductory biology laboratory course could increase retention in STEM as well as intention to remain in STEM, if the results differed according to demography, and investigated the possible motivational factors that might mediate such an effect. Under the umbrella of the Authentic Research Connection (ARC) program, we used institutional and survey data from nine semesters and compared ARC participants to non-participants, who applied to ARC but either were not randomly selected or were selected but chose not to enroll in an ARC section. We found that ARC had significant effects on demographic groups historically less likely to be retained in STEM: ARC participation resulted in narrowing the gaps in graduation rates in STEM (first vs continuing-generation college students) and in intention to major in STEM [females vs males, Persons Excluded because of Ethnicity or Race (PEERs) vs non-PEERs]. These disproportionate boosts in intending STEM majors among ARC students coincide with their reporting a greater sense of student cohesiveness, retaining more interest in biology, and commenting more frequently that the course provided a useful/valuable learning experience. Our results indicate that CUREs can be a valuable tool for eliminating inequities in STEM participation, and we make several recommendations for further research.

Abstract
Laboratory courses can serve as important avenues to equitably support introductory biology students to develop foundational scientific literacy skills while experiencing the authentic research process. We present a model for an equity-focused redesign of an introductory organismal biology laboratory course at a teaching institution with limited research infrastructure. We incorporated elements of inquiry, structure, and climate into our three redesigned course components: weekly research investigations, skill-building assignments, and student-designed group projects. Students were trained in the research process through weekly experiments using locally relevant model organisms, collecting and analyzing novel data and writing brief results sections in the conventions of a research journal article. Student groups then collaborated to complete a student-designed research project and poster presentation using one of the model organisms. Through weekly inquiry labs and practice in skill-building assignments, most students in the sample mastered skills in analyzing, graphing, and writing about experimental results. Notably, students mastered skills that were practiced more frequently throughout the lab course, demonstrating the value of repeated and scaffolded practice. Students reported significant gains in self-efficacy and science identity, as well as sense of project ownership. Student gains were influenced by instructor but not their major or the semester in which they took the course, and growth occurred across students regardless of their incoming score on the presemester survey. This intentional course design model, combined with consistent expectations for instructors across multiple sections, has the potential to equitably support students with a range of prior knowledge and experiences to make meaningful gains in science literacy skills during an introductory semester.

Abstract
Course-based undergraduate research experiences (CUREs) have emerged as a viable platform to engage large numbers of students in real-world scientific practices. Historically, CUREs have been offered throughout science, technology, engineering, and mathematics curricula at both the introductory and advanced levels and have been facilitated by a variety of individuals, including faculty members, postdoctoral fellows, and graduate teaching assistants (GTAs). This latter population, in particular, has increasingly been tasked with facilitating CUREs, yet they often receive little meaningful professional development to improve pedagogical skills vital to this type of instruction. To address this disparity, we designed and evaluated a semester-long intervention to support GTAs (N = 7) responsible for leading CUREs at our institution during the Fall 2020 semester. Intervention activities included synchronous interactive discussions, reflective journaling, and asynchronous practical exercises. Analysis of retrospective postintervention survey responses and focus group interview data revealed that participants exhibited gains in their understanding of the dimensions of CUREs, strategies for mentoring undergraduates, and use of various pedagogical techniques as well as confidence in addressing and adopting those dimensions and strategies in their courses. Furthermore, participants reported finding value in the sense of community created through the intervention, which served as a means to share ideas and struggles throughout the term.

Abstract
Course-based undergraduate research experiences (CUREs) rapidly have become more common in biology laboratory courses. The effort to implement CUREs has stimulated attempts to differentiate CUREs from other types of laboratory teaching. The Laboratory Course Assessment Survey (LCAS) was developed to measure students' perceptions of how frequently they participate in activities related to iteration, discovery, broader relevance, and collaboration in their laboratory courses. The LCAS has been proposed as an instrument that can be used to define whether a laboratory course fits the criteria for a CURE or not. However, the threshold LCAS scores needed to define a course as a CURE are unclear. As a result, we examined variation in published LCAS scores among different laboratory course types. In addition, we examined the distribution of LCAS scores for students enrolled in our research-for-credit course. Overall, we found substantial variation in scores among CUREs and broad overlap among course types in scores related to all three scales measured by the LCAS. Furthermore, the mean LCAS scores for all course types fell within the main part of the distribution of scores for our mentored research students. These results suggest that the LCAS cannot be used to easily quantify whether a course is a CURE or not. We propose that the biology education community needs to move beyond trying to quantitatively identify whether a course is a CURE. Instead, we should use tools like the LCAS to investigate what students are actually doing in their laboratory courses and how those activities impact student outcomes.

Abstract
COVID-19 necessitated the rapid transition to online learning, challenging the ability of Science, Technology, Engineering, and Math (STEM) professors to offer laboratory experiences to their students. As a result, many instructors sought online alternatives. In addition, recent literature supports the capacity of online curricula to empower students of historically underrepresented identities in STEM fields. Here, we present PARE-Seq, a virtual bioinformatics activity highlighting approaches to antimicrobial resistance (AMR) research. Following curricular development and assessment tool validation, pre- and post-assessments of 101 undergraduates from 4 institutions revealed that students experienced both significant learning gains and increases in STEM identity, but with small effect sizes. Learning gains were marginally modified by gender, race/ethnicity, and number of extracurricular work hours per week. Students with more extracurricular work hours had significantly lower increase in STEM identity score after course completion. Female-identifying students saw greater learning gains than male-identifying, and though not statistically significant, students identifying as an underrepresented minority reported larger increases in STEM identity score. These findings demonstrate that even short course-based interventions have potential to yield learning gains and improve STEM identity. Online curricula like PARE-Seq can equip STEM instructors to utilize research-driven resources that improve outcomes for all students, but support must be prioritized for students working outside of school.

Abstract
To expose all undergraduate science students to the benefits of participating in research, many universities are integrating course-based undergraduate research experiences (CUREs) into their introductory biology laboratory curriculum. At large institutions, the bulk of introductory labs are instructed by graduate teaching assistants (GTAs). Graduate students, who are often teachers and researchers in training, may vary in their capacity to effectively teach undergraduates via the CURE model. To explore variation in GTA teaching and the subsequent outcomes for students, we used a case study research design at one institution where introductory biology students participate in GTA-taught CURE lab sections. We used multiple data sources, including in-class focus groups, worksheets, and surveys to explore student perceptions of the GTA-led CURE. Students perceived variation both in the ability of their GTAs to create a supportive and comfortable learning environment, and in the instructional priorities of their GTAs. We also compared student and GTA perspectives of student engagement with research elements in the CURE. While GTAs were divided in their perceptions of whether the CURE provided students with the opportunity to experience the element of relevant discovery, most students—regardless of their GTA—did not perceive that relevant discovery was emphasized in the CURE. Finally, individual GTAs seemed to influence how students perceived why they were participating in the CURE. These data imply that students in CUREs may have vastly different and potentially inequitable research experiences depending on their instructor.

Students' Emotions, Perceived Coping, and Outcomes in Response to Research-Based Challenges and Failures in Two Sequential CUREs. CBE LIFE SCIENCES EDUCATION 2022; 21:ar23.

Abstract
The ability to navigate scientific obstacles is widely recognized as a hallmark of a scientific disposition and is one predictor of science, technology, engineering, and mathematics persistence for early-career scientists. However, the development of this competency in undergraduate research has been largely underexplored. This study addresses this gap by examining introductory students' emotional and behavioral responses to research-related challenges and failures that occur in two sequential research-based courses. We describe commonly reported emotions, coping responses, and perceived outcomes and examine relationships between these themes, student demographics, and course enrollment. Students commonly experience frustration, confusion, and disappointment when coping with challenges and failures. Yet the predominance of students report coping responses likely to be adaptive in academic contexts despite experiencing negative emotions. Being enrolled in the second course of a research-based course sequence was related to several shifts in response to challenges during data collection, including less reporting of confusion and fewer reports of learning to be cautious from students. Overall, students in both the first and second courses reported many positive outcomes indicating improvements in their ability to cope with challenge and failure. We assert that educators can improve research-based educational courses by scaffolding students' research trials, failures, and iterations to support students' perseverance.

Abstract
Disseminating and communicating scientific findings is an acknowledged part of the research experience, but few science programs include explicit undergraduate curricula for practicing oral science communication. Course-based undergraduate research experiences (CUREs) can provide opportunities for students to practice science communication, but few studies describe or assess authentic oral science communication activities within CUREs, and none do so under hybrid conditions. The existing literature lacks substantial evidence for how science communication activities impact students' science identity and science communication self-efficacy, specifically regarding research posters. To address this, we collected students' quantitative and qualitative perceptions of science identity and science communication self-efficacy in a hybrid CURE and collected students' qualitative perceptions of presenting their research remotely at a virtual poster symposium. We found that students' science identity and science communication self-efficacy improved significantly, as well as benefits and complaints about presenting research virtually, namely, reduced stress, a more comfortable atmosphere, but a murkier communication channel. Our results should prove valuable to educators interested in improving students' science identity and science communication self-efficacy, especially when limited to a virtual or hybrid format, as affective factors strongly impact students' persistence in science.

Abstract
The integration of course-based undergraduate research experiences (CUREs) into science, technology, engineering, and mathematics (STEM) laboratory curricula has provided new avenues to engage students at all levels in discovery-based learning. Empirical research demonstrates that CUREs have the potential to foster students' development of scientific process and reasoning skills, attitudes, motivations, and persistence in STEM. Yet, these outcomes are largely reported for studies conducted in the United States, Canada, Europe, and Australia. It therefore remains unclear to what extent CUREs are impactful for students enrolled in alternate international university contexts. To address this concern, we conducted a quasi-experimental mixed methods study to investigate the impact of a one-semester food microbiology and public health (FMPH) CURE on nonmajors students' development of science identity, science communication and process skills, science community values, and science-society perceptions at a private institution in Côte d'Ivoire, West Africa. Content analysis of students' end-of-semester research poster products and thematic analysis of student responses to post-semester open-ended survey items revealed positive gains with respect to student learning and student perceptions of the relevancy of their research to diverse audiences. Paired t-test analyses of pre-/post-semester closed-ended survey responses likewise indicated significant gains in students' science identity and science community values development as well as their confidence in handling and treating foods to reduce the bacterial load on those foods. Collectively, these findings suggest that the FMPH CURE was a meaningful and relevant learning experience capable of promoting students' growth as scientists and scientifically-minded citizens.

Abstract
The COVID-19 pandemic ushered in an unprecedented period of both crisis and innovation in higher education. The shift to an online learning environment was particularly problematic for courses in which students learn disciplinary practices. Scientific practice requires hands-on training and collaborative engagement with instructors and peers, dimensions of the learning environment that were challenging to recreate online. Here, we describe the resulting instructional innovations and challenges experienced in shifting multiple undergraduate- and graduate-level molecular bioscience labs, including Genetics, Cell Biology, Bioinformatics, and Advanced Microscopy, to an online learning environment. Instructors pursued novel approaches, techniques, and at-home lab tools with varying success. Many innovations were retained after the transition back to an in-person learning environment because they uniquely supported previously overlooked aspects of student learning. Consistent with other reports, we found that marginalized students pursuing science were disproportionately burdened by COVID-19 and the shift to an online learning environment. A description of what worked for online learning, what didn’t, and what is worth holding onto in the future is valuable for constructing learning environments that effectively support learners in their disciplinary practice.

Abstract
Course-based research experiences (CREs) are designed to engage students in authentic scientific experiences that are embedded into a standard curriculum. CREs provide valuable research experiences to large numbers of undergraduate biology students, however, CRE implementation can require many personnel. Because limited personnel may be a barrier to widespread CRE implementation, our goal was to discover which personnel students valued throughout a CRE and the ways they were valuable. We investigated students’ perceptions of personnel resources throughout a semester-long CRE using two survey approaches. Using a text message survey administered multiple times per week, real-time data was collected about which personnel resource students perceived to be the most helpful. Using a web-based survey administered five times throughout the semester, retrospective data was collected about how often students used each personnel resource and how helpful students perceived each personnel resource to be. Graduate teaching assistants (TAs) were consistently selected as the most helpful personnel resource by the majority of respondents throughout the semester, with most respondents describing graduate TAs providing project-specific feedback. Although less frequently, undergraduate TAs were also consistently selected as the most helpful personnel resource. Respondents described undergraduate TAs providing project-specific feedback, general feedback, and project-specific resources. Data from the retrospective, web-based survey largely mirrored the real-time, text message survey data. Throughout the semester, most respondents reported using graduate TAs “Often” or “Always” and that graduate TAs were “Very” or “Extremely” helpful. Throughout most of the semester, most respondents also reported using undergraduate TAs “Often” or “Always” and that undergraduate TAs were “Very” or “Extremely” helpful. The results of this descriptive study underscore the importance of graduate and undergraduate TAs in the development and implementation of CREs, emphasizing the need for departments and course coordinators to be intentional in planning TA training that prepares TAs to fulfill their critical role in CRE implementation.

Abstract
Development of key practical skills is fundamental to bioscience courses in higher education. With limitations on access to laboratory time due to the COVID-19 pandemic, a “Bioskills at home” kit was developed to create opportunities for first year undergraduate students to develop these skills using online support resources to guide their activities and build communities of learning. Equipment and activities in this kit enabled students to practice key skills such as pipetting, data handling, experimental design and microscopy, as well as build an online peer learning community through the use of discussion boards and microscopy competitions that encouraged students to explore their local environment. Students who engaged with these activities reported increased confidence in key practical skills. Practical assessment of skills showed that that there was no reduction in the proportion of students who succeeded in achieving the pipetting learning objective compared to previous years, despite a significantly reduced on-campus provision. Although the celebration event to choose the microscopy competition winners was well attended, there was limited use of the discussion boards by students to build a community of learning during the term. Refinement of this initiative will focus on providing greater scaffolding to encourage greater engagement with activities and enhance community building.

Abstract
Course-based undergraduate research experiences (CUREs) offer a powerful approach to engage students at all academic levels in the process of scientific discovery. In comparison to prescriptive laboratory exercises, CUREs have been shown to promote students' science process skill development, positive attitudes toward scientific research, and persistence in STEM. While this is the case, descriptions of CUREs within the literature vary widely, particularly in the extent to which they explicitly address the five posited dimensions of CUREs. This can present as a challenge to both novice CURE facilitators, who may be unfamiliar with CURE terminology, as well as the CURE community as a whole, who seek to understand what facets of CUREs impact student outcomes. In response, we created the "Dimensions of CUREs Informational Template" (DoC IT), a professional development tool amenable for use with CURE designers, facilitators, and evaluators. Application of this tool is intended as a viable step in achieving a unified way to discuss CUREs in both intra- and interinstitutional contexts.

Abstract
Despite growing evidence of positive student outcomes from course-based undergraduate research experiences (CUREs), little consideration has been given to employing graduate teaching assistants (GTAs) as CURE instructors. GTAs may be novice researchers and/or teachers and likely vary in their interest in teaching a CURE. Guided by expectancy-value theory, we explored how GTAs' self-efficacy and values regarding teaching a CURE impact motivation and perceptions of their roles as CURE instructors. Using a multiple case study design, we interviewed nine GTAs who taught a network CURE at one research institution. Though most GTAs held a relatively high value for teaching a CURE for a range of reasons, some GTAs additionally perceived high costs associated with teaching the CURE. Through the interview data, we established three profiles to describe GTA perceptions of their role as CURE instructors: "Student Supporters," "Research Mentors," and "Content Deliverers." Those implementing GTA-led CUREs should consider that GTAs likely have different perceptions of both their role in the classroom and the associated costs of teaching a CURE. The variability in GTA perceptions of CUREs implies that undergraduate students of different GTAs are unlikely to experience the CURE equivalently.

Abstract
Course-based undergraduate research experiences (CUREs), which often engage students as early as freshman year, have become increasingly common in biology curricula. While many studies have highlighted the benefits of CUREs, little attention has been paid to responsible and ethical conduct of research (RECR) education in such contexts. Given this observation, we adopted a mixed methods approach to explore the extent to which RECR education is being implemented and assessed in biological sciences CUREs nationwide. Survey and semistructured interview data show a general awareness of the importance of incorporating RECR education into CUREs, with all respondents addressing at least one RECR topic in their courses. However, integration of RECR education within the CURE environment primarily focuses on the application of RECR during research practice, often takes the form of corrective measures, and appears to be rarely assessed. Participants reported lack of time and materials as the main barriers to purposeful inclusion of RECR education within their courses. These results underscore a need for the CURE community to develop resources and effective models to integrate RECR education into biology CUREs.

Abstract
Recent efforts to reform postsecondary STEM education in the U.S. have resulted in the creation of course-based undergraduate research experiences (CUREs), which, among other outcomes, have successfully retained freshmen in their chosen STEM majors and provided them with a greater sense of identity as scientists by enabling them to experience how research is conducted in a laboratory setting. In 2014, we launched our own laboratory-based CURE, Brain Mapping & Connectomics (BMC). Now in its seventh year, BMC trains University of Texas at El Paso (UTEP) undergraduates to identify and label neuron populations in the rat brain, analyze their cytoarchitecture, and draw their detailed chemoarchitecture onto standardized rat brain atlas maps in stereotaxic space. Significantly, some BMC students produce atlas drawings derived from their coursework or from further independent study after the course that are being presented and/or published in the scientific literature. These maps should prove useful to neuroscientists seeking to experimentally target elusive neuron populations. Here, we review the procedures taught in BMC that have empowered students to learn about the scientific process. We contextualize our efforts with those similarly carried out over a century ago to reform U.S. medical education. Notably, we have uncovered historical records that highlight interesting resonances between our curriculum and that created at the Johns Hopkins University Medical School (JHUMS) in the 1890s. Although the two programs are over a century apart and were created for students of differing career levels, many aspects between them are strikingly similar, including the unique atlas-based brain mapping methods they encouraged students to learn. A notable example of these efforts was the brain atlas maps published by Florence Sabin, a JHUMS student who later became the first woman to be elected to the U.S. National Academy of Sciences. We conclude by discussing how the revitalization of century-old methods and their dissemination to the next generation of scientists in BMC not only provides student benefit and academic development, but also acts to preserve what are increasingly becoming "lost arts" critical for advancing neuroscience - brain histology, cytoarchitectonics, and atlas-based mapping of novel brain structure.

Abstract
We previously developed and assessed "The Art of Microbiology," a course-based undergraduate research experience (CURE) which uses agar art to spur student experimentation, where we found student outcomes related to science persistence. However, these outcomes were not correlated with specific activities and gains were not reported from more than one class. In this study, we explored which of the three major activities in this CURE-agar art, experimental design, or poster presentations-affected student engagement and outcomes associated with improved understanding of the nature of science (NOS). The Art of Microbiology was studied in three microbiology teaching laboratories: at a research university with either the CURE developer (18 students) or a CURE implementer (39 students) and at a community college with a CURE implementer (25 students). Our quasi-experimental mixed methods study used pre/post-NOS surveys and semi-structured class-wide interviews. Community college students had lower baseline NOS responses but had gains in NOS similar to research university students post-CURE. We surveyed research university students following each major activity using the Assessing Student Perspective of Engagement in Class Tool (ASPECT) survey but did not find a correlation between NOS and activity engagement. Of the three activities, we found the highest engagement with agar art, especially in the CURE developer class. Interviewed students in all classes described agar art as a fun, relevant, and low-stakes assignment. This work contributes to the evidence supporting agar art as a curricular tool, especially in ways that can add research to classrooms in and beyond the research university.

Abstract
Connections, collaborations, and community are key to the success of individual scientists as well as transformative scientific advances. Intentionally building these components into STEM education can better prepare future generations of researchers. Course-based undergraduate research experiences (CUREs) are a new and fast-growing teaching practice in STEM that can expand opportunities for undergraduate students to gain research skills. Because they engage all students in a course in an authentic research experience focused on a relevant scientific problem, CUREs provide an opportunity to foster community among students while promoting critical thinking skills and positively influencing their identities as scientists. Here, we review CUREs in the biological sciences that were developed as multi-institutional networks, and highlight the benefits gained by both students and instructors through participation in a CURE network. Throughout, we introduce Squirrel-Net, a network of ecology-focused and field-based CUREs that intentionally create connections among students and instructors. Squirrel-Net CUREs can also be scaffolded into the curriculum to form connections between courses, and are easily transitioned to distance-based delivery. Future assessments of networked CUREs like Squirrel-Net will help elucidate how CURE networks create community and how a cultivated research community impacts students' performance, perceptions of science, and sense of belonging. We hypothesize networked CUREs have the potential to create a broader sense of belonging among students and instructors alike, which could result in better science and more confident scientists.

Abstract
Science self-efficacy, a student's confidence in being able to perform scientific practices, interacts with science identity and outcomes expectations, leading to improved performance in science courses, persistence in science majors, and ultimately, the pursuit of advanced training in the sciences. Inquiry-based laboratory courses have been shown to improve undergraduate student self-efficacy, but the mechanisms involved and specific components of instructional practices that lead to improved self-efficacy are not clear. In the current study, we determined whether student and faculty perceptions of laboratory instructional practices (scientific synthesis, science process skills, and instructor-directed teaching) were related to postsemester self-efficacy across 19 guided-inquiry laboratory courses from 11 different institutions. Self-efficacy related to science literacy increased significantly from the beginning of the semester to the end of the semester. Variation in individual student perceptions of instructional practices within a course were significantly related to differences in student self-efficacy at the end of the semester, but not average student perceptions or faculty perceptions of their own practices across courses. The importance of individual student perceptions suggests that faculty should engage with students during curricular development. Furthermore, faculty need to use noncontent talk to reinforce the science practices students are engaging in during inquiry-based laboratory courses.

Abstract
Course-based undergraduate research experiences (CUREs) and inquiry-based curricula both expose students to the scientific process. CUREs additionally engage students in novel and scientifically relevant research, with the intention of providing an "authentic" research experience. However, we have little understanding of which course design elements impact students' beliefs that they are experiencing "authentic" research. We designed a study to explore introductory biology students' perceptions of research authenticity in CURE and inquiry classes. Using the Laboratory Course Assessment Survey, we found that students in CURE sections perceived higher levels of authentic research elements than students in inquiry-based sections. To identify specific factors that impact perceptions of research authenticity, we administered weekly reflection questions to CURE students. Coding of reflection responses revealed that experiences of failure, iteration, using scientific practices, and the relevant discoveries in their projects enhanced students' perceived authenticity of their research experiences. Although failure and iteration can occur in both CUREs and inquiry-based curricula, our findings indicate these experiences-in conjunction with the Relevant Discovery element of a CURE-may be particularly powerful in enhancing student perceptions of research authenticity in a CURE.

Abstract
The transition to online learning in spring 2020 was abrupt for both students and instructors. While many instructors moved to asynchronous classes, some institutions relied more heavily on synchronous online courses. Here, we evaluate student perceptions of an inquiry-based molecular biology lecture and lab course following this transition by comparing student survey responses from spring 2019, when the lecture and lab were fully in person, to spring 2020, when the lecture and lab started in person before transitioning to a synchronous online format. Students were asked to identify the main factors that supported their learning in lecture and lab, characterize the main barriers to learning in those courses, and discuss their preference of having an inquiry-based lab or a traditional "cookbook" lab with pre-determined answers. We coded these responses and provide one of the first studies to examine the impact of this online transition on student perceptions of learning in an inquiry-based molecular biology lecture and lab course.

Abstract
The University of British Columbia has developed a course-based undergraduate research experience (CURE) that engages students in authentic molecular microbiology research. This capstone course is uniquely built around an open-access online undergraduate research journal entitled Undergraduate Journal of Experimental Microbiology and Immunology (UJEMI). Students work in teams to derive an original research question, formulate a testable hypothesis, draft a research proposal, carry out experiments in the laboratory, and publish their results in UJEMI. The CURE operates in a feed forward manner whereby student-authored UJEMI publications drive research questions in subsequent terms of the course. Progress toward submission of an original manuscript is scaffolded using a series of communication assignments which facilitate formative development. We present a periodic model of our CURE that guides students through a research cycle. We review two ongoing course-based projects to highlight how UJEMI publications prime new research questions in the course. A journal-driven CURE represents a broadly applicable pedagogical tool that immerses students in the process of doing science.
