Abstract
This paper presents a phenomenographic investigation on students' experiences about research and poster presentations in a workshop-based undergraduate research experience with a focus on how the experience connects to the Science and Engineering Practices (SEPs) of the NRC A Framework for K-12 Science Education and the principles of CUREs. This provides insight into how these structured research experiences reflect particular SEPs and also elements of scientific practice that are not captured in the SEPs as they have been formulated previously. This work showcases the importance of future applications, failure, and creativity as additional science practices necessary for students to engage in authentic science. The SEPs and the additional elements of scientific practice are related to how students experience meaningful learning in the cognitive, psychomotor, and affective domains. Students highlighted the components of CUREs: importance of contributing relevant discoveries as a motivation for their research, the value of repetition and iteration in ensuring reliable and valid results, and the role of collaboration in seeing new perspectives and solving problems. As a result of presenting their results through a poster, students reported deeper understanding of their research topic, increased ability to articulate scientific concepts, and a better understanding of how to create a visually appealing poster. Students changed the vocabulary they used in their presentations to fit the knowledge level of their audience and highlighted their data in figures and explained other parts of their work in text. Moreover, they saw the poster as an outlet for their creativity.

Casper AM, Laporte MM. A CURE Lab in Introductory Biology at a Regional Comprehensive University Negatively Impacts Student Success in the Associated Lecture Course Among Students from Groups Underrepresented in Science. CBE LIFE SCIENCES EDUCATION 2024; 23:ar25. [PMID: 38771264 PMCID: PMC11235111 DOI: 10.1187/cbe.23-06-0122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 04/04/2024] [Accepted: 04/08/2024] [Indexed: 05/22/2024]
Abstract
Course-based undergraduate research experiences (CUREs) have been proposed as a mechanism to democratize access to the benefits of apprentice-style scientific research to a broader diversity of students, promoting inclusivity and increasing student success and retention. As we evaluate CUREs, it is essential to explore their effectiveness within the environments of regional comprehensive universities and community colleges, because they are important access points for a wide variety of students. It is also important to address the potential influence of volunteer bias, where students can opt to enroll in either the CURE or a traditional lab, on the outcomes of CUREs. We evaluated a CURE at a regional comprehensive university under conditions both with and without volunteer bias. We find that nonvolunteer students report a lower sense of discovery and relevance of the CURE compared with students who volunteered for the course. Importantly, we also find that our replacement of the traditional lab class with a CURE resulted in lower scores on exams in the associated lecture course among students who are both BIPOC and Pell eligible. We call for additional research on the effects of CUREs at nonresearch-intensive institutions and without volunteer bias, to better understand the impact of these classes.

Abstract
Laboratory courses offer a unique opportunity, and sometimes challenge, to engage students in projects where they can experience ownership and authentic science practices. An important science practice is writing, which can lead to increased learning about concepts and science communication. Experiencing a sense of ownership in research can lead to various student outcomes, such as increased motivation, greater interest in research, and higher retention in STEM fields. Although previous work has extracted aspects of ownership from students' descriptions of research experiences, studies have not examined directly how students define and perceive ownership. In addition, we do not have a clear idea of whether a sense of ownership is related to student attitudes toward scientific writing in a lab course setting. To better understand the relationship between ownership and writing directly from students' perspectives, we used analysis of student responses to surveys and interviews in an upper-division laboratory course. Using a grounded theory approach for the analysis of 167 survey responses and 9 interviews, we found that students have varying perceptions of project ownership, with the most frequent being opportunities to contribute ideas and shape the project (autonomy), doing the work, and leadership. Students largely perceived that increased ownership had positive influences on their writing, such as increased understanding and thinking, freedom in writing, and increased motivation. Learning about how students perceive ownership in the context of a lab course is useful for considering how lab course structure may support the development of a sense of ownership and may influence how we can engage students in meaningful writing practices.

Abstract
Course-based undergraduate research experiences (CUREs) increase student access to high impact research experiences. CUREs engage students in the scientific process by learning how to pose scientific questions, develop hypotheses, and generate data to test them. Environmental DNA (eDNA) is a growing field of research that is gaining accessibility through decreasing laboratory costs, which can make a foundation for multiple, engaging CUREs. This manuscript describes three case studies that used eDNA in an upper year undergraduate course. The first focusses on a systematic literature review of eDNA metadata reporting. The second describes the biomonitoring of brook trout in southern Ontario using eDNA. The third involves eDNA metabarcoding for freshwater fish detection in southern Ontario. Undergraduates were involved in the development and execution of experiments, scientific communication, the peer review process, and fundraising. Through this manuscript, we show the novel application of eDNA CUREs and provide a roadmap for other instructors interested in implementing similar projects. Interviews with seven students from these courses indicate the benefits experienced from taking these courses. We argue that the use of eDNA in CUREs should be expanded in undergraduate biology programs due to the benefit to students and the increasing accessibility of this technology.

Abstract
Researchers who work on course-based undergraduate research experiences (CUREs) and issues related to science, technology, engineering, and math (STEM) retention have begun exploring changes in student thinking about what it means to be a scientist. To support this effort, we developed rubrics to score answers to three open-response prompts: What does it mean to think like a scientist? What does it mean to do science? and Did you do real research in your coursename labs? The rubric development process was iterative and was based on input from the literature, experienced researchers, and early-career undergraduates. A post hoc analysis showed that the rubric elements map to 27 of 31 statements in the Culture of Scientific Research (CSR) framework, suggesting that scored responses to the three prompts can assess how well students understand what being a science professional entails. Scores on responses from over 400 students who were starting an introductory biology course for majors furnish baseline data from the rubrics and suggest that (i) undergraduates at this level have, as expected, a novice-level understanding of CSR, and (ii) level of understanding in novice students does not vary as a function of demography or academic preparation. Researchers and instructors are encouraged to add CSR to their list of learning objectives for CUREs and consider assessing it using the rubrics provided here.

Abstract
Genetic analysis in model systems using bioinformatic approaches provides a rich context for a concrete and conceptual understanding of gene structure and function. With the intent to engage students in research and explore disease biology utilizing the nematode Caenorhabditis elegans model, we developed a semester-long course-based undergraduate research experience (CURE) in a hybrid (online/in-person) learning environment-the gene-editing and evolutionary nematode exploration CURE (GENE-CURE). Using a combination of bioinformatic and molecular genetic tools, students performed structure-function analysis of disease-associated variants of uncertain significance (VUS) in human orthologs. With the aid of a series of workshop-style research sessions, students worked in teams of two to six members to identify a conserved VUS locus across species and design and test a polymerase chain reaction-based assay for targeted editing of a gene in the nematode and downstream genotyping. Research session discussions, responsible conduct of research training, electronic laboratory notebook, project reports, quizzes, and group poster presentations at a research symposium were assessed for mastery of learning objectives and research progress. Self-reflections were collected from students to assess engagement, science identity, and science efficacy. Qualitative analysis of these reflections indicated several gains suggesting that all students found many aspects of the GENE-CURE rewarding (learning process of research, self-confidence in research and science identity, and personal interest) and challenging (iterative research and failure, time management, COVID-19 pandemic, and life issues).

Abstract
Course-based Undergraduate Research Experiences (CUREs) are attractive solutions for scaling undergraduate research experiences at primarily undergraduate teaching institutions, where resources for faculty research activities can be limited. The Sustainable Interdisciplinary Research to Inspire Undergraduate Success (SIRIUS) project is a unique program that integrates CUREs, coordinated around a local real-world problem, throughout a biology department's curricula. The CUREs are scaffolded to provide all biology majors with multiple opportunities to engage in scientific investigations as they advance through introductory, intermediate, and advanced courses. In this mixed methods, cross-sectional study, we explore students' perceptions of the authenticity of their experiences as they progress through the SIRIUS CUREs. Triangulated data collected from two instruments indicated that students in advanced courses recognized more involvement in research activities and perceived greater authenticity in the science they were performing compared with introductory and intermediate students. Intermediate and advanced students perceived more opportunities for independence; however, experiences with failure and the influence these experiences had on the perceptions of authenticity was primarily observed with advanced students. This study contributes to the growing literature on CUREs with a focus on students from a primarily undergraduate institution with multiple minority-serving designations.

Abstract
The COVID-19 pandemic forced educators to teach in an online environment. This was particularly challenging for those teaching courses that are intended to support bench science research. This practitioner article tells the story of how an instructor transformed their Course-based Undergraduate Research Experience (CURE) using the Backwards Design Method into a synchronous online course. Research objectives in this transformed course included: conducting a literature review, identifying research questions and hypotheses based on literature, and developing practical and appropriate research methodologies to test these hypotheses. We provide details on how assignments were created to walk students through the process of research study design and conclude with recommendations for the implementation of an online CURE. Recommendations made by the instructor include scaffolding the design, building opportunities for collaboration, and allowing students to fail in order to teach the value of iteration. The Backwards Design framework naturally lends itself to a scaffolded instructional approach. By identifying the learning objectives and final assessment, the learning activities can be designed to help students overcome difficult concepts by filling in the gaps with purposeful instruction and collaborative opportunities. This present course also practiced iteration through the extensive feedback offered by the instructor and opportunities for students to revise their work as their understanding deepened. Anecdotally, based on end of course reviews, students overall had a positive experience with this course. Future work will examine the efficacy of student learning in this online environment and is forthcoming.

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
We developed labs on the evolution of antibiotic resistance to assess the costs and benefits of replacing traditional laboratory exercises in an introductory biology course for majors with a course-based undergraduate research experience (CURE). To assess whether participating in the CURE imposed a cost in terms of exam performance, we implemented a quasi-experiment in which four lab sections in the same term of the same course did the CURE labs, while all other students did traditional labs. To assess whether participating in the CURE impacted other aspects of student learning, we implemented a second quasi-experiment in which all students either did traditional labs over a two-quarter sequence or did CURE labs over a two-quarter sequence. Data from the first experiment showed minimal impact on CURE students' exam scores, while data from the second experiment showed that CURE students demonstrated a better understanding of the culture of scientific research and a more expert-like understanding of evolution by natural selection. We did not find disproportionate costs or benefits for CURE students from groups that are minoritized in science, technology, engineering, and mathematics.

Abstract
Previously, we described a course-based undergraduate research experience (CURE) for first-year students that featured a unique approach to brain mapping in a model organism (rat). In response to the COVID-19 pandemic, we adapted this course for an online learning environment, emphasizing image analysis (identifying immunoreactive signal in an immunohistochemical stain, making neuroanatomical distinctions in a cytoarchitectural stain) and translation of image data to the brain atlas. Using a quasiexperimental mixed methods approach, we evaluated aspects of student engagement and perceived gains in student confidence with respect to the nature and process of science and student science identity development. Additionally, we examined the dynamics of mentorship and student connectedness experienced in the online-only context. We found that the majority of students reported positive affective outcomes for the course in domains such as project ownership and project engagement in addition to positive responses toward perceived mentorship received during the course. Unsurprisingly, students expressed frustration in not being able to freely communicate with members of the course in an organic face-to-face environment. Furthermore, we found that students encountered greater difficulty in mastering image software skills causing a delay in producing consistent-quality data maps. From our analysis of the course, we have identified both useful approaches and areas for course improvement in any future iterations of the online research course.NEW & NOTEWORTHY Herein, we describe the process of converting a novel, face-to-face neuroanatomy course-based undergraduate research experience (CURE) to an online-only research setting. We document student affective and skill gains resultant from participating in this course and examine best practices for structuring online CUREs to maximize student learning and success.

Abstract
Course-based undergraduate research experiences (CUREs) are laboratory courses that integrate broadly relevant problems, discovery, use of the scientific process, collaboration, and iteration to provide more students with research experiences than is possible in individually mentored faculty laboratories. Members of the national Malate dehydrogenase CUREs Community (MCC) investigated the differences in student impacts between traditional laboratory courses (control), a short module CURE within traditional laboratory courses (mCURE), and CUREs lasting the entire course (cCURE). The sample included approximately 1,500 students taught by 22 faculty at 19 institutions. We investigated course structures for elements of a CURE and student outcomes including student knowledge, student learning, student attitudes, interest in future research, overall experience, future GPA, and retention in STEM. We also disaggregated the data to investigate whether underrepresented minority (URM) outcomes were different from White and Asian students. We found that the less time students spent in the CURE the less the course was reported to contain experiences indicative of a CURE. The cCURE imparted the largest impacts for experimental design, career interests, and plans to conduct future research, while the remaining outcomes were similar between the three conditions. The mCURE student outcomes were similar to control courses for most outcomes measured in this study. However, for experimental design, the mCURE was not significantly different than either the control or cCURE. Comparing URM and White/Asian student outcomes indicated no difference for condition, except for interest in future research. Notably, the URM students in the mCURE condition had significantly higher interest in conducting research in the future than White/Asian students.

Abstract
To frame their work, biology education researchers need to consider the role of literature reviews, theoretical frameworks, and conceptual frameworks as critical elements of the research and writing process. However, these elements can be confusing for scholars new to education research. This Research Methods article is designed to provide an overview of each of these elements and delineate the purpose of each in the educational research process. We describe what biology education researchers should consider as they conduct literature reviews, identify theoretical frameworks, and construct conceptual frameworks. Clarifying these different components of educational research studies can be helpful to new biology education researchers and the biology education research community at large in situating their work in the broader scholarly literature.

Abstract
Infusing undergraduate curricula with authentic research training is an important contemporary challenge. Such exposure typically occurs through mentored research (MR) or course-based undergraduate research experiences (CUREs). In Asian contexts, CURE implementation is rare, while MR is often a graduation requirement. In this study, mentor interviews and mentee focus groups were used to characterize the learning challenges associated with this requirement at a Chinese university. An intensive 6-week CURE was then implemented as an MR preparatory program to help mitigate the identified challenges. This program contained seven site-specific features not typically included in other CUREs, each designed to improve different aspects of student readiness for MR. Post-CURE surveys, focus groups, and interviews demonstrated CURE enrollment significantly improved subsequent MR outcomes. Almost 90% of all enrollees, for example, began their first MR experience in their second year, more than twice the rate of non-enrollees. Enrollees also reported greater confidence in their research skills and more frequent experiences working in multiple labs. This study reports both immediate CURE and downstream MR outcomes, using the former to help explain the latter. A comprehensive CURE implementation process is described, offering a potential model for the design of other programs with similar research enhancement goals.

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
Undergraduate students interact with the culture of scientific research when they participate in direct mentorship experiences and laboratory courses such as course-based undergraduate research experiences (CUREs). Much work has been done to explore how CUREs impact the interest, motivation, and retention of undergraduate students in science. However, little work has been done exploring students' experiences and perceptions of the culture of scientific research in the CURE context, and how different CURE models representing different subfields of science impact these experiences and perceptions. This study explored which cultural aspects of scientific research students experienced after participating in a CURE and whether their perceptions of those cultural aspects differed based on students' participation in a bench-based or computer-based research project. Students discussed the Practices and Norms/Expectations of scientific research most frequently. Students in the bench-based and computer-based project areas mentioned different cultural aspects as important to their experiences. Bench-based and computational students also had different perceptions of some of the same cultural aspects, including Teamwork, Freedom & Independence, and Persistence & Resilience. These results suggest that different CURE models differentially impact students' experiences and perceptions of the culture of scientific research, which has implications for examining how students move into scientific research.

Abstract
Objectives We aim to build a students' own engagement in original microbiological course-based undergraduate research experience (CUREs) model served two research and teaching scientific purposes including students' scientific literacy skills and instructors' role, which could further be applied as contribution to broader scientific knowledge and conduct novel research in their future research experience and careers. Methods We describe a student-driven CUREs model on the microorganism species in female vaginal using general bacterial culture techniques and high-throughput 16S rRNA gene amplicon sequencing to enable students to center experimental research method under the direction of instructors. A total of 8 undergraduate students and 5 instructors from Shanghai Jiao Tong University School of Medicine participated in the project. The CUREs were divided in four operating scopes: project planning, implementation, summarizing and feedback phases. Instructors help students to develop learning research goals. Results This project helped students to gain “hard skills” experiences in scientific theoretical research process and technical practices. Students reached the conclusion that Lactobacillus species dominated the primary vaginal microbiota in reproductive-age women, 16S rRNA sequencing is a method widely applied for microbiology detection. CUREs also increased students' engagement in scientific experiments and promote 3 learning goals in “soft skills”: (1) Develop students' self-study and efficacy ability, expression capability and professional research communication skills; (2) Strengthen students' motivation and ownership in science research, overcoming failure, benefitting persistence and patience, building professional science identity, competence, and confidence in collaboration, implement spirit of rigorous and carefulness; (3) Obtain authorship, independent and logical thinking capability, summarizing ability and confidence enhancement. Instructors proposed guiding research question for the students and determine evidence in achieving pedagogical goals in CUREs. Conclusions Our microbiological CUREs project served two scientific purposes: research and teaching, which increase students' engagement in promoting learning gains in scientific research skills, ownership, identity development, and spirit of motivation, self-efficacy, persistence, collaboration, communication, as well as opportunities to make relevant scientific discoveries. These abilities equipped them with essential foundation for the subsequent collaborative experiments and future scientific study.

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 COVID-19 pandemic prompted a transition to remote delivery of courses that lack immersive hands-on research experiences for undergraduate science students, resulting in a scientific research skills gap. In this report, we present an option for an inclusive and authentic, hands-on research experience that all students can perform off-campus. Biology students in a semester-long (13 weeks) sophomore plant physiology course participated in an at-home laboratory designed to study the impacts of nitrogen addition on growth rates and root nodulation by wild nitrogen-fixing Rhizobia in Pisum sativum (Pea) plants. This undergraduate research experience, piloted in the fall semester of 2020 in a class with 90 students, was created to help participants learn and practice scientific research skills during the COVID-19 pandemic. Specifically, the learning outcomes associated with this at-home research experience were: (1) generate a testable hypothesis, (2) design an experiment to test the hypothesis, (3) explain the importance of biological replication, (4) perform meaningful statistical analyses using R, and (5) compose a research paper to effectively communicate findings to a general biology audience. Students were provided with an at-home laboratory kit containing the required materials and reagents, which were chosen to be accessible and affordable in case students were unable to access our laboratory kit. Students were guided through all aspects of research, including hypothesis generation, data collection, and data analysis, with video tutorials and live virtual sessions. This at-home laboratory provided students an opportunity to practice hands-on research with the flexibility to collect and analyze their own data in a remote setting during the COVID-19 pandemic. This, or similar laboratories, could also be used as part of distance learning biology courses.

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
Optimal integration of education and ongoing faculty research in many undergraduate science programs is limited to the capstone project. Here, we aimed to develop a novel course-based undergraduate research experience (CURE) in synergy with ongoing faculty research. This 10-week course called Biomedical Research Lab is embedded in the curriculum of the undergraduate program Biomedical Sciences and grounded in the theoretical framework of research-based learning. Four groups of four students work together in a dedicated laboratory on an actual ongoing research problem of faculty. All groups work on the same research problem, albeit from different (methodological) perspectives, thereby stimulating interdependence between all participants. Students propose new research, execute the experiments, and collectively report in a single research article. According to students, the course enhanced scientific, laboratory, and academic skills. Students appreciated ownership and responsibilities of the research, laboratory teachers as role models, and they were inspired and motivated by doing authentic actual research. The course resulted in a better understanding of what doing research entails. Faculty valued the didactical experience, research output and scouting opportunities. Since topics can change per course edition, we have showcased a widely applicable pedagogy creating synergy between ongoing research and undergraduate education.

Abstract
Course-based undergraduate research experiences (CUREs) engage students in authentic research experiences in a course format and can sometimes result in the publication of that research. However, little is known about student-author perceptions of CURE publications. In this study, we examined how students perceive they benefit from authoring a CURE publication and what they believe is required for authorship of a manuscript in a peer-reviewed journal. All 16 students who were enrolled in a molecular genetics CURE during their first year of college participated in semistructured interviews during their fourth year. At the time of the interviews, students had been authors of a CURE publication for a year and a half. Students reported that they benefited personally and professionally from the publication. Students had varying perceptions of what is required for authorship, but every student thought that writing the manuscript was needed, and only two mentioned needing to approve the final draft. Additionally, we identified incomplete conceptions that students had about CURE publications. This work establishes student-perceived benefits from CURE publications and highlights the need for authorship requirements to be explicitly addressed in CUREs.

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.

JOURNAL OF MICROBIOLOGY & BIOLOGY EDUCATION 2021; 22:jmbe00156-21. [PMID: 34594446 PMCID: PMC8442013 DOI: 10.1128/jmbe.00156-21] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/20/2021] [Accepted: 04/21/2021] [Indexed: 06/13/2023]
Abstract
Undergraduate research plays an important role in the development of science students. The two most common forms of undergraduate research are those in traditional settings (such as internships and research-for-credit in academic research labs) and course-based undergraduate research experiences (CUREs). Both of these settings offer many benefits to students, yet they have unique strengths and weaknesses that lead to trade-offs. Traditional undergraduate research experiences (UREs) offer the benefits of personalized mentorship and experience in a professional setting, which help build students' professional communication skills, interest, and scientific identity. However, UREs can reach only a limited number of students. On the other end of the trade-off, CUREs offer research authenticity in a many-to-one classroom research environment that reaches more students. CUREs provide real research experience in a collaborative context, but CUREs are not yet necessarily equipping students with all of the experiences needed to transition into a research lab environment outside the classroom. We propose that CURE instructors can bridge trade-offs between UREs and CUREs by deliberately including learning goals and activities in CUREs that recreate the benefits of UREs, specifically in the areas of professional communication, scientific identify, and student interest. To help instructors implement this approach, we provide experience- and evidence-based guidance for student-centered, collaborative learning opportunities.

Abstract
Course-based undergraduate research experiences (CUREs) provide students with opportunities for the same gains that apprenticed research with faculty members offers. As their popularity increases, it is important that critical elements of CUREs be supported by thoughtful design. Student experiences in CUREs can provide important insights into why CUREs are so effective. We present evidence from students who participated in CUREs at the introductory, intermediate, and advanced levels, as well as from graduate teaching assistants for an introductory lab course that included a CURE. Students and teaching assistants describe repetition as a valuable element in CUREs and other laboratory experiences. We used student work and open-ended interviews to identify which of five previously described elements of CUREs students found important. Because repetition was particularly salient, we characterized how students described repetition as they experienced it in courses that contained full-length CUREs or "micro-CUREs." In prompted interviews, students described how repetition in CUREs provided cognitive (learning concepts) and practical (learning technical skills) value. Recent graduates who had participated in CUREs at each level of their biology education were particularly aware that they placed value on repetition and acknowledged it as motivational in their own learning. Many students described repetition in metacognitive terms, which also suggests that as students advance through laboratory and CURE curricula, their understanding of how repetition supports their learning becomes more sophisticated. Finally, we integrated student descriptions to suggest ways in which repetition can be designed into CUREs or other laboratory courses to support scientific learning and enhance students' sense of scientific identity.

Abstract
We have developed and implemented an undergraduate microbiology course in which students isolate, characterize, and perform whole genome assembly and analysis of Salmonella enterica from stream sediments and poultry litter. In the development of the course and over three semesters, successive teams of undergraduate students collected field samples and performed enrichment and isolation techniques specific for the detection of S. enterica. Eighty-eight strains were confirmed using standard microbiological methods and PCR of the invA gene. The isolates' genomes were Illumina-sequenced by the Center for Food Safety and Applied Nutrition at the FDA and the Virginia state Division of Consolidated Laboratory Services as part of the GenomeTrakr program. Students used GalaxyTrakr and other web- and non-web-based platforms and tools to perform quality control on raw and assembled sequence data, assemble, and annotate genomes, identify antimicrobial resistance and virulence genes, putative plasmids, and other mobile genetic elements. Strains with putative plasmid-borne antimicrobial resistance genes were further sequenced by students in our research lab using the Oxford Nanopore MinIONTM platform. Strains of Salmonella that were isolated include human infectious serotypes such as Typhimurium and Infantis. Over 31 of the isolates possessed antibiotic resistance genes, some of which were located on large, multidrug resistance plasmids. Plasmid pHJ-38, identified in a Typhimurium isolate, is an apparently self-transmissible 183 kb IncA/C2 plasmid that possesses multiple antimicrobial resistance and heavy-metal resistance genes. Plasmid pFHS-02, identified in an Infantis isolate, is an apparently self-transmissible 303 kb IncF1B plasmid that also possesses numerous heavy-metal and antimicrobial resistance genes. Using direct and indirect measures to assess student outcomes, results indicate that course participation contributed to cognitive gains in relevant content knowledge and research skills such as field sampling, molecular techniques, and computational analysis. Furthermore, participants self-reported a deeper interest in scientific research and careers as well as psychosocial outcomes (e.g., sense of belonging and self-efficacy) commonly associated with student success and persistence in STEM. Overall, this course provided a powerful combination of field, wet lab, and computational biology experiences for students, while also providing data potentially useful in pathogen surveillance, epidemiological tracking, and for the further study of environmental reservoirs of S. enterica.

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
We seek to increase student engagement and success to subsequently lead to increased retention and degree attainment for students at our Hispanic-serving institution. We hypothesized that using a culturally responsive approach in an undergraduate microbiology lab would increase engagement and learning gains. Using a culturally responsive approach allowed students to start their learning from their own place of understanding-centering students' lived experiences. Students interviewed family members to learn about "home remedies," and then devised experiments to test whether those home remedies affected growth of bacteria commonly implicated in gastrointestinal distress (Staphylococcus aureus, Bacillus cereus, and Escherichia coli) or sore throat (Neisseria gonorrhoeae, Streptococcus pyogenes, and Mycoplasma pneumoniae). As a final assessment, students generated project posters which they presented at a class symposium. Implementation of a culturally responsive research experience focused on the gut microbiome resulted in increased learning gains as evidenced by movement up Bloom's Revised Taxonomy Scale. Student feedback indicated increased engagement, increased confidence in communicating science and a deeper understanding and appreciation for microbiology. Taken together, the results indicate that students appreciate a more culturally responsive and student-centered approach to learning in microbiology and encourages expansion of this approach to other modules in the course. This paper includes responsive data to support this claim, as well as a sample course calendar and supplementary learning material to support the human microbiome approach to microbiology.

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.

Abstract
Microbiome research projects are often interdisciplinary, involving fields such as microbiology, genetics, ecology, evolution, bioinformatics, and statistics. These research projects can be an excellent fit for undergraduate courses ranging from introductory biology labs to upper-level capstone courses. Microbiome research projects can attract the interest of students majoring in health and medical sciences, environmental sciences, and agriculture, and there are meaningful ties to real-world issues relating to human health, climate change, and environmental sustainability and resilience in pristine, fragile ecosystems to bustling urban centers. In this review, we will discuss the potential of microbiome research integrated into classes using a number of different modalities. Our experience scaling-up and implementing microbiome projects at a range of institutions across the US has provided us with insight and strategies for what works well and how to diminish common hurdles that are encountered when implementing undergraduate microbiome research projects. We will discuss how course-based microbiome research can be leveraged to help faculty make advances in their own research and professional development and the resources that are available to support faculty interested in integrating microbiome research into their courses.

Abstract
Support for undergraduate laboratory education based on a CURE (Course-based Undergraduate Research Experience) model is more widespread than ever. By giving students the opportunity to conduct genuine research in laboratory courses they are required to take, CUREs can expose more students to scientific practice and have the potential to make science more inclusive, especially when research topics have direct impact on students' lives. Here, I present a new microbiology CURE module where students explore the real-world intersection between industrial food production and the human microbiome. In this module, students sequence CRISPR arrays in the genomes of lactic acid bacteria they isolate from yogurt. Natural CRISPRs (Clustered Regularly Interspaced Short Palindromic Repeats) act as the bacterial immune system. When a bacterial cell survives viral infection, it can incorporate a bit of that virus's DNA into its own genome, and produce small RNA guides that surveil the cell, ready to deploy virus-destroying enzymes if matching DNA from a fresh viral infection is detected. This viral immunity is of particular interest in the fermentation industry, since viral infection can destroy stocks of starter cultures and batches of product. Commercial producers of lactic acid bacteria for yogurt production often endeavor to produce strains with large CRISPR arrays and robust immunities. With this context, students are given the task of cataloging the viral immunities found in both commercial and traditionally produced yogurt, and exploring their potential impact on human health. Wet-lab practices (strain isolation, PCR, and Sanger sequencing) are combined with bioinformatic and literature sleuthing to identify the viruses to which bacteria are immune and explore whether consumption of these strains could impact human health via interactions with the human microbiome. Here, a detailed implementation of the module is presented with guides for educators and students.

Abstract
Today's rapidly changing world calls for sustainability-minded scientists who are prepared to solve complex, interconnected problems. Service learning is a pedagogical approach that allows students to engage with the needs of the community by integrating academic work with complex civic issues. Student learning was examined during a short-term service-learning experience focused on water-quality monitoring in an urban watershed to determine whether community-engaged fieldwork in an upper-level ecology lab course enhances sustainability knowledge for future biologists. We used concept map scoring methods and reflection assessments to evaluate and understand changes in the structure and content of student knowledge as a result of the experience. Students showed increases in sustainability knowledge breadth, depth, and complexity, particularly in demonstrating biological-sociological connections. Student reflections indicated most students identified at least one community-engaged serving-learning objective as a result of this experience. These results suggest that community-engaged fieldwork can illustrate ecological and sociological sustainability concepts for students and that engagement works best when we make explicit our objective of engaging communities in the learning process. Short service-learning experiences are effective, can be quickly assessed using concept maps, and can be readily incorporated in other classrooms to enhance sustainability education.

Abstract
Depression is a top mental health concern among undergraduates and has been shown to disproportionately affect individuals who are underserved and underrepresented in science. As we aim to create a more inclusive scientific community, we argue that we need to examine the relationship between depression and scientific research. While studies have identified aspects of research that affect graduate student depression, we know of no studies that have explored the relationship between depression and undergraduate research. In this study, we sought to understand how undergraduates' symptoms of depression affect their research experiences and how research affects undergraduates' feelings of depression. We interviewed 35 undergraduate researchers majoring in the life sciences from 12 research-intensive public universities across the United States who identify with having depression. Using inductive and deductive coding, we identified that students' depression affected their motivation and productivity, creativity and risk-taking, engagement and concentration, and self-perception and socializing in undergraduate research experiences. We found that students' social connections, experiencing failure in research, getting help, receiving feedback, and the demands of research affected students' depression. Based on this work, we articulate an initial set of evidence-based recommendations for research mentors to consider in promoting an inclusive research experience for students with depression.

Abstract
Course-based undergraduate research experiences (CUREs) are an effective way to expose large numbers of students to authentic research, yet most laboratory courses still use traditional "cookbook" methods. While barriers to using CUREs have been captured postimplementation, little is known about the decision mindset before implementation or what features of CURE design may mitigate perceived barriers. Perception of an innovation (such as a CURE) influences the likelihood of its adoption, and diffusion of innovations theory posits that the decision to adopt is largely influenced by five perceived features of an innovation: relative advantage, compatibility, complexity, observability, and trialability. We conducted interviews with instructors considering using the Prevalence of Antibiotic Resistance in the Environment (PARE) project to assess their perceptions of CUREs and motivations for using PARE. Instructors viewed CUREs as having relative advantages over traditional methods; however, CUREs were also viewed as complex, with instructors citing multiple barriers. Instructors were motivated to use PARE because of its potential scientific impact and compatibility with their courses' structures and resources. Instructors perceived PARE to have few barriers to implementation compared with other CUREs. Designing CUREs that address common instructor barriers and drivers could increase the rate of diffusion of CUREs.

Abstract
While it has been established that course-based undergraduate research experiences (CUREs) lead to student benefits, it is less clear what aspects of CUREs lead to such gains. In this study, we aimed to understand the effect of students analyzing their own data, compared with students analyzing data that had been collected by professional scientists. We compared the experiences of students in a CURE investigating whether the extinction risk status of terrestrial mammals and birds is associated with their ecological traits. Students in the CURE were randomly assigned to analyze either data that they had collected or data previously collected by professional scientists. All other aspects of the student experience were designed to be identical. We found that students who analyzed their own data showed significantly greater gains in scientific identity and emotional ownership than students who analyzed data collected by professional scientists.
