DNA at the whim of the water: environmental DNA as a course-based undergraduate research experience

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.

Identifying new small proteins through a molecular biology course-based undergraduate research experience laboratory class

We developed a curriculum for an upper-level molecular biology course-based undergraduate research laboratory class funded by a National Science Foundation CAREER grant that focuses on identifying new small proteins in the bacterium, Escherichia coli. Our CURE class has been continually offered each semester for the last 10 years, with multiple instructors collaboratively developing and implementing their own pedagogical approach while maintaining the same overall scientific goal and experimental strategy. In this paper, we delineate the experimental strategy for our molecular biology CURE laboratory class, describe a range of pedagogical approaches implemented by multiple instructors, and provide recommendations for teaching the class. The purpose of our paper is to share our experiences both in developing and teaching a molecular biology CURE laboratory class based on small protein identification and in creating a curriculum and support system that allows traditional, non-traditional, and under-represented students to participate in authentic research projects.

Science communication from a course-based undergraduate research experience

Course-based undergraduate research experiences (CUREs) provide an efficient mechanism to provide many students with an original research project. CUREs often culminate in a capstone poster presentation, but reports on these classes usually focus on the preparation and execution of the project rather than communication of the results. This article summarizes a CURE-associated research seminar that focuses on developing the communication and interpersonal skills required for the production and presentation of a conference poster. The class is designed to provide students with the tools and confidence for effective communication of their research. From the two class offerings to date, the 18 participating students have received five awards from 19 conference presentations.

SMART CUREs: a Professional Development Program for Advancing Teaching Assistant Preparedness To Facilitate Course-Based Undergraduate Research Experiences

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.

Can We Quantify If It's a CURE?

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.

Converting a face-to-face neuroanatomy course-based undergraduate research experience (CURE) to an online environment: lessons learned from remote teaching

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.

A participatory study of college students' mental health during the first year of the COVID-19 pandemic

Introduction

The COVID-19 pandemic has negatively impacted college students' mental health and wellbeing. Even before the pandemic, young adults reported high mental health morbidity. During the pandemic, young adult college students faced unprecedented challenges, including campus closure and a pivot to fully online education.

Methods

This study employed a novel participatory approach to a Course-based Undergraduate Research Experience (CURE) in an introductory epidemiology course to examine factors students considered important regarding their experience during the pandemic. Two groups of undergraduate students enrolled in this course (one in Fall 2020 and another in Spring 2021) and participated in the CURE. A sub-group of these students continued after the class and are authors of this article. Through repeated cross-sectional surveys of college students' peer groups in northern California in October 2020 and March 2021, this student/faculty collaborative research team evaluated depression, anxiety, suicidal ideation and several other topics related to mental health among the students' young adult community.

Results

There was a high prevalence of anxiety (38.07% in October 2020 and 40.65% in March 2021), depression (29.85% in October 2020 and 27.57% in March 2021), and suicidal ideation (15.94% in October 2020 and 16.04% in March 2021). In addition, we identified the significant burden of loneliness for college students, with 58.06% of students reporting feeling lonely at least several days in the past two weeks. Strategies that students used to cope with the pandemic included watching shows, listening to music, or playing video games (69.01%), sleeping (56.70%), taking breaks (51.65%), and connecting with friends (52.31%) or family (51.21%). Many reported distressing household experiences: more than a third reporting loss of a job or income (34.27%) in the first year of the pandemic. We explain the participatory research approach and share empirical results of these studies.

Discussion

We found this participatory CURE approach led to novel, experience-based research questions; increased student motivation; real-world benefits such as combatting imposter syndrome and supporting graduate school intentions; integration of teaching, research, and service; and development of stronger student-faculty relationships. We close with recommendations to support student wellbeing and promote student engagement in research.

From genetics to biotechnology: Synthetic biology as a flexible course-embedded research experience

The need for changing how science is taught and the expansion of undergraduate research experiences is essential to foster critical thinking in the Natural Sciences. Most faculty research programs only involve a small number of upper-level undergraduate students each semester. The course-based undergraduate research experience (CURE) model enables more students to take ownership over an independent project and experience authentic research. Further, by creating projects that fit into a curriculum's learning goals and student-oriented outcomes, departments help strengthen critical thinking skills in the classroom. Here, we report on the incorporation of a synthetic biology CURE into a mid-level cellular biology course and two advanced level genetics/molecular biology courses. Synthetic biology involves systematic engineering of novel organisms, such as bacteria and plants, to work as functional devices to solve problems in medicine, agriculture, and manufacturing. The value of synthetic biology and its ultimate utility as a teaching tool relies on reusable, standard genetic parts that can be interchanged using common genetic engineering principles. This Synthetic biology CURE effectively achieves five essential goals: (1) a sense of project ownership; (2) self-efficacy: mastery of a manageable number of techniques; (3) increased tolerance for obstacles through challenging research; (4) increased communication skills; and (5) a sense of belonging in a larger scientific community. Based upon our student assessment data, we demonstrate that this course-based synthetic biology laboratory engages students directly in an authentic research experience and models important elements of collaboration, discovery, iteration, and critical thinking.

A CURE for Physiological Characterization of Bacterioplankton in Liquid Culture

Bacterial characterization is an important aspect of microbiology that includes experimentally determining growth rates, environmental conditions conducive to growth, and the types of energy sources microorganisms can use. Researchers use this information to help understand and predict an organism's ecological distribution and environmental functions. Microbiology students generally conduct bacterial characterization experiments in their coursework; however, they are frequently restricted to model organisms without ecological relevance and already well-studied physiologies. We present a course-based undergraduate research experience (CURE) curriculum to involve students in characterization of previously untested, ecologically relevant aquatic free-living bacteria (bacterioplankton) cultures to identify the usable nutrient substrates, as well as the temperature and salinity ranges conducive to growth. Students use these results to connect their organism's physiology to the isolation environment. This curriculum also exposes students to advanced microbiology methods such as flow cytometry for measuring cell concentrations, teaches them to use the programming language R for data plotting, and emphasizes scientific communication through writing, speaking, poster creation/presentation, and social media. This CURE is an attractive introduction to scientific research and was successfully tested with 187 students in three semesters at two different universities. Students generated reproducible growth data for multiple strains across these different deployments, demonstrating the utility of the curriculum for research support.

A CURE for the COVID-19 Era: A Vaccine-Focused Online Immunology Laboratory

During the COVID-19 pandemic, universities across the globe quickly shifted to online education. Laboratory courses faced unique challenges and were forced to reevaluate learning objectives and identify creative projects to engage students online. This study describes a newly developed online immunology laboratory curriculum focused on vaccine development. The course incorporated learning objectives to teach the scientific process, key experimental design components, and immunology techniques to evaluate vaccine efficacy. The curriculum, a course-based undergraduate research experience (CURE), asked students to engage in the research literature, propose a vaccine design and assessment, and interpret mock results. Instructor evaluation of student work as well as student self-evaluations demonstrated that students met the curriculum's learning objectives. Additionally, results from the laboratory course assessment survey (LCAS) indicate that this curriculum incorporated the CURE elements of collaboration, discovery and relevance, and iteration.

Addressing Foodborne Illness in Côte d'Ivoire: Connecting the Classroom to the Community through a Nonmajors Course-Based Undergraduate Research Experience

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.

Keeping Students Connected and Engaged in a Wet-Lab Research Experience during a Time of Social Distancing via Mobile Devices and Video Conferencing Software

Two major COVID-19 pandemic challenges presented for in-person instruction included adhering to social distancing guidelines and accommodating remote learners who were temporarily isolated or permanently participating from afar. At Binghamton University, our First-year Research Immersion (FRI) program was challenged with providing students with a wet lab course-based undergraduate research experience (CURE), an intense hands-on experience that emphasized student teamwork, lab protocol development, iteration, troubleshooting, and other elements of the scientific process that could not be replicated in a fully remote environment. We developed an innovative technology approach to maximize all students' connection to the lab research experience, utilizing dedicated mobile devices (iPod Touch) and video conferencing software (Zoom) to synchronously connect remote learners to in-person learners, peer mentors, and instructors in our FRI research labs. In this way, despite limited lab capacities and fluctuating remote learning populations, we were able to connect remote learners to their peers and mentors in real-time and give them responsibilities that allowed them to be engaged and feel like meaningful participants in the research process. Although our students reported a preference for in-person labs, they noted that this hybrid model was better than other traditionally employed remote-learning lab options. We believe that the lessons learned here can be applied to improve access to research in all situations and allow us to be prepared for other catastrophic disruptions to the educational system.

TikTok: An Emergent Opportunity for Teaching and Learning Science Communication Online

Increasing use of social media during the COVID-19 pandemic practice of social distancing has emphasized the value and power of effective science communication through social media. As such, it has become equally important to teach and learn how to use social media accurately and effectively for science communication. In response, we developed an activity to use the social media platform TikTok to both model and build effective 21st century science communication skills. TikTok is a short-form video sharing platform whose popularity sharply increased during the COVID-19 pandemic. By using the short, focused video style of TikTok, we modeled effective social media science communication practices to teach basic science concepts and laboratory techniques. At the end of the semester, students were then challenged to create their own informative and engaging TikToks about their team's research projects to practice effective science communication. Here we share our approach and several TikTok best practices for effective and engaging science communication teaching and learning, along with example videos created during this process.

The DoC IT: a Professional Development Tool to Support and Articulate Alignment of One's Course with the Five Dimensions of CUREs

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.

A Course-Based Undergraduate Research Experience in CRISPR-Cas9 Experimental Design to Support Reverse Genetic Studies in Arabidopsis thaliana

Gene-editing tools such as CRISPR-Cas9 have created unprecedented opportunities for genetic studies in plants and animals. We designed a course-based undergraduate research experience (CURE) to train introductory biology students in the concepts and implementation of gene-editing technology as well as develop their soft skills in data management and scientific communication. We present two versions of the course that can be implemented with twice-weekly meetings over a 5-week period. In the remote-learning version, students performed homology searches, designed guide RNAs (gRNAs) and primers, and learned the principles of molecular cloning. This version is appropriate when access to laboratory equipment or in-person instruction is limited, such as during closures that have occurred in response to the COVID-19 pandemic. In person, students designed gRNAs, cloned CRISPR-Cas9 constructs, and performed genetic transformation of Arabidopsis thaliana. Students learned how to design effective gRNA pairs targeting their assigned gene with an 86% success rate. Final exams tested students' ability to apply knowledge of an unfamiliar genome database to characterize gene structure and to properly design gRNAs. Average final exam scores of ∼73% and ∼84% for in-person and remote-learning CUREs, respectively, indicated that students met learning outcomes. The highly parallel nature of the CURE makes it possible to target dozens to hundreds of genes, depending on the number of sections. Applying this approach in a sensitized mutant background enables focused reverse genetic screens for genetic suppressors or enhancers. The course can be adapted readily to other organisms or projects that employ gene editing.

Agar Art: a CURE for the Microbiology Laboratory

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.

Student Outcomes From a Large-Enrollment Introductory Course-Based Undergraduate Research Experience on Soil Microbiomes

In recent years, national reports have called for undergraduate laboratory education that engages students in authentic research experiences. As a result, a number of course-based undergraduate research experiences (CUREs) have been developed in biological sciences and some specifically in microbiology. Students benefit from CUREs much like in traditional mentored research experiences, where students carry out independent projects in faculty laboratories. These benefits include increased self-efficacy in research skills, enhanced identification as scientists, and higher graduation rates in science, technology, engineering, and mathematics majors. Because mentored research experiences are not readily available to every student, CUREs represent a potential mechanism to democratize the research experience by providing such opportunities to all students. However, many of existing CUREs described in the literature are designed for advanced undergraduates or are limited to a small number of students. Here, we report student outcomes from a large-enrollment introductory CURE on soil microbiomes that engages students in a real-world context with microbiology. In pre- and post-course surveys, students reported significant gains in self-efficacy on a number of research skills. These results are triangulated with post-course survey data on project ownership, sense of community, and CURE design elements such as collaboration, iteration, discovery, and relevance.

CUREing cancer: Development and implementation of a molecular biology-focused course-based undergraduate research experience using a cancer cell culture model

Many students in the sciences are interested in exploring research opportunities; however, the one-on-one faculty mentorship model often lacks the ability to supervise large numbers of students. An alternative mechanism for exposing undergraduate students to the research process is participation in a Course-based Undergraduate Research Experience (CURE). CUREs promote inclusivity in research, and provide structure for both students and faculty while engaging students in scientific discovery. This study describes a model for a CURE in cancer biology, and reports student outcomes. Students utilized bioinformatics to predict targets genes of miR-100, a microRNA that is differentially expressed in a cell culture model of breast cancer metastasis. Students were required to engage with primary literature to write a grant proposal for their target gene, and then were trained to perform basic molecular biology techniques to test their individual hypotheses. Additionally, the course integrated opportunities to troubleshoot experiments and present data to the group, and culminated in a publication style scientific report discussing the results of their individual research project. Students reported significantly increased confidence in executing various molecular biology techniques and research-related skills based on pre- and post-assessment surveys. Student feedback also indicated that they gained an understanding of primary literature, experimental design, and scientific writing as a result of the course. This study supports that CUREs can be an effective pedagogy for not only engaging larger groups of students in research, but also improving their confidence and skill set in the laboratory.

Propelling a Course-Based Undergraduate Research Experience Using an Open-Access Online Undergraduate Research Journal

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.

Is Community Relevance Enough? Civic and Science Identity Impact of Microbiology CUREs Focused on Community Environmental Justice

Course-based undergraduate research experiences (CUREs) often involve a component where the outcomes of student research are broadly relevant to outside stakeholders. We wanted to see if building courses around an environmental justice issue relevant to the local community would impact students' sense of civic engagement and appreciation of the relevance of scientific research to the community. In this quasi-experimental study, we assessed civic engagement and scientific identity gains (N = 98) using pre- and post-semester surveys and open-ended interview responses in three different CUREs taught simultaneously at three different universities. All three CURES were focused on an environmental heavy metal pollution issue predominantly affecting African-Americans in Birmingham, Alabama. While we found increases in students' sense of science efficacy and identity, our team was unable to detect meaningful changes in civic engagement levels, all of which were initially quite high. However, interviews suggested that students were motivated to do well in their research because the project was of interest to outside stakeholders. Our observations suggest that rather than directly influencing students' civic engagement, the "broadly relevant" component of our CUREs engaged their pre-existing high levels of engagement to increase their engagement with the material, possibly influencing gains in science efficacy and science identity. Our observations are consistent with broader community relevance being an important component of CURE success, but do not support our initial hypothesis that CURE participation would influence students' attitudes toward the civic importance of science.

Cognitive and Non-Cognitive Outcomes Associated with Student Engagement in a Novel Brain Chemoarchitecture Mapping Course-Based Undergraduate Research Experience

Course-based undergraduate research experiences (CUREs) engage emerging scholars in the authentic process of scientific discovery, and foster their development of content knowledge, motivation, and persistence in the science, technology, engineering, and mathematics (STEM) disciplines. Importantly, authentic research courses simultaneously offer investigators unique access to an extended population of students who receive education and mentoring in conducting scientifically relevant investigations and who are thus able to contribute effort toward big-data projects. While this paradigm benefits fields in neuroscience, such as atlas-based brain mapping of nerve cells at the tissue level, there are few documented cases of such laboratory courses offered in the domain. Here, we describe a curriculum designed to address this deficit, evaluate the scientific merit of novel student-produced brain atlas maps of immunohistochemically-identified nerve cell populations for the rat brain, and assess shifts in science identity, attitudes, and science communication skills of students engaged in the introductory-level Brain Mapping and Connectomics (BM&C) CURE. BM&C students reported gains in research and science process skills following participation in the course. Furthermore, BM&C students experienced a greater sense of science identity, including a greater likelihood to discuss course activities with non-class members compared to their non-CURE counterparts. Importantly, evaluation of student-generated brain atlas maps indicated that the course enabled students to produce scientifically valid products and make new discoveries to advance the field of neuroanatomy. Together, these findings support the efficacy of the BM&C course in addressing the relatively esoteric demands of chemoarchitectural brain mapping.

A modular laboratory course using planarians to study genes involved in tissue regeneration

Undergraduate research experiences are excellent opportunities to engage students in science alongside experienced scientists, but at large institutions, it is challenging to accommodate all students. To address and engage a larger number of students, we developed a modular laboratory course based on the course-based undergraduate research experiences model. This new course was integrated with the scientific aims of a research laboratory studying the cellular and molecular mechanisms underlying tissue regeneration in planarians. In this course, students were asked to identify genes with roles in planarian biology. Students analyzed and cloned an assigned gene, determined its expression pattern in situ and examined its function in regeneration. Additionally, we developed critical thinking and scientific communication skills by incorporating activities focused on critical concepts. Students obtained high quality primary data and were successful in completing and mastering the course learning outcomes. They benefitted by developing basic research skills, learning to perform, trouble-shooting experiments, reading and critically analyzing primary literature, and using the information to defend and explain their experimental results. Through this course, students also increased their confidence and ability to perform independent scientific research. The course was designed to make it accessible to the community to implement and adapt as appropriate in diverse institutions. © 2019 International Union of Biochemistry and Molecular Biology, 47(5):547-559, 2019.

Aptamers in Education: Undergraduates Make Aptamers and Acquire 21st Century Skills Along the Way

Aptamers have a well-earned place in therapeutic, diagnostic, and sensor applications, and we now show that they provide an excellent foundation for education, as well. Within the context of the Freshman Research Initiative (FRI) at The University of Texas at Austin, students have used aptamer selection and development technologies in a teaching laboratory to build technical and 21st century skills appropriate for research scientists. One of the unique aspects of this course-based undergraduate research experience is that students develop and execute their own projects, taking ownership of their experience in what would otherwise be a traditional teaching lab setting. Of the many successes, this work includes the isolation and characterization of novel calf intestinal alkaline phosphatase (anti-CIAP) RNA aptamers by an undergraduate researcher. Further, preliminary survey data suggest that students who participate in the aptamer research experience express significant gains in their self-efficacy to conduct research, and their perceived ability to communicate scientific results, as well as organize and interpret data. This work describes, for the first time, the use of aptamers in an educational setting, highlights the positive student outcomes of the aptamer research experience, and presents the research findings relative to the novel anti-CIAP aptamer.

Interdisciplinary STEM education reform: dishing out art in a microbiology laboratory

In the modern educational framework, life science and visual art are usually presented as mutually exclusive subjects. Despite this perceived disciplinary contrast, visual art has the ability to engage and provoke students in ways that can have important downstream effects on scientific discovery, especially when applied in a practical setting such as a laboratory course. This review broadly examines the benefit of interdisciplinary fusions of science and art as well as recent ways in which art strategies have been used in undergraduate biology classrooms. In a case study, we found that undergraduate students in an introductory microbiology laboratory course who participated in open-inquiry activities involving agar art had greater confidence in their personal efficacy as scientists compared to a control class. Collectively, these observations suggest that visual art can be a useful enhancement in the course-based undergraduate research setting, and science educators at all levels should consider incorporating artistic creativity in their own classroom strategies.

A course-based undergraduate research experience investigating p300 bromodomain mutations

Course-based undergraduate research experiences (CUREs) provide an opportunity for students to engage in experiments with outcomes that are unknown to both the instructor and students. These experiences allow students and instructors to collaboratively bridge the research laboratory and classroom, and provide research experiences for a large number of students relative to traditional individual mentored research. Here, we describe a molecular biology CURE investigating the impact of clinically relevant mutations found in the bromodomain of the p300 transcriptional regulator on acetylated histone interaction. In the CURE, students identified missense mutations in the p300 bromodomain using the Catalogue of Somatic Mutations in Cancer (COSMIC) database and hypothesized the effects of the mutation on the acetyl-binding function of the domain. They cloned and purified the mutated bromodomain and performed peptide pulldown assays to define its potential to bind to acetylated histones. Upon completion of the course, students showed increased confidence performing molecular techniques and reported positively on doing a research project in class. In addition, results generated in the classroom were further validated in the research laboratory setting thereby providing a new model for faculty to engage in both course-based and individual undergraduate research experiences.
