P100 Undergraduate research-based education for identifying new treatment options for cystic fibrosis

Cystic fibrosis (CF) is an autosomal recessive disease were approximately 100.000 cases worldwide, 15% of which cannot be treated. Interdisciplinary collaboration is necessary to solve complex problems like this. To train interdisciplinary collaboration, at Utrecht University bachelor students biomedical sciences and medicine (>100 students) were challenged to brainstorm feasible research proposals for new CF treatments. From this, one proposal was selected to be executed in the undergraduate course, Experimental Translational Medicine. This is an interdisciplinary 10-week research-based course where 16 medicine and biomedical sciences bachelor students execute the best research proposal in a dedicated wet laboratory (Bachelor Research Hub) together with and facilitated by faculty staff, including researchers and medical doctors.

Cross-disciplinary CURE Program Increases Educational Aspirations in a Large Community College.

Undergraduate research experiences have been widely demonstrated as a beneficial and essential component of the college experience. However, many community colleges face barriers and lack of support in implementing such research programs, which means a significant number of community college students miss out on these impactful experiences. Course-based undergraduate research experiences (CUREs) represent a feasible way to increase access to research experiences within community colleges. To investigate whether these CURE opportunities resulted in comparable to 4-year university CURE students, a CURE program was developed across various disciplines in a large community college and the impact on community college students was assessed. Analysis of both qualitative and quantitative data showed that students reported improvement in research skills, increases in confidence, and increases in educational aspirations. Peer interactions and instructor relationships in CUREs were identified as key factors associated with increases in research skills. Key factors associated with increases in educational aspirations included confidence in research-based courses, seeking additional research opportunities, and building a meaningful relationship with the instructor, but only if confidence increased as well. Our findings indicate that CUREs positively impact student outcomes in the community college setting and may provide increased access to research experiences.

Incorporating field-based research into remote learning: An assessment of soil lead pollution in different land-use types in Los Angeles

A research-based course was developed to investigate the legacy of soil lead (Pb) pollution in Los Angeles, California. During the course, undergraduate and graduate students collected a total of 270 soil samples for analyses of metal (loid) concentrations in different land-use types (residential, park, and school). Residential soils had significantly higher Pb concentrations than other land uses (p < 0.01) exceeding the California recommended safety level for soil Pb (80 mg/kg) at the highest frequency (64% of samples), followed by schools (42%) and parks (6.0%). Soil Pb from all 87 census block groups was correlated with battery recycling plant and railroad proximity as geospatial indicators of childhood Pb exposure risk. Meanwhile, census block groups with higher Pb levels were correlated with higher percentages of the following population: those without health insurance, without college degrees, with a lower median household income and income below the poverty line, and ethnic and racial minorities (r = −0.46 to 0.59, p < 0.05). Principal component regression models significantly improved soil Pb estimation over correlation analysis by incorporating sociodemographic, economic, and geospatial risk factors for Pb exposure (R2 = 0.58, p < 0.05). This work provides new insights into how topsoil Pb prevails in various land-use types and their co-occurring sociodemographic, economic, and geospatial risk factors, indicating the need for multi-scalar assessment across urban land uses.

Incorporating collaborative learning in teacher education to foster self-efficacy to implement environmental citizenship: an action research

PurposeEngaging students in environmental citizenship to promote education for sustainability (EfS) as an explicit goal of academic courses is not common, notwithstanding wide consensus on its importance. Collaborative learning has rarely been investigated using action research methods in the context of environmental citizenship in higher education; the purpose of this study is to fill the gap.Design/methodology/approachAdopting Bandura's (2012) theory of self-efficacy and collective efficacy, this study explores how collaborative learning, used throughout an action research-based course, encouraged students’ efficacy to implement environmental citizenship in their communities. Data were collected through multiple sources: students’ written reflections, instructors’ reflective journals and continuous discussions, interviews with students and different documents (course syllabi, lesson plans and students' scientific posters).FindingsThe findings of this study indicate that the authors succeeded in creating an appropriate social academic setting for the students to become acquainted with each other and to share ideas, successes and challenges in an accepting atmosphere, which proved beneficial to developing their self-confidence to promote EfS in practice. Adopting collaborative learning in the context of environmental citizenship also increased students' self-efficacy and collective efficacy. Self-efficacy was strengthened in the four sources discussed by Bandura (2012): mastery experiences, social modeling, social persuasion and emotional states. Collective efficacy was developed both in the academic and practical domains.Originality/valueThe findings of this study suggest that collaborative learning could serve as a powerful way to promote EfS in higher education, especially in teacher education. This contribution was achieved through integrating academic and practical knowledge foundations, which are required to implement environmental citizenship successfully, supporting learners’ initial steps towards becoming change agents in the society.

Students' Emotions, Perceived Coping, and Outcomes in Response to Research-Based Challenges and Failures in Two Sequential CUREs.

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.

Preserving stories, preserving food:

Worldviews, cultures, spirituality, and history not only influence how societies define “food” and “waste”, they also shape how we consume food and the relationship we have with the broader food system. While food waste has emerged as a global concern and a complex “wicked problem” that impacts stakeholders at all scales of operations, the issue is often framed as an environmental and economic problem, and less so as a social problem. As the food waste literature expands at a rapid pace, there is still a dearth of studies that focus on cultural and intergenerational approaches to food preservation and food waste reduction. This exploratory study emerged from an upper-year research-based course entitled Building Sustainable Food Systems (REM 363- now REM 357) at Simon Fraser University and offers three vignettes through intergenerational and multicultural interviews from Siksika First Nation (Canada), Pakistan and China. Students from the class explored the roles of intergenerational storytelling and informal learning by conducting key informant interviews with close relatives to document traditional food preservation techniques. This study created a transformative intergenerational and multicultural bonding opportunity, which allowed students to better understand their relationships to food, culture, and their relatives. The students also documented how the relationship to food has changed over time. Findings from the study suggest that intergenerational storytelling can help reduce food waste by increasing food literacy, improving cultural connections, and raising awareness about alternative worldviews that challenge the commoditization of food.

Integrating CUREs in Ongoing Research: Undergraduates as Active Participants in the Discovery of Biodegrading Thermophiles.

ABSTRACTResearch-based courses are a powerful way to engage undergraduates in the scientific process while simultaneously teaching participants relevant laboratory, analysis, and scientific communication skills. In most programs, students conduct a simulated project which effectively improves student conceptions of scientific thinking but does not produce research-quality data. The course described here delivered an authentic research experience by assigning undergraduates an objective from an active grant-funded project. Participants contributed to research aimed at culturing biodegrading thermophiles from hot springs in Yellowstone National Park. Students participated in a backcountry field experience, collecting environmental samples of their choosing and determining appropriate culturing conditions. Following high-temperature incubations, 16S rRNA gene sequencing identified enriched microbial populations, with analytical and microscopy methods tracking degradation and growth. Importantly, several teams successfully cultivated thermophilic plastic-degrading consortia. Student learning was assessed using several methods, including grade distributions on assignments and statistical comparisons of pre- and posttests. A consistent and, in most cases, statistically significant increase was observed in the students’ posttest scores. The grade distribution on summative assessments also suggests that students achieved the desired learning outcomes. Student perceptions of their learning and experience gains were high, with participants reporting improvements in components emphasized in the research activities. Overall, the findings highlight how involving undergraduates in real-world research projects can enhance student interest and ownership of scientific research, along with contributing quality data that inform active studies.

Best practices for taking experiential learning online

Like many institutions around the world, the COVID-19 pandemic prompted us to shift our summer 2020 in-person undergraduate experiential learning program to a remote, virtual format. Here, we present our observations, summarized in 10 best practices, for moving a STEM-focused research experience for undergraduates, experiential learning program, or research-based course online. We will also discuss how our program was originally designed and implemented, and how we adapted our activities to deliver an at-home research experience that maintained student engagement, mentorship, and a shared sense of community.

CREARE: A Course-Based Undergraduate Research Experience To Study the Responses of the Endangered Coral Acropora cervicornis to a Changing Environment.

There is mounting evidence to support that students who participate in scientific research experiences are more likely to continue on to advanced degrees and careers in science, technology, engineering, and mathematics (STEM). To introduce more students to the benefits of research, we have drawn on an ongoing project aimed at understanding how the Caribbean staghorn coral Acropora cervicornis responds to environmental fluctuations to develop a semester-long course-based undergraduate research experience (CURE), entitled CREARE (Coral Response to Environment Authentic Research Experience). The main mode of instruction in CREARE is through topic modules, and course evaluation is achieved through writing assignments. Students in CREARE perform experiments in the laboratory to measure the abundance of photo-protective proteins in coral tissue from samples collected at different depths and at different times of the year and analyze environmental data using the R programming language. CREARE participants have contributed to the progress of the research project by generating novel data and making improvements to experimental protocols. Furthermore, pre- and post-course assessment of content knowledge revealed that students perform significantly better on a written exam after participating in CREARE, while also displaying appreciable shifts in attitudes towards science in student perception surveys. In addition, through qualitative analysis of focus group interviews, we gathered evidence to suggest that mediating variables that predict students’ persistence in science are bolstered through our application of the CURE modality. Overall, CREARE can serve as a model for developing more research-based courses that successfully engage students in scientific research.

Is This Science? Students’ Experiences of Failure Make a Research-Based Course Feel Authentic

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.

Supporting Students from Day 1 of College: The Importance of Relatedness to Inclusivity.

Day 1: Watershed (WS) is a first-year program designed to provide an inclusive environment for students and immerse them in research from day 1 of college. Originally developed to support students from underrepresented groups (URGs) including first-generation students and students of color, WS provides authentic research experiences for all students as they collect and analyze water and microbiological samples from the local watershed. WS also includes a living–learning community with students living in the same dorm and taking common courses during their first year. In the first year of our study, researchers investigated students’ anxieties, feelings of belonging or isolation, supports received, and personal habits. In year 2 (the primary year reported), researchers used mixed-methods and self-determination theory to determine how WS students differed from students in other introductory and research-based courses in terms of basic psychological needs satisfaction (including autonomy, competence, and relatedness). Results indicated that although WS students felt less autonomous and, at times, less competent than other students, 90% reported a positive experience. Furthermore, findings suggest that WS students’ feelings of connection with classmates and instructors, as well as a sense of belonging in the course, provided the necessary motivational support to facilitate a positive learning experience. These findings indicate that the WS program can be a viable model for supporting students in early science courses and making them feel included.

Application of Flipped Classroom in postgraduate molecular biology technology teaching

Techniques in Molecular Biology is an essential course designed for postgraduates majoring in medicine, biology and other related disciplines. We discussed here the significance of redesigning and the practical attempt, which specifically was the flip classroom model of research-based experimental course dominated by postgraduates. In this teaching model, according to the procedure of research work, postgraduates studied the experiment principle, read kit manual and selected controls before class. In the class, students in groups performed experiments and analyzed the experimental results. The teacher led students' technical operation to achieve the teaching targets and emphasized the evaluation for students' abilities of experimental design and results analysis. Online platform was maintained even after the course in order to achieve long-term academic communication. Key words: Flipped Classroom; Molecular biology technology; Autonomous research learning; Web-based instruction

Knowledge and attitudes of undergraduate medical students with regard to medical research at a South African university

Background. The early introduction of medical students to medical research-related courses is one of the innovative solutions devised by medical schools to address the dearth of physician-scientists. Objective. To describe the knowledge and attitudes of medical students towards medical research at a medical school where research and measurement skills are taught from the first year of study. Methods. A validated, pretested self-administered questionnaire was employed in a cross-sectional study to collect data from 228 third- and fourth-year medical students at Sefako Makgatho Health Sciences University (SMU), Pretoria, South Africa in April 2017. Knowledge of medical research was assessed with a 15-item questionnaire, and attitude towards research was measured with a 10-item scale. The data were analysed with Epi Info (Centers for Disease Control and Prevention, USA) and findings are presented as means, percentages, proportions and tables. The χ2 test was used to assess association among the variables, with p <0.05 considered significant. Results. The mean age of the 228 participants was 22.7 (standard deviation 2.55) years, with ages ranging between 19 and 36 years; 66.2% were female. Although only a few (22%) had prior research experience and less than half (36%) were confident to interpret medical research, the mean score on research knowledge was 73% and a positive attitude towards research was demonstrated. Statistical significance was found between having previous research experience and ability to interpret medical research (χ2=12.8; p =0.01), and between age and having previous research experience (χ2=35.7; p =0.01). Conclusion. The findings revealed a good knowledge and positive attitude to medical research among the students. All these outcomes are the result of early exposure to medical research. More research-based courses are recommended for medical students, without overloading the medical curriculum.

Designing a Real-World Course for Environmental Studies Students: Entering a Social-Ecological System

There is increasing interest in using “real-world pedagogy” to train students in ways that make them better able to contribute toward a more sustainable society. While there is a robust body of literature on the competencies that students need as sustainability professionals, there is a lack of specific guidance in the literature on how to teach for competency development or on how to structure a program or course to support competency development. Our research addresses this gap in the literature through a description and autoethnographic reflection on the design and early implementation of a “real-world” course. The course is from the Environmental Studies Program at Dartmouth College (Hanover, NH, USA), but it takes place in the environs of the Gobabeb Research and Training Centre in the Namib Desert of Namibia and in nearby Topnaar settlements. Our research objective was to articulate strategies to address the primary pedagogical challenges that we faced during the design and first five iterations of the course. These include: How do we frame this course and communicate it to students in a way that is understandable and works within the particular context and constraints of the course? Can we provide students with a coherent framework that helps them to understand the approach and also provides a platform for thoughtful consideration, acquisition, and retention of appropriate competencies? How do we develop collaborations with our community partners that are ethical and effective? How do we frame these real-world experiences in a way that allows for students to integrate their experience with the theory and broader empiricism they learn on campus? To address these pedagogic challenges, we framed the course as a research-based course, more specifically community-based research (CBR), conducted in a social-ecological system (SES). We developed lower-level strategies for implementing this framing, including preparing students for collaborative research, encouraging student ownership of their learning, linking theory to research, and thoughtfully navigating time constraints. Furthermore, program-level and student-level engagement with community have been critical for avoiding becoming “helicopter researchers.” Drawing on our personal reflections and those of our community partners, we conclude with a discussion of emergent outcomes and the next steps for continual improvement and adaptation.

Identifying the optimal course delivery platform in an undergraduate animal behavior research course.

There is a critical need to evaluate pedagogical delivery platforms best suited for undergraduates in the information age. Our goal was to identify the optimum course delivery platform for a basic research course based on student performance and critical thinking scores. Students were expected to plan, conduct, and report on an animal behavior research project of their own design. The course was taught in three different formats: traditional, online, and flipped, over 2 yr by the same instructor at both the University of Florida and Santa Fe College. Student assessments included weekly quizzes, assignments, a written report, a poster presentation, and attendance. We conducted pre- and postassessments using the Cornell Critical Thinking Test (CCTT). Students’ grades differed depending on format delivery and were also different between University of Florida and Santa Fe College students. For students at the University of Florida, quiz grades and poster grades did not differ (P < 0.50) between formats. However, assignment grades (P = 0.04) and report grades (P < 0.001) differed by format and were higher in the flipped and online-only version of the course, compared with traditional. For students at the Santa Fe College, quiz grades (P = 0.71) did not differ, but assignment (P < 0.001), report (P = 0.003), and poster (P < 0.001) grades were higher in the flipped and traditional format of the course. Within the flipped format at the University of Florida, student CCTT scores increased (P < 0.001) between pre- and posttest, whereas the scores within the other formats did not differ. When we compared the magnitude of change between pre- and posttest scores across formats, students at the University of Florida in the flipped format tended (P = 0.060) to have a greater gain than students in the online format. For students at Santa Fe College, there was no difference between pre- and posttest CCTT scores for any format, and the magnitude of change in scores did not differ between formats. Overall, our results suggest that teaching format influences student grades and critical thinking scores. Different effects were seen in different student populations; however, positive effects of the flipped format on student grades were seen at both institutions. In conclusion, flipped format courses may improve learning and critical thinking in an early research-based course.

Consideration of learning orientations as an application of achievement goals in evaluating life science majors in introductory physics

When considering performing an Introductory Physics for Life Sciences course transformation for one's own institution, life science majors' achievement goals are a necessary consideration to ensure the pedagogical transformation will be effective. However, achievement goals are rarely an explicit consideration in physics education research topics such as metacognition. We investigate a sample population of 218 students in a first-semester introductory algebra-based physics course, drawn from 14 laboratory sections within six semesters of course sections, to determine the influence of achievement goals on life science majors' attitudes towards physics. Learning orientations that, respectively, pertain to mastery goals and performance goals, in addition to a learning orientation that does not report a performance goal, were recorded from students in the specific context of learning a problem-solving framework during an in-class exercise. Students' learning orientations, defined within the context of students' self-reported statements in the specific context of a problem-solving-related research-based course implementation, are compared to pre-post results on physics problem-solving items in a well-established attitudinal survey instrument, in order to establish the categories' validity. In addition, mastery-related and performance-related orientations appear to extend to overall pre-post attitudinal shifts, but not to force and motion concepts or to overall course grade, within the scope of an introductory physics course. There also appears to be differentiation regarding overall course performance within health science majors, but not within biology majors, in terms of learning orientations; however, health science majors generally appear to fare less well on all measurements in the study than do biology majors, regardless of learning orientations.
