Project description:The Flipped Science Fair (FSF) transforms the traditional science fair format by having middle-school students judge the research of early career scientists. At the FSF, students learn about cutting-edge research in a small group setting, with opportunities to ask questions and participate in hands-on demonstrations. By placing the students in the role of the "judge," the event gives students the opportunity to engage with scientists interactively and with authority. The FSF also provides science communication training for the presenting scientists. Leading up to the event, the presenters attend three workshops focused on distilling their research message to a middle-school level. The FSF effectively promoted science engagement by middle school students who expressed increased interest in science after the event. Moreover, presenters reported an improvement in their science communication skills to a broad audience and increased confidence during public speaking. Our partnership with Pathways to Science, Yale's coordinated STEM outreach infrastructure, enables us to measure the FSF's effectiveness long term, since the Pathways program tracks student trajectories through their college education. The success of the FSF led to the organization of satellite and virtual events, which provided more opportunities for public engagement and gave presenters additional chances to share their research.
Project description:Nearly half of all undergraduates are enrolled at community colleges (CCs), including the majority of U.S. students who represent groups underserved in the sciences. Yet only a small minority of studies published in discipline-based education research journals address CC biology students, faculty, courses, or authors. This marked underrepresentation of CC biology education research (BER) limits the availability of evidence that could be used to increase CC student success in biology programs. To address this issue, a diverse group of stakeholders convened at the Building Capacity for Biology Education Research at Community Colleges meeting to discuss how to increase the prevalence of CC BER and foster participation of CC faculty as BER collaborators and authors. The group identified characteristics of CCs that make them excellent environments for studying biology teaching and learning, including student diversity and institutional cultures that prioritize teaching, learning, and assessment. The group also identified constraints likely to impede BER at CCs: limited time, resources, support, and incentives, as well as misalignment between doing research and CC faculty identities as teachers. The meeting culminated with proposing strategies for faculty, administrators, journal editors, scientific societies, and funding agencies to better support CC BER.
Project description:Approximately 4 μg of DNA was isolated from blood of each of 16 subjects using the Qiagen DNEasy Blood and Tissue Kit. Of the 16 samples, 8 were from group 1 (CESD-H/TST-H; 5 female, 3 male) and 8 were from group 2 (CESD-H/TST-L; 5 female, 3 male). All DNA samples were confirmed to be of high purity (A260/280: 1.7-2.0). Pooled samples were prepared for each group by combining approximately 75 ng of DNA from each of the eight subjects. These two samples were submitted to the Yale Genomics Core for epigenome-wide methylation profiling using the Illumina Infinium HumanMethylation450 BeadChip, which measures the level of methylation β (a value ranging from 0 to 1, where 0 represents a completely unmethylated site and 1 a completely methylated site) at each of the 485,577 CpG sites on the array. Illumina’s GenomeStudio software was used to calculate the degree of differential methylation by group for each CpG site on the array, and FDR-adjusted p-values (Q-values) were calculated for each site in order to adjust for multiple comparisons.

Project description:Setting students on a path to success in careers in science is a challenge in poor rural Appalachian public schools. Students face many socioeconomic obstacles. Their teachers are also limited by many factors including inadequate facilities, under-funding, geographical isolation of the schools, and state-testing constraints. Additionally, students and teachers lack the availability of outside science educational opportunities. In an effort to address this situation, 24 academically strong high school junior girls and their teachers from the Carter County School System in rural east Tennessee were invited for a laboratory day at Milligan College, a small liberal arts college in the heart of the county. Science faculty, female science majors, and admissions staff volunteered in service to the project. The event included three laboratory sessions, lunch in the college cafeteria, and campus tours. This successful example, as evidenced by positive evaluations by the invited girls and their teachers, of educational outreach by a local, small liberal arts college to a rural county school system provides a model for establishing a relationship between higher education institutions and these underprivileged schools, with the intention of drawing more of these poor, rural Appalachian students, particularly girls, into a science, technology, engineering, and mathematics (STEM) career path.

Project description:A one-credit hour, elective, professional development course was created at North Carolina State University to introduce pre-veterinary track students to the admissions process and the breadth of the veterinary profession. The course was designed to facilitate career exploration while building self-efficacy through vicarious learning, interacting with speakers in various veterinary subfields, and addressing misperceptions about veterinary admissions. To evaluate the student learning objectives and improve upon the current practices of the course, data from two pretest and posttest course surveys for 235 course participants between Spring 2014 and 2017 were analyzed. The results of the study showed that students experienced significant gains in self-appraisal (Cohen's d ranged 1.88 to 2.53), gathering occupational information (Cohen's d ranged 1.59 to 2.53), goal selection (Cohen's d ranged 2.14 to 2.53), and planning and problem-solving (Cohen's d ranged 1.88 to 2.77) as well as experienced a decrease in five misperceptions about veterinary admissions. This novel course is presented as a prospective course for other universities.
Project description:Identifying as a "science person" is predictive of science success, but the mechanisms involved are not well-understood. We hypothesized that science identity predicts success because it fosters a sense of belonging in science classrooms. Thus, science identity should be particularly important for first-generation and racial-minority students, who may harbor doubts about belonging in science. Two field studies in college Introductory Biology classes (Ns = 368, 639) supported these hypotheses. A strong science identity predicted higher grades, particularly for minority students. Also consistent with hypotheses, Study 2 found that self-reported belonging in college mediated the relationship between science identity and performance. Furthermore, a social belonging manipulation eliminated the relationship between science identity and performance among minority students. These results support the idea that a strong science identity is particularly beneficial for minority students because it bolsters belonging in science courses. Practical and theoretical implications are discussed.
