    The goal of this study was to explore and understand the factors that influence students' intention to major in and complete an undergraduate program in a science, technology, engineering, or mathematics (STEM) discipline, in a non-STEM field, and how students' gender directly and indirectly affects their success in college. A quantitative study of three thousand four (3004) ACT-tested students who entered a Midwestern, land-grant university as freshmen in fall, 1999 was conducted based on their ACT Assessment information and their enrollment and graduation status after five years. A wide variety of variables were considered and logistic regression, factor analysis, and path analysis were used to analyze the data. The results show that students who intended to major in or completed STEM programs generally have better academic qualifications than their counterparts who intended to major in non-STEM fields. Students who intended to major in or completed STEM programs came from lower income families and smaller communities than those who intended to major in or graduated from non-STEM programs. In this study, gender's direct effect on students' college achievement is eleven times the total of gender's indirect effects through several major factors for students in both STEM fields and non-STEM fields. Perhaps nature has favored females when students' achievement is measured as their college GPA. The results also show that the overall high dropout rate is strongly associated with students' inadequate preparation in high school and family income. Out-of-school accomplishment in community service is a negative influence on their completion of a college degree. ACT scores are not necessary for prediction of college graduation.

    Wuhib, Frehiwot Wondimu

    This study is an exploratory case study which explored the residential environment of an Ethiopian public university on its role for the social and academic integration of undergraduate women in Science, Technology, Engineering, and Mathematics (STEM) fields. It also explained how the social and academic integration of the women contributed for their overall college success. There were three groups of participants; undergraduate women in STEM, female resident proctors, and relevant officials from the university and the Ministry of Education of the Ethiopian government. Each of the participants were interviewed on a one-on-one basis and the interviews were transcribed and coded for the analysis. Supportive quantitative data about the enrollment, performance and retention of students were also gathered from the university's registrar office and analyzed quantitatively to support the qualitative data obtained through interviews. The study was framed by Tinto's Integration Model and data were interpreted using Third World feminist theory. The findings showed that due to the fact that all same-sex, same-major women living in the same rooms, and all who live in one dorm take similar courses throughout their program, and dormitories serving multiple roles, including being collaboration spaces, played a big role for better social and academic integration of the women. It is also found that their social and academic integration helped them to better perform in their majors by enhancing their sense of belonging in the male-dominated STEM majors, enhancing their commitment, and promoting peer encouragement. On the other hand, the findings also showed that there were some factors which have negative influence in the integration process such as negative stereotypes against the presence and good performance of women in STEM, lack of support system, and limited interaction with faculty. So, the study recommends that working on improving the negatively influencing factors will

    Elementary teachers often hold inaccurate beliefs about the Nature of Science (NoS) and have negative attitudes toward science and mathematics. Using a pre-post design, the current study examined beliefs about the NoS, attitudes toward science and mathematics, and beliefs about the teaching of mathematics and science in a large sample study (N = 343) of pre-service teachers receiving a curriculum-wide intervention to improve these factors in comparison with Science, Technology, Engineering, and Mathematics (STEM) and non-STEM majors in other physics courses (N = 6697) who did not receive the intervention, over a 10-year period. Pre-service teachers evidenced initially more negative attitudes about mathematics and science than STEM majors and slightly more positive attitudes than non-STEM majors. Their attitudes toward mathematics and science and beliefs about the NoS were more similar to non-STEM than STEM majors. Pre-service teachers initially evidenced more positive beliefs about the teaching of mathematics and science, and their beliefs even increased slightly over the course of the semester, while these beliefs in other groups remained the same. Beliefs about the NoS and the teaching of mathematics and science were significantly negatively correlated for STEM and non-STEM majors, but were not significantly correlated for pre-service teachers. Beliefs about the NoS and attitudes toward mathematics and science were significantly positively correlated for both pre-service teachers and STEM students pursing the most mathematically demanding STEM majors. Attitudes toward science and mathematics were significantly positively correlated with accurate beliefs about the teaching of mathematics and science for all student groups.

    Pedone, Maggie Helene

    The underrepresentation of women in science, technology, engineering, and mathematics (STEM) is a complex problem that continues to persist at the postsecondary level, particularly in computer science and engineering fields. This dissertation explored the pre-college and college level factors that influenced undergraduate women's persistence in STEM. This study also examined and compared the characteristics of undergraduate women who entered STEM fields and non-STEM fields in 2003-2004. The nationally representative Beginning Postsecondary Students Longitudinal Study (BPS:04/09) data set was used for analysis. BPS:04/09 study respondents were surveyed three times (NPSAS:04, BPS:04/06, BPS:04/09) over a six-year period, which enabled me to explore factors related to long-term persistence. Astin's Input-Environment-Output (I-E-O) model was used as the framework to examine student inputs and college environmental factors that predict female student persistence (output) in STEM. Chi-square tests revealed significant differences between undergraduate women who entered STEM and non-STEM fields in 2003-2004. Differences in student demographics, prior academic achievement, high school course-taking patterns, and student involvement in college such as participation in study groups and school clubs were found. Notably, inferential statistics showed that a significantly higher proportion of female minority students entered STEM fields than non-STEM fields. These findings challenge the myth that underrepresented female minorities are less inclined to enter STEM fields. Logistic regression analyses revealed thirteen significant predictors of persistence for undergraduate women in STEM. Findings showed that undergraduate women who were younger, more academically prepared, and academically and socially involved in college (e.g., lived on campus, interacted with faculty, participated in study groups, fine arts activities, and school sports) were more likely to persist in STEM

  10. Women in STEM: The Effect of Undergraduate Research on Persistence

    Science.gov (United States)

    Wilker, Jodi

    The underrepresentation of women in science, technology, engineering, and math (STEM) careers constitutes a major issue in postsecondary science education. Perseverance of women in STEM is linked to a strong science identity. Experiential learning activities, such as undergraduate research, increase science identity and thus should help keep women in STEM. Most studies on research program development are from 4-year institutions, yet many women start at community colleges. The goal of this study was to fill this gap. Science identity and experiential learning theories provided the framework for this case study at a local institution (LECC). Semistructured interviews determined college science faculty and administrators perceptions of advantages and disadvantages of undergraduate research, the viability of developing a research program, and specific research options feasible for LECC. Transcripted data were analyzed through multiple rounds of coding yielding five themes: faculty perception of undergraduate research, authentic experiences, health technologies/nursing programs, LECC students career focus, and the unique culture at LECC. The most viable type of undergraduate research for LECC is course-based and of short timeframe. The project study advocates the use of citizen science (CS) studies in the classroom as they are relatively short-term and can take the place of lab sessions. The true benefit is that students perform authentic science by contributing to an actual scientific research project. CS projects can effect social change by developing science literate citizens, empowering faculty to create authentic learning experiences, and by sparking interest in science and directing women into STEM careers.

  12. How Undergraduate Women Choose STEM Careers

    Science.gov (United States)

    Hughes, Roxanne

    2013-03-01

    In 2010 women represented half of the US population and over half of current graduates from college (57%) but less than a third of undergraduate degrees in science and engineering (STEM). This underrepresentation is worse in certain fields such as physics (21%), and engineering (22%) compared to 52% in chemistry. This underrepresentation is not only a social and cultural issue, but it is also cause for alarm in regard to the United States' ability to maintain its technological and economic dominance in the global economy. STEM fields provide valuable contributions to the nation's economic and environmental security (Augustine, 2005; Chang, 2009; Riegle-Crumb and King, 2010; Robelen, 2010; Tessler, 2008), paying practitioners well and bringing in revenue for successful businesses and governments (National Science Board [NSB], 2008; Riegle-Crumb and King). Consequently, addressing the underrepresentation of women and increasing their persistence in STEM fields will increase the number of scientists and engineers contributing to these fields, which could, in turn, improve the nation's economy, safety, and technological revenues. Research indicates that there are internal and external factors that affect the ability of women to see future success in STEM and to identify with the STEM and consequently persist. This presentation will summarize the current literature on issues affecting undergraduate women's retention in STEM as well as present strategies to improve this retention. Part of this presentation will draw from my own research studies in this area. The findings from my study and others reveal that only women who participate in redefinition strategies related to their marginalized status are able to persist; those who cannot redefine their marginality in relation to the dominant discourse of STEM begin to lose interest or doubt their competence in the field, resulting in their departure from STEM.

    The NSF-sponsored Undergraduate ALFALFA (Arecibo Legacy Fast ALFA) Team (UAT) is a consortium of 19 institutions founded to promote undergraduate research and faculty development within the extragalactic ALFALFA HI blind survey project and follow-up programs. The collaborative nature of the UAT allows faculty and students from a wide ​range of public and private colleges and especially those with small astronomy programs to develop scholarly collaborations. Components of the program include an annual undergraduate workshop at Arecibo Observatory, observing runs at Arecibo, computer infrastructure, summer and academic year research projects, and dissemination at national meetings (e.g., Alfvin et al., Martens et al., Sanders et al., this meeting). Through this model, faculty and students are learning how science is accomplished in a large collaboration while contributing to the scientific goals of a major legacy survey. In the 7 years of the program, 23 faculty and more than 220 undergraduate students have participated at a significant level. 40% of them have been women and members of underrepresented groups. Faculty, many of whom were new to the collaboration and had expertise in other fields, contribute their diverse sets of skills to ALFALFA ​related projects via observing, data reduction, collaborative research, and research with students. 142 undergraduate students have attended the annual workshops at Arecibo Observatory, interacting with faculty, graduate students, their peers, and Arecibo staff in lectures, group activities, tours, and observing runs. Team faculty have supervised 131 summer research projects and 94 academic year (e.g., senior thesis) projects. 62 students have traveled to Arecibo Observatory for observing runs and 46 have presented their results at national meetings. 93% of alumni are attending graduate school and/or pursuing a career in STEM. Half of those pursuing graduate degrees in Physics or Astronomy are women. This work has been

  15. Reforming STEM Undergraduate Education: What's a Faculty Member to Do?

    Fairweather, J.

    2011-12-01

    Efforts to improve undergraduate STEM education lie at the forefront of many national educational policies. The recent National Academies of Science study of discipline-based educational research (DBER)is typical of such efforts. Most of the initiatives to improve student learning in STEM focus on the the student or the instructor in the classroom (Austin, 2011). This focus is consistent with the work by Seymour & Hewitt (1997), which found that poor teaching in STEM adversely affects learning and retention in the major. Professional development efforts focus on helping the individual STEM faculty member to figure out what to do to improve student learning. Substantial research (Austin, 2011) shows that the origin of many learning problems lies beyond the control of the instructor or the individual classroom. In these circumstances what is a STEM faculty member to do? This paper explores answers to this question. The first step is to define the nature of the problem. Is it related to classroom teaching and learning such as knowledge, skills, and interest in the major? If so then what environmental factors affect strategic alternatives, including type of course, instructor characteristics, and prior teaching experience (Fairweather & Rhoads, 1995)? Does good disciplinary-based research on the learning problem exist? If so then how can the research results be translated into practice? If not then does good research from other disciplines exist? If relevant evidenced-based research does not exist at all then how can STEM instructors learn to evaluate key learning outcomes and find ways to ameliorate problems? Despite appearances not all STEM teaching and learning problems are classroom-based. Some problems derive from curricula, others from faculty work-related issues such as rewards and work load. Any classroom reform effort must reflect accurately the system in which the teaching and learning take place. Understanding these systemic interactions improves the ability

    In the United States, less than half of the students who enter into science, technology, engineering, and mathematics (STEM) undergraduate curricula as freshmen will actually graduate with a STEM degree. There is even greater disparity in the national STEM graduation rates of students from underrepresented groups with approximately three-fourths of minority students leaving STEM disciplines at the undergraduate level. A host of programs have been designed and implemented to model best practices in retaining students in STEM disciplines. The Howard Hughes Medical Institute (HHMI) Professors Program at Louisiana State University, under leadership of HHMI Professor Isiah M. Warner, represents one of these programs and reports on a mentoring model that addresses the key factors that impact STEM student attrition at the undergraduate level. By integrating mentoring and strategic academic interventions into a structured research program, an innovative model has been developed to guide STEM undergraduate majors in adopting the metacognitive strategies that allow them to excel in their programs of study, as they learn to appreciate and understand science more completely. Comparisons of the persistence of participants and nonparticipants in STEM curricular, at the host university and with other national universities and colleges, show the impact of the model's salient features on improving STEM retention through graduation for all students, particularly those from underrepresented groups.

  18. Berkeley's Advanced Labs for Undergraduate Astronomy Majors

    Heiles, C.

    1998-12-01

    We currently offer three advanced laboratory courses for undergraduate majors: optical, IR, and radio. These courses contain both intellectual and practical content; in this talk we focus on the radio lab as a representative example. The first half of the semester concentrates on fundamentals of microwave electronics and radio astronomy techniques in four formal laboratory exercises which emphasize hands-on use of microwave devices, laboratory instruments, and computer-controlled data taking. The second half of the course emphasizes astronomy, using a horn with ~ 1 m(2) aperture to map the HI in the Galaxy and a two-element interferometer composed of ~ 1 m diameter dishes on a ~ 10 m baseline to measure accurate positions of radio sources and accurate diameters for the Sun and Moon. These experiments and observations offer ideal opportunities for teaching coordinates, time, rotation matrices, data reduction techniques, least squares, signal processing, image processing, Fourier transforms, and laboratory and astronomical instrumentation. The students can't get along without using computers as actually used by astronomers. We stay away from packaged software such as IRAF, which are ``black boxes''; rather, students learn far more by writing their own software, usually for the first time. They use the IDL language to take and reduce data and prepare them for the lab reports. We insist on quality reports---including tables, postscript graphs and images, correct grammar, spelling, and all the rest---and we strongly urge (successfully!) the students to use LATEX. The other two lab courses have the same emphasis: the guiding spirit is to place the students in a real-life research-like situation. There is too much to do, so students perform the work in small groups of 3 or 4 and groups are encouraged to share their knowledge. Lab reports are written individually. These courses are very demanding, requiring an average of 20 hours per week from the students (and probably

    2017-01-01

    Recent calls to action urge sweeping reform in science education, advocating for improved learning for all students—including those majoring in fields beyond the sciences. However, little work has been done to characterize the differences—if any exist—between students planning a career in science and those studying other disciplines. We describe an attempt to clarify, in broad terms, how non–STEM (science, technology, engineering, and mathematics) majors differ from life sciences majors, and how they are similar. Using survey responses and institutional data, we find that non–STEM majors are not unilaterally science averse; non–STEM majors are more likely than biology majors to hold misconceptions about the nature of science, yet they are not completely ignorant of how science works; non–STEM majors are less likely than biology majors to see science as personally relevant; and non–STEM majors populations are likely to be more diverse—with respect to incoming knowledge, perceptions, backgrounds, and skills—than a biology majors population. We encourage science educators to consider these characteristics when designing curricula for future scientists or simply for a well-informed citizenry. PMID:28798210

  20. Patching the Leaky STEM Pipeline: Identifying Institutional Factors That Influence a STEM Qualified Female Undergraduate s Choice of Institution

    Science.gov (United States)

    Hurlock, Ashley J.

    Despite increased female participation in the workforce and females earning more undergraduate degrees than men over the past decade, women are still awarded fewer undergraduate degrees than men and hold less than 25% of jobs in the areas of science, technology, engineering and math, or STEM (Beede, et al., 2011). Research shows that females may be leaking from the STEM pipeline because they are not choosing to attend institutions that fulfill their interdisciplinary and non-academic interests or have learning environments that are supportive of their needs. The purpose of this quantitative, cross-sectional survey study, conducted at one non-research intensive university, was to identify institutional factors most pertinent to the decision to attend a non-research intensive university by a "STEM qualified" female undergraduate student. 23 of 45 factors were reported as positively influencing their decision regardless of major. The top six factors for both groups were: average class size, campus environment, a visit to campus, university population size, and major/department offered. The seven factors ranked statistically significantly different between STEM and non-STEM majors were undergraduate research opportunities, faculty reputation, graduate/professional school admission, academic support/tutoring, graduate program available, intramural sports, and off-campus housing. Only two of 17 factors negatively influenced STEM majors who were accepted to a research intensive university: the research intensive university's size and average class sizes were undesirable compared to their current institution. STEM qualified females weighed the importance of non-academic factors as high, or higher, than critical academic factors. STEM qualified females are also choosing to attend the non-research intensive university for a variety of reasons and not simply because another institution did not offer certain academic factors. Future studies should expanded to include other non

  1. A Study of The Influence of Advising on Underrepresented Minority Undergraduate Student Persistence in STEM

    Science.gov (United States)

    Weir, Michael J.

    In the United States, undergraduate underrepresented minority (URM) students tend to change out of declared majors in science, technology, engineering and math (STEM) disciplines at a rate of nearly sixty percent prior to earning a post secondary degree. This phenomenon contributes to a general concern that the United States is not producing enough STEM trained skilled workers to meet future employment needs of industry and government. Although there has been research developed to examine how to increase the numbers of URM students enrolling in STEM programs at higher education institutions, retention of these students remains critical. One area of increasing focus for researchers is to understand how multiple factors impact the college experience of URM students and how those factors may contribute to the student decision to persist in earning a STEM disciple degree. This research study is a phenomenological mixed method study that examines how students experience the phenomenon of advising and the influence of the advising experience of undergraduate URM students on their likelihood of persisting in STEM at a northeast US technology oriented post secondary institution. Persistence, from the perspective of the student, is driven by cognitive psychological attributes such as confidence, motivation and self-efficacy. Utilizing a Social Cognitive theoretical framework, this study examines how three distinct undergraduate URM student populations enrolled in; an Academic Services Program, Honors College, and the general undergraduate population at this institution experience advising and how their experiences may influence their propensity to persist in earning a STEM oriented degree.

    The APA Guidelines for the Undergraduate Psychology Major: Version 2.0 (henceforth Guidelines 2.0; APA, 2013) represents a national effort to describe and develop high-quality undergraduate programs in psychology. The task force charged with the revision of the original guidelines for the undergraduate major examined the success of the document's implementation and made changes to reflect emerging best practices and to integrate psychology's work with benchmarking scholarship in higher education. Guidelines 2.0 abandoned the original distinction drawn between psychology-focused skills and psychology skills that enhance liberal arts development. Instead, Guidelines 2.0 describes five inclusive goals for the undergraduate psychology major and two developmental levels of student learning outcomes. Suggestions for assessment planning are provided for each of the five learning goals. (c) 2016 APA, all rights reserved).

  5. Sex segregation in undergraduate engineering majors

    Science.gov (United States)

    Litzler, Elizabeth

    Gender inequality in engineering persists in spite of women reaching parity in college enrollments and degrees granted. To date, no analyses of educational sex segregation have comprehensively examined segregation within one discipline. To move beyond traditional methods of studying the long-standing stratification by field of study in higher education, I explore gender stratification within one field: engineering. This dissertation investigates why some engineering disciplines have a greater representation of women than other engineering disciplines. I assess the individual and institutional factors and conditions associated with women's representation in certain engineering departments and compare the mechanisms affecting women's and men's choice of majors. I use national data from the Engineering Workforce Commission, survey data from 21 schools in the Project to Assess Climate in Engineering study, and Carnegie Foundation classification information to study sex segregation in engineering majors from multiple perspectives: the individual, major, institution, and country. I utilize correlations, t-tests, cross-tabulations, log-linear modeling, multilevel logistic regression and weighted least squares regression to test the relative utility of alternative explanations for women's disproportionate representation across engineering majors. As a whole, the analyses illustrate the importance of context and environment for women's representation in engineering majors. Hypotheses regarding hostile climate and discrimination find wide support across different analyses, suggesting that women's under-representation in certain engineering majors is not a question of choice or ability. However, individual level factors such as having engineering coursework prior to college show an especially strong association with student choice of major. Overall, the analyses indicate that institutions matter, albeit less for women, and women's under-representation in engineering is not

This study examines an undergraduate teaching assistant (UTA) program implemented in a general chemistry course for STEM majors to provide peer learning assistance to entrylevel students. This study measured the content knowledge growth of UTAs compared to traditional graduate teaching assistants (GTAs) over the semester, and described the development of peer learning assistance skills of the UTAs as an outcome of semesterlong training and support from both science education and STEM faculty. Impact of the UTA program on final exam grades, persistence of students to enroll in the next chemistry course required by their intended major, and STEM identity of students were estimated. The study sample comprised 284 students in 14 general chemistry recitation sections led by six UTAs and 310 students in 15 general chemistry recitation sections led by three traditional GTAs for comparison. Results suggested that both UTAs and GTAs made significant learning gains in general chemistry content knowledge, and there was no significant difference in content knowledge between UTA and GTA groups. Student evaluations, researcher observations, and chemistry faculty comments confirm UTAs were using the learning strategies discussed in the semester-long training program. UTA-led students rated their TAs significantly higher in teaching quality and student care and encouragement, which correlated with stronger STEM recognition by those students. The results of hierarchical linear model (HLM) analysis showed little variance in final exam grades explained by section-level variables; most variance was explained by student-level variables: mathematics ACT score, college GPA, and intention to enroll in the next general chemistry course. Students having higher college GPAs were helped more by having a UTA. Results from logistic

    Elrod, S.

    2011-12-01

    In 1989, Project Kaleidoscope (PKAL) published its first report, What Works: Building Natural Science Communities, on reforming undergraduate STEM (science, technology, engineering and mathematics) education. Since then, PKAL has grown into a national organization comprised of a diverse group of over 6500 STEM educators who are committed to advancing "what works." The PKAL mission is to be a national leader in catalyzing the efforts of people, institutions, organizations and networks to move from analysis to action in significantly improving undergraduate student learning and achievement in STEM (science, technology, engineering and mathematics). Specifically, PKAL's strategic goals are to: 1) Promote the development and wider use of evidence-based teaching, learning and assessment approaches, 2) Build individual and organizational capacity to lead change in STEM education, and 3) Engage the broader community of external stakeholders - professional and disciplinary societies, business and industry groups, accreditation organizations, educational associations, governmental agencies, philanthropic organizations - in achieving our mission. PKAL achieves these goals by serving as the nexus of an interconnected and multidisciplinary web of people, ideas, strategies, evidence and resources focused on systemic change in undergraduate STEM education. PKAL also provides resources on critical issues, such as teaching using pedagogies of engagement, and engages interested faculty, campuses and professional societies in national projects and programs focused on cutting edge issues in STEM education. One of these projects - Mobilizing Disciplinary Societies for a Sustainable Future - is engaging eleven disciplinary societies, including the National Association of Geoscience Teachers, in defining specific resources, faculty development programs and goals focused on promoting undergraduate STEM courses that: 1) provide more knowledge about real-world issues; 2) connect these real

    Conklin, Stephanie

    This paper explores the lived experiences of high school female students who choose to enter into STEM fields, and describes the influencing factors which steered these women towards majors in computer science, engineering and biology. Utilizing phenomenological methodology, this study seeks to understand the essence of women's decisions to enter into STEM fields and further describe how the decision-making process varies for women in high female enrollment fields, like biology, as compared with low enrollment fields like, computer science and engineering. Using Bloom's 3-Stage Theory, this study analyzes how relationships, experiences and barriers influenced women towards, and possibly away, from STEM fields. An analysis of women's experiences highlight that support of family, sustained experience in a STEM program during high school as well as the presence of an influential teacher were all salient factors in steering women towards STEM fields. Participants explained that influential teacher worked individually with them, modified and extended assignments and also steered participants towards coursework and experiences. This study also identifies factors, like guidance counselors as well as personal challenges, which inhibited participant's path to STEM fields. Further, through analyzing all six participants' experiences, it is clear that a linear model, like Bloom's 3-Stage Model, with limited ability to include potential barriers inhibited the ability to capture the essence of each participant's decision-making process. Therefore, a revised model with no linear progression which allows for emerging factors, like personal challenges, has been proposed; this model focuses on how interest in STEM fields begins to develop and is honed and then mastered. This study also sought to identify key differences in the paths of female students pursuing different majors. The findings of this study suggest that the path to computer science and engineering is limited. Computer

    Adornato, Philip

    The following dissertation focuses on a case study that uses critical theory, social learning theory, identity theory, liberal feminine theory, and motivation theory to conduct a narrative describing the lived experience of females and their performance in two highly selective private university, where students can cross-register between school, while majoring in science, technology, engineering and mathematics (STEM). Through the use of narratives, the research attempts to shed additional light on the informal and formal science learning experiences that motivates young females to major in STEM in order to help increase the number of women entering STEM careers and retaining women in STEM majors. In the addition to the narratives, surveys were performed to encompass a larger audience while looking for themes and phenomena which explore what captivates and motivates young females' interests in science and continues to nurture and facilitate their growth throughout high school and college, and propel them into a major in STEM in college. The purpose of this study was to uncover the lived experiences of junior and senior undergraduate female science majors during their formal and informal education, their science motivation to learn science, their science identities, and any experiences in gender inequity they may have encountered. The findings have implications for young women deciding on future careers and majors through early exposure and guidance, understanding and recognizing what gender discrimination, and the positive effects of mentorships.

  15. Undergraduate Neuroscience Majors: A Missed Opportunity for Psychiatry Workforce Development.

    Science.gov (United States)

    Goldenberg, Matthew N; Krystal, John H

    2017-04-01

    This study sought to determine whether and to what extent medical students with an undergraduate college major in neuroscience, relative to other college majors, pursue psychiatry relative to other brain-based specialties (neurology and neurosurgery) and internal medicine. The authors analyzed data from AAMC matriculation and graduation surveys for all students who graduated from US medical schools in 2013 and 2014 (n = 29,714). Students who majored in neuroscience, psychology, and biology were compared to all other students in terms of their specialty choice at both time points. For each major, the authors determined rates of specialty choice of psychiatry, neurology, neurosurgery, and, for comparison, internal medicine. This study employed Chi-square statistic to compare odds of various specialty choices among different majors. Among medical students with an undergraduate neuroscience major (3.5% of all medical students), only 2.3% preferred psychiatry at matriculation, compared to 21.5% who chose neurology, 13.1% neurosurgery, and 11% internal medicine. By graduation, psychiatry specialty choice increased to 5.1% among neuroscience majors while choice of neurology and neurosurgery declined. Psychology majors (OR = 3.16, 95% CI 2.60-4.47) but not neuroscience majors (OR 1.28, 0.92-1.77) were more likely than their peers to choose psychiatry. Psychiatry struggles to attract neuroscience majors to the specialty. This missed opportunity is an obstacle to developing the neuroscience literacy of the workforce and jeopardizes the neuroscientific future of our field. Several potential strategies to address the recruitment challenges exist.

    Parker, Ashley Dawn

    This research seeks to understand the experiences of African American female undergraduates in STEM. It investigates how familial factors and science identity formation characteristics influence persistence in STEM while considering the duality of African American women's status in society. This phenomenological study was designed using critical race feminism as the theoretical framework to answer the following questions: 1) What role does family play in the experiences of African American women undergraduate STEM majors who attended two universities in the UNC system? 2) What factors impact the formation of science identity for African American women undergraduate STEM majors who attended two universities in the UNC system? Purposive sampling was used to select the participants for this study. The researcher conducted in-depth interviews with 10 African American female undergraduate STEM major from a predominantly White and a historically Black institution with the state of North Carolina public university system. Findings suggest that African American families and science identity formation influence the STEM experiences of the African American females interviewed in this study. The following five themes emerged from the findings: (1) independence, (2) support, (3) pressure to succeed, (4) adaptations, and (5) race and gender. This study contributes to the literature on African American female students in STEM higher education. The findings of this study produced knowledge regarding policies and practices that can lead to greater academic success and persistence of African American females in higher education in general, and STEM majors in particular. Colleges and universities may benefit from the findings of this study in a way that allows them to develop and sustain programs and policies that attend to the particular concerns and needs of African American women on their campuses. Finally, this research informs both current and future African American female

  17. The C-MORE Scholars Program: Engaging minority students in STEM through undergraduate research

    Science.gov (United States)

    Gibson, B. A.; Bruno, B. C.

    2010-12-01

    There have been several studies that show how undergraduate research experiences (REU) have a positive impact on a student’s academic studies and career path, including being a positive influence toward improving the student's lab skills and ability to work independently. Moreover, minority students appear to relate to science, technology, engineering, and mathematics (STEM) concepts better when they are linked with (1) a service learning component, and (2) STEM courses that include a cultural and social aspect that engages the student in a way that does not distract from the student’s technical learning. It is also known that a “place-based” approach that incorporates traditional (indigenous) knowledge can help engage underrepresented minority groups in STEM disciplines and increase science literacy. Based on the methods and best practices used by other minority serving programs and described in the literature, the Center for Microbial Oceanography: Research and Education (C-MORE) has successfully developed an academic-year REU to engage and train the next generation of scientists. The C-MORE Scholars Program provides undergraduate students majoring in an ocean or earth science-related field, especially underrepresented students such as Native Hawaiians and Pacific Islanders, the opportunity to participate in unique and cutting edge hands-on research experiences. The program appoints awardees at one of three levels based on previous research and academic experience, and students can progress through the various tiers as their skills and STEM content knowledge develop. All awardees receive guidance on a research project from a mentor who is a scientist at the university and/or industry. A key component of the program is the inclusion of professional development activities to help the student continue towards post graduation education or prepare for career opportunities after they receive their undergraduate STEM degree.

    2017-01-01

    The persistence of undergraduate students in science, technology, engineering, and mathematics (STEM) disciplines is a national issue based on STEM workforce projections. We implemented a weeklong pre-college engagement STEM Academy (SA) program aimed at addressing several areas related to STEM retention. We validated an instrument that was developed based on existing, validated measures and examined several psychosocial constructs related to STEM (science identity, self-efficacy, sense of belonging to the university and to STEM, career expectancies, and intention to leave STEM majors) before and after the program. We also compared students in the SA program with a matched comparison group of first-year students. Results show that SA students significantly increased in science identity and sense of belonging to STEM and to the university, all predictive of increased STEM retention and a primary aim of the program. Relative to the matched comparison group, SA students began their first semester with higher STEM self-efficacy, sense of belonging, and science identity, positive career expectancies, and lower intention to leave STEM. The SA cohort showed 98% first-year retention and 92% STEM major retention. The SA program serves as a model of a scalable, first-level, cocurricular engagement experience to enhance psychosocial factors that impact undergraduate persistence in STEM. © 2017 D.

    Ray, Tiffany Monique

    The purpose of this study was to investigate the significant factors influencing STEM major selection by African American females. A quantitative research design with a qualitative component was employed. Ex post facto survey research was conducted utilizing an online questionnaire to collect data from participants. African American undergraduate females that had declared a major in STEM comprised the target population for the study. As a basis for comparison, a second data collection ensued. All non-African American undergraduate females majoring in STEM also received the survey instrument to determine if there was a significant difference between factors that influence STEM major selection between the two groups. The Social Cognitive Career Choice Model comprised the conceptual framework for this study. Frequencies and percentages illustrated the demographic characteristics of the sample, as well as the average influence levels of each of the items without regard for level of significance. The researcher conducted an independent samples t-test to compare the mean scores for undergraduate African American females majoring in STEM and non-African American females majoring in STEM on each influential factor on the survey instrument. The researcher coded responses to open-ended questions to generate themes and descriptions. The data showed that African American female respondents were very influenced by the following items: specific interest in the subject, type of work, availability of career opportunities after graduation, parent/guardian, precollege coursework in science, and introductory college courses. In addition, the majority of respondents were very influenced by each of the confidence factors. African American females were overwhelmingly not influenced by aptitude tests. African American females were more influenced than their non-African American female counterparts for the following factors: reputation of the university, college or department, high level

    Ezella McPherson

    2014-11-01

    Full Text Available This research investigates how eight undergraduate African American women in science, math, and engineering (SME majors accessed cultural capital and informal science learning opportunities from preschool to college. It uses the multiple case study methodological approach and cultural capital as the framework to better understand their opportunities to engage in free-choice science learning. The article demonstrates that African American women have access to cultural capital and informal science learning inside and outside of home and school environments in P-16 settings. In primary and secondary schools, African American girls acquire cultural capital and access to free-choice science learning in the home environment, museums, science fairs, student organizations and clubs. However, in high school African American female teenagers have fewer informal science learning opportunities like those such as those provided in primary school settings. In college, cultural capital is transmitted through informal science learning that consisted of involvement in student organizations, research projects, seminars, and conferences. These experiences contributed to their engagement and persistence in SME fields in K-16 settings. This research adds to cultural capital and informal science learning research by allowing scholars to better understand how African American women have opportunities to learn about the hidden curriculum of science through informal science settings throughout the educational pipeline.

  5. Persistence among Minority STEM Majors: A Phenomenological Study

    Science.gov (United States)

    Williams-Watson, Stacey

    The United States needs to increase the number of science, technology, engineering, and math (STEM) graduates to remain competitive in the global market and maintain national security. Minority students, specifically African-American and Hispanic, are underrepresented in STEM fields. As the minority population continues to grow it is essential that higher education institutions improve minority students' persistence in STEM education. This study examined the problem of minority students' lack of persistence in STEM programs. The purpose of this qualitative transcendental phenomenological study was to describe the lived experiences that minority students perceived as contributing to their persistence in STEM. The central research question was: What are the lived experiences of minority STEM students that have contributed to their persistence in a STEM program? The sub-questions were: a) What led participants to majors in STEM?; b) What contributed to students' success and persistence in STEM?; and c) What advice do students have to offer? The researcher interviewed 12 minority STEM students and uncovered 10 themes that described the lived experiences of minority students' persistence in STEM programs. The themes were 1) Childhood experiences and interests; 2) Positive educational experiences in secondary school; 3) Self- motivation; 4) Positive experiences with professors; 5) Family encouragement and values; 6) Lack of minorities; 7) Lack of educational preparation; 8) The need for financial assistance; 9) Clubs and organizations; and 10) Friends within the major. The significance of these findings is the potential to produce changes in curricula, programs, and retention methods that may improve the persistence of minority students in STEM programs.

    2012-04-01

    The relationships of students' preadmission academic variables, sex, undergraduate major, and undergraduate institution to academic performance in medical school have not been thoroughly examined. To determine the ability of students' preadmission academic variables to predict osteopathic medical school performance and whether students' sex, undergraduate major, or undergraduate institution influence osteopathic medical school performance. The study followed students who graduated from New York College of Osteopathic Medicine of New York Institute of Technology in Old Westbury between 2003 and 2006. Student preadmission data were Medical College Admission Test (MCAT) scores, undergraduate grade point averages (GPAs), sex, undergraduate major, and undergraduate institutional selectivity. Medical school performance variables were GPAs, clinical performance (ie, clinical subject examinations and clerkship evaluations), and scores on the Comprehensive Osteopathic Medical Licensing Examination-USA (COMLEX-USA) Level 1 and Level 2-Clinical Evaluation (CE). Data were analyzed with Pearson product moment correlation coefficients and multivariate linear regression analyses. Differences between student groups were compared with the independent-samples, 2-tailed t test. A total of 737 students were included. All preadmission academic variables, except nonscience undergraduate GPA, were statistically significant predictors of performance on COMLEX-USA Level 1, and all preadmission academic variables were statistically significant predictors of performance on COMLEX-USA Level 2-CE. The MCAT score for biological sciences had the highest correlation among all variables with COMLEX-USA Level 1 performance (Pearson r=0.304; Posteopathic medical school performance, including GPAs, clinical performance, and COMLEX-USA Level 1 and Level 2-CE results. Clinical performance was predictive of COMLEX-USA Level 2-CE performance.

    The 6-yr degree-completion rate of undergraduate science, technology, engineering, and mathematics (STEM) majors at U.S. colleges and universities is less than 40%. Persistence among women and underrepresented minorities (URMs), including African-American, Latino/a, Native American, and Pacific Islander students, is even more troubling, as these students leave STEM majors at significantly higher rates than their non-URM peers. This study utilizes a matched comparison group design to examine the academic achievement and persistence of students enrolled in the Program for Excellence in Education and Research in the Sciences (PEERS), an academic support program at the University of California, Los Angeles, for first- and second-year science majors from underrepresented backgrounds. Results indicate that PEERS students, on average, earned higher grades in most "gatekeeper" chemistry and math courses, had a higher cumulative grade point average, completed more science courses, and persisted in a science major at significantly higher rates than the comparison group. With its holistic approach focused on academics, counseling, creating a supportive community, and exposure to research, the PEERS program serves as an excellent model for universities interested in and committed to improving persistence of underrepresented science majors and closing the achievement gap. © 2015 B.

  13. Female STEM majors wanted: The impact of certain factors on choice of a college major

    Science.gov (United States)

    Conrad, Walter Michael

    Although females have made significant strides in educational achievements and substantial inroads into academic majors, such as business and medicine, they have made considerably less progress in the science, technology, engineering, and math (STEM) fields. This translates into a smaller number of female graduates prepared to work in the science career fields and results in American industry looking to other countries for its educated workforce. A mixed-methods research design was used to explore and understand the lived experiences and perceptions of faculty members and working STEM professionals in Northern and Central Virginia. Results indicated that although females are attaining STEM degrees and entering STEM fields in record numbers, obstacles such as a challenging STEM curriculum, bias, feelings of insecurity, lack of female role models, and inadequate preparation for the STEM workforce could impede the progress females have made. This research makes recommendations to the academic community and industry which may be used as retention and recruitment strategies for females considering a career in STEM. The ultimate goal is to significantly increase the number of highly skilled female graduates entering STEM fields, leading the U.S. to regain its previous position atop the world in technological innovation and leadership.

    The University of Arizona Astronomy Club has been working on two large group research projects since 2009. One research project is a transiting extrasolar planet project that is fully student led and run. We observed the transiting exoplanets, TrES-3b and TrES-4b, with the 1.55 meter Kupier Telescope in near-UV and optical filters in order to detect any asymmetries between filters. The second project is a radio astronomy survey utilizing the Arizona Radio Observatory 12m telescope on Kitt Peak to study molecular gas in cold cores identified by the Planck all sky survey. This project provides a unique opportunity for a large group of students to get hands-on experience observing with a world-class radio observatory. These projects involve students in every single step of the process including: proposal writing to obtain telescope time on various Southern Arizona telescopes, observing at these telescopes, data reduction and analysis, managing large data sets, and presenting results at scientific meetings and in journal publications. The primary goal of these projects is to involve students in cutting-edge research early on in their undergraduate studies. The projects are designed to be continuous long term projects so that new students can easily join. As of January 2012 the extrasolar planet project became an official independent study class. New students learn from the more experienced students on the projects creating a learner-centered environment.

    The University of Arizona Astronomy Club has been working on two large group research projects since 2009. One research project is a transiting extrasolar project that is fully student led and run. We observed the transiting extrasolar planets, TrES-3b and TrES-4b, with the 1.55 meter Kuiper Telescope using different filters to test a proposed method of detecting extrasolar planet magnetic fields. The second project is a radio astronomy survey utilizing the Arizona Radio Observatory 12 meter telescope on Kitt Peak to study molecular gas in cold star-like cores identified by the Planck all sky survey. This project provides a unique opportunity for a large group of students to get hands-on experience observing with a world-class radio observatory. These projects involve students in every single step of the process including: proposal writing to obtain telescope time on various Southern Arizona telescopes, observing at these telescopes, data reduction and analysis, managing large data sets, and presenting results at scientific meetings and in journal publications. The primary goal of these projects is to involve students in cutting-edge research early on in their undergraduate studies. These projects are designed to be continuous long term projects so that new students can easily join. New students learn from the more experienced students on the projects, creating a learner-centered environment. Independent study credit is now an option for some students working on these projects.

    The expansion of STEM education and career opportunities among underrepresented populations is a national priority. Therefore, more research is needed that examines the institutional, instructional and individual factors related to African American students' success in these fields. This dissertation study was drawn from a larger mixed-methods longitudinal study (Freeman and Winston, 2007). It utilized a concurrent embedded design of mixed methods (Creswell, 2009), to investigate faculty relationships as a source of motivation for STEM undergraduates at a HBCU. Bandura's (1986) social cognitive theory was the theoretical basis for this study. The following research questions were examined: (a) What is the nature of student-faculty relationships among STEM undergraduates attending an HBCU; (b) How does the nature of faculty student relationships vary by gender and STEM major; (c) How do student-faculty relationships influence students' persistence in STEM, self-concept of ability in mathematics and in science and grade point average; and (d) Does the influence of student-faculty relationships on self-concept of ability in mathematics and in science and grade point average vary by gender and STEM major? Freshman college students (N=167) who had a declared major in STEM fall 2009 were participants in this study. Students were predominately Black/African American (82%) and predominately female (71%). The Student-Professor Interaction Scale (SPIS) was used to measure various dimensions of student-faculty interactions (Cokley, Komarraju, Rosales, et al., 2006). The Experiences with Faculty Scale (Pace & Kuh, 1998) was used to measure the frequency of student's experiences with faculty. Self-Concept of Ability Scales in Mathematics and in Science (Marsh, 1999) was used to measure students' global perception of their abilities. An open-ended question was designed to expand and provide breadth to the quantitative results. Findings indicated that student

    2011-06-01

    The American Physiological Society (APS) and APS Council encourage the teaching of physiology at the undergraduate, graduate, and medical school levels to support the continued prominence of this area of science. One area identified by the APS Council that is of particular importance for the development of future physiologists (the "physiology pipeline") is the teaching of physiology and physiology-related topics at the undergraduate level. In this article, we describe the historical development and implementation of an undergraduate program offered through the Department of Physiology, a basic science department in the College of Medicine at the University of Arizona, culminating in a Bachelor of Science in Health Sciences degree with a major in Physiology. Moreover, we discuss the current Physiology curriculum offered at our institution and explain how this program prepares our students for successful entry into a variety of postbaccalaureate professional programs, including medical school and numerous other programs in health professions, and in graduate study in the Masters and Doctoral programs in biomedical sciences. Finally, we cover the considerable challenges that we have faced, and continue to face, in developing and sustaining a successful physiology undergraduate major in a college of medicine. We hope that the information provided on the Physiology major offered by the Department of Physiology in the College of Medicine at the University of Arizona will be helpful for individuals at other institutions who may be contemplating the development and implementation of an undergraduate program in Physiology.

  6. A look at spatial abilities in undergraduate women science majors

    Science.gov (United States)

    Lord, Thomas R.

    Contemporary investigations indicate that men generally perform significantly better in tasks involving visuo-spatial awareness than do women. Researchers have attempted to explain this difference through several hypotheses but as yet the reason for the dimorphism has not been established. Further, contemporary studies have indicated that enhancement of mental image formation and manipulation is possible when students are subjected to carefully designed spatial interventions. Present research was conducted to see if women in the sciences were as spatial perceptively accurate as their male counterparts. The researcher also was interested to find if the women that received the intervention excercises improved in their visuo-spatial awareness as rapidly as their male counterparts.The study was conducted on science majors at a suburban two year college. The population was randomly divided into groups (experimental, placebo, and control) each containing approximately the same number of men and women. All groups were given a battery of spatial perception tests (Ekstrom et al, 1976) at the onset of the winter semester and a second version of the battery at the conclusion of the semester. An analysis of variance followed by Scheffe contrasts were run on the results. The statistics revealed that the experimental group significantly outperformed the nonexperimental groups on the tests. When the differences between the mean scores for the women in the experimental group were statistically compared to those of the men in the experimental group the women were improving at a more rapid rate. Many women have the capacity to develop visuo-spatial aptitude and although they may start out behind men in spatial ability, they learn quickly and often catch up to the men's level when given meaningful visuo-spatial interventions.

    2013-04-01

    Using a randomized, between-subjects experimental design, we tested hypotheses that self-critical perfectionism would moderate the effects of subtle stereotype threat (ST) for women and students in underrepresented racial/ethnic groups who are pursuing traditional degrees in science, technology, engineering, or math (STEM). A diverse sample of freshmen students (N = 294) was recruited from 2 major universities. Students were blocked by gender and race/ethnicity and randomly assigned to experience subtle ST or no ST. Participants in the subtle ST condition were primed to consider their gender, race, and ethnicity prior to completing measures of science self-efficacy. Those in the control condition completed the measures without such priming. Controlling for prior academic performance and university context, ST priming significantly interacted (a) with self-critical perfectionism to predict coping self-efficacy scores and (b) with race/ethnicity to predict end-of-semester STEM grades. A 3-way interaction of ST priming, sex, and self-critical perfectionism also predicted students' grades in courses wherein women and men were more proportionally represented. The Sex × Self-Critical Perfectionism interaction was not significant for those in the ST group but was for those in the control group. Men in the control group had higher grade-point averages (GPAs) at low levels of self-critical perfectionism than they had at higher levels of perfectionism. In contrast, women had lower GPAs when self-critical perfectionism was low, but their GPAs were higher when self-critical perfectionism was high. The findings are discussed in terms of their implications for self-efficacy and performance in the pursuit of a STEM major.

    2017-02-01

    Employing the conceptual model developed by Comeaux and Harrison (Coll Stud Aff J 30(1):75-87, 2011), this study explored the undergraduate experience of Division I athlete STEM graduates. Data collection involved 17 in-depth interviews with former athletes at two research-intensive, public institutions. Results revealed that pre-college characteristics, involvement in purposeful STEM-related activities, and sport participation, as well as academic support and guidance within athletic departments, play important roles in shaping the experiences of athletes who earn STEM degrees. Implications for student affairs professionals, faculty, and others who frequently interact with college athletes and are committed to creating more equitable educational environments are discussed.

  17. Improving Undergraduate STEM Education: Pathways into Geoscience (IUSE: GEOPATHS) - A National Science Foundation Initiative

    Jones, B.; Patino, L. C.

    2016-12-01

    Preparation of the future professional geoscience workforce includes increasing numbers as well as providing adequate education, exposure and training for undergraduates once they enter geoscience pathways. It is important to consider potential career trajectories for geoscience students, as these inform the types of education and skill-learning required. Recent reports have highlighted that critical thinking and problem-solving skills, spatial and temporal abilities, strong quantitative skills, and the ability to work in teams are among the priorities for many geoscience work environments. The increasing focus of geoscience work on societal issues (e.g., climate change impacts) opens the door to engaging a diverse population of students. In light of this, one challenge is to find effective strategies for "opening the world of possibilities" in the geosciences for these students and supporting them at the critical junctures where they might choose an alternative pathway to geosciences or otherwise leave altogether. To address these and related matters, The National Science Foundation's (NSF) Directorate for Geosciences (GEO) has supported two rounds of the IUSE: GEOPATHS Program, to create and support innovative and inclusive projects to build the future geoscience workforce. This program is one component in NSF's Improving Undergraduate STEM Education (IUSE) initiative, which is a comprehensive, Foundation-wide effort to accelerate the quality and effectiveness of the education of undergraduates in all of the STEM fields. The two tracks of IUSE: GEOPATHS (EXTRA and IMPACT) seek to broaden and strengthen connections and activities that will engage and retain undergraduate students in geoscience education and career pathways, and help prepare them for a variety of careers. The long-term goal of this program is to dramatically increase the number and diversity of students earning undergraduate degrees or enrolling in graduate programs in geoscience fields, as well as

    2017-01-01

    Undergraduate research has become more and more integral to the functioning of higher educational institutions. At many institutions undergraduate research is conducted as capstone projects in the pure sciences, however, science faculty at some schools (including that of the authors) face the challenge of not having science majors. Even at these institutions, a select population of high achieving engineering students will often express a keen interest in conducting pure science research. Since a foray into science research provides the student the full exposure to the scientific method and scientific collaboration, the experience can be quite rewarding and beneficial to the development of the student as a professional. To this end, the authors have been working to find new contexts in which to offer research experiences to non- science majors, including a new undergraduate research class conducted by physics and chemistry faculty. An added benefit is that these courses are inherently interdisciplinary. Students in the engineering and computer science fields step into physics and chemistry labs to solve science problems, often invoking their own relevant expertise. In this paper we start by discussing the common themes and outcomes of the course. We then discuss three particular projects that were conducted with engineering students and focus on how the undergraduate research experience enhanced their already rigorous engineering curriculum.

    2013-12-01

    For more than seven years, the Council on Undergraduate Research (CUR), the primary organization supporting programs, services, and advocacy for undergraduate research, has been working with support from the NSF's Division of Undergraduate Education (DUE) to enhance, sustain, and institutionalize undergraduate research in diverse STEM disciplines and higher education settings. The Council on Undergraduate Research comprises more than 9000 individual and 670 institutional members within a divisional structure that includes geosciences, as well as 11 other thematic areas. Through its most recent grant: 'Transformational Learning through Undergraduate Research: Comprehensive Support for Faculty, Institutions, State Systems and Consortia' (NSF DUE CCLI III Award #09-20275), CUR has been collaborating with six higher education systems, each selected after a rigorous national application process in 2010 and 2011. These six systems, which collectively represent 79 individual institutions, are the Council of Public Liberal Arts Colleges (COPLAC), University of Wisconsin System (UWS), California State University System (CSU), City University of New York (CUNY), Great Lakes Colleges Association (GLCA), and Pennsylvania State System of Higher Education (PASSHE). The more than 350 participants of faculty and senior-level administrators from the six systems are engaged in shared multi-faceted and multi-year professional development experiences. Teams from each system attended customized institutes facilitated by CUR experts in 2011-2012, during which the teams developed specific action plans focused on institutionalizing undergraduate research on their campus and within their system. The systems were reconvened as a group a year after the first institute, to chart progress toward achieving their goals. Based on interviews and surveys with participants, campus teams are making substantial progress toward implementation of robust undergraduate research programs, and are making

    Cade, W. B., III

    2016-12-01

    Undergraduate Space Weather education is an important component of creating a society that is knowledgeable about space weather and its societal impacts. The space physics community has made great strides in providing academic education for students, typically physics and engineering majors, who are interested in pursuing a career in the space sciences or space weather. What is rarely addressed, however, is providing a broader space weather education to undergraduate students as a whole. To help address this gap, I have created an introductory space weather course for non-science majors, with the idea of expanding exposure to space weather beyond the typical physics and engineering students. The philosophy and methodologies used in this course will be presented, as well as the results of the first attempts to teach it. Using an approach more tailored to the non-scientist, courses such as this can be an effective means of broadening space weather education and outreach.

  1. Do Biology Students Really Hate Math? Empirical Insights into Undergraduate Life Science Majors' Emotions about Mathematics.

    2017-01-01

    Undergraduate life science majors are reputed to have negative emotions toward mathematics, yet little empirical evidence supports this. We sought to compare emotions of majors in the life sciences versus other natural sciences and math. We adapted the Attitudes toward the Subject of Chemistry Inventory to create an Attitudes toward the Subject of Mathematics Inventory (ASMI). We collected data from 359 science and math majors at two research universities and conducted a series of statistical tests that indicated that four AMSI items comprised a reasonable measure of students' emotional satisfaction with math. We then compared life science and non-life science majors and found that major had a small to moderate relationship with students' responses. Gender also had a small relationship with students' responses, while students' race, ethnicity, and year in school had no observable relationship. Using latent profile analysis, we identified three groups-students who were emotionally satisfied with math, emotionally dissatisfied with math, and neutral. These results and the emotional satisfaction with math scale should be useful for identifying differences in other undergraduate populations, determining the malleability of undergraduates' emotional satisfaction with math, and testing effects of interventions aimed at improving life science majors' attitudes toward math. © 2017 L.P.

  2. Science Café Course: An Innovative Means of Improving Communication Skills of Undergraduate Biology Majors

    Directory of Open Access Journals (Sweden)

    Anna Goldina

    2013-12-01

    Full Text Available To help bridge the increasing gap between scientists and the public, we developed an innovative two-semester course, called Science Café. In this course undergraduate biology majors learn to develop communication skills to be better able to explain science concepts and current developments in science to non-scientists. Students develop and host outreach events on various topics relevant to the community, thereby increasing interactions between budding scientists and the public. Such a Science Cafe course emphasizes development of science communication skills early, at the undergraduate level and empowers students to use their science knowledge in every day interactions with the public to increase science literacy, get involved in the local community and engage the public in a dialogue on various pressing science issues. We believe that undergraduate science majors can be great ambassadors for science and are often overlooked since many aspire to go on to medical/veterinary/pharmacy schools. However, science communication skills are especially important for these types of students because when they become healthcare professionals, they will interact with the public as part of their everyday jobs and can thus be great representatives for the field.

    2017-12-01

    Full Text Available Allogeneic stem cell transplantation (allo-SCT is the only currently available curative treatment for thalassemia major. Since it was first done in 1981, several thousand patients have benefited from it and it is now possible to offer this treatment in different parts of the world with good results. With better risk stratification and supportive care, the results of allo-SCT are now very good even in high risk patients who have significant iron overload related organ dysfunction. The improvements have mainly been in the conditioning strategies with less toxic myeloablation and management of the complications of SCT. However, several challenges remain. Transplant related complications still cause significant morbidity and mortality. There is data to show that the results of transplantation as best if done in well transfused and chelated patients <7 years of age. As only a third of the patients will have a matched related donor, there is need for investigating SCT with alternative donors. Experience with SCT for thalassemia major from matched unrelated donors or haplo-identical donors is still limited but needs further exploration. Adequate management needs to be provided post-SCT for all pre-existing complications particularly iron chelation to prevent further organ dysfunction. Systematic follow-up is needed to measure long term outcomes. The biggest challenges in India are the cost of this treatment and access to centres capable of providing this treatment. With greater support from the government, health insurance and philanthropic programs, there has been a rapid increase in the number of SCTs for thalassemia major in India. The number centres providing this treatment are also increasing making this curative treatment more widely available in India.

  4. In the foot steps of Madame Curie: A cross-case study of female undergraduate physics majors

    Science.gov (United States)

    Jaladanki, Vani Savithri

    Females are disproportionately underrepresented in STEM (science, technology, engineering, and mathematics) majors. Further, the number of females who take physics in college has declined. While female students make up 61% of graduates in biological sciences and 50% in chemistry, the proportion of women completing physics degrees is only 21% (Sawtelle, 2011). In order to improve women's access to science and engineering education, research must focus on personal and environmental factors that motivate them to select these fields (AAUW, 2010). The purpose of this study was to explore how the educational experiences of three female undergraduate physics majors contribute to their current dispositions toward, interest in, and pursuit of physics as a major at a large southern research university. This qualitative study employs symbolic interactionism (Blumer, 1969) as its methodological framework and social cognitive career theory (Lent, Brown, & Hackett, 2002) as its theoretical framework. Case study methods (Yin, 2006) were implemented to investigate the experiences of three participants. The primary sources of data included critical incident interviews (Flanagan, 1954), photographs, documents, object elicitations, and the researcher's reflections. Narrative and arts-based techniques were employed to analyze and represent data. Findings are presented as co-constructed narratives of the participants' journeys to becoming undergraduate physics majors. Three major themes emerged from the cross case analysis: carving new spaces, authoring an empowered self, and show me you care and so will I. The direct experiences of engaging with science at a young age and social persuasions of family members, teachers, and peers strongly influenced the participants' interest in and pursuit of physics. Their current dispositions to physics result from vicarious experiences with professors and peers in combination with the social persuasions of the latter. This study informs science

    2016-03-01

    The Joint Task Force on Undergraduate Physics Programs (JTUPP) was formed in response to growing awareness in the physics community that physics majors pursue a wide range of careers after graduation, with very few ending up in academia. The task force is charged with identifying the skills and knowledge that undergraduate physics degree holders should possess to be well prepared for a diverse set of careers, and providing guidance for physicists considering revising the undergraduate curriculum to improve the education of a diverse student population. Task force members represent large and small universities, professional societies, and industry, and have expertise in a broad range of areas including entrepreneurship, physics education research and systemic change in education. We reviewed employment data, surveys of employers, and reports generated by other disciplines. We also met with physicists in selected industries to get their views on the strengths and weaknesses of physics graduates, commissioned a series of interviews with recent physics graduates employed in the private sector, and identified exemplary programs that ensure that all of their students are well prepared to pursue a wide range of career paths. The findings and recommendations will be summarized.

    Homologous recombination, a central concept in biology, is defined as the exchange of DNA strands between two similar or identical nucleotide sequences. Unfortunately, undergraduate students majoring in biotechnology often experience difficulties in understanding the molecular basis of homologous recombination. In this study, we developed and implemented a 12-week laboratory course for biotechnology undergraduates in which gene targeting in Streptococcus suis was used to facilitate their understanding of the basic concept and process of homologous recombination. Students worked in teams of two to select a gene of interest to create a knockout mutant using methods that relied on homologous recombination. By integrating abstract knowledge and practice in the process of scientific research, students gained hands-on experience in molecular biology techniques while learning about the principle and process of homologous recombination. The learning outcomes and survey-based assessment demonstrated that students substantially enhanced their understanding of how homologous recombination could be used to study gene function. Overall, the course was very effective for helping biotechnology undergraduates learn the theory and application of homologous recombination, while also yielding positive effects in developing confidence and scientific skills for future work in research. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(4):329-335, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

    To improve the research quality preparation for graduate study and looking for job competition ability of undergraduates students, the education orientation objective need to be explicit. Universities need develop undergraduates' cultivation plan according to students' classification. Based on analysis of students export characteristic, there will be corresponding cultivation plan. Keep tracking study during the cultivation plan implantation process, the Curriculum system and related manage documents are revised corresponding to exist problems. There are mainly three kinds of undergraduates' career direction plan for opto-electronic major undergraduates. In addition to the vast majority university graduates opting for direct employment, nearly one third of university students choose to take part in the postgraduate entrance exams and other further education abroad, and also one-tenth choose their own businesses, university chooses are diversified. The exports are further studying as graduates, working and study abroad. Because national defense students are also recruited, the cultivation plan will be diversified to four types. For students, who go to work directly after graduation, the "Excellence engineers plan" is implemented to enhance their practice ability. For students, who will study further as graduate student, the scientific innovation research ability cultivation is paid more attention to make good foundation for their subsequent development. For students, who want to study abroad after graduation, the bilingual teaching method is introduced, and the English environment is built. We asked foreign professionals to give lectures for students. The knowledge range is extending, and the exchange and cooperation chance is provided at the same time. And the cultivation plan is revised during docking with Universities abroad. For national defense students, combat training and other defense theory courses are added to make them familiar with force knowledge. And

    Full Text Available Objective – This study investigated the information seeking behavior of undergraduate majors to gain a better understanding of where they find their research information (academic vs. non-academic sources and to determine if library instruction had any impact on the types of sources used.Methods – The study used a convenience sample of 200 students currently enrolled as undergraduates at the University of Central Florida’s College of Education. A chi square test of association was conducted to determine if the proportion of undergraduate Education majors who use academic sources as compared to non-academic sources varied depending on whether the students had attended at least one library instruction session.Results – The majority of students surveyed find their research information on the freely available Web, even though they admit that academic sources are more credible. At an alpha level of .05, types of sources used for research were not statistically significantly related to whether the student attended library instruction sessions (Pearson χ2 (1, N = 200 = 1.612, p = .447, Cramer’s V = .090.Conclusion – These results are supported by other studies that indicate that today’s college students are using freely available Internet sites much more than library resources. Little to no association appears to exist between “one-shot” library instruction sessions and the sources used by students in their research. Serious consideration needs to be given to multiple library instruction sessions and to for-credit library courses over one-shot classes.

    The proportion of women earning undergraduate geoscience degrees has remained about 40% for over a decade. Little research has investigated why women select and persist in a geoscience major. This study addresses why students major in the geosciences and why some programs are more successful at recruiting and retaining female students. We collected interview and survey data from faculty and students at six public US universities. Four sites had a low proportion of female degree recipients ( 48%). 408 students (64% female) completed surveys. Interviews were conducted with 49 faculty members and 151 students. Survey data analysis showed that interest/identity and transformative experiences were significant predictors of students' decision to major in geoscience. Institutional barriers and supports were significant predictors of confidence in the major while connection to instructor predicted students' intent to major. Analysis of pre- and post-course surveys show that students with a greater connection to instructors and students whose instructors expressed more passion for the content also reported higher levels of transformative experiences. This effect was especially pronounced for women and was a significant predictor of persistence in the major. Qualitative data show differences in departmental practices and climate between low and high female graduation sites. High sites used many student-centered approaches to teaching, had extensive opportunities for and a high number of undergraduate students involved in research, and had many opportunities for faculty-student interaction outside of class. Low sites had few of these practices. Qualitative data also showed differences in the gendered equity climate between high and low sites. High sites had more positive gender equity climates and low sites had more negative gender equity climates. At this time, we do not fully understand the causal relationships among all of these findings and higher female graduation rates

  12. Engaging Undergraduate Education Majors in the Practice of Astronomy through a Coherent Science Content Storyline Course

    For the next generation of students to learn astronomy as both a body of knowledge and a process of continually extending, refining, and revising that knowledge, teachers at all levels must learn how to engage their students in the practices of astronomy. This begins by designing science coursework for undergraduate education majors in ways that reflect how we hope they will teach their own future students. We have designed an undergraduate astronomy course for elementary education majors around a coherent science content storyline (CSCS) framework in order to investigate methods that support education majors’ uptake of astronomy practices. CSCS instruction purposefully sequences lessons in ways that make explicit the connections between science ideas in order to move students towards increasingly sophisticated explanations for a single big idea in science. We used this framework to organize our course around a series of astronomical investigations that build towards a big idea in astronomy: how the formation model explains current patterns observed in the Solar System. Each investigation helps students begin to explain observations of the Solar System from a coherent, systems-based perspective as they make choices on how to design their own data collection and analysis strategies. Through these investigations, future teachers begin to view astronomy as a process of answering scientific questions using evidence-based explanations and model-based reasoning. The course design builds on our prior research into students’ ideas about Solar System phenomena and its formation as well as students’ ideas about how astronomers carry out investigations. Preliminary results, based on analysis of student conversations during in-class investigations, science notebook entries, and scientific reports, suggest that the course helps students learn to construct evidence-based explanations while also increasing the accuracy of the explanations for astronomical phenomena. We will

    With a 1-m telescope on the University of Toledo (OH) main campus, we have initiated a grad student-undergraduate partnership to help teach the undergraduates observational methods and introduce them to research through peer mentorship. For the last 3 years, we have trained up to 21 undergraduates (primarily physics/astronomy majors) in a given academic semester, ranging from freshman to seniors. Various projects are currently being conducted by undergraduate students with guidance from graduate student mentors, including constructing three-color images, observations of transiting exoplanets, and determination of binary star orbits from echelle spectra. This academic year we initiated a large group research project to help students learn about the databases, journal repositories, and online observing tools astronomers use for day-to-day research. We discuss early inclusion in observational astronomy and research of these students and the impact it has on departmental retention, undergraduate involvement, and academic success.

    Many students entering professional degree programs, particularly M.D., Ph.D., and M.D./Ph.D., are not well prepared regarding the breadth of scientific knowledge required, communication skills, research experience, reading and understanding the scientific literature, and significant shadowing (for M.D.-related professions). In addition, physician scientists are a needed and necessary part of the academic research environment but are dwindling in numbers. In response to predictions of critical shortages of clinician investigators and the lack of proper preparation as undergraduates for these professions, the Biomedical Science (BMS) undergraduate major was created at The Ohio State University to attract incoming college freshmen with interests in scientific research and the healthcare professions. The intent of this major was to graduate an elite cohort of highly talented individuals who would pursue careers in the healthcare professions, biomedical research, or both. Students were admitted to the BMS major through an application and interview process. Admitted cohorts were small, comprising 22 to 26 students, and received a high degree of individualized professional academic advising and mentoring. The curriculum included a minimum of 4 semesters (or 2 years) of supervised research experience designed to enable students to gain skills in clinical and basic science investigation. In addition to covering the prerequisites for medicine and advanced degrees in health professions, the integrated BMS coursework emphasized research literacy as well as skills related to work as a healthcare professional, with additional emphasis on independent learning, teamwork to solve complex problems, and both oral and written communication skills. Supported by Ohio State's Department of Internal Medicine, a unique clinical internship provided selected students with insights into potential careers as physician scientists. In this educational case report, we describe the BMS

    Global health education has been expanding rapidly and several universities have created an undergraduate major degree (bachelor's degree) in global heath or global health studies. Because there are currently no national guidelines for undergraduate degrees in global health, each of these programs was developed along individual lines. To guide the development of future global health majors, we conducted a systematic review of undergraduate majors in global health. We identified eight programs and invited program directors or representatives to a symposium at the Consortium of Universities for Global Health 2016 conference to review their existing undergraduate major in global health and to discuss lessons learned and recommendations for other colleges and universities seeking to develop undergraduate degrees in global health. We noted significant diversity among the existing programs in terms of required courses, international field experiences, and thesis research projects. In this review, we describe these global health programs, their student characteristics, as well as the key educational competencies, program requirements, and core global health courses. Based on program reviews and discussions, we identify seven recommendations for the development and expansion of an undergraduate major in global health and discuss issues that have arisen in the curricular development of these programs that warrant further exploration. As the field of global health education continues to expand, following these students after graduation will be essential to ensure that the degree programs in global health both meet student needs and launch students on viable career pathways. © The American Society of Tropical Medicine and Hygiene.

    The survey aimed to capture the perceptions of undergraduate pharmacy students towards plagiarism in three major public universities in Cairo, Egypt: Helwan, Ain-Shams, and Cairo Universities. This was a paper-based self-administrated survey study. The questionnaire was validated by both content and face validation. The final survey form captured the knowledge of the students on plagiarism in terms of definitions, attitudes, and practices. Four hundred and fourteen students, 320 females and 94 males, participated in the study. There was a significant difference between the students who knew the definition of plagiarism among the three universities with p-value = .01. More than half of the participants (67%) claimed that they had no previous education or training on plagiarism. However, after being informed about plagiarism, most of them agreed that plagiarism should be regarded as stealing and a punishment. Additionally, poor study skills and the ease of copying and pasting from the Internet were identified by the majority of the students to be the leading causes of plagiarism. Pharmacy students need to be more educated on plagiarism and its consequences on research and educational ethics. Finally, more strict policies should be incorporated to monitor and control plagiarism in undergraduate sections.

  17. Snapshots of Authentic Scientific Inquiry and Teacher Preparation: Undergraduate STEM Courses, Preservice and Inservice Teachers' Experiences

    French, Debbie Ann

    In this dissertation, the researcher describes authentic scientific inquiry (ASI) within three stages of teacher preparation and development: a1) undergraduate STEM courses, b2) preservice secondary science education methods courses, and c3) inservice teacher professional development (PD). Incorporating (ASI)-- pedagogy closely modeling the research practices of scientists--is at the forefront of national science, technology, engineering, and mathematics (STEM) initiatives and the Next Generation Science Standards (NGSS). In the first of three research articles, 42 students participated in an introductory astronomy course which employed inquiry-based pedagogy. The researcher administered the Test Of Astronomy STandards (TOAST) pre/post instruction. In the second article, 56 preservice secondary science teachers completed ideal lesson plan scenarios before and after 80 hours of methods instruction. The researcher scored the scenarios using a rubrirubric developedc according to the NGSS Science and Engineering Practices, and analyzed the components from the scenarios. The third article surveyed 63 inservice STEM teachers with prior research and industry experience. The researcher highlights teacher ASI perspectives. Overall, teachers incorporated opportunities for K-20 students to use scientific instrumentation and technology to collect and analyze data, work collaboratively, and develop evidence-based conclusions. Few teachers provided opportunities for students to ask scientific questions or disseminate results, suggesting the need that teachers (at all levels) need scaffolded instruction in these areas. The researcher argues that while ASI and STEM PDs are effective for teachers, developing similar interest, on-going communities of practice may provide support for teacher to implement the ASI practices in their classrooms.

    This cross-sectional survey among Chinese university students aimed to estimate the prevalence and risk factors of major depressive disorder (MDD) among undergraduates, in order to provide basic information for the prevention and treatment of depression among the college-aged population. A total of 2,046 undergraduates were interviewed face to face using the World Health Organization Composite International Diagnostic Interview Version 3.0 (WHO-CIDI, version 3.0). Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria were used to diagnose MDD. Logistic regression was used to evaluate the associations between MDD and selected correlates. The survey response rate was 90.1% (N = 1,843). The prevalence rates of MDD were 3.9% (lifetime), 2.4% (12 months) and 0.4% (30 days). No significant gender or age differences were found in prevalence rates. No sociodemographic characteristics were related to the lifetime prevalence of MDD. In contrast, family structure and environment factors specifically being from a single-parent family (odds ratio [OR] = 2.513, confidence interval [CI] = 1.404-2.500), parents having mental problems (OR = 1.809, CI = 1.104-2.964), and physical punishment (OR = 1.789, CI = 1.077-3.001) were associated with higher lifetime prevalence of MDD. These findings showed a relatively lower prevalence of DSM-IV/CIDI MDD in this sample of Chinese undergraduates than that reported for students in other countries. However, the prevalence rate for university students was higher than that reported for general Chinese population. Family structure and socio-environmental factors in the student's family of origin significantly correlated with the lifetime prevalence of MDD. © 2015 Wiley Publishing Asia Pty Ltd.

    2013-01-01

    This report describes a unique undergraduate research and teaching collaboration between investigators at two institutions, one a relatively small, primarily undergraduate institution and the other a large, urban research-intensive university. The program incorporates three major facets. First, undergraduates participate in a weekly collaborative lab meeting involving instructors from both institutions and held via remote video. Student-led discussions and presentations dominate these meetings, and the unique format promotes novel interactions between students and instructors. Second, students carry out investigative studies centered on understanding the role extracellular pH dynamics play in regulating neuronal processing. Students carry out studies on isolated neurons and glia throughout the fall and spring semesters, and primarily use a noninvasive electrophysiological technique, termed self-referencing, for extracellular pH measurements. The technique is relatively simple and readily learned and employed by undergraduates, while still being powerful enough to provide novel and meaningful research results. The research component is expanded for several students each summer who are selected to participate in summer research with both PIs and graduate students at the major research institution. Finally results gathered during the year and over the summer are disseminated at institutional symposia, undergraduate neuroscience symposia, national society meetings, and in submitted journal manuscripts. Preliminary observations and findings over three years support the aim of this research experience; to create a productive environment that facilitates deep-level understanding of neurophysiological concepts at the undergraduate level and promotes intellectual development while cultivating an excitement for scientific inquiry in the present and future.

    One of the pillars of the US economy is a well-trained Science, Technology, Engineering and Math (STEM) workforce (National Academy of Sciences, 2007). The number of students choosing to study science and engineering has taken a dramatic decline. The percentage of those degrees conferred in SC was substantially lower than the national average and the percentage of those occupations within the SC workforce also falls below the national average, supporting the need for engaging and educational STEM programs. The NASA South Carolina Space Grant Consortium's Palmetto Research Academy (PRA) program is an immersive and integrated multidisciplinary exposure and training for undergraduate students with various backgrounds and career aspirations of critical importance to the Nation. This program offers exciting and inspiring hands-on research experiences that are aligned with NASA missions. The PRA advances NASA's research interest in areas such as aeronautics, biomedical science, sun-earth connections, planetary and Earth science. The PRA helps to develop the STEM workforce in STEM disciplines, a necessity in South Carolina. In addition, the PRA incorporates an education/outreach component, where the students engage secondary educators and students in NASA scientific and technical expertise. In 2012, the PRA had 10 research projects across the state in disciplines of mechanical and chemical engineering, bioengineering, chemistry, biogeooptical sciences, physics and astronomy and biomedical sciences. 18 undergraduates and 2 technical college students participated in authentic hands-on research mentored by leading scientists and engineers throughout the state. Examples projects include: A) Development of a series of astronomical telescopes to be mounted on a commercial human-tended suborbital rockets. The students built the instrument, including the power system and the mechanical interface, and performed function and fit testing on the XCOR Aerospace Lynx vehicle mock-up. B

  3. Advanced placement math and science courses: Influential factors and predictors for success in college STEM majors

    Science.gov (United States)

    Hoepner, Cynthia Colon

    President Obama has recently raised awareness on the need for our nation to grow a larger pool of students with knowledge in science mathematics, engineering, and technology (STEM). Currently, while the number of women pursuing college degrees continues to rise, there remains an under-representation of women in STEM majors across the country. Although research studies offer several contributing factors that point to a higher attrition rate of women in STEM than their male counterparts, no study has investigated the role that high school advanced placement (AP) math and science courses play in preparing students for the challenges of college STEM courses. The purpose of this study was to discover which AP math and science courses and/or influential factors could encourage more students, particularly females, to consider pursuing STEM fields in college. Further, this study examined which, if any, AP math or science courses positively contribute to a student's overall preparation for college STEM courses. This retrospective study combined quantitative and qualitative research methods. The survey sample consisted of 881 UCLA female and male students pursuing STEM majors. Qualitative data was gathered from four single-gender student focus groups, two female groups (15 females) and two male groups (16 males). This study examined which AP math and science courses students took in high school, who or what influenced them to take those courses, and which particular courses influenced student's choice of STEM major and/or best prepared her/him for the challenges of STEM courses. Findings reveal that while AP math and science course-taking patterns are similar of female and male STEM students, a significant gender-gap remains in five of the eleven AP courses. Students report four main influences on their choice of AP courses; self, desire for math/science major, higher grade point average or class rank, and college admissions. Further, three AP math and science courses were

    Blockus, Linda Helen

    The purpose of this study is to describe and explore some of the social and academic experiences of successful African American undergraduate science majors at predominately White universities with the expectation of conceptualizing emerging patterns for future study. The study surveyed 80 upperclass African Americans at 11 public research universities about their perceptions of the influences that affect their educational experiences and career interests in science. The mailed survey included the Persistence/ voluntary Dropout Decision Scale, the Cultural Congruity Scale and the University Environment Scale. A variety of potential influences were considered including family background, career goals, psychosocial development, academic and social connections with the university, faculty relationships, environmental fit, retention factors, validation, participation in mentored research projects and other experiences. The students' sources of influences, opportunities for connection, and cultural values were considered in the context of a research university environment and investigated for emerging themes and direction for future research. Results indicate that performance in coursework appears to be the most salient factor in African American students' experience as science majors. The mean college gpa was 3.01 for students in this study. Challenging content, time demands, study habits and concern with poor grades all serve to discourage students; however, for most of the students in this study, it has not dissuaded them from their educational and career plans. Positive course performance provided encouragement. Science faculty provide less influence than family members, and more students find faculty members discouraging than supportive. Measures of faculty relations were not associated with academic success. No evidence was provided to confirm the disadvantages of being female in a scientific discipline. Students were concerned with lack of minority role models

    Research-Based Science Education (RBSE) is a method of instruction that models the processes of scientific inquiry and exploration used by scientists to discover new knowledge. It is "research-based" in the sense that students work together on a real astronomical research project. In other words, in order to learn science, students are given the opportunity to actually do science. We present "Photo Z," a new RBSE project wherein students search for distant galaxies using data from the NOAO Deep Wide Field Survey (NDWFS). Students download FITS data files from the NDWFS cutout server. They then complete photometry of galaxies in three bands (Bw, V and I) using Polaris, a custom-made plugin written for ImageJ. The photometric color of each galaxy allows an estimate of its redshift as well as its star-formation history. Many student projects are possible. An example is to search for galaxies clustered around high-redshift quasars. An advantage of this project is that the datasets are readily available online. This project is part of an NSF CCLI grant to develop and test RBSE curricula in an undergraduate course setting. The goals of RBSE are fourfold: (1) To teach that science is a process, not just a body of knowledge; (2) To improve retention of science content by using it in a research project; (3) to improve attitudes towards STEM careers, particularly among first-year students; and (4) to develop task-driven skills, such as critical thinking and teamwork skills, that are useful in any career path. These curricula are currently being developed and tested at the University of Alaska Anchorage, Indiana University Bloomington, and Pima Community College.

    Research-Based Science Education (RBSE) is a method of instruction that models the processes of scientific inquiry and exploration used by scientists to discover new knowledge. It is "research-based" in the sense that students work together in self-guided, cooperative groups on a real astronomical research project. In other words, in order to learn science, students are given the opportunity to actually do science. We present new RBSE curricula that are part of an NSF-funded effort to develop and test such curricula in an undergraduate course setting. The goals of this curricula are fourfold: (1) To teach that science is a process, not just a body of knowledge; (2) To improve retention of science content by using it in a research project; (3) to improve attitudes towards STEM careers, particularly among first-year students; and (4) to develop task-driven skills, such as critical thinking and teamwork skills, that are useful in any career path. The research projects include projects that use astronomical imaging and spectroscopic data. The projects include: a spectroscopic study of semi-regular variable stars, a spectroscopic study of AGN, a photometric search for high-redshift galaxies in the NDWFS, a search for variable stars in open clusters, and a photometric and astrometric study of minor planets. In the projects using imaging data, students complete astrometric and photometric measurements. In the spectroscopy projects, students measure properties such continuum shape and the positions of emission and absorption lines. These curricula are currently being developed and tested at the University of Alaska Anchorage, Indiana University Bloomington, and Kenai Peninsula College.

    Humanity faces great challenges in the 21st Century to understand and limit our impact on the Earth System. To address these challenges, it is essential to understand the nature and implications of environmental change, and the complexity of the Earth system. We need to educate citizens that have the background to make new developments in understanding technical aspects of the Earth System, and to develop an understanding the interactions between society and the Earth System sufficient to make informed policy choices. Traditional disciplinary departments and majors don't fully address this; teaching and research talent in the study of the Earth System is spread over many disciplinary-oriented departments. At the University of Illinois, we are currently developing a new cross-disciplinary undergraduate major being called The Earth system, environment and Society. This development is co-sponsored by a number of departments centered in the College of Liberal Arts & Sciences (but including other departments throughout the university). Our intention is that this major will be a catalyst for bringing together the many disciplines involved in Earth System Science education. The curriculum and course for study will focus on the science and human dimensions of the Earth system, with special emphasis on the processes and issues related to the environment across a range of spatial scales from local and regional to global. Along with meeting the requirements expected of all students in a liberal arts and sciences major, students in The Earth System, Environment and Society major will be required to complete a core set of courses designed to introduce students to all of the different components of the Earth System (students will choose from course options in both the sciences and the social sciences). After completing the core courses, students will then focus their studies on one of the two options within the major, Science of the Earth System (this option will emphasize the

    Neuroscience is a rapidly expanding field, and many colleges and universities throughout the country are implementing new neuroscience degree programs. Despite the field’s growth and popularity, little data exists on the structural character of current undergraduate neuroscience programs. We collected and examined comprehensive data on existing undergraduate neuroscience programs, including academic major requirements and institution characteristics such as size, financial resources, and research opportunities. Thirty-one variables covering information about course requirements, department characteristics, financial resources, and institution characteristics were collected from 118 colleges and universities in the United States that offer a major titled “neuroscience” or “neural sciences.” Data was collected from publicly available sources (online databases, institutions’ neuroscience program websites) and then analyzed to define the average curriculum and identify associations between institution and program characteristics. Our results suggest that the average undergraduate neuroscience major requires 3 chemistry, 3 biology, 3 laboratory, 2–3 neuroscience, 1 physics, 1 math, and 2 psychology courses, suggesting that most neuroscience programs emphasize the natural sciences over the social sciences. Additionally, while 98% of institutions in our database offer research opportunities, only 31% required majors to perform research. Of note, 70% of institutions offering a neuroscience major do not have a neuroscience department, suggesting that most institutions offer neuroscience as an interdisciplinary major spanning several departments. Finally, smaller liberal arts colleges account for the majority of institutions offering a neuroscience major. Overall, these findings may be useful for informing groups interested in undergraduate neuroscience training, including institutions looking to improve or establish programs, students wanting to major in

    In China, a psychiatry major curriculum (PMC) has been implemented in select medical schools to improve the quality of undergraduate psychiatry education (UPE). Our aim was to describe this PMC and compare it with UPE in the standard Chinese clinical medicine curriculum (CMC). We also benchmarked PMC to UPE programs in the Hong Kong Special Administrative Region of China and the United States of America (USA) to determine how well it met standards of well-established programs and to highlight areas for improvement. Based on archival information, relevant literature, and communication with key informants, we described PMC and CMC in a Chinese school with both curriculums. We then compared PMC to UPE curriculums in Hong Kong and the USA. PMC provides substantially more comprehensive exposure to psychiatry than CMC, with more preclinical experiences and psychiatry clerkship course hours, greater diversity of clinical sites, and exploration of subspecialties. PMC employs a variety of teaching methods and offers mentoring for students. PMC has similar UPE preclinical content and course hours as programs in Hong Kong and the USA. PMC also provides more clinical exposure than programs in Hong Kong or the USA, although there is less variety in clinical settings. We recommend implementation of concrete measures to improve UPE in Chinese medical schools, using the PMC curriculum as a model that has been successfully implemented in China. We also recommend improvements to PMC based on comparisons with existing programs outside Mainland China.

  17. Improving scientific learning and supporting civic engagement for undergraduate non-science majors

    Science.gov (United States)

    Taylor, Alana Presley

    In prior research focusing on teaching and learning science, a definitive trend toward a new approach for undergraduate non-major science courses has emerged. Instruction should be refocused from information-transfer to giving students experiences that allow them to explore and engage in their new knowledge and find ways to integrate it into their everyday lives. One technique is to focus class material on real issues of interest and relevance. Course development that allows for civic engagement and self discovery connects learning to the lives of students and their communities. This study used a quasi-- experimental design to see if students who engaged in their learning had improved learning gains, increased motivation, and ability to relate it to their lives. The results showed that students were more motivated to connect the subject to their lives when they engaged through civic engagement projects. Techniques used in this research can be used in the future to develop science courses that focus on the needs of 21st century learners.

    Axmann, Waldemar Jay

    The Advanced Visual Quantum Mechanics project was conceived to provide computer-centered, activities-based instructional materials to upper-level undergraduate physics majors. This study implements one curriculum development cycle of research, development, and classroom testing for a single unit, The Shape and Behavior of the Wave Function, of these materials. It is designed to be a proof of concept pilot study for the project. The cycle began with an extensive review of existing research drawing on results from the general fields of cognitive science and educational research as well as more specific research regarding the use of computers in instruction and the teaching and learning of quantum mechanics. It continued with the development of written materials, a computer program, and assessment instruments all extensively based on this research. It concluded with a field test garnering an outcome of positive student and instructor attitudes and perceptions of learning gains as well as actual gains similar or superior to traditional instruction---even in the face of usage that diverged widely from that intended. Based on these results, we recommend the continuation of the Advanced Visual Quantum Mechanics project. This work would include further testing and revision of these materials, similar development and classroom testing of further materials, and new research within the context of that testing. Consideration should also be given to similar projects that address other physics subject areas.

    As part of the NSF-sponsored 'URGE (Undergraduate Research Group Experiences) to Compute' program, Dr. Matott has been collaborating with talented Math majors to explore the design of cost-effective systems to safeguard groundwater supplies from contaminated sites. Such activity is aided by a combination of groundwater modeling, simulation-based optimization, and high-performance computing - disciplines largely unfamiliar to the students at the outset of the program. To help train and engage the students, a number of interactive and graphical software packages were utilized. Examples include: (1) a tutorial for exploring the behavior of evolutionary algorithms and other heuristic optimizers commonly used in simulation-based optimization; (2) an interactive groundwater modeling package for exploring alternative pump-and-treat containment scenarios at a contaminated site in Billings, Montana; (3) the R software package for visualizing various concepts related to subsurface hydrology; and (4) a job visualization tool for exploring the behavior of numerical experiments run on a large distributed computing cluster. Further engagement and excitement in the program was fostered by entering (and winning) a computer art competition run by the Coalition for Academic Scientific Computation (CASC). The winning submission visualizes an exhaustively mapped optimization cost surface and dramatically illustrates the phenomena of artificial minima - valley locations that correspond to designs whose costs are only partially optimal.

    2011-03-01

    Seven years ago, the Strategic Programs for Innovations in Undergraduate Physics (SPIN-UP) Report produced by the National Task Force on Undergraduate Physics identified several key characteristics of thriving undergraduate physics departments including steps these departments had taken to prepare students better for careers in industry. Today statistical data from AIP shows that almost 40% of students graduating with a degree in physics seek employment as soon as they graduate. Successful undergraduate physics programs have taken steps to adapt their rigorous physics programs to ensure that graduating seniors have the skills they need to enter the industrial workplace as well as to go on to graduate school in physics. Typical strategies noted during a series of SPIN-UP workshops funded by a grant from NSF to APS, AAPT, and AIP include flexible curricula, early introduction of undergraduates to research techniques, revised laboratory experiences that provide students with skills they need to move directly into jobs, and increased emphasis on ``soft'' skills such as communication and team work. Despite significant success, undergraduate programs face continuing challenges in preparing students to work in industry, most significantly the fact that there is no job called ``physicist'' at the undergraduate level. supported by grant NSF DUE-0741560.

  1. Exploration of Factors Affecting Success of Undergraduate Engineering Majors at a Historically Black University

    Science.gov (United States)

    Igbinoba, Egheosa P.

    Blacks are underrepresented amongst persons who earn college degrees in the United States and Black males attend and complete college at a lower rate than Black females (Toldson, Fry Brown, & Sutton, 2009). According to Toldson et al. (2009), this quandary may be attributed to Black males' apathy toward education in general, waning support and ideological challenges toward Pell Grants and affirmative action, cultural incompetency on the part of the 90% White, ethnic makeup of the U.S. teaching force, and the relatively high numbers of Black males who are held back in school. In spite of the dismal statistics regarding Black male academic achievement and matriculation, there are those Black males who do participate in postsecondary education. While many studies have highlighted reasons that Black males do not achieve success in attending and persisting through college, few have adopted the anti-deficit research framework suggested by Harper (2010), identifying reasons Black males do persist in higher education. Although science, technology, engineering, and mathematics careers are identified as those most imperative to the economic competitiveness of the United States, few studies have concentrated solely on engineering majors and fewer, if any, solely on Black male engineering majors at an historically Black college and university. The aim of this study was to address an apparent gap in the literature and invoke theories for recruitment, retention, and success of Black males in engineering degree programs by employing an anti-deficit achievement framework for research of students of color in science, technology, engineering, and mathematics. Data garnered from the study included insight into participants' definitions of success, precollege experiences, factors contributing to the persistence during undergraduate study, and perceptions of attending a historically Black college and university versus a primarily White institution.

  2. Sociocultural Influences On Undergraduate Women's Entry into a Computer Science Major

    Science.gov (United States)

    Lyon, Louise Ann

    Computer science not only displays the pattern of underrepresentation of many other science, technology, engineering, and math (STEM) fields, but has actually experienced a decline in the number of women choosing the field over the past two decades. Broken out by gender and race, the picture becomes more nuanced, with the ratio of females to males receiving bachelor's degrees in computer science higher for non-White ethnic groups than for Whites. This dissertation explores the experiences of university women differing along the axis of race, class, and culture who are considering majoring in computer science in order to highlight how well-prepared women are persuaded that they belong (or not) in the field and how the confluence of social categories plays out in their decision. This study focuses on a university seminar entitled "Women in Computer Science and Engineering" open to women concurrently enrolled in introductory programming and uses an ethnographic approach including classroom participant observation, interviews with seminar students and instructors, observations of students in other classes, and interviews with parents of students. Three stand-alone but related articles explore various aspects of the experiences of women who participated in the study using Rom Harre's positioning theory as a theoretical framework. The first article uses data from twenty-two interviews to uncover how interactions with others and patterns in society position women in relation to a computer science major, and how these women have arrived at the point of considering the major despite messages that they do not belong. The second article more deeply explores the cases of three women who vary greatly along the axes of race, class, and culture in order to uncover pattern and interaction differences for women based on their ethnic background. The final article focuses on the attitudes and expectations of the mothers of three students of contrasting ethnicities and how reported

    Diversity and the underrepresentation of women, African-Americans, Hispanics and American Indians in the nation's science, technology, engineering and mathematics (STEM) fields are the subjects of the XV: A View from the Gatekeepers—STEM Department Chairs at America's Top 200 Research Universities on Female and Underrepresented Minority Undergraduate STEM Students. Annual public opinion research project commissioned by Bayer Corporation, the Bayer Facts surveys examine science education and science literacy issues. The 15th in the series and the fifth to explore diversity and underrepresentation, this research is a direct outgrowth of last year's results which found 40 percent of the country's female and underrepresented minority (URM) chemists and chemical engineers working today were discouraged from pursuing their STEM career at some point in their lives. US colleges were cited as places where this discouragement most often happened and college professors as the individuals most likely responsible. Does such discouragement still occur in American colleges today? To answer this and other questions about the undergraduate environment in which today's students make their career decisions, the survey polls 413 STEM department chairs at the nation's 200 top research universities and those that produce the highest proportion of female and URM STEM graduates. The survey also asks the chairs about their institutions track record recruiting and retaining female and URM STEM undergraduates, preparedness of these students to study STEM, the impact of traditional introductory STEM courses on female and URM students and barriers these students face pursuing their STEM degrees.

  4. Gender equity in STEM: The role of dual enrollment science courses in selecting a college major

    Science.gov (United States)

    Persons, Christopher Andrew

    A disproportionately low number of women, despite rigorous high school preparation and evidenced interest in STEM through voluntary participation in additional coursework, declare a STEM-related college major. The result of this drop in participation in STEM-related college majors is a job market flooded with men and the support of an incorrect stereotype: STEM is for men. This research seeks to assess the effects, if any, that Dual Enrollment (DE) science courses have on students' self-identified intent to declare a STEM-related college major as well as the respective perceptions of both male and female students. Self-Determination Theory and Gender Equity Framework were used respectively as the theoretical frames. High school students from six schools in two district participated in an online survey and focus groups in this mixed methods study. The results of the research identified the role the DE course played in their choice of college major, possible interventions to correct the underrepresentation, and societal causes for the stereotype.

    Stem cells are a promising source for liver repopulation after cell transplantation, but whether the adult liver contains hepatic stem cells is controversial. The purpose of this study was to characterize the properties and expression profile of major histocompatibility complex (MHC) antigens on the surface of human-derived stem cells. Human liver-derived stem cells (HLSC7) were isolated from the nontumorous tissue of a patient who underwent a resection of an hepatic hemangioendothelioma. We characterized HLSC7 using a fluorescence-activated cell sorter, polymerase chain reactions, and immunofluorescence assays. HLSC7 expressed mesenchymal but not hematopoietic stem cell markers. HLSC7 underwent osteogenic, chondrogenic, and hepatogenic differentiation when cultured in appropriate differentiation media. However, HLSC7 did not differentiate into adipocytes. In addition, HLSC7 did not express MHC class II (HLA-DP, -DQ, and -DR) antigens. However, they did express MHC class I antigens. These results suggest that human liver-derived stem cells express MHC class I antigens and thus may be rejected on transplantation. Therefore, in addition to studies on stem cell differentiation, one must overcome immunologic barriers for successful clinical application of this therapy. Copyright © 2012 Elsevier Inc.

    2014-05-01

    Little is known about postsecondary pathways and persistence among college students with an autism spectrum disorder (ASD). This study analyzed data from the National Longitudinal Transition Study-2, 2001-2009, a nationally representative sample of students in special education with an ASD who progressed from high school to postsecondary education. Findings suggest that most college students with an ASD enrolled in a 2-year community college at some point in the postsecondary careers (81%). Those in science, technology, engineering and mathematics (STEM) fields were more likely to persist in a 2-year community college and were twice as likely to transfer from a 2-year community college to a 4-year university than their peers in the non-STEM fields. College persistence rates varied by gender, race, parent education level, and college pathway and major. Educational policy implications are discussed.

    Kappler, Ulrike; Rowland, Susan L; Pedwell, Rhianna K

    2017-05-01

    Systems biology is frequently taught with an emphasis on mathematical modeling approaches. This focus effectively excludes most biology, biochemistry, and molecular biology students, who are not mathematics majors. The mathematical focus can also present a misleading picture of systems biology, which is a multi-disciplinary pursuit requiring collaboration between biochemists, bioinformaticians, and mathematicians. This article describes an authentic large-scale undergraduate research experience (ALURE) in systems biology that incorporates proteomics, bacterial genomics, and bioinformatics in the one exercise. This project is designed to engage students who have a basic grounding in protein chemistry and metabolism and no mathematical modeling skills. The pedagogy around the research experience is designed to help students attack complex datasets and use their emergent metabolic knowledge to make meaning from large amounts of raw data. On completing the ALURE, participants reported a significant increase in their confidence around analyzing large datasets, while the majority of the cohort reported good or great gains in a variety of skills including "analysing data for patterns" and "conducting database or internet searches." An environmental scan shows that this ALURE is the only undergraduate-level system-biology research project offered on a large-scale in Australia; this speaks to the perceived difficulty of implementing such an opportunity for students. We argue however, that based on the student feedback, allowing undergraduate students to complete a systems-biology project is both feasible and desirable, even if the students are not maths and computing majors. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(3):235-248, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

  1. The quadruple bottom line: the advantages of incorporating Green Chemistry into the undergraduate chemistry major

    Science.gov (United States)

    Bodner, George M.

    2017-08-01

    When the author first became involved with the Green Chemistry movement, he noted that his colleagues in industry who were involved in one of the ACS Green Chemistry Institute® industrial roundtables emphasized the take-home message they described as the "triple bottom line." They noted that introducing Green Chemistry in industrial settings had economic, social, and environmental benefits. As someone who first went to school at age 5, and has been "going to school" most days for 65 years, it was easy for the author to see why introducing Green Chemistry into academics had similar beneficial effects within the context of economic, social and environmental domains at the college/university level. He was prepared to understand why faculty who had taught traditional courses often saw the advantage of incorporating Green Chemistry into the courses they teach. What was not as obvious is why students who were encountering chemistry for the first time were often equally passionate about the Green Chemistry movement. Recent attention has been paid, however, to a model that brings clarity to the hitherto vague term of "relevance" that might explain why integrating Green Chemistry into the undergraduate chemistry classroom can achieve a "quadruple bottom-line" for students because of potentially positive effects of adding a domain of "relevance" to the existing economic, social, and environmental domains.

    The prevalence of hemoglobinopathies in Spain is increasing as a result of immigration. Thalassemia major presents with chronic hemolytic anemia that requires regular red blood cell transfusions within the first year of life. Patients with sickle cell disease suffer from chronic anemia, vasculopathy and progressive damage in almost any organ. There is decreased life expectancy in both conditions. Allogeneic hematopoietic stem cell transplantation represents the only potentially curative option. Seventeen patients (fourteen thalassemia major, and three sickle cell disease) underwent allogeneic hematopoietic stem cell transplantations. In the thalassemia group, nine donors were HLA-geno-identical siblings, two were partially matched related donors (one HLA allele mismatch), and three unrelated donors. All three patients with sickle cell disease were transplanted from HLA-geno-identical siblings. The source of stem cells was bone marrow in sixteen cases. Median patient age at transplant was six years (range: 1-16) in the thalassemia group, and twelve years (range: 8-15) in the sickle cell disease group. The graft was successful in all patients. Secondary graft rejection was observed in two thalassemia patients rendering them dependent on blood transfusions. Complete chimerism was observed in thirteen patients and, although mixed chimerism occurred in two, with all of them showing normal hemoglobin levels after transplantation and not requiring further transfusion support. Patients affected by sickle cell disease did not present with new vaso-occlusive crises, and stabilization of pulmonary and neurological function was observed. Chronic graft-versus-host disease was detected in three patients affected by thalassemia, and hypogonadotrophic hypogonadism in five patients. We conclude that for thalassemia major and sickle cell disease, allogenic hematopoietic stem cell transplantation from HLA-geno-identical siblings offers a high probability of complication-free survival

    In response to the American Association for the Advancement of Science's Vision and Change in Undergraduate Biology Education initiative, we infused authentic, plant-based research into majors' courses at a public liberal arts university. Faculty members designed a financially sustainable pedagogical approach, utilizing vertically integrated curricular modules based on undergraduate researchers' field and laboratory projects. Our goals were to 1) teach botanical concepts, from cells to ecosystems; 2) strengthen competencies in statistical analysis and scientific writing; 3) pique plant science interest; and 4) allow all undergraduates to contribute to genuine research. Our series of inquiry-centered exercises mitigated potential faculty barriers to adopting research-rich curricula, facilitating teaching/research balance by gathering publishable scholarly data during laboratory class periods. Student competencies were assessed with pre- and postcourse quizzes and rubric-graded papers, and attitudes were evaluated with pre- and postcourse surveys. Our revised curriculum increased students' knowledge and awareness of plant science topics, improved scientific writing, enhanced statistical knowledge, and boosted interest in conducting research. More than 300 classroom students have participated in our program, and data generated from these modules' assessment allowed faculty and students to present 28 contributed talks or posters and publish three papers in 4 yr. Future steps include analyzing the effects of repeated module exposure on student learning and creating a regional consortium to increase our project's pedagogical impact. © 2014 J. R. Ward et al.

    2015-10-01

    Complementary hypotheses suggest that perfectionism may (a) cause later stress (stress generation) and (b) moderate the effects of stress on subsequent outcomes (stress enhancement). The present study tested these hypotheses with a sample of 432 first-time college freshmen pursuing science, technology, engineering, and math (STEM) majors. Students completed baseline perfectionism scales and repeated measures for perceived academic stress at monthly intervals 3 times in the fall semester and 3 times in the spring semester. Course grade data from institutional records were used to calculate first-year STEM grade point average (GPA) as the distal outcome in analyses. Gender, high school GPA, SAT math scores, and university were covariates. Latent profile analyses supported adaptive, maladaptive, and nonperfectionist classes and latent class growth mixture models identified distinctly low, moderate, and high patterns of academic stress over the year. Latent transition analyses indicated that maladaptive perfectionists were likely to experience moderate or high stress (none transitioned to low stress), and adaptive perfectionists were likely to have low or moderate stress (only 4% transitioned to high stress). Women were substantially more likely than male maladaptive perfectionists to experience high stress. Low-stressed adaptive perfectionists followed by moderately stressed maladaptive perfectionists had relatively higher GPAs than other groups. Subgroups of perfectionists who transitioned to the next higher stress level had substantially lower GPAs than other groups. Overall, results were consistent with stress-generation and stress-enhancement hypotheses regarding perfectionists. Findings suggested implications for prevention and intervention with perfectionistic STEM students that should be implemented early in their college experience. (c) 2015 APA, all rights reserved).

    Distance education courses have become popular due to the increased number of commuter students as well as people already in the workforce who need further education for advancement within their careers. A graduate-level Web-based course entitled Special Topics-Poultry Food Safety Microbiology was developed from an existing senior undergraduate advanced food microbiology course in the Poultry Science Department at Texas A&M University. Conversion of standard lecture material into a distance education course can provide unique challenges to maintain comparable course content in an asynchronous manner. The overall objective for this course was to examine bacterial activities including ecology in food, animals, raw and processed meat, eggs, and human pathogenesis. Students were surveyed at the end of the class and the majority agreed that they would be willing to take the course as an online course, although they were not willing to pay an extra fee for an online course. The majority of students used the online version of the course as a supplement to the classroom rather than as a substitute.

    Taggart, Austin Dale, II

    An assessment of the introductory chemistry program for science and engineering majors at the University of Houston has been carried out. The goal of the study was to assess the program in light of its history and from the viewpoints of both the introductory chemistry students and their faculty members. Archival data for the program were reviewed over the time period 1998--2003. Included were the ethnographic data, the academic performance data of students as measured by their class grades, and the student satisfaction data as measured by their end-of-class student survey responses. Over 10,000 archival student records were reviewed. The existing end of class survey was expanded to cover a wider range of categories, including curriculum, instruction, student academic background, learning style, attitude, motivation, evaluation, and levels of effort. A survey pilot study and two research surveys were carried out; about one thousand students were surveyed in 2007--2008. By correlating the survey item responses given by students to their predicted student grades, student identified success factors were identified. Benchmarking insights from other successful programs and significant trends were provided to further benefit the program. Long interviews with four of the introductory chemistry instructors served to assess the nature of the program from the perspective of the teaching faculty. A set of 15 interview questions were posed to each faculty member, and the views of faculty embers were captured and summarized. The unintended consequences of maintaining high academic standards of success with evaluation based upon on-line problem solving for a student body with a great diversity of backgrounds in large lecture classes were high rates of failure and attrition. About half of the introductory chemistry students failed to complete their first semester course with a passing grade. Employing lecture styles that support greater student engagement, counseling underprepared

    Abstract: Researchers, policymakers, business, and industry have indicated that the United States will experience a future shortage of professionals in the Science, Technology, Engineering, and Mathematics (STEM) fields. Several strategies have been suggested to address this impending shortage, one of which includes increasing the representation of females and minorities in the STEM fields. In order to increase the representation of underrepresented students in the STEM fields, it is important to understand the motivational factors that impact underrepresented students' interest in STEM academics and extracurricular programs. Research indicates that greater confidence leads to greater interest and vice versa (Denissen et al., 2007). In this paper, the mathematics research team examined the role of practical research experience during the summer for talented minority secondary students studying in STEM fields. An undergraduate research mathematics team focused on the link between summer research and the choice of an undergraduate discipline. A Chi Square Statistical Test was used to examine Likert Scale results on the attitude of students participating in the 2006-2012 Center for Remote Sensing of Ice Sheets (CReSIS) Summer Research Programs for secondary students. This research was performed at Elizabeth City State University located in northeastern North Carolina about the factors that impact underrepresented students' choices of STEM related majors in college. Results can be used to inform and guide educators, administrators, and policy makers in developing programs and policy that support and encourage the STEM development of underrepresented students.

    Ali, Zarka Asghar

    Identifying, examining, and understanding faculty members' technological knowledge development and the process of technology adoption in higher education is a multifaceted process. Past studies have used Rogers (1995, 2003) diffusion of innovation theoretical framework to delineate the technology adoption process. These studies, however, have frequently reported the influencing factors based on the statistical analysis such as regression analysis-based approach, and have not focused on the emerging process of technology adoptions or the developing process of technological knowledge and pedagogical knowledge. A mixed method study was designed to see how faculty members acquire different technologies and develop technological knowledge that might help them adopt technologies in their classrooms and online using different pedagogies. A sample of STEM teaching faculty members with different ranks, tenure, teaching experience, and varied degree of experience in the use of educational technologies participated in the study. A survey was designed to identify internal and external factors affecting technology adoption and its effective use in different teaching activities. To elaborate survey results, the study also included class observations as well as pre- and post-observation interviews. Online classrooms used by the faculty via Blackboard learning management system, online flipped classrooms, or other websites such as Piazza were also examined for data triangulation. The findings of the study indicate that faculty members are influenced by their own professional motivations and student learning to improve their teaching methods and to enhance student interactions and learning through the use of different educational technologies. The adoption process was identified as spreading over a period of time and it looked at how faculty members' developed their technological knowledge and pedagogical knowledge. With the recognition of the social, organizational, and

  18. Dual enrollment as a factor for women transitioning into STEM majors in Montana two-year colleges

    Science.gov (United States)

    Jakes, Penny Jane

    The purpose of this non-experimental, descriptive, quantitative study was to describe the impact high school dual enrollment coursework has had on initial enrollment of women with STEM majors in Montana two-year colleges. The study was designed to find whether or not differences existed for access (initial enrollment), persistence (to third semester), and success (associate's degree, certificate, or transfer to a four-year institution within 150% of program length). The literature review highlighted the need for studies to address the issue of few women in science, technology, engineering, and mathematics (STEM) occupations. One goal of dual enrollment in Montana is to ease transitions from high school to college, including underrepresented populations such as women in STEM fields. The scope of this study was to collect, organize, and interpret data to describe the effect of that effort for women enrolling in STEM majors at two-year colleges in Montana. Baseline information established the demographics of young women who participated in dual enrollment in Montana high schools during 2007-2009. Data analysis described results using attributes of gender, dual enrollment, access, persistence, and success for those enrolled in STEM fields. Results indicated more young women than young men take advantage of dual enrollment in high school and more women than men with dual-enrollment credit initially enroll in college. More men than women major in a STEM field and more men persist and graduate within the STEM fields. Data indicated that 221 students enrolled in a Montana two-year college with DE/DC credit during 2007-2009. Of those, eight women chose STEM majors, six persisted to the third semester, and two completed. It is recommended that a mixed-methods study be conducted to give a deeper level of understanding for enrollment trends and career choice. Longitudinal studies should also be conducted as dual enrollment grows within the state of Montana. Further studies

    Full Text Available Allogeneic hematopoietic stem cell transplantation (HSCT represents a curative treatment for many patients with hematological malignant or non-malignant disorders. Evaluation of potential donors for HSCT includes a rigorous assessment of the human leukocyte antigens (HLA match status of family members, and the identification of suitable unrelated donors. Genes encoding transplantation antigens are placed both within and outside the major histocompatibility complex (MHC. The human MHC is located on the short arm of chromosome 6 and contains a series of genes encoding two distinct types of highly polymorphic cell surface glycoproteins. Donors for HSCT are routinely selected based on the level of matching for HLA-A, -B, -C, -DRB1, and -DQB1 loci. However, disease relapse, graft-versus-host-disease, and infection remain significant risk factors of morbidity and mortality. In the same breath, in high-risk patients, graft-versus-leukemia effects inherent in HLA mismatching play a substantial immunological role to limit the recurrence of post-transplant disease. The definition of a suitable donor is ever changing, shaped not only by current typing technology, but also by the specific transplant procedure. Indeed, a more complete understanding of permissible HLA mismatches and the role of Killer Immunoglobulin-like receptors’ genes increases the availability of HLA-haploidentical and unrelated donors.

    Background: The importance of increasing the number of US college students completing degrees in science, technology, engineering or mathematics (STEM) has prompted calls for research to provide a better understanding of factors related to student participation in these majors, including the impact of a student's high-school mathematics curriculum. Purpose: This study examines the relationship between various student and high-school characteristics and completion of a STEM major in college. Of specific interest is the influence of a student's high-school mathematics curriculum on the completion of a STEM major in college. Sample: The sample consisted of approximately 3500 students from 229 high schools. Students were predominantly Caucasian (80%), with slightly more males than females (52% vs 48%). Design and method: A quasi-experimental design with archival data was used for students who enrolled in, and graduated from, a post-secondary institution in the upper Midwest. To be included in the sample, students needed to have completed at least three years of high-school mathematics. A generalized linear mixed model was used with students nested within high schools. The data were cross-sectional. Results: High-school predictors were not found to have a significant impact on the completion of a STEM major. Significant student-level predictors included ACT mathematics score, gender and high-school mathematics GPA. Conclusions: The results provide evidence that on average students are equally prepared for the rigorous mathematics coursework regardless of the high-school mathematics curriculum they completed.

    Using an online trajectory analysis tool NASA, ArcGIS, Satellite and EPA in situ data, we assess whether high pollution events in Texas are primarily sourced locally or remotely. We focus satellite data that exemplify high O3 and NO2 over Texas's lower troposphere. Four day back trajectory analyses of all dates show that upper-, mid-, and lower-tropospheric air over Texas, containing high O3, is transported from the Gulf of Mexico, Southeast USA, Midwest USA, Northeast USA, the Atlantic Ocean, Pacific Ocean, Mexico, etc. Only day showed air at 1 km is sourced within Texas. Satellite data show O3 enhancements in the boundary layer and O3 and NO2 enhancements via tropospheric column profiles. These enhancements complement four-day trajectory analysis. This study provides a viable basis for more quantifiable and accurate information for developing effective air quality State Implementation Plans. STEM Impact: (i) D. Bella was an NSF-LSAMP undergraduate research mentee with me at Medgar Evers College-CUNY; she received a B.S. in Environmental Science (and a Chemistry Minor) and is now a Ph.D. graduate student at University at Albany's School of Public Health.

    A 49-year-old white man with blood group AB, D+ was found to have alloanti-Jk(a) and -K when he developed a delayed hemolytic transfusion reaction before allogeneic hematopoietic stem cell transplant (HSCT). Given that his stem cell donor was blood group O, D+, Jk(a+), K-, rituximab was added to his conditioning regimen of fludarabine and melphalan to prevent hemolysis of engrafting Jk(a+) donor red blood cells. The patient proceeded to receive a peripheral blood stem cell transplant from a matched unrelated donor with no adverse events. To our knowledge, this is the first case of successful management of major non-ABO incompatibility caused by anti-Jk(a) in a patient receiving an allogeneic HSCT reported in the literature.

  8. Transfer students in STEM majors at a Midwestern University: Academic and social involvement factors that influence student success

    Science.gov (United States)

    Lopez, Carlos

    There is soon-to-be a shortage of qualified U.S. workers in science, technology, engineering, and mathematics (STEM). As a result, many science-related jobs are being filled by technically-skilled foreign workers. If the U.S wants to maintain its global economic leadership, then it must ensure a continuous growth of highly-trained individuals in STEM disciplines. Therefore, American institutions of higher education, including community colleges, must identify potential factors that contribute to the lack of interest in STEM majors, as well as the low rate of success of students who enter STEM majors but struggle to finish their degrees. The purpose of this study was to ascertain the perceptions of community college transfer students who are pursuing bachelor degrees in STEM majors at Iowa State University (ISU). What were their transfer experiences and what influenced their academic success in STEM. Participants were encouraged to share their transfer experiences while at the community college as well as their experiences on the ISU campus. They were also asked about their level of academic involvement, their relationships with faculty, and their participation in peer group activities prior to and after transferring. The research design included both quantitative and qualitative components, which provided an in-depth look at the experiences of STEM non-engineering and engineering students. Quantitative data include students' background characteristics, demographic information, and college activities at the community college and ISU. Qualitative data were used to illuminate students' overall transfer experience and their successful journey in STEM fields. The combination of quantitative and qualitative methods allowed a better understanding of the strategies students put into practice once they transfer from a community college to a four-year institution in pursuit of a STEM bachelor's degree. The results of this study suggest that there is an association among the

  9. Major Gene for Field Stem Rust Resistance Co-Locates with Resistance Gene Sr12 in 'Thatcher' Wheat.

    Directory of Open Access Journals (Sweden)

    Colin W Hiebert

    Full Text Available Stem rust, caused by Puccinia graminis (Pgt, is a damaging disease of wheat that can be controlled by utilizing effective stem rust resistance genes. 'Thatcher' wheat carries complex resistance to stem rust that is enhanced in the presence of the resistance gene Lr34. The purpose of this study was to examine APR in 'Thatcher' and look for genetic interactions with Lr34. A RIL population was tested for stem rust resistance in field nurseries in Canada, USA, and Kenya. BSA was used to find SNP markers associated with reduced stem rust severity. A major QTL was identified on chromosome 3BL near the centromere in all environments. Seedling testing showed that Sr12 mapped to the same region as the QTL for APR. The SNP markers were physically mapped and the region carrying the resistance was searched for sequences with homology to members of the NB-LRR resistance gene family. SNP marker from one NB-LRR-like sequence, NB-LRR3 co-segregated with Sr12. Two additional populations, including one that lacked Lr34, were tested in field nurseries. NB-LRR3 mapped near the maximum LOD for reduction in stem rust severity in both populations. Lines from a population that segregated for Sr12 and Lr34 were tested for seedling Pgt biomass and infection type, as well as APR to field stem rust which showed an interaction between the genes. We concluded that Sr12, or a gene closely linked to Sr12, was responsible for 'Thatcher'-derived APR in several environments and this resistance was enhanced in the presence of Lr34.

The purpose of this study was to examine APR in ‘Thatcher’ and look for genetic interactions with Lr34. A RIL population was tested for stem rust resistance in field nurseries in Canada, USA, and Kenya. BSA was used to find SNP markers associated with reduced stem rust severity. A major QTL was identified on chromosome 3BL near the centromere in all environments. Seedling testing showed that Sr12 mapped to the same region as the QTL for APR. The SNP markers were physically mapped and the region carrying the resistance was searched for sequences with homology to members of the NB-LRR resistance gene family. SNP marker from one NB-LRR-like sequence, NB-LRR3 co-segregated with Sr12. Two additional populations, including one that lacked Lr34, were tested in field nurseries. NB-LRR3 mapped near the maximum LOD for reduction in stem rust severity in both populations. Lines from a population that segregated for Sr12 and Lr34 were tested for seedling Pgt biomass and infection type, as well as APR to field stem rust which showed an interaction between the genes. We concluded that Sr12, or a gene closely linked to Sr12, was responsible for ‘Thatcher’-derived APR in several environments and this resistance was enhanced in the presence of Lr34. PMID:27309724

    Historically, racial and ethnic minority students from low income backgrounds have faced unequal access to colleges and universities. Recently, both K-12 and higher education institutions, specifically the University of California, in response to Proposition 209, have made efforts to increase access and opportunities for all students. Similarly, female minority students are underrepresented in selected science, technology, engineering and math (STEM) majors and careers. Using a qualitative research design, this study investigates how first generation, low income, underrepresented minority students who graduated from an innovative college preparatory high school enact coping strategies that they were explicitly taught to achieve success within the context of university science and math courses. The presence of a unique, college-prep high school on the campus of UC San Diego, which accepts exclusively low-income students through a randomized lottery system, creates an unusual opportunity to study the transition from high school to college for this population, a cohort of underrepresented students who were taught similar academic coping strategies for success in college. This study aims to understand how students develop their college-going, academic identities within the context of their colleges and universities. Furthermore, this study intends to understand the phenomenon of "transition to college" as a lived experience of first-generation, low income, minority students, who all share a similar college preparatory, high school background. The main research questions are: (1) How do underrepresented students experience the transition from a college preparatory high school to college? (2) How are students developing their college-going, academic identities in the context of their educational institutions? and (3) What factors support or constrain student participation and success in college science courses? Twenty-eight students participated in this study. Based on

    The purpose of this study was to explore the perceptions of Hispanic first-generation college students (FGCSs) who made the immediate transition from high school into a science, technology, engineering, or mathematics (STEM) field of study at a public, four-year higher education institution in South Florida. The conceptual foundation for this study was Bourdieu's (1986) Theory of Cultural Capital and Bandura's (1977) Theory of Self-Efficacy. Ten purposefully sampled participants engaged in face-to-face interviews or Skye/FaceTime with a total maximum duration of 90 minutes including member checking. As a result of the data collection and analysis, a total of six themes emerged: lack of cultural capital transmitted by cultural activities, high levels of parental encouragement/involvement, high levels of cultural capital transmitted through formal schooling, high levels of self-efficacy, beliefs of personal success, and overcoming challenges. Theme one evoked two subthemes: challenges and family life. Theme two produced two subthemes: home culture and cultural values. Theme three formed two subthemes: course rigor and teacher-student communication/relationships. Theme four conjured three subthemes: mindset, vicarious experiences, and home discourse. Theme five yielded two subthemes: verbal persuasion and performance accomplishments/mastery experiences. Finally, theme six formed one subtheme: biases. Findings from this study may benefit the literature on the lack of representation of Hispanic FGCSs in STEM fields in higher education and may serve as a starting point for the conception of programs and initiatives to spark and sustain student interest in STEM, and ultimately influence a student's decision to pursue a STEM degree in higher education.

    Breeding for solid-stemmed durum (Triticum turgidum L. var durum) and common wheat (Triticum aestivum L.) cultivars is one strategy to minimize yield losses caused by the wheat stem sawfly (Cephus cinctus Norton). Major stem-solidness QTL have been localized to the long arm of chromosome 3B in both wheat species, but it is unclear if these QTL span a common genetic interval. In this study, we have improved the resolution of the QTL on chromosome 3B in a durum (Kofa/W9262-260D3) and common wheat (Lillian/Vesper) mapping population. Coincident QTL (LOD = 94–127, R2 = 78–92%) were localized near the telomere of chromosome 3BL in both mapping populations, which we designate SSt1. We further examined the SSt1 interval by using available consensus maps for durum and common wheat and compared genetic to physical intervals by anchoring markers to the current version of the wild emmer wheat (WEW) reference sequence. These results suggest that the SSt1 interval spans a physical distance of 1.6 Mb in WEW (positions 833.4–835.0 Mb). In addition, minor QTL were identified on chromosomes 2A, 2D, 4A, and 5A that were found to synergistically enhance expression of SSt1 to increase stem-solidness. These results suggest that developing new wheat cultivars with improved stem-solidness is possible by combining SSt1 with favorable alleles at minor loci within both wheat species. PMID:28399136

    Throughout the world, the labor market is clearly gender segregated. More research is needed to explain women's lower interest in STEM (Science, Technology, Engineering and Mathematics) majors and particularly to explain men's lower interest in HEED (Health care, Elementary Education, and the Domestic spheres) majors. We tested self-efficacy (competence beliefs) and social belongingness expectations (fitting in socially) as mediators of gender differences in interest in STEM and HEED majors in a representative sample of 1327 Swedish high school students. Gender differences in interest in STEM majors strongly related to women's lower self-efficacy for STEM careers and, to a lesser degree, to women's lower social belongingness expectations with students in STEM majors. Social belongingness expectations also partly explained men's lower interest in HEED majors, but self-efficacy was not an important mediator of gender differences in interest in HEED. These results imply that interventions designed to lessen gender segregation in the labor market need to focus more on the social belongingness of students in the gender minority. Further, to specifically increase women's interest in STEM majors, we need to counteract gender stereotypical competence beliefs and assure women that they have what it takes to handle STEM careers.

    Podocalyxin (PC) was first identified as a heavily sialylated transmembrane protein of glomerular podocytes. Recent studies suggest that PC is a remarkable glycoconjugate that acts as a universal glyco-carrier. The glycoforms of PC are responsible for multiple functions in normal tissue, human cancer cells, human embryonic stem cells (hESCs), and human induced pluripotent stem cells (hiPSCs). PC is employed as a major pluripotent marker of hESCs and hiPSCs. Among the general antibodies for human PC, TRA-1-60 and TRA-1-81 recognize the keratan sulfate (KS)-related structures. Therefore, It is worthwhile to summarize the outstanding chemical characteristic of PC, including the KS-related structures. Here, we review the glycoforms of PC and discuss the potential of PC as a novel KS proteoglycan in undifferentiated hESCs and hiPSCs.

    Today's science classrooms are addressing the need for non-scientists to become scientifically literate. A key aspect includes the recognition of science as a process for discovery. This process relies upon interdisciplinary collaboration. We designed a semester-long collaborative exercise that allows science majors taking a general microbiology course and non-science majors taking an introductory environmental science course to experience collaboration in science by combining their differing skill sets to identify microorganisms enriched in Winogradsky columns. These columns are self-sufficient ecosystems that allow researchers to study bacterial populations under specified environmental conditions. Non-science majors identified phototrophic bacteria enriched in the column by analyzing the signature chlorophyll absorption spectra whereas science majors used 16S rRNA gene sequencing to identify the general bacterial diversity. Students then compiled their results and worked together to generate lab reports with their final conclusions identifying the microorganisms present in their column. Surveys and lab reports were utilized to evaluate the learning objectives of this activity. In pre-surveys, nonmajors' and majors' answers diverged considerably, with majors providing responses that were more accurate and more in line with the working definition of collaboration. In post-surveys, the answers between majors and nonmajors converged, with both groups providing accurate responses. Lab reports showed that students were able to successfully identify bacteria present in the columns. These results demonstrate that laboratory exercises designed to group students across disciplinary lines can be an important tool in promoting science education across disciplines.

    Objective: To share the preliminary data on stem cell transplantation in Pakistan. Results: Engraftment was achieved in all patients except one who required a second dose of bone marrow graft on day +21. Median time to achieve absolute neutrophil count of > 0.5 x 10/sup 9/ /l was 9.0 days (range 8 - 31 days) and platelet count of > 20 x 10/sup 9/ /l was 14 days (12 - 35 days). Acute GVHD was seen in 3 patients, one patient had grade IV gut GVHD; another patient had grade III gut GVHD while third patient had grade II skin GVHD. Median hospital stay was 29 days. Six patients were well and transfusion independent 3 to 36 months post transplant. One episode of primary graft failure required a second dose of bone marrow harvest. Another episode of graft rejection received two doses of donor lymphocytes infusion. There were 4 deaths due to grade IV gut GVHD because of uncontrolled systemic Candida infection and one due to hepatic veno-occlusive (VOD) disease. Conclusion: Allogeneic peripheral blood stem cell transplantation can be safely and economically carried out in Pakistan. Although there had been 4 deaths during 36 months follow-up, with increasing understanding and experience the outcome is expected to improve. (author)

    Green stem disorder (GSD) is one of the most serious syndromes affecting soybean (Glycine max) cultivation in Japan. In GSD, stems remain green even when pods mature. When soybean plants develop GSD, seed surfaces are soiled by tissue fluid and seed quality is deteriorated during machine harvesting. We performed quantitative trait locus (QTL) analyses for GSD insensitivity using recombinant inbred lines (RILs; n = 154) derived from a cross between an insensitive line ('Touhoku 129') and a sensitive leading cultivar ('Tachinagaha') during a 6-year evaluation. Three effective QTLs were detected. The influences of these QTLs were in the following order: qGSD1 (LG_H) > qGSD2 (LG_F) > qGSD3 (LG_L). At these three QTLs, 'Touhoku 129' genotypes exhibited more GSD insensitivity than 'Tachinagaha' genotypes. The lower incidence of GSD for 'Touhoku129' was attributable primarily to these three QTLs because RILs harboring a 'Touhoku 129' genotype at the three QTLs exhibited a GSD incidence similar to that of 'Touhoku 129.' Although a limitation of this study is that only one mapping population was evaluated, this QTL information and the flanking markers of these QTLs would be effective tools for resolving GSD in soybean breeding programs.

  5. Learning Quality Assurance/Quality Control Using U.S. EPA Techniques. An Undergraduate Course for Environmental Chemistry Majors

    Libes, Susan M.

    1999-12-01

    Chemical analyses should always be accompanied by activities that ensure and document quality control (QC). An undergraduate course in environmental analysis is a practical point at which to teach this, as the U.S. EPA has developed a standard set of QC activities. Such a course should be a requirement for all environmental chemistry programs because the collection of reliable and defensible data is central to regulatory monitoring work as well as modeling efforts and risk assessment. In the environmental realm, QC includes activities associated with sampling, sample preservation and storage, method validation, and analysis involving solids, liquids, and gases. Students should be led to discover the need for QC by first performing analyses with little guidance. This is followed by a class discussion in which they critique their data. Once convinced of the value of QC, students learn specific techniques by performing an Initial Demonstration of Capability for a relatively simple analysis in which they perform an instrumental calibration, determine method detection limits, and demonstrate adequate precision and accuracy. Particular focus is put on the use of spreadsheets for generating forms, producing control charts, and performing statistical tests. A variety of analytical methods are covered, including atomic and molecular spectrometry, ion selective electrodes, and gas chromatography.

    This study investigated the dynamics of parasitism, host plant resistance, pathogens, and predation on the demography of wheat stem sawfly, Cephus cinctus Norton (Hymenoptera: Cephidae), developing in susceptible (hollow stem) and resistant (solid stem) wheat hosts. This study is also the first to investigate the prevalence and impact of cannibalism on wheat stem sawfly mortality. Wheat stem sawflies were sampled in two commercial wheat fields over 4 yr from the egg stage through adult emergence, and multiple decrement life tables were constructed and analyzed. Cannibalism, host plant resistance, or unknown factors were the most prevalent factors causing egg mortality. Summer mortality of prediapause larvae ranged from 28 to 84%, mainly due to parasitism by Bracon cephi (Gahan) and Bracon lissogaster Muesebeck, cannibalism, and host plant resistance. Winter mortality ranged from 6 to 54% of the overwintering larvae, mainly due to unknown factors or pathogens. Cannibalism is a major cause of irreplaceable mortality because it is absolute, with only a single survivor in every multiple infested stem. Subsequent to obligate cannibalism, mortality of feeding larvae due to host plant resistance was lower in hollow stem wheat than in solid stem wheat. Mortality from host plant resistance was largely irreplaceable. Irreplaceable mortality due to parasitoids was greater in hollow stem wheat than in solid stem wheat. Host plant resistance due to stem solidness and parasitism in hollow stems cause substantial mortality in populations of actively feeding larvae responsible for all crop losses. Therefore, enhancing these mortality factors is vital to effective integrated pest management of wheat stem sawfly. © The Authors 2015.

    The purpose of the current study was to determine personality types and demographic characteristics of professional music educators and music therapists. The researchers also sought to determine if personality types of professionals were consistent with undergraduate majors in those fields and personal characteristics as suggested by The Music Education National Conference (MENC) and the American Music Therapy Association (AMTA). The research of Steele and Young (2008) found strong similarities and some differences between undergraduate music education and music therapy students. The possibility that basic types extend across the life span may strengthen understanding of job satisfaction, stress, burn out and other factors affecting retention. Participants were a voluntary convenience sample of 253 music educators (n=110) and music therapists (n=143). The highest preference for music educators was Extrovert-Intuition-Feeling-Judgment (ENFJ) and the highest preference for music therapists was Introvert-Intuition-Feeling-Judgment (INFJ). The difference in the collective type of each group was their "outlook on life", which was either Extrovert or Introvert. However, both groups were the same in their secondary type functions of "NFJ". A comparison of findings with the Steele and Young (2008) study suggested small changes in personality type over time. Caution must be exercised in generalizing findings; however this descriptive investigation may serve as the basis for future studies, which should help foster a stable work force in these professions.

    Summary Neural stem cells (NSCs) reside in a hypoxic microenvironment within the brain. However, the crucial transcription factors (TFs) that regulate NSC biology under physiologic hypoxia are poorly understood. Here we have performed gene set enrichment analysis (GSEA) of microarray datasets from hypoxic versus normoxic NSCs with the aim of identifying pathways and TFs that are activated under oxygen concentrations mimicking normal brain tissue microenvironment. Integration of TF target (TFT) and pathway enrichment analysis identified the calcium-regulated TF NFATc4 as a major candidate to regulate hypoxic NSC functions. Nfatc4 expression was coordinately upregulated by top hypoxia-activated TFs, while NFATc4 target genes were enriched in hypoxic NSCs. Loss-of-function analyses further revealed that the calcineurin-NFATc4 signaling axis acts as a major regulator of NSC self-renewal and proliferation in vitro and in vivo by promoting the expression of TFs, including Id2, that contribute to the maintenance of the NSC state.

  10. Gender Differences in Self-Efficacy and Sense of Class and School Belonging for Majors in Science, Technology, Engineering, and Mathematics (STEM) Disciplines

    Science.gov (United States)

    Hogue, Barbara A.

    Research into women's underrepresentation in science, technology, engineering, and mathematics (STEM) disciplines has become a topic of interest due to the increasing need for employees with technical expertise and a shortage of individuals to fill STEM jobs. The discrepancy in women's representation between STEM and other fields cannot adequately be explained by factors such as women's need to balance work and family (medicine and law are both extremely demanding careers), women's fear of competition (admissions into medical and law schools are highly competitive), or women's inability to excel in science (e.g., entry into medicine requires excellent achievement in the basic sciences). The purpose of this study is to gain a deeper understanding of the role and/or impact a sense of belonging has inside and outside of STEM classrooms. Research questions focused on the role and/or impact of belonging contributes to students' self-efficacy beliefs as a STEM major. Bandura's self-efficacy theory serves as the theoretical framework. Data sources include close-ended surveys of 200 sophomore- and junior-level college students majoring in a STEM discipline. A quantitative exploratory approach allowed participants' responses to be analyzed using both correlation and multiple regression analyses to understand whether a student's sense of belonging is associated with his or her self-efficacy beliefs. Findings suggested that positive support systems impact students' self-efficacy and play a role in fostering students' motivation and decision to major in STEM disciplines. This study contributes to positive social change by providing empirical evidence faculty and administrators may use to promote university-based STEM support programs reflecting the impact belonging has on students' self-efficacy and potentially increasing the number of students majoring in STEM disciplines.

    Lyons, Daniel J.

    This study explored the impact of a novel inquiry-based astronomy laboratory curriculum designed using the Backwards Faded Scaffolding inquiry teaching framework on non-science majoring undergraduate students' views of the nature of scientific inquiry (NOSI). The study focused on two aspects of NOSI: The Distinction between Data and Evidence (DvE), and The Multiple Methods of Science (MMS). Participants were 220 predominately non-science majoring undergraduate students at a small, doctoral granting, research-extensive university in the Rocky Mountain region of the United States. The student participants were enrolled in an introductory astronomy survey course with an associated laboratory section and were selected in two samples over consecutive fall and spring semesters. The participants also included four of the graduate student instructors who taught the laboratory courses using the intervention curriculum. In the first stage, student participant views of NOSI were measured using the VOSI-4 research instrument before and after the intervention curriculum was administered. The responses were quantified, and the distributions of pre and posttest scores of both samples were separately analyzed to determine if there was a significant improvement in understanding of either of the two aspects of NOSI. The results from both samples were compared to evaluate the consistency of the results. In the second stage, the quantitative results were used to strategically design a qualitative investigation, in which the four lab instructors were interviewed about their observations of how the student participants interacted with the intervention curriculum as compared to traditional lab activities, as well as their suggestions as to how the curriculum may or may not have contributed to the results of the first stage. These interviews were summarized and analyzed for common themes as to how the intervention curriculum influenced the students' understandings of the two aspect of

Ogbu’s (1998 Cultural-Ecological Theory of Minority School Performance, a theoretical framework, posits that the manner by which a group achieves minority status, coupled with community and family educational values, impacts academic achievement. Immigrants, voluntary minorities, perform better academically than involuntary minorities (nonimmigrants because they are more accepting of and more likely to adapt to the White middle-class norms upon which schools in the United States are based (Ogbu, 1994, 2004. While the data overall are positive for the sample, when viewed by ethnic group, it was evident the African and Caribbean students are more academically integrated to campus than African American students. The African students, more so than any other ethnic group, are connecting, interacting, and forming relationships with faculty outside of the classroom; conversely, African American students in this study reported having the least amount of effective connections with faculty. This research study found that for the Black male STEM students in this project (a their families are a pivotal force, (b academic experiences vary across ethnicities, (c faculty mediate student success, and (d there is a lack of interactions between ethnic groups (Black Distance on campus.

    Theobald, Roddy; Freeman, Scott

    2014-01-01

    Although researchers in undergraduate science, technology, engineering, and mathematics education are currently using several methods to analyze learning gains from pre- and posttest data, the most commonly used approaches have significant shortcomings. Chief among these is the inability to distinguish whether differences in learning gains are due to the effect of an instructional intervention or to differences in student characteristics when students cannot be assigned to control and treatment groups at random. Using pre- and posttest scores from an introductory biology course, we illustrate how the methods currently in wide use can lead to erroneous conclusions, and how multiple linear regression offers an effective framework for distinguishing the impact of an instructional intervention from the impact of student characteristics on test score gains. In general, we recommend that researchers always use student-level regression models that control for possible differences in student ability and preparation to estimate the effect of any nonrandomized instructional intervention on student performance.

Embracing SCCT as the foundation of this project, the dissertation intended to gather data from these young men to develop insight into how and in what ways their self-efficacy throughout the semester was influenced by their first science course, and changing their outlook on Science, Technology, Engineering, and Mathematics (STEM) careers while in school and after graduation. To a small number of freshman African American male students who have declared themselves STEM majors, I utilized a qualitative study investigating this phenomenon. The major findings detailed themes that affected these young men including concerns about mathmatics preparation, isolation, balance, microagression, and help-seeking. Results indicate that there was an impact on the confidence, achievement, and goal setting for these young men due to these factors and that social cognitive career theory was an appropriate framework from which to test these questions.

    Although few studies have examined the direct effect of stress shielding on clinical outcomes, periprosthetic bone loss due to stress shielding is still an issue of concern, especially when physicians perform uncemented total hip arthroplasty (THA) in younger patients. Differences in femoral stem design may affect the degree of postoperative stress shielding. Therefore, the characteristics of the behavior for stress shielding of each type of femoral stem should be determined. This study compares differences in bone mineral density (BMD) change in the femur after primary THA between 3 major types of uncemented stems. Among a total of 89 hips, 26 hips received THA with a fit-and-fill type stem (VerSys Fiber Metal MidCoat; Zimmer, Inc, Warsaw, IN), 32 hips received a tapered rectangular Zweymüller-type stem (SL-Plus; Smith & Nephew Inc, Memphis, TN), and 31 received a tapered wedge-type stem (Accolade TMZF; Stryker Orthopaedics, Mahwah, NJ). BMD measurements were performed with a HOLOGIC Discovery device (Hologic Inc, Waltham, MA). BMD in the medial-proximal femur was maintained for 3 years after THA in the group with the tapered wedge-type stem. BMD in the lateral-proximal femur was maintained for 3 years after THA in the group with the Zweymüller-type stem. There were no significant differences in the Harris Hip Score among the 3 stem groups preoperatively and 1, 2, and 3 years after surgery. There are clear differences in postoperative BMD loss of the proximal femur among these 3 commonly used uncemented stems. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available This two-year study describes the assessment of student learning gains arising from participation in a year-long curriculum consisting of a classroom undergraduate research experience (CURE embedded into second-year, major core Genetics and Cellular and Molecular Biology (CMB laboratory courses. For the first course in our CURE, students used micro-array or RNAseq analyses to identify genes important for environmental stress responses by Saccharomyces cerevisiae. The students were tasked with creating overexpressing mutants of their genes and designing their own original experiments to investigate the functions of those genes using the overexpression and null mutants in the second CURE course. In order to evaluate student learning gains, we employed three validated concept inventories in a pretest/posttest format and compared gains on the posttest versus the pretest with student laboratory final grades. Our results demonstrated that there was a significant correlation between students earning lower grades in the Genetics laboratory for both years of this study and gains on the Genetics Concept Assessment (GCA. We also demonstrated a correlation between students earning lower grades in the Genetics laboratory and gains on the Introductory Molecular and Cell Biology Assessment (IMCA for year 1 of the study. Students furthermore demonstrated significant gains in identifying the variable properties of experimental subjects when assessed using the Rubric for Experimental (RED design tool. Results from the administration of the CURE survey support these findings. Our results suggest that a year-long CURE enables lower performing students to experience greater gains in their foundational skills for success in the STEM disciplines.

    Major depression is a significant contributor to the global burden of disease, and its pathophysiology is largely unknown. The serotonin hypothesis is, however, the model with most supporting data, although the details are only worked out to some extent. Recent clinical imaging measurements indeed imply a role in major depressive disorder (MDD) for the inhibitory serotonin autoreceptor 5-hydroxytryptamine1B (5-HT1B). The aim of the current study was to examine 5-HT1B receptor binding in the brain of MDD patients before and after psychotherapy. Ten patients with an ongoing untreated moderate depressive episode were examined with positron emission tomography (PET) and the 5-HT1B receptor selective radioligand [(11)C]AZ10419369, before and after treatment with internet-based cognitive behavioural therapy. All of the patients examined responded to treatment, and 70% were in remission by the time of the second PET measurement. A statistically significant 33% reduction of binding potential (BPND) was found in the dorsal brain stem (DBS) after treatment. No other significant changes in BPND were found. The DBS contains the raphe nuclei, which regulate the serotonin system. This study gives support for the importance of serotonin and the 5-HT1B receptor in the biological response to psychological treatment of MDD. Copyright © 2014 Elsevier Ireland Ltd.

    Full Text Available Impatiens balsamina L. (Balsaminaceae, an annual herb found throughout China, has been extensively used in traditional Chinese medicine (TCM. However, our knowledge regarding the adverse effects of I. balsamina in vivo is very limited. In this present study, the nematode Caenorhabditis elegans model was employed to fully assess the adverse effects of hydroalcoholic (EtOH 55% extracts of I. balsamina stems (HAEIBS in vivo. After exposure to 10 mg/mL HAEIBS, the major organism-level endpoints of C. elegans of percent survival, frequency of head thrash and body bends, and reproduction had decreased by 24%, 30%, and 25%, respectively. The lifespan of C. elegans was also greatly reduced after HAEIBS exposure compared to the controls. The active compounds in HAEIBS were separated using high speed countercurrent chromatograph (HSCCC and characterized by high performance liquid chromatography (HPLC and nuclear magnetic resonance (NMR. Two compounds, lawsone and 2-methoxy-1,4-naphthoquinone (MNQ, and their adverse effects were then more thoroughly detailed in this study. It was found that lawsone is the major toxin in HAEIBS with a higher toxicity than MNQ in terms of negative impact on C. elegans mortality, locomotion, reproduction, and lifespan. Our data also suggests that the C. elegans model may be useful for assessing the possible toxicity of other Chinese medicines, plant extracts, and/or compounds.

    Allogeneic mesenchymal stem cells (MSCs) are a promising cell source for treating musculoskeletal injuries in horses. Controversy exists, however, over whether major histocompatibility complex (MHC)-mismatched MSCs are recognised by the recipient immune system and targeted for death by a cytotoxic antibody response. To determine if cytotoxic anti-MHC antibodies generated in vivo following MHC-mismatched MSC injections are capable of initiating complement-dependent cytotoxicity of MSCs. Experimental controlled study. Antisera previously collected at Days 0, 7, 14 and 21 post-injection from 4 horses injected with donor MHC-mismatched equine leucocyte antigen (ELA)-A2 haplotype MSCs and one control horse injected with donor MHC-matched ELA-A2 MSCs were utilised in this study. Antisera were incubated with ELA-A2 MSCs before adding complement in microcytotoxicity assays and cell death was analysed via eosin dye exclusion. ELA-A2 peripheral blood leucocytes (PBLs) were used in the assays as a positive control. Antisera from all 4 horses injected with MHC-mismatched MSCs contained antibodies that caused the death of ELA-A2 haplotype MSCs in the microcytotoxicity assays. In 2 of the 4 horses, antibodies were present as early as Day 7 post-injection. MSC death was consistently equivalent to that of ELA-A2 haplotype PBL death at all time points and antisera dilutions. Antisera from the control horse that was injected with MHC-matched MSCs did not contain cytotoxic ELA-A2 antibodies at any of the time points examined. This study examined MSC death in vitro only and utilized antisera from a small number of horses. The cytotoxic antibody response induced in recipient horses following injection with donor MHC-mismatched MSCs is capable of killing donor MSCs in vitro. These results suggest that the use of allogeneic MHC-mismatched MSCs must be cautioned against, not only for potential adverse events, but also for reduced therapeutic efficacy due to targeted MSC death. © 2016 The

  4. The experiences of female high school students and interest in STEM: Factors leading to the selection of an engineering or computer science major

    Genoways, Sharon K.

    STEM (Science, Technology, Engineering and Math) education creates critical thinkers, increases science literacy, and enables the next generation of innovators, which leads to new products and processes that sustain our economy (Hossain & Robinson, 2012). We have been hearing the warnings for several years, that there simply are not enough young scientists entering into the STEM professional pathways to replace all of the retiring professionals (Brown, Brown, Reardon, & Merrill, 2011; Harsh, Maltese, & Tai, 2012; Heilbronner, 2011; Scott, 2012). The problem is not necessarily due to a lack of STEM skills and concept proficiency. There also appears to be a lack of interest in these fields. Recent evidence suggests that many of the most proficient students, especially minority students and women, have been gravitating away from science and engineering toward other professions. (President's Council of Advisors on Science and Technology, 2010). The purpose of this qualitative research study was an attempt to determine how high schools can best prepare and encourage young women for a career in engineering or computer science. This was accomplished by interviewing a pool of 21 women, 5 recent high school graduates planning to major in STEM, 5 college students who had completed at least one full year of coursework in an engineering or computer science major and 11 professional women who had been employed as an engineer or computer scientist for at least one full year. These women were asked to share the high school courses, activities, and experiences that best prepared them to pursue an engineering or computer science major. Five central themes emerged from this study; coursework in physics and calculus, promotion of STEM camps and clubs, teacher encouragement of STEM capabilities and careers, problem solving, critical thinking and confidence building activities in the classroom, and allowing students the opportunity to fail and ask questions in a safe environment. These

    In response to the publication of Vision and Change, the biology department at Elmhurst College revised our curriculum to better prepare students for a career in science with the addition of various writing assignments in every course. One commonality among all of the assignments is the ability to comprehend and critically evaluate scientific literature to determine relevancy and possible future research. Several previous reports have analyzed specific methodologies to improve student comprehension of scientific writing and critical thinking skills, yet none of these examined student growth over an undergraduate career. In this study, we hypothesized upper-level students would be better able to comprehend and critically analyze scientific literature than introductory biology majors. Biology students enrolled in an introductory (200-level), mid- (300-level), or late-career (400-level) course were tasked with reading and responding to questions regarding a common scientific article and rating their comfort and confidence in reading published literature. As predicted, upper-level (mid- and late-career) students showed increases in comprehension and critical analysis relative to their first-year peers. Interestingly, we observed that upper-level students read articles differently than introductory students, leading to significant gains in understanding and confidence. However, the observed gains were modest overall, indicating that further pedagogical change is necessary to improve student skills and confidence in reading scientific articles while fulfilling the Vision and Change recommendations.

    2015-12-01

    NASA's Science Mission Directorate (SMD) recognizes that suborbital carriers play a vital role in training our country's future science and technology leaders. SMD created the Undergraduate Student Instrument Project (USIP) to offer students the opportunity to design, build, and fly instruments on NASA's unique suborbital research platforms. This paper explores the projects, the impact, and the lessons learned of USIP. USIP required undergraduate teams to design, build, and fly a scientific instrument in 18 months or less. Students were required to form collaborative multidisciplinary teams to design, develop and build their instrument. Teams quickly learned that success required skills often overlooked in an academic environment. Teams quickly learned to share technical information in a clear and concise manner that could be understood by other disciplines. The aggressive schedule required team members to hold each other accountable for progress while maintaining team unity. Unanticipated problems and technical issues led students to a deeper understanding of the need for schedule and cost reserves. Students exited the program with a far deeper understanding of project management and team dynamics. Through the process of designing and building an instrument that will enable new research transforms students from textbook learners to developers of new knowledge. The initial USIP project funded 10 undergraduate teams that flew a broad range of scientific instruments on scientific balloons, sounding rockets, commercial rockets and aircraft. Students were required to prepare for and conduct the major reviews that are an integral part of systems development. Each project conducted a Preliminary Design Review, Critical Design Review and Mission Readiness review for NASA officials and flight platform providers. By preparing and presenting their designs to technical experts, the students developed a deeper understanding of the technical and programmatic project pieces that

  7. Leadership's Role in Recruitment and Retention of First Generation, Low-Income Latino Students into STEM Majors

    Gonzalez, Eliseo A.

    Fostering resiliency and educational success in students that are faced with adversity is not a simple task. The gap in educational success and achievement among low-income, first generation, traditionally marginalized students continues to be significant. California's educational system needs to stop the hemorrhaging from its educational pipeline, also known as the P-20 pipeline, of all students, especially those groups of students with larger gaps in educational attainment. One potential path towards fixing California's educational pipeline for all students is to form and keep partnerships with programs such as Upward Bound, AVID, and Math Engineering Science Achievement (MESA). In 2010-11, the California Department of Education (CDE) reported that over 51% of students enrolled in California's school system and 51% of all California high school seniors were Latino were Latino. Of the 231,231 Latino high school seniors, 79%, graduated. However, of those that graduated, only 26%, met University of California/California State University (UC/CSU) college entrance requirements. Even though 79% of Latinos graduated, 74% did not qualify to apply to a UC or CSU. If the majority of Latino students continue to fall through holes in the educational pipeline, companies will continue to look abroad to fill STEM jobs that remain unfilled by American workers (California Department of Education [CDE], 2012). Alongside the U.S.'s current economic woes, the lack of college preparedness and knowledge by parents and students has led to a decrease in first generation, low-income Latino students' higher education enrollment (Camacho & Lord, 2011). With strong and positive leadership from family, supplemented by the MESA program, these youths can exert their resiliency, face adversity, and overcome extraordinary barriers. Leaders in education such as teachers, coordinators, advisers, administrators, and parents are in the best position to teach students about resilience (Ginsburg, 2007

    Using the Educational Longitudinal Study of 2002/06, this study examined the effects of the selected mathematical learning and teacher motivation factors on graduates' science, technology, engineering, and math (STEM) related major choices in 4-year colleges and universities, as mediated by math performance and math self-efficacy. Using multilevel structural equation modeling, I analyzed: (1) the association between mathematical learning instruction factors (i.e., computer, individual, and lecture-based learning activities in mathematics) and students' STEM major choices in 4-year colleges and universities as mediated by math performance and math self-efficacy and (2) the association between school factor, teacher motivation and students' STEM major choices in 4-year colleges and universities via mediators of math performance and math self-efficacy. The results revealed that among the selected learning experience factors, computer-based learning activities in math classrooms yielded the most positive effects on math self-efficacy, which significantly predicted the increase in the proportion of students' STEM major choice as mediated by math self-efficacy. Further, when controlling for base-year math Item Response Theory (IRT) scores, a positive relationship between individual-based learning activities in math classrooms and the first follow-up math IRT scores emerged, which related to the high proportion of students' STEM major choices. The results also indicated that individual and lecture-based learning activities in math yielded positive effects on math self-efficacy, which related to STEM major choice. Concerning between-school levels, teacher motivation yielded positive effects on the first follow up math IRT score, when controlling for base year IRT score. The results from this study inform educators, parents, and policy makers on how mathematics instruction can improve student math performance and encourage more students to prepare for STEM careers.

    Sulaiman, Munir

    Science, technology, engineering, and mathematics (STEM) programs in higher education institutions, particularly engineering programs, face challenges related to recruitment, retention, and graduation rates. The purpose of this study was to determine whether there are significant relationships among students' major preference, academic skills, nonacademic characteristics and perceptions, and retention to year 2 among students in electronic engineering, other STEM, and non STEM majors. The academic skills considered were study habits, intellectual interest, verbal and writing confidence, and academic assistance. The non-academic factors included academic support, family support, financial support, and student social integration into the campus environment. Tinto's theory of retention served as the theoretical framework. The research design was quantitative with a general linear method of analysis using responses to the College Student Inventory (CSI) survey as secondary data to determine the relationships among the independent variables (major and academic and non-academic factors) and dependent variable (retention). Participants were 3,575 first year undergraduate full-time students from three entering classes, 2012 to 2014. Findings suggested that student major and non-academic factors had no effect on student retention, but student study habits and seeking academic assistance were predictors of retention in each of the three groups of majors: engineering, other STEM majors, and nonSTEM majors. Strategies to help increase undergraduate students' study skills and help seeking behaviors may contribute to positive social change at HBCU institutions.

    Full Text Available Stem canker and black scurf diseases of potatoes are caused by the basidiomycetous fungus Thanatephorus cucumeris (anamorphic species complex Rhizoctonia solani. These diseases have worldwide distribution wherever potato is grown but their etiology varies depending on the predominance of distinct R. solani anastomosis groups (AG s in a particular area. Within the species complex, several AG s have been associated with stem canker or black scurf diseases, including AG -1, AG -2-1, AG -2-2, AG -3, AG -4, AG -5 and AG -9. This article reports on the most comprehensive population-based study, providing evidence on the distribution of R. solani AG s in Colombian potato fields. A total of 433 isolates were sampled from the main potato cropping areas in Colombia from 2005 to 2009. Isolates were assigned to AG s by conventional PCR assays using specific primers for AG -3, sequencing of the ITS -rDNA and hyphal interactions. Most of the isolates evaluated were assigned to AG -3PT (88.45%, and a few to AG -2-1 (2.54%. The remaining isolates were binucleate Rhizoctonia (AG -A, E, and I. Pathogenicity tests on the stems and roots of different plant species, including the potato, showed that AG -3PT affects the stems of solanaceous plants. In other plant species, damage was severe in the roots, but not the stems. AG -2-1 caused stem canker of Solanum tuberosum cv. Capiro and in R. raphanistrumi and B.campestris subsp. Rapa plantlets and root rot in other plants. The results of our study indicated that R. solani AG -3PT was the principal pathogen associated with potato stem canker and black scurf diseases of potatoes in Colombia

    Simpson, Amber; Maltese, Adam

    2017-04-01

    The term failure typically evokes negative connotations in educational settings and is likely to be accompanied by negative emotional states, low sense of confidence, and lack of persistence. These negative emotional and behavioral states may factor into an individual not pursuing a degree or career in science, technology, engineering, or mathematics (STEM). This is of particular concern considering the low number of women and underrepresented minorities pursing and working in a STEM field. Utilizing interview data with professionals across STEM, we sought to understand the role failure played in the persistence of individuals who enter and pursue paths toward STEM-related careers. Findings highlighted how participants' experiences with failure (1) shaped their outlooks or views of failure, (2) shaped their trajectories within STEM, and (3) provided them with additional skills or qualities. A few differences based on participants' sex, field, and highest degree also manifested in our analysis. We expect the results from this study to add research-based results to the current conversation around whether experiences with failure should be part of formal and informal educational settings and standards-based practices.

    Heilbronner, Nancy N.

    Many men and women who are talented in science, technology, engineering, and/or mathematics (STEM) choose not to pursue undergraduate majors or careers in these fields. To develop talents in STEM, educators must understand the factors that contribute to an individual's retention in STEM domains, as well as the factors that act as barriers to success, such as the role that gender plays in the underrepresentation of women in certain STEM fields (e.g., computer science and engineering) and changes in recent decades in the process of selecting STEM majors and careers. The purpose of this study was to explore the influences that guide decisions related to the selection of majors and occupations during high school, post-secondary education, and early careers. Survey methodology was used to explore the perceptions of 360 Science Talent Search (STS) semifinalists and finalists during the years 1987-1989 and 1997-1999, and quantitative procedures were used to analyze the data. A majority (74.2%) of STS participants majored in a STEM field in college, and most (68.6%) currently work in a STEM field. A greater percentage of men selected computer science, engineering, physics, and mathematics majors, and a greater percentage of women selected biological science and chemistry. Belief in one's ability to achieve in STEM was a predictor of STEM majors in college and STEM concentrations in graduate school, but differences were found between men's and women's self-efficacy in STEM during high school and in college, as women had lower self-efficacy. Sex was a predictor of STEM majors in college, but perceived quality of academic courses was not. STEM majors also reported more satisfaction with their STEM courses in high school and college than non-STEM majors. In a departure from the results of previous research, the reasons that men and women selected occupations were similar, as were the reasons they chose to leave or not to enter STEM. The most frequently cited reason for

    Little, David L., II

    Ongoing changes in values, pedagogy, and curriculum concerning sustainability education necessitate that strong curricular elements are identified in sustainability education. However, quantitative research in sustainability education is largely undeveloped or relies on outdated instruments. In part, this is because no widespread quantitative instrument for measuring related educational outcomes has been developed for the field, though their development is pivotal for future efforts in sustainability education related to STEM majors. This research study details the creation, evaluation, and validation of an instrument -- the STEM Sustainability Engagement Instrument (STEMSEI) -- designed to measure sustainability engagement in post-secondary STEM majors. The study was conducted in three phases, using qualitative methods in phase 1, a concurrent mixed methods design in phase 2, and a sequential mixed methods design in phase 3. The STEMSEI was able to successfully predict statistically significant differences in the sample (n= 1017) that were predicted by prior research in environmental education. The STEMSEI also revealed statistically significant differences between STEM majors' sustainability engagement with a large effect size (.203 ≤ eta2 ≤ .211). As hypothesized, statistically significant differences were found on the environmental scales across gender and present religion. With respect to gender, self-perceived measures of emotional engagement with environmental sustainability was higher with females while males had higher measures in cognitive engagement with respect to knowing information related to environmental sustainability. With respect to present religion, self-perceived measures of general engagement and emotional engagement in environmental sustainability were higher for non-Christians as compared to Christians. On the economic scales, statistically significant differences were found across gender. Specifically, measures of males' self

    Espinosa, Lorelle L.

    If we are to respond to the call for equity in the representation of minority men and women in science, technology, engineering, and math (STEM) disciplines, we must be concerned with those college experiences that impact students' sense of self. This study addresses the 4-year development of academic self-concept for African American and Latina(o) students graduating with STEM degrees, with an emphasis placed on gender differences. Ordinary Least Squares regression was utilized to explore predictors of academic self-concept for male and female students. Findings emphasize the paramount role of the college environment as compared to background and precollege characteristics. Significant predictors exclusive to women include having positive academic self-expectations and valuing group work in a classroom setting. Significant predictors for men include being given the opportunity to work on a professor's research project and finding satisfaction with science and math coursework.

    Full Text Available Bone marrow transplantation (BMT is the only possible curative treatment for β-thalassemia major. The largest experience occurred in Pesaro, Italy, where the BMT was applied after a standard risk assessment. The patients were divided into 3 risk classes based on liver size by physical examination, the presence or absence of fibrosis by liver biopsy, and adherence to regular iron chelation. Outcomes were mainly affected by the risk status. After modifications to the conditioning regimens, the risk of transplantation-related complications in highrisk recipients reduced considerably. As a result, outcomes after transplantation have become more similar across risk categories. For BMT, most centers use bone marrow instead of peripheral blood in thalassemia. Some studies showed that peripheral blood stem cell transplantation (PBSCT is better than BMT with regard to hematologic recovery, hospitalization period, leukemia-free survival, overall survival (OS, and transplant-related mortality (TRM. No significant differences were seen in grade II to IV acute GVHD (aGVHD; but the incidence of chronic GVHD (cGVHD was significantly higher in the PBSCT group. BMT from unrelated donors may offer similar results to those obtained using HLA-identical family donors, at least for patients who are not fully compliant with conventional treatment and do not yet show severe complications of iron overload. All studies conclude that MUD BMT might be a good alternative for patients with less risk factors. Another study concluded that, at present, due to high graft failure and GVHD rates, BMT from alternative donors should be restricted to patients who have poor life expectancies because they cannot receive adequate conventional treatment or because of alloimmunization to minor blood antigens. In another study unrelated cord blood transplantation (CBT was compared to related donor transplantation for children with β-thalassemia. The results were comparable to the

Short-term, intensive programs provide opportunities to participate in authentic scientific research for students who may not be sure of their interest in science and for teachers who may be unable to devote an entire summer to a research experience. The iUTAH (innovative Urban Transitions and Aridregion Hydro-Systainability) Summer Research Institute utilizes an innovative approach for a 5-day program that engages high school and undergraduate students as well as middle and high school teachers in conducting research projects led by graduate students and faculty members. Each Institute involves 3-4 half to full-day research projects. Participants collect (usually in the field) and analyze data for use in on-going research or that is related to a current research project. The participants work in groups with the graduate students to create a poster about each research project. They present their posters on the last day of the Institute at the state-wide meeting of all researchers and involved in this EPSCoR-funded program. In addition to introducing participants to research, one of the Institute's goals is to provide opportunities for meaningful near-peer interactions with students along the STEM pipeline from high school to undergraduate to graduate school. On the end-of-Institute evaluations, almost all students have reported that their discussions with other participants and with graduate students and faculty were a "Highly effective" or "Effective" part of the Institute. In response to a question about how the Institute will impact their course choices or their plans to pursue a career in science, many high school and undergraduate students have noted that they plan to take more science courses. Each year several undergraduates who were previously unsure about a career in science have indicated that they now intend to pursue a

  2. Rethinking the STEM fields: The importance of definitions in examining women's participation and success in the sciences

    Science.gov (United States)

    George-Jackson, Casey Elizabeth

    This study uses longitudinal data of undergraduate students from five public land-grant universities to better understand undergraduate students' persistence in and switching of majors, with particular attention given to women's participation in Science, Technology, Engineering, and Mathematics (STEM) fields. Specifically, the study examines patterns of behavior of women and minorities in relation to initial choice of college major and major field persistence, as well as what majors students switched to upon changing majors. Factors that impact major field persistence are also examined, as well as how switching majors affects students' time-to-degree. Using a broad definition of STEM, data from nearly 17,000 undergraduate students was analyzed with descriptive statistics, cross tabulations, and binary logistic regressions. The results highlight women's high levels of participation and success in the sciences, challenging common notions of underrepresentation in the STEM fields. The study calls for researchers to use a comprehensive definition of STEM and broad measurements of persistence when investigating students' participation in the STEM fields.

    2012-12-01

    This article investigates the empirical basis for often-repeated arguments that gender differences in entrance into STEM majors are largely explained by disparities in prior achievement. Analyses use data from three national cohorts of college matriculates across three decades to consider differences across several indicators of high school math and science achievement at the mean and also at the top of the test distribution. Analyses also examine the different comparative advantages men and women enjoy in math/science vs. English/reading. Regardless of how prior achievement is measured, very little of the strong and persistent gender gap in physical science and engineering majors over time is explained. Findings highlight the limitations of theories focusing on gender differences in skills and suggest directions for future research.

  5. Why (and how) they decide to leave: A grounded theory analysis of STEM attrition at a large public research university

    Science.gov (United States)

    Minutello, Michael F.

    A grounded theory investigation of STEM attrition was conducted that describes and explains why undergraduates at a large Mid-Atlantic research university decided to leave their initial STEM majors to pursue non-STEM courses of study. Participants ultimately decided to leave their initial STEM majors because they were able to locate preferable non-STEM courses of study that did not present the same kinds of obstacles they had encountered in their original STEM majors. Grounded theory data analysis revealed participants initially enrolled in STEM majors with tenuous motivation that did not withstand the various obstacles that were present in introductory STEM coursework. Obstacles that acted as demotivating influences and prompted participants to locate alternative academic pathways include the following: (1.) disengaging curricula; (2.) competitive culture; (3.) disappointing grades; (4.) demanding time commitments; and (5.) unappealing career options. Once discouraged from continuing along their initial STEM pathways, participants then employed various strategies to discover suitable non-STEM majors that would allow them to realize their intrinsic interests and extrinsic goals. Participants were largely satisfied with their decisions to leave STEM and have achieved measures of personal satisfaction and professional success.

  6. A Seminar Course to Prepare Astronomy Undergraduate Students for Multiple Career Paths

    Hayes-Gehrke, Melissa; Harris, Andrew

    2018-01-01

    The increasing focus on the importance of STEM careers has led increasing numbers of students to enroll in STEM majors at the University of Maryland, including traditionally smaller majors such as Astronomy. The pursuit of a PhD is neither desirable nor appropriate for many of these students, but most of them lack knowledge of other options open to students with a rigorous science undergraduate degree. We have developed an interactive seminar (1-credit) course (first offered in Fall 2017) intended to expose new Astronomy majors to an array of possible career paths, and give them guidance on steps they can take to prepare for these careers as well as graduate school. Supporting topics include discussions of the elements necessary for success in their undergraduate studies, skills needed preparing for undergraduate research and internship experiences, and showing them how and when an undergraduate research experience will be beneficial for them. We present the seminar course learning goals, topic list and course structure, and results of pre- and post-attitudes surveys.

  7. Experiences of Judeo-Christian Students in Undergraduate Biology

    2017-01-01

    A major research thrust in science, technology, engineering, and mathematics (STEM) education is focused on how to retain students as STEM majors. The accumulation of seemingly insignificant negative experiences in STEM classes can, over time, lead STEM students to have a low sense of belonging in their disciplines, and this can lead to lower retention. In this paper, we explore how Judeo-Christian students in biology have experiences related to their religious identities that could impact their retention in biology. In 28 interviews with Judeo-Christian students taking undergraduate biology classes, students reported a religious identity that can conflict with the secular culture and content of biology. Some students felt that, because they are religious, they fall within a minority in their classes and would not be seen as credible within the biology community. Students reported adverse experiences when instructors had negative dispositions toward religion and when instructors were rigid in their instructional practices when teaching evolution. These data suggest that this may be a population susceptible to experiences of cultural conflict between their religious identities and their STEM identities, which could have implications for retention. We argue that more research should explore how Judeo-Christian students’ experiences in biology classes influence their sense of belonging and retention. PMID:28232586

    The Pre-Major in Astronomy Program (Pre-MAP) is a research and mentoring program for underclassmen and transfer students offered by the University of Washington Astronomy Department since 2005. The primary goal of Pre-MAP is to recruit and retain students from groups traditionally underrepresented in science, technology, engineering, and mathematics (STEM) through early exposure to research. The Pre-MAP seminar is the core component of the program and offers instruction in computing skills, data manipulation, science writing, statistical analysis, and scientific speaking and presentation skills. Students choose research projects proposed by faculty, post-docs and graduate students in areas related to astrophysics, planetary science, and astrobiology. Pre-MAP has been successful in retaining underrepresented students in STEM fields relative to the broader UW population, and we've found these students are more likely to graduate and excel academically than their peers. As of spring 2015, more than one hundred students have taken the Pre-MAP seminar, and both internal and external evaluations have shown that all groups of participating students report an increased interest in astronomy and science careers at the end of the seminar. Several former Pre-MAP students have obtained or are pursuing doctoral and master’s degrees in STEM fields; many more work at NASA centers, teaching colleges, or as engineers or data analysts. Pre- MAP student research has produced dozens of publications in peer-reviewed research journals. This talk will provide an overview of the program: the structure of the seminar, examples of projects completed by students, cohort-building activities outside the seminar, funding sources, recruitment strategies, and the aggregate demographic and achievement data of our students. It is our hope that similar programs may be adopted successfully at other institutions.

    Professor Bard has provided a valuable service by carefully explaining everything an undergraduate student of mathematics, or a teacher of these topics, needs to get started with Sage quickly and easily. It will also be useful for any student or teacher of another STEM discipline. There is an excellent mix of the most frequently used commands, along with warnings about common pitfalls or caveats. I highly recommend it for anyone new to Sage, or who desires an overview of the system's impressive capabilities. -Robert A. Beezer, University of Puget Sound This book is a sort of "Missing Manual"

    Within the past decade, course-based undergraduate research experiences (CUREs) have emerged as a viable mechanism to enhance novices’ development of scientific reasoning and process skills in the science, technology, engineering, and mathematics disciplines. Recent evidence within the bioeducation literature suggests that student engagement in such experiences not only increases their appreciation for and interest in scientific research but also enhances their ability to “think like a scientist.” Despite these critical outcomes, few studies have objectively explored CURE versus non-CURE students’ development of content knowledge, attitudes, and motivation in the discipline, particularly among nonvolunteer samples. To address these concerns, we adopted a mixed-methods approach to evaluate the aforementioned outcomes following implementation of a novel CURE in an introductory cell/molecular biology course. Results indicate that CURE participants exhibited more expert-like outcomes on these constructs relative to their non-CURE counterparts, including in those areas related to self-efficacy, self-determination, and problem-solving strategies. Furthermore, analysis of end-of-term survey data suggests that select features of the CURE, such as increased student autonomy and collaboration, mediate student learning and enjoyment. Collectively, this research provides novel insights into the benefits achieved as a result of CURE participation and can be used to guide future development and evaluation of authentic research opportunities.

  15. CD90(+) stromal cells are the major source of IL-6, which supports cancer stem-like cells and inflammation in colorectal cancer.

    IL-6 is a pleiotropic cytokine increased in CRC and known to directly promote tumor growth. Colonic myofibroblasts/fibroblasts (CMFs or stromal cells) are CD90(+) innate immune cells representing up to 30% of normal colonic mucosal lamina propria cells. They are expanded in CRC tumor stroma, where they also known as a cancer associated fibroblasts (CAFs). Cells of mesenchymal origin, such as normal myofibroblasts/fibroblasts, are known to secrete IL-6; however, their contribution to the increase in IL-6 in CRC and to tumor-promoting inflammation is not well defined. Using in situ, ex vivo and coculture analyses we have demonstrated that the number of IL-6 producing CMFs is increased in CRC (C-CMFs) and they represent the major source of IL-6 in T2-T3 CRC tumors. Activity/expression of stem cell markers-aldehyde dehydrogenase and LGR5- was significantly up-regulated in colon cancer cells (SW480, Caco-2 or HT29) cultured in the presence of conditioned medium from tumor isolated C-CMFs in an IL-6 dependent manner. C-CMF and its derived condition medium, but not normal CMF isolated from syngeneic normal colons, induced differentiation of tumor promoting inflammatory T helper 17 cells (Th17) cell responses in an IL-6 dependent manner. Our study suggests that CD90(+) fibroblasts/myofibroblasts may be the major source of IL-6 in T2-T3 CRC tumors, which supports the stemness of tumor cells and induces an immune adaptive inflammatory response (a.k.a. Th17) favoring tumor growth. Taken together our data supports the notion that IL-6 producing CAFs (a.k.a. C-CMFs) may provide a useful target for treating or preventing CRCs. © 2015 UICC.

    2017-06-01

    Students enrolled in introductory astronomy at a mid-sized land grant institution were surveyed at the start and end of each semester for three years regarding their epistemic beliefs about the physical sciences. After collecting data for two years in the control (baseline) course, the course was revised to include regular discussions of the nature of science, practice identifying pseudoscientific claims, and practice with metacognition. Survey data on epistemic beliefs were collected for one more academic year after the course was revised. This work details how the course was structured during the baseline and revised portions of the study. Data from both portions of the study are analyzed as a whole as well as broken down by gender. Negative trends seen in the baseline data are mostly eradicated in the revised portion of the course. The data analysis motivates a discussion of why including content regarding the nature of science should be integrated in classes geared toward non-science majors.

  17. Two major gate-keepers in the self-renewal of neural stem cells: Erk1/2 and PLCγ1 in FGFR signaling

    Directory of Open Access Journals (Sweden)

    Lee Jin-A

    2009-06-01

    Full Text Available Abstract Neural stem cells are undifferentiated precursor cells that proliferate, self-renew, and give rise to neuronal and glial lineages. Understanding the molecular mechanisms underlying their self-renewal is an important aspect in neural stem cell biology. The regulation mechanisms governing self-renewal of neural stem cells and the signaling pathways responsible for the proliferation and maintenance of adult stem cells remain largely unknown. In this issue of Molecular Brain [Ma DK et al. Molecular genetic analysis of FGFR1 signaling reveals distinct roles of MAPK and PLCγ1 activation for self-renewal of adult neural stem cells. Molecular Brain 2009, 2:16], characterized the different roles of MAPK and PLCγ1 in FGFR1 signaling in the self-renewal of neural stem cells. These novel findings provide insights into basic neural stem cell biology and clinical applications of potential stem-cell-based therapy.

  18. Cultivating Citizen Scientists in the Undergraduate Science Classroom

    Science.gov (United States)

    Egger, A. E.

    2007-12-01

    Several studies indicate a strong correlation between the number of college science courses and science literacy. It is not surprising, then, that the majority of participants in citizen science projects are college graduates who enrolled in at least two science courses. If one goal of citizen science projects is to increase civic science literacy, research suggests that most are preaching to the choir. Attracting a wider audience to citizen science is, therefore, a key challenge. One way to address this challenge is to attract students to enroll and succeed in science courses in college, even if they do not pursue a major in the science, technology, engineering, and mathematics (STEM) disciplines. In fact, only 20% of students receive a degree in STEM, yet virtually all undergraduates are required to take at least one science course. Introductory science courses are therefore critical to cultivating citizen scientists, as they include a large proportion of non- STEM majors. Indeed, a major thrust of recent undergraduate STEM educational reform has been the promotion of 'science for all'. The science for all concept goes beyond recruiting students into the STEM disciplines to promoting a level of scientific literacy necessary to make informed decisions. A clear implication of this inclusive attitude is the need to redesign introductory science courses to make them accessible and explicitly related to scientific literacy. This does not mean dumbing down courses; on the contrary, it means engaging students in real scientific investigations and incorporating explicit teaching about the process of science, thus fostering a lifelong appreciation for (and, hopefully, participation in) science. Unfortunately, many students enter college with minimal understanding of the process of science. And when they arrive in their introductory classes, science is presented to them as a system of facts to be memorized - comparable to memorizing a poem in a foreign language without

    REU (research experience for undergraduate) programs in science serve as a centerpiece for: recruitment improved learning, retention and increased graduation rates among students in STEM fields. Structured REUs are highly effective programs for broadening participation and remedying inequities, to increase and diversify the STEM talent pool and professional workforce. Now in its 16th year, SOARS is dedicated to broadening participation in the atmospheric and related sciences. SOARS is an undergraduate through graduate program built on the structure of: a summer research internship, mentoring by professional scientists, and a supportive learning community. SOARS is an exemplar. Its structure serves as a paradigm case for the recruitment, retention, and graduation of students from underserved populations. This research-based examination of SOARS explores its program elements and identifies attributes and practices that contribute to its impact and lasting outcomes.

  20. Effect of Out-of-School Time STEM Education Programs: Implications for Policy

    Science.gov (United States)

    Talbot, Harry A.

    Today's world requires greater STEM knowledge for employment and understanding of emerging issues. A predicted 3 million jobs will be created in STEM-related fields but the percentage of earned STEM-related degrees is diminishing. A lack of progress in STEM education for American students is most pronounced among females who make up 48% of the workforce and 24% of STEM employees. A lack of STEM interest among students is compounded by limited time in the school day for STEM topics, lack of teacher confidence in teaching STEM, and a lack of professional development. This study examines the impact of Out-of-School-Time (OST) programs on knowledge acquisition and attitudes toward STEM topics by gender. Program content was delivered by undergraduate pre-teacher candidates and undergraduate STEM majors, using a structured, hands-on engineering program developed for the National Aeronautics and Space Administration (NASA). Monthly professional development was provided to OST staff by NASA content specialists and instructors from Fresno State University. A repeated-measures design analyzed group differences across three points in time: prior to the start of instruction (pretest), immediately following the end of instruction (posttest), and 60 days following (post posttest). A within-group comparison measured posttest and post-post-test changes for each gender. Program students included in the study participated for at least 12 of the 24 program hours offered and completed all three assessments. The findings showed that STEM knowledge acquisition advanced at similar levels for both genders. These results were consistent with the existing research. Findings related to attitudes toward STEM topics showed that female students did not change over time but males students' interest lessened over time. These findings did not support the current research in this area. Recommendations for practice include developing programs that focus on gender differentiated learning styles

    2011-12-01

    The University of Michigan offers a 100-level course entitled, "Our Changing Atmosphere," often taken to fulfill the natural science distribution credit requirement by up to 200 students in non-technical majors per term. This course covers the properties and structure of the atmosphere and how they are changing, emphasizing the global climate and climate change. After a brief introduction to atmospheric basics, highlights from Earth's climate history are presented, followed by modern-day changes to climate, such as air pollution, stratospheric ozone depletion, and global warming. The current format of the course relies heavily on Lecturebook, Lecturetools, and C-tools as online electronic resources for the class. The textbook for the course is managed through Lecturebook, which also provides hyperlinked text and hundreds of built-in questions for homework sets and student review. The recitation lessons are uploaded to Lecturebook, which allows for interactive question-and-answer sessions during class in multiple formats. The University of Michigan's C-tools environment is also used for email distribution and archiving, additional resource postings, and as a backup to these other two websites. The structure of the class permits different instructors to emphasize different facets of climate, and to employ different instructional techniques. For example, the textbook differs depending on the term the course is offered. One of us emphasizes good-vs-bad science usage via video, sound clip, or PDF posting on a weather or climate related topic in every lecture. Good-v-bad science usage of climate topics in research, media reporting, and casual conversation are all discussed by the students and included in the examinations. The other instructor emphasizes the findings of the IPCC, employs hands-on activities in lecture and eschews exams in favor of collaborative homework assignments. The assignments include qualitative and quantitative analyses of climate topics and the

    Improving science, technology, engineering, and mathematics (STEM) education, especially for traditionally disadvantaged groups, is widely recognized as pivotal to the U.S.’s long-term economic growth and security. In this article, we review and discuss current research on STEM education in the U.S., drawing on recent research in sociology and related fields. The reviewed literature shows that different social factors affect the two major components of STEM education attainment: (1) attainment of education in general, and (2) attainment of STEM education relative to non-STEM education conditional on educational attainment. Cognitive and social psychological characteristics matter for both major components, as do structural influences at the neighborhood, school, and broader cultural levels. However, while commonly used measures of socioeconomic status (SES) predict the attainment of general education, social psychological factors are more important influences on participation and achievement in STEM versus non-STEM education. Domestically, disparities by family SES, race, and gender persist in STEM education. Internationally, American students lag behind those in some countries with less economic resources. Explanations for group disparities within the U.S. and the mediocre international ranking of US student performance require more research, a task that is best accomplished through interdisciplinary approaches.

  3. The effect of graphic organizers on students' attitudes and academic performance in undergraduate general biology

    Science.gov (United States)

    Cleveland, Lacy

    High attrition among undergraduate Science Technology Engineering and Mathematics (STEM) majors has led national and business leaders in the United States to call for both research and educational reform within the collegiate STEM classrooms. Included among suggestions for reform are ideas to improve retention of first-year students and to improve critical thinking and depth of knowledge, instead of covering large quantities of materials. Past research on graphic organizers suggest these tools assist students in learning information and facilitate conceptual and critical thinking. Despite their widespread use in high school science departments, collegiate humanities departments, and even medical schools, their use is considerably less prevalent in the undergraduate biology classroom. In addition to their lack of use, little research has been conducted on their academic benefits in the collegiate classroom. Based on national calls for improving retention among undergraduate STEM majors and research suggesting that academic success during an individual first major's related course highly determine if that individual will continue on in their intended major, the researcher of this dissertation chose to conduct research on an introductory general biology class. Using both quantitative and qualitative methods, the research in this dissertation examines the effectiveness of graphic organizers in promoting academic success and also examines their influence on student attitudes. This research is grounded in the theories of constructivism and cognitive load theory. Constructivism suggests that individuals must build their knowledge from their personal experiences, while the cognitive load theory recognizes the limited nature of one's working memory and suggests that instructional practices minimize cognitive overload. The results of this dissertation suggest that the use of graphic organizers in an undergraduate general biology classroom can increase students' academic

  4. Untypical Undergraduate Research: Player Motion Analysis in Sports

    Loerke, Dinah

    There is significant concern about the degree of attrition in STEM disciplines from the start of K-12 through to the end of higher education, and the analysis of the `leaky pipeline' from the various institutions has identified a critical decline - which may be as high as 60 percent - between the fraction of students who identify as having an interest in a science or engineering major at the start of college/university, and the fraction of students who ultimately graduate with a STEM degree. It has been shown that this decline is even more dramatic for women and underrepresented minorities (Blickenstaff 2005, Metcalf 2010). One intervention which has been proven to be effective for retention of potential STEM students is early research experience, particularly if it facilitates the students' integration into a STEM learning community (Graham et al. 2013, Toven-Lindsey et al. 2015). In other words, to retain students in STEM majors, we would like to encourage them to `think of themselves as scientists', and simultaneously promote supportive peer networks. The University of Denver (DU) already has a strong undergraduate research program. However, while the current program provides valuable training for many students, it likely comes too late to be effective for student retention in STEM, because it primarily serves older students who have already finished the basic coursework in their discipline; within physics, we know that the introductory physics courses already serve as gatekeeper courses that cause many gifted but `non-typical' students to lose interest in pursuing a STEM major (Tobias 1990). To address this issue, my lab is developing a small research spinoff program in which we apply spatiotemporal motion analysis to the motion trajectories of players in sports, using video recordings of DU Pioneer hockey games. This project aims to fulfill a dual purpose: The research is framed in a way that we think is attractive and accessible for beginning students who

    In red winemaking de-stemming is crucial since the stems contain polymeric phenolic compounds responsible for the astringency of wine. Wine such as Primitivo has low phenolic constituents and tannins and stems affect aroma, taste body and olfactory characteristics. The aim of the study was to evaluate the effects of presence of stems during fermentation on polyphenolic, volatile compounds and sensory characteristics of wine. Primitivo grapes vinified in presence of different percentage of stems: 100 % de-stemmed (D100), 75 % de-stemmed (D75) and 50 % de-stemmed (D50). Results confirmed that the wines vinified in presence of stems were higher in tannins, flavans, to vanillin and proanthocyanidins, colour intensity with lower anthocyanins. The presence of stems during fermentation conferred more structure and flavour to wines. They facilitated must aeration thus promoting synthesis of higher alcohols and ethyl esters by yeast. In particular, a higher content of hexan-1-ol, hex-3-en-1-ol and 2-phenyl ethanol in D50 and D75 gave the wines that suggest green grass, herb and floral. Wine from D75 seemed to be better than D50 in terms of volatile compounds as well as fruity, floral and balsamic components preserved, without any unpleasant taste of long chain fatty acids found in D50.

    Collegiate-level musical theater performance students are a specialized group of vocal performers, who rely on frequent and optimal voice use for their academic advancement and ultimate livelihood. The purpose of this study was to gather information to develop a greater understanding of vocal health and practice patterns of incoming collegiate-level musical theater performers. Data obtained from questionnaires completed by freshman musical theater majors were retrospectively analyzed to gather information about baseline vocal habits of the participants. Results of a questionnaire were obtained from incoming freshman musical theater students at the Cincinnati Conservatory of Music over a period of 10 years (2002-2011). One hundred eighty-eight participants (female = 90) (male = 98) with an average age of 18.28 years (standard deviation = 0.726) were included. Results specifying participants' self-reported vocal training and practice habits, vocal health and hygiene practices, and current vocal symptoms or contributing factors to potential voice problems are provided. Data obtained from the participants revealed that the potential for vocal problems exists in this group of performers, as over half of the subjects reported at least one current negative vocal symptom. The findings from this study provide information that may be useful for individuals who are involved in the training of vocal performers. Copyright © 2014 The Voice Foundation.

    Full Text Available Abstract Background The relationship between functional improvements in ischemic rats given a neural stem cell (NSC transplant and the modulation of the class I major histocompatibility complex (MHC mediated by NSC-derived neurotrophins was investigated. Methods The levels of gene expression of nerve growth factor (NGF, brain-derived neurotropic factor (BDNF and neurotrophin-3 (NT-3 were assayed from cultures of cortical NSC from Sprague-Dawley rat E16 embryos. The levels of translated NGF in spent culture media from NSC cultures and the cerebral spinal fluid (CSF of rats with and without NGF injection or NSC transplant were also measured. Results We found a significant increase of NGF, BDNF and NT-3 transcripts and NGF proteins in both the NSC cultures and the CSF of the rats. The immunochemical staining for MHC in brain sections and the enzyme-linked immunosorbent assay of CSF were carried out in sham-operated rats and rats with surgically induced focal cerebral ischemia. These groups were further divided into animals that did and did not receive NGF administration or NSC transplant into the cisterna magna. Our results show an up-regulation of class I MHC in the ischemic rats with NGF and NSC administration. The extent of caspase-III immunoreactivity was comparable among three arms in the ischemic rats. Conclusion Readouts of somatosensory evoked potential and the trap channel test illustrated improvements in the neurological function of ischemic rats treated with NGF administration and NSC transplant.

    2012-01-01

    In recent decades, research experiences for undergraduates (REUs) programs have provided students with opportunities to spend a summer working on a research project with a faculty mentor. The aim of these programs has generally been to take up the challenge of the Boyer-2 report to introduce research-based learning into the undergraduate experience (Boyer 1998). Recent efforts have been aimed at encouraging women and underrepresented minorities to pursue STEM careers. With the advent of successful models for online degree programs that can add to the STEM workforce pipeline, there is now the possibility of expanding these research experiences to include the new diverse demographic of previously untapped online learners. Many online learners are working adults, and therefore do not have the same flexibility as traditional undergraduates to attend a summer REU at another institution, nor do they have the opportunity for internships at their home institution. This project is intended to leverage significant developments in rapidly emerging social media; investments in Internet-accessible telescopes for professional and amateur use; and contemporary advances in the learning sciences to build pathways through long-term, collaborative, astronomy research projects. The first stage involves developing initial research protocols and online mentoring infrastructures for establishing an ongoing national program for virtual astronomy internships for undergraduate STEM majors. Underlying this project is a plan for students to work collaboratively alongside active professional and amateur astronomers to conduct original research using remotely controlled and robotic telescopes. We anticipate that by the start of this project, more than 100 robotic and remotely controlled telescopes will exist around the world (mo-www.harvard.edu/OWN, aavso.org/aavsonet, and lcogt.net among others) providing continuous world-wide coverage. We plan to test and iteratively build a successful

    Campbell, Karen; Overeem, Irina; Berlin, Maureen

    2013-04-01

    The United States faces a crisis in education: a dire shortage of students sufficiently prepared in the STEM (Science, Technology, Engineering and Mathematics) disciplines to competitively enter the workforce (National Education Technology Plan, 2010). At the same time, there is increasing demand for well-trained geoscientists in a variety of careers related to the environment and natural resources. Many efforts, including the recently released Earth Science and Climate Literacy Principles, seek to promote better Earth science education, as well as to strengthen the Earth science literacy of the entire US population. Yet even those undergraduate students who choose to major in geology or related geoscience disciplines rarely acquire sufficient quantitative skills to be truly competitive graduate students or professionals. Experience with modeling, during their undergraduate careers, could greatly increase the quantitative literacy of geoscience majors and help them appreciate the real world applicability of mathematics and computational methods in their future careers in the geosciences.

    Periodontal ligament stem cells (PDLSCs) from the periodontal ligament tissue were recently identified as mesenchymal stem cells (MSCs). The capabilities of PDLSCs in periodontal tissue or bone regeneration have been reported, but their immunomodulatory role in T-cell immune responses via dendritic cells (DCs), known as the most potent antigen-presenting cell, has not been studied. The aim of this study is to understand the immunological function of homogeneous human STRO-1 + CD146 + PDLSCs in DC-mediated T-cell immune responses to modulate the periodontal disease process. We utilized highly purified (> 95%) human STRO-1 + CD146 + PDLSCs and human bone marrow mesenchymal stem cells (BMSCs). Each stem cell was co-cultured with human monocyte-derived DCs in the presence of lipopolysaccharide isolated from Porphyromonas gingivalis, a major pathogenic bacterium responsible for periodontal disease, in vitro to examine the immunological effect of each stem cell on DCs and DC-mediated T-cell proliferation. We discovered that STRO-1 + CD146 + PDLSCs, as well as BMSCs, significantly decreased the level of non-classical major histocompatibility complex glycoprotein CD1b on DCs, resulting in defective T-cell proliferation, whereas most human leukocyte antigens and the co-stimulatory molecules CD80 and CD86 in/on DCs were not significantly affected by the presence of BMSCs or STRO-1 + CD146 + PDLSCs. This study unveiled an immunomodulatory role of STRO-1 + CD146 + PDLSCs in negatively regulating DC-mediated T-cell immune responses, demonstrating their potential to be utilized in promising new stem cell therapies. © 2016 John Wiley & Sons A/S.

    Stem cell research has been extensively explored worldwide to enhance human health in medical setting. Nevertheless, there is currently no full understanding of the stem cell knowledge and attitude levels among student nurses in Malaysia. This study aimed to assess the level of stem cell knowledge, attitude toward stem cell application in medicine, and its association with years of education, among Universiti Sains Malaysia (USM) undergraduate nursing students. A cross-sectional study (n = 88) was conducted using self-administered questionnaire consisted of demographic information, stem cells knowledge and attitude statements. Data was analysed using Statistical Package Social Software 20.0. The majority of participants (92%) had moderate knowledge score about stem cells. Many students (33%) worried that stem cell application might cause a harm to humanity yet had a positive (76.1%) attitude towards its therapeutic potential (45.5%). Poor correlation between knowledge and attitude (r = 0.08) indicated that acceptance towards stem cell is not solely based on the knowledge level but also on other factors including religion and culture. Therefore, this study suggests that various educational programs on stem cell should be implemented considering the religion, cultural, social, and behavioural determinants in the population to improve stem cell knowledge and encourage a more positive attitude towards stem cells in medicine among these nursing students.

  17. Science, Technology, Engineering, Math (STEM) in Higher Education from the Perspective of Female Students: An Institutional Ethnography

    Science.gov (United States)

    Parson, Laura J.

    A persistent disadvantage for females is systemically embedded in Science, Technology, Engineering, and Math (STEM) education in postsecondary institutions. As a result, undergraduate women majoring in STEM fields face a uniquely difficult path; yet, for the most part, recommendations made and supported in the literature have focused on recruitment of women to STEM fields or on ways to make women more successful and comfortable in their STEM major. These recommendations have so far proved to be insufficient to remedy a gender gap and serve to replicate the existing male hierarchy. In order to truly make the STEM classroom one in which women are welcome and comfortable and to challenge the existing social and scientific systems, it is necessary to explore and understand the social and political implications embedded within teaching and learning choices. This institutional ethnography addresses that gap. The purpose of this study was to uncover and describe the institutional practices of STEM education at a Midwest research university (MRU) from the standpoint of female undergraduate students. Using the framework of feminist standpoint theory, this study explored the everyday "work" of female undergraduate STEM students to provide a unique perspective on the STEM education teaching and learning environment. Data collection began with in-depth interviews with female undergraduate math and physics students. As the institutional processes shaping undergraduate participant experiences were identified, subsequent data collection included classroom observations, additional interviews with students and faculty, and analysis of the texts that mediate these processes (e.g., syllabi and student handbooks). Data analysis followed Carspecken's process of ethnographic data analysis that began with low-level coding, followed by high-level coding, and concluded by pulling codes together through the creation of themes. Analysis of data led to three key findings. First, undergraduate

    Radiation is an essential topic to the physical sciences yet is often misunderstood by the general public. The last time most people have formal instruction about radiation is as students in high school and this knowledge will be carried into adulthood. Peoples’ conceptions of radiation influence their attitude towards research regarding radiation, radioactivity, and other work where radiation is prevalent. In order to understand students’ ideas about radiation after having left high school, we collected science surveys from nearly 12,000 undergraduates enrolled in introductory science courses over a span of 25 years. This research investigates the relationship between students’ conceptions of radiation and students’ personal beliefs and academic field of study.Our results show that many students in the sample were unable to adequately describe radiation. Responses were typically vague, brief, and emotionally driven. Students’ field of study was found to significantly correlate with their conceptions. Students pursuing STEM majors were 60% more likely to describe radiation as an emission and/or form of energy and cited atomic or radioactive sources of radiation twice as often as non-STEM students. Additionally, students’ personal beliefs also appear to relate to their conceptions of radiation. The most prominent misconception shown was that radiation is a generically harmful substance, which was found to be consistent throughout the duration of the study. In particular, non-science majors in our sample had higher rates of misconceptions, often generalized the idea of radiation into a broad singular topic, and had difficulty properly identifying sources.Generalized ideas of radiation and the inability to properly recognize sources of radiation may contribute to the prevalent misconception that radiation is an inexplicably dangerous substance.

    To document the detection of underlying low-attenuation spinal cord or brain stem injuries in the presence of the "pseudo-CT myelogram sign" (PCMS) on post-mortem computed tomography (PMCT). The PCMS was identified on PMCT in 20 decedents (11 male, nine female; age 3-83 years, mean age 35.3 years) following fatal blunt trauma at a single forensic centre. Osseous and ligamentous craniocervical region injuries and brain stem or spinal cord trauma detectable on PMCT were recorded. PMCT findings were compared to conventional autopsy in all cases. PMCT-detected transection of the brain stem or high cervical cord in nine of 10 cases compared to autopsy (90% sensitivity). PMCT was 92.86% sensitive in detection of atlanto-occipital joint injuries (n=14), and 100% sensitive for atlanto-axial joint (n=8) injuries. PMCT detected more cervical spine and skull base fractures (n=22, and n=10, respectively) compared to autopsy (n=13, and n=5, respectively). The PCMS is a novel description of a diagnostic finding, which if present in fatal craniocervical region trauma, is very sensitive for underlying spinal cord and brain stem injuries not ordinarily visible on PMCT. Its presence may also predict major osseous and/or ligamentous injuries in this region when anatomical displacement is not evident on PMCT. Copyright © 2017 The Royal College of Radiologists.

    The present study addressed concerns over the high risk of university students' academic failure. It examined how perceived academic control and academic emotions predict undergraduate students' academic success, conceptualized as both low dropout intention and high achievement (indicated by GPA). A cross-sectional survey was administered to 883 undergraduate students across all disciplines of a German STEM orientated university. The study additionally compared freshman students (N = 597) vs. second-year students (N = 286). Using structural equation modeling, for the overall sample of undergraduate students we found that perceived academic control positively predicted enjoyment and achievement, as well as negatively predicted boredom and anxiety. The prediction of dropout intention by perceived academic control was fully mediated via anxiety. When taking perceived academic control into account, we found no specific impact of enjoyment or boredom on the intention to dropout and no specific impact of all three academic emotions on achievement. The multi-group analysis showed, however, that perceived academic control, enjoyment, and boredom among second-year students had a direct relationship with dropout intention. A major contribution of the present study was demonstrating the important roles of perceived academic control and anxiety in undergraduate students' academic success. Concerning corresponding institutional support and future research, the results suggested distinguishing incoming from advanced undergraduate students. PMID:28326043

    2017-01-01

    To obtain insight into the transcription factor (TF)-dependent regulation of epiblast stem cells (EpiSCs), we performed ChIP-seq analysis of the genomic binding regions of five major TFs. Analysis of in vivo biotinylated ZIC2, OTX2, SOX2, POU5F1 and POU3F1 binding in EpiSCs identified several new features. (1) Megabase-scale genomic domains rich in ZIC2 peaks and genes alternate with those rich in POU3F1 but sparse in genes, reflecting the clustering of regulatory regions that act at short and long-range, which involve binding of ZIC2 and POU3F1, respectively. (2) The enhancers bound by ZIC2 and OTX2 prominently regulate TF genes in EpiSCs. (3) The binding sites for SOX2 and POU5F1 in mouse embryonic stem cells (ESCs) and EpiSCs are divergent, reflecting the shift in the major acting TFs from SOX2/POU5F1 in ESCs to OTX2/ZIC2 in EpiSCs. (4) This shift in the major acting TFs appears to be primed by binding of ZIC2 in ESCs at relevant genomic positions that later function as enhancers following the disengagement of SOX2/POU5F1 from major regulatory functions and subsequent binding by OTX2. These new insights into EpiSC gene regulatory networks gained from this study are highly relevant to early stage embryogenesis. PMID:28455373

    There is a growing demand for degreed science, technology, engineering and mathematics (STEM) professionals, but the production of degreed STEM students is not keeping pace. Problems exist at every juncture along the pipeline. Too few students choose to major in STEM disciplines. Many of those who do major in STEM drop out or change majors. Females and minorities remain underrepresented in STEM. The success rate of college students who are from low-income background or first-generation students is much lower than that of students who do not face such challenges. Some of those who successfully complete their degree need help in making the transition to the workforce after graduation. A program at Lamar University takes a multidisciplinary approach to addressing these problems. It is designed to recruit, retain and transition undergraduates to careers in STEM, focusing its efforts on five science disciplines and on these "at-risk" students. The program was supported by a 5-year grant from the National Science Foundation and is supported through August 31, 2016 by Lamar University and a grant from ExxonMobil. A formal assessment plan documents the program's success. The program received an award from the Texas Higher Education Board for its contributions towards Closing the Gaps in Higher Education in Texas. This paper describes the program's theoretical framework, research questions, methods, evaluation plan, and instruments. It presents an analysis of the results achieved using these methods and implications for improvements to the program resulting from lessons learned.

    Improving the diversity within the rapidly growing fields of science, technology, engineering, and mathematics (STEM) has become a forefront issue facing collegiate departments today. It is well known that there are large gaps in the participation and performance of minorities, women, and low-income students within these fields and that special attention must be paid in order to close this gap. Since 2005, the Pre-Major in Astronomy Program (Pre-MAP) at the University of Washington (UW) Department of Astronomy has made a concentrated effort to recruit and retain underrepresented undergraduates in STEM, at which it has been very successful. Of course, recruiting these students can be a challenge, as is creating a curriculum and atmosphere that enables undergraduates to successfully participate in real astronomy research during their first or second year at a four-year college. Pre-MAP recruits a significant population of minorities and women into the program. The structure of the seminar is intended to not only provide necessary skills and experience, but also create a collaborative and supportive atmosphere among each cohort. I will discuss the recruitment practices of Pre-MAP as well as the structure of the seminar and how it addresses the goal of early participation and success in STEM research and course work.The intent of this talk is to share our methods so that more programs like Pre-MAP can be adopted successfully in other institutions.

The aim of the study was to explore and document views and experiences of undergraduate students regarding the role of masters students as educators in four Ugandan medical schools. This was a cross-sectional descriptive study using qualitative data collection methods. Eight Focus Group Discussions were conducted among eighty one selected preclinical and clinical students in the consortium of four Ugandan medical schools: Mbarara University of Science and Technology, Makerere College of Health Sciences, Gulu University and Kampala International University, Western Campus. Data analysis was done using thematic analysis. Participants' privacy and confidentiality were respected and participant identifiers were not included in data analysis. Undergraduate students from all the medical schools viewed the involvement of master's students as very important. Frequent contact between masters and undergraduate students was reported as an important factor in undergraduate students' motivation and learning. Despite the useful contribution, master' students face numerous challenges like heavy workload and conflicting priorities. According to undergraduate students in Ugandan medical schools, involvement of master's students in the teaching and learning of undergraduate students is both useful and challenging to masters and undergraduate students. Masters students provide peer mentorship to the undergraduate students. The senior educators are still needed to do their work and also to support the master's students in their teaching role.

    Full Text Available Essential oils of Lippia sidoides, Lippia gracilis and their main chemical components were investigated for in vitro control of Thielaviopsis paradoxa. Mycelial growth and a number of pathogen conidia were inhibited by the essential oil of L. sidoides at all concentrations tested (0.2; 0.5; 1.0; 3.0 µL mL-1. L. sidoides oil contained 42.33% thymol and 4.56% carvacrol, while L. gracilis oil contained 10% thymol and 41.7% carvacrol. Mycelial growth and conidial production of T. paradoxa were completely inhibited by thymol at a 0.3 µL m-1 concentration. The results suggest that thymol could potentially be used for controlling coconut stem bleeding.

The rationale for this article is based upon disproportionate representation among undergraduate physics majors in the United States; women earned only 19.7% of physics undergraduate degrees in 2012. This disparity has been attributed to a variety of factors, including unwelcoming classroom atmospheres, low confidence and self-efficacy, and few female role models in physics academic communities. Recent empirical studies have suggested gender disparities in physics and related STEM fields may be more amenable to social cognitive interventions than previously thought. Social psychologists have found that women improved physics self-concept when adopting a malleable view of intelligence, when they received support and encouragement from family and teachers, and when they experienced interactive learning techniques in communal environments. By exploring research-based evidence for strategies to support women in physics, precollege and university faculty and administrators may apply social cognitive constructs to improve the representation of women in the field.

These projects offer instruction and activities intended to increase diversity in STEM careers. Ke Alahaka, the 2014 summer bridge program, was offered to Native Hawaiian high-school students who indicated an interest in STEM areas. Content workshops were offered in Marine Science, Physics, Biotechnology, and Computer Science and Engineering as well as a Hawaiian Studies course designed to provide a cultural context for the STEM instruction. Focus groups and other program assessments indicate that 50% of the students attending the workshops intend to pursue a STEM major during their undergraduate studies.

  19. A Tri-part Model for Genetics Literacy: Exploring Undergraduate Student Reasoning About Authentic Genetics Dilemmas

    Shea, Nicole A.; Duncan, Ravit Golan; Stephenson, Celeste

    2015-08-01

    Genetics literacy is becoming increasingly important as advancements in our application of genetic technologies such as stem cell research, cloning, and genetic screening become more prevalent. Very few studies examine how genetics literacy is applied when reasoning about authentic genetic dilemmas. However, there is evidence that situational features of a reasoning task may influence how students apply content knowledge as they generate and support arguments. Understanding how students apply content knowledge to reason about authentic and complex issues is important for considering instructional practices that best support student thinking and reasoning. In this conceptual report, we present a tri-part model for genetics literacy that embodies the relationships between content knowledge use, argumentation quality, and the role of situational features in reasoning to support genetics literacy. Using illustrative examples from an interview study with early career undergraduate students majoring in the biological sciences and late career undergraduate students majoring in genetics, we provide insights into undergraduate student reasoning about complex genetics issues and discuss implications for teaching and learning. We further discuss the need for research about how the tri-part model of genetics literacy can be used to explore students' thinking and reasoning abilities in genetics.

  20. Epigenetic silencing of V(DJ recombination is a major determinant for selective differentiation of mucosal-associated invariant t cells from induced pluripotent stem cells.

    Directory of Open Access Journals (Sweden)

    Yutaka Saito

    Full Text Available Mucosal-associated invariant T cells (MAITs are innate-like T cells that play a pivotal role in the host defense against infectious diseases, and are also implicated in autoimmune diseases, metabolic diseases, and cancer. Recent studies have shown that induced pluripotent stem cells (iPSCs derived from MAITs selectively redifferentiate into MAITs without altering their antigen specificity. Such a selective differentiation is a prerequisite for the use of MAITs in cell therapy and/or regenerative medicine. However, the molecular mechanisms underlying this phenomenon remain unclear. Here, we performed methylome and transcriptome analyses of MAITs during the course of differentiation from iPSCs. Our multi-omics analyses revealed that recombination-activating genes (RAG1 and RAG2 and DNA nucleotidylexotransferase (DNTT were highly methylated with their expression being repressed throughout differentiation. Since these genes are essential for V(DJ recombination of the T cell receptor (TCR locus, this indicates that nascent MAITs are kept from further rearrangement that may alter their antigen specificity. Importantly, we found that the repression of RAGs was assured in two layers: one by the modulation of transcription factors for RAGs, and the other by DNA methylation at the RAG loci. Together, our study provides a possible explanation for the unaltered antigen specificity in the selective differentiation of MAITs from iPSCs.

    The Advancing Space Science through Undergraduate Research Experience (ASSURE) summer REU program is an NSF-funded REU site at the Space Sciences Lab at UC Berkeley that first started in summer 2014. The program recruits students from all STEM majors, targeting underserved students including community college students and first-generation college students. The students have little or no research experience and a wide variety of academic backgrounds, but have a shared passion for space sciences and astronomy. We will describe our program's structure and the components we have found successful in preparing and supporting both the students and their research advisors for their summer research projects. This includes an intensive first week of introductory lectures and tutorials at the start of the program, preparing students for working in an academic research environment. The program also employs a multi-tiered mentoring system, with layers of support for the undergraduate student cohort, as well as graduate student and postdoctoral research advisors.

    Cancer is now viewed as a stem cell disease. There is still no consensus on the metabolic characteristics of cancer stem cells, with several studies indicating that they are mainly glycolytic and others pointing instead to mitochondrial metabolism as their principal source of energy. Cancer stem cells also seem to adapt their metabolism to microenvironmental changes by conveniently shifting energy production from one pathway to another, or by acquiring intermediate metabolic phenotypes. Determining the role of cancer stem cell metabolism in carcinogenesis has become a major focus in cancer research, and substantial efforts are conducted towards discovering clinical targets.

    We explored whether matching of human leukocyte antigen (HLA) haplotypes between the recipient and donor of hematopoietic stem cell transplantation (HSCT) predicted by C4 and MICA typing is associated with the incidence of acute graft versus host disease (aGVHD). DNA preparations collected from a total of 81 recipient and donor pairs were used for PCR-based C4 subtyping and/or MICA sequence-based typing. Incidences of aGVHD were compared according to C4 and MICA matching. The six most common MICA alleles were MICA*008:01, *010:01, *002:01, *004, *009:01/049, and *012:01. Among the 59 unrelated pairs, HLA alleles were matched in 34 (57.6%). C4 subtypes were identical between the recipient and donor in 28 (82.4%) HLA-matched unrelated pairs, while MICA genotypes were matched in all HLA-matched unrelated pairs. In the 22 HLA-matched related pairs, all recipients showed identical C4 subtypes with their respective donors. In multivariate analysis, C4 mismatch was a significant risk factor associated with the development of aGVHD in unrelated HSCT (hazard ratio=3.24, P=0.006). PCR-based C4 subtyping is a simple method for assessing the genetic identity of the HLA region between a recipient and unrelated donor. This test would be also useful for prediction of aGVHD in HSCT.

    The undergraduate curriculum in psychology profoundly reflects and shapes the discipline. Yet, reliable information on the undergraduate psychology curriculum has been difficult to acquire due to insufficient research carried out on unrepresentative program samples with disparate methods. In 2014, APA launched the first systematic effort in a decade to gather national data on the psychology major and program outcomes. We surveyed a stratified random sample of department chairs/coordinators of accredited colleges and universities in the United States that offer undergraduate courses and programs in psychology. A total of 439 undergraduate psychology programs (45.2%) completed the survey. This article summarizes, for both associate and baccalaureate programs, the results of the Undergraduate Study in Psychology. Current practices concerning the introductory course, the courses offered, core requirements, the psychology minor, and tracks/concentrations are presented. The frequency of formal program reviews and program-level assessment methods are also addressed. By extending prior research on the undergraduate curriculum, we chronicle longitudinal changes in the psychology major over the past 20 years. (c) 2016 APA, all rights reserved).

    Non-science major students represent individuals who will become productive members of society in non-science fields including our business leaders, policy makers, and teachers. Their college non-major science courses are often the last formal instruction they will receive in science. As such, it important to understand what students already know about science and provide instruction that is engaging and helps them gain a greater appreciation for doing science. We report on a study of almost 12,000 undergraduate students enrolled in introduction astronomy courses from 1989 - 2014, most of who were freshman or sophomore students. Almost every year during the 25 year period, students were asked to complete an in-class survey that included basic science content questions and attitude towards science questions. They were also asked to write a response to the question, “What does it mean to study something scientifically?”Sixty-five percent of responses were meaningful and considered to be on target. In their responses 16% of students described science as a way of gaining knowledge or learning about something. Twenty three percent of respondents described science as using observations or experimentation and 10% described it as involving a hypothesis. Only 8% of respondents mentioned data analysis while 6% described using data or evidence. Four percent of respondents mentioned science was a way to solve problems and 4% described science as being systematic. Students who were self-reported STEM majors (Pre-med, engineering, math, and science majors) more often mentioned that science is an empirical technique as well as the use of hypotheses in science STEM majors also mentioned data twice as often as non-STEM majors in their responses. Education majors, who made up 6% of the sample, had the least descriptive answers overall, and were the group who most often not include aspects that were essential to studying science.Gathering this information has helped characterize

  9. [Art in undergraduate medical education].

    Fjellstad, Kenneth; Isaksen, Tor Olav; Frich, Jan C

    2003-08-28

    During the last decades attempts have been made at integrating art in medical education. What should be the form, content and objectives of such teaching? We address this question on the basis of a review of articles in medical journals from 1990 until May 2001 about art and undergraduate medical education. A common reason for integrating art in undergraduate medical education is that art may act as a balance to the dominance of natural science. One pedagogical approach is to use art as a tool for training skills. Many articles emphasise that teaching art should also contribute to the personal and professional development of medical students. The majority of articles report on courses in literature and medicine. Art is often taught in small or medium-sized groups; courses may last from single lessons to programmes over years. The aim of art courses may be the development of skills, but also one of facilitating personal growth and professional development.

  10. Emergence, Learning Difficulties, and Misconceptions in Chemistry Undergraduate Students' Conceptualizations of Acid Strength

    Tümay, Halil

    2016-03-01

    Philosophical debates about chemistry have clarified that the issue of emergence plays a critical role in the epistemology and ontology of chemistry. In this article, it is argued that the issue of emergence has also significant implications for understanding learning difficulties and finding ways of addressing them in chemistry. Particularly, it is argued that many misconceptions in chemistry may derive from students' failure to consider emergence in a systemic manner by taking into account all relevant factors in conjunction. Based on this argument, undergraduate students' conceptions of acids, and acid strength (an emergent chemical property) were investigated and it was examined whether or not they conceptualized acid strength as an emergent chemical property. The participants were 41 third- and fourth-year undergraduate students. A concept test and semi-structured interviews were used to probe students' conceptualizations and reasoning about acid strength. Findings of the study revealed that the majority of the undergraduate students did not conceptualize acid strength as an emergent property that arises from interactions among multiple factors. They generally focused on a single factor to predict and explain acid strength, and their faulty responses stemmed from their failure to recognize and consider all factors that affect acid strength. Based on these findings and insights from philosophy of chemistry, promoting system thinking and epistemologically sound argumentative discourses among students is suggested for meaningful chemical education.

    The present study was undertaken to investigate the hepatoprotective effect of the methanol extract of Cotinus coggygria Scop. in rats exposed to the hepatotoxic compound pyrogallol. Assessed with the alkaline version of the comet assay, 1000 and 2000mg/kg body weight (bw) of the extract showed a low level of genotoxicity, while 500mg/kg bw of the extract showed no genotoxic potential. Quantitative HPLC analysis of phenolic acids and flavonoids in the methanol extract of C. coggygria showed that myricetin was a major component. To test the hepatoprotective effect, a non-genotoxic dose of the C. coggygria extract and an equivalent amount of synthetic myricetin, as present in the extract, were applied either 2 or 12h prior to administration of 100mg/kg bw of pyrogallol. The extract and myricetin promoted restoration of hepatic function by significantly reducing pyrogallol-induced elevation in the serum enzymes AST, ALT, ALP and in total bilirubin. As measured by the decrease in total score and tail moment, the DNA damage in liver was also reduced by the extract and by myricetin. Our results suggest that pro-surviving Akt activity and STAT3 protein expression play important roles in decreasing DNA damage and in mediating hepatic protection by the extract. These results suggest that myricetin, as a major component in the extract, is responsible for the antigenotoxic and hepatoprotective properties of the methanol extract of C. coggygria against pyrogallol-induced toxicity.

  12. The Transformative Impact of Undergraduate Research Mentoring on Students and the Role of the Council on Undergraduate Research (CUR) in Supporting Faculty Mentors

    Science.gov (United States)

    Fox, L. K.; Singer, J.

    2015-12-01

    Undergraduate Research (UR) is broadly accepted as a high impact educational practice. Student participation in UR contributes to measurable gains in content knowledge and skills/methodology, oral and written communication skills, problem solving and critical thinking, self-confidence, autonomy, among others. First-generation college students and students from underrepresented minorities that participate in UR are more likely to remain in STEM majors, persist to graduation, and pursue graduate degrees. While engagement in the research process contributes to these outcomes, the impact of the interaction with the faculty mentor is critical. A number of studies provide evidence that it is the relationship that forms with the faculty mentor that is most valued by students and strongly contributes to their career development. Faculty mentors play an important role in student development and the relationship between mentor and student evolves from teacher to coach to colleague. Effective mentoring is not an inherent skill and is generally not taught in graduate school and generally differs from mentoring of graduate students. Each UR mentoring relationship is unique and there are many effective mentoring models and practices documented in the literature. The Council on Undergraduate Research (CUR) has a long history of supporting faculty who engage in research with undergraduates and offers resources for establishing UR programs at individual, departmental, and institutional levels. The Geosciences Division of CUR leads faculty development workshops at professional meetings and provides extensive resources to support geosciences faculty as UR mentors (http://serc.carleton.edu/NAGTWorkshops/undergraduate_research/index.html). Examples of effective mentoring strategies are highlighted, including a model developed by SUNY- Buffalo State that integrates mentoring directly into the evaluation of UR.

  13. Identification of QTLs for resistance to sclerotinia stem rot and BnaC.IGMT5.a as a candidate gene of the major resistant QTL SRC6 in Brassica napus.

    Directory of Open Access Journals (Sweden)

    Jian Wu

    Full Text Available Stem rot caused by Sclerotinia sclerotiorum in many important dicotyledonous crops, including oilseed rape (Brassica napus, is one of the most devastating fungal diseases and imposes huge yield loss each year worldwide. Currently, breeding for Sclerotinia resistance in B. napus, as in other crops, can only rely on germplasms with quantitative resistance genes. Thus, the identification of quantitative trait locus (QTL for S. sclerotiorum resistance/tolerance in this crop holds immediate promise for the genetic improvement of the disease resistance. In this study, ten QTLs for stem resistance (SR at the mature plant stage and three QTLs for leaf resistance (LR at the seedling stage in multiple environments were mapped on nine linkage groups (LGs of a whole genome map for B. napus constructed with SSR markers. Two major QTLs, LRA9 on LG A9 and SRC6 on LG C6, were repeatedly detected across all environments and explained 8.54-15.86% and 29.01%-32.61% of the phenotypic variations, respectively. Genotypes containing resistant SRC6 or LRA9 allele showed a significant reduction in disease lesion after pathogen infection. Comparative mapping with Arabidopsis and data mining from previous gene profiling experiments identified that the Arabidopsis homologous gene of IGMT5 (At1g76790 was related to the SRC6 locus. Four copies of the IGMT5 gene in B. napus were isolated through homologous cloning, among which, only BnaC.IGMT5.a showed a polymorphism between parental lines and can be associated with the SRC6. Furthermore, two parental lines exhibited a differential expression pattern of the BnaC.IGMT5.a gene in responding to pathogen inoculation. Thus, our data suggested that BnaC.IGMT5.a was very likely a candidate gene of this major resistance QTL.

    2017-12-01

    Within STEM fields, employers are reporting a widening gap in the workforce readiness of new graduates. As departments continue to be squeezed with new requirements, chasing the latest technologies and scientific developments and constrained budgets, formal undergraduate programs struggle to fully prepare students for the workforce. One major mechanisms to address gaps within formal education is in life-long learning. Most technical and professional fields have life-long learning requirements, but it is not common in the geosciences, as licensing requirements remain limited. By introducing the concept of career self-management and life-long learning into the formal education experience of students, we can build voluntary engagement and shift some of the preparation burden from existing degree programs. The Geoscience Online Learning Initiative (GOLI) seeks to extend professional life-long learning into the formal education realm. By utilizing proven, effective means to capture expert knowledge, the GOLI program constructs courses in the OpenEdX platform, where the content authors and society staff continuously refine the material into effective one- to two-hour long asynchronous modules. The topical focus of these courses are outside of the usual scope of the academic curriculum, but are aligned with applied technical or professional issues. These courses are provided as open education resources, but also qualify for CEUs as the ongoing professional microcredential in the profession. This way, interested faculty can utilize these resources as focused modules in their own course offerings or students can engage in the courses independently and upon passing the assessments and paying of a nominal fee, be awarded CEUs which count towards their professional qualifications. Establishing a continuum of learning over one's career is a critical cultural change needed for students to succeed and be resilient through the duration of a career. We will examine how this

  20. Research Experience for Undergraduates: A Non-Traditional Approach

    Carrick, T. L.; Miller, K. C.; Hagedorn, E.; Velasco, A. A.

    2012-12-01

    Research experiences for undergraduates (REUs) have been documented to be an effective way to increase student retention in the Science, Technology, Engineering and Mathematics (STEM) by exposing students to research. REUs typically run during the summer months, allowing students to travel to different universities away from their home institutions. We created an REU program, Pathways Research Experience for undergraduates Program (PREP) that ran during the fall and spring academic semesters and focused on the geosciences. These students were provided with a monthly stipend to work with a research mentor, and they were required to attend a weekly professional development meeting led by the Pathways PIs and the program coordinator. The weekly training program focused on research skills, presentation skills, and graduate school preparation. Since a majority of students at University of Texas at El Paso (a Hispanic Serving Institution with 70% Hispanic and 10% Mexican students) must work outside the university while attending college, the stipends enabled students to remain on campus to "work", with the hope that this may contribute to their overall academic success. By spending more time on campus, the participants were able to interact more with faculty and other students, both at the undergraduate and graduate levels. Participants were chosen on a basis of GPA and the contents of an application that included a statement of purpose, a resume, a transcript, and at least one letter of recommendation. Once the student was selected, they were required to find a mentor and research project. Through an analysis of surveys, we have found that participants enjoy the meetings, which gave them a sense of belonging to a group, and an additional source of academic support. Participants were also expected to take part in outreach activities as part of our goal to create a geosciences network in El Paso. With this REU approach, we believe that our success rate suggests that this

    We conducted a prospective, phase II, multicenter, single-arm study to evaluate the efficacy and safety of deferasirox in patients age >2 to 1000 µg/L; cardiac MRI T2* deferasirox at an initial dose of 10 mg/kg/day, with up-titration to a maximum of 20 mg/kg/day. The study continued for 52 weeks and included a total of 27 patients (mean age, 9.1 ± 3.8 years; 70.4% male). One patient (3.7%) was lost to follow-up. The majority of patients (n = 20; 74.1%) were able to achieve the intended dose of 20 mg/kg/day. No deaths occurred. A total of 134 adverse events (AEs) were reported in 25 patients (92.6%) during the study. The majority of patients had grade 1 or 2 AEs, with only 8 patients (29.6%) experiencing grade 3 AEs. Only 10 AEs occurring in 4 patients (14.8%) were suspected to be related to deferasirox (ALT/AST increase, n = 4; urinary tract infection, n = 1). The deferasirox dose had to be adjusted or interrupted for 6 AEs occurring in 4 patients (14.8%). A total of 6 serious AEs occurred in 3 patients (11.1%), none of which were suspected to be related to deferasirox. From baseline to week 52, there were decreases in median concentrations of alanine aminotransferase (ALT), from 30.0 to 17.0 IU/L, and aspartate aminotransferase (AST), from 35.5 to 26.0 IU/L. Median serum creatinine and cystatin C concentrations were similar at baseline and week 52. There was a continuous and significant decrease in median serum ferritin level from 1718.0 µg/L at baseline to 845.3 µg/L following 52 weeks of therapy (P deferasirox treatment at doses up to 20 mg/kg/day reduces the iron burden in children with TM post-HSCT, with a manageable safety profile.

    2011-12-01

    Low participation and performance in science, technology, engineering, and mathematics (STEM) fields by U.S. citizens are widely recognized as major problems with substantial economic, political, and social ramifications. Studies of collegiate interventions designed to broaden participation in STEM fields suggest that participation in undergraduate research is a key program component that enhances such student outcomes as undergraduate GPA, graduation, persistence in a STEM major, and graduate school enrollment. However, little is known about the mechanisms that are responsible for these positive effects. The current study hypothesizes that undergraduate research participation increases scientific self-efficacy and scientific research proficiency. This hypothesis was tested using data obtained from a survey of minority students from several STEM intervention programs that offer undergraduate research opportunities. Students were surveyed both prior to and following the summer of 2010. Factor analysis was used to examine the factor structure of participants' responses on scientific self-efficacy and scientific research proficiency scales. Difference-in-difference analysis was then applied to the resulting factor score differences to estimate the relationship of summer research participation with scientific self-efficacy and scientific research proficiency. Factor analytic results replicate and further validate previous findings of a general scientific self-efficacy construct (Schultz, 2008). While the factor analytic results for the exploratory scientific research proficiency scale suggest that it was also a measureable construct, the factor structure was not generalizable over time. Potential reasons for the lack of generalizability validity for the scientific research proficiency scale are explored and recommendations for emerging scales are provided. Recent restructuring attempts within federal science agencies threaten the future of STEM intervention programs

    The NSF-funded GEodesy Tools for Societal Issues (GETSI) project is developing modules for use in introductory and majors-level courses that emphasize a broad range of geodetic data and quantitative skills applied to societally important issues of climate change, natural hazards, and water resources (serc.carleton.edu/getsi). The modules fill gaps in existing undergraduate curricula, which seldom include geodetic methods. Published modules are "Ice mass and sea level changes", "Imaging active tectonics with LiDAR and InSAR", "Measuring water resources with GPS, gravity, and traditional methods", "Surface process hazards", and "GPS, strain, and earthquakes". The GETSI Field Collection features geodetic field techniques. The field-oriented module "Analyzing high resolution topography with terrestrial laser scanning (TLS) and structure from motion (SfM)" is already published and "High precision positioning with static and kinematic GPS" will be published in 2017. Modules are 1-3 weeks long and include student exercises, data analysis, and extensive supporting materials. For field modules, prepared data sets are provided for courses that cannot collect field data directly. All modules were designed and developed by teams of faculty and content experts and underwent rigorous review and classroom testing. Collaborating institutions are UNAVCO (which runs NSF's Geodetic Facility), Indiana University, Mt San Antonio College, and Idaho State University. Science Education Resource Center (SERC) is providing assessment and evaluation expertise. If future funding is successful, the topic range will be expanded (e.g., volcanic hazards, more water resources, and ecological applications of geodesy). Funding to date has been provided by NSF's TUES (Transforming Undergraduate Education in STEM) and IUSE (Improving Undergraduate STEM Education).

  6. Perceived mathematical ability under challenge: a longitudinal perspective on sex segregation among STEM degree fields.

    2015-01-01

    Students' perceptions of their mathematics ability vary by gender and seem to influence science, technology, engineering, and mathematics (STEM) degree choice. Related, students' perceptions during academic difficulty are increasingly studied in educational psychology, suggesting a link between such perceptions and task persistence. Despite interest in examining the gender disparities in STEM, these concepts have not been considered in tandem. In this manuscript, we investigate how perceived ability under challenge-in particular in mathematics domains-influences entry into the most sex-segregated and mathematics-intensive undergraduate degrees: physics, engineering, mathematics, and computer science (PEMC). Using nationally representative Education Longitudinal Study of 2002 (ELS) data, we estimate the influence of perceived ability under challenging conditions on advanced high school science course taking, selection of an intended STEM major, and specific major type 2 years after high school. Demonstrating the importance of specificity when discussing how gender influences STEM career pathways, the intersecting effects of gender and perceived ability under mathematics challenge were distinct for each scientific major category. Perceived ability under challenge in secondary school varied by gender, and was highly predictive of selecting PEMC and health sciences majors. Notably, women's 12th grade perceptions of their ability under mathematics challenge increased their probability of selecting PEMC majors over and above biology. In addition, gender moderated the effect of growth mindset on students' selection of health science majors. Perceptions of ability under challenge in general and verbal domains also influenced retention in and declaration of certain STEM majors. The implications of these results are discussed, with particular attention to access to advanced scientific coursework in high school and interventions aimed at enhancing young women's perceptions of

Women in PROGRESS attended an off-site weekend workshop and gained access to a network of volunteer female scientific mentors from on- and off-campus (i.e., university faculty, graduate students, and outside scientific professionals. The results indicate that women in PROGRESS had larger networks of developmental mentoring relationships and were more likely to be mentored by faculty members and peers than matched controls. Mentoring support from a faculty member benefited early-undergraduate women by strengthening their scientific identity and their interest in earth and environmental science career pathways. Further, support from a faculty mentor had a positive indirect impact on women's scientific persistence intentions, through strengthened scientific identity development. These results imply that first- and second- year undergraduate women's mentoring support networks can be enhanced through provision of protégé training and access to more senior women in the sciences willing to provide mentoring support.

  17. Increasing College Students' Interest and Engagement in STEM: A Comparison of Strategies for Challenging STEM Stereotypes

    Science.gov (United States)

    Shin, Jiyun Elizabeth L.

    Increasing science, technology, engineering, and mathematics (STEM) graduates has become an important part of the education agenda in the U.S. in recent years. Stereotypes about STEM (i.e., belief that STEM abilities are innate, and that European American men are best suited for STEM) have been identified as one of the critical factors that may contribute to low recruitment and retention of STEM students. Drawing from the literatures on biological essentialism and role models, this study compared different strategies for challenging STEM stereotypes among undergraduate students in STEM and non-STEM fields. STEM stereotypes were challenged directly with research articles that provided non-biological explanations for STEM success and interest (a strategy used in the essentialism research) and indirectly with biographies of successful STEM role models who are underrepresented in their field and who succeeded through hard work (a strategy used in the role model research). Contrary to the predictions, exposure to the role model biographies, research articles, or combination of both did not have statistically significant effects on participants' reported STEM interest and academic intentions. Possible explanations for the lack of significant findings as well as suggestions for developing effective interventions to promote STEM engagement among students are discussed.

  18. Accreditation standards for undergraduate forensic science programs

    Miller, Marilyn Tebbs

    Undergraduate forensic science programs are experiencing unprecedented growth in numbers of programs offered and, as a result, student enrollments are increasing. Currently, however, these programs are not subject to professional specialized accreditation. This study sought to identify desirable student outcome measures for undergraduate forensic science programs that should be incorporated into such an accreditation process. To determine desirable student outcomes, three types of data were collected and analyzed. All the existing undergraduate forensic science programs in the United States were examined with regard to the input measures of degree requirements and curriculum content, and for the output measures of mission statements and student competencies. Accreditation procedures and guidelines for three other science-based disciplines, computer science, dietetics, and nursing, were examined to provide guidance on accreditation processes for forensic science education programs. Expert opinion on outcomes for program graduates was solicited from the major stakeholders of undergraduate forensic science programs-forensic science educators, crime laboratory directors, and recent graduates. Opinions were gathered by using a structured Internet-based survey; the total response rate was 48%. Examination of the existing undergraduate forensic science programs revealed that these programs do not use outcome measures. Of the accreditation processes for other science-based programs, nursing education provided the best model for forensic science education, due primarily to the balance between the generality and the specificity of the outcome measures. From the analysis of the questionnaire data, preliminary student outcomes, both general and discipline-specific, suitable for use in the accreditation of undergraduate forensic science programs were determined. The preliminary results were reviewed by a panel of experts and, based on their recommendations, the outcomes

  19. Persistence of deaf students in science, technology, engineering, and mathematics undergraduate programs

    Marchut, Amber E.

    Diversifying the student population and workforce under science, technology, engineering, and mathematics (STEM) is a necessity if innovations and creativity are to expand. There has not been a lot of literature regarding Deaf students in STEM especially regarding understanding how they persist in STEM undergraduate programs to successfully become STEM Bachelor of Science degree recipients. This study addresses the literature gap by investigating six students' experiences as they navigate their STEM undergraduate programs. The investigation uses narrative inquiry methodology and grounded theory method through the lens of Critical Race Theory and Critical Deaf Theory. Using videotaped interviews and observations, their experiences are highlighted using narratives portraying them as individuals surviving in a society that tends to perceive being deaf as a deficit that needs to be treated or cured. The data analysis also resulted in a conceptual model providing a description of how they persist. The crucial aspect of the conceptual model is the participants learned how to manage being deaf in a hearing-dominated society so they can reach their aspirations. The essential blocks for the persistence and managing their identities as deaf undergraduate STEMs include working harder, relying on familial support, and affirming themselves. Through the narratives and conceptual model of the six Deaf STEM undergraduates, the goal is to contribute to literature to promote a better understanding of the persistence of Deaf students, members of a marginalized group, as they pursue their dreams.

    Blood transfusion is the most common procedure performed in American hospitals, and transfusions are commonly ordered by physicians without formal training in transfusion medicine. Several transfusion medicine curricula have been proposed, including those developed through the Transfusion Medicine Academic Awards (TMAA). To our knowledge, no comprehensive study has assessed how transfusion medicine is incorporated into undergraduate medical education. We conducted an online survey to determine the manner in which transfusion medicine is incorporated into American undergraduate medical education. The survey was e-mailed to administrators of medical education at all of the 129 American medical schools accredited by the Association of American Medical Colleges. Eighty-six (67%) of the 129 identified medical school administrators responded. Seventy-one (83%) of the 86 administrators reported that their undergraduate medical education curriculum provides didactic lectures in transfusion medicine, with 48% of medical schools providing 1 or 2 hours of lecture-based instruction. A minority reported small group sessions devoted to transfusion medicine topics. While a slim majority reported the availability of transfusion medicine electives, only one of 84 administrators reported that such a rotation is required. Seventy-six of 83 (92%) administrators were unfamiliar with either the 1989 or the 1995 TMAA transfusion medicine curricula. Transfusion medicine content in American undergraduate medical education is variable and the influence of the TMAA program on contemporary medical school curricula is questionable. Future efforts in this area should focus on standardizing and improving undergraduate medical education in transfusion medicine. © 2011 American Association of Blood Banks.

    Since 2005, the NOAA Ernest F. Hollings Undergraduate Scholarship Program has provided tuition support and paid summer internship opportunities at NOAA to exceptional students majoring in the geosciences. The purpose of the scholarship program is to train students in NOAA mission fields. Multiple methods were used to track the career trajectories of Hollings alumni, including mining LinkedIn data, conducting an impact analysis based on a professionally developed web-based evaluation survey, and a web-based alumni update system. At least one postgraduate record was recorded for 80% of Hollings Scholarship alumni. Of the alumni reached, more than 75% continued on to graduate school in a NOAA mission field, and 86% of those graduate degrees were in a NOAA mission field or other STEM field. More than 60% of alumni had at least one professional record, with the most alumni working in private industry, followed by nongovernmental organizations and federal, state and local government.

  4. The STEM Lecture Hall: A Study of Effective Instructional Practices for Diverse Learners

    Science.gov (United States)

    Reimer, Lynn Christine

    First-generation, low-income, underrepresented minority (URM) and female undergraduates are matriculating into science, technology, engineering, and math (STEM) majors at unprecedented levels. However, a disproportionate number of these students end up graduating in non-STEM disciplines. Attrition rates have been observed to spike in conjunction with introductory STEM courses in chemistry, biology, and physics. These "gateway" courses tend to be housed in large, impersonal lecture halls. First-generation and URM students struggle in this environment, possibly because of instructors' reliance on lecture-based content delivery and rote memorization. Recent social psychological studies suggest the problem may be related to cultural mismatch, or misalignment between independent learning norms typical of American universities and interdependent learning expectancies for first-generation and URM students. Value-affirming and utility-value interventions yield impressive academic achievement gains for these students. These findings overlap with a second body of literature on culturally responsive instruction. Active gateway learning practices that emphasize interactive instruction, frequent assessment, and epistemological instruction can be successful because of their propensity to incorporate values affirming and utility-value techniques. The present study observed instruction for gateway STEM courses over a three-year period at the University of California, Irvine (N = 13,856 undergraduates in 168 courses). Exploratory polychoric factor analysis was used to identify latent variables for observational data on gateway STEM instructional practices. Variables were regressed on institutional student data. Practices implemented in large lecture halls fall into three general categories: Faculty-Student Interaction, Epistemological Instruction, and Peer Interaction . The present study found that Faculty-Student Interaction was negatively associated with student outcomes for

    Spatial visualization is an essential skill in the STEM disciplines, including the geological sciences. Undergraduate students, including geoscience majors in upper-level courses, bring a wide range of spatial skill levels to the classroom. Students with weak spatial skills may struggle to understand fundamental concepts and to solve geological problems with a spatial component. However, spatial thinking skills are malleable. Using strategies that have emerged from cognitive science research, we developed a set of curricular materials that improve undergraduate geology majors' abilities to reason about 3D concepts and to solve spatially complex geological problems. Cognitive science research on spatial thinking demonstrates that predictive sketching, making visual comparisons, gesturing, and the use of analogy can be used to develop students' spatial thinking skills. We conducted a three-year study of the efficacy of these strategies in strengthening the spatial skills of students in core geology courses at three universities. Our methodology is a quasi-experimental quantitative design, utilizing pre- and post-tests of spatial thinking skills, assessments of spatial problem-solving skills, and a control group comprised of students not exposed to our new curricular materials. Students taught using the new curricular materials show improvement in spatial thinking skills. Further analysis of our data, to be completed prior to AGU, will answer additional questions about the relationship between spatial skills and academic performance, spatial skills and gender, spatial skills and confidence, and the impact of our curricular materials on students who are struggling academically. Teaching spatial thinking in the context of discipline-based exercises has the potential to transform undergraduate education in the geological sciences by removing one significant barrier to success.

    Most Science, Technology, Engineering and Mathematics (STEM) disciplines have a direct recruiting method of high school science courses to supply their undergraduate majors. However, recruitment and retention of students into geoscience academic programs, who will be the future workforce, remains an important issue. The geoscience community is reaching a critical point in its ability to supply enough geoscientists to meet the current and near-future demand. Previous work done by Houlton (2010) determined that undergraduate geoscience majors follow distinct pathways when pursuing their degree and career. These pathways are comprised of students' interests, experiences, goals and career aspirations, which are depicted in six pathway steps. Three population groups were determined from the original 17 participants, which exhibited differences in pathway trajectories. Continued data collection efforts developed and refined the pathway framework. As part of an informal workshop activity, data were collected from 27 participants who are underrepresented minority early-career and future faculty in the geosciences. In addition, 20 geoscience departments' Heads and Chairs participated in an online survey about their pathway trajectories. Pathways were determined from each of these new sample populations and compared against the original geoscience undergraduate student participants. Several pathway components consistently spanned across sample populations. Identification of these themes have illuminated broad geoscience-related interests, experiences and aspirations that can be used to broadly impact recruitment and retention initiatives for our discipline. Furthermore, fundamental differences between participants' ages, stages in career and racial/ethnic backgrounds have exhibited subtle nuances in their geoscience pathway trajectories. In particular, those who've had research experiences, who think "creativity" is an important aspect of a geoscience career and those who

    In the United States, men outnumber women in many science and engineering fields by nearly 3 to 1. In fields like physics or the geosciences, the gender gap can be even wider. Previous studies have identified the early college years as a critical point where many women exit STEM disciplines. An interdisciplinary team including experts in the geosciences, psychology, education, and STEM persistence have recently begun a 5-year project focused on understanding whether mentoring can increase the interest, persistence, and achievement of undergraduate women in the geosciences. The program focuses on mentoring first and second year female undergraduate students from three universities in Colorado and Wyoming and four universities in North and South Carolina. The mentoring program includes a weekend workshop, access to professional women across geoscience fields and both in-person and virtual peer networks. The first weekend workshops will be held in October 2015. We will present an overview of the major components and lessons learned from these workshops and showcase the web center, including the online peer-networking forum.

  8. Short-term, informal, and low-stakes scientific laboratory and field experiences improve STEM student retention and academic success

    Formal internship experiences strongly improve student success in the STEM fields. Classical programs like NSF's Research Experiences for Undergraduates are highly successful for traditional and non-traditional students. Moreover when early undergraduate and at-risk (e.g., low income, academically-challenged) students engage in these experiences, their career paths are re-enforced or changed, academic progress and retention improves, and they are encouraged to continue into graduate school. Students build connections to their course-based learning and experience the life of a working scientist. However, NSF formal experiences are relatively expensive to provide (>5000 per student per experience) and are available to fewer than 5% of geoscience majors each year. Although other funded formal internship opportunities exist, they are likely available to no more than 10% of total enrolled geoscience students. These high-quality programs cannot impact enough early undergraduate students to encourage their remaining in science and improve the current overall retention and graduation rates in the US. Savannah State University faculty successfully completed multiple grants funding low-stakes undergraduate field-science experiences. These short-term (semester to year), part-time (5-10h/week) experiences provide similar classroom-to-real-world science connections, offer students direct laboratory and field experiences, build skill sets, and provide a small source of revenue assisting financially-challenged students to stay on campus rather than seeking off-campus employment. For a much lower investment in time and grant resources (500-1500 per student per experience), participant graduation rates exceeded 80%, well above the university 27-34% graduation rate during the same time period. Relatively small infusions of research dollars targeting undergraduate experiences in the field and laboratory could significantly impact long-term student outcomes in STEM disciplines. These

    1997-12-01

    The Council on Undergraduate Research promotes and assists development of collaborative student/faculty research at primarily undergraduate colleges and universities. Most science educators today accept such research as a critical component of an undergraduate science education. Research provides the primary opportunity for students to engage in the practice of science. We can draw an analogy between sports training and the education of young scientists. We cannot train future tennis players exclusively by providing them with lectures on tennis and supervising them performing skill-development drills. To become skilled at their game, tennis players must engage in active competition. Similarly, young scientists must engage in the enterprise that affords our understanding of the physical universe. Only by participating in scientific investigation can students understand the nature of science and become scientists.

    Iron overload is well documented in patients with β-thalassemia major, and patients who have undergone hematopoietic stem cell transplantation (HSCT) remain at risk as a result of pre- and immediate post-HSCT transfusions. This is a prospective, randomized, 1-year clinical trial that compares the efficacy and safety of the once-daily oral iron chelator deferasirox versus phlebotomy for the treatment of iron overload in children with β-thalassemia major following HSCT. Patients (aged 12.4 years) received deferasirox (n = 12, 10 mg/kg/day starting dose) or phlebotomy (n = 14, 6 ml/kg/2 weeks) for 1 year. In two and five patients, deferasirox dose was increased to 15 and 20 mg/kg/day, respectively. Magnetic resonance imaging (MRI)-assessed liver iron concentration (LIC) decreased with deferasirox (mean 12.5 ± 10.1 to 8.5 ± 9.3 mg Fe/g dry weight [dw]; P = 0.0005 vs. baseline) and phlebotomy (10.2 ± 6.8 to 8.3 ± 9.2 mg Fe/g dw; P = 0.05). LIC reductions were greater with deferasirox than with phlebotomy for patients with baseline serum ferritin 1,000 ng/ml or higher (-8.1 ± 1.5 vs. -3.5 ± 5.7 mg Fe/g dw; P = 0.048). Serum ferritin and non-transferrin-bound iron also decreased significantly. In two patients with severe cardiac siderosis, a clinically relevant improvement in myocardial T2* was seen, following phlebotomy and deferasirox therapy (n = 1 each). Adverse effects with deferasirox were skin rash, gastrointestinal upset, and increased liver function tests (all n = 1), while those for phlebotomy were difficulty with venous access (n = 4) and distress during procedure (n = 1). Parents of 13/14 children receiving phlebotomy wished to switch to deferasirox, with 1/14 being satisfied with phlebotomy. Deferasirox treatment or phlebotomy reduces iron burden in pediatric patients with β- thalassemia major post-HSCT, with a manageable safety profile. © 2016 Wiley Periodicals, Inc.

    Issues of academic integrity, specifically knowledge of, perceptions and attitudes toward plagiarism, are well documented in post-secondary settings using case studies for specific courses, recording discourse with focus groups, analyzing cross-cultural education philosophies, and reviewing the current literature. In this paper, the authors examine the perceptions of graduate students in science, technology, engineering, and mathematics (STEM) disciplines at the University of Florida regarding misconduct and integrity issues. Results revealed students' perceptions of the definition and seriousness of potential academic misconduct, knowledge of institutional procedures, and views on faculty actions, all with a focus on divergences between U.S. and internationally-educated students. The open-ended questions provide anecdotal evidence to highlight personal experiences, positive and negative, aimed at the faculty, international students and undergraduates. Combined, these findings outline an important part of the campus academic integrity culture at a major American university. Recommendations for local actions also are discussed.

    Allogeneic mesenchymal stem cells (MSCs) are a promising cell source for treating musculoskeletal injuries in horses. Effective and safe allogeneic therapy may be hindered, however, by recipient immune recognition and rejection of major histocompatibility complex (MHC)-mismatched MSCs. Development of strategies to prevent immune rejection of MHC-mismatched MSCs in vivo is necessary to enhance cell survival and potentially increase the efficacy and safety of allogeneic MSC therapy. The purposes of this study were to evaluate if transforming growth factor-β2 (TGF-β2) downregulated MHC expression on equine MSCs and to determine if TGF-β2 treatment altered the phenotype of MSCs. Equine bone marrow-derived MSCs from 12 horses were treated with 1, 5, or 10 ng/ml TGF-β2 from initial isolation until MHC expression analysis. TGF-β2-treated MSCs had reduced MHC I and MHC II surface expression compared to untreated controls. TGF-β2 treatment also partially blocked IFN-γ-induced upregulation of MHC I and MHC II. Constitutive and IFN-γ-induced MHC I and MHC II expression on equine MSCs was dynamic and highly variable, and the effect of TGF-β2 was significantly dependent on the donor animal and baseline MHC expression. TGF-β2 treatment did not appear to change morphology, surface marker expression, MSC viability, or secretion of TGF-β1, but did significantly increase the number of cells obtained from culture. These results indicate that TGF-β2 treatment has promise for regulating MHC expression on MSCs to facilitate allogeneic therapy, but further work is needed to maintain MHC stability when exposed to an inflammatory stimulus.

  15. Perceived Mathematical Ability under Challenge: A Longitudinal Perspective on Sex Segregation among STEM Degree Fields

    2015-06-01

    Full Text Available Students’ perceptions of their mathematics ability vary by gender and seem to influence science, technology, engineering, and math (STEM degree choice. Related, students’ perceptions during academic difficulty are increasingly studied in educational psychology, suggesting a link between such perceptions and task persistence. Despite interest in examining the gender disparities in STEM, these concepts have not been considered in tandem. We investigate how perceived ability under challenge – in particular in mathematics domains – influences entry into the most sex-segregated and mathematics-intensive undergraduate degrees: physics, engineering, mathematics, and computer science (PEMC. Using nationally representative Education Longitudinal Study of 2002 (ELS data, we estimate the influence of perceived ability under challenging conditions on advanced high school science course taking, selection of an intended STEM major, and specific major type two years after high school. Demonstrating the importance of specificity when discussing how gender influences STEM career pathways, the intersecting effects of gender and perceived ability under mathematics challenge were distinct for each scientific major category. Perceived ability under challenge in secondary school varied by gender, and was highly predictive of selecting PEMC and health sciences majors. Notably, women’s 12th grade perceptions of their ability under mathematics challenge increased the probability that they would select PEMC majors, increasing women's probability of selecting PEMC over and above biology. In addition, gender moderated the effect of growth mindset on students’ selection of health science majors. The implications of these results are discussed, with particular attention to access to advanced scientific coursework in high school and interventions aimed at enhancing young women’s perceptions of their ability to facilitate their pathways to scientific degrees.

    Several studies have demonstrated that undergraduate students benefit from research experiences. Benefits of undergraduate research include 1) personal and intellectual development, 2) more and closer contact with faculty, 3) the use of active learning techniques, 4) creation of high expectations, 5) development of creative and problem-solving skills, 6) greater independence and intrinsic motivation to learn, and 7) exposure to practical skills. The scientific discipline also benefits, as studies have shown that undergraduates who engage in research experiences are more likely to remain science majors and finish their degree program (Lopatto, 2007). Research experiences come as close as possible to allowing undergraduates to experience what it is like to be an academic or research member of their profession working to advance their discipline. Soils form in the field, therefore, field experiences are very important in developing a complete and holistic understanding of soil science. Combining undergraduate research with field experiences can provide extremely beneficial outcomes to the undergraduate student, including increased understanding of and appreciation for detailed descriptions and data analysis as well as an enhanced ability to see how various parts of their undergraduate education come together to understand a complex problem. The experiences of the authors in working with undergraduate students on field-based research projects will be discussed, along with examples of some of the undergraduate research projects that have been undertaken. In addition, student impressions of their research experiences will be presented. Reference Lopatto, D. 2007. Undergraduate research experiences support science career decisions and active learning.

    NOAA supports about 115 - 150 undergraduates per year through the Ernest F. Hollings Scholarship and the Educational Partnership Program Undergraduate Scholarship. These programs provide tuition support and paid summer internships at NOAA to exceptional students majoring in the geosciences. Multiple methods were used to evaluate program outcomes and track the career trajectories, including mining LinkedIn data and conducting evaluation surveys of recipients as well as students who applied but did not receive the award. Results show more than 75% of scholars continued on to graduate school, primarily in a NOAA mission fields. This compared to only 56% of nonrecipients. More than 60% of alumni had at least one professional record, with the most alumni working in private industry, followed by nongovernmental organizations and federal, state and local government. The evaluation identified 77 other scholarship programs applied to by NOAA scholarship recipients. The most commonly reported program was the NSF Research Experiences for Undergraduates (REU) for which 20% of scholars applied and 46% of applications were successful. Other common scholarships included the Goldwater Scholarship (received by 5% of NOAA scholars) and the Udall Scholarship (received by 4% of scholars). In the most recent class of 118 undergraduate scholars, 24% reported having another research experience by the time they arrived for orientation at the end of their sophomore year. These results suggest coordination across scholarship opportunities may be useful to engage and retain students in geoscience fields.

    Watershed Watch (NSF 0525433) engages early undergraduate students from two-year and four-year colleges in student-driven full inquiry-based instruction in the biogeosciences. Program goals for Watershed Watch are to test if inquiry-rich student-driven projects sufficiently engage undeclared students (or noncommittal STEM majors) to declare a STEM major (or remain with their STEM major). A significant component of this program is an intensive two-week Summer course, in which undeclared freshmen research various aspects of a local watershed. Students develop their own research questions and study design, collect and analyze data, and produce a scientific or an oral poster presentation. The course objectives, curriculum and schedule are presented as a model for dissemination for other institutions and programs seeking to develop inquiry-rich courses designed to attract students into biogeoscience disciplines. Data from self-reported student feedback indicated the most important factors explaining high-levels of student motivation and research excellence in the course are 1) working with committed, energetic, and enthusiastic faculty mentors; and 2) faculty mentors demonstrating high degrees of teamwork and coordination.

    During the last seven years Michigan State University has been able to increase the number of physics and astrophysics majors by more than a factor of two. Part of this increase can be attributed to introducing special first-year courses on computational physics and on laboratory techniques, designed exclusively for physics majors. Investing into strengthening the Society of Physics Students and Science Theatre and into increased outreach activities also plays a role. But the largest effect is due to integrating a wide variety of research experiences into the Michigan State undergraduate physics and astrophysics experience. An overview of these activities will be given, and ways to upscale these efforts will be discussed.

    The impact of undergraduate neuroscience programs on the broader landscape of life sciences education has not been described. Using data from the National Center for Education Statistics, we found that the number of undergraduate neuroscience programs in the U.S. continues to grow. Within any given institution, neuroscience programs exist alongside a small number of other life sciences undergraduate programs, suggesting that neuroscience is one of few major options from which students can choose from at many institutions. Neuroscience majors constitute a substantial proportion of all life sciences graduates at many institutions, and in several cases, neuroscience majors were the majority of life sciences graduates. Thus, neuroscience programs contribute substantially to life sciences education, and neuroscience is a highly attractive major among undergraduate students where these programs are available. These data have implications for institutions with existing neuroscience programs as well as for institutions seeking to establish a new program.

  7. Explaining the Gender Gap: Comparing Undergraduate and Graduate/Faculty Beliefs about Talent Required for Success in Academic Fields

    Science.gov (United States)

    Bailey, Kimberlyn; Nanthakumar, Ampalavanar; Preston, Scott; Ilie, Carolina C.

    Recent research has proposed that the gender gap in academia is caused by differing perceptions of how much talent is needed to succeed in various fields. It was found that, across the STEM/non-STEM divide, the more that graduate students and faculty see success in their own field as requiring as requiring talent, the fewer women participate in that field. This research examines whether undergraduate students share these attitudes. If these attitudes trickle down to the undergraduate population to influence students to choose different fields of study, then undergraduate beliefs should reflect those of graduate students and faculty. Using a large survey of undergraduates across the country, this study aims to characterize undergraduate attitudes and to determine variables that explain the differences between the attitudes of these two populations. Our findings suggest that the two populations have similar beliefs, but that undergraduate beliefs are strongly influenced by information about the gender ratio in each field and that this strong influence greatly differs between STEM and non-STEM fields. These findings seek to help direct future research to ask the right questions and propose plausible hypotheses about gender the imbalance in academia.

    ABSTRACT The state of science, technology, engineering and math (STEM) education in the United States has seen some unfavorable assessments over the past decade. In early February, 2010 the House of Representatives heard testimony on undergraduate and graduate education. The message from the panel, which included experts from academia, STEM-based industries, and the National Science Foundation (NSF) was dire and required an urgent response. The experts along with the committee's chairperson, U. S. Representative Daniel Lipinski (D-IL) cited that the complexity of Science, Technology, Engineering, and Mathematics applications and coursework and the methodology utilized to teach these subjects are forcing students out of these disciplines. As the National Academies described in its 2007 report Rising Above the Gathering Storm, successful STEM education is not just an academic pursuit it's a necessity for competing in the knowledge-based economy that the United States had a key role in creating. The potential for action is being made available again as the America COMPETES Act of 2007 is up for reauthorization. Its initial focus was on STEM education at the K-12 levels, but efforts at the undergraduate and graduate levels are needed to retain students to fill the jobs left vacant as baby boomers retire. The Educational Advancement Alliance, Inc. (EAA) has for two decades created programs that have not only addressed the issues of ensuring that students are aptly prepared for college but have focused its efforts over the past decade on increasing the number of students who pursue degrees in STEM disciplines. For the EAA, the introduction of the wonders of science begins at the elementary and middle school level via the Learning Lab, a state-of-the-art mobile science laboratory that visits students in grades 4-6 at the various schools throughout Philadelphia and The Math/Tech Academy which meets on Saturdays for students in grades 5-7. For the past two years

  9. Cognitive diversity in undergraduate engineering: Dyslexia

    Science.gov (United States)

    Fitzpatrick, Velvet R.

    In the United States, institutions have established multiple programs and initiatives aimed at increasing the diversity of both faculty and students in engineering as means to produce a workforce that will better serve society. However, there are two major problems in addressing engineering student diversity. First, the engineering education research community has paid little attention to date as to how engineering education research characterizes diversity in its broadest sense. Second, research on persons with disabilities in undergraduates engineering, a population of interests within diversity, is minimal. Available disability studies tend to be skewed toward physical disabilities, leading to a neglect of cognitive differences such as learning disabilities (LD). In addition, disability research questions and study designs are inherently steeped in ability bias. The purpose of this dissertation is to explore the meaning of ability for students with dyslexia while in undergraduate engineering and establish the significance of cognitive diversity, focusing on LD and more specifically dyslexia, in undergraduate engineering education and answer the following research question: How do undergraduate engineering students with dyslexia experience ability while pursuing and persisting in engineering? The motivation was to lay the groundwork for future engineering education studies on undergraduate students with LD in general but dyslexia in specific. The first goal was to conduct a critical literature review pertaining to the academic strengths of undergraduate students with LD, specifically, dyslexia and the second goal was to describe how undergraduate engineering students with dyslexia experience ability. The intent was not to redefine dyslexia or disability. The intent is to provide an inclusive account of dyslexia, weakness and strengths, within the field of engineering education. This study was conducted from a qualitative inquiry approach, within the social

    2007-11-01

    Undergraduate research experiences have motivated many physics majors to continue their studies at the graduate level. The Department of Physics and Astronomy at SUNY Geneseo, a primarily undergraduate institution, recognizes this simple reality and is committed to ensuring research opportunities are available to interested majors beginning as early as their freshman year. Every year for more than a decade, as many as two dozen students and 8 faculty members have worked on projects related to high energy density physics and inertial confinement fusion during the summer months and the academic year. By working with their research sponsors, it has been possible to identify an impressive number of projects suitable for an institution such as Geneseo. These projects tend to be hands-on and require teamwork and innovation to be successful. They also take advantage of in-house capabilities such as the 2 MV tandem pelletron accelerator, a scanning electron microscope, a duoplasmatron ion deposition system and a 64 processor computing cluster. The end products of their efforts are utilized at the sponsoring facilities in support of nationally recognized programs. In this talk, I will discuss a number of these projects and point out what made them attractive and appropriate for an institution like Geneseo, the direct and indirect benefits of the research opportunities for the students and faculty, and how the national programs benefited from the cost-effective use of undergraduate research. In addition, I will discuss the importance of exposure for both students and faculty mentors to the larger scientific community through posters presentations at annual meetings such as the DPP and DNP. Finally, I will address the need for even greater research opportunities for undergraduate students in the future and the importance of establishing longer ``educational pipelines'' to satisfy the ever growing need for top-tier scientists and engineers in industry, academia and the

    2016-01-01

    Matrix groups touch an enormous spectrum of the mathematical arena. This textbook brings them into the undergraduate curriculum. It makes an excellent one-semester course for students familiar with linear and abstract algebra and prepares them for a graduate course on Lie groups. Matrix Groups for Undergraduates is concrete and example-driven, with geometric motivation and rigorous proofs. The story begins and ends with the rotations of a globe. In between, the author combines rigor and intuition to describe the basic objects of Lie theory: Lie algebras, matrix exponentiation, Lie brackets, maximal tori, homogeneous spaces, and roots. This second edition includes two new chapters that allow for an easier transition to the general theory of Lie groups. From reviews of the First Edition: This book could be used as an excellent textbook for a one semester course at university and it will prepare students for a graduate course on Lie groups, Lie algebras, etc. … The book combines an intuitive style of writing w...

  18. A theoretical lens on a biology intensive orientation program: A study of self-efficacy and self-regulation of freshman biology majors

    Science.gov (United States)

    Wheeler, Erin R.

    There is a national effort to increase the number of undergraduate students graduating in science, math, engineering, and technology (STEM) (National Science Foundation, 2007). The majority of students initially populating these STEM majors ultimately switch to and graduate from non-STEM majors (Seymour & Hewitt, 2000; Seymour, 2002). The source of attrition from STEM fields lies within the difficulty of concepts presented in freshman STEM introductory courses (Jensen & Moore, 2007, 2008, 2009; Seymour & Hewitt, 2000). These gateway courses are considered high-risk because nearly half of students enrolled in these courses receive either a "D" or "F" or completely withdraw from the course (Labov, 2004). Research shows that students who have uncalibrated self-efficacy and an attenuated self-regulated learning are unsuccessful in high-risk courses (Kitsantas et al., 2008; Ross, Green, Salisbury-Glennon, & Tollefson, 2006; Zimmerman, 2002). Traditional academic assistance, such as tutoring, learning to learn courses, and supplemental instruction, does not explicitly develop an undergraduate's self-efficacy and self-regulated learning as it specifically relates to the STEM domains (Cao & Nietfeld, 2007; Dembo & Seli, 2006; Ross et al., 2006; Simpson, Hind, Nist, Burrell, 1997). Some STEM departments have created academic interventions, such as one-credit seminars, orientation programs, and bridge programs, to directly address the needs of STEM majors (Belzer, 2003; Bonner, 2009; Chevalier, Chrisman, & Kelsey, 2001; Hutchison-Green, Follman, & Bodner, 2008; D. J. Minchella, Yazvac, C. W., Fodrea, R. A., Ball G., 2007; Reyes, Anderson-Rowland, & McCartney, 1998). This study focused on the effect of a biology-intensive orientation program on biology majors' self-efficacy and self-regulated learning. The study utilized approximately 300 undergraduate biology majors participating in a biology-intensive orientation that occurred on August 7-12, 2011, at a public state

    2017-12-01

    Multidisciplinary undergraduate climate change education is critical for students entering any sector of the workforce. The University of Delaware has developed a new interdisciplinary affinity program—UD Climate Program for Undergraduates (CPUG)—open to undergraduate students of all majors to provide a comprehensive educational experience designed to educate skilled climate change problem-solvers for a wide range of professional careers. The program is designed to fulfill all General Education requirements, and includes a residential community commitment and experiential learning in community outreach and problem solving. Seminars will introduce current popular press and research materials and provide practice in confirming source credibility, communications training, and psychological support, as well as team building. As undergraduates, members of the UD CPUG team will define, describe, and develop a solution or solutions for a pressing local climate challenge that has the potential for global impact. The choice of a challenge and approach to addressing it will be guided by the student's advisor. Students are expected to develop a practical, multidisciplinary solution to address the challenge as defined, using their educational and experiential training. Solutions will be presented to the UD community during the spring semester of their senior year, as a collaborative team solution, with enhancement through individual portfolios from each team member. The logic model, structure, curricular and co-curricular supports for the CPUG will be provided. Mechanisms of support available through University administration will also be discussed.

    Undergraduate students majoring in forestry generally reflect that genetics is one of the most difficult compul-sory courses, because the traditional teaching method is difficult to satisfy their needs. According to the theoretical charac-teristics of forestry and actual demands of the students, in the light of teaching and research experience in recent years, we adopted a series of typical genetic cases such as 'opening coffin to identify relatives', stem-throne of Lycium ruthenicum Murr, and magic powers in Harry Potter. Our practices revealed that the case teaching in genetics could train good personality traits, learning abilities and creativity of the students, stimulate their interests and initiatives in learning, and increase systematic learning.

  6. Undergraduate medical research: the student perspective

    Directory of Open Access Journals (Sweden)

    Louise N. Burgoyne

    2010-09-01

    Full Text Available Background: Research training is essential in a modern undergraduate medical curriculum. Our evaluation aimed to (a gauge students’ awareness of research activities, (b compare students’ perceptions of their transferable and research-specific skills competencies, (c determine students’ motivation for research and (d obtain students’ personal views on doing research. Methods: Undergraduate medical students (N=317 completed a research skills questionnaire developed by the Centre for Excellence in Teaching and Learning in Applied Undergraduate Research Skills (CETL-AURS at Reading University. The questionnaire assessed students’ transferable skills, research-specific skills (e.g., study design, data collection and data analysis, research experience and attitude and motivation towards doing research. Results: The majority of students are motivated to pursue research. Graduate entrants and male students appear to be the most confident regarding their research skills competencies. Although all students recognise the role of research in medical practice, many are unaware of the medical research activities or successes within their university. Of those who report no interest in a career incorporating research, a common perception was that researchers are isolated from patients and clinical practice. Discussion: Students have a narrow definition of research and what it entails. An explanation for why research competence does not align more closely with research motivation is derived from students’ lack of understanding of the concept of translational research, as well as a lack of awareness of the research activity being undertaken by their teachers and mentors. We plan to address this with specific research awareness initiatives.

    2017-01-01

    The NSF-sponsored Undergraduate ALFALFA (Arecibo Legacy Fast ALFA) Team (UAT) is a consortium of 20 institutions across the US and Puerto Rico, founded to promote undergraduate research and faculty development within the extragalactic ALFALFA HI blind survey project and follow-up programs. The objective of the UAT is to provide opportunities for its members to develop expertise in the technical aspects of observational radio spectroscopy, its associated data analysis, and the motivating science. Partnering with Arecibo Observatory, the UAT has worked with more than 280 undergraduates and 26 faculty to date, offering 8 workshops onsite at Arecibo (148 undergraduates), observing runs at Arecibo (69 undergraduates), remote observing runs on campus, undergraduate research projects based on Arecibo science (120 academic year and 185 summer projects), and presentation of results at national meetings such as the AAS (at AAS229: Ball et al., Collova et al., Davis et al., Miazzo et al., Ruvolo et al, Singer et al., Cannon et al., Craig et al., Koopmann et al., O'Donoghue et al.). 40% of the students and 45% of the faculty participants have been women and members of underrepresented groups. More than 90% of student alumni are attending graduate school and/or pursuing a career in STEM. 42% of those pursuing graduate degrees in Physics or Astronomy are women.In this presentation, we summarize the UAT program and the current research efforts of UAT members based on Arecibo science, including multiwavelength followup observations of ALFALFA sources, the UAT Collaborative Groups Project, the Survey of HI in Extremely Low-mass Dwarfs (SHIELD), and the Arecibo Pisces-Perseus Supercluster Survey (APPSS).

  10. Providing Real Research Opoportunities to Undergraduates

    Science.gov (United States)

    Ragozzine, Darin

    2016-01-01

    The current approach to undergraduate education focuses on teaching classes which provide the foundational knowledge for more applied experiences such as scientific research. Like most programs, Florida Institute of Technology (Florida Tech or FIT) strongly encourages undergraduate research, but is dominated by content-focused courses (e.g., "Physical Mechanics"). Research-like experiences are generally offered through "lab" classes, but these are almost always reproductions of past experiments: contrived, formulaic, and lacking the "heart" of real (i.e., potentially publishable) scientific research. Real research opportunities 1) provide students with realistic insight into the actual scientific process; 2) excite students far more than end-of-chapter problems; 3) provide context for the importance of learning math, physics, and astrophysics concepts; and 4) allow unique research progress for well-chosen problems. I have provided real research opportunities as an "Exoplanet Lab" component of my Introduction to Space Science (SPS1020) class at Florida Tech, generally taken by first-year majors in our Physics, Astronomy & Astrophysics, Planetary Science, and Astrobiology degree programs. These labs are a hybrid between citizen science (e.g., PlanetHunters) and simultaneously mentoring ~60 undergraduates in similar small research projects. These projects focus on problems that can be understood in the context of the course, but which benefit from "crowdsourcing". Examples include: dividing up the known planetary systems and developing a classification scheme and organizing them into populations (Fall 2013); searching through folded light curves to discover new exoplanets missed by previous pipelines (Fall 2014); and fitting n-body models to all exoplanets with known Transit Timing Variations to estimate planet masses (Fall 2015). The students love the fact that they are doing real potentially publishable research: not many undergraduates can claim to have discovered

  11. Undergraduate paramedic students cannot do drug calculations

    Science.gov (United States)

    Eastwood, Kathryn; Boyle, Malcolm J; Williams, Brett

    2012-01-01

    BACKGROUND: Previous investigation of drug calculation skills of qualified paramedics has highlighted poor mathematical ability with no published studies having been undertaken on undergraduate paramedics. There are three major error classifications. Conceptual errors involve an inability to formulate an equation from information given, arithmetical errors involve an inability to operate a given equation, and finally computation errors are simple errors of addition, subtraction, division and multiplication. The objective of this study was to determine if undergraduate paramedics at a large Australia university could accurately perform common drug calculations and basic mathematical equations normally required in the workplace. METHODS: A cross-sectional study methodology using a paper-based questionnaire was administered to undergraduate paramedic students to collect demographical data, student attitudes regarding their drug calculation performance, and answers to a series of basic mathematical and drug calculation questions. Ethics approval was granted. RESULTS: The mean score of correct answers was 39.5% with one student scoring 100%, 3.3% of students (n=3) scoring greater than 90%, and 63% (n=58) scoring 50% or less, despite 62% (n=57) of the students stating they ‘did not have any drug calculations issues’. On average those who completed a minimum of year 12 Specialist Maths achieved scores over 50%. Conceptual errors made up 48.5%, arithmetical 31.1% and computational 17.4%. CONCLUSIONS: This study suggests undergraduate paramedics have deficiencies in performing accurate calculations, with conceptual errors indicating a fundamental lack of mathematical understanding. The results suggest an unacceptable level of mathematical competence to practice safely in the unpredictable prehospital environment. PMID:25215067

  12. Measuring Science Literacy in College Undergraduates

    2010-01-01

    Initial results from a major study of scientific literacy are presented, involving nearly 10,000 undergraduates in science classes at a large Southwestern Land Grant public university over a 20-year period. The science content questions overlap with those in the NSF's Science Indicators series. About 10% of all undergraduates in the US take a General Education astronomy course, and NSF data and the work of Jon Miller show that the number of college science courses taken is the strongest predictor of civic scientific literacy. Our data show that gains in knowledge on any particular item through the time students graduate are only 10-15%. Among students who have taken most or all of their science requirements, one-in-three think that antibiotics kill viruses as well as bacteria, one-in-four think lasers work by focusing sound waves, one-in-five think atoms are smaller than electrons, and the same fraction is unaware that humans evolved from earlier species of animals and that the Earth takes a year to go around the Sun. The fraction of undergraduates saying that astrology is "not at all” scientific increases from 17% to a still-low 34% as they move through the university. Equally worrying, half of all science majors say that astrology is "sort of” or "very” scientific. Education majors - the cohort of future teachers - perform worse than average on most individual questions and in terms of their overall scientific literacy. Assuming the study institution is representative of the nation's higher education institutions, our instruction is not raising students to the level we would expect for educated citizens who must vote on many issues that relate to science and technology. We acknowledge the NSF for funding under Award No. 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars (CATS) Program.

    2011-03-01

    Undergraduate research is a valuable educational tool for students pursuing a degree in physics, but these experiences can become problematic and ineffective if not handled properly. Undergraduate research should be planned as an immersive learning experience in which the student has the opportunity to develop his/her skills in accordance with their interests. Effective undergraduate research experiences are marked by clear, measurable objectives and frequent student-professor collaboration. These objectives should reflect the long and short-term goals of the individual undergraduates, with a heightened focus on developing research skills for future use. 1.

    2004-07-01

    Full Text Available Abstract Fueled by the promise of regenerative medicine, currently there is unprecedented interest in stem cells. Furthermore, there have been revolutionary, but somewhat controversial, advances in our understanding of stem cell biology. Stem cells likely play key roles in the repair of diverse lung injuries. However, due to very low rates of cellular proliferation in vivo in the normal steady state, cellular and architectural complexity of the respiratory tract, and the lack of an intensive research effort, lung stem cells remain poorly understood compared to those in other major organ systems. In the present review, we concisely explore the conceptual framework of stem cell biology and recent advances pertinent to the lungs. We illustrate lung diseases in which manipulation of stem cells may be physiologically significant and highlight the challenges facing stem cell-related therapy in the lung.

    Christensen, Rhonda; Knezek, Gerald; Tyler-Wood, Tandra

    2015-12-01

    This study examines positive dispositions reported by middle school and high school students participating in programs that feature STEM-related activities. Middle school students participating in school-to-home hands-on energy monitoring activities are compared to middle school and high school students in a different project taking part in activities such as an after-school robotics program. Both groups are compared and contrasted with a third group of high school students admitted at the eleventh grade to an academy of mathematics and science. All students were assessed using the same science, technology, engineering and mathematics (STEM) dispositions instrument. Findings indicate that the after-school group whose participants self-selected STEM engagement activities, and the self-selected academy of mathematics and science group, each had highly positive STEM dispositions comparable to those of STEM professionals, while a subset of the middle school whole-classroom energy monitoring group that reported high interest in STEM as a career, also possessed highly positive STEM dispositions comparable to the STEM Professionals group. The authors conclude that several different kinds of hands-on STEM engagement activities are likely to foster or maintain positive STEM dispositions at the middle school and high school levels, and that these highly positive levels of dispositions can be viewed as a target toward which projects seeking to interest mainstream secondary students in STEM majors in college and STEM careers, can hope to aspire. Gender findings regarding STEM dispositions are also reported for these groups.

    The NSF-funded GEodesy Tools for Societal Issues (GETSI) project is developing teaching resources for use in introductory and majors-level courses, emphasizing a broad range of geodetic methods and data applied to societally important issues. The modules include a variety of hands-on activities, demonstrations, animations, and interactive online tools in order to facilitate student learning and engagement. A selection of these activities will be showcased at the AGU session. These activities and data analysis exercises are embedded in 4-6 units per module. Modules can take 2-3 weeks of course time total or individual units and activities can be selected and used over just 1-2 class periods. Existing modules are available online via serc.carleton.edu/getsi/ and include "Ice mass and sea level changes", "Imaging active tectonics with LiDAR and InSAR", "Measuring water resources with GPS, gravity, and traditional methods", "Surface process hazards", and "GPS, strain, and earthquakes". Modules, and their activities and demonstrations were designed by teams of faculty and content experts and underwent rigorous classroom testing and review using the process developed by the Science Education Resource Center's InTeGrate Project (serc.carleton.edu/integrate). All modules are aligned to Earth Science and Climate literacy principles. GETSI collaborating institutions are UNAVCO (which runs NSF's Geodetic Facility), Indiana University, and Mt San Antonio College. Initial funding came from NSF's TUES (Transforming Undergraduate Education in STEM). A second phase of funding from NSF IUSE (Improving Undergraduate STEM Education) is just starting and will fund another six modules (including their demonstrations, activities, and hands-on activities) as well as considerably more instructor professional development to facilitate implementation and use.

    Women still remain underrepresented in many areas of the geosciences, and this underrepresentation often begins early in their university career. In 2015, an interdisciplinary team including expertise in the geosciences (multiple sub-disciplines), psychology, education and STEM persistence began a project focused on understanding whether mentoring can increase the interest, persistence, and achievement of undergraduate women in geoscience fields. The developed program (PROGRESS) focuses on mentoring undergraduate female students, starting in their 1st and 2nd year, from two geographically disparate areas of the United States: the Carolinas in the southeastern part of the United States and the Front Range of the Rocky Mountains in the western part of the United States. The two regions were chosen due to their different student demographics, as well as the differences in the number of working female geoscientists in the region. The mentoring program includes a weekend workshop, access to professional women across geoscience fields, and both in-person and virtual peer networks. Four cohorts of students were recruited and participated in our professional development workshops (88 participants in Fall 2015 and 94 participants in Fall 2016). Components of the workshops included perceptions of the geosciences, women in STEM misconceptions, identifying personal strengths, coping strategies, and skills on building their own personal network. The web-platform (http://geosciencewomen.org/), designed to enable peer-mentoring and provide resources, was launched in the fall of 2015 and is used by both cohorts in conjunction with social media platforms. We will present an overview of the major components of the program, discuss lessons learned during 2015 that were applied to 2016, and share preliminary analyses of surveys and interviews with study participants from the first two years of a five-year longitudinal study that follows PROGRESS participants and a control group.

    Einstein’s special and general theories of relativity are explored graphically and quantitatively using elementary algebra through a series of fifteen interactive lectures designed for undergraduate physics majors.  Topics covered include:  space-time diagrams, special relativity, the equivalence principle, general relativity, and black holes.  The goal of this book is to provide the student with a sound, conceptual understanding of both the special and the general theories of relativity, so the student will gain insight into how astrophysicists are using these theories to study black holes in the universe.  At the end of each chapter, there is a set of exercises to further facilitate the student’s understanding of the material. The ultimate goal of the book is for students to continue to use it as a preferred reference during and after their undergraduate career.

    One aspect of assessing the undergraduate curriculum is recognizing that the exit vector of the student is a metric in the absence of a structured assessment program. Detailed knowledge across all geosciences departments regarding the disposition of their recent baccalaureate recipients has been at best inconsistent, and in the case of about half of geoscience programs, non-existent. However, through examining of multiple datasets, a pattern of disposition of geosciences BS recipients emerges, providing a snapshot of the system- wide response to the system-wide "average" program. This pattern can also be juxtaposed against several frameworks of desired skill sets for recent graduates and the employment sectors likely to hire them. The question remains is can one deduce the effectiveness of the undergraduate program in placing graduates in their next step, whether in graduate school or the workplace. Likewise, with an increasing scrutiny on the "value" of an education, is the resulting economic gain sufficient for the student, such that programs will be viewed as sustainable. A factor in answering this question is the importance of the undergraduate program in the ultimate destination of the professional. Clear pathways exist for "optimal" schools for the production of new faculty and new industry professionals, but is it possible to identify those trends further up the educational pipeline? One major mechanism to examine the undergraduate program effectiveness related to exit vectors is to look at hiring trends witnessed related to markedly different program structures, such as those at universities outside of the United States. Rectifying academic programs between the United States and other national systems is often a challenge, but even given the substantial differences between depth of technical knowledge and breadth of education across these programs, in the end, the sum product is often viewed as roughly comparable. This paper will look at end

    There is a proliferation of medical devices across the globe for the diagnosis and therapy of diseases. Biomedical engineering (BME) plays a significant role in healthcare and advancing medical technologies thus creating a substantial demand for biomedical engineers at undergraduate and graduate levels. There has been a surge in undergraduate programs due to increasing demands from the biomedical industries to cover many of their segments from bench to bedside. With the requirement of multidisciplinary training within allottable duration, it is indeed a challenge to design a comprehensive standardized undergraduate BME program to suit the needs of educators across the globe. This paper's objective is to describe three major models of undergraduate BME programs and their curricular requirements, with relevant recommendations to be applicable in institutions of higher education located in varied resource settings. Model 1 is based on programs to be offered in large research-intensive universities with multiple focus areas. The focus areas depend on the institution's research expertise and training mission. Model 2 has basic segments similar to those of Model 1, but the focus areas are limited due to resource constraints. In this model, co-op/internship in hospitals or medical companies is included which prepares the graduates for the work place. In Model 3, students are trained to earn an Associate Degree in the initial two years and they are trained for two more years to be BME's or BME Technologists. This model is well suited for the resource-poor countries. All three models must be designed to meet applicable accreditation requirements. The challenges in designing undergraduate BME programs include manpower, facility and funding resource requirements and time constraints. Each academic institution has to carefully analyze its short term and long term requirements. In conclusion, three models for BME programs are described based on large universities, colleges, and

    There is a dearth of mental health research on undergraduates in Sri Lanka. This study examines the prevalence of depression in a sample of Sri Lankan undergraduates, their exposure to threatening life events and the predictors of their depression. Responses of 4304 undergraduates were obtained on the Patient Health Questionnaire-9 and a measure of exposure to threatening life events, with binary logistic regression models used to identify the demographic and life event correlates of screening positive for Major Depressive Disorder (MDD). PHQ-9 diagnoses of 'Major' and 'Other' depression were obtained by 9.3% and 13.5% of undergraduates, respectively. A higher likelihood of MDD was seen among those who were older and those living in hostels (compared to home), although no differences were seen between genders or those studying in different faculties. Likelihood of MDD was higher in undergraduates exposed to multiple threatening life events as well as those exposed to physical threat; family deaths; romantic break-ups; a problem with a close associate; educational difficulties; unemployment and domestic violence, and among male undergraduates harassed by another student. MDD is prevalent in these undergraduates and universities need to develop services to assist them. Such services may also need to focus on supporting those who have experienced threatening life events, particularly those that arise as a result of being an undergraduate, as these may increase the risk of MDD.

    Business, industry, parks, nature settings, government infrastructure, and people, can be invaluable resources for connecting STEM curriculum within context which results in conditions ideal for promoting purposeful learning of authentic STEM content. Thus, community-based STEM resources offer ideal context for teaching STEM content. A benefit of focusing teacher attention on these contextual, content aligned resources is that they are in every community; making place-based STEM education a possibility, regardless of the location of STEM teaching and learning. Further, associating STEM teaching and learning with local resources addresses workforce development and the STEM pipeline by exposing students to STEM careers and applications in their local communities. The desire to align STEM teaching and learning with local STEM related resources guided the design of our week-long integrated STEM K-12 teacher professional development (PD) program, i-STEM. We have completed four years of our i-STEM PD program and have made place-based STEM a major emphasis of our curriculum. This report focuses on the data collected in the fourth year of our program. Our week-long i-STEM PD served over 425 educators last summer (2013), providing them with in depth theme-based integrated STEM short courses which were limited to an average of 15 participants and whole group plenary sessions focused around placed based integrated STEM, inquiry, engineering design, standards and practices of Common Core and 21st Century skills. This state wide PD was distributed in five Idaho community colleges and took place over two weeks. The STEM short courses included topics on engineering for sustainability, using engineering to spark interest in STEM, municipal water systems, health, agriculture, food safety, mining, forestry, energy, and others. Integral to these short courses were field trips designed to connect the K-12 educators to the resources in their local communities that could be leveraged

    Pressures from students and teachers, from professional bodies, and from changes in the way health care is delivered are all forcing a rethink of how medical students should be taught. These pressures may be more intense in London but are not confined to it. The recommendation the Tomlinson report advocates that has been generally welcomed is for more investment in primary care in London. General practitioners have much to teach medical schools about effective ways of learning, but incentives for teaching students in general practice are currently low, organising such teaching is difficult and needs resources, and resistance within traditional medical school hierarchies needs to be overcome. Likewise, students value learning within local communities, but the effort demanded of public health departments and community organisations is great at a time when they are under greater pressure than ever before. The arguments over research that favour concentration in four multifaculty schools are less clear cut for undergraduate education, where personal support for students is important. An immediate concern is that the effort demanded for reorganising along the lines suggested by Tomlinson will not leave medical schools much energy for innovating.

  20. Collaborative, Early-undergraduate-focused REU Programs at Savannah State University have been Vital to Growing a Demographically Diverse Ocean Science Community

    Formal support for undergraduates to participate in marine/ocean science research at Savannah State University (SSU), a historically-Black unit of the University System of Georgia, began in 1989 with funding from the National Science Foundation for an unsolicited proposal (OCE-8919102, 34,935). Today SSU, which has offered B.S degrees since 1979 and M.S. degrees since 2001 in Marine Sciences, is making major contributions nationally to demographic diversity in ocean sciences. 33% of Master's degrees in marine/ocean sciences earned by African Americans in the U.S. from 2004-2007 were earned at SSU. 10% of African American Master's and Doctoral students in marine/ ocean sciences in 2007 were either enrolled in the Master's program at SSU or were former SSU students enrolled in Doctoral programs elsewhere. Collaborative REU programs that focus on early (freshman and sophomore) undergraduate students have been a consistent and vital part of that success. In the most recent iteration of our summer REU program we used six of the best practices outlined in the literature to increase success and retention of underrepresented minority students in STEM fields: early intervention, strong mentoring, research experience, career counseling, financial support, workshops and seminars. The early intervention with strong mentoring has proven successful in several metrics: retention in STEM majors (96%), progression to graduate school (50%), and continuation to later research experiences (75%). Research mentors include faculty at staff at SSU, the Skidaway Institute of Oceanography, Gray's Reef National Marine Sanctuary and Georgia Tech-Savannah. Formal collaborative and cooperative agreements, externally-funded grants, and contracts in support of student research training have proven to be critical in providing resources for growth and improvement marine science curricular options at the University. Since 1981 the program has had four formal partnerships and 36 funded grant awards

    This study attempts to understand whether medical undergraduates in Sri Lanka would seek help for depression. This was done by examining their perceptions and intentions relating to seeking help for depression, using the responses of non-medical undergraduates as the baseline for comparison. Medical (n = 620) and non-medical undergraduates (n = 4050) at the University of Colombo responded to a questionnaire which included a vignette about a depressed undergraduate, a depression measure, an open-ended question examining their intentions to seek help if affected by the problem described in the vignette, and scales examining their perceptions about the helpfulness of various help-seeking options for dealing with the problem. The latter items were also administered among mental health professionals to assess expert opinion on dealing with depression. Logistic regression models were used to examine if medical undergraduates differed from non-medical undergraduates in their rates of depression, help-seeking perceptions and help-seeking intentions. These models were also used to examine if being depressed was associated with differences in the help-seeking perceptions and intentions of medical undergraduates. Medical and non-medical undergraduates did not differ in their odds of being depressed. Overall, the medical undergraduates were more likely to appraise professional help positively. However, they did not differ from non-medical undergraduates in relation to their intentions to seek such help if affected by the problem personally. They were also more likely to indicate their intentions to seek help from parents and family. Furthermore, medical undergraduates who screened positive for Major Depression were less likely to appraise some of the recommended professional and informal help-seeking options as being 'helpful', with only 50 % considering that it was 'unhelpful' to deal with the problem alone. There was also no difference in their help

    Stem/progenitor cell-based therapeutic approach in clinical practice has been an elusive dream in medical sciences, and improvement of stem cell homing is one of major challenges in cell therapy programs. Stem/progenitor cells have a homing response to injured tissues/organs, mediated by interactions of chemokine receptors expressed on the cells and chemokines secreted by the injured tissue. For improvement of directed homing of the cells, many techniques have been developed either to engineer stem/progenitor cells with higher amount of chemokine receptors (stem cell-based strategies) or to modulate the target tissues to release higher level of the corresponding chemokines (target tissue-based strategies). This review discusses both of these strategies involved in the improvement of stem cell homing focusing on mesenchymal stem cells as most frequent studied model in cellular therapies. © 2014 International Federation for Cell Biology.

    Physical inactivity is a common risk factor for several non-communicable diseases (NCDs). Increasing physical activity could reduce the burden of disease due to major NCDs and increase life expectancy. Undergraduate physiotherapy students represent a group of young-adults expected to have a good knowledge of physical activity. We evaluated physical activity levels of undergraduate physiotherapy students of University of Colombo, Sri Lanka and determined their motives and barriers for participation in physical activity. All physiotherapy undergraduates studying at the University of Colombo, Sri Lanka in 2013 were invited for the study. Phase one was a quantitative study to evaluate the physical activity levels and phase two was a qualitative study to identify motives and barriers for physical activity and sports in the same cohort. Physical activity levels (phase 1) were assessed using the interviewer administered International Physical Activity Questionnaire (long-version). The qualitative study (phase 2) was conducted in the same population using Focus Group Discussions ( n  = 3) and individual In-depth Interviews ( n  = 5). Sample size in phase 1 and phase 2 were 113 (response rate = 98%; [N-115]) and 87 (response rat = 97%; [N-90]) respectively. Mean age (±SD) of participants was 23.4 ± 1 years. The mean weekly total MET minutes (±SD) of the study population was 1791.25 ± 3097. According to the IPAQ categorical score a higher percentage of participants were 'inactive' (48.7%), while only 15.9% were in the 'Highly active' group. Lack of support and encouragement received during childhood to engage in sports activity seem to have played an important role in continuing their exercise behavior through to the adult life. Academic activities were given priority by both parents and teachers. The environment and support from teachers, family and friends were important to initiate and adhere to sports and physical activity. A higher

    Life science professional societies play important roles for undergraduates in their fields and increasingly offer membership, fellowships, and awards for undergraduate students. However, the overall impacts of society-student interactions have not been well studied. Here, we sought to develop and test a pilot survey of undergraduate students to determine how they got involved in research and in presenting at the Experimental Biology (EB) meeting, what they gained from the scientific and career development sessions at the meeting, and how the American Physiological Society (APS) can best support and engage undergraduate students. This survey was administered in 2014 and 2015 to undergraduate students who submitted physiology abstracts for and attended EB. More than 150 students responded (38% response rate). Respondents were demographically representative of undergraduate students majoring in life sciences in the United States. Most students (72%) became involved in research through a summer research program or college course. They attended a variety of EB sessions, including poster sessions and symposia, and found them useful. Undergraduate students interacted with established researchers at multiple venues. Students recommended that APS provide more research fellowships (25%) and keep in touch with students via both e-mail (46%) and social media (37%). Our results indicate that APS' EB undergraduate activities are valued by students and are effective in helping them have a positive scientific meeting experience. These results also guided the development of a more streamlined survey for use in future years. Copyright © 2017 the American Physiological Society.

    The vertebrate eye is fantastically sensitive instrument, capable of registering the absorption of a single photon, and yet generating very low noise.Using eyes as a common thread helps motivate undergraduates to learn a lot of physics, both fundamental and applied to scientific imaging and neuroscience. I'll describe an undergraduate course, for students in several science and engineering majors, that takes students from the rudiments of probability theory to the quantum character of light, including modern experimental methods like fluorescence imaging and Förster resonance energy transfer. After a digression into color vision, we then see how the Feynman principle explains the apparently wavelike phenomena associated to light, including applications like diffraction, subdiffraction imaging, total internal reflection and TIRF microscopy. Then we see how scientists documented the single-quantum sensitivity of the eye seven decades earlier than `ought' to have been possible, and finally close with the remarkable signaling cascade that delivers such outstanding performance.Course materials are available upon request.

    2009-12-01

    Watershed Watch (NSF 0525433) engages early undergraduate students from two-year and four-year colleges in student-driven full inquiry-based instruction in the biogeosciences. Program goals for Watershed Watch are to test if inquiry-rich student-driven projects sufficiently engage undeclared students (or noncommittal STEM majors) to declare a STEM major (or remain with their STEM major). The program is a partnership between two four-year campuses - the University of New Hampshire (UNH), and Elizabeth City State University (ECSU, in North Carolina); and two two-year campuses - Great Bay Community College (GBCC, in New Hampshire) and the College of the Albemarle (COA, in North Carolina). The program focuses on two watersheds: the Merrimack Ricer Watershed in New Hampshire and Massachusetts, and the Pasquotank River Watershed in Virginia and North Carolina. Both the terrestrial and aquatic components of both watersheds are evaluated using the student-driven projects. A significant component of this program is an intensive two-week Summer Research Institute (SRI), in which undeclared freshmen and sophomores investigate various aspects of their local watershed. Two Summer Research Institutes have been held on the UNH campus (2006 and 2008) and two on the ECSU campus (2007 and 2009). Students develop their own research questions and study design, collect and analyze data, and produce a scientific oral or poster presentation on the last day of the SRI. The course objectives, curriculum and schedule are presented as a model for dissemination for other institutions and programs seeking to develop inquiry-rich programs or courses designed to attract students into biogeoscience disciplines. Data from self-reported student feedback indicate the most important factors explaining high-levels of student motivation and research excellence in the program are: 1) working with committed, energetic, and enthusiastic faculty mentors, and 2) faculty mentors demonstrating high degrees of

    2017-01-01

    Full Text Available As a unique and versatile undergraduate degree program, a Bachelor of Science in Pharmaceutical Sciences (BSPS is offered by a number of colleges/schools of pharmacy. These provide a bachelor's degree concentrated in pharmaceutical sciences, and can be a non-Doctor of Pharmacy option, possibly before progressing to graduate degree studies. Recently implemented at the University of Toledo College of Pharmacy and Pharmaceutical Sciences (UTCPPS, one such BSPS major is Cosmetic Science and Formulation Design. This new undergraduate major was created to serve the needs of the cosmetic and personal care industry, with a great need identified for well-trained new professionals with basic knowledge in the sciences and business. This Cosmetic Science and Formulation Design major was added to four other BSPS majors at UTCPPS. Introduced in 2013, this major is the only functioning undergraduate degree in Cosmetic Science and Formulation Design in the United States. Preliminary job placement data provides promising evidence that this undergraduate major has helped graduates launch a career in the cosmetic and personal care, or pharmaceutical industries. Based on our experience from the past three years, we believe that this cosmetic science major has been worth its resource investment. We hope others designing new undergraduate pharmaceutical sciences programs might integrate advice from this experience into their impending programs.   Type: Idea Paper

    2012-02-01

    BACKGROUND: International experience has demonstrated that the medical profession is becoming less dominated by men. This "feminization of medicine" has been a topic of much debate in the medical literature. As the gender ratio in the profession changes, it is likely that a greater proportion of undergraduate education will be provided by women. Whether this shift away from the male-dominated provision of medical education will have an effect on undergraduate education is unknown. PURPOSE: The aim of this research was to clarify whether there are differences between the attitudes and practices of male and female junior doctors regarding the practice of undergraduate teaching. METHOD: A survey methodology among a cohort of nonconsultant hospital doctors in a major Irish teaching hospital was utilized. The overall response rate was 93%. The cohort held a positive attitude toward teaching undergraduates, and the majority were actively engaged in this activity. Doctors of both genders expressed a willingness to undertake teacher training. RESULTS: There were no significant differences between the genders regarding the self-reported quantity of teaching provided to undergraduates. Male doctors perceived themselves as more confident educators when compared to female doctors, but this is likely to reflect cohort demographics in which a greater proportion of male doctors were more senior. CONCLUSIONS: This study demonstrates that male and female doctors have similar attitudes toward, and practices in, voluntary undergraduate teaching. As a result, any gender shift in medicine is unlikely to result in a significant change in junior doctors\\' attitudes toward undergraduate medical education.

    Programs launched by many universities and the federal government expose many undergraduate students in the physical sciences to research early in their careers. However, in their research experiences, undergraduates are not usually introduced to the modes by which scientific knowledge, which they may have helped gather, is communicated and evaluated by working scientists. Nor is it always made clear where the research frontiers really lie. To this end, we guided a selected group of undergraduates through a national scientific conference, followed by a week of tutorials and discussions to help them better understand what had transpired. The program complemented the basic undergraduate research endeavors by emphasizing the importance of disseminating results both to other scientists and to society in general. Tutors and discussion leaders in the second week were experts in their fields and included some of the invited speakers from the main meeting. A considerable improvement in the understanding of the issues and prospects for a career in physics was discernible among the students after their two-week experience. copyright 1999 American Association of Physics Teachers

    2015-04-01

    A high percentage of non-science majors enroll in undergraduate, introductory astronomy courses across the country. The perception of the astronomy course as being easier than the ``hard sciences'' and the idea that the course will focus on ``pretty pictures'', influences the interests of the non-science majors. Often the students that enroll in these courses will not take other science courses, resulting in the only opportunity to teach college students about basic scientific concepts that impact their lives. Vast misconceptions about the nature of science, the role of science and scientists in society, and social issues embedded in scientific information, impact the decisions that individuals make about every day events. In turn, these decisions influence the policies that construct our society. This talk will provide an overview of the common misconceptions and discuss how they impact our society as a whole. The research presented provides evidence of the impact that introductory college astronomy courses have on changing these everyday misconceptions and influencing non-science majors' ideas about science in society. The research suggests that introductory courses designed for non-science majors are extremely important in impacting our society, and begs for a stronger understanding and implementation of best practices for teaching and learning in the college classroom environment.

    Several models have been explored at Indiana University Bloomington for undergraduate student engagement in astronomy using the WIYN 0.9-m telescope at Kitt Peak. These models include individual student research projects using the telescope, student observations as part of an observational techniques course for majors, and enrichment activities for non-science majors in general education courses. Where possible, we arrange for students to travel to the telescope. More often, we are able to use simple online tools such as Skype and VNC viewers to give students an authentic observing experience. Experiences with the telescope motivate students to learn basic content in astronomy, including the celestial sphere, the electromagnetic spectrum, telescopes and detectors, the variety of astronomical objects, date reduction processes, image analysis, and color image creation and appreciation. The WIYN 0.9-m telescope is an essential tool for our program at all levels of undergraduate education

    2016-01-01

    The Bologna Process model of higher education has been introduced into some Australian universities since 2008. This model promoted university study through a liberal arts philosophy that advanced a worldview approach at the undergraduate level. The model generalized the student experience and eliminated undergraduate specialization. An interesting situation for music undergraduate study thus arose. Expertise and expert performance research has argued an opposing educational approach, namely: Extensive long-term commitment through focused practical engagement and specialized tuition as prerequisites to achieving musical mastery, especially in performance. Motivation research has shown that the majority of this specialized development in pre-university years would be accessed and reinforced predominantly through private music tuition. Drawing on this contextual literature, commencing university music undergraduates would have expectations of their prospective study founded from two historical influences. The first: How undergraduates had accessed pre-university music tuition. The second: How and in what ways undergraduates' pre-university musical activities were experienced and reinforced. Using usefulness and importance measures, the study observed the expectations of students about to commence music undergraduate studies at three representative Australian university music schools. One of these universities operated the Bologna styled model. No other known Australian study has investigated this implementation for any effects upon music undergraduate expectations. How much commencing music undergraduates would draw on their pre-university music instruction and experiences to predict their usefulness and importance expectations formed the basis for this investigation.

    Academic ethical awareness is an important aspect especially for nursing students who will provide ethical nursing care to patients in future or try to tread the path of learning toward professional acknowledgement in nursing scholarship. The purpose of this study was to explore academic ethical awareness and its related characteristics among undergraduate nursing students. This study commenced the survey with cross-sectional, descriptive questions and enrolled convenient samples of 581 undergraduate nursing students from three universities in South Korea. It was investigated with structured questionnaires including general characteristics and academic ethical awareness related. Ethical considerations: This study was reviewed and approved by the Institutional Review Board at National University. Academic ethical awareness was the highest regarding behaviors violating the respect or confidentiality of patients and cheating on exams, while it was the lowest for inappropriate behaviors in class. From the result of general characteristics difference, male students showed higher score than female students in relative; first-year students showed higher score than other year students; the higher score was rated from students who were highly satisfied with their major than the other not satisfied with their major; and students with low academic stress showed higher ethical awareness score than persons with higher stress. Personal behaviors were rated with low ethical awareness in relative, but items related to public rules and actual effects on patients or others were rated with higher score. Nursing satisfaction and academic stress are main factors on ethical awareness. To improve overall ethical awareness level of nursing students, it is required to provide more education about the importance of personal behaviors in class and need to improve the understanding of how it will be connected with future situation and effect.

    Despite knowledge on the molecular basis of amyotrophic lateral sclerosis (ALS) having quickly progressed over the last few years, such discoveries have not yet translated into new therapeutics. With the advancement of stem cell technologies there is hope for stem cell therapeutics as novel treatments for ALS. We discuss in detail the therapeutic potential of different types of stem cells in preclinical and clinical works. Moreover, we address many open questions in clinical translation. SC therapy is a potentially promising new treatment for ALS and the need to better understand how to develop cell-based experimental treatments, and how to implement them in clinical trials, becomes more pressing. Mesenchymal stem cells and neural fetal stem cells have emerged as safe and potentially effective cell types, but there is a need to carry out appropriately designed experimental studies to verify their long-term safety and possibly efficacy. Moreover, the cost-benefit analysis of the results must take into account the quality of life of the patients as a major end point. It is our opinion that a multicenter international clinical program aime d at fine-tuning and coordinating transplantation procedures and protocols is mandatory.

    Matz, Rebecca L.; Jardeleza, Sarah E.

    2016-01-01

    Undergraduate science, technology, engineering, and mathematics (STEM) education reform continues to be a national priority. We studied a reform process in undergraduate biology at a research-intensive university to explore what leadership issues arose in implementation of the initiative when characterized with a descriptive case study method. The data were drawn from transcripts of meetings that occurred over the first 2 years of the reform process. Two literature-based models of change were used as lenses through which to view the data. We find that easing the burden of an undergraduate education reform initiative on faculty through articulating clear outcomes, developing shared vision across stakeholders on how to achieve those outcomes, providing appropriate reward systems, and ensuring faculty have ample opportunity to influence the initiative all appear to increase the success of reform. The two literature-based models were assessed, and an extended model of change is presented that moves from change in STEM instructional strategies to STEM organizational change strategies. These lessons may be transferable to other institutions engaging in education reform. PMID:27856545

    Tissue engineering and regenerative medicine have been constantly developing of late due to the major progress in cell and organ transplantation, as well as advances in materials science and engineering. Although stem cells hold great potential for the treatment of many injuries and degenerative diseases, several obstacles must be overcome before their therapeutic application can be realized. These include the development of advanced techniques to understand and control functions of micro environmental signals and novel methods to track and guide transplanted stem cells. A major complication encountered with stem cell therapies has been the failure of injected cells to engraft to target tissues. The application of nanotechnology to stem cell biology would be able to address those challenges. Combinations of stem cell therapy and nanotechnology in tissue engineering and regenerative medicine have achieved significant advances. These combinations allow nanotechnology to engineer scaffolds with various features to control stem cell fate decisions. Fabrication of Nano fiber cell scaffolds onto which stem cells can adhere and spread, forming a niche-like microenvironment which can guide stem cells to proceed to heal damaged tissues. In this paper, current and emergent approach based on stem cells in the field of liver tissue engineering is presented for specific application. The combination of stem cells and tissue engineering opens new perspectives in tissue regeneration for stem cell therapy because of the potential to control stem cell behavior with the physical and chemical characteristics of the engineered scaffold environment.

    2008-01-01

    Paralleling the explosive growth of neuroscientific knowledge over the last two decades, numerous institutions from liberal arts colleges to research universities have either implemented or begun exploring the possibility of implementing undergraduate programs in neuroscience. In 1995, Faculty for Undergraduate Neuroscience (FUN) partnered with Project Kaleidoscope (PKAL) to offer a workshop exploring how undergraduate neuroscience education should proceed. Four blueprints were created to provide direction to the burgeoning interest in developing programs in undergraduate neuroscience education: 1) Neuroscience nested in psychology; 2) Neuroscience nested in biology; 3) Neuroscience as a minor; and 4) Neuroscience as a major. In 2005, FUN again partnered with PKAL to revisit the blueprints in order to align the blueprints with modern pedagogical philosophy and technology. The original four blueprints were modified and updated. One particularly exciting outgrowth of the 2005 workshop was the introduction of a fifth curricular blueprint that strongly emphasizes the integration of the humanities and social sciences into neuroscience: Neuroscience Studies. Because of the interdisciplinary nature of neuroscience, an education in neuroscience will prepare the next generation of students to think critically, synthetically, and creatively as they confront the problems facing humanity in the 21(st) century.

    Maintaining a reliable pool of qualified nuclear engineering graduates depends on the ability of nuclear engineering undergraduate programs to recruit students. With the prospect of declining enrollments in nuclear engineering it is important for nuclear engineering programs to know what factors influence students to choose nuclear engineering as an undergraduate major and why they choose a particular undergraduate program. This type of information can be very important to nuclear engineering programs that develop recruiting strategies. To provide some insight into this area, a questionnaire was designed and given to undergraduate nuclear engineering students at Pennsylvania State University. The purpose of the survey was to provide information on the reasons that students picked nuclear engineering as a career and chose to attend Penn State. The questionnaire was given to 27 students in their junior year during the spring semester of 1987 and again to 35 junior students during the spring semester of 1988. There was little difference except as noted between the two groups on their responses to the questionnaire. A partial listing of the survey results is provided

    Blended learning is a combination of online and face-to-face learning and is increasingly of interest for use in undergraduate medical education. It has been used to teach clinical post-graduate students pharmacology but needs evaluation for its use in teaching pharmacology to undergraduate medical students, which represent a different group of students with different learning needs. An existing BSc-level module on neuropharmacology was redesigned using the Blended Learning Design Tool (BLEnDT), a tool which uses learning domains (psychomotor, cognitive and affective) to classify learning outcomes into those taught best by self-directed learning (online) or by collaborative learning (face-to-face). Two online courses were developed, one on Neurotransmitters and the other on Neurodegenerative Conditions. These were supported with face-to-face tutorials. Undergraduate students' engagement with blended learning was explored by the means of three focus groups, the data from which were analysed thematically. Five major themes emerged from the data 1) Purpose and Acceptability 2) Structure, Focus and Consolidation 3) Preparation and workload 4) Engagement with e-learning component 5) Future Medical Education. Blended learning was acceptable and of interest to undergraduate students learning this subject. They expressed a desire for more blended learning in their courses, but only if it was highly structured, of high quality and supported by tutorials. Students identified that the 'blend' was beneficial rather than purely online learning.

    Background The introduction of ultrasound into the undergraduate medical school curriculum is gaining momentum in North America. At present, many institutions are teaching ultrasound to undergraduate medical students using a traditional framework designed to instruct practicing clinicians, or have modeled the curriculum on other universities. This approach is not based on educational needs or supported by evidence. Methods Using a descriptive, cross-sectional survey of stakeholder groups, we assessed the perceived relevance of various ultrasound skills and the attitude towards implementing an undergraduate ultrasound curriculum at our university. Results One hundred and fifty survey respondents representing all major stakeholder groups participated. All medical students, 97% of residents and 82% of educators agreed that the introduction of an ultrasound curriculum would enhance medical students' understanding of anatomy and physiology. All clinical medical students and residents, 92% of preclinical medical students, and 82% of educators agreed that the curriculum should also include clinical applications of ultrasound. Participants also indicated their preferences for specific curriculum content based on their perceived needs. Conclusion An integrated undergraduate ultrasound curriculum composed of specific preclinical and clinical applications was deemed appropriate for our university following a comprehensive needs assessment. Other universities planning such curricula should consider employing a needs assessment to provide direction for curriculum need and content.

    Twenty years ago I attended my very first AAS meeting as a 21-year old undergraduate physics major. At that meeting I presented the light curve of a variable star I had studied as part of a mentored research program at BYU. That opportunity to do mentored research, and to attend a professional meeting of astronomers, helped to set the foundation for my success today as an associate professor of physics and astronomy. Twenty years ago I was the student, now I am the mentor! I have eight undergraduate students whom I currently supervise in active research, four of which are presenting their senior projects at the 225th meeting of the AAS.My experience has shown me that the full impact of mentored research cannot be measured by yearly numbers or statistics. When we mentor a student, we influence their career path and choices for years to come. Where feasible, every undergraduate should have the opportunity to do research if they so choose. It is a sacrifice of our time and our effort that cannot be easily measured through numbers or results, and is only visible many years down the road as these students become the future leaders in astronomy and policy. In this poster, I will discuss the benefits of mentored research, the growth we have seen at BYU over the past twenty years with the introduction of a mentored research program, and ideas for implementing mentored research and writing into course curricula to enhance the undergraduate educational experience.

    Stereotypes associating men and masculine traits with science, technology, engineering, and mathematics (STEM) fields are ubiquitous, but the relative strength of these stereotypes varies considerably across cultures. The present research applies an intersectional approach to understanding ethnic variation in gender-STEM stereotypes and STEM participation within an American university context. African American college women participated in STEM majors at higher rates than European American college women (Study 1, Study 2, and Study 4). Furthermore, African American women had weaker implicit gender-STEM stereotypes than European American women (Studies 2-4), and ethnic differences in implicit gender-STEM stereotypes partially mediated ethnic differences in STEM participation (Study 2 and Study 4). Although African American men had weaker implicit gender-STEM stereotypes than European American men (Study 4), ethnic differences between men in STEM participation were generally small (Study 1) or nonsignificant (Study 4). We discuss the implications of an intersectional approach for understanding the relationship between gender and STEM participation. (c) 2015 APA, all rights reserved).

    In 2007, the Department of Natural Resources and Environmental Science established the first undergraduate degree in Ecohydrology in the United States. The degree was designed to prepare students for careers as hydrologists while also including coursework equivalent to a minor in ecology (UNR does not officially offer a minor in ecology). The development of the major was intended to provide students with useful skills and training for the job market, and also to increase enrollment in the University's water-related undergraduate majors. The Department also established an Ecohydrology minor. Since the degree was established, average enrollment in the major has been almost two times higher than the previous Watershed Science option in Environmental Science (the closest comparable degree offering at UNR). The Department has graduated 19 students as of May 2014, and an additional 8 students have graduated with the Ecohydrology minor. Several Ecohydrology graduates have gone on to graduate degrees, and most of the remainder are employed in water-related areas. The students have established an Ecohydrology Club at UNR and are active in organizing water-related activities to do together. This presentation will describe the development of the degree, its implementation, and challenges and opportunities for carrying out an undergraduate degree in Ecohydrology. It will also discuss potential development of a 5-year Bachelor of Science-Master of Science (BS-MS) degree in Ecohydrology.

  7. Predicting College Readiness in STEM: A Longitudinal Study of Iowa Students

    Science.gov (United States)

    Rickels, Heather Anne

    The demand for STEM college graduates is increasing. However, recent studies show there are not enough STEM majors to fulfill this need. This deficiency can be partially attributed to a gender discrepancy in the number of female STEM graduates and to the high rate of attrition of STEM majors. As STEM attrition has been associated with students being unprepared for STEM coursework, it is important to understand how STEM graduates change in achievement levels from middle school through high school and to have accurate readiness indicators for first-year STEM coursework. This study aimed to address these issues by comparing the achievement growth of STEM majors to non-STEM majors by gender in Science, Math, and Reading from Grade 6 to Grade 11 through latent growth models (LGMs). Then STEM Readiness Benchmarks were established in Science and Math on the Iowas (IAs) for typical first-year STEM courses and validity evidence was provided for the benchmarks. Results from the LGM analyses indicated that STEM graduates start at higher achievement levels in Grade 6 and maintain higher achievement levels through Grade 11 in all subjects. In addition, gender differences were examined. The findings indicate that students with high achievement levels self-select as STEM majors, regardless of gender. In addition, they suggest that students who are not on-track for a STEM degree may need to begin remediation prior to high school. Results from the benchmark analyses indicate that STEM coursework is more demanding and that students need to be better prepared academically in science and math if planning to pursue a STEM degree. In addition, the STEM Readiness Benchmarks were more accurate in predicting success in STEM courses than if general college readiness benchmarks were utilized. Also, students who met the STEM Readiness Benchmarks were more likely to graduate with a STEM degree. This study provides valuable information on STEM readiness to students, educators, and college

  8. An Approach to Integrating Health Disparities within Undergraduate Biomedical Engineering Education.

    2017-11-01

    Health disparities are preventable differences in the incidence, prevalence and burden of disease among communities targeted by gender, geographic location, ethnicity and/or socio-economic status. While biomedical research has identified partial origin(s) of divergent burden and impact of disease, the innovation needed to eradicate health disparities in the United States requires unique engagement from biomedical engineers. Increasing awareness of the prevalence and consequences of health disparities is particularly attractive to today's undergraduates, who have undauntedly challenged paradigms believed to foster inequality. Here, the Department of Biomedical Engineering at The City College of New York (CCNY) has leveraged its historical mission of access-and-excellence to integrate the study of health disparities into undergraduate BME curricula. This article describes our novel approach in a multiyear study that: (i) Integrated health disparities modules at all levels of the required undergraduate BME curriculum; (ii) Developed opportunities to include impacts of health disparities into undergraduate BME research projects and mentored High School summer STEM training; and (iii) Established health disparities-based challenges as BME capstone design and/or independent entrepreneurship projects. Results illustrate the rising awareness of health disparities among the youngest BMEs-to-be, as well as abundant undergraduate desire to integrate health disparities within BME education and training.

    Steane, Andrew M

    2016-01-01

    This is an undergraduate textbook in thermodynamics—the science of heat, work, temperature, and entropy. The text presents thermodynamics in and of itself, as an elegant and powerful set of ideas and methods. These methods open the way to understanding a very wide range of phenomena in physics, chemistry, engineering, and biology. Starting out from an introduction of concepts at first year undergraduate level, the roles of temperature, internal energy, and entropy are explained via the laws of thermodynamics. The text employs a combination of examples, exercises, and careful discussion, with a view to conveying the feel of the subject as well as avoiding common misunderstandings. The Feynman–Smuluchowski ratchet, Szilard’s engine, and Maxwell’s daemon are used to elucidate entropy and the second law. Free energy and thermodynamic potentials are discussed at length, with applications to solids as well as fluids and flow processes. Thermal radiation is discussed, and the main ideas significant to global...

    Peer assisted learning (PAL) has been shown in undergraduate programmes to be as effective as learning from instructors. PAL is a shared experience between two learners often with one being more senior to the other but usually both are studying within the same discipline. Interprofessional education occurs when two or more professionals learn with, from and about each other. Benefits of PAL in an interprofessional context have not been previously explored. As part of a final year education unit, midwifery students at Monash University developed workshops for second year undergraduate paramedic students. The workshops focused on care required during and after the birth of the baby. To investigate the benefits of an interprofessional PAL for both midwifery and paramedic students. Data for this project were obtained by both quantitative and qualitative methods. Questionnaires were distributed to both cohorts of students to explore experiences of peer teaching and learning. Results were analysed using Statistical Package for Social Sciences (SPSS). Focus groups were conducted separately with both cohorts of students and transcripts analysed using a thematic approach. Response rates from the midwifery and paramedic students were 64.9% and 44.0% respectively. The majority of students regardless of discipline enjoyed the interprofessional activity and wanted more opportunities in their curricula. After initial anxieties about teaching into another discipline, 97.3 (n = 36) of midwifery students thought the experience was worthwhile and personally rewarding. Of the paramedic students, 76.9% (n = 60) reported enjoying the interaction. The focus groups supported and added to the quantitative findings. Both midwifery and paramedic students had a new-found respect and understanding for each other's disciplines. Midwifery students were unaware of the limited knowledge paramedics had around childbirth. Paramedic students admired the depth of knowledge displayed by the midwifery

    The practice of travelling abroad to receive unproven and unregulated stem cell treatments has become an increasingly problematic global phenomenon known as 'stem cell tourism'. In this paper, we examine representations of nine major clinics and providers of such treatments on the microblogging network Twitter. We collected and conducted a content analysis of Twitter posts (n = 363) by these establishments and by other users mentioning them, focusing specifically on marketing claims about treatment procedures and outcomes, discussions of safety and efficacy of stem cell transplants, and specific representations of patients' experiences. Our analysis has shown that there were explicit claims or suggestions of benefits associated with unproven stem cell treatments in approximately one third of the tweets and that patients' experiences, whenever referenced, were presented as invariably positive and as testimonials about the efficacy of stem cell transplants. Furthermore, the results indicated that the tone of most tweets (60.2 %) was overwhelmingly positive and there were rarely critical discussions about significant health risks associated with unproven stem cell therapies. When placed in the context of past research on the problems associated with the marketing of unproven stem cell therapies, this analysis of representations on Twitter suggests that discussions in social media have also remained largely uncritical of the stem cell tourism phenomenon, with inaccurate representations of risks and benefits for patients.

    Research examining the depression literacy of undergraduates in non-western developing countries is limited. This study explores this among undergraduates in Sri Lanka. A total of 4671 undergraduates responded to a survey presenting a vignette of a depressed undergraduate. They were asked to identify the problem, describe their intended help-seeking actions if affected by it and rate the helpfulness of a range of help-providers and interventions for dealing with it. Mental health experts also rated these options, providing a benchmark for assessing the undergraduates' responses. Only 17.4% of undergraduates recognised depression, but this was significantly lower among those responding in Sinhala compared to English (3.5 vs 36.8%). More undergraduates indicated intentions of seeking informal help, such as from friends and parents, than from professionals, such as psychiatrists and counsellors. However, a majority rated all these help-providers as 'helpful', aligning with expert opinion. Other options recommended by experts and rated as 'helpful' by a large proportion of undergraduates included counselling/psychological therapy and self-help strategies such as doing enjoyable activities and meditation/yoga/relaxation exercises. However, a low proportion of undergraduates rated "western medicine to improve mood" as 'helpful', deviating from expert opinion. Although not endorsed by experts, undergraduates indicated intentions of using religious strategies, highly endorsing these as 'helpful'. Labelling the problem as depression and using mental health-related labels were both associated with higher odds of endorsing professional help, with the label 'depression' associated with endorsing a wider range of professional options. The recognition rate of depression might be associated with the language used to label it. These undergraduates' knowledge about the use of medication for depression needs improvement.

    According to American Institute of Physics statistics the College of Charleston's Department of Physics and Astronomy is second among all primarily undergraduate institutions in the production of physics and astronomy bachelor's degrees. A little over a decade ago the roster faculty of the department consisted of 5 physicists and 2 astronomers. Currently we have 13 filled positions including 6 astronomers and are hiring 3 additional faculty this year. What has caused this growth? While there are a number of factors, our undergraduate research program is a major one. Although we have required a "senior project" for 30 years about 15 years ago we started encouraging students to present their work at both a college wide research poster session and the annual meeting of the South Carolina Academy of Science. We also began to encourage students to begin research earlier in their careers. At about the same time we received NSF funding to operate an automatic photometric telescope in southern Arizona. This facility greatly increased the opportunities available in astronomy. A decade ago venues for student presentations were expanded to include AAS meetings as well as others. Undergraduate students, especially beginning ones, require very careful and time-consuming mentoring. In addition to funding from NSF our students have also been funded by the SC Space Grant and by internal funds. Even in the time of drastic budget cuts our president has begun funding 20 competitive summer research appointments for undergraduates as well as providing travel support for attendance at meetings. In summary, our emphasis on undergraduate research has attracted students and in turn resulted in the administration granting us additional faculty lines. The new faculty hires have been instrumental in attracting even more students. I would like to express my appreciation to my students and colleagues and to NSF for supporting our automatic telescope for the last 14 years under the following

    The SETI Institute and San Jose State University (SJSU) have begun a partnership (URSA: Undergraduate Research at the SETI Institute in Astrobiology) in which undergraduate science and engineering majors from SJSU participate in research at the SETI Institute during the academic year. We are currently in our second year of the three-year NASA-funded grant. The goal of this program is to expose future scientists, engineers and educators to the science of astrobiology and to NASA in general, and by so doing, to prepare them for the transition to their future career in the Silicon Valley or beyond. The URSA students are mentored by a SETI Institute scientist who conducts research at the SETI Institute headquarters or nearby at NASA Ames Research Center. The SETI Institute is a private, nonprofit organization dedicated to scientific research, education and public outreach. Its mission is to explore, understand and explain the origin, nature and prevalence of life in the universe. SJSU is a large urban public university that serves the greater Silicon Valley area in California. Students at SJSU come from diverse ethnic, cultural and socioeconomic backgrounds. Many of them face financial pressures that force them to pursue part-time work. URSA students are paid to work for 10 hours/week during the academic year, and also participate in monthly group meetings where they practice their presentation skills and discuss future plans. We encourage underserved and underrepresented students, including women, minority, and those who are the first in their family to go to college, to apply to the URSA program and provide ongoing mentoring and support as needed. While preparing students for graduate school is not a primary goal, some of our students have gone on to MS or PhD programs or plan to do so. The URSA program is funded by NASA EPOESS.

    Highly added sugar diets have been associated with various health problems such as dental caries, dyslipidemia, obesity and poor quality of life. Unfortunately, sugar consumption, especially sucrose, has increased continuously worldwide. The purpose of the study was to examine sources of sugar consumption and amount of added sucrose consumed in Thai undergraduate students. This study was carried out at Khon Kaen University, Thailand, between the years 2004-2005. A complete 3-day record of items and amounts of sweet consumption were obtained from 202 individuals--38 male and 164 female students. Added sucrose content of each sweetened food and drinks referred to in the record was determined by an enzymatic method. Mean intakes of sucrose were calculated from the sucrose content. The average of sucrose consumption in all subjects was 69+/-38 g/day, ranged from 4 to 182 g/day or 17 teaspoons of added sucrose per day. This amount accounted for 13.8% of total daily energy intake. There was a record of 337 kinds of sweetened foods and drinks found. The major source of added sucrose consumption was sweetened beverage, which was consumed 118 g/day averagely, or 60% of daily sugar consumption. Intake of sucrose per day in both male and female was not statistically difference, neither among different BMI groups. Intake of added sugar in the students was higher than the recommendation of the World Health Organization. These data would be helpful in a health promotion campaign aimed at a reduction of sugar consumption in Thai undergraduate students.

    While women's representation in higher education has increased at the undergraduate and graduate levels, female voices remain in the minority in upper administrative positions, particularly in STEM fields. The HERS Institutes prepare women faculty and administrators for leadership roles through either residential (2 week, summer) or mixed on-site and online (academic year) programs. Topics addressed through the HERS curriculum include managing and leading change, the financial environment of higher education, diversity and inclusion, career mapping, fundraising, the legal landscape, institutional budgeting, negotiation, search essentials, conflict management, and much more. Female experts in each field lead interactive sessions and discussions, and are available for one-on-one conversations during breaks and meals. Through a grant from the Henry Luce Foundation, HERS has created opportunities for women in STEM fields to receive scholarships to the Institutes through the Claire Booth Luce (CBL) Program. In addition, the Institutes now support a larger cohort of STEM participants through targeted programming and networking events. Of the 64 participants in the 2016 Bryn Mawr Institute, 21 women were from STEM fields. These women participated in additional programs and expert-led discussions including "The Future of Research in Higher Education," "Supporting Careers of Women in STEM," and "Inclusive Excellence in STEM." An additional component of the CBL Program is the creation of a HERS STEM Community to enhance networking, mentoring, information sharing, and opportunities for gathering at professional conferences among HERS alumnae.

  18. Music undergraduates' usefulness and importance expectations: The Bologna Process from an Australian university perspective

    Directory of Open Access Journals (Sweden)

    Dominic Harvey

    2016-07-01

    Full Text Available AbstractThe Bologna Process model of higher education has been introduced into some Australian universities since 2008. This model promoted university study through a liberal arts philosophy that advanced a worldview approach at the undergraduate level. The model generalised the student experience and eliminated undergraduate specialisation. An interesting situation for music undergraduate study thus arose. Expertise and expert performance research has argued an opposing educational approach, namely: Extensive long-term commitment through focused practical engagement and specialised tuition as prerequisites to achieving musical mastery, especially in performance. Motivation research has shown that the majority of this specialised development in pre-university years would be accessed and reinforced predominantly through private music tuition. Drawing on this contextual literature, commencing university music undergraduates would have expectations of their prospective study founded from two historical influences. The first: How undergraduates had accessed pre-university music tuition. The second: How and in what ways undergraduates’ pre-university musical activities were experienced and reinforced. Using usefulness and importance measures, the study observed the expectations of students about to commence music undergraduate studies at three representative Australian university music schools. One of these universities operated the Bologna styled model. No other known Australian study has investigated this implementation for any effects upon music undergraduate expectations. How much commencing music undergraduates would draw on their pre-university music instruction and experiences to predict their usefulness and importance expectations formed the basis for this investigation. Strong relationships between usefulness and importance were found across all units of study. Despite strong correlations across all units of study between usefulness and

    2013-12-01

    For the past five years, the New York City College of Technology has administered a successful National Science Foundation (NSF) Research Experience for Undergraduates (REU) program. The program provides rich, substantive, academic and life-transformative STEM educational experiences for students who would otherwise not pursue STEM education altogether or would not pursue STEM education through to the graduate school level. The REU Scholars are provided with an opportunity to conduct intensive satellite and ground-based remote sensing research at the National Oceanic and Atmospheric Administration Cooperative Remote Sensing Science and Technology Center (NOAA-CREST). Candidates for the program are recruited from the City University of New York's twenty-three separate campuses. These students engage in a research experience that spans the summer and the fall and spring semesters. Eighty-four percent (84%) of the program participants are underrepresented minorities in STEM, and they are involved in a plethora of undergraduate research best practice activities that include: training courses in MATLAB programming, Geographic Information Systems, and Remote Sensing; workshops in Research Ethics, Scientific Writing, and Oral and Poster Research Presentations; national, regional, and local conference presentations; graduate school support; and geoscience exposure events at national laboratories, agencies, and research facilities. To enhance their success in the program, the REU Scholars are also provided with a comprehensive series of safety nets that include a multi-tiered mentoring design specifically to address critical issues faced by this diverse population. Since the inception of the REU program in 2008, a total of 61 undergraduate students have finished or are continuing with their research or are pursuing their STEM endeavors. All the REU Scholars conducted individual satellite and ground-based remote sensing research projects that ranged from the study of

    2017-12-01

    The current structure of many undergraduate programs, particularly those at large research universities, requires students to engage with a major or academic emphasis early in their university careers. This oftentimes curbs exploration outside the major and can inhibit interdisciplinary collaboration. The Boston University Research Education and Communication of Science (BURECS) program seeks to bridge this institutional divide by fostering interdisciplinary and multidisciplinary collaboration on climate change-related issues by students from across Boston University (B.U.). Every year, approximately fifteen first-year students from B.U.'s College of Arts and Sciences, College of Communication, and School of Education are selected to join BURECS, which includes a climate science seminar, a hands-on lab course, a supported summer internship with Boston-area researchers, and the opportunity to participate in Antarctic field work during subsequent B.U. Antarctic Research Group expeditions. Currently in its third year, BURECS is funded through the Howard Hughes Medical Institute (HHMI) Professors Program.

    2016-12-01

    Canadian Indigenous people are an extremely poorly represented group in STEM today due to major barriers in obtaining a high school and then a university education. Approximately 10% of the undergraduate student population out of a total 12,600 students at the University of Regina, Regina, Saskatchewan, is First Nations, Métis or Inuit. The university is located in a catchment region where 30% of the population is First Nations or Métis. Approximately 100 students majoring in the sciences, mathematics and engineering have self-declared themselves to be Indigenous. For the past two years, we have been running a pilot project, the Initiative to Support and Increase the Number of Indigenous Students in the Sciences, Mathematics and Engineering at the Aboriginal Student Centre, with financial support from the Deans of Science and Engineering. We provide student networking lunches, Indigenous scientist and engineer speakers and mentors and supplemental tutoring. Our program is actively supported and guided by Elder Noel Starblanket, former president of the National Indian Brotherhood (now the Assembly of First Nations). Our students are greatly interested in the health and environmental sciences (particularly water quality), with a sprinkling of physics, mathematics and engineering majors. Our students have gone on to graduate work with prestigious scholarships and a paid internship in engineering. We report here on various lessons learned: the involvement of elders is key, as is the acceptance of non-traditional academic paths, and any STEM support program must respect Indigenous culture. There is great interest in science and engineering on the part of these students, if scientists and engineers are willing to listen and learn to talk with these students on their own terms.

  14. Stem cells and bone: a historical perspective.

    Science.gov (United States)

    Bianco, Paolo

    2015-01-01

    Bone physiology and stem cells were tightly intertwined with one another, both conceptually and experimentally, long before the current explosion of interest in stem cells and so-called regenerative medicine. Bone is home to the two best known and best characterized systems of postnatal stem cells, and it is the only organ in which two stem cells and their dependent lineages coordinate the overall adaptive responses of two major physiological systems. All along, the nature and the evolutionary significance of the interplay of bone and hematopoiesis have remained a major scientific challenge, but also allowed for some of the most spectacular developments in cell biology-based medicine, such as hematopoietic stem cell transplantation. This question recurs in novel forms at multiple turning points over time: today, it finds in the biology of the "niche" its popular phrasing. Entirely new avenues of investigation emerge as a new view of bone in physiology and medicine is progressively established. Looking at bone and stem cells in a historical perspective provides a unique case study to highlight the general evolution of science in biomedicine since the end of World War II to the present day. A paradigm shift in science and in its relation to society and policies occurred in the second half of the XXth century, with major implications thereof for health, industry, drug development, market and society. Current interest in stem cells in bone as in other fields is intertwined with that shift. New opportunities and also new challenges arise.

    2011-01-01

    Drosophila has long been an excellent model organism for studying stem cell biology. Notably, studies of Drosophila's germline stem cells have been instrumental in developing the stem cell niche concept. The recent discovery of somatic stem cells in adult Drosophila, particularly the intestinal stem cells (ISCs) of the midgut, has established Drosophila as an exciting model to study stem cell-mediated adult tissue homeostasis and regeneration. Here, we review the major signaling pathways that regulate the self-renewal, proliferation and differentiation of Drosophila ISCs, discussing how this regulation maintains midgut homeostasis and mediates regeneration of the intestinal epithelium after injury. -- Highlights: ► The homeostasis and regeneration of adult fly midguts are mediated by ISCs. ► Damaged enterocytes induce the proliferation of intestinal stem cells (ISC). ► EGFR and Jak/Stat signalings mediate compensatory ISC proliferation. ► Notch signaling regulates ISC self-renewal and differentiation.

    2012-12-01

    The U.S. remains in grave danger of losing its global competitive edge in STEM. To find solutions to this problem, the Obama Administration proposed two new national initiatives: the Educate to Innovate Initiative and the $100 million government/private industry initiative to train 100,000 STEM teachers and graduate 1 million additional STEM students over the next decade. To assist in ameliorating the national STEM plight, the New York City College of Technology has designed its NSF Research Experience for Undergraduate (REU) program in satellite and ground-based remote sensing to target underrepresented minority students. Since the inception of the program in 2008, a total of 45 undergraduate students of which 38 (84%) are considered underrepresented minorities in STEM have finished or are continuing with their research or are pursuing their STEM endeavors. The program is comprised of the three primary components. The first component, Structured Learning Environments: Preparation and Mentorship, provides the REU Scholars with the skill sets necessary for proficiency in satellite and ground-based remote sensing research. The students are offered mini-courses in Geographic Information Systems, MATLAB, and Remote Sensing. They also participate in workshops on the Ethics of Research. Each REU student is a member of a team that consists of faculty mentors, post doctorate/graduate students, and high school students. The second component, Student Support and Safety Nets, provides undergraduates a learning environment that supports them in becoming successful researchers. Special networking and Brown Bag sessions, and an annual picnic with research scientists are organized so that REU Scholars are provided with opportunities to expand their professional community. Graduate school support is provided by offering free Graduate Record Examination preparation courses and workshops on the graduate school application process. Additionally, students are supported by college

    2014-12-01

    PIRATE is a 0.43m semi-autonomous research and teaching observatory owned by The Open University, UK. Since 2010, it has been reserved for several months of each year for teaching astronomy in the OU's undergraduate programme. As students in these courses operate PIRATE remotely rather than travelling to the observatory itself, we chose to investigate whether effective learning was adversely affected by the absence of a more traditional `hands on' experience. We discuss student perspectives on the technologies employed (i.e., remote and virtual investigations), the impact these had on perceived course outcomes, and consider implications for future teaching and outreach.

    2015-01-01

    Aging affects endogenous stem cells in terms of functionality and numbers. In particular, during aging, the stemness property can decrease because of enhanced apoptotic cell death and senescence. In addition, aging and aging-related co-morbidities affect the paracrine activity of stem cells and the efficiency of their transplantation. Collectively, this leads to a reduction of the capacity of organs to repair themselves, possibly due to a reduced functional capability of stem cells. Therefore, major efforts have been invested to improve the repair capability of stem cells in aged individuals by overexpressing antisenescence and antiapoptotic genes. In this review, we describe critical genes and signaling pathways in stem cell aging and discuss ex vivo genetic modification approaches aimed at stem cell rejuvenation that are of interest for the cardiovascular system.

  1. Characterizing the epistemological development of physics majors

    Directory of Open Access Journals (Sweden)

    Elizabeth Gire

    2009-02-01

    Full Text Available Students in introductory physics courses are likely to have views about physics that differ from those of experts. However, students who continue to study physics eventually become experts themselves. Presumably these students either possess or develop more expertlike views. To investigate this process, the views of introductory physics students majoring in physics are compared with the views of introductory physics students majoring in engineering. In addition, the views of physics majors are assessed at various stages of degree progress. The Colorado learning attitudes about science survey is used to evaluate students’ views about physics, and students’ overall survey scores and responses to individual survey items are analyzed. Beginning physics majors are significantly more expertlike than nonmajors in introductory physics courses, and this high level of sophistication is consistent for most of undergraduate study.
