  3. Seventh annual National Conference of Black Physics students. Summary report, February 12--13, 1993

    Energy Technology Data Exchange (ETDEWEB)

    1993-12-31

    The 1993 conference hosted a wide variety of presentations and activities. Continuing the NCBPS tradition, we offered technical physics presentations, tours of physics research facilities, a career and educational fair, technical presentations by students, dinner speakers and a dance. New this, year were the interactive workshops (described in the section entitled ``New Features``). We included a ``celebrity`` speaker -- Col. Fred Gregory, an African-American NASA astronaut This presentation was featured on the local TV news. There were two last minute changes to the program They included: the replacement of Howard Adams and Tim Childs with Sylvia Wilson and Warren Buck, respectively. Howard Adams was ill and canceled a couple of days in advance. He recommended Sylvia Wilson, also of the GEM Program, as a replacement speaker. The substitution worked quite well, especially since our program was lacking in female speakers. Tim Childs missed his flight so Warren Buck, who attended the conference as an observer, generously filled in at the last minute. We ran a brief survey of the corporate, governmental and educational recruiters who were part of our Career/Educational Fair. Of 15 recruiters, 9 responded to the survey. All who responded said they were pleased with the conference arrangements. See Appendix C for the complete results of the Survey for Recruiters.

  6. Modified dispersion relations and black hole physics

    International Nuclear Information System (INIS)

    Ling Yi; Li Xiang; Hu Bo

    2006-01-01

    A modified formulation of the energy-momentum relation is proposed in the context of doubly special relativity. We investigate its impact on black hole physics. It turns out that such a modification will give corrections to both the temperature and the entropy of black holes. In particular, this modified dispersion relation also changes the picture of Hawking radiation greatly when the size of black holes approaches the Planck scale. It can prevent black holes from total evaporation, as a result providing a plausible mechanism to treat the remnant of black holes as a candidate for dark matter

  7. BOOK REVIEW: Introduction to Black Hole Physics Introduction to Black Hole Physics

    Science.gov (United States)

    Tanaka, Takahiro

    2012-07-01

    expected in the near future. Such hot topics are presented in Section 10: 'Black Holes and All That Jazz'. I would also consider the historical overview of the research on black holes given in Section 1 to be very interesting. Overall, I strongly recognised the intention of the authors not to go into too much detail; in this sense, I would say that the book has the aspect of a showcase of the frontiers of black hole physics. There are many topics which are very interesting but mathematically a little complicated; however, those subjects are appropriately treated so that the reader will not be overloaded with mathematical complexity. For example, in the discussion of black hole perturbation, only scalar field perturbation is discussed. The authors might have discussed gravitational wave perturbation, but this is much more complicated and the essential physics is mostly included in the simplest example of the scalar field. If I were one of the authors, I would consider adding more detailed explanations about several such advanced topics. However, the authors well know that such a challenge just presents a barrier to young students who are going to read this book, and really it is only an introduction to this interesting research field. This style might be the result of the long experience from the lectures over 30 years: the explanations of the subjects that the authors describe in detail are very carefully presented, avoiding logical gaps. In the preface, the authors state that they tried hard to answer students' questions as much as possible; I think that the authors' method in this respect is very successful.

  8. Surface effects in black hole physics

    International Nuclear Information System (INIS)

    Damour, T.

    1982-01-01

    This contribution reviews briefly the various analogies which have been drawn between black holes and ordinary physical objects. It is shown how, by concentrating on the properties of the surface of a black hole, it is possible to set up a sequence of tight analogies allowing one to conclude that a black hole is, qualitatively and quantitatively, similar to a fluid bubble possessing a negative surface tension and endowed with finite values of the electrical conductivity and of the shear and bulk viscosities. These analogies are valid simultaneously at the levels of electromagnetic, mechanical and thermodynamical laws. Explicit applications of this framework are worked out (eddy currents, tidal drag). The thermostatic equilibrium of a black hole electrically interacting with its surroundings is discussed, as well as the validity of a minimum entropy production principle in black hole physics.

  9. Hagedorn temperature and physics of black holes

    Directory of Open Access Journals (Sweden)

    Zakharov V.I.

    2016-01-01

    Full Text Available A mini-review devoted to some implications of the Hagedorn temperature for black hole physics. The existence of a limiting temperature is a generic feature of string models. The Hagedorn temperature was introduced first in the context of hadronic physics. Nowadays, the emphasis is shifted to fundamental strings which might be a necessary ingredient to obtain a consistent theory of black holes. The point is that, in field theory, the local temperature close to the horizon could be arbitrarily high, and this observation is difficult to reconcile with the finiteness of the entropy of black holes. After preliminary remarks, we review our recent attempt to evaluate the entropy of large black holes in terms of fundamental strings. We also speculate on implications for dynamics of large-Nc gauge theories arising within holographic models.

  11. Student Blogging about Physics

    Science.gov (United States)

    Daniels, Karen E.

    2010-09-01

    In traditional introductory physics classes, there is often limited opportunity for students to contribute their own ideas, interests, and experiences as they engage with the subject matter. This situation is exacerbated in university lecture-format classes, where students may not feel comfortable speaking during class. In the last few years, Internet blogs have become a decentralized format for diarists, independent journalists, and opinion makers to both post entries and allow commentary from their readers. Below, I will describe some techniques for using student blogging about physics to engage students from two different classroom environments: a calculus-based introductory mechanics class for scientists and engineers, and an honors seminar for first-year students. These assignments required them to make their own connections between classroom knowledge and situations where it might find applications. A second goal of including blogging in the introductory physics course was to induce students to write about the physics content of the class in a more substantive way than was previously part of the class.

  12. The Advanced Laboratory: beyond the ``black box'' to real physics

    Science.gov (United States)

    Zimmerman, George; Sulak, Lawrence

    2008-04-01

    The balance between theory and experiment in present physics curricula is too heavily weighted towards theory. Our physics majors do not realize that ``truth in physics'' depends either on experimental verification of theoretical predictions or on serendipitous discovery. Nor do they appreciate that most theories originate to explain experimental facts. They regard instruments as ``black boxes'' (although usually they are painted a different color). The Advanced Laboratory is essentially the only place in the curriculum where students confront the link between theory and experiment. In this age of disposing of (rather than repairing) equipment, Advanced Lab gives students insight into the inner workings of instruments and essential hands-on skills exploiting them: soldering wires, transferring cryo liquids, achieving high vacuum, acquiring reliable data, evaluating errors, fitting data, and drafting a PRL. Students learn techniques critical to several branches of physics, leading to different experimental approaches in their eventual work. If a student pursues theory, AdLab teaches her how to evaluate experiments, experimentalists, and their data. The basic skills learned, and the resulting understanding of physics, will be illustrated with the experiment on the Quantum Hall Effect from our AdLab.

  19. Structure of Black Male Students Academic Achievement in Science

    Science.gov (United States)

    Rascoe, Barbara

    Educational policies and practices have been largely unsuccessful in closing the achievement gap between Black and White students "Schwartz, 2001". This achievement gap is especially problematic for Black students in science "Maton, Hrabrowski, - Schmitt, 2000. Given the fact that the Black-White achievement gap is still an enigma, the purpose of this article is to address the Black female-Black male academic achievement gap in science majors. Addressing barriers that Black male students may experience as college science and engineering majors, this article presents marketing strategies relative to politics, emotional intelligence, and issues with respect to how science teaching, and Black male students' responses to it, are different. Many Black male students may need to experience a paradigm shift, which structures and enhances their science achievement. Paradigm shifts are necessary because exceptional academic ability and motivation are not enough to get Black males from their first year in a science, technology, education, and mathematics "STEM" major to a bachelor's degree in science and engineering. The conclusions focus on the balance of truth-slippery slopes concerning the confluence of science teachers' further ado and Black male students' theories, methods, and values that position their academic achievement in science and engineering majors.

  2. Introductory Physics Students' Physics and Mathematics Epistemologies

    Science.gov (United States)

    Scanlon, Erin M.

    The purpose of this three study dissertation is to investigate why students are enrolled in introductory physics courses experience difficulties in being successful; one possible source of their difficulties is related to their epistemology. In order to investigate students' epistemologies about mathematics and physics, students were observed solving physics problems in groups during a laboratory course (study 1) and while solving physics and mathematics problems individually during office-hour sessions (study 2). The Epistemological Resources theoretical framework was employed (Hammer & Elby, 2002). Using emergent and a priori epistemological resource operationalizations (Jones, 2015), 25 distinct epistemological resources were identified in study 1. Differences in physics epistemological resource usage between students of varying academic background (as measured by their number of previously completed mathematics and science classes were identified. By employing an external (Jones, 2015) and internal (Scanlon, 2016) a priori epistemological resource coding scheme, a total of 17 distinct epistemological resources were identified in study 2. The data were sampled to compare the mathematics and physics epistemological resource usage of participants with consistent and inconsistent sign usage in an energy conservation physics problem in order to provide a meaningful context for discussion. Participants of the same sign usage group employed epistemological resources similarly. Conversely, participants in different groups had significantly different physics epistemological resource usage patterns. Finally, student epistemological resource usage patterns from the first two studies were compared to course outcomes in order to determine implications for practice (study 3). Educators must be aware of and address the epistemological underpinnings of students' difficulties in introductory physics courses.

  3. Nonquasinormal modes and black hole physics.

    Science.gov (United States)

    Birmingham, Danny; Carlip, S

    2004-03-19

    The near-horizon geometry of a large class of extremal and near-extremal black holes in string and M-theory contains three-dimensional asymptotically anti-de Sitter space. Motivated by this structure, we are led naturally to a discrete set of complex frequencies defined in terms of the monodromy at the inner and outer horizons of the black hole. We show that the correspondence principle, whereby the real part of these "nonquasinormal frequencies" is identified with certain fundamental quanta, leads directly to the correct quantum behavior of the near-horizon Virasoro algebra, and thus the black hole entropy. Remarkably, for the rotating black hole in five dimensions we also reproduce the fractionization of conformal weights predicted in string theory.

  11. Andreev reflections and the quantum physics of black holes

    Science.gov (United States)

    Manikandan, Sreenath K.; Jordan, Andrew N.

    2017-12-01

    We establish an analogy between superconductor-metal interfaces and the quantum physics of a black hole, using the proximity effect. We show that the metal-superconductor interface can be thought of as an event horizon and Andreev reflection from the interface is analogous to the Hawking radiation in black holes. We describe quantum information transfer in Andreev reflection with a final state projection model similar to the Horowitz-Maldacena model for black hole evaporation. We also propose the Andreev reflection analogue of Hayden and Preskill's description of a black hole final state, where the black hole is described as an information mirror. The analogy between crossed Andreev reflections and Einstein-Rosen bridges is discussed: our proposal gives a precise mechanism for the apparent loss of quantum information in a black hole by the process of nonlocal Andreev reflection, transferring the quantum information through a wormhole and into another universe. Given these established connections, we conjecture that the final quantum state of a black hole is exactly the same as the ground state wave function of the superconductor/superfluid in the Bardeen-Cooper-Schrieffer (BCS) theory of superconductivity; in particular, the infalling matter and the infalling Hawking quanta, described in the Horowitz-Maldacena model, forms a Cooper pairlike singlet state inside the black hole. A black hole evaporating and shrinking in size can be thought of as the analogue of Andreev reflection by a hole where the superconductor loses a Cooper pair. Our model does not suffer from the black hole information problem since Andreev reflection is unitary. We also relate the thermodynamic properties of a black hole to that of a superconductor, and propose an experiment which can demonstrate the negative specific heat feature of black holes in a growing/evaporating condensate.

  13. Drawing minority students into the physics community

    Science.gov (United States)

    Gueye, Paul

    2013-03-01

    In the past few years, the number of African-American undergraduate physics students in the US had a steady decrease with dramatic consequences at many physics departments within Historically Black Colleges and Universities (HBCUs). A similar trend seems to also appear at the graduate level. HBCUs have been known to graduate more than 50% of undergraduate physics majors within this community for many years, a role that is now evaporating. The US African-American community cannot lose the historical and sometimes unnoticed impact of HBCUs in the physics community. The ability for these institutions to recruit, maintain and graduate students with the highest degree has turned a corner and is endangered with the recent closings of many programs. We not only must reverse this trend but also implement a sustainable growth for the future. This is an enormous task for the education community. While there are many outstanding and successful programs that have been developed over the years to target particular areas ranging from early K-12 exposure to producing MS and PhD students, each community/culture is different: one cannot transport someone else's experience and/or program and infuse it into another community. Moreover, the focus must now be comprehensive and not anymore single-centered. This talk will outline some ongoing efforts within the National Society of Black Physicists aimed at infusing a global approach to this problem that targets school districts (K-12) and after school programs, undergraduate and graduate programs within HBCUs, and the larger physic and scientific community.

  14. Teacher Education and Black Male Students in the United States

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available Teacher education programs in the United States (U.S. struggle to prepare teachers to meet the complex needs of elementary and secondary students in public schools - especially those of color, those living in poverty, and those whose first language is not English. In this article, we argue for focused attention on preparing educators to teach African American male students as these students face particular institutional challenges in successfully navigating the U.S. public school system. Drawing from the significant body of research on teacher education and teacher learning for equity and social justice, four Black teacher educators discuss challenges they have faced in classes designed to prepare teachers to teach Black male students. Through an analysis of commonalities in their experiences, they propose means for teacher educators to foster greater understandings of the heterogeneity found among Black male students so that teachers can craft more responsive and responsible educational experiences for Black males.

  17. Holography, black holes and condensed matter physics

    Science.gov (United States)

    Gentle, Simon Adam

    In this thesis we employ holographic techniques to explore strongly-coupled quantum field theories at non-zero temperature and density. First we consider a state dual to a charged black hole with planar horizon and compute retarded Green's functions for conserved currents in the shear channel. We demonstrate the intricate motion of their poles and stress the importance of the residues at the poles beyond the hydrodynamic regime. We then explore the collective excitations of holographic quantum liquids arising on D3/D5 and D3/D7 brane intersections as a function of temperature and magnetic field in the probe limit. We observe a crossover from hydrodynamic charge diffusion to a sound mode similar to the zero sound mode in the collisionless regime of a Landau Fermi liquid. The location of this crossover is approximately independent of the magnetic field. The sound mode has a gap proportional to the magnetic field, leading to strong suppression of spectral weight for intermediate frequencies and sufficiently large magnetic fields. In the second part we explore the solution space of AdS gravity in the hope of learning general lessons about such theories. First we study charged scalar solitons in global AdS4. These solutions have a rich phase space and exhibit critical behaviour as a function of the scalar charge and scalar boundary conditions. We demonstrate how the planar limit of global solitons coincides generically with the zero-temperature limit of black branes with charged scalar hair. We exhibit these features in both phenomenological models and consistent truncations of eleven-dimensional supergravity. We then discover new branches of hairy black brane in SO(6) gauged supergravity. Despite the imbalance provided by three chemical potentials conjugate to the three R-charges, there is always at least one branch with charged scalar hair, emerging at a temperature where the normal phase is locally thermodynamically stable.

  2. Nine optical black-box experiments for lower-secondary students

    Science.gov (United States)

    Rode, Henning; Friege, Gunnar

    2017-05-01

    In this paper a sequence of nine, easy to manufacture optical black-box experiments with increasing levels of difficulty, and supportive frameworks for physics classes are introduced. They have been evaluated in a lower-secondary school at the end of optics lessons. A black-box is a kind of experimental task where the inner structure is not visible to the experimenter. Using mirrors, beam-splitters, and blockers in a black-box to manipulate the light beam’s direction through this specific experiment, students are instructed to vary input and observe the output of light to get an idea of the possible inner structure. The presented sequence of black-box experiments requires a basic knowledge of the linear propagation of light and is suitable for beginner physics. Furthermore a framework for concrete implementation to physics classes is given, which covers suitable structure of class, examples for helpful worksheets, and authentic students’ solutions. The difficulty of the specific black-box experiments is given by the students’ success within observing input-output correlation and conclusion of an inner structure. The experiments’ implementation to physics classes may cover elaboration, practice, and aspects of the nature of science even in a beginner’s class. Evaluation has been conducted with students of young age (11-12 years old), however they are suitable for older students also. Although dealing with a time extensive sequence of experiments, students showed a high level of motivation throughout. Overall, implementing this sequence of black-box experiments is seen as valuable and helpful for physics classes.

  3. Applications of hidden symmetries to black hole physics

    2011-01-01

    This work is a brief review of applications of hidden symmetries to black hole physics. Symmetry is one of the most important concepts of the science. In physics and mathematics the symmetry allows one to simplify a problem, and often to make it solvable. According to the Noether theorem symmetries are responsible for conservation laws. Besides evident (explicit) spacetime symmetries, responsible for conservation of energy, momentum, and angular momentum of a system, there also exist what is called hidden symmetries, which are connected with higher order in momentum integrals of motion. A remarkable fact is that black holes in four and higher dimensions always possess a set ('tower') of explicit and hidden symmetries which make the equations of motion of particles and light completely integrable. The paper gives a general review of the recently obtained results. The main focus is on understanding why at all black holes have something (symmetry) to hide.

    As researchers categorize issues facing Black women's health, obesity and physical exercise continue to be significant topics of debate. General interventions targeted toward Black women to address obesity and increase physical exercise have been largely ineffective. In this article, I situate the current public health discourse on obesity and related interventions within a sociocultural context of body appearance, with a specific focus on hair. Why do some African American women feel such strong ties to their hair that they will avoid exercise? What can be done to understand this phenomenon and address alternatives that may make both hair maintenance and regular exercise feasible? I map a theoretical argument for why hair matters for some women, and discuss how physical activity intervention strategies might be improved by considering such complexities.

  8. Black Holes: Eliminating Information or Illuminating New Physics?

    Full Text Available Black holes, initially thought of as very interesting mathematical and geometric solutions of general relativity, over time, have come up with surprises and challenges for modern physics. In modern times, they have started to test our confidence in the fundamental understanding of nature. The most serious charge on the black holes is that they eat up information, never to release and subsequently erase it. This goes absolutely against the sacred principles of all other branches of fundamental sciences. This realization has shaken the very base of foundational concepts, both in quantum theory and gravity, which we always took for granted. Attempts to get rid of of this charge, have led us to crossroads with concepts, hold dearly in quantum theory. The sphere of black hole’s tussle with quantum theory has readily and steadily grown, from the advent of the Hawking radiation some four decades back, into domain of quantum information theory in modern times, most aptly, recently put in the form of the firewall puzzle. Do black holes really indicate something sinister about their existence or do they really point towards the troubles of ignoring the fundamental issues, our modern theories are seemingly plagued with? In this review, we focus on issues pertaining to black hole evaporation, the development of the information loss paradox, its recent formulation, the leading debates and promising directions in the community.

    McKay, Trinna S.

    Statement of the problem. Most student teachers successfully complete their educational programs; however, some continue to express concern about becoming an actual practicing teacher. One of these concerns deals with White teachers interactions with Black students. This study investigated White student teachers' perceptions of teaching Black students. In particular, the study examined the racial perceptions student teachers expressed about being a White person in a racially diverse school and examined the student teachers' perceptions on race. The following questions guided the study: (1) What are the perceptions of White student teachers concerning being White? (2) What are the perceptions of White student teachers on teaching science to Black students in a racially diverse secondary school? (3) What recommendations can White student teachers give to teacher education programs concerning the teaching of Black students? Methods. Semi-structured interviews, personal profiles and reflective journals were used as the means for collecting data. All three sources of data were used to understand the racial perceptions of each student teacher. Analysis of the data began with the identification of codes and categories that later developed into themes. Cross analyses between the data sources, and cross analysis between participants' individual data were conducted. The use of semi-structured interview, personal profiles, and reflective journals provided in-depth descriptions of the participants' racial perceptions. These data sources were used to confirm data and to show how student teaching experiences helped to shape their racial perceptions. Results. Data analysis revealed three themes, various life experiences, variety of opinions related to teaching Black students, and limited recommendations to teacher education programs. Although all teachers remained at the contact stage of the White racial identity model (Helms, 1990), they were open to dialogue about race. The

  13. Effects of student physical attractiveness

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available Implicit personality theories suggest that people draw conclusions about other persons by using a relatively small number of visible features. The formation of "the first impression" is influenced by the factors, such as sex, age, appearances, race or nationality. Frequently, conclusions based on those factors lead to developing social stereotypes. Attractiveness is a good example of "the first impression" effect, because physical attractiveness entails the creation of impression about another person along a relatively great number of dimensions. Experimental paradigm, introduced in the sphere of interpersonal perception around the mid-20th century, led to a relatively great number of studies on stereotype based on physical attractiveness. One of the most often quoted conclusions of studies on physical attractiveness is summarized by the idiom "what is beautiful is good". For example, socially desirable personality traits (responsibility kindness, energy quality, modesty, more successful private and professional life, are all attributed to physically attractive persons. In addition physical attractiveness is coupled with positive expectations, peer acceptance, academic achievement etc. On the basis of studies on the "what is beautiful is good" stereotype, we have situated our analysis within the domain of roles regulating social interaction between teachers and students i.e. effects of physical attractiveness on teacher expectations, peer acceptance and academic achievement.

  2. Inequality in education and quotas for black students in universities

    Directory of Open Access Journals (Sweden)

    Eunice R. Durham

    Full Text Available This article discusses the proposed definition of quotas for black students in universities in view of the widespread inequalities in the Brazilian educational system. The author defends that the proposed measure would lead to limitations and distortions, for it is based on rigid, artificial categories, in sharp contrast with the country's ethnic heterogeneity, and fails to consider key factors in the schooling experience of afro-descendants. The study of statistical series has shown that in spite of the progress made, there is still a great educational gap dividing white students from black and mulatto students. This led the author to conclude that public initiatives geared to reinforcing basic skills would constitute a more effective affirmative action than the establishment of quotas.

  3. Constraining jet physics in weakly accreting black holes

    2007-04-01

    Outflowing jets are observed in a variety of astronomical objects such as accreting compact objects from X-ray binaries (XRBs) to active galactic nuclei (AGN), as well as at stellar birth and death. Yet we still do not know exactly what they are comprised of, why and how they form, or their exact relationship with the accretion flow. In this talk I will focus on jets in black hole systems, which provide the ideal test population for studying the relationship between inflow and outflow over an extreme range in mass and accretion rate. I will present several recent results from coordinated multi-wavelength studies of low-luminosity sources. These results not only support similar trends in weakly accreting black hole behavior across the mass scale, but also suggest that the same underlying physical model can explain their broadband spectra. I will discuss how comparisons between small- and large-scale systems are revealing new information about the regions nearest the black hole, providing clues about the creation of these weakest of jets. Furthermore, comparisons between our Galactic center nucleus Sgr A* and other sources at slightly higher accretion rates can illucidate the processes which drive central activity, and pave the way for new tests with upcoming instruments.

    Few studies have reported on the validity of physical activity measures in African Americans. The present study was designed to determine the validity of a self-administered physical activity questionnaire (PAQ) that was used in a large prospective study of African American women in the United States against an accelerometer (actigraph), an objective assessment of movement, and a seven-day activity diary. The study was conducted among 101 women enrolled in the Black Women's Health Study (BWHS) cohort who resided in the Washington, DC, metropolitan area, representing 11.2% (101/900) of this sample. Physical activity levels were obtained from the parent BWHS PAQ (eg, 1997 and 1999) and repeated in the present study. This information entailed hours per week of participation in walking for exercise, hours per week of moderate activity (eg, housework, gardening, and bowling), and hours per week of strenuous activity (eg, basketball, swimming, running, and aerobics) during the previous year. The participants were required to wear actigraphs for seven days and then record their physical activities in their diaries (seven-day physical activity diary) during this time. The diaries were used to record the amount and pattern of daily energy expenditure. Significant positive correlations were seen between the BWHS PAQ and the actigraph for total activity, r=.28; walking, r=.26; and vigorous activity, r=.40, PPAQ also demonstrated significant correlations for total (r=0.42, PPAQ is a useful measure of physical activity in the BWHS cohort and thus has utility in prospective epidemiologic research.

    Full Text Available The aim of the study was to reveal pattern of physical activity among students and to investigate which types of physical activity are dominantly present among the students. Also, the aim was to investigate the attitudes of students towards the importance of physical activity as well as to determine the reasons for the possible lack of physical activity. The research was conducted at the Students' Center Kragujevac and included 403 students from six different faculties of the University of Kragujevac. The data were collected by a questionnaire designed for the purpose of this investigation, made up of two parts. After demographic data, the first part of the questionnaire consisted of questions about the pattern of physical activity, and the second part contained questions related to attitudes about physical activity. A statistical analysis was performed using SPSS version 21.00. Based on the IPAQ directives for scoring and criteria for classification of physical activity 23.3% of students were physically inactive, 62.5% were classified as moderate and 14.2% fell in the category of high physical activity. When it comes to attitudes of the respondents, 56.6% of the students' population did not consider to engage in regular physical activity or planned to start it in the future. What makes most of the respondents (60.3% to be more physically active is knowledge about importance of physical activity for health. There are many reasons for insufficient physical activity but the majority of (87.8% of the students stressed lack of time as a crucial reason. Majority of the interviewed students of University of Kragujevac were aware of importance which physical activity has on health, but they also for different reasons (from which lack of time was the most dominant did not engage enough in physical activities.

    Black holes as solutions to gravity theories, are generically identified by a set of parameters. Some of these parameters are associated with black hole physical conserved charges, like ADM charges. There can also be some “redundant parameters.” We propose necessary conditions for a parameter to be physical. The conditions are essentially integrability and non-triviality of the charge variations arising from “parametric variations,” variation of the solution with respect to the chosen parameters. In addition, we prove that variation of the redundant parameters which do not meet our criteria do not appear in the first law of thermodynamics. As an interesting application, we show that dilaton moduli are redundant parameters for black hole solutions to Einstein–Maxwell–(Axion)–Dilaton theories, because variations in dilaton moduli would render entropy, mass, electric charges or angular momenta non-integrable. Our results are in contrast with modification of the first law due to scalar charges suggested in Gibbons–Kallosh–Kol paper and its follow-ups. We also briefly discuss implications of our results for the attractor behavior of extremal black holes.

    2003-01-01

    An orbiting black hole binary will generate strong gravitational radiation signatures, making these binaries important candidates for detection in gravitational wave observatories. The gravitational radiation is characterized by the orbital parameters, including the frequency and separation at the innermost stable circular orbit (ISCO). One approach to estimating these parameters relies on a sequence of initial data slices that attempt to capture the physics of the inspiral. Using calculations of the binding energy, several authors have estimated the ISCO parameters using initial data constructed with various algorithms. In this paper we examine this problem using conformally Kerr-Schild initial data. We present convergence results for our initial data solutions, and give data from numerical solutions of the constraint equations representing a range of physical configurations. In a first attempt to understand the physical content of the initial data, we find that the Newtonian binding energy is contained in the superposed Kerr-Schild background before the constraints are solved. We examine some deficiencies with the initial data approach to orbiting binaries, especially touching on the effects of prior motion and spin-orbital coupling of the angular momenta. Making rough estimates of these effects, we find that they are not insignificant compared to the binding energy, leaving some doubt of the utility of using initial data to predict ISCO parameters. In computations of specific initial-data configurations we find spin-specific effects that are consistent with analytical estimates

  12. Feminist Physics Education: Deconstructed Physics and Students' Multiple Subjectivities

    Science.gov (United States)

    Jammula, Diane Crenshaw

    Physics is one of the least diverse sciences; in the U.S. in 2010, only 21% of bachelors degrees in physics were awarded to women, 2.5% to African Americans, and 4% to Hispanic Americans (AIP, 2012). Though physics education reform efforts supporting interactive engagement have doubled students' learning gains (Hake, 1998), gender and race gaps persist (Brewe et al., 2010; Kost, Pollock, & Finkelstein, 2009). When students' subjectivities align with presentations of physics, they are more likely to develop positive physics identities (Hughes, 2001). However, both traditional and reformed physics classrooms may present physics singularly as abstract, elite, and rational (Carlone, 2004). Drawing from feminist science, I argue that binaries including abstract / concrete, elite / accessible, and rational / emotional are hierarchal and gendered, raced and classed. The words on the left define conventional physics and are associated with middle class white masculinity, while the words on the right are associated with femininity or other, and are often missing or delegitimized in physics education, as are females and minorities. To conceptualize a feminist physics education, I deconstructed these binaries by including the words on the right as part of doing physics. I do not imply that women and men think differently, but that broadening notions of physics may allow a wider range of students to connect with the discipline. I used this conceptual framework to modify a popular reformed physics curriculum called Modeling Instruction (Hestenes, 1987). I taught this curriculum at an urban public college in an introductory physics course for non-science majors. Twenty-three students of diverse gender, race, ethnic, immigrant and class backgrounds enrolled. I conducted an ethnography of the classroom to learn how students negotiate their subjectivities to affiliate with or alienate from their perceptions of physics, and to understand how classroom experiences exacerbate or

    This study sought to validate the Self-Perception Profile for College Students (Neemann and Harter, 1986) by investigating the perceived competence of physical education students as compared to students enrolled in other academic programs. Group One comprised 114 physical education students. Group Two consisted of 209 subjects enrolled in other academic programs. The Self-Perception Profile for College Students was administered to all subjects. Five scales (athletic, scholastic, social acceptance, appearance, and global self-worth) were analyzed. Factor analysis and internal consistency measures provided psychometric support for the scales. Separate ANOVAs calculated for each scale revealed that physical education students had higher perceptions of athletic competence than the other students. Males had higher perceptions of athletic and appearance competence, whereas females had higher perceived social acceptance. These findings are discussed in terms of psychometric issues, and the relationship between perceived competence and motivational patterns.

These talks will begin with an overview of the basics of black hole physics, and then briefly summarize some of the exciting developments with cosmic black holes. They will then turn to properties of quantum black holes, and the question of black hole production in high energy collisions, perhaps beginning with the LHC. I will then overview the apparent paradox emerging from Hawking's discovery of black hole evaporation, and what it could be teaching us about the foundations of quantum mechanics and gravity.

    2015-09-01

    Full Text Available One thesis of Social Identity Theory developed by Henri Tajfel proposes the existence of in-group favoritism. Judgments related to in-group members are more favorable than those referred to out-groups subjects in order to sustain a positive social identity. Results obtained in researches carried out in last decade (Marques and Páez; 1996, 1999 throw a new shade to that proposal. When judged behavior or attribute is anti norm or deviate, subjects are more severe in their judgments with the in-group member in comparison with out-group ones revealing a “black sheep effect” (BSE. Based on those statements, a transcultural research was carried out with psychology student’s samples from different countries. The objective was to analyze the in-group favoritism and “black sheep effect” and, go further in subjects “extremity” judgments related to in-group and out-group members. Argentine sample is composed by 140 psychology students of Buenos Aires city. Results, similar to ones from other countries samples, corroborate in general the “black sheep effect” and refute the in-group favoritism when the behavior or attribute under judgment is negative or anti-normative.

    2015-08-01

    Full Text Available This paper aims to describe and analyze some data from an extension project and research titled “The narratives of the self and the effects of affirmative action policies to black students who need of affirmative action and Africans." We have as central issues of our work the following questions: What do the students who need of affirmative action and not unitholders know about the quotas? What do the various African groups who are at university know about the quotas and their experience as a student in the Alagoas’ State? In methodological terms, we use some procedures and instruments of action research to raise our diagnostic procedures and social intervention. It is concluded after investigation that the affirmative action policies in college should be the subject of constant debate whether in academia or in society. There is ignorance on the part of students who need of affirmative action, not unitholders and africans student about the racial quotas, the policies of affirmative action and the collective human rights achievements and socio-historical character.

  13. The black hole symphony: probing new physics using gravitational waves.

    Gair, Jonathan R

    2008-12-13

    The next decade will very likely see the birth of a new field of astronomy as we become able to directly detect gravitational waves (GWs) for the first time. The existence of GWs is one of the key predictions of Einstein's theory of general relativity, but they have eluded direct detection for the last century. This will change thanks to a new generation of laser interferometers that are already in operation or which are planned for the near future. GW observations will allow us to probe some of the most exotic and energetic events in the Universe, the mergers of black holes. We will obtain information about the systems to a precision unprecedented in astronomy, and this will revolutionize our understanding of compact astrophysical systems. Moreover, if any of the assumptions of relativity theory are incorrect, this will lead to subtle, but potentially detectable, differences in the emitted GWs. Our observations will thus provide very precise verifications of the theory in an as yet untested regime. In this paper, I will discuss what GW observations could tell us about known and (potentially) unknown physics.

  1. From students to researchers: The education of physics graduate students

    Science.gov (United States)

    Lin, Yuhfen

    This dissertation aims to make two research contributions: (1) In physics education research, this work aims to advance our understanding of physics student learning at the graduate level. This work attempts to better understand how physics researchers and teachers are produced, and what factors support or encourage the process of becoming a researcher and a teacher. (2) In cognitive science research in the domain of expert/novice differences, researchers are interested in defining and understanding what expertise is. This work aims to provide some insight into some of the components of expertise that go into becoming a competent expert researcher in the domain of physics. This in turn may contribute to our general understanding of expertise across multiple domains. Physics graduate students learn in their classes as students, teach as teaching assistants, and do research with research group as apprentices. They are expected to transition from students to independent researchers and teachers. The three activities of learning, teaching, and research appear to be very different and demand very different skill-sets. In reality, these activities are interrelated and have subtle effects on each other. Understanding how students transition from students to researchers and teachers is important both to PER and physics in general. In physics, an understanding of how physics students become researchers may help us to keep on training physicists who will further advance our understanding of physics. In PER, an understanding of how graduate students learn to teach will help us to train better physics teachers for the future. In this dissertation, I examine physics graduate students' approaches to teaching, learning, and research through semi-structured interviews. The collected data is interpreted and analyzed through a framework that focuses on students' epistemological beliefs and locus of authority. The data show how students' beliefs about knowledge interact with their

    Castillo, A. J.; Marshall, J.; Cardenas, M. B.

    2012-12-01

    Our objective is to characterize and assess upper division and graduate student thinking by developing and testing an assessment tool for a physical hydrology class. The class' learning goals are: (1) Quantitative process-based understanding of hydrologic processes, (2) Experience with different methods in hydrology, (3) Learning, problem solving, communication skills. These goals were translated into two measurable tasks asked of students in a questionnaire: (1) Describe the significant processes in the hydrological cycle and (2) Describe laws governing these processes. A third question below assessed the students' ability to apply their knowledge: You have been hired as a consultant by __ to (1) assess how urbanization and the current drought have affected a local spring and (2) predict what the effects will be in the future if the drought continues. What information would you need to gather? What measurements would you make? What analyses would you perform? Student and expert responses to the questions were then used to develop a rubric to score responses. Using the rubric, 3 researchers independently blind-coded the full set of pre and post artifacts, resulting in 89% inter-rater agreement on the pre-tests and 83% agreement on the post-tests. We present student scores to illustrate the use of the rubric and to characterize student thinking prior to and following a traditional course. Most students interpreted Q1 in terms of physical processes affecting the water cycle, the primary organizing framework for hydrology, as intended. On the pre-test, one student scored 0, indicating no response, on this question. Twenty students scored 1, indicating rudimentary understanding, 2 students scored a 2, indicating a basic understanding, and no student scored a 3. Student scores on this question improved on the post-test. On the 22 post-tests that were blind scored, 11 students demonstrated some recognition of concepts, 9 students showed a basic understanding, and 2

    Kelly, Angela M.

    2010-10-01

    Urban students often have limited opportunities to study physics in high school; many schools, particularly in high poverty areas, do not have the resources and capital to provide physics courses for those who wish to enroll. The Bronx Institute at Lehman College has initiated several programs for Black and Latino youth to enroll in physics classes and progress to college-level physics while still in high school. Students with promise from the surrounding community have been recruited to participate in afterschool and summer classes, taught by university faculty. Examples of student reflections illustrate the collective impact of high expectations, access to rigorous physics study, and a communal, supportive learning environment. Initial experiences with the first two cohorts will be shared, along with curriculum plans for a comprehensive physics sequence to prepare students for admission to competitive colleges and participation in future STEM study and careers.

    As educators and researchers in the field of photonics, we find what we do to be very exciting, and sharing this passion and excitement to our university students is natural to us. Via outreach programs and college research funding, a new college and university collaboration has broadened our student audience: photonics is brought into the college classroom and research opportunities are provided to college students. Photonics-themed active learning activities are conducted in the college Waves and Modern Physics class, helping students forge relationships between course content and modern communications technologies. Presentations on photonics research are prepared and presented by the professor and past college student-researchers. The students are then given a full tour of the photonics university laboratories. Furthermore, funds are set aside to give college students a unique opportunity to assist the college professor with experiments during a paid summer research internship.

    2002-01-01

    A prototype of an asymptotically non-flat black hole spacetime is that of a Schwarzschild black hole in the background of the Einstein universe, which is a special case of the representation of a black hole in a cosmological background given by Vaidya. Recently, this spacetime has been studied in detail by Nayak et al. They constructed a composite spacetime called the Vaidya-Einstein-Schwarzschild (VES) spacetime. We investigate some of the physical effects inherent to this spacetime. We carry out a background-black hole decomposition of the spacetime in order to separate out the effects due to the background spacetime and the black hole. The physical effects we study include the classical tests - the gravitational redshift, perihelion precession and light bending - and circular geodesics. A detailed classification of geodesics, in general, is also given

    Hope, Elan C; Velez, Gabriel; Offidani-Bertrand, Carly; Keels, Micere; Durkee, Myles I

    2018-01-01

    The current study investigates the utility of political activism as a protective factor against experiences of racial/ethnic (R/E) discrimination that negatively affect stress, anxiety, and depressive symptoms among Black and Latinx college freshmen at predominately White institutions. Data come from the Minority College Cohort Study, a longitudinal investigation of Black and Latinx college students (N = 504; 44% Black). We conducted multiple regression analyses for each mental health indicator and tested for interaction effects. For Black and Latinx students, the relationship between R/E microaggressions and end of freshman year stress varied by political activism. For Black students, the relationship between R/E microaggressions and end of the year anxiety varied by political activism. There was a significant interaction effect for depressive symptoms among Latinx students. Political activism serves as a protective factor to mitigate the negative effect of R/E discrimination on stress and depressive symptoms for Latinx students. For Black students, higher levels of political activism may exacerbate experiences of R/E microaggressions and relate to more stress and anxiety compared with Black students who are less politically involved. Findings point to the need for a deeper understanding of phenomenological variation in experiences of microaggressions among R/E minorities and how students leverage political activism as an adaptive coping strategy to mitigate race-related stress during college.

    Castro, Alejandra; Kraus, Per; Larsen, Finn

    2008-01-01

    We review recent developments in understanding quantum/string corrections to BPS black holes and strings in five-dimensional supergravity. These objects are solutions to the effective action obtained from M-theory compactified on a Calabi-Yau threefold, including the one-loop corrections determined by anomaly cancellation and supersymmetry. We introduce the off-shell formulation of this theory obtained through the conformal supergravity method and review the methods for investigating supersymmetric solutions. This leads to quantum/string corrected attractor geometries, as well as asymptotically flat black strings and spinning black holes. With these solutions in hand, we compare our results with analogous studies in four-dimensional string-corrected supergravity, emphasizing the distinctions between the four and five dimensional theories.

  11. Successful White teachers of Black students: Teaching across racial lines in urban middle school science classrooms

    Science.gov (United States)

    Coleman, Bobbie

    The majority of urban minority students, particularly Black students, continue to perform below proficiency on standardized state and national testing in all areas that seriously impact economically advanced career options, especially in areas involving science. If education is viewed as a way out of poverty, there is a need to identify pedagogical methodologies that assist Black students in achieving higher levels of success in science, and in school in general. The purpose of this study was to explore White teachers' and Black students' perceptions about the teaching strategies used in their low socioeconomic status (LSES) urban science classrooms, that led to academic success for Black students. Participants included three urban middle school White teachers thought to be the best science teachers in the school, and five randomly selected Black students from each of their classrooms. Methods of inquiry involving tenets of grounded theory were used to examine strategies teachers used to inspire Black students into academic success. Data collection included teacher and student interviews, field notes from classroom observations, group discussions, and questionaires. Data were analyzed using open, axial, and selective coding. The teachers' perceptions indicated that their prior belief systems, effective academic and personal communication, caring and nurturing strategies, using relevant and meaningful hands-on activities in small learner-centered groups, enhanced the learning capabilities of all students in their classrooms, especially the Black students. Black students' perceptions indicated that their academic success was attributable to what teachers personally thought about them, demonstrated that they cared, communicated with them on a personal and academic level, gave affirmative feedback, simplified, and explained content matter. Black students labeled teachers who had these attributes as "nice" teachers. The nurturing and caring behaviors of "nice" teachers

    2014-01-01

    Full Text Available Differences in student performance were analyzed for Black males in Connecticut, Florida, Maryland, Massachusetts, and Texas on the Advanced Placement English Language and Composition, Calculus AB, Biology, and United States History examinations from the 2001 through the 2012 exam years. All analyses included in the comparisons of overall examination scores and U.S. History examination scores were statistically significant. Of the 48 individual examination comparisons, 26 yielded evidence of a statistically significant difference among the Black male students from the selected states. Massachusetts was the state with the highest percentages of Black male students who achieved an AP score of 4 or 5. Conversely, Texas was the state with the highest percentages of Black male students who failed to achieve an AP score of 4 or 5. Implications for policy regarding advanced placement testing as an avenue for preparing students for college and recommendations for future research are discussed.

    Full Text Available Throughout its journey universe follows strong gravity. By unifying general theory of relativity and quantum mechanics a simple derivation is given for rotating black hole’s temperature. It is shown that when the rotation speed approaches light speed temperature approaches Hawking’s black hole temperature. Applying this idea to the cosmic black hole it is noticed that there is “no cosmic temperature” if there is “no cosmic rotation”. Starting from the Planck scale it is assumed that- universe is a rotating and expanding black hole. Another key assumption is that at any time cosmic black hole rotates with light speed. For this cosmic sphere as a whole while in light speed rotation “rate of decrease” in temperature or “rate of increase” in cosmic red shift is a measure of “rate of cosmic expansion”. Since 1992, measured CMBR data indicates that, present CMB is same in all directions equal to 2 : 726 K ; smooth to 1 part in 100,000 and there is no continuous decrease! This directly indicates that, at present rate of decrease in temperature is practically zero and rate of expansion is practically zero. Universe is isotropic and hence static and is rotating as a rigid sphere with light speed.

  10. Black Hole Binaries: The Journey from Astrophysics to Physics

    Science.gov (United States)

    McClintock, Jeffrey E.

    This paper is based on a talk presented at the 208th Meeting of the American Astronomical Society in the session on Short-Period Binary Stars. The talk (and this paper in turn) are based on a parent paper, which is a comprehensive review by Remillard and McClintock (2006; hereafter RM06) on the X-ray properties of binary stars that contain a stellar black-hole primary. We refer to these systems as black hole binaries. In this present paper, which follows closely the content of the talk, we give sketches of some of the main topics covered in RM06. For a detailed account of the topics discussed herein and a full list of references (which are provided only sketchily below), see RM06 and also a second review paper by McClintock & Remillard (2006; hereafter MR06). There is one subject that is treated in more detail here than in the two review papers just cited, namely, the measurement of black hole spin; on this topic, see McClintock et al. (2006) for further details and references.

    Supermassive black holes with masses of millions to billions of solar masses are commonly found in the centers of galaxies. Astronomers seek to image jet formation using radio interferometry but still suffer from insufficient angular resolution. An alternative method to resolve small structures is to measure the time variability of their emission. Here we report on gamma-ray observations of the radio galaxy IC 310 obtained with the MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescopes, revealing variability with doubling time scales faster than 4.8 min. Causality constrains the size of the emission region to be smaller than 20% of the gravitational radius of its central black hole. We suggest that the emission is associated with pulsar-like particle acceleration by the electric field across a magnetospheric gap at the base of the radio jet.

    Kinnett-Hopkins, Dominique; Motl, Robert W

    2016-04-01

    To examine variables from social cognitive theory as correlates of physical activity in black and white individuals with multiple sclerosis (MS). Cross-sectional. National survey. Black (n=151) and white (n=185) individuals with MS were recruited through the North American Research Committee on Multiple Sclerosis Registry. Not applicable. The battery of questionnaires included information on demographic and clinical characteristics, physical activity, exercise self-efficacy, function, social support, exercise outcome expectations, and exercise goal setting and planning. Black individuals with MS reported significantly lower levels of physical activity compared with white individuals with MS. Physical activity levels were significantly correlated with self-efficacy, outcome expectations, functional limitations as impediments, and goal setting in black participants with MS. The pattern and magnitude of correlations were comparable with those observed in white participants based on Fisher z tests. Researchers should consider applying behavioral interventions that target social cognitive theory variables for increasing physical activity levels among black individuals with MS.

    2015-04-01

    We evaluated the association between intimate partner violence and the mental and physical health status of US Caribbean Black and African American women. We used 2001 to 2003 cross-sectional data from the National Survey of American Life-the most detailed study to date of physical and mental health disorders of Americans of African descent. We assessed participants' health conditions by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (Washington, DC; American Psychological Association) Composite International Diagnostic Interview. We found differences in health conditions between abused African American and Caribbean Black women. There were increased risks for lifetime dysthymia, alcohol dependence, drug abuse, and poor perceived health for African American victims of partner abuse, and binge eating disorder was associated with partner violence among Caribbean Black women. Severe intimate partner violence was associated with negative mental and physical health outcomes for US Black women, with different patterns between African American and Caribbean Blacks. Understanding intimate partner violence experiences of US Black women requires recognition of key intragroup differences, including nativity and immigrant status, and their differential relationships to women's health.

    Hill, O W; Clark, J L

    1993-06-01

    This study examined the distributions across personality types (as assessed by the Myers-Briggs Type Indicator) of two samples of black college students (ns = 315 and 447) in comparison to norming data from two manuals. Major differences were found between the black and white samples with regard to the proportions classified as Extroversion-Intuition-Feeling-Perception (ENFP) and Introversion-Sensing-Thinking-Judging (ISTJ). Much higher proportions of the black samples were also clustered at the sensing pole of the perceptual dimension. The findings are discussed in terms of their implications for the existence of a unique black "cognitive style."

    Recruiting talent and fostering innovation in STEM (Science, Technology, Engineering and Mathematics) disciplines demands that we attract, educate, and retain a larger and more diverse cohort of students. In this regard, Community Colleges (CC), serving a disproportionate number of underrepresented minority, female and nontraditional students, represent a pool of potential talent that, due to a misguided perception of its students as being less capable, often remains untapped. We will present our strategies to attract and support the academic advancement of CC students in the STEM fields through our NSF-sponsored Research Experience for Undergraduates program entitled Internships in Nanosystems Science Engineering and Technology (INSET). For more than a decade, INSET has offered a physics research projects to CC students. The key components of INSET success are: 1) the involvement of CC faculty with a strong interest in promoting student success in all aspects of program planning and execution; 2) the design of activities that provide the level of support that students might need because of lack of confidence and/or unfamiliarity with a university environment; and 3) setting clear goals and high performance expectations.

    2009-05-01

    There is limited information about African American students attending Historically Black Colleges and Universities (HBCUs) in the areas of health behavior, health knowledge, and attitudes. To fill this gap, a comprehensive examination offirst-year students was undertaken at a consortium of HBCUs. A non-random sample of 1115 freshmen were administered a survey that assessed several domains including: (1) demographics, (2) general health, (3) smoking habits, (4) disease risk, (5) weight perception, (6) physical activity, (7) perceived stress, (8) eating habits, (9) social support, (10) personal/family medical history, (11) leadership, (12) domestic violence, (13) substance use, and (14) sexual behavior. In general, most students knew about health behaviors and disease risk. Areas that warrant further exploration include physical activity, sexual behavior, and drug use. The analyses provide key information for health education and prevention.

    Full Text Available Purpose : to develop and experimentally substantiate fitness technology for students taking into account their individual peculiarities. Material : The experiment was performed by girls (n=51, age 17-20 who were divided into experimental (n=25 and control (n=26 groups. Classes were held twice a week during the year: 66 hours in the hall and 95 hours of independent study. At the beginning and at the end of the study, all students met the control standards, which allowed to determine the level of development of physical qualities and level of physical fitness. Results : 8 exercise complexes were developed to implement our fitness technology. Complexes were taken into account: interests, age, individual characteristics and level of physical fitness of students. At the first lessons the loading was about 45-50%. In the future, the loading increases to 70-75% of the total time of classes. Conclusions : When constructing fitness technology using varieties of fitness it is necessary to take into account: the type and nature of exercises, the volume and intensity of exercises, the number of repetitions and the amount of weight, the frequency of training sessions and the duration of work, intervals of rest, the number and alternation of exercises.

    a) To know the eating and exercising habits of undergraduate Physical Therapy students; b) To promote awareness among these future health professionals and educators of the need to foster adequate eating habits among patients and the general population. A dietary and physical activity questionnaire, regarding a seven-day period, distributed among students of the School of Physical Therapy (University of Valladolid) in the city of Soria, Spain (n = 131; sex (m/f): 38/93). Results show that a high percentage of the subjects follow the recommendations of the new Nutritional Pyramid of the Spanish Nutrition Society (SEN) regarding intake of meat, fish, milk, dairy products and exercise habits. This is not the case, however, for products such as pasta, bread and cereals, vegetables, fruits, legumes and olive oil. Furthermore, fast food is taken, on average, once a week despite the recommended sporadic monthly intakes. According to results, formative programmes should be carried out to enable these students to encourage healthy diets. Thus, diseases related to non-healthy eating habits could be prevented, and information on the issue could be spread among the population.

  15. The roots of physics students' motivations: Fear and integrity

    Science.gov (United States)

    Van Dusen, Ben

    Too often, physics students are beset by feelings of failure and isolation rather than experiencing the creative joys of discovery that physics has to offer. This dissertation research was founded on the desire of a teacher to make physics class exciting and motivating to his students. This work explores how various aspects of learning environments interact with student motivation. This work uses qualitative and quantitative methods to explore how students are motivated to engage in physics and how they feel about themselves while engaging in physics. The collection of four studies in this dissertation culminates in a sociocultural perspective on motivation and identity. This perspective uses two extremes of how students experience physics as a lens for understanding motivation: fear and self-preservation versus integrity and self-expression. Rather than viewing motivation as a property of the student, or viewing students as inherently interested or disinterested in physics, the theoretical perspective on motivation and identity helps examine features of the learning environments that determine how students' experience themselves through physics class. This perspective highlights the importance of feeling a sense of belonging in the context of physics and the power that teachers have in shaping students' motivation through the construction of their classroom learning environments. Findings demonstrate how different ways that students experience themselves in physics class impact their performance and interest in physics. This dissertation concludes with a set of design principles that can foster integration and integrity among students in physics learning environments.

    As with any black hole, asymptotically anti-de Sitter Kerr black holes are described by a small number of parameters, including a ''mass parameter'' M that reduces to the AdS-Schwarzschild mass in the limit of vanishing angular momentum. In sharp contrast to the asymptotically flat case, the horizon area of such a black hole increases with the angular momentum parameter a if one fixes M; this appears to mean that the Penrose process in this case would violate the Second Law of black hole thermodynamics. We show that the correct procedure is to fix not M but rather the ''physical'' mass E=M/(1−a{sup 2}/L{sup 2}){sup 2}; this is motivated by the First Law. For then the horizon area decreases with a. We recommend that E always be used as the mass in physical processes: for example, in attempts to ''over-spin'' AdS-Kerr black holes.

    Lorimer, Dunan

    2013-01-01

    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.

  1. A comprehensive program to develop correlations for physical properties of kraft black liquor. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Fricke, A.L.; Zaman, A.A.

    1998-05-01

    The overall objective of the program was to develop correlations to predict physical properties within requirements of engineering precision from a knowledge of pulping conditions and of kraft black liquor composition, if possible. These correlations were to include those relating thermodynamic properties to pulping conditions and liquor composition. The basic premise upon which the research was based is the premise that black liquor behaves as a polymer solution. This premise has proven to be true, and has been used successfully in developing data reduction methods and in interpreting results. A three phase effort involving pulping, analysis of liquor composition, and measurement of liquor properties was conducted.

    Full Text Available The peculiarities of formation of personal physical training of students from various universities. The experiment was attended by 748 students. It is shown that the most significant factor in personal physical training of students is to conduct a healthy physically active lifestyle and relationship to the body as a value. It is confirmed that for students of physical culture the main motivational factors for physical culture and sports activities is the desire to improve physical fitness, achieve sporting success. For students of non-core specialties - to optimize the weight and improve the shape. It is proved that the main obstacle to employment physical and sports activities of the students is the lack of free time. It is shown that only 21.2% of students believe their non-core specialties: motor sufficient for normal life and preservation of health.

    2015-01-01

    Full Text Available Studies have shown that a positive attitude towards physical education (PE is in connection with students' engagement in PE classes and with the development of an active lifestyle. The objective of this study was to examine attitudes of early adolescent age students towards physical education, as well as to examine whether such attitudes vary with regard to gender, grade they attend and students' engagement in sport and physical exercises in extracurricular activities. The research was conducted on the sample of 531 students from 6th to 8th grade. The instrument Student's Attitudes toward Physical Education - SATPE was used to measure student's attitude towards PE. A special questionnaire was used to collect data on gender, grade and engagement in sport and physical exercising outside school. The results have shown that students have positive attitudes of moderate intensity towards physical education. MANOVA has shown that male students have more positive attitudes than female students, as well as that positivity of attitudes declines with age. Likewise, it was shown that students with more positive attitudes towards PE are more often engaged in physical exercises outside school. The connection between the attitude towards PE and involvement in organized sport was not confirmed. The paper presents suggestions for further research of students' attitude towards PE and its connection with physical activity of students.

  10. Health risk behaviors of black male college students: seat belt use, smoking, and obesity status.

    Ajibade, Phoebe Butler

    2010-01-01

    This paper examined health behaviors (seatbelt use, tobacco use, and obesity status) of 127 black male college students using data obtained from the National College Health Risk Behavior Survey. The majority of the participants were freshmen and sophomores (70%), full time students (95%), and lived on campus (85%). The results indicated that black males often failed to use seatbelts while riding as a passenger (69%) or driving (48%). Although 15% of the students smoked, 1/3 of the smokers began smoking during college. Approximately 50% of the students were overweight or obese; among students attempting to lose weight, exercise versus nutrient intake was used as a means to lose weight. The study recommendations included the need to increase educational efforts to alert black males to their risks for a premature death, and to provide programming/mentoring initiatives to assist males in dealing with stress and discrimination that may impact their health-related decision making. The implications of this study suggest that even educated black males are at risk for premature disease and disability as a result of their health behaviors.

  11. Eliciting physics students mental models via science fiction stories

    Acar, H.

    2005-01-01

    This paper presents the results of an experiment which investigated the effects of the using science fiction stories in physics lessons. A questionnaire form containing 2 open-ended questions related to Jules Vernes story From the Earth to the Moon was used with 353, 9th and 10th grade students to determine their pre-conceptions about gravity and weightlessness. Mental models explaining students scientific and alternative views were constructed, according to students replies. After these studies, 6 students were interviewed. In this interview, researches were done about whether science fiction stories had an effect on bringing students pre-conceptions related to physics subjects out, on students inquiring their own concepts and on increasing students interest and motivation towards physics subjects. Studies in this research show that science fiction stories have an effect on arousing students interest and curiosity, have a role encouraging students to inquire their own concepts and are effective in making students alternative views come out

  13. Harnessing Students' Interest in Physics with Their Own Video Games

    Science.gov (United States)

    Like, Christopher

    2011-04-01

    Many physics teachers assign projects where students are asked to measure real-world motion. One purpose of this student-centered activity is to cultivate the relevance of physics in their lives. Typical project topics may include measuring the speed of a student's fastball and calculating how much reaction time batters are given. Another student may find the trajectory of her dive off the blocks at the pool and its effect on race time. Leaving the experimental design to the student's imagination allows for a variety of proposals ranging from stopwatches to highly technical video analysis. The past few years have shown an increase in students' eagerness to tackle the physics behind the motion of virtual characters and phenomena in their own video games. This paper puts forth a method of analyzing the physics behind bringing the games students are playing for enjoyment into the physics classroom.

    Urban black South African women have a high prevalence of non-communicable diseases such as obesity and type 2 diabetes. The aim of this study was to assess the physical activity patterns of a cohort of middle-aged urban-dwelling black African women and to determine if physical activity is associated with anthropometric measures and metabolic outcomes in this population. Physical activity and sitting time were assessed using the Global Physical Activity Questionnaire (GPAQ) in a cross-sectional study of 977 black African women (mean age 41.0 ± 7.84 years) from the Birth to Twenty study based in Soweto, Johannesburg. Anthropometric outcomes were measured and fasting blood glucose, insulin and lipid profile were analysed to determine metabolic disease risk and prevalence. Sixty-seven percent of the population were classified as active according to GPAQ criteria, and the domain that contributed most to overall weekly physical activity was walking for travel. Only 45.0% of women participated in leisure time activity. The prevalence of metabolic syndrome in this sample was 40.0%, and the prevalence of overweight and obesity was 29.2% and 48.0%, respectively. Women who reported owning a motor vehicle walked for travel less, and participated in more leisure-time activity (both p travel (both p travel is a major contributor to physical activity, future research should attempt to determine whether the intensity of this activity plays a role in the prevention of cardiometabolic diseases.

    Garrett, Katherine; Duda, Gintaras

    2008-04-01

    Even though there has been a tremendous amount of research done in how to help students learn physics, students are still coming away missing a crucial piece of the puzzle: why bother with physics? Students learn fundamental laws and how to calculate, but come out of a general physics course without a deep understanding of how physics has transformed the world around them. In other words, they get the ``how" but not the ``why". Studies have shown that students leave introductory physics courses almost universally less excited about the topic than when they came in. This presentation will detail an experiment to address this problem: a course weblog or ``blog" which discusses real-world applications of physics and engages students in discussion and thinking outside of class. Student response to the blog was overwhelmingly positive, with students claiming that the blog made the things we studied in the classroom come alive for them and seem much more relevant.

    Wilcox, Bethany R.; Lewandowski, H. J.

    2017-12-01

    The physics community explores and explains the physical world through a blend of theoretical and experimental studies. The future of physics as a discipline depends on training of students in both the theoretical and experimental aspects of the field. However, while student learning within lecture courses has been the subject of extensive research, lab courses remain relatively under-studied. In particular, there is little, if any, data available that address the effectiveness of physics lab courses at encouraging students to recognize the nature and importance of experimental physics within the discipline as a whole. To address this gap, we present the first large-scale, national study (Ninstitutions=75 and Nstudents=7167 ) of undergraduate physics lab courses through analysis of students' responses to a research-validated assessment designed to investigate students' beliefs about the nature of experimental physics. We find that students often enter and leave physics lab courses with ideas about experimental physics as practiced in their courses that are inconsistent with the views of practicing experimental physicists, and this trend holds at both the introductory and upper-division levels. Despite this inconsistency, we find that both introductory and upper-division students are able to accurately predict the expertlike response even in cases where their views about experimentation in their lab courses disagree. These finding have implications for the recruitment, retention, and adequate preparation of students in physics.

They cover general theoretical aspects of black hole astrophysics, the theory of accretion and ejection of gas and jets, stellar-sized black holes observed in the Milky Way, the formation and evolution of supermassive black holes in galactic centers and quasars as well as their influence on the dynamics in galactic nuclei. The final chapter addresses analytical relativity of black holes supporting theoretical understanding of the coalescence of black holes as well as being of great relevance in identifying gravitational wave signals. With its introductory chapters the book is aimed at advanced graduate and post-graduate students, but it will also be useful for specialists.

  4. The physics of the relativistic counter-streaming instability that drives mass inflation inside black holes

    If you fall into a real astronomical black hole (choosing a supermassive black hole, to make sure that the tidal forces do not get you first), then you will probably meet your fate not at a central singularity, but rather in the exponentially growing, relativistic counter-streaming instability at the inner horizon first pointed out by Poisson and Israel (1990), who called it mass inflation. The chief purpose of this paper is to present a clear exposition of the physical cause and consequence of inflation in spherical, charged black holes. Inflation acts like a particle accelerator in that it accelerates cold ingoing and outgoing streams through each other to prodigiously high energies. Inflation feeds on itself: the acceleration is powered by the gravity produced by the streaming energy. The paper: (1) uses physical arguments to develop simple approximations that follow the evolution of inflation from ignition, through inflation itself, to collapse; (2) confirms that the simple approximations capture accurately the results of fully nonlinear one- and two-fluid self-similar models; (3) demonstrates that, counter-intuitively, the smaller the accretion rate, the more rapidly inflation exponentiates; (4) shows that in single perfect fluid models, inflation occurs only if the sound speed equals the speed of light, supporting the physical idea that inflation in single fluids is driven by relativistic counter-streaming of waves; (5) shows that what happens during inflation up to the Planck curvature depends not on the distant past or future, but rather on events happening only a few hundred black hole crossing times into the past or future; (6) shows that, if quantum gravity does not intervene, then the generic end result of inflation is not a general relativistic null singularity, but rather a spacelike singularity at zero radius.

    Rosa, Katemari Diogo da

    This research focuses on the underrepresentation of minoritized groups in scientific careers. The study is an analysis of the relationships between race, gender, and those with careers in the sciences, focusing on the lived experiences of Black women physicists, as viewed through the lens of women scientists in the United States. Although the research is geographically localized, the base-line question is clear and mirrors in the researcher's own intellectual development: "How do Black women physicists describe their experiences towards the construction of a scientific identity and the pursuit of a career in physics?" Grounded on a critical race theory perspective, the study uses storytelling to analyze how these women build their identities as scientists and how they have negotiate their multiple identities within different communities in society. Findings show that social integration is a key element for Black women physicists to enter study groups, which enables access to important resources for academic success in STEM. The study has implications for physics education and policymakers. The study reveals the role of the different communities that these women are part of, and the importance of public policies targeted to increase the participation of underrepresented groups in science, especially through after-school programs and financial support through higher education.

    The physical and social environments at schools are related to students' moderate-to-vigorous physical activity (MVPA) levels. The purpose of this study was to explore the interactive effects of the school physical environment and school social capital on the MVPA of students while at school. Data from 18,875 grade 6-10 students from 331 schools who participated in the 2009/10 Canadian Health Behaviour in School-Aged Children survey were analyzed using multi-level regression. Students answered questions on the amount of time they spend in MVPA at school and on their school's social capital. Administrator reports were used to create a physical activity related physical environment score. The school physical environment score was positively associated with student MVPA at school (β = 0.040, p school social capital and MVPA was also positive (β = 0.074, p students attending schools with the lowest number of physical environment features and about 40 minutes/week for students attending schools with the lowest school social capital scores by comparison to students attending schools with the highest scores. The findings suggest that school social capital may be a more important factor in increasing students MVPA than the school physical environment. The results of this study may help inform interventions aimed at increasing student physical activity levels.

  14. Experiences that influence a student's choice on majoring in physics

    Science.gov (United States)

    Dobbin, Donya Rae

    Currently the production of college graduates with science and engineering degrees is insufficient to fill the increasing number of jobs requiring these skills. This study focuses on physics majors with an in-depth examination of student transitions from high school to college. Many different areas of influence could affect a student's decision to major in physics. The first phase of this study addresses all of the potential areas of influence identified from the literature. The goal was to identify common influences that might be used to increase students' interest in majoring in physics. Subjects (N=35) from the first phase were recruited from physics majors at diverse Michigan colleges and universities. The second phase of this study explored, in more depth, important areas of influence identified in the first phase of the study. Subjects (N=94) from the second phase were recruited from diverse colleges and universities in Indiana, Illinois, and Ohio. The interviews were also conducted via email. Approximately half of the students in the study decided to major in physics while still in high school. Their reasons relate to many of the areas of influence. For example, high school physics teachers were cited as a strong influence in many students' decisions to major in physics. Influential physics teachers were described as being helpful, encouraging and interesting. The teachers also need to be their students' number one cheerleader and not their number one critic. Some areas of influence were found to be different for males vs. females. A high percentage of all physics majors had influential adults with careers in physical or biological science fields. This percentage was even larger for female physics majors. Female students also showed a greater initial interest in astronomy than the male students. Thus, high school and college physics teachers should seek to expose students to science-related careers and adults with these careers. Astronomy is also an

    2014-12-01

    The role of autonomy in the student experience in a large-enrollment undergraduate introductory physics course was studied from a self-determination theory perspective. A correlational study investigated whether certain aspects of the student experience correlated with how autonomy supportive (versus controlling) students perceived their instructors to be. An autonomy-supportive instructor acknowledges students' perspectives and feelings and provides students with information and opportunities for choice while minimizing external pressures (e.g., incentives or deadlines). It was found that the degree to which students perceived their instructors as autonomy supportive was positively correlated with student interest and enjoyment in learning physics (β =0.31***) and negatively correlated with student anxiety about taking physics (β =-0.23**). It was also positively correlated with how autonomous (versus controlled) students' reasons for studying physics became over the duration of the course (i.e., studying physics more because they wanted to versus had to; β =0.24***). This change in autonomous reasons for studying physics was in turn positively correlated with student performance in the course (β =0.17*). Additionally, the degree to which students perceived their instructors as autonomy supportive was directly correlated with performance for those students entering the course with relatively autonomous reasons for studying physics (β =0.25**). In summary, students who perceived their instructors as more autonomy supportive tended to have a more favorable motivational, affective, and performance experience in the course. The findings of the present study are consistent with experimental studies in other contexts that argue for autonomy-supportive instructor behaviors as the cause of a more favorable student experience.

    Physical inactivity is an important risk factor for chronic diseases in Western societies. To determine the sociodemographic and motivational factors associated with physical activity in college students. The International Physical Activity Questionnaire (IPAQ) -short form- and the "motives for physical activities measure-revised" (MPAM-R) questionnaire were applied to 900 university students aged 20 ± 3 years (60% women). The frequency, level and motivations for engaging in physical activity and associated demographic factors were analyzed. Twenty two percent of students were classified as having a high level of physical activity, 54.8% had a low level and 13.9% were considered inactive. According to MET consumption, 68.9% of students are inactive and only 16.8% of students classified as very active. Ninety two percent of active students performed physical activity for health reasons. A significant association between gender and social motivation was observed. A high prevalence of physical inactivity was found in these students. Males showed higher levels of physical activity than females.

    Over the last decade, science education researchers in the US have studied students' beliefs about science and learning science and measured how these beliefs change in response to classroom instruction in science. In this paper, we present an Arabic version of the Colorado Learning Attitudes about Science Survey (CLASS) which was developed to measure students' beliefs about physics at King Saud University (KSU) in Riyadh, Saudi Arabia. We describe the translation process, which included review by four experts in physics and science education and ten student interviews to ensure that the statements remained valid after translation. We have administered the Arabic CLASS to over 300 students in introductory physics courses at KSU's men's and women's campuses. We present a summary of students' beliefs about physics at KSU and compare these results to similar students in the US.

    2017-11-01

    This case study explores students' physics-related personal epistemologies in school science practices. The school science practices of nine eleventh grade students in a physics class were audio-taped over 6 weeks. The students were also interviewed to find out their ideas on the nature of scientific knowledge after each activity. Analysis of transcripts yielded several epistemological resources that students activated in their school science practice. The findings show that there is inconsistency between students' definitions of scientific theories and their epistemological judgments. Analysis revealed that students used several epistemological resources to decide on the accuracy of their data including accuracy via following the right procedure and accuracy via what the others find. Traditional, formulation-based, physics instruction might have led students to activate naive epistemological resources that prevent them to participate in the practice of science in ways that are more meaningful. Implications for future studies are presented.

    Ullrich-French, Sarah; Smith, Alan L; Cox, Anne E

    2011-08-01

    This study was designed to assess the link of attachment relationships with physical activity motivation. Potential mediators of this link were examined in a cross-sectional study targeting college student physical activity motivation and behaviour. Participants completed self-reports of attachment relationships (with mother, father and best friend), self-determined motivation for physical activity, physical activity behaviour and the hypothesised mediator variables of perceived competence, autonomy and relatedness. The results provide support for the mediating role of these variables in the association of father attachment with self-determined motivation. Meaningful variance in self-determined motivation for physical activity and physical activity behaviour was explained. Overall, attachment relationships appear to be relevant, albeit modestly, to physical activity motivation of college students. The findings support continued efforts to integrate attachment and motivational perspectives in the study of college student health behaviour.

    2016-09-01

    Sexually transmitted infections (STIs) and marijuana use are more prevalent in African Americans/Blacks (Blacks) than any other ethnicity in the United States. Given the significant health care costs and deleterious health correlates of using marijuana or contracting a STI, it is imperative to examine their association, especially in the vulnerable and underrepresented group of young adult Blacks. The current study examines the association between lifetime marijuana use on history of STI diagnosis in a sample of Black college students. Approximately 81% of the 213 participants were female, with approximately 81% also being 21years of age or younger. Alcohol (88%) led the prevalence of substances ever used, followed by marijuana (75%), and cigarettes (57%). When including demographic and substance use covariates, lifetime marijuana use (AOR=2.51; 95% CIs, 1.01, 6.21) and age (AOR=2.72; 95% CIs, 1.32, 5.64) were associated with history of STI. These findings will inform intervention and prevention methods used to reduce STI prevalence and marijuana use among Black young adults. Both epidemiological and biological foundations will be discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Das, C. R.; Laperashvili, L. V.; Sidharth, B. G.; Nielsen, H. B.

    2017-12-01

    In the present talk, we consider the existence of the two degenerate universal vacua: a) the first Electroweak vacuum at v = 246 GeV - “true vacuum”, and b) the second Planck scale “false vacuum” at v 2 ∼ 1018 GeV. In these vacua, we investigated the different topological defects. The main aim of this paper is an investigation of the hedgehog’s configurations as defects of the false vacuum. In the framework of the f(R) gravity, suggested by authors in their Gravi-Weak Unification model, we obtained a black hole solution, which corresponds to a “hedgehog” - global monopole, “swallowed” by a black-hole with mass ∼ 1019 GeV. These black-holes form a lattice-like structure of the vacuum at the Planck scale. Considering the results of the hedgehog lattice theory in the framework of the SU(2) Yang-Mills gauge-invariant theory with hedgehogs in the Wilson loops, we have used the critical value of temperature for the hedgehog’s confinement phase. This result gave us the possibility to conclude that there exist triplet Higgs fields which can contribute to the SM at the energy scale ≃ 104 ∼ 105 GeV. Showing a new physics at the scale 10÷100 TeV, these triplet Higgs particles can provide the stability of the EW-vacuum of the SM.

  20. Examining issues of underrepresented minority students in introductory physics

    Science.gov (United States)

    Watkins, Jessica Ellen

    In this dissertation we examine several issues related to the retention of under-represented minority students in physics and science. In the first section, we show that in calculus-based introductory physics courses, the gender gap on the FCI is diminished through the use of interactive techniques, but in lower-level introductory courses, the gap persists, similar to reports published at other institutions. We find that under-represented racial minorities perform similar to their peers with comparable academic preparation on conceptual surveys, but their average exam grades and course grades are lower. We also examine student persistence in science majors; finding a significant relationship between pedagogy in an introductory physics course and persistence in science. In the second section, we look at student end-of-semester evaluations and find that female students rate interactive teaching methods a full point lower than their male peers. Looking more deeply at student interview data, we find that female students report more social issues related to the discussions in class and both male and female students cite feeling pressure to obtain the correct answer to clicker questions. Finally, we take a look an often-cited claim for gender differences in STEM participation: cognitive differences explain achievement differences in physics. We examine specifically the role of mental rotations in physics achievement and problem-solving, viewing mental rotations as a tool that students can use on physics problems. We first look at student survey results for lower-level introductory students, finding a low, but significant correlation between performance on a mental rotations test and performance in introductory physics courses. In contrast, we did not find a significant relationship for students in the upper-level introductory course. We also examine student problem-solving interviews to investigate the role of mental rotations on introductory problems.

    The promotion of physical activity and health has become a universal challenge. The Sotkamo Physical Activity as Civil Skill Program was implemented to increase students' physical activity by promoting supportive psychological and physical school environment. The aim of this study was to evaluate the effectiveness of the school-initiated physical activity program on secondary school students' self-reported physical activity. The sample included 847 students (experimental condition school = 208, control school = 639) at the age of 12 to 14 years from northeast and central Finland. The program was conducted across 1 academic year and 2 measurement phases were carried out using self-report questionnaires in April 2011 and 2012. The findings highlighted that the program appeared to be effective as an approach to change the sharp decline in the pattern of Grade 7 students' self-reported physical activity across 1 school year. Specifically, change in the experimental condition students' self-reported physical activity was 13.4% higher compared the students in the control condition. On the basis of current findings, increased opportunities for school day physical activities have the potential to affect large number of students and are an efficient strategy for promoting regular physical activity. © 2015, American School Health Association.

    2017-11-01

    Many countries desire more students to study science subjects, although relatively few students decide to study non-compulsory physics at upper-secondary school and at university. To gain insight into students' intentions to study non-compulsory physics, a longitudinal sample (covering 2258 students across 88 secondary schools in England) was surveyed in year 8 (age 12/13) and again in year 10 (age 14/15). Predictive modelling highlighted that perceived advice, perceived utility of physics, interest in physics, self-concept beliefs (students' subjective beliefs of their current abilities and performance) and home support specifically orientated to physics were key predictors of students' intentions. Latent-transition analysis via Markov models revealed clusters of students, given these factors at years 8 and 10. Students' intentions varied across the clusters, and at year 10 even varied when accounting for the students' underlying attitudes and beliefs, highlighting that considering clusters offered additional explanatory power and insight. Regardless of whether three-cluster, four-cluster, or five-cluster models were considered, the majority of students remained in the same cluster over time; for those who transitioned clusters, more students changed clusters reflecting an increase in attitudes than changed clusters reflecting a decrease. Students in the cluster with the most positive attitudes were most likely to remain within that cluster, while students in clusters with less positive attitudes were more likely to change clusters. Overall, the cluster profiles highlighted that students' attitudes and beliefs may be more closely related than previously assumed, but that changes in their attitudes and beliefs were indeed possible.

    2016-12-01

    Interactive engagement-based (IE) physics classes have the potential to invigorate and motivate students, but students may resist or oppose the pedagogy. Understanding the major influences on student satisfaction is a key to successful implementation of such courses. In this study, we note that one of the major differences between IE and traditional physics classes lies in the interpersonal relationships between the instructor and students. Therefore, we introduce the interpersonal communication constructs of instructor credibility and facework as possible frameworks for understanding how instructors and students navigate the new space of interactions. By interpreting survey data (N =161 respondents in eight sections of an IE introductory algebra-based physics course), we found both frameworks to be useful in explaining variance in student ratings of their satisfaction in the course, although we are unable to distinguish at this point whether instructor credibility acts as a mediating variable between facework and course satisfaction.

    Brewe, Eric

    2017-01-01

    We present the analysis of student networks derived from a survey of upper division physics students. Ego networks focus on the connections that center on one person (the ego). The ego networks in this talk come from a survey that is part of an overall project focused on understanding student retention and persistence. The theory underlying this work is that social and academic integration are essential components to supporting students continued enrollment and ultimately graduation. This work uses network analysis as a way to investigate the role of social and academic interactions in retention and persistence decisions. We focus on student interactions with peers, on mentoring interactions with physics department faculty, and on engagement in physics groups and how they influence persistence. Our results, which are preliminary, will help frame the ongoing research project and identify ways in which departments can support students. This work supported by NSF grant #PHY 1344247.

The target population of this study was all male and female physical education and non-physical education university students in Rasht city of Iran. After translating the Physical Self-Description Questionnaire (PSDQ and adjusting some of the questions, the questionnaire was evaluated by the specialists in the context of validity and the reliability achieved by test-retest (Cronbach Alpha value of 0.84. We then, according to the Odineski table selected 180 physical education and non-physical education males and 190 physical education and non-physical education females opportunistically. The collected data was analyzed by 2×2 MANOVA for determine differences between genders and major. The results showed mean vector scores of physical education in the following scales: physical activity; global physical; competence; sports; strength; endurance and flexibility were significantly (p<0.05 higher than that of non-physical education major students. Also, the results shows that mean vector scores of male in the following scales: health; coordination; physical activity; body fat; global physical; competence; sports; global physical self-concept and global esteem were significantly (p<0.05 higher than female. Based on the result of our study the physical self-concept non-physical education and female is lower, than that physical education and male. The results may reflect that male and physical major education students, who usually spend more time on physical activity and sport training to have better fitness and skill oriented self concept than their counterparts.

  11. Blogging in the physics classroom: A research-based approach to shaping students' attitudes toward physics

    Duda, Gintaras; Garrett, Katherine

    2008-11-01

    Although there has been much research on how to help students learn physics, students still come away without a deep understanding of how physics has transformed the world around them and almost all leave with decreased expectations and a more negative attitude toward physics. We discuss an experiment to address this problem: a course weblog which discusses real-world applications of physics and engages students in discussion and thinking outside of class. Students' attitudes toward the value of physics and its applicability to the real-world were probed using a 26-question Likert scale survey over the course of four semesters in an introductory physics course. We found that students who did not participate in the blog generally exhibited a deterioration in attitude toward physics as seen previously. Students who read, commented, and were involved with the blog maintained their initially positive attitudes toward physics. Student response to the blog was overwhelmingly positive, with students claiming that the blog made the subjects studied in the classroom come alive for them and seem more relevant.

    To contribute to the growing understanding of U.S. black-white health disparities by examining psychosocial stress as an important contributor to physical health problems. Data are from the National Survey of American Life, an integrated national household probability sample of White Americans, African Americans, and Caribbean blacks. Regression analysis was used to assess associations between goal-striving stress and hypertension, BMI, physical health problems, and self-rated health. After accounting for sociodemographic factors and three additional stressors--personal problems, lifetime racial discrimination, and everyday racial discrimination-goal-striving stress was a significant predictor of hypertension, physical health problems, and diminished self-rated health. Ethnicity moderated the relationship; the negative association between goal-striving stress and physical health problems was strongest for Caribbean blacks. This study extends the research on goal-striving stress and adds to a growing literature documenting relationships between social processes and disease.

    This study investigates how an urban, high school physics class responded to the inclusion of a classroom set of iPads and associated applications, such as screencasting. The participatory roles of students and the expressions of their relationships to physics were examined. Findings suggest that iPad technology altered classroom norms and student relationships to include increased student agency and use of evidence. Findings also suggest that the iPad provided a connection between physics, social status, and play. Videos, observations, interviews, and survey responses were analyzed to provide insight into the nature of these changes.

  15. Superradiance energy extraction, black-hole bombs and implications for astrophysics and particle physics

    CERN Document Server

    Brito, Richard; Pani, Paolo

    2015-01-01

    This volume gives a unified picture of the multifaceted subject of superradiance, with a focus on recent developments in the field, ranging from fundamental physics to astrophysics. Superradiance is a radiation enhancement process that involves dissipative systems. With a 60 year-old history, superradiance has played a prominent role in optics, quantum mechanics and especially in relativity and astrophysics. In Einstein's General Relativity, black-hole superradiance is permitted by dissipation at the event horizon, which allows energy extraction from the vacuum, even at the classical level. When confined, this amplified radiation can give rise to strong instabilities known as "blackhole bombs'', which have applications in searches for dark matter, in physics beyond the Standard Model and in analog models of gravity. This book discusses and draws together all these fascinating aspects of superradiance.

    Aydeniz, Mehmet; Yeter-Aydeniz, Kubra

    2015-03-01

    In this study we challenged 18 undergraduate physics students to develop four written scientific arguments across four physics labs: 1) gravity-driven acceleration, 2) conservation of mechanical energy, 3) conservation of linear momentum and 4) boyle's law, in a mechanics and thermodynamics laboratory course. We evaluated quality of the written scientific arguments developed by the participants using the Claim, Evidence, Reasoning and Rebuttal (CERR) rubric. The results indicate that while students developed adequate scientific explanations that summarized the findings of their experiments, they experienced unique difficulties in using a persuasive and critical discourse in their written arguments. Students experienced the most difficulty in considering alternative explanations in formulating their written scientific arguments. We elaborate on the implications of these findings for teaching physics laboratories and assessing students' learning in physics laboratories. We especially focus on the importance of framing in helping students to appropriate the epistemic norms of science in writing scientific arguments.

    Thirty-one black medical students attending five white medical schools were seen in individual interviews of one to two hours to evaluate their perceptions of racism in their medical school education. The interviews focused on racism experienced in high school, college, and medical school. Over one half of the population experienced racism during their high school and college education, while 30 of 31 subjects reported racist experiences in their medical school education. The students reported a variety of methods of coping with racist experiences and emphasized the importance of fellow minority students, faculty, and the minority office in coping with the stresses of racist experiences. Those offering counseling services to minority students should recognize the reality of racist experiences in medical education. PMID:3612829

    Supportive relationships with adults at school are critical to student engagement in adolescence. Additional research is needed to understand how students' racial backgrounds interact with the school context to shape their perceptions of school support. This study employed multilevel, latent variable methods with a sample of Black and White students (N = 19,726, 35.8 % Black, 49.9 % male, mean age = 15.9) in 58 high schools to explore variation in perceived caring, equity, and high expectations by student race, school diversity, and socioeconomic context. The results indicated that Black students perceived less caring and equity relative to White students overall, and that equity and high expectations were lower in diverse schools for both Black and White students. Nonetheless, racial disparities were attenuated in more diverse schools. The findings point to the need for intervention to improve perceptions of school support for Black youth and for all students in lower income and more diverse schools.

    Within the general university environment, students' perceived self-efficacy has been widely studied and findings suggest it plays a role in student success. The current research adapted a self-efficacy survey, from the ``Self-Efficacy for Learning Performance'' subscale of the Motivated Learning Strategies Questionnaire and administered it to the introductory, calculus-based physics classes (N=1005) over the fall 2015 and spring 2016 semesters. This assessment measured students' self-efficacy in domains including the physics class, other science and mathematics classes, and their intended future career. The effect of gender was explored with the only significant gender difference (p self-efficacy, measured by their math and science self-efficacy, acts as a mediator for the effect of test average on self-efficacy towards the physics class domain. This mediation effect was significant for both female (p < . 01) and male students (p < . 001) however, it was more pronounced for male students.

    Shapiro, Georgy; Wobus, Fred; Zatsepin, Andrei; Akivis, Tatiana; Zhou, Feng

    2017-04-01

    This study provides an integrated analysis of exchanges of water, salt and heat between the north-western Black Sea shelf and the deep basin. Three contributing physical mechanisms are quantified, namely: Ekman drift, transport by mesoscale eddies at the edge of the NW Black Sea shelf and non-local cascading assisted by the rim current and mesoscale eddies. The semi-enclosed nature of the Black Sea together with its unique combination of an extensive shelf area in the North West and the deep central part make it sensitive to natural variations of fluxes, including the fluxes between the biologically productive shelf and predominantly anoxic deep sea. Exchanges between the shelf and deep sea play an important role in forming the balance of waters, nutrients and pollution within the coastal areas, and hence the level of human-induced eutrophication of coastal waters (MSFD Descriptor 5). In this study we analyse physical mechanisms and quantify shelf-deep sea exchange processes in the Black Sea sector using the NEMO ocean circulation model. The model is configured and optimized taking into account specific features of the Black Sea, and validated against in-situ and satellite observations. The study uses NEMO-BLS24 numerical model which is based on the NEMO codebase v3.2.1 with amendments introduced by the UK Met Office. The model has a horizontal resolution of 1/24×1/24° and a hybrid s-on-top-of-z vertical coordinate system with a total of 33 layers. The horizontal viscosity/diffusivity operator is rotated to reduce the contamination of vertical diffusion/viscosity by large values of their horizontal counterparts. The bathymetry is processed from ETOPO5 and capped to 1550m. Atmospheric forcing for the period 1989-2012 is given by the Drakkar Forcing Set v5.2. For comparison, the NCEP atmospheric forcing also used for 2005. The climatological runoff from 8 major rivers is included.

    Waitzkin, H; Magaña, H

    1997-09-01

    Stimulated by our clinical work with patients who manifest unexplained "somatoform" symptoms in the primary care setting, this article addresses a theoretical black box in our understanding of somatization: how does culture mediate severe stress to produce symptoms that cannot be explained by the presence of physical illness? Despite various problems in his explanation of hysteria, Freud broke new ground by emphasizing narratives of traumatic experiences in the development and treatment of unexplained physical symptoms. Except in anthropologically oriented cultural psychiatry, contemporary psychiatry has traveled away from a focus on narrative in the study of somatization. On the other hand, recent interest in narrative has spread across many intellectual disciplines, including the humanities and literary criticism, psychology, history, anthropology, and sociology. We operationally define narratives as attempts at storytelling that portray the interrelationships among physical symptoms and the psychologic, social, or cultural context of these symptoms. Regarding somatization and trauma, we focus on the ways that narrative integrates the cultural context with traumatic life events. In explaining the black box, we postulate that extreme stress (torture, rape, witnessing deaths of relatives, forced migration, etc.) is processed psychologically as a terrible, largely incoherent narrative of events too awful to hold in consciousness. Culture patterns the psychologic and somatic expression of the terrible narrative. Methodologically, we have developed some techniques for eliciting narratives of severe stress and somatic symptoms, which we illustrate with observations from an ongoing research project. In designing interventions to improve the care of somatizing patients, we are focusing on the creation of social situations where patients may feel empowered to express more coherent narratives of their prior traumatic experiences.

    Full Text Available [b]Objective[/b]. Scientific reports provide information concerning an insufficient level of physical activity of societies. The objective of the study is recognition of the level of physical activity among Ukrainian students, and factors which condition this activity: gender, place of residence, self-reported physical fitness, and the BMI. [b]Methods[/b]. The study was conducted in 2013 among 2,125 Ukrainian students using a long version of the International Physical Activity Questionnaire (IPAQ, supplemented with data concerning the respondents’ physical development. [b]Results[/b]. The results of the study showed that the mean total physical activity of students was 3.560 MET, and its highest percentage pertained to the area of activity in sports – 1.124 MET. Significantly higher statistically physical activity was observed among males than females. In males, the highest activity was related to participation in sports classes, while in females – engagement in household chores. It was found that males, compared to females, were significantly more physically active in such areas as occupational activity (education and sports activity, whereas females showed higher activity performing household chores. According to the place of residence, inhabitants of medium-size towns and rural areas obtained the most favourable results in activity, while the inhabitants of large cities the poorest. Self-reported physical fitness was significantly correlated with the results in physical activity obtained by the students. No relationship was found between the BMI and the level of student’s physical activity. [b]Conclusion[/b]. Considering the very large population of respondents, the results obtained may be considered as an up-to-date pattern of physical activity among Ukrainian students.

    This study examines students' reasoning surrounding seemingly contradictory Likert-scale responses within five items in the Colorado Learning Attitudes About Science Survey for Experimental Physics (E-CLASS). We administered the E-CLASS with embedded open-ended prompts, which asked students to provide explanations after making a Likert-scale selection. The quantitative scores on those items showed that our sample of the 216 students enrolled in first year and beyond first year physics courses demonstrated the same trends as previous national data. A qualitative analysis of students' open-ended responses was used to examine common reasoning patterns related to particular Likert-scale responses. When explaining responses to items regarding the role of experiments in confirming known results and also contributing to the growth of scientific knowledge, a common reasoning pattern suggested that confirming known results in a classroom experiment can help with understanding concepts. Thus, physics experiments contribute to students' personal scientific knowledge growth, while also confirming widely known results. Many students agreed that having correct formatting and making well-reasoned conclusions are the main goal for communicating experimental results. Students who focused on sections and formatting emphasized how it enables clear and efficient communication. However, very few students discussed the link between well-reasoned conclusions and effective scientific communication. Lastly, many students argued it was possible to complete experiments without understanding equations and physics concepts. The most common justification was that they could simply follow instructions to finish the lab without understanding. The findings suggest several implications for teaching physics laboratory courses, for example, incorporating some lab activities with outcomes that are unknown to the students might have a significant impact on students' understanding of experiments as an

  1. Investigating Student Connections Between Mathematics and Thermal Physics

    Thompson, John R.

    2006-12-01

    As part of work on teaching and learning in upper-level undergraduate thermal physics courses, we are exploring student functional understanding of mathematical concepts required for productive reasoning about thermal and statistical physics. We find evidence that students do not make connections between the physical situations or processes under study and the mathematical concepts or algorithms needed for analysis of the physics. Examples will be provided from integrals and path integrals in the context of P-V diagrams, and from partial derivatives in the context of material properties and the Maxwell relations. With integration, our results suggest that while students may indeed have difficulties associated with the physical concepts in question, mathematical difficulties compound the problem. In particular, some students lack a functional understanding of two fundamental concepts of integration: the Riemann sum and the Fundamental Theorem of Calculus, both of which strongly impact whether a given variable is a state function or not. With partial differentiation, we find that although students are able to take partial derivatives easily, many students have difficulty understanding the mathematical and/or physical significance of their differentiation, even after instruction. Results from research are being used to develop instructional materials to address specific difficulties. Supported in part by NSF Grant #PHY-0406764.

  11. Scaffolding vector representations for student learning inside a physics game

    Science.gov (United States)

    D'Angelo, Cynthia

    Vectors and vector addition are difficult concepts for many introductory physics students and traditional instruction does not usually sufficiently address these difficulties. Vectors play a major role in most topics in introductory physics and without a complete understanding of them many students are unable to make sense of the physics topics covered in their classes. Video games present a unique opportunity to help students develop an intuitive understanding of motion, forces, and vectors while immersed in an enjoyable and interactive environment. This study examines two dimensions of design decisions to help students learn while playing a physics-based game. The representational complexity dimension looked at two ways of presenting dynamic information about the velocity of the game object on the screen. The scaffolding context dimension looked at two different contexts for presenting vector addition problems that were related to the game. While all students made significant learning games from the pre to the post test, there were virtually no differences between students along the representational complexity dimension and small differences between students along the scaffolding context dimension. A context that directly connects to students' game playing experience was in most cases more productive to learning than an abstract context.

    2018-01-30

    This study examined associations between students' physical fitness and physical activity (PA), as well as what specific physical fitness components were more significant correlates to being physically active in different settings for boys and girls. A total of 265 fifth-grade students with an average age of 11 voluntarily participated in this study. The students' physical fitness was assessed using four FitnessGram tests, including Progressive Aerobic Cardiovascular Endurance Run (PACER), curl-up, push-up, and trunk lift tests. The students' daily PA was assessed in various settings using a daily PA log for 7 days. Data was analyzed with descriptive statistics, univariate analyses, and multiple R-squared liner regression methods. Performance on the four physical fitness tests was significantly associated with the PA minutes spent in physical education (PE) class and recess for the total sample and for girls, but not for boys. Performance on the four fitness tests was significantly linked to participation in sports/dances outside school and the total weekly PA minutes for the total sample, boys, and girls. Further, boys and girls who were the most physically fit spent significantly more time engaging in sports/dances and had greater total weekly PA than boys and girls who were not physically fit. In addition, the physically fit girls were more physically active in recess than girls who were not physically fit. Overall, students' performance on the four physical fitness tests was significantly associated with them being physically active during PE and in recess and engaging in sports/dances, as well as with their total weekly PA minutes, but not with their participation in non-organized physical play outside school.

    Two salient problems in adolescent development are dating violence and suicidal ideation. Theory and empirical research have supported their association in primarily cross-sectional studies. The purpose of this study is to examine the longitudinal association between physical dating violence and suicidal ideation (thoughts or plans) in a cohort of students evaluated annually from Grades 9 to 12. The sample consisted of 556 random-selected students (50.2 % males; 47.5 % White, 37.8 % Black, 11.2 % Latino) who reported dating at least once during the four assessments. Self-reported frequency of suicidal ideation, dating, and physical dating violence perpetration and victimization were assessed each spring from ninth to twelfth grade. We used generalized estimating equations modeling to predict the effects of sex, race, school grade, and physical dating perpetration and victimization on suicidal ideation. Cumulatively, one-fourth of the sample reported suicidal ideation at least once by the end of Grade 12, and approximately half reported physical dating violence. Female gender (OR = 1.7, p = 0.02), physical dating perpetration (OR = 1.54, p = 0.048), physical dating victimization (OR = 2.03, p school (OR = 1.83, p = 0.004) were significant predictors of suicidal ideation. Race was not a significant predictor among adolescents in this sample. This longitudinal study highlights the detrimental emotional effect of physical dating violence perpetration and victimization among high school students. It is important that suicide prevention programs incorporate physical dating violence education and prevention strategies starting early in high school.

    2016-06-01

    Nationally, many public universities have started to move into the online course and program market that is most often associated with for-profit institutions of higher education. Administrators in public universities make statements regarding benefits to students' desire for flexibility and profit margins related to online courses. But do students attending a large public university want to take courses online especially science courses perceived to be difficult such as freshmen-level physics courses? This study took place at a large, public, Midwestern university and involved students enrolled in the first semester of a face-to-face, flipped physics course for engineering technology majors. Statements were collected from comments about online courses made by the university's administration and students in the course. Twenty students sorted 45 statements. Two student views emerged with one rejecting online courses in general and the other primarily rejecting online math, science, and technology courses, including physics. Students' descriptions of their previous online course experiences were used to inform the analyses and to assist in describing the two views that emerged in conjunction with the distinguishing statements. Consensus among the two views is also discussed. Overall, the results indicate a potential divergence between student views and what university administrators believe students want.

  1. Adventures from Justin's Life: Engaging Your Physics Students

    Science.gov (United States)

    Ridgley, James A.; Herron, Sherry S.

    2018-03-01

    Many teachers have had students ask the proverbial question, "When will I ever use this in my life?" In the sciences, especially physics, teachers seem to battle this torrent of indifference continually. Although many areas of our students' lives can distract them from their academic pursuits, we as teachers must be introspective in order to prevent our teaching style from becoming one of our students' potential distractions. For example, a problem source with teaching physics may be an inability to successfully pique students' interest in our lessons. According to Barrett, student engagement is critical in order for learning to occur. Student engagement is so crucially important that researchers from across the globe attempt to assist teachers in the careful construction of pedagogical "hooks" whereby they can actively engage their students. A student who is not academically engaged may find little use for what is presented and may be bored stiff during the lesson. Regardless of your theoretical perspectives on learning, constructivists to traditionalists alike have no excuse to be boring, and therefore should engage their students before presenting physics concepts.

    2014-12-01

    The members of healthcare team have an important role in implementation and protection of patient's rights. Contemporary nursing entails an ethical responsibility to advocate and protect the patients' rights. This study was designed to evaluate how ready nursing students, at the end of their education, were to play the role of patient's rights advocates and to discuss ethics education in nursing. This descriptive study was performed on nursing students at Black Sea Universities in the academic year 2010-2011. Data were collected using a structured questionnaire about students' attitudes regarding patients' rights including patient's rights regulations. The association between gender and students' attitudes was analyzed using Chi-square test. The mean age of the 238 participants was 22.11 ± 1.21 years and 82.8% of them were female. The majority of the nursing students held desirable attitudes toward patient information, truth telling, and protection of patients' privacy and medical records. However, the students' views about the rights of patients to refuse treatment, children's active participation in treatment, prioritization of the quality of life in treatment, and respect for the rights of dying patients were less satisfactory. The results of this study was concerning with regard to nursing students' readiness for duties such as patient's rights advocacy. Therefore, it proposes ethics education that covers both patient's rights and the obligations of nurses to defend these rights.

    A growing body of literature indicates that physical activity can have beneficial effects on mental health. However, previous research has mainly focussed on clinical populations, and little is known about the psychological effects of physical activity in those without clinically defined disorders. The present study investigates the association between physical activity and mental health in an undergraduate university population based in the United Kingdom. One hundred students completed questionnaires measuring their levels of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS) and their physical activity regime using the Physical Activity Questionnaire (PAQ). Significant differences were observed between the low, medium and high exercise groups on the mental health scales, indicating better mental health for those who engage in more exercise. Engagement in physical activity can be an important contributory factor in the mental health of undergraduate students.

Racial and gender differences are highlighted. This study was funded by Mayo Clinic. The study's limitations were noted.

  15. Toward understanding writing to learn in physics: Investigating student writing

    Science.gov (United States)

    Demaree, Dedra

    It is received wisdom that writing in a discipline helps students learn the discipline, and millions of dollars have been committed at many universities to supporting such writing. We show that evidence for effectiveness is anecdotal, and that little data-based material informs these prejudices. This thesis begins the process of scientific study of writing in the discipline, in specific, in physics, and creates means to judge whether such writing is effective. The studies culminating in this thesis are an aggressive start to addressing these complex questions. Writing is often promoted as an activity that, when put into classrooms in specific disciplines, not only helps students learn to write in the methods of that discipline but also helps students learn content knowledge. Students at the Ohio State University are being asked to write more in introductory courses, and the Engineering schools want their students to have more writing skills for the job market. Combined with the desire of many educators to have students be able to explain the course content knowledge clearly, it would seem that writing activities would be important and useful in physics courses. However, the question of whether writing helps learning or whether students learn writing within a non-English classroom helps learning in the discipline are open to debate, and data are needed before such claims can be made. This thesis presents several studies aimed at understanding the correlation of writing and content, and tracking and characterizing student writing behaviors to see how they are impacted by writing in physics courses. It consists of four parts: summer and autumn 2005 focus on writing in introductory physics labs with and without explicit instruction, while winter and spring 2006 focus on tracking and analyzing student writing and revising behavior in Physics by Inquiry (PbI). With these related projects, we establish three main results. First, there is a need for quantitative studies of

  17. Physics learning identity of a successful student: A plot twist

    2013-01-01

    Classroom interactions provide learning opportunities for understanding others and developing agency in a community of learners. Student learning identities were measured using a survey instrument targeting physics learning self-efficacy, expectations of classroom roles, and attitude toward social learning as components of physics learning identity. From a selection of students who scored relatively high or low on the survey sub scales, an academically successful student in an introductory physics course using an active engagement curriculum was selected to examine identity development. Findings indicate he didn't develop a sense of agency, nor did he feel a need to alter his participation, although there were ample opportunities to do so in the learning community. These results suggest that being a successful physics student in the traditional sense doesn't necessarily mean the student is successful at adopting meta-goals which are the non-content course goals of learning to think like a physicist. This student was prompted to engage meaningfully but didn't feel it was required for success which suggests that structural alignment is required to motivate students to achieve meta-goals.

    We report the results of a study on students' interest in physics at the end of their compulsory schooling in Israel carried out in the framework of the ROSE Project. Factors studied were their opinions about science classes, their out-of-school experiences in physics, and their attitudes toward science and technology. Students' overall interest in physics was "neutral" (neither positive nor negative), with boys showing a higher interest than girls. We found a strong correlation between students' "neutral" interest in physics and their negative opinions about science classes. These findings raise serious questions about the implementation of changes made in the Israeli science curriculum in primary and junior high school, especially if the goal is to prepare the young generation for life in a scientific-technological era. A more in-depth analysis of the results led us to formulate curricular, behavioral, and organizational changes needed to reach this goal.

    Full Text Available Background: During lectures, usually students sit in an awkward position, for prolonged period of time and that may cause postural instability. For a good posture, bilateral landmarks should be on same level, when viewed from front or behind. Therefore, both shoulders should also be on same level as well. Any alteration in level of shoulders in healthy individual may lead to deformity in spine or extremity. The objective of this study was to analyze the level of both shoulders in the physical therapy students and to find its correlation with the perception of students about their shoulder balance. Methods: An observational (cross – sectional study was conducted on students of Doctor in Physical Therapy (DPT from colleges of Physical Therapy, Karachi. 100 Students were selected by Simple Random Sampling technique. Data from students was collected by administering a questionnaire. It includes close-ended questions. Afterwards, the level of both shoulders of the students, were assessed by using Scoliosis Meter. Results: Response from students showed that 79% of them assumed that both shoulders are in same level. When level of shoulder of students was assessed by scoliosis meter, it showed that 37% students have absolute level shoulder. Spearman’s Correlation coefficient (r = 0.046, p= 0.65 showed a weak, positive correlation between perception of the students about shoulder level and assessment of shoulder tilt. Conclusion: This showed that the perception of students about level of both shoulders was not correlated to the actual levels of the shoulders. Hence, as they were not assuming it uneven, so they may not pay any attention to keep themselves straight.

    In this research we asked the fourth year students (N = 50) of a technical faculty of the University of Split (Republic of Croatia) to solve a partially specified physics problem related to gravitational force. The task for the students was to decide whether the situation described in the problem is feasible or not. Nevertheless, the formulation of the problem is such that it does not give students any explicit advice regarding what to calculate or how to judge the feasibility of the given situation in the real world. The research was carried out using a structured written exam method. The worksheet was structured in order to assess explicitly a few elements of the students' problem-solving performance. Based on their results, the examinees were classified into four categories, depending on what they could or could not accomplish during problem solving. A majority of students were not able to solve the given physical problem completely. A selection of students' and professors' observations is also included. Our results show that traditionally formulated numerical exercises, which are mostly used in physics teaching, do not develop students' abilities in higher-order thinking (i.e. planning, decision making or result evaluation) to a desirable extent. We suggest that partially specified problems should be given to students, both in problem-solving sessions and exams, in order to prepare them for dealing with ill-structured tasks in real life.

    Full Text Available South African government has been promulgating pieces of legislation aimed at ensuring racial integration, especially in higher education, and indirectly enforcing acculturation in historically white universities. Studies have proven that institutional cultures in historically white universities alienate and exclude black students’ identities. These students’ sense of social identity, which includes culture, heritage, language and traditions, and consequently self-esteem and self-concept, is altered in these institutions. Research has been scant regarding the shape and form that black students’ identity assumes when they get to these spaces. Using Tajfel and Turner’s (1979 social identity theory and Berry’s (2005 theory of acculturation, this article explores the experiences of black students in negotiating their social identities in historically white universities. Evoking Steve Biko’s analysis of ‘artificial integration’ (1986, we hope to illustrate how the ‘integration’ narrative sought to discard the identity of black students and psychologically enforce a simulation of black students into white-established identities. The study has implications for policy development as we hope to sensitise theoretically the historically white universities to, apart from mere opening of spaces of learning, understand the social identity challenges of black students in these institutions.

    This study aimed to examine whether intrinsic motivation and behavioral self-regulation are related to physical activity during middle school. Structural equation modeling was applied in cross-sectional and longitudinal tests of self-determination theory. Consistent with theory, hypothesized relations among variables were supported. Integrated regulation and intrinsic motivation were most strongly correlated with moderate-to-vigorous physical activity measured by an accelerometer. Results were independent of a measure of biological maturity. Construct validity and equivalence of measures were confirmed longitudinally between the sixth and seventh grades and between boys and girls, non-Hispanic Black and White children and overweight and normal-weight students. Measures of autonomous motivation (identified, integrated, and intrinsic) were more strongly related to physical activity in the seventh grade than measures of controlled motivation (external and introjected), implying that physical activity became more intrinsically motivating for some girls and boys as they moved through middle school. Nonetheless, change in introjected regulation was related to change in physical activity in the seventh grade, suggesting that internalized social pressures, which can be detrimental to sustained activity and well-being, also became motivating. These results encourage longer prospective studies during childhood and adolescence to clarify how controlled and autonomous motivations for physical activity develop and whether they respond to interventions designed to increase physical activity.

    Bringing up the young people who are seen as the guaranty of the future depends on a better education. One of the best ways of forming a high in quality education is connected to developing the quality in teacher training. Most of the developed countries have been carrying on studies in order to develop teacher training. School experience classes are the ones which are planned for the candidate teachers to observe the school in learning and teaching period and to practice in classrooms. Beginning from candidate teachers first years at school, this class should be thought to be beneficial for identifying their future school atmosphere, and it should be run effectively. For this purpose, it has been identified what difficulties the physics undergraduate and physics (with no thesis) master students, who took part in School Experience classes at the practice schools of Konya at which faculty-school cooperation is applied, had during activities, and their success at overcoming these difficulties, and their ideas about the practice school and its teachers. The research was done by making a survey to the physics undergraduate and physics(with no thesis) master students in 2003 Spring semester. The results of the research were analyzed for both girls and boys separately. After analyzed, the results showed that the most striking activity which both the undergraduate physics and physics(with no thesis) master students had difficulty was group activities. Moreover, it showed that 90 percent of the two groups had the idea that school experience activities would be beneficial for being a good physics teacher. It has been also recognized that the physics undergraduate students had a more positive view than physics(with no thesis) master students on the matter of meeting lack of interest from practice teachers, and taking the same course from the same teacher

    Researchers have found that children with dyslexia reason differently with respect to language from those who do not have dyslexia. Dyslexic students' brains work differently than do students without dyslexia. Some researchers speculate that these differences provide dyslexic students with an advantage in science. The presentation will describe an outreach activity which developed and delivered instructional modules in physics to students in grades kindergarten through sixth. These modules were tested on thirty students who attended a summer camp designed for students who have been diagnosed with dyslexia. Eighty percent of students who have learning disabilities have dyslexia. Many of the students who attended this camp have experienced repeated failure in the traditional school system, which emphasizes literacy with little attention to science. A number of science and engineering professors collaborated with this camp to build instructional modules that were delivered one hour per day, during two weeks of this five week summer camp (ten hours of hands-on physics instruction). Both quantitative and qualitative data were collected with respect to the impact that this camp had on students' understanding and interests in science. The results of these efforts will be presented.

    Society is constantly in flux, which demands the continuous development of our educational system to meet new challenges and impart the appropriate knowledge/skills to students. In order to improve student learning, among other things, the way we are teaching has significantly changed over the past few decades. We are moving away from traditional, lecture-based teaching towards more interactive, engagement-based strategies. A current, major challenge for universities is to increase student retention. While students' academic and social integration into an institution seems to be vital for student retention, research on the effect of interpersonal interactions is rare. I use of network analysis to investigate academic and social experiences of students in and beyond the classroom. In particular, there is a compelling case that transformed physics classes, such as Modeling Instruction (MI), promote persistence by the creation of learning communities that support the integration of students into the university. I will discuss recent results on pattern development in networks of MI students' interactions throughout the semester, as well as the effect of students' position within the network on their persistence in physics.

    2016-06-01

    Student learning in instructional physics labs represents a growing area of research that includes investigations of students' beliefs and expectations about the nature of experimental physics. To directly probe students' epistemologies about experimental physics and support broader lab transformation efforts at the University of Colorado Boulder and elsewhere, we developed the Colorado Learning Attitudes about Science Survey for experimental physics (E-CLASS). Previous work with this assessment has included establishing the accuracy and clarity of the instrument through student interviews and preliminary testing. Several years of data collection at multiple institutions has resulted in a growing national data set of student responses. Here, we report on results of the analysis of these data to investigate the statistical validity and reliability of the E-CLASS as a measure of students' epistemologies for a broad student population. We find that the E-CLASS demonstrates an acceptable level of both validity and reliability on measures of item and test discrimination, test-retest reliability, partial-sample reliability, internal consistency, concurrent validity, and convergent validity. We also examine students' responses using principal component analysis and find that, as expected, the E-CLASS does not exhibit strong factors (a.k.a. categories).

    Full Text Available In order to determine physical fitness differences in students with different cardiorespiratory endurance levels, a study was conducted on a sample of students of the Faculty of Sport and Physical Education at the University of Nis. The sample was divided into two subsamples, where the first subsample comprised 27 female students and the other 35 male students. Physical fitness was assessed using eight tests from the Eurofit battery of tests: the single-leg balance test - for the assessment of general balance, plate tapping - for the assessment of speed of movement, sit-and-reach - for the assessment of flexibility, the standing broad jump - for the assessment of explosive strength, the handgrip test - for the assessment of static strength, sit-ups - for the assessment of repetitive trunk strength, the bent arm hang - for the assessment of muscular endurance and the 10x5 meter shuttle run - for the assessment of the speed/agility. Cardiorespiratory endurance was estimated with the aid of 20 m endurance shuttle-run test. Based on the level of cardiorespiratory endurance, the participants in each subsample, were divided into three groups using a cluster analysis: high (VKRI, average (PKRI and low level (NKRI. The physical fitness differences of students with different cardiorespiratory endurance levels were calculated using the one-way analysis of variance. The results showed that there were no differences in physical fitness of students with different cardiorespiratory endurance levels. Based on the results it can be concluded that the level of cardiorespiratory endurance does not affect the components of physical fitness among students of both sexes.

  19. Supporting students in building interdisciplinary connections across physics and biology

    2014-03-01

    Our research team has been engaged in the iterative redesign of an Introductory Physics course for Life Science (IPLS) majors to explicitly bridge biology and physics in ways that are authentic to the disciplines. Our interdisciplinary course provides students opportunities to examine how modeling decisions (e.g. knowing when and how to use different concepts, identifying implicit assumptions, making and justifying assumptions) may differ depending on canonical disciplinary aims and interests. Our focus on developing students' interdisciplinary reasoning skills requires 1) shifting course topics to focus on core ideas that span the disciplines, 2) shifting epistemological expectations, and 3) foregrounding typically tacit disciplinary assumptions. In working to build an authentic interdisciplinary course that bridges physics and biology, we pay careful attention to supporting students in constructing these bridges. This course has been shown to have important impacts: a) students seek meaningful connections between the disciplines, b) students perceive relevance and utility of ideas from different disciplines, and c) students reconcile challenging disciplinary ideas. Although our focus has been on building interdisciplinary coherence, we have succeeded in maintaining strong student learning gains on fundamental physics concepts and allowed students to deepen their understanding of challenging concepts in thermodynamics. This presentation will describe the shifts in course content and the modern pedagogical approaches that have been integrated into the course, and provide an overview of key research results from this project. These results may aid physicists in reconsidering how they can meaningfully reach life-science students.

  3. Assessing college students' retention and transfer from calculus to physics

    Science.gov (United States)

    Cui, Lili

    Many introductory calculus-based physics students have difficulties when solving physics problems involving calculus. This study investigates students' retention and transfer from calculus to physics. While retention is the ability to recall your knowledge at a later point in time, transfer of learning is defined as the ability to apply what one has learned in one situation to a different situation. In this dissertation we propose a theoretical framework to assess students' transfer of learning in the context of problem solving. We define two kinds of transfer---horizontal transfer and vertical transfer. Horizontal transfer involves applying previously learned ideas in a problem. Vertical transfer involves constructing new ideas to solve the problem. Students need to employ both horizontal and vertical transfer when they solve any problem. This framework evolves through this research and provides a lens that enables us to examine horizontal and vertical transfer. Additionally, this proposed framework offers researchers a vocabulary to describe and assess transfer of learning in any problem solving context. We use a combination of qualitative and quantitative methods to examine transfer in the context of problem solving. The participants in this study were students enrolled in a second-semester physics course taken by future engineers and physicists, calculus instructors and physics instructors. A total of 416 students' exam sheets were collected and reviewed. Statistical methods were used to analyze the quantitative data. A total of 28 students and nine instructors were interviewed. The video and audio recordings were transcribed and analyzed in light of the aforementioned theoretical framework. A major finding from this study is that a majority of students possess the requisite calculus skills, yet have several difficulties in applying them in the context of physics. These difficulties included: deciding the appropriate variable and limits of integration; not

    To describe relationships among physical activity (PA), physiological factors, and psychological factors in Black women with type 2 diabetes mellitus (T2DM). A cross-sectional design was used (N = 109). Data were collected on PA(activity/inactivity, TV hours, bed confinement), physiology (blood pressure, lipids, hemoglobin A1c), psychology (anxiety,emotional distress, physical functioning, bodily pain, vitality), and health care provider (HCP) support. Walking was the preferred PA; TV viewing averaged 3.7 hours/day, and 24% reported confinement to bed >1 week in the last year. Inactive women had greater physiological and psychological problems than active women. Women watching TV >2 hours/day had more physiological problems than women watching TV Women reporting >1 week of confinement to bed in the last year had more physiological and psychological problems than those confined to bed women with T2DM should promote walking, address TV viewing time, incorporate HCP’s role of PA counseling/support,and address several psychological factors.

    2013-06-01

    It has been established by physics education researchers that there is a correlation between the learner’s behavior, their epistemological beliefs with which they come to the classrooms, and their success in a course. This study of Indian students and teachers explores expectations and beliefs in learning physics at the secondary and tertiary levels by making use of the Maryland Physics Expectation (MPEX) survey, which has been tested for both its validity and its reliability. The MPEX was administered to a sample of 265 Indian students at three different levels of study: (i) XII standard (high school), (ii) undergraduate (Bachelor of Science), and (iii) master’s degree (Master of Science in Physics, MS). In India, a pre-post instruction difference between the attitudes of class XII, undergraduate, and master’s students is observed with favorable improvement in master’s students as compared to deterioration in both class XII and undergraduate students. A comparison of these results with those reported in similar studies conducted in four other countries (U.S., Turkey, Philippines, and Thailand) indicates that there is a difference between the U.S. students and those of the other three countries and also between U.S. experts and Indian teachers. In all countries (U.S., India, Turkey, Thailand, and Philippines) the basic trend of expectation from pre to post test remained the same—there was a deterioration observed in all levels of students. Indian MS students were an exception. A significant difference was observed in the expectations of U.S. experts and Indian teachers. The score of favorable views of Indian class XII and undergraduate students was observed to be less than U.S. students in many clusters.

    Background: This paper presents a case study from a physics course at a Norwegian university college, investigating key aspects of a group-work project, so-called learning labs, from the participating students' perspective. Purpose: In order to develop these learning labs further, the students' perspective is important. Which aspects are essential for how the students experience the learning labs, and how do these aspects relate to the emergence of occurrences termed joint workspace, i.e. the maintenance of content-related dialogues within the group? Programme description: First year mechanical engineering students attended the learning labs as a compulsory part of the physics course. The student groups were instructed to solve physics problems using the interactive whiteboard and then submit their work as whiteboard files. Sample: One group of five male students was followed during their work in these learning labs through one term. Design and methods: Data were collected as video recordings and fieldwork observation. In this paper, a focus group interview with the students was the main source of analysis. The interpretations of the interview data were compared with the video material and the fieldwork observations. Results: The results show that the students' overall experience with the learning labs was positive. They did, however, point to internal aspects of conflicting common and personal goals, which led to a group-work dynamics that seemed to inhibit elaborate discussions and collaboration. The students also pointed to external aspects, such as a close temporal proximity between lectures and exercises, which also seemed to inhibit occurrences termed joint workspace. Conclusions: In order to increase the likelihood of a joint workspace throughout the term in the learning labs, careful considerations have to be made with regard to timing between lectures and exercises, but also with regard to raising the students' awareness about shared and personal goals.

    Full Text Available Because the development of healthy bodies during the years of growth has life-long health consequences, it is important to understand the early influences of diet and physical activity (PA. One way to generate hypotheses concerning such influences is to conduct cross-sectional studies of how diet and PA are related to different components of body composition. The subjects were 660 black and white adolescents. Total body bone mineral content (BMC was measured with dual-energy X-ray absorptiometry; free-living diet and PA were assessed with 4-7 separate 24-h recalls. The main dietary variables investigated were: total energy intake, macronutrient distribution (%, dairy servings, vitamin D, and calcium. The main PA variables were hours of moderate PA (3-6 METs and vigorous PA (>6 METs. BMC was higher in blacks than in whites (P<0.01 and it increased more in boys than in girls (age by sex interaction as age increased (P<0.01. After adjustment for age, race and sex, higher levels of BMC were associated with higher levels of energy intake, dairy servings, calcium, vitamin D, and vigorous PA (all P 's<0.05. In the multivariable model, significant and independent proportions of the variance in BMC were explained by race, the age by sex interaction, calcium, and vigorous PA (all P 's<0.01. When height was used as the outcome variable, similar diet results were obtained; however, there was a sex by vigorous PA interaction, such that vigorous PA was associated with height only in the girls. These data are consistent with the hypothesis that the bone mass and height of growing youths are positively influenced by higher dietary intake of energy and dairy foods, along with sufficient amounts of vigorous PA. This hypothesis needs to be tested in randomized controlled trials.

    Informal education programs organized by university physics departments are a popular means of reaching out to communities and satisfying grant requirements. The outcomes of these programs are often described in terms of broader impacts on the community. Comparatively little attention, however, has been paid to the influence of such programs on those students facilitating the informal science programs. Through Partnerships for Informal Science Education in the Community (PISEC) at the University of Colorado Boulder, undergraduate and graduate physics students coach elementary and middle school children during an inquiry-based science afterschool program. As part of their participation in PISEC, university students complete preparation in pedagogy, communication and diversity, engage with children on a weekly basis and provide regular feedback about the program. We present findings that indicate these experiences improve the ability of university students to communicate in everyday language and positively influence their perspectives on teaching and learning.

    2010-10-01

    Over the past 30 years, physics education research has guided the development of instructional strategies that can significantly enhance students' functional understanding of concepts in introductory physics. Recently, attention has shifted to instructional goals that, while widely shared by teachers of physics, are often more implicit than explicit in our courses. These goals involve the expectations and attitudes that students have about what it means to learn and understand physics, together with the behaviors and actions students think they should engage in to accomplish this learning. Research has shown that these ``hidden'' elements of the curriculum are remarkably resistant to instruction. In fact, traditional physics courses tend to produce movement away from expert-like behaviors. At Western Washington University, we are exploring ways of promoting metacognition, an aspect of the hidden curriculum that involves the conscious monitoring of one's own thinking and learning. We have found that making this reflective thinking an explicit part of the course may not be enough: adequate framing and scaffolding may be necessary for students to meaningfully engage in metacognition. We have thus taken the basic approach of developing metacognition, like conceptual understanding, through guided inquiry. During our teaching experiments, we have collected written and video data, with twin goals of guiding iterative modifications to the instruction as well as contributing to the knowledge base about student metacognition in introductory physics. This talk will provide examples of metacognition activities from course assignments and labs, and will present written data to assess the effectiveness of instruction and to illustrate specific modes of students' reflective thinking.

    The main purposes of this study were to identify Taiwanese university students' physics learning profiles in terms of their critical conceptions of learning physics and to compare their physics learning self-efficacy with the different learning profiles. A total of 250 Taiwanese undergraduates who were majoring in physics participated in this study and were invited to complete two instruments, physics learning profile and physics learning self-efficacy (PLSE). The main results indicated that, first, the two instruments developed in this study had satisfactory validity and reliability. Second, three fundamental physics learning profiles, the reproductive, transitional, and constructive profiles, were characterized based on the cluster analysis. It is also evident that the three learning profiles demonstrated different levels of self-efficacy for the five PLSE dimensions. The students with a reproductive profile tended to possess the lowest PLSE across the five dimensions. The students with a transitional profile may possess higher confidence in higher-order cognitive skills and laboratory activities than those with a reproductive profile. However, only those with a constructive profile, highlighting a comprehensive understanding of physics knowledge/concepts as well as de-emphasizing physics learning as preparing for tests and calculating and practising tutorial problems, possessed stronger PLSE in applying what they learned to real-world contexts as well as in scientifically communicating with others.

    Individuals experiencing a highly caring, task-involving, and low ego-involving exercise climate have reported greater ownership in exercise class and empowerment to exercise in general. This study examined the relationship between ownership and empowerment in exercise, with 2 context-specific outcomes, satisfaction with physical education (PE) and physical activity, respectively. Given the mission of PE to foster individuals' lifelong physical activity habit, the perceptions of high school students were collected for this study. Ownership in exercise was hypothesized to be significantly, positively correlated with students reporting satisfaction in PE more than their satisfaction in physical activity, whereas empowerment in exercise was hypothesized to be more strongly, positively correlated with students' physical activity satisfaction. A second purpose of this study was to test the measurement quality of the updated Empowerment in Exercise Scale (EES; now 13 items). High school students (N = 502, 43% female) in a Midwestern U.S. school district completed a survey. Confirmatory factor analysis supported the internal measurement structure of the EES (λ = .62-.91; McDonald's omega = .89) across student gender (strong invariance). Additionally, the structural equation modeling analysis revealed only 1 parameter moderated by the students' gender (latent mean of ownership). The hypotheses were supported, such that ownership in exercise was more strongly correlated with PE satisfaction (r = .87) and empowerment in exercise had a stronger correlation with physical activity satisfaction (r = .92). These results support the beneficial effect a satisfying experience in PE can have on students' satisfaction with physical activity outside of school.

    2012-02-01

    Although memorizing formulae and learning how to perform calculations is crucial for acquiring a working knowledge of physical theories, the standard pedagogical method employed by many textbooks does not prepare the student to become a practicing scientist precisely because it tends to mask the actual scientific method: the science is presented as an accomplished fact; the prescribed questions revolve largely around technological applications of accepted laws. In this talk, I will describe a two-year general physics curriculum which I have developed and taught for the past decade to undergraduate students at Wisconsin Lutheran College. The curriculum is unique in that it provides students of the natural and mathematical sciences with a comprehensive introduction to physics based on the careful reading and analysis of selections from foundational texts in physics and astronomy. The curriculum is designed to encourage a critical and circumspect approach to the study of natural science, while at the same time developing a suitable foundation for advanced coursework in physics. Through the careful reading and analysis of foundational scientific texts, students learn skills which are essential when considering the practical and philosophical implications of scientific theories.

  20. A Framework for Understanding Physics Students' Computational Modeling Practices

    Science.gov (United States)

    Lunk, Brandon Robert

    With the growing push to include computational modeling in the physics classroom, we are faced with the need to better understand students' computational modeling practices. While existing research on programming comprehension explores how novices and experts generate programming algorithms, little of this discusses how domain content knowledge, and physics knowledge in particular, can influence students' programming practices. In an effort to better understand this issue, I have developed a framework for modeling these practices based on a resource stance towards student knowledge. A resource framework models knowledge as the activation of vast networks of elements called "resources." Much like neurons in the brain, resources that become active can trigger cascading events of activation throughout the broader network. This model emphasizes the connectivity between knowledge elements and provides a description of students' knowledge base. Together with resources resources, the concepts of "epistemic games" and "frames" provide a means for addressing the interaction between content knowledge and practices. Although this framework has generally been limited to describing conceptual and mathematical understanding, it also provides a means for addressing students' programming practices. In this dissertation, I will demonstrate this facet of a resource framework as well as fill in an important missing piece: a set of epistemic games that can describe students' computational modeling strategies. The development of this theoretical framework emerged from the analysis of video data of students generating computational models during the laboratory component of a Matter & Interactions: Modern Mechanics course. Student participants across two semesters were recorded as they worked in groups to fix pre-written computational models that were initially missing key lines of code. Analysis of this video data showed that the students' programming practices were highly influenced by

One measured length and mass of the body, registered cardiorespiratory indexes – cardiac rate at peace and after 20 squats, vital capacity of lungs, breath-holding on inhalation and exhalation. The coefficient of physical development was calculated on a formula taking into account actual and middling population indexes. Gradual development of morphofunctional indexes is set for pupils and students from 7 to 20 years old. Rates of such changes were different both in age-old and sexual groups. It is educed that for boys and girls 7-8 years middling the statistical values of coefficient of physical development exceeded standard indexes. In 9-13 years on a background of further increase of morphofunctional parameters the rates of increase of physical development diminished a bit. From 13 to 16 years the index of coefficient of physical development changed a little, except for an insignificant increase in 14 years. It is shown that in an age-old period 17-20 years a mesosomia prevails for the inspected students. It is educed reliable differences between the values of coefficient of physical development in the groups of boys and girls 17 and 19 years.

    There is strong evidence that suggests physical activity can enhance mental well-being. However, this relationship has not been widely investigated in student nurses. A cross-sectional study was conducted to examine the relationship between physical activity and mental well-being in undergraduate student nurses (n=215). Physical activity was measured using the International Physical Activity Questionnaire. Other outcomes included self-esteem, anxiety, depression, life satisfaction, outcome expectations and self-efficacy. Almost, a quarter (23.8%) of the total sample, were meeting the Department of Health's physical activity guideline. Mean body mass index (BMI) was 25.0 with 40% being in the overweight to morbidly obese category. Self-esteem was significantly positively correlated with total physical activity (r=0.16, p=0.038) and moderate intensity activity (r=0.17, p=0.021). No other significant relationships were found between anxiety, depression and satisfaction with life and physical activity. Outcome expectations for exercise and self-efficacy were significantly positively correlated with moderate (r=0.17, p=0.019) and vigorous (r=0.28, p=0.000) intensity activity and total physical activity (r=0.29, p=0.000). BMI was significantly positively correlated with age (r=0.242, p=0.001), significantly negatively correlated with self-efficacy for exercise (r=0.257, p=0.000) and satisfaction with life (r=-0.144, p=0.041). Regression analysis showed that low self efficacy for exercise and increasing age were significant predictors of BMI with a small effect size r(2)=0.126, adjusted r(2)=0.112. BMI and physical activity variables collectively explained only 2% of the variance for anxiety, 4% for depression, 5% for self esteem and 6% for satisfaction with life. BMI was a significant predictor of satisfaction with life (Beta=-0.171, p=0.027). Participation in physical activity may be influential in improving mental well-being in student nurses.

    This study examined the effect of using physical activity homework on physical activity levels of college students. Students in randomly assigned sections of a university health course were assigned 30 minutes of physical activity homework 3 days a week or no homework for 12 weeks. Participants completed self-reports of physical activity before the homework intervention and again at the conclusion of the 12 weeks of physical activity homework. Participants in all course sections reported significant increases in the number of days per week of moderate and vigorous physical activity. Participants in homework sections additionally showed significant increases in the days they engaged in muscular strength/endurance training and activities to manage weight. Participants in sections without homework showed a significant increase in the number of days engaged in flexibility training. Comparison of gain scores showed statistically significant increases by the homework group in the days they participated in activities designed to manage weight. Physical activity homework was deemed to be an effective method of increasing college students' levels of physical activity.

  6. Possibilities: A framework for modeling students' deductive reasoning in physics

    Science.gov (United States)

    Gaffney, Jonathan David Housley

    Students often make errors when trying to solve qualitative or conceptual physics problems, and while many successful instructional interventions have been generated to prevent such errors, the process of deduction that students use when solving physics problems has not been thoroughly studied. In an effort to better understand that reasoning process, I have developed a new framework, which is based on the mental models framework in psychology championed by P. N. Johnson-Laird. My new framework models how students search possibility space when thinking about conceptual physics problems and suggests that errors arise from failing to flesh out all possibilities. It further suggests that instructional interventions should focus on making apparent those possibilities, as well as all physical consequences those possibilities would incur. The possibilities framework emerged from the analysis of data from a unique research project specifically invented for the purpose of understanding how students use deductive reasoning. In the selection task, participants were given a physics problem along with three written possible solutions with the goal of identifying which one of the three possible solutions was correct. Each participant was also asked to identify the errors in the incorrect solutions. For the study presented in this dissertation, participants not only performed the selection task individually on four problems, but they were also placed into groups of two or three and asked to discuss with each other the reasoning they used in making their choices and attempt to reach a consensus about which solution was correct. Finally, those groups were asked to work together to perform the selection task on three new problems. The possibilities framework appropriately models the reasoning that students use, and it makes useful predictions about potentially helpful instructional interventions. The study reported in this dissertation emphasizes the useful insight the

The sample consisted of 72 students (9 to 12 years, 34 of them studying full time. The subjects answered a questionnaire about physical activity, sedentary behavior, and sociodemographic characteristics. Data regarding sexual maturation, body composition and physical fitness were also collected. The results showed that girls studying full time spent less time per day in sedentary behavior compared to part-time girls (p<0.05. Analysis of anthropometric variables showed a significantly lower body fat percentage in boys studying full time. With respect to the physical fitness tests, significant differences were identified in the sit and reach test, horizontal jump, medicine ball throw and agility, with the observation of higher performance in full-time students. Similarly, girls studying full time exhibited significantly higher performance in the horizontal jump and agility tests compared to their peers. It can be concluded that full-time students spend less time in sedentary behavior and exhibit better physical fitness indices in most of the tests used, irrespective of gender.

    Burnley, P. C.; Thomas, S.; Honn, D. K.

    2011-12-01

    We are assembling a group of web-based educational modules for a course entitled "Introduction to Mineral Physics". Although the modules are designed to function as part of a full semester course, each module will also be able to stand alone. The modules are targeted at entry level graduate students and advanced undergraduate students. Learning outcomes for the course are being developed in consultation with educators throughout the mineral physics community. Potential users include mineral physicists teaching "bricks and mortar" graduate classes at their own institutions, mineral physicists teaching graduate classes in a distance education setting, mineralogy teachers interested in including supplementary material in their undergraduate mineralogy class, undergraduates doing independent study projects and graduate students and colleagues in other subdisciplines who wish to brush up on mineral physics topics. The modules reside on the Science Education Resource Center at Carleton College web site in the On the Cutting Edge - Teaching Mineralogy collection. Links to the materials will be posted on the Consortium for Materials Properties Research in Earth Sciences website. The modules will be piloted in a graduate level distance education course in mineral physics taught from UNLV during the spring 2012 semester. This course and others like it can address the current problems faced by faculty in state universities where rising minimum enrollments are making it difficult to teach a suitable graduate course to incoming students.

    The present study aimed at investigation of the relationship between physiological features of cardiorespiratory system of a group of athletes with individually-typological charac-teristics of the organism (age, type of constitution, sports experience, the degree of adaptation) to physical activities on the basis of a comprehensive study of the cardiorespiratory system. The study was conducted on 450 students from 18 to 24 years of age from Kazakhstan, Russia, India, and Pakistan to evaluate the influence of physical culture and sports on the formation of a healthy lifestyle of young people in higher education institutions. The students were divided into groups - the first group - student 18-20 years of age; the second group - students 21-24 years of age; the control group included students of the same age not actively involved in sports (2 lessons of physical training per week). The relationship between physiological features of cardiorespiratory system of athletes and individually-typological characteristics of the organism (age, type of constitution, sports experience, the degree of adaptation) was determined.

  20. Investigating and accounting for physics graduate students' tutorial classroom practice

    Science.gov (United States)

    Goertzen, Renee Michelle

    Physics Education researchers have been working to understanding how students learn physics, which has led to the creation of a body of research-based curricula. It is equally important to study novice instructors, graduate teaching assistants (TAs), who often teach these students. The study of TAs has similarities to how students have been studied: it is important to identify what preconceptions they often enter the classroom with, what resources they may have that they could apply to their physics teaching, and how both the classroom environment and past experiences affect what they are doing in the classroom. Although TAs are responsible for a significant portion of students' instruction at many universities, science TAs and their teaching have not been the focus of any significant amount of study. This dissertation begins to fill this gap by examining physics graduate students who teach discussion sections for introductory courses using tutorials, which are guided worksheets completed by groups of students. While assisting students with their conceptual understanding of physics, TAs are also expected to convey classroom norms of constructing arguments and listening and responding to the reasoning of others. Physics graduate students enter into the role of tutorial TA having relative content expertise but minimal or no pedagogical expertise. This analysis contends that considering the broader influences on TAs can account for TA behavior. Observations from two institutions (University of Colorado, Boulder and University of Maryland, College Park) show that TAs have different valuations (or buy-in) of the tutorials they teach, which have specific, identifiable consequences in the classroom. These differences can be explained by differences in the TAs' different teaching environments. Next, I examine cases of a behavior shared by three TAs, in which they focus on relatively superficial indicators of knowledge. Because the beliefs that underlie their teaching

    Extant studies indicate persons with autism have difficulties in social interaction, verbal and nonverbal communication, repetitive behaviors, and poor ability to generalize learned skills. Obesity has also been identified as significantly affecting children with autism spectrum disorders (ASD). Negative experience in physical education (PE) may be the antecedent behavior to lack of activities that are mediators to sedentary lifestyles and contributors to the chronic illnesses associated with overweight and obesity. Students with ASD often cannot perform required activities to meet required PE standards. It is imperative school nurses be aware of the many challenges students with ASD bring into a PE class. School nurses provide education for the members of the school community, including the Individualized Education Plan team, regarding the need for attention to limitations, including physical activity, of students with ASD. © The Author(s) 2013.

    To feasibility test a 12-week church-based physical activity intervention that was culturally sensitive, age- and gender specific directed at changing attitudes of Black adolescent girls' to be more physically active. A one-group pre- and posttest design was used. A convenience sample of Black adolescent girls between the age of 12-18 (n = 41). A 60-min 12-week church-based program that included interactive educational sessions followed by a high energy dance aerobics class was used. Data were collected on biophysical measures. Surveys were used to assess the following variables: attitudes, enjoyment, self-efficacy, intention, social and family support, and PA levels. Paired t-tests and repeated measures ANOVA revealed no significant changes in key variables. Positive changes were noted in the odds ratios for attitudes, self-efficacy, and intention. Body mass index, metabolic equivalent tasks, and fitness showed positive trends from pre to post intervention. Family support was significantly correlated with physical activity level (p adolescent girls are feasible. Participants evaluated the intervention very favorably. Family support may be a key factor in increasing physical activity levels in Black adolescent girls. © 2012 Wiley Periodicals, Inc.

    The Principles of Technology (PT) curriculum, now in approximately 1,200 schools, has produced a profound change in the delivery of applied physics. If high school PT programs and traditional physics courses deliver comparable student outcomes, as some research suggests, the PT curriculum may find wider acceptance in vocational programs and postsecondary schools may have rationale for accepting PT as physics. This study measured PT student performance on an advanced physics test, after they have had one year (7 units) of PT. The 1988R version of the National Association of Physics Teachers and National Science Teachers Association physics test, with more than 7500 copies sold, was selected as the research instrument. This test covers advanced aspects of traditional high school physics. A secondary enquiry included an attempt to link PT teacher preparation and credentialing and/or PT site demographics to variation in PT student scores on the 1988R test. The 10 PT sites in this study were self-selected from the 29 PT field study schools, the most mature PT sites. The researcher determined, that the 1988R physics test lacked content validity for the PT students tested. The PT students tested had a composite mean score of 17.67 questions correct out of 80, (below the second percentile), not statistically different than a chance score. No differences were found between site mean scores. Interpretation of the results regarding the effect of teachers, or demographics was not justified. The value of PT to the vocational-technical programs that it was designed for was not measured, nor was the awarding of general science credit for PT completion. One year of the PT curriculum, at the sampled schools, has not prepared students in the advanced scientific aspects of traditional physics found on the 1988R examination. The primary implication is that educators should not expect year one PT to prepare students for classes or curricula that include traditional physics as a

    To examine factors associated with regular physical activity in Croatian adolescents. A cross-sectional survey among high school students was carried out in the 2013/14 school year. A survey was conducted among 33 high schools in Zagreb City, Croatia. Participants were students aged 17-18 years. The dependent variables were regular moderate to vigorous physical activity (MVPA) and overall physical activity measured by the short version of International Physical Activity Questionnaire and defined as 60 min or more of daily physical activity. The independent variables included family, neighborhood, and high school social capital. Other study covariates included: socio-economic status, self-rated health, psychological distress and nutritional status. The associations between physical activity and social capital variables were assessed separately for boys and girls through multiple logistic regression and inverse probability weighting in order to correct for missing data bias. A total of 1689 boys and 1739 girls responded to the survey. A higher percentage of boys reported performing regular vigorous and moderate physical activity (59.4%) and overall physical activity (83.4%), comparing with the girls (35.4% and 70%, respectively). For boys, high family social capital and high informal social control were associated with increased odds of regular MVPA (1.49, 95%CI: 1.18 - 1.90 and 1.26, 95%CI: 1.02 - 1.56, respectively), compared to those with low social capital. For girls, high informal social control was associated with regular overall physical activity (OR 1.38, 95% CI: 1.09 - 1.76). High social capital is associated with regular MVPA in boys and regular overall activity in girls. Intervention and policies that leverage community social capital might serve as an avenue for promotion of physical activity in youth. Copyright © 2016 The Royal Society for Public Health.

    Full Text Available The University of KwaZulu-Natal is in the process of formulating a language policy to introduce teaching and learning in isiZulu as well as in English to improve throughput and increase the number of graduates. The aim of this study was to determine if this policy is feasible within the discipline of physics. Critical engagement with students and a literature search allowed the determination of the potential gains and pitfalls of such a language introduction. The study also provides some useful insight into student contexts, schooling history and their perceptions of being taught in their vernacular. The inconsistent use of isiZulu words to translate basic physics words will require the development of a common vocabulary for teaching physics in isiZulu.

    Full Text Available Treating asthmatic students in the university environment has been a ministerial concern. Multiple actions aimed at preparing teachers to conduct the teaching of therapeutic physical culture are developed from the methodological work. In it offered theoretical, methodological and experiential tools for therapeutic exercises generate a developer student learning. Nevertheless, there are still limitations that reveal the need to give continuity to these intentions. One is the traditional approach of the exercises for therapeutic purposes. If we consider that today's society demands the formation of a subject becomes heir and transmitter of a culture of physical activity that achieves deal with their conditions, increasing growing life expectancy, then more than rehabilitation the physical must achieve a comprehensive educational impact.

    We tested whether the Good School Toolkit reduces physical violence from peers and school staff toward students with and without disabilities in Ugandan primary schools. We conducted a cluster randomized controlled trial, with data collected via cross-sectional surveys in 2012 and 2014. Forty-two primary schools in Luwero District, Uganda, were randomly assigned to receive the Good School Toolkit for 18 months, or to a waitlisted control group. The primary outcome was past week physical violence from school staff, measured by primary 5, 6, and 7 students' (aged 11-14 years) self-reports using the International Society for the Prevention of Child Abuse and Neglect Child Abuse Screening Tool-Child Institutional. Disability was assessed through the six Short Set Washington Group questions on functioning. Analyses were by intention to treat. At endline, 53% of control group students with no functional difficulties reported violence from peers or school staff, versus 84% of students with a disability. Prevalence of past week physical violence from school staff was lower in intervention schools than in the control schools after the intervention, in students with no functional difficulties (adjusted odds ratio [aOR] = .41, 95% confidence interval [CI .26-.65]), students with some functional difficulties (aOR = .36, 95% CI .21-.63), and students with disabilities (aOR = .29, 95% CI .14-.59). The intervention also reduced violence from peers in young adolescents, with no evidence of a difference in effect by disability status. The Good School Toolkit is an effective intervention to reduce violence perpetrated by peers and school staff against young adolescents with disabilities in Ugandan primary schools.

    Orthorexia nervosa is described as an exaggerated fixation on healthy food. It is unclear whether students in health-oriented academic programs, highly focused on physical exercise, are more prone to develop orthorexia nervosa than students in other educational areas. The aim was to compare health status, physical activity, and frequency of orthorexia nervosa between university students enrolled in an exercise science program (n = 118) or a business program (n = 89). The students completed the Short Form-36 Health Survey (SF-36), the International Physical Activity Questionnaire (IPAQ), and ORTO-15, which defines orthorexia nervosa as a sensitive and obsessive behavior towards healthy nutrition. The SF-36 showed that exercise science students scored worse than business students regarding bodily pain (72.8 vs. 82.5; p = 0.001), but better regarding general health (83.1 vs. 77.1; p = 0.006). Of 188 students, 144 (76.6%) had an ORTO-15 score indicating orthorexia nervosa, with a higher proportion in exercise science students than in business students (84.5% vs. 65.4%; p = 0.002). Orthorexia nervosa in combination with a high level of physical activity was most often seen in men in exercise science studies and less often in women in business studies (45.1% vs. 8.3%; p orthorexia nervosa in exercise science students may cause problems in the future, since they are expected to coach others in healthy living. Our findings may be valuable in the development of health-oriented academic programs and within student healthcare services. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2012-12-01

    The purpose of this study was to assess the short-term effect of a physical fitness program on physical self-concept and physical fitness elements among primary school students. Spanish boys and girls (N = 75; M age = 11.1 yr., SD = 0.4) were divided into an experimental group and a control group. During physical education classes, the experimental group performed an 8-week program including two circuits of 8 exercises done for 15 to 35 sec. each with 45 to 25 sec. of rest between them. Physical self-concept (Physical Self-Description Questionnaire) and physical fitness (EUROFIT battery tests) were measured at the beginning and at the end of the physical fitness program. The results showed that the improvements in physical fitness were not accompanied by major changes in physical self-concept, even though the physical fitness program seemed to maintain the Experimental group's previous physical appearance, strength, and self-esteem perceptions, all of which statistically significantly decreased in the control group after the intervention.

  10. Engaging undergraduate students in hadron physics research and instrumentation

    Nuclear physics research is fundamental to our understanding of the visible universe and at the same time intertwined with our daily life. Nuclear physics studies the origin and structure of the atomic nuclei in terms of their basic constituents, the quarks and gluons. Atoms and molecules would not exist without underlying quark-gluon interactions, which build nearly all the mass of the visible universe from an assembly of massless gluons and nearly-massless quarks. The study of hadron structure with electromagnetic probes through exclusive and semi-inclusive scattering experiments carried out at the 12 GeV Jefferson Laboratory plays an important role in this effort. In particular, planned precision measurements of pion and kaon form factors and longitudinal-transverse separated deep exclusive pion and kaon electroproduction cross sections to the highest momentum transfers achievable play an important role in understanding hadron structure and masses and provide essential constraints for 3D hadron imaging. While a growing fraction of nuclear physics research is carried out at large international laboratories, individual university research groups play critical roles in the success of that research. These include data analysis projects and the development of state-of-the-art instrumentation demanded by increasingly sophisticated experiments. These efforts are empowered by the creativity of university faculty, staff, postdocs, and provide students with unique hands-on experience. As an example, an aerogel Cherenkov detector enabling strangeness physics research in Hall C at Jefferson Lab was constructed at the Catholic University of America with the help of 16 undergraduate and high school students. The ''Conference Experience for Undergraduates'' (CEU) provides a venue for these students who have conducted research in nuclear physics. This presentation will present the experiences of one of the participants in the first years of the CEU, her current research program

  11. Attempt to explain black hole spin in X-ray binaries by new physics

    International Nuclear Information System (INIS)

    Bambi, Cosimo

    2015-01-01

    It is widely believed that the spin of black holes in X-ray binaries is mainly natal. A significant spin-up from accretion is not possible. If the secondary has a low mass, the black hole spin cannot change too much even if the black hole swallows the whole stellar companion. If the secondary has a high mass, its lifetime is too short to transfer the necessary amount of matter and spin the black hole up. However, while black holes formed from the collapse of a massive star with solarmetallicity are expected to have low birth spin, current spin measurements show that some black holes in X-ray binaries are rotating very rapidly. Here we show that, if these objects are not the Kerr black holes of general relativity, the accretion of a small amount of matter (∝2 M s un) can make them look like very fast-rotating Kerr black holes. Such a possibility is not in contradiction with any observation and it can explain current spin measurements in a very simple way. (orig.)

    Science, Technology, Engineering, and Mathematics (STEM) fields are critical for meeting ever-increasing demands in the U.S. for STEM and related skills, and for ensuring the global competitiveness of the United States in technological advancement and scientific innovation. Nonetheless, few U.S. students consider a STEM degree after high school and fewer STEM students end up graduating with a STEM degree. In 2012, the United States ranked 35th in math and 27th in science out of 64 participating countries in the Program for International Student Assessment (PISA), sponsored by the Organization for Economic Cooperation and Development (OECD). Considering the significant role physics and engineering play in technological advancement, this work investigates the attitudes of students and recent enrollment trends in these important subject areas.

    Full Text Available The study investigated the relationship between body mass index and self-concept among adolescent black female university students. The study used a mixed research design (quantitative and qualitative methods. Media images of handsome faces and beautiful bodies are used to sell almost everything, from clothes and cosmetic to luncheon, meats, and so on. These images reinforce the western cultural stereotype that women should be thin and shapely to be attractive. Thus, as some girls go through puberty they may become dissatisfied with their weight, and to a lesser extent, with their shape, thus, developing low self-concept or imae of themselves. It is in this context that the study was conceptualised.

    Adele Anna Teleman

    2015-06-01

    Full Text Available INTRODUCTION: Physical activity, diet plans, the mantainment of a certain Body Mass Index (BMI and the use of various types of supplementation are common elements in the search for disease prevention, health promotion and well-being. MATERIALS AND METHODS: We analyzed the data regarding Italian university students' BMI, dieting behaviour, personal body perception, exercise habits, and use of dietary supplements and of doping substances. RESULTS: 13.7% resulted being underweight, 75.1% was in the normal range, 9.8% was overweight, and 1.4% was obese. 11.0% were on a diet. 25.8% of the students reported never doing any type of physical activity. 0.9% admitted consuming doping substances. The percentage of overweight/obese students increases from 8.8% of the 18-21 year olds to 18.1% of the 25-30 year olds. Similarly, the prevalence of overweight/obesity was 18.5% among male population and 7.5% among the female one. DISCUSSION: The data deriving from this questionnaire showed that while the majority of university students has a BMI in the normal range, 11.2% of the study population is overweight/obese. Males present a higher risk of being overweight or obese. An important part of the population showed to be sedentary even though data coming from our study are aligned to further evidence. CONCLUSION: The most important concern arising from the questionnaire is represented by physical inactivity. Indeed, it is necessary to encourage and plan initiatives aimed at promoting physical activity in university students.

  7. A study of student perceptions of physics teacher behavior

    Science.gov (United States)

    Brekelmans, Mieke; Wubbels, Theo; Créton, Hans

    This study investigates student perceptions of the behavior of physics teachers in relation to some other variables in the classroom situation. The research was carried out as a Dutch option of the Second International Science Study. Data were gathered in 65 classrooms of physics teachers with pupils 15 years old. Some of the teachers (21) used the new PLON curriculum and the others a traditional one. Student perceptions of teacher behavior were measured with a questionnaire based on the interpersonal theory of Leary (1957). The aspect of behavior measured is called interactional teacher behavior. We found remarkably high correlations between student perceptions of teacher behavior and affective outcomes such as appreciation of the lessons and motivation for the subject matter. Also, the correlations with cognitive outcomes measured with a standardized international test were significant. It appears that some differences exist between teacher behaviors that are favorable for high cognitive outcomes and behaviors favorable for high affective outcomes in physics lessons. Hardly any differences were found in teacher behavior between teachers using the traditional and the new physics curriculum.

    All high school students that wish to continue onto college are seeking opportunities to be competitive in the college market. They participate in extra-curricular activities which are seen to foster creativity and the skills necessary to do well in the college environment. In the case of students with an interest in physics, participating in a small scale research project while in high school gives them the hands on experience and ultimately prepares them more for the college experience. SUNY Plattsburgh’s Physics department started a five-week summer program for high school students in 2012. This program has proved not only beneficial for students while in the program, but also as they continue on in their development as scientists/engineers. Independent research, such as that offered by SUNY Plattsburgh’s five-week summer program, offers students a feel and taste of the culture of doing research, and life as a scientist. It is a short-term, risk free way to investigate whether a career in research or a particular scientific field is a good fit.

    Full Text Available Inclusion is a social process in school aims to change attitudes and to build a position to cover everyone without distinction. Thus, the objective was to analyze the representations of deaf students on their inclusion in physical education classes. It is qualitative, descriptive and analytical, attended eight deaf students from 2 public schools in a city in the countryside of Bahia. For data production, it was used a semi -structured interview, through the aid of an interpreter of Brazilian Sign Language (Libras, at the same time, it was translated by the interpreter and transcribed by the researchers. Data analysis used the technique of categorical content analysis. The inclusion of deaf people in physical education classes still failed to materialize and in fact, even having found some teachers with pedagogical actions that proved to be inclusive, yet they still leave many gaps, regarding satisfactory learning of students because they simply just integrate deaf students in the classroom. It is necessary that the school and the teacher ensure that the curriculum is accessible to them, so that they can contribute to the construction of citizenship, motor development, cognitive and social-emotional student.

    This study investigates the gaze patterns of undergraduate college students attending a lecture-based physical science class to better understand the relationships between gaze and focus patterns and student attention during class. The investigators used a new eye-tracking product; Tobii Glasses. The glasses eliminate the need for subjects to focus on a computer screen or carry around a backpack-sized recording device, thus giving an investigator the ability to study a broader range of research questions. This investigation includes what students focus on in the classroom (i.e. demonstrations, instructor, notes, board work, and presentations) during a normal lecture, what diverts attention away from being on task as well as what keeps a subject on task. We report on the findings from 8 subjects during physical science lectures designed for future elementary school teachers. We found that students tended not to focus on the instructor for most parts of the lecture but rather the information, particularly new information presented on PowerPoint slides. Finally, we found that location in the classroom also impacted students' attention spans due to more distractors.

  13. EVIDENCE FOR LOW BLACK HOLE SPIN AND PHYSICALLY MOTIVATED ACCRETION MODELS FROM MILLIMETER-VLBI OBSERVATIONS OF SAGITTARIUS A*

    International Nuclear Information System (INIS)

    Broderick, Avery E.; Fish, Vincent L.; Doeleman, Sheperd S.; Loeb, Abraham

    2011-01-01

    Millimeter very long baseline interferometry (mm-VLBI) provides the novel capacity to probe the emission region of a handful of supermassive black holes on sub-horizon scales. For Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, this provides access to the region in the immediate vicinity of the horizon. Broderick et al. have already shown that by leveraging spectral and polarization information as well as accretion theory, it is possible to extract accretion-model parameters (including black hole spin) from mm-VLBI experiments containing only a handful of telescopes. Here we repeat this analysis with the most recent mm-VLBI data, considering a class of aligned, radiatively inefficient accretion flow (RIAF) models. We find that the combined data set rules out symmetric models for Sgr A*'s flux distribution at the 3.9σ level, strongly favoring length-to-width ratios of roughly 2.4:1. More importantly, we find that physically motivated accretion flow models provide a significantly better fit to the mm-VLBI observations than phenomenological models, at the 2.9σ level. This implies that not only is mm-VLBI presently capable of distinguishing between potential physical models for Sgr A*'s emission, but further that it is sensitive to the strong gravitational lensing associated with the propagation of photons near the black hole. Based upon this analysis we find that the most probable magnitude, viewing angle, and position angle for the black hole spin are a = 0.0 +0.64+0.86 , θ=68 o+5 o +9 o -20 o -28 o , and ξ=-52 o+17 o +33 o -15 o -24 o east of north, where the errors quoted are the 1σ and 2σ uncertainties.

  17. 2T Physics, Weyl Symmetry and the Geodesic Completion of Black Hole Backgrounds

    Science.gov (United States)

    Araya Quezada, Ignacio Jesus

    In this thesis, we discuss two different contexts where the idea of gauge symmetry and duality is used to solve the dynamics of physical systems. The first of such contexts is 2T-physics in the worldline in d+2 dimensions, where the principle of Sp(2,R) gauge symmetry in phase space is used to relate different 1T systems in (d -- 1) + 1 dimensions, such as a free relativistic particle, and a relativistic particle in an arbitrary V(x2) potential. Because each 1T shadow system corresponds to a particular gauge of the underlying symmetry, there is a web of dualities relating them. The dualities between said systems amount to canonical transformations including time and energy, which allows the different systems to be described by different Hamiltonians, and consequently, to correspond to different dynamics in the (d -- 1)+1 phase space. The second context, corresponds to a Weyl invariant scalar-tensor theory of gravity, obtained as a direct prediction of 2T gravity, where the Weyl symmetry is used to obtain geodesically complete dynamics both in the context of cosmology and black hole (BH) backgrounds. The geodesic incompleteness of usual Einstein gravity, in the presence of singularities in spacetime, is related to the definition of the Einstein gauge, which fixes the sign and magnitude of the gravitational constant GN, and therefore misses the existence of antigravity patches, which are expected to arise generically just beyond gravitational singularities. The definition of the Einstein gauge can be generalized by incorporating a sign flip of the gravitational constant GN at the transitions between gravity and antigravity. This sign is a key aspect that allows us to define geodesically complete dynamics in cosmology and in BH backgrounds, particularly, in the case of the 4D Schwarzschild BH and the 2D stringy BH. The complete nature of particle geodesics in these BH backgrounds is exhibited explicitly at the classical level, and the extension of these results to the

    Large amounts of aerosol, including black carbon (BC), are emitted from biomass burning. It is therefore important to understand the chemical composition, rate of emissions, and mixing state of aerosols generated by this combustion process to estimate the impacts of aerosols on climate. Thus far, these physical and chemical quantities have been compiled by combining the data from laboratory and field experiments, but the data from the Arctic region are still very limited. These parameters were measured by an SP2 instrument based on the laser-induced incandescence technique on board the NASA DC-8 during the ARCTAS campaign. Aircraft sampling was made in plumes emitted by wildfires in Canada and the USA, and in those transported over long distances from Russia. First, we extract biomass burning plumes using CH3CN and SO2 data. Then, we derived the slopes of the CO-CO2-CH3CN-aerosol correlations for each burning plume. Based on this, we derive the average CO/CO2, CH3CN/CO2, BC/CO2, and BC/CO ratios together with their variability in the plumes strongly influenced by forest fires over Siberia, California, and Canada. A similar analysis is made for light-scattering particles. Using these relationships, the transport efficiencies of BC particles from the boundary layer to the free troposphere are also estimated. It is found that the BC particles were thickly coated upon emission. From comparison with AMS measurements, the coating materials are found to be mainly composed of organic compounds. This indicates the importance of the enhanced light absorption by BC particles emitted by biomass burning.

    1992-11-24

    THE REAL STUFF is an Expanded Media Physics Course aimed at students still in the formative early years of secondary school. Its consists of a working script for an interactive multimedia study unit in basic concepts of physics. The unit begins with a prologue on the Big Bang that sets the stage, and concludes with a lesson on Newton's first law of motion. The format is interactive, placing the individual student in control of a layered hypermedia'' structure that enables him or her to find a level of detail and difficulty that is comfortable and meaningful. The intent is to make physics relevant, intellectually accessible and fun. On-screen presenters and demonstrators will be females and males of various ages, ethnicities and backgrounds, and will include celebrities and physicists of note. A lean, layered design encourages repeated, cumulative study and makes the material useful for self-directed Teaming even by college students. THE REAL STUFF introduces a new science teaching paradigm, a way to teach science that will engage even students who have declined'' to be interested in science in the past. Increased participation in science by women, African-Americans and Spanish-speaking students is a particular goal.

    Full Text Available Many studies which were published in other countries identified certain benefits and barriers to physical activity among young people. But there is no data about the subject pertaining to Turkish adolescents. This study tries to rectify this with a study of Turkish university students. Undergraduate university students (n = 303 were recruited to the study. Current exercise habits and perceived barriers to physical activity were assessed in the sample. Using a Likert Type scale, participants responded an instrument with 12 items representing barriers to physical activity. Mean scores were computed. External barriers were more important than internal barriers. "Lack of time due to busy lesson schedule", "My parents give academic success priority over exercise." and "lack of time due to responsibilities related to the family and social environment" were most cited items for physical activity barriers. There is a need for future research, which will be carried out with larger sample groups to develop national standardized instrument. It will be helpful for accurately identify perceived barriers and then recommend changes to enhance physical activity among young people.

    The study investigated the relationship between body mass index and self-concept among adolescent black female university students. The study used a mixed research design (quantitative and qualitative methods). Media images of handsome faces and beautiful bodies are used to sell almost everything, from clothes and cosmetic to luncheon, meats, and so on. These images reinforce the western cultural stereotype that women should be thin and shapely to be attractive. Thus, as some girls go through puberty they may become dissatisfied with their weight, and to a lesser extent, with their shape, thus, developing low self-concept or imae of themselves. It is in this context that the study was conceptualised. First year female students from three different Schools and Faculties at the University of Limpopo, Turfloop Campus, South Africa, participated in the study. Using the availability and convenient sampling method, 75 students were selected for this study. For the quantitative aspect of the study, the Rosenberg Self-esteem Measure was used to measure self-esteem. For the qualitative part, a topic guide was used for the focus group discussions. Analysis of Variance (ANOVA) and the Pearson's Product Moment Correlation were used to analyse the quantitative data, while the phenomenological principle of open coding used for the thematic analysis. Results showed that there is a relationship between body mass and self-concept and that overweight participants tend to have a low self-esteem. Low self-esteem was perceived to be aggravated by a number of factors, like the attitude of the media and the society. Participants who are overweight also indicated that they are limited in certain activities of daily living (e.g., sports) as a result of their body mass. They expressed mixed feelings and frustration when it comes to such activities. The above results did not differ from those reported from western cultures. Support groups, life-skills programmes and psychotherapy should be

    Full Text Available Objective:  to identify the stress levels and sleeping habits of students from the Physical Education college during the diurnal and nocturnal periods. Method: this is an exploratory and descriptive study with 103 subjects. Data were collected through the Lipp Stress Symptom Inventory and the Horne & Östberg Morningness-Eveningness Identification Questionnaire, and sociodemographic data. Results: The stress indexes showed 53.40% of students without stress and 46.6% with stress. When comparing gender and stress using the chi-square test, one obtained (p=0.0411, indicating that women are more stressed than men. There were 61.1% of students classified with indifferent chronotype. Among the students, 80.4% from the diurnal period were not suitable for the chronotype, as well as 74.5% of the students from the nocturnal period were not either. Conclusion: the majority of the students did not present the chronotype adequate for the study schedule and they presented stress, being more frequent in the female group.

    In this study, the subjective and objective voice measures of seven female physical education student teachers during a semester of student teaching were investigated. The participants completed the voice measures at three data collection time points: baseline, middle, and end of the semester. The voice measures included acoustic and aerodynamic data, perceptual rating scales of vocal quality and vocal fatigue, an end-of-semester questionnaire, and the Voice Handicap Index. Results demonstrated that the subjective and objective voice measures changed at the middle and the end of the semester as compared with those at baseline. The change in the voice measures may suggest that the vocal mechanism was adapting to the increased vocal demands of teaching physical education. Copyright © 2011 The Voice Foundation.

    We present a novel integrated methodology for the development and production of accessible physics and science books from the elementary up to tertiary educational levels. This language independent approach adopts the Design-for-All principles, the available international standards for alternative formats and the Universal Design for Learning (UDL) Guidelines. Moreover it supports both static (embossed and refreshable tactile) and dynamic (based on synthetic speech and other sounds) accessibility. It can produce Tactile Books (Embossed Braille and Tactile Graphics), Digital Talking Books (or Digital Audio Books), Large Print Books as well as Acoustic-Tactile Books for the blind and visually impaired students as well as but for the print-disabled. This methodology has been successfully applied in the case of blind students of the Physics, Mathematics and Informatics Departments in the University of Athens.

    At the beginning of academic year 2007-08, staff in the Department of Physics and Astronomy at the University of Glasgow started to implement a number of substantial changes to the administration of the level 1 physics undergraduate class. The main aims were to improve the academic performance and progression statistics. With this in mind, a comprehensive system of learning support was introduced, the main remit being the provision of an improved personal contact and academic monitoring and support strategy for all students at level 1. The effects of low engagement with compulsory continuous assessment components had already been observed to have a significant effect on students sitting in the middle of the grade curve. Analysis of data from the 2007-08 class showed that even some nominally high-achieving students achieved lowered grades due to the effects of low engagement. Nonetheless, academic and other support measures put in place during 2007-08 played a part in raising the passrate for the level 1 physics class by approximately 8% as well as raising the progression rate by approximately 10%.

  15. A qualitative study on student attitudes towards a controversial species, the black-tailed prairie dog (Cynomys ludovicianus)

    Fox-Parrish, Lynne

    This case study determined the attitudes held by high school students toward a controversial, yet keystone, species of the Great Plains, the black-tailed prairie dog. Black-tailed prairie dogs have declined dramatically over the past century as a result of large scale poisoning programs, plague, shooting, and habitat loss. The eradication programs put forth were primarily the result of strongly held misconceptions regarding black-tailed prairie dogs. The misconceptions are ingrained in many agricultural and/or rural communities throughout the prairie dogs' range. The decline of this species has resulted in the decline of many other species and the near extinction of the black-footed ferret. Biodiversity continues to decline and the health of the prairie dog ecosystem (i.e. prairie habitats) is in jeopardy. Although studies have shown that landowners and the adult population that live within the range of black-tailed prairie dogs harbor negative attitudes, nothing is known about the attitudes of adolescents. With an eco-feminist theoretical perspective, a case study methodology was used. Thirty 9th grade students comprised the case. The students lived in a mid-sized urban northern Colorado city whose county ranks 5th in the nation and 1st state wide for the value of their agricultural products. Black-tailed prairie dogs could be found throughout the city and adjacent areas. Students were engaged in a year-long "lesson" on black-tailed prairie dogs and conducted a field research experiment on an active prairie dog town. Interviews were conducted in May 2004. Follow-up interviews were conducted in May 2005. Other data collected were: observations, photographs, journals, and classroom documents. Themes generated were devised by a constant comparative method of data analysis. Three major themes emerged: apathy, egocentrism, and naive conceptions. Two smaller themes also emerged: caring and hopelessness. Adolescents are our future policy and decision makers; therefore

    Researchers have examined the physical activity (PA) habits of certified athletic trainers; however, none have looked specifically at athletic training students. To assess PA participation and constraints to participation among athletic training students. Cross-sectional study. Entry-level athletic training education programs (undergraduate and graduate) across the United States. Participants were 1125 entry-level athletic training students. Self-reported PA participation, including a calculated PA index based on a typical week. Leisure constraints and demographic data were also collected. Only 22.8% (252/1105) of athletic training students were meeting the American College of Sports Medicine recommendations for PA through moderate-intensity cardiorespiratory exercise. Although 52.3% (580/1105) were meeting the recommendations through vigorous-intensity cardiorespiratory exercise, 60.5% (681/1125) were meeting the recommendations based on the combined total of moderate or vigorous cardiorespiratory exercise. In addition, 57.2% (643/1125) of respondents met the recommendations for resistance exercise. Exercise habits of athletic training students appear to be better than the national average and similar to those of practicing athletic trainers. Students reported structural constraints such as lack of time due to work or studies as the most significant barrier to exercise participation. Athletic training students experienced similar constraints to PA participation as practicing athletic trainers, and these constraints appeared to influence their exercise participation during their entry-level education. Athletic training students may benefit from a greater emphasis on work-life balance during their entry-level education to promote better health and fitness habits.

    This study examined traditional instruction and problem-based learning (PBL) approaches to teaching and the extent to which they foster the development of desirable cognitive processes, including metacognition, critical thinking, physical intuition, and problem solving among undergraduate physics students. The study also examined students' approaches to learning and their perceived role as physics students. The research took place in the context of advanced courses of electromagnetism at a Canadian research university. The cognitive science, expertise, physics and science education, instructional psychology, and discourse processes literature provided the framework and background to conceptualize and structure this study. A within-stage mixed-model design was used and a number of instruments, including a survey, observation grids, and problem sets were developed specifically for this study. A special one-week long problem-based learning (PBL) intervention was also designed. Interviews with the instructors participating in the study provided complementary data. Findings include evidence that students in general engage in metacognitive processes in the organization of their personal study time. However, this potential, including the development of other cognitive processes, might not be stimulated as much as it could in the traditional lecture instructional context. The PBL approach was deemed as more empowering for the students. An unexpected finding came from the realisation that a simple exposure to a structured exercise of problem-solving (pre-test) was sufficient to produce superior planning and solving strategies on a second exposure (post-test) even for the students who had not been exposed to any special treatment. Maturation was ruled out as a potential threat to the validity of this finding. Another promising finding appears to be that the problem-based learning (PBL) intervention tends to foster the development of cognitive competencies, particularly

    Multiple approaches that can contribute to reducing obesity have been proposed. These policies may share overlapping pathways, and may have unanticipated consequences, creating considerable complexity. Aiming to illuminate the use of agent-based models to explore the consequences of key policies, this paper simulates the effects of increasing neighbourhood availability of good food stores, physical activity infrastructure and higher school quality on the reduction of black/white disparities in body mass index (BMI) in the USA. We used an agent-based model, with parameters derived from the empirical literature, which included individual and neighbourhood characteristics over the life course as determinants of behaviours thought to impact BMI. We systematically varied the strength of the 3 policy interventions, examining the impact of 125 different policy scenarios on black/white BMI disparities. In the absence of any of these policies, black/white BMI disparities generally increased over time. However, we found that some combinations of these policies resulted in reductions in BMI, yielding decreases in the black/white BMI disparity as large as a 90%. Within the structure of relationships captured in this simulation model, there is support for the further use of agent-based simulation models to explore upstream policies as plausible candidates for the reduction of black/white disparities in BMI. These results highlight the potential insights into important public health problems, such as obesity, that can come from uniting the systems science approach with policy analysis.

    To examine academically dishonest behaviours based on physical therapy (PT) students' current practices and educators' prior behaviours as PT students. A Web-based questionnaire was sent to 174 students and 250 educators from the PT programme at the University of Toronto. The questionnaire gathered data on demographics as well as on the prevalence of, seriousness of, and contributing factors to academic dishonesty (AD). In all, 52.4% of educators and 44.3% of students responded to the questionnaire over a 6-week data-collection period. Scenarios rated the most serious were the least frequently performed by educators and students. The impact of generation on attitudes and prevalence of AD was not significant. The factors most commonly reported as contributing to AD were school-related pressure, disagreement with evaluation methods, and the perception that "everyone else does it." This study parallels the findings of similar research conducted in other health care programmes: AD does occur within the PT curriculum. AD was more prevalent in situations associated with helping peers than in those associated with personal gain. The consistency in behaviours reported across generations suggests that some forms of cheating are accepted as the social norm and may be a function of the environment.

    Full Text Available The origin of black magnetic spherules sampled in air,
    and in ancient and recent marine sediments has been investigated.
    Experiments were performed reproducing in laboratory the same processes undergone by the cosmic dust during its flight through the atmosphere.
    Spherules similar in size, shape, chemical and mineralogieal characteristics to the natural ones have been obtained. It has been tested that hollow spherules can be also produced in the high atmosphere.
    The bubble formed inside some black magnetic spherules by the decrease of solubility of oxygen at the melting point can be sometimes ejected from the rear side of the spherule producing secondary particles less than 10 pim is size.
    The volcanic origin of black magnetic spherules has been excluded.
    In fact ferromagnetic volcanic particulate matter present mineralogic,
    chemical and structural characteristics different from that of black magnetic spherules.
    Also the use of some parameters is suggested to discriminate industrial
    ferromagnetic spherules from black magnetic spherules of extraterrestrial origin.
    Samples from sediments old enough to exclude industrial contamination

  12. An Introduction to Tensors for Students of Physics and Engineering

    Kolecki, Joseph C.

    2002-01-01

    Tensor analysis is the type of subject that can make even the best of students shudder. My own post-graduate instructor in the subject took away much of the fear by speaking of an implicit rhythm in the peculiar notation traditionally used, and helped us to see how this rhythm plays its way throughout the various formalisms. Prior to taking that class, I had spent many years "playing" on my own with tensors. I found the going to be tremendously difficult but was able, over time, to back out some physical and geometrical considerations that helped to make the subject a little more transparent. Today, it is sometimes hard not to think in terms of tensors and their associated concepts. This article, prompted and greatly enhanced by Marlos Jacob, whom I've met only by e-mail, is an attempt to record those early notions concerning tensors. It is intended to serve as a bridge from the point where most undergraduate students "leave off" in their studies of mathematics to the place where most texts on tensor analysis begin. A basic knowledge of vectors, matrices, and physics is assumed. A semi-intuitive approach to those notions underlying tensor analysis is given via scalars, vectors, dyads, triads, and higher vector products. The reader must be prepared to do some mathematics and to think. For those students who wish to go beyond this humble start, I can only recommend my professor's wisdom: find the rhythm in the mathematics and you will fare pretty well.

    The ratio of shear viscosity to volume density of entropy can be used to characterize how close a given fluid is to being perfect. Using string theory methods, we show that this ratio is equal to a universal value of variant Planck's over 2pi/4pik(B) for a large class of strongly interacting quantum field theories whose dual description involves black holes in anti-de Sitter space. We provide evidence that this value may serve as a lower bound for a wide class of systems, thus suggesting that black hole horizons are dual to the most ideal fluids.

    Black young adults have lower rates of alcohol use than other racial groups. Genetic factors may protect against drinking. Specifically, the ADH1B*3 allele is present almost exclusively in Black populations and has been protective against alcohol use and alcohol use disorder. The protective effects of the ADH1B*3 allele, however, may differ as a function of alcohol-promoting cognitions. The current study examined whether ADH1B*3 moderated relations of drinking motives with alcohol consumption among Black college drinkers. Participants were 241 undergraduate students of self-identified Black race (mean age = 20 years; 66% female) who reported consuming alcohol at least once in the past 30 days. ADH1B*3 was not significantly associated with drinking motives or drinking behaviors. However, significant, albeit small, interaction effects of ADH1B*3 with drinking motives on drinking behavior were found; the presence of an ADH1B*3 allele protected against greater drinking quantity among students with high social motives (incidence rate ratio [IRR] = 0.95, 95% CI [0.92, 0.99]) and against frequent drinking among students with low coping motives (IRR = 1.06, 95% CI [1.01, 1.11]). These findings represent a novel demonstration of genetic modulation of alcohol-related cognitions within Black college drinkers, although replication is needed. Results represent an initial step toward better characterizing individual differences in associations of drinking motives with drinking behavior, with potential implications for interventions aimed at motivational processes in alcohol use.

    Full Text Available The paper discusses the physical education problems in the context of environmental degradation, uncertainty of socio-economic situation and ideological setting, informational boom, wide spread of the alcohol and drug abuse, etc. As a solution to the problem, the author recommends to propagate the sport lifestyle to university students by creating the proper sports environment; the factors determining the given life style being emphasized, the definition of the university sports environment, its structure and functional system demonstrated. The author describes the theoretical and applied aspects of the environmental approach to physical education based on the constructive interaction and cooperation of teachers and students. The paper considers the sports activity – a semantic core of the approach in question – in terms of the specific sport facilities, behavior regulating rules, and students’ free choice of sport, place and schedules. The conceptual basis of the given approach incorporates the ideas of developmental education and complies with the Federal State Educational Standards. In conclusion, the author demonstrates the changing dynamics of students’ motivation for the mass sports activity resulted from implementation of the environmental approach to physical education at Tumen State University.

    Full Text Available Health profession students may need help establishing and maintaining positive health behaviors when they are in college. This study explored the effectiveness of text messaging as an innovative method for promoting an increase in daily physical activity. A convenience sample (N = 134 was recruited from students at a college of Health and Human Services in Michigan. The participants were randomized into an intervention or control group (n = 67 each. The intervention group received daily affective text messages encouraging more physical activity by taking more steps. The control group received only messages reminding them to report their number of steps. All of the participants received a pedometer, completed a demographics and daily habits questionnaire, and completed the Perceived Stress Scale (PSS. There was no significant difference between the intervention and control groups in their number of daily steps. However, the most inactive participants had a significant increase in steps during the study period. Health profession students’ lifestyle behaviors have consequences, as they become caregivers in our dynamic, demanding health-care system. For those with the greatest need for physical activity, encouraging such activity via text messaging may improve their ability to care for themselves and their clients.

  20. Vignettes of scholars: A case study of black male students at a STEM early college high school

    Science.gov (United States)

    Adams, Tempestt Richardson

    Ensuring students graduate high school ready to enter college or the workforce has become a prime focus within secondary education. High school graduates are often ill-prepared for college-level work and often have to register for remedial courses before they can take standard college level courses (Southern Regional Education Board, 2010). Serving as both a solution to this concern and an alternative to traditional high schools, early college high schools were created to focus on increasing the number of students graduating from high school and enrolling in college. Early college high schools seek to serve students who have traditionally underperformed in school and those who are underrepresented in higher education including students of color, first-generation college students, students from low socioeconomic backgrounds, and English language learners (Barnett, Bucceri, Hindo, Kim, 2013; "Overview & FAQS," 2013). In efforts to learn more about how early colleges are meeting the needs of students, this dissertation examines the experiences, identity construction, and perceptions of Black male students at a science, technology, engineering, and mathematics (STEM) based early college high school. Using a qualitative case study design, participants were eight Black male upperclassmen enrolled in a STEM early college high school, located on the campus of a four-year university. Data was collected through focus groups and individual interviews and data was analyzed thematically. Findings suggest students in this study have largely positive experiences at their early college high school. Despite some challenges, the early college high school environment helps facilitate scholar identities, and the STEM focus of the school helps students learn more about their strengths and weaknesses. The implications of the research, recommendations for educational stakeholders, and recommendations for future research are discussed.

    Energy is considered both as a disciplinary core idea and as a concept cutting across science disciplines. Most previous approaches studied progressing energy understanding in specific disciplinary contexts, while disregarding the relation of understanding across them. Hence, this study provides a systematic analysis of cross-disciplinary energy learning. On the basis of a cross-sectional study with n = 742 students from grades 6, 8, and 10, we analyze students' progression in understanding energy across biology, chemistry, and physics contexts. The study is guided by three hypothetical scenarios that describe how the connection between energy understanding in the three disciplinary contexts changes across grade levels. These scenarios are compared using confirmatory factor analysis (CFA). The results suggest that, from grade 6 to grade 10, energy understanding in the three disciplinary contexts is highly interrelated, thus indicating a parallel progression of energy understanding in the three disciplinary contexts. In our study, students from grade 6 onwards appeared to have few problems to apply one energy understanding across the three disciplinary contexts. These findings were unexpected, as previous research concluded that students likely face difficulties in connecting energy learning across disciplinary boundaries. Potential reasons for these results and the characteristics of the observed cross-disciplinary energy understanding are discussed in the light of earlier findings and implications for future research, and the teaching of energy as a core idea and a crosscutting concept are addressed.

    Large introductory courses are at a disadvantage in providing personalized guidance and advice for students during the semester. We introduce E2Coach (an Expert Electronic Coaching system), which allows instructors to personalize their communication with thousands of students. We describe the E2Coach system, the nature of the personalized support it provides, and the features of the students who did (and did not) opt-in to using it during the first three terms of its use in four introductory physics courses at the University of Michigan. Defining a 'better-than-expected' measure of performance, we compare outcomes for students who used E2Coach to those who did not. We found that moderate and high E2Coach usage was associated with improved performance. This performance boost was prominent among high users, who improved by 0.18 letter grades on average when compared to nonusers with similar incoming GPAs. This improvement in performance was comparable across both genders. E2Coach represents one way to use technology to personalize education at scale, contributing to the move towards individualized learning that is becoming more attainable in the 21st century.

    Identifying multi-level factors affecting physical activity (PA) levels among adolescents is essential to increasing activity to promote health within this population. This study examines the associations between PA and 11 independent factors among Manitoba high school students. The sample included 31,202 grade 9-12 students who completed the Manitoba Youth Health Survey. Associations between PA and independent factors were examined separately and through multivariate regression. Analyses were stratified by gender. Perception of athletic ability, school location, parental encouragement and number of active friends were strong predictors of activity for moderately active and active males and females. Grade was a significant predictor of PA for females at both levels of activity but only significant for males when comparing active to inactive students. Perception of schoolwork and means of transport were minimally associated with PA. Results highlight the importance of targeting multiple levels of influence to increase PA among youth. Programs should focus on older students, females and those who are inactive or moderately active. In addition, social modeling of PA and increasing self-efficacy around activity should be encouraged.

  8. Physics for computer science students with emphasis on atomic and semiconductor physics

    Garcia, Narciso

    1991-01-01

    This text is the product of several years' effort to develop a course to fill a specific educational gap. It is our belief that computer science students should know how a computer works, particularly in light of rapidly changing tech­ nologies. The text was designed for computer science students who have a calculus background but have not necessarily taken prior physics courses. However, it is clearly not limited to these students. Anyone who has had first-year physics can start with Chapter 17. This includes all science and engineering students who would like a survey course of the ideas, theories, and experiments that made our modern electronics age possible. This textbook is meant to be used in a two-semester sequence. Chapters 1 through 16 can be covered during the first semester, and Chapters 17 through 28 in the second semester. At Queens College, where preliminary drafts have been used, the material is presented in three lecture periods (50 minutes each) and one recitation period per week, 15 weeks p...

    2016-12-01

    The purpose of the current study is to test the self-determination theory (SDT) continuum hypothesis of motivation using latent profile analysis (LPA). A total of 3,220 school students took part in the study. We compared LPA solutions estimated using the four motivation types versus the two higher-order dimensions to assess their degree of correspondence to the SDT continuum hypothesis. To examine the concurrent validity of the profiles, we also verified their associations with three predictors (age, gender, perception of physical education teachers' autonomy-supportive behaviors) and two outcomes variables (perceived competence and intentions to be physically active). The results showed that profiling using the four motivation types provides more differentiated and meaningful description of responses to the Perceived Locus of Causality Scale, compared with profiling using two higher-order factors. In general, the results of the current study were consistent with the SDT continuum hypothesis of human motivation.

    Experiences of racial discrimination have been associated with diverse negative health outcomes among racial minorities. However, extant findings of the association between racial discrimination and alcohol behaviors among Black college students are mixed. The current study examined mediating roles of depressive symptoms and coping drinking motives in the association of perceived racial discrimination with binge drinking and negative drinking consequences. Data were obtained from a cross-sectional study of Black college students attending a predominantly White institution in the northeastern US (N = 251, 66% female, mean age = 20 years). Results from path analysis showed that, when potential mediators were not considered, perceived racial discrimination was positively associated with negative drinking consequences but not frequency of binge drinking. Serial multiple mediation analysis showed that depressive symptoms and in turn coping drinking motives partially mediated the associations of perceived racial discrimination with both binge drinking frequency and negative drinking consequences (after controlling for sex, age, and negative life events). Perceived racial discrimination is directly associated with experiences of alcohol-related problems, but not binge drinking behaviors among Black college students. Affective responses to perceived racial discrimination experiences and drinking to cope may serve as risk mechanisms for alcohol-related problems in this population. Implications for prevention and intervention efforts are discussed.

    This study used a minority stress framework to investigate the relationships between multiple stressors (e.g., general life stress, race related stress, and acculturative stress) and high-risk drinking behaviors in a sample of second-generation Black emerging adult college students across the United States. Participants (n = 148) were recruited from U.S. colleges and universities as part of a large, multiwave cross-sectional study. Findings from this study mirrored those in the extant literature: the positive relationship between race-related stress and high-risk drinking behaviors found in other marginalized groups. However, when all stressors were entered into the model, acculturative stress accounted for significant variance in high-risk drinking behaviors above and beyond general life and race-related stressors in second generation Black emerging adult college students. Findings underscore the need to better understand the influence of acculturative stress on high-risk drinking behaviors among second-generation Black emerging adult college students: an understudied population in both the acculturation and alcohol use literatures. Implications for future research and clinical practice are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Objectives: to evaluate the knowledge, contribution and consumption beverages before, during and after physical activity in a group of physically active university students, to evaluate the body composition, physical activity and energy expenditure during weekly physical activity. Methodology: we carried out a survey of 348 students, 140 female and 208 male, currently attending from the 1st to the 4th year of the Faculty of Sport of the University of Porto. They were appraised through a specific questionnaire and anthropometrical evaluation. Statistical treatment was performed using SPSS, version 13.0 for Windows and Microsoft Excel 2003 for p <0.05. Results: It was verified that 1st and 2nd year students practice and spend more calories with physical activity in a typical week. About 95% of the students consider it necessary to consume beverages before, during and after physical activity. Hydration is mentioned more often by students as justification for the need and consumption of beverages, before, during and after physical activity. Of the students that practiced physical activity, about 85% consume beverages before, during and after physical activity, in at least one sport modality practiced. Discussion: Hydration is for the surveyed students the main justification for the need and consumption of beverages before, during and after physical activity. Water is the students' preferred beverage for consumption during physical activity.

    Enhancing students' academic engagement is the key element of the educational process; hence, research in this area has focused on understanding the mechanisms that can lead to increased academic engagement. The present study investigated the relation between motivation and grades in physical education (PE) employing a 3-year longitudinal design. Three hundred fifty-four Greek high school students participated in the study. Students completed measures of motivation to participate in PE on six occasions; namely, at the start and the end of the school year in the first, second, and third year of junior high school. Students' PE grades were also recorded at these time points. The results of the multilevel growth models indicated that students' PE grades increased over the 3 years and students had better PE grades at the end of each year than at the beginning of the subsequent year. In general, students and classes with higher levels of controlling motivation achieved lower PE grades, whereas higher levels of autonomous motivation were associated with higher PE grades. These findings provide new insight on the associations between class- and individual-level motivation with objectively assessed achievement in PE. © 2014 John Wiley & Sons A/S.

    Despite nearly 200 accredited entry-level physical therapist education programs in the United States that culminate in a doctoral degree, only a paucity of reports have been published regarding the efficacy of peer teaching in gross anatomy. No one has described the usefulness of peer teaching from the viewpoint of the peer teacher. An organized peer teaching method provided by four second-year doctors of physical therapy (DPT) students in a semester course in gross anatomy had a positive impact on the academic performance in gross anatomy of first-year DPT students. The unique feature of the weekly peer teaching sessions was a packet assembled by the second-year peer teachers, which contained diagrams, fill-in-the blank questions, and helpful mnemonic devices. This study surveyed perceptions of first-year DPT students in response to a peer teaching method, using a structured 10-item questionnaire and a five-point Likert scale. Second-year DPT peer teachers provided written reflections about the benefits and challenges of serving as a peer teacher. Results revealed that 13 planned peer-teaching experiences provided by four second-year DPT students were valuable and promoted a firm understanding of anatomical relationships important for the clinical competence of physical therapist students. Moreover, peer teachers acknowledged acquiring clinically desirable teaching, academic, organizational, and time management skills from the experience. As a result, physical therapist educators may wish to consider this model of peer teaching to augment their teaching strategies for a class in gross human anatomy.

    Full Text Available Abstract Background There are limited data on the prevalence rate of Metabolic Syndrome (MetS among college students attending any Historically Black College and University (HBCU, which are mostly attended by young African Americans (AA. We report the prevalence and gender differences in the components of MetS in a sample population from an HBCU campus. Methods Three hundred and seventy six (218 females and 158 males first year college students (average age 19.8 years, attending Kentucky State University, Frankfort with no prior diagnosis of illness participated in the cross sectional study. Anthropometric screenings included measurement of height, weight, waist circumference and body mass index (BMI. The clinical screenings included measurement of blood pressure and determination of fasting lipid and glucose concentrations. The National Cholesterol Education Program’s Adult Treatment Panel III (NCEP ATP III and International Diabetes Federation (IDF definitions for MetS were applied. Statistics: Analysis of variance (ANOVA scores on the Means procedure were used to examine differences between genders for all anthropometric, clinical and biochemical parameters. Fisher’s exact chi-square tests were used to analyze the prevalence of MetS criteria per gender, the number of MetS criteria per BMI category and the prevalence of MetS criteria. Significance was set at p ≤ 0.05 for all tests. Results Prevalence rates for MetS criteria varied depending on the definition used. According to the NCEP ATP definition, 31.4% of the sample population had at least 1 criterion for MetS, while 20.7% had 2 criteria. When IDF definition was applied, 21.3% sample population had 1 criterion and 17.5% had at least two criteria. Prevalence was highest for low levels of high-density lipoprotein cholesterol (37.3% and elevated fasting glucose (22.1%. On the basis of the NCEP ATP and IDF definitions, overall prevalence of MetS in the total sample was 12%, and 9

    Full Text Available Implementing flip-flop teaching in a physics classroom allows students to learn concepts outside of the classroom and apply what they learn in the classroom, working with other students and getting immediate feedback from the instructor. The purpose of this study was to determine the effect of flip-flop teaching in the performance of engineering students in introductory physics particularly in thermal physics. The study employed descriptive and quasi-experimental method to describe and compare the performance of engineering students in thermal physics when grouped according to sex and types of instruction. Three physics classes consisting of 125 sophomore engineering students at the Batangas State University during the second semester of the SY 2013-2014 were handled by the researcher and selected purposively as participants of the study. It was found out that the variation in the performances of male and female students in the conceptual questions, in the problem solving questions, and overall performance in thermal physics are not significantly different. Male and female students have an overall satisfactory performance in thermal physics. The study also revealed that the variation in the performances of the students in the conceptual questions, in the problem solving questions, and overall performance in thermal physics when grouped according to the types of instruction are not significantly different. Engineering students taught in a traditional physics classroom, in a flipped physics classroom, and in an enhanced-flipped physics classroom are more likely to have similar performances in thermal physics.

  9. Physics from geometry: Non-Kahler compactifications, black rings anddS/CFT

    Science.gov (United States)

    Cyrier, Michelle

    The spectrum that arises in four dimensions from compactification of ten dimensional string theory onto six dimensional manifolds is determined entirely by the geometry of the compactification manifold. The massless spectrum for compactifications on Calabi-Yau threefolds, which are Kahler and have complex structure, is well understood. In chapter 2 of this thesis, We study the compactification of heterotic string theory on manifolds that are non-Kahler. Such manifolds arise as a solution for compactifications of heterotic string theory with nonzero H-flux. We begin the study of the massless spectrum arising from compactification using this construction by counting zero modes of the linearized equations of motion for the gaugino in the supergravity approximation. We rephrase the question in terms of a cohomology problem and show that for a trivial gauge bundle, this cohomology reduces to the Dolbeault cohomology of the 3-fold, which we then compute. Another check of string theory is to study the entropy of black holes made in string theory. In Chapter 3, We review the microstate counting of four dimensional black holes made from M theory. We then describe a new solution in five dimensions, the supersymmetric black ring, and describe its microscopic entropy using a similar counting. These agree with the semi-classical Bekenstein-Hawking entropy for these black holes. Finally, one powerful tool for quantum gravity is the holographic duality of string theory in an Anti de Sitter background and a theory living on its conformal boundary. Strominger conjectured a similar duality between quantum gravity in a de Sitter background and the corresponding theory on its boundary. In chapter 4 we examine issues with different representations of the conformal field theory on the boundary for a massive quantum field theory living in the bulk and try to write down a sensible CFT.

    Sports injuries could be highly detrimental to the career of a physical education teacher education (PETE) student. To enable the development of future sports injury prevention programs, sports injuries in 128 first-year academic bachelor PETE students were registered prospectively during one academic year. Common risk factors for sports injuries, taken from the literature, were also evaluated by means of logistic regression analysis. We found an incidence rate of 1.91 and an injury risk of 0.85, which is higher than generally found in a sports-active population. Most injuries involved the lower extremities, were acute, newly occurring injuries, and took place in non-contact situations. More than half of all injuries lead to an inactivity period of 1 week or more and over 80% of all injuries required medical attention. A major part of these injuries happened during the intracurricular sports classes. Few differences were seen between women and men. A history of injury was a significant risk factor (P = 0.018) for the occurrence of injuries, and performance of cooling-down exercises was significantly related to a lower occurrence of ankle injuries (P = 0.031). These data can inform future programs for the prevention of sports injuries in PETE students. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available English for Academic Purposes (EAP and English for Specific Purposes (ESP are developing branches of English as a Foreign Language (EFL instruction in Iran. These branches have a marginal status in the tertiary education, and the Ministry of Science, Research, and Technology’s high commission offers no clear guidance for selecting and developing basic academic instructional materials related to the linguistic or communicative standards expected by teachers (Mazdayasna & Tahririan, 2008. This paper tries to evaluate an ESP textbook written for BSc students of physics entitled, ‘English for the students of physics’, which is prepared by the Center for Studying and Compiling University Books in Humanities (SAMT. The present research was based on qualitative and quantitative research techniques and included two steps. First, internal, external and overall evaluation of the book was carried out based on McDonough & Shaw (1993 model. While conducting the external evaluation of the book, the intended audience, the proficiency level, the context of use, the language, the author's views on language and methodology, the inclusion of a vocabulary list/index, visual features, and the cultural aspects were examined. The internal evaluation included the presentation of the skills, grading and sequencing, discourse skills, listening section, the representation of different learning styles. And in overall evaluation, general suitability of the textbook was assessed. In the second step, six teachers each responded to a 22-item textbook evaluation questionnaire to express their perceptions concerning various aspects of the textbooks. The results revealed the extent of appropriateness of the textbook used by BSc students of physics. Suggestions are offered for the future revision and/or designing the textbooks.

    Full Text Available Aim: The purpose of this study was to determine the relationships among handgrip strength (HGS, dietary pattern, and physical activity level in students from a physical education and sport department. Material and Methods: In this study, 124 men and 77 women aged 18–29 y participated. HGS was evaluated in the dominant hand by using an adjustable handgrip dynamometer and expressed in Newton. Dietary pattern was evaluated by using the Dietary Pattern Index (DPI adapted into the Turkish. Physical activity level was measured by using the short version of the International Physical Activity Questionnaire (IPAQ. Results: The Spearman correlation coefficient showed that HGS positively correlated with IPAQ score (r=0.204, p=0.004, body mass index (r=0.559, p<0.001, and age (r=0.205, p=0.003, but negatively correlated with DPI score (r=−0.179, p=0.01. Conclusion: HGS is a useful, simple, and objective assessment tool for monitoring the physical activity levels and dietary patterns of young subjects.

    Full Text Available The objective of this study was to determine the influence of programmed physical activity on the physical fitness of adolescent students over one school year. The sample consisted of 383 students (age range: 10 to 14 years divided into two groups: 186 cases (96 boys and 90 girls and 197 controls (108 boys and 89 girls. An intervention study with pre- and post-tests was conducted, in which the intervention group was submitted to programmed physical activity, while the control group underwent conventional classes of school physical education. Physical fitness was assessed by sit-and-reach (flexibility, muscle endurance (elbow flexion and extension and aerobic endurance (run/walk, 9 min tests. Motor performance observed in the three tests (flexibility, strength and endurance did not improve from pre-test to post-test in either group, but comparison of the intervention and control groups showed significant improvement in the strength and endurance tests for both genders in the intervention group. Boys of the two groups also showed dominance in the strength and endurance tests. In general, higher muscle strength and cardiorespiratory fitness and lower flexibility were observed for boys when compared to girls, and all parameters increased in the post-test and were higher in the intervention group compared to control A significant difference in flexibility was only observed between genders. With respect to muscle strength, a significant difference was observed between genders and between the intervention and control group after adjustment for age and socioeconomic level. Cardiorespiratory fitness differed significantly between genders and between the intervention and control group.
