    The 12th Annual National Conference of Black Physics Students (NCBPS) was held jointly with the Annual Meeting of the National Society of Black Physicists (NSBP) March 4-8, 1998 in Lexington, Ky. The Proceedings consists of scientific talks and abstracts given by NSBP members and students attending the NCBPS meeting. One joint session of general scientific interest was held, with NCBPS students, NSBP members, and about 75 high school students from the state of Kentucky present. NCBPS session included ''How to get into Graduate School'', ''How to Survive in Graduate School'', and a Panel on ''Opportunities for Physics Graduates.'' The report by AIP: ''Survey of Participants of the 12th Annual NCBPS'' is included in the Proceedings.

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

    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.

  4. Astrophysical Black Holes in the Physical Universe

    Zhang, Shuang-Nan

    2010-01-01

    In this chapter I focus on asking and answering the following questions: (1) What is a black hole? Answer: There are three types of black holes, namely mathematical black holes, physical black holes and astrophysical black holes. An astrophysical black hole, with mass distributed within its event horizon but not concentrated at the singularity point, is not a mathematical black hole. (2) Can astrophysical black holes be formed in the physical universe? Answer: Yes, at least this can be done with gravitational collapse. (3) How can we prove that what we call astrophysical black holes are really black holes? Answer: Finding direct evidence of event horizon is not the way to go. Instead I propose five criteria which meet the highest standard for recognizing new discoveries in experimental physics and observational astronomy. (4) Do we have sufficient evidence to claim the existence of astrophysical black holes in the physical universe? Answer: Yes, astrophysical black holes have been found at least in some galac...

    Objective We compared fruit and vegetable (FV) intake, physical activity (PA), and overweight/ obesity among Black and White females attending two- and four-year colleges. Methods We recruited 24,055 students at six colleges in the Southeast to complete an online survey, yielding 4840 responses (20.1% response rate). The current analyses focused on the 2276 Black and White females. Results Binary logistic regression analyses indicated that recommended FV intake among White females was associated with greater extraversion (Odds Ratio [OR] = 1.05, 95% Confidence Interval [CI] 1.00, 1.11, p = 0.05) and greater conscientiousness (OR = 1.08, CI 1.02, 1.14, p = 0.01), whereas among Black females correlates included greater openness to experience (OR = 1.08, CI 1.01, 1.15, p = 0.03). Ordinal logistic regression analyses indicated that, among White females, greater PA was associated with attending a four-year college (Beta = 0.27, CI 0.01, 0.53, p = 0.04), whereas among Black females, correlates were with younger age (Beta = 0.01, CI 0.17, 0.03, p = 0.003) and greater emotional stability (Beta = 0.07, CI 0.01, 0.13, p = 0.02). Binary logistic regression analyses indicated that, among White females, being overweight or obese was associated with older age (OR = 1.08, CI 1.01, 1.16, p = 0.03), attending a two-year college (OR = 1.62, CI 1.22, 2.16, p = 0.001), and lower satisfaction with life (OR = 0.96, CI 0.94, 0.98, p = 0.002), whereas among Black females, being overweight or obese was associated with older age (OR = 1.87, CI 1.10, 1.28, p < 0.001). Conclusions Identifying factors related to obesity-related factors is critical in developing interventions targeting factors associated with overweight and obesity among Black and White females attending two- and four-year colleges. Moreover, understanding different college settings and the contextual factors associated with overweight/obesity is critical. PMID:25328836

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

    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.

    Intra-group differences among Black undergraduate students remain understudied. To gain a more nuanced understanding of Black student life, we must examine how other social locations, like gender and class, connect to the racialized experiences of Black students. This dissertation argues that for Black students, class and gender, along with race,…

  10. Student Blogging about Physics

    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.

    Astronomy is a very interesting subject for undergraduate students studying physics. In this paper, we report astronomy education for undergraduate students in the Physics Department of Guangzhou University, and how we are teaching astronomy to the students. Astrophysics has been rapidly developing since 1994, when the center for astrophysics was founded. Now, astrophysics has become a key subject in Guangdong Province, and the Astronomy Science and Technology Research Laboratory one of the key laboratories of the Department of Education of the Guangdong Province. Many undergraduate students, working under the tutorship of faculty members completed their thesis at the Center for Astrophysics in Guangzhou.

    Bland-Hawthorn, Joss

    2016-01-01

    For the past decade, the SAIL labs at the University of Sydney have been challenging students with short research projects that elucidate basic principles of physics. These include the development of instruments launched on cubesats, balloons, on telescopes or placed out in the field. This experiment is inspired by the spectacular 2015 discovery of merging black holes with the Laser Interferometric Gravitational-Wave Observatory (LIGO). Students are profoundly inspired by LIGO, and for good reason, but it is challenging to construct a table top demonstration of a gravitational wave observatory. Instead we consider chirps which are remarkable transient phenomena in nature involving both frequency and amplitude modulation, as we can demonstrate with a spinning coin. In the case of the LIGO event, orbital energy is being released as gravitational radiation; for the spinning coin, its spin/orbit energy is being released dissipatively (sound, heat, air viscosity). Our experiment involves a simple device to spin a ...

    Brout, Robert; Parentani, Renaud; Spindel, Philippe

    1995-01-01

    The mechanisms which give rise to Hawking radiation are revealed by analyzing in detail pair production in the presence of horizons. In preparation for the black hole problem, three preparatory problems are dwelt with at length: pair production in an external electric field, thermalization of a uniformly accelerated detector and accelerated mirrors. In the light of these examples, the black hole evaporation problem is then presented. The leitmotif is the singular behavior of modes on the horizon which gives rise to a steady rate of production. Special emphasis is put on how each produced particle contributes to the mean albeit arising from a particular vacuum fluctuation. It is the mean which drives the semiclassical back reaction. This aspect is analyzed in more detail than heretofore and in particular its drawbacks are emphasized. It is the semiclassical theory which gives rise to Hawking's famous equation for the loss of mass of the black hole due to evaporation $dM/dt \\simeq -1/M^2$. Black hole thermodyna...

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

    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.

  5. Applications of hidden symmetries to black hole physics

    Frolov, Valeri, E-mail: vfrolov@ualberta.ca [Institute of Theoretical Physics, Department of Physics University of Alberta, Edmonton, Alberta, T6G 2G7 (Canada)

    2011-02-01

    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.

  6. Effects of student physical attractiveness

    Directory of Open Access Journals (Sweden)

    Krnjajić Stevan B.

    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.

  7. Coexistent physics of massive black holes in the phase transitions

    CERN Document Server

    Zhang, Ming

    2016-01-01

    The coexistent physics of de Rham-Gabada-dze-Tolley (dRGT) massive black holes and holographic massive black holes is investigated in the extended phase space where the cosmological constant is viewed as pressure. Van der Waals like phase transitions are found for both of them. Coexistent curves of reduced pressure and reduced temperature are found to be different from that of RN-AdS black holes. Coexistent curves of reduced Gibbs free energy and reduced pressure show that Gibbs free energy in the canonical ensemble decreases monotonically with the increasing pressure. The concept number density is introduced to study the coexistent physics. It is uncovered that with the increasing pressure, the number densities of small black holes (SBHs) and large black holes (LBHs) change monotonically in the contrary directions till finally reaching the same value at the critical points of the phase transitions. In other words, with the increasing pressure the number density differences between SBHs and LBHs decrease mono...

    Full Text Available A term of health-related physical fitness became topical with four its components: aerobic and/or cardiovascular fitness, body composition, abdominal muscle strength and endurance, and lower back and hamstring flexibility. Complex evaluation of health-related physical fitness and physical activity (PA may show a wider insight in health promotion and disease prevention. The aim of this study was to evaluate physical activity relation to health-related physical fitness in Physiotherapy (PT and Physical Education (PE students. Final study sample consisted of 67 students (46 women and 21 men (aged 21.61 ± 0.71. All participants filled in International Physical Activity Questionnaire. Health-related physical testing included: 1 body composition evaluation, 2 abdominal muscles strength tests, 3 dynamometry, 4 hamstring muscles and m. quadratus lumborum elasticity evaluation tests, 5 bicycle ergometer test (anaerobic threshold, maximal oxygen consumption. Results showed that most students had normal body composition parameters (BMI, body fat, muscle mass, body water in both genders and study programs. Women were less physically active that men, and PA duration was higher in PE students. PT students had higher body composition values, lower cardiorespiratory fitness parameters and lower handgrip strength in both hands than PE students. Greater PA generally implies a higher level of health-related physical fitness. PA significantly positively affects body composition, upper m. rectus abdominisstrength, grip strength and aerobic capacity.

    Doroshkevich, A.G.; Novikov, I.D.

    1978-01-01

    Physical fields and the perturbations of the space-time metric inside a slowly rotating and weakly charged black hole are investigated. It is shown that in the Schwarzschild coordinates r and t for r ..infinity in accordance with the asymptotic law Phi =D/sub 1/t/sup( -2l/+1)+D/sub 2/t/sup( -2l/+3) ln r. Here, D/sub 1/ and D/sub 2/ are constants and l is the multipole order. Fields with nonzero spin (including the gravitational field) increase as r..-->..0 in proportion to a power of r, and not ln r, as in the case of a scalar field. Thus, at a fixed distance r=const from the singularity, the physical fields and all radiatable perturbations of the metric are damped in a power-law fashion with respect to the coordinate t, which is the radial coordinate inside the black hole. Fields of external sources inside the black hole are also considered.

    2003-07-01

    The first meeting of African American physicists was held in 1973 at Fisk University in Nashville, Tennessee, with around 50 Black physicists in attendance. In 1977, this organization was formally established as the National Society of Black Physicists (NSBP) out of a need to address many concerns of African American physicists. During the ensuing years the Conference began to grow and was hosted by different institutions at various geographic locations. This year, the 2003 Annual Conference of the National Society of Black Physicists and Black Physics Students was hosted by Spelman College in Atlanta, Georgia during the weekend of February 12th-15th, 2003. This Conference brought together over 500 African American physics students and working physicists. Also attending were corporate and graduate school recruiters, administrators, professional society representatives and others concerned with the small representation of minorities in the field of physics. The organizers of the Conference contracted with the Statistical Research Center of the American Institute of Physics to conduct a formal evaluative study of the meeting, resulting in this report. The evaluation questionnaire was designed by the organizers of the NSBP conference with input from the Statistical Research Center's staff. It included questions on the students' backgrounds and demographic characteristics, physics research experience, career goals, challenges faced in their academic pursuits, and ratings of various aspects of the conference. The questionnaire was distributed at the conference when the students signed in. Of the 330 students who were registered, roughly 304 attended and were given the four-page questionnaire to complete. Responses were collected on the last night of the conference, with 172 (approximately 57%) returning completed questionnaires. This low response rate could be attributed in part to the fact that respondents were asked to provide possibly sensitive personal

  14. 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

    2017-01-01

    While the gender gap in physics participation is a known problem, practical strategies that may improve the situation are not well understood. As physics education researchers, we draw on evidence to help inform us of what may or may not be working. To this end, physics identity has proven to be a useful framework for understanding and predicting participation in physics. Drawing on data from national surveys of college students, case studies in physics classes, and surveys of undergraduate women in physics, we identify strategies that are predictive of female students' physics identity development from their high school and undergraduate physics experiences. These findings will be discussed as well as future directions for using this research to increase the recruitment of women to physics-related careers. NSF Grant # 1431846.

  13. Black hole feeding and feedback: the physics inside the "subgrid"

    CERN Document Server

    Negri, Andrea

    2016-01-01

    Black holes (BHs) are believed to be a key ingredient of galaxy formation. However, the galaxy-BH interplay is challenging to study due to the large dynamical range and complex physics involved. As a consequence, hydrodynamical cosmological simulations normally adopt sub-grid models to track the unresolved physical processes, in particular BH accretion; usually the spatial scale where the BH dominates the hydrodynamical processes (the Bondi radius) is unresolved, and an approximate Bondi-Hoyle accretion rate is used to estimate the growth of the BH. By comparing hydrodynamical simulations at different resolutions (300, 30, 3 pc) using a Bondi-Hoyle approximation to sub-parsec runs with non-parameterized accretion, our aim is to probe how well an approximated Bondi accretion is able to capture the BH accretion physics and the subsequent feedback on the galaxy. We analyse an isolated galaxy simulation that includes cooling, star formation, Type Ia and Type II supernovae, BH accretion and AGN feedback (radiation...

    Full Text Available Defined theoretical and methodological foundations of physical improvement of students in the interaction of physical and aesthetic education. The interrelation of physical and aesthetic education in accordance with the basic components of physical perfection is conducted. From the standpoint of beauty and culture movements highlighted the following components: physical fitness, health and harmonious physical development. It is found that a person is a certain organic and indissoluble unity of his spiritual and aesthetic, bodily aesthetics and foreign artistic and expressive nature. It is determined that the functional sides of beauty movements form the basis for the development of aesthetic taste. They are a source of aesthetic satisfaction, enjoyment and understanding of beauty in physical exercises and movements of the human body.

  16. 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

  19. Best Approximation to a Reversible Process in Black-Hole Physics and the Area Spectrum of Spherical Black Holes

    CERN Document Server

    Hod, S

    1999-01-01

    The assimilation of a quantum (finite size) particle by a Reissner-Nordström black hole inevitably involves an increase in the black-hole surface area. It is shown that this increase can be minimized if one considers the capture of the lightest charged particle in nature. The unavoidable area increase is attributed to two physical reasons: the Heisenberg quantum uncertainty principle and a Schwinger-type charge emission (vacuum polarization). The fundamental lower bound on the area increase is $4 \\hbar$, which is smaller than the value given by Bekenstein for neutral particles. Thus, this process is a better approximation to a reversible process in black-hole physics. The universality of the minimal area increase is a further evidence in favor of a uniformly spaced area spectrum for spherical quantum black holes. Moreover, this universal value is in excellent agreement with the area spacing predicted by Mukhanov and Bekenstein and independently by Hod.

  20. Student Variability in Learning Advanced Physics

    CERN Document Server

    Sampson, T

    2013-01-01

    Learning of advanced physics, requires a combination of empirical, conceptual and theoretical understanding. Students use a combination of these approaches to learn new material. Each student has different prior knowledge and will master new material at a different pace. However, conventional classroom teaching usually does not accommodate the different learning paces of students. To both, study and address this issue, we developed an iterative Online Learning Machine (iOLM), which provides new learning content to each student based on their individual learning pace and tracks their progress individually. The iOLM learning module was implemented using server side web software (php) to supplement the undergraduate course in electromagnetic waves for majors in physics in their second year. This approach follows the hybrid online learning model. Students had to complete a section of the course using iOLM, which was only presented online. The data obtained for this class showed a wide spread of learning paces, ra...

    2016-08-01

    The Galactic center offers the closest opportunity for studying accretion onto supermassive black holes. The fluctuating source, Sgr A*, is detected across the electromagnetic spectrum and may originate in the accretion flow or jet. Recent general relativistic magneto-hydrodynamic (GRMHD) models indicate that variability can be produced by a tilted inner disk, gravitational lensing of bright spots in the disk by the hole, or particle acceleration in reconnection events. These models produce different flare characteristics, and in particular better characterization of flares may enable us to distinguish between strong and weakly magnetized disks. Disentangling the power source and emission mechanisms of the flares is a central challenge to our understanding of the Sgr A* accretion flow. Following our successful observations of the variability of Sgr A* with IRAC in 2013 and 2014, we propose simultaneous IRAC (4.5 micron) and Chandra (2-10 keV) observations to (1) probe the accretion physics of Sgr A* on event-horizon scales and (2) detect any effect of the object G2 on Sgr A*. Specifically, we propose six additional epochs of observation, each of 24 uninterrupted hours; four in 2017 July and two in 2018 July. In this proposal we request two 24-hour (86.4 ks) Chandra periods, and are requesting another four through the Chandra TAC to have simultaneous X-ray observations in each of the six Spitzer epochs. Independent of this proposal we will also request NuSTAR (3-79 keV), SMA/ALMA/APEX (0.8 mm), and Keck/Magellan NIR (2.2 micron) observations during the IRAC/Chandra epochs. Only such long-duration, continuous, multi-wavelength observations can achieve a comprehensive view of the dominant emission process(es) and quantify the physical properties near the event horizon. Theoretical models are increasing in physical sophistication, and our study will provide essential constraints for the next generation of models.

    2016-06-01

    This study examined the extent to which four essential dimensions of quality physical education teaching (QPET) were associated with healthy levels of physical fitness in elementary school students. Participants were nine elementary PE teachers and 1, 201 fourth- and fifth-grade students who were enrolled in nine elementary schools. The students' physical fitness were assessed using four FITNESSGRAM tests. The PE teachers' levels of QPET were assessed using the Assessing Quality Teaching Rubrics (AQTR). The AQTR consisted of four essential dimensions including Task Design, Task Presentation, Class Management, and Instructional Guidance. Codes were confirmed through inter-rater reliability (82.4% and 84.5%). Data were analyzed through descriptive statistics, multiple R-squared regression models, and independent sample t-tests. The four essential teaching dimensions of QPET were significantly associated with the students' cardiovascular endurance, muscular strength and endurance, and flexibility. However, they accounted for relatively low percentage of the total variance in PACER test, followed by Curl-up test, while explaining very low portions of the total variance in Push-up and Trunk Lift tests. This study indicated that the students who had experienced high level of QPET were more physically fit than their peers who did not have this experience in PACER and Curl-up tests, but not in Push-up and Trunk lift tests. In addition, the significant contribution of the four essential teaching dimensions to physical fitness components was gender-specific. It was concluded that the four teaching dimensions of QPET were significantly associated with students' health-enhancing physical fitness. Key pointsAlthough Task Design, Task Presentation, Class Management, and Instructional Guidance has its unique and critical teaching components, each essential teaching dimensions is intertwined and immersed in teaching practices.Four essential teaching dimensions all significantly

  7. How physics instruction impacts students' beliefs about learning physics

    CERN Document Server

    Madsen, Adrian; Sayre, Eleanor C

    2014-01-01

    Faculty care about their students learning to think like physicists, but often don't assess this because it is not clear how to do so. Physics education researchers have created several surveys to assess one important aspect of thinking like a physicist: what students believe that learning physics is all about. In this meta-analysis, we synthesize the results of 24 studies using the Colorado Learning Attitudes about Science Survey (CLASS) and the Maryland Physics Expectations Survey (MPEX) to answer several questions: (1) How does physics instruction impact beliefs of students? We find that in typical physics classes, these beliefs deteriorate or at best stay the same. There are a few types of interventions, including an explicit focus on model-building and/or developing expert-like beliefs that appear to lead to significant improvements in beliefs. However, because the available data oversamples certain types of classes, it is unclear whether these improvements are actually due to the interventions, or to th...

    1993-01-01

    The Medical College of Georgia's (MCG's) Minority Academic Advising Program (MAAP), which began in 1984, is a supplementary retention program for Black students. This paper describes an evaluation study of the effectiveness of MAAP within the MCG School of Allied Health Sciences (SAHS). The study sample consisted of 89 Black students who enrolled in the SAHS from fall 1978 to fall 1982 (preMAAP period) plus 129 Black students who entered the SAHS from fall 1984 through fall 1988 (MAAP period). The comparison group consisted of all other students who entered the SAHS (n = 1,884) within those same time periods. Using an evaluation design produced by merging a quasi-experimental and a time-series design, the authors found that the MAAP succeeded in increasing both the Black student retention-to-graduation rate and the time-persisted-in-program, to the extent that Black students achieved parity with other SAHS students.

    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. 

  13. Near-horizon physics of evaporating black holes

    CERN Document Server

    Emelyanov, Slava

    2016-01-01

    We study massless scalar theory with a quartic self-interacting term far away from and near to evaporating, spherically symmetric black holes. Moreover, we propose a principle of how to define the physical notion of particle in curved spacetime. We compute one-loop corrections to the self-energy and the coupling constant of scalar field near the horizon in the freely-falling frame. We find that the quartic coupling constant becomes stronger near the horizon. Besides, we employ the covariant Wigner function to compute the local distribution of the outgoing modes at the distance $R \\gg r_H$, where $r_H$ is the horizon size, and discover the result which differs from the Hawking formula. We explain the essence of this discrepancy in detail as well as what this means for local observations. As a by-product we show that the effective density matrix characterising the outgoing modes vanishes in the spatial infinity as $(r_H/R)^2$.

  9. Varying Fine Structure Constant and Black Hole Physics

    CERN Document Server

    Das, S; Das, Saurya; Kunstatter, Gabor

    2003-01-01

    Recent astrophysical observations suggest that the fine structure constant $\\alpha=e^2/\\hbar c$ may be slowly increasing with time. This may be due to an increase of $e$ or a decrease of $c$, or both. In this article, we argue from model independent considerations that this variation should be considered adiabatic. Then, we examine in detail the consequences of such an adiabatic variation in the context of a specific model of quantized charged black holes. We find that the second law of black hole thermodynamics is obeyed, regardless of the origin of the variation, and that interesting constraints arise on the charge and mass of black holes. Finally, we estimate the work done on a black hole of mass $M$ due to the $\\alpha$ variation.

    We investigate the statistical behaviors of 3D hairy black holes in the presence of a scalar field. The present study is made in terms of two relevant parameters: rotation parameter a and B parameter related to the scalar field. More precisely, we compute various statistical quantities including the partition function for non-charged and charged black hole solutions. Using a partition function calculation, we show that the probability is independent of a and B parameters.

    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.

  13. Selected correlates of white nursing students' attitudes toward black American patients.

    Science.gov (United States)

    Morgan, B S

    1983-01-01

    Multivariate analyses were used to examine the relationships between white nursing students' attitudes toward black American patients and variables selected within a theoretical framework of prejudice which included socialization factors and personality-based factors. The variables selected were: authoritarianism and self-esteem (personality-based factors), parents' attitudes toward black Americans, peer attitudes toward black Americans, interracial contact and socioeconomic status (socialization factors). The study also examined the differences in the relationship among white nursing students enrolled in baccalaureate degree, associate degree and diploma nursing programs. Data were collected from 201 senior nursing students enrolled in the three types of nursing programs in Rhode Island during the late fall and winter of 1979-1980. Although baccalaureate degree, associate degree and diploma students were similar in terms of peer attitudes toward black Americans, fathers' attitudes toward black Americans, self-esteem and attitudes toward black American patients, they were significantly different in terms of age, socioeconomic status, mothers' attitudes toward black Americans, interracial contact and authoritarianism. The major findings of this study indicate that the socialization explanation of prejudice is more significant than the personality-based explanation. The variables socioeconomic status, interracial contact and peer attitudes toward black Americans (all socialization variables) accounted for 22.0% of the total variance in attitudes toward black American patients for the total sample of nursing students. However, this relationship was not generalizable across the three different types of nursing programs.

    The discourse on Black boys tends to suggest that Black boys are in complete peril. We begin with evidence that Black boys are excelling in certain contexts (i.e., in certain states, in certain schools, and in certain courses). We then discuss the ways in which the narratives used by parents, teachers, and Black boys themselves may serve to further reinforce views that Black boys are beyond hope. Research on Black parents suggests that they tend to view their sons as vulnerable and have lower expectations for sons than for daughters. Studies of teachers show that they tend to view Black boys as unteachable, as social problems, and as scary. Research on Black boys shows that they are sometimes complicit in supporting these narratives by engaging in negative or ste reotypical behavior. We also include recent research that includes counter-narratives of Black boys. We end with suggestions for future research.

    2004-05-01

    Work more effectively and check solutions as you go along with the text! This Student Solutions Manual is designed for use with Cummings' Understanding Physics. Its primary purpose is to show readers by example how to solve various types of problems given at the end of each chapter in the text. Most of the solutions start from definitions or fundamental relationships and the final equation is derived. This technique highlights the fundamentals and at the same time gives readers the opportunity to review the mathematical steps required to obtain a solution. The mere plugging of numbers into equations derived in the text is avoided for the most part. Readers will learn to examine any assumptions that are made in setting up and solving each problem. Using an interactive strategy, Understanding Physics provides a hands-on introduction to the fundamentals of physics. Built on the foundations of Halliday, Resnick, and Walker's Fundamentals of Physics, 6th Edition, this text represents the latest methods in physics instruction. Incorporating new approaches based on Physics Education Research (PER), this text is designed for courses that use computer-based laboratory tools, and promote Activity Based Physics in lectures, labs, and recitations.

  17. 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

    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. At present galaxies are revolving with speeds proportional to their distances from the cosmic axis of rotation. If present CMBR temperature is 2 : 726 K, present value of obtained angular velocity is 2 : 17 10 Present cosmic mass density and cosmic time are fitted with a ln ( volume ratio parameter. Finally it can be suggested that dark matter and dark energy are ad-hoc and misleading concepts.

    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.

  6. A Note on Physical Mass and the Thermodynamics of AdS-Kerr Black Holes

    CERN Document Server

    McInnes, Brett

    2015-01-01

    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 $E=M/(1-a^2/L^2)^2$; 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: for example, in attempts to "over-spin" AdS-Kerr black holes.

    2011-01-01

    The perspectives of introductory classical physics students can often negatively influence how those students later interpret quantum phenomena when taking an introductory course in modern physics. A detailed exploration of student perspectives on the interpretation of quantum physics is needed, both to characterize student understanding of physics concepts, and to inform how we might teach traditional content. Our previous investigations of student perspectives on quantum physics have indicated they can be highly nuanced, and may vary both within and across contexts. In order to better understand the contextual and often seemingly contradictory stances of students on matters of interpretation, we interviewed 19 students from four introductory modern physics courses taught at the University of Colorado. We find that students have attitudes and opinions that often parallel the stances of expert physicists when arguing for their favored interpretations of quantum mechanics, allowing for more nuanced characteriz...

    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.

  16. The roots of physics students' motivations: Fear and Integrity

    CERN Document Server

    Van Dusen, Ben

    2015-01-01

    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 mot...

    This paper offers an insight into the design structure of physics video hooks that were developed by the Science Education Resource design team in the school of education (SOE) in National University of Ireland, Galway (NUI Galway). A hook, is an instructional technique used to stimulate student attention (Hunter 1994, Lemov 2010), interest (Jewett 2013) and engagement (McCrory 2011, Riendeau 2013). The physics video hooks followed a design framework that is illustrated below by breaking down the centre of gravity (COG) hook. Various design principles and elements embedded within the COG hook are presented with examples and the time they occur within the video. The intention of this article is that the design can be replicated and modified to aid teachers and designers in the development of a multitude of classroom based multimedia resources.

    Science is all around us in everything we do, but science education is not always provided to youngsters who are physically and mentally challenged. The problem is not that most children can`t learn, it is that we are not explaining or modeling to meet each child`s needs. We must rethink our ways of teaching and enthusing. Science can be taught to, and enjoyed by, challenged youth to explain the world around them. The science should be friendly. Scientific vocabulary can be intimidating and everyday words must be used. Increased tactile and visualization methods based on social concepts and sign language can be used to improve science education for physically and mentally challenged students.

    Drake, Carl Timothy

    The purpose of this study was to investigate factors affecting the attitudes that African-American college students have towards introductory college physics. The population targeted for this study consisted of African-American males and females enrolled in introductory college physics classes at an urban public historical black college or university (HBCU) located in the southeastern United States. Nine of the Fennema-Sherman Mathematics Attitude Scales, modified for physics, were used to analyze the attitudes of the 135 participants enrolled in an introductory college physics class. The nine scales used to measure the students' attitudes were Attitude Toward Success in Physics Scale (AS), The Physics as a Male Domain Scale (MD), The Mother Scale (M), The Father Scale (F), The Teacher Scale (T), The Confidence in Learning Physics Scale (C), The Physics Anxiety Scale (A), The Effectance Motivation Scale in Physics (E), and The Physics Usefulness Scale (U). Hypothesis I states that there is a significant difference in the domain scores of African-American college students in the Fennema-Sherman Math Attitudes Scales adapted for physics. It was found using a repeated measures ANOVA that there was a significant difference between the attitudes of African-Americans on the nine attitude scales of the Fennema-Sherman Math Attitude Scales, F(8,992) = 43.09, p .05. Hypothesis III states that there is a statistically significant relationship between attitude towards physics and achievement for African-American students. The students with good attitudes toward physics would have a higher level of achievement. The multiple linear regression analysis revealed that there was a significant relationship between a good attitude toward physics and achievement in the class. The result of the analysis implied that 18.9% of the grade could be explained by the domain scales.

    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.

  10. Refined characterization of student perspectives on quantum physics

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available The perspectives of introductory classical physics students can often negatively influence how those students later interpret quantum phenomena when taking an introductory course in modern physics. A detailed exploration of student perspectives on the interpretation of quantum physics is needed, both to characterize student understanding of physics concepts, and to inform how we might teach traditional content. Our previous investigations of student perspectives on quantum physics have indicated they can be highly nuanced, and may vary both within and across contexts. In order to better understand the contextual and often seemingly contradictory stances of students on matters of interpretation, we interviewed 19 students from four introductory modern physics courses taught at the University of Colorado. We find that students have attitudes and opinions that often parallel the stances of expert physicists when arguing for their favored interpretations of quantum mechanics, allowing for more nuanced characterizations of student perspectives in terms of three key interpretive themes. We present a framework for characterizing student perspectives on quantum mechanics, and demonstrate its utility in interpreting the sometimes contradictory nature of student responses to previous surveys. We further find that students most often vacillate in their responses when what makes intuitive sense to them is not in agreement with what they consider to be a correct response, underscoring the need to distinguish between the personal and the public perspectives of introductory modern physics students.

    There is limited evidence demonstrating the benefits of physical activity with regard to mortality risk or the harms associated with sedentary behavior in black adults, so we examined the relationships between these health behaviors and cause-specific mortality in a prospective study that had a large proportion of black adults. Participants (40-79 years of age) enrolled in the Southern Community Cohort Study between 2002 and 2009 (n = 63,308) were prospectively followed over 6.4 years, and 3,613 and 1,394 deaths occurred in blacks and whites, respectively. Black adults who reported the highest overall physical activity level (≥32.3 metabolic equivalent-hours/day vs. 12 hours/day vs. mortality in blacks and whites. Blacks who reported the most time spent being sedentary (≥10.5 hours/day) and lowest level of physical activity (mortality risk in black adults.

    When garlic is fermented, certain aspects of its bioactivity are changed. Black garlic is a type of fermented garlic used as a food ingredient in Asian cuisine. Black garlic's popularity has spread around the world as it has become a sought-after ingredient used in high-end cuisine. The formulations containing 10% black garlic extract or 10% normal garlic extract showed stable pH, color, precipitation, and organoleptic features, although these characteristics changed slightly. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities of the black garlic formulation were significantly (pgarlic formulation. Mice treated with the black garlic formulation (119.63 μM/g) had significant (pgarlic formulation treated mice (vehicle: 3.46 mM/g vs. black garlic: 5.60mM/g). The formulation containing 10% black garlic extract retained physical stability and had high anti-radical efficiencies. Furthermore, it is possible to suggest that this formulation may be effective in protecting skin from UVB photodamage.

  15. Astrophysical black holes as natural laboratories for fundamental physics and strong-field gravity

    CERN Document Server

    Berti, Emanuele

    2013-01-01

    Astrophysical tests of general relativity belong to two categories: 1) "internal", i.e. consistency tests within the theory (for example, tests that astrophysical black holes are indeed described by the Kerr solution and its perturbations), or 2) "external", i.e. tests of the many proposed extensions of the theory. I review some ways in which astrophysical black holes can be used as natural laboratories for both "internal" and "external" tests of general relativity. The examples provided here (ringdown tests of the black hole "no-hair" theorem, bosonic superradiant instabilities in rotating black holes and gravitational-wave tests of massive scalar-tensor theories) are shamelessly biased towards recent research by myself and my collaborators. Hopefully this colloquial introduction aimed mainly at astrophysicists will convince skeptics (if there are any) that space-based detectors will be crucial to study fundamental physics through gravitational-wave observations.

    Einstein's General Theory of Relativity (GR) successfully describes gravity. The most fundamental predictions of GR are black holes (BHs), but in spite of many convincing BH candidates in the Universe, there is no conclusive experimental proof of their existence using astronomical observations. Are BHs real astrophysical objects? Does GR hold in its most extreme limit or are alternatives needed? The prime target to address these fundamental questions is in the center of our own Galaxy, which hosts the closest and best-constrained supermassive BH candidate in the Universe, Sagittarius A* (Sgr A*). Three different types of experiments hold the promise to test GR in a strong-field regime using observations of Sgr A* with new-generation instruments. The first experiment aims to image the relativistic plasma emission which surrounds the event horizon and forms a "shadow" cast against the background, whose predicted size (~50 microarcseconds) can now be resolved by upcoming VLBI experiments at mm-waves such as the ...

    Full Text Available Background and Objective: Physical inactivity is the fourth leading risk factor for global mortality. Physical inactivity levels are rising in developing countries and Malaysia is of no exception. Malaysian Adult Nutrition Survey 2003 reported that the prevalence of physical inactivity was 39.7% and the prevalence was higher for women (42.6% than men (36.7%. In Malaysia, the National Health and Morbidity Survey 2006 reported that 43.7% (5.5 million of Malaysian adults were physically inactive. These statistics show that physically inactive is an important public health concern in Malaysia. College students have been found to have poor physical activity habits. The objective of this study was to identify the physical activity level among students of Asia Metropolitan University (AMU in Malaysia. Materials and Methods: The study design was a cross sectional survey. A total of 100 participants comprising of 50 male and 50 female students were selected for the study by means of convenience sampling. International Physical Activity Questionnaire (IPAQ short form was used to identify the physical activity level. Results: A greater percentage of males (56% showed high physical activity level than females (24%. In contrast, females showed high percentage of low physical activity level. Students in the age range of 22-25 years depicted more percentage (43.5% of high physical activity level. When comparison of physical activity levels were done among different races, Indian students showed greater percentage (61.8% of high physical activity level. Furthermore, students who were underweight and overweight had 50% and 46.7% of high physical activity levels respectively which are greater than the values observed in normal body weight students. Conclusion: The physical activity level among students was found satisfactory although the percentage of low level of physical activity was found higher in female students.

    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.

    It has been a challenging day. The electricity is off because snow and extreme winds have toppled trees into power lines all across my county. As I've been trying to devise a way to cook dinner, I've been thinking about how equipped we are to handle such emergencies. My husband, who has worked most of the day getting the portable generator going and figuring out how to hook up things to keep us warm and safe, made the comment, "You have to be a MacGyver if you are going to be a homeowner." I began wondering how well we are equipping our students with the ability to figure out how to make things work. We teach the physics principles so they can solve the "book problems," but are we helping them to understand the principles well enough to become real problem solvers? Are they prepared to handle situations when the "usual things" aren't working?

    The Center for Integrated Space Weather Modeling (CISM) holds a two-week Space Weather Summer School for introductory graduate students and space weather professionals to gain a system level understanding of the space environment and the effects of space weather. A typical day in the summer school consists of three morning lectures followed by an afternoon lab session. After the morning lectures, the participants are each asked to submit a question about the mornings topics on a question card. The lecturers then take the time to answer these questions prior to afternoon sessions. In the last 5 years over 1000 such question cards have been collected and cataloged. Despite detailed lectures by experts similar questions appear every year. We have analyzed over 150 questions related to the introductory lectures on solar physics and solar activity. Questions content was categorized using the AGU Index, and question sophistication was categorized using Bloom’s Taxonomy of Educational Objectives. Specific analysis results along with lists of questions will be presented. We hope that these results can be used to improve the lecture and classroom content and allow students to move beyond low level education objectives and ask more sophisticated questions.

    This study was conducted to identify student characteristics and instructional factors that impact student engagement in physical education (PE). Data were derived from the systematic observation of 124 sessions taught by 31 physical educators and the administration of health and PE engagement questionnaires to 2,018 students in grades 5-8. Physical activity was directly affected by student engagement and perceived competence in PE and indirectly affected by students' body image through its association with PE engagement. Multilevel analyses revealed that the proportion of class time devoted to game play was negatively associated with student engagement in PE. Although less frequently used during PE sessions, skill practice was positively associated with student engagement and inactive instruction was negatively associated with student engagement. These effects were particularly pronounced among students with poor competence beliefs. Implications for PE instructional practice and future research are presented.

    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

    2016-01-01

    Student learning in undergraduate physics laboratory courses has garnered increased attention within the PER community. Considerable work has been done to develop curricular materials and pedagogical techniques designed to enhance student learning within laboratory learning environments. Examples of these transformation efforts include the Investigative Science Learning Environment (ISLE), Modeling Instruction, and integrated lab/lecture environments (e.g., studio physics). In addition to improving students' understanding of the physics content, lab courses often have an implicit or explicit goal of increasing students' understanding and appreciation of the nature of experimental physics. We examine students' responses to a laboratory-focused epistemological assessment -- the Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS) -- to explore whether courses using transformed curricula or pedagogy show more expert-like student epistemologies relative to courses using traditional ...

  1. The Importance of High School Physics Teachers for Female Students' Physics Identity and Persistence

    2017-02-01

    Given the historic and continued underrepresentation of women in physics, it is important to understand the role that high school physics might play in attracting female students to physics careers. Drawing on data from over 900 female undergraduates in physics, we examine when these women became interested in physics careers and different sources of recognition (important for physics identity development) that may have affected their choices at certain time points. The results provide optimism since many of these female students, even those not previously intending science careers, began to intend physics careers in high school and recognition from high school physics teachers had a significant effect on predicting these intentions.

  4. 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.

    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 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.

  10. Instructors' Support of Student Autonomy in an Introductory Physics Course

    Hall, Nicholas; Webb, David

    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.

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

    CERN Document Server

    Hamilton, Andrew J S

    2008-01-01

    If you fall into a real astronomical black hole (choosing a supermassive black hole, to make sure that the tidal forces don't 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 & Israel (1990), who called it mass inflation. The 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.

    CERN Document Server

    Wilcox, Bethany R

    2015-01-01

    Student learning in instructional physics labs is a growing area of research that includes studies exploring students' beliefs and expectations about experimental physics. To directly probe students' epistemologies about experimental physics and support broader lab transformation efforts both at the University of Colorado Boulder (CU) and nationally, we developed the Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS). Previous work focused on establishing the accuracy and clarity of the instrument through student interviews and preliminary testing. Ongoing validation efforts include establishing the extent to which student epistemologies as measured by E-CLASS align with other measures of student learning outcomes (e.g., course grades). Here, we report on correlations between final course grades and E-CLASS scores from two semesters of introductory and upper-division lab courses at CU and discuss implications of our findings for the validity of the E-CLASS instrument.

    Irving, Paul W.; Sayre, Eleanor C.

    2016-07-01

    We use the theories of identity statuses and communities of practice to describe three different case studies of students finding their paths through undergraduate physics and developing a physics subject-specific identity. Each case study demonstrates a unique path that reinforces the link between the theories of communities of practice and identity statuses. The case studies also illustrate how students progress and regress in their commitment to their subject-specific identities and their professional identities. The progression/regression is dependent on their willingness to explore different aspects of a physics professional identity and their availability to carry out such exploration. Identity status and future identity crises can manifest in students' behavior in the classroom. Allowing students to engage in more legitimate practices of the physics community, especially in the form of undergraduate research, helps students to explore their opportunities and inform the level of commitment they wish to make to physics.

    2009-11-01

    Over the last two years UBC has completely revamped their introductory course for non-physics majors to present physics in terms of everyday situations and to reinforce connections between classroom physics and real-world phenomena throughout the course. One of the key changes was the incorporation of a final project where groups of students research and present on a topic of their choice related to the course. Students were asked to quantitatively model a real-world situation to make a choice or settle a dispute. At the midpoint and end of the 2008 course students were surveyed with a single transfer problem that tested students' ability to apply physics concepts in real-world contexts. The post-test showed students were more likely to engage in simple (rate)*(time) estimates rather than applying more sophisticated physics principles. Implications for instruction and future work are discussed.

    The purpose of this study was to analyze motivational profiles based on the self-determination theory (Deci and Ryan, 2000) and how these profiles are related to physical education students' enjoyment, state anxiety, and physical activity. The participants, 429 sixth grade students (girls = 216; boys = 213) completed SMS, Sport Enjoyment Scale, PESAS, and Physical Activity Scale. Cluster analyses identified two motivational profiles: 1) the "High motivation profile", in which the students had high intrinsic and extrinsic motivation, and low levels of amotivation, and 2) the "Low motivation profile", in which the students had low intrinsic and extrinsic motivation, and low levels of amotivation. The students in the first cluster enjoyed physical education more and were physically more active. The results revealed that students may be motivated towards physical education lessons both intrinsically and extrinsically, and still experience enjoyment in physical education. Key pointsTWO MOTIVATIONAL PROFILES WERE REVEALED: 1) the "High motivation profile", in which the students had high intrinsic and extrinsic motivation, and low levels of amotivation, and 2) the "Low motivation profile", in which the students had low intrinsic and extrinsic motivation, and low levels of amotivation.The students in the first profile enjoyed physical education more and were physically more active than the students in the second profile.Moreover, the representatives of the "High motivation profile "experienced greater anxiety toward physical education than the representatives of the "Low motivation profile"These findings raised an interesting question whether students engaging in physical education benefit more from the presence of both self-determined and non-self-determined forms of motivation, or are the benefits higher if students are primarily self-determined?

    Full Text Available It is assessed components of a physical fitness of students. It is analyzed the internal and external factors affecting the quality of life for students. The study involved more than 200 students. Found that students represent a category of people with elevated risk factors, which include the nervous and mental tension, constant violations of the food, work and leisure, in their way of life there is a lack of care about their health. It is noted that the existing approaches to promoting physical fitness of students are inefficient and require the development and implementation of brand new contemporary theoretical foundations and practical approaches to the problem of increasing the activity of students. It is proved that sold today in the practice of higher education forms, methods, learning tools do not allow to fully ensure the implementation of approaches to promoting physical fitness of students do not meet the requirements for the preparation of the modern health professional.

    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.

  9. 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.

  10. Introductory physics in biological context: An approach to improve introductory physics for life science students

    Science.gov (United States)

    Crouch, Catherine H.; Heller, Kenneth

    2014-05-01

    We describe restructuring the introductory physics for life science students (IPLS) course to better support these students in using physics to understand their chosen fields. Our courses teach physics using biologically rich contexts. Specifically, we use examples in which fundamental physics contributes significantly to understanding a biological system to make explicit the value of physics to the life sciences. This requires selecting the course content to reflect the topics most relevant to biology while maintaining the fundamental disciplinary structure of physics. In addition to stressing the importance of the fundamental principles of physics, an important goal is developing students' quantitative and problem solving skills. Our guiding pedagogical framework is the cognitive apprenticeship model, in which learning occurs most effectively when students can articulate why what they are learning matters to them. In this article, we describe our courses, summarize initial assessment data, and identify needs for future research.

    Irving, Paul W

    2015-01-01

    We use the theories of identity statuses and communities of practice to describe three different case studies of students finding their paths through undergraduate physics and developing a physics subject-specific identity. Each case study demonstrates a unique path that reinforces the link between the theories of communities of practice and identity statuses. The case studies also illustrate how students progress and regress in their commitment to their subject-specific identities and their professional identities. The progression/regression is dependent on their willingness to explore different aspects of a physics professional identity and their availability to carry out such exploration. Identity status and future identity crises can manifest in students' behavior in the classroom. Allowing students to engage in more legitimate practices of the physics community, especially in the form of undergraduate research, helps students to explore their opportunities and inform the level of commitment they wish to ...

    2010-03-01

    The earliest results in Physics Education Research demonstrated the challenges facing students in understanding the graphical interpretations of slope, derivative, and area under curves in the context of kinematics. As part of ongoing research on mathematical challenges that may underlie documented physics difficulties, we developed and administered a brief survey on single- and multivariable calculus concepts to students within physics and mathematics classrooms at both the introductory and advanced levels. Initial findings among students in multivariable calculus show that as many as one in five students encounter some type of difficulty when asked to rank the slopes at five different points along a single path. We will present further data on the extent to which students in a first semester calculus course and an introductory calculus-based physics course encounter similar challenges.

    Full Text Available The purpose of this study was to compare physical self-concept between physical education and non-physical education university students. 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.

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

    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.

    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.

    Interactive engagement (IE) strategies can be helpful for students learning introductory physics with small group recitations. Less is known about their impact for large lecture-based courses. This study examined student learning and views of physics in a large enrollment course that included IE but no small-group recitation. The questions addressed were: (a) What do students learn about physics and how does this compare to reports for traditional courses?, (b) How do students' views of physics change and how does this compare to reports for traditional courses?, and (c) Which instructional strategies contribute to student outcomes? Data included pre-post FCI scores, classroom examinations during the term, pre-post CLASS scores, and student work, interviews, and open-ended surveys. Findings include a FCI average normalized gain of 0.32, which is high for students with low pre-test score (30% for this group) and instructors new to IE methods. Students' views of physics remained relatively unchanged, which is promising given the typical decline for student views. And instructional strategies as a set, not individual strategies, impacted student outcomes. Findings support the recommendation to adopt IE methods in introductory physics classes, particularly when pre-tests are low.

    Full Text Available Physical skills of female students doing aerobics have been studied. 165 female students aged 17-18 divided into three groups of 55 each have taken part in the experiment. Groups have been trained according to different methods conventionally called 'power aerobics', 'dance aerobics' and 'jump aerobics'. Level of female students' physical skills has been determined by the results of seven tests in the beginning of an academic year and after six-months term. Mathematical treatment of the results has been carried out. The most preferable as to improving physical skills level method has been discovered to be the one aimed on power abilities development method.

    2012-01-01

    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.

  4. Engaging Students In Modeling Instruction for Introductory Physics

    2016-05-01

    Teaching introductory physics is arguably one of the most important things that a physics department does. It is the primary way that students from other science disciplines engage with physics and it is the introduction to physics for majors. Modeling instruction is an active learning strategy for introductory physics built on the premise that science proceeds through the iterative process of model construction, development, deployment, and revision. We describe the role that participating in authentic modeling has in learning and then explore how students engage in this process in the classroom. In this presentation, we provide a theoretical background on models and modeling and describe how these theoretical elements are enacted in the introductory university physics classroom. We provide both quantitative and video data to link the development of a conceptual model to the design of the learning environment and to student outcomes. This work is supported in part by DUE #1140706.

    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 paper 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 attitudes towards the value of physics were probed using a 26-question Likert scale survey over the course of four semesters in an introductory physics course at a comprehensive Jesuit university. We found that students who did not participa...

    The first direct gravitational-wave detection was made by the Advanced Laser Interferometer Gravitational Wave Observatory on September 14, 2015. The GW150914 signal was strong enough to be apparent, without using any waveform model, in the filtered detector strain data. Here those features of the signal visible in these data are used, along with only such concepts from Newtonian and General Relativity as are accessible to anyone with a general physics background. The simple analysis presented here is consistent with the fully general-relativistic analyses published elsewhere, in showing that the signal was produced by the inspiral and subsequent merger of two black holes. The black holes were each of approximately 35 Msun, still orbited each other as close as 350 km apart and subsequently merged to form a single black hole. Similar reasoning, directly from the data, is used to roughly estimate how far these black holes were from the Earth, and the energy that they radiated in gravitational waves.

    2004-03-01

    Helping students appreciate physics education is a formidable task, considering that many students struggle to pass introductory physics courses. Numerous efforts have been made for this undertaking because it is an important step leading to successful learning. In an out-of-classroom academic program, the Supplemental Instruction (SI) Program, we have used the approach, INSPIRE (inquiry, network, skillfulness, perseverance, intuition, reasoning, and effort), to help more students value their experiences in these courses. The method basically includes key elements outlined by experts in physics education [1]. Student responses have been encouraging. Having undergraduates as facilitators in the program is advantageous in promoting principles of physics education. Their training emphasizes tenacity, resourcefulness, understanding, support, and teamwork, i.e. TRUST. We present the organization and focus of the SI Program, and discuss how these improve learning atmosphere and facilitate learning. [1] Edward F. Redish et al, Am J. Phys. 66(3), March 1998.

    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.

[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.

  8. Facilitating high quality student practice in introductory physics

    Science.gov (United States)

    Johnson, Molly

    2001-07-01

    "Practice makes perfect, but only if you do it right." Typical physics students practice extensively through the large quantities of homework they do. But research in introductory physics instruction shows that despite this practice, students often do not learn much in introductory physics. Students often do not focus their practice on the skills (such as concept interpretation, and generating a physical representation of a problem) that they need in order to solve physics problems flexibly and reliably. They often focus their practice instead on simply getting an answer. By omitting practice of important skills, it is likely that those skills will not be learned. This paper identifies communication difficulties between students and between students and instructors as important sources of barriers to achieving high-quality student practice. Some strategies to address communication difficulties in the context of small group in-class problem solving are proposed. A classroom peer-collaborative structure, Supervised Practice, that implements these strategies is described, and the impact of the classroom design on the quality of student practice is investigated.

    We ask how the inclusion of various physical heating processes due to the metal content of gas affect the evolution of massive galaxies and compute a suite of cosmological hydrodynamical simulations that follow these systems and their supermassive black holes. We use a smoothed particle hydrodynamics code with a pressure-entropy formulation and a more accurate treatment of the metal production, turbulent diffusion and cooling rate based on individual element abundances. The feedback models include (1) AGN feedback via high velocity BAL winds and Compton/photoionization heating, (2) explicit stellar feedback from multiple processes including powerful winds from supernova events, stellar winds from young massive stars and AGB stars as well as radiative heating within Stromgren spheres around massive stars, and (3) additional heating effects due to the presence of metals including grain photoelectric heating, metallicity dependent X-ray heating by nearby accreting black holes and from the cosmic X-ray background...

    The Schwarzschild exterior space-time is conformally related to a direct product space-time, M2×S2 , where M2 is a 2 D space-time. This direct product structure arises naturally when considering the wave equation on the Schwarzschild background. Motivated by this, we establish some geometrical results relating to M2 that are useful for black hole physics. We prove that M2 has the rare property of being a causal domain. Consequently, Synge's world function and the Hadamard form for the Green function on this space-time are well defined globally. We calculate the world function and the van Vleck determinant on M2 numerically and point out how these results will be used to establish global properties of Green functions on the Schwarzschild black hole space-time.

  13. 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.

    Ramlo, Susan E.

    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.

    Maries, Alexandru

    2016-01-01

    The Test of Understanding Graphs in Kinematics (TUG-K) is a multiple choice test developed by Beichner to assess students' understanding of kinematics graphs. Many of the items on the TUG-K have strong distractor choices which correspond to introductory students' common difficulties with kinematics graphs. Instruction is unlikely to be effective if instructors do not know these common difficulties and take them into account in their instructional design. We evaluate the performance of first year physics graduate students at identifying introductory students' common difficulties related to kinematics graphs. In particular, for each item on the TUG-K, the graduate students were asked to identify which incorrect answer choice they thought would be most commonly selected by introductory physics students if they did not know the correct answer after instruction in relevant concepts. We used the introductory student data from Beichner's original paper to assess graduate students' knowledge of introductory students'...

    2007-10-01

    A teaching/learning strategy that I have developed over the years for high school students involves the use of photographic images of ordinary objects or scenes to help engage students in the intrigue and beauty of physics. The images help focus classroom discussions, raise curiosity levels among students, and promote creativity of thinking. The photographs can be used in a variety of ways, including assessment, framing discussions, homework assignment, and constructive classroom games. This presentation will describe the various ways photography can be used and will model some techniques. Dozens of ``physics images'' will be shown.

  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

    Welzel, Manuela

    1997-09-01

    During the 1970s, student-centred instruction—that is, “play orientation in physics education” (Spielorientierter Unterricht)—was at the centre of curriculum development at the Institute of Physics Education in Bremen. During the past decade, we investigated this kind of instruction with a particular focus on students' learning processes using a situated cognition perspective. Our research group at the Institute conducted several empirical studies of physics learning for different age groups. The aim of these case studies was to construct detailed understandings of how individual learning processes unfold. On the basis of these studies, we attempt to design physics lessons more effectively than they have been in the past. This paper exemplifies our approach providing information about the theoretical and methodological frameworks, the main outcomes of our studies; and reflections about the possibilities for “more effective” student-centred instruction.

    Beatty, I D; Beatty, Ian D.; Gerace, William J.

    2002-01-01

    Traditional tests are not effective tools for diagnosing the content and structure of students' knowledge of physics. As a possible alternative, a set of term-association tasks (the "ConMap" tasks) was developed to probe the interconnections within students' store of conceptual knowledge. The tasks have students respond spontaneously to a term or problem or topic area with a sequence of associated terms; the response terms and timeof- entry data are captured. The tasks were tried on introductory physics students, and preliminary investigations show that the tasks are capable of eliciting information about the stucture of their knowledge. Specifically, data gathered through the tasks is similar to that produced by a hand-drawn concept map task, has measures that correlate with inclass exam performance, and is sensitive to learning produced by topic coverage in class. Although the results are preliminary and only suggestive, the tasks warrant further study as student-knowledge assessment instruments and sources...

    1990-01-01

    The purpose of this study was to evaluate comparatively the performance of students enrolled in principles of technology and traditional physics classes in Alabama on a physics examination. The subjects included 226 students enrolled in the first year of the principles of technology course at eight pilot school systems in Alabama during the 1988 -89 year as well as 251 students enrolled in randomly selected, intact physics classes from the same school systems. Data were collected utilizing demographic questionnaires developed by the researcher and a physics examination developed by a jury of Auburn University physics professors. Six graduate assistants, including the researcher, administered the examination and the demographic questionnaires in the school systems. Data pertaining to the students' standardized scores were obtained from school counselors. The data were statistically analyzed by a multivariate analysis of variance (MANOVA) test and by a multivariate analysis of partial variance model. Results from the statistical analyses indicate that no significant difference in the two groups of students exist after adjustment for pre-existing differences and selected student and teacher variables. Significant interactions between course and both mathematics and science scores exists. While the physics students' scores were above the grand mean for both mathematics and science and the principles of technology students' scores were below the mean in both cases, the interactions indicate that the relationship between the scores on mathematics and science and course vary more than would be expected by chance for the two groups of students. The most significant conclusion was that the principles of technology course appears to be academically sound and may be the kind of course to successfully bridge the gap between academics and vocational education for a large segment of students.

    Moskal, Barbara M.; Wright, Lyndsey; Taylor, P. C.

    2014-03-01

    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.

  8. Students' network integration vs. persistence in introductory physics courses

    Zwolak, Justyna; Brewe, Eric

    2017-01-01

    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.

    2015-01-01

    Purpose To examine whether intrinsic motivation and behavioral self-regulation are related to physical activity during middle school. Method Structural equation modeling was applied in cross-sectional and longitudinal tests of self-determination theory. Results Consistent with theory, hypothesized relationships 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 was confirmed longitudinally between 6th and 7th grades and between boys and girls, non-Hispanic black and white children and overweight and normal weight students. Conclusions Measures of autonomous motivation (identified, integrated, and intrinsic) were more strongly related to physical activity in the 7th 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, introjected regulation was related to physical activity in 7th 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.

    Full Text Available The primary objective of this research was to adapt the Approaches to Learning Scale developed for the university level by Ellez & Sezgin (2000 to a high school level physics (Approaches to Learning Physics Scale. The secondary objective was to use the adapted scale to examine the approaches of high school students to learning physics and explore how this variable changes according to gender and level of achievement in physics. The adapted scale was applied to a total of 329 high school students in the province of İzmir, Turkey for the purpose of testing the scale's validity and reliability. The reliability coefficient for the whole of the scale was found to be 0.86. The data related to the secondary objective of the research were analyzed using frequencies, percentages, means, standard deviation, two-way multivariate analysis (two-way MANOVA, and follow-up tests. It was determined from the results of the analysis that the students' preference for both a deep and a surface approach to learning physics was slightly above average. It was found the students did not display a significant difference in their approaches to learning according to the gender variable but that there were significant differences between the students' approaches to learning according to the variable of achievement.

  16. 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.

    2009-01-01

    From the interaction of physics and astrophysics we are witnessing in these years a splendid synthesis of theoretical, experimental and observational results originating from three fundametal physical processes. They were originally proposed by Dirac, by Breit and Wheeler and by Sauter, Heisenberg, Euler and Schwinger. The vacuum polarization process in strong electromagnetic field, pioneered by Sauter, Heisenberg, Euler and Schwinger, introduced the concept of critical electric field. It has been searched without success for more than forty years by heavy-ion collisions in many of the leading particle accelerators worldwide. The novel situation today is that these same processes can be studied on a much more grandiose scale during the gravitational collapse leading to the formation of a black hole being observed in Gamma Ray Bursts. This report is dedicated to the scientific race in act. The theoretical and experimental work developed in Earth-based laboratories is confronted with the theoretical interpretat...

  18. Theoretical Physics Implications of the Binary Black-Hole Merger GW150914

    CERN Document Server

    Yunes, Nicolas; Pretorius, Frans

    2016-01-01

    The gravitational-wave observation GW150914 by Advanced LIGO provides the first opportunity to learn about physics in the extreme gravity of coalescing binary black holes. The LIGO/Virgo collaboration has verified that this observation is consistent with General Relativity, constraining the presence of parametric anomalies in the signal. This paper expands this analysis to a larger class of anomalies, highlighting the inferences that can be drawn on non-standard theoretical physics mechanisms that would affect the signal. We find that GW150914 constrains a plethora of mechanisms associated with the generation and propagation of gravitational waves, including the activation of scalar fields, gravitational leakage into large extra dimensions, the variability of Newton's constant, the speed of gravity, a modified dispersion relation, gravitational Lorentz violation and the strong equivalence principle. Unlike other observations that limit these mechanisms, GW150914 is a direct probe of dynamical strong-field gra...

  2. 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

    Cizewski, Jolie A.

    2002-04-01

    The Graduate Program in Physics and Astronomy at Rutgers University involves about 100 graduate students and over 70 faculty members. Research opportunities include experimental and theoretical activities in astronomy, condensed matter, high-energy, and nuclear physics, as well as new initiatives in biological and nano physics and physics education research. Faculty and peer mentors, as well as an academic advisor, are identified for each graduate student upon arrival at Rutgers. All first-year graduate students, without regard to background, are required to participate in the Seminar in Physics, which introduces the graduate students to the breadth of research opportunities, as well as advising students about the academic requirements and preparing for the broad spectrum of future career opportunities. Annual activities in this seminar include sessions at which recent graduates of the program discuss their careers outside of academia or basic research. The course requirements for the Ph.D. in Physics include 2 courses outside of the area of research, one of which can be a course outside of the departmental offerings. Since most students have the option to register for many courses after completing the formal requirements, most students take courses in computer science, engineering, or finance as part of their education. Within one year of advancement to Ph.D. candidacy, students are expected to have the first meeting with their research committee, at which the results of a trial project are presented both orally and in a short written report, and which also serves as a test of the student's aptitude for study in the chosen area and with the chosen advisor. Subsequently, every student is required to meet at least annually with this committee. As a result of these mentoring activities, the time to Ph.D. is now less than 6 years on average. Although about 1/2 of the students assume post-doctoral positions upon completion of the Ph.D., our alumni obtain careers in a

  4. Students' epistemological beliefs, expectations, and learning physics: An international comparison

    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. No significant difference was found between Indian male and female students’ expectations at any level of study. This study shows that most Indian students have nowhere near an expert’s expectations even after instruction, which might affect their

    For many decades now there has been an ongoing debate about the way and extent to which physics ought to be popularized by appealing to a student's every day experience. Part of this debate has focused on how textbooks, a major factor shaping students' education, ought to be written and presented. I examine the background, passages, and problems of two examples drawn from the special genre of ``Household Physics'' textbooks which were published largely between 1910 and 1940. The pedagogy of applying or relating physics to the everyday experience engenders values defining how and by whom science is to be applied. These books are particularly evocative, as well, of the extent to which gender can be tied to differing everyday experiences and the consequences therefore of using experiential examples. Using popular science textbooks can alienate students by drawing an implicit division between the reader and the practicing scientist.

    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. Key PointsThe purpose of this study was to analyze perceived barriers to physical activity in the university students.The results showed that not having enough time was the most important barrier for not participating in physical activity among our samples.This study with relatively small sample must be considered as pilot study for related studies in the future.

    This paper presents a new strategy to be implemented in Bulgarian schools in teaching physics and astronomy to students with impaired hearing at grades 7 (13-year-old students) and 8 (14-year-old students). The strategy provides effective education for students with hearing disabilities in mainstream schools as well as for those attending specialized schools. A multimedia CD has been developed, which offers a large number of basic terms from the corresponding fields of physics and astronomy, accompanied by textual explanation and various illustrations. The terms are explained in Bulgarian, Bulgarian Sign Language and English. This multimedia product can be used by children with hearing disabilities, as well as by children without disorders.

    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.

    The questions about the origin and type of cosmic particles are not only fascinating for scientists in astrophysics, but also for young enthusiastic high school students. To familiarize them with research in astroparticle physics, the Pierre Auger Collaboration agreed to make 1% of its data publicly available. The Pierre Auger Observatory investigates cosmic rays at the highest energies and consists of more than 1600 water Cherenkov detectors, located near Malarg\\"{u}e, Argentina. With publicly available data from the experiment, students can perform their own hands-on analysis. In the framework of a so-called Astroparticle Masterclass organized alongside the context of the German outreach network Netzwerk Teilchenwelt, students get a valuable insight into cosmic ray physics and scientific research concepts. We present the project and experiences with students.

    In its second year of an educational research collaboration on the convergence between physical environment, pedagogical methods, student attainment and academic performance, CASPER along with the Region 12 Education Service Center and Huckabee Inc. have completed their initial quantitative study. This project examined the impact of the physical environment on student engagement, employing a flexibility construct and examination of teacher mobility and places of centeredness. Data analysis showed a positive correlation between student engagement and classroom flexibility for two locations having statistically significant differences in flexibility scores. The research is now being extended to examine a laboratory setting (in this case, a complex plasma lab) where the results will be used to enhance student work efficiency while also increasing safety within the lab. Details will be discussed in this presentation. Region 12 and Huckabee funding is gratefully acknowledged.

    We describe an initiative at the University of Bonn, where the students develop and perform a 2 hour physics show for school classes and the general public. The show is entertaining and educational and is aimed at children aged 10 and older. For the physics students this is a unique experience to apply their knowledge at an early stage and gives them the chance to develop skills in the public presentation of science, in front of 520 people per show. We have extended the activity to put on an elementary particle physics show for teenagers. Furthermore, local high schools have picked up the idea; their students put on similar shows for fellow students and parents. We would be interested in hearing about related activities elsewhere.

  13. Investigating Students' Reflective Thinking in the Introductory Physics Course

    Boudreaux, Andrew

    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.

  15. Exploring mass-scaling physics and outflow geometry in accreting black holes

    Connors, Riley Michael Thomas

    2017-01-01

    One of the main tasks facing studies of black hole accretion in both black hole X-ray binaries (XRB) and Active Galactic Nuclei (AGN) is to break spectral model-fitting degeneracies. We explore two methods of simultaneous spectral modelling to reduce these degeneracies: (a) simultaneous fitting of XRBs and AGN, and (b) folding in timing properties in a novel way to better understand the outflow evolution of XRBs during outburst.It is a long-standing idea that AGN are scaled up versions of XRBs, such that the physics of accretion cares only about accretion rate, and not the black hole mass. We show that this principle of scale-invariance may provide us with a way to break degeneracies in broadband spectral modelling of both XRBs and AGN, focusing primarily on low-luminosity sources where degeneracies are more prevalent. We simultaneously model the broadband spectra of the two most quiescent (LX ~ 10-9 LEdd) accreting black holes on opposite ends of the mass scale, the XRB A0620-00 and Sgr A*, the Galactic centre supermassive black hole (during bright flaring). We use an outflow-dominated model capable of reproducing the broadband spectrum from radio to X-ray frequencies, co-evolving parameters that are representative of the mass-scaling properties. Such a method reduces the degeneracies in our model parameters, contributing to answering this question regarding the dominant emission mechanisms.We adopt a similar technique to investigate how spatial parameters of an XRB outflow can be better understood by tracking our model parameters as a function of the XRB variability properties during outburst, focusing in particular on GX 339-4. I shall discuss how utilising a novel characterisation of the timing properties of XRBs allows us to do this in a simple, quantitative way.We are currently developing our models further to incorporate the most up-to-date disc reflection routines in order to describe the jet/disc interaction more accurately. I shall briefly discuss this

    This study examined the behavioral beliefs of physical education (PE) teachers about teaching students with disabilities in their general PE (GPE) classes and to identify the factors that contribute to their beliefs. A total of 195 PE teachers from a region in eastern China were surveyed. Results of the Physical Educators' Attitudes Toward Teaching Individuals With Disabilities-III survey indicate that although some teachers felt that including students with disabilities in GPE classes provides benefit for them, they were concerned about the practical difficulties of teaching students with disabilities in GPE classes, the lack of support, and the possible rejection of students with disabilities by their peers. Moreover, the behavioral beliefs of teachers vary according to the disability conditions of the students. Results show that there is no significant effect of demographic factors on the beliefs of PE teachers. Quality of experience predicts positive beliefs. The study has important implication for teacher training, provision of equipment, and support from teacher assistants.

    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.

  18. 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

  20. Theoretical physics implications of the binary black-hole mergers GW150914 and GW151226

    Yunes, Nicolás; Yagi, Kent; Pretorius, Frans

    2016-10-01

    The gravitational wave observations GW150914 and GW151226 by Advanced LIGO provide the first opportunity to learn about physics in the extreme gravity environment of coalescing binary black holes. The LIGO Scientific Collaboration and the Virgo Collaboration have verified that this observation is consistent with Einstein's theory of general relativity, constraining the presence of certain parametric anomalies in the signal. This paper expands their analysis to a larger class of anomalies, highlighting the inferences that can be drawn on nonstandard theoretical physics mechanisms that could otherwise have affected the observed signals. We find that these gravitational wave events constrain a plethora of mechanisms associated with the generation and propagation of gravitational waves, including the activation of scalar fields, gravitational leakage into large extra dimensions, the variability of Newton's constant, the speed of gravity, a modified dispersion relation, gravitational Lorentz violation and the strong equivalence principle. Though other observations limit many of these mechanisms already, GW150914 and GW151226 are unique in that they are direct probes of dynamical strong-field gravity and of gravitational wave propagation. We also show that GW150914 constrains inferred properties of exotic compact object alternatives to Kerr black holes. We argue, however, that the true potential for GW150914 to both rule out exotic objects and constrain physics beyond general relativity is severely limited by the lack of understanding of the coalescence regime in almost all relevant modified gravity theories. This event thus significantly raises the bar that these theories have to pass, both in terms of having a sound theoretical underpinning and reaching the minimal level of being able to solve the equations of motion for binary merger events. We conclude with a discussion of the additional inferences that can be drawn if the lower-confidence observation of an

    Full Text Available This study aimed to improve the physical fitness of the non-physical education students by using prophylactic physiotherapy elements. The study tried to confirm the following hypothesis: If prophylactic physiotherapy is applied correctly to the non-physical education students, according to their assessed level of fitness, their health is improved, and a prevention of various disorders is achieved. Thirty students were comprised in the study (males and females, aged between 21 and 24; for 15 of them we created and applied an adapted program of aerobic exercises, over the course of the second semester of the academic year, 2012-2013. The other 15 subjects participated in the physical education classes, following the regular syllabus. The Ruffier and the Hettinger tests were applied to both groups of students, initially and finally. After the final tests, we observed that the students in the experimental group have improved their fitness after the application of the aerobic exercise programs, while the control group students remained at the same level.

This cross-sectional research study was carried out on the 176 university students. As a data-collecting device, the Physical activity assessment questionnaire (FADA was used. An additional questionnaire was administered to obtain Body Mass Index (BKİ and demographic data. 8.5% (15 of students were obese (Body Mass Index ≥ 25. The mean age, gender, where the student lived , family type, social guarantee and income were not statistically different between subjects who were normal weight and subjects who were obese (p>0.05. There was difference between normal weight and obese groups from the perspective of FADA stair, FADA sport, FADA travel and FADA total variables, in physical activity measurement (p<0.05. When the obese groups were categorized according to their total physical activity score which was obtained from FADA, 83.5 % (15 of them found as sedentary. A negatively significant correlation was found between BKİ and FADA stair, sport, travel, total scores (r= -0.223- 0.285, p<0.05. According to Binary logistic regression analysis, it was found that the FADA sport and total decreased, as the value of BKİ increased (p<0.02. Proper weight and higher physical activity levels should be promoted among university students. Additionally, schools should provide opportunities for young people to participate in a wider range of physical activities that address their individual needs while promoting the health benefits of engaging in regular exercise.

  4. 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

    In this era of unprecedented attention from the White House and Congress, the STEM community must rise to the challenge of recruiting and retaining students to achieve the mandate of producing one million additional college graduates with degrees in STEM. However, the number of students choosing to pursue and persist with physics as a degree has had a stagnated growth rate when compared to other STEM fields, and some institutions are experiencing dramatic shifts in the demographics of the students entering their programs. The development of a subject-specific identity is a strong influence on students' persistence in a discipline and is a productive lens from which to understand the stagnated growth rate of physics majors and how to support a shift in student demographics. In this presentation, ongoing research is presented that aims to understand identity development in STEM with a focus on the transition from physics student to physicist. Community development and exposure to authentic practice are established as crucial factors that contribute to the development of a professional identity. How these findings can be implemented into course design is discussed with an outline of the P3 learning environment. The P3 learning environment blends the regular focus of reform-based teaching practices on deep conceptual understanding with a focus on students obtaining understanding through engagement with authentic scientific practices. By establishing and studying learning environments similar to P3 we can further explore the development of subject-specific identity while also developing effective teaching practices.

    Youth violence is a critical public health problem across races/ethnicities in the United States. Although the differential association between substance use and physical aggression has been empirically proven, no tests have assessed the moderating effects of sociocultural differences in such associations. The purpose of this study is to test the moderating impact of race/ethnicity-as an indicator of sociocultural differences--on the associations between substance use and adolescent aggression, by conducting a validity assessment of a physical aggression measure for high school students with emphasis on Hispanics and other minorities. A cross-sectional, secondary data analysis of the 2007 national Youth Risk Behavior Survey, with a representative sample of all U.S. high school students, was conducted. Contingency table and chi-square test evaluated the statistical relationship between substance use (alcohol, marijuana, either, or both) and self-reports of physical aggression, race/ethnicity, age, and sex of the respondent. Three logistic regression analyses assessed the effect of race/ethnicity on the likelihood of reporting physical aggression by overall substance use and type of substance use. Statistical significant associations were found between physical aggression and alcohol and/or marijuana use. The self-report of substance use (marijuana or alcohol) and alcohol use significantly increased the likelihood of physical aggression across races/ethnicities, highest among racial/ethnic minorities (Blacks > Hispanic > Others > Whites). The differential impact of substance use on physical aggression was confirmed, and such impact was moderated by the sociocultural context (race/ethnicity) of the adolescent. In-depth validity assessments are needed to confirm this study's predictive validity findings.

The daily intervention consisted of skills development (25 min, vigorous PA (VPA, 35 min, and strengthening/stretching (20 min components. Body composition was measured by dual-energy X-ray absorptiometry. Results. Following the intervention, the ATT exhibited an increase in moderate-to-vigorous PA and a significant reduction in BMI, fat mass, and %BF compared to the control group. A significant association among the intervention energy expenditure and changes in body composition and CV fitness was observed only in the ATT group. Conclusion. An after-school PA program of sufficient length and intensity can promote healthy changes in body composition and fitness levels in black boys who attend at least 3 days/week.

    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.

    Caballero, Marcos D; Doughty, Leanne; Pollock, Steven J

    2014-01-01

    At the upper-division level, many of students' primary learning opportunities come from working long, complex back-of-the-book style problems, and from trying to develop an understanding of the underlying physics through solving such problems. Some of the research at the upper-division focuses on how students use mathematics in these problems, and what challenges students encounter along the way. There are a number of different and diverse studies on students' use of mathematics in the upper-division. These typically utilize one of two broad approaches, with some researchers primarily seeking out and addressing challenges students face, and others working chiefly to unpack students' in-the-moment reasoning. In this paper, we discuss both approaches briefly, and then discuss research efforts that strive to connect these two approaches in order to make sense of students' use of mathematics as well as to uncover particular challenges that students encounter. These recent efforts represent a small step towards sy...

  19. A tensorial description of particle perception in black-hole physics

    Barbado, Luis C; Garay, Luis J; Jannes, Gil

    2016-01-01

    In quantum field theory in curved backgrounds, one typically distinguishes between objective, tensorial, quantities such as the Renormalized Stress-Energy Tensor (RSET) and subjective, non-tensorial, quantities such as Bogoliubov coefficients which encode perception effects associated with the specific trajectory of a detector. In this work we propose a way to treat both objective and subjective notions on an equal tensorial footing. For that purpose, we define a new tensor which we will call the Perception Renormalized Stress-Energy Tensor (PeRSET). The PeRSET is defined as the subtraction of the RSET corresponding to two different vacuum states. Based on this tensor we can define perceived energy densities and fluxes. The PeRSET helps to have a more organized and systematic understanding of various results in the literature regarding quantum field theory in black hole spacetimes. We illustrate the physics encoded in this tensor by working out various examples of special relevance.

    The detection of neutrinos from massive stellar collapses can teach us a lot not only about source objects but also about microphysics working deep inside them. In this study we discuss quantitatively the possibility to extract information on the properties of dense and hot hadronic matter from neutrino signals coming out of black-hole-forming collapses of non-rotational massive stars. Based on our detailed numerical simulations we evaluate the event numbers for SuperKamiokande with neutrino oscillations being fully taken into account. We demonstrate that the event numbers from a Galactic event are large enough not only to detect it but also to distinguish one hadronic equation of state from another by our statistical method assuming the same progenitor model and non-rotation. This means that the massive stellar collapse can be a unique probe into hadron physics and will be a promising target of the nascent neutrino astronomy.

  2. Astrophysical Orientation of Physics Students through Seminars in Rural Mexico

    Chatterjee, T. K.; Vera, D.; Fourier, R.; Pedroza, A.

    In a developing country, science teaching is oriented towards subjects having a bearing on national utility and development of technological skills; thus it is necessary to justify astronomy education. This is conveniently done by introducing an astrophysically oriented course for physics students and connecting it with a sanctioned astronomical project. We have done this at the Faculty and Institute of Science of the Puebla University. This university, in collaboration with other universities and institutes has a (sanctioned) satellite program --SATEX.I (whose objective is to launch communication satellites for data relay in the UHF band and experiment in the K-alpha band). The students of this project (from our university) were in urgent need of a course on "Astrodynamics" and so we opened one; but we invited students (with appropriate knowledge of physics and mathematics) from the entire science faculty, and extended the scope of the course to introduce astrophysical concepts to science students. We also prepared a series of very comprehensive introductory lecture notes, computer-printed them and distributed them (free) amongst students. We have been successful in getting a substantial number of very good students.

    1999-01-01

    Acoustic propagation in a moving fluid provides a conceptually clean and powerful analogy for understanding black hole physics. As a teaching tool, the analogy is useful for introducing students to both General Relativity and fluid mechanics. As a research tool, the analogy helps clarify what aspects of the physics are kinematics and what aspects are dynamics. In particular, Hawking radiation is a purely kinematical effect, whereas black hole entropy is intrinsically dynamical. Finally, I discuss the fact that with present technology acoustic Hawking radiation is almost experimentally testable.

    Soil organic matter is one of the largest reservoirs in global carbon cycle, and black carbon (BC) represents a chemical resistant component. Black C plays an important role in global climate change. Generally considered recalcitrant due to high aromaticity, the reactive surface and functional groups of BC are crucial for carbon sequestration in soils. Mineral sorption and physical protection is an important mechanism for BC long term stabilization and sequestration in environments. Previous studies on mineral protection of BC were limited to analysis techniques in two-dimensions, for example, by SEM, TEM, and NanoSIMS. Little is known about the scope of organo-mineral association, the in-situ distribution and forms of minerals, and the ultimate interplay of BC and minerals. The aim of this study is to investigate the three-dimensional interaction of organic C and minerals in submicron scale using synchrotron-based Transmission X-ray Microcopy (TXM) and Fourier-Transform Infrared Spectroscopy (FTIR). Abundant poorly-crystallined nano-minerals particles were observed. These short-range-order (SRO) minerals also aggregate into clusters and sheets, and form envelops-like structures on the surface of BC. On top of large surface contact area, the intimate interplay between BC and minerals reinforces the stability of both organic C and minerals, resulting from chemical bonding through cation bridging and ligand exchange. The mineral protection enhances BC stabilization and sequestration and lowers its bioavailability in environment. The results suggest that mineral physical protection for BC sequestration may be more important than previous understanding.

    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 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.

    Meaningful comparison of physical self-concept among racial or ethnic groups requires that the measurement instruments used have equivalent measurement properties. We tested the factorial validity and invariance of the Physical Self-Description Questionnaire (PSDQ) among Black (n = 658) and White (n = 479) adolescent girls in the 12th grade. Construct validity was examined by estimating correlations between PSDQ subscales and external criteria (physical activity, physical fitness, body mass index [BMI], and participation in sports). The hypothesized 11-factor model demonstrated adequate overall fit in both groups. Comparison of nested models supported the between-group invariance of the overall factor structure. Convergent and discriminant evidence for construct validity was supported by the pattern of correlations with the external criteria. The results indicate that a meaningful comparison of PSDQ scores can be made between Black and White girls in the 12th grade and that valid inferences from PSDQ scores can be made about specific aspects of physical self-concept. Despite lower levels of physical activity, sport participation, and fitness and higher BMI, Black girls had similar self-esteem and higher physical self-concept and perceived appearance compared to White girls.

  7. Students' Attitudes and Enrollment Trends in Physics and Engineering

    Banjong, Delphine

    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.

    We give a qualitative analysis based on the interaction with students from different communities that how the social and cultural values can deeply affect the young population and their priorities in life. Also the educational strategies and teaching methods have to be changed according to the demographic situations and the needs of corresponding students. Most of the known facts in this regard are accepted as realities however, some further modifications are still required and some of them have to be taken back to fulfil the requirements of the individual subjects. We specially focus on physics students and describe about their requirements based on their background.

    For the past seven years at the end of each spring semester, the ASU Society of Physics Students has journied throughout Texas for a week long outreach to various K-12 schools. During the week long outreach effort, a variety of physics demonstrations were presented to over 1300 students, teachers and school administrators. The goal of this public engagement activity is to both encourage younger students to consider following STEM related career paths and to spark an overall interest in science. Demonstrations focused on several aspects of physics. For the 2011 Road Tour, we paid special homage to the 100th anniversary of Ernest Rutherford's postulation of his model of the atom by explaining his results and their implications in 1911. In addition to adding several new demonstrations, the tradition of having a custom laser light show for each school was continued. As always, the fan favorite ``Nitrogen Bomb'' and a new nitrogen thunder cloud were added to our grand finales. The team, consisting of two faculty advisors and eleven students, was able to leave lasting impressions in a new and exciting way across central Texas.

    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.

    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.

    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.

    Hintz, A. R.

    2009-05-01

    The Black Rock Desert volcanic field, located in west-central Utah, consists of ~30 small-volume monogenetic volcanoes with compositions ranging from small rhyolite domes to large basaltic lava flow fields. The field has exhibited bimodal volcanism for > 9 Ma with the most recent eruption of Ice Springs volcano ˜ 600 yrs ago. Together this eruptive history along with ongoing geothermal activity attests to the usefulness of a hazard assessment. The likelihood of a future eruption in this area has been calculated to be ˜ 8% over the next 1 Ka (95% confidence). However, many aspects of this field such as the explosivity and nature of many of these eruptions are not well known. The physical volcanology of the Tabernacle Hill volcano, suggests a complicated episodic eruption that may have lasted up to 50 yrs. The initial phreatomagmatic eruptions at Tabernacle Hill are reported to have begun ~14 Ka. This initial eruptive phase produced a tuff cone approximately 150 m high and 1.5 km in diameter with distinct bedding layers. Recent mapping and sampling of Tabernacle Hill's lava field, tuff cone and intra-crater deposits were aimed at better constraining the eruptive history, physical volcanology, and explosive energy associated with this eruption. Blocks ejected during the eruption were mapped and analyzed to yield minimum muzzle velocities of 60 - 70 meters per second. These velocities were used in conjunction with an estimated shallow depth of explosion to calculate an energy yield of ˜ 0.5 kT.

    The Galactic center offers the closest opportunity for studying accretion onto a supermassive black hole. The fluctuating source, Sgr A*, is detected across the electromagnetic spectrum and its flux may originate in either the accretion flow or a jet, or both. Disentangling the power source and emission mechanisms of the flares is a central challenge to our understanding of the Sgr A* accretion flow. Recent general relativistic magneto-hydrodynamic (GRMHD) models indicate that variability can be produced by a tilted inner disk, gravitational lensing of bright spots in the disk by the hole, or particle acceleration in reconnection events. These models produce different flare characteristics, and better characterization of flares may enable us to distinguish between strong and weakly magnetized disks. Following our successful Spitzer observations of the variability of Sgr A* in 2013 and 2014, we have undertaken a program of simultaneous IRAC (4.5 micron) and Chandra (2-10 keV) observations to (1) probe the accretion physics of Sgr A* on event-horizon scales and (2) detect any effect of the object G2 on Sgr A*. In addition, several ground-based observatories participated in the campaigns, at wavelengths including radio, sub-mm, and the near-infrared. We will present initial Spitzer/Chandra results from the two 24-hour epochs in 2016 July. Only such long-duration, continuous, multi-wavelength observations can achieve a comprehensive view of the dominant emission process(es) and quantify the physical properties near the event horizon.

    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 European Particle Physics Outreach Group (EPPOG) developed the Masterclass in 2004 to bring particle physics to high school classrooms in Europe. They put real data on a website (http://wyp.teilchenphysik.org/mc.htm) from the Large Electron-Positron (LEP) collider at CERN. Students analyze this data and draw conclusions at their schools. They then compare their results with those found at other schools in Masterclass live video conferences hosted by CERN over the internet. In March 2004, six students at Ward Melville High School on Long Island were sponsored by QuarkNet and Brookhaven National Laboratory to become the first U.S. team to participate in the EPPOG Masterclass. The Ward Melville group was positive about the experience and their results tracked well with those of their colleagues in the video conference from high schools in Greece, Slovakia, and Poland.

    [This paper is part of the Focused Collection on Gender in Physics.] Active-learning approaches to teaching introductory physics have been found to improve student learning and affective gains on short-term outcomes [S. Freeman et al., Proc. Natl. Acad. Sci. U.S.A. 111, 8410 (2014)]; however, whether or not the benefits of active learning impact women to the same degree as men has been a point of concern [A. Madsen, S. B. McKagan, and E. C. Sayre, Phys. Rev. ST Phys. Educ. Res. 9, 020121 (2013)]. Further, the long-term impacts of active-learning experiences are also understudied. At Florida International University, a Hispanic-majority institution, we have implemented Modeling Instruction (MI) and the Integrated Science Learning Environment (ISLE) in introductory physics classes for the past decade. In this empirical paper, we report on a longitudinal investigation of student performance and persistence in upper level physics courses after having previously experienced MI or ISLE in their introductory physics courses, and disaggregate students by gender. Using survival analysis methods, we find women who declare physics as a major are more likely than men to graduate with a physics degree. Women are also just as likely as men to pass through the upper division courses, with the highest failure risk for both men and women occurring in the first semester of upper-division course taking. These results reinforce the need to expand considerations of performance outcomes to be longitudinal to measure the effectiveness of the entire physics experience.

  8. Undergraduate physics course innovations and their impact on student learning

    Iverson, Heidi Louise

    Over the last several decades, the efficacy of the traditional lecture-based instructional model for undergraduate physics courses has been challenged. As a result, a large number of reform-oriented instructional innovations have been developed, enacted, and studied in undergraduate physics courses around the globe---all with the intended purpose of improving student learning. This thesis satisfies the need for a comprehensive synthesis of the effectiveness of these course innovations by analyzing: (1) the types of innovations that have been enacted, (2) the impact of these innovations on student learning, and (3) the common features of effective innovations. An exhaustive literature search for studies published after 1990 on undergraduate physics course innovations yielded 432 articles which were then coded with respect to the characteristics of the innovations used as well as the methodological characteristics of the studies. These codes facilitated a descriptive analysis which characterized the features of the pool of studies. These studies were then meta-analyzed in order to evaluate the effect of innovations on student learning. Finally, a case-study analysis was conducted in order to identify the critical characteristics of effective innovations. Results indicate that most innovations focus on introductory mechanics and use some combination of conceptually oriented tasks, collaborative learning, and technology. The overall effect of course innovations has been positive, but with the caveat that a large number of studies suffer from poor methodological designs and potential threats to validity. In addition, over half of the studies had to be eliminated from the meta-analysis because they did not report the data necessary for an effect size to be calculated. Despite these limitations the results of the meta-analysis indicated that there was one innovation which had particularly high effect sizes---Workshop/Studio Physics---an innovation which involves an

    Comparing black hole thermodynamics with the axiomatic formulation of thermodynamics for laboratory systems, it is found that some basic assumptions (required by experimental facts) in laboratory thermodynamics do not hold for black hole thermodynamics. Hence, at present, it is not obvious whether black hole thermodynamics retains some crucial theorems of laboratory thermodynamics (e.g. Carnot's theorem, increase of entropy by arbitrary adiabatic process, and uniqueness of entropy) whose proofs use the basic assumptions which do not hold for black holes. This paper aims to clarify such nontriviality in black hole thermodynamics, and propose a suitable set of basic assumptions in black hole thermodynamics, which are regarded as the rigorous foundation of black hole thermodynamics as phenomenology.

    When education researchers describe newly developed curricular materials, they typically concentrate on the research base behind their design, and the efficacy of the final products, but do not highlight the initial stages of creating the actual materials. With the aim of providing useful information for faculty engaged in similar projects, we describe here our development of a set of in-class tutorials for advanced undergraduate electrodynamics students, and discuss factors that influenced their initial design and refinement. Among the obstacles to be overcome was the investigation of student difficulties within the short time frame of our project, and devising ways for students to engage in meaningful activities on advanced-level topics within a single 50-minute class period. We argue for a process that leverages faculty experience and classroom observations, and present several guidelines for tutorial development and implementation in upper-division physics classrooms.

    2009-09-01

    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%.

    2016-01-01

    "Self-diagnosis tasks" aim at fostering diagnostic behavior by explicitly requiring students to present diagnosis as part of the activity of reviewing their problem solutions. We have been investigating the extent to which introductory physics students can diagnose their own mistakes when explicitly asked to do so with different levels of scaffolding support provided to them. In our study in an introductory physics class with more than 200 students, the recitation classes were split into three different experimental groups in which different levels of guidance were provided for performing the self-diagnosis activities. We present our findings that students' performance was far from perfect. However, differences in the scaffolding in the three experimental groups (i.e. providing a correct solution and a self-diagnosis rubric) noticeably affected the resulting diagnosis.

  14. Physics students' approaches to learning and cognitive processes in solving physics problems

    Bouchard, Josee

    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

    Full Text Available IntroductionConsiderable evidence exists that little cigars are popular among African American adolescents and young adults who smoke. However, few studies have been published on the use of this tobacco product by young blacks in the United States. This research investigated little-cigar use among students at a historically black university in the southeastern United States.MethodsAs a follow-up to a survey on tobacco use among freshmen that revealed unexpectedly high rates of little-cigar use, 3 focus groups were conducted with current or former smokers of little cigars. Topics included preferred brands of little cigars, preference for little cigars over cigarettes, social contexts for smoking little cigars, perceived health risks of smoking little cigars relative to smoking cigarettes, and thoughts about quitting.ResultsFocus group participants preferred little cigars to cigarettes for various reasons, among them taste, smell, a better “buzz,” social purposes, status, and perceptions that smoking little cigars is less addictive and less harmful than smoking cigarettes. Opinions on health risks varied; some participants believed that health risks can be reduced by removing the inner liner of little cigars.ConclusionUse of little cigars should be addressed in tobacco research, use prevention, and use cessation efforts, targeting students at historically black colleges and perhaps other young African Americans. Results also suggest that clear distinctions should be made among cigarettes, little cigars, and cigars, and that tobacco use prevention and cessation programs should debunk myths that little cigars are a safe alternative to cigarettes. Study findings should be confirmed and elucidated through additional research.

  19. Examining the Relationship between Physical Models and Students' Science Practices

    Science.gov (United States)

    Miller, Alison Riley

    Scientists engage with practices like model development and use, data analysis and interpretation, explanation construction, and argumentation in order to expand the frontiers of science, so it can be inferred that students' engagement with science practices may help them deepen their own science understanding. As one of three dimensions on which the Next Generation Science Standards is built, science practices are recognized as an important component of science instruction. However, the contexts in which these practices happen are under-researched. Furthermore, research on science practices among students tends to focus on one or two practices in isolation when, in reality, students and scientists tend to engage with multiple overlapping practices. This study focused on identifying and characterizing multiple science practices as eighth and ninth-grade Earth Science students participated in a small group collaborative problem solving activity both with and without the use of a physical model. This study found a range of sophistication in the observed science practices as well as a relationship between the frequency of those practices and the accuracy of the groups' outcomes. Based on this relationship, groups were assigned to one of three categories. Further analysis revealed that model use varied among the three categories of groups. Comparisons across these three group categories suggest that there may be a bootstrapping relationship between students' engagement with science practices and the development of their content understanding. This metaphor of bootstrapping is used to represent how students may develop deeper science content understanding through engagement with science practices and concurrently develop greater facility with science practices as they learn science content. Implications are presented for curriculum designers, teachers and teacher educators. These include recommendations for curriculum design that encourage structured opportunities for

    Students' attitudes and approaches to problem solving in physics can greatly impact their actual problem solving practices and also influence their motivation to learn and ultimately the development of expertise. We developed and validated an attitudes and approaches to problem solving (AAPS) survey and administered it to students in the introductory physics courses in a typical large research university in the US. Here, we discuss the development and validation of the survey and analysis of the student responses to the survey questions in introductory physics courses. The introductory physics students' responses to the survey questions were also compared with those of physics faculty members and physics PhD students. We find that introductory students are in general less expert-like than the physics faculty members and PhD students. Moreover, on some AAPS survey questions, the responses of students and faculty have unexpected trends. Those trends were interpreted via in

    Exacting excellence equally from university students around the globe can be accomplished by providing all students with necessary background tools to achieve mastery of their courses, even if those tools are not part of normal content. As instructors we hope to see our students grasp the substance of our courses, make mental connections between course material and practical applications, and use this knowledge to make informed decisions as citizens. Yet many educators have found that students enter university-level introductory courses in mathematics, science and engineering without adequate academic preparation. As part of a FIPSE-funded project at the University of Wyoming, the instructors of the Physical Geology course have taken a new approach to tackling the problem of lack of scientific/mathematic skills in incoming students. Instead of assuming that students should already know or will learn these skills on their own, they assess students' needs and provide them the opportunity to master scientific literacies as they learn geologic content. In the introductory geology course, instructors identified two categories of literacies, or basic skills that are necessary for academic success and citizen participation. Fundamental literacies include performing simple quantitative calculations, making qualitative assessments, and reading and analyzing tables and graphs. Technical literacies are those specific to understanding geology, and comprise the ability to read maps, visualize changes through time, and conceptualize in three dimensions. Because these skills are most easily taught in lab, the in-house lab manual was rewritten to be both literacy- and content-based. Early labs include simple exercises addressing literacies in the context of geological science, and each subsequent lab repeats exposure to literacies, but at increasing levels of difficulty. Resources available to assist students with literacy mastery include individual instruction, a detailed

    Full Text Available The aim of this study was to compare the reasons of sport participation, studying physical education and their expectations about future of physical education students according to different department. Research performed on totally 318 students (123 students from Physical Education and Sports Instruction Department/PESID, 130 students from Coaching Department/CD and 65 students from Sports Management Department/SMD from Cukurova University, Faculty of Physical Education in Turkey. Students answered the survey sheet which is designed by researcher. As a result; it is found that being an athlete, do sport as a leisure activity and meeting new people were statistically more important reasons to sport participation for CD and SMD students than for PESID students. In addition, become more successful in sport and studying sport at the university were statistically more effective reasons to studying physical education for CD and SMD students than for PESID students. Also CD students have statistically higher expectation from future than SMD and PESID students with become academic and studying abroad.

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

    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.

    2014-01-01

    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.

  8. Student reasoning about ratio and proportion in introductory physics

    Science.gov (United States)

    Boudreaux, Andrew

    2012-02-01

    To many students, introductory physics must seem a fast-moving parade of abstract and somewhat mysterious quantities. Most such quantities are rooted in proportional reasoning. Using ratio, physicists construct the force experienced by a unit charge, and attach the name electric field, or characterize a motion with the velocity change that occurs in a unit time. While physicists reason about these ratios without conscious effort, students tend to resort to memorized algorithms, and at times struggle to match the appropriate algorithm to the situation encountered. Although the term ``proportional reasoning'' is prevalent, skill in reasoning with these ratio quantities is neither acquired nor applied as a single cognitive entity. Expert ability seems to be characterized by the intentional use of a variety of components, or elements of proportional reasoning, by a fluency in shifting from one component to another, and by a skill in selecting from among these components. Based on this perspective, it is natural to expect students to develop proportional reasoning ability in fits and starts as various facets are acquired and integrated into existing understandings. In an ongoing collaboration between Western Washington University, New Mexico State University, and Rutgers, we are attempting to map the rich cognitive terrain of proportional reasoning, and to use our findings to guide the design of instruction that develops fluency. This talk will present a provisional set of proportional reasoning components, along with research tasks that have been developed to measure student ability along these components. Student responses will be presented as evidence of specific modes of thinking. The talk will conclude with a brief outline of our approach to improving student understanding.

  9. Student evaluations of their physics teachers: Evaluative bias and its relationship to classroom pedagogy and students' career aspirations

    2013-04-01

    Using data collected from a nationally-representative sample of college students, the evaluation of high school physics teachers by their students is examined. Confirming earlier work, student evaluations (of both male and female students) exhibit bias with respect to the gender of their teacher. Pedagogical practices that impact student evaluations are explored, but these factors do not change the gender bias effect. We also consider how this evaluative bias is affected by students' career intentions. Grouping students according to their career intentions (e.g. physics majors, engineering majors, and health/medical science majors) shows that physics and engineering majors exhibit this bias to the same extent as the general population, but health/medical science majors exhibit a bias with nearly twice the size as average. The implications of this research for our understanding of physics culture regarding stereotypes and students' gendered expectations of teacher behavior is discussed. This work was supported by NSF Grant # 1036617.

    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...

  11. Carrying the physics of black-hole binary evolution into gravitational-wave models for pulsar-timing arrays

    Taylor, Stephen; Sampson, Laura; Simon, Joseph

    2016-03-01

    There has recently been significant interest in how the galactic environments of supermassive black-hole binaries influences the stochastic gravitational-wave background signal from a population of these systems, and in how the resulting detection prospects for pulsar-timing arrays are effected. Tackling these problems requires us to have robust and computationally-efficient models for the strain spectrum as a function of different environment influences or the binary orbital eccentricity. In this talk we describe a new method of constructing these models from a small number of synthesized black-hole binary populations which have varying input physics. We use these populations to train an interpolant via Gaussian-process regression, allowing us to carry real physics into our subsequent pulsar-timing array inferences, and to also correctly propagate forward uncertainties from our interpolation.

    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.

    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{sub 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.)

    2014-01-01

    Physics education research (PER) is a rapidly growing area of PhD specialization. In this article we examine the trajectories that led respondents into a PER graduate program as well as their expected future trajectories. Data were collected in the form of an online survey sent to graduate students in PER. Our findings show a lack of visibility of PER as a field of study, a dominance of work at the undergraduate level, and a mismatch of future desires and expectations. We suggest that greater exposure is needed so PER is known as a field of inquiry for graduates, that more emphasis should be placed on research beyond the undergraduate level, and that there needs to be stronger communication to graduate students about potential careers.

    Thompson, John; Christensen, Warren; Mountcastle, Donald

    2010-03-01

    In work on student understanding of concepts in advanced thermal physics, we are exploring student understanding of the mathematics required for productive reasoning about the physics. By analysis of student use of mathematics in responses to conceptual physics questions, as well as analogous math questions stripped of physical meaning, we find evidence that students often enter upper-level physics courses lacking the assumed prerequisite mathematics knowledge and/or the ability to apply it productively in a physics context. Our focus is in two main areas: interpretation of P-V diagrams, requiring an understanding of integration, and material properties and the Maxwell relations, involving partial differentiation. We have also assessed these mathematical concepts among students in multivariable calculus. Calculus results support the findings among physics students: some observed difficulties are not just with transfer of math knowledge to physics contexts, but seem to have origins in the understanding of the math concepts themselves.

    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.

  8. Implementing a Flip-Flop Teaching Model in Thermal Physics for Engineering Students

    2015-11-01

    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.

    2016-01-01

    The aim of this study was to determine which disruptive behaviors occur most often in physical education (PE) classes, and to identify the existence of a pattern of behavior that leads to this disruptive behavior. With this in mind, we analyzed five PE sessions taken by pupils at different elementary school in the region of Murcia. The total sample size was 96 students aged between 10 and 13. Data was recorded using an observation instrument (a combination of a field format and a categorical system) and was then analyzed using the "HOISAN" software tool, with a sequential analysis and polar coordinates being conducted. The results of the study revealed that disruptive behaviors (52 %) occur more frequently than non-relevant behaviors (48 %), the most common of them being disinterested behavior (29 %), followed by indiscipline (15 %), with no statistically significant differences being detected in violent behavior. As regards patterns of behavior, disinterested behavior is stimulated by "no eye contact", "middle distance", "inside the task", "no use of material", "giving orders" and "registering of activities", while indiscipline is stimulated by "no eye contact", "far distance", "outside the task", "use of material", "grouping in pairs" and "preparation of material". In conclusion, it can be stated that disruptiveness is far more common in physical education sessions, affects the development of sessions and has a negative impact on student learning. A solution to this problem should therefore be sought immediately in order to ensure quality education.

  10. Racial/Ethnic differences in the educational expectations of adolescents: does pursuing higher education mean something different to latino students compared to white and black students?

    Turcios-Cotto, Viana Y; Milan, Stephanie

    2013-09-01

    There are striking disparities in the academic achievement of American youth, with Latino students being a particularly vulnerable population. Adolescents' academic expectations have been shown to predict educational outcomes, and thus are an important factor in understanding educational disparities. This article examines racial/ethnic differences in the future expectations of adolescents, with a particular focus on how expectations about higher education may differ in frequency and meaning for Latino youth. Participants included 375 urban ninth-grade students (49 % Latino, 23 % White, 22 % Black, and 6 % other; 51 % female) who gave written descriptions of how they pictured their lives in 5 years. Responses were subsequently coded for content and themes. Results demonstrate that Latino youth were less likely to picture themselves attending college when compared to Black and White youth, and more likely to hold social goals, such as starting their own family. Ethnic/racial differences also were found in the themes present in responses, with Latino and Black students more likely than White students to describe individuation and materialistic goals, and to give more unrealistic responses. For Latino youth only, higher education goals were associated significantly with individuation themes. In addition, for Latino youth, adolescents who wished to pursue higher education reported more depressive symptoms and emotional distress than those who did not picture going to college, whereas the opposite pattern was evident for Black and White youth. These differences may reflect cultural values, such as familismo. Practice implications include the importance of culturally tailoring programs aimed at promoting higher education.

    2013-12-01

    We analyze the development in students’ understanding of fundamental principles in the context of learning a current interdisciplinary research topic—soft matter—that was adapted to the level of high school students. The topic was introduced in a program for interested 11th grade high school students majoring in chemistry and/or physics, in an off-school setting. Soft matter was presented in a gradual increase in the degree of complexity of the phenomena as well as in the level of the quantitative analysis. We describe the evolution in students’ use of fundamental thermodynamics principles to reason about phase separation—a phenomenon that is ubiquitous in soft matter. In particular, we examine the impact of the use of free energy analysis, a common approach in soft matter, on the understanding of the fundamental principles of thermodynamics. The study used diagnostic questions and classroom observations to gauge the student’s learning. In order to gain insight on the aspects that shape the understanding of the basic principles, we focus on the responses and explanations of two case-study students who represent two trends of evolution in conceptual understanding in the group. We analyze changes in the two case studies’ management of conceptual resources used in their analysis of phase separation, and suggest how their prior knowledge and epistemological framing (a combination of their personal tendencies and their prior exposure to different learning styles) affect their conceptual evolution. Finally, we propose strategies to improve the instruction of these concepts.

    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.

    2015-01-01

    Kerr black holes with scalar hair are solutions of the Einstein-Klein-Gordon field equations describing regular (on and outside an event horizon), asymptotically flat black holes with scalar hair (arXiv:1403.2757). These black holes interpolate continuously between the Kerr solution and rotating boson stars in D=4 spacetime dimensions. Here we provide details on their construction, discussing properties of the ansatz, the field equations, the boundary conditions and the numerical strategy. Then, we present an overview of the parameter space of the solutions, and describe in detail the space-time structure of the black holes exterior geometry and of the scalar field for a sample of reference solutions. Phenomenological properties of potential astrophysical interest are also discussed, and the stability properties and possible generalizations are commented on. As supplementary material to this paper we make available numerical data files for the sample of reference solutions discussed, for public use.

    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

  4. In the physics class: university physics students' enactment of class and gender in the context of laboratory work

    Science.gov (United States)

    Danielsson, Anna T.

    2014-06-01

    This article explores how the doing of social class and gender can intersect with the learning of science, through case studies of two male, working-class university students' constitutions of identities as physics students. In doing so, I challenge the taken-for-granted notion that male physics students have an unproblematic relation to their chosen discipline, and nuance the picture of how working-class students relate to higher education by the explicit focus on one disciplinary culture. Working from the perspective of situated learning theory, the interviews with the two male students were analysed for how they negotiated the practice of the physics student laboratory and their own classed and gendered participation in this practice. By drawing on the heterogeneity of the practice of physics the two students were able to use the practical and technological aspects of physics as a gateway into the discipline. However, this is not to say that their participation in physics was completely frictionless. The students were both engaged in a continuous negotiation of how skills they had learned to value in the background may or may not be compatible with the ones they perceived to be valued in the university physicist community.

  7. Problematizing a general physics class: Understanding student engagement

    Science.gov (United States)

    Spaid, Mark Randall

    This research paper describes the problems in democratizing a high school physics course and the disparate engagement students during class activities that promote scientific inquiry. Results from the Learning Orientation Questionnaire (Martinez, 2000) guide the participant observations and semi-formal interviews. Approximately 60% of the participants self-report a "resistant" or "conforming" approach to learning science; they expect to receive science knowledge from the teacher, and their engagement is influenced by affective and conative factors. These surface learners exhibit second order thinking (Kegan, 1994), do not understand abstract science concepts, and learn best from structured inquiry. To sustain engagement, conforming learners require motivational and instructional discourse from their teacher and peers. Resisting learners do not value learning and do not engage in most science class activities. The "performing" learners are able to deal with abstractions and can see relationships between lessons and activities, but they do not usually self-reflect or think critically (they are between Kegan's second order and third order thinking). They may select a deeper learning strategy if they value the knowledge for a future goal; however, they are oriented toward assessment and rely on the science teacher as an authority. They are influenced by affective and conative factors during structured and guided inquiry-based teaching, and benefit from motivational discourse and sustain engagement if they are interested in the topic. The transforming learners are more independent, self-assessing and self-directed. These students are third order thinkers (Kegan, 1994) who hold a sophisticated epistemology that includes critical thinking and reflection. These students select deep learning strategies without regard to affective and conative factors. They value instructional discourse from the teacher, but prefer less structured inquiry activities. Although specific

  18. A curricular frame for physics education: Development, comparison with students' interests, and impact on students' achievement and self-concept

    Science.gov (United States)

    Häussler, Peter; Hoffmann, Lore

    2000-11-01

    This article presents three interlinked studies aimed at: (1) developing a curricular frame for physics education; (2) assessing the students' interest in the contents, contexts, and activities that are suggested by that curricular frame; and (3) developing a curriculum that is in line with that frame and measuring its cognitive and emotional effects on students. The curricular frame was developed by adopting the Delphi technique and drawing on the expertise of 73 persons selected according to specified selection criteria. Interest data of some 8000 students and information of the presently taught physics curriculum were sampled longitudinally as well as cross-sectionally in various German Länder (states) by questionnaire. The third study comprised 23 experimental and 7 control classes. As a result of the comparison between the features of the curricular frame, the interest structure of students, and the current physics curriculum, there is a remarkable congruency between students' interest in physics and the kind of physics education identified in the Delphi study as being relevant. However, there is a considerable discrepancy between students' interest and the kind of physics instruction practiced in the physics classroom. Regression analysis revealed that students' interest in physics as a school subject is hardly related to their interest in physics, but mainly to the students' self-esteem of being good achievers. The data strongly suggest physics be taught so that students have a chance to develop a positive physics-related self-concept and to link physics with situations they encounter outside the classroom. A curriculum based on these principles proved superior compared to a traditional curriculum.

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

    Science.gov (United States)

    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

    Full Text Available Algae are a group of organisms, Thallophytes, containing specific bioactive compounds (i.e. brominated phenols, heterocyclic oxygen compounds, sterols, terpenes, polysaccharides. Their excessive growth has negative consequences on marine organisms; on the other hand, they have a crucial role in food, pharmaceuticals, cosmetics, agriculture. In this paper were studied the main physical-chemical characteristics correlated with the biological specificity of three species of multicellular algae, Enteromorpha intestinalis and Ulva rigida (green, Ceramium rubrum (red, frequently encountered along the Romanian Black Sea coast. Generally mixtures of thallophytes algae from the Black Sea were collected, processed and characterized. Density, pH, conductivity, anions, loss on drying, ash, total nitrogen, protein, lipids, carbohydrates, carotenoids were determined. The results emphasized the possibility of using these marine resources as biofertilizer in agriculture.

    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

    2011-01-01

    The spatial distribution of matter in clusters of galaxies is mainly determined by the dominant dark matter component, however, physical processes involving baryonic matter are able to modify it significantly. We analyse a set of 500 pc resolution cosmological simulations of a cluster of galaxy with mass comparable to Virgo, performed with the AMR code RAMSES. We compare the mass density profiles of the dark, stellar and gaseous matter components of the cluster that result from different assumptions for the subgrid baryonic physics and galaxy formation processes. First, the prediction of a gravity only N-body simulation is compared to that of a hydrodynamical simulation with standard galaxy formation recipes, then all results are compared to a hydrodynamical simulation which includes thermal AGN feedback from Super Massive Black Holes (SMBH). We find the usual effects of overcooling and adiabatic contraction in the run with standard galaxy formation physics, but very different results are found when implement...

  5. Adapting a theoretical framework for characterizing students' use of equations in physics problem solving

    Rebello, Carina M.; Rebello, N. Sanjay

    2012-02-01

    Previous studies have focused on the resources that students activate and utilize while solving a given physics problem. However, few studies explore how students relate a given resource such as an equation, to various types of physics problems and contexts and how they ascertain the meaning and applicability of that resource. We explore how students view physics equations, derive meaning from those equations, and use those equations in physics problem solving. We adapt Dubinsky and McDonald's description of APOS (action-process-object-schema) theory of learning in mathematics, to construct a theoretical framework that describes how students interpret and use equations in physics in terms of actions, processes, objects, and schemas. This framework provides a lens for understanding how students construct their understanding of physics concepts and their relation to equations. We highlight how APOS theory can be operationalized to serve as a lens for studying the use of mathematics in physics problem solving.

    We use a numerical code to consider the nonlinear processes arising when a Reissner-Nordström black hole is irradiated by an exotic scalar field ( modeled as a free massless scalar field with an opposite sign for its energy-momentum tensor). These processes are quite different from the processes arising in the case of the same black hole being irradiated by a pulse of a normal scalar field. In our case, we did not observe the creation of a spacelike strong singularity in the T region of the space-time. We investigate the antifocusing effects in the gravity field of the exotic scalar field with the negative energy density and the evolution of the mass function. We demonstrate the process of the vanishing of the black hole when it is irradiated by a strong pulse of an exotic scalar field.

    We consider the nonlinear processes arising when a Reissner-Nordstrom black hole is irradiated by an exotic scalar field beam using a special numerical code. These processes are quite different from the processes arising in the case of the irradiation of the same black hole by a beam of a normal scalar field. In our case, we did not observe the creation of a space-like strong singularity in the T-region of the space-time nor the conversion of the Cauchy horizon into a weak singularity of the special kind. We investigate the antifocusing effects in the gravity field of the exotic scalar field with the negative energy density and the evolution of the mass function. We demonstrate the process of vanishing of the black hole when it is irradiated by a strong beam of an exotic scalar field.

  8. Observing Supermassive Black Holes across cosmic time: from phenomenology to physics

    Merloni, A

    2015-01-01

    In the last decade, a combination of high sensitivity, high spatial resolution observations and of coordinated multi-wavelength surveys has revolutionized our view of extra-galactic black hole (BH) astrophysics. We now know that supermassive black holes reside in the nuclei of almost every galaxy, grow over cosmological times by accreting matter, interact and merge with each other, and in the process liberate enormous amounts of energy that influence dramatically the evolution of the surrounding gas and stars, providing a powerful self-regulatory mechanism for galaxy formation. The different energetic phenomena associated to growing black holes and Active Galactic Nuclei (AGN), their cosmological evolution and the observational techniques used to unveil them, are the subject of this chapter. In particular, I will focus my attention on the connection between the theory of high-energy astrophysical processes giving rise to the observed emission in AGN, the observable imprints they leave at different wavelengths...

  9. Students, language, and physics: Discourse in the science classroom

    Science.gov (United States)

    Kowalski, Susan Marie

    Women and minorities do not enter science professions at rates consistent with their populations (Rosser, 2000). A variety of theoretical frameworks and associated interventions have been cited in the literature; yet, the gender and racial gaps remain. Theoretical frameworks and the associated interventions to promote the success of women and minorities in the sciences have primarily been one dimensional: they address issues of Self (associated with experiential and psychoanalytical framings) or Language (categorical and deconstructive framings) (Grumet & Stone, 2000). Furthermore, research in science education with few exceptions (Hanson, 2004), has failed to address race and gender through an intersectional analysis. This study investigates the inclusion and exclusion of girls and minorities in the sciences by examining the connections between Self and Language in physics group work conversations. Critical Discourse Analysis was used to explore the connections between Self and Language. Eight students in two groups were the focus of the study. Transcription of conversations and coding of transcripts with students' subject positions, genres, and registers provided evidence of the reflexivity of Self and Language. Furthermore, the study demonstrated how group discourse and power imbalances within groups serve to simultaneously facilitate and constrain learning opportunities and learning itself.

    Kapucu, Serkan; Bahçivan, Eralp

    2015-05-01

    Background: There are some theoretical evidences that explain the relationships between core beliefs (i.e., epistemological beliefs) and peripheral beliefs (self-efficacy in learning) in the literature. The close relationships of such type of beliefs with attitudes are also discussed by some researchers. Constructing a model that investigates these relationships by considering theoretical and empirical evidences can empower researchers to discuss these relationships more comprehensively. Purpose: The purpose of this study is to explore the relationships among Turkish high school students' scientific epistemological beliefs, self-efficacy in learning physics and their attitudes toward physics. Sample: A total of 632 high school students participated in this study; however, 269 female and 229 male (a total of 498) high school students' data were used. Design and methods: Three distinct instruments that measure scientific epistemological beliefs, self-efficacy in learning physics and attitudes toward physics were combined into a unique questionnaire form and it was distributed to high school students. To explore the relationships among these variables, structural equation modeling was used. Results: The results showed that scientific epistemological belief dimensions uncovered by the nature of knowing (source and justification) significantly and positively related to both self-efficacy in learning physics and attitudes toward other important physics dimensions. Additionally, self-efficacy in learning physics significantly and positively predicted attitudes toward multiple physics dimensions (importance, comprehension and requirement). However, epistemological belief dimensions related to the nature of knowledge (certainty and development) did not have significant impact on self-efficacy in learning physics or attitudes toward physics. Conclusions: This study concludes that there are positive and significant relationships among Turkish high school students' scientific

  15. 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.

  18. Evidence for Low Black Hole Spin and Physically Motivated Accretion Models from Millimeter VLBI Observations of Sagittarius A*

    CERN Document Server

    Broderick, Avery E; Doeleman, Sheperd S; Loeb, Abraham

    2010-01-01

    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. (2009) 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 3.9-sigma level, strongly favoring length-to-width ratios of roughly 2.4:1. More importantly, we find that physically motivated accretion flow models provid...

    2012-11-01

    Full Text Available The effect of commercial heat treatment on physical and mechanical properties of compression wood (CW and opposite wood (OW of black pine (Pinus nigra Arnold was investigated. Black pine logs containing CW were cut parallel to the pith and separated into CW and OW sections. A commercial heat treatment process was applied to pine lumber at 180 and 210 ºC for 3 hours. Water absorption (WA, contact angle (CA, swelling, modulus of rupture (MOR, modulus of elasticity (MOE, and impact bending strength (IBS were measured. The results showed that heat treatment decreased water absorption and swelling of the CW and OW of black pine. Heat treatment at 210 °C temperature decreased the longitudinal swelling of CW by 51.4%. Higher immersion time lowered the effect of heat treatment on the WA values. The CA values of the CW and OW increased due to heat treatment. Heat treatment reduced the MOR, MOE, and IBS values. The results indicated that MOR, MOE, and CA values were highly affected in the CW; on the other hand, the IBS value was highly affected in the OW by heat treatment compared to control groups. The results indicate that heat-stabilized CW can be used more widely and effectively in the forest products industry.

  1. Open-ended versus guided laboratory activities: Impact on students' beliefs about experimental physics

    CERN Document Server

    Wilcox, Bethany R

    2016-01-01

    Improving students' understanding of the nature of experimental physics is often an explicit or implicit goal of undergraduate laboratory physics courses. However, lab activities in traditional lab courses are typically characterized by highly structured, guided labs that often do not require or encourage students to engage authentically in the process of experimental physics. Alternatively, open-ended laboratory activities can provide a more authentic learning environment by, for example, allowing students to exercise greater autonomy in what and how physical phenomena are investigated. Engaging in authentic practices may be a critical part of improving students' beliefs around the nature of experimental physics. Here, we investigate the impact of open-ended activities in undergraduate lab courses on students' epistemologies and expectations about the nature of experimental physics, as well as their confidence and affect, as measured by the Colorado Learning Attitudes about Science Survey for Experimental Ph...

    Full Text Available Background: Mental health problems are more commonly seen in youth, more so in medical students. Physical activity though known to improve mental health is difficult to follow among medical students. Aims & Objectives: This study aimed to investigate self-reported levels of anxiety and depression and compare these with self-reported physical activity among medical students in an institution of India. Material & Methods: A Cross sectional study was done among 430 medical students and interns of a medical college of rural Karnataka, India. Hospital Anxiety and Depression Scale (HADS and International Physical Activity Questionnaire (IPAQ were administered to assess mental health status and physical activity levels respectively. Results: The prevalence of anxiety (65.1%, depression (39.5% and anxiety with depression (34.4% was high among medical students. Only 18.1% of students were highly active while 35.9% were inactive when physical activity levels were measured. Students who were highly active and minimally active in physical activity showed lower levels of depression and anxiety compared to low physical activity group. Conclusion: Mental health problems are high and physical activity levels are low among medical undergraduate students. Engagement in physical activity can be an important contributory factor in positive mental health of future doctors.

The analyzed constructs were, as follows: behavior change strategy (15 items), decision-making process (10), self-efficacy (6), support from family (4), and support from friends (4). The validation procedures were conceptual, semantic, operational, and functional equivalences, in addition to the equivalence of the items and of measurements. The conceptual, of items and semantic equivalences were performed by a specialized committee. During measurement equivalence, the instrument was applied to 717 university students. Exploratory factor analysis was used to verify the loading of each item, explained variance and internal consistency of the constructs. Reproducibility was measured by means of intraclass correlation coefficient. RESULTS The two translations were equivalent and back-translation was similar to the original version, with few adaptations. The layout, presentation order of the constructs and items from the original version were kept in the same form as the original instrument. The sample size was adequate and was evaluated by the Kaiser-Meyer-Olkin test, with values between 0.72 and 0.91. The correlation matrix of the items presented r 0.40), varying between 0.43 and 0.80, which explained between 45.4% and 59.0% of the variance. Internal consistency was satisfactory (α ≥ 0.70), with support from friends being 0.70 and 0.92 for self-efficacy. Most items (74.3%) presented values above 0.70 for the reproducibility test.

    Brandt, W N

    2015-01-01

    We review results from cosmic X-ray surveys of active galactic nuclei (AGNs) over the past ~ 15 yr that have dramatically improved our understanding of growing supermassive black holes (SMBHs) in the distant universe. First, we discuss the utility of such surveys for AGN investigations and the capabilities of the missions making these surveys, emphasizing Chandra, XMM-Newton, and NuSTAR. Second, we briefly describe the main cosmic X-ray surveys, the essential roles of complementary multiwavelength data, and how AGNs are selected from these surveys. We then review key results from these surveys on the AGN population and its evolution ("demographics"), the physical processes operating in AGNs ("physics"), and the interactions between AGNs and their environments ("ecology"). We conclude by describing some significant unresolved questions and prospects for advancing the field.

    Full Text Available Black gram (Vigna mungo (L. Hepper variety TNAU (Bg CO 6 was exposed to varying doses of gamma rays to study their effect on various characters like seed germination and seedling survival, plant height at 30th day and at maturity, pollen and seed fertility. In M1 generation the results revealed that there was more reduction at higher doses compared to lower doses for all the characters studied. The higher doses of gamma rays lead to lethal injury and sterility. Effects on these traits have been attributed to the physiological disturbance or chromosomal damage of the cells caused by the gamma rays. The results of the present study clearly indicate that different doses of gamma rays can be effectively utilized to create variability for various quantitative traits in black gram.

  10. A note on black-hole physics, cosmic censorship, and the charge-mass relation of atomic nuclei

    Science.gov (United States)

    Hod, Shahar

    2016-02-01

    Arguing from the cosmic censorship principle, one of the fundamental cornerstones of black-hole physics, we have recently suggested the existence of a universal upper bound relating the maximal electric charge of a weakly self-gravitating system to its total mass: Z(A)≤slant {Z}*(A)\\equiv {α }-1/3{A}2/3, where Z is the number of protons in the system, A is the total baryon (mass) number, and α ={e}2/{{\\hslash }}c is the dimensionless fine-structure constant. In order to test the validity of this suggested bound, we here explore the Z(A) functional relation of atomic nuclei as deduced from the Weizsäcker semi-empirical mass formula. It is shown that all atomic nuclei, including the meta-stable maximally charged ones, conform to the suggested charge-mass upper bound. Our results support the validity of the cosmic censorship conjecture in black-hole physics.

  11. Biogeochemical and physical controls on concentrations of polycyclic aromatic hydrocarbons in water and plankton of the Mediterranean and Black Seas

    2011-12-01

    The Mediterranean and Black Seas are unique marine environments subject to important anthropogenic pressures due to atmospheric and riverine inputs of organic pollutants. They include regions of different physical and trophic characteristics, which allow the studying of the controls on pollutant occurrence and fate under different conditions in terms of particles, plankton biomass, interactions with the atmosphere, biodegradation, and their dependence on the pollutant physical chemical properties. Polycyclic Aromatic Hydrocarbons (PAHs) have been measured in samples of seawater (dissolved and particulate phases) and plankton during two east-west sampling cruises in June 2006 and May 2007. The concentrations of dissolved PAHs were higher in the south-western Black Sea and Eastern Mediterranean than in the Western Mediterranean, reflecting different pollutant loads, trophic conditions and cycling. Particle and plankton phase PAH concentrations were higher when lower concentrations of suspended particles and biomass occurred, with apparent differences due to the PAH physical chemical properties. The surface PAH particle phase concentrations decreased when the total suspended particles (TSP) increased for the higher molecular weight (MW) compounds, consistent with controls due to particle settling depletion of water column compounds and dilution. Conversely, PAH concentrations in plankton decreased at higher biomass only for the low MW PAHs, suggesting that biodegradative processes in the water column are a major driver of their occurrence in the photic zone. The results presented here are the most extensive data set available for the Mediterranean Sea and provide clear evidence of the important physical and biological controls on PAH occurrence and cycling in oceanic regions.

  13. A cognitive framework for analyzing and describing introductory students' use and understanding of mathematics in physics

    Science.gov (United States)

    Tuminaro, Jonathan

    Many introductory, algebra-based physics students perform poorly on mathematical problem solving tasks in physics. There are at least two possible, distinct reasons for this poor performance: (1) students simply lack the mathematical skills needed to solve problems in physics, or (2) students do not know how to apply the mathematical skills they have to particular problem situations in physics. While many students do lack the requisite mathematical skills, a major finding from this work is that the majority of students possess the requisite mathematical skills, yet fail to use or interpret them in the context of physics. In this thesis I propose a theoretical framework to analyze and describe students' mathematical thinking in physics. In particular, I attempt to answer two questions. What are the cognitive tools involved in formal mathematical thinking in physics? And, why do students make the kinds of mistakes they do when using mathematics in physics? According to the proposed theoretical framework there are three major theoretical constructs: mathematical resources, which are the knowledge elements that are activated in mathematical thinking and problem solving; epistemic games, which are patterns of activities that use particular kinds of knowledge to create new knowledge or solve a problem; and frames, which are structures of expectations that determine how individuals interpret situations or events. The empirical basis for this study comes from videotaped sessions of college students solving homework problems. The students are enrolled in an algebra-based introductory physics course. The videotapes were transcribed and analyzed using the aforementioned theoretical framework. Two important results from this work are: (1) the construction of a theoretical framework that offers researchers a vocabulary (ontological classification of cognitive structures) and grammar (relationship between the cognitive structures) for understanding the nature and origin of

  14. The Effects of Instruction of Creative Invention on Students' Situational Interest in Physics Lesson

    Leung, Tim

    There are a few empirical studies (Palmer, 2008; Dohn, 2010) or intervention programs (Hidi & Harackiewicz, 2000) about students' situational interest in physics lessons, although the declining interest in physics among students has been well documented in the research literature (Gardner, 1998 ; International Bureau for Education, 2001; European Commission, 2007; Oon & Subramaniam, 2011). Even in the research area of science education, yet little is known about how to trigger students' catching and holding situational interest in a physics lesson. In this study, five intervention lessons of creative invention were developed. Each lesson consists of three parts including Eberle's (1971, 1972) SCAMPER technique on the creative thinking, knowledge and concepts of physics curriculum, hands-on activities related to both SCAMPER technique and physics concepts. Two surveys were developed and used to measure the situational interest and individual interest of students in physics lessons. Qualitative conversational interviews were used to interpret the sources of situational interest of students in physics lessons. Results in this study indicate that new inventive products and television programs or films related to SCAMPER can trigger the catching interest in physics lessons. Meaningful hands-on activities related to both SCAMPER technique and physics concepts can trigger the holding interest in physics lessons. There is no significant difference in situational interest among students with different academic abilities except in the topic related to electronic components. The students with lower academic ability have greater situational interest than the students with higher academic ability in learning the topic related to electronic components. There is no significant difference in situational interest between boys and girls except in the topic related to revolving paper lantern. Girls have higher situational interest than boys in learning the topic related to revolving

    Full Text Available This study focuses on the attributes of students of physical therapy in order to compare the profiles of students of physical therapy (PT in two institutions of higher learning in Israel: Ben Gurion University (BGU and the Academic College of Judea and Samaria (ACJS. This study focuses on a department where studies have an occupational/applicative/practical orientation and high status in the higher education system. Findings of this study indicate broad similarities in the profiles of students at both institutions in relation to their age, family status, country of origin, number of siblings, parental education, and financial status of student family of origin. On the other hand, students at both institutions differed in terms of gender composition, students' employment status, the source of payment for tuition, and in their academic attainments prior to admission. Specifically, students of physical therapy at ACJS had lower academic achievements prior to their admission and reported having been rejected by other physical therapy programs. Students at ACJS placed higher importance on factors relating to the quality of instruction including teacher involvement, competitiveness, organization, control, and orientation to the study material. Students at BGU attributed greater importance to teachers' support. Findings support a thesis of a converging system of higher education in Israel, traditionally dominated by national universities and regional colleges, a relatively recent phenomenon.

    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

    The Society of Physics Students chapter at Indiana Wesleyan University is unusual in that it has no physics major, only physics minors. Yet while just over a year old, IWU-SPS has been active in performing physics outreach to middle school and high school students, and the rural community of Grant County. Our year-old SPS chapter consists of majors from Chemistry, Nursing, Biology, Exercise Science, Computer Science, Psychology, Pastoral Studies, and Science Education, who share a common interest in physics and service to the community. IWU currently has a physics minor and is currently working to build a physics major program. Despite the intrinsic challenges, our multi-disciplinary group has been successful at using physics demonstration equipment and hands-on activities and their universal appeal to raise the interest in physics in Grant County. We report our experience, challenges, and successes with physics outreach. We describe in detail our two-pronged approach: raising the level of physics appreciation among the IWU student community and among pre-college students in a rural community of Indiana.

    The geospace environment is controlled largely by events on the Sun, such as solar flares and coronal mass ejections, which generate significant geomagnetic and upper atmospheric disturbances. The study of this Sun-Earth system, which has become known as space weather, has both intrinsic scientific interest and practical applications. Adverse conditions in space can damage satellites and disrupt communications, navigation, and electric power grids, as well as endanger astronauts. The Center for Integrated Space Weather Modeling (CISM), a Science and Technology Center (STC) funded by the U.S. National Science Foundation (see http://www.bu.edu/cism/), is developing a suite of integrated physics-based computer models that describe the space environment from the Sun to the Earth for use in both research and operations [Hughes and Hudson, 2004, p. 1241]. To further this mission, advanced education and training programs sponsored by CISM encourage students to view space weather as a system that encompasses the Sun, the solar wind, the magnetosphere, and the ionosphere/thermosphere. This holds especially true for participants in the CISM space weather summer school [Simpson, 2004].

    Langton, Stewart Gordon

    Two groups of students in introductory physics courses of an Access Program for engineering technologies were the subjects of this study. Students with a wide range of academic histories and abilities were enrolled in the program; many of the students were re-entry and academically unprepared for post-secondary education. Five years of historical data were evaluated to use as a benchmark for revised instruction. Data were gathered to describe the pre-course academic state of the students and their academic progress during two physics courses. Additional information was used to search for factors that might constrain academic success and as feedback for the instructional methods. The data were interpreted to regulate constructivist design features for the physics courses. The Engineering Technology Access Program was introduced to meet the demand from non-traditional students for admission to two-year engineering' technology programs, but who did not meet normal academic requirements. The duration of the Access Program was two terms for electronic and computer engineering students and three terms for civil and mechanical engineering students. The sequence of mathematics and physics courses was different for the two groups. The Civil/Mechanical students enrolled in their first mathematics course before undertaking their first physics course. The first mathematics and physics courses for the Electronics students were concurrent. Academic success in the two groups was affected by this difference. Over a five-year period the success rate of students graduating with a technology diploma was approximately twenty-five percent. Results from this study indicate that it was possible to reduce the very high attrition in the combined Access/Technology Programs. While the success rate for the Electronics students increased to 38% the rate for the Civil/Mechanical students increased dramatically to 77%. It is likely that several factors, related to the extra term in the Access

    Full Text Available The questions of motivation of students to educational activity are examined. 164 students of 1-4 courses of faculty of physical education took part in research. Limiting factors, impedimental forming of positive motivation of students to teaching, are exposed (weak personal interest by the executable types of works; weak demand to itself; absence of self-control; low level of ambition. It is set that motivational situations of students in a greater degree as negative are estimated. These motivational situations testify to the low personal interest in executable work and about effective stimuli. It is developed organizationally-pedagogical terms of process of teaching and physical education of students.

  18. Unraveling Gender Bias from Student Evaluations of their High School Physics Teachers

    Science.gov (United States)

    Hazari, Zahra; Potvin, Geoff; Tai, Robert; Sadler, Philip

    2009-05-01

    In this talk, the evaluation of high school physics, chemistry, and biology teachers by their students is examined according to the gender of the student and the gender of the teacher. Female teachers are rated significantly lower than male teachers by male students in all three disciplines, while female students under-rate female teachers only in physics. Interestingly, physics is also the field that suffers the greatest lack of females and has been criticized most for its androcentric culture. The gender bias in teacher ratings persists even after accounting for academic performance, classroom experiences, and family support. Further, male and female teachers in each discipline appear equally effective at preparing their students for future science study in college, suggesting that students have a discipline-specific gender bias. Such a bias may negatively impact female students and contribute to the loss of females in STEM fields.

    Full Text Available The purpose of this study was to examine the benefits of physical exercise among secondary school students. Participants in the study were 251 students (120 boys and 131 girls attending three public secondary schools in the Hlanganani rural area of South Africa. A validated questionnaire was used to collect data. Results of this study indicated that students exercised to be with their friends, to be physically attractive and compete with others. The findings of this study have practical implications for promoting participation in physical activity among students in rural schools. In an effort to promote physical activity participation, schools should be provided with quality sports infrastructure and funding so that they can implement school sport programmes. Finally, the teaching of physical education should be emphasised in schools as it is the cornerstone for children’s involvement in physical activity.

  20. Knowledge construction in high school physics: A study of student/teacher interaction

    Science.gov (United States)

    Wessel, Warren Edward

    This study is a description and analysis of student learning when required to use vector mathematics to represent two dimensional situations in the solution of grade 12 physics problems. Coupled with this exploration, the role of a teacher as a facilitator in creating effective conditions and interactions to facilitate student knowledge construction was critically analyzed. Nine grade 12 physics students volunteered to participate in a process of articulating their reasoning and problem solving strategies over a sixteen week period in a regular secondary school classroom setting. The participants were taught the normal content of the Saskatchewan grade 12 physics curriculum by the researcher who is an accredited, experienced physics teacher. Data were collected by video recording of classroom sessions, interviews, student assignments, and field notes maintained by the researcher. Student learning is described through a combination of excerpts of student discourse and data collected from other sources during the study. Interpretation of student-teacher interaction is informed by a constructivist perspective of student knowledge construction and conceptual development in science education, and the personal teaching experience of the researcher. Student learning during increasingly complex use of vector mathematics is described. The sequence of topics begins with vector addition and subtraction, and problems requiring those functions for solution. Vector components are then developed using a combination of classroom activities and interactive discussion. The final topic developed is momentum. Students were found to have well developed experiential knowledge which interfered with their construction of conceptual knowledge. Concrete examples did not guarantee that students would develop conceptual understanding of a given phenomenon. Students used algorithms indiscriminately and often did not know if their answers were reasonable. When momentum was introduced, the
