  7. Science fair: Is it worth the work? A qualitative study on deaf students' perceptions and experiences regarding science fair in primary and secondary school

    NASA Astrophysics Data System (ADS)

    Smith, Vivian Lee

    Science fairs have a long history in American education. They play an important role for establishing inquiry-based experiences in a science classroom. Students may be more motivated to learn science content when they are allowed to choose their own science fair topics. The purpose of this study was to examine Deaf college students' perceptions and experiences regarding science fair participation during primary and/or secondary school and determine the influence of science fair involvement on the development of language skills, writing skills, and higher order thinking skills as well as its impact on choice of a STEM major. This study examined responses from Deaf students attending Gallaudet University and National Technical Institute for the Deaf (NTID) majoring in a Science, Technology, Engineering, or Math (STEM) field. An electronic questionnaire and a semi-structured interview were used to collect data. The electronic questionnaire was divided into two strands: demographics and science fair experience. Twenty-one respondents participated in the questionnaire and ten participants were interviewed. A cross-case analysis revealed communication was the key to a successful science fair experience. Findings showed the educational background of participants influenced their perspective regarding the experience of a science fair. When communicating through American Sign Language, the science fair experience was more positive. When communicating through an interpreter or having no interpreter at all, the science fair experience was viewed in a negative light. The use of science fairs to enhance language development, writing skills, and higher order thinking skills was supported. Teachers and parents were strong influences for Deaf students participating in a science fair. Participation in a science fair did influence students to choose a STEM major but there were other considerations as well.

Six research questions guided the study: (1) What knowledge, skills and attitudes do the five selected elementary school teachers draw upon to enable their students to have a successful science fair experience? (2) How do the five selected elementary school teachers enable their students to have a successful science fair experience? (3) Why are the five selected elementary school teachers capable of enabling their students to have a successful science fair experience? (4) How do the knowledge, skills and attitudes of the five selected elementary school teachers compare to the knowledge, skills and attitudes that the National Science Education Standards (National Research Council, 1996) recommend for science teachers? (5) What are the commonalities in the knowledge, skills and attitudes among the five selected elementary school teachers who enable their students to have a successful science fair experience? (6) What are the differences in the knowledge, skills and attitudes among the five selected elementary school teachers who enable their students to have a successful science fair experience? A qualitative multiple-case research design was used to focus on five elementary school teachers who have a history of leading their students to successful experiences in science fairs. Data sources included classroom observations, formal and informal interviews, focus groups, science fair visitations and perusal of documents related to the teachers' science fair preparation of their students. In addition, questionnaires were given to the teachers and their students assessing their views about science and science fairs. A cross-case analysis revealed that the teachers had become knowledgeable about science fairs and science by non-traditional means including attending staff development workshops

  17. Science Fairs for Science Literacy

    NASA Astrophysics Data System (ADS)

    Mackey, K. R.

    2014-12-01

    Science literacy is imperative for well informed civic and personal decision making, yet only a quarter of American adults are proficient enough in science to understand science stories reported in the popular press. Hands-on research increases confidence in and understanding of science. When guiding students in designing and conducting science fair projects, mentors can foster science literacy by helping students focus on three goals: (1) articulating hypotheses or questions, (2) designing feasible projects, and (3) learning to make and interpret graphs. These objectives introduce students to the methodological nature of scientific research and give them the tools to interpret scientific facts and data in order to make informed decisions for themselves and society.

    2004-12-01

    ``Extrasolar Planet Transit", ``Lightcurve of a Variable Star", and ``Retrograde Motion of Mars" are some of the titles of high school students' projects entered in the Hawaii State Science Fair. TOPS (Toward Other Planetary Systems) teachers who participated in the University of Hawaii Institute for Astronomy summer outreach program under the direction of professor Karen J. Meech mentored their students. After attending the 3-week National Science Foundation Institute for several summers since 1999, these teachers in the summer of 2003 were trained to do observing plans to obtain images from telescopes, use image processing software MIRA for photometry, and produce light curves of variable stars and extrasolar planet transits. Others used the software ``Astrometrica" to do astrometry of Kuiper Belt Objects. Using Compaq laptop computers on long term loan, our teachers mentored students for astronomy projects during the 2003-2004 school year. These students made observing plans for images from the 31inch Lowell Telescope in Arizona and/or from the 2.2m University of Hawaii Telescope at Mauna Kea Observatory. Learning about filters, exposure time, magnitude, frequency of taking CCD images, and ephemeris required many iterations between students, teachers, and astronomers and graduate students who were assisting. Poor weather conditions and other frustrations exposed the students to the realities of research. However, they were rewarded with projects that impressed the judges and that will be described.

These students were mentored by teachers who participated in the UH Institute for Astronomy Toward Other Planetary Systems summer program under the direction of professor Karen J. Meech. After attending several 3-week TOPS NSF workshops from 1999, these teachers in 2003 were trained to do observing plans to obtain telescope images, use image processing software MIRA for photometry, and produce light curves of variable stars and extrasolar planet transits. Others used the software Astrometrica to do astrometry of Kuiper Belt Objects. Using Compaq laptop computers on long term loan, our teachers mentored their students for astronomy projects during the 2003-2004 school year with the assistance of IfA astronomers and graduate students. Observing plans for images from the 31 inch Lowell Telescope in Arizona and the 2.2 meter UH telescope at Mauna Kea Observatory were followed. Students had to learn about variables such as exposure time, magnitude, frequency requirements, and ephemeris. The many iterations were time consuming and demanded patience and perseverance. Poor weather conditions exposed the students to the realities of astronomy research, so they experienced the highs of successful projects. Future projects will be related to the UH NAI team research using the 2.0 meter Faulkes Telescope located on Haleakala on island of Maui. The TOPS program is funded by National Science Foundation.

  18. BOOK REVIEW: Science Fair Projects: Physics

    NASA Astrophysics Data System (ADS)

    Reynolds, Helen

    2000-11-01

    I have often thought that the notion of a Science Fair is intrinsically a good one but have never set one up. With this book such an undertaking is possible, with 47 projects from which you can choose. Each project has a clearly stated purpose with an overview that contains the physics you need to get started. A hypothesis, or sometimes two, and a procedure detailing what the student should do follow this. The materials to be used are those you should be able to find at home, and safety guidelines as well as places the student needs adult help are clearly marked. Every project asks the student to write down the results of their experiment and decide whether or not their hypothesis was correct. There are also suggestions for taking each project further. Some of these projects are standard experiments that you may already do with students in class, for example, making plasticine boats, string telephones and levers. Most are interesting twists on standard experiments such as using a wedge as a simple machine, home-made spinning toys and the experiments with light bulbs. The latter are the only real cause for concern if students were to do these things at home as adult supervision would be essential. This is obviously an American book, though. Teachers in British classrooms would need to work out how to deal with the references to temperature in Fahrenheit and mass in ounces. Length is usually given in centimetres as well as inches. Translations of soda bottles and bobby pins would also be needed. This book is designed to be full of ideas and to give structure to projects students can do at home, not to provide ideas that you can transport into the classroom. It does this very well and I would recommend it to anyone thinking of starting up a Science Fair. Alternatively, this is an excellent resource for more interesting homework assignments that would put more responsibility on the student and give them something fun to do.

    "I have a confession to make," U.S. president Barack Obama told the audience of young inventors and their mentors at a 27 May White House Science Fair ceremony in the East Room of the White House. "When I was growing up, my science fair projects were not as successful as the ones here." Recalling that during one of his experiments, "a bunch of mice escaped in my grandmother's apartment," Obama joked, "These experiments did not take me straight to the White House."

    Science fairs are a popular way for junior and senior high school students (grades 7 through 12) to display science and engineering projects and participate in a competition for prizes and honors. In the state of Ohio students can advance through their school fairs to district science fairs and then on to the State Science Day in early May. The University of Cincinnati (UC) has hosted one of the Ohio district science fairs since 2005 - the official name is the UC Science and Engineering Expo (UCSEE). The University hosts between 300 and 400 student projects at this event. The day itself includes the training of the 200+ judges, the actual judging, activities for the students' families and friends, tours of the UC campus facilities, and culminates with a guest speaker and an awards ceremony. The students compete for prizes and scholarships worth approximately 50k and over 100 of the UCSEE projects typically advance to participate in State Science Day. Additionally some top projects from the UCSEE are also sent directly to the International Science and Engineering Fair (ISEF). The authors have been heavily involved in the planning, organization and production of the UCSEE since UC began offering it in 2005. Much of the planning and background work, as well as memories, from this major project will be discussed in this presentation.

    The proposed project FAIR (Facility for Anti-proton and Ion Research) is an international accelerator facility of the next generation. It builds on top of the experience and technological developments already made at the existing GSI facility, and incorporate new technological concepts. The four scientific pillars of FAIR are NUSTAR (nuclear structure and astrophysics), PANDA (QCD studies with cooled beams of anti-protons), CBM (physics of hadronic matter at highest baryon densities), and APPA (atomic physics, plasma physics, and applications). The FairRoot framework used by all of the big FAIR experiments as a base for their own specific developments, provides basic functionality like IO, geometry handling etc. The challenge is to support all the different experiments with their heterogeneous requirements. Due to the limited manpower, one of the first design decisions was to (re)use as much as possible already available and tested software and to focus on the development of the framework. Beside the framework itself, the FairRoot core team also provides some software development tools. We will describe the complete set of tools in this article. The Makefiles for all projects are generated using CMake. For software testing and the corresponding quality assurance, we use CTest to generate the results and CDash as web front end. The tools are completed by subversion as source code repository and trac as tool for the complete source code management. This set of tools allows us to offer the full functionality we have for FairRoot also to the experiments based on FairRoot.

  9. Can participation in a school science fair improve middle school students' attitudes toward science and interest in science careers?

    NASA Astrophysics Data System (ADS)

    Finnerty, Valerie

    The purpose of this study was to investigate whether participation in a school-based science fair affects middle school students' attitudes toward science and interest in science and engineering careers. A quasi-experimental design was used to compare students' pre- and posttest attitudes toward and interest in science. Forty-eight of the 258 participants completed a school-based science fair during the study. In addition, twelve middle school science teachers completed an online survey. Both the Survey of Science Attitudes and Interest I and II (SSAI-I and II) measured students' attitudes toward and interest in science and science and mathematics self-efficacy, asked about classroom inquiry experiences and gathered demographic information. An online survey gathered qualitative data about science teachers' perceptions of school science fairs. The results showed no significant interactions among completion of a science fair project and attitudes toward and interest in science, science and mathematics self-efficacy or gender. There were significant differences at both pre- and posttest in attitudes between the students who did and did not complete a science fair project. All participating teachers believed that participation in science fairs could have a positive effect on students' attitudes and interest, but cited lack of time as a major impediment. There was significant interaction between level of classroom inquiry and attitudes and interest in science; students who reported more experiences had higher scores on these measures. Classroom inquiry also interacted with the effects of a science fair and participants' pre- and posttest attitude scores. Finally, the amount and source of assistance on a science fair project had a significant impact on students' posttest measures. Major limitations which affect the generalization of these findings include the timing of the administration of the pretest, the number of participants in the experimental group and differences

    Electroanalytical chemistry has been a primary activity in Ph.D.-granting institutions since the 1940s. It has proved to be an excellent tool for research, enabling students to think in time and space and grasp thermodynamics, kinetics, and instrumentation principles as applied to accessible measurements. This personal perspective is an informal review of this dynamic field from the late 1950s to the present. During this period, the capability of instrumentation advanced by six orders of magnitude in many respects. The author began his career in 1960 with a high school science fair project on electrochemistry. This evolved into undergraduate, doctoral, and postdoctoral research, leading to a career in academia and industry.

    With student participants in the second annual White House Science Fair as a backdrop, President Barack Obama announced on 7 February programs to help prepare new math and science teachers and to meet a new goal of having 1 million more U.S. college graduates in science, technology, engineering, and math (STEM) over the next decade than there would be at the current graduation rate. That goal is outlined in a report entitled “Engage to excel,” by the President's Council of Advisors on Science and Technology (PCAST), released the same day. Obama also announced several other initiatives, including a $22 million private-sector investment, led by the Carnegie Corporation of New York, to invest in STEM teacher training. After he toured the science fair projects, Obama said the science fair students “inspire” him. “What impresses me so much is not just how smart you are, but it's the fact that you recognize you've got a responsibility to use your talents in service of something bigger than yourselves,” he said. What these young people are doing is “going to make a bigger difference in the life of our country over the long term than just about anything,” adding, “We've got to emphasize how important this is and recognize these incredible young people who are doing that that I couldn't even imagine thinking about at fifth grade or eighth grade or in high school.”

  7. From science fair to project-based science: A study of the implementation of an innovation through an existing activity system

    NASA Astrophysics Data System (ADS)

    Walker, Lisa Jean

    The implementation process is critical to the success of educational innovations. Project-based science is an innovation designed to support students' science learning. Science fair is a pervasive school practice in which students exhibit science projects. Little is known about how science fair may affect the implementation of reform efforts in science education. This study explores the relationship of science fair and project-based science in the classrooms of three science teachers. Two theories are used to understand science fair as an instructional practice. Cultural historical activity theory supports an analysis of the origins and development of science fair. The idea of communities of practice supports a focus on why and how educational practitioners participate in science fair and what meanings the activity holds for them. The study identifies five historically-based design themes that have shaped science fair: general science, project method, scientific method, extra-curricular activity, and laboratory science. The themes provide a new framework for describing teachers' classroom practices for science fair activities and support analysis of the ways their practices incorporate aspects of project-based science. Three case studies in Chicago present ethnographic descriptions of science fair practices within the context of school communities. One focuses on the scientific method as a linear process for doing science, another on knowledge generation through laboratory experiments, and the third on student ability to engage in open-ended inquiry. One teacher reinvents a project-based science curriculum to strengthen students' laboratory-based science fair projects, while another reinvents science fair to teach science as inquiry. In each case, science fair is part of the school's efforts to improve science instruction. The cases suggest that reform efforts help to perpetuate science fair practice. To support systemic improvements in science education, this

  8. The Compressed Baryonic Matter Experiment at FAIR

    NASA Astrophysics Data System (ADS)

    Senger, Peter

    Substantial experimental and theoretical efforts worldwide are devoted to explore the phase diagram of strongly interacting matter. At top RHIC and LHC energies, the QCD phase diagram is studied at very high temperatures and very low net-baryon densities. These conditions presumably existed in the early universe about a microsecond after the big bang. For larger net-baryon densities and lower temperatures, it is expected that the QCD phase diagram exhibits a rich structure such as a critical point, a first order phase transition between hadronic and partonic matter, or new phases like quarkyonic matter. The experimental discovery of these prominent landmarks of the QCD phase diagram would be a major breakthrough in our understanding of the properties of nuclear matter. The Compressed Baryonic Matter (CBM) experiment will be one of the major scientific pillars of the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt. The goal of the CBM research program is to explore the QCD phase diagram in the region of high baryon densities using high-energy nucleus-nucleus collisions. This includes the study of the equation-of-state of nuclear matter at neutron star core densities, and the search for the deconfinement and chiral phase transitions. The CBM detector is designed to measure rare diagnostic probes such as multi-strange hyperons, charmed particles and vector mesons decaying into lepton pairs with unprecedented precision and statistics. Most of these particles will be studied for the first time in the FAIR energy range. In order to achieve the required precision, the measurements will be performed at very high reaction rates of 100 kHz to 10 MHz. This requires very fast and radiation-hard detectors, and a novel data read-out and analysis concept based on free streaming front-end electronics and a high-performance computing cluster for online event selection.

  11. Evaluation of constructivist pedagogy: Influence on critical thinking skills, science fair participation and level of performance

    NASA Astrophysics Data System (ADS)

    Foxx, Robbie Evelyn

    Science education reform, driven by a rapidly advancing technological society, demands the attention of both elementary and middle school curriculum-developers. Science education training in current standards (National Research Council [NRC] Standards 1996) emphasize inquiry, which is reported to be a basic tenet of the theory known as constructivism (NAASP, 1996; Cohen, 1988; Conley, 1993; Friedman, 1999; Newman, Marks, & Gamoran, 1996; Smerdon & Burkam 1999; Sizer 1992; Talbert & McLaughlin 1993; Tobin & Gallagher, 1987; Yager, 1991, 2000). Pedagogy focusing on the tenets of constructivist theory, at the intermediate level, can address current science standards. Many science educators believe participation in science fairs helps students develop the attitudes, skills, and knowledge that will help them to be comfortable and successful in the scientific and technological society (Czerniak, 1996). Competing in science fairs is one vehicle which allows students to apply science to societal issues, solve problems and model those things scientists do. Moreover, constructing a science fair project is suggested as being an excellent means to foster the development of concepts necessary in promoting scientific literacy (Czerniak, 1996). Research further suggests that through science fairs or other inquiry activities, students construct their knowledge with fewer misconceptions as they explore and discover the nature of science (NRC 1996). Tohn 's study (as cited in Bellipanni, 1994) stated that science fairs are a major campaign to increase student skills and to allow students a chance to have fun with science. The purpose of this research was twofold: (1) to assess science problem solving skills of students instructed using constructivist pedagogy, and (2) to explore the effects of constructivist pedagogy's influence(s) on science fair participation/placement. Students' attitudes resulting from these experiences were examined as well.

    In 2005, Swiss citizens endorsed a moratorium on gene technology, resulting in the prohibition of the commercial cultivation of genetically modified crops and the growth of genetically modified animals until 2013. However, scientific research was not affected by this moratorium, and in 2008, GMO field experiments were conducted that allowed us to examine the factors that influence their acceptance by the public. In this study, trust and confidence items were analyzed using principal component analysis. The analysis revealed the following three factors: "economy/health and environment" (value similarity based trust), "trust and honesty of industry and scientists" (value similarity based trust), and "competence" (confidence). The results of a regression analysis showed that all the three factors significantly influenced the acceptance of GM field experiments. Furthermore, risk communication scholars have suggested that fairness also plays an important role in the acceptance of environmental hazards. We, therefore, included measures for outcome fairness and procedural fairness in our model. However, the impact of fairness may be moderated by moral conviction. That is, fairness may be significant for people for whom GMO is not an important issue, but not for people for whom GMO is an important issue. The regression analysis showed that, in addition to the trust and confidence factors, moral conviction, outcome fairness, and procedural fairness were significant predictors. The results suggest that the influence of procedural fairness is even stronger for persons having high moral convictions compared with persons having low moral convictions. PMID:22150405

    2006-12-01

    For this outreach project we created watershed scale field activities in the Mendenhall Glacier system in Juneau, Alaska to introduce pre-college students to earth surface processes. These activities were designed to teach field data collection methods and to provide experiences that included exposure to the disciplines of glaciology, hydrology, and geomorphology. Students used their own observations to understand the on-going effects of warming climate in southeastern Alaska. Twenty seven, pre-college students from throughout the state participated in a 5-day, two-credit, introductory college-level course. This course was designed to introduce them to earth science as practiced in the field. Students divided their time between field sessions with data collection and indoor GIS labs. EDGE field excursions enabled students to learn about glacial geomorphology from river rafts, to collect stream discharge and other hydrologic data in local streams, and to integrate glacier recession observations with GPS waypoints collected from observed recessional positions. In labs at the University of Alaska Southeast campus, EDGE students were introduced to the fundamentals of ArcGIS. They downloaded their GPS waypoints onto modern and historic maps. They analyzed their stream flow data and created dynamic maps using their own observations in the field. During Fall 2006 semester, the students will generate earth science projects in their villages and towns that they can complete and present to their peers. EDGE teachers who attended a 10 day workshop in June will mentor their EDGE students. EDGE teachers and students will return to the UAS Juneau campus in March 2007 for a symposium. EGDE students will present their projects to Juneau area undergraduates and Juneau School District K-12 classes. In addition EDGE high school students will have the option to enter and compete in the Southeast Alaska Regional Science Fair held the same weekend. Funding from the National Science

    Standardized measurement instruments (tests) have become an essential tool in health sciences. The concept of equity in the development, adaptation and administration of psychometric tests was first introduced in "Standards for Educational and Psychological Testing" published in 1999 by the American Educational Research Association, the American Psychological Association, and the National Council on Measurement in Education. Despite its importance, this concept has been scarcely used in epidemiology and public health. Consequently, this methodological note aims to explain the concept of equity in testing and to provide tools and indications to detect and solve their inequitable use. PMID:24928357

    The purpose of this 3 year project funded by NSF (GEO 1035049) is to increase the climate change science content knowledge and teaching effectiveness of in-service high school science teachers and increase the numbers of quality of high school geoscience projects competing in Nevada's three regional Intel ISEF (International Science & Engineering Fair) affiliated science fairs. In year 1 of the project participants consisted of six female and three male high school teachers from across Nevada. Eight of the participants were white and one was Asian. Five participants taught in Clark County, two taught in Owyhee, one taught in Elko and one taught in Spring Creek. Over 20% of the projects were noted (by the teachers) as being submitted by underrepresented students; however, this information is not reliable as most students did not provide this data themselves. Pre-and post- content tests were given. Teachers improved from an average of eight missed on the pre-test to an average of only four items missed on the post-test. Participants were also asked to evaluate their own teaching efficacy. In general, participants had a strong science efficacy. The item on which there was the most discrepancy among participants was on #10, the one stating that "The low achievement of some students cannot generally be blamed on their teachers." Most teachers completed an end of year program evaluation. All but one of the participants felt that the pace of the workshop was comfortable. All participants who used faculty mentors in helping their students rated their faculty mentors very highly. All participants rated the program content very highly in terms of clarity, organization, relevance, helpfulness and usefulness. All participants gave the program a very high rating overall and stated they would likely use the information to mentor future students and in instruction in future classes. The science fairs are the culmination of the program. Teachers were required to have at least one

    With the East Room of the White House flush with Nobel laureates and government officials, including freshly sworn-in U.S. National Science Foundation director Subra Suresh, President Barack Obama honored dozens of students who participated in a White House science fair on 18 October. The fair—many of whose participants have won other science, technology, engineering, and math (STEM) competitions—is part of a series of events that culminated 23-24 October in the USA Science and Engineering Festival on the National Mall in Washington, D. C., and at 50 satellite events around the country. “We welcome championship sports teams to the White House to celebrate their victories,” Obama said, noting that the Los Angeles Lakers basketball team, New Orleans Saints football team, and others have been to the White House. “I thought we ought to do the same thing for the winners of science fair and robotic contests and math competitions, because often we don’t give these victories the attention that they deserve. When you win first place at a science fair, nobody is rushing the field or dumping Gatorade over your head [in celebration].”

  5. Development of an instrument to measure student attitudes toward science fairs

    NASA Astrophysics Data System (ADS)

    Huddleston, Claudia A.

    Science fairs are woven into the very fabric of science instruction in the United States and in other countries. Even though thousands of students participate in science fairs every year, no instrument to measure student attitudes toward partaking in this hands-on learning experience has been fully developed and available for school administrators and teachers to assess the perceived value that current students attribute to participation in science fairs. Therefore, the purpose of this study was to continue the development and refinement of an instrument that measured student attitudes towards science fairs based on an unpublished instrument created by Michael (2005). The instrument developed and tested using 110 students at two different middle schools in southwest Virginia. The instrument consisted of 45 questions. After applying a principal component factor analysis, the instrument was reduced to two domains, enjoyment and value. The internal consistency of the instrument was calculated using Cronbach's alpha and showed good internal consistency of .89 between the two domains. Further analysis was conducted using a Pearson product-moment test and showed a significant positive correlation between enjoyment and value (r = .78). Demographic information was explored concerning the domains using a series of statistical tests, and results revealed no significant differences among race and science fair category. However, a significant difference was found among gender and students who won awards and those who did not. The conclusion was that further development and refinement of the instrument should be conducted.

  6. The use of animals in national high school student science fair projects in the United States.

    Miller-Spiegel, Crystal

    2004-06-01

    Science fair projects can provide a sound opportunity to teach students the value of scientific methodology without relying on the routine and unnecessary use of animals. Unfortunately, students are often encouraged to use animals in an expendable manner that both duplicates previous experiments and neglects the opportunity to "think outside the box" in order to generate new hypotheses/theories about human health, physiological processes or basic biological concepts. Although at least one national science fair sponsor has changed its policy regarding students' utilisation of vertebrate animals, others continue to encourage the more traditional in vivo experimental projects. This paper will review the guidelines of two major national science fairs in the USA; types of projects conducted that involve animals; numbers of animals involved; interview responses by some student finalists who used vertebrates in their projects; successful initiatives by animal advocates in the USA to eliminate the use of animals in science fairs; and potential areas of outreach to science educators, science fair sponsors, high schools and students.

    2000-05-01

    High school science fair competition is an underutilized yet highly beneficial experience for students. It requires creativity, practicing the scientific method, conducting and determining appropriate math manipulations, and organizational and writing skills. Because of the time commitment and resources needed for science fair participation, it is often not selected as an activity for high school students. However, the potential exists to increase the number of high school students who participate in science fairs by developing a collegial relationship between university faculty and high school teachers. For the past several years, a local high school chemistry teacher has brought an honors chemistry class to our campus to discuss science fair projects with faculty. This allowed a valuable dialogue where ideas for projects were discussed and meeting times set to use equipment not available at the high school. Past projects have been continued in subsequent years by new students to improve the quality of initial projects and decrease the number of new ideas needed each year. An established collaboration with a local resource, whether it is a university or trained professionals from local industry, can enhance the enthusiasm, resources, and experimental design of science fair projects and thus the scientific thought process of high school students.

    For the past five years, the Coalition for Plasma Science (CPS) has presented an award for a plasma project at the Intel International Science and Engineering Fair (ISEF). Eligible projects have ranged from grape-based plasma production in a microwave oven to observation of the effects of viscosity in a fluid model of quark-gluon plasma. Most projects have been aimed at applications, including fusion, thrusters, lighting, materials processing, and GPS improvements. However diagnostics (spectroscopy), technology (magnets), and theory (quark-gluon plasmas) have also been represented. All of the CPS award-winning projects so far have been based on experiments, with two awards going to women students and three to men. Since the award was initiated, both the number and quality of plasma projects has increased. The CPS expects this trend to continue, and looks forward to continuing its work with students who are excited about the possibilities of plasma. You too can share this excitement by judging at the 2010 fair in San Jose on May 11-12.

    Davidson, Rosemary McBryan

    This teacher research study documents the processes used to help students in an all-female, religious-based high school create science fair projects that are personally meaningful, scientifically sophisticated and up-to date in terms of science content. One-hundred sixteen young women in an honors chemistry class were introduced by their teacher to the methods used by science journalists when researching and crafting articles. The students then integrated these strategies into their science fair research through collaborative classroom activities designed by their teacher. Data collected during the process included audio and video tapes of classroom activities, student interviews, process work, finished projects, email conversations and the reflective journaling, annotated lesson plans, and memories of the lived experience by the teacher. The pedagogical changes which resulted from this project included the use of Read Aloud-Think Alouds (RATA) to introduce content and provide relevance, a discussion based topic selection process, the encouragement of relevant topic choices, the increased use of technology for learning activities and for sharing research, and an experimental design process driven by the student's personally relevant, topic choice. Built in feedback loops, provided by the teacher, peer editors and an outside editor, resulted in multiple revisions and expanded opportunities for communicating results to the community-at-large. Greater student engagement in science fair projects was evident: questioning for understanding, active involvement in decision making, collaboration within the classroom community, experience and expertise with reading, writing and the use of technology, sense of agency and interest in science related activities and careers all increased. Students communicated their evolving practices within the school community and became leaders who promoted the increased use of technology in all of their classes. Integrating journalistic

    1991-01-01

    The need for more students to enter the field of science is acute in the nation, and science fair projects provide a motivational mechanism to entice students into pursuing scientific careers. Computers play a major role in science today. Because computers are a major source of entertainment for our children, one would expect them to play a significant role in many science fair projects. This study investigated current and potential uses of computers in science fair projects and incorporated an informal case study of scientists, teachers, and students involved in science fair projects from a highly scientific community. Interviews, a survey, and observations were conducted. Results indicated that most projects either do not use or inadequately use computers and that a significant potential for more effective use of computers for science fair projects exists.

  12. Science fairs and Science Olympiad: Influence on student science inquiry learning and attitudes toward STEM careers and coursework

    NASA Astrophysics Data System (ADS)

    Schmidt, Kathleen M.

    Thousands of middle school students participate in science competitions such as science fairs and Science Olympiad yearly, but little is known about the effects of their participation on their attitudes toward science, technology, engineering and mathematics (STEM) coursework and careers. Even less is known about whether they increase students' understanding of the practices of scientific inquiry. In this study, 86 seventh-grade students from eight schools who participated in either science fair or Science Olympiad competitions were assessed regarding their attitudes toward STEM coursework and careers and the extent of their science inquiry skills. Quantitative data were collected through pre- and post- competition written assessments. Qualitative data were collected through post-competition focus groups. Both groups increased their understanding of science inquiry as a result of their participation in science competitions. Student attitudes toward STEM coursework and careers were generally positively influenced by their participation in science competitions. However, there was a subgroup of science fair participants for which the opposite was true. The strengths of Science Olympiad programs were the opportunities to study science topics on a deep level, to work with teammates, and to compete. However, there was little student choice at the schools studied because the coaches chose the teams and generally assigned students to particular Science Olympiad events. The level of science inquiry varied according to event. Strengths of the science fair programs were student choice regarding topics and a focus on science inquiry. However, the level of stress experienced by some students, and the negative attitudes toward science that resulted, called into question the appropriateness of engaging in a project of the length and complexity of a typical science fair project with this age group. Recommendations for Science Olympiad competitions are adding events that allow more

  13. A descriptive study of the middle school science teacher behavior for required student participation in science fair competitions

    NASA Astrophysics Data System (ADS)

    Fisanick, Laura M.

    This descriptive study explores three aspects of teacher behavior related to student participation in science fair competitions: teacher attitudes, teacher preference for different student-learning modes, and teacher motives for required student participation. Teacher motives for required student participation may stem from curriculum and standardized test requirements, school administrators' expectations, teacher preference for a competitive student-learning mode, and teacher attitudes towards science fair competitions. Survey data collected for this study included teacher attitudes about science fair competitions, teacher preference for different student-learning modes, and demographic data about middle school teachers who sponsor students in PJAS science fair competitions. The theoretical framework in this study is the theory of planned behavior proposed by Ajzen. The results from the analysis of data in this study showed that the majority of the teachers in this sample held positive attitudes towards science fair competitions and required their students to conduct science fair projects but did not require their students to participate in science fair competitions. The middle school science teachers in the sample would involve their students in PJAS competitions even if their districts did not require them to participate. The teachers in this study preferred the cooperative and individualistic student-learning modes. Teacher gender did not influence a preference for a particular student-learning mode. Using the theoretical framework from this study revealed teachers who required their students to participate in science fair competitions also required their students to conduct science fair projects.

  14. Making science education meaningful for American Indian students: The effect of science fair participation

    Welsh, Cynthia Ann

    Creating opportunities for all learners has not been common practice in the United States, especially when the history of Native American educational practice is examined (Bull, 2006; Chenoweth, 1999; Starnes, 2006a). The American Indian Science and Engineering Society (AISES) is an organization working to increase educational opportunity for American Indian students in science, engineering, and technology related fields (AISES, 2005). AISES provides pre-college support in science by promoting student science fair participation. The purpose of this qualitative research is to describe how American Indian student participation in science fairs and the relationship formed with their teacher affects academic achievement and the likelihood of continued education beyond high school. Two former American Indian students mentored by the principal investigator participated in this study. Four ethnographic research methods were incorporated: participant observation, ethnographic interviewing, search for artifacts, and auto-ethnographic researcher introspection (Eisenhart, 1988). After the interview transcripts, photos documenting past science fair participation, and researcher field notes were analyzed, patterns and themes emerged from the interviews that were supported in literature. American Indian academic success and life long learning are impacted by: (a) the effects of racism and oppression result in creating incredible obstacles to successful learning, (b) positive identity formation and the importance of family and community are essential in student learning, (c) the use of best practice in science education, including the use of curricular cultural integration for American Indian learners, supports student success, (d) the motivational need for student-directed educational opportunities (science fair/inquiry based research) is evident, (e) supportive teacher-student relationships in high school positively influences successful transitions into higher education.

  2. Bilingual communication methods, text versus video, to increase parent involvement and science fair project student achievement

    NASA Astrophysics Data System (ADS)

    Clevenson, Rhonda Suzanne

    This research examined the responses of families to bilingual communication methods, text versus video, designed to facilitate school to home communication to increase parent involvement and seventh grade student achievement in the science fair project. Using an experimental design, 161 families were randomly selected to receive either a two part informational text or video series during the science fair unit taught at a culturally diverse urban middle school. The bilingual informational materials were created and produced by the staff at the research site. Measures were taken to make sure all families could access the informational materials and innovations such as a special travel envelope and reminding procedures aided data collection. Surveys measuring variables on a Likert scale with spaces for comments were collected from the parents and students. An interrater reliability study was completed to measure the agreement of the two teachers who used a grading checklist to score science fair project achievement. Quantitative methods including ANOVA and MLR were used to examine the data in terms of student achievement and the communication method (text or video), audience (students and parents), and the anticipated outcome (parent help). Nonparametric and qualitative data analyses were used to explore how families used and responded to the informational materials. Significant results were that the video communication method was positively associated with student achievement on the science fair project. Significant main effects were observed for the student characteristics, educational services (general and special education, and English as a Second Language), and previous achievement in science, and the parent characteristics, previous experience with science fair projects, primary viewing language (English or Spanish), and expectations for student achievement. Student achievement was not significantly related to the amount or usefulness of parent help. The amount

    2012-04-01

    The physics program of the future FAIR facility covers a wide range of topics that address central issues of strong interactions and QCD. The antiproton beam of unprecedented quality in the momentum range from 1 to 15 GeV/c will allow to make high precision, high statistics measurements, from charmonium spectroscopy to the search for exotic hadrons and the study of nucleon structure, from the study of in-medium modifications of hadron masses to the physics of hypernuclei. These topics form the scientific program of the PANDA experiment.

  4. A Report on Stochastic Fairness Queueing (SFQ) Experiments

    NASA Technical Reports Server (NTRS)

    Denny, Barbara A.

    1993-01-01

    SRI International (SRI) has developed an improved queueing algorithm, known as Stochastic Fairness Queueing (SFQ), for best-effort traffic (i.e., traffic that does not require any guaranteed service). SFQ is a probablistic variant of strict fair queueing where instead of a single queue being allocated per flow, a fixed number of queues are used and a hash function maps the IP source and destination to a particular queue. A seed to the hash function is also perturbed occasionally to help distribute the flows amongst different queues when more than one flow maps to the same queue during the lifetime of the flow. SFQ provides 'fair' access by trying to ensure that each flow from source to destination host obtains equal access to the available bandwidth. This report covers a series of experiments performed on DARTnet evaluating the behavior and performance of SFQ against a FIFO queueing discipline. These experiments were designed to show SFQ's advantages and performance, and include tests demonstrating: Fair utilization of available resources; Starvation prevention; Graceful degradation under overload conditions; and Resource usage. In general, the experiments do show that SFQ is better than FIFO queueing at allocating bandwidth equally among a set of flows. SFQ also prevents a stream from dominating the available bandwidth, which seems to be a tendency with FIFO queueing (i.e., if a flow demands more than its share of the available bandwidth, with FIFO queueing that stream receives a disproportionate amount when compared to flows demanding less than their share). Furthermore, SFQ seems to reward 'nice' users of the network by providing a lower variance in delay and more throughput when their resource demand is less than their available share. Both SFQ and FIFO queueing seem to degrade fairly well as the network becomes saturated and to recover well as the network becomes less congested. Not unexpectedly, FIFO queueing is a little more efficient than SFQ-the delays are

    2014-01-29

    In the coming years the new international accelerator facility FAIR (Facility for Antiproton and Ion Research), one of the largest research projects worldwide, will be built at GSI. In the final construction FAIR consists of synchrotrons and storage rings with up to 1,100 meters in circumference, two linear accelerators and about 3.5 kilometers beam transfer lines. The existing GSI accelerators serve as pre-accelerators. Partly the new machines will consist of superconducting magnets and therefore require a reliable supply with liquid helium. As the requirements for the magnets is depending on the machine and have a high variety, the cooling system is different for each machine; two phase cooling, forced flow cooling and bath cooling respectively. In addition the cold mass of the individual magnets varies between less than 1t up to 80t and some magnets will cause a dynamic heat load due to ramping that is higher than the static loads. The full cryogenic system will be operated above atmospheric pressure. The refrigeration and liquefaction power will be provided by two main cryogenic plants of 8 and 25 kW at 4K and two smaller plants next to the experiments.

    TRB module is a multi-purpose Trigger and Readout Board with on-board DAQ functionality developed for the upgrade of the HADES experiment. It contains single computer chip (Etrax) running Linux and the 100 Mbit/s Ethernet interface. It has been orginally designed as the 128-channel Time to Digital Converter based on the HPTDC chip from CERN. The new version of TRB contains 2 Gbit/s optical link and interface connector (15 Gbit/s) implementing the add-on card concept and making the board more flexible. Moreover, FPGA chip (Xilinx, Virtex 4 LX 40) and TigerSharc DSP provide new computing resources which can be used to run on-line analysis algorithms. The TRB is proposed as a prototype of base readout module for the planned detector systems PANDA and CBM at the future FAIR facility at GSI-Darmstadt.

    The P-bar ANDA experiment (Pbar ANnihilations at DArmstadt) is a next generation hadron physics detector under design for the Facility for Antiproton and Ion Research (FAIR) at Darmstadt, Germany. It will be using cooled antiproton beams with an energy between 1.5 GeV and 15 GeV interacting with various internal targets.The experiment is focusing on hadron spectroscopy, in particular the search for exotic states in the charmonium region, on the interaction of charm hadrons with the nuclear medium and on double-hypernuclei.With physics requiring precise partial wave analysis the experiment has almost 4{pi} acceptance, a solenoid magnet for high p{sub T} tracks and a dipole magnet for the forward part of reaction products. A silicon vertex detector surrounds the interaction point. In both spectrometer parts tracking, charged particle identification, electromagnetic calorimetry and muon identification are available.The experiment is being designed to fully exploit the extraordinary physics potential arising from the availability of high-intensity, cooled antiproton beams.Significant progress beyond the present understanding of the field is expected thanks to improvements in statistics and precision of the data.

    2012-10-01

    For the past eight years, the Coalition for Plasma Science (CPS) has presented an award for a plasma project at the Intel International Science and Engineering Fair (ISEF). We reported on the first five years of this award at the 2009 DPP Symposium. Pulsed neutron-producing experiments are a recurring topic, with the efforts now turning to applications. The most recent award at the Pittsburgh ISEF this past May was given for analysis of data from Brookhaven's Relativistic Heavy Ion Collider. The effort had the goal of understanding the fluid properties of the quark-gluon plasma. All of the CPS award-winning projects so far have been based on experiments, with four awards going to women students and four to men. In 2009 we noted that the number and quality of projects was improving. Since then, as we we predicted (hoped for), that trend has continued. The CPS looks forward to continuing its work with students who are excited about the possibilities of plasma. You too can share this excitement by judging at the 2013 fair in Phoenix on May 12-17. Information may be obtained by emailing cps@plasmacoalition.org.

    2007-04-01

    Many organizations make an effort to reach the general public and children in the area of science understanding and appreciation. These include museums, universities, professional societies, government agencies, corporations and television networks. When studies are made of the composition of the audiences for many of these outreach programs one finds a great overlap. For example, those who like to go to science museums often enjoy viewing NOVA programs. The challenge is to bring Science to the People in places, times and venues not usual associated with science. For the past six years the Science & the Arts program at the Graduate Center of the City University of New York has made use of the performing arts to bring science to old and new audiences. See http://web.gc.cuny.edu/sciart. While this program has been effective, we have tried additional approaches in new modes and novel sites. In this paper we relate our experience with a citywide science festival, which we operated in New York City in November 2006. This idea was based on the science festival held in Atlanta in conjunction with the APS Centennial in 1999. We will review the history, effectiveness and various styles of Science Festivals in the United States and worldwide. In an even more adventurous outreach effort, in June 2006 our program rented booths at a conventional New York City weekend street fair, offering hands-on science experiences amidst the typical street fair food and wares. Adults and children were delighted to find science in this setting and welcomed the fact that they could get science with their tasty kielbasa sandwiches as well as a bargain on tube sox. Their responses were documented in a video. We will present parts of this video and offer suggestions for adapting this project to other locations

    2007-11-01

    Three years ago, the Coalition for Plasma Science (CPS) established a plasma prize at the Intel International Science and Engineering Fair. The APS/DPP and the IEEE/PSAC have helped make this effort a success by helping to identify judges. Each year since then, the number of plasma-related projects has increased. This year's prize was awarded for an instrument that, based on the ratio of spectral emission in two bands, detects when a high-pressure street light is about to fail. This allows time for an, efficient, scheduled replacement rather that an emergency service call. The CPS is a broadly-based group of institutions and individuals whose goal is to increase the understanding of plasmas for non-technical audiences. CPS activities include maintaining a website, http://www.plasmacoalition.org, developing educational literature, organizing educational luncheon presentations for Members of Congress and their staffs, and responding to questions about plasmas that are received by the CPS e-mail or toll-free number. The science fair prize and other CPS activities depend on the voluntary labor of CPS members and associates. New participants are needed to expand CPS activities and reach a larger audience. Send an e-mail to the CPS at CPS@plasmacoalition.org for information.

  16. Science Fairs and Observational Science: A Case History from Earth Orbit

    NASA Technical Reports Server (NTRS)

    Lowman, Paul D., Jr.; Smith, David E. (Technical Monitor)

    2002-01-01

    Having judged dozens of science fairs over the years, I am repeatedly disturbed by the ground rules under which students must prepare their entries. They are almost invariably required to follow the "scientific method," involving formulating a hypothesis, a test of the hypothesis, and then a project in which this test is carried out. As a research scientist for over 40 years, I consider this approach to science fairs fundamentally unsound. It is not only too restrictive, but actually avoids the most important (and difficult) part of scientific research: recognizing a scientific problem in the first place. A well-known example is one of the problems that, by his own account, stimulated Einstein's theory of special relativity: the obvious fact that when an electric current is induced in a conductor by a magnetic field , it makes no difference whether the field or the conductor is actually (so to speak) moving. There is in other words no such thing as absolute motion. Physics was transformed by Einstein's recognition of a problem. Most competent scientists can solve problems after they have been recognized and a hypothesis properly formulated, but the ability to find problems in the first Place is much rarer. Getting down to specifics, the "scientific method" under which almost all students must operate is actually the experimental method, involving controlled variables, one of which, ideally, is changed at a time. However, there is another type of science that can be called observational science. As it happens, almost all the space research I have carried out since 1959 has been this type, not experimental science.

  1. How to implement the Science Fair Self-Help Development Program in schools

    SciTech Connect

    Menicucci, D.

    1994-01-01

    This manual is intended to act as a working guide for setting up a Science Fair Volunteer Support Committee at your school. The Science Fair Volunteer Support Committee, or SFVSC, is the key component of the Science Fair Self-Help program, which was developed by Sandia National Laboratories and is designed to support a school`s science activities. The SFVSC is a team of parents and community volunteers who work in concert with a school`s teaching staff to assist and manage all areas of a school Science and Engineering Fair. The main advantage of creating such a committee is that it frees the science teachers from the organizational aspects of the fair and lets them concentrate on their job of teaching science. This manual is based on information gained through a Self-Help Development pilot program that was developed by Sandia National Laboratories during the 1991--92 school year at three Albuquerque, NM, middle schools. The manual describes the techniques that were successful in the pilot program and discusses how these techniques might be implemented in other schools. This manual also discusses problems that may be encountered, including suggestions for how they might be resolved.

  2. The experiment PANDA: physics with antiprotons at FAIR

    NASA Astrophysics Data System (ADS)

    Boca, Gianluigi

    2015-05-01

    PANDA is an experiment that will run at the future facility FAIR, Darmstadt, Germany. A high intensity and cooled antiproton beam will collide on a fixed hydrogen or nuclear target covering center-of-mass energies between 2.2 and 5.5 GeV. PANDA addresses various physics aspects from the low energy non-perturbative region towards the perturbative regime of QCD. With the impressive theoretical developments in this field, e.g. lattice QCD, the predictions are becoming more accurate in the course of time. The data harvest with PANDA will, therefore, be an ideal test bench with the aim to provide a deeper understanding of hadronic phenomena such as confinement and the generation of hadron masses. A variety of physics topics will be covered with PANDA, for example: the formation or production of exotic non-qqbar charm meson states connected to the recently observed XYZ spectrum; the study of gluon-rich matter, such as glueballs and hybrids; the spectroscopy of the excited states of strange and charm baryons, their production cross section and their spin correlations; the behaviour of hadrons in nuclear matter; the hypernuclear physics; the electromagnetic proton form factors in the timelike region. The PANDA experiment is designed to achieve the above mentioned physics goals with a setup with the following characteristics: an almost full solid angle acceptance; excellent tracking capabilities with high resolution (1-2 % at 1 GeV/c in the central region); secondary vertex detection with resolution ≈ 100 microns or better; electromagnetic calorimetry for detections of gammas and electrons up to 10 GeV; good particle identification of charge tracks (electrons, muons, pions, kaons, protons); a dedicated interchangeable central apparatus for the hypernuclear physics; detector and data acquisition system capable of working at 20 MHz interaction rate with an intelligent software trigger that can provide maximum flexibility.

  7. Ageism in science: fair-play between generations.

    PubMed

    Schroots, Johannes J

    2003-10-01

    This paper discusses the role of age in scientific practice from an ethical perspective. In social perception, people tend to categorise others rather automatically along three major dimensions: race, sex, and age. Much empirical and theoretical attention has been devoted to the study of racism and sexism, but comparatively little research in the social and behavioural sciences has been directed at understanding what some refer to as the third '-ism': ageism. For a serious understanding of the implications of ageism in science, it is necessary to discuss, first, the conflicting relationships between classical and modern concepts of time and calendar age, and thereafter the concept of ageism.

  11. The Silicon Tracking System of the CBM Experiment at FAIR

    NASA Astrophysics Data System (ADS)

    Heuser, Johann M.

    The Compressed Baryonic Matter (CBM) experiment at FAIR will conduct a systematic research program to explore the phase diagram of strongly interacting matter at highest net baryon densities and moderate temperatures. These conditions are to be created in collisions of heavy-ion beams with nuclear targets in the projectile beam energy range of 2 to 45 GeV/nucleon, initially coming from the SIS 100 synchrotron (up to 14 GeV/nucleon) and in a next step from SIS 300 enabling studies at the highest net baryon densities. Collision rates up to 107 per second are required to produce very rare probes with unprecedented statistics in this energy range. Their signatures are complex. These conditions call for detector systems designed to meet the extreme requirements in terms of rate capability, momentum and spatial resolution, and a novel data acquisition and trigger concept which is not limited by latency but by throughput. In the paper we describe the concept and development status of CBM's central detector, the Silicon Tracking System (STS). The detector realizes a large, highly granular and redundant detector system with fast read-out, and lays specific emphasis on low material budget in its physics aperture to achieve for charged particle tracks a momentum resolution of δp/p ≈ 1% at p > 1 GeV/c, at >95% track reconstruction efficiency. The detector employs 1220 highly segmented double-sided silicon micro-strip sensors of 300 µm thickness, mounted into 896 modular structures of various types that are aggregated on 106 low-mass carbon fiber ladders of different sizes that build up the tracking stations. The read-out electronics with its supply and cooling infrastructure is arranged at the periphery of the ladders, and provides a total channel count of 1.8 million. The signal transmission from the silicon sensors to the electronics is realized through ultra-thin multi-line aluminum-polyimide cables of up to half a meter length. The electronics generates a free

    The rapid expansion of remote sensing capability over the last two decades will take another major leap forward with the advent of the Earth Observing System (Eos). An approach is presented that will permit experiments and demonstrations in onboard information extraction. The approach is a non-intrusive, eavesdropping mode in which a small amount of spacecraft real estate is allocated to an onboard computation resource. How such an approach allows the evaluation of advanced technology in the space environment, advanced techniques in information extraction for both Earth science and information science studies, direct to user data products, and real-time response to events, all without affecting other on-board instrumentation is discussed.

    Potter, Melissa C.

    2009-12-01

    Presenting science fair projects gave students an opportunity to complete a performance assessment that comprised a meaningful task focused on process and subject to standards-based assessment. Students presented science inquiry and engineering design projects to judges at a regional science fair. The judges used the domains of the Potter Rubrics to assess the students' work and assigned a Quality score to each project. Using multiple regression, this study found that the mean scores on the Methods and Analysis domains predicted the mean Quality scores. Analyzing the technical quality of the Potter Rubrics addressed some of the measurement and generalizability concerns about performance assessments. Recommendations for future research and implications for practice were examined.

    The Priscilla and Bart Bok award, presented jointly by the Astronomical Society of the Pacific (ASP) and the American Astronomical Society (AAS) at the annual Intel International Science and Engineering Fair (ISEF), recognizes excellent research in astronomy conducted by high school students. The award is named in honor of two well-known astronomers. Bart Bok was an outstanding research astronomer: much of his research was done with his wife, Priscilla Fairfield Bok. Since 1992, the ASP and the AAS have shared the responsibility of sending three judges to the annual Intel ISEF to select two Bok awardees. Funds for the prizes themselves are derived from an endowment in Bart Bok’s honor held at the ASP. The Intel ISEF is a massive event. In order to become a finalist and attend ISEF, a student must first compete, and win one of the top awards, in both their local and regional science fairs. In recent years, about 1,500 high-school students have attended. About 100 of these students present projects in the category physics: of these, less than 20 are astronomy projects. Winners of the award are invited to attend the winter AAS meeting, and this year both of the 2012 winners are expected to be in attendance. There are also previous winners who are actively in our midst. But there is an unanswered question: why are there so few student projects in astronomy?

    The criteria for the selection of the experimental areas and individual experiments were that the experiment or area must make a meaningful contribution to the field of material science and that the space environment was either an absolute requirement for the successful execution of the experiment or that the experiment can be more economically or more conveniently performed in space. A number of experimental areas and individual experiments were recommended for further consideration as space experiments. Areas not considered to be fruitful and others needing additional analysis in order to determine their suitability for conduct in space are also listed. Recommendations were made concerning the manner in which these materials science experiments are carried out and the related studies that should be pursued.

    A simple, flexible and very low cost hardware plus software framework for developing computer-interfaced science experiments is presented. It can be used for developing computer-interfaced science experiments without getting into the details of electronics or computer programming. For developing experiments this is a middle path between push-button systems and the develop-from-scratch approach. Emphasis is on leveraging the power of personal computers for experiment control, data acquisition and the mathematical analysis of data. The language 'Python' is chosen for data acquisition and analysis. This article explains the architecture of Phoenix (Physics with Home-made Equipment and Innovative Experiments) along with some sample experiments. The hardware design is open and the project is totally based on free software.

  14. Authorship and responsibility in health sciences research: a review of procedures for fairly allocating authorship in multi-author studies.

    PubMed

    Smith, Elise; Williams-Jones, Bryn

    2012-06-01

    While there has been significant discussion in the health sciences and ethics literatures about problems associated with publication practices (e.g., ghost- and gift-authorship, conflicts of interest), there has been relatively little practical guidance developed to help researchers determine how they should fairly allocate credit for multi-authored publications. Fair allocation of credit requires that participating authors be acknowledged for their contribution and responsibilities, but it is not obvious what contributions should warrant authorship, nor who should be responsible for the quality and content of the scientific research findings presented in a publication. In this paper, we review arguments presented in the ethics and health science literatures, and the policies or guidelines proposed by learned societies and journals, in order to explore the link between author contribution and responsibility in multi-author multidisciplinary health science publications. We then critically examine the various procedures used in the field to help researchers fairly allocate authorship. PMID:21312000

    The Compressed Baryonic Matter (CBM) experiment at GSI's future international Facility for Antiproton and Ion Research (FAIR) will study strongly interacting matter at high baryon densities. The central component of the fixed-target heavy-ion spectrometer is a high-performance silicon vertex tracker. It applies most advanced pixel and microstrip detectors to track exclusively the charged particles created in the collisions and to reconstruct decay vertices from 'open charm'. The development of the silicon tracker is challenging and includes R and D on ultra low-mass sensors and support structures, extreme radiation hardness, and fast self-triggered readout.

    2015-12-01

    The R3B (Reactions with Rare Radioactive Beams) experiment is one of the planned experiments at the future FAIR facility at GSI Darmstadt. R3B will cover experimental reaction studies with exotic nuclei far off stability, thus enabling a broad physics program with rare-isotope beams with emphasis on nuclear structure and dynamics. Several different detection subsystems as well as sophisticated DAQ system and data-analysis software are being developed for this purpose. The data analysis software for R3B is based on FairRoot framework and called R3BRoot. R3BRoot is being used for simulation and detector design studies for the last few years. Recently, it was successfully used directly with the data acquisition and for the analysis of the R3B test beam-time in April 2014. For the future beam times the framework has to deal with the free streaming readout of the detectors. The implementation within R3BRoot to fulfil this trigger-less run mode will be discussed in this paper, as well as the set of tools developed for the online reconstruction and quality assurance of the data during the run.

    FAIR -- the Facility for Antiproton and Ion Research in Europe -- constructed at GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt comprises an international centre of heavy ion accelerators that will drive heavy ion and antimatter research (FBTR, 2006). FAIR will provide worldwide unique accelerator and experimental facilities allowing a large variety of fore-front research in physics and applied science. FAIR will deliver antiproton and ion beams of unprecedented intensities and qualities. The main part of the FAIR facility is a sophisticated and cost efficient accelerator system, which delivers parallel beams to different experiments of the FAIR experimental collaborations -- APPA, NuSTAR, CBM and PANDA. The accelerated primary beams will then be employed to create new, often highly exotic particles in a series of parallel experimental programs. Experiments with exotic particles will explore fundamental processes which are expected to have taken place in the early phases and still happen in the on-going evolution of the Universe. These processes produced the basic constituents of matter and overall structure we observe today...

    P̅ANDA is a future hadron and nuclear physics experiment at the FAIR facility in construction in Darmstadt, Germany. In contrast to the majority of current experiments, PANDA's strategy for data acquisition is based on event reconstruction from free-streaming data, performed in real time entirely by software algorithms using global detector information. This paper reports the status of the development of algorithms for the reconstruction of charged particle tracks, optimized online data processing applications, using General-Purpose Graphic Processing Units (GPU). Two algorithms for trackfinding, the Triplet Finder and the Circle Hough, are described, and details of their GPU implementations are highlighted. Average track reconstruction times of less than 100 ns are obtained running the Triplet Finder on state-of- the-art GPU cards. In addition, a proof-of-concept system for the dispatch of data to tracking algorithms using Message Queues is presented.

  1. More Fair Play in an Ultimatum Game after Resettlement in Zimbabwe: A Field Experiment and a Structural Model

    PubMed Central

    Kohler, Stefan

    2013-01-01

    Zimbabwean villagers of distinct background have resettled in government-organized land reforms for more than three decades. Against this backdrop, I assess the level of social cohesion in some of the newly established communities by estimating the average preferences for fairness in a structural model of bounded rationality. The estimations are based on behavioral data from an ultimatum game field experiment played by 234 randomly selected households in 6 traditional and 14 resettled villages almost two decades after resettlement. Equal or higher degrees of fairness are estimated in all resettlement schemes. In one, or arguably two, out of three distinct resettlement schemes studied, the resettled villagers exhibit significantly higher degrees of fairness ( ) and rationality ( ) than those who live in traditional villages. Overall, villagers appear similarly rational, but the attitude toward fairness is significantly stronger in resettled communities ( ). These findings are consistent with the idea of an increased need for cooperation required in recommencement. PMID:23724095

    In 2007 NEPTUNE Canada will install the first stage of a regional cabled observatory (RCO) in the northeast Pacific Ocean. Stage 2 of the RCO is being developed by the US-based ORION Project Office, through the National Science Foundation's Ocean Observatory Initiative (OOI). For Stage 1, a 800km fiber-optic cable will loop out from a shore station on Vancouver Island to the Juan de Fuca volcanic spreading ridge. Two seafloor nodes are planned, one to support studies of tectonic and hydrothermal activity on the Endeavour Segment of the Juan de Fuca Ridge, and the other for investigation of a broad range of processes in Barkley Canyon, on the continental slope of Vancouver Island. Each node will provide power and Ethernet communications to instruments that comprise multi-disciplinary community science experiments. These experiments were developed through a 2-year series of workshops and a final competition. Data from all instruments will be available on-line, through the NEPTUNE data management and archive system. Investigations at the Endeavour node will focus on links between seismic activity and hydrothermal emissions and their resulting impact on hydrothermal vent organisms and regional oceanic circulation and geochemical fluxes. This area provides a number of technical challenges, including the laying of the backbone cable over a volcanic terrain, and the placement of instruments and extension cables in areas of abundant high-temperature venting. Planned instruments include broad-band seismometers, acoustic Doppler current meters, video and digital still cameras and chemical sensors. Experiments at the Barkley Canyon site will emphasis the effects of water currents passing through the canyon, and seismic activity. Combined biological and physical oceanographic instruments will monitor the interaction between sediment transport along the axis of the canyon and the bioturbation activity of the fauna.

    2011-05-01

    The P¯ANDA experiment at FAIR will perform high precision experiments in the charmed quark sector using cooled antiproton beams of unprecedented intensities of L=2×10 32 cm -2 s -1 in the momentum range of 1-15 GeV/ c. The charged particle identification in the barrel region needs a thin detector operating in a strong magnetic field. A ring imaging Cherenkov detector using the DIRC principle is an excellent match to those requirements. This article describes aspects of the design and R&D for the P¯ANDA barrel DIRC detector. The availability of highly pixelated fast photon detectors allows several key improvements compared to the successful BaBar-DIRC detector, some of which were tested in a proton beam at GSI. The optical properties of the radiator bars, made from synthetic fused silica, are critical to the success of the DIRC. Measurements of the attenuation length and reflection coefficient allow the determination of the surface roughness of prototype radiator bars.

    Antequera, A. T.; Espinel, M. C.

    2011-03-01

    The aim of this study is twofold. The first is to investigate the ability of secondary school students to understand the different distribution schemes and thus, indirectly, to contribute to the educational discussion and approach to be used for distribution problems so as to lessen reliance on the ubiquitous cross-multiplication rule in proportional distribution. The experiment was conducted with secondary school students using a specifically devised scenario involving a distribution problem. We present an analysis of the students' performance with respect to their concept of fair distribution in a given situation. Their ability to apply the various rules in a new situation is determined. The results provide an insight into the possibilities offered by teaching different distribution methods, especially with mathematically gifted students. The second aim is for instructors to appreciate the value of teaching other distribution methods that apply in real life in addition to a proportional distribution so that they may include in the mathematics classes some recently developed concepts from the field of cooperative game theory.

    Lebedev, A.; Höhne, C.; Kisel, I.; Ososkov, G.

    2010-07-01

    Particle trajectory recognition is an important and challenging task in the Compressed Baryonic Matter (CBM) experiment at the future FAIR accelerator at Darmstadt. The tracking algorithms have to process terabytes of input data produced in particle collisions. Therefore, the speed of the tracking software is extremely important for data analysis. In this contribution, a fast parallel track reconstruction algorithm which uses available features of modern processors is presented. These features comprise a SIMD instruction set (SSE) and multithreading. The first allows one to pack several data items into one register and to operate on all of them in parallel thus achieving more operations per cycle. The second feature enables the routines to exploit all available CPU cores and hardware threads. This parallel version of the tracking algorithm has been compared to the initial serial scalar version which uses a similar approach for tracking. A speed-up factor of 487 was achieved (from 730 to 1.5 ms/event) for a computer with 2 × Intel Core i7 processors at 2.66 GHz.

    2016-07-01

    The barrel time-of-flight detector for the PANDA experiment at FAIR is foreseen as a Scintillator Tile (SciTil) Hodoscope based on several thousand small plastic scintillator tiles read-out with directly attached Silicon Photomultipliers (SiPMs). The main tasks of the system are an accurate determination of the time origin of particle tracks to avoid event mixing at high collision rates, relative time-of-flight measurements as well as particle identification in the low momentum regime. The main requirements are the use of a minimum material amount and a time resolution of σ < 100 ps. We have performed extensive optimization studies and prototype tests to prove the feasibility of the SciTil design and finalize the R&D phase. In a 2.7 GeV/c proton beam at Forschungszentrum Jülich a time resolution of about 80 ps has been achieved using SiPMs from KETEK and Hamamatsu with an active area of 3 × 3mm2. Employing the Digital Photon Counter from Philips a time resolution of about 30 ps has been reached.

  9. Hypernuclear physics studies of the P̅ANDA experiment at FAIR

    NASA Astrophysics Data System (ADS)

    Sanchez Lorente, Alicia

    2015-05-01

    Hypernuclear research will be one of the main topics addressed by the PANDA experiment at the planned Facility for Antiproton and Ion Research FAIR at Darmstadt (Germany). [1, 2] Thanks to the use of stored p̅ beams, copious production of double Λ hypernuclei is expected at the PANDA experiment, which will enable high precision γ spectroscopy of such nuclei for the first time, and consequently a unique chance to explore the hyperon-hyperon interaction. In particular, ambiguities of past experiments in determining the strength of the ΛΛ interaction will be avoided thanks to the excellent energy precision of a few keV (FWHM) achieved by germanium detectors. Such a resolution capability is particularly needed to resolve the small energy spacing of the order of (10-100) keV, which is characteristic from the spin doublet in hypernuclei the so -called "hypernuclear fine structure". In comparison to previous experiments, PANDA will benefit from a novel technique to assign the various observable γ-transitions in a unique way to specific double hypernuclei by exploring various light targets. Nevertheless, the ability to carry out unique assignments requires a devoted hypernuclear detector setup. This consists of a primary nuclear target for the production of Ξ- + overline Xi pairs, a secondary active target for the hypernuclei formation and the identification of associated decay products and a germanium array detector to perform γ spectroscopy. Moreover, one of the most challenging issues of this project is the fact that all detector systems need to operate in the presence of a high magnetic field and a large hadronic background. Accordingly, the need of an innovative detector concept will require dramatic improvements to fulfil these conditions and that will likely lead to a new generation of detectors. In the present work details concerning the current status of the activities related to the detector developments for this challenging programme will be given. Among

  11. Teacher learning from girls' informal science experiences

    NASA Astrophysics Data System (ADS)

    Birmingham, Daniel J.

    School science continues to fail to engage youth from non-dominant communities (Carlone, Huan-Frank & Webb, 2011). However, recent research demonstrates that informal science learning settings support both knowledge gains and increased participation in science among youth from non-dominant communities (Dierking, 2007; Falk et al., 2007; HFRP, 2010). Despite the success, little is known about how teachers can learn from informal science practices to support student engagement in science. In this study, I examine the impact informal science experiences has for the teaching and learning of science in school contexts. This study is focused on eliciting girls' stories of informal science learning experiences and sharing these stories with science teachers to examine what they notice and make meaning of in connection with their classroom practices (van Es & Sherin, 2002). I co-constructed cases of informal science experiences with middle school females who participate in an after school science program in an urban area. These cases consisted of the girls' written stories, their explicit messages to science teachers, examples of actions taken when investigating community based science issues and transcripts of conversations between the girls and researchers. These cases were shared with local science teachers in order to investigate what they "notice" (van Es & Sherin, 2002) regarding girls' participation in informal science learning, how they make meaning of youths' stories and whether the stories influence their classroom practices. I found that the girls' use their cases to share experiences of how, where and why science matters, to express hope for school science and to critique stereotypical views that young, female, students of color from lower SES backgrounds are not interested or capable of making contributions to scientific investigations. Additionally, I found that teachers noticed powerful messages within and across the girls' cases. The messages include; 1

    The Multispectral Thermal Imager (MTI) is a technology test and demonstration satellite whose primary mission involved a finite number of technical objectives. MTI was not designed, or supported, to become a general purpose operational satellite. The role of the MTI science team is to provide a core group of system-expert scientists who perform the scientific development and technical evaluations needed to meet programmatic objectives. Another mission for the team is to develop algorithms to provide atmospheric compensation and quantitative retrieval of surface parameters to a relatively small community of MTI users. Finally, the science team responds and adjusts to unanticipated events in the life of the satellite. Broad or general lessons learned include the value of working closely with the people who perform the calibration of the data as well as those providing archived image and retrieval products. Close interaction between the Los Alamos National Laboratory (LANL) teams was very beneficial to the overall effort as well as the science effort.

  19. More fair play in an ultimatum game after resettlement in Zimbabwe: a field experiment and a structural model.

    PubMed

    Kohler, Stefan

    2013-01-01

    Zimbabwean villagers of distinct background have resettled in government-organized land reforms for more than three decades. Against this backdrop, I assess the level of social cohesion in some of the newly established communities by estimating the average preferences for fairness in a structural model of bounded rationality. The estimations are based on behavioral data from an ultimatum game field experiment played by 234 randomly selected households in 6 traditional and 14 resettled villages almost two decades after resettlement. Equal or higher degrees of fairness are estimated in all resettlement schemes. In one, or arguably two, out of three distinct resettlement schemes studied, the resettled villagers exhibit significantly higher degrees of fairness (p ≤ 0.11) and rationality (p ≤ 0.04) than those who live in traditional villages. Overall, villagers appear similarly rational, but the attitude toward fairness is significantly stronger in resettled communities (p ≤ 0.01). These findings are consistent with the idea of an increased need for cooperation required in recommencement. PMID:23724095

    This paper describes the microgravity materials experiments carried out on the Shuttle/Mir program. There were six experiments, all of which investigated some aspect of diffusivity in liquid melts. The Liquid Metal Diffusion (LMD) experiment investigated the diffusivity of molten Indium samples at 185 C using a radioactive tracer, In-114m. By monitoring two different gamma ray energies (190 keV and 24 keV) emitted by the samples it was possible to measure independently the diffusion rates in the bulk and at the surface of the samples. The Queens University Experiment in Liquid Diffusion (QUELD) was the furnace facility used to process 213 samples for the five other experiments. These experiments investigated the diffusion, ripening, crystal growth, and glass formation in metal, semiconductor, and glass samples. This facility had the capability to process samples in an isothermal or gradient configuration for varying periods of time at temperatures up to 900 C. Both the LMD and the QUELD furnaces were mounted on the Microgravity Isolation Mount (MIM) which provided isolation from g-jitter. All the microgravity experiments were supported by the Space Acceleration Measurement System (SAMS); a three head three axes acceleration monitoring system which measured and recorded the acceleration environment.

    A promising microcomputer configuration for the Spacelab Life Sciences Lab. Equipment inventory consists of multiple processors. One processor's use is reserved, with additional processors dedicated to real time input and output operations. A simple form of such a configuration, with a processor board for analog to digital conversion and another processor board for digital to analog conversion, was studied. The system used digital parallel data lines between the boards, operating independently of the system bus. Good performance of individual components was demonstrated: the analog to digital converter was at over 10,000 samples per second. The combination of the data transfer between boards with the input or output functions on each board slowed performance, with a maximum throughput of 2800 to 2900 analog samples per second. Any of several techniques, such as use of the system bus for data transfer or the addition of direct memory access hardware to the processor boards, should give significantly improved performance.

    While studies investigating the health effects of racial discrimination for children and youth have examined a range of effect modifiers, to date, relationships between experiences of racial discrimination, student attitudes, and health outcomes remain unexplored. This study uniquely demonstrates the moderating effects of vicarious racism and motivated fairness on the association between direct experiences of racism and mental health outcomes, specifically depressive symptoms and loneliness, among primary and secondary school students. Across seven schools, 263 students (54.4% female), ranging from 8 to 17 years old (M = 11.2, SD = 2.2) reported attitudes about other racial/ethnic groups and experiences of racism. Students from minority ethnic groups (determined by country of birth) reported higher levels of loneliness and more racist experiences relative to the majority group students. Students from the majority racial/ethnic group reported higher levels of loneliness and depressive symptoms if they had more friends from different racial/ethnic groups, whereas the number of friends from different groups had no effect on minority students' loneliness or depressive symptoms. Direct experiences of racism were robustly related to higher loneliness and depressive symptoms in multivariate regression models. However, the association with depressive symptoms was reduced to marginal significance when students reported low motivated fairness. Elaborating on the negative health effects of racism in primary and secondary school students provides an impetus for future research and the development of appropriate interventions. PMID:24903675

    The present paper describes an experience of science theatre addressed to children of primary and secondary school, with the main purpose of explaining the Earth interior while raising awareness about natural hazard. We conducted the experience with the help of a theatrical company specialized in shows for children. Several performances have been reiterated in different context, giving us the opportunity of conducting a preliminary survey with public of different ages, even if the show was conceived for children. Results suggest that science theatre while relying on creativity and emotional learning in transmitting knowledge about the Earth and its hazard has the potential to induce in children a positive attitude towards the risks

  13. How high school science-related experiences influenced science career persistence

    NASA Astrophysics Data System (ADS)

    Shaw, Andrew D.

    The events of 9/11 brought into focus two ongoing trends that were present before this tragedy and have continued since: (1) The United States needs more scientists if it is to ensure its freedoms and maintain its economy. (2) The number of scientists in the "pipeline" is declining because of the diminished presence of foreign scientists (they are wanted in their own countries), the under-representation of minorities and women, and the reduced numbers of students able and willing to take on the scholastic rigors necessary for a science or engineering degree. Though much has been written about improving science education, and numerous projects have been conducted to promote it, few education researchers have questioned the scientists themselves about the experiences, practices, and people that positively influenced them, particularly during their pre-college years. Towards this end, thirty-two scientists were interviewed in order to address four research questions: (1) How did practicing scientists' personal relationships with their science teachers influence their decision to pursue a career in science? (2) What pedagogical methods (e.g. lectures, demonstrations, "hands-on" work, problem solving, small groups) used in their high school science courses, if any, played a significant role in propelling certain students towards a career as a practicing scientist? (3) What high school science-related support structures (e.g. labs, equipment, textbooks, technology), if any, played a significant role in propelling certain students towards a career as a practicing scientist? (4) What high school science-related educational activities (e.g. science fairs, clubs, summer internships), if any, played a significant role in propelling certain students towards a career as a practicing scientist? Some of the scientists reported that they knew they were headed towards a career in science before they even entered high school, while others did not make a decision about a science

  17. School Teachers' Experiences of Science Curriculum Reform

    NASA Astrophysics Data System (ADS)

    Ryder, Jim; Banner, Indira

    2013-02-01

    We examine teachers' experiences of a major reform of the school science curriculum for 14-16-year olds in England. This statutory reform enhances the range of available science courses and emphasises the teaching of socio-scientific issues and the nature of science, alongside the teaching of canonical science knowledge. This paper examines teachers' experiences of the reform and the factors that condition these experiences. A designed sample of 22 teachers discussed their experiences of the reform within a semi-structured interview. Our analysis considers how the external and internal structures within which teachers work interact with the personal characteristics of teachers to condition their experiences of the curriculum reform. In many cases, personal/internal/external contexts of teachers' work align, resulting in an overall working context that is supportive of teacher change. However, in other cases, tensions within these contexts result in barriers to change. We also explore cases in which external curriculum reform has stimulated the development of new contexts for teachers' work. We argue that curriculum reformers need to recognise the inevitability of multiple teaching goals within a highly differentiated department and school workplace. We also show how experiences of curriculum reform can extend beyond the learning of new knowledge and associated pedagogies to involve challenges to teachers' professional identities. We argue for the extended use of teacher role models within local communities of practice to support such 'identity work'.

    How to integrate simulation-based engineering and science (SBES) into the science curriculum smoothly is a challenging question. For the importance of SBES to be appreciated, the core value of simulations-that they help people understand natural phenomena and solve engineering problems-must be taught. A strategy to achieve this goal is to introduce computational experiments to the science curriculum to replace or supplement textbook illustrations and exercises and to complement or frame hands-on or wet lab experiments. In this way, students will have an opportunity to learn about SBES without compromising other learning goals required by the standards and teachers will welcome these tools as they strengthen what they are already teaching. This paper demonstrates this idea using a number of examples in physics, chemistry, and engineering. These exemplary computational experiments show that it is possible to create a curriculum that is both deeper and wider.

    On November 26, 2011, the Mars Science Laboratory (MSL) launched from Florida's Cape Canaveral Air Force Station aboard an Atlas V 541 rocket, taking its first step toward exploring the past habitability of Mars' Gale Crater. Because microbial contamination could profoundly impact the integrity of the mission, and compliance with international treaty was a necessity, planetary protection measures were implemented on all MSL hardware to verify that bioburden levels complied with NASA regulations. The cleanliness of the Atlas V payload fairing (PLF) and associated ground support systems used to launch MSL were also evaluated. By applying proper recontamination countermeasures early and often in the encapsulation process, the PLF was kept extremely clean and was shown to pose little threat of recontaminating the enclosed MSL flight system upon launch. Contrary to prelaunch estimates that assumed that the interior PLF spore burden ranged from 500 to 1000 spores/m², the interior surfaces of the Atlas V PLF were extremely clean, housing a mere 4.65 spores/m². Reported here are the practices and results of the campaign to implement and verify planetary protection measures on the Atlas V launch vehicle and associated ground support systems used to launch MSL. All these facilities and systems were very well kept and exceeded the levels of cleanliness and rigor required in launching the MSL payload. PMID:24432777

  20. Continuous-Readout Simulation with FairRoot on the Example of the P̅ANDA Experiment

    NASA Astrophysics Data System (ADS)

    Stockmanns, Tobias

    2015-12-01

    Future particle physics experiments are searching more and more for rare decays which have similar signatures in the detector as the huge background. For those events usually simple selection criteria do not exist, which makes it impossible to implement a hardware- trigger based on a small subset of detector data. Therefore, all the detector data is read out continuously and processed on-the-fly to achieve a data reduction suitable for permanent storage and detailed analysis. To cope with these requirements of a triggerless readout, also the simulation software has to be adopted to add a continuous data production with pile-up effects and event overlapping in addition to the event-wise simulation. This simulated data is of utmost importance to get a realistic detector simulation, to develop event-building algorithms and to determine the hardware requirements for the DAQ system of the experiments. The possibility to simulate a continuous data stream was integrated into the FairRoot simulation framework. This running mode is called time-based simulation and a lot of effort was taken that one can switch seamlessly between the event-based and the time-based simulation mode. One experiment, which is using this new feature, is the PANDA experiment. It utilizes a quasicontinuous antiproton beam with a mean time between interactions of 50 ns. Because of the unbunched structure of the beam the interaction time follows a Poisson statistic with a high probability of events with short time distances. Depending on the time resolution of the subdetectors this leads to an overlap of up to 20 events inside a sub-detector. This makes it an ideal test candidate for the time-based simulation. In the following text an overview of the implementation of the time-based simulation mode in FairRoot is given and some examples for the P̅ANDA experiment are shown.

    Despite recommendations for screening for hepatitis B virus (HBV) and hepatitis C virus (HCV), most individuals are still unaware of their infection status. The disparities in screening for HBV and HCV can be attributed to lack of awareness, language barriers, and difficulty in accessing healthcare. To address these issues, an exhibit booth was set up at an annual cultural festival to promote awareness about HBV and HCV and also provide free screening for a local Floridian community. Recruitment was conducted in various languages by physicians and nurses who specialize in hepatology. All materials associated with the screening process were sponsored by the Schiff Center for Liver Diseases, which is located at the University of Miami Miller School of Medicine in Florida. In the first year of the screening initiative, 173 of 11,000 fair attendees were screened for HBV. Twenty-nine (17%) of those screened tested positive for antibodies to hepatitis B core antigen (anti-HBc), and only 1 individual tested positive for chronic HBV, with positive hepatitis B surface antigen (HBsAg). Screening for HCV and an extended patient questionnaire were added to the screening program in the second year of the initiative. A total 231 of 9,000 fair attendees volunteered to be screened for both HBV and HCV. Twenty-nine (13%) of these people tested positive for anti-HBc, and 3 tested positive for HBsAg. Only 1 person tested positive for anti-HCV, but this individual had undetectable HCV RNA levels. Our single-center experience illustrates that, despite efforts to improve access to screening, only 2-3% of attendees at a cultural fair embraced the screening efforts. Other strategies will be required to enhance participation in screening programs for viral hepatitis. PMID:23943664

  2. ATM traffic experiments: A laboratory study of service interaction, loss fairness and loss characteristics

    1995-04-01

    A reference measurement scenario is defined, where an ATM switch (OCTOPUS) is offered traffic from three source types representing the traffic resulting from typical services to be carried by an ATM network. These are high quality video (HQTV), high speed data (HSD) and constant bitrate transfer (CBR). In addition to be typical, these have widely different characteristics. Detailed definitions for these, and other actual source types, are made and entered into the Synthetic Traffic Generator (STG) database. Recommended traffic mixes of these sources are also made. Based on the above, laboratory measurements are carried out to study how the various kinds of traffic influence each other, how fairly the loss is distributed over services and connections, and what are the loss characteristics experienced. (Due to a software error detected in the measurement equipment after the work was concluded, the measurements are carried out with a HSD source with a load less 'aggressive' than intended.) The main findings are: Cell loss is very unfairly distributed among the various connections. During a loss burst, which occurs less frequently than the duration of a typical connection, affects mainly one or a few connections; Cell loss is unfairly distributed among the services. The ratios in the range from HSD: HQTV: CBR = 5 : 1 : 0.85 are observed, and unfairness increases with decreasing load burstiness; The loss characteristics vary during a loss burst, from one burst to the next and between services. Hence, it does not seem feasible to use 'typical-loss-statistics' to study the impairments on various services. In addition some supplementing work is reported.

Slowik, Gymnasium No. 2 in Zielona Gora, Poland Our School - Gymnasium No. 2 in Zielona Gora - where pupils' age is 13 -16, has for many years organized a lot of exciting events popularizing science among Zielona Gora children and young people, in particular experimental physics and astronomy. The best known in our town is the regular event on physics, - called the physical Festival of Zielona Gora, of which I am the main initiator and organizer. The Festival is directed to students of the last classes of Zielona Góra primary schools. During the Festivities their shows have also physicists and astronomers, from cooperating with us in popularization of science Zielona Gora University. At the festival the students from our Experimental School Group "Archimedes". Presented their own prepared themselves physical experience. With considerable help of students of Gymnasium No. 2 interested in astronomy, we organize the cyclical event, named "Cosmic Santa Claus," where I share with the students the knowledge gained through my active annual participation in the Space Workshop organized by the Science Centre in Warsaw. We all have fun and learn in a great way and with a smile, we touch real science that reveals its secrets!

    Nuclear ground state properties including mass, charge radii, spins and moments can be determined by applying atomic physics techniques such as Penning-trap based mass spectrometry and laser spectroscopy. The MATS and LaSpec setups at the low-energy beamline at FAIR will allow us to extend the knowledge of these properties further into the region far from stability. The mass and its inherent connection with the nuclear binding energy is a fundamental property of a nuclide, a unique “fingerprint”. Thus, precise mass values are important for a variety of applications, ranging from nuclear-structure studies like the investigation of shell closures and the onset of deformation, tests of nuclear mass models and mass formulas, to tests of the weak interaction and of the Standard Model. The required relative accuracy ranges from 10-5 to below 10-8 for radionuclides, which most often have half-lives well below 1 s. Substantial progress in Penning trap mass spectrometry has made this method a prime choice for precision measurements on rare isotopes. The technique has the potential to provide high accuracy and sensitivity even for very short-lived nuclides. Furthermore, ion traps can be used for precision decay studies and offer advantages over existing methods. With MATS (Precision Measurements of very short-lived nuclei using an A_dvanced Trapping System for highly-charged ions) at FAIR we aim to apply several techniques to very short-lived radionuclides: High-accuracy mass measurements, in-trap conversion electron and alpha spectroscopy, and trap-assisted spectroscopy. The experimental setup of MATS is a unique combination of an electron beam ion trap for charge breeding, ion traps for beam preparation, and a high-precision Penning trap system for mass measurements and decay studies. For the mass measurements, MATS offers both a high accuracy and a high sensitivity. A relative mass uncertainty of 10-9 can be reached by employing highly-charged ions and a non

    Baryon-to-meson Transition Distribution Amplitudes (TDAs) encoding valuable new information on hadron structure appear as building blocks in the collinear factorized description for several types of hard exclusive reactions. In this paper, we address the possibility of accessing nucleon-to-pion ( πN) TDAs from reaction with the future P¯ANDA detector at the FAIR facility. At high center-of-mass energy and high invariant mass squared of the lepton pair q 2, the amplitude of the signal channel admits a QCD factorized description in terms of πN TDAs and nucleon Distribution Amplitudes (DAs) in the forward and backward kinematic regimes. Assuming the validity of this factorized description, we perform feasibility studies for measuring with the P¯ANDA detector. Detailed simulations on signal reconstruction efficiency as well as on rejection of the most severe background channel, i.e. were performed for the center-of-mass energy squared s = 5 GeV2 and s = 10 GeV2, in the kinematic regions 3.0 < q 2 < 4.3 GeV2 and 5 < q 2 GeV2, respectively, with a neutral pion scattered in the forward or backward cone in the proton-antiproton center-of-mass frame. Results of the simulation show that the particle identification capabilities of the P¯ANDA detector will allow to achieve a background rejection factor of 5 · 107 (1 · 107) at low (high) q 2 for s = 5 GeV2, and of 1 · 108 (6 · 106) at low (high) q 2 for s = 10 GeV2, while keeping the signal reconstruction efficiency at around 40%. At both energies, a clean lepton signal can be reconstructed with the expected statistics corresponding to 2 fb-1 of integrated luminosity. The cross sections obtained from the simulations are used to show that a test of QCD collinear factorization can be done at the lowest order by measuring scaling laws and angular distributions. The future measurement of the signal channel cross section with P¯ANDA will provide a new test of the perturbative QCD description of a novel class of hard

  7. Experiment Prevails Over Observation in Geophysical Science

    Thomson and Tait gave their name to a text (T and T') that sums up nineteenth century mechanics. T and T' says that scientists gain knowledge of the natural universe and the laws that regulate it through Experience. T and T' divides Experience into Observation and Experiment. The posthumous (1912) edition of T and T' appeared seven years before Eddington's expeditions to observe the eclipse of 29 May 1919 that demonstrated the bending of starlight predicted by Einstein's general theory of relativity. During the 2005 centenary of young Einstein's remarkably productive year, Eddington's (1919) result was frequently remembered, but the description in 2005 of what Eddington did in 1919 often differed from what Eddington said that he did. In his words then, Eddington observed; in words from scientists, historians of science, and philosophers of science during 2005, Eddington often experimented. In 1912, T and T' had distinguished Observation from Experiment with an apt contrast: ""When, as in astronomy, we endeavour to ascertain these causes by simply watching, we observe; when, as in our laboratories, we interfere arbitrarily with the causes or circumstances of a phenomenon, we are said to experiment"". (italics in T and T'). Eddington himself conformed to this distinction in his report (Physical Society of London, 1920). In its Preface, he states that observations were made at each of two stations, and concludes that ""I think it may now be stated that Einstein's law of gravitation is definitely established by observation..."". Chapter V of that report deals with The Crucial Phenomena. In this chapter, some form of the word observe (noun, verb, adjective, adverb) appears 13 times. In this chapter, experiment appears only as experimental, and then only twice. Einstein's prediction, with Eddington's observations, profoundly impressed contemporary philosophers of science. Karl Popper, then aged 17, considered Eddington's findings to effect a turning point in his career

  9. Public Science with Real-Time Experiments

    2013-12-01

    One of the best ways for professional scientists to engage in public outreach is to get outside of the university and/or lab walls and go out into the public. That is, go to public spaces to do some science experiments with the public - this includes students of all ages that constitute that public. Technological advance in portable measurement gear now allow one to do real, or near real, time experiments in outdoor, public spaces. We have been running a meta-experiment of this sort, aimed at the public display of science, for about a year now in Houston TX at the Lee and Joe Jamail Skatepark. The project goes under the title of Sk8Lab Houston and has introduced students of all ages to the power of scientific experimentation. We bring a portable science pack with us to the park. The pack has a range of wireless measurement gear that allow experiments to be done on the spot. Some of the experiments are designed by us but many are designed on by whoever suggests them to us that day. Over time the Sk8Lab scientists have built up a level of "trust" with the people who frequent the park (no one feels like we are gonna grade them at the park and they know that the learning is not on some regimented clock). This has broken down some learning walls and allowed for a more informal mode of exploration and a more genuine mode of experimentation (as compared to what often happens in class labs when students feel like they are just being forced to reproduce some known result). We will describe some of the test case experiments we have run and also discuss some of the trials, tribulations, and happy successes (many unplanned) along the way.

    High energy density science probes some of the most basic scientific questions that cut across traditional disciplines. The advent of table top, terawatt, femtosecond lasers promises to revolutionize this area by the use of precise experimental techniques on the one hand and testing of models and computer simulations on the other. In this paper, we present some of our results on hot electron generation, giant magnetic fields and ultrafast plasma dynamics using such experiments and theoretical modeling.

    Precision experiments with relativistic fragments separated in-flight require special experimentalmethods to overcome the inherent large emittance from the creation in nuclear reactions and atomic interactions in matter. At GSI relativistic exotic nuclei have been produced via uranium projectile fragmentation and fission and investigated with the inflight separator FRS directly, or in combination with either the storage-cooler ring ESR or the FRS Ion Catcher. 1000 A·MeV 238U ions were used to create 60 new neutron-rich isotopes separated and identified with the FRS to measure their production cross sections. In another experimental campaign the fragments were separated in flight and injected into the storage-cooler ring ESR for accurate mass and lifetime measurements. In these experimentswe have obtained accurate new mass values analyzed via a novel method which has reduced the systematic errors for both Schottky Mass Spectrometry (SMS) and for Isochronous Mass Spectrometry (IMS). Pioneering experiments have been carried out with the FRS Ion Catcher consisting of three experimental components, the dispersive magnetic system of the FRS with a monoenergetic and a homogeneous degrader, a cryogenic stopping cell filled with pure helium and a multiple-reflection time-of flight mass separator. The FRS Ion Catcher enables high precision spectroscopy experiments with eV to keV exotic nuclides. Results from these different FRS experiments are presented in this overview together with prospects for the next-generation facility Super-FRS. The novel features of the Super-FRS compared with the present FRS will be discussed in addition.

    Given an experimental setup and a fixed number of measurements, how should one take data to optimally reconstruct the state of a quantum system? The problem of optimal experiment design (OED) for quantum state tomography was first broached by Kosut et al.[R. Kosut, I. Walmsley, and H. Rabitz, e-print arXiv:quant-ph/0411093 (2004)]. Here we provide efficient numerical algorithms for finding the optimal design, and analytic results for the case of 'minimal tomography'. We also introduce the average OED, which is independent of the state to be reconstructed, and the optimal design for tomography (ODT), which minimizes tomographic bias. Monte Carlo simulations confirm the utility of our results for qubits. Finally, we adapt our approach to deal with constrained techniques such as maximum-likelihood estimation. We find that these are less amenable to optimization than cruder reconstruction methods, such as linear inversion.

    Tanigaki, F.; Masuda, D.; Yano, S.; Fujimoto, N.; Kamigaichi, S.

    National Space Development Agency of Japan (NASDA) has been developing various experiment facilities to conduct space biology researches in KIBO (JEM). The Cell Biology Experiment Facility (CBEF) and the Clean Bench (CB) are installed into JEM Life Science Rack. The Biological Experiment Units (BEU) are operated in the CBEF and the CB for many kinds of experiments on cells, tissues, plants, microorganisms, or small animals. It is possible for all researchers to use these facilities under the system of the International Announcement of Opportunity. The CBEF is a CO2 incubator to provide a controlled environment (temperature, humidity, and CO2 concentration), in which a rotating table is equipped to make variable gravity (0-2g) for reference experiments. The containers called "Canisters" can be used to install the BEU in the CBEF. The CBEF supplies power, command, sensor, and video interfaces for the BEU through the utility connectors of Canisters. The BEU is a multiuser system consisting of chambers and control segments. It is operated by pre-set programs and by commands from the ground. NASDA is currently developing three types of the BEU: the Plant Experiment Unit (PEU) for plant life cycle observations and the Cell Experiment Unit (CEU1&2) for cell culture experiments. The PEU has an automated watering system with a water sensor, an LED matrix as a light source, and a CCD camera to observe the plant growth. The CEUs have culture chambers and an automated cultural medium exchange system. Engineering models of the PEU and CEU1 have been accomplished. The preliminary design of CEU2 is in progress. The design of the BEU will be modified to meet science requirements of each experiment. The CB provides a closed aseptic work-space (Operation Chamber) with gloves for experiment operations. Samples and the BEU can be manually handled in the CB. The CB has an air lock (Disinfection Chamber) to prevent contamination, and HEPA filters to make class-100-equivalent clean air

    Cloud resources promise to be an avenue to address new categories of scientific applications including data-intensive science applications, on-demand/surge computing, and applications that require customized software environments. However, there is a limited understanding on how to operate and use clouds for scientific applications. Magellan, a project funded through the Department of Energy?s (DOE) Advanced Scientific Computing Research (ASCR) program, is investigating the use of cloud computing for science at the Argonne Leadership Computing Facility (ALCF) and the National Energy Research Scientific Computing Facility (NERSC). In this paper, we detail the experiences to date at both sites and identify the gaps and open challenges from both a resource provider as well as application perspective.

    The Joint Science Education Project (JSEP), sponsored by the National Science Foundation, is a two-part program that brings together students and teachers from the United States, Greenland, and Denmark, for a unique cross-cultural, first-hand experience of the realities of polar science field research in Greenland. During JSEP, students experienced research being conducted on and near the Greenland ice sheet by attending researcher presentations, visiting NSF-funded field sites (including Summit and NEEM field stations, both located on the Greenland ice sheet), and designing and conducting research projects in international teams. The results of two of these projects will be highlighted. The atmospheric project investigated the differences in CO2, UVA, UVB, temperature, and albedo in different Arctic microenvironments, while also examining the interaction between the atmosphere and water present in the given environments. It was found that the carbon dioxide levels varied: glacial environments having the lowest levels, with an average concentration of 272.500 ppm, and non-vegetated, terrestrial environments having the highest, with an average concentration of 395.143 ppm. Following up on these results, it is planned to further investigate the interaction of the water and atmosphere, including water's role in the uptake of carbon dioxide. The ecology project investigated the occurrence of unusual large blooms of Nostoc cyanobacteria in Kangerlussuaq area lakes. The water chemistry of the lakes which contained the cyanobacteria and the lakes that did not were compared. The only noticeable difference was of the lakes' acidity, lakes containing the blooms had an average pH value of 8.58, whereas lakes without the blooms had an average pH value of 6.60. Further investigation of these results is needed to determine whether or not this was a cause or effect of the cyanobacteria blooms. As a next step, it is planned to attempt to grow the blooms to monitor their effects on

  18. Science experiences of six elementary student teachers: A case study

    NASA Astrophysics Data System (ADS)

    Willcox, Jacqueline Kay

    This qualitative study focused on the science experiences of six elementary student teachers. The purpose of the study was to learn how preservice teachers make meaning of science teaching during their student teaching experience. The sources of data were interviews with participants, descriptive field notes from observations of their science teaching, and artifacts collected from the site. The themes that emerged from data analysis were personal and professional career influences and constant adjustments of teaching strategies. The participants experienced these themes in varying intensities. Learning to teach science to elementary children for the first time is complicated by the context of student teaching. The science teaching experiences of student teachers varied with the cooperating teachers' approaches to science teaching, the lengths of time they were assigned to teach science, and the science schedules of the classroom. The role played by mentors interested in science can be important in a student teacher's science experience. Images of science teaching held by student teachers were also found to influence the science teaching experience. The science curriculum, group management skills, and student responses affected the science teaching experience, as did personal knowledge of a science topic being taught. Those student teachers who had limited knowledge of a science topic became factually oriented in their teaching and tried fewer teaching approaches. Lack of experience and management skills with cooperative groups hindered student teachers' use of hands on activities. Affective student responses to their science lessons were important to some of the student teachers, while others were concerned about student questions and cognitive learning. Upon completion of the student teaching experience, four of the participants ranked science third or lower in a rank order of subjects they enjoyed teaching during student teaching. At the end of their student

    The scientific objectives of the Giotto Radio Science Experiment (GRE) are to determine the columnar electron content of Comet Halley/s ionosphere and the cometary mass fluence from atmospheric drag by using the radio signals from Giotto during the Halley encounter. The radio science data (S and X-band Doppler and range measurements) will be collected at NASA/s deep-space 64 m tracking antenna at Tidbinbilla near Canberra, in Australia. In order to separate the effects of the terrestrial ionosphere and the interplanetary plasma, S-band Doppler measurements will also be taken at Tidbinbilla along the line-of-sight of Japan/s cometary probe Sakigake during the Giotto-Halley Encounter. The measurements of cometary electron content and mass fluence will be inverted to derive the spatial distribution of the electron and mass (dust and gas) density within Halley/s coma. The GRE is the only experiment on Giotto capable of measuring the low-energy (10 eV) electron bulk population of Halley/s ionosphere and the total cometary mass flow impacting upon the spacecraft.

  1. Research Experiences in Community College Science Programs

    2011-12-01

    The benefits of student access to scientific research opportunities and the use of data in curriculum and student inquiry-driven approaches to teaching as effective tools in science instruction are compelling (i.e., Ledley, et al., 2008; Gawel & Greengrove, 2005; Macdonald, et al., 2005; Harnik & Ross. 2003). Unfortunately, these experiences are traditionally limited at community colleges due to heavy faculty teaching loads, a focus on teaching over research, and scarce departmental funds. Without such hands-on learning activities, instructors may find it difficult to stimulate excitement about science in their students, who are typically non-major and nontraditional. I present two different approaches for effectively incorporating research into the community college setting that each rely on partnerships with other institutions. The first of these is a more traditional approach for providing research experiences to undergraduate students, though such experiences are limited at community colleges, and involves student interns working on a research project under the supervision of a faculty member. Specifically, students participate in a water quality assessment study of two local bayous. Students work on different aspects of the project, including water sample collection, bio-assay incubation experiments, water quality sample analysis, and collection and identification of phytoplankton. Over the past four years, nine community college students, as well as two undergraduate students and four graduate students from the local four-year university have participated in this research project. Aligning student and faculty research provides community college students with the unique opportunity to participate in the process of active science and contribute to "real" scientific research. Because students are working in a local watershed, these field experiences provide a valuable "place-based" educational opportunity. The second approach links cutting-edge oceanographic

    In many societies, the aging of the population is becoming a major problem. This raises difficult issues for ethics and public policy. On what is known as the fair innings view, it is not impermissible to give lower priority to policies that primarily benefit the elderly. Philosophers have tried to justify this view on various grounds. In this article, I look at a consequentialist, a fairness-based, and a contractarian justification. I argue that all of them have implausible implications and fail to correspond to our moral intuitions. I end by outlining a different kind of consequentialist justification that avoids those implications and corresponds better to our considered moral judgments. PMID:24909449

    2009-08-01

    The Air Force Research Laboratory, Space Vehicles Directorate (AFRL/RV) has developed the Demonstration and Science Experiments (DSX) mission to research technologies needed to significantly advance Department of Defense (DoD) capabilities to operate spacecraft in the harsh radiation environment of Medium-Earth Orbits (MEO). The ability to operate effectively in the MEO environment significantly increases the DoD's capability to field space systems that provide persistent global space surveillance and reconnaissance, high-speed satellite-based communication, lower-cost GPS navigation, and protection from space weather and environmental effects on a responsive satellite platform. The three DSX physics-based research/experiment areas are: 1. Wave Particle Interaction Experiment (WPIx): Researching the physics of Very-Low-Frequency (VLF) electromagnetic wave transmissions through the ionosphere and in the magnetosphere and characterizing the feasibility of natural and man-made VLF waves to reduce and precipitate space radiation; 2. Space Weather Experiment (SWx): Characterizing, mapping, and modeling the space radiation environment in MEO, an orbital regime attractive for future DoD, Civil, and Commercial missions; and 3. Space Environmental Effects (SFx): Researching and characterizing the MEO space weather effects on spacecraft electronics and materials. Collectively, thirteen individual payloads are combined together from these three research areas and integrated onto a single platform (DSX) which provides a low-cost opportunity for AFRL due to their common requirements. All three experiments require a 3-axis stabilized spacecraft bus (but no propulsion), a suite of radiation sensors, and extended duration in a low inclination, elliptical, MEO orbit. DSX will be launch-ready in summer 2010 for a likely launch comanifest with an operational DoD satellite on an Evolved Expendable Launch Vehicle (EELV).

    This paper presents an overview of the U.S. life sciences laboratory concepts envisioned for the Shuttle/Spacelab era. The basic development approach is to provide a general laboratory facility supplemented by specific experiment hardware as required. The laboratory concepts range from small carry-on laboratories to fully dedicated laboratories in the Spacelab pressurized module. The laboratories will encompass a broad spectrum of research in biology and biomedicine requiring a variety of research organisms. The environmental control and life support of these organisms is a very important aspect of the success of the space research missions. Engineering prototype organism habitats have been designed and fabricated to be compatible with the Spacelab environment and the experiment requirements. These first-generation habitat designs and their subsystems have supported plants, cells/tissues, invertebrates, and small vertebrates in limited evaluation tests. Special handling and transport equipment required for the ground movement of the experiment organisms at the launch/landing site have been built and tested using these initial habitat prototypes.

    The Life Sciences Flight Experiments Program (LSFEP) was established by NASA in 1978 to plan and direct efforts necessary to conduct a continuing program of in-flight life science investigations throughout the Space Shuttle era. The Spacelab 1 (SL-1) mission, conducted from November 28 to December 8, 1983, was to verify Spacelab performance through a variety of scientific experiments including life science. A description is given of the seven NASA life sciences experiments, which consisted of four human experiments, a fungus experiment, a plant experiment, and radiation experiments. Ten life sciences experiments from the European Space Agency were also flown. The experiments include studies of the circadian rhythms in Neurospora crassa, the nutation of Helianthus annus, the vestibular function during weightlessness, the influence of space flight on erythrokinetics in man, and the adaptation of vestibulo-spinal reflex mechanisms during space flight.

Several key themes emerged from focus group discussions: learning to become research scientists, experiences with the culture of science, and views on racial and social stigma. Participants spoke of essential factors for becoming a scientist, but their experiences also raised complex issues about the role of race and social stigma in scientific training. Students experienced the collaborative and empowering culture of science, exhibited strong science identities and high self-efficacy, while developing directed career goals as a result of “doing science” in these programs.

    The New Horizons (NH) Radio Science Experiment, REX, is designed to determine the atmospheric state at the surface of Pluto and in the lowest few scale heights. Expected absolute accuracies in n, p, and T at the surface are 4ṡ1019 m-3, 0.1 Pa, and 3 K, respectively, obtained by radio occultation of a 4.2 cm- λ signal transmitted from Earth at 10-30 kW and received at the NH spacecraft. The threshold for ionospheric observations is roughly 2ṡ109 e- m-3. Radio occultation experiments are planned for both Pluto and Charon, but the level of accuracy for the neutral gas is expected to be useful at Pluto only. REX will also measure the nightside 4.2 cm- λ thermal emission from Pluto and Charon during the time NH is occulted. At Pluto, the thermal scan provides about five half-beams across the disk; at Charon, only disk integrated values can be obtained. A combination of two-way tracking and occultation signals will determine the Pluto system mass to about 0.01 percent, and improve the Pluto-Charon mass ratio. REX flight equipment augments the NH radio transceiver used for spacecraft communications and tracking. Implementation of REX required realization of a new CIC-SCIC signal processing algorithm; the REX hardware implementation requires 1.6 W, and has mass of 160 g in 520 cm3. Commissioning tests conducted after NH launch demonstrate that the REX system is operating as expected.

    1997-07-01

    The Mars Horizon Sensor Assembly on the MGS orbiter monitors the orientation of the spacecraft relative to the limb by sensing atmospheric emission in the 15 mu m CO2 band. These data are used to maintain nadir pointing for the remote sensing instrument suite. The set of 5.5deg tall triangular fields of view normally straddle the limb, and cover quadrants 90deg apart around the limb. As an engineering device, the MHSA benefits from Mars' atmosphere being spatially bland at 15 mu m. However, these data will carry information about the thermal state of the atmosphere, which is subject to diurnal, seasonal, latitudinal, and dust-storm related variations, as well as possible wave effects. The Mariner 7 IRS, Mariner 9 IRIS, and Viking IRTM all demonstrated such variability. The Horizon Science Experiment (HORSE) is intended to glean new insight into atmospheric variation from the MGS horizon sensors, with continuous data flow to the Earth in the engineering stream, and a rapid buildup of spatial coverage. MHSA data will also be used to monitor atmospheric thermal behavior during the aerobraking of MGS in late 1997.

    2009-01-01

    Priority setting in health care under conventional rules of health economic evaluation is based upon the ethos of attempting to maximize post-treatment health gain given available health care resources. In his later years, Alan Williams advocated the "fair innings argument,'' which balances differences in whole lifetime experiences of health with differences in post-treatment outcomes when prioritizing people for health care. This article reports a study that presented respondents with a number of abstract health care decision contexts in an attempt to test the extent to which post-treatment health maximization, the fair innings argument, or, indeed other "decision rules,'' are evident in the respondents' answers. The results indicate that the most commonly observed decision rule differs substantially across health care contexts, and therefore imply that rather than pursue an overarching decision rule, it may be more appropriate to vary the rule according to the particular health care decision context under consideration.

    Minger, Mark Austin

    Having fears and frustrations while studying science topics can lead to science anxiety for some individuals. For those who experience science learning anxiety, the reality is often poor performance, lowered self-esteem, anger, and avoidance of further science courses. Using an interpretive approach, this study captures the experiences of five self-reported science anxious students as they participate in an interdisciplinary science course at the University of Minnesota. A series of three in-depth interviews were conducted with five students who were enrolled in the "Our Changing Planet" course offered at the University of Minnesota. The interviews were transcribed verbatim, coded, and analyzed thematically. Four major themes emerged from the interviews. Two of the themes involve the realities of being a science anxious student. These focus on participants' experiences of feeling frustrated, anxious and incompetent when studying both math and science; and the experiences of trying to learn science content that does not seem relevant to them. The last two themes highlight the participants' perceptions of their experiences during the "Our Changing Planet" course, including how the course seemed different from previous science courses as well as their learning experiences in cooperative groups. After presenting the themes, with supporting quotations, each theme is linked to the related literature. The essence of the participants' science anxiety experiences is presented and practical implications regarding science anxious students are discussed. Finally, insights gained and suggestions for further research are provided.

    Guisao, Victor, Jr.

    This study observed and analyzed how students with Cooperative Inquiry Performance Method(c) (CIPM(c)) experience presented and defended their science fair projects. CIPM(c) is a teaching and learning strategy which connects many learning theories into a package starting with group building activities (group norms and roles) to group inquiry-based lessons and experiments leading to a presentation and defense of the group's findings and the methodology used in forming their conclusions. The study also examined the types of questions and answers elicited from students with CIPM(c) experience and how these students demonstrated knowledge about the "process" of their research as evidenced in their project presentation and defense. The study took place in an urban junior high school in Brooklyn, New York. This population, on a whole, received training in CIPM(c) strategies from the same teacher for six months. Observations of 38 groups of seventh graders with 3 to 4 students composing each group was conducted. There was follow-up interviewing of four randomly selected groups. Both class presentations and interviews were videotaped. The results revealed the following about students with CIPM(c) experience: (1) 92% (35 of 38) of all groups had all members present a portion of the project; (2) both empirical (recall) and analytical (process) questions were asked during both the oral presentation of the project and the question and answer session; (3) 82% (31 of 38) of all groups presented their projects through (a) a step-by-step method of investigation or (b) a series of questions; (4) students collaborated in developing not only the idea and questions but the results which they presented; (5) students designed their project investigations around a central theme: "Life in the 21st Century;" (6) 58% (22 of 38) of all groups had more than one student answer questions during the question and answer session; However, results revealed certain weaknesses in the group project

    2010-12-01

    Understanding preservice teachers' memories of their education may aid towards articulating high-impact teaching practices. This study describes 246 preservice teachers' perceptions of their secondary science education experiences through a questionnaire and 28-item survey. ANOVA was statistically significant about participants' memories of science with 15 of the 28 survey items. Descriptive statistics through SPSS further showed that a teacher's enthusiastic nature (87%) and positive attitude towards science (87%) were regarded as highly memorable. In addition, explaining abstract concepts well (79%), and guiding the students' conceptual development with practical science activities (73%) may be considered as memorable secondary science teaching strategies. Implementing science lessons with one or more of these memorable science teaching practices may "make a difference" towards influencing high school students' positive long-term memories about science and their science education.

  12. Science identity construction through extraordinary professional development experiences

    NASA Astrophysics Data System (ADS)

    McLain, Bradley David

    Despite great efforts and expenditures to promote science literacy and STEM career choices, the U.S. continues to lag behind other countries in science education, diminishing our capacity for STEM leadership and our ability to make informed decisions in the face of multiple looming global issues. I suggest that positive science identity construction (the integration of science into one's sense of self so that it becomes a source of inspiration and contributes to lifelong learning) is critical for promoting durable science literacy and pro-science choices. Therefore, the focus of this study was extraordinary professional development experiences for science educators that may significantly impact their sense of self. My hypothesis was that such experiences could positively impact educators' science and science educator identities, and potentially enhance their capacities to impact student science identities. The first part of this hypothesis is examined in this study. Further, I suggest that first-person narratives play an important role in science identity construction. Presenting a new conceptual model that connects experiential learning theory to identity theory through the narrative study of lives, I explored the impacts of subjectively regarded extraordinary professional development experiences on the science identity and science educator identity construction processes for a cohort of fifteen K-12 science teachers during a science-learning-journey to explore the volcanoes of Hawaii. I used a case study research approach under the broader umbrella of a hermeneutic phenomenology to consider four individual cases as lived experiences and to consider the journey as a phenomenon unto itself. Findings suggest science and science educator identities are impacted by such an experience but with marked variability in magnitude and nature. Evidence also suggests important impacts on their other identities. In most instances, science-related impacts were secondary to and

  13. Changes in Urban Youths' Attitude Towards Science and Perception of a Mobile Science Lab Experience

    NASA Astrophysics Data System (ADS)

    Fox, Jared

    This dissertation examined changes in urban youth's attitude towards science as well as their perception of the informal science education setting and third space opportunity provided by the BioBus, a mobile science lab. Science education researchers have often suggested that informal science education settings provide one possible way to positively influence student attitude towards science and engage marginalized urban youth within the traditional science classroom (Banks et al., 2007; Hofstein & Rosenfeld, 1996; National Research Council, 2009; Schwarz & Stolow, 2006; Stocklmayer, Rennie, & Gilbert, 2010). However, until now, this possibility has not been explored within the setting of a mobile science lab nor examined using a theoretical framework intent on analyzing how affective outcomes may occur. The merits of this analytical stance were evaluated via observation, attitudinal survey, open-response questionnaire, and interview data collected before and after a mobile science lab experience from a combination of 239 students in Grades 6, 8, 9, 11, and 12 from four different schools within a major Northeastern metropolitan area. Findings from this study suggested that urban youth's attitude towards science changed both positively and negatively in statistically significant ways after a BioBus visit and that the experience itself was highly enjoyable. Furthermore, implications for how to construct a third space within the urban science classroom and the merits of utilizing the theoretical framework developed to analyze cultural tensions between urban youth and school science are discussed. Key Words: Attitude towards science, third space, mobile science lab, urban science education.

  15. Teacher research experiences, epistemology, and student attitudes toward science

    NASA Astrophysics Data System (ADS)

    Payne, Diana L.

    This concurrent mixed methods research study examined the impact of a Teacher Research Experience (TRE) on science teacher beliefs about science, scientific research, science teaching, and student attitudes toward science. Surveys, interviews, reflective journals, and classroom observations of six teachers involved in a TRE were utilized to examine changes in beliefs as a result of participation in the TRE. Student attitudes were measured with a pre and post survey. An analysis of qualitative data from the teachers' interviews, journals, and pre and post TRE surveys indicated that some change occurred in their beliefs about science and scientists for all six teachers, and that teachers' beliefs about science teaching were affected in a variety of ways after participating in the TRE. The quantitative results of the study using Science Teachers' Beliefs About Science (STBAS) instrument suggest that the change from the beginning to the end of the school year, if any, was minimal. However, interviews with and observations of teachers identified valuable components of the TRE, such as the advanced resources (e.g., DVD, samples), a feeling of rejuvenation in teaching, a new perspective on science and scientific research, and first hand experiences in science. Results from the classroom observations using the Science Classroom Practice Record (SCPR) were mixed. Some differences may be explained, however, as relating to content taught in the pre and post classes observed or simply to inherent differences in student dynamics and behavior from class to class. There were no significant differences from pre to post TRE regarding student attitudes toward science as measured by paired samples t-tests on the modified Attitudes Toward Science (mATSI) instrument. Attitudes and beliefs are not easily changed, and change is more likely to result from direct experience and education rather than an indirect experience. Although the results are generalizable only to the participants in

    2009-09-01

    We report on the accomplishments of the HiRISE EPO program over the last two and a half years of science operations. We have focused primarily on delivering high impact science opportunities through our various participatory science and citizen science websites. Uniquely, we have invited students from around the world to become virtual HiRISE team members by submitting target suggestions via our HiRISE Quest Image challenges using HiWeb the team's image suggestion facility web tools. When images are acquired, students analyze their returned images, write a report and work with a HiRISE team member to write a image caption for release on the HiRISE website (http://hirise.lpl.arizona.edu). Another E/PO highlight has been our citizen scientist effort, HiRISE Clickworkers (http://clickworkers.arc.nasa.gov/hirise). Clickworkers enlists volunteers to identify geologic features (e.g., dunes, craters, wind streaks, gullies, etc.) in the HiRISE images and help generate searchable image databases. In addition, the large image sizes and incredible spatial resolution of the HiRISE camera can tax the capabilities of the most capable computers, so we have also focused on enabling typical users to browse, pan and zoom the HiRISE images using our HiRISE online image viewer (http://marsoweb.nas.nasa.gov/HiRISE/hirise_images/). Our educational materials available on the HiRISE EPO web site (http://hirise.seti.org/epo) include an assortment of K through college level, standards-based activity books, a K through 3 coloring/story book, a middle school level comic book, and several interactive educational games, including Mars jigsaw puzzles, crosswords, word searches and flash cards.

    The Mission Science Requirements Document (MSRD) for the First Dedicated Life Sciences Mission (LS-1) represents the culmination of thousands of hours of experiment selection, and science requirement definition activities. NASA life sciences has never before attempted to integrate, both scientifically and operationally, a single mission dedicated to life sciences research, and the complexity of the planning required for such an endeavor should be apparent. This set of requirements completes the first phase of a continual process which will attempt to optimize (within available programmatic and mission resources) the science accomplished on this mission.

  1. Connecting science to everyday experiences in preschool settings

    NASA Astrophysics Data System (ADS)

    Roychoudhury, Anita

    2014-06-01

    In this paper I discuss the challenges of teaching science concepts and discourse in preschool in light of the study conducted by Kristina Andersson and Annica Gullberg. I then suggest a complementary approach to teaching science at this level from the perspective of social construction of knowledge based on Vygotsky's theory (1934/1987). In addition, I highlight the importance of the relational aspect of knowing using feminist standpoint theory (Harding 2004). I also draw from feminist research on preservice elementary teachers' learning of science to further underscore the connection between learning content and everyday experiences. Combining these research strands I propose that science needs to be grounded in everyday experiences. In this regard, the idea is similar to the choices made by the teachers in the study conducted by Andersson and Gullberg but I also suggest that the everyday experiences chosen for teaching purposes be framed appropriately. In and of itself, the complexity of everyday experiences can be impediment for learning as these researchers have demonstrated. Such complexities point to the need for framing of everyday experiences (Goffman 1974) so that children can do science and construct meaning from their actions. In the conclusion of my discussion of science and its discourse in preschool settings, I provide examples of everyday experiences and their framings that have the potential for engaging children and their teachers in science.

  2. Children develop a veil of fairness.

    PubMed

    Shaw, Alex; Montinari, Natalia; Piovesan, Marco; Olson, Kristina R; Gino, Francesca; Norton, Michael I

    2014-02-01

    Previous research suggests that children develop an increasing concern with fairness over the course of development. Research with adults suggests that the concern with fairness has at least 2 distinct components: a desire to be fair and a desire to signal to others that they are fair. We explore whether children's developing concern with behaving fairly toward others may in part reflect a developing concern with appearing fair to others. In Experiments 1 and 2, most 6- to 8-year-old children behaved fairly toward others when an experimenter was aware of their choices; fewer children opted to behave fairly, however, when they could be unfair to others yet appear fair to the experimenter. In Experiment 3, we explored the development of this concern with appearing fair by using a wider age range (6- to 11-year-olds) and a different method. In this experiment, children chose how to assign a good or bad prize to themselves and another participant by either unilaterally deciding who would get each prize or using a fair procedure--flipping a coin in private. Older children were much more likely to flip the coin than younger children, yet were just as likely as younger children to assign themselves the good prize by reporting winning the coin flip more than chance would dictate. Overall, the results of these experiments suggest that as children grow older they become increasingly concerned with appearing fair to others, which may explain some of their increased tendency to behave fairly.

  15. Do information, price, or morals influence ethical consumption? A natural field experiment and customer survey on the purchase of Fair Trade coffee.

    PubMed

    Andorfer, Veronika A; Liebe, Ulf

    2015-07-01

    We address ethical consumption using a natural field experiment on the actual purchase of Fair Trade (FT) coffee in three supermarkets in Germany. Based on a quasi-experimental before-and-after design the effects of three different treatments - information, 20% price reduction, and a moral appeal - are analyzed. Sales data cover actual ethical purchase behavior and avoid problems of social desirability. But they offer only limited insights into the motivations of individual consumers. We therefore complemented the field experiment with a customer survey that allows us to contrast observed (ethical) buying behavior with self-reported FT consumption. Results from the experiment suggest that only the price reduction had the expected positive and statistically significant effect on FT consumption. PMID:26004466

  17. Field experiences in science teacher preparation programs of Missouri

    NASA Astrophysics Data System (ADS)

    Rhea, Marilyn Sue Alvis

    The purpose of this study was to collect and analyze data pertinent to identifying the differences and similarities in the design and implementation of field experiences for pre-service science teachers in institutions of higher education in the State of Missouri. Directors of field experience from 25 Institutions of Higher Education (IHE) that prepare both elementary and secondary science teachers and 5 additional IHE that prepare only elementary teachers were surveyed using a 48-item Likert scale instrument designed for this study. Data were collected on the hours of field experience in relation to science and other methods classes, distribution of field experience hours across the program, and total hours of field experience required. Comparisons were made between elementary and secondary science teacher preparation programs. Five areas of field experience were surveyed: design of early field experience, design of student teaching, support provided by IHE for cooperating schools, field experience assessment practices, and relationships between pre-service teachers, cooperating teachers and IHE educators. Analyses of the responses indicate statistically significant differences in the number of field experience hours between IRE programs for both early field experience (p < .05) and student teaching (p < .01). Differences in number of field experience hours by level of certification were not significant. Correlation of scores was significant between the elementary and secondary levels for both early field experience design (r = .97) and student teaching design (r = .75). No other significant correlation was found. This study found highly heterogeneous practices regarding field experience exist in Missouri IHE programs. When reported practices are compared to standards set in the professional literature, as a group Missouri IHE science teacher preparation programs could be described as traditional apprenticeships or quasi-professional development school programs.

  18. Preservice science teachers' experiences with repeated, guided inquiry

    NASA Astrophysics Data System (ADS)

    Slack, Amy B.

    The purpose of this study was to examine preservice science teachers' experiences with repeated scientific inquiry (SI) activities. The National Science Education Standards (National Research Council, 1996) stress students should understand and possess the abilities to do SI. For students to meet these standards, science teachers must understand and be able to perform SI; however, previous research demonstrated that many teachers have naive understandings in this area. Teacher preparation programs provide an opportunity to facilitate the development of inquiry understandings and abilities. In this study, preservice science teachers had experiences with two inquiry activities that were repeated three times each. The research questions for this study were (a) How do preservice science teachers' describe their experiences with repeated, guided inquiry activities? (b) What are preservice science teachers' understandings and abilities of SI? This study was conducted at a large, urban university in the southeastern United States. The 5 participants had bachelor's degrees in science and were enrolled in a graduate science education methods course. The researcher was one of the course instructors but did not lead the activities. Case study methodology was used. Data was collected from a demographic survey, an open-ended questionnaire with follow-up interviews, the researcher's observations, participants' lab notes, personal interviews, and participants' journals. Data were coded and analyzed through chronological data matrices to identify patterns in participants' experiences. The five domains identified in this study were understandings of SI, abilities to conduct SI, personal feelings about the experience, science content knowledge, and classroom implications. Through analysis of themes identified within each domain, the four conclusions made about these preservice teachers' experiences with SI were that the experience increased their abilities to conduct inquiry

  19. Interest enhancements to science experiments: Interactions with student gender

    NASA Astrophysics Data System (ADS)

    Martinez, Michael E.

    Males are more likely than females to aspire to and enter scientific careers, a pattern that might be attributed to gender differences in the appeal of school science. Differences might arise, in part, from gender-related interactions with the interest value of school science experiments. If modifiable, the interest value of experiments could influence attitudes toward science and subsequent choices concerning science involvement. In this study, middle school students carried out versions of science experiments designed to vary in their interest value. Experiment modifications, guided by a three-component model of interest, ranged from introduction of fantasy scenarios to manipulation of the difficulty and social context of the experiments. Subjects were 101 middle school students, 46 males and 55 females. Of primary interest were MANOVA comparisons of self-reported interest in the experiments, by gender and experimental condition. In general, interest enhancements were more effective for girls than boys. Boys were more attentive to aspects of the experiments that elicit perceptions of control, whereas girls were more attentive to social aspects.

  20. Pre-college Science Experiences; Timing and Causes of Gender Influence Science Interest Levels

    NASA Astrophysics Data System (ADS)

    Kaplita, E.; Reed, D. E.; McKenzie, D. A.; Jones, R.; May, L. W.

    2015-12-01

    It is known that female students tend to turn away from science during their pre-college years. Experiences during this time are not limited to the classroom, as cultural influences extend beyond K-12 science education and lead to the widely studied reduction in females in STEM fields. This has a large impact on climate science because currently relatively little effort is put into K-12 climate education, yet this is when college attitudes towards science are formed. To help quantify these changes, 400 surveys were collected from 4 different colleges in Oklahoma. Student responses were compared by gender against student experiences (positive and negative), and interest in science. Results of our work show that females tend to have their first positive experience with science at a younger age with friends, family and in the classroom, and have more of an interest in science when they are younger. Males in general like experiencing science more on their own, and surpass the interest levels of females late in high school and during college. While in college, males are more comfortable with science content than females, and males enjoy math and statistics more while those aspects of science were the largest areas of dislike in females. Understanding how to keep students (particularly female) interested in science as they enter their teen years is extremely important in preventing climate misconceptions in the adult population. Potential small changes such as hosting K-12 climate outreach events and including parents, as opposed to just inviting students, could greatly improve student experiences with science and hence, their understanding of climate science. Importantly, a greater focus on female students is warranted.

    2006-12-01

    The decision to study physics or astronomy is affected by many factors, including preferences, motivations, and expectations for success. Differing cognitive profiles contribute to the learning of science through a complex process in which intrinsic capacities are tuned both by everyday experience and by instruction. In an attempt to identify the developmental pathways and intrinsic factors that most strongly influence the choice to study science, we administered an extensive survey to a sample of 400 students. The survey questions were based on Eccles et al.’s model of achievement-related choices and findings showing that previous play experiences, spatial experiences, task beliefs, as well as perceived mathematics ability, motivational and personality characteristics affect mathematics achievement and science career choices. The perceptions of students planning a science career are compared with those planning a career in other areas. Gender differences are also discussed.

  3. Science Experiences among Female Athletes: Race Makes a Difference

    NASA Astrophysics Data System (ADS)

    Kraus, Rebecca S.; Hanson, Sandra L.

    Sport participation is increasingly seen as a resource with considerable physical, social, and academic benefits. As a new millennium begins with girls more visible in sport, an important question is whether all girls reap these benefits. Although general academic benefits of sport have been shown, the authors' earlier work showed that experience in the male sport domain benefits young women in the elite (often male) science curriculum. Competition, self-esteem, and other individual resources gained through sport are potential sources of success in the similarly competitive male realm of science. In this research, the authors used critical feminist theory to guide their examination of racial and ethnic variations in the relation between sport participation and science experiences for young women. Data from the nationally representative National Education Longitudinal Study were used to explore the impact of sport participation in the 8th and 10th grades on 10th grade science achievement (measured by science grades and standardized test scores) and course taking for African American, Hispanic, and White women. The findings revealed that sport participation has some positive consequences for the science experiences of each of the groups of women. It also has some negative consequences, although the positive consequences outnumber the negative consequences for Hispanic and White, but not African American, women. Sport in 10th grade, especially competitive varsity sport, is most likely to have positive consequences. The findings revealed that each of the groups experiences different routes to success in science, and sport participation is present at some level in each of these routes. A consideration of multiple areas of science experience is important for understanding the connections between race and ethnicity, sport, and science for young women. Unique sociocultural contexts are used to attempt to understand these findings, and implications are discussed.

    Proton radiography was invented in the 1990's at Los Alamos National Laboratory (LANL) as a diagnostic to study dynamic material properties under extreme pressures, strain and strain rate. Since this time hundreds of dynamic proton radiography experiments have been performed at LANL and a facility has been commissioned at the Institute for Theoretical and Experimental Physics (ITEP) in Russia for similar applications in dynamic material studies. Recently an international effort has investigated a new proton radiography capability for the study of dynamic material properties at the Facility for Anti-proton and Ion Research (FAIR) located in Darmstadt, Germany. This new Proton microscope for FAIR(PRIOR) will provide radiographic imaging of dynamic systems with unprecedented spatial, temporal and density resolution, resulting in a window for understanding dynamic material properties at new length scales. It is also proposed to install the PRIOR system at the GSI Helmholtzzentrum fuer Schwerionenforschung before installation at FAIR for dynamic experiments with different drivers including high explosives, pulsed power and lasers. The design of the proton microscope and expected radiographic performance is presented.

  7. Research Experiences for Science Teachers: The Impact On Their Students

    Deficiencies in science preparedness of United States high school students were recognized more than two decades ago, as were some of their underlying causes. Among the primary causes are the remoteness of the language, tools, and concepts of science from the daily experiences of teachers and students, and the long-standing national shortage of appropriately prepared science teachers. Secondary school science teachers are challenged each school year by constantly changing content, new technologies, and increasing demands for standards-based instruction. A major deficiency in the education of science teachers was their lack of experience with the practice of science, and with practicing scientists. Providing teachers with opportunities to gain hands-on experience with the tools and materials of science under the guidance and mentorship of leading scientists in an environment attuned to professional development, would have many beneficial effects. They would improve teachers' understanding of science and their ability to develop and lead inquiry- and standards-based science classes and laboratories. They would enable them to communicate the vitality and dynamism of science to their students and to other teachers. They would enhance their ability to motivate and guide students. From its inception, Columbia University's Summer Research Program for Science Teacher's goal has been to enhance interest and improve performance in science of students in New York City area schools. The program seeks to achieve this goal by increasing the professional competence of teachers. Our ongoing program evaluation shows that following completion of the program, the teachers implement more inquiry-based classroom and laboratory exercises, increase utilization of Internet resources, motivate students to participate in after school science clubs and Intel-type science projects; and create opportunities for students to investigate an area of science in greater depth and for longer periods

  9. Questions of fairness and anti-doping in US cycling: The contrasting experiences of professionals and amateurs

    PubMed Central

    Henning, April D.; Dimeo, Paul

    2015-01-01

    Abstract The focus of researchers, media and policy on doping in cycling is often limited to the professional level of the sport. However, anti-doping test results since 2001 demonstrate that banned substances are also used by US cyclists at lower levels of the sport, necessitating a broader view of the patterns and motivations of substance use within the sport. In this article, we describe and explain the doping culture that has emerged in domestic US cycling among amateur and semi-professionals. Through analysis of records from sports governing bodies and journalistic reports, we assess the range of violation types and discuss the detection and punishing of riders who were not proven to have intended to cheat but became “collateral damage” in the war on doping. We argue that the phenomenon of doping is more complex than what has been shown to occur in elite sport, as it includes a wider variety of behaviours, situations and motivations. We develop fresh insights by examining cases where doping has been accidental, intrinsically motivated, non-performance enhancing or the result of prescribed medical treatments banned by anti-doping authorities. Such trends call into question the fairness of anti-doping measures, and we discuss the possibility of developing localised solutions to testing and sanctioning amateur athletes. PMID:26692658

  14. Experience our Planet - Interpreting Earth Sciences in a Museum Environment

    NASA Astrophysics Data System (ADS)

    Schneider, S.

    2012-12-01

    Earth science interpretation is more than giving your audience facts and figures. It is about relating Earth sciences to something within the personality or experience of your audience. It is about revelation based on information rather than just giving away information per se. And: The chief aim of interpretation is not instruction but provocation. A great environment for Earth science interpretation is a museum. Whether it is an art gallery, a technology exhibition or a national park's visitor center is irrelevant. Earth science interpretation is possible everywhere and sometimes even more successful in unsuspected locations than in natural history museums. Earth sciences have just started to use the potential which lies within museum environments. A historic view on Earth sciences and natural hazard research can be given in art galleries. The technology used in research can be showcased and - sometimes - even tested in science centers and technology museums. National Parks provide the best opportunity to actually experience the dynamic planet Earth live. This talk aims towards giving an insight view on how to conduct interpretive programs in museums, how to utilize the treasures and possibilities provided by museums and national parks and to encourage scientists to go to these places for face-to-face Earth science interpretation.

  15. Experiences & Tools from Modeling Instruction Applied to Earth Sciences

    NASA Astrophysics Data System (ADS)

    Cervenec, J.; Landis, C. E.

    2012-12-01

    The Framework for K-12 Science Education calls for stronger curricular connections within the sciences, greater depth in understanding, and tasks higher on Bloom's Taxonomy. Understanding atmospheric sciences draws on core knowledge traditionally taught in physics, chemistry, and in some cases, biology. If this core knowledge is not conceptually sound, well retained, and transferable to new settings, understanding the causes and consequences of climate changes become a task in memorizing seemingly disparate facts to a student. Fortunately, experiences and conceptual tools have been developed and refined in the nationwide network of Physics Modeling and Chemistry Modeling teachers to build necessary understanding of conservation of mass, conservation of energy, particulate nature of matter, kinetic molecular theory, and particle model of light. Context-rich experiences are first introduced for students to construct an understanding of these principles and then conceptual tools are deployed for students to resolve misconceptions and deepen their understanding. Using these experiences and conceptual tools takes an investment of instructional time, teacher training, and in some cases, re-envisioning the format of a science classroom. There are few financial barriers to implementation and students gain a greater understanding of the nature of science by going through successive cycles of investigation and refinement of their thinking. This presentation shows how these experiences and tools could be used in an Earth Science course to support students developing conceptually rich understanding of the atmosphere and connections happening within.

  18. Citizen Science Practices for Computational Social Science Research: The Conceptualization of Pop-Up Experiments

    NASA Astrophysics Data System (ADS)

    Sagarra, Oleguer; Gutierrez-Roig, Mario; Bonhoure, Isabelle; Perelló, Josep

    2015-12-01

    Under the name of Citizen Science, many innovative practices in which volunteers partner up with scientists to pose and answer real-world questions are growing rapidly worldwide. Citizen Science can furnish ready-made solutions with citizens playing an active role. However, this framework is still far from being well established as a standard tool for computational social science research. Here, we present our experience in bridging gap between computational social science and the philosophy underlying Citizen Science, which in our case has taken the form of what we call ``pop-up experiments." These are non-permanent, highly participatory collective experiments which blend features developed by big data methodologies and behavioural experimental protocols with the ideals of Citizen Science. The main issues to take into account whenever planning experiments of this type are classified, discussed and grouped into three categories: infrastructure, public engagement, and the knowledge return for citizens. We explain the solutions we have implemented, providing practical examples grounded in our own experience in an urban context (Barcelona, Spain). Our aim here is that this work will serve as a guideline for groups willing to adopt and expand such in-vivo practices and we hope it opens up the debate regarding the possibilities (and also the limitations) that the Citizen Science framework can offer the study of social phenomena.

  19. An experiment on prediction markets in science.

    Almenberg, Johan; Kittlitz, Ken; Pfeiffer, Thomas

    2009-01-01

    Prediction markets are powerful forecasting tools. They have the potential to aggregate private information, to generate and disseminate a consensus among the market participants, and to provide incentives for information acquisition. These market functionalities can be very valuable for scientific research. Here, we report an experiment that examines the compatibility of prediction markets with the current practice of scientific publication. We investigated three settings. In the first setting, different pieces of information were disclosed to the public during the experiment. In the second setting, participants received private information. In the third setting, each piece of information was private at first, but was subsequently disclosed to the public. An automated, subsidizing market maker provided additional incentives for trading and mitigated liquidity problems. We find that the third setting combines the advantages of the first and second settings. Market performance was as good as in the setting with public information, and better than in the setting with private information. In contrast to the first setting, participants could benefit from information advantages. Thus the publication of information does not detract from the functionality of prediction markets. We conclude that for integrating prediction markets into the practice of scientific research it is of advantage to use subsidizing market makers, and to keep markets aligned with current publication practice.

    2007-01-01

    The present study examined the reliability of student evaluations of summer undergraduate research experiences using the SURE (Survey of Undergraduate Research Experiences) and a follow-up survey disseminated 9 mo later. The survey further examines the hypothesis that undergraduate research enhances the educational experience of science undergraduates, attracts and retains talented students to careers in science, and acts as a pathway for minority students into science careers. Undergraduates participated in an online survey on the benefits of undergraduate research experiences. Participants indicated gains on 20 potential benefits and reported on career plans. Most of the participants began or continued to plan for postgraduate education in the sciences. A small group of students who discontinued their plans for postgraduate science education reported significantly lower gains than continuing students. Women and men reported similar levels of benefits and similar patterns of career plans. Undergraduate researchers from underrepresented groups reported higher learning gains than comparison students. The results replicated previously reported data from this survey. The follow-up survey indicated that students reported gains in independence, intrinsic motivation to learn, and active participation in courses taken after the summer undergraduate research experience.

  7. Academic attainment and the high school science experiences among high-achieving African American males

    NASA Astrophysics Data System (ADS)

    Trice, Rodney Nathaniel

    This study examines the educational experiences of high achieving African American males. More specifically, it analyzes the influences on their successful navigation through high school science. Through a series of interviews, observations, questionnaires, science portfolios, and review of existing data the researcher attempted to obtain a deeper understanding of high achieving African American males and their limitations to academic attainment and high school science experiences. The investigation is limited to ten high achieving African American male science students at Woodcrest High School. Woodcrest is situated at the cross section of a suburban and rural community located in the southeastern section of the United States. Although this investigation involves African American males, all of whom are successful in school, its findings should not be generalized to this nor any other group of students. The research question that guided this study is: What are the limitations to academic attainment and the high school science experiences of high achieving African American males? The student participants expose how suspension and expulsion, special education placement, academic tracking, science instruction, and teacher expectation influence academic achievement. The role parents play, student self-concept, peer relationships, and student learning styles are also analyzed. The anthology of data rendered three overarching themes: (1) unequal access to education, (2) maintenance of unfair educational structures, and (3) authentic characterizations of African American males. Often the policies and practices set in place by school officials aid in creating hurdles to academic achievement. These policies and practices are often formed without meaningful consideration of the unintended consequences that may affect different student populations, particularly the most vulnerable. The findings from this study expose that high achieving African American males face major

    The decomposition of water by electricity, and the voltaic pile as a means of generating electricity, have both held an iconic status in the history of science as well as in the history of science teaching. These experiments featured in chemistry and physics textbooks, as well as in classroom teaching, throughout the nineteenth and twentieth centuries. This paper deals with our experiences in restaging the decomposition of water as part of a history of science course at the Norwegian University of Science and Technology, Trondheim, Norway. For the experiment we used an apparatus from our historical teaching collection and built a replica of a voltaic pile. We also traced the uses and meanings of decomposition of water within science and science teaching in schools and higher education in local institutions. Building the pile, and carrying out the experiments, held a few surprises that we did not anticipate through our study of written sources. The exercise gave us valuable insight into the nature of the devices and the experiment, and our students appreciated an experience of a different kind in a history of science course.

  14. Architecting Learning Continuities for Families Across Informal Science Experiences

    NASA Astrophysics Data System (ADS)

    Perin, Suzanne Marie

    By first recognizing the valuable social and scientific practices taking place within families as they learn science together across multiple, everyday settings, this dissertation addresses questions of how to design and scaffold activities that build and expand on those practices to foster a deep understanding of science, and how the aesthetic experience of learning science builds connections across educational settings. Families were invited to visit a natural history museum, an aquarium, and a place or activity of the family's choice that they associated with science learning. Some families were asked to use a set of activities during their study visits based on the practices of science (National Research Council, 2012), which were delivered via smartphone app or on paper cards. I use design-based research, video data analysis and interaction analysis to examine how families build connections between informal science learning settings. Chapter 2 outlines the research-based design process of creating activities for families that fostered connections across multiple learning settings, regardless of the topical content of those settings. Implications of this study point to means for linking everyday family social practices such as questioning, observing, and disagreeing to the practices of science through activities that are not site-specific. The next paper delves into aesthetic experience of science learning, and I use video interaction analysis and linguistic analysis to show how notions of beauty and pleasure (and their opposites) are perfused throughout learning activity. Designing for aesthetic experience overtly -- building on the sensations of enjoyment and pleasure in the learning experience -- can motivate those who might feel alienated by the common conception of science as merely a dispassionate assembly of facts, discrete procedures or inaccessible theory.

    NASA Astrophysics Data System (ADS)

    Connor, C. L.; Prakash, A.

    2007-12-01

    Alaska's secondary school teachers are increasingly required to provide Earth systems science (ESS) education that integrates student observations of local natural processes related to rapid climate change with geospatial datasets and satellite imagery using Geographic Information Systems (GIS) technology. Such skills are also valued in various employment sectors of the state where job opportunities requiring Earth science and GIS training are increasing. University of Alaska's EDGE (Experiential Discoveries in Geoscience Education) program has provided training and classroom resources for 3 cohorts of inservice Alaska science and math teachers in GIS and Earth Systems Science (2005-2007). Summer workshops include geologic field experiences, GIS instruction, computer equipment and technical support for groups of Alaska high school (HS) and middle school (MS) science teachers each June and their students in August. Since 2005, EDGE has increased Alaska science and math teachers' Earth science content knowledge and developed their GIS and computer skills. In addition, EDGE has guided teachers using a follow-up, fall online course that provided more extensive ESS knowledge linked with classroom standards and provided course content that was directly transferable into their MS and HS science classrooms. EDGE teachers were mentored by University faculty and technical staff as they guided their own students through semester-scale, science fair style projects using geospatial data that was student- collected. EDGE program assessment indicates that all teachers have improved their ESS knowledge, GIS knowledge, and the use of technology in their classrooms. More than 230 middle school students have learned GIS, from EDGE teachers and 50 EDGE secondary students have conducted original research related to landscape change and its impacts on their own communities. Longer-term EDGE goals include improving student performance on the newly implemented (spring 2008) 10th grade

    Stöcker, Horst; Stöhlker, Thomas; Sturm, Christian

    2015-06-01

    To explore cosmic matter in the laboratory - this fascinating research prospect becomes available at the Facility for Antiproton and Ion Research, FAIR. The new facility is being constructed within the next five years adjacent to the existing accelerator complex of the GSI Helmholtz Centre for Heavy Ion Research at Darmstadt/Germany, expanding the research goals and technical possibilities substantially. This includes new insights into the dynamics of supernovae depending on the properties of short-lived neutron-rich nuclei which will be investigated with intense rare isotope beams. New insights will be provided into the interior of stars by exploring dense plasmas with intense heavy-ion beams combined with a high-performance laser - or into neutron star cores by probing the highest baryon densities in relativistic nucleus-nucleus collisions at unprecedented collision rates. To the latter, the properties of hadrons play an important part which will be systematically studied by high precision hadron spectroscopy with antiproton beams at unmatched intensities. The worldwide unique accelerator and experimental facilities of FAIR will open the way for a broad spectrum of unprecedented fore-front research supplying a large variety of experiments in hadron, nuclear, atomic and plasma physics as well as biomedical and material science which will be briefly described in this article. This article is based on the FAIR Green Paper [4] and gives an update of former publications [5] - [12].

  13. NASA's Earth Science Data Systems Standards Process Experiences

    NASA Technical Reports Server (NTRS)

    Ullman, Richard E.; Enloe, Yonsook

    2007-01-01

    NASA has impaneled several internal working groups to provide recommendations to NASA management on ways to evolve and improve Earth Science Data Systems. One of these working groups is the Standards Process Group (SPC). The SPG is drawn from NASA-funded Earth Science Data Systems stakeholders, and it directs a process of community review and evaluation of proposed NASA standards. The working group's goal is to promote interoperability and interuse of NASA Earth Science data through broader use of standards that have proven implementation and operational benefit to NASA Earth science by facilitating the NASA management endorsement of proposed standards. The SPC now has two years of experience with this approach to identification of standards. We will discuss real examples of the different types of candidate standards that have been proposed to NASA's Standards Process Group such as OPeNDAP's Data Access Protocol, the Hierarchical Data Format, and Open Geospatial Consortium's Web Map Server. Each of the three types of proposals requires a different sort of criteria for understanding the broad concepts of "proven implementation" and "operational benefit" in the context of NASA Earth Science data systems. We will discuss how our Standards Process has evolved with our experiences with the three candidate standards.

  15. Indiana secondary students' evolution learning experiences and demarcations of science from non-science

    NASA Astrophysics Data System (ADS)

    Donnelly, Lisa A.

    2007-12-01

    Previous research has documented students' conceptual difficulties learning evolution and how student learning may be related to students' views of evolution and science. This mixed methods study addressed how 74 high school biology students from six Indiana high schools viewed their evolution learning experiences, the demarcations of science from non-science, and evolution understanding and acceptance. Data collection entailed qualitative and quantitative methods including interviews, classroom observations, surveys, and assessments to address students' views of science and non-science, evolution learning experiences, and understanding and acceptance of evolution. Qualitative coding generated several demarcation and evolution learning experience codes that were subsequently used in quantitative comparisons of evolution understanding and acceptance. The majority of students viewed science as empirical, tentative but ultimately leading to certain truth, compatible with religion, the product of experimental work, and the product of human creativity. None of the students offered the consensus NOS view that scientific theories are substantiated explanations of phenomena while scientific laws state relationships or patterns between phenomena. About half the students indicated that scientific knowledge was subjectively and socio-culturally influenced. The majority of students also indicated that they had positive evolution learning experiences and thought evolution should be taught in secondary school. The quantitative comparisons revealed how students who viewed scientific knowledge as subjectively and socio-culturally influenced had higher understanding than their peers. Furthermore, students who maintained that science and religion were compatible did not differ with respect to understanding but had higher acceptance than their peers who viewed science and religion as conflicting. Furthermore, students who maintained that science must be consistent with their

  17. Modeling event building architecture for the triggerless data acquisition system for PANDA experiment at the HESR facility at FAIR/GSI

    NASA Astrophysics Data System (ADS)

    Korcyl, K.; Konorov, I.; Kühn, W.; Schmitt, L.

    2012-12-01

    A novel architecture is being proposed for the data acquisition and trigger system of the PANDA experiment at the HESR facility at FAIR/GSI. The experiment will run without hardware trigger signal using timestamps to correlate detector data from a given time window. The broad physics program in combination with the high rate of 2 * 107 interactions per second requires very selective filtering algorithms accessing information from many detectors. Therefore the effective filtering will happen later than in today's systems ie. after the event building. To assess that, the complete architecture will be built of two stages: the data concentrator stage providing event building and the rate reduction stage. For the former stage, which requires a throughput of 100 GB/s to perform event building, we propose two layers of ATCA crates filled with Compute Nodes - modules designed at IHEP and University of Giessen for trigger and data acquisition systems. Currently each board is equipped with 5 Virtex4 FX60 FPGAs and high bandwidth connectivity is provided by 8 front panel RocketIO ports and 12 backplane ports for the inter-module communication. We designed simplified models of the components of the architecture and using the SystemC library as support for the discrete event simulations, demonstrate the expected throughput of the full-size system. We also show impact of some architectural choices and key parameters on the architecture's performance.

    2001-01-01

    The selection, definition, and development phases of a Life Sciences flight research experiment has been consistent throughout the past decade. The implementation process, however, has changed significantly within the past two years. This change is driven primarily by the shift from highly integrated, dedicated research missions on platforms with well defined processes to self contained experiments with stand alone operations on platforms which are being concurrently designed. For experiments manifested on the International Space Station (ISS) and/or on short duration missions, the more modular, streamlined, and independent the individual experiment is, the more likely it is to be successfully implemented before the ISS assembly is completed. During the assembly phase of the ISS, science operations are lower in priority than the construction of the station. After the station has been completed, it is expected that more resources will be available to perform research. The complexity of implementing investigations increases with the logistics needed to perform the experiment. Examples of logistics issues include- hardware unique to the experiment; large up and down mass and volume needs; access to crew and hardware during the ascent or descent phases; maintenance of hardware and supplies with a limited shelf life,- baseline data collection schedules with lengthy sessions or sessions close to the launch or landing; onboard stowage availability, particularly cold stowage; and extensive training where highly proficient skills must be maintained. As the ISS processes become better defined, experiment implementation will meet new challenges due to distributed management, on-orbit resource sharing, and adjustments to crew availability pre- and post-increment. c 2001.

    An atmospheric sounding mission starts with a wide range of concept designs involving measurement technologies, observing platforms, and observation scenarios. Observing system simulation experiment (OSSE) is a technical approach to evaluate the relative merits of mission and instrument concepts. At Jet Propulsion Laboratory (JPL), the OSSE team has developed an OSSE environment that allows atmospheric scientists to systematically explore a wide range of mission and instrument concepts and formulate a science traceability matrix with a quantitative science impact analysis. The OSSE environment virtually creates a multi-platform atmospheric sounding testbed (MAST) by integrating atmospheric phenomena models, forward modeling methods, and inverse modeling methods. The MAST performs OSSEs in four loosely coupled processes, observation scenario exploration, measurement quality exploration, measurement quality evaluation, and science impact analysis.

  2. Norfolk State University Research Experience in Earth System Science

    2002-01-01

    The truly interdisciplinary nature of Earth System Science lends itself to the creation of research teams comprised of people with different scientific and technical backgrounds. In the annals of Earth System Science (ESS) education, the lack of an academic major in the discipline might be seen as a barrier to the involvement of undergraduates in the overall ESS-enterprise. This issue is further compounded at minority-serving institutions by the rarity of departments dedicated to Atmospheric Science, Oceanography or even the geosciences. At Norfolk State University, a Historically Black College, a six week, NASA-supported, summer undergraduate research program (REESS - Research Experience in Earth System Science) is creating a model that involves students with majors in diverse scientific disciplines in authentic ESS research coupled with a structured education program. The project is part of a wider effort at the University to enhance undergraduate education by identifying specific areas of student weaknesses regarding the content and process of science. A pre- and post-assessment test, which is focused on some fundamental topics in global climate change, is given to all participants as part of the evaluation of the program. Student attitudes towards the subject and the program's approach are also surveyed at the end of the research experience. In 2002, 11 undergraduates participated in REESS and were educated in the informed use of some of the vast remote sensing resources available through NASA's Earth Science Enterprise (ESE). The program ran from June 3rd through July 12, 2002. This was the final year of the project.

    We report here the instructional design of introductory science experiments for freshmen and the effectiveness of the designed classes in Tohoku University. These classes are intended to aid students in thinking logically, willingness to challenge and understanding the fundamental concepts of natural phenomena through writing reports. We combined physics, chemistry, biology and earth science and set up five themed course entitled Life, Energy, Earth and Environment, Materials, and Science and Culture. In every year, about 1,650 students of all the science-related freshmen have attended since we started in 2004. Of the students taking the classes, 62% were favorable to them in 2004, 72% in 2009 and 69% in 2012, whilst only 50% of the students were positive about the old classes in 2001.

  4. Family science: An ethnographic case study of the ordinary science and literacy experiences of one family

    NASA Astrophysics Data System (ADS)

    McCarty, Glenda M.

    Despite the copious research available on science learning, little is known about ways in which the public engages in free-choice science learning and even fewer studies have focused on how families engage in science to learn about the world around them. The same was true about studies of literacy development in the home until the 1980s when researchers (e.g. Bissex, 1980; Heath, 1983; Taylor, 1983) began documenting the literacy happenings and practices of young children in natural settings. Findings from intensive emergent literacy research studies have challenged traditional approaches to the teaching and learning of literacy, especially drawing attention to the active role children take in their own learning. Drawing upon those early literacy studies, this research project uses ethnographic case study methods along with a naturalistic inquiry approach, to document the daily explorations of one science-oriented family. Over a three year span, I have followed my own family, in our natural setting, through our day-to-day experiences with science and literacy as we seek to mediate and understand the world around us. In doing so, I have explored the ways we have shared knowledge and constructed learning through science books and read alouds, self-initiated inquiry learning, and communication. Throughout the three year research period, I have collected data and documented my own young children's understanding of the nature of science by observing their engagement with world around them.

    The Physical Science Informatics (PSI) system is the next step in this an effort to make NASA sponsored flight data available to the scientific and engineering community, along with the general public. The experimental data, from six overall disciplines, Combustion Science, Fluid Physics, Complex Fluids, Fundamental Physics, and Materials Science, will present some unique challenges. Besides data in textual or numerical format, large portions of both the raw and analyzed data for many of these experiments are digital images and video, requiring large data storage requirements. In addition, the accessible data will include experiment design and engineering data (including applicable drawings), any analytical or numerical models, publications, reports, and patents, and any commercial products developed as a result of the research. This objective of paper includes the following: Present the preliminary layout (Figure 2) of MABE data within the PSI database. Obtain feedback on the layout. Present the procedure to obtain access to this database.

    2013-06-01

    Teaching science to secondary students in an online environment is a growing international trend. Despite this trend, reports of empirical studies of this phenomenon are noticeably missing. With a survey concerning the nature of laboratory activities, this study describes the perspective of 35-secondary teachers from 15-different U.S. states who are teaching science online. The type and frequency of reported laboratory activities are consistent with the tradition of face-to-face instruction, using hands-on and simulated experiments. While provided examples were student-centered and required the collection of data, they failed to illustrate key components of the nature of science. The features of student-teacher interactions, student engagement, and nonverbal communications were found to be lacking and likely constitute barriers to the enactment of inquiry. These results serve as a call for research and development focused on using existing communication tools to better align with the activity of science such that the nature of science is more clearly addressed, the work of students becomes more collaborative and authentic, and the formative elements of a scientific inquiry are more accessible to all participants.

    Since 1983, the Spencer S. Eccles Health Sciences Library has presented InfoFair, an annual event featuring presentations, exhibits, demonstrations, and workshops on computer and information topics of interest to health professionals and health information providers at the University of Utah Health Sciences Center and throughout Utah. The first InfoFair was held in response to an increasing number of inquiries from library users on how to search MEDLINE from their home or office computers. The focus of InfoFair has expanded and changed over the past nineteen years to reflect changes in library users' computer and information needs, concerns, and interests. While themes and programs have changed, a definite set of trends, guidelines, and procedures have developed based on the experience gained each year. The purpose of this paper is to review and evaluate the changes in InfoFair from 1983 to 2001 and to present information for use by other libraries for planning and presenting similar events.

    2015-06-01

    While efforts have been made to understand the experiences of African students in predominantly white environments, the experiences of African students in clinical placement areas have rarely been explored. This paper is a report on a study designed to address the gap in educational research on the experiences of African health sciences students in clinical placements in predominantly white environments. Interviews adopting an open approach to conversations were conducted with nine African students from three health disciplines at one metropolitan university in Australia between 2012 and 2013. Interview transcripts were analyzed using philosophical hermeneutics, where shared meanings were arrived at by employing key Gadamerian hermeneutic components. Findings revealed a number of factors that had a direct effect on the meaning students derived from their clinical placement experiences. These, as revealed in the interlinked domains of body, space, relationships, and time included difference, acceptance, resilience, and cultural sensitivity. Insights from this study may lead to the adoption of strategies designed to improve the experiences of African students studying health sciences in predominantly white environments. PMID:24942056

  11. Observability of Rembrandt scarp with Mercury Radio Science Experiment

    NASA Astrophysics Data System (ADS)

    Junior Mariani, Mirco; Marabucci, Manuela; Di Achille, Gaetano

    2015-04-01

    The radio science experiment of the ESA mission BepiColombo (MORE, Mercury Orbiter Radio science Experiment) is devoted to the estimation of Mercury's gravity field with unprecedented accuracy, by means of highly stable, multi-frequency radio links in X and Ka band, provided by the Ka band transponder (KaT) on-board the Mercury Planetary Orbiter (MPO). The estimation of gravity field coefficients and planetary tidal deformation with radio science experiment will provide fundamental constraints for modelling planet interior, but additional analysis can be carried out in order to verify whether radio science can give a significant contribution in the study of other physical phenomena, like for example crustal thickening due to tectonic phenomena. This paper reports on the observability of Mercury scarps and crustal thickening with the Mercury Orbiter Radio science experiment, exploiting the extremely precise radio observables (range rate accuracies of 3 micron/s at 1000 s integration time at nearly all elongation angles, and range observables accuracies of 20 cm two-way). One of the largest surface structures of Mercury's surface is the Rembrandt scarp, which can be modeled with a length of 1000 km, an average width of 300 km and a height of 5 km, assuming a flat-ramp-flat tectonic geometry for its enucleation. In general, a surface structure can be observed with radio science if the variation in velocity due to the change in the gravitational potential is larger than the accuracy of the signal at an integration time equal to the interaction time between the spacecraft and the structure, e.g. about 100s for the Rembrandt scarp. Based on our simualtions, the gravity anomalies associated to the Rembrandt scarp can potentially produce effects on the spacecraft orbit that are significantly higher than the expected noise. Therefore, there is an excellent chance that the density contrast generated by the crustal thickness along the Rembrandt scarp will be measurable to a

    2007-06-13

    Understanding the interplay of the nuclear interaction with polarized protons and the electromagnetic interaction with polarized electrons in polarized atoms is crucial to progress towards the PAX goal to eventually produce stored polarized antiproton beams at FAIR. Presently, there exist two competing theoretical scenarios: one with substantial spin filtering of (anti)protons by atomic electrons, and a second one suggesting a self-cancellation of the electron contribution to spin filtering. After a brief review of the PAX physics case for polarized antiprotons at FAIR, a detailed discussion of future investigations, including spin-filtering experiments at COSY-Juelich and at the AD of CERN is presented.

  14. Mapping the entangled ontology of science teachers' lived experience

    NASA Astrophysics Data System (ADS)

    Daugbjerg, Peer S.; de Freitas, Elizabeth; Valero, Paola

    2015-09-01

    In this paper we investigate how the bodily activity of teaching, along with the embodied aspect of lived experience, relates to science teachers' ways of dealing with bodies as living organisms which are both the subject matter as well as the site or vehicle of learning. More precisely, the following questions are pursued: (1) In what ways do primary science teachers refer to the lived and living body in teaching and learning? (2) In what ways do primary science teachers tap into past experiences in which the body figured prominently in order to teach students about living organisms? We draw on the relational ontology and intra-action of Karen Barad (J Women Cult Soc 28(3): 801, 2003) as she argues for a "relational ontology" that sees a relation as a dynamic flowing entanglement of a matter and meaning. We combine this with the materialist phenomenological studies of embodiment by SungWon Hwang and Wolff-Michael Roth (Scientific and mathematical bodies, Sense Publishers, Rotterdam, 2011), as they address how the teachers and students are present in the classroom with/in their "living and lived bodies". Our aim is to use theoretical insights from these two different but complementary approaches to map the embodiment of teachers' experiences and actions. We build our understanding of experience on the work of John Dewey (Experience and education, Simon & Schuster, New York, 1938) and also Jean Clandinin and Michael Connelly (Handbook of qualitative research, Sage Publications, California, 2000), leading us to propose three dimensions: settings, relations and continuity. This means that bodies and settings are mutually entailed in the present relation, and furthermore that the past as well as the present of these bodies and settings—their continuity—is also part of the present relation. We analyse the entanglement of lived experience and embodied teaching using these three proposed dimensions of experience. Analysing interviews and observations of three Danish

  15. A New Model for Climate Science Research Experiences for Teachers

    NASA Astrophysics Data System (ADS)

    Hatheway, B.

    2012-12-01

    After two years of running a climate science teacher professional development program for secondary teachers, science educators from UCAR and UNC-Greeley have learned the benefits of providing teachers with ample time to interact with scientists, informal educators, and their teaching peers. Many programs that expose teachers to scientific research do a great job of energizing those teachers and getting them excited about how research is done. We decided to try out a twist on this model - instead of matching teachers with scientists and having them do science in the lab, we introduced the teachers to scientists who agreed share their data and answer questions as the teachers developed their own activities, curricula, and classroom materials related to the research. Prior to their summer experience, the teachers took three online courses on climate science, which increased their background knowledge and gave them an opportunity to ask higher-level questions of the scientists. By spending time with a cohort of practicing teachers, each individual had much needed time to interact with their peers, share ideas, collaborate on curriculum, and learn from each other. And because the goal of the program was to create classroom modules that could be implemented in the coming school year, the teachers were able to both learn about climate science research by interacting with scientists and visiting many different labs, and then create materials using data from the scientists. Without dedicated time for creating these classroom materials, it would have been up to the teachers to carve out time during the school year in order to find ways to apply what they learned in the research experience. We feel this approach worked better for the teachers, had a bigger impact on their students than we originally thought, and gave us a new approach to teacher professional development.

  16. The influence of field experiences on stages of concern and attitudes of preservice teachers toward science and science teaching

    NASA Astrophysics Data System (ADS)

    Strawitz, Barbara M.; Malone, Mark R.

    The purpose of the study was to determine whether the field experience component of an undergraduate science methods course influenced teachers' concerns and attitudes toward science and science teaching. Age, grade-point average, openmindedness, and school assignment were examined as factors which might explain some of the variance in the dependent measures. A one-group pretest-posttest design was used. Students were administered the Teacher Concerns Questionnaire, the Science Teaching Attitude Scales, and the Rokeach Dogmatism Scale approximately eight weeks after the pretest. Results indicated that field experiences did not significantly change student concerns about teaching science but significantly improved student attitudes toward science and science teaching. Students differing in age, grade-point average, and openmindedness did not difer significantly in changes in concerns and changes in attitude toward science and science teaching. Students assigned to different schools differed significantly in changes in attitude toward science.

    The Compressed Baryonic Matter (CBM) experiment at FAIR is composed of 8 tracking stations consisting of 1292 double sided silicon micro-strip sensors. For the quality assurance of produced prototype sensors a laser test system (LTS) has been developed. The aim of the LTS is to scan sensors with a pulsed infra-red laser driven by step motor to determine the charge sharing in-between strips and to measure qualitative uniformity of the sensor response over the whole active area. The prototype sensors which are tested with the LTS so far have 256 strips with a pitch of 50 μm on each side. They are read-out using a self-triggering prototype read-out electronic ASIC called n-XYTER. The LTS is designed to measure sensor response in an automatized procedure at several thousand positions across the sensor with focused infra-red laser light (spot size ≈ 12 μm , wavelength = 1060 nm). The pulse with duration (≈ 10 ns) and power (≈ 5 mW) of the laser pulses is selected such, that the absorption of the laser light in the 300 μm thick silicon sensors produces a number of about 24000 electrons, which is similar to the charge created by minimum ionizing particles (MIP) in these sensors. Laser scans different prototype sensors is reported.

    2007-05-01

    The Facility for Antiproton and Ion Research, FAIR, is a new particle accelerator facility to be built at the GSI site in Germany. The research at FAIR will cover a wide range of topics in nuclear and hadron physics, high density plasma and atomic physics, and applications in condensed matter physics and biology. A 1.1 km circumference double ring of rapidly cycling 100 and 300 Tm synchrotrons, will be FAIR's central accelerator system. It will be used to produce, inter alia, high intensity secondary beams of antiprotons and short-lived radioactive nuclei. A subsequent suite of cooler and storage rings will deliver heavy ion and antiproton beams of unprecedented quality. Large experiments are presently being designed by the NUSTAR, PANDA, PAX, CBM, SPARC, FLAIR, HEDgeHOB and BIOMAT collaborations.

    The selection, definition, and development phases of a Life Sciences flight research experiment has been consistent throughout the past decade. The implementation process, however, has changed significantly within the past two years. This change is driven primarily by the shift from highly integrated, dedicated research missions on platforms with well defined processes to self contained experiments with stand alone operations on platforms which are being concurrently designed. For experiments manifested on the International Space Station (ISS) and/or on short duration missions, the more modular, streamlined, and independent the individual experiment is, the more likely it is to be successfully implemented before the ISS assembly is completed. During the assembly phase of the ISS, science operations are lower in priority than the construction of the station. After the station has been completed, it is expected that more resources will be available to perform research. The complexity of implementing investigations increases with the logistics needed to perform the experiment. Examples of logistics issues include- hardware unique to the experiment; large up and down mass and volume needs; access to crew and hardware during the ascent or descent phases; maintenance of hardware and supplies with a limited shelf life,- baseline data collection schedules with lengthy sessions or sessions close to the launch or landing; onboard stowage availability, particularly cold stowage; and extensive training where highly proficient skills must be maintained. As the ISS processes become better defined, experiment implementation will meet new challenges due to distributed management, on-orbit resource sharing, and adjustments to crew availability pre- and post-increment.

  20. Influencing attitudes toward science through field experiences in biology

    NASA Astrophysics Data System (ADS)

    Carpenter, Deborah Mcintyre

    The purpose of this study was to determine how student attitudes toward science are influenced by field experiences in undergraduate biology courses. The study was conducted using two institutions of higher education including a 2-year lower-level and a 2-year upper-level institution. Data were collected through interviews with student participants, focus group discussions, students' journal entries, and field notes recorded by the researcher during the field activities. Photographs and video recordings were also used as documentation sources. Data were collected over a period of 34 weeks. Themes that emerged from the qualitative data included students' beliefs that field experiences (a) positively influence student motivation to learn, (b) increase student ability to learn the concepts being taught, and (c) provide opportunities for building relationships and for personal growth. The findings of the study reinforce the importance of offering field-study programs at the undergraduate level to allow undergraduate students the opportunity to experience science activities in a field setting. The research study was framed by the behavioral and developmental theories of attitude and experience including the Theory of Planned Behavior (Ajzen, 1991) and the Theory of Experiential Learning (Kolb, 1984).

  1. Organizing Science Popularization and Teacher Training Workshops : A Nigerian Experience

    NASA Astrophysics Data System (ADS)

    Okpala, Kingsley; Okere, Bonaventure

    Funding for science popularization has become a huge challenge in recent times especially for developing countries like Nigeria. However, a change in the school system from the 6-3-3-4 system (6 years primary, 3 years Junior secondary, 3year senior secondary, and 4 years tertiary education) to the 9-3-4 system ( 9 years junior basic, 3 years secondary, and 4 tertiary education) has made it even more convenient to strategically target the students through their teachers to attain the desired quality of education since the introduction of space science into the curriculum at the primary and secondary levels. Considering the size of Nigeria, there Is need for a shift in paradigm for sourcing resources to tackle this deficiency in a sustainable manner. Recently a teacher training and science popularization workshop was organized as a first in a series of subsequent workshops geared towards having a sustainable means of popularizing Science in Nigeria. Principally, the key lies in the partnership with the colleges of education which produce the teachers for primary schools in addition to the usual governmental actions. Experiences from this workshop will be enumerated with the hope of inspiring the same success in similar societies.

    SMART-1 is the first European Space Agency mission to the Moon. The primary ob- jective of the mission is to test and validate a new electric propulsion engine for poten- tial use on other larger ESA cornerstone missions. However the SMART-1 spacecraft will also carry a number of scientific instruments and experiments for use en-route to and in Orbit about the Moon. The payload comprises several instruments and ex- periments: the Asteroid Moon Micro Imager Experiment (AMIE), the Demonstration Compact Imaging X-ray Spectrometer (D-CIXS), the X-ray Solar Monitor (XSM), the SMART-1 Near-Infrared Spectrometer (SIR), the Electric Propulsion Diagnostic Package (EPDP), the Deep Space X/Ka Band TTC Experiment (KaTE), the Radio Science Investigation for SMART-1 (RSIS), and the Spacecraft Potential, Electron and Dust Experiment (SPEDE). During Lunar Orbit, the great majority of scientific activ- ities will be carried out. The AMIE multispectral high resolution camera will mainly aim to image the lunar South Pole and map the southern regions of the Moon. D-CIXS will look for the spatial distribution of major lunar rock types and the X-ray emission from impact of solar wind electrons on the night-side Moon. SIR will gather data to study the mineralogy of the lunar surface. During this phase the RSIS experiment will also take place, using AMIE images and the high accuracy tracking provided by KaTE to measure the lunar libration. Also in the frame of the mission a co-ordinated utilization of the experiments is envisaged. The Science and Technology Operations Co-Ordination (STOC) will be in charge of this task. The STOC will, in face of the capabilities of the experiments, advise experiments teams, to study specific features of the Moon at the same time. The data acquired this way, when cross-checked, will be able to produce higher value results. The STOC will also study SMART-1 data in comparison with former Moon data. Examples of these activities and what enhanced science

    2015-04-01

    FAIRNESS 2014 was the third edition in a series of workshops designed to bring together excellent international young scientists with research interests focused on physics at FAIR (Facility for Antiproton and Ion Research) and was held on September 22-27 2014 in Vietri sul Mare, Italy. The topics of the workshops cover a wide range of aspects in both theoretical developments and current experimental status, concentrated around the four scientific pillars of FAIR. FAIR is a new accelerator complex with brand new experimental facilities, that is currently being built next to the existing GSI Helmholtzzentrum for Schwerionenforschung close to Darmstadt, Germany. The spirit of the conference is to bring together young scientists, e.g. advanced PhD students and postdocs and young researchers without permanent position to present their work, to foster active informal discussions and build up of networks. Every participant in the meeting with the exception of the organizers gives an oral presentation, and all sessions are followed by an hour long discussion period. During the talks, questions are anonymously collected in a box to stimulate discussions. The broad physics program at FAIR is reflected in the wide range of topics covered by the workshop: • Physics of hot and dense nuclear matter, QCD phase transitions and critical point • Nuclear structure, astrophysics and reactions • Hadron Spectroscopy, Hadrons in matter and Hypernuclei • New developments in atomic and plasma physics • Special emphasis is put on the experiments CBM, HADES, PANDA, NUSTAR, APPA and related experiments For each of these different areas one invited speaker was selected to give a longer introductory presentation. The write-ups of the talks presented at FAIRNESS 2014 are the content of this issue of Journal of Physics: Conference Series and have been refereed according to the IOP standard for peer review. This issue constitutes therefore a collection of the forefront of research that

    The third in a series of Spacelab Mission Development tests was conducted at the Johnson (correction of Johnston) Space Center as a part of the development of Life Sciences experiments for the Space Shuttle era. The latest test was a joint effort of the Ames Research and Johnson Space Centers and utilized animals and men for study. The basic objective of this test was to evaluate the operational concepts planned for the Space Shuttle life science payloads program. A three-man crew (Mission Specialist and two Payload Specialists) conducted 26 experiments and 12 operational tests, which were selected for this 7-day mission simulation. The crew lived on board a simulated Orbiter/Spacelab mockup 24 hr a day. The Orbiter section contained the mid deck crew quarters area, complete with sleeping, galley and waste management provisions. The Spacelab was identical in geometry to the European Space Agency Spacelab design, complete with removable rack sections and stowage provisions. Communications between the crewmen and support personnel were configured and controlled as currently planned for operational shuttle flights. For this test a Science Operations Remote Center was manned at the Ames Research Center and was managed by simulated Mission Control and Payload Operation Control Centers at the Johnson Space Center. This paper presents the test objectives, description of the facilities and test program, and the results of this test.

    Research experiences for science teachers are an important mechanism for increasing classroom teachers' science content knowledge and facility with "real world" research processes. We have developed and implemented a summer scientific research and education workshop model for high school teachers and students which promotes classroom science inquiry projects and produces important research results supporting our overarching scientific agenda. The summer training includes development of a scientific research framework, design and implementation of preliminary studies, extensive field research and training in and access to instruments, measurement techniques and statistical tools. The development and writing of scientific papers is used to reinforce the scientific research process. Using these skills, participants collaborate with scientists to produce research quality data and analysis. Following the summer experience, teachers report increased incorporation of research inquiry in their classrooms and student participation in science fair projects. This workshop format was developed for an NSF Biocomplexity Research program focused on the interaction of urban climates, air quality and human response and can be easily adapted for other scientific research projects.

    2010-03-01

    In this paper we respond to Staver's article (this issue) on an attempt to resolve the discord between science and religion. Most specifically, we comment on Staver's downplaying of difference between Catholics and Protestants in order to focus on the religion-science question. It is our experience that to be born into one or other of these traditions in some parts of the world (especially Northern Ireland) resulted in starkly contrasting opportunities, identities and practices in becoming and being science educators. The paper starts with a short contextual background to the impact of religion on schooling and higher education in Northern Ireland. We then explore the lives and careers of three science/religious educators in Northern Ireland: Catholic (Jim) and Protestant (Ivor) males who are contemporaries and whose experience spans pre-Troubles to post-conflict and a Catholic female (Colette) who moved to Northern Ireland during the Troubles as a teenager. Finally, we discuss the situation regarding the teaching of creationism and evolution in Northern Ireland—an issue has recently generated high public interest. The Chair of the Education Committee of the Northern Ireland Assembly recently stated that "creationism is not for the RE class because I believe that it can stand scientific scrutiny and that is a debate which I am quite happy to encourage and be part of…" (News Letter 2008). It could be the case that the evolution debate is being fuelled as a deliberate attempt to undermine some of the post-conflict collaboration projects between schools and communities in Northern Ireland.

    The effects of climate change are being revealed at alarming rates in the Arctic and Boreal regions of the planet. NASA's Terrestrial Ecology Program has launched a major field campaign to study these effects over the next 5 to 8 years. The Arctic Boreal Vulnerability Experiment (ABoVE) will challenge scientists to take measurements in the field, study remote observations, and even run models to better understand the impacts of a rapidly changing climate for areas of Alaska and western Canada. The NASA Center for Climate Simulation (NCCS) at the Goddard Space Flight Center (GSFC) has partnered with the Terrestrial Ecology Program to create a science cloud designed for this field campaign - the ABoVE Science Cloud. The cloud combines traditional high performance computing with emerging technologies to create an environment specifically designed for large-scale climate analytics. The ABoVE Science Cloud utilizes (1) virtualized high-speed InfiniBand networks, (2) a combination of high-performance file systems and object storage, and (3) virtual system environments tailored for data intensive, science applications. At the center of the architecture is a large object storage environment, much like a traditional high-performance file system, that supports data proximal processing using technologies like MapReduce on a Hadoop Distributed File System (HDFS). Surrounding the storage is a cloud of high performance compute resources with many processing cores and large memory coupled to the storage through an InfiniBand network. Virtual systems can be tailored to a specific scientist and provisioned on the compute resources with extremely high-speed network connectivity to the storage and to other virtual systems. In this talk, we will present the architectural components of the science cloud and examples of how it is being used to meet the needs of the ABoVE campaign. In our experience, the science cloud approach significantly lowers the barriers and risks to organizations

    After five years experience in bringing American students to meet and learn with Russian students in Kamchatka and bringing Russian students to meet and learn with American students in Alaska, it is possible to make some generalizations about the problems and benefits this growing program. Some 200 students, including many from other countries besides the United States and Russian Federation, have now had this experience. The context of their collaboration is the International Volcanological Field School, sponsored by the University of Alaska Fairbanks, Kamchatka State University, and the Institute of Volcanology and Seismology, and also a comparison of Mount St Helens, Bezymianny, and Shiveluch volcanoes under the National Science Foundation's Partnerships in International Research in Education, with important support from the Russian Academy of Sciences, Far East Division. Elements of these two projects are adaptation to unfamiliar, harsh, and remote environments; intensive courses in Russian language, history, geography, and culture; and sharing of research and education experiences among students. The challenges faced by the program are: · Slow and complex visa processes. · Demise of a direct airline connection, necessitating round-the-world travel to go 3000 km. · Adequately communicating to students beforehand the need for physical fitness, mental fortitude in uncomfortable conditions, and patience when bad weather limits mobility. Benefits of the projects have been: · Experiences that students report to be career- and life-changing. · Much more positive perceptions of Russia and Russian people by American students and of America and Americans by Russian students. · Introduction to the "expedition style" volcanology necessary in challenging environments. · Development of long-lasting collaborations and friendships in the context of international science. Students often comment that hearing about what their peers have done or are doing in research at

    NASA-JPL and Japan's Institute of Space and Astronautical Science collaborated at the Usuda Deep Space Center in the Voyager-2 Neptune occultation experiment. Phase information is extracted from the recorded data by means of a digital filter that can track the carrier frequency and narrow the filter bandwidth by up to 3 mHz. The results thus obtained can verify the phase-stability of the receiving system as a whole. Problems experienced by low-noise amplifiers were solved through the use of system redundancies.

    Approaches to the planning and realization of Spacelab life sciences experiments, which may involve as many as 16 Space Shuttle missions and 100 tests, are discussed. In particular, a Spacelab simulation program, designed to evaluate problems associated with the use of live animal specimens, the constraints imposed by zero gravity on equipment operation, training of investigators and data management, is described. The simulated facility approximates the hardware and support systems of a current European Space Agency Spacelab model. Preparations necessary for the experimental program, such as crew activity plans, payload documentation and inflight experimental procedures are developed; health problems of the crew, including human/animal microbial contamination, are also assessed.

    The Life Sciences experiment program for the Shuttle/Spacelab has basically two scientific objectives. The first objective is related to an understanding and interpretation of the medical data from Skylab. The second objective is concerned with a utilization of the space environment, notably the very low g field, as an experimental variable in a broad range of fundamental studies. The program considered will use the pressurized module, almost exclusively, and will aim toward the greatest investigator participation in flight that is possible. Facilities must be provided to support such requirements as tissue biopses, blood, urine and tissue collections, and microbial and plant manipulations.

    Colleges and universities across the country and around the world have embraced the Earth system approach to gain deeper understanding of the interrelationships of processes that define the home planet. The Design Guide for Undergraduate Earth System Science Education, a product of the NASA/USRA Earth System Science Education for the 21st Century Program (ESSE 21), represents a synthesis of community understanding of the content and process of teaching and learning about Earth as a system. The web-based Design Guide serves faculty from multiple disciplines who wish to adopt an ESS approach in their own courses or programs. Illustrating the nine topical sections of the Design Guide are a series of short vignettes telling the story of how ESS is being used in the classroom, how ESS has contributed to institutional change and personal professional development, how ESS is being implemented at minority serving institutions, and the impact of ESS education on student research. Most vignettes are written from a personal perspective and reflect a direct experience with Earth System Science Education. Over forty vignettes have been assembled aiming to put a face on the results of the systemic reform efforts of the past fifteen years of the ESSE programs, documenting the sometimes intangible process of education reform to be shared with those seeking examples of ESS education. The vignettes are a vital complement to the Design Guide sections, and are also available as a separate collection on the Design Guide and ESSE 21 web sites.

  19. Evaluation of a High School Fair Program for Promoting Successful Inquiry-based Learning

    NASA Astrophysics Data System (ADS)

    Betts, Julia Nykeah

    The success of inquiry-based learning (IBL) in supporting science literacy can be challenged when students encounter obstacles in the absence of proper support. This research is intended to evaluate the effectiveness of an Oregon public school district's regional science fair coaching program in promoting inquiry skills and positive attitudes toward science in participating high school students. The purpose of this study was to better understand students' perception of program support, obstacles or barriers faced by students, and potential benefits of IBL facilitated by the science fair program. Data included responses to informal and semi-structured interviews, an anonymous survey, a Skills assessment of final project displays, and an in-depth case study on three students' experiences. Results suggest that the science fair program can properly engage participants in authentic IBL. However, when assessing the participant's final project displays, I found that previous fair experience did not significantly increase mean scores as identified by the official Oregon Department of Education (ODE) scoring guides. Based on results from the case study, it is suggested that participants' low science self-concept, poor understanding of inquiry skills, and inability to engage in reflective discourse may reduce students' abilities to truly benefit. Recommendations to address this discrepancy include identifying specific needs of students through a pre--fair survey to develop more targeted support, and providing new opportunities to develop skills associated with science-self concept, understanding of inquiry and reflective discourse. In addition, results suggest that students would benefit from more financial support in the form of grants, and more connections with knowledgeable mentors.

    Telecommunication systems of spacecraft on deep-space missions also function as instruments for radio science experiments. Several missions augmented the radio communication system with an ultrastable oscillator (USO) in order to provide a highly stable reference signal for one-way downlink. Since the first quartz USO was flown on Voyager, the technology has advanced significantly, affording future missions higher sensitivity in reconstructing the temperature-pressure profiles of the atmospheres under study as well as the ability to study other physical phenomena of interest to radio science. The ultrastable class of oscillators has been flown on Voyagers I and II, the Galileo Orbiter, the Galileo Probe, Mars Observer, and Mars Global Surveyor. These have been quartz crystal resonators. The Cassini spacecraft will carry another quartz USO and two rubidium USOs for the Huygens Probe in support of the Doppler Wind Experiment. There are plans to fly USOs on several other future missions. This article surveys the trends in stability and spectral purity performance; design characteristics, including size and mass; and the history of these clocks in space.

    Fairmont State University (FSU) and the West Virginia Geological and Economic Survey (WVGES) provided a small pilot group of West Virginia science teachers with a professional development session designed to mimic experiences obtained by geology majors during a typical summer field camp. Called GEOTECH, the program served as a research capstone event complimenting the participants' multi-year association with the RockCamp professional development program. GEOTECH was funded through a Improving Teacher Quality Grant administered by West Virginia Higher Education Policy Commission. Over the course of three weeks, eight GEOTEACH participants learned field measurement and field data collection techniques which they then applied to the construction of a surficial geologic map. The program exposed participants to authentic scientific processes by emphasizing the authentic scientific application of content knowledge. As a secondary product, it also enhanced their appreciation of the true nature of science in general and geology particular. After the session, a new appreciation of the effort involved in making a geologic map emerged as tacit knowledge ready to be transferred to their students. The program was assessed using pre/post instruments, cup interviews, journals, artifacts (including geologic maps, field books, and described sections), performance assessments, and constructed response items. Evaluation of the accumulated data revealed an increase in participants demonstrated use of science content knowledge, an enhanced awareness and understanding of the processes and nature of geologic mapping, positive dispositions toward geologic research and a high satisfaction rating for the program. These findings support the efficacy of the experience and document future programmatic enhancements.

    Science return from the Mars Reconnaissance Orbiter (MRO) High Resolution Imaging Science Experiment (HiRISE) will be optimized by maximizing science participation in the experiment. MRO is expected to arrive at Mars in March 2006, and the primary science phase begins near the end of 2006 after aerobraking (6 months) and a transition phase. The primary science phase lasts for almost 2 Earth years, followed by a 2-year relay phase in which science observations by MRO are expected to continue. We expect to acquire approx. 10,000 images with HiRISE over the course of MRO's two earth-year mission. HiRISE can acquire images with a ground sampling dimension of as little as 30 cm (from a typical altitude of 300 km), in up to 3 colors, and many targets will be re-imaged for stereo. With such high spatial resolution, the percent coverage of Mars will be very limited in spite of the relatively high data rate of MRO (approx. 10x greater than MGS or Odyssey). We expect to cover approx. 1% of Mars at approx. 1m/pixel or better, approx. 0.1% at full resolution, and approx. 0.05% in color or in stereo. Therefore, the placement of each HiRISE image must be carefully considered in order to maximize the scientific return from MRO. We believe that every observation should be the result of a mini research project based on pre-existing datasets. During operations, we will need a large database of carefully researched 'suggested' observations to select from. The HiRISE team is dedicated to involving the broad Mars community in creating this database, to the fullest degree that is both practical and legal. The philosophy of the team and the design of the ground data system are geared to enabling community involvement. A key aspect of this is that image data will be made available to the planetary community for science analysis as quickly as possible to encourage feedback and new ideas for targets.

  6. Providing Middle School Students With Science Research Experiences Through Community Partnerships

    Science research courses have been around for years at the university and high school level. As inquiry based learning has become more and more a part of the science teacher's vocabulary, many of these courses have adopted an inquiry model for studying science. Learners of all ages benefit from learning through the natural process of inquiry. I participated in the CIRES Earthworks program for science teachers (Colorado University) in the summer of 2007 and experienced, first hand, the value of inquiry learning. With the support and vision of my school administration, and with the support and commitment of community partners, I have developed a Middle School Science Research Program that is transforming how science is taught to students in my community. Swift Creek Middle School is located in Tallahassee, Florida. There are approximately 1000 students in this suburban public school. Students at Swift Creek are required to take one science class each year through 8th grade. As more emphasis is placed on learning a large number of scientific facts and information, in order to prepare students for yearly, standardized tests, there is a concern that less emphasis may be placed on the process and nature of science. The program I developed draws from the inquiry model followed at the CIRES Earthworks program, utilizes valuable community partnerships, and plays an important role in meeting that need. There are three major components to this Middle School Research Program, and the Center for Integrated Research and Learning (CIRL) at the National High Magnetic Field Lab (NHMFL) at Florida State University is playing an important role in all three. First, each student will develop their own research question and design experiments to answer the question. Scientists from the NHMFL are serving as mentors, or "buddy scientists," to my students as they work through the process of inquiry. Scientists from the CIRES - Earthworks program, Florida State University, and other

    This science data report describes the Optical Properties Monitor (OPM) experiment and the data gathered during its 9-mo exposure on the Mir space station. Three independent optical instruments made up OPM: an integrating sphere spectral reflectometer, vacuum ultraviolet spectrometer, and a total integrated scatter instrument. Selected materials were exposed to the low-Earth orbit, and their performance monitored in situ by the OPM instruments. Coinvestigators from four NASA Centers, five International Space Station contractors, one university, two Department of Defense organizations, and the Russian space company, Energia, contributed samples to this experiment. These materials included a number of thermal control coatings, optical materials, polymeric films, nanocomposites, and other state-of-the-art materials. Degradation of some materials, including aluminum conversion coatings and Beta cloth, was greater than expected. The OPM experiment was launched aboard the Space Shuttle on mission STS-81 in January 1997 and transferred to the Mir space station. An extravehicular activity (EVA) was performed in April 1997 to attach the OPM experiment to the outside of the Mir/Shuttle Docking Module for space environment exposure. OPM was retrieved during an EVA in January 1998 and was returned to Earth on board the Space Shuttle on mission STS-89.

  8. Expanding educational access and opportunities: The globalization and foreign direct investment of multinational corporations and their influence on STEM, project-based learning and the national science and technology fair in schools in Costa Rica

    NASA Astrophysics Data System (ADS)

    Valdez, Joaquin G.

    The purpose of this qualitative study was to examine the influence of globalization and the foreign direct investment (FDI) of multinational corporations (MNCs) on the curriculum in schools in Costa Rica. The study focused primarily on Science, Technology, Engineering and Mathematics (STEM), Project-Based Learning (PBL), 21st century skills, and the national science and technology fair. The high influx of MNCs such as Intel has changed the global and educational culture of the country increasing the number of knowledge-based workers in Costa Rica. As a result, policy changes have been instituted in education to mirror the demands of sustaining the country's global economy. This study was supported by the creation of three research questions that would attempt to answer 1) the extent that teachers implementing STEM curriculum trace their practices back to policy, globalization, and multinational corporations as well as the extent to which the economic growth of Costa Rica and STEM education are related, 2) how mandating the national science and technology fair has influenced 21st century skills through project-based learning and the use of technology by teachers and its impact on curriculum and instruction, and 3) how has the national science and technology fair policy changed the value of STEM education for students, teachers, and educational leaders. To further understand the outcome of this study, four theoretical frameworks were applied that included, Spring's theory of world educational culture, Friedman's world flatteners, Wagner's 21st century skills and partnerships for 21st century skills, and Slough and Milam's STEM project-based learning theoretical framework. Each framework was applied to support the changes to the educational system; survival skills necessary to compete in the global job market; application of 21st century skills in the classroom and in the science projects students created. A research team comprised of 14 doctoral students, led by Dr

    1999-01-01

    The Performance Goal for NASA's Microgravity Materials Science Program reads "Use microgravity to establish and improve quantitative and predictive relationships between the structure, processing and properties of materials." The advent of the International Space Station will open up a new era in Materials Science Research including the ability to perform long term and frequent experiments in microgravity. As indicated the objective is to gain a greater understanding of issues of materials science in an environment in which the force of gravity can be effectively switched off. Thus gravity related issues of convection, buoyancy and hydrostatic forces can be reduced and the science behind the structure/processing/properties relationship can more easily be understood. The specific areas of research covered within the program are (1) the study of Nucleation and Metastable States, (2) Prediction and Control of Microstructure (including pattern formation and morphological stability), (3) Phase Separation and Interfacial Stability, (4) Transport Phenomena (including process modeling and thermophysical properties measurement), and (5) Crystal Growth, and Defect Generation and Control. All classes of materials, including metals and alloys, glasses and ceramics, polymers, electronic materials (including organic and inorganic single crystals), aerogels and nanostructures, are included in these areas. The principal experimental equipment available to the materials scientist on the International Space Station (ISS) will be the Materials Science Research Facility (MSRF). Each of these systems will be accommodated in a single ISS rack, which can operate autonomously, will accommodate telescience operations, and will provide real time data to the ground. Eventual plans call for three MSRF racks, the first of which will be shared with the European Space Agency (ESA). Under international agreements, ESA and other partners will provide some of the equipment, while NASA covers launch

  10. Research experience and inquiry: Uses and effects of authentic environments in science education

    NASA Astrophysics Data System (ADS)

    Steward, Jason Lee

    Within the last twenty years, reform documents have been penned in order to define and codify standards for improved science education practices. A major theme within these documents is the attainment of student understanding of the nature of science through tasks that more closely resemble how science really works. My research deals with two specific approaches to authenticity in science education: inquiry-based teaching in middle-school and high-school and a research experience for undergraduates (REU) program in chemical biology. Through my research, I have made four assertions about authenticity in science education: (1) Educators' research experiences lend credibility to students' own science education experiences, (2) Undergraduate students give ownership priority over science-like activities when assessing authenticity, (3) Educators need support to implement authentic science activities (including inquiry) into the classroom setting, and (4) Students (and educators) at all levels benefit from experiences with authentic science practices.

  12. An Investigation of the Effects of Authentic Science Experiences Among Urban High School Students

    NASA Astrophysics Data System (ADS)

    Chapman, Angela

    Providing equitable learning opportunities for all students has been a persistent issue for some time. This is evident by the science achievement gap that still exists between male and female students as well as between White and many non-White student populations (NCES, 2007, 2009, 2009b) and an underrepresentation of female, African-American, Hispanic, and Native Americans in many science, technology, engineering, and mathematics (STEM) related careers (NCES, 2009b). In addition to gender and ethnicity, socioeconomic status and linguistic differences are also factors that can marginalize students in the science classroom. One factor attributed to the achievement gap and low participation in STEM career is equitable access to resources including textbooks, laboratory equipment, qualified science teachers, and type of instruction. Extensive literature supports authentic science as one way of improving science learning. However, the majority of students do not have access to this type of resource. Additionally, extensive literature posits that culturally relevant pedagogy is one way of improving education. This study examines students' participation in an authentic science experience and argues that this is one way of providing culturally relevant pedagogy in science classrooms. The purpose of this study was to better understand how marginalized students were affected by their participation in an authentic science experience, within the context of an algae biofuel project. Accordingly, an interpretivist approach was taken. Data were collected from pre/post surveys and tests, semi-structured interviews, student journals, and classroom observations. Data analysis used a mixed methods approach. The data from this study were analyzed to better understand whether students perceived the experience to be one of authentic science, as well as how students science identities, perceptions about who can do science, attitudes toward science, and learning of science practices

    Atmospheric electricity is one of the oldest experimental topics in atmospheric science. The fair weather aspects, although having less dramatic effects than thunderstorm electrification, link the microscale behaviour of ion clusters to currents flowing on the global scale. This talk will include a survey of some past measurements and measurement methods, as atmospheric electrical data from a variety of sites and eras are now being used to understand changes in atmospheric composition. Potential Gradient data was the original source of information on the global atmospheric electrical circuit, and similar measurements can now be used to reconstruct past air pollution concentrations, and black carbon loading.

  16. Development of interest in science and interest in teaching elementary science: Influence of informal, school, and inquiry methods course experiences

    NASA Astrophysics Data System (ADS)

    Bulunuz, Mizrap

    Inquiry-based science instruction is a major goal of science education reform. However, there is little research examining how preservice elementary teachers might be motivated to teach through inquiry. This quantitative study was designed to examine the role of background experiences and an inquiry science methods course on interest in science and interest in teaching science. The course included many activities and assignments at varying levels of inquiry, designed to teach content and inquiry methods and to model effective teaching. The study involved analyses of surveys completed by students in the course on their experiences with science before, during, and at the end of the course. The following questions guided the design of this study and analysis of the data: (1) What science background experiences (school, home, and informal education) do participants have and how do those experiences affect initial interest in science? (2) Among the hands-on activities in the methods course, is there a relationship between level of inquiry of the activity and the motivational quality (interesting, fun, and learning) of the activity? (3) Does the course affect participants' interest and attitude toward science? (4) What aspects of the course contribute to participants' interest in teaching science and choice to teach science? Descriptive and inferential analysis of a background survey revealed that participants with high and low initial interest in science differed significantly on remembering about elementary school science and involvement in science related activities in childhood/youth. Analysis of daily ratings of each hands-on activity on motivational qualities (fun, interest, and learning) indicated that there were significant differences in motivational quality of the activities by level of inquiry with higher levels of inquiry rated more positively. Pre/post surveys indicated that participants increased in interest in science and a number of variables reflecting

    Experimental research has become complex and thus a challenge to science education. Only very few students can typically be trained on advanced scientific equipment. It is therefore important to find new tools that allow all students to acquire laboratory skills individually and independent of where they are located. In a design-based research process we have investigated the feasibility of using a virtual laboratory as a photo-realistic and scientifically valid representation of advanced scientific infrastructure to teach modern experimental science, here, molecular quantum optics. We found a concept based on three educational principles that allows undergraduate students to become acquainted with procedures and concepts of a modern research field. We find a significant increase in student understanding using our Simulated Interactive Research Experiment (SiReX), by evaluating the learning outcomes with semi-structured interviews in a pre/post design. This suggests that this concept of an educational tool can be generalized to disseminate findings in other fields.

    During summers 2011 and 12 Montclair State University hosted a Research Experience for Undergraduates Program (REU) in transdisciplinary, hands-on, field-oriented research in environmental sciences. Participants were housed at the Montclair State University's field station situated in the middle of 30,000 acres of mature forest, mountain ridges and freshwater streams and lakes within the Kittatinny Mountains of Northwest New Jersey, Program emphases were placed on development of project planning skills, analytical skills, creativity, critical thinking and scientific report preparation. Ten students were recruited in spring with special focus on recruiting students from underrepresented groups and community colleges. Students were matched with their individual research interests including hydrology, erosion and sedimentation, environmental chemistry, and ecology. In addition to research activities, lectures, educational and recreational field trips, and discussion on environmental ethics and social justice played an important part of the program. The ultimate goal of the program is to facilitate participants' professional growth and to stimulate the participants' interests in pursuing Earth Science as the future career of the participants.

    The Tritium Plasma Experiment (TPE) is a unique high-flux linear plasma device that can handle beryllium, tritium, and neutron-irradiated plasma facing materials, and is the only existing device dedicated to directly study tritium retention and permeation in neutron-irradiated materials [M. Shimada et.al., Rev. Sci. Instru. 82 (2011) 083503 and and M. Shimada, et.al., Nucl. Fusion 55 (2015) 013008]. Recently the TPE has undergone major upgrades in its electrical and control systems. New DC power supplies and a new control center enable remote plasma operations from outside of the contamination area for tritium, minimizing the possible exposure risk with tritium and beryllium. We discuss the electrical upgrade, enhanced operational safety, improved plasma performance, and development of tritium plasma-driven permeation and optical spectrometer system. This upgrade not only improves operational safety of the worker, but also enhances plasma performance to better simulate extreme plasma-material conditions expected in ITER, Fusion Nuclear Science Facility (FNSF), and Demonstration reactor (DEMO). This work was prepared for the U.S. Department of Energy, Office of Fusion Energy Sciences, under the DOE Idaho Field Office contract number DE-AC07-05ID14517.

    The present lack of a lower atmosphere research satellite program for the 1980s has prompted consideration of the Space Shuttle/Spacelab system as a means of flying sensor complements geared toward specific research problems, as well as continued instrument development. Three specific examples of possible science questions related to precipitation are discussed: (1) spatial structure of mesoscale cloud and precipitation systems, (2) lightning and storm development, and (3) cyclone intensification over oceanic regions. Examples of space sensors availab le to provide measurements needed in addressing these questions are also presented. Distinctive aspects of low-earth orbit experiments would be high resolution, multispectral sensing of atmospheric phenomena by complements of instruments, and more efficient sensor development through reflights of specific hardware packages.

    The Horizon Science Experiment (HORSE) utilizes the Mars Horizon Sensor Assembly (MHSA) on the Mars Global Surveyor (MGS) orbiter to measure 15-micron band thermal emission from the Martian atmosphere. During the first two phases of aerobraking, from September 1997 to May 1998, and from September 1998 to March 1999, one of the four MGS quadrants was pointed well onto the planet consistently during the near-periapsis aerobraking passes, allowing the device to obtain data on the latitudinal variation of middle atmospheric temperature (0.2 - 2.0 mbar). Of particular interest during the first phase (L(sub s) = 182 - 300 deg) were the effects of a prominent dust storm at L(sub s) =224 deg, and wavelike behavior in the strong temperature gradient near the north polar cap. Additional information is contained in the original extended abstract.

    2005-01-01

    The education research community no longer has a means of being manifested on Space Shuttle flights, and small orbital payload carriers must be flown as secondary payloads on ELV flights, as their launch schedule, secondary payload volume and mass permits. This has resulted in a backlog of small payloads, schedule and cost problems, and an inability for the small payloads community to achieve routine, low-cost access to orbit. This paper will discuss Goddard's Wallops Flight Facility funded effort to leverage its core competencies in small payloads, sounding rockets, balloons and range services to develop a low cost, multiple payload ejector (MPE) carrier for orbital experiments. The goal of the MPE is to provide a low-cost carrier intended primarily for educational flight research experiments. MPE can also be used by academia and industry for science, technology development and Exploration experiments. The MPE carrier will take advantage of the DARPAI NASA partnership to perform flight testing of DARPA s Falcon small, demonstration launch vehicle. The Falcon is similar to MPE fiom the standpoint of focusing on a low-cost, responsive system. Therefore, MPE and Falcon complement each other for the desired long-term goal of providing the small payloads community with a low-cost ride to orbit. The readiness dates of Falcon and MPE are complementary, also. MPE is being developed and readied for flight within 18 months by a small design team. Currently, MPE is preparing for Critical Design Review in fall 2005, payloads are being manifested on the first mission, and the carrier will be ready for flight on the first Falcon demonstration flight in summer, 2006. The MPE and attached experiments can weigh up to 900 lb. to be compatible with Falcon demonstration vehicle lift capabilities fiom Wallops, and will be delivered to the Falcon demonstration orbit - 100 nautical mile circular altitude.

    The NASA Capacity Building Program (Earth Science Division, Applied Sciences Program) works to enhance end-user capabilities to employ Earth observation and Earth science (EO/ES) data in decision-making. Open data access and user-tailored data delivery strategies are critical elements towards this end. User Experience (UX) and User Interface (UI) research methods can offer important contributions towards addressing data access challenges, particularly at the interface of science application/product development and product transition to end-users. This presentation focuses on developing nation contexts and describes methods, results, and lessons learned from two recent UX/UI efforts conducted in collaboration with NASA: the SERVIRglobal.net redesign project and the U.S. Water Partnership (USWP) Portal development effort. SERVIR, a collaborative venture among NASA, USAID, and global partners, seeks to improve environmental management and climate change response by helping governments and other stakeholders integrate EO and geospatial technologies into decision-making. The USWP, a collaboration among U.S. public and private sectors, harnesses U.S.-based resources and expertise to address water challenges in developing nations. SERVIR's study, conducted from 2010-2012, assessed and tested user needs, preferences, and online experiences to generate a more user-friendly online data portal at SERVIRglobal.net. The portal provides a central access interface to data and products from SERVIR's network of hubs in East Africa, the Hindu Kush Himalayas, and Mesoamerica. The second study, conducted by the USWP Secretariat and funded by the U.S. Department of State, seeks to match U.S.-based water information resources with developing nation stakeholder needs. The USWP study utilizes a multi-pronged approach to identify key design requirements and to understand the existing water data portal landscape. Adopting UX methods allows data distributors to design customized UIs that

    2015-03-01

    The Plains Elevated Convection at Night (PECAN) experiment is a large field campaign that is being supported by the National Science Foundation (NSF) with contributions from the National Oceanic and Atmospheric Administration (NOAA), the National Atmospheric and Space Administration (NASA), and the U.S. Department of Energy (DOE). The overarching goal of the PECAN experiment is to improve the understanding and simulation of the processes that initiate and maintain convection and convective precipitation at night over the central portion of the Great Plains region of the United States (Parsons et al. 2013). These goals are important because (1) a large fraction of the yearly precipitation in the Great Plains comes from nocturnal convection, (2) nocturnal convection in the Great Plains is most often decoupled from the ground and, thus, is forced by other phenomena aloft (e.g., propagating bores, frontal boundaries, low-level jets [LLJ], etc.), (3) there is a relative lack of understanding how these disturbances initiate and maintain nocturnal convection, and (4) this lack of understanding greatly hampers the ability of numerical weather and climate models to simulate nocturnal convection well. This leads to significant uncertainties in predicting the onset, location, frequency, and intensity of convective cloud systems and associated weather hazards over the Great Plains.

Foundation courses (e.g., 100 level) often have a mixture of majors and non-majors for any given discipline, thus confounding student engagement. Experiential learning provides students with opportunities to apply theory with application. In any given course, a suite of methods may need to be employed to attain the highest level of engagement. Northern Virginia Community College is a two-year institution with a strong commitment to the sciences. In this presentation, a variety of methods for student engagement will be discussed including: in-class assignments, modules in the laboratory as well as modules involving the campus, independent research experiences, and activities linking students with professionals in the area. Within the context of these methods, there will also be discussions on expectations, limitations, and successes as well as failures.

    Despite the emergence of and widespread uptake of a growing range of medical and scientific professions in elite sport, such environs present a volatile professional domain characterized by change and unprecedentedly high turnover of personnel. This study explored sport medicine and science practitioners' experiences of organizational change using a longitudinal design over a 2-year period. Specifically, data were collected in three temporally defined phases via 49 semi-structured interviews with 20 sport medics and scientists employed by three organizations competing in the top tiers of English football and cricket. The findings indicated that change occurred over four distinct stages; anticipation and uncertainty, upheaval and realization, integration and experimentation, normalization and learning. Moreover, these data highlight salient emotional, behavioral, and attitudinal experiences of medics and scientists, the existence of poor employment practices, and direct and indirect implications for on-field performance following organizational change. The findings are discussed in line with advances to extant change theory and applied implications for prospective sport medics and scientists, sport organizations, and professional bodies responsible for the training and development of neophyte practitioners.

    The accurate measurement of density in both liquid and solid samples is of considerable interest to Principal Investigators with materials science experiments slated for the ISS. The work to be described is an innovative application of a conventional industrial nondestructive evaluation instrument. Traditional applications of industrial computed tomography (CT) rely on reconstructing cross sections of large structures to provide two-dimensional planar views which can identify defects such as porosity, or other material anomalies. This has been done on microgravity materials science experiments to check the integrity of ampoule-cartridge assemblies for safety purposes. With a substantially monoenergetic flux, as can be obtained with a radioactive cobalt source, there will be a direct correlation between absorption and density. Under such conditions it then becomes possible to make accurate measurements of density throughout a sample, and even when the sample itself is enclosed within a furnace and a safety required cartridge. Such a system has been installed at Kennedy Space Center (KSC) and is available to PIs to examine samples before and after flight. The CT system is being used to provide density information for two purposes. Firstly, the determination of density changes from liquid to solid is vital information to the PI for purposes of modeling the solidification behavior of his sample, and to engineers who have to design containment ampoules and must allow for shrinkage and other volume changes that may occur during processing. While such information can be obtained by pycnometric measurements, the possibility of using a furnace installed on the CT system enables one to examine potentially dangerous materials having high vapor pressures, while not needing visible access to the material. In addition, uniform temperature can readily be obtained, and the system can be controlled to ramp up, hold, and ramp down while collecting data over a wide range of

    The visceral appeal of space science and exploration is a very powerful emotional connection to a very large and diverse collection of people, most of whom have little or no perspective about what it means to do science and engineering. Therein lies the potential of space for a substantially enhanced positive impact on culture through education. This essay suggests that through engaging more of the space research and development community in enabling unique and 'meaningful educational experiences' for educators and students at the pre-collegiate levels, space science and exploration can amplify its positive feedback on society and act as an important medium for cultural transformation to greater science literacy. I discuss the impact of space achievements on people and define what is meant by a 'meaningful educational experience,' all of which points to the need for educators and students to be closer to the practice of real science. I offer descriptions of two nascent science education programs associated with NASA which have the needed characteristics for providing meaningful experiences that can cultivate greater science literacy. Expansion of these efforts and others like it will be needed to have the desired impact on culture, but I suggest that the potential for the needed resources is there in the scientific research communities. A society in which more people appreciate and understand science and science methods would be especially conducive to human progress in space and on Earth.

  4. Fairness in technological design.

    PubMed

    Shelley, Cameron

    2012-12-01

    This paper addresses an important multi-disciplinary issue of current interest, that is, the implications of technological design for fairness. A visual, graphical methodology centered on the Taylor-Russell diagram is proposed to address this issue. The Taylor-Russell diagram helps to identify and explore ways in which predictions built into designs can pit the interests of different constituencies against one another. The configuration of the design represents a trade-off between the interests of the communities involved. Whether or not the trade-off is appropriate constitutes a problem of fairness or distributive justice. The breadth of this methodology is supported by a diversity of examples analyzed. These include a surveillance system, an automotive safety system, a civic information system, and the international food distribution system. These examples provide models for application of the methodology to the analysis of designs in further areas of concern. Limitations of the methodology are also discussed. While it helps to identify and clarify issues of fairness in technology design, the methodology does not provide a general theory of fairness, nor can it provide fair solutions to such issues without appeal to further principles or concepts.

    The capabilities of the Space Station glovebox facility is described. Tentatively scheduled to be launched in 1999, this facility called the Microgravity Sciences Glovebox (MSG), will provide a robust and sophisticated platform for doing microgravity experiments on the Space Station. It will provide an environment not only for testing and evaluating experiment concepts, but also serve as a platform for doing fairly comprehensive science investigations. Its design has evolved substantially from the middeck glovebox, now flown on Space Shuttle missions, not only in increased experiment volume but also in significant capability enhancements. The system concept, functionality and architecture are discussed along with technical information that will benefit potential science investigators.

  6. Surface science experiments involving the atomic force microscope

    NASA Astrophysics Data System (ADS)

    McBride, Sean P.

    Three diverse first author surfaces science experiments conducted by Sean P. McBride1-3 will be discussed in detail and supplemented by secondary co-author projects by Sean P. McBride,4-7 all of which rely heavily on the use of an atomic force microscope (AFM). First, the slip length parameter, b of liquids is investigated using colloidal probe AFM. The slip length describes how easily a fluid flows over an interface. The slip length, with its exact origin unknown and dependencies not overwhelming decided upon by the scientific community, remains a controversial topic. Colloidal probe AFM uses a spherical probe attached to a standard AFM imaging tip driven through a liquid. With the force on this colloidal AFM probe known, and using the simplest homologous series of test liquids, many of the suspected causes and dependencies of the slip length demonstrated in the literature can be suppressed or eliminated. This leaves the measurable trends in the slip length attributed only to the systematically varying physical properties of the different liquids. When conducting these experiments, it was realized that the spring constant, k, of the system depends upon the cantilever geometry of the experiment and therefore should be measured in-situ. This means that the k calibration needs to be performed in the same viscous liquid in which the slip experiments are performed. Current in-situ calibrations in viscous fluids are very limited, thus a new in-situ k calibration method was developed for use in viscous fluids. This new method is based upon the residuals, namely, the difference between experimental force-distance data and Vinogradova slip theory. Next, the AFM's ability to acquire accurate sub nanometer height profiles of structures on interfaces was used to develop a novel experimental technique to measure the line tension parameter, tau, of isolated nanoparticles at the three phase interface in a solid-liquid-vapor system. The tau parameter is a result of excess energy

  7. The efficacy of planetarium experiences to teach specific science concepts

    NASA Astrophysics Data System (ADS)

    Palmer, Joel C.

    The purpose of this study was to examine the impact of planetarium experiences on students' understanding of phases of the moon and eclipses. This research employed a quasi-experimental design. Students from 12 classes in four different schools all in the same school district participated in the study. A total of 178 students from four teachers participated in the study. Data were collected using a researcher developed pretest and posttest. All students received classroom instruction based on the school district's curriculum. The experimental groups took the posttest after attending a 45-minute planetarium experience titled Moon Witch. The control groups took the posttest before attending the planetarium experience but after receiving an additional 45-minute lesson on phases of the moon and eclipses. The data were analyzed using the Statistical Package for Social Sciences (SPSS). An Analysis of Variance (ANOVA) was run to determine if there was variance among teachers' instructional practices. Since the results indicated there was no significant variance among teachers, the study sample was analyzed as a single group. An Independent Samples t Test for Means was run in SPSS for the study sample and each subgroup. Subgroups were African American, Hispanic, White, Male, Female, and Economically Disadvantaged. The results indicated that there was an improvement on mean gain scores for the experimental group over the control group for all students and each subgroup. The differences in mean gain scores were significantly higher for all students and for the African American, Female, and Economically Disadvantaged subgroups. An Independent Samples t Test for Means was run using SPSS for each of the three different sections of the pretest and posttest. The results indicated that most of the improvement was in Section 3. This section required students to manipulate photos of the phases of moon into correct order. This section required more spatial reasoning than Section 1

    2009-08-01

    There has been a recent surge in interest in hosted and rideshare payloads that would launch aboard commercial communications satellites. Much of this interest originates with the satellite customers themselves as a way to sell excess mass and power margins that exist at launch. In 2008, NASA selected GOLD (Global-scale Observations of the Limb and Disk) as a mission of opportunity to fly as its first hosted payload experiment on a geosynchronous commercial communications satellite, a STAR-2 bus satellite built by Orbital Sciences. CHIRP (Commercially Hosted Infrared Payload), a hosted payload to test infrared sensors for the Air Force, is also being developed for a STAR-2 bus communications satellite. The mass limitation on a STAR-2 bus hosted payload is roughly 50 - 60 kg and the volume is roughly constrained to a 25" x 30" x 28" box on the nadir deck. Telescope apertures are therefore limited is size to about 50 cm in diameter. The diffraction limit for visible (much less IR) imaging missions barely improves upon ground-based image performance, but UV missions can achieve better than 0.1" resolution. There is at least one family of optical designs that (a) provide the necessary focal length and (b) are light and compact enough to fit within the STAR-2 bus mass and volume constraints. These designs also afford opportunities to maintain 0.05" pointing accuracy through a combination of a fine steering mirror and an orthogonal transfer CCD.

    The European Union (EU) adopted the first legislation on chemicals management in 1967 with the Dangerous Substances Directive (DSD). Over time the underlying concepts evolved: from hazard identification over risk assessment to safety assessment. In 1981 a premarketing notification scheme was introduced. Approximately 10 years later a risk assessment program started for existing substances following a data collection and prioritization exercise. Integration of science into EU chemicals legislation occurred via several technical committees managed by the European Chemicals Bureau (ECB) and resulted in the Technical Guidance Document on Risk Assessment (TGD), which harmonized the risk assessment methodology. The TGD was revised several times to adapt to scientific developments. The revision process, and the risk assessments for new and existing substances, led to scientific research on chemical risk assessment and thus increased in complexity. The new EU chemicals policy REACH (Registration, Evaluation, Authorization and Restriction of CHemicals) builds on previous experiences and aims to further enhance health and safety. REACH places the burden of proof for chemical safety on industry focusing on managing risks. REACH formalizes the precautionary principle. Furthermore, it underlines a continued scientific underpinning in its implementation, also via stakeholder involvement, and a focus on aligning with international fora. PMID:20958022

    2012-01-01

    Science exists to refute dogmas; nevertheless, dogmas may be introduced when undemonstrated scientific axioms lead us to reject facts incompatible with them. Several studies have proposed psychobiological interpretations of near-death experiences (NDEs), claiming that NDEs are a mere byproduct of brain functions gone awry; however, relevant facts incompatible with the ruling physicalist and reductionist stance have been often neglected. The awkward transcendent look of NDEs has deep epistemological implications, which call for: (a) keeping a rigorously neutral position, neither accepting nor refusing anything a priori; and (b) distinguishing facts from speculations and fallacies. Most available psychobiological interpretations remain so far speculations to be demonstrated, while brain disorders and/or drug administration in critical patients yield a well-known delirium in intensive care and anesthesia, the phenomenology of which is different from NDEs. Facts can be only true or false, never paranormal. In this sense, they cannot be refused a priori even when they appear implausible with respect to our current knowledge: any other stance implies the risk of turning knowledge into dogma and the adopted paradigm into a sort of theology.

    1998-09-01

    The Horizon Science Experiment (HORSE) uses the Mars Horizon Sensor Assembly on the MGS orbiter to measure 15 micrometer band thermal emission from the Martian atmosphere. During the first phase of aerobraking for MGS, from September 1997 through March 1998, one of the four MGS quadrants was pointed well onto the planet consistently during the near-periapsis braking passes, allowing the device to obtain data on the latitudinal variation of middle atmospheric temperature (0.2 - 2 mbar). Of particular interest were the effects of a prominent dust storm at Ls 224, and the strong gradient of temperature near the north polar cap. The dust storm produced 10-12K warming in the middle atmosphere across the latitude range from -50 to +60 degrees over a time period of 97 hrs. The increase was most pronounced at the longitudes near 330 where the storm originated in the southern hemisphere. During Ls 260-278, the latitude of steepest latitudinal temperature gradient (the location of the northern polar vortex) varied with longitude in a primarily wave 2 mode, with an amplitude of about 8 degrees and one maximum at 120 longitude. A small wave 1 term is also present.

    The purpose of this investigation was to examine the effects of a year long intensive extracurricular middle school science experience on the self-esteem, career goal orientation, and attitude toward science of eighth grade female students using both quantitative and qualitative methods. Sixteen self-selected eighth grade female students participated in extracurricular science experiences such as camping, rock climbing, specimen collecting and hiking, as well as meeting and interacting with female science role models. Data was collected using pre- and posttest methods using the Children's Attitude Toward Science Survey, the Coopersmith Self-Esteem Inventory, and the Self-Directed Search (SDS) Career Explorer. End of year science course grades were examined for seventh and eighth grades and compared to first semester high school grades. Qualitative data was in the form of: (1) focus group interviews conducted prior to field experiences, at the end of all field experiences, and at the end of the first semester of high school, and (2) journal entries from throughout the project. Qualitative data was examined for changes in student perceptions of science as a discipline, self as scientist, women in science, and social comparison of self in science.

    2013-12-01

    In case studies of two first-year elementary classroom teachers, we explored the influence of informal science education (ISE) they experienced in their teacher education program. Our theoretical lens was identity development, delimited to classroom science teaching. We used complementary data collection methods and analysis, including interviews, electronic communications, and drawing prompts. We found that our two participants referenced as important the ISE experiences in their development of classroom science identities that included resilience, excitement and engagement in science teaching and learning-qualities that are emphasized in ISE contexts. The data support our conclusion that the ISE experiences proved especially memorable to teacher education interns during the implementation of the No Child Left Behind policy which concentrated on school-tested subjects other than science.

  3. Engaging science practice through science practitioners: Design experiments in K-12 telementoring

    NASA Astrophysics Data System (ADS)

    O'Neill, David Kevin

    Some educational networking enthusiasts think of the Internet primarily as a delivery vehicle for learning resources. Others see its value as a bridge between people, institutions and work routines: a way to bridge communities of discourse/practice which have traditionally been separated, so that students may have more authentic educational experiences. This dissertation reports on a set of design experiments conducted in collaboration with a high school and a middle school teacher around "telementoring": the use of telecommunications to support the development of mentoring relationships between students in school and adults in workplaces. Over the 1995/96 school year, the participants in this research orchestrated curriculum-based mentoring relationships between 90 students in project-based science classes and more than a hundred volunteer scientists from government, academia and industry. The design and evaluation carried out in these experiments had three major foci: activity structures to support productive, ongoing discourse between students and telementors, network services to reduce the administrative workload that telementoring requires of teachers, and strategies to determine how students' written arguments about their research were influenced by telementoring. Individual chapters consider how telementoring could help improve science education on a large scale; describe the activity structures implemented in each classroom and the rationale behind them; present in-depth case studies of successful and unsuccessful telementoring relationships; and discuss the implications of the research for the design of telementoring programs. The methods employed include surveys of students, interviews with students, teachers and volunteers, a broad-based topical coding of telementoring dialogues, and a unique form of genre analysis applied to students' final written reports of their research. One important finding from the research is that teams of students who invested

  4. Change over a service learning experience in science undergraduates' beliefs expressed about elementary school students' ability to learn science

    NASA Astrophysics Data System (ADS)

    Goebel, Camille A.

    This longitudinal investigation explores the change in four (3 female, 1 male) science undergraduates' beliefs expressed about low-income elementary school students' ability to learn science. The study sought to identify how the undergraduates in year-long public school science-teaching partnerships perceived the social, cultural, and economic factors affecting student learning. Previous service-learning research infrequently focused on science undergraduates relative to science and society or detailed expressions of their beliefs and field practices over the experience. Qualitative methodology was used to guide the implementation and analysis of this study. A sample of an additional 20 science undergraduates likewise involved in intensive reflection in the service learning in science teaching (SLST) course called Elementary Science Education Partners (ESEP) was used to examine the typicality of the case participants. The findings show two major changes in science undergraduates' belief expressions: (1) a reduction in statements of beliefs from a deficit thinking perspective about the elementary school students' ability to learn science, and (2) a shift in the attribution of students, underlying problems in science learning from individual-oriented to systemic-oriented influences. Additional findings reveal that the science undergraduates perceived they had personally and profoundly changed as a result of the SLST experience. Changes include: (1) the gain of a new understanding of others' situations different from their own; (2) the realization of and appreciation for their relative positions of privilege due to their educational background and family support; (3) the gain in ability to communicate, teach, and work with others; (4) the idea that they were more socially and culturally connected to their community outside the university and their college classrooms; and (5) a broadening of the way they understood or thought about science.

    Preservice science teachers face numerous challenges in understanding and teaching science as inquiry. Over the course of their teacher education program, they are expected to move from veteran science students with little experience learning their discipline through inquiry instruction to beginning science teachers adept at implementing inquiry in their own classrooms. In this study, we used Aikenhead's (Sci Educ 81: 217-238, 1997, Science Educ 85:180-188, 2001) notion of border crossing to describe this transition preservice teachers must make from science student to science teacher. We examined what one cohort of eight preservice secondary science teachers said, did, and wrote as they both conducted a two-part inquiry investigation and designed an inquiry lesson plan. We conducted two types of qualitative analyses. One, we drew from Costa (Sci Educ 79: 313-333, 1995) to group our preservice teacher participants into one of four types of potential science teachers. Two, we identified successes and struggles in preservice teachers' attempts to negotiate the cultural border between veteran student and beginning teacher. In our implications, we argue that preservice teachers could benefit from explicit opportunities to navigate the border between learning and teaching science; such opportunities could deepen their conceptions of inquiry beyond those exclusively fashioned as either student or teacher.

    The purposes of this study were, based on John Dewey's ideas on experience, to examine how primary students used their own everyday experience and were affected by own and others' experience in science discourse, and to illuminate the implications of experience in science education. To do these, science discourses by a group of six fourth-graders were observed, where they talked about their ideas related to thermal concepts. The data was collected through interviews and open-ended questions, analyzed based on Dewey's perspective, and depicted as the discourse map which was developed to illustrate students' transaction and changing process of students' ideas. The results of the analysis showed typical examples of Dewey's notions of experience, such as the principles of continuity and of transaction and of different types of experience, examples of `the expanded continuity and transaction', and science discourse as inquiry. It was also found that students' everyday experiences played several roles: as a rebuttal for changing their own ideas or others', backing for assurance of their own ideas in individual students' inner changes after discourse with others, and backing for other's ideas. Based on these observations, this study argues that everyday experience should be considered as a starting point for primary students' science learning because most of their experience comes from everyday, not school science, contexts. In addition, to evoke educative experience in science education, it is important for teachers to pay more attention to Dewey's notions of the principles of continuity and of transaction and to their educational implications.

    The High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter (MRO) acquired 8 terapixels of data in 9137 images of Mars between October 2006 and December 2008, covering ???0.55% of the surface. Images are typically 5-6 km wide with 3-color coverage over the central 20% of the swath, and their scales usually range from 25 to 60 cm/pixel. Nine hundred and sixty stereo pairs were acquired and more than 50 digital terrain models (DTMs) completed; these data have led to some of the most significant science results. New methods to measure and correct distortions due to pointing jitter facilitate topographic and change-detection studies at sub-meter scales. Recent results address Noachian bedrock stratigraphy, fluvially deposited fans in craters and in or near Valles Marineris, groundwater flow in fractures and porous media, quasi-periodic layering in polar and non-polar deposits, tectonic history of west Candor Chasma, geometry of clay-rich deposits near and within Mawrth Vallis, dynamics of flood lavas in the Cerberus Palus region, evidence for pyroclastic deposits, columnar jointing in lava flows, recent collapse pits, evidence for water in well-preserved impact craters, newly discovered large rayed craters, and glacial and periglacial processes. Of particular interest are ongoing processes such as those driven by the wind, impact cratering, avalanches of dust and/or frost, relatively bright deposits on steep gullied slopes, and the dynamic seasonal processes over polar regions. HiRISE has acquired hundreds of large images of past, present and potential future landing sites and has contributed to scientific and engineering studies of those sites. Warming the focal-plane electronics prior to imaging has mitigated an instrument anomaly that produces bad data under cold operating conditions. ?? 2009 Elsevier Inc.

    Equity in education relies on equal access to learning experiences and fair play during those experiences. Too often policy makers, voters and even some educators define equity only in terms of equal access. Equity is less about the same treatment for all and more about holding everyone to the same high standards and high expectations. All…
