    Family oriented innovative programs extend the reach of many traditional out-of-school venues to involve the entire family in learning in comfortable and fun environments. Research shows that parental involvement is key to increasing student achievement outcomes, and family-oriented programs have a direct impact on student performance. Because families have the greatest influence on children's attitudes towards education and career choices, we have developed a Family Science program that provides families a venue where they can explore the importance of science and technology in our daily lives by engaging in learning activities that change their perception and understanding of science. NASA Family Science Night strives to change the way that students and their families participate in science, within the program and beyond. After three years of pilot implementation and assessment, our evaluation data shows that Family Science Night participants have positive change in their attitudes and involvement in science.  Even after a single session, families are more likely to engage in external science-related activities and are increasingly excited about science in their everyday lives.  As we enter our dissemination phase, NASA Family Science Night will be compiling and releasing initial evaluation results, and providing facilitator training and online support resources. Support for NASA Family Science Nights is provided in part through NASA ROSES grant NNH06ZDA001N.

  2. Virtual Globes: Serving Science and Society

    Full Text Available Virtual Globes reached the mass market in 2005. They created multi-million dollar businesses in a very short time by providing novel ways to explore data geographically. We use the term “Virtual Globes” as the common denominator for technologies offering capabilities to annotate, edit and publish geographic information to a world-wide audience and to visualize information provided by the public and private sectors, as well as by citizens who volunteer new data. Unfortunately, but not surprising for a new trend or paradigm, overlapping terms such as “Virtual Globes”, “Digital Earth”, “Geospatial Web”, “Geoportal” or software specific terms are used heterogeneously. We analyze the terminologies and trends in scientific publications and ask whether these developments serve science and society. While usage can be answered quantitatively, the authors reason from the literature studied that these developments serve to educate the masses and may help to democratize geographic information by extending the producer base. We believe that we can contribute to a better distinction between software centered terms and the generic concept as such. The power of the visual, coupled with the potential of spatial analysis and modeling for public and private purposes raises new issues of reliability, standards, privacy and best practice. This is increasingly addressed in scientific literature but the required body of knowledge is still in its infancy.

    Impacts: The BES program supports basic research that underpins a broad range of energy technologies. Research in materials sciences and engineering leads to the development of materials that improve the efficiency, economy, environmental acceptability, and safety of energy generation, conversion, transmission, storage, and use. For example, advances in superconductivity have been introduced commercially in a number of demonstration projects around the country. Improvements in alloy design for high temperature applications are used in commercial furnaces and in green technologies such as lead-free solder. Research in chemistry has led to advances such as efficient combustion systems with reduced emissions of pollutants; new solar photoconversion processes; improved catalysts for the production of fuels and chemicals; and better separations and analytical methods for applications in energy processes, environmental remediation, and waste management. Research in geosciences results in advanced monitoring and measurement techniques for reservoir definition and an understanding of the fluid dynamics of complex fluids through porous and fractured subsurface rock. Research in the molecular and biochemical nature of photosynthesis aids the development of solar photo-energy conversion. The BES program also plays a major role in enabling the nanoscale revolution. The importance of nanoscience to future energy technologies is clearly reflected by the fact that all of the elementary steps of energy conversion (e.g., charge transfer, molecular rearrangement, and chemical reactions) take place on the nanoscale. The development of new nanoscale materials, as well as the methods to characterize, manipulate, and assemble them, create an entirely new paradigm for developing new and revolutionary energy technologies.

    education class. Study outcomes include self-reported tendencies toward increased awareness of science teaching techniques and content, as well as pleasure, confidence, and family interactions around science. The survey amplifies these findings among a larger group. Negative cases and difficulties are discussed. This study suggests that the availability of mothers' informal science teaching/learning experience is one way to create a more pervasively supportive environment for science education. There is increased opportunity for women as adult learners, to be positive role models, and to mediate family settings. Recommendations are made for recruiting mothers as teachers and fulfilling their motivations. Informal science education theory is discussed

    2013-09-27

    This project, “Building Surface Science Capacity to Serve the Automobile Industry in Southeastern Michigan” was carried out in two phases: (1) the 2009 – 2012 renovation of space in the new EMU Science Complex, which included the Surface Science Laboratory (SSL), a very vigorous research lab at EMU that carries on a variety of research projects to serve the auto and other industries in Michigan; and (2) the 2013 purchase of several pieces of equipment to further enhance the research capability of the SSL. The funding granted by the DoE was proposed to “renovate the space in the Science Complex to include SSL and purchase equipment for tribological and electrochemical impedance measurements in the lab, thus SSL will serve the auto and other industries in Michigan better.” We believe we have fully accomplished the mission.

  7. Making the Introductory Meteorology Class Relevant in a Minority Serving Community College

    2008-12-01

    Queensborough Community College (QCC), a constituent campus of the City University of New York (CUNY), has modified the introductory Meteorology Class lecture and lab to include active learning activities and discovery based learning. The modules were developed at QCC and other 4 year colleges and designed to introduce basic physical concepts important in meteorology. The modules consisted of either interactive lecture demonstrations or discovery-based activities. The discovery based activities are intended to have students become familiar with scientific investigation. Students engage in formulating hypotheses, developing and carrying out experiments, and analyzing scientific data. These activities differ from traditional lab experiments in that they avoid "cookbook" procedures and emphasize having the students learn about physical concepts by applying the scientific method. During the interactive lecture demonstrations the instructor describes an experiment/phenomenon that is to be demonstrated in class. Students discuss the phenomenon based on their experiences and make a prediction about the outcome. The class then runs the experiment, makes observations, and compares the expected results to the actual outcome. As a result of these activities students in the introductory Meteorology class scored higher in exams questions measuring conceptual understanding, as well as factual knowledge. Lower scoring students demonstrated the greatest benefit, while the better students had little (or no) changes. All students also had higher self-efficacy scores after the intervention, compared to an unmodified class.

    The International Ocean Discovery Program (IODP) is an international marine research collaboration that explores Earth's history and dynamics using ocean-going research platforms to recover data recorded in seafloor sediments and rocks and to monitor subseafloor environments. The JOIDES Resolution is the flagship vessel of IODP and is operated by the National Science Foundation. It is an inspirational hook for STEM Earth and ocean topics for children and the general public of all ages, but is not easily accessible due to its international travels and infrequent U.S. port calls. In response, a consortium of partners has created the Pop-Up/Drill Down Science project. The multi-year project, funded by NSF's Advancing Informal Science Learning program, aims to bring the JR and its science to under-served and rural populations throughout the country. Consisting of an inflatable walk-through ship, a multi-media experience, a giant interactive seafloor map and a series of interactive exhibit kiosks, the exhibit, entitled, In Search of Earth's Secrets: A Pop-Up Science Encounter, will travel to 12 communities throughout the next four years. In each community, the project will partner with local institutions like public libraries and small museums as hosts and to train local Girl Scouts to serve as exhibit facilitators. By working with local communities to select events and venues for pop-up events, the project hopes to bring cutting edge Earth and ocean science in creative new ways to underserved populations and inspire diverse audiences to explore further. This presentation will provide details of the project's goals, objectives and development and provide avenues to become involved.

    2014-10-01

    Full Text Available The Rutland Institute for Ethics at Clemson University seeks to encourage discussion on campus, in businesses, and in the community about how ethical decision-making can be the basis of both personal and professional success.  In the last 15 years, our fellows have, among other things, served as Co-PI’s on a wide range of grants, produced Responsible Conduct of Research training for science and engineering graduate students and faculty, managed the ethics curriculum at a medical school, and produced video lectures on ethical thinking for undergraduate Biology majors.  The crown jewel of our efforts to-date is our Ethics Across the Curriculum program, affectionately known as “ethics boot camp.”Each year, we bring faculty from all corners of the disciplinary spectrum together to show them how to have rich ethical discussions in their own classes with the students from their majors.  The program has been extremely successful and over the past 15 years has touched the lives of hundreds of faculty and thousands of students.  The purpose of this paper is to provide a very abbreviated version of the Rutland Ethics Across the Curriculum material to a wider audience of science educators.  It is our hope that this will motivate more faculty to introduce ethics into their classes as well as provide them the basic tools they will need to make this experience fruitful for all concerned.

    Thompson, R. M.; Mangin, K.

    2008-12-01

    Science classes for non-science majors present unique opportunities to create lifelong science aficionados and teach citizenship skills. Because no specific content is needed for future courses, subject matter can be selected to maximize interest and assignments can be focused on life skills such as science literacy instead of discipline-specific content mastery. Dinosaurs! is a very successful non-major science class with a minimum enrollment of 150 that is intended for sophomores. One of the goals of this class is to increase students' awareness of social issues, the political process, and opportunities for keeping up with science later in life. The main theme of this class is evolution. The bird-dinosaur link is the perfect vehicle for illustrating the process of science because the lines of evidence are many, convincing, and based on discoveries made throughout the last half-century and continuing to the present day. The course is also about evolution the social issue. The second writing assignment is an in-class affective writing based on a newspaper article about the Dover, PA court case. The primary purpose of this assignment is to create a comfort zone for those students with strong ideological biases against evolution by allowing them to express their views without being judged, and to instill tolerance and understanding in students at the other end of the spectrum. Another homework uses thomas.loc.gov, the government's public website providing information about all legislation introduced since the 93rd Congress and much more. The assignment highlights the difficulty of passing legislation and the factors that contribute to a given bill's legislative success or failure using the Paleontological Resources Preservation Act, S320. Details of these assignments and others designed to achieve the goals stated above will be presented. A very different undergraduate program, Marine Discovery, offers science majors the opportunity to earn upper division science

    As states begin to review their standards, some adopt or adapt the NGSS and others write their own, many basing these on the Framework for K-12 Science Education. Both the NGSS and the Frameworks have an increased emphasis on Earth Science but many high school teachers are being asked to teach these standards in traditional Biology, Chemistry and Physics courses. At the Earth Educators Rendezvous, teachers, scientists, and science education researchers worked together to find the interconnections between the sciences using the NGSS and identified ways to reference the role of Earth Sciences in the other sciences during lectures, activities and laboratory assignments. Weaving Earth and Space sciences into the other curricular areas, the teams developed relevant problems for students to solve by focusing on using current issues, media stories, and community issues. These and other lessons and units of study will be presented along with other resources used by teachers to ensure students are gaining exposure and a deeper understanding of Earth and Space Science concepts.

  3. Serving California's Science and Governance Needs through Crisis-driven Collaborations

    Science.gov (United States)

    Bernacchi, L.

    2015-12-01

    Due to its magnitude, the ongoing drought in California (USA) serves as an experimental space for innovative resource management and will define responses to predicted widespread drought. Due to the magnitude of its effect on humans and natural ecosystems and the water resources on which they depend, governmental programs are granting support to scientifically-valid, locally-produced solutions to water scarcity. Concurrently, University of California Water (UC Water) Security and Sustainability Research Initiative is focused on strategic research to build the knowledge base for better water resources management. This paper examines how a team of transdisciplinary scientists are engaged in water governance and information, providing examples of actionable research successfully implemented by decision makers. From a sociology of science perspective, UC Water scientists were interviewed about their engagement practices with California water decision makers. Their "co-production of knowledge" relationships produce effective responses to climatic, landcover and population changes by expanding from singularly information-based, unidirectional communication to governance-relevant, co-constructed knowledge and wisdom. This is accomplished by serving on decision making organizational boards and developing information in a productive format. The perceived crisis of California's drought is an important impetus in cross-sector collaborations, and in combination with governance and institution parameters, defines the inquiry and decision space. We conclude by describing a process of clear problem-solution definition made possible through transparent communication, salient and credible information, and relevant tools and techniques for interpreting scientific findings.

  4. Kilowatt-Class Fission Power Systems for Science and Human Precursor Missions

    Mason, Lee S.; Gibson, Marc Andrew; Poston, Dave

    2013-01-01

    Nuclear power provides an enabling capability for NASA missions that might otherwise be constrained by power availability, mission duration, or operational robustness. NASA and the Department of Energy (DOE) are developing fission power technology to serve a wide range of future space uses. Advantages include lower mass, longer life, and greater mission flexibility than competing power system options. Kilowatt-class fission systems, designated "Kilopower," were conceived to address the need for systems to fill the gap above the current 100-W-class radioisotope power systems being developed for science missions and below the typical 100-k We-class reactor power systems being developed for human exploration missions. This paper reviews the current fission technology project and examines some Kilopower concepts that could be used to support future science missions or human precursors.

    2016-10-01

    In this article we examine how bilingual students construe relations between everyday language and the language of science. Studies concerning bilingual students language use in science class have mainly been conducted in settings where both the teacher and the students speak the same minority language. In this study data was collected in a class consisting of students aged 13-14. All students had Turkish as their minority language, whereas the teacher's minority language was Bosnian. The class was observed when they were working with acids and bases. In addition, the students were interviewed in groups. They were asked about how they use their languages during science lessons and then asked to describe and explain scientific phenomena and processes that had been a part of the observed lessons. For the analysis, practical epistemology analysis and the theory of translanguaging were used. The results show how the students' everyday language repertoire may limit their possibilities to make meaning of science. In particular, the teacher's practice of facilitating and supporting students' understanding of science content by relating it to concrete examples took another direction since the everyday words he used were not a part of the students' language repertoire. The study also shows how the students used their minority language as a resource to translate words from Swedish to Turkish in order to proceed with the science activities. However, translating scientific concepts was problematic and led to the students' descriptions of the concepts not being in line with how they are viewed in science. Finally, the study also demonstrates how monolingual exams may limit bilingual students' achievements in science. The study contributes by presenting and discussing circumstances that need to be taken into consideration when planning and conducting science lessons in classes where the teacher and the student do not share the same minority language.

  6. Beyond Climate and Weather Science: Expanding the Forecasting Family to Serve Societal Needs

    Science.gov (United States)

    Barron, E. J.

    2009-05-01

    The ability to "anticipate" the future is what makes information from the Earth sciences valuable to society - whether it is the prediction of severe weather or the future availability of water resources in response to climate change. An improved ability to anticipate or forecast has the potential to serve society by simultaneously improving our ability to (1) promote economic vitality, (2) enable environmental stewardship, (3) protect life and property, as well as (4) improve our fundamental knowledge of the earth system. The potential is enormous, yet many appear ready to move quickly toward specific mitigation and adaptation strategies assuming that the science is settled. Five important weakness must be addressed first: (1) the formation of a true "climate services" function and capability, (2) the deliberate investment in expanding the family of forecasting elements to incorporate a broader array of environmental factors and impacts, (3) the investment in the sciences that connect climate to society, (4) a deliberate focus on the problems associated with scale, in particular the difference between the scale of predictive models and the scale associated with societal decisions, and (5) the evolution from climate services and model predictions to the equivalent of "environmental intelligence centers." The objective is to bring the discipline of forecasting to a broader array of environmental challenges. Assessments of the potential impacts of global climate change on societal sectors such as water, human health, and agriculture provide good examples of this challenge. We have the potential to move from a largely reactive mode in addressing adverse health outcomes, for example, to one in which the ties between climate, land cover, infectious disease vectors, and human health are used to forecast and predict adverse human health conditions. The potential exists for a revolution in forecasting, that entrains a much broader set of societal needs and solutions. The

  7. Developing Earth System Science Courses and Programs at Minority Serving Institutions

    Science.gov (United States)

    Johnson, D. R.; Jackson, C.; Ruzek, M.

    2004-12-01

    In the current NASA/USRA ESSE21 Program, emphasis is placed on the development of Earth System Science courses and degree offerings in Minority Serving Institutions (MSIs). Of the 18 colleges/universities being supported by NASA through USRA, 10 colleges/universities are MSIs. While there is recognition of the need for Earth system science courses, minors and degree programs by NASA and other agencies, within MSIs, a central challenge is how to provide a vision of the future opportunities in ESS and STEM disciplines that attracts and motivates students to these studies. Students need career guidance, role models and mentoring to encourage entry into STEM in general, and Earth system science in particular. Then there is the question of how to bring interested faculty together in institutions to form a critical mass that would forego the breadth and depth of disciplinary interests to undertake the development of multi/cross and interdisciplinary courses, minors and degree programs in ESS. Within the ESSE21 Diversity Working Group, the question has been raised as to how will MSIs ever be mainstream participants in ESS without teaching and engaging in research in remote sensing, modeling of the Earth's climate system and other like endeavors. Two other related questions raised within the Working Group are what are the long-term objectives of MSI adoption of ESS and what course corrections are needed to make ESS viable at MSIs. Within these considerations there are unresolved questions concerning the need and availability of resources from NASA, other agencies and local institutions. Apart from these larger considerations, efforts are underway within the ESSE21 Program that provide for sharing of resources among participants, organization of and access to materials that already exist, online resources, course outlines and successful listings for online resources by topics for particular courses and subject areas.

  10. General Education Earth, Astronomy and Space Science College Courses Serve as a Vehicle for Improving Science Literacy in the United States.

    Prather, E.

    2011-10-01

    Every year approximately 500,000 undergraduate college students take a general education Earth, Astronomy and Space Science (EASS) course in the Unites States. For the majority of these students this will be their last physical science course in life. This population of students is incredibly important to the science literacy of the United States citizenry and to the success of the STEM career pipeline. These students represent future scientists, technologists, business leaders, politicians, journalists, historians, artists, and most importantly, policy makers, parents, voters, and teachers. A significant portion of these students are taught at minority serving institutions and community colleges and often are from underserved and underrepresented groups, such as women and minorities. Members of the Center for Astronomy Education (CAE) at the University of Arizona have been developing and conducting research on the effectiveness of instructional strategies and materials that are explicitly designed to challenge students' naïve ideas and intellectually engage their thinking at a deep level in the traditional lecture classroom. The results of this work show that dramatic improvement in student understanding can be made from increased use of interactive learning strategies. These improvements are shown to be independent of institution type or class size, but appear to be strongly influenced by the quality of the instructor's implementation. In addition, we find that the positive effects of interactive learning strategies apply equally to men and women, across ethnicities, for students with all levels of prior mathematical preparation and physical science course experience, independent of GPA, and regardless of primary language. These results powerfully illustrate that all students can benefit from the effective implementation of interactive learning strategies.

  11. Scientist Spotlight Homework Assignments Shift Students’ Stereotypes of Scientists and Enhance Science Identity in a Diverse Introductory Science Class

    Schinske, Jeffrey N.; Perkins, Heather; Snyder, Amanda; Wyer, Mary

    2016-01-01

    Research into science identity, stereotype threat, and possible selves suggests a lack of diverse representations of scientists could impede traditionally underserved students from persisting and succeeding in science. We evaluated a series of metacognitive homework assignments (“Scientist Spotlights”) that featured counterstereotypical examples of scientists in an introductory biology class at a diverse community college. Scientist Spotlights additionally served as tools for content coverage, as scientists were selected to match topics covered each week. We analyzed beginning- and end-of-course essays completed by students during each of five courses with Scientist Spotlights and two courses with equivalent homework assignments that lacked connections to the stories of diverse scientists. Students completing Scientist Spotlights shifted toward counterstereotypical descriptions of scientists and conveyed an enhanced ability to personally relate to scientists following the intervention. Longitudinal data suggested these shifts were maintained 6 months after the completion of the course. Analyses further uncovered correlations between these shifts, interest in science, and course grades. As Scientist Spotlights require very little class time and complement existing curricula, they represent a promising tool for enhancing science identity, shifting stereotypes, and connecting content to issues of equity and diversity in a broad range of STEM classrooms.

    To improve students' scientific literacy and their general perceptions of chemistry, I enacted critical chemistry education (CCE) in two "regular level" chemistry classes with a group of 25 students in a suburban, private high school as part of this study. CCE combined the efforts of critical science educators (Fusco & Calabrese Barton, 2001; Gilbert 2013) with the performance expectations of the Next Generation Science Standards (NGSS) (NGSS Lead States, 2013a) to critically transform the traditional chemistry curriculum at this setting. Essentially, CCE engages students in the critical exploration of socially situated chemistry content knowledge and requires them to demonstrate this knowledge through the practices of science. The purpose of this study was to gauge these students development of chemistry content knowledge, chemistry interest, and critical scientific literacy (CSL) as they engaged in CCE. CSL was a construct developed for this study that necessarily combined the National Research Center's (2012) definition of scientific literacy with a critical component. As such, CSL entailed demonstrating content knowledge through the practices of science as well as the ability to critically analyze the intersections between science content and socially relevant issues. A mixed methods, critical ethnographic approach framed the collection of data from open-ended questionnaires, focus group interviews, Likert surveys, pre- and post unit tests, and student artifacts. These data revealed three main findings: (1) students began to develop CSL in specific, significant ways working through the activities of CCE, (2) student participants of CCE developed a comparable level of chemistry content understanding to students who participated in a traditional chemistry curriculum, and (3) CCE developed a group of students' perceptions of interest in chemistry. In addition to being able to teach students discipline specific content knowledge, the implications of this study are

    2012-12-01

    At the University of California, San Diego, I teach a quarter-long, introductory Earth Science class titled "Volcanoes," which is, in essence, a functional class in volcanology designed specifically for non-majors. This large-format (enrollment ~ 85), lecture-based class provides students from an assortment of backgrounds an opportunity to acquire much-needed (and sometimes dreaded) area credits in science, while also serving as an introduction to the Earth Science major at UCSD (offered through Scripps Institution of Oceanography). The overall goal of the course is to provide students with a stimulating and exciting general science option that, using an inherently interesting topic, introduces them to the fundamentals of geoscience. A secondary goal is to promote general science and geoscience literacy among the general population of UCSD. Student evaluations of this course unequivocally indicate a high degree of learning and interest in the material. The majority of students in the class (>80%) are non-science majors and very few students (degree-seeking students. In addition, only a handful of students have typically had any form of geology class beyond high school level Earth Science. Consequently, there are challenges associated with teaching the class. Perhaps most significantly, students have very little background—background that is necessary for understanding the processes involved in volcanic eruptions. Second, many non-science students have built-in anxieties with respect to math and science, anxieties that must be considered when designing curriculum and syllabi. It is essential to provide the right balance of technical information while remaining in touch with the audience. My approach to the class involves a dynamic lecture format that incorporates a wide array of multimedia, analogue demonstrations of volcanic processes, and small-group discussions of topics and concepts. In addition to teaching about volcanoes—a fascinating subject in and of

    Schinske, Jeffrey N; Perkins, Heather; Snyder, Amanda; Wyer, Mary

    2016-01-01

    Research into science identity, stereotype threat, and possible selves suggests a lack of diverse representations of scientists could impede traditionally underserved students from persisting and succeeding in science. We evaluated a series of metacognitive homework assignments ("Scientist Spotlights") that featured counterstereotypical examples of scientists in an introductory biology class at a diverse community college. Scientist Spotlights additionally served as tools for content coverage, as scientists were selected to match topics covered each week. We analyzed beginning- and end-of-course essays completed by students during each of five courses with Scientist Spotlights and two courses with equivalent homework assignments that lacked connections to the stories of diverse scientists. Students completing Scientist Spotlights shifted toward counterstereotypical descriptions of scientists and conveyed an enhanced ability to personally relate to scientists following the intervention. Longitudinal data suggested these shifts were maintained 6 months after the completion of the course. Analyses further uncovered correlations between these shifts, interest in science, and course grades. As Scientist Spotlights require very little class time and complement existing curricula, they represent a promising tool for enhancing science identity, shifting stereotypes, and connecting content to issues of equity and diversity in a broad range of STEM classrooms. © 2016 J.

    Prothero, W. A.

    2008-12-01

    Scientists must have in-depth background knowledge of their subject area and know where current knowledge can be advanced. They perform experiments that gather data to test new or existing theories, present their findings at meetings, publish their results, critically review the results of others, and respond to the reviews of their own work. In the context of a course, these activities correspond to learning the background material by listening to lectures or reading a text, formulating a problem, exploring data using student friendly data access and plotting software, giving brief talks to classmates in a small class or lab setting, writing a science paper or lab report, reviewing the writing of their peers, and receiving feedback (and grades) from their instructors and/or peers. These activities can be supported using course management software and online resources. The "LearningWithData" software system allows solid Earth (focused on plate tectonics) data exploration and plotting. Ocean data access, display, and plotting are also supported. Background material is delivered using animations and slide show type displays. Students are accountable for their learning through included homework assignments. Lab and small group activities provide support for data exploration and interpretation. Writing is most efficiently implemented using the "Calibrated Peer Review" method. This methodology is available at http://cpr.molsci.ucla.edu/. These methods have been successfully implemented in a large oceanography class at UCSB.

  5. The ABCDEF Bundle: Science and Philosophy of How ICU Liberation Serves Patients and Families.

    Science.gov (United States)

    Ely, E Wesley

    2017-02-01

    Over the past 20 years, critical care has matured in a myriad of ways resulting in dramatically higher survival rates for our sickest patients. For millions of new survivors comes de novo suffering and disability called "the postintensive care syndrome." Patients with postintensive care syndrome are robbed of their normal cognitive, emotional, and physical capacity and cannot resume their previous life. The ICU Liberation Collaborative is a real-world quality improvement initiative being implemented across 76 ICUs designed to engage strategically the ABCDEF bundle through team- and evidence-based care. This article explains the science and philosophy of liberating ICU patients and families from harm that is both inherent to critical illness and iatrogenic. ICU liberation is an extensive program designed to facilitate the implementation of the pain, agitation, and delirium guidelines using the evidence-based ABCDEF bundle. Participating ICU teams adapt data from hundreds of peer-reviewed studies to operationalize a systematic and reliable methodology that shifts ICU culture from the harmful inertia of sedation and restraints to an animated ICU filled with patients who are awake, cognitively engaged, and mobile with family members engaged as partners with the ICU team at the bedside. In doing so, patients are "liberated" from iatrogenic aspects of care that threaten his or her sense of self-worth and human dignity. The goal of this 2017 plenary lecture at the 47th Society of Critical Care Medicine Congress is to provide clinical ICU teams a synthesis of the literature that led to the creation of ICU liberation philosophy and to explain how this patient- and family-centered, quality improvement program is novel, generalizable, and practice changing.

    Urban environments offer students interesting opportunities to explore and examine how human modified landscapes influence biodiversity, nutrient cycling, and water quality. Students demanding applied field experiences from their undergraduate environmental science (ENVS) programs can be well served in urban settings. Here, we present strategies for integrating urban areas into the undergraduate field experience. Urban locations provide an opportunity for a different type of local "field-work" than would otherwise be available. In the intro level undergraduate ENVS class, we use our campus, the surrounding neighborhood and city as well as a nearby National Park for field exercises. Here we share lesson plans for field activities that can be completed with incoming undergraduate students, and show how these activities help students gain quantitative and investigative competency.

  7. Construction and Validation of an Instrument to Measure Taiwanese Elementary Students' Attitudes toward Their Science Class

    Wang, Tzu-Ling; Berlin, Donna

    2010-12-01

    The main purpose of this study is to develop a valid and reliable instrument for measuring the attitudes toward science class of fourth- and fifth-grade students in an Asian school culture. Specifically, the development focused on three science attitude constructs-science enjoyment, science confidence, and importance of science as related to science class experiences. A total of 265 elementary school students in Taiwan responded to the instrument developed. Data analysis indicated that the instrument exhibited satisfactory validity and reliability with the Taiwan population used. The Cronbach's alpha coefficient was 0.93 for the entire instrument indicating a satisfactory level of internal consistency. However, both principal component analysis and parallel analysis showed that the three attitude scales were not unique and should be combined and used as a general "attitudes toward science class" scale. The analysis also showed that there were no gender or grade-level differences in students' overall attitudes toward science class.

  8. Interpreting the relationships between single gender science classes and girls' academic motivation and interest

    Johnson, Sonya L.

    The purpose of this study was to determine how and to what extent single gender science classes affect motivation to learn scientific concepts, interest in science, and college major intent among high school and middle school girls. This study was designed to determine whether students' motivation to learn science changes when they are placed in a single gender science class. The study also measured whether the students' level of interest in science and desire to major in science changes based on their enrollment in a single gender class. Finally, the study investigated the career and college major intentions of the sample population used in the study. Girls in single gender groupings engage in more academic risk taking and participate more than girls in coeducational classes. This benefit alone responds to reform efforts and supports the abolition of gender-based obstacles. Single gender grouping could help encourage more girls to take interest in majoring in science, a field that is considered to be masculine. By increasing students' interest in science while enrolled in single gender classes, students may become more motivated to learn science. This study was conducted using seven, eighth, ninth and tenth grade girls from single sex and coeducational science classes. The students participated in 2 surveys, the Science Motivational Survey and the Test of Science Related Attitudes, at the beginning of the semester and at the end of the semester. In respect to girls in high school single gender science classes, results were contrary to recent studies that state that girls who received science education in a single gender setting have an increase in motivation and attitude towards science. The results did show that middle school girls in single gender science classes did show an increase in motivation.

    The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) is the home of processing, archiving, and distribution services for NASA sounders: the present Aqua AIRS mission and the succeeding SNPP CrIS mission. The AIRS mission is entering its 15th year of global observations of the atmospheric state, including temperature and humidity profiles, outgoing longwave radiation, cloud properties, and trace gases. The GES DISC, in collaboration with the AIRS Project, released product from the version 6 algorithm in early 2013. Giovanni, a Web-based application developed by the GES DISC, provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data. Most important variables from version 6 AIRS product are available in Giovanni. We are developing a climatology product using 14-year AIRS retrievals. The study can be a good start for the long term climatology from NASA sounders: the AIRS and the succeeding CrIS. This presentation will show the impacts to the climatology product from different aggregation methods. The climatology can serve climate science and application communities in data visualization and analysis, which will be demonstrated using a variety of functions in version 4 Giovanni. The highlights of these functions include user-defined monthly and seasonal climatology, inter annual seasonal time series, anomaly analysis.

    Full Text Available Women from working class and some ethnic minority backgrounds continue to be underrepresented in science, particularly in areas such as physical sciences and engineering. Many find it difficult to see science as something that is “for them”, which then has implications for their learning and participation in science. In this paper, I discuss findings from a U.K.-based qualitative study with 15 working-class girls, aged 11 to 13, from diverse ethnic backgrounds. Data were collected over the course of one academic year, through interviews and discussion groups with the girls and interviews with their science teachers, and analysed through a post-structural gender lens. The paper foregrounds five science-identifying girls, who negotiated their identification and engagement with science through the following discursive strategies: (i rendering gender invisible, (ii drawing attention to the presence of women in science, (iii reframing “science people” as caring and nurturing, and (iv cultural discourses of desirability of science. The findings contribute to the understanding of how working class girls—who are often “othered” and constructed as “unintelligible” within the dominant discursive regime of prototypical science—find identification with science possible. The paper discusses the affordances and challenges of each discursive strategy.

  1. Science anxiety and social cognitive factors predicting STEM career aspirations of high school freshmen in general science class

    Science.gov (United States)

    Skells, Kristin Marie

    Extant data was used to consider the association between science anxiety, social cognitive factors and STEM career aspirations of high school freshmen in general science classes. An adapted model based on social cognitive career theory (SCCT) was used to consider these relationships, with science anxiety functioning as a barrier in the model. The study assessed the following research questions: (1) Do social cognitive variables relate in the expected way to STEM career aspirations based on SCCT for ninth graders taking general science classes? (2) Is there an association between science anxiety and outcomes and processes identified in the SCCT model for ninth graders taking general science classes? (3) Does gender moderate these relationships? Results indicated that support was found for many of the central tenants of the SCCT model. Science anxiety was associated with prior achievement, self-efficacy, and science interest, although it did not relate directly to STEM career goals. Gender was found to moderate only the relationship between prior achievement and science self-efficacy.

    Urban environments offer students interesting opportunities to explore and examine how human modified landscapes influence biodiversity, nutrient cycling, and water quality. Students demanding applied field experiences from their undergraduate environmental science (ENVS) programs can be well served in urban settings. Here, we present strategies for integrating urban areas into the undergraduate field experience. Urban locations provide an opportunity for a different type of local "field-work" than would otherwise be available. In the intro level undergraduate ENVS class, we use our campus, the surrounding neighborhood and city as well as a nearby National Park for field exercises. Activities include: assessing water quality from multiple sites, observing species composition and ecological succession using fallen logs, assessing biodiversity using biocubes and camera traps, investigating conservation strategies through the local zoo, and walking one mile transects through local urban ecosystems to observe and collect data on the animals, buildings, roads, litter and/or light sources in the surrounding area. These labs provide inspiration and hands on skills that students apply to their own self-selected projects at the end of the semester. In the second level majors class, we make use of our urban location to contrast water quality in parks and highly channelized urban streams, monitor populations of urban wildlife, and investigate the application of urban greening methods to reduce environmental impacts. Students spend labs immersed in streams and wetlands heavily impacted by the urban runoff their city generates to better understand the extent of human impact in an urban environment. Here we share lesson plans for field activities that can be completed with incoming undergraduate students, and show how these activities help students gain quantitative and investigative competency.

    If elementary teachers are to be comfortable teaching science, they must have positive pre-service experiences. A science methods class that is activity-based and student-centered, rather than lecture-based and teacher-centered, peaks their interest in science and alleviates their fears. Activities conducted by the students illustrate science concepts or integrate science with children`s literature books such as The Grouchy Ladybug. These activities are conducted by each student with the rest of the class and the professor acting as an elementary class. Each activity is then evaluated as to the science concept, what was done well, and how it could be improved. The students also relate how the activity would be integrated with other subjects such as social studies, art, math, and language arts. Student feedback indicates this method is enjoyable, educational, and valuable in preparing them to teach science. The {open_quotes}oohs{close_quotes} and {open_quotes}I didn`t know that!{close_quotes} during activities are positives, but students have also learned some science, lost most of their science anxiety, and will teach science with the confidence and enthusiasm that was lacking at the beginning of the course.

    Autonomous Underwater Vehicles (AUVs) are an increasingly important tool for oceanographic research. They routinely and cost effectively sample the water column at depths far beyond what humans are capable of visiting. However, control of these platforms has relied on fixed sequences for execution of pre-planned actions limiting their effectiveness for measuring dynamic and episodic ocean phenomenon. At the Monterey Bay Aquarium Research Institute (MBARI), we are developing an advanced Artificial Intelligence (AI) based control system to enable our AUV's to dynamically adapt to the environment by deliberating in-situ about mission plans while tracking onboard resource consumption, dealing with plan failures by allowing dynamic re-planning and being cognizant of vehicle health and safety in the course of executing science plans. Existing behavior-based approaches require an operator to script plans a priori while anticipating where and how the vehicle will transect the water column. While adequate for current needs to do routine pre-defined transects, it has limited flexibility in dealing with opportunistic science needs, is unable to deal with uncertainty in the oceanic environment and puts undue burden on the mission operators to manage complex interactions between behaviors. Our approach, informed by a decades worth of experience in intelligent control of NASA spacecraft, uses a constraint-based representation to manage mission goals, react to exogenous or endogenous failure conditions, respond to sensory feedback by using AI-based search techniques to sort thru a space of likely responses and picking one which is satisfies the completion of mission goals. The system encapsulates the long-standing notion of a sense-deliberate-act cycle at the heart of a control loop and reflects the goal-oriented nature of control allowing operators to specify abstract mission goals rather than detailed command sequences. To date we have tested T- REX (the Teleo

    The study aimed to find out the effectiveness of using Strategic Intervention Materials (SIMs) as an innovative teaching practice in managing large Grade Eight Science classes to raise the performance of the students in terms of science process skills development and mastery of science concepts. Utilizing experimental research design with two groups of participants, which were purposefully chosen, it was obtained that there existed a significant difference in the performance of the experimental and control groups based on actual class observation and written tests on science process skills with a p-value of 0.0360 in favor of the experimental class. Further, results of written pre-test and post-test on science concepts showed that the experimental group with the mean of 24.325 (SD =3.82) performed better than the control group with the mean of 20.58 (SD =4.94), with a registered p-value of 0.00039. Therefore, the use of SIMs significantly contributed to the mastery of science concepts and the development of science process skills. Based on the findings, the following recommendations are offered: 1. that grade eight science teachers should use or adopt the SIMs used in this study to improve their students' performance; 2. training-workshop on developing SIMs must be conducted to help teachers develop SIMs to be used in their classes; 3. school administrators must allocate funds for the development and reproduction of SIMs to be used by the students in their school; and 4. every division should have a repository of SIMs for easy access of the teachers in the entire division.

    Taneja, Anju

    Studies have shown an association between argumentative discourse in science class, better understanding of science concepts, and improved academic performance. However, there is lack of research on how argumentation can increase student motivation. This mixed methods concurrent nested study uses Bandura's construct of motivation and concepts of argumentation and formative feedback to understand how teachers orchestrate argumentation in science class and how it affects motivation. Qualitative data was collected through interviews of 4 grade-9 science teachers and through observing teacher-directed classroom discourse. Classroom observations allowed the researcher to record the rhythm of discourse by characterizing teacher and student speech as teacher presentation (TP), teacher guided authoritative discussion (AD), teacher guided dialogic discussion (DD), and student initiation (SI). The Student Motivation Towards Science Learning survey was administered to 67 students before and after a class in which argumentation was used. Analysis of interviews showed teachers collaborated to plan argumentation. Analysis of discourse identified the characteristics of argumentation and provided evidence of students' engagement in argumentation in a range of contexts. Student motivation scores were tested using Wilcoxon signed rank tests and Mann-Whitney U-tests, which showed no significant change. However, one construct of motivation---active learning strategy---significantly increased. Quantitative findings also indicate that teachers' use of multiple methods in teaching science can affect various constructs of students' motivation. This study promotes social change by providing teachers with insight about how to engage all students in argumentation.

  16. Multiple-Choice Exams: An Obstacle for Higher-Level Thinking in Introductory Science Classes

    Science.gov (United States)

    Stanger-Hall, Kathrin F.

    2012-01-01

    Learning science requires higher-level (critical) thinking skills that need to be practiced in science classes. This study tested the effect of exam format on critical-thinking skills. Multiple-choice (MC) testing is common in introductory science courses, and students in these classes tend to associate memorization with MC questions and may not see the need to modify their study strategies for critical thinking, because the MC exam format has not changed. To test the effect of exam format, I used two sections of an introductory biology class. One section was assessed with exams in the traditional MC format, the other section was assessed with both MC and constructed-response (CR) questions. The mixed exam format was correlated with significantly more cognitively active study behaviors and a significantly better performance on the cumulative final exam (after accounting for grade point average and gender). There was also less gender-bias in the CR answers. This suggests that the MC-only exam format indeed hinders critical thinking in introductory science classes. Introducing CR questions encouraged students to learn more and to be better critical thinkers and reduced gender bias. However, student resistance increased as students adjusted their perceptions of their own critical-thinking abilities. PMID:22949426

    2003-12-01

    Introductory Earth science courses are undergoing pedagogical changes in universities across the country and are focusing more than ever on the non-science majors. Increasing enrollment of non-science majors in these introductory Earth science courses demands a new look at what is being taught and how the content can be objectively chosen. Assessing the content and effectiveness of these courses requires a quantitative investigation of introductory Earth science topics and their relevance to current issues and concerns. Relevance of Earth science topics can be linked to improved students' attitude toward science and a deeper understanding of concepts. We have used the Internet based national news search-engine LexisNexis Academic Universe (http://www.lexisnexis.org/) to select the occurrence of Earth science terms over the last 12 months, five and ten years both regionally and nationally. This database of term occurrences is being used to examine how Earth sciences have evolved in the news through the last 10 years and is also compared with textbook contents and course syllabi from randomly selected introductory earth science courses across the nation. These data constitute the quantitative foundation for this study and are being used to evaluate the relevance of introductory earth science course content. The relevance of introductory course content and current real-world issues to student attitudes is a crucial factor when considering changes in course curricula and pedagogy. We have examined students' conception of the nature of science and attitudes towards science and learning science using a Likert-scale assessment instrument in the fall 2002 Geology 100 classes at Iowa State University. A pre-test and post-test were administered to see if the students' attitudes changed during the semester using as reference a control group comprised of geoscience undergraduate and graduate students, and faculty. The results of the attitude survey have been analyzed in terms

    2013-12-01

    STEM education at New Jersey City University increasingly focuses on experiential, student-centered learning. The Department of Geoscience/Geography plays a significant role in developing and implementing a new Urban Environmental Science Program. The program aims at graduating highly skilled, demographically diverse students (14 % African-American and 18% Hispanic) to be employed in high-growth Earth and Environmental Science career paths, both at a technical (e.g. B.S.) as well as an educational (K-12 grade) (e.g. B.A) level. The core program, including the Earth and Environmental Science curricula is guided by partners (e.g. USDA-NRCS). The program is highly interdisciplinary and 'hands-on', focusing upon the high-tech practical skills and knowledge demanded of science professionals in the 21st century. The focus of the curriculum is on improving environmental quality in northern NJ, centering upon our urban community in Jersey City and Hudson County. Our Department is moving towards a more earth system science approach to learning. Most of our courses (e.g., Earth Surface Processes, Sedimentology/Stratigraphy, Earth Materials, Essential Methods, Historical Geology) have hands-on laboratory and/or field components. Although some of our other courses do not have formal laboratory components, research modules of many such courses (Geochemistry, Urban Environmental Issues and Policy and Environmental Geology) involve strong field or laboratory studies. The department has a wide range of analytical and laboratory capacities including a portable XRF, bench-top XRD and ICP-MS. In spring 2013, Dr. Duzgoren-Aydin was awarded $277K in Higher Education Equipment Leasing Fund monies from the University in order to establish an Environmental Teaching and Research Laboratory. The addition of these funds will make it possible for the department to increase its instrumentation capacity by adding a mercury analyzer, Ion Chromatography and C-N-S analyzer, as well as updating

    Many papers have been written in recent years discussing the interdisciplinary and transdisciplinary aspects of soil science. Therefore, it would make sense that soil science courses would be taken by students in a wide array of academic majors. To investigate this, we collected data from eight different American universities on the declared academic majors of students enrolled in soil science courses over a 10 year time period (2004-2005 to 2013-2014 academic years). Data was collected for seven different classes taught at the undergraduate level: introduction to soil science, soil fertility, soil management, pedology, soil biology/microbiology, soil chemistry, and soil physics. Overall trends and trends for each class were evaluated. Generally, environmental science and crop science/horticulture/agronomy students were enrolled in soil science courses in the greatest numbers. Environmental science and engineering students showed rapid increases in enrollment over the 10 years of the study, while the number of crop science/ horticulture/ agronomy students declined. In the introduction to soil science classes, environmental science and crop science/ horticulture/ agronomy students were enrolled in the greatest numbers, while declared soil science majors only made up 6.6% of the average enrollment. The highest enrollments in soil fertility were crop science/ horticulture/ agronomy students and other agricultural students (all agricultural majors except crop science, horticulture, agronomy, or soil science). In both the soil management and pedology classes, environmental science and other agricultural students were the largest groups enrolled. Other agricultural students and students from other majors (all majors not otherwise expressly investigated) were the largest enrolled groups in soil biology/microbiology courses, and environmental science and soil science students were the largest enrolled groups in soil chemistry classes. Soil physics was the only class

  5. Effects of Single-Gender Middle School Classes on Science Achievement and Attitude

    Brooks, Tanisha

    Many girls continue to achieve below their male counterparts and portray negative attitudes towards science classes. Some school districts are using single-gender education as a way to shrink the gender gap in school achievement and science related attitude. The purpose of this study was to compare achievement and science-related attitudes of 7th grade girls in single-gender education to 7th grade girls in mixed-gender education. The theoretical base for this study included knowledge from brain-based learning and assimilation, accommodation and age factors of Piaget's theory of cognitive development. The 12-week study included 48 7th grade girls, 21 in the single-gender classroom and 14 in each mixed-gender classroom. This quantitative randomized posttest only control group design utilized the TerraNova Science Assessment and the Test of Science Related Attitudes. Analysis of Variance (ANOVA) was used to determine if significant differences existed in the achievement and attitudes of girls in single and mixed-gender science classes. ANOVA analyses revealed that the girls in the single-gender classroom showed a significantly higher achievement level when compared to girls in the mixed-gender classrooms. Results showed no significant difference in attitude between the two groups. The results of this study contribute to social change by raising awareness about gender issues in science achievement and attitude, addressing a deficiency in the single-gender science education literature, and assisting educational systems in decision making to address achievement gaps while moving toward adequate yearly progress and meeting the requirements of the No Child Left Behind Act of 2001.

    This study explored pre-service secondary science teachers' perceptions of classroom emotional climate in the context of the Bhutanese macro-social policy of Gross National Happiness. Drawing upon sociological perspectives of human emotions and using Interaction Ritual Theory this study investigated how pre-service science teachers may be supported in their professional development. It was a multi-method study involving video and audio recordings of teaching episodes supported by interviews and the researcher's diary. Students also registered their perceptions of the emotional climate of their classroom at 3-minute intervals using audience response technology. In this way, emotional events were identified for video analysis. The findings of this study highlighted that the activities pre-service teachers engaged in matter to them. Positive emotional climate was identified in activities involving students' presentations using video clips and models, coteaching, and interactive whole class discussions. Decreases in emotional climate were identified during formal lectures and when unprepared presenters led presentations. Emotions such as frustration and disappointment characterized classes with negative emotional climate. The enabling conditions to sustain a positive emotional climate are identified. Implications for sustaining macro-social policy about Gross National Happiness are considered in light of the climate that develops in science teacher education classes.

    Most interventions with "maker" technologies take place outside of school or out of core area classrooms. However, intervening in schools holds potential for reaching much larger numbers of students and the opportunity to shift instructional dynamics in classrooms. This paper shares one such intervention where electronic textiles (sewable circuits) were introduced into eighth grade science classes with the intent of exploring possible gains in student learning and motivation, particularly for underrepresented minorities. Using a quasi-experimental design, four classes engaged in a traditional circuitry unit while the other four classes undertook a new e-textile unit. Overall, students in both groups demonstrated significant learning gains on standard test items without significant differences between conditions. Significant differences appeared between groups' attitudes toward science after the units in ways that show increasing interest in science by students in the e-textile unit. In particular, they reported positive identity shifts pertaining to their perceptions of the beliefs of their friends, family, and teacher. Findings and prior research suggest that student-created e-textile designs provide opportunities for connections outside of the classroom with friends and family and may shift students' perceptions of their teacher's beliefs about them more positively.

    2011-01-01

    This paper describes a newly adapted instrument for measuring novice-to-expert-like perceptions about biology: the Colorado Learning Attitudes about Science Survey for Biology (CLASS-Bio). Consisting of 31 Likert-scale statements, CLASS-Bio probes a range of perceptions that vary between experts and novices, including enjoyment of the discipline, propensity to make connections to the real world, recognition of conceptual connections underlying knowledge, and problem-solving strategies. CLASS-Bio has been tested for response validity with both undergraduate students and experts (biology PhDs), allowing student responses to be directly compared with a consensus expert response. Use of CLASS-Bio to date suggests that introductory biology courses have the same challenges as introductory physics and chemistry courses: namely, students shift toward more novice-like perceptions following instruction. However, students in upper-division biology courses do not show the same novice-like shifts. CLASS-Bio can also be paired with other assessments to: 1) examine how student perceptions impact learning and conceptual understanding of biology, and 2) assess and evaluate how pedagogical techniques help students develop both expertise in problem solving and an expert-like appreciation of the nature of biology.

    Abstract Health disparities are an immense challenge to American society. Clinical and Translational Science Awards (CTSAs) housed within the National Center for Advancing Translational Science (NCATS) are designed to accelerate the translation of experimental findings into clinically meaningful practices and bring new therapies to the doorsteps of all patients. Research Centers at Minority Institutions (RCMI) program at the National Institute on Minority Health and Health Disparities (NIMHD) are designed to build capacity for biomedical research and training at minority serving institutions. The CTSA created a mechanism fostering formal collaborations between research intensive universities and minority serving institutions (MSI) supported by the RCMI program. These consortium‐level collaborations activate unique translational research approaches to reduce health disparities with credence to each academic institutions history and unique characteristics. Five formal partnerships between research intensive universities and MSI have formed as a result of the CTSA and RCMI programs. These partnerships present a multifocal approach; shifting cultural change and consciousness toward addressing health disparities, and training the next generation of minority scientists. This collaborative model is based on the respective strengths and contributions of the partnering institutions, allowing bidirectional interchange and leveraging NIH and institutional investments providing measurable benchmarks toward the elimination of health disparities.

    Directory of Open Access Journals (Sweden)

    Bruno Belhoste

    2012-02-01

    Full Text Available This paper deals with the relationship between science and education in historiography, questioning the separation between the two activities, and highlighting the role of education to scientific activity. First, it distinguishes the largely accepted needs of historical contextualization from the epistemological problem, related to the place of history education in the history of science. It defends that the history of science education is not foreign to the history of science. It criticizes Chevallard’s notion of didactic transposition for reinforcing the gap between scientific knowledge and teaching knowledge. Finally, it argues that the sciences are in permanent reconstruction and that scientific knowledge is not tied to socio-cultural contexts from which it emerged.

  12. Class-first analysis in a continuum: an approach to the complexities of schools, society, and insurgent science

    Valdiviezo, Laura Alicia

    2010-06-01

    This essay addresses Katherine Richardson Bruna's paper: Mexican Immigrant Transnational Social Capital and Class Transformation: Examining the Role of Peer Mediation in Insurgent Science, through five main points . First, I offer a comparison between the traditional analysis of classism in Latin America and Richardson Bruna's call for a class-first analysis in the North American social sciences where there has been a tendency to obviate the specific examination of class relations and class issues. Secondly, I discuss that a class-first analysis solely cannot suffice to depict the complex dimensions in the relations of schools and society. Thus, I suggest a continuum in the class-first analysis. Third, I argue that social constructions surrounding issues of language, ethnicity, and gender necessarily intersect with issues of class and that, in fact, those other constructions offer compatible epistemologies that aid in representing the complexity of social and institutional practices in the capitalist society. Richardson Bruna's analysis of Augusto's interactions with his teacher and peers in the science class provides a fourth point of discussion in this essay. As a final point in my response I discuss Richardson Bruna's idea of making accessible class-first analysis knowledge to educators and especially to science teachers.

  13. Science serving people. IAEA-supported projects are helping countries apply the right tools to fight food, health, and water problems

    International Nuclear Information System (INIS)

    2002-01-01

    A new booklet 'Science Serving People' features stories about how IAEA-supported projects are making a difference in many poorer countries. The stories describe applications of nuclear science and technology that are being used through technical cooperation channels to overcome challenges of water scarcity, food shortage, malnutrition, malaria, environmental degradation and many other problems. They also illustrate how the complementary development, safety, and security initiatives of the IAEA are fostering atoms for peace in the developing world. Extreme poverty and deprivation remain a problem of monumental proportions at the dawn of the 21st century, notes IAEA Director General Mohamed ElBaradei in the booklet's Introduction. Through effective partnerships, collaborative research, and strategic direction, the IAEA is contributing to global efforts to help the poor. IAEA programmes have entered an important phase, he said, in which scientific contributions to Member States are yielding very sizeable human benefits. It's clear that science and technology must be better mobilized to meet the needs of the poor, emphasizes Jeffrey Sachs, Director of the Earth Institute at Columbia University, USA, and Special Advisor to UN Secretary-General Kofi Annan. The UN agencies, such as the IAEA, have a great role to play, he says in the booklet's Foreword. This is especially so, he points out, if they act as a bridge between the activities of advanced- country and developing country scientific centres, and if they help to harness the advances of world science for the poor as well as the rich. The bottom line, he concludes, is that rich countries should expand support for those United Nations organizations that can help in solving the unique problems confronting the world's poorest peoples. The booklet features stories on managing water resources, promoting food security, focusing science on health problems, new tools for environmental management, and strengthening nuclear

    AGU and the American Geological Institute (AGI) released on 26 July an employment study of 180 Earth and space science Ph.D. recipients who received degrees from U.S. universities in 2003. The AGU/AGI survey asked graduates about their education and employment, efforts to find their first job after graduation, and experiences in graduate school. Key results from the study include: The vast majority (87%) of 2003 graduates found work in the Earth and space sciences, earning salaries commensurate with or slightly higher than 2001 and 2002 salary averages. Most (64%) graduates were employed within academia (including postdoctoral appointments), with the remainder in government (19%), industry (10%), and other (7%) sectors. Most graduates were positive about their employment situation and found that their work was challenging, relevant, and appropriate for someone with a Ph.D. The percentage of Ph.D. recipients accepting postdoctoral positions (58%) increased slightly from 2002. In contrast, the fields of physics and chemistry showed significant increases in postdoctoral appointments for Ph.D.s during the same time period. As in previous years, recipients of Ph.D.s in the Earth, atmospheric, and ocean sciences (median age of 32.7 years) are slightly older than Ph.D. recipients in most other natural sciences (except computer sciences), which is attributed to time taken off between undergraduate and graduate studies. Women in the Earth, atmospheric,and ocean sciences earned 33% of Ph.D.s in the class of 2003, surpassing the percentage of Ph.D.s earned by women in chemistry (32%) and well ahead of the percentage in computer sciences (20%), physics (19%), and engineering (17%). Participation of other underrepresented groups in the Earth, atmospheric, and ocean sciences remained extremely low.

    Full Text Available This study aimed at investigating the challenges class teachers face in the curriculum implementation and whether these challenges differ in relation to teachers’ gender, level of education, department they graduated from and teaching experience. For this purpose; a questionnaire was developed by the researcher. Items of the questionnaire were selected from the related literature and validated by a group of expert in the field. A pilot study was conducted to assess the clarity of the questionnaire items. The internal reliability of the final version of questionnaire was calculated by using Cronbach’s Alpha Formula and found be high (α=0.85. The participants of this research included 342 class teachers who were teaching 4th and 5th class in 57 different elementary schools in 2010-2011 academic years in Bingol and Diayrbakir cities. The results of the survey were considered by using SPSS packet program. In the analyzing of data obtained from this study, frequency, arithmetic average, t-test and variance analysis were used. From the obtained data, it was determined that the 4th and 5th class teachers encounter different problems in science and technology teaching program, especially in performance homework, sourcing and lesson time topics.

    Pierre-Louis, Fred

    The purpose of this study was to describe Markdale High School's change from separate college preparatory and general level classes to heterogeneously-grouped classes in English, mathematics, science, and social studies, with particular emphasis on the principal's leadership style, change process, and teacher concerns (Hall & Hord, 2006) experienced during this effort. The researcher used Hall and Hord's (2006) Concern-Based Adoption Model (CBAM) as a conceptual framework. Specifically, the researcher applied three elements of the CBAM model: (a) the Twelve Principles of Change, (b) the Change Facilitator Styles, and (c) the Stages of Concerns. Hall and Hord's framework served as a lens through which the researcher analyzed all data. The researcher used a mixed-method (qualitative and quantitative) approach to answer the four research questions. The participants completed three instruments: (a) the Stages of Concern Questionnaire (SoCQ), (b) the Principles of Change Survey, and (c) the Facilitator Style Survey. All three instruments were self-report, paper-pencil surveys. The sample included 72 faculty members who experienced the change over the past three years. Findings from the three data sources and the school principal's comments during debriefing are indicated for each research question and reported by unit of analysis. Respective to the research questions, the researcher concluded that: (1) Markdale High School accomplished the change by implementing both structural and instructional changes supporting to the change to heterogeneous grouping; (2) even though teachers had divergent opinions on the school principal's facilitation style, the principal thought of himself as an incrementalist and a practitioner of differentiated facilitation styles; (3) while half of the faculty felt that they received formal training on heterogeneous grouping, (4) half felt that they did not have a choice in the decision-making process as it occurred with college preparatory and

    The United States Patent Office of the 1850s offers a rare opportunity to analyze the early gendering of science. In its crowded rooms, would-be scientists shared a workplace with women earning equal pay for equal work. Scientific men worked as patent examiners, claiming this new occupation as scientific in opposition to those seeking to separate science and technology. At the same time, in an unprecedented and ultimately unsuccessful experiment, female clerks were hired to work alongside male clerks. This article examines the controversies surrounding these workers through the lens of manners and deportment. In the unique context of a workplace combining scientific men and working ladies, office behavior revealed the deep assumption that the emerging American scientist was male and middle class.

    Michigan Science Teaching and Assessment Reform (Mi-STAR) is developing an NGSS-aligned middle school curriculum and associated teacher professional learning program in which science is taught and learned as an integrated body of knowledge that can be applied to address societal issues. With the generous support of the Herbert H. and Grace A. Dow Foundation, Mi-STAR has released several pilot-tested units through the Mi-STAR curriculum portal at mi-star.mtu.edu. Each of these units focuses on an ongoing `Unit Challenge' investigation that integrates STEM content across disciplinary boundaries, stimulates interest, and engages students in using scientific practices to address 21st century challenges. Each Mi-STAR unit is connected to a Unifying NGSS Crosscutting Concept (CCC) that allows students to recognize the concepts that are related to the phenomena or problems under investigation. In the 6th grade, students begin with an exploration of the CCC Systems and System Models. Through repeated applications across units, students refine their understanding of what a system is and how to model a complex Earth system. An example 6th grade unit entitled "Water on the Move: The Water Cycle," provides an example of how Mi-STAR approaches the use of Unifying CCCs and Unit Challenges to enhance middle school students' understanding of the interconnections of Earth system processes and human activities. Throughout the unit, students use a series of hands-on explorations and simulations to explore the hydrologic cycle and how human activity can alter Earth systems. Students develop new knowledge through repeated interactions with the Unit Challenge, which requires development of system models and construction of evidence-based arguments related to flooding problems in a local community. Students have the opportunity to make predictions about how proposed land-use management practices (e.g. development of a skate-park, rain garden, soccer field, etc.) can alter the earth

  19. Perceptions and attitudes of formative assessments in middle-school science classes

    Chauncey, Penny Denyse

    No Child Left Behind mandates utilizing summative assessment to measure schools' effectiveness. The problem is that summative assessment measures students' knowledge without depth of understanding. The goal of public education, however, is to prepare students to think critically at higher levels. The purpose of this study was to examine any difference between formative assessment incorporated in instruction as opposed to the usual, more summative methods in terms of attitudes and academic achievement of middle-school science students. Maslow's theory emphasizes that individuals must have basic needs met before they can advance to higher levels. Formative assessment enables students to master one level at a time. The research questions focused on whether statistically significant differences existed between classrooms using these two types of assessments on academic tests and an attitude survey. Using a quantitative quasi-experimental control-group design, data were obtained from a sample of 430 middle-school science students in 6 classes. One control and 2 experimental classes were assigned to each teacher. Results of the independent t tests revealed academic achievement was significantly greater for groups that utilized formative assessment. No significant difference in attitudes was noted. Recommendations include incorporating formative assessment results with the summative results. Findings from this study could contribute to positive social change by prompting educational stakeholders to examine local and state policies on curriculum as well as funding based on summative scores alone. Use of formative assessment can lead to improved academic success.

  20. How science teachers balance religion and evolution in the science classroom: A case study of science classes in a Florida Public School District

    Willems, Pierre Dominique

    The purpose of this case study was to research how science teachers balance both religion and evolution in the science classroom with as little controversy as possible. In this study I attempted to provide some insight on how teachers are currently teaching evolution in their science classes in light of the religious beliefs of the students as well as their own. The case study was conducted in a school district in Florida where I attempted to answer the following questions: (a) How do science teachers in the Florida School District (FSD) approach the religion--evolution issue in preparing students for a career in a field of science? (b) How do science teachers in the FSD reconcile the subject of evolution with the religious views of their students? (c) How do science teachers in the FSD reconcile their own religious views with the teaching of evolution? (d) How do science teachers in the FSD perceive the relationship between religion and science? The data was collected through interviews with two high school teachers, and one middle school teacher, by observing each participant teach, by collecting site documents and by administering an exploratory survey to student volunteers. Analysis was conducted by open coding which produced four themes from which the research questions were answered and the survey answers were counted to produce the percentages displayed in the tables in chapter four. The teachers avoided discussion on religiously oriented questions or statements by the students and did not reveal their own religious orientation. The topic of microevolution appeared to reduce stress in the classroom environment, as opposed to addressing macroevolution.

  1. Case Studies of Interactive Whole-Class Teaching in Primary Science: Communicative approach and pedagogic purposes

    2012-07-01

    By developing two case studies of expert teaching in action, this study aimed to develop knowledge of talk in whole-class teaching in UK primary science lessons and understand this in relation to both the teachers' interpretations and sociocultural theoretical frameworks. Lessons were observed and video-recorded and the teachers engaged in video-stimulated-reflective dialogue to capture participants' reflections upon their own pedagogic purposes and interactions in the classroom. The analytic framework was developed at three levels: sequence of lessons, lesson, and episode. For each episode, the 'communicative approach' and teaching purposes were recorded. Transcripts were developed for fine grain analysis of selected episodes and a quantitative analysis was undertaken of the use of communicative approaches. Findings exemplify how different communicative approaches were used by the case-study teachers for different pedagogical purposes at different points in the sequence of lessons, contributing to primary teachers' repertoire for planning and practice. The initial elicitation of children's ideas can be understood as pooling them to enhance multivoicedness and develop a shared resource for future dialogues. Whole-class talk can support univocality by rehearsing procedural knowledge and exploring the meanings of scientific terminology. Identifying salient features of phenomena in the context of the whole-class marks them as significant as shared knowledge but valuing other observations extends the multivoicedness of the discourse.

  2. Understanding social reproduction: The recursive nature of structure and agency within a science class

    Science.gov (United States)

    Seiler, Gale A.

    Schools and science classrooms within schools continue to contribute to social reproduction and to the disenfranchisement of inner city African American students though attempts have been made to remedy the situation through standards, high-stakes testing, and compensatory programs. Such reforms ignore the sociocultural, political, and economic contexts of the individual students in the schools they are impacting. They do not take into account the uniqueness and diversity of the learners in these settings and have not included the voices of the students. Another possibility was studied here; that of starting with the cultural capital of the learner rather than with external standards. In a non-required science course at a local high school two coteachers endeavored to enact a student-emergent curriculum as a way to foster student agency and to counteract the reproductive nature of schools. The class was examined as a field within multiple other fields. The dialectical relationship between structure and agency in the class was used to frame the analysis and the tension between them was examined at several levels through video and audio analysis. Structural and rational choice views of action were abandoned in favor of an understanding hinged upon strategies of action that actors construct from cultural toolkits in and through practice. In this setting the students and teachers co-constructed a class that can be described and characterized in certain ways yet contained many counter-examples and alternative characterizations. A continuum of successes and failures, agency and subjectivity can be found in the trends and counter-trends in the course. The contradictions were examined to portray the complexity of the interactions and the possibilities for agency within them.

    Professional development for teachers involved in the implementation of the Next Generation Science Standards (NGSS) will require a multifaceted approach combining curriculum development, understanding the nature of science, applications of engineering and technology, integrating reading and writing, and other pedagogical components. The Earth2Class Workshops (E2C) at the Lamont-Doherty Earth Observatory of Columbia University (LDEO) provides one model for creating effective training to meet the NGSS challenges. E2C has provided more than 135 workshops since 1998 that have brought together LDEO research scientists with classroom teachers and students from the New York metropolitan area and elsewhere. Each session provides teachers with the chance to learn first-hand about the wide range of investigations conducted at LDEO. This approach aligns strongly with the NGSS goals: mastery of the disciplinary core ideas, science and engineering practices, understanding the nature of science, and cross-cutting relationships. During workshops, participating teachers interact with scientists to gain understanding of what stimulated research questions, how scientists put together all the components of investigations, and ways in which results are disseminated. Networking among teachers often leads to developing lesson plans based on the science, as well as support for professional growth not always possible within the school setting. Through the E2C website www.earth2class.org, teachers and students not able to attend the live workshops can access archival versions of the sessions. The website also provides a wide variety of educational resources. These have proved to be valuable on a national basis, as evidenced by an average of more than 300,000 hits per month from thousands of site visitors. Participating researchers have found E2C to be an effective approach to provide broader outreach of their results. During the next couple of years, the E2C program will expand to provide

    Full Text Available Food-borne pathogens are the most important thing cause of illness and death in developing countries. Food safety is essential for central university kitchens because of the high number of meals served every day. These central university kitchen systems are of special interest as students are at relatively high-risk of developing serious complications from exposure to food bacterial contamination hazards. A total of 144 samples of cooked foods, collected in winter and summer 2015 from the restaurants of Tehran University of Medical Sciences, were studied to determine the microbiological quality of these products. Results were analyzed through SPSS 22.0 and t-test. According to coliform count, the highest rate of contamination was in Kebab (1.17×102 CFU/g and lowest was in fish (0.8×102 CFU/g and also the highest rate of contamination of Escherichia coli (E.coli was in Kebab (6 samples, and the lowest contamination level was in fish and in this regard no sample was reported to be positive. According to staphylococcus aureus, the highest contamination rate was in rice (0.97×102 CFU/g and lowest was in fish (0.63×102 CFU/g. Kebab had the highest contamination of ‎coliforms and staphylococcus aureus (S. aureus in summer. None of the tested samples was confirmed with respect to salmonella, clostridium perfringens and staphylococcus aureus. Among the foods served in the university restaurants, Kebab had the highest bacterial contamination and fishes the lowest. Improved methods of cooking and food processing, prevention of secondary bacterial contamination, continuous monitoring and surveillance of food processing are the most important measures to prevent food contamination.

    Full Text Available In recent years an increasing interest in the study of technological mediation in the educational processes at all levels of education. In this paper we communicate the characteristics found in current research on learning environments which integrate Information and Communication Technologies (ICTs into a science class. Analysis of the research uses Gowin’s heuristic technique V as a metacognitive strategy that allows the identification of the the relevant aspects of the research process. Reviewed and described were the different works selected to determine current trends in the study of teaching and learning processes using technology. It was possible to determine that the majority of the works analyzed study the aspects associated with the didactic efficacy of the use of ICTs, and only a few make reference to the interactive processes that emerge from learning activities.

  6. Understanding the experiences of a group of Yemeni students in an ESL science class

    Fradi, Gihan

    American classrooms are experiencing an influx of diverse language speaking students while for science educators the study of EBL students' learning in science classrooms is a relatively new field (Lee & Buxton, 2010). At the same time there is a growing emphasis on the importance of science practices (NGSS). This poses significant challenges for science educators who are enacting science curriculum that supports all students' learning. Supporting EBL students' academic achievement is significant because literacy is important for students' access to economic and social benefits that come with science literacy (Atwater, 1996). The purpose of this study was to examine the socio-linguistic challenges that a specific group of EBL students (Yemeni) faced and the extent to which such challenges affected their academic performance in science. These challenges are related to linguistic and cultural interactions, which can lead to conflicts between student and school, thereby interfering with the effectiveness of their education. This study also examined these students' and their science teacher's perspectives on strategies that can be used to facilitate their language acquisition during science class and help them become active participants in the school and classroom communities. The study used a qualitative interpretive research methodology and involved four Arab-American EBL students (two males and two females) from Yemen, who had been in the US for different periods of time. The amount of time these students had been in the US was important to examine differences in their acculturation and challenges they faced. Similarly, the use of female and male student participants was important to understand the impact of gender in the lived experiences of these students. The results of the study indicated that all the participants struggled with linguistic, social, and cultural aspects of their life in an American high school. These in turn led to a sense of being different

    2004-08-01

    Full Text Available Discourse is an educational practice through which students and teachers are related by a sequence of meanings that are expressed, interchanged, negociated and constructed in the dynamic of a class. In this article, we analize the discursive practices and the arguments that are stated during a Science class when the teacher and her students discuss about the concepts “drinkable water – pollute water” when they are dealing with Environmental Education contents. A qualitative research within the perspective of a case study, centred on discourse analysis, was performed. We examine the content, the resources and the structural features that are used by the teacher and the students in order to construct the arguments and to establish the ideas. Two different templates were detected: the teacher’s, is based on perceptions and operative concepts, while the student’s one is organized in order to seek a microscopic explanation. Nevertheless, negotiation between these two perspectives fails during the dialogic interaction.

    Mahoney, Melissa M.

    The increased demand for qualified STEM workers, necessitates addressing the bachelor's science, technology, engineering and mathematics (STEM) degree achievement among African Americans and other underrepresented populations. Using inquiry derived from Harper's (2010) Anti-Deficit Achievement Framework, this study sought to explore the factors that contribute to the successful degree completion of African American STEM students within a large comprehensive university system. Coding of the twelve semi-structured interviews revealed six major themes: a) K-12/precollege educational experiences, b) motivation to complete a STEM degree, c) systems of social support, d) extracurricular activities and out-of-class experiences, e) addressing stereotyping and discrimination, and f) faculty behaviors and dispositions. All themes were intertwined at each phase of participants' academic careers, thereby, highlighting the complexity of this population's experience and what is needed to address their low STEM degree attainment. Findings indicated that this student population benefits from positive, sustained faculty-student interactions, holistic STEM success programming, and genuine networks of social support. Furthermore, Harper's framework can be modified to explore the motivation of African American STEM students as well as the African American student's relationship with disability support services.

  9. Latent class analysis of diagnostic science assessment data using Bayesian networks

    Steedle, Jeffrey Thomas

    2008-10-01

    Diagnostic science assessments seek to draw inferences about student understanding by eliciting evidence about the mental models that underlie students' reasoning about physical systems. Measurement techniques for analyzing data from such assessments embody one of two contrasting assessment programs: learning progressions and facet-based assessments. Learning progressions assume that students have coherent theories that they apply systematically across different problem contexts. In contrast, the facet approach makes no such assumption, so students should not be expected to reason systematically across different problem contexts. A systematic comparison of these two approaches is of great practical value to assessment programs such as the National Assessment of Educational Progress as they seek to incorporate small clusters of related items in their tests for the purpose of measuring depth of understanding. This dissertation describes an investigation comparing learning progression and facet models. Data comprised student responses to small clusters of multiple-choice diagnostic science items focusing on narrow aspects of understanding of Newtonian mechanics. Latent class analysis was employed using Bayesian networks in order to model the relationship between students' science understanding and item responses. Separate models reflecting the assumptions of the learning progression and facet approaches were fit to the data. The technical qualities of inferences about student understanding resulting from the two models were compared in order to determine if either modeling approach was more appropriate. Specifically, models were compared on model-data fit, diagnostic reliability, diagnostic certainty, and predictive accuracy. In addition, the effects of test length were evaluated for both models in order to inform the number of items required to obtain adequately reliable latent class diagnoses. Lastly, changes in student understanding over time were studied with a

    The recent PCAST report (2012), Engage to Excel, calls for a major shift in instructional modes in introductory (geo)science courses by "replacing standard laboratory courses with discovery-based research courses". An increased emphasis is recommended to engage students in experiments with the possibility of true discovery and expanded use of scientific research courses in the first two years. To address this challenge, the On the Cutting Edge program convened a workshop of geoscience faculty to explore the many ways that true research experiences can be built into introductory geoscience courses. The workshop goals included: consideration of the opportunities, strategies and methods used to provide research experiences for students in lower division geoscience courses; examination of ways to develop students' "geoscience habits of mind" through participation in authentic research activities; exploration of ways that student research projects can be designed to contribute to public science literacy with applications to a range of issues facing humanity; and development of strategies to obtain funding for these research projects, to make these programs sustainable in departments and institutions, and to scale-up these programs so that all students may participate. Access to Earth data, information technology, lab and field-based instrumentation, and field experiences provide unprecedented opportunities for students to engage in authentic research at early stages in their careers. Early exposure to research experiences has proven to be effective in the recruitment of students to the geoscience disciplines, improved retention and persistence in degree programs, motivation for students to learn and increase self-efficacy, improved attitudes and values about science, and overall increased student success. Workshop outcomes include an online collection of tested research projects currently being used in geoscience classes, resources related to effective design

    Engaging students in active learning is linked to positive learning outcomes. This study aims to synthesise the peer-reviewed literature about 'active learning' in college science classroom settings. Using the methodology of an integrative literature review, 337 articles archived in the Educational Resources Information Center (ERIC) are examined. Four categories of in-class activities emerge: (i) individual non-polling activities, (ii) in-class polling activities, (iii) whole-class discussion or activities, and (iv) in-class group activities. Examining the collection of identified in-class activities through the lens of a theoretical framework informed by constructivism and social interdependence theory, we synthesise the reviewed literature to propose the active learning strategies (ALSs) model and the instructional decisions to enable active learning (IDEAL) theory. The ALS model characterises in-class activities in terms of the degrees to which they are designed to promote (i) peer interaction and (ii) social interdependence. The IDEAL theory includes the ALS model and provides a framework for conceptualising different levels of the general concept 'active learning' and how these levels connect to instructional decision-making about using in-class activities. The proposed ALS model and IDEAL theory can be utilised to inform instructional decision-making and future research about active learning in college science courses.

    2011-03-01

    The purpose of this study is to examine the effect of two strategies for negotiating the question for exploration during science inquiry on student achievement and teachers' perceptions. The study is set in the context of the Science Writing Heuristic. The first strategy (small group) consisted of each group of four students negotiating a question for inquiry with the teacher while the second strategy (whole class) consisted of the entire class negotiating a single question for inquiry with the teacher. The study utilized a mixed-method approach. A quasi-experimental repeated measures design was used to determine the effect of strategy on student achievement and semi-structured teacher interviews were used to probe the question of teacher perceptions of the two strategies. Teacher observations were conducted using the Reformed Teaching Observation Protocol (RTOP) to check for variation in implementation of the two strategies. Iowa Test of Basic Skills Science (ITBSS) (2005 and 2006) and teacher/researcher developed unit exams (pre and post) were used as student achievement measures. No statistically significant differences were found among students in the two treatment groups on the ITBSS or unit exams. RTOP observations suggest that teacher implementation was consistent across the two treatment strategies. Teachers disclosed personal preferences for the two strategies, indicating the whole class treatment was easier to manage (at least at the beginning of the school year) as students gained experience with science inquiry and the associated increased responsibility. Possible mechanisms linking the two strategies, negotiated questions, and student outcomes are discussed.

    A diverse workforce has been viewed for a long time as a healthy workforce. Traditionally however Soil Science has been seen as a male dominated field. The total number of female students enrolled showed increasing trends in all classes investigated during this study, but the percentage of female students showed a decline when analyzed by total students enrolled and also declined in four of the seven individual classes investigated. While both total enrollment and female enrollment increased during the study, male enrollment increased more rapidly than female enrollment. Soil biology/microbiology classes had a trend of more than 45% female enrollment throughout the study period, but many classes had less than 40% female enrollment, especially after the 2008-2009 academic year, and some hovered around only 35% female enrollment. The percentage of female soil science students had increased in the USA and Canada from 1992 to 2004 (Baveye et al., 2006) and Miller (2011) reported an increase in the number of female students at Iowa State University in the early 2000s. Therefore, the decrease in percentage of female soil science students found in our study was disappointing, even though absolute numbers of female students increased. It appears there is still a need to find ways to better market soil science coursework to female students. One possible way to accomplish this is to take advantage of the fact that many schools are now focusing efforts on STEM training specifically for females in grades 5-12, whereby science projects, after school programs, and mentorship can substantively influence females to pursue science-based fields in college. Another possibility is to promote the trends in female employment. As an example female employment within the Soil Science Division of the USDA-NRCS has increased over the same period. It should also be noted that the number of females in leadership roles has also increased. As a profession, soil science should look to take

    The project called Adotta scienza e arte nella tua classe ("Adopt Science and Art in your class"), on the interconnection between science and art, has been addressed to the Italian secondary middle and high school involving more than 200 teachers and about 2200 students. The main purpose of this project is to make the young students aware of the strong link between science and art is a unique cultural and interdisciplinary occasion. To reach this goal, the Adotta project asked students to produce an artwork inspired by the interpretation of a quotation among a hundred commented quotes by physicists, mathematicians, scientist, writers, artists, accompanied by an original short sentence written by students themselves. More than 1000 artworks have been produced and collected in two galleries on Facebook. From their analysis emerges the students' feeling about science, which is usually associated to human brain, based on mathematical laws and related to technological progress, but it is also a powerful tool that should be responsibly used. This project also valorizes teachers' role in scientific education through activities that encourage students to recognize science in every aspect of their lives.

    We apply The Tractor image modeling code to improve upon existing multi-band photometry for the Spitzer Extragalactic Representative Volume Survey (SERVS). SERVS consists of post-cryogenic Spitzer observations at 3.6 and 4.5 μ m over five well-studied deep fields spanning 18 deg{sup 2}. In concert with data from ground-based near-infrared (NIR) and optical surveys, SERVS aims to provide a census of the properties of massive galaxies out to z  ≈ 5. To accomplish this, we are using The Tractor to perform “forced photometry.” This technique employs prior measurements of source positions and surface brightness profiles from a high-resolution fiducial band from the VISTA Deep Extragalactic Observations survey to model and fit the fluxes at lower-resolution bands. We discuss our implementation of The Tractor over a square-degree test region within the XMM Large Scale Structure field with deep imaging in 12 NIR/optical bands. Our new multi-band source catalogs offer a number of advantages over traditional position-matched catalogs, including (1) consistent source cross-identification between bands, (2) de-blending of sources that are clearly resolved in the fiducial band but blended in the lower resolution SERVS data, (3) a higher source detection fraction in each band, (4) a larger number of candidate galaxies in the redshift range 5 <  z  < 6, and (5) a statistically significant improvement in the photometric redshift accuracy as evidenced by the significant decrease in the fraction of outliers compared to spectroscopic redshifts. Thus, forced photometry using The Tractor offers a means of improving the accuracy of multi-band extragalactic surveys designed for galaxy evolution studies. We will extend our application of this technique to the full SERVS footprint in the future.

    The "High school class for students with special abilities in physics" was founded in Nis, Serbia (www.pmf.ni.ac.yu/f_odeljenje) in 2003. The basic aim of this project has been introducing a broadened curriculum of physics, mathematics, computer science, as well as chemistry and biology. Now, six years after establishing of this specialized class, and 3 years after the previous report, we present analyses of the pupils' skills in solving rather problem oriented test, as PISA test, and compare their results with the results of pupils who study under standard curricula. More precisely results are compared to the progress results of the pupils in a standard Grammar School and the corresponding classes of the Mathematical Gymnasiums in Nis. Analysis of achievement data should clarify what are benefits of introducing in school system track for gifted students. Additionally, item analysis helps in understanding and improvement of learning strategies' efficacy. We make some conclusions and remarks that may be useful for the future work that aims to increase pupils' intrinsic and instrumental motivation for physics and sciences, as well as to increase the efficacy of teaching physics and science.

    Naugah, Jayantee; Watts, Mike

    2013-11-01

    Background: The population of Mauritius consists of 52% females and scientific literacy is seen to be of vital importance for all young people if they are to be sufficiently equipped to meet the challenges of a fast changing world. Previous research shows, however, that science is not popular among girls. This paper explores one of many reasons why few girls opt for science subjects after compulsory schooling. Purpose: This study investigated the approaches to teaching in four science classrooms in Mauritius, with particular emphases on the preferences of girls as they learn science. Sample: A total of 20 student interviews and 16 teacher interviews were conducted in four schools in Mauritius. The four mixed-faith schools comprised two all-girl schools (one state, one fee-paying), and two mixed-sex schools (one state, one fee-paying), within urban, suburban and rural situations. Design and method: 80 non-participant lessons were observed, of which 60 were science lessons while the remaining 20 non-science lessons were in economics, accounts and commerce. Group interviews with five pupils in each of the four schools were conducted and 16 individual interviews with teachers in the four schools gave an insight into the pedagogic approaches used for the teaching and learning of science. Results: Transmissive approaches to teaching, giving little opportunity for collaborative or activity-based learning, were found to be the most important factors in alienating the girls from science. Conclusions: There need to be radical changes in approaches to teaching to retain young girls' interest in the sciences.

  7. Doing, talking and writing science: A discourse analysis of the process of resemiotization in a middle school lab-based science class

    Science.gov (United States)

    Wright, Laura J.

    This study examines students' sense making practices in a middle school science class from a discourse analytic perspective. Using Mediated Discourse Analysis (MDA) (Scollon 1998, 2001) and interactional sociolinguistics (Gumperz 1999, 2001, Schiffrin 1994), my research seeks to enrich findings from recent sociocultural studies of science classrooms that focus on doing, talking and writing science (Roth 2005, Kress, et al. 2002, Halliday & Martin 1993, Lemke 1990). Within a middle school science classroom, these fundamental activities form a nexus of practice (Scollon 1998, 2001) basic to science literacy (AAAS 1989) and reflective of the work of practicing scientists. Moreover, students' engagement in these practices provides insight into the cultural production and reproduction of science and scientist. I first examine how the students' curriculum text encourages these three scientific practices and then trace students' uptake; that is, how they subsequently do, talk, and write science throughout the course of the unit. I argue that learning science with this curriculum unit requires students to resemiotize (Iedema 2001, 2003) first hand experience so they can represent their knowledge cohesively and coherently in evaluable forms. Ultimately, students must transform language from the curriculum text and their teacher into action in their laboratory activities and action in their laboratory activities into language. In addition, I show how students are apprenticed to the conventionalized practices and voices (Bakhtin 1986) of science (i.e. the scientific register), and how their figures of personhood (Agha 2005) reflect the development of their scientific identities. Overall, I argue that the microanalytic methods I use illuminate how students draw upon curricular resources to become scientifically literate and develop scientific identities.

    To better prepare first-year Department of Marine Science MSc students of the University of Southern Mississippi for their science careers, we plan to execute a semester-long Physical Oceanography laboratory class that exposes the enrolled students to all aspects of interdisciplinary research: writing a proposal, planning a cruise, collecting and analyzing data, and presenting their results. Although some of these aspects may be taught in any such class, the incorporation of all these aspects makes this class unique.The fieldwork will be conducted by boat in the Rigolets in Louisiana, a 13-km long tidal strait up to 1 km wide connecting the Mississippi Sound with Lake Pontchartrain. The students have the opportunity to collect ADCP, CTD, multibeam sonar, sediment and water samples.A second novel characteristic of this class is that the instructor partnered with the Lake Pontchartrain Basin Foundation, a not for profit environmental advocacy group. The foundation will give an hour-long seminar on the natural history of the study area and its environmental problems. This information provides context for the students' research proposals and allows them to formulate research questions and hypotheses that connect their research objectives to societally relevant issues, such as coastal erosion, salt water intrusion, and water quality. The proposal writing and cruise planning is done in the first month of the 3.5-month long semester. In the second month two surveys are conducted. The remainder of the semester is spent on analysis and reporting. Whenever possible we teach Matlab for the students to use in their data analysis. In this presentation, we will report on the successes and difficulties associated with teaching such a multi-faceted class.

    2005-10-01

    The purpose of this research effort was to examine Black male students' self-perceptions of academic ability and gifted potential in science. The purposeful sample consisted of nine Black males between the ages of 14 and 18 years. Four categories of self-perceptions of academic ability and gifted potential emerged from the data. These included: (a) gifted high achievers; (b) gifted could do better high achievers; (c) gifted could do better situational nonachievers; and (d) gifted could do better underachievers. Science teachers' influences that referenced participants' academic achievement pointed to validation. Participants' perceptions regarding how science teachers' influenced their academic performance focused on science teachers' content knowledge. Power dynamics germane to Black male participants' value or worth that directed their efforts in science learning environments are discussed. Implications are posited for science teaching, science education programs, and future research. This research endeavor was based on two premises. The first premise is that Black males' self-perceptions of academic ability affect their science academic achievement. The second premise is that, given parental, peer, and community influences, science teachers have considerable influence on students' self-perceptions of academic ability. However, the focus of this research was not on parental influences, peer influences, or any potential influences that participants' communities may have on their academic achievement.

    Hawarey, M. M.; Malkawi, M. I.

    2012-04-01

    A United Nations initiative for the Arab region that established and calculated National Intellectual Capital Index has shown that Jordan is the wealthiest Arab country in its National Human Capital Index (i.e. metrics: literacy rate, number of tertiary schools per capita, percentage of primary teachers with required qualifications, number of tertiary students per capita, cumulative tertiary graduates per capita, percentage of male grade 1 net intake, percentage of female grade 1 net intake) and National Market Capital Index (i.e. metrics: high-technology exports as a percentage of GDP, number of patents granted by USPTO per capita, number of meetings hosted per capita) despite its low ranking when it comes to National Financial Capital (i.e. metric: GDP per capita). The societal fabric in Jordan fully justifies this: the attention paid to education is extreme and sometimes is considered fanatic (e.g. marriage of a lot of couples needs to wait until both graduate from the university). Also, the low financial capital has forced a lot of people to become resourceful in order to provide decent living standard to their beloved ones. This reality is partially manifested in the sharp increase in the number of universities (i.e. 10 public and 20 private ones) relative to a population of around 6.5 million. Once in an engineering freshman classroom, it is totally up to the lecturers teaching science in private Jordanian universities to excel in their performance and find a way to inject the needed scientific concepts into the students' brains. For that, clips from movies that are relevant to the topics and truthful in their scientific essence have been tested (e.g. to explain the pressure on humans due to rapidly increasing "g" force, a clip from the movie "Armageddon" proved very helpful to Physics 101 students, and entertaining at the same time), plastic toys have also been tested to illustrate simple physical concepts to the same students (e.g. a set called The Junior

    Lado, Longun Moses

    This study examined the influence of a set of relevant independent variables on students' decision to major in math or science disciplines, on the one hand, or arts or humanities disciplines, on the other. The independent variables of interest in the study were students' attitudes toward science, their gender, their socioeconomic status, their age, and the strength and direction of parents' and peers' influences on their academic decisions. The study answered five research questions that concerned students' intention in math or science, the association between students' attitudes and their choice to major in math or science, the extent to which parents' and peers' perspectives influence students' choice of major, and the influence of a combination of relevant variables on students' choice of major. The scholarly context for the study was literature relating to students' attitudes toward science and math, their likelihood of taking courses or majoring in science or math and various conditions influencing their attitudes and actions with respect to enrollment in science or math disciplines. This literature suggested that students' experiences, their gender, parents' and peers' influence, their socio-economic status, teachers' treatment of them, school curricula, school culture, and other variables may influence students' attitudes toward science and math and their decision regarding the study of these subjects. The study used a questionnaire comprised of 28 items to elicit information from students. Based upon cluster sampling of secondary schools, the researcher surveyed 1000 students from 10 secondary schools and received 987 responses. The researcher used SPSS to analyze students' responses. Descriptive statistics, logistic regression, and multiple regression analyses to provide findings that address the study's research questions. The following are the major findings from the study: (1) The instrument used to measure students' attitudes toward science and

    2017-01-01

    Full Text Available We live in challenging times with a heightened sense of uncertainty and unpredictability. Climate change, with its impact on disruptive events as well as gradual trends, has been addressed in scientific studies and become increasingly important in policymaking. This rises up a great need on scientific integration and knowledge transformation. The Taiwan Integrated Research Programme on Climate Change Adaptation Technology (TaiCCAT is formed under this concern. Directing by the Ministry of Science and Technology (MOST, it carries a strong intention to explore and to conduct adequate knowledge of climate change and adaptation strategies for decision-making supports. The TaiCCAT highly recommends the approach of cross-disciplinary collaboration from environmental studies to adaptation governance. The result can therefore be more contributive to reflect the complexity of the changing world.

  1. Teaching Journalistic Texts in Science Classes: the Importance of Media Literacy

    Science.gov (United States)

    Ginosar, Avshalom; Tal, Tali

    2017-11-01

    This study employs a single framework for investigating both environmental journalistic texts published on news websites, and science teachers' choices of such texts for their teaching. We analyzed 188 environmental items published during 2 months in seven news websites to determine popularity of topics. Then, 64 science junior high school teachers responded to a closed questionnaire to identify their preferred topics for using in the classroom and patterns of using environmental news items. In a second, open-ended questionnaire, responded by 50 teachers, we investigated the teachers' media literacy in terms of identifying text types and writers of environmental news items. Good alignment was found between the published topics on the websites and teachers' choices, with somewhat different distribution of topics, which could be explained by curriculum requirements. Teachers' identification of text types and writer types was inaccurate, which implied that their media literacy is inadequate. We argue that media literacy is required for effective use of journalistic texts in science teaching.

    Abbas, Abdullah Othman

    1997-12-01

    This interpretive research set out to investigate the characteristics of an exemplary college science instructor who endeavors to improve teaching and learning in a physical science course for prospective teachers. The course was innovative in the sense that it was designed to meet the specific needs of prospective elementary teachers who needed to have models of how to teach science in a way that employed materials and small group activities. The central purpose for this study is to understand the metaphors that Mark (a pseudonym), the chemistry instructor in the course, used as referents to conceptualize his roles and frame actions and interactions in the classroom. Within the theoretical frame of constructivism, human cognitive interests, and co-participation theories, an ethnographic research design, described by Erickson (1986), Guba and Lincoln (1989), and Gallagher (1991), was employed in the study. The main sources of data for this study were field notes, transcript analysis of interviews with the instructor and students, and analyses of videotaped excerpts. Additional data sources, such as student journals and the results of students' responses to the University/Community College Student Questionnaire which was developed by a group science education researchers at Florida State University, were employed to maximize that the assertions I constructed were consistent with the variety of data. Data analyses and interpretation in the study focused on identifying the aspects which the instructor and the researcher might find useful in reflecting to understand what was happening and why that was happening in the classroom. The analysis reveals how the instructor used constructivism as a referent for his teaching and the learning of his students. To be consistent with his beliefs and goals that prospective teachers should enjoy their journey of learning chemistry, Mark, the driver in the journey, used the roles of controller, facilitator, learner, and entertainer

  3. Modern science in Portugal: the ‘class of the sphere’ in the college of Saint Anthony

    2017-05-01

    Full Text Available With the arrival of the Society of Jesus to Portugal in 1540, Jesuit schools were created by the Crown. The College of St. Anthony, in Lisbon, was the first Jesuit educational institution, created in 1553. We propose a discussion of the main objectives, characteristics and difficulties of the Jesuit religious order in the Portuguese territory, as well as a presentation of one of the most important classes of this College: the ‘Class of the Sphere’. The priests considered fundamental to teach issues related to mathematics and astronomy, because, through these disciplines, they addressed the theory and practice of items and concepts, such as the telescope, logarithms, equations, geometry and others. The curriculum of this college included, in addition to science and mathematics, subjects such as: Latin, Grammar, Humanities, Rhetoric, and Introduction to Moral Theology, Dogmatic Theology and Philosophy, considered only to teaching in the Portuguese context. Studying the College of St. Anthony helps us to understand how these innovations were considered in teaching, in the Jesuit case, in the temporal context of Portugal in the 16th century. We understand that the College, mainly by innovations, was essential to the development of science.

    Research into the process of learning, and learning astronomy, can be informative for the development of a course. Students are better able to incorporate and make sense of new ideas when they are aware of their own prior knowledge (Resnick et al. 1989; Confrey 1990), have the opportunity to develop explanations from their own experience in their own words (McDermott 1991; Prather et al. 2004), and benefit from peer instruction (Mazur 1997; Green 2003). Students in astronomy courses often have difficulty understanding many different concepts as a result of difficulties with spatial reasoning and a sense of scale. The Hands-on-Science program at UT Austin incorporates these research-based results into four guided-inquiry, integrated science courses (50 students each). They are aimed at pre-service K-5 teachers but are open to other majors as well. We find that Hands-on-Science students not only attain more favorable changes in attitude towards science, but they also outperform students in traditional lecture courses in content gains. Workshop Outcomes: Participants experienced a research-based, guided-inquiry lesson about the motion of objects in the sky and discussed the research methodology for assessing students in such a course.

  10. Setting the question for inquiry: The effects of whole class vs small group on student achievement in elementary science

    Science.gov (United States)

    Cavagnetto, Andy Roy

    This study was conducted to determine the effects of two different student-centered approaches to setting the question for inquiry. The first approach (whole class) consisted of students setting a single question for inquiry after which students worked in small groups during an investigation phase of the activity with all groups exploring the same question. The second approach (small group) consisted of each group of students setting a question resulting in numerous questions being explored per class. A mixed method quasi-experimental design was utilized. Two grade five teachers from a small rural school district in the Midwestern United States participated, each teaching two sections of science (approximately 25 students per section). Results indicate three major findings. Instructional approach (whole class vs. small group) did not effect student achievement in science or language arts. Observational data indicated the actions and skills teachers utilized to implement the approaches were similar. Specifically, the pedagogical skills of dialogical interaction (which was found to be influenced by teacher level of control of learning and teacher content knowledge) and effective rather than efficient use of time were identified as key factors in teachers' progression toward a student-centered, teacher-managed instructional approach. Unit exams along with qualitative and quantitative teacher observation data indicated that these factors do have an impact on student achievement. Specifically increased dialogical interaction in the forms of greater student voice, and increased cognitive demands placed on students by embedding and emphasizing science argument within the student inquiry corresponded to positive gains in student achievement. Additionally, teacher's perception of student abilities was also found to influence professional growth. Finally, allowing students to set the questions for inquiry and design the experiments impact the classroom environment as teacher

    One persistent difficulty many astronomy students face is the lack of 3- dimensional mental model of the systems being studied, in particular the Sun-Earth-Moon system. Students without such a mental model can have a very hard time conceptualizing the geometric relationships that cause, for example, the cycle of lunar phases or the pattern of seasons. The GeoWall is a recently developed and affordable projection mechanism for three-dimensional stereo visualization which is becoming a popular tool in classrooms and research labs for use in geology classes, but as yet very little work has been done involving the GeoWall for astronomy classes. We present results from a large study involving over 1000 students of varied backgrounds: some students were tested at the University of Texas at El Paso, a large public university on the US-Mexico border and other students were from the Florida Institute of Technology, a small, private, technical school in Melbourne Florida. We wrote a lecture tutorial-style lab to go along with a GeoWall 3D visual of the Earth-Moon system and tested the students before and after with several diagnostics. Students were given pre and post tests using the Lunar Phase Concept Inventory (LPCI) as well as a separate evaluation written specifically for this project. We found the lab useful for both populations of students, but not equally effective for all. We discuss reactions from the students and their improvement, as well as whether the students are able to correctly assess the usefullness of the project for their own learning.

  12. English language learners with learning disabilities interacting in a science class within an inclusion setting

    Ayala, Vivian Luz

    In today's schools there are by far more students identified with learning disabilities (LD) than with any other disability. The U.S. Department of Education in the year 1997--98 reported that there are 38.13% students with LD in our nations' schools (Smith, Polloway, Patton, & Dowdy, 2001; U.S. Department of Education, 1999). Of those, 1,198,200 are considered ELLs with LD (Baca & Cervantes. 1998). These figures which represent an increase evidence the need to provide these students with educational experiences geared to address both their academic and language needs (Ortiz, 1997; Ortiz, & Garcia, 1995). English language learners with LD must be provided with experiences in the least restrictive environment (LRE) and must be able to share the same kind of social and academic experiences as those students from the general population (Etscheidt & Bartlett, 1999; Lloyd, Kameenui, & Chard, 1997) The purpose of this research was to conduct a detailed qualitative study on classroom interactions to enhance the understanding of the science curriculum in order to foster the understanding of content and facilitate the acquisition of English as a second language (Cummins, 2000; Echevarria, Vogt, & Short, 2000). This study was grounded on the theories of socioconstructivism, second language acquisition, comprehensible input, and classroom interactions. The participants of the study were fourth and fifth grade ELLS with LD in a science elementary school bilingual inclusive setting. Data was collected through observations, semi-structured interviews (students and teacher), video and audio taping, field notes, document analysis, and the Classroom Observation Schedule (COS). The transcriptions of the video and audio tapes were coded to highlight emergent patterns on the type of interactions and language used by the participants. The findings of the study intend to provide information for teachers of ELLs with LD about the implications of using classroom interactions point to

  13. Integration of Place-Based Education Into Science Classes From Prekindergarten Through Grade 5

    Wade-Lyles, Terri A.

    In a large urban district in Ohio, 29.2% of Grade 5, 28.7% of Grade 8, and 45.7% of Grade 10 students passed the state test in science. School district administrators formed a community partnership with local science institutions in order to provide students with hands-on place-based learning experiences intended to improve science academic achievement in PK-Grade 5. The purpose of this qualitative program evaluation was to determine the level of implementation of that place-based program by examining the efficacy of the teachers' embedded professional development and their experiences with the training components. Bruner's theory of cognitive development was used to examine teachers' needs in facilitating the program. A stratified random sample of 659 PK-Grade 5 teachers from 73 district elementary schools was selected, and 57 teachers responded to an anonymous online survey of 5 open-ended questions. Data were analyzed using thematic analysis to identity factors that enhanced or impeded the implementation of place-based education programming based on their professional development. The key findings indicated that over half of the participants viewed resources as lacking, training as limited, and planning that is too time consuming, and complicated. Participants expressed the need for clarity regarding resources and more training on how to plan for and integrate the placed-based approach. The resulting project was an executive summary and interactive workshop for program stakeholders, such as administrators, teachers, and ultimately students, who would benefit from this project by improving the place-based program.

    2018-02-01

    Full Text Available This text aims to describe a methodological proposal to identify, classify, and organize the faunistic knowledge of students of rural schools. The research was conducted with twenty sixth graders from a rural school in the Department of Cundinamarca, Colombia. Through five types of activities, they expressed, in different ways, their knowledge about the animals of the region. The information collected was organized, categorized, and systematized in tables; these tables resulted from the analysis of the information the students provided. It is a possibility of school work that favors the recognition and valuation of the traditional and ancestral knowledge, and its incorporation to the dynamics of the teaching and learning of the Natural Sciences as a way to create “bridges” between that knowledge and the scholarly scientific knowledge. It is a proposal that, among other things, favors the development of more positive attitudes toward science itself, motivates students to ask questions, to recognize the importance of the cultural context, and to recognize themselves as part of a biocultural system.

  16. Effects of student choice on engagement and understanding in a junior high science class

    Science.gov (United States)

    Foreback, Laura Elizabeth

    The purpose of this study was to determine the effects of increasing individual student choice in assignments on student engagement and understanding of content. It was predicted that if students are empowered to choose learning activities based on individual readiness, learning style, and interests, they would be more engaged in the curriculum and consequently would develop deeper understanding of the material. During the 2009--2010 school year, I implemented differentiated instructional strategies that allowed for an increased degree of student choice in five sections of eighth grade science at DeWitt Junior High School. These strategies, including tiered lessons and student-led, project-based learning, were incorporated into the "Earth History and Geologic Time Scale" unit of instruction. The results of this study show that while offering students choices can be used as an effective motivational strategy, their academic performance was not increased compared to their performance during an instructional unit that did not offer choice.

    2013-08-01

    The conception of Global Learning Communities (GLCs) was researched to discover potential benefits of the use of online technologies that facilitated communication and scientific data sharing outside of the normal classroom setting. 1,419 students in 635 student groups began the instructional unit. Students represented the classrooms of 33 teachers from the USA, 6 from Thailand, 7 from Australia, and 4 from Germany. Data from an international environmental education project were analyzed to describe grades 7-9 student scientific writing in domestic US versus international-US classroom online partnerships. The development of an argument analytic and a research model of exploratory data analysis followed by statistical testing were used to discover and highlight different ways students used evidence to support their scientific claims about temperature variation at school sites and deep-sea hydrothermal vents. Findings show modest gains in the use of some evidentiary discourse components by US students in international online class partnerships compared to their US counterparts in domestic US partnerships. The analytic, research model, and online collaborative learning tools may be used in other large-scale studies and learning communities. Results provide insights about the benefits of using online technologies and promote the establishment of GLCs.

  18. A localized swarm of low-resource CubeSat-class spacecraft for auroral ionospheric science

    In interesting and dynamic auroral ionospheric plasmas, single-point in situ measurements are insufficient. Changes in measurements recorded from a single probe can be ascribed to either changes in position or to changes over time, and gradient scales can only be inferred. A localized array of sensors deployed as a low-resource swarm from a main deployer, can address these issues. We consider two aspects of designing such a swarm: (a) maintaining the localization in a low-cost manner, and (b) creating an extremely low-resource spacecraft by taking advantage of commercially available technologies. For a few-week low-altitude mission, STK (SatelliteToolKit) studies show that with proper deployment, an array of CubeSat-class spacecraft near 350 km altitude can regroup once per orbit to within a few 10s of km. Kepler's laws and Hill's equations allow us to put constraints on the capability of the deployer needed, in order to deploy the array with a minimal component of the ejection velocity along the orbital track. In order to keep the cost of each spacecraft low, we are exploring commercially available technologies such as Arduino controllers and video-game sensors. The Arduino on each payload will take in information from the sensors on the payload, and will send the information to a DNT-900MHz local area communications system. We show an example experiment measuring river flows on the Connecticut river, and discuss the design of our payload swarm.

    This study explores how to design a flipped classroom for a predental science course and evaluate its course through student self-assessment in order to provide practical implications for flipped learning in an undergraduate level. Second- and third-year predental students in the Seoul National University School of Dentistry enrolled in Biodiversity and Global Environment, a 15-week, three-credit course based on a flipped learning model. At the end of the course, the students were asked to rate their self-directed learning, attitude toward social media, discussion skills, learning readiness, and class satisfaction. Out of the 82 predental students, 61 (74.3%) answered the survey. Pearson correlation and multivariate regression analyses were employed to examine the relationship between the self-rated measurements and the performance scores. The majority of the students felt somewhat more prepared than the medium level before the class (mean score of 3.17 out of 5.00), whereas they expressed relatively low preference concerning social media use and attitude (mean score of 2.49). Thus, it was found that learning readiness was significantly associated with both discussion skills and class satisfaction. In particular, multivariate regression analysis confirmed that learning readiness had a significant influence on learning outcomes. This study offered insights into how to design a flipped learning course in terms of predental students' preference and their learning readiness. Although learning success in a flipped classroom depends on the students' self-perceived level of preparedness, much still remains to be achieved in order to apply social media benefits in a flipped learning context.

    Over the past quarter century, light-source user facilities have transformed research in areas ranging from gas-phase chemical dynamics to materials characterization. The ever-improving capabilities of these facilities have revolutionized our ability to study the electronic structure and dynamics of atoms, molecules, and even the most complex new materials, to understand catalytic reactions, to visualize magnetic domains, and to solve protein structures. Yet these outstanding facilities still have limitations well understood by their thousands of users. Accordingly, over the past several years, many proposals and conceptual designs for 'next-generation' x-ray light sources have been developed around the world. In order to survey the scientific problems that might be addressed specifically by those new light sources operating below a photon energy of about 3 keV and to identify the scientific requirements that should drive the design of such facilities, a workshop 'Science for a New Class of Soft X-Ray Light Sources' was held in Berkeley in October 2007. From an analysis of the most compelling scientific questions that could be identified and the experimental requirements for answering them, we set out to define, without regard to the specific technologies upon which they might be based, the capabilities such light sources would have to deliver in order to dramatically advance the state of research in the areas represented in the programs of the Department of Energy's Office of Basic Energy Sciences (BES).

    2014-02-01

    This study explored teachers' use of the Argumentation and Evaluation Intervention (AEI) and associated graphic organizer to enhance the performance of students in middle and secondary science classrooms. The results reported here are from the third year of a design study during which the procedures were developed in collaboration with teachers. A quasi-experimental pretest-posttest design with 8 experimental and 8 control teachers was used with a total of 282 students. An open-ended test assessed students' abilities to evaluate a scientific argument made in an article. The students were asked to identify the claim and its qualifiers, identify and evaluate the evidence given for the claim, examine the reasoning in support of the claim, consider counterarguments, and construct and explain a conclusion about the claim. The quality of students' responses was assessed using a scoring rubric for each step of the argumentation process. Findings indicated a significantly higher overall score and large effect size in favor of students who were instructed using the AEI compared to students who received traditional lecture-discussion instruction. Subgroup and subscale scores are also presented. Teacher satisfaction and student satisfaction and confidence levels are reported.

    The aim of this research is to identify the difficulties experienced by secondary school students (aged 15-16) with the critical reading of newspaper articles with scientific content. Two newspaper critical reading activities in relation to the study of various scientific contents were designed and carried out in two schools (61 students in total), one with a student population from a medium to high social and economic bracket and the other with students from a medium to low social and economic bracket. These activities were designed taking into account the phases of the reading process: before, during and after reading. In order to analyse the difficulties 'Elements of science critical reading' were identified on the basis of the 'Elements of reasoning' of Paul and Elder and the categories proposed by Bartz C.R.I.T.I.C. questionnaire and a scale was drawn up. The results show that the activities designed were useful in helping students to read critically. We also rated very positively the instrument created to assess the students' answers: the scale based on the performance indicators of Paul and Elder. This instrument enabled us to detect the aspects of critical thinking where students have the most difficulties: identifying the writer's purpose and looking for evidence in a text. It was also shown that the stance taken in the articles also had an influence on the results.

    In this study, we examine how bilingual students in elementary school use their languages and what this means for their meaning-making in science. The class was multilingual with students bilingual in different minority languages and the teacher monolingual in Swedish. The analysis is based on a pragmatic approach and the theory of translanguaging. The science content was electricity, and the teaching involved class instruction and hands-on activities in small groups. The findings of the study are divided into two categories, students' conversations with the teacher and student's conversations with each other. Since the class was multilingual, the class instruction was carried out in Swedish. Generally, when the conversations were characterised by an initiation, response and evaluation pattern, the students made meaning of the activities without any language limitations. However, when the students, during whole class instruction, were engaged in conversations where they had to argue, discuss and explain their ideas, their language repertoire in Swedish limited their possibilities to express themselves. During hands-on activities, students with the same minority language worked together and used both of their languages as resources. In some situations, the activities proceeded without any visible language limitations. In other situations, students' language repertoire limited their possibilities to make meaning of the activities despite being able to use both their languages. What the results mean for designing and conducting science lessons in a multilingual class is discussed.

  8. Science on the internet serving everyone?

    Full Text Available Editorial policies have changed gradually during the last decade. Before the advent of the internet and the digital formats, scientific information reached the scientific community through institutional libraries that received the periodicals by subscription. These subscriptions were expensive but the prices were compatible with the whole structure needed to produce, print and distribute paper periodicals. Other periodicals, generally of minor importance, could be distributed for free, and their costs were covered by annual membership fees from some association. Some received money from advertising and from scientific agencies to cover the expenses. The invention of the internet and the possibility it offered to distribute digital information seemed to be the perfect opportunity to democratize information, since it would make it possible, at least in theory, to reduce considerably the periodical production and distribution costs. In spite of this, electronic subscriptions are not cheaper, and many times are more expensive than the printed versions. Nowadays, most electronic journals are sold in separate papers and the articles cost around 40 US dollars each. Considering 12 volumes per year, containing 10 papers each, and the subscription would cost around 4,800 US dollars p.a. More recently the new vending method is the production of the so-called “open-access” papers which are in fact paid by the authors for the promess of many citations. From several hundreds to a few thousand dollars the author may make available on the web the results of his research for free download. This should be called “sponsored-access” instead. This policy benefits the journals and also a few countries, institutions or scientists who can afford it, since huge amounts of money are required. The poorest countries get excluded once more. Fortunately there are true “open-access” journals and those who collect symbolic fees to maintain themselves independent from exclusively volunteer work. Even better is the creation of scientific digital libraries like Scielo which is 15 years old and gathers today 12 countries from South and Central Americas plus Portugal and now South Africa. This kind of initiative should be recognized and be more valued by the scientific community, especially by ours that is still too attached to foreign indexes that seem to be world’s only scientific guides. This is the way to create a virtuous cycle that shall lead to a gradual enhancement in quality and to an efficient divulgation, and, more important: really free of the scientific work in Brazil and in other countries in a similar situation.

    Henderson, Jean Foster

    The purpose of this study was to assess the effect of classroom restructuring involving computer laboratories on student achievement and student attitudes toward computers and computer courses. The effects of the targeted student attributes of gender, previous programming experience, math background, and learning style were also examined. The open lab-based class structure consisted of a traditional lecture class with a separate, unscheduled lab component in which lab assignments were completed outside of class; the closed lab-based class structure integrated a lab component within the lecture class so that half the class was reserved for lecture and half the class was reserved for students to complete lab assignments by working cooperatively with each other and under the supervision and guidance of the instructor. The sample consisted of 71 students enrolled in four intact classes of Computer Science I during the fall and spring semesters of the 2006--2007 school year at two southern universities: two classes were held in the fall (one at each university) and two classes were held in the spring (one at each university). A counterbalanced repeated measures design was used in which all students experienced both class structures for half of each semester. The order of control and treatment was rotated among the four classes. All students received the same amount of class and instructor time. A multivariate analysis of variance (MANOVA) via a multiple regression strategy was used to test the study's hypotheses. Although the overall MANOVA model was statistically significant, independent follow-up univariate analyses relative to each dependent measure found that the only significant research factor was math background: Students whose mathematics background was at the level of Calculus I or higher had significantly higher student achievement than students whose mathematics background was less than Calculus I. The results suggest that classroom structures that

    Class relations have been proven to affect various aspects of social life, even in modern individualized societies. However, following claims on individualization and the so-called 'death of class' thesis, studying the subjective dimension of class - that is, the way individuals perceive of class relations and their own position within them - has gone out of style. We argue that even in equalized societies, subjective class perceptions may still influence attitudes and behaviour as they evolve to fit modern class relations. To explore the existence as well as structure and content of perceived social classes, this article investigates how people describe society and social groups in focus group discussions. We find that groups in different positions in terms of education and economy all tend to apply hierarchical class categories to describe Danish society, which is normally seen as one of the most equal societies and political systems in the world. In addition, we find that economic resources serve as a baseline for the hierarchical ordering, often supplemented with notions of education, lifestyle and/or occupational profile. Even though people are somewhat uncomfortable with the notion of class, their descriptions of Danish society and classes are surprisingly similar within and across groups. We conclude that not only do class relations matter; people are also highly aware of the existing classes and able to position themselves and others according to their notion of classes. © London School of Economics and Political Science 2017.

    The Interdisciplinary Teaching about Earth for a Sustainable Future (InTeGrate) community has developed extensive courses and modules designed for broad adoption into geoscience classrooms in diverse environments. I participated in a three-semester research project designed to test the efficacy of incorporating "high doses" (minimum 3 modules or 18 class periods) of InTeGrate materials into a course, in my case, an introductory environmental science class. InTeGrate materials were developed by groups of instructors from a range of institutions across the US. These materials include an emphasis on systems thinking, interdisciplinary approaches, and sustainability, and those themes are woven throughout the modules. The three semesters included a control in which no InTeGrate materials were used, a pilot in which InTeGrate materials were tested, and a treatment semesters in which tested materials were modified as needed and fully implemented into the course. Data were collected each semester on student attitudes using the InTeGrate Attitudinal Instrument (pre and post), a subset of Geoscience Literacy Exam questions (pre and post), and a series of assessments and essay exam questions (post only). Although results suggest that learning gains were mixed, changes in attitudes pre- and post-instruction were substantial. Changes in attitudes regarding the importance of sustainable employers, the frequency of self-reported individual sustainable actions, and motivation level for creating a sustainable society were observed in the control and treatment semesters, with the treatment semester showing the greatest gains. Importantly, one of the biggest differences between the control and treatment semesters is the reported impact that the course had on influencing students' sustainable behaviors. The treatment semester course impacted students' sustainable behaviors far more than the control semester.

In addition, it is considered one of the most efficient ways to disseminate theories, ideas, and facts. Many critics feel that lectures are an obsolete method to use when students need to perform hands-on activities, which is an everyday need in the study of medicine. This study evaluates students' perceptions regarding lecture quality in a new medical school. Methods: This was a cross-sectional study conducted of the medical students of Universiti Sultan Zainal Abidin. The study population was 468 preclinical medical students from years 1 and 2 of academic year 2012–2013. Data were collected using a validated instrument. There were six different sections of questions using a 5-point Likert scale. The data were then compiled and analyzed, using SPSS version 20. Results: The response rate was 73%. Among 341 respondents, 30% were male and 70% were female. Eighty-five percent of respondents agree or strongly agree that the lectures had met the criteria with regard to organization of lecture materials. Similarly, 97% of students agree or strongly agree that lecturers maintained adequate voices and gestures. Conclusion: Medical students are quite satisfied with the lecture classes and the lectures. However, further research is required to identify student-centered teaching and learning methods to promote active learning. Keywords: lecture, effectiveness, evaluation, undergraduate medical

    The project called 'Adotta scienza e arte nella tua classe' ('Adopt Science and Art in your class'), on the interconnection between science and art, has been addressed to the Italian secondary middle and high school involving more than 200 teachers and about 2200 students. The main purpose of this project is to make the young students aware of the strong link between science and art is a unique cultural and interdisciplinary occasion. To reach this goal, the Adotta project asked students to produce an artwork inspired by the interpretation of a quotation among a hundred commented quotes by physicists, mathematicians, scientist, writers, artists, accompanied by an original short sentence written by students themselves. More than 1000 artworks have been produced and collected in two galleries on Facebook. From their analysis emerges the students’ feeling about science, which is usually associated to human brain, based on mathematical laws and related to technological progress, but it is also a powerful tool that should be responsibly used. This project also valorizes teachers’ role in scientific education through activities that encourage students to recognize science in every aspect of their lives.

    By stimulating commerce and development at the bottom of the economic pyramid, multi-nationals could radically improve the lives of billions of people and help create a more stable, less dangerous world. Achieving this goal does not require MNCs to spearhead global social-development initiatives for charitable purposes. They need only act in their own self-interest. How? The authors lay out the business case for entering the world's poorest markets. Fully 65% of the world's population earns less than $2,000 per year--that's 4 billion people. But despite the vastness of this market, it remains largely untapped. The reluctance to invest is easy to understand, but it is, by and large, based on outdated assumptions of the developing world. While individual incomes may be low, the aggregate buying power of poor communities is actually quite large, representing a substantial market in many countries for what some might consider luxury goods like satellite television and phone services. Prices, and margins, are often much higher in poor neighborhoods than in their middle-class counterparts. And new technologies are already steadily reducing the effects of corruption, illiteracy, inadequate infrastructure, and other such barriers. Because these markets are in the earliest stages of economic development, revenue growth for multi-nationals entering them can be extremely rapid. MNCs can also lower costs, not only through low-cost labor but by transferring operating efficiencies and innovations developed to serve their existing operations. Certainly, succeeding in such markets requires MNCs to think creatively. The biggest change, though, has to come from executives: Unless business leaders confront their own preconceptions--particularly about the value of high-volume, low-margin businesses--companies are unlikely to master the challenges or reap the rewards of these developing markets.

    Is it possible to reach performance equality between boys and girls in a science class? Given the stereotypes targeting their groups in scientific domains, diagnostic contexts generally lower girls' performance and non-diagnostic contexts may harm boys' performance. The present study tested the effectiveness of a mastery-oriented assessment, allowing both boys and girls to perform at an optimal level in a science class. Participants were 120 boys and 72 girls (all high-school students). Participants attended a science lesson while expecting a performance-oriented assessment (i.e., an assessment designed to compare and select students), a mastery-oriented assessment (i.e., an assessment designed to help students in their learning), or no assessment of this lesson. In the mastery-oriented assessment condition, both boys and girls performed at a similarly high level, whereas the performance-oriented assessment condition reduced girls' performance and the no-assessment condition reduced boys' performance. One way to increase girls' performance on a science test without harming boys' performance is to present assessment as a tool for improving mastery rather than as a tool for comparing performances. © 2013 The British Psychological Society.

    2012-01-01

    This paper provides an in-depth, 'case study' style analysis of the experiences of two 13-year-old British Asian girls from a larger qualitative study investigating minority ethnic students' aspirations in science. Through the lens of identity as performativity and Bourdieu's notions of habitus and capital, the ways in which two girls engage with the field of science is examined. Samantha is British Indian and Fay is British Bangladeshi and they are both 'top set' students in science, but only one aspired to study triple science, while the other desired to be 'famous'. The experiences of the two girls are explicated in this paper, teasing out their experiences and constructions of science. It is argued that cultural discourses of family, peers and teacher expectations can shape students' perceptions of science and education.

    No Child Left Behind Act (NCLB) was signed into law in 2002 with the idea that all students, no matter the circumstances can learn and that highly qualified teachers should be present in every classrooms (United Stated Department of Education, 2011). The mandates of NCLB also forced states to begin measuring the progress of science proficiency beginning in 2007. The study determined the effects of teacher efficacy, the type of certification route taken by individuals, the number of content hours taken in the sciences, field-based experience and class size on middle school student achievement as measured by the 8th grade STAAR in a region located in South Texas. This data provides knowledge into the effect different teacher training methods have on secondary school science teacher efficacy in Texas and how it impacts student achievement. Additionally, the results of the study determined if traditional and alternative certification programs are equally effective in properly preparing science teachers for the classroom. The study described was a survey design comparing nonequivalent groups. The study utilized the Science Teaching Efficacy Belief Instrument (STEBI). A 25-item efficacy scale made up of two subscales, Personal Science Teaching Efficacy Belief (PSTE) and Science Teaching Outcome Expectancy (STOE) (Bayraktar, 2011). Once the survey was completed a 3-Way ANOVA, MANOVA, and Multiple Linear Regression were performed in SPSS to calculate the results. The results from the study indicated no significant difference between route of certification on student achievement, but a large effect size was reported, 17% of the variances in student achievement can be accounted for by route of certification. A MANOVA was conducted to assess the differences between number of science content hours on a linear combination of personal science teacher efficacy, science teaching outcome expectancy and total science teacher efficacy as measured by the STEBI. No significant

    With the growing elusiveness of the state apparatus in late modernity, military service is one of the last institutions to be clearly identified with the state, its ideologies and its policies. Therefore, negotiations between the military and its recruits produce acting subjects of citizenship with long-lasting consequences. Arguing that these negotiations are regulated by multi-level (civic, group, and individual) contracts, we explore the various meanings that these contracts obtain at the intersectionality of gender, class, and ethnicity; and examine how they shape the subjective experience of soldierhood and citizenship. More particularly, we analyse the meaning of military service in the retrospective life stories of Israeli Jewish women from various ethno-class backgrounds who served as army secretaries - a low-status, feminine gender-typed occupation within a hyper-masculine organization. Findings reveal that for women of the lower class, the organizing cultural schema of the multi-level contract is that of achieving respectability through military service, which means being included in the national collective. Conversely, for middle-class women, it is the sense of entitlement that shapes their contract with the military, which they expect to signify and maintain their privileged status. Thus, while for the lower class, the multi-level contract is about inclusion within the boundaries of the national collective, for the dominant groups, this contract is about reproducing social class hierarchies within national boundaries. © London School of Economics and Political Science 2014.

    This paper illustrates two psychometric methods, latent class analysis (LCA) and taxometric analysis (TA) using empirical data from research probing children's mental representation in science learning. LCA is used to obtain a typology based on observed variables and to further investigate how the encountered classes might be related to external variables, where the effectiveness of classification process and the unbiased estimations of parameters become the main concern. In the step-wise LCA, the class membership is assigned and subsequently its relationship with covariates is established. This leading-edge modeling approach suffers from severe downward-biased estimations. The illustration of LCA is focused on alternative bias correction approaches and demonstrates the effect of modal and proportional class-membership assignment along with BCH and ML correction procedures. The illustration of LCA is presented with three covariates, which are psychometric variables operationalizing formal reasoning, divergent thinking and field dependence-independence, respectively. Moreover, taxometric analysis, a method designed to detect the type of the latent structural model, categorical or dimensional, is introduced, along with the relevant basic concepts and tools. TA was applied complementarily in the same data sets to answer the fundamental hypothesis about children's naïve knowledge on the matters under study and it comprises an additional asset in building theory which is fundamental for educational practices. Taxometric analysis provided results that were ambiguous as far as the type of the latent structure. This finding initiates further discussion and sets a problematization within this framework rethinking fundamental assumptions and epistemological issues.

    The biotechnology industry plays a central role in the translation of nascent biomedical science into both products that offer material health benefits and creating capital growth. This study examines the relationship between the maturity of technologies in a characteristic life cycle and value creation by biotechnology companies. We examined the core technology, product development pipelines, and capitalization for a cohort of biotechnology companies that completed an IPO in 2000. Each of these companies was well financed and had core technologies on the leading edge of biological science. We found that companies with the least mature technologies had significantly higher valuations at IPO, but failed to develop products based on these technologies over the ensuing decade, and created less capital growth than companies with more mature technologies at IPO. The observation that this cohort of recently public biotechnology companies was not effective in creating value from nascent science suggests the need for new, evidence-based business strategies for translational science.

    Sudler, Dawn M.

    This study compared the differences in the Criterion-Referenced Competency Test (CRCT) mathematics and science achievement scores of boys and girls in Grade 7 at two urban middle schools. The data allowed the researcher to determine to what degree boys and girls in Grade 7 differ in their mathematics and science achievements within a single-gender environment versus a coeducational learning environment. The study compared any differences between boys and girls in Grade 7 within a single-gender environment in the subjects of mathematics and science, as measured by the CRCT assessments. The study also compared differences between boys and girls in Grade 7 within a coeducational environment in the subjects of mathematics and science, as measured by the CRCT assessments. Two middle schools were used within the study. One middle school was identified as a single-gender school (Middle School A); the other was identified as a coeducational school (Middle School B). This quantitative study applied the use of a descriptive research design. In addition, CRCT scores for the subjects of mathematics and science were taken during the spring of 2008 from both middle schools. Data were measured using descriptive statistics and independent t test calculations. The frequency statistics proceeded to compare each sample performance levels. The data were described in means, standard deviations, standard error means, frequency, and percentages. This method provided an excellent description of a sample scored on the spring 2008 CRCT mathematics and science assessments.

  1. The impact of an introductory college-level biology class on biology self-efficacy and attitude towards science

    Science.gov (United States)

    Thomas, Megan Elizabeth

    Self-efficacy theory was first introduced in a seminal article by Albert Bandura in 1977 entitled "Self-efficacy: Toward a unifying theory of behavioral change". Since its original introduction, self-efficacy has been a major focus of academic performance, anxiety, career development, and teacher retention research. Self-efficacy can be defined as the belief an individual possesses about their ability to perform a given task. Bandura proposed that self-efficacy should be measured at the highest level of specificity due to the fact that different people are efficacious in different areas. Interested in students' efficacy toward biology, Ebert-May, Baldwin, & Allred (1997) created and validated a survey to measure students' biology self-efficacy. Their survey was modeled after the guidelines for science literacy, and loaded to three sub-factors; methods of biology, generalization to other science courses, and application of the concepts. As self-efficacy theory has been related to effort expenditure and persistence (Bandura, 1977; 1997), one might think it would have some effect on students' attitudes toward the topic at hand. The current research investigated what changes in biology self-efficacy occurred after an introductory biology course with an inquiry based laboratory learning environment. In addition, changes in students' attitudes towards science were explored and how self-efficacy might affect them.

    Class network routing is implemented in a network such as a computer network comprising a plurality of parallel compute processors at nodes thereof. Class network routing allows a compute processor to broadcast a message to a range (one or more) of other compute processors in the computer network, such as processors in a column or a row. Normally this type of operation requires a separate message to be sent to each processor. With class network routing pursuant to the invention, a single message is sufficient, which generally reduces the total number of messages in the network as well as the latency to do a broadcast. Class network routing is also applied to dense matrix inversion algorithms on distributed memory parallel supercomputers with hardware class function (multicast) capability. This is achieved by exploiting the fact that the communication patterns of dense matrix inversion can be served by hardware class functions, which results in faster execution times.

    The purpose of this study was to examine the effects of English language proficiency and levels of scientific reasoning skills of Hispanic English language learners and native English language speaking students on their acquisition of science content knowledge as measured by a state-wide standardized science test. The researcher studied a group of high school Hispanic English language learners and native English language speaking students participating in Grade 10 science classes. The language proficiency of the students was to be measured through the use of the Test of English as a Foreign Language (TOEFL) instrument. A Classroom Test of Scientific Reasoning developed by Lawson (1978) was administered in either English or Spanish to the group of Hispanic English language learners and in English to the group of native English language-speaking students in order to determine their levels of scientific reasoning skills. The students' acquisition of science content knowledge was measured through the use of statewide-standardized science test developed by the State's Department of Education. This study suggests that the levels of English language proficiency appear to influence the acquisition of science content knowledge of Hispanic English language learners in the study. The results of the study also suggest that with regards to scientific reasoning skills, students that showed high levels or reflective reasoning skills for the most part performed better on the statewide-standardized science test than students with intuitive or transitional reasoning skills. This assertion was supported by the studies conducted by Lawson and his colleagues, which showed that high levels of reasoning or reflective reasoning skills are prerequisite for most high school science courses. The findings in this study imply that high order English language proficiency combined with high levels of reasoning skills enhances students' abilities to learn science content subject matter. This

    As the scientific community studies Mars remotely for signs of life and uses Martian meteorites as its only available samples, teachers, students, and the general public continue to ask, "How do we know these meteorites are from Mars?" This question sets the stage for a three-lesson instructional package Space Rocks Tell Their Secrets. Expanding on the short answer "It's the chemistry of the rock", students are introduced to the research that reveals the true identities of the rocks. Since few high school or beginning college students have the opportunity to participate in this level of research, a slide presentation introduces them to the labs, samples, and people involved with the research. As they work through the lessons and interpret real data, students realize that the research is an application of basic science concepts they should know, the electromagnetic spectrum and isotopes. They can understand the results without knowing how to do the research or operate the instruments.

    Didactic lecture is the oldest and most commonly used method of teaching. In addition, it is considered one of the most efficient ways to disseminate theories, ideas, and facts. Many critics feel that lectures are an obsolete method to use when students need to perform hands-on activities, which is an everyday need in the study of medicine. This study evaluates students' perceptions regarding lecture quality in a new medical school. This was a cross-sectional study conducted of the medical students of Universiti Sultan Zainal Abidin. The study population was 468 preclinical medical students from years 1 and 2 of academic year 2012-2013. Data were collected using a validated instrument. There were six different sections of questions using a 5-point Likert scale. The data were then compiled and analyzed, using SPSS version 20. The response rate was 73%. Among 341 respondents, 30% were male and 70% were female. Eighty-five percent of respondents agree or strongly agree that the lectures had met the criteria with regard to organization of lecture materials. Similarly, 97% of students agree or strongly agree that lecturers maintained adequate voices and gestures. Medical students are quite satisfied with the lecture classes and the lectures. However, further research is required to identify student-centered teaching and learning methods to promote active learning.

    The scientific community will access the public GLAST data through the website of the GLAST Science Support Center (GSSC). For most data products the GSSC website will link to the NASA High Energy Astrophysics Science Archive Research Center's (HEASARC) Browse interface, which will actually serve the data. For example, data from the GLAST Burst Monitor (GBM) from a given burst will be packaged together and accessible through Browse. However, the photon and event data produced by the Large Area Telescope (LAT), GLAST's primary instrument, will be distributed through a custom GSSC interface. These data will be collected over the LAT's large field-of-view, usually while the LAT is scanning the sky, and thus photons from a particular direction cannot be attributed to a single 'observation' in the traditional sense. Users will request all photons detected from a region on the sky over a specified time and energy range. Through its website the GSSC will also provide long and short term science timelines, spacecraft position and attitude histories, exposure maps and other scientific data products. The different data products provided by the GSSC will be described

    Full Text Available Food and drink catering service is almost as old as the civilization itself. Even though this vocation is a part of the catering activity, Serbian law does not foresee this contract section as personalized. Key legal sources for this kind of contract are business customs. Food and drink serving contract is a mixed-type contract and its legal nature is very interesting due to its complexity. Specific for this contract is the fact that it is not an ordinary service, but also an activity which requires a degree of culinary skills, knowledge of customs of other nations, as well as other skills. The very category of a good professional in business economy / hospitality industry is very dynamic, as it needs to be evaluated according to all given circumstances, which may be rather unpredictable. By considering the legal nature, but also the rights and obligations of the contracting parties, we tried to point to the questions that require a special attention. Legal sources that indirectly refer to food and drink serving contracts were taken into account. Apart from the Law on Obligatory Relations, we also considered here the Law on Tourism also pointing to the comparative law and jurisprudence.

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

    Science.gov (United States)

    Hogue, Barbara A.

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

    2008-01-01

    Full Text Available Dartmouth’s Critical Moments project is designed to promote discussions among faculty and graduate students about the retention of students, particularly women and minorities, in science, math, and engineering (SME disciplines. The first phase of the ongoing project has been the development of four case stories, which are fictionalized composites drawn from surveys and interviews of real Dartmouth students. The surveyed population was 125 students in general chemistry. Of the 77 who agreed to be interviewed, 61 reported having experienced a critical moment – i.e., a positive or negative event or time that had a significant impact on the student’s academic life. Leading critical moments were a poor grade on an exam; challenge from group work; excitement from an internship; and falling in love with a non-SME discipline from other coursework. Interviews of 13 students who had negative critical moments led to the development of case stories for: Antoinetta ’09, who had a disappointing group experience; Dalila ’08, who was poorly prepared; Greg ’09, who got in over his head in his first year; and Michelle ’08, who was shocked by her result in the first exam. The case stories are being discussed by graduate students, TA and faculty in various workshops at the Dartmouth Center for the Advancement of Learning.

    Pilot infrastructures are becoming prominent players in the Grid environment. One of the major advantages is represented by the reduced effort required by the user communities (also known as Virtual Organizations or VOs) due to the outsourcing of the Grid interfacing services, i.e. the pilot factory, to Grid experts. One such pilot factory, based on the glideinWMS pilot infrastructure, is being operated by the Open Science Grid at University of California San Diego (UCSD). This pilot factory is serving multiple VOs from several scientific domains. Currently the three major clients are the analysis operations of the HEP experiment CMS, the community VO HCC, which serves mostly math, biology and computer science users, and the structural biology VO NEBioGrid. The UCSD glidein factory allows the served VOs to use Grid resources distributed over 150 sites in North and South America, in Europe, and in Asia. This paper presents the steps taken to create a production quality pilot factory, together with the challenges encountered along the road.

Visual cues are important mediators of portion size and therefore technology-based aids may assist consumers when serving and estimating food portions. The current study evaluated the usability and impact on estimation error of standard food servings of a novel augmented reality food serving aid, ServAR. Participants were randomised into one of three groups: 1) no information/aid (control); 2) verbal information on standard serving sizes; or 3) ServAR, an aid which overlayed virtual food servings over a plate using a tablet computer. Participants were asked to estimate the standard serving sizes of nine foods (broccoli, carrots, cauliflower, green beans, kidney beans, potato, pasta, rice, and sweetcorn) using validated food replicas. Wilcoxon signed-rank tests compared median served weights of each food to reference standard serving size weights. Percentage error was used to compare the estimation of serving size accuracy between the three groups. All participants also performed a usability test using the ServAR tool to guide the serving of one randomly selected food. Ninety adults (78.9% female; a mean (95%CI) age 25.8 (24.9-26.7) years; BMI 24.2 (23.2-25.2) kg/m 2 ) completed the study. The median servings were significantly different to the reference portions for five foods in the ServAR group, compared to eight foods in the information only group and seven foods for the control group. The cumulative proportion of total estimations per group within ±10%, ±25% and ±50% of the reference portion was greater for those using ServAR (30.7, 65.2 and 90.7%; respectively), compared to the information only group (19.6, 47.4 and 77.4%) and control group (10.0, 33.7 and 68.9%). Participants generally found the ServAR tool easy to use and agreed that it showed potential to support optimal portion size selection. However, some refinements to the ServAR tool are required to improve the user experience. Use of the

    Extensive work has focused on the effects of nutrition label information on consumer behavior on the one hand, and on the effects of packaging graphics on the other hand. However, little work has examined how serving suggestion depictions - graphics relating to serving size - influence the quantity consumers serve themselves. The current work examines the prevalence of exaggerated serving size depictions on product packaging (study 1) and its effects on food serving in the context of cereal (study 2). Study 1 was an observational field survey of cereal packaging. Study 2 was a mixed experimental cross-sectional design conducted at a U.S. university, with 51 student participants. Study 1 coded 158 US breakfast cereals and compared the serving sizes depicted on the front of the box with the suggested serving size stated on the nutrition facts panel. Study 2 measured the amount of cereal poured from exaggerated or accurate serving size depictions. Study 1 compared average servings via t-tests. Study 2 used a mixed model with cereal type as the repeated measure and a compound symmetry covariance matrix. Study 1 demonstrated that portion size depictions on the front of 158 cereal boxes were 65.84% larger (221 vs. 134 calories) than the recommended portions on nutrition facts panels of those cereals. Study 2 showed that boxes that depicted exaggerated serving sizes led people to pour 20% more cereal compared to pouring from modified boxes that depicted a single-size portion of cereal matching suggested serving size. This was 45% over the suggested serving size. Biases in depicted serving size depicted on cereal packaging are prevalent in the marketplace. Such biases may lead to overserving, which may consequently lead to overeating. Companies should depict the recommended serving sizes, or otherwise indicate that the depicted portion represents an exaggerated serving size.

  19. What Types of Instructional Shifts Do Students Experience? Investigating Active Learning in Science, Technology, Engineering, and Math Classes across Key Transition Points from Middle School to the University Level

    Full Text Available Despite the need for a strong Science, Technology, Engineering, and Math (STEM workforce, there is a high attrition rate for students who intend to complete undergraduate majors in these disciplines. Students who leave STEM degree programs often cite uninspiring instruction in introductory courses, including traditional lecturing, as a reason. While undergraduate courses play a critical role in STEM retention, little is understood about the instructional transitions students encounter upon moving from secondary to post-secondary STEM courses. This study compares classroom observation data collected using the Classroom Observation Protocol for Undergraduate STEM from over 450 middle school, high school, introductory-level university, and advanced-level university classes across STEM disciplines. We find similarities between middle school and high school classroom instruction, which are characterized by a large proportion of time spent on active-learning instructional strategies, such as small-group activities and peer discussion. By contrast, introductory and advanced university instructors devote more time to instructor-centered teaching strategies, such as lecturing. These instructor-centered teaching strategies are present in classes regardless of class enrollment size, class period length, or whether or not the class includes a separate laboratory section. Middle school, high school, and university instructors were also surveyed about their views of what STEM instructional practices are most common at each educational level and asked to provide an explanation of those perceptions. Instructors from all levels struggled to predict the level of lecturing practices and often expressed uncertainty about what instruction looks like at levels other than their own. These findings suggest that more opportunities need to be created for instructors across multiple levels of the education system to share their active-learning teaching practices and

    A notational analysis of singles events at the French Open Grand Slam tournament was undertaken in 2005 and 2006 to characterize the game patterns and strategies of serve and serve-return and to determine their influence on the point issue on a clay court surface. One hundred sixteen men's singles matches were video analyzed. The flat serve (57.6%), particularly down the "T" location (50.3%), allowed servers to win significantly more points than the topspin (24.1%) and slice serves (18.3%). When the topspin was the first serve strategy, servers kept a high percentage of points won from the serve (52.4%). This strategy was essentially used on the second serve (91.6%) by playing the "T" location in the deuce court and the wide zone in the advantage court. Returns to the central zone allowed receivers to win more points (73.3% on first serve and 65.9% on second serve) than plays to external locations. The results highlight the high impact of the first shots of all opponents on the rally. Even on clay, the slowest court surface, serves and serve-returns remain the strokes that most influence the match results in modern tennis games.

  8. Women, race, and science: The academic experiences of twenty women of color with a passion for science

    Science.gov (United States)

    Johnson, Angela C.

    Women of color drop out of science at higher rates than other students. This study is an ethnographic examination of why this occurs and how women of color can be supported in studying science. Through participant observation in science classes, labs, and a program supporting high-achieving students of color, as well as interviews with minority women science students, the student identities celebrated by science departments, as well as those embraced by my informants, were uncovered. Cultural norms of science classes often differed from those of the women in the study. Only one identity---apprentice research scientist---was celebrated in science settings, although others were tolerated. The women tended to either embrace the apprentice research scientist identity, form an alternative science-oriented identity, or never form a satisfying science student identity. Women who were more racially marked were more likely to fall into the second and third groups. This study uncovered difficulties which women students of color faced more than other science students. In addition, it uncovered several seemingly neutral institutional features of science lectures and labs which actually served to discourage or marginalize women students of color. It revealed values held in common by the women in the study and how those characteristics (especially altruism and pride and pleasure in academic challenge) led them to study science. It also revealed strategies used by the most successful women science students, as well as by professors and programs most successful at supporting women of color in the study of science. Based on this study, increasing the participation of women of color in science holds the possibility of altering the basic values of science; however, institutional features and personal interactions within science departments tend to resist those changes, primarily by encouraging women of color to abandon their study of science.

    Full Text Available The essay explores some of the processes through which the ‘working class’ emerged both as a collective subjectivity and as a field of social science inquiry and public policies in 19th century France. Starting from the 1831 Canuts revolt, widely recognized as the stepping stone of the European workers’ movement, the first part retraces the process of the ‘making’ of a social and political subjectivity by stressing the relevance of its linguistic and discursive dimension. The second part examines the emergence of the empiric method of the modern social sciences through new strategies of inquiry on urban misery, which progressively focuses on the ‘working class’ and on labour conditions as a field of knowledge, rights, and governmental practices.

    The main fleet of transport packagings serving today the fuel cycle was born more than 20 years ago. Or was it they? The present paper will show that serving the fuel cycle by preparing tomorrow's logistics is actually an on-going process, rather than a rupture. We shall review the great packagings of the fuel cycle: In the front end, the major actors are the UF 4 , UF 6 , enriched UF 6 , UO 2 powders, fresh fuel packagings. In the back end of the fuel cycle, we find the dry transport casks of the TN-12, TN-17, TN-13, family and also the Excellox wet flasks. In the waste management, a whole fleet of containers, culminating in the TN Gemini, are available or being created. (author)

    Full Text Available Libraries and academic disciplines are experiencing a major transformation to the digital era. A challenge for libraries is to adapt and coordinate their transformation with differing rates and types of changes in teaching, research, and scholarly communication among the disciplines they serve. This paper argues libraries need to acknowledge the diversity of knowledge systems and adopt a strategy that requires collaboration between libraries and multiple communities of knowing in the development and provision of heterogeneous services.

    Full Text Available Background: Pre-contact information of servers' motion is important for receiving players in tennis. Objective: The aim of this study is to examine whether serving players use the same ball toss for kick serve (KS and slice serve (SS at two different directions of serves, from the receiver's view. Methods: 10 male right-handed professional tennis players with an average ATP ranking of 533 were videotaped from the receiver's view using a high-speed video camera (200 Hz. Firstly, they served SS and then KS from deuce court. After reaching 3 successful SS and 3 KS to the correct location, the same procedure followed from the ad court. Kinematic analysis was used to obtain the point of ball release, vertical toss peak and racquet-ball contact. Results: Even though the release point was found nearly in the same location, the vertical toss peak of KS was horizontally to the right compared to SS and the point of racquet ball-contact of KS was even more to the right by approximately 30 cm from the receiver's view. Similar findings were obtained from deuce court and ad court. Conclusions: We found differences in the ball toss execution between KS and SS. The serve toss can provide useful information for receiving players. Serving players should use the same toss for each type of serve to hide their intention.

  19. "I think I use them, but I'm not sure what each one is called": Integration of multiple literacies in secondary social studies and science classes

    Science.gov (United States)

    Lickteig, Amanda D.

    In the past, literacy was viewed solely as the basic, functional skills of reading and writing. However, with the New London Group's (1996) proposal of multiliteracies and the more recent push for a plurality of literacies (NCTE, 2011), teachers have been urged to expand their definitions of literacy. This qualitative study explores how secondary-level social studies and science teachers perceive literacies and identifies their instructional literacies practices. Data were collected through a pre- and post-questionnaire, three focus group sessions, classroom observations, field notes, and artifacts. This study solicited nearly one hundred secondary social studies and science teachers from three Midwestern school districts. Eight educators (four social studies and four science) participated in the study that took place in the spring of 2015. Furthermore, a generous grant from a local chapter of Phi Delta Kappa partially funded this research. After applying initial and holistic codes to the data, nine themes emerged: conventional, progressive, hesitant/emerging, collaborate, calibrate, perform, practice, interdisciplinary, and intradisciplinary. The nine themes were further classified by how they appeared in the data: dispositional themes, behavioral themes, and bridge themes. Throughout the data analysis, contemporary genre theory guided the study (Devitt, 2004). Descriptive codes, derived from contemporary genre theory, further revealed that the situational, social, historical, and individual aspects of genre influence teachers' pedagogical practices related to multiple literacies across disciplines. Therefore, the ways in which teachers perceived multiple literacies and implemented them into classroom instruction are multifaceted and vary depending on grade level, content area, and teaching location. However, teachers' dispositions regarding literacy move beyond a traditional mindset of functional reading and writing as they engage in professional learning

    The cold, dry, and stable air above the summits of the Antarctic plateau provides the best ground-based observing conditions from optical to sub-millimetre wavelengths to be found on the Earth. Pathfinder for an International Large Optical Telescope (PILOT) is a proposed 2m telescope, to be built at Dome C in Antarctica, able to exploit these conditions for conducting astronomy at optical and infrared wavelengths. While PILOT is intended as a pathfinder towards the construction of future grand-design facilities, it will also be able to undertake a range of fundamental science investigations in its own right. This paper provides the performance specifications for PILOT, including its instrumentation. It then describes the kinds of projects that it could best conduct. These range from planetary science to the search for other solar systems, from star formation within the Galaxy to the star formation history of the Universe, and from gravitational lensing caused by exo-planets to that produced by the cosmic web of dark matter. PILOT would be particularly powerful for wide-field imaging at infrared wavelengths, achieving near diffraction-limited performance with simple tip-tilt wavefront correction. PILOT would also be capable of near diffraction-limited performance in the optical wavebands, as well be able to open new wavebands for regular ground-based observation, in the mid-IR from 17 to 40μm and in the sub-millimetre at 200μm.

  2. An examination of single-gender and coeducational classes: Their impact on the academic achievement of middle school students enrolled in mathematics and science at selected schools in Georgia

    Elam, Jeanette H.

    The purpose of this study was to compare the academic performance of students enrolled in coeducational instruction and single-gender instruction. Within this framework, the researcher examined class type, gender, and racial/ethnicity using the sixth grade CRCT scores of selected students in the areas of mathematics and science. The fifth-grade mathematics and science scores for the same population were used to control for prior knowledge. This study examined the academic achievement of students based on class type, gender, and racial/ethnicity in relation to academic achievement. The study included the CRCT scores for mathematics and science of 6th-grade students at the middle school level who were tested during the 2007--2008 school year. Many studies conducted in the past have stressed females performed better in mathematics and science, while others have stated males performed better in the same areas. Yet, other studies have found conflicting results. A large Australian study (1996), compared the academic performance of students at single-gender and coeducational schools. The conclusion of this study indicated that both males and females who were educated in single-gender classrooms scored significantly higher than did males and females in coeducational classes. A study conducted by Graham Able (2003) documented superior academic performance of students in single-gender schools, after controlling for socioeconomic class and other variables. Able's most significant finding was that the advantage of single-gender schooling was greater for males in terms of academic results than for females. This directly contradicted the educational myth that males performed better in classrooms if females were present. The sample in this study consisted of CRCT scores for 304 sixth-grade students from four different middle schools. Due to the racial composition of the sample, the study only focused on black and white students. School 1 and School 2 involved single

    Many peaceful nuclear technologies today stand firmly established. They are being widely applied and accepted around the world in such fields as health care, food production, manufacturing, electricity generation, and environmental protection. Among the IAEA's 132 Member States, interest in constructively applying the tools of nuclear science and technology - especially outside the energy sector - remains high, although priorities, needs, and policies have changed over time. For the IAEA - whose specific mandate is to 'accelerate and enlarge the contribution of atomic energy to peace, health, and prosperity' - the changing and challenging global picture has strengthened efforts to enhance the contribution of nuclear science and technologies in key fields of human development. A multi-faceted programme of technical cooperation serves as the main vehicle for the transfer of nuclear science and technology to developing countries. The programme's emphasis is on supporting projects that respond to the priority needs of each country, produce an economic or social impact, and reflect the distinct advantages of nuclear technology over other approaches

    Why should students be trapped within the four walls of the classroom when there are a lot of ideas to have lessons led in the different way? I am not a fan of having lessons at school. For many students it is also boring to stay only at school, too. So I decided to organize workshops and trips to Universities or outdoors. I created KMO ( Discoverer's Club for Teenagers) at my school where students gave me some ideas and we started to make them real. I teach at school where students don't like science. I try hard to change their point of view about it. That's why I started to take parts in different competitions with my students. Last year we measured noise everywhere by the use of applications on a tablet to convince them that noise is very harmful for our body and us. We examined that the most harmful noises were at school's breaks, near the motorways and in the households. We also proved that acoustic screens, which were near the motorways, didn't protect us from noise. We measured that 30 meters from the screens the noise is the same as the motorway. We won the main prize for these measurements. We also got awards for calculating the costs of a car supplied by powered by a solar panel. We measured everything by computer. This year we decided to write an essay about trees and weather. We went to the forest and found the cut trees because we wanted to read the age of tree from the stump. I hadn't known earlier that we could read the weather from the tree's grain. We examined a lot of trees and we can tell that trees are good carriers of information about weather and natural disasters. I started studies safety education and I have a lot of ideas how to get my students interested in this subject that is similar to P.E., physics and chemistry, too. I hope that I will use my abilities from European Space Education Resource Office and GIFT workshop. I plan to use satellite and space to teach my students how they can check information about terrorism, floods or other

    Full Text Available Research has shown that outdoor educational interventions can lead to students' increased self-regulated motivational behavior. In this study, we searched into the satisfaction of basic psychological needs (BPN, i.e., autonomy support, the learners' experience of competence, and relatedness, both within the peer group and with their teachers, through outdoor learning. From 2014 to 2016, n = 281 students attended “research weeks” at a Student Science Lab in the Alpine National Park Berchtesgaden (Germany. The program is a curriculum-based one-week residential course, centered on a 2-day research expedition. Both before and after the course, students completed a composite questionnaire addressing BPN-satisfaction and overall motivational behavior in relation to the Self-Determination Index (SDI. At the latter time-point, students also reported on their experiences during the intervention. Questionnaire data was analyzed using a set of Bayesian General Linear Models with random effects. Those quantitative measures have been complemented by and contextualized with a set of qualitative survey methods. The results showed that the basic psychological needs influence the motivational behavior in both contexts equally, however on different scale levels. The basic needs satisfaction in the outdoor context is decisively higher than indoors. Moreover, the increment of competence-experience from the school context to the hands-on outdoor program appears to have the biggest impact to students' increased intrinsic motivation during the intervention. Increased autonomy support, student-teacher relations, and student-student relations have much less or no influence on the overall difference of motivational behavior. Gender does not influence the results. The contextualization partly supports those results and provide further explanation for the students' increased self-regulation in the outdoors. They add some explanatory thrust to the argument that outdoor

    Smith, Mary E.

    The Georgia State Board of Education has put in place requirements that high school students must meet in order to advance to a higher grade level and to achieve credits for graduation. Georgia requires all ninth, tenth, eleventh, and twelfth graders to take an end-of-course test after completing class time for academic core subjects. The student's final grade in the end-of-course test course will be calculated using the course grade as 85% and the end-of-course test score as 15%. The student must have a final course grade of 70 or above to pass the course and to earn credit toward graduation. Students in Georgia are required to take the Georgia High School Graduation Test. The tests consist of five parts, writing, math, science, social studies and language arts. Students must make a minimum score of 500 which indicates the student was proficient in mastering the objectives for that particular section of the test. Not all students finish high school in four years due to obstacles that occur. Tutorial sessions are provided for those that wish to participate. High schools may offer study skills classes for students that need extra help in focusing their attention on academic courses. Study skill courses provide the student with techniques that he or she may find useful in organizing thoughts and procedures that direct the student towards success.

    2014-10-01

    This article is based not only on the research literature but also on the extensive field experience of the authors in consulting with investigators, attorneys, and organizations on the prevention, investigation, prosecution, and civil litigation of molestation of children within or in connection with youth-serving organizations. Acquaintance molesters have often pursued careers or sought out paid or volunteer work with organizations through which they can meet children. To address the problem of such offenders, it is necessary for youth-serving organizations to recognize the diversity of sexual activity, the phenomena of "nice-guy" offenders and compliant child victims, and the grooming/seduction process, each of which is reviewed here. The four most important protection practices for organizations are screening; management, and supervision; response to suspicions, allegations, and complaints; and prevention and awareness programs. The authors recommend general approaches to each of these and describe the reasons many organizations resist implementing available preventive measures. © The Author(s) 2014.

    McCammon, William Gavin Lodge, Jr.

    Teachers should have access to new and innovative tools in order to engage and motivate their students in the classroom. This is especially important as many students view school as an antiquated and dull environment - which they must seemingly suffer through to advance. School need not be a dreaded environment. The use of music as a tool for learning can be employed by any teacher to create an engaging and exciting atmosphere where students actively participate and learn to value their classroom experience. Through this study, a product and process was developed that is now available for any 8th grade science teacher interested in using music to enhance their content. In this study 8th grade students (n=41) in a public school classroom actively interacted with modern songs created to enhance the teaching of chemistry. Data were collected and analyzed in order to determine the effects that the music treatment had on student achievement and motivation, compared to a control group (n=35). Current literature provides a foundation for the benefits for music listening and training, but academic research in the area of using music as a tool for teaching content was noticeably absent. This study identifies a new area of research called "Music-based Teaching" which results in increases in motivation for 8th grade students learning chemistry. The unintended results of the study are additionally significant as the teacher conducting the treatment experienced newfound enthusiasm, passion, and excitement for her profession.

    1997-01-01

    The utility no longer has protected status, and the traditional franchise concept is under attack. Exclusive rights once conveyed to the utilities are being denied and not just in the area of gas sales. Exclusive rights once conveyed to utilities will be denied in more areas. State by state, the utilities' franchise is being examined to see which, if any, of its provisions are necessary in a deregulated environment. Can the free market provide everything that's been provided for many years under monopolistic arrangements? Some of the most critical and difficult of these provisions concern the obligation to serve, which utilities, in most states, have assumed as part of their franchise agreement. Regulators, courts, utilities, marketers and others are busy sorting through these issues, but resolution could take years. The paper discusses deregulation, universal service fee, representation without taxation, suppliers and marketer restrictions

    Full Text Available Numerous studies have demonstrated a relationship between Mediterranean Diet (MD adherence and the prevention of cardiovascular diseases, cancer, and diabetes, etc. The study aim was to validate a novel instrument to measure MD adherence based on the consumption of food servings and food groups, and apply it in a female population from southern Spain and determining influential factors.The study included 1,155 women aged 12-83 yrs, classified as adolescents, adults, and over-60-yr-olds. All completed a validated semi-quantitative food frequency questionnaire (FFQ. The Mediterranean Dietary Serving Score (MDSS is based on the latest update of the Mediterranean Diet Pyramid, using the recommended consumption frequency of foods and food groups; the MDSS ranges from 0 to 24. The discriminative power or correct subject classification capacity of the MDSS was analyzed with the Receiver Operating Characteristic (ROC curve, using the MDS as reference method. Predictive factors for higher MDSS adherence were determined with a logistic regression model, adjusting for age. According to ROC curve analysis, MDSS evidenced a significant discriminative capacity between adherents and non-adherents to the MD pattern (optimal cutoff point=13.50; sensitivity=74%; specificity=48%. The mean MDSS was 12.45 (2.69 and was significantly higher with older age (p<0.001. Logistic regression analysis showed highest MD adherence by over 60-year-olds with low BMI and no habit of eating between meals.The MDSS is an updated, easy, valid, and accurate instrument to assess MD adherence based on the consumption of foods and food groups per meal, day, and week. It may be useful in future nutritional education programs to prevent the early onset of chronic non-transmittable diseases in younger populations.

    Eddy, Sarah L; Converse, Mercedes; Wenderoth, Mary Pat

    2015-01-01

    There is extensive evidence that active learning works better than a completely passive lecture. Despite this evidence, adoption of these evidence-based teaching practices remains low. In this paper, we offer one tool to help faculty members implement active learning. This tool identifies 21 readily implemented elements that have been shown to increase student outcomes related to achievement, logic development, or other relevant learning goals with college-age students. Thus, this tool both clarifies the research-supported elements of best practices for instructor implementation of active learning in the classroom setting and measures instructors' alignment with these practices. We describe how we reviewed the discipline-based education research literature to identify best practices in active learning for adult learners in the classroom and used these results to develop an observation tool (Practical Observation Rubric To Assess Active Learning, or PORTAAL) that documents the extent to which instructors incorporate these practices into their classrooms. We then use PORTAAL to explore the classroom practices of 25 introductory biology instructors who employ some form of active learning. Overall, PORTAAL documents how well aligned classrooms are with research-supported best practices for active learning and provides specific feedback and guidance to instructors to allow them to identify what they do well and what could be improved. © 2015 S.

    2013-06-01

    "Mars: On the shoulder of giants" is a freshmen year seminar developed collaboratively between the physics, education, and center for teaching and learning. This course focuses on how scientific knowledge is developed through the lens of our changing view of Mars throughout history. Analyses of current studies of Mars are juxtaposed against historical understanding and perceptions of the planet found in scientific and popular literature of the day, as well as the movies. Kim Stanley Robinson’s "Red Mars" provides a unifying story throughout the course complimented by Fredrick Taylor’s "The Scientific Exploration of Mars" and Hartmann’s "A Traveler’s Guide to Mars." Based on the three-years of experience, the authors advocate the use of the speculative science-fiction novel and argue for its use in high school and undergraduate courses including those for science majors. Many of the students who selected this seminar went on to major in science and in subsequent interviews discussed the influence of science fiction on their decision to major in science. Science fiction provided story, science, and speculation that became a rich medium for critical-thinking skills and critical literacy. Student reflections indicated that science fiction served as a reminder of why they study science, a source for imagination, and exploration of science as a human endeavor. Based on this experience, we propose five elements for selecting science-fiction for inclusion in science classes: 1) Provides a deep description of the science content or technologies, 2) Describes science and technologies are plausible or accurate to the time period, 3) Contains a novum or plausible innovation that plays a key element in the speculation, 4) Exploration of the impact on society or humanity, and, 5) Shows science and technology as human endeavors.

    commissioned a comprehensive survey to determine user satisfaction using the American Customer Satisfaction Index (ACSI) approach. The results show that, overall, the users are highly satisfied with the EOSDIS systems and services as the EOSDIS ACSI score outperformed both the averages for U.S. companies and for Federal Agencies. Noteworthy was the fact that there was no statistical difference in the quality scores received by the various EOSDIS data centers. The response indicated that customer support provided by the EOSDIS Distributed Active Archive Centers (DAACs) is "world class" and that a very high number of users intend to use EOSDIS in the future (90%) and to recommend it to their colleagues (86%). The survey highlighted areas that, if improved, could lead to increased user satisfaction, including overall product quality, product documentation, and product selection and ordering processes. These results will be factored into NASA's evolution planning.

    To protect and promote the well-being of others, humans may bend the truth and behave unethically. Here we link such tendencies to oxytocin, a neuropeptide known to promote affiliation and cooperation with others. Using a simple coin-toss prediction task in which participants could dishonestly report their performance levels to benefit their group's outcome, we tested the prediction that oxytocin increases group-serving dishonesty. A double-blind, placebo-controlled experiment allowing individuals to lie privately and anonymously to benefit themselves and fellow group members showed that healthy males (n = 60) receiving intranasal oxytocin, rather than placebo, lied more to benefit their group, and did so faster, yet did not necessarily do so because they expected reciprocal dishonesty from fellow group members. Treatment effects emerged when lying had financial consequences and money could be gained; when losses were at stake, individuals in placebo and oxytocin conditions lied to similar degrees. In a control condition (n = 60) in which dishonesty only benefited participants themselves, but not fellow group members, oxytocin did not influence lying. Together, these findings fit a functional perspective on morality revealing dishonesty to be plastic and rooted in evolved neurobiological circuitries, and align with work showing that oxytocin shifts the decision-maker's focus from self to group interests. These findings highlight the role of bonding and cooperation in shaping dishonesty, providing insight into when and why collaboration turns into corruption.

    Studies were carried out at the Food Technology Research Department of Myanma Scientific and Technological Research Department to prepare ready to serve grape juice from ripe fruits of the red varieties of grapes. The sugar content of grapes varied from (10) to (14) % depending on the season. To get a maximum content of (16) % sugar in the juice, (2) to (6) % sugar was added. The yields of the seasonal grape juice varied from (62.5) to (72.2) % by weight. The tannin content was (0.36) % by volume in the fresh juice. It was decreased to (0.03) % by volume after the cold storage at (10)C for (10 to 15) days. The pH of the original fruit juice was (3.2). The best juice was obtain when the pH of the juice was(4.0). To obtain the higher yield of the juice, desirable bright colour and rapid clarification, (0.01) %. Pectinex enzyme was added. In this investigation grape juice was preserved with (0.1) % sodium benzoate. Storage studies, which also included microbiological aspects indicated that the pasteurized grape juice bottle can be stored at room temperature for minimum (6) months without any deterioration in quality

    LEIR is the CERN facility that produces high-density ion beams for the LHC and for the SPS fixed target experiments. Since its operational schedule is not fully booked, LEIR could, in principle, be exploited even further. A brainstorming meeting recently took place at CERN to evaluate the possibility of modifying LEIR to serve the biomedical community. Discussions are in progress.   The Low Energy Ion Ring (LEIR). LEIR is a small synchrotron with a circumference of about 78 m. It currently receives particles from Linac 3 and prepares beams for the SPS and the LHC. “In order for LEIR to be able to provide ion beams with appropriate energies for studies of interest for biomedical applications, a new ejection system with new beam lines needs to be designed,” explains Christian Carli, from the Beams Department. “In addition, Linac 3 could be upgraded to include a second ion source and a radio frequency quadrupole (RFQ) optimized for ions of interest for bi...

  3. Russia's social upper class: from ostentation to culturedness.

    Schimpfossl, Elisabeth

    2014-03-01

    This article discusses examples of strategies employed by representatives of Russia's new social upper class to acquire social distinction. By the late 2000s many of the upper-class Russians included in this study distanced themselves from the conspicuous ostentation ascribed to the brutish 1990s. Instead, they strove to gain legitimacy for their social position by no longer aggressively displaying their wealth, but instead elaborating more refined and individualized tastes and manners and reviving a more cultured image and self-image. These changes found their expression in various modes of social distinction ranging from external signs, such as fashion and cars, to ostentation vicariously exercised through the people these upper-class Russians surrounded themselves with. The article will trace these interviewees' strategies for distinction in the late 2000s by discussing tastes in lifestyle and consumption as well as adornment through sartorial signs and through vicarious ostentation, as exemplified by their choice of female company. Changing attitudes towards vehicles and modes of transport, with special regards to the Moscow Metro, will serve as a further illustration of modes of distinction. Crucial for this discussion is the role of the Russian/Soviet intelligentsia, both for vicarious status assertion and elite distinction anchored in the interviewees' social backgrounds. © London School of Economics and Political Science 2014.

  4. Serving some and serving all: how providers navigate the challenges of providing racially targeted health services.

    Science.gov (United States)

    2017-10-01

    Racially targeted healthcare provides racial minorities with culturally and linguistically appropriate health services. This mandate, however, can conflict with the professional obligation of healthcare providers to serve patients based on their health needs. The dilemma between serving a particular population and serving all is heightened when the patients seeking care are racially diverse. This study examines how providers in a multi-racial context decide whom to include or exclude from health programs. This study draws on 12 months of ethnographic fieldwork at an Asian-specific HIV organization. Fieldwork included participant observation of HIV support groups, community outreach programs, and substance abuse recovery groups, as well as interviews with providers and clients. Providers managed the dilemma in different ways. While some programs in the organization focused on an Asian clientele, others de-emphasized race and served a predominantly Latino and African American clientele. Organizational structures shaped whether services were delivered according to racial categories. When funders examined client documents, providers prioritized finding Asian clients so that their documents reflected program goals to serve the Asian population. In contrast, when funders used qualitative methods, providers could construct an image of a program that targets Asians during evaluations while they included other racial minorities in their everyday practice. Program services were organized more broadly by health needs. Even within racially targeted programs, the meaning of race fluctuates and is contested. Patients' health needs cross cut racial boundaries, and in some circumstances, the boundaries of inclusion can expand beyond specific racial categories to include racial minorities and underserved populations more generally.

    2003-05-01

    As science educators struggle to reform science education, we need a better understanding of the conundrums associated with the ways educators enact innovative science within and against the academic, rigorous, and elite sociohistorical constructions of science. I ethnographically investigated the meanings of an innovative, reform-based curriculum (Active Physics) in various micro (classroom) and macro (school and community) contexts. I conducted the study in a high school serving primarily upper middle class students, the majority of whom (97%) planned to attend college. I explored how meanings of the curriculum transformed as the curriculum traveled across space and time. While certain aspects of the context enabled innovative science (e.g., support from the administration, pressure to serve a wider range of students), other aspects of the context constrained the potential of the curriculum (e.g., the need to establish for students, parents, and administrators the legitimacy of Active Physics as real and rigorous physics). Using practice theory to understand the influence of context and agency in shaping school science practice, this study demonstrates the potential for viewing meanings of science in local settings as partially fluid entities, sometimes reproducing and sometimes contesting sociohistorical legacies.

    Several geospatial web servers, web service standards, and mapping clients exist for the visualization of two-dimensional raster and vector-based Earth science data products. However, data products with a vertical component (i.e., vertical profiles) do not have the same mature set of technologies and pose a greater technical challenge when it comes to visualizations. There are a variety of tools and proposed standards, but no obvious solution that can handle the variety of visualizations found with vertical profiles. An effort is being led by members of the NASA Global Imagery Browse Services (GIBS) team to gather a list of technologies relevant to existing vertical profile data products and user stories. The goal is to find a subset of technologies, standards, and tools that can be used to build publicly accessible web services that can handle the greatest number of use cases for the widest audience possible. This presentation will describe results of the investigation and offer directions for moving forward with building a system that is capable of effectively and efficiently serving visualizations of vertical profiles.

    Watson, Wendy L; Kury, Alexandra; Wellard, Lyndal; Hughes, Clare; Dunford, Elizabeth; Chapman, Kathy

    2016-01-01

    This study examined the serving size and energy content per serving of Australian packaged snack foods and confectionery products. Nutrition Information Panel data for 23 sub-categories of packaged snack foods (n = 3481) were extracted from The George Institute for Global Health's 2013 branded food composition database. Variations in serving size and energy content per serving were examined. Energy contents per serving were compared to recommendations in the Australian Dietary Guidelines. Serving sizes varied within and between snack food categories. Mean energy content per serving varied from 320 kJ to 899 kJ. More energy per serving than the recommended 600 kJ was displayed by 22% (n = 539) of snack foods classified in the Australian Dietary Guidelines as discretionary foods. The recommendation for energy content per serving was exceeded in 60% (n = 635) of snack foods from the Five Food Groups. Only 37% (n = 377) of confectionery products displayed the industry-agreed serving size of 25 g. Energy content per serving of many packaged snack foods do not align with the Australian Dietary Guidelines and the industry agreed serving size has not been taken up widely within the confectionery category. Given the inconsistencies in serving sizes, featuring serving size in front-of-pack information may hinder the objective of a clear and simple nutrition message. Messaging to help consumers make healthier choices should consider the variation in serving sizes on packaged snack foods. Copyright © 2015 Elsevier Ltd. All rights reserved.

  17. Self-Serving Bias or Simply Serving the Self? Evidence for a Dimensional Approach to Narcissism.

    Science.gov (United States)

    Tamborski, Michael; Brown, Ryan P; Chowning, Karolyn

    2012-06-01

    Previous research has suggested that narcissism can be conceptualized as a multidimensional construct consisting of the related, but unique, dimensions of grandiosity and entitlement. The current studies examined the divergent associations of grandiosity and entitlement with respect to different types of self-serving strategies. In Study 1, we found that narcissistic grandiosity, but not entitlement, was positively associated with a self-enhancing strategy of unrealistic optimism. This association was not mediated by self-esteem. In Study 2, narcissistic entitlement, but not grandiosity, was predictive of unethical decision-making, an interpersonal self-promotional strategy that advances the self at the expense of others. Together, both studies support a model of narcissism consisting of a relatively intrapersonal dimension of grandiosity and a relatively interpersonal dimension of entitlement.

    Southerland, Sherry; Gallard, Alejandro; Callihan, Laurie

    2011-11-01

    The goal of this research is to identify science teachers' beliefs and conceptions that play an important role in shaping their understandings of and attempts to enact inclusive science teaching practices. We examined the work products, both informal (online discussions, email exchanges) and formal (papers, unit plans, peer reviews), of 14 teachers enrolled in a master's degree course focused on diversity in science teaching and learning. These emerging understandings were member-checked via a series of interviews with a subset of these teachers. Our analysis was conducted in two stages: (1) describing the difficulties the teachers identified for themselves in their attempts to teach science to a wide range of students in their classes and (2) analyzing these self-identified barriers for underlying beliefs and conceptions that serve to prohibit or allow for the teachers' understanding and enactment of equitable science instruction. The teachers' self-identified barriers were grouped into three categories: students, broader social infrastructure, and self. The more fundamental barriers identified included teacher beliefs about the ethnocentrism of the mainstream, essentialism/individualism, and beliefs about the meritocracy of schooling. The implications of these hurdles for science teacher education are discussed.

  4. Relationship of sex, achievement, and science self-concept to the science career preferences of black students

    Science.gov (United States)

    Jacobowitz, Tina

    Science career preferences of junior high school-aged students, while not stable predictors of ultimate career choice, do serve to direct and maintain individuals along the paths to careers in science. In this study, factors relevant to science career preferences of black eighth grade students were investigated. This issue is of particular import to blacks since they are severely underrepresented in the scientific fields. The sample consisted of 113 males and 148 females in an inner city junior high school. The Science Career Preference Scale, the Peabody Picture Vocabulary Test, and the Self-Concept of Ability Scale (Form B-Science) were administered. Mathematics and science grades were obtained from class rating sheets. Treatment of the data involved multiple regression analysis according to a hierarchical model. Results showed that of all the independent variables, sex was the strongest predictor of science career preferences, accounting for 25% of the criterion variance. The findings suggest that early adolescent science career preferences are related more to interests that are consonant with sex-role considerations than realistic assessment of mathematics or science achievement.

    Kraus, Michael W; Park, Jun Won

    2017-12-01

    Individual agency accounts of social class persist in society and even in psychological science despite clear evidence for the role of social structures. This article argues that social class is defined by the structural dynamics of society. Specifically, access to powerful networks, groups, and institutions, and inequalities in wealth and other economic resources shape proximal social environments that influence how individuals express their internal states and motivations. An account of social class that highlights the means by which structures shape and are shaped by individuals guides our understanding of how people move up or down in the social class hierarchy, and provides a framework for interpreting neuroscience studies, experimental paradigms, and approaches that attempt to intervene on social class disparities.

  8. Training in Geoethics: Shared Values in Serving Society

    Science.gov (United States)

    Peppoloni, S.; Di Capua, G.

    2014-12-01

    Geosciences have evident repercussions on society. Geoscientists possess knowledge and skills to investigate, manage and intervene on the Geosphere, and this implies ethical obligations. So, the adoption of ethical principles and standards is crucial if geoscientists want to best serve the public. Their ethical responsibility requires a more active role in interacting with society, by giving people valuable contexts that inform the need for sustainable development, and perspectives that reveal essential and delicate balances of natural systems that impact humanity. Geoethics consists of research and reflection on those values upon which to base appropriate behaviour and practices where human activities intersect the Geosphere, and should become an essential point of reference in geoscientists' curricula. Acting in this direction implies the awareness by the geological community of its ethical commitments and the necessity to train new generations of geoscientists that in the future will be able to transfer to society not only practical aspects of geological knowledge, but also a new way to understand our planet. The IAPG - International Association for Promoting Geoethics (www.iapg.geoethics.org) was born to build a new awareness in the scientific community. It aims at joining forces of geoscientists all over the world, through creation of an international, multidisciplinary and scientific platform for discussing ethical problems and dilemmas in Earth Sciences, for strengthening the research base on Geoethics through scientific publications and conferences. Its main goal is to give a new cultural framework of reference, in which to develop effective training tools, in order to sensitize young geoscientists on ethical and social issues related to their future work, starting from the definition of shared values within the scientific community. This work provides an overview on the IAPG goals, activities and ongoing initiatives.

  10. The ongoing educational anomaly of earth science placement

    Messina, P.; Speranza, P.; Metzger, E.P.; Stoffer, P.

    2003-01-01

    The geosciences have traditionally been viewed with less "aCademic prTstige" than other science curricula. Among the results of this perception are depressed K-16 enrollments, Earth Science assignments to lower-performing students, and relegation of these classes to sometimes under-qualified educators, all of which serve to confirm the widely-held misconceptions. An Earth Systems course developed at San Jos??e State University demonstrates the difficulty of a standard high school Earth science curriculum, while recognizing the deficiencies in pre-college Earth science education. Restructuring pre-college science curricula so that Earth Science is placed as a capstone course would greatly improve student understanding of the geosciences, while development of Earth systems courses that infuse real-world and hands-on learning at the college level is critical to bridging the information gap for those with no prior exposure to the Earth sciences. Well-crafted workshops for pre-service and inservice teachers of Earth Science can heIp to reverse the trends and unfortunate "sTatus" in geoscience education.

  11. Using children's literature to enhance views of nature of science and scientific attitude in fourth graders

    Hampton, Kathryn Walker

    This project was an effort to study the effect of integrating children's trade books into the fourth grade science curriculum on the students' views of the nature of science and their scientific attitude. The effect on the students' reading and language achievement, and science content knowledge was also analyzed. This was done by comparing the nature of science views and scientific attitudes, reading and language achievement scores, and the science grades of the treatment group, prior to and immediately following the intervention period, with the control group which did not participate in the integration of children's books. The science teacher's views on the nature of science and her attitude towards teaching science were also evaluated prior to and after the intervention. The selected trade books were evaluated for their coverage of nature of science aspects. Three intact classes of fourth grade students from a local elementary school were involved in the study along with their science and reading teacher. Two of the classes made up the experimental group and the remaining class served as the control group. All students were assessed prior to the intervention phase on their views of the nature of science and scientific attitudes. The experimental group was engaged in reading selected science trade books during their science class and study hall over a semester period. The results of the study showed a significant difference in the groups' initial reading and language achievement, which may have affected the lack of an effect from the intervention. The instrument selected to assess the student's views on the nature of science and scientific attitude (SAI II) was not reliable with this group. There was no significant difference on the students' science content knowledge as measured by their semester grade averages. The results from the teacher's response on the STAS II did indicate slight changes on her views on the nature of science. Sixty-nine of the eighty

    2017-08-01

    The PAD Class (Presentation-Assimilation-Discussion) is a new paradigm for classroom teaching combining strengths of lecture and discussion. With half class time allocated for teacher's presentation and the other half for students' discussion, an assimilation stage was inserted between presentation and discussion for independent and individualized learning. Since its first success in 2014, the PAD method has gained national popularity in China and been successfully put into practice by thousands of college teachers in nearly all subjects, e.g., science, engineering, medical sciences, social sciences, humanities and arts. This paper analyzed the psychological and pedagogical rationales underlying the PAD Class to explicate its effectiveness in enhancing active learning.

    Enhancing the understanding of coordination and variability in the tennis serve may be of interest to coaches as they work with players to improve performance. The current study examined coordinated joint rotations and variability in the lower limbs, trunk, serving arm and ball location in the elite female tennis serve. Pre-pubescent, pubescent and adult players performed maximal effort flat serves while a 22-camera 500 Hz motion analysis system captured three-dimensional body kinematics. Coordinated joint rotations in the lower limbs and trunk appeared most consistent at the time players left the ground, suggesting that they coordinate the proximal elements of the kinematic chain to ensure that they leave the ground at a consistent time, in a consistent posture. Variability in the two degrees of freedom at the elbow became significantly greater closer to impact in adults, possibly illustrating the mechanical adjustments (compensation) these players employed to manage the changing impact location from serve to serve. Despite the variable ball toss, the temporal composition of the serve was highly consistent and supports previous assertions that players use the location of the ball to regulate their movement. Future work should consider these associations in other populations, while coaches may use the current findings to improve female serve performance.

    2013-12-01

    Studies of the relationship between class position and political outlooks still only have a limited understanding of the class-related mechanisms that matter for ideological orientations. This article presents a comprehensive analysis of the mechanisms that link class position and left/right and authoritarian/libertarian orientations. Besides main factors such as income, career prospects, job security, education, class origin and class identification, the significance of work-related factors such as work autonomy, working in a team, a physically demanding job and a mentally demanding job is studied. The findings are based on a survey specifically designed for this purpose and collected in Sweden in 2008/2009. A great deal of the association between class position and left/right orientations is explained by socio-economic conditions; different classes sympathize with policies that will benefit them economically. Another important factor is class identification. Work-related factors also have relevance, but the effect of class position on left/right orientations works mainly through the remuneration system. Class position is also related to authoritarian/libertarian orientations. However, this relationship is less explained by socio-economic position per se, but is rather an effect of the educational system and its allocation of the workforce into different class positions. It also turns out that work-related factors do not explain the class effects; however, a physically demanding job shows a unique effect. Overall, our findings suggest that besides factors such as class position, income, education and class identification, we need to consider work-related aspects to derive a more complete understanding of the distribution of ideological orientations in Western societies. © London School of Economics and Political Science 2013.

    A large body of research in Western cultures has demonstrated the psychological and health effects of social class. This review outlines a cultural psychological approach to social stratification by comparing psychological and health manifestations of social class across Western and East Asian cultures. These comparisons suggest that cultural meaning systems shape how people make meaning and respond to material/structural conditions associated with social class, thereby leading to culturally divergent manifestations of social class. Specifically, unlike their counterparts in Western cultures, individuals of high social class in East Asian cultures tend to show high conformity and other-orientated psychological attributes. In addition, cultures differ in how social class impacts health (i.e. on which bases, through which pathways, and to what extent). Copyright © 2017 Elsevier Ltd. All rights reserved.

    technology revolution. Interfaces gave them their functions, and shaping them into ever-smaller functional components made them indispensably omnipresent as transistors—produced in billions per person and per year—and they are no doubt the rulers of today's technical world.The semiconductor and transistor serve as an inspiring example of functionalizing materials. The developments of microelectronics profited very much from scalability, that is, the properties and functions do not change significantly with size. Therefore, every step toward smaller dimensions was a technical and commercial challenge with risks well under control. The transition to the nanoscale, however, is discontinuous. Examples of this transition are the local probe methods that exploit the mechanically controlled proximity to the object under consideration and that have become indispensable as microscopes and as measuring and modifying tools, the size of molecular components that are much smaller than the smallest possibly achievable transistor, the properties and functions of materials below a critical size as mentioned above, the continuum properties versus discrete ones, and novel concepts inspired by living nature. Those novel concepts include growing circuits first and building the active components at the nodes afterwards and measuring weak by weak, small by small, and many by many. It is these discontinuous steps that make the nanoscale different, not just smaller. They pose exciting challenges, open great opportunities and nearly unlimited possibilities, but they also carry serious technical, commercial, environmental, and health risks.The nanoscale is also a great opportunity for materials science in general. Materials science is interdisciplinary per se. A materials scientist should have a reasonable understanding of physics, chemistry, engineering, and more recently, also biology. Certainly one can always team up with representatives from other disciplines and forge collaborations. However

  15. Classes of modules

    2006-01-01

    Because traditional ring theory places restrictive hypotheses on all submodules of a module, its results apply only to small classes of already well understood examples. Often, modules with infinite Goldie dimension have finite-type dimension, making them amenable to use with type dimension, but not Goldie dimension. By working with natural classes and type submodules (TS), Classes of Modules develops the foundations and tools for the next generation of ring and module theory. It shows how to achieve positive results by placing restrictive hypotheses on a small subset of the complement submodules, Furthermore, it explains the existence of various direct sum decompositions merely as special cases of type direct sum decompositions. Carefully developing the foundations of the subject, the authors begin by providing background on the terminology and introducing the different module classes. The modules classes consist of torsion, torsion-free, s[M], natural, and prenatural. They expand the discussion by exploring...

    2018-01-01

    The Cosmology Large Angular Scale Surveyor (CLASS) is an array of four telescopes designed to measure the polarization of the Cosmic Microwave Background. CLASS aims to detect the B-mode polarization from primordial gravitational waves predicted by cosmic inflation theory, as well as the imprint left by reionization upon the CMB E-mode polarization. This will be achieved through a combination of observing strategy and state-of-the-art instrumentation. CLASS is observing 70% of the sky to characterize the CMB at large angular scales, which will measure the entire CMB power spectrum from the reionization peak to the recombination peak. The four telescopes operate at frequencies of 38, 93, 145, and 217 GHz, in order to estimate Galactic synchrotron and dust foregrounds while avoiding atmospheric absorption. CLASS employs rapid polarization modulation to overcome atmospheric and instrumental noise. Polarization sensitive cryogenic detectors with low noise levels provide CLASS the sensitivity required to constrain the tensor-to-scalar ratio down to levels of r ~ 0.01 while also measuring the optical depth the reionization to sample-variance levels. These improved constraints on the optical depth to reionization are required to pin down the mass of neutrinos from complementary cosmological data. CLASS has completed a year of observations at 38 GHz and is in the process of deploying the rest of the telescope array. This poster provides an overview and update on the CLASS science, hardware and survey operations.

    joint-activities” types of meetings is also considerably more common among those with a non-Norwegian cultural/linguistic background. Frequency of library use in general was not related to participation in either of these two types of meetings at the library, but it was related to library use for the more low-intensive meeting types (chance meetings and encounters, library as rendezvous point for joint activities elsewhere, as well as to what the investigators term using the library as a “metameeting place,” i.e., a place for finding “information about other arenas and activities” in the local community.Conclusion – The local public library seems to serve, for many of its patrons, an important function as venue for meetings of various kinds. In general, using it for meeting purposes appears to be something that appeals more to younger than to older adults, more to those in the lower than to those in the higher income categories, and more to those with an immigrant than to those with an indigenous background. The perhaps even less expected finding that use of the library for a relatively intensive, instrumental kind of meeting activity correlates significantly with a lower level of education would particularly suggest a need for further research. Noteworthy, as well, is the apparent fact that those who make use of the local public library as a venue for relatively intensive meeting activity, whether physical or virtual, tend to come to the library expressly for that purpose, and visit the library less often for other reasons than do other library users. The urban districts in which respondents resided were in fact not internally homogeneous enough, nor socio-economically distinct enough from one another, to yield correlations of practical evidentiary value.It was the researchers’ working assumption that their three independent variables of community engagement – i.e., level of participation in local activities, degree of involvement in community improvement activities, and

    The School of Ice (SOI) program from the US Ice Drilling Program Office (IDPO) is designed for college faculty who teach at minority-serving institutions or historically black colleges and universities, but lessons learned transfer easily to any science course based on current research. The institute builds participants' background knowledge about ice core science and climate change while also providing experiences with activities and labs for transferring information to their students. After three years of highly successful workshops, our model has provided valuable lessons for creating powerful experiences for participants. This presentation will identify some of the key ideas including pairing researchers and educators as presenters; creating leadership teams capitalizing on partner strengths; building a science community willing to participate in education and outreach; and building participants' science content background knowledge and confidence while providing them with teaching models for transferring the knowledge to their students. Another important element is to demand teacher buy-in to ensure replication and dissemination. Also, IDPO's drilling technologies make it an ideal platform for intertwining engineering concepts and practices with science research to meet new science standards. In this session, we will share results of the institute evaluations including the impact on the educators as well as longitudinal analysis of data from interviews with past participants concerning continued impacts on their teaching, their courses and their students. Faculty who have attended this institute in the last three years have reported increases in their understanding of the content and how to teach it. They also report increased confidence in their ability to teach ice core science and climate change concepts. Elements of these successful workshops can inform both the development of college professional development and student courses, as well as the creation of

  8. Mapping classroom experiences through the eyes of enlace students: The development of science literate identities

    Science.gov (United States)

    Oemig, Paulo Andreas

    The culture of a science classroom favors a particular speech community, thus membership requires students becoming bilingual and bicultural at the same time. The complexity of learning science rests in that it not only possesses a unique lexicon and discourse, but it ultimately entails a way of knowing. My dissertation examined the academic engagement and perceptions of a group (N=30) of high school students regarding their science literate practices. These students were participating in an Engaging Latino Communities for Education (ENLACE) program whose purpose is to increase Latino high school graduation rates and assist them with college entrance requirements. At the time of the study, 19 students were enrolled in different science classes to fulfill the science requirements for graduation. The primary research question: What kind of science classroom learning environment supports science literate identities for Latino/a students? was addressed through a convergent parallel mixed research design (Creswell & Plano Clark, 2011). Over the course of an academic semester I interviewed all 30 students arranged in focus groups and observed in their science classes. ENLACE students expressed interest in science when it was taught through hands-on activities or experiments. Students also stressed the importance of having teachers who made an effort to get to know them as persons and not just as students. Students felt more engaged in science when they perceived their teachers respected them for their experiences and knowledge. Findings strongly suggest students will be more interested in science when they have opportunities to learn through contextualized practices. Science literate identities can be promoted when inquiry serves as a vehicle for students to engage in the language of the discipline in all its modalities. Inquiry-based activities, when carefully planned and implemented, can provide meaningful spaces for students to construct knowledge, evaluate claims

    Full Text Available This study aims to investigate the construct validity and reliability of the checklist for qualitative analysis of the overhand serve in Volleyball. Fifty-five male subjects aged 13-17 years participated in the study. The overhand serve was analyzed using the checklist proposed by Meira Junior (2003, which analyzes the pattern of serve movement in four phases: (I initial position, (II ball lifting, (III ball attacking, and (IV finalization. Construct validity was analyzed using confirmatory factorial analysis and reliability through the Cronbach’s alpha coefficient. The construct validity was supported by confirmatory factor analysis with the RMSEA results (0.037 [confidence interval 90% = 0.020-0.040], CFI (0.970 and TLI (0.950 indicating good fit of the model. In relation to reliability, Cronbach’s alpha coefficient was 0.661, being this value considered acceptable. Among the items on the checklist, ball lifting and attacking showed higher factor loadings, 0.69 and 0.99, respectively. In summary, the checklist for the qualitative analysis of the overhand serve of Meira Junior (2003 can be considered a valid and reliable instrument for use in research in the field of Sports Sciences.

    Central to the recruitment of students into science teaching at a school like CSU, is a focus on the professional nature of teaching. The purpose of this focus is twofold: it serves to change student perceptions about teaching and it prepares students to become teachers who value continued professional development and value the science education research literature. The Noyce and PhysTEC programs at CSU place the professional nature of teaching front and center by involving students in education research projects, paid internships, attendance at conferences, and participation in a new Teacher Immersion Institute and a Science Education Journal Reading Class. This poster will focus on specific components of our teacher preparation program that were developed through these two programs. In addition we will describe how these new components provide students with diverse experiences in the teaching of science to students in the urban school district. Supported by the NSF Noyce Program (0833251) and the APS PhysTEC Program.

    The Large Synoptic Survey Telescope Corporation (LSSTC) Data Science Fellowship Program (DSFP) is a unique professional development program for astronomy graduate students. DSFP students complete a series of six, one-week long training sessions over the course of two years. The sessions are cumulative, each building on the last, to allow an in-depth exploration of the topics covered: data science basics, statistics, image processing, machine learning, scalable software, data visualization, time-series analysis, and science communication. The first session was held in Aug 2016 at Northwestern University, with all materials and lectures publicly available via github and YouTube. Each session focuses on a series of technical problems which are written in iPython notebooks. The initial class of fellows includes 16 students selected from across the globe, while an additional 14 fellows will be added to the program in year 2. Future sessions of the DSFP will be hosted by a rotating cast of LSSTC member institutions. The DSFP is designed to supplement graduate education in astronomy by teaching the essential skills necessary for dealing with big data, serving as a resource for all in the LSST era. The LSSTC DSFP is made possible by the generous support of the LSST Corporation, the Data Science Initiative (DSI) at Northwestern, and CIERA.

    2018-01-01

    Full Text Available Most of object-oriented development technologies rely on the use of the universal modeling language UML; class diagrams play a very important role in the design process play, used to build a software system model. Modern CASE tools, which are the basic tools for object-oriented development, can’t be used to optimize UML diagrams. In this manuscript we will explain how, based on the use of design patterns and anti-patterns, class diagrams could be verified and optimized. Certain transformations can be carried out automatically; in other cases, potential inefficiencies will be indicated and recommendations given. This study also discusses additional CASE tools for validating and optimizing of UML class diagrams. For this purpose, a plugin has been developed that analyzes an XMI file containing a description of class diagrams.

    The objective was to identify the prevalence of and variables associated with unintended pregnancy among young, unmarried women serving in the Israeli military. We performed a retrospective cohort study of unmarried women drafted by the Israeli military between 2013 and 2015 at the age of 18 years. We used multivariable logistic regression to examine associations between unintended pregnancy and women's education, IQ, immigration status, country of origin, neighborhood socioeconomic status and history of psychiatric illness. Most women (n=127,262) did not become pregnant while serving in the Israeli military. Unintended pregnancy was reported by 2365, with an additional 6 women reporting pregnancy resulting from sexual assault and 5 an intended pregnancy. Annual rates of unintended pregnancy among young women serving in the Israeli military declined from 1.69% in 2013 to 1.56% in 2014 and 1.33% in 2015. In multivariable models, unintended pregnancy was more common among women soldiers who had not graduated from high school (adjusted relative risk [RR], 5.3; 95% confidence interval [CI], 4.69-6.04) and those who were first-generation immigrants (adjusted RR, 2.1; 95% CI, 1.90-2.35). Unintended pregnancy is rare among women serving into the Israeli military. Increasing contraceptive use among women who have not graduated from high school may further reduce rates of unintended pregnancy among women serving in the Israeli military.

  18. Influence of a Prolonged Tennis Match Play on Serve Biomechanics.

    Directory of Open Access Journals (Sweden)

    Caroline Martin

    Full Text Available The aim of this study was to quantify kinematic, kinetic and performance changes that occur in the serve throughout a prolonged tennis match play. Serves of eight male advanced tennis players were recorded with a motion capture system before, at mid-match, and after a 3-hour tennis match. Before and after each match, electromyographic data of 8 upper limb muscles obtained during isometric maximal voluntary contraction were compared to determine the presence of muscular fatigue. Vertical ground reaction forces, rating of perceived exertion, ball speed, and ball impact height were measured. Kinematic and upper limb kinetic variables were computed. The results show decrease in mean power frequency values for several upper limb muscles that is an indicator of local muscular fatigue. Decreases in serve ball speed, ball impact height, maximal angular velocities and an increase in rating of perceived exertion were also observed between the beginning and the end of the match. With fatigue, the majority of the upper limb joint kinetics decreases at the end of the match. No change in timing of maximal angular velocities was observed between the beginning and the end of the match. A prolonged tennis match play may induce fatigue in upper limb muscles, which decrease performance and cause changes in serve maximal angular velocities and joint kinetics. The consistency in timing of maximal angular velocities suggests that advanced tennis players are able to maintain the temporal pattern of their serve technique, in spite of the muscular fatigue development.

    Context. Infrared-faint radio sources (IFRS) represent an unexpected class of objects which are relatively bright at radio wavelength, but unusually faint at infrared (IR) and optical wavelengths. A recent and extensive campaign on the radio-brightest IFRSs (S1.4 GHz≳ 10 mJy) has provided evidence that most of them (if not all) contain an active galactic nuclei (AGN). Still uncertain is the nature of the radio-faintest IFRSs (S1.4 GHz≲ 1 mJy). Aims: The scope of this paper is to assess the nature of the radio-faintest IFRSs, testing their classification and improving the knowledge of their IR properties by making use of the most sensitive IR survey available so far: the Spitzer Extragalactic Representative Volume Survey (SERVS). We also explore how the criteria of IFRSs can be fine-tuned to pinpoint radio-loud AGNs at very high redshift (z > 4). Methods: We analysed a number of IFRS samples identified in SERVS fields, including a new sample (21 sources) extracted from the Lockman Hole. 3.6 and 4.5 μm IR counterparts of the 64 sources located in the SERVS fields were searched for and, when detected, their IR properties were studied. Results: We compared the radio/IR properties of the IR-detected IFRSs with those expected for a number of known classes of objects. We found that IR-detected IFRSs are mostly consistent with a mixture of high-redshift (z ≳ 3) radio-loud AGNs. The faintest ones (S1.4 GHz 100 μJy), however, could be also associated with nearer (z 2) dust-enshrouded star-burst galaxies. We also argue that, while IFRSs with radio-to-IR ratios >500 can very efficiently pinpoint radio-loud AGNs at redshift 2 < z < 4, lower radio-to-IR ratios ( 100-200) are expected for higher redshift radio-loud AGNs.

  3. The Accounting Profession: Serving the Public Interest or Capital Interest?

    2008-12-01

    Full Text Available As an integral facet of society, the accounting profession has a role in the State and thecorporate sector, and is also expected to serve the public interest. The capacity for theAustralian accounting profession to serve the public interest is considered in the context oflegislation and the accounting standard setting process. Specific reference is made to theCLERP Act 1999 and ASIC Act 2001. It is argued that the combined effect of these Acts is tolegislate bias so that accounting standards privilege the specific needs of holders of capital,that is capital interest. The assumption that capital markets are surrogate for the publicinterest is contested. Accordingly, if the accounting profession follows national objectives tosupport capital markets, it may undermine its role in serving society.

    Full Text Available In classical uncapacitated facility location problems (UFLP the goal is to satisfy requirements of some demand points by setting up some servers, among potential facility locations, such that the total cost including service costs and fixed costs are minimized. In this paper a generalization of UFLP is considered in which some demand points, called self-serving, could be served exclusively by a new server at that point. Numerical experiments show that near optimal solutions are achieved by the proposed method.

  6. Safety class methodology

    1992-01-01

    DOE Order 6430.1A, General Design Criteria (GDC), requires that DOE facilities be evaluated with respect to ''safety class items.'' Although the GDC defines safety class items, it does not provide a methodology for selecting safety class items. The methodology described in this paper was developed to assure that Safety Class Items at the Savannah River Site (SRS) are selected in a consistent and technically defensible manner. Safety class items are those in the highest of four categories determined to be of special importance to nuclear safety and, merit appropriately higher-quality design, fabrication, and industrial test standards and codes. The identification of safety class items is approached using a cascading strategy that begins at the 'safety function' level (i.e., a cooling function, ventilation function, etc.) and proceeds down to the system, component, or structure level. Thus, the items that are required to support a safety function are SCls. The basic steps in this procedure apply to the determination of SCls for both new project activities, and for operating facilities. The GDC lists six characteristics of SCls to be considered as a starting point for safety item classification. They are as follows: 1. Those items whose failure would produce exposure consequences that would exceed the guidelines in Section 1300-1.4, ''Guidance on Limiting Exposure of the Public,'' at the site boundary or nearest point of public access 2. Those items required to maintain operating parameters within the safety limits specified in the Operational Safety Requirements during normal operations and anticipated operational occurrences. 3. Those items required for nuclear criticality safety. 4. Those items required to monitor the release of radioactive material to the environment during and after a Design Basis Accident. Those items required to achieve, and maintain the facility in a safe shutdown condition 6. Those items that control Safety Class Item listed above

  7. Instructional strategies to improve women's attitudes toward science

    Science.gov (United States)

    Newbill, Phyllis Leary

    Although negative attitudes toward science are common among women and men in undergraduate introductory science classes, women's attitudes toward science tend to be more negative than men's. The reasons for women's negative attitudes toward science include lack of self-confidence, fear of association with social outcasts, lack of women role models in science, and the fundamental differences between traditional scientific and feminist values. Attitudes are psychological constructs theorized to be composed of emotional, cognitive, and behavioral components. Attitudes serve functions, including social expressive, value expressive, utilitarian, and defensive functions, for the people who hold them. To change attitudes, the new attitudes must serve the same function as the old one, and all three components must be treated. Instructional designers can create instructional environments to effect attitude change. In designing instruction to improve women's attitudes toward science, instructional designers should (a) address the emotions that are associated with existing attitudes, (b) involve credible, attractive women role models, and (c) address the functions of the existing attitudes. Two experimental instructional modules were developed based on these recommendations, and two control modules were developed that were not based on these recommendations. The asynchronous, web-based modules were administered to 281 undergraduate geology and chemistry students at two universities. Attitude assessment revealed that attitudes toward scientists improved significantly more in the experimental group, although there was no significant difference in overall attitudes toward science. Women's attitudes improved significantly more than men's in both the experimental and control groups. Students whose attitudes changed wrote significantly more in journaling activities associated with the modules. Qualitative analysis of journals revealed that the guidelines worked exactly as predicted

  6. On the losses of dissolved CO(2) during champagne serving.

    Liger-Belair, Gérard; Bourget, Marielle; Villaume, Sandra; Jeandet, Philippe; Pron, Hervé; Polidori, Guillaume

    2010-08-11

    Pouring champagne into a glass is far from being consequenceless with regard to its dissolved CO(2) concentration. Measurements of losses of dissolved CO(2) during champagne serving were done from a bottled Champagne wine initially holding 11.4 +/- 0.1 g L(-1) of dissolved CO(2). Measurements were done at three champagne temperatures (i.e., 4, 12, and 18 degrees C) and for two different ways of serving (i.e., a champagne-like and a beer-like way of serving). The beer-like way of serving champagne was found to impact its concentration of dissolved CO(2) significantly less. Moreover, the higher the champagne temperature is, the higher its loss of dissolved CO(2) during the pouring process, which finally constitutes the first analytical proof that low temperatures prolong the drink's chill and helps it to retain its effervescence during the pouring process. The diffusion coefficient of CO(2) molecules in champagne and champagne viscosity (both strongly temperature-dependent) are suspected to be the two main parameters responsible for such differences. Besides, a recently developed dynamic-tracking technique using IR thermography was also used in order to visualize the cloud of gaseous CO(2) which flows down from champagne during the pouring process, thus visually confirming the strong influence of champagne temperature on its loss of dissolved CO(2).

    That sciences are guided by explicit and implicit ties to their surrounding social world is not new. Jaan Valsiner fills in the wide background of scholarship on the history of science, the recent focus on social studies of sciences, and the cultural and cognitive analyses of knowledge making....... The theoretical scheme that he uses to explain the phenomena of social guidance of science comes from his thinking about processes of development in general—his theory of bounded indeterminacy—and on the relations of human beings with their culturally organized environments. Valsiner examines reasons for the slow...... and nonlinear progress of ideas in psychology as a science at the border of natural and social sciences. Why is that intellectual progress occurs in different countries at different times?

    Increasing students' earth science literacy, especially those at Minority Serving Institutions (MSIs), is a primary goal of the American Meteorological Society (AMS). Through the NSF-supported AMS Weather Studies and AMS Ocean Studies Diversity workshops for Historically Black College and Universities, Hispanic Serving Institutions, Tribal Colleges and Universities, Alaska Native, and Native Hawaiian Serving Institutions, AMS has brought meteorology and oceanography courses to more students. These workshops trained and mentored faculty implementing AMS Weather Studies and AMS Ocean Studies. Of the 145 institutions that have participated in the AMS Weather Studies Diversity Project, reaching over 13,000 students, it was the first meteorology course offered for more than two-thirds of the institutions. As a result of the AMS Ocean Studies Diversity Project, 75 institutions have offered the course to more than 3000 students. About 50 MSIs implemented both the Weather and Ocean courses, improving the Earth Science curriculum on their campuses. With the support of NSF and NASA, and a partnership with Second Nature, the organizing entity behind the American College and University President's Climate Commitment (ACUPCC), the newest professional development workshop, AMS Climate Studies Diversity Project will recruit MSI faculty members through the vast network of Second Nature's more than 670 signatories. These workshops will begin in early summer 2012. An innovative approach to studying climate science, AMS Climate Studies explores the fundamental science of Earth's climate system and addresses the societal impacts relevant to today's students and teachers. The course utilizes resources from respected organizations, such as the IPCC, the US Global Change Research Program, NASA, and NOAA. In addition, faculty and students learn about basic climate modeling through the AMS Conceptual Energy Model. Following the flow of energy in a clear, simplified model from space to

  15. Prediction of protein structural classes by Chou's pseudo amino acid composition: approached using continuous wavelet transform and principal component analysis.

    Li, Zhan-Chao; Zhou, Xi-Bin; Dai, Zong; Zou, Xiao-Yong

    2009-07-01

    A prior knowledge of protein structural classes can provide useful information about its overall structure, so it is very important for quick and accurate determination of protein structural class with computation method in protein science. One of the key for computation method is accurate protein sample representation. Here, based on the concept of Chou's pseudo-amino acid composition (AAC, Chou, Proteins: structure, function, and genetics, 43:246-255, 2001), a novel method of feature extraction that combined continuous wavelet transform (CWT) with principal component analysis (PCA) was introduced for the prediction of protein structural classes. Firstly, the digital signal was obtained by mapping each amino acid according to various physicochemical properties. Secondly, CWT was utilized to extract new feature vector based on wavelet power spectrum (WPS), which contains more abundant information of sequence order in frequency domain and time domain, and PCA was then used to reorganize the feature vector to decrease information redundancy and computational complexity. Finally, a pseudo-amino acid composition feature vector was further formed to represent primary sequence by coupling AAC vector with a set of new feature vector of WPS in an orthogonal space by PCA. As a showcase, the rigorous jackknife cross-validation test was performed on the working datasets. The results indicated that prediction quality has been improved, and the current approach of protein representation may serve as a useful complementary vehicle in classifying other attributes of proteins, such as enzyme family class, subcellular localization, membrane protein types and protein secondary structure, etc.

  16. Group-Effort Applied Research (GEAR): Expanding Opportunities for Undergraduate Research Through Original, Class-Based Research Projects

    Science.gov (United States)

    Moore, Sean D.; Teter, Ken

    2014-01-01

    Undergraduate research clearly enriches the educational development of participating students, but these experiences are limited by the inherent inefficiency of the standard one student - one mentor model for undergraduate research. Group-Effort Applied Research (GEAR) was developed as a strategy to provide substantial numbers of undergraduates with meaningful research experiences. The GEAR curriculum delivers concept-driven lecture material and provides hands-on training in the context of an active research project from the instructor's lab. Because GEAR is structured as a class, participating students benefit from intensive, supervised research training that involves a built-in network of peer support and abundant contact with faculty mentors. The class format also ensures a relatively standardized and consistent research experience. Furthermore, meaningful progress toward a research objective can be achieved more readily with GEAR than with the traditional one student - one mentor model of undergraduate research because sporadic mistakes by individuals in the class are overshadowed by the successes of the group as a whole. Three separate GEAR classes involving three distinct research projects have been offered to date. In this paper, we provide an overview of the GEAR format and review some of the recurring themes for GEAR instruction. We propose GEAR can serve as a template to expand student opportunities for life science research without sacrificing the quality of the mentored research experience. PMID:24898007

    2015-12-01

    Full Text Available The problem of translation in foreign language classes cannot be dealt with unless we attempt to make an overview of what translation meant for language teaching in different periods of language pedagogy. From the translation-oriented grammar-translation method through the complete ban on translation and mother tongue during the times of the audio-lingual approaches, we have come today to reconsider the role and status of translation in ESL classes. This article attempts to advocate for translation as a useful ESL class activity, which can completely fulfil the requirements of communicativeness. We also attempt to identify some activities and games, which rely on translation in some books published in the 1990s and the 2000s.

  18. A study of the effects of gender and different instructional media (computer-assisted instruction tutorials vs. textbook) on student attitudes and achievement in a team-taught integrated science class

    Science.gov (United States)

    Eardley, Julie Anne

    The purpose of this study was to determine the effect of different instructional media (computer assisted instruction (CAI) tutorial vs. traditional textbook) on student attitudes toward science and computers and achievement scores in a team-taught integrated science course, ENS 1001, "The Whole Earth Course," which was offered at Florida Institute of Technology during the Fall 2000 term. The effect of gender on student attitudes toward science and computers and achievement scores was also investigated. This study employed a randomized pretest-posttest control group experimental research design with a sample of 30 students (12 males and 18 females). Students had registered for weekly lab sessions that accompanied the course and had been randomly assigned to the treatment or control group. The treatment group used a CAI tutorial for completing homework assignments and the control group used the required textbook for completing homework assignments. The Attitude toward Science and Computers Questionnaire and Achievement Test were the two instruments administered during this study to measure students' attitudes and achievement score changes. A multivariate analysis of covariance (MANCOVA), using hierarchical multiple regression/correlation (MRC), was employed to determine: (1) treatment versus control group attitude and achievement differences; and (2) male versus female attitude and achievement differences. The differences between the treatment group's and control group's homework averages were determined by t test analyses. The overall MANCOVA model was found to be significant at p factor set independent variables separately resulted in gender being the only variable that significantly contributed in explaining the variability in a dependent variable, attitudes toward science and computers. T test analyses of the homework averages showed no significant differences. Contradictory to the findings of this study, anecdotal information from personal communication, course

    Introductory astronomy courses often serve as terminal science courses for non-science majors and present an opportunity to assess non future scientists’ attitudes towards science as well as basic scientific knowledge and scientific analysis skills that may remain unchanged after college. Through a series of studies, we have been able to evaluate students’ basic science knowledge, attitudes towards science, quantitative literacy, and informational literacy. In the Fall of 2015, we conducted a case study of a single class administering all relevant surveys to an undergraduate class of 20 students. We will present our analysis of trends of each of these studies as well as the comparison case study. In general we have found that students basic scientific knowledge has remained stable over the past quarter century. In all of our studies, there is a strong relationship between student attitudes and their science and quantitative knowledge and skills. Additionally, students’ information literacy is strongly connected to their attitudes and basic scientific knowledge. We are currently expanding these studies to include new audiences and will discuss the implications of our findings for instructors.

    2012-03-01

    I have been involved in research on collaborative activities for improving the quality of teaching and learning high school science. Initially the collaborative activities we researched involved the uses of coteaching and cogenerative dialogue in urban middle and high schools in Philadelphia and New York (currently I have active research sites in New York and Brisbane, Australia). The research not only transformed practices but also produced theories that informed the development of additional collaborative activities and served as interventions for research and creation of heuristics for professional development programs and teacher certification courses. The presentation describes a collage of collaborative approaches to teaching and learning science, including coteaching, cogenerative dialogue, radical listening, critical reflection, and mindful action. For each activity in the collage I provide theoretical frameworks and empirical support, ongoing research, and priorities for the road ahead. I also address methodologies used in the research, illustrating how teachers and students collaborated as researchers in multilevel investigations of teaching and learning and learning to teach that included ethnography, video analysis, and sophisticated analyses of the voice, facial expression of emotion, eye gaze, and movement of the body during classroom interactions. I trace the evolution of studies of face-to-face interactions in science classes to the current focus on emotions and physiological aspects of teaching and learning (e.g., pulse rate, pulse strength, breathing patterns) that relate to science participation and achievement.

    The astronomy outreach initiative, Multicultural Milky Way, partners the School of Earth and Space Exploration (SESE) at Arizona State University (ASU) with under-served populations in Arizona in learning about our Milky Way and other galaxies. Arizona is home to many diverse populations with rich cultural histories such as Mayan, Navajo, and Apache. Linking astronomy practiced by one’s indigenous culture to that of Western astronomy may increase the interest in science. Through multicultural planetarium shows and associated hands-on activities, under-served students and families will learn how the Milky Way is represented in different cultures and about the science of galaxies. New planetarium shows using the Mesa Community College (MCC) Digital Planetarium and STARLAB portable planetarium explore how the Milky Way is interpreted in different cultures. STARLAB shows and associated new hands-on activities have been featured during school visits, teacher trainings, and Community Astronomy Nights around Arizona. For authentic assessment, evaluation techniques and procedures were developed.

    Climate change research and innovations in weather forecasting rely more and more on (Big) data. Besides increasing data from traditional sources (such as observation networks, radars and satellites), the use of open data, crowd sourced data and the Internet of Things (IoT) is emerging. To deploy these sources of data optimally in our services and products, KNMI has established a DataLab to serve data-driven innovations in collaboration with public and private sector partners. Big data management, data integration, data analytics including machine learning and data visualization techniques are playing an important role in the DataLab. Cross-domain data-driven innovations that arise from public-private collaborative projects and research programmes can be explored, experimented and/or piloted by the KNMI DataLab. Furthermore, advice can be requested on (Big) data techniques and data sources. In support of collaborative (Big) data science activities, scalable environments are offered with facilities for data integration, data analysis and visualization. In addition, Data Science expertise is provided directly or from a pool of internal and external experts. At the EGU conference, gained experiences and best practices are presented in operating the KNMI DataLab to serve data-driven innovations for weather and climate applications optimally.

  6. Reflections on implementing several models of teaching in a high school biology class

    Science.gov (United States)

    Baldwin, Michael E.

    This research investigates the challenges faced in enacting instructional models that previous research has found to foster student learning. In order to complete this study, the researcher documented, through a strategy of reflective practice, his return to teaching high school science after having served for a time as a science specialist and instructional coach. The study develops quality personal insights and questions that may be used by other educators and researchers to investigate the enactment of these different models and strategies. The research is limited to the spring of the 2010 school year and use notes, journals, and planner documents from the 2008--2009 school year. In order to appreciate complex interactions, triangulation was made through dovetailing personal observations with requested observations of the campus assistant principal, the district science specialist, and an out of district observer. Also, a short questionnaire administered to the students in these classes. Throughout this study, the researcher demonstrates that it is feasible to use these models. However, such external factors as imposed curriculum and standardized testing play a large role in everyday decision making of this particular teacher. The sheer amount of content to be covered under the Texas Essential Knowledge and Skills (TEKS) also influenced instructional decisions that were made. Choices about what strategy to use resided mainly within the teacher/researcher and were governed and affected mostly by his interactions with students and professional judgments about what would both bolster student understanding and help students score well on the Texas Assessment of Knowledge and Skills (TAKS).

    Full Text Available The scores obtained by the military students are very important as a lot of opportunities depend on them: the choice of the branch, selection for different in and off-campus activities, the appointment to the workplace and so on. A qualifier, regardless of its form of effective expression, can make a difference in a given context of issuing a value judgment, in relation to the student's performance assessment. In our research we tried to find out what motives students, what determines them to get actively involved in the tasks they are given and the ways we can improve their participation in classes and assignments. In order to have an educated generation we need to have not only well prepared teachers but ones that are open-minded, flexible and in pace with the methodological novelties that can improve the teaching learning process in class. Along the years we have noticed that in classes where students constituted a cohesive group with an increasing degree of interaction between members, the results were better than in a group that did not appreciate team-work. In this article we want to highlight the fact that a teacher can bring to class the appropriate methods and procedures can contribute decisively to the strengthening of the group cohesion and high scores.

    Full Text Available The global world is gradually becoming a world of separated crowds despite the artificial wire and wireless connection through television and the Internet. Crowds remain a prevailing subject of research in different social studies, and the research of changes in the psychological structure of crowds and their characteristics is still of primary interest. The main focus of the research is on the interpretation of the results of the research paper about a special separated crowd called audience. It was observed how students, constituting the crowd, perceive a crowd on video. The observation was focused on the research of emotional contagion and mood in the crowd serving as audience. While watching a mass event on a big screen, the crowd serving as audience emotionally converges with someone else, in our case with public speakers.

    Full Text Available Latinos remain the largest US population with limited health literacy (Andrulis D.P. & Brach, 2007. Concerned with how local media can meet the information needs of underserved audiences, we interviewed Latinas who were pregnant or mothers of young children living in a Spanish speaking community, and surveyed 33 local health professionals. Findings are that Latina women’s most common source of health information was family and friends. They said they tune to Spanish television and radio programs, but gave low grades to news media for health information. Medical professionals agreed that Latinas generally get their health information through friends and family, and rated the media poorly in terms of serving Latinas’ needs. Since the data indicate that the local news media are not serving Latinas’ health information needs as much as they could, we offer recommendations to potentially exploit new technological affordances and suggest expansion of conventional definitions of health literacy.

  17. Adeus à classe trabalhadora?

    Directory of Open Access Journals (Sweden)

    Geoff Eley

    2013-12-01

    Full Text Available No início da década de 1980, a política centrada em classes da tradição socialista estava em crise, e comentadores importantes adotaram tons apocalípticos. No final da década, a esquerda permanecia profundamente dividida entre os advogados da mudança e os defensores da fé. Em meados dos anos 1990, os primeiros tinham, de modo geral, ganhado a batalha. O artigo busca apresentar essa mudança contemporânea não como a 'morte da classe', mas como o desa­parecimento de um tipo particular de ­sociedade de classes, marcado pelo ­processo de formação da classe trabalhadora entre os anos 1880 e 1940 e pelo alinhamento político daí resultante, atingindo seu apogeu na construção social-democrata do acordo do pós-guerra. Quando mudanças de longo prazo na economia se combinaram com o ataque ao keynesianismo na política de recessão a partir de meados da década de 1970, a unidade da classe trabalhadora deixou de estar disponível da forma antiga e bastante utilizada, como o terreno natural da política de esquerda. Enquanto uma coletividade dominante da classe trabalhadora entrou em declínio, outra se corporificou de modo lento e desigual para tomar o lugar daquela. Mas a unidade operacional dessa nova agregação da classe trabalhadora ainda está, em grande parte, em formação. Para recuperar a eficácia política da tradição socialista, alguma nova visão de agência política coletiva será necessária, uma visão imaginativamente ajustada às condições emergentes da produção e acumulação capitalista no início do século XXI.

  1. Social class, sense of control, and social explanation.

    Science.gov (United States)

    Kraus, Michael W; Piff, Paul K; Keltner, Dacher

    2009-12-01

    Lower social class is associated with diminished resources and perceived subordinate rank. On the basis of this analysis, the authors predicted that social class would be closely associated with a reduced sense of personal control and that this association would explain why lower class individuals favor contextual over dispositional explanations of social events. Across 4 studies, lower social class individuals, as measured by subjective socioeconomic status (SES), endorsed contextual explanations of economic trends, broad social outcomes, and emotion. Across studies, the sense of control mediated the relation between subjective SES and contextual explanations, and this association was independent of objective SES, ethnicity, political ideology, and self-serving biases. Finally, experimentally inducing a higher sense of control attenuated the tendency for lower subjective SES individuals to make more contextual explanations (Study 4). Implications for future research on social class as well as theoretical distinctions between objective SES and subjective SES are discussed.

  2. Alyeska/SERVS technological innovations for oil spill response

    Hillman, S.O.

    1996-01-01

    An overview of technological innovations in spill response by Alyeska Pipeline Service Company/SERVS (ship escort response vessel system), was presented. The company has developed a number of spill response techniques which have needed new strategies and modified equipment for fulfillment of the Prince William Sound Tanker Oil Discharge Prevention and Contingency Plan. One of the strategies was the training of personnel to be ready to deploy massive quantities of equipment on short notice to potential spill sites over an 11,000 square mile water body with more than 3,200 miles of wilderness shoreline. Specific response equipment and decision-making tools have been developed in direct support of large scale programs. Along with oil slick tracking buoys and mini barges, SERVS has developed high capacity skimmers with recovery capacities approaching 2,000 to 3,000 barrels of liquid per hour and strategy boom-towing vessels which divert oil into a long U shaped containment boom. SERVS fishing vessel program, hatchery protection and remote response center equipment program, and wildlife treatment facilities were also described. 10 refs., 13 figs

    Full Text Available Drawing upon 15 qualitative interviews with early- to mid-career faculty (seven men and eight women at Minority Serving Institutions (MSIs, this study examines the diverse motivations and paths those faculty members have taken to becoming professors at their respective institutions. The faculty come from a range of MSIs (Historically Black Colleges and Universities, Hispanic Serving Institutions, Asian American and Native American Pacific Islander Serving Institutions, and Predominantly Black Institutions across the country and represent a broad spectrum of disciplines. This study sheds light on factors that guide their choices of discipline and entrance into the faculty ranks at MSIs. Social cognitive career theory (SCCT was used as a lens during qualitative coding and analysis in order to develop the findings, which reveal that (1 teaching, activism, and community uplift were primary motivators to enter the professoriate; (2 supportive environmental factors, including single individuals, proved pivotal in influencing faculty to take these roles; and (3 career transitions into the academy were spurred by learning experiences that revealed disciplinary and teaching interests. The findings suggest that MSIs attract community-oriented individuals to their faculty positions, and that colleges and universities interested in diversifying their faculties should craft such roles in ways that are appealing to the populations that they are trying to recruit and retain.

    "Earth2Class" (E2C) is a unique program offered through the Lamont-Doherty Earth Observatory of Columbia University. It connects research scientists, classroom teachers, middle and high school students, and others in ways that foster broader outreach of cutting-edge discoveries. One key component are Saturday workshops offered during the school year. These provide investigators with a tested format for sharing research methods and results. Teachers and students learn more about "real"science than what is found in textbooks. They discover that Science is exciting, uncertain, and done by people not very different from themselves. Since 1998, we have offered more than 170 workshops, partnering with more than 90 LDEO scientists. E2C teachers establishe links with scientists that have led to participation in research projects, the LDEO Open House, and other programs. Connections developed between high school students and scientists resulted in authentic science research experiences. A second key component of the project is the E2C website, https://earth2class.org/site/. We provide archived versions of monthly workshops. The website hosts a vast array of resources geared to support learning Earth Science and other subjects. Resources created through an NSF grant to explore strategies which enhance Spatial Thinking in the NYS Regents Earth Science curriculum are found at https://earth2class.org/site/?page_id=2957. The site is well-used by K-12 Earth Science educators, averaging nearly 70k hits per month. A third component of the E2C program are week-long summer institutes offering opportunities to enhance content knowledge in weather and climate; minerals, rocks, and resources; and astronomy. These include exploration of strategies to implement NGSS-based approaches within the school curriculum. Participants can visit LDEO lab facilities and interact with scientists to learn about their research. In the past year, we have begun to create a "satellite" E2C program at UFVJM

    2015-12-01

    For more than 30 years, the Research Applications Laboratory (RAL) of the National Center for Atmospheric Research (NCAR) has conducted fundamental and applied research focused on developing decision support tools spanning multiple end-user groups representing a variety of economic sectors. Technology transfer is a primary mission of the laboratory where innovation is a key attribute and multidisciplinary research and development are the norm. Application areas include, aviation, surface transportation, wind and solar energy prediction, climate, weather and health, numerical weather prediction, biological and chemical plume dispersion for homeland security, flood prediction and water resource management, soil condition and crop maturity prediction among other application areas. The majority of the developed capabilities have been operationalized by the public, private, and academic sectors. Several commercial companies have been successfully formed around the technologies (e.g., Weather Information Technologies, Inc., Peak Weather Resources, Inc., and Global Weather Corporation) and many existing companies have improved their products by utilizing the RAL-developed weather system advancements (The Weather Channel, WSI, Schneider Electric, Xcel Energy, United Airlines, Vaisala, Panasonic, Idaho Power, etc.). The economic benefit estimates of implementing these technologies have ranged from billions of dollars in avoided commercial aircraft accidents over the last 30 years to 10s of millions of dollars of annual savings by state departments of transportation via more efficient ice and snow maintenance operations. Research and development at RAL is connected to the Broader Impacts Criterion of NSF and its focus on research that results in significant economic or societal impact. This talk will describe our research-to-operations process and discuss several technology transfer examples that have led to commercial opportunities.

    Full Text Available Storytelling is one of the oldest ways of education and oral tradition that is continuously being used to transfer the previous nation‘s cultures, tradition and customs. It constructs a bridge between the new and the old. Storytelling in EFL classes usually provides a meaningful context, interesting atmosphere and is used as a tool to highly motivate students. Although it seems to be mostly based on speaking, it is used to promote other skills such as writing, reading, and listening. Storytelling is mainly regarded to be grounded on imitation and repetition; nevertheless many creative activities can be implemented in the classroom since this method directs learners to use their imaginations. This study discusses the importance of storytelling as a teaching method, and it outlines the advantages of storytelling in EFL classes.

    The After-School Astronomy Project (ASAP) is a comprehensive initiative to promote the pursuit of science learning among underrepresented youth. To this end ASAP specifically aims at building the capacity of urban community-based centers to deliver innovative science out-of-school programming to their youth. ASAP makes use of a modular curriculum consisting of a combination of hands-on activities and youth-led explorations of the night sky using MicroObservatory. Through project-based investigations students reinforce learning in astronomy and develop an understanding of science as inquiry, while also develop communication and computer skills. Through MicroObservatory students gain access to a network of educational telescopes, that they control over the Internet, software analysis tools and an online community of users. An integral part of ASAP is to provide professional development opportunities for after-school workers. This promotes a self-sustainable implementation of ASAP long-term and fosters the creation of a cadre of after-school professionals dedicated to facilitating science-based programs.

    Objective. To examine students' self-perceptions at different stages in a pharmacy curriculum of competence related to serving culturally diverse patients and to compare self-reported competence of a student cohort near the beginning and end of the degree program. Methods. Student perceptions across four pharmacy class years were measured in a cross-sectional survey, with a follow-up longitudinal survey of one cohort three years later. Results. Based on an 81.9% response rate (537/656), scores showed no attitude changes. Reported knowledge, skills, comfort in clinical encounters, and curricular preparedness increased across program years. Fourth-year (P4) pharmacy students reported the highest scores. Scores differed by gender, age, and race/ethnicity. Students in the fourth year scored lower on importance of diversity training. Conclusion. Improved perceptions of readiness (ie, knowledge and behavior) to serve diverse groups suggest the curriculum impacts these constructs, while the invariance of student attitudes and association of self-reports with programmatic outcomes warrant further investigation.

  2. [Social classes and poverty].

    Benach, Joan; Amable, Marcelo

    2004-05-01

    Social classes and poverty are two key social determinants fundamental to understand how disease and health inequalities are produced. During the 90's in Spain there has been a notable oscillation in the inequality and poverty levels, with an increase in the middle of the decade when new forms of social exclusion, high levels of unemployment and great difficulties in accessing the labour market, especially for those workers with less resources, emerged. Today society is still characterized by a clear social stratification and the existence of social classes with a predominance of high levels of unemployment and precarious jobs, and where poverty is an endemic social problem much worse than the EU average. To diminish health inequalities and to improve the quality of life will depend very much on the reduction of the poverty levels and the improvement of equal opportunities and quality of employment. To increase understanding of how social class and poverty affect public health, there is a need to improve the quality of both information and research, and furthermore planners and political decision makers must take into account those determinants when undertaking disease prevention and health promotion.

  3. Restaurant Policies and Practices for Serving Raw Fish in Minnesota.

    Hedeen, Nicole

    2016-10-01

    The number of restaurants serving sushi within Minnesota is continuously increasing. The practices and protocols of serving raw fish are complex and require detailed planning to ensure that food served to patrons will not cause illness. Although the popularity of sushi is increasing, there is a lack of research on food safety issues pertaining to preparation of raw fish and sushi rice. To address this gap, the Minnesota Department of Health Environmental Health Specialists Network Food program collected descriptive data on restaurant practices and policies concerning the service of raw fish and sushi rice in 40 Minnesota restaurants. At each restaurant, a specialist interviewed a restaurant manager, conducted an observation of the sushi prep areas in the restaurant kitchen, and reviewed parasite destruction letters and invoices from fish supplier(s). Over half of the restaurants (59%) were missing one or more of the parasite destruction letters from their fish supplier(s) guaranteeing that fish had been properly frozen to the time and temperature requirements in the Minnesota Food Code. A total of 42 parasite destruction letters from suppliers were observed; 10% were considered "adequate" letters. The majority of the letters were missing details pertaining to the types of fish frozen, the length of time fish were frozen, or details on what temperatures fish were held frozen or a combination of all three. Most restaurants were using time as a public health control for their sushi rice. For those restaurants using time as a public health control, 26% had a written procedure on-site, and approximately 53% were keeping track of time. Bare hand contact during sushi prep was observed in 17% of restaurants, and in more than 40% of the restaurants, at least one fish was mislabeled on the menu. Findings from this study indicate that many Minnesota restaurants are not complying with the Food Code requirements pertaining to parasite destruction for the service of raw fish or

  4. Understanding the Prevalence of Geo-Like Degree Programs at Minority Serving Institutions

    Science.gov (United States)

    McDaris, J. R.; Manduca, C. A.; Larsen, K.

    2014-12-01

    Over the decade 2002-12, the percentage of students from underrepresented minorities (URM) graduating with geoscience degrees has increased by 50%. In 2012, of the nearly 6,000 geoscience Bachelor's degrees, 8% were awarded to students from URM. But that same year across all of STEM, 18% of Bachelors went to these students, and URM made up 30% of the US population overall. Minority Serving Institutions (MSIs) play an important role in increasing the diversity of geoscience graduates where there are appropriate degree programs or pathways to programs. To better understand opportunities at these institutions, the InTeGrate project collected information on degree programs at MSIs. A summer 2013 survey of websites for three types of MSIs confirmed that, while stand-alone Geology, Geoscience, or Environmental Science departments are present, there are a larger number of degree programs that include elements of geoscience or related disciplines (geography, GIS, etc.) offered in interdisciplinary departments (e.g. Natural Sciences and Math) or cognate science departments (Physics, Engineering, etc.). Approximately one-third of Hispanic Serving Institutions and Tribal Colleges and one-fifth of Historically Black Colleges and Universities offer at least one degree that includes elements of geoscience. The most common programs were Geology and Environmental Science (94 and 88 degrees respectively), but 21 other types of program were also found. To better profile the nature of these programs, 11 interviews were conducted focusing on strategies for attracting, supporting, and preparing minority students for the workforce. In conjunction with the February 2014 Broadening Access to the Earth and Environmental Sciences workshop, an additional 6 MSI profiles were obtained as well as 22 profiles from non-MSIs. Several common strategies emerge: Proactive marketing and outreach to local high schools and two-year colleges Community building, mentoring and advising, academic support

    Recent reform efforts in science education focus on scientific literacy for all citizens. In order to be scientifically literate, an individual must have informed understandings of nature of science (NOS), scientific inquiry, and science content matter. This study specifically focused on Science Olympiad students' understanding of NOS as one piece of scientific literacy. Research consistently shows that science students do not have informed understandings of NOS (Abd-El-Khalick, 2002; Bell, Blair, Crawford, and Lederman, 2002; Kilcrease and Lucy, 2002; Schwartz, Lederman, and Thompson, 2001). However, McGhee-Brown, Martin, Monsaas and Stombler (2003) found that Science Olympiad students had in-depth understandings of science concepts, principles, processes, and techniques. Science Olympiad teams compete nationally and are found in rural, urban, and suburban schools. In an effort to learn from students who are generally considered high achieving students and who enjoy science, as opposed to the typical science student, the purpose of this study was to investigate Science Olympiad students' understandings of NOS and the experiences that formed their understandings. An interpretive, qualitative, case study method was used to address the research questions. The participants were purposefully and conveniently selected from the Science Olympiad team at a suburban high school. Data collection consisted of the Views of Nature of Science -- High School Questionnaire (VNOS-HS) (Schwartz, Lederman, & Thompson, 2001), semi-structured individual interviews, and a focus group. The main findings of this study were similar to much of the previous research in that the participants had informed understandings of the tentative nature of science and the role of inferences in science, but they did not have informed understandings of the role of human imagination and creativity, the empirical nature of science, or theories and laws.

  9. How youth-serving organizations enable acquaintance molesters.

    2014-10-01

    In recent years, some of the country's most prominent institutions have been ensnared in child sex abuse scandals. While each abuse incident features its own particular circumstances, institutions that have been the subject of these scandals have displayed similar patterns of organizational behavior that allowed molesting to occur and molesters to escape accountability. We can learn from those patterns to better understand and combat acquaintance molestation in youth-serving organizations. Although sex abuse is an inherent risk in youth work, American youth-serving organizations have responded to this risk largely on a case-by-case basis after abuse incidents have been revealed, rather than through proactive strategies to reduce the risk of abuse and to respond effectively to allegations. An examination of abuse scandals reveals common patterns of behavior among paid and volunteer staff in organizations that did not enact comprehensive, proactive strategies: Faith in the organiation blinded staff to the liklihood of abuse; organizations kept workers ignorant about the extent of the abuse problem; when abuse accusations arose, staff gave the benefit of the doubt to the adult; when abuse accusations were confirmed, staffers did not know how to respond; and not knowing how to resopnd, staff prioritized the protection of the organization. As a result, child molesters have been falsely exonerated or not held accountable, abused children have been disbelieved, and abuse has continued. These organizations inadvertently achieved the opposite of their missions: They enabled child molesters at the expense of children. © The Author(s) 2014.

  10. Self-serving bias effects on job analysis ratings.

    2012-01-01

    The purpose of this study was to investigate whether worker-oriented job analysis importance ratings were influenced by subject matter experts' (SME) standing (as measured by self-rated performance) on a competency. This type of relationship (whereby SMEs indicate that the traits they have are important for successful job performance) is an example of the self-serving bias (which is widely described in the social cognition literature and rarely described in the industrial/organizational psychology literature). An archival dataset covering 57 clerical and technical occupations with 26,682 participants was used. Support was found for the relationship between self-rated performance and importance ratings. Significant relationships (typically in the .30s) were observed for all 31 competencies that were studied. Controls were taken to account for common method bias and differences in the competencies required for each of the 57 occupations. Past research has demonstrated the effects of the self-serving bias on personality-based job analysis ratings. This study was the first to extend these findings to traditional job analysis, which covers other competencies in addition to personality. In addition, this study is the first to use operational field data instead of laboratory data.

  11. Curricular constraints, high-stakes testing and the reality of reform in high school science classrooms

    Science.gov (United States)

    Coble, Jennifer

    Through a series of open-ended interviews, this study investigated the beliefs of six third year high school science teachers about how they implement science education reform ideals in their practice and the contextual challenges they face as they attempt to implement reform. The teachers argue that the lack of connection between their curricula and students' lives serves as a significant obstacle to them utilizing more inquiry-based and student-centered strategies. In their science classes that are not subject to a high stakes exam, the teachers shared instances where they engage students in inquiry by refraining the focus of their curricula away from the decontextualized factual information and onto how the information relates to human experience. In their science classes subject to a high stakes test, however, the teachers confessed to feeling no choice but to utilize more teacher-centered strategies focused on information transmission. This study provides an in depth analysis of how the presence of high stakes tests discourages teachers from utilizing reform based teaching strategies within high school science classrooms.

  12. The perceptions of inquiry held by greater Houston area science supervisors

    Science.gov (United States)

    Aoki, Jon Michael

    The purpose of this study was to describe the perceptions of inquiry held by responding greater Houston area science supervisors. Leading science organizations proposed that students might be better served if students are mentally and physically engaged in the process of finding out about natural phenomena rather than by didactic modes of teaching and learning. During the past fifty years, inquiry-based instruction has become a significant theme of new science programs. Students are more likely to make connections between classroom exercises and their personal lives through the use of inquiry-based instruction. Learning becomes relevant to students. Conversely, traditional science instruction often has little or no connection to students' everyday lives (Papert, 1980). In short, inquiry-based instruction empowers students to become independent thinkers. The utilization of inquiry-based instruction is essential to a successful reform in science education. However, a reform's success is partly determined by the extent to which science supervisors know and understand inquiry and consequently promote its integration in the district's science curricula. Science supervisors have the role of providing curriculum and instructional support to science teachers and for implementing science programs. There is a fundamental need to assess the perceptions of inquiry held by greater Houston area science supervisors. Science supervisor refers to a class of job titles that include department chairperson, science specialist, science consultant, and science coordinator. The target population was greater Houston area science supervisors in Texas. This study suggests that there are three major implications for educational practice. First, there is the implication that responding greater Houston area science supervisors need an inclusive perception of inquiry. Second, responding greater Houston area science supervisors' perception of inquiry may affect the perceptions and understandings

  19. Class prediction for high-dimensional class-imbalanced data

    Directory of Open Access Journals (Sweden)

    Lusa Lara

    2010-10-01

    Full Text Available Abstract Background The goal of class prediction studies is to develop rules to accurately predict the class membership of new samples. The rules are derived using the values of the variables available for each subject: the main characteristic of high-dimensional data is that the number of variables greatly exceeds the number of samples. Frequently the classifiers are developed using class-imbalanced data, i.e., data sets where the number of samples in each class is not equal. Standard classification methods used on class-imbalanced data often produce classifiers that do not accurately predict the minority class; the prediction is biased towards the majority class. In this paper we investigate if the high-dimensionality poses additional challenges when dealing with class-imbalanced prediction. We evaluate the performance of six types of classifiers on class-imbalanced data, using simulated data and a publicly available data set from a breast cancer gene-expression microarray study. We also investigate the effectiveness of some strategies that are available to overcome the effect of class imbalance. Results Our results show that the evaluated classifiers are highly sensitive to class imbalance and that variable selection introduces an additional bias towards classification into the majority class. Most new samples are assigned to the majority class from the training set, unless the difference between the classes is very large. As a consequence, the class-specific predictive accuracies differ considerably. When the class imbalance is not too severe, down-sizing and asymmetric bagging embedding variable selection work well, while over-sampling does not. Variable normalization can further worsen the performance of the classifiers. Conclusions Our results show that matching the prevalence of the classes in training and test set does not guarantee good performance of classifiers and that the problems related to classification with class

    Social class meaningfully impacts individuals' life outcomes and daily interactions, and the mere perception of one's socioeconomic standing can have significant ramifications. To better understand how people infer others' social class, we therefore tested the legibility of class (operationalized as monetary income) from facial images, finding across 4 participant samples and 2 stimulus sets that perceivers categorized the faces of rich and poor targets significantly better than chance. Further investigation showed that perceivers categorize social class using minimal facial cues and employ a variety of stereotype-related impressions to make their judgments. Of these, attractiveness accurately cued higher social class in self-selected dating profile photos. However, only the stereotype that well-being positively relates to wealth served as a valid cue in neutral faces. Indeed, neutrally posed rich targets displayed more positive affect relative to poor targets and perceivers used this affective information to categorize their social class. Impressions of social class from these facial cues also influenced participants' evaluations of the targets' employability, demonstrating that face-based perceptions of social class may have important downstream consequences.

  1. Extracting UML Class Diagrams from Object-Oriented Fortran: ForUML

    Directory of Open Access Journals (Sweden)

    Aziz Nanthaamornphong

    2015-01-01

    Full Text Available Many scientists who implement computational science and engineering software have adopted the object-oriented (OO Fortran paradigm. One of the challenges faced by OO Fortran developers is the inability to obtain high level software design descriptions of existing applications. Knowledge of the overall software design is not only valuable in the absence of documentation, it can also serve to assist developers with accomplishing different tasks during the software development process, especially maintenance and refactoring. The software engineering community commonly uses reverse engineering techniques to deal with this challenge. A number of reverse engineering-based tools have been proposed, but few of them can be applied to OO Fortran applications. In this paper, we propose a software tool to extract unified modeling language (UML class diagrams from Fortran code. The UML class diagram facilitates the developers' ability to examine the entities and their relationships in the software system. The extracted diagrams enhance software maintenance and evolution. The experiments carried out to evaluate the proposed tool show its accuracy and a few of the limitations.

    Rhode Island`s landfill and adjacent materials recovery facility (MRF) in Johnston, both owned by the quasi-public Rhode Island Resource Recovery Corp. (RIRRC, Johnston), serve the entire state. The $12-million recycling facility was built in 1989 next to the state`s sole landfill, the Central Landfill, which accepts only in-state trash. The MRF is operated for RIRRC by New England CRInc. (Hampton, N.H.), a unit of Waste Management, Inc. (WMI, Oak Brook, Ill.). It handles a wide variety of materials, from the usual newspaper, cardboard, and mixed containers to new streams such as wood waste, scrap metal, aseptic packaging (milk and juice boxes), and even textiles. State municipalities are in the process of adding many of these new recyclable streams into their curbside collection programs, all of which feed the facility.

    The Federal Energy Management Program (FEMP) in the U.S. Department of Energy (DOE) is targeting Federal facilities serving Native American populations for cost-effective renewable energy projects. These projects not only save energy and money, they also provide economic opportunities for the Native Americans who assist in producing, installing, operating, or maintaining the renewable energy systems obtained for the facilities. The systems include solar heating, solar electric (photovoltaic or PV), wind, biomass, and geothermal energy systems. In fiscal years 1998 and 1999, FEMP co-funded seven such projects, working with the Indian Health Service in the U.S. Department of Health and Human Services, the Bureau of Indian Affairs in the U.S. Department of the Interior, and their project partners. The new renewable energy systems are helping to save money that would otherwise be spent on conventional energy and reduce the greenhouse gases associated with burning fossil fuels

  7. Can gene fusions serve for fingerprints of radiogenic cancers?

    International Nuclear Information System (INIS)

    Nakamura, Nori

    2016-01-01

    It has been recognized that malignancies in blood cells often bear specific chromosome translocations or gene fusions. In recent years, the presence of fusion genes became to be known also among solid cancers as driver mutations. However, representative solid cancers bearing specific gene fusions are limited to cancers of thyroid, prostate, and sarcomas among which only thyroid cancer risk is known to be related to radiation exposures. On the other hand, it is extremely rare to find recurrent reciprocal translocations among common cancers such as in the lung, stomach, breast, and colon, which form a major component of radiation risks. It is therefore unlikely that radiation increases the risk of cancer by inducing specific translocations (gene fusions) but more likely through induction of mutations (including deletions). Although gene fusions could play a role in radiation carcinogenesis, it does not seem good enough to serve for a radiation fingerprint. (author)

    Two self-report experiments examined how religiosity affects attributions made for a target person's death. Online adults (Study 1, N = 427) and undergraduate students (Study 2, N = 326) read about Chris who had a heart attack, used religious or health behaviors, and lived or died. Participants made attributions to Chris and God (both studies), and reported their emotions (Study 2). Participants made more attributions to Chris when he lived than when he died, but only when he used health behaviors. The highly religious made more attributions to God, but not when Chris used religious behaviors and died (the God-serving bias); they reported the most positive emotions when Chris lived after using religious behaviors (the Hallelujah effect). Directions for future research in terms of implicit religious beliefs and normative evaluations of religion are discussed.

With this position comes a delicate power and responsibility to the moral imperative. As such, this issue is critical as a component of teacher preparation programs. Goodlad (2004 sounds the alarm that our teacher preparation programs are remiss in responding to the need for moral literacy in our schools. The following paper will introduce the philosophy of servant-leadership, a moral way of serving, as defined by Robert K.

    Because addictive behaviors typically result from violated homeostasis of the impulsive (amygdala-striatal) and inhibitory (prefrontal cortex) brain systems, this study examined whether these systems sub-serve a specific case of technology-related addiction, namely Facebook "addiction." Using a go/no-go paradigm in functional MRI settings, the study examined how these brain systems in 20 Facebook users (M age = 20.3 yr., SD = 1.3, range = 18-23) who completed a Facebook addiction questionnaire, responded to Facebook and less potent (traffic sign) stimuli. The findings indicated that at least at the examined levels of addiction-like symptoms, technology-related "addictions" share some neural features with substance and gambling addictions, but more importantly they also differ from such addictions in their brain etiology and possibly pathogenesis, as related to abnormal functioning of the inhibitory-control brain system.

    Houde, Sylvie

    Since the implementation of the latest reform in the education programs of Quebec, the adaptation of teaching has taken on an important place in the concerns of all actors in education. However, this adjustment towards the adoption of teaching practices that require more participation on the part of the pupil is not accomplished so easily, particularly in the field of science and technology (ST). In order to gain a better understanding of these processes of adaptation, it is opportune to question ourselves on the factors and dynamics of interest at stake, especially in disadvantaged environments. Such environments are faced with situations where other difficulties coexist: integration of pupils, lack of interest, problems in classroom management, multi-ethnicity, etc. As a result, such difficulties give rise to particular limitations, expressed in the form of needs, by pupils and teachers, likely to have a restrictive effect on the adaptation of teaching practices. Accordingly, our research focuses on the needs perceived by teachers in high school ST classrooms in disadvantaged school environments, since they present a privileged means to better understand the processes involved in the adaptation of practices. The adoption of an ecosystemic perspective, centered on these needs and their contribution towards the dynamics of decision-making, enabled us to better apprehend the complexity of these processes in ST classrooms. We were able to identify the needs perceived by teachers by following the methodology of conceptanalysis of needs, and by combining focus groups with the DRAP software. The results account for the large variety of needs to be considered in the equation of adaptation of teaching practices. These needs generally belong to the classroom system (microsystem). For pupils, they are mainly cognitive needs, but for teachers, they pertain to organization and structure. The influence of these needs on the adaptation processes depends on the interpretation by

    The Earth2Class (E2C) workshops, held at the Lamont-Doherty Earth Observatory (LDEO), provide an effective model for improving knowledge, teaching, and technology skills of middle and high school science educators through ongoing interactions with research scientists and educational technology. With support from an NSF GeoEd grant, E2C has developed monthly workshops, web-based resources, and summer institutes in which classroom teachers and research scientists have produced exemplar curriculum materials about a wide variety of cutting-edge geoscience investigations suitable for dissemination to teachers and students. Some of the goals of this program are focused to address questions such as: (1) What aspects of the E2C format and educational technology most effectively connect research discoveries with classroom teachers and their students? (2) What benefits result through interactions among teachers from highly diverse districts and backgrounds with research scientists, and what benefits do the scientists gain from participation? (3) How can the E2C format serve as a model for other research institution-school district partnerships as a mechanism for broader dissemination of scientific discoveries? E2C workshops have linked LDEO scientists from diverse research specialties-seismology, marine geology, paleoclimatology, ocean drilling, dendrochronology, remote sensing, impact craters, and others-with teachers from schools in the New York metropolitan area. Through the workshops, we have trained teachers to enhance content knowledge in the Earth Sciences and develop skills to incorporate new technologies. We have made a special effort to increase the teaching competency of K-12 Earth Sciences educators serving in schools with high numbers of students from underrepresented groups, thereby providing greater role models to attract students into science and math careers. E2C sponsored Earth Science Teachers Conferences, bringing together educators from New York and New

  14. Working class conservatism: a system justification perspective.

    Jost, John T

    2017-12-01

    Working class conservatism is a perennial issue in social science, but researchers have struggled to provide an adequate characterization. In social psychology, the question has too often been framed in 'either/or' terms of whether the disadvantaged are more or less likely to support the status quo than the advantaged. This is a crude rendering of the issue obscuring the fact that even if most working class voters are not conservative, millions are-and conservatives could not win elections without their support. System justification theory highlights epistemic, existential, and relational needs to reduce uncertainty, threat, and social discord that are shared by everyone-and that promote conservative attitudes. I summarize qualitative and quantitative evidence of system justification among the disadvantaged and consider prospects for more constructive political activity. Copyright © 2017 Elsevier Ltd.

    Serving the Reich tells the story of physics under Hitler. While some scientists tried to create an Aryan physics that excluded any 'Jewish ideas', many others made compromises and concessions as they continued to work under the Nazi regime. Among them were three world-renowned physicists: Max Planck, pioneer of quantum theory, regarded it as his moral duty to carry on under the regime. Peter Debye, a Dutch physicist, rose to run the Reich's most important research institute before leaving for the United States in 1940. Werner Heisenberg, discovered the Uncertainty Principle, and became the leading figure in Germany's race for the atomic bomb. After the war most scientists in Germany maintained they had been apolitical or even resisted the regime: Debye claimed that he had gone to America to escape Nazi interference in his research; Heisenberg and others argued that they had deliberately delayed production of the atomic bomb.

The Science in Schools Research Project is a DEET funded project under the Science in Schools Strategy, developed in response to recent research and policy decisions at national and state levels through which literacy, numeracy and science have been identified as key priorities for learning. This major science research project aims to identify, develop and trial best practice in Science teaching and learning. The Department will then be able to provide clear advice to Victoria's schools that can be adopted and sustained to: * enhance teaching and learning of Science * enhance student learning outcomes in Science at all year levels * increase student access to, and participation in Science learning from Prep through to Year 10, and hence in the VCE as well. The nature of the SiS program will be detailed with specific reference to the innovative programs in solar model cars, robotics and environmental science developed at Forest Hill College in response to this project.

  20. Assessing predictors of science grades and career goals in university undergraduates

    Patanella, Daniel Francis

    The utility of traditional predictors of both science grades and career goals (SAT and GPA) was compared to psychological predictors such as Piagetian stage (as measured by the Group Assessment of Logical Thinking), sex-role schema (as measured by the Bem Sex-Role Inventory, and self-schema in students enrolled in either psychology classes (n = 123) or biology classes (n = 56). While the overall predictive ability of the model was high (R = .73), the strongest predictors of grade in science class were traditional variables and not psychological ones as predicted. Prediction of career goal, while more modest (R = .19), was best served by the psychological variable of self-schema. Subsequent analyses indicated that Piagetian stage was best conceptualized as a mediating variable and that sex-role schema as measured played almost no role in either grade or career goal, as well as verifying the internal validity of the self-schema measure used. Biology students were more likely to possess a science self-schema than psychology students (chi2 (1,179) = 7.34, p < .01) and outperformed psychology students on the Piagetian questions (t(177) = 3.01, p < .01). Response latency was recorded for all participants' answer to the Piagetian questions; contrary to prediction however, the inclusion of response latency did not add to the predictive ability of the Piagetian measure used.

    Hoisch, T. D.; Bowie, J. I.

    2009-12-01

    In order to guide the formulation of strategies for recruiting undergraduates taking introductory geology courses into the geology program at Northern Arizona University, we surveyed 783 students in introductory geology classes and 23 geology majors in their junior and senior years. Our introductory courses (GLG100, Introduction to Geology; GLG101, Physical Geology; and GLG112, Geologic Disasters) typically enroll ~600 students each semester. The majority of students in these classes are non-majors who take them in order to satisfy a university general education requirement (called “Liberal Studies requirements” at NAU). A large proportion of these students are freshmen (51%) and sophomores (30%), and many have not yet decided on a major or are uncertain about the major they have chosen. Our analysis shows that ~7% of students in the introductory classes are possible candidates for recruitment. Although a small percentage, it represents a large number of individuals, in fact more than could be accommodated were they all to decide to major in geology. Influential factors that weigh in favor of majoring in geology include good employability, good salary potential, and opportunities for working outdoors, field work, observing nature, travel, and environmentally friendly employment. In addition, students view a career as a geologist as potentially the most fulfilling of the different science occupations (biologist, chemist, geologist, environmental scientist, physicist) and among the more environmentally friendly. However, students perceive geology to be the least difficult of the sciences, and geology occupations to be low-paying and low in prestige relative to the other sciences. These negative perceptions could be countered by providing data to introductory students showing the starting salaries of geologists in comparison to other science occupations, and by communicating the rigorous nature of the more advanced classes in the geology degree program.

    Economy class syndrome is venous thromboembolism following air travel. This syndrome was firstly reported in 1946, and many cases have been reported since 1990s. Low air pressure and low humidity in the aircraft cabin may contribute to the mechanism of this syndrome. Risk factors for venous thrombosis in the plane were old age, small height, obesity, hormonal therapy, malignancy, smoking, pregnancy or recent parturition, recent trauma or operation, chronic disease and history of venous thrombosis. In Japan, the feminine gender is also risk factor though reason was not well known. For prophylaxis, adequate fluid intake and leg exercise are recommended to all passengers. For passengers with high risk, prophylactic measures such as compression stockings, aspirin or low molecular weight heparin should be considered.

  6. Making the middle classes on shifting ground? Residential status, performativity and middle-class subjectivities in contemporary London.

    Benson, Michaela; Jackson, Emma

    This paper argues that shifts in access to housing - both in relation to rental and ownership - disrupt middle-class reproduction in ways that fundamentally influence class formation. While property ownership has had a long association with middle-class identities, status and distinction, an increasingly competitive rental market alongside inflated property prices has impacted on expectations and anxieties over housing futures. In this paper, we consider two key questions: (1) What happens to middle-class identities under the conditions of this wider structural change? (2) How do the middle classes variously manoeuvre within this? Drawing on empirical research conducted in London, we demonstrate that becoming an owner-occupier may be fractured along lines of class but also along the axes of age, wealth and timing, particularly as this relates to the housing market. It builds on understandings of residential status and place as central to the formation of class, orienting this around the recognition of both people and place as mutable, emphasizing that changing economic and social processes generate new class positionalities and strategies for class reproduction. We argue that these processes are writ large in practices of belonging and claims to place, with wider repercussions within the urban landscape. © London School of Economics and Political Science 2017.

    2013-06-01

    Elementary teachers face increasing demands to engage children in authentic science process and argument while simultaneously preparing them with knowledge of science facts, vocabulary, and concepts. This reform is particularly challenging due to concerns that elementary teachers lack adequate science background to teach science accurately. This study examined 81 in-classroom inquiry science lessons for preservice education majors and their cooperating teachers to determine the accuracy of the science content delivered in elementary classrooms. Our results showed that 74 % of experienced teachers and 50 % of student teachers presented science lessons with greater than 90 % accuracy. Eleven of the 81 lessons (9 preservice, 2 cooperating teachers) failed to deliver accurate science content to the class. Science content accuracy was highly correlated with the use of kit-based resources supported with professional development, a preference for teaching science, and grade level. There was no correlation between the accuracy of science content and some common measures of teacher content knowledge (i.e., number of college science courses, science grades, or scores on a general science content test). Our study concluded that when provided with high quality curricular materials and targeted professional development, elementary teachers learn needed science content and present it accurately to their students.

  8. Network class superposition analyses.

    Directory of Open Access Journals (Sweden)

    Carl A B Pearson

    Full Text Available Networks are often used to understand a whole system by modeling the interactions among its pieces. Examples include biomolecules in a cell interacting to provide some primary function, or species in an environment forming a stable community. However, these interactions are often unknown; instead, the pieces' dynamic states are known, and network structure must be inferred. Because observed function may be explained by many different networks (e.g., ≈ 10(30 for the yeast cell cycle process, considering dynamics beyond this primary function means picking a single network or suitable sample: measuring over all networks exhibiting the primary function is computationally infeasible. We circumvent that obstacle by calculating the network class ensemble. We represent the ensemble by a stochastic matrix T, which is a transition-by-transition superposition of the system dynamics for each member of the class. We present concrete results for T derived from boolean time series dynamics on networks obeying the Strong Inhibition rule, by applying T to several traditional questions about network dynamics. We show that the distribution of the number of point attractors can be accurately estimated with T. We show how to generate Derrida plots based on T. We show that T-based Shannon entropy outperforms other methods at selecting experiments to further narrow the network structure. We also outline an experimental test of predictions based on T. We motivate all of these results in terms of a popular molecular biology boolean network model for the yeast cell cycle, but the methods and analyses we introduce are general. We conclude with open questions for T, for example, application to other models, computational considerations when scaling up to larger systems, and other potential analyses.

    Discovered that some of blades Damascus steel has an unusual nature of origin of the excess cementite, which different from the redundant phases of secondary cementite, cementite of ledeburite and primary cementite in iron-carbon alloys. It is revealed that the morphological features of separate particles of cementite in Damascus steels lies in the abnormal size of excess carbides having the shape of irregular prisms. Considered three hypotheses for the formation of excess cementite in the form of faceted prismatic of excess carbides. The first hypothesis is based on thermal fission of cementite of a few isolated grains. The second hypothesis is based on the process of fragmentation cementite during deformation to the separate the pieces. The third hypothesis is based on the transformation of metastable cementite in the stable of angular eutectic carbide. It is shown that the angular carbides are formed within the original metastable colony ledeburite, so they are called “eutectic carbide”. It is established that high-purity white cast iron is converted into of Damascus steel during isothermal soaking at the annealing. It was revealed that some of blades Damascus steel ledeburite class do not contain in its microstructure of crushed ledeburite. It is shown that the pattern of carbide heterogeneity of Damascus steel consists entirely of angular eutectic carbides. Believe that Damascus steel refers to non-heat-resistant steel of ledeburite class, which have similar structural characteristics with semi-heat-resistant die steel or heat-resistant high speed steel, differing from them only in the nature of excess carbide phase.

  10. Understanding Class in Contemporary Societies

    Harrits, Gitte Sommer

    2007-01-01

    In this paper, I argue that claims about the death of class and the coming of the classless society are premature. Such claims are seldom genuinely empirical, and the theoretical argument often refers to a simple and therefore easily dismissible concept of class. By rejecting the concept of class...... altogether, sociological theory runs the risk of loosing the capacity for analysing stratification and vertical differentiation of power and freedom, which in late modernity seem to be a of continuing importance. Hence, I argue that although class analysis faces a number of serious challenges, it is possible...... to reinvent class analysis. The sociology of Pierre Bourdieu in many ways introduces an appropriate paradigm, and the paper therefore critically discusses Bourdieu's concept of class. Since the "Bourdieuan" class concept is primarily epistemological, i.e. a research strategy more than a theory, empirical...

    The Energy Sciences Network (ESnet) is the primary provider of network connectivity for the US Department of Energy Office of Science, the single largest supporter of basic research in the physical sciences in the United States. In support of the Office of Science programs, ESnet regularly updates and refreshes its understanding of the networking requirements of the instruments, facilities, scientists, and science programs that it serves. This focus has helped ESnet to be a highly successful enabler of scientific discovery for over 20 years. In April 2010 ESnet and the Office of Biological and Environmental Research, of the DOE Office of Science, organized a workshop to characterize the networking requirements of the science programs funded by BER. The requirements identified at the workshop are summarized and described in more detail in the case studies and the Findings section. A number of common themes emerged from the case studies and workshop discussions. One is that BER science, like many other disciplines, is becoming more and more distributed and collaborative in nature. Another common theme is that data set sizes are exploding. Climate Science in particular is on the verge of needing to manage exabytes of data, and Genomics is on the verge of a huge paradigm shift in the number of sites with sequencers and the amount of sequencer data being generated.

  13. Enacting science

    Science.gov (United States)

    MacDonald, Anthony Leo

    My study examines the development of forms of knowing that arise when students engage in open-ended explorations involving self-directed design and building involving simple materials. It is grounded in an enactivist theoretical perspective on cognition which holds that the creation of action-thought processes for engaging the world is interwoven with the meanings that are constructed for these experiences. A dynamic conception of persons-acting-in-a-setting is fundamental to an enactivist view of cognition. How is understanding enacted in building activity? How does the shape of a problem emerge? How do students enact meaning and understanding when they experience a high degree of physical engagement in building things? What are some characteristics of an enactive learning/teaching environment? My research settings comprise a range of individual, group and classroom engagements of varying lengths over a three and one-half year period. The first research episode involved two grade eight students in an investigation of Paper Towels. The second four month engagement was in a grade nine science class that culminated in the building of a Solar House. The third grade ten episode involved a one month project to build a Mousetrap Powered Car. A fourth Invent a Machine project was conducted in two grade eight science classes taught by the teacher who participated in the Solar House project. Two students were present in three of the four projects. I interviewed one of these students upon completion of his high school physics courses. I found that building is a form of thinking which develops competency in managing complex practical tasks. A triadic relationship of exploration, planning and acting is present. Practical and procedural understandings emerge as students enter and re-enter self-directed problem settings. Thinking patterns depend on the kinds of materials chosen, the ways they are used, and on how students contextualize the problem. Classroom assessment

    Full Text Available This paper presents a simplified approach for predicting the allowable load repetitions of New Large Aircraft (NLA loading for airfield runways based on Non-Destructive Test (NDT data. Full-scale traffic test results from the Federal Aviation Administration’s National Airport Pavement Test Facility (NAPTF were used to develop the NDT-based evaluation methodology. Four flexible test pavement sections with variable (unbound layer thicknesses were trafficked using six-wheel and four-wheel NLA test gears until the test pavements were deemed failed. Non-destructive tests using a Heavy Weight Deflectometer (HWD were conducted prior to the initiation of traffic testing to measure the pavement surface deflections. In the past, pavement surface deflections have been successfully used as an indicator of airport pavement life. In this study, the HWD surface deflections and the derived Deflection Basin Parameters (DBPs were related to functional performance of NAPTF flexible pavements through simple regression analysis. The results demonstrated the usefulness of NDT data for predicting the performance of airport flexible pavements serving the next generation of aircrafts.

  15. Are men well served by family planning programs?

    2017-01-23

    Although the range of contraceptives includes methods for men, namely condoms, vasectomy and withdrawal that men use directly, and the Standard Days Method (SDM) that requires their participation, family planning programming has primarily focused on women. What is known about reaching men as contraceptive users? This paper draws from a review of 47 interventions that reached men and proposes 10 key considerations for strengthening programming for men as contraceptive users. A review of programming shows that men and boys are not particularly well served by programs. Most programs operate from the perspective that women are contraceptive users and that men should support their partners, with insufficient attention to reaching men as contraceptive users in their own right. The notion that family planning is women's business only is outdated. There is sufficient evidence demonstrating men's desire for information and services, as well as men's positive response to existing programming to warrant further programming for men as FP users. The key considerations focus on getting information and services where men and boys need it; addressing gender norms that affect men's attitudes and use while respecting women's autonomy; reaching adolescent boys; including men as users in policies and guidelines; scaling up successful programming; filling gaps with implementation research and monitoring & evaluation; and creating more contraceptive options for men.

    Differences in how services are organized and delivered can contribute significantly to variation in outcomes experienced by children and families. However, few comparative studies identify the strengths and limitations of alternative delivery system configurations. The current study provides the first empirical typology of private agencies involved with the formal child welfare system. Data collected in 2011 from a national sample of private agencies were used to classify agencies into five distinct groups based on internal management capacity, service diversification, integration, and policy advocacy. Findings reveal considerable heterogeneity in the population of private child and family serving agencies. Cross-group comparisons suggest that differences in agencies' strategic and structural characteristics correlated with agency directors' perceptions of different pressures in their external environment. Future research can use this typology to better understand local service systems and the extent to which different agency strategies affect performance and other outcomes. Such information has implications for public agency contracting decisions and could inform system-level assessment and planning of services for children and families.

    2002-10-01

    To keep pace with emerging competition in the North-American energy industry, Hydro-Quebec restructured its activities into four separate divisions. Hydro-Quebec TransEnergie, established in 1977, is the division responsible for energy transmission, whereas Hydro-Quebec Distribution, established in 2001, looks after distribution services. They and the two sister divisions (Hydro-Quebec Production and Hydro-Quebec Equipement) serve 2.8 million residential, institutional and industrial customers, scattered across 587,500 square kilometres. The restructuring provided the opportunity to adapt to new market realities. Automated Meter Reading (AMR) ties in directly with the new business-oriented approach the utility has adopted in the late 1990s. In addition to solving meter accessibility problems and reducing operating costs, automated meter reading provides customers with the opportunity to benefit from new services designed to meet specific needs. To date new services made possible by automated meter reading include customized reading date selection, aggregated billing, consumption tracking and load management. AMR not only translates into greater flexibility and added value for the customer. It also provides greater reliability, accuracy and better system management. In short, AMR paves the way for the optimization of the power supply, new consumption management capabilities, rate options, real-time billing and enhanced fraud detection.

    Over recent decades, epidemiology has made significant contributions to our understanding of dementia, translating scientific discoveries into population health. Here, we propose reframing dementia epidemiology as "population neuroscience," blending techniques and models from contemporary neuroscience with those of epidemiology and biostatistics. On the basis of emerging evidence and newer paradigms and methods, population neuroscience will minimize the bias typical of traditional clinical research, identify the relatively homogenous subgroups that comprise the general population, and investigate broader and denser phenotypes of dementia and cognitive impairment. Long-term follow-up of sufficiently large study cohorts will allow the identification of cohort effects and critical windows of exposure. Molecular epidemiology and omics will allow us to unravel the key distinctions within and among subgroups and better understand individuals' risk profiles. Interventional epidemiology will allow us to identify the different subgroups that respond to different treatment/prevention strategies. These strategies will inform precision medicine. In addition, insights into interactions between disease biology, personal and environmental factors, and social determinants of health will allow us to measure and track disease in communities and improve population health. By placing neuroscience within a real-world context, population neuroscience can fulfill its potential to serve both precision medicine and population health.

    2014-09-01

    Full Text Available This article presents a qualitative study conducted at a Historically Hispanic Serving Institution (HHSI to further the understanding of its internationalization decision-making process. The study uses the Internationalization Cube model to review the institution’s internal processes and policies toward internationalization and assess how its international activities align with its internationalization efforts. The Internationalization Cube, an eight-cell model, permits the positioning of Institutions of Higher Education (IHEs based on the analysis of its three dimensions and respective subcategories: policy, support, and implementation. The International Dimension Index (IDI and the Item Relevancy Index (IRI were also used to determine the level of alignment between the HHSI position on the Internationalization Cube and its international activities. The study finds that the HHSI is on Position 6 on the Internationalization Cube (priority policy, one-sided support, and systematic/structure implementation, and exhibits all the international activities considered indicators of internationalization but attention is needed to foreign language, international students, study abroad, faculty movement and involvement in international projects. The study concludes that an association exists between the institution’s position on the Internationalization Cube and its international activities, and adjustments in the institution’s policy, support, and implementation dimensions will be required to advance its position on the Internationalization Cube making its internationalization process more sustainable. This study makes a contribution to addressing the need to assess an IHE by presenting a holistic organizational framework instead of a fragmented international activities organizational analysis.

    2011-12-01

    With the recent announcement of Québec's provincial government's Plan Nord, Nunavik will see a 500 new houses sweep onto it's territory over the next 5 years. The local Inuit communities are confronted with the pressuring need to find suitable land to safely accommodate the new infrastructures in the long term. Additional to human and environmental constraints are those related to warming permafrost. Intensive studies on four Nunavik communities (Inukjuak, Puvirnituq, Akulivik, Kangirsuk) have allowed us to extensively consult local and regional authorities on their planning and management considerations. Recent and archived drilling data have been used to corroborate air photo interpretation, surficial geology and permafrost mapping. All collected information are integrated into aggregated maps that will eventually serve as community master plans. General recommendations on how to best manage and plan for community expansions on warming permafrost are made. Appropriate engineering techniques assuring long-term stable foundations are outlined and additionally mapped, taking into consideration the variable terrain conditions and simulated changes in permafrost temperature and active layer thickness according to climate change scenarios. The final purpose of our results is for them to support local and regional governments in their community planning process towards the best possible climate change adaptation strategies.
