The 20th mission of the National Aeronautics and Space Administration (NASA) Extreme Environment Mission Operations (NEEMO) was a highly integrated evaluation of operational protocols and tools designed to enable future exploration beyond low-Earth orbit. NEEMO 20 was conducted from the Aquarius habitat off the coast of Key Largo, FL in July 2015. The habitat and its surroundings provide a convincing analog for space exploration. A crew of six (comprised of astronauts, engineers, and habitat technicians) lived and worked in and around the unique underwater laboratory over a mission duration of 14-days. Incorporated into NEEMO 20 was a diverse Science Team (ST) comprised of geoscientists from the Astromaterials Research and Exploration Science (ARES/XI) Division from the Johnson Space Center (JSC), as well as marine scientists from the Department of Biological Sciences at Florida International University (FIU). This team trained the crew on the science to be conducted, defined sampling techniques and operational procedures, and planned and coordinated the science focused Extra Vehicular Activities (EVAs). The primary science objectives of NEEMO 20 was to study planetary sampling techniques and tools in partial gravity environments under realistic mission communication time delays and operational pressures. To facilitate these objectives two types of science sites were employed 1) geoscience sites with available rocks and regolith for testing sampling procedures and tools and, 2) marine science sites dedicated to specific research focused on assessing the photosynthetic capability of corals and their genetic connectivity between deep and shallow reefs. These marine sites and associated research objectives included deployment of handheld instrumentation, context descriptions, imaging, and sampling; thus acted as a suitable proxy for planetary surface exploration activities. This abstract briefly summarizes the scientific training, scientific operations, and tool development conducted during NEEMO 20 with an emphasis on the primary lessons learned.

Using Primary Literature to Teach Science Literacy to Introductory Biology Students

PubMed Central

Krontiris-Litowitz, Johanna

2013-01-01

Undergraduate students struggle to read the scientific literature and educators have suggested that this may reflect deficiencies in their science literacy skills. In this two-year study we develop and test a strategy for using the scientific literature to teach science literacy skills to novice life science majors. The first year of the project served as a preliminary investigation in which we evaluated student science literacy skills, created a set of science literacy learning objectives aligned with Bloom’s taxonomy, and developed a set of homework assignments that used peer-reviewed articles to teach science literacy. In the second year of the project the effectiveness of the assignments and the learning objectives were evaluated. Summative student learning was evaluated in the second year on a final exam. The mean score was 83.5% (±20.3%) and there were significant learning gains (p < 0.05) in seven of nine of science literacy skills. Project data indicated that even though students achieved course-targeted lower-order science literacy objectives, many were deficient in higher-order literacy skills. Results of this project suggest that building scientific literacy is a continuing process which begins in first-year science courses with a set of fundamental skills that can serve the progressive development of literacy skills throughout the undergraduate curriculum.

NASA's Wide-field Infrared Survey Explorer (WISE) has achieved its fundamental goal by delivering its all-sky survey at 3.4, 4.6, 12 and 22 (micron) (W1, W2, W3, and W4), reaching sensitivities hundreds of times deeper than IRAS. One of the two primary science objectives for WISE is to identify the most luminous galaxies in the Universe (Ultra-Luminous IR Galaxies, or ULIRGs). We have used WISE photometry to select an all- sky sample of objects which are extremely luminous, and for which Herschel far-IR follow-up observations are underway. The objects are prominent in W3 and W4, but faint or undetected in W1 and W2. Available spectroscopy and far IR photometry for these objects show they typically have redshifts z > 2 and luminosities over 10^13 L_odot, with about 10% exceeding 10^14 L_odot and rivaling the brightest known QSOs. Their dust is more than twice as hot as other IR luminous objects: they are hot dust obscured galaxies or ``hot DOGs," and may represent a new phase in galaxy evolution. We request NOAO time to obtain redshifts and optical and near IR photometry for the all-sky sample of the brightest hot DOGs, all of which are in our Herschel program. With existing and allocated observations, this request should complete the acquisition of these crucial data for this primary WISE science objective.

The objects are prominent in W3 and W4, but faint or undetected in W1 and W2. The spectroscopy and far IR photometry for these objects show they typically have redshifts z > 2 and luminosities over 10^13 L_⊙, with about 5 - 10% exceeding 10^14 L_⊙ and rivaling the brightest known QSOs. Their dust is more than twice as hot as other IR luminous objects: they are hot dust obscured galaxies or ``hot DOGs," and may represent a new phase in galaxy evolution. Because our 2012B allocation had mixed weather, we request 2013B NOAO time to complete the collection of redshifts and optical and near IR photometry for this all-sky sample of the brightest hot DOGs. With existing and allocated observations, this request should complete the acquisition of these crucial data for this primary WISE science objective.

Fighting for life: Religion and science in the work of fish and wildlife biologists

NASA Astrophysics Data System (ADS)

Geffen, Joel Phillip

Philosophers, historians, and sociologists of science have argued that it is impossible to separate fact from value. Even so, Americans generally demand that scientists be "objective." No bias is permitted in their work. Religious motivations in particular are widely considered anathema within the halls of science. My dissertation addresses both theoretical and practical aspects concerning objectivity in science through an examination of fish and wildlife biologists. I hypothesized that they use the language of objective science as a tool to convince others to protect habitats and species. Further, I claimed that this "rhetoric of science" is employed either consciously or unconsciously on behalf of personal values, and that religious and/or spiritual values figure significantly among these. Regarding the issue's practical applications, I argued in support of Susan Longino's assertion that while subjective influences exist in science, they do not necessarily indicate that objectivity has been sacrificed. My primary methodology is ethnographic. Thirty-five biologists working in the Pacific Northwest were interviewed during the course of summer 2001. Participant ages ranged from 23 to 78. Both genders were represented, as were various ethnic and cultural backgrounds, including Native American. I used a questionnaire to guide respondents through a consistent set of open-ended queries. I organized their answers under four categories: the true, the good, the beautiful, and the holy. The first three were borrowed from the theoretical writings of philosopher Immanuel Kant. The last came from Rudolf Otto's theological work. These categories provided an excellent analytical framework. I found that the great majority of fish and wildlife biologists strive for objectivity. However, they are also informed by powerful contextual values. These are derived from environmental ethics, aesthetic preferences pertaining to ecosystem appearance and function, and visceral experiences of connection with nature. These were blended into their practice of science to varying degrees. My hypothesis was affirmed. Science is not value-free, and nor can it be. Yet, contextual values do not necessarily undermine scientific objectivity.

Major hardware tasks include developing NASA s Evolutionary Xenon Thruster (NEXT), developing a long-life High Voltage Hall Accelerator (HIVHAC), developing an advanced feed system, and developing cross-platform components. The objective of the NEXT task is to advance next generation ion propulsion technology readiness. The baseline NEXT system consists of a high-performance, 7-kW ion thruster; a high-efficiency, 7-kW power processor unit (PPU); a highly flexible advanced xenon propellant management system (PMS); a lightweight engine gimbal; and key elements of a digital control interface unit (DCIU) including software algorithms. This design approach was selected to provide future NASA science missions with the greatest value in mission performance benefit at a low total development cost. The objective of the HIVHAC task is to advance the Hall thruster technology readiness for science mission applications. The task seeks to increase specific impulse, throttle-ability and lifetime to make Hall propulsion systems applicable to deep space science missions. The primary application focus for the resulting Hall propulsion system would be cost-capped missions, such as competitively selected, Discovery-class missions. The objective of the advanced xenon feed system task is to demonstrate novel manufacturing techniques that will significantly reduce mass, volume, and footprint size of xenon feed systems over conventional feed systems. This task has focused on the development of a flow control module, which consists of a three-channel flow system based on a piezo-electrically actuated valve concept, as well as a pressure control module, which will regulate pressure from the propellant tank. Cross-platform component standardization and simplification are being investigated through the Standard Architecture task to reduce first user costs for implementing electric propulsion systems. Progress on current hardware development, recent test activities and future plans are discussed.

2017-10-01

Studies have shown that there is a need for pedagogical content knowledge among science teachers. This study investigates two primary teachers and their objectives in choosing inquiry- and context-based instructional strategies as well as the relation between the choice of instructional strategies and the teachers' knowledge about of students' understanding and intended learning outcomes. Content representations created by the teachers and students' experiences of the enacted teaching served as foundations for the teachers' reflections during interviews. Data from the interviews were analyzed in terms of the intended, enacted, and experienced purposes of the teaching and, finally, as the relation between intended, enacted, and experienced purposes. Students' experiences of the teaching were captured through a questionnaire, which was analyzed inductively, using content analysis. The results show that the teachers' intended teaching objectives were that students would learn about water. During the enacted teaching, it seemed as if the inquiry process was in focus and this was also how many of the students experienced the objectives of the activities. There was a gap between the intended and experienced objectives. Hardly any relation was found between the teachers' choice of instructional strategies and their knowledge about students' understanding, with the exception that the teacher who also added drama wanted to support her students' understanding of the states of water.

This study explored the different kinds of unintended learning in primary school practical science lessons. In this study, unintended learning has been defined as student learning that was found to occur that was not included in the teachers learning objectives for that specific lesson. A total of 22 lessons, taught by five teachers in Korean primary schools with 10- to 12-year-old students, were audio-and video recorded. Pre-lesson interviews with the teachers were conducted to ascertain their intended learning objectives. Students were asked to write short memos after the lesson about what they learnt. Post-lesson interviews with students and teachers were undertaken. What emerged was that there were three types of knowledge that students learnt unintentionally: factual knowledge gained by phenomenon-based reasoning, conceptual knowledge gained by relation- or model-based reasoning, and procedural knowledge acquired by practice. Most unintended learning found in this study fell into the factual knowledge and only a few cases of conceptual knowledge were found. Cases of both explicit procedural knowledge and implicit procedural knowledge were found. This study is significant in that it suggests how unintended learning in practical work can be facilitated as an educative opportunity for meaningful learning by exploring what and how students learnt.

1988-01-01

The primary objective of the SIR-B experiment was to acquire multiple-incidence-angle radar imagery of a variety of Earth's surfaces to better understand the effects of imaging geometry on radar backscatter. A complementary objective was to map extensive regions of particular interest. Under these broad objectives, many specific scientific experiments were defined by the 43 SIR-B Science Team members, including studies in the area of geology, vegetation, radar penetration, oceanography, image analysis, and calibration technique development. Approximately 20 percent of the planned digital data were collected, meeting 40 percent of the scientific objectives. This report is an overview of the SIR-B experiment and includes the science investigations, hardware design, mission scenario, mission operations, events of the actual missions, astronaut participation, data products (including auxiliary data), calibrations, and a summary of the actual coverage. Also included are several image samples.

A study of the effectiveness of the primary education improvement program (science) in selected schools of Northern Nigeria

NASA Astrophysics Data System (ADS)

Brown, Desmond P.; Reed, Jack A.

The Primary Education Improvement Program (Science) developed in Nigeria from 1970-1980 adopted a process approach to the teaching of science for children in Classes One and Two of primary school. In that insufficient formative data were available a study was organized to evaluate the attainment of the program's major objectives in terms of the children's ability to practice process skills. The study also attempted to measure children's interest, active participation and understanding of the lessons, as well as the availability of materials and ease of preparing and teaching the lessons for the teachers. Data were collected by means of teacher opinionnaires and a children's test to measure the attainment of process skills. The teachers who completed the opinionnaires rated the program as successful in terms of all the measured criteria. Children in the experimental and control groups were tested and their performances were compared. The results indicated that there were some significant differences in total test scores in favor of the experimental group after one year of primary school but none after two years. The program, though highly rated by teachers, did not produce the intended changes in children's behavior.

Technical Report Series on Global Modeling and Data Assimilation. Volume 42; Soil Moisture Active Passive (SMAP) Project Calibration and Validation for the L4_C Beta-Release Data Product

2015-01-01

During the post-launch Cal/Val Phase of SMAP there are two objectives for each science product team: 1) calibrate, verify, and improve the performance of the science algorithms, and 2) validate accuracies of the science data products as specified in the L1 science requirements according to the Cal/Val timeline. This report provides analysis and assessment of the SMAP Level 4 Carbon (L4_C) product specifically for the beta release. The beta-release version of the SMAP L4_C algorithms utilizes a terrestrial carbon flux model informed by SMAP soil moisture inputs along with optical remote sensing (e.g. MODIS) vegetation indices and other ancillary biophysical data to estimate global daily NEE and component carbon fluxes, particularly vegetation gross primary production (GPP) and ecosystem respiration (Reco). Other L4_C product elements include surface (<10 cm depth) soil organic carbon (SOC) stocks and associated environmental constraints to these processes, including soil moisture and landscape FT controls on GPP and Reco (Kimball et al. 2012). The L4_C product encapsulates SMAP carbon cycle science objectives by: 1) providing a direct link between terrestrial carbon fluxes and underlying freeze/thaw and soil moisture constraints to these processes, 2) documenting primary connections between terrestrial water, energy and carbon cycles, and 3) improving understanding of terrestrial carbon sink activity in northern ecosystems.

The dark side of risk and crisis communication: legal conflicts and responsibility allocation

NASA Astrophysics Data System (ADS)

Scolobig, A.

2015-04-01

Inadequate, misinterpreted or missing risk and crisis communication may be a reason for practitioners, and sometimes even science advisors, to become subjects of criminal charges. This work discusses the legal consequences of communication. After presenting some cases, the discussion focuses on three critical issues: the development of effective communication protocols; the role, tasks and responsibilities of science advisors; and the collateral effects of practitioners' defensive behaviours. For example, if the avoidance of personal liability becomes a primary objective for practitioners, it may clash with other objectives, such as the protection of vulnerable communities or the transparency of decision-making. The conclusion presents some ideas for future research on the legal aspects of risk communication.

Critical Zone Science as a Multidisciplinary Framework for Teaching Earth Science and Sustainability

Wymore, A.; White, T. S.; Dere, A. L. D.; Hoffman, A.; Washburne, J. C.; Conklin, M. H.

2016-12-01

The Earth's Critical Zone (CZ) is the terrestrial portion of the continents ranging from the top of the vegetative canopy down through soil and bedrock to the lowest extent of freely circulating groundwater. The primary objective of CZ science is to characterize and understand how the reciprocal interactions among rock, soil, water, air and terrestrial organisms influence the Earth as a habitable environment. Thus it is a highly multidisciplinary science that incorporates the biological, hydrological, geological and atmospheric sciences and provides a holistic approach to teaching Earth system science. Here we share highlights from a full-semester university curriculum that introduces upper-division Environmental Science, Geology, Hydrology and Earth Science students to CZ science. We emphasize how a CZ framework is appropriate to teach concepts across the scientific disciplines, concepts of sustainability, and how CZ science serves as a useful approach to solving humanities' grand challenges.

If an antelope is a document, then a rock is data: preserving earth science samples for the future

NASA Astrophysics Data System (ADS)

Ramdeen, S.

2015-12-01

As discussed in seminal works by Briet (1951) and Buckland (1998), physical objects can be considered documents when given specific context. In the case of an antelope, in the wild it's an animal, in a zoo it's a document. It is the primary source of information, specifically when it is made an object of study. When discussing earth science data, we may think about numbers in a spreadsheet or verbal descriptions of a rock. But what about physical materials such as cores, cuttings, fossils, and other tangible objects? The most recent version of the American Geophysical Union's data position statement states data preservation and management policies should apply to both "digital data and physical objects"[1]. If an antelope is a document, than isn't a rock a form of data? Like books in a library or items in a museum, these objects require surrogates (digital or analog) that allow researchers to access and retrieve them. Once these scientific objects are acquired, researchers can process the information they contain. Unlike books, and some museum materials, most earth science objects cannot yet be completely replaced by digital surrogates. A fossil may be scanned, but the original is needed for chemical testing and ultimately for 'not yet developed' processes of scientific analysis. These objects along with their metadata or other documentation become scientific data when they are used in research. Without documentation of key information (i.e. the location where it was collected) these objects may lose their scientific value. This creates a complex situation where we must preserve the object, its metadata, and the connection between them. These factors are important as we consider the future of earth science data, our definitions of what constitutes scientific data, as well as our data preservation and management practices. This talk will discuss current initiatives within the earth science communities (EarthCube's EC3 and iSamples; USGS's data preservation program; etc.) and within the communities of information science. As practitioners, these librarians, information scientists, and archivists work on similar issues and can offer practices and theories that might help us 'future proof' physical earth science records.

Implementation Options For the Solar System Exploration Survey's "Jupiter Polar Orbiter with Probes" Mission

NASA Astrophysics Data System (ADS)

Spilker, T. R.

2002-09-01

In July of this year the National Academy of Science released a draft of its report, "New Frontiers in the Solar System: An Integrated Exploration Strategy," briefly describing the current state of solar system planetary science and the most important science objectives for the next decade (2003-2013). It includes a prioritized list of five mission concepts that might be flown as part of NASA's fledgling New Frontiers Program; each "concept" is more a list of science or measurement objectives than a full mission concept, since it does not specify implementation details in most cases. Number three on that list is the "Jupiter Polar Orbiter with Probes" ("JPOP") mission. This mission concept combines the strengths of previously described or proposed Jupiter missions into a single mission, and gains from the synergies of some of the newly-combined investigations. The primary science objectives are: 1. Determine if Jupiter has a central core 2. Determine the deep abundance of water (and other volatiles) 3. Measure Jupiter's deep winds 4. Determine the structure of Jupiter's dynamo magnetic field 5. Sample in situ Jupiter's polar magnetosphere This paper examines some of the implementation options for a JPOP mission, and gives relative advantages and disadvantages. Given the New Frontier Program's maximum cost to NASA of \\650M, plus an approx. \\120M cap on international contributions, implementing the full range of JPOP science objectives in a single New Frontiers mission may be challenging. This work was performed at the Jet Propulsion Laboratory / California Institute of Technology, under contract with the National Aeronautics and Space Administration.

The Factors and Features of Museum Fatigue in Science Centres Felt by Korean Students

NASA Astrophysics Data System (ADS)

Kim, Minchul; Dillon, Justin; Song, Jinwoong

2018-03-01

One of the objectives of science education in science centres has been the enhancement of interest in science. However, museum fatigue has a negative impact on interest. Museum fatigue has been described as physical tiredness or a decrease in visitors' interest in a museum. The learning experience of students in science centres is also influenced by museum fatigue. The purpose of this study is to identify the phenomena of museum fatigue in science centres and to identity how it is manifested. First, we identified the factors causing museum fatigue in science centres using the data from an open-ended questionnaire which was given to 597 primary, middle and high school students in South Korea. From the responses to the questionnaire, 50 factors causing museum fatigue in science centres were identified. A second Likert-type questionnaire with the 50 factors of museum fatigue in science centres was administered to 610 primary, middle and high school students in South Korea. Using reliability and factor analyses, we developed a framework of the factors causing museum fatigue in science centres, which consists of three contexts, 12 categories and 50 factors. Secondly, through statistical analyses including T test and ANOVA analysis, the features of students' museum fatigue in science centres were analysed and compared regarding student gender, school level, interest in science, grade of school science, the number of visits, and type of visit. The results, which were found to be statistically significant, are reported and discussed. The findings of this study are intended to serve for a deeper understanding and practical improvement of science learning in science centres.

The primary objective of the Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) mission is to return a pristine sample of carbonaceous material from primitive asteroid (101955) Bennu. Understanding the geospatial context of Bennu is critical to choosing a sample-site and also linking the nature of the sample to the global properties of Bennu and the broader asteroid population. We established a planetary spatial data infrastructure (PSDI) support the primary objective of OSIRIS-REx. OSIRIS-REx is unique among planetary missions in that all remote sensing is performed to support the sample return objective. Prior to sampling, OSIRIS-REx will survey Bennu for nearly two years to select and document the most valuable primary and backup sample sites. During this period, the mission will combine coordinated observations from five science instruments into four thematic maps: deliverability, safety, sampleability, and scientific value. The deliverability map assesses the probability that the flight dynamics team can deliver the spacecraft to the desired location. The safety map indicates the probability that physical hazards are present at the sample-site. The sampleability map quantifies the probability that a sample can be successfully collected from the surface. Finally, the scientific value map shows the probability that the collected sample contains organics and volatiles and also places the sample site in a definitive geological context relative to Bennu's history. The OSIRIS-REx Science Processing and Operations Center (SPOC) serves as the operational PSDI for the mission. The SPOC is tasked with intake of all data from the spacecraft and other ground sources and assimilating these data into a single comprehensive system for processing and presentation. The SPOC centralizes all geographic data of Bennu in a relational database and ensures that standardization and provenance are maintained throughout proximity operations.The SPOC is a live system that handles inputs from spacecraft and science instrument telemetry, and science data producers. It includes multiple levels of validation, both automated and manual to process all data in a robust and reliable manner and eventually deliver it to the NASA Planetary Data System for archive.

Bio-objects and the media: the role of communication in bio-objectification processes.

PubMed

Maeseele, Pieter; Allgaier, Joachim; Martinelli, Lucia

2013-06-01

The representation of biological innovations in and through communication and media practices is vital for understanding the nature of "bio-objects" and the process we call "bio-objectification." This paper discusses two ideal-typical analytical approaches based on different underlying communication models, ie, the traditional (science- and media-centered) and media sociological (a multi-layered process involving various social actors in defining the meanings of scientific and technological developments) approach. In this analysis, the latter is not only found to be the most promising approach for understanding the circulation, (re)production, and (re)configuration of meanings of bio-objects, but also to interpret the relationship between media and science. On the basis of a few selected examples, this paper highlights how media function as a primary arena for the (re)production and (re)configuration of scientific and biomedical information with regards to bio-objects in the public sphere in general, and toward decision-makers, interest groups, and the public in specific.

SLS-PLAN-IT: A knowledge-based blackboard scheduling system for Spacelab life sciences missions

NASA Technical Reports Server (NTRS)

Kao, Cheng-Yan; Lee, Seok-Hua

1992-01-01

The primary scheduling tool in use during the Spacelab Life Science (SLS-1) planning phase was the operations research (OR) based, tabular form Experiment Scheduling System (ESS) developed by NASA Marshall. PLAN-IT is an artificial intelligence based interactive graphic timeline editor for ESS developed by JPL. The PLAN-IT software was enhanced for use in the scheduling of Spacelab experiments to support the SLS missions. The enhanced software SLS-PLAN-IT System was used to support the real-time reactive scheduling task during the SLS-1 mission. SLS-PLAN-IT is a frame-based blackboard scheduling shell which, from scheduling input, creates resource-requiring event duration objects and resource-usage duration objects. The blackboard structure is to keep track of the effects of event duration objects on the resource usage objects. Various scheduling heuristics are coded in procedural form and can be invoked any time at the user's request. The system architecture is described along with what has been learned with the SLS-PLAN-IT project.

Investigating Image Formation with a Camera Obscura: a Study in Initial Primary Science Teacher Education

NASA Astrophysics Data System (ADS)

Muñoz-Franco, Granada; Criado, Ana María; García-Carmona, Antonio

2018-04-01

This article presents the results of a qualitative study aimed at determining the effectiveness of the camera obscura as a didactic tool to understand image formation (i.e., how it is possible to see objects and how their image is formed on the retina, and what the image formed on the retina is like compared to the object observed) in a context of scientific inquiry. The study involved 104 prospective primary teachers (PPTs) who were being trained in science teaching. To assess the effectiveness of this tool, an open questionnaire was applied before (pre-test) and after (post-test) the educational intervention. The data were analyzed by combining methods of inter- and intra-rater analysis. The results showed that more than half of the PPTs advanced in their ideas towards the desirable level of knowledge in relation to the phenomena studied. The conclusion reached is that the camera obscura, used in a context of scientific inquiry, is a useful tool for PPTs to improve their knowledge about image formation and experience in the first person an authentic scientific inquiry during their teacher training.

A strategy for Earth science from space in the 1980s. Part 1: Solid earth and oceans

NASA Technical Reports Server (NTRS)

1982-01-01

The report develops a ten-year science strategy for investigating the solid earth and dynamics of world oceans from Earth orbit. The strategy begins from the premise that earth studies have proceeded to the point where further advances in understanding Earth processes must be based on a global perspective and that the U.S. is technically ready to begin a global study approach from Earth orbit. The major areas of study and their fundamental problems are identified. The strategy defines the primary science objectives to be addressed and the essential measurements and precision to achieve them.

The SMAP satellite was successfully launched January 31st 2015, and began acquiring Earth observation data following in-orbit sensor calibration. Global data products derived from the SMAP L-band microwave measurements include Level 1 calibrated and geolocated radiometric brightness temperatures, Level 23 surface soil moisture and freezethaw geophysical retrievals mapped to a fixed Earth grid, and model enhanced Level 4 data products for surface to root zone soil moisture and terrestrial carbon (CO2) fluxes. The post-launch SMAP mission CalVal Phase had two primary objectives for each science product team: 1) calibrate, verify, and improve the performance of the science algorithms, and 2) validate accuracies of the science data products as specified in the L1 science requirements. This report provides analysis and assessment of the SMAP Level 4 Carbon (L4_C) product pertaining to the validated release. The L4_C validated product release effectively replaces an earlier L4_C beta-product release (Kimball et al. 2015). The validated release described in this report incorporates a longer data record and benefits from algorithm and CalVal refinements acquired during the SMAP post-launch CalVal intensive period. The SMAP L4_C algorithms utilize a terrestrial carbon flux model informed by SMAP soil moisture inputs along with optical remote sensing (e.g. MODIS) vegetation indices and other ancillary biophysical data to estimate global daily net ecosystem CO2 exchange (NEE) and component carbon fluxes for vegetation gross primary production (GPP) and ecosystem respiration (Reco). Other L4_C product elements include surface (10 cm depth) soil organic carbon (SOC) stocks and associated environmental constraints to these processes, including soil moisture and landscape freeze/thaw (FT) controls on GPP and respiration (Kimball et al. 2012). The L4_C product encapsulates SMAP carbon cycle science objectives by: 1) providing a direct link between terrestrial carbon fluxes and underlying FT and soil moisture constraints to these processes, 2) documenting primary connections between terrestrial water, energy and carbon cycles, and 3) improving understanding of terrestrial carbon sink activity in northern ecosystems. There are no L1 science requirements for the L4_C product; however self-imposed requirements have been established focusing on NEE as the primary product field for validation, and on demonstrating L4_C accuracy and success in meeting product science requirements (Jackson et al. 2012). The other L4_C product fields also have strong utility for carbon science applications; however, analysis of these other fields is considered secondary relative to primary validation activities focusing on NEE. The L4_C targeted accuracy requirements are to meet or exceed a mean unbiased accuracy (ubRMSE) for NEE of 1.6 g C/sq m/d or 30 g C/sq m/yr, emphasizing northern (45N) boreal and arctic ecosystems; this is similar to the estimated accuracy level of in situ tower eddy covariance measurement-based observations (Baldocchi 2008).

Primary school children and teachers discover the nature and science of planet Earth and Mars

For various reasons primary schools emphasise language and calculus rather than natural sciences. When science is taught at all, examination systems often favour technological tricks and knowledge of the 'right' answer over the process of investigation and logical reasoning towards that answer. Over the long term, this is not conducive to curiosity and scientific attitude in large parts of the population. Since the problem is more serious in primary than in secondary education, and as children start their school career with a natural curiosity and great energy to explore their world, we focus our efforts on primary school teachers in close collaboration with teachers and researchers. Our objective was to spark children's curiosity and their motivation to learn and discover, as well as to help teachers develop self-afficacy in science education. To this end we developed a three-step program with a classroom game and sand-box experiments related to planet Earth and Mars. The classroom game Expedition Mundus simulates science in its focus on asking questions, reasoning towards answers on the basis of multiple sources and collaboration as well as growth of knowledge. Planet Mundus is entirely fictitional to avoid differences in foreknowledge between pupils. The game was tested in hundreds of classes in primary schools and the first years of secondary education and was printed (in Dutch) and distributed over thousands of schools as part of teacher education through university science hubs. Expedition Mundus was developed by the Young Academy of the Royal Netherlands Academy of Arts and Sciences and De Praktijk. The tested translations in English and German are available on http://www.expeditionmundus.org. Following the classroom game, we conducted simple landscape experiments in sand boxes supported by google earth imagery of real rivers, fans and deltas on Earth and Mars. This was loosely based on our fluvial morphodynamics research. This, in the presence of a scientist, evoked questions that were developed by Aristotelian discourse towards researchable empirical questions. Here teachers and scientists closely collaborated to develop effective queries. The final questions were then investigated by couples of pupils following the empirical cycle up to the point of a poster presentation.

The primary objective of this project was to engage members of the public in an active and balanced deliberative discussion about the social, ethical, legal, environmental, and policy issues arising from nanotechnologies. A second but equally important objective was to interest members of the public in learning more about science and technology and nanotechnology specifically by understanding how it will affect their lives. The objectives were met through a series of electronic and face-to-face citizen forums conducted in conjunction with three Fred Friendly Seminars being taped on the University of California, Berkeley campus in partnership with Lawrence Hall of Sciencemore » (this forum was conducted in partnership with the St. Louis Science Center); the Boston Museum of Science in Boston, MA; and the State Museum of South Carolina in Columbia, South Carolina. The topical area for each forum paralleled the content of the Fred Friendly Seminars series being taped at each location, but specific topics/issues were drawn from the concerns and interests of the communities. The three topical areas included Environmental Impact (St. Louis), Privacy vs. Security (Boston), and Health and Enhancement (Columbia). The PI and project leader worked with the local science centers to identify stakeholder groups, such as academic, corporate and government scientists; environmental advocates; business leaders; science and technology journalists; and public policy makers within each community. Representatives from each group along with members of the general public were invited to participate in a series of on line and in person deliberations that were designed to provide basic information about the science, its potential benefits and risks, and avenues for public participation in policy formulation. On line resources were designed and managed by ScienceVIEW at Lawrence Hall of Science and Earth & Sky, Inc. The activities at each site were evaluated by Inverness Research Associates to assess whether they have achieved the objectives.« less

Teaching students to read the primary literature using POGIL activities.

PubMed

Murray, Tracey Arnold

2014-01-01

The ability to read, interpret, and evaluate articles in the primary literature are important skills that science majors will use in graduate school and professional life. Because of this, it is important that students are not only exposed to the primary literature in undergraduate education, but also taught how to read and interpret these articles. To achieve this objective, POGIL activities were designed to use the primary literature in a majors biochemistry sequence. Data show that students were able to learn content from the literature without separate activities or lecture. Students also reported an increase in comfort and confidence in approaching the literature as a result of the activities.

Werner, Gerhard

2004-09-01

Under the assumption that nervous systems form a distinct category among the objects in Nature, applying metaphors of psychological and behavioral science disciplines is flawed and invites confusion. Moreover, such practices obscure and detract from the primary task of Neurophysiology: to investigate the intrinsic properties of nervous systems, uncontaminated with concepts borrowed from other disciplines.

A Comparison of Student Teachers' Beliefs from Four Different Science Teaching Domains Using a Mixed Methods Design

NASA Astrophysics Data System (ADS)

Markic, Silvija; Eilks, Ingo

2012-03-01

The study presented in this paper integrates data from four combined research studies, which are both qualitative and quantitative in nature. The studies describe freshman science student teachers' beliefs about teaching and learning. These freshmen intend to become teachers in Germany in one of four science teaching domains (secondary biology, chemistry, and physics, respectively, as well as primary school science). The qualitative data from the first study are based on student teachers' drawings of themselves in teaching situations. It was formulated using Grounded Theory to test three scales: Beliefs about Classroom Organisation, Beliefs about Teaching Objectives, and Epistemological Beliefs. Three further quantitative studies give insight into student teachers' curricular beliefs, their beliefs about the nature of science itself, and about the student- and/or teacher-centredness of science teaching. This paper describes a design to integrate all these data within a mixed methods framework. The aim of the current study is to describe a broad, triangulated picture of freshman science student teachers' beliefs about teaching and learning within their respective science teaching domain. The study reveals clear tendencies between the sub-groups. The results suggest that freshman chemistry and-even more pronouncedly-freshman physics student teachers profess quite traditional beliefs about science teaching and learning. Biology and primary school student teachers express beliefs about their subjects which are more in line with modern educational theory. The mixed methods approach towards the student teachers' beliefs is reflected upon and implications for science education and science teacher education are discussed.

Secondary Science Teachers' and Students' Involvement in a Primary School Community of Science Practice: How It Changed Their Practices and Interest in Science

NASA Astrophysics Data System (ADS)

Forbes, Anne; Skamp, Keith

2016-02-01

MyScience is a primary science education initiative in which being in a community of practice is integral to the learning process. In this initiative, stakeholder groups—primary teachers, primary students and mentors—interact around the `domain' of `investigating scientifically'. This paper builds on three earlier publications and interprets the findings of the views of four secondary science teachers and five year 9 secondary science students who were first-timer participants—as mentors—in MyScience. Perceptions of these mentors' interactions with primary students were analysed using attributes associated with both `communities of practice' and the `nature of science'. Findings reveal that participation in MyScience changed secondary science teachers' views and practices about how to approach the teaching of science in secondary school and fostered primary-secondary links. Year 9 students positively changed their views about secondary school science and confidence in science through participation as mentors. Implications for secondary science teaching and learning through participation in primary school community of science practice settings are discussed.

Using systems science for population health management in primary care.

Li, Yan; Kong, Nan; Lawley, Mark A; Pagán, José A

2014-10-01

Population health management is becoming increasingly important to organizations managing and providing primary care services given ongoing changes in health care delivery and payment systems. The objective of this study is to show how systems science methodologies could be incorporated into population health management to compare different interventions and improve health outcomes. The New York Academy of Medicine Cardiovascular Health Simulation model (an agent-based model) and data from the Behavioral Risk Factor Surveillance System were used to evaluate a lifestyle program that could be implemented in primary care practice settings. The program targeted Medicare-age adults and focused on improving diet and exercise and reducing weight. The simulation results suggest that there would be significant reductions projected in the proportion of the Medicare-age population with diabetes after the implementation of the proposed lifestyle program for a relatively long term (3 and 5 years). Similar results were found for the subpopulations with high cholesterol, but the proposed intervention would not have a significant effect in the proportion of the population with hypertension over a time period of <5 years. Systems science methodologies can be useful to compare the health outcomes of different interventions. These tools can become an important component of population health management because they can help managers and other decision makers evaluate alternative programs in primary care settings. © The Author(s) 2014.

2012-01-01

The Mars Reconnaissance Orbiter (MRO) is an orbiting asset that performs remote sensing observations in order to characterize the surface, subsurface and atmosphere of Mars. To support upcoming NASA Mars Exploration Program Office objectives, MRO will be used as a relay communication link for the Mars Science Laboratory (MSL) mission during the MSL Entry, Descent and Landing sequence. To do so, MRO Navigation must synchronize the MRO Primary Science Orbit (PSO) with a set of target conditions requested by the MSL Navigation Team; this may be accomplished via propulsive maneuvers. This paper describes the MRO Navigation strategy for and operational performance of MSL EDL relay telecommunication support.

From Students to Teachers: Investigating the Science Teaching Efficacy Beliefs and Experiences of Graduate Primary Teachers

NASA Astrophysics Data System (ADS)

Deehan, James; Danaia, Lena; McKinnon, David H.

2018-03-01

The science achievement of primary students, both in Australia and abroad, has been the subject of intensive research in recent decades. Consequently, much research has been conducted to investigate primary science education. Within this literature, there is a striking juxtaposition between tertiary science teaching preparation programs and the experiences and outcomes of both teachers and students alike. Whilst many tertiary science teaching programs covary with positive outcomes for preservice teachers, reports of science at the primary school level continue to be problematic. This paper begins to explore this apparent contradiction by investigating the science teaching efficacy beliefs and experiences of a cohort of graduate primary teachers who had recently transitioned from preservice to inservice status. An opportunity sample of 82 primary teachers responded to the science teaching efficacy belief instrument A (STEBI-A), and 10 graduate teachers provided semi-structured interview data. The results showed that participants' prior science teaching efficacy belief growth, which occurred during their tertiary science education, had remained durable after they had completed their teaching degrees and began their careers. Qualitative data showed that their undergraduate science education had had a positive influence on their science teaching experiences. The participants' school science culture, however, had mixed influences on their science teaching. The findings presented within this paper have implications for the direction of research in primary science education, the design and assessment of preservice primary science curriculum subjects and the role of school contexts in the development of primary science teachers.

Accurate and complete reporting of study methods, results and interpretation are essential components for any scientific process, allowing end-users to evaluate the internal and external validity of a study. When animals are used in research, excellence in reporting is expected as a matter of continued ethical acceptability of animal use in the sciences. Our primary objective was to assess completeness of reporting for a series of studies relevant to mitigation of pain in neonatal piglets undergoing routine management procedures. Our second objective was to illustrate how authors can report the items in the Reporting guidElines For randomized controLled trials for livEstoCk and food safety (REFLECT) statement using examples from the animal welfare science literature. A total of 52 studies from 40 articles were evaluated using a modified REFLECT statement. No single study reported all REFLECT checklist items. Seven studies reported specific objectives with testable hypotheses. Six studies identified primary or secondary outcomes. Randomization and blinding were considered to be partially reported in 21 and 18 studies, respectively. No studies reported the rationale for sample sizes. Several studies failed to report key design features such as units for measurement, means, standard deviations, standard errors for continuous outcomes or comparative characteristics for categorical outcomes expressed as either rates or proportions. In the discipline of animal welfare science, authors, reviewers and editors are encouraged to use available reporting guidelines to ensure that scientific methods and results are adequately described and free of misrepresentations and inaccuracies. Complete and accurate reporting increases the ability to apply the results of studies to the decision-making process and prevent wastage of financial and animal resources.

NASA James Webb Space Telescope (JWST) will search for the first luminous objects of the Universe to help answer fundamental questions about how the Universe came to look like it does today. At 6.5 meters in diameter, JWST will be the world's largest space telescope. Its architecture, e.g. aperture, wavelength range and operating temperature, is driven by JWST's science objectives. Introduction: Scheduled to start its 5 year mission after 2018, JWST will study the origin and evolution of galaxies, stars and planetary systems. Its science mission is to: Identify the first bright objects that formed in the early Universe, and follow the ionization history. Determine how galaxies form. Determine how galaxies and dark matter, including gas, stars, metals, overall morphology and active nuclei evolved to the present day. Observe the birth and early development of stars and the formation of planets. And, study the physical and chemical properties of solar systems for the building blocks of Life. Principle: To accomplish the JWST science objectives requires a larger aperture infrared cryogenic space telescope. A large aperture is required because the objects are very faint. The infrared spectral range is required because the objects are so far away that their ultraviolet and visible wavelength spectral lines are red-shifted into the infrared. Because the telescope is infrared, it needs to be cryogenic. And, because of the telescope is infrared, it must operate above the Earth's atmosphere, i.e. in space. JWST is probably the single most complicated mission that humanity has attempted. It is certainly the most difficult optical fabrication and testing challenge of our generation. The JWST 6.5 m diameter primary mirror is nearly a parabola with a conic constant of -0.9967 and radius of curvature at 30K of 15.880 m. The primary mirror is divided into 18 segments with 3 different prescriptions; each with its own off-axis distance and aspheric departure. The radius of curvature for all 18 segments must match to +/- 0.150 mm at 30K. JWST is diffraction limited at 2 micrometers which translates into a transmitted wavefront specification of 156 nm rms. Of that amount, 50 nm rms is allocated to the primary mirror. Each segment is allocated 22 nm rms surface error. At the start of the JWST program, the capability to make such a mirror did not exist. In 1996, NASA began a systematic and comprehensive mirror technology development effort which resulted in JWST. This program resulted in a qualified mirror fabrication process being approved in 2006. Today, all JWST primary mirror segments meet their requirements and are on schedule for a 2018 launch. The next step is system level assembly, integration and test. Ambient tests will be conducted at Goddard Space Flight Center and cryogenic system level testing will be performed in Chamber A at the Johnson Space Center.

Benford, Dominic J.

2013-01-01

Submission Overview: Our primary objective is to convey a sense of the significant advances possible in astrophysics investigations for major Cosmic Origins COR program goals with a 2.4m telescope asset outfitted with one or more advanced UV visible instruments. Several compelling science objectives were identified based on community meetings these science objectives drove the conceptual design of instruments studied by the COR Program Office during July September 2012. This RFI submission encapsulates the results of that study, and suggests that a more detailed look into the instrument suite should be conducted to prove viability and affordability to support the demonstrated scientific value. This study was conducted in the context of a larger effort to consider the options available for a mission to dispose safely of Hubble hence, the overall architecture considered for the mission we studied for the 2.4m telescope asset included resource sharing. This mitigates combined cost and risk and provides naturally for a continued US leadership role in astrophysics with an advanced, general-purpose UV visible space telescope.

Bio-objects and the media: the role of communication in bio-objectification processes

Maeseele, Pieter; Allgaier, Joachim; Martinelli, Lucia

2013-01-01

The representation of biological innovations in and through communication and media practices is vital for understanding the nature of “bio-objects” and the process we call “bio-objectification.” This paper discusses two ideal-typical analytical approaches based on different underlying communication models, ie, the traditional (science- and media-centered) and media sociological (a multi-layered process involving various social actors in defining the meanings of scientific and technological developments) approach. In this analysis, the latter is not only found to be the most promising approach for understanding the circulation, (re)production, and (re)configuration of meanings of bio-objects, but also to interpret the relationship between media and science. On the basis of a few selected examples, this paper highlights how media function as a primary arena for the (re)production and (re)configuration of scientific and biomedical information with regards to bio-objects in the public sphere in general, and toward decision-makers, interest groups, and the public in specific.

Influencing Intended Teaching Practice: Exploring pre-service teachers' perceptions of science teaching resources

NASA Astrophysics Data System (ADS)

Cooper, Grant; Kenny, John; Fraser, Sharon

2012-08-01

Many researchers have identified and expressed concern over the state of science education internationally, but primary teachers face particular obstacles when teaching science due to their poor science background and low confidence with science. Research has suggested that exemplary resources, or units that work, may be an effective way to support primary teachers. This study explores the effect of one such resource on the intentions of pre-service primary teachers to teach science. The resource in question is Primary Connections, a series of learning resources produced by the Australian Academy of Science specifically designed for primary science. Evaluative studies of Primary Connections have indicated its efficacy with practising primary teachers but there is little evidence of its impact upon pre-service teachers. The purpose of this study was to investigate how effective these quality teaching resources were in influencing the intentions of primary pre-service teachers to teach science after they graduated. The theory of planned behaviour highlighted the linkage between the intentions of the pre-service teachers to teach science, and their awareness of and experiences with using Primary Connections during their education studies. This enabled key factors to be identified which influenced the intentions of the pre-service teachers to use Primary Connections to teach science after they graduate. The study also provided evidence of how quality science teaching resources can be effectively embedded in a teacher education programme as a means of encouraging and supporting pre-service teachers to teach science.

SweepSAR Sensor Technology for Dense Spatial and Temporal Coverage of Earth Change

NASA Astrophysics Data System (ADS)

Rosen, P. A.

2016-12-01

Since the 2007 National Academy of Science "Decadal Survey" report, NASA has been studying concepts for a Synthetic Aperture Radar (SAR) mission to determine Earth change in three disciplines - ecosystems, solid earth, and cryospheric sciences. NASA has joined forces with the Indian Space Research Organisation (ISRO) to fulfill these objectives. The NASA-ISRO SAR (NISAR) mission is now in development for a launch in 2021. The mission's primary science objectives are codified in a set of science requirements to study Earth land and ice deformation, and ecosystems, globally with 12-day sampling over all land and ice-covered surfaces throughout the mission life. The US and Indian science teams share global science objectives; in addition, India has developed a set of local objectives in agricultural biomass estimation, Himalayan glacier characterization, and coastal ocean measurements in and around India. Both the US and India have identified agricultural and infrastructure monitoring, and disaster response as high priority applications for the mission. With this range of science and applications objectives, NISAR has demanding coverage, sampling, and accuracy requirements. The system requires a swath of over 240 km at 3-10 m SAR imaging resolution, using full polarimetry where needed. Given the broad range of phenomena and wide range of sensitivities needed, NISAR carries two radars, one operating at L-band (24 cm wavelength) and the other at S-band (10 cm wavelength). The system uses a new "scan-on-receive" ("SweepSAR") technology at both L-band and S-band, that enables full swath coverage without loss of resolution or polarimetric diversity. Both radars can operate simultaneously. The L-band system is being designed to operate up to 50 minutes per orbit, and the S-band system up to 10 minutes per orbit. The orbit will be controlled to within 300 m for repeat-pass interferometry measurements. This unprecedented coverage in space, time, polarimetry, and frequency, will add a new and rich data set to the international constellation of sensors studying Earth surface change. In this talk, we will describe the mission's expected contributions to geodetic imaging in support of time-series analysis of dynamic changes of Earth's surface.

Explore the concept of “light” and its interaction with matter: an inquiry-based science education project in primary school

NASA Astrophysics Data System (ADS)

Varela, P.; Costa, M. F.

2015-04-01

The exploration process leading to the understanding of physical phenomena, such as light and its interaction with matter, raises great interest and curiosity in children. However, in most primary schools, children rarely have the opportunity to conduct science activities in which they can engage in an enquiry process even if by the action of the teacher. In this context, we have organised several in-service teacher training courses and carried out several pedagogic interventions in Portuguese primary schools, with the aim of promoting inquiry- based science education. This article describes one of those projects, developed with a class of the third grade, which explored the curricular topic “Light Experiments”. Various activities were planned and implemented, during a total of ten hours spread over five lessons. The specific objectives of this paper are: to illustrate and analyse the teaching and learning process promoted in the classroom during the exploration of one of these lessons, and to assess children's learning three weeks after the lessons. The results suggest that children made significant learning which persisted. We conclude discussing some processes that stimulated children’ learning, including the importance of teacher questioning in scaffolding children's learning and some didactic implications for teacher training.

`You Have to Give Them Some Science Facts': Primary Student Teachers' Early Negotiations of Teacher Identities in the Intersections of Discourses About Science Teaching and About Primary Teaching

NASA Astrophysics Data System (ADS)

Danielsson, Anna T.; Warwick, Paul

2014-04-01

In the broadest sense, the goal for primary science teacher education could be described as preparing these teachers to teach for scientific literacy. Our starting point is that making such science teaching accessible and desirable for future primary science teachers is dependent not only on their science knowledge and self-confidence, but also on a whole range of interrelated sociocultural factors. This paper aims to explore how intersections between different Discourses about primary teaching and about science teaching are evidenced in primary school student teachers' talk about becoming teachers. The study is founded in a conceptualisation of learning as a process of social participation. The conceptual framework is crafted around two key concepts: Discourse (Gee 2005) and identity (Paechter, Women's Studies International Forum, 26(1):69-77, 2007). Empirically, the paper utilises semi-structured interviews with 11 primary student teachers enrolled in a 1-year Postgraduate Certificate of Education course. The analysis draws on five previously identified teacher Discourses: `Teaching science through inquiry', `Traditional science teacher', `Traditional primary teacher', `Teacher as classroom authority', and `Primary teacher as a role model' (Danielsson and Warwick, International Journal of Science Education, 2013). It explores how the student teachers, at an early stage in their course, are starting to intersect these Discourses to negotiate their emerging identities as primary science teachers.

The Pavilion Lake Research Project (PLRP) is a unique platform where the combination of scientific research and human space exploration concepts can be tested in an underwater spaceflight analog environment. The 2015 PLRP field season was performed at Pavilion Lake, Canada, where science-driven exploration techniques focusing on microbialite characterization and acquisition were evaluated within the context of crew and robotic extravehicular activity (EVA) operations. The primary objectives of this analog study were to detail the capabilities, decision-making process, and operational concepts required to meet non-simulated scientific objectives during 5-minute one-way communication latency utilizing crew and robotic assets. Furthermore, this field study served as an opportunity build upon previous tests at PLRP, NASA Desert Research and Technology Studies (DRATS), and NASA Extreme Environment Mission Operations (NEEMO) to characterize the functional roles and responsibilities of the personnel involved in the distributed flight control team and identify operational constraints imposed by science-driven EVA operations. The relationship and interaction between ground and flight crew was found to be dependent on the specific scientific activities being addressed. Furthermore, the addition of a second intravehicular operator was found to be highly enabling when conducting science-driven EVAs. Future human spaceflight activities will need to cope with the added complexity of dynamic and rapid execution of scientific priorities both during and between EVA execution to ensure scientific objectives are achieved.

Lessons learned: the switch from VMS to UNIX operations for the STScI's Science and Mission Scheduling Branch

NASA Astrophysics Data System (ADS)

Adler, David S.; Workman, William M., III; Chance, Don

2004-09-01

The Science and Mission Scheduling Branch (SMSB) of the Space Telescope Science Institute (STScI) historically operated exclusively under VMS. Due to diminished support for VMS-based platforms at STScI, SMSB recently transitioned to Unix operations. No additional resources were available to the group; the project was SMSB's to design, develop, and implement. Early decisions included the choice of Python as the primary scripting language; adoption of Object-Oriented Design in the development of base utilities; and the development of a Python utility to interact directly with the Sybase database. The project was completed in January 2004 with the implementation of a GUI to generate the Command Loads that are uplinked to HST. The current tool suite consists of 31 utilities and 271 tools comprising over 60,000 lines of code. In this paper, we summarize the decision-making process used to determine the primary scripting language, database interface, and code management library. We also describe the finished product and summarize lessons learned along the way to completing the project.

Summary of the Science performed onboard the International Space Station during Increments 12 and 13

NASA Technical Reports Server (NTRS)

Jules, Kenol

2007-01-01

By September of 2007, continuous human presence on the International Space Station will reach a milestone of eighty months. The many astronauts and cosmonauts, who live onboard the station during the last fourteen Increments over that time span, spend their time building the station as well as performing science on a daily basis. Over those eighty months, the U.S astronauts crew members logged over 2954 hours of research time. Far more research time has been accumulated by experiments controlled by investigators on the ground. The U.S astronauts conducted over one hundred and twenty six (126) science investigations. From these hundred and twenty six science investigations, many were operated across multiple Increments. The crew also installed, activated and operated nine (9) science racks that supported six science disciplines ranging from material sciences to life science. By the end of Increment 14, a total of 5083 kg of research rack mass were ferried to the station as well as 5021 kg of research mass. The objectives of this paper are three-fold. (1) To briefly review the science conducted on the International Space Station during the previous eleven Increments; (2) to discuss in detail the science investigations that were conducted on the station during Increments 12 and 13. The discussion will focus mainly on the primary objectives of each investigation and their associated hypotheses that were investigated during these two Increments. Also, some preliminary science results will be discussed for each of the investigation as science results availability permit. (3) The paper will briefly touch on what the science complement planning was and what was actually accomplished due to real time science implementation and challenges during these two Increments in question to illustrate the challenges of daily science activity while the science platform is under construction. Finally, the paper will briefly discuss the science research complements for the other two Increments, Increments 14 and 15, to preview how much science might be accomplished during these two Increments.

James Webb Space Telescope Optical Telescope Element (OTE) is a three mirror anastigmat consisting of a 6.5 m primary mirror (PM), secondary mirror (SM) and a tertiary mirror. The primary mirror is made out of 18 segments. The telescope and instruments will be assembled at Goddard Space Flight Center (GSFC) to make it the Optical Telescope Element-Integrated Science Instrument Module (OTIS). The OTIS will go through environmental testing at GSFC before being transported to Johnson Space Center for testing at cryogenic temperature. The objective of the primary mirror Center of Curvature test (CoC) is to characterize the PM before and after the environmental testing for workmanship. This paper discusses the CoC test including both a surface figure test and a new method for characterizing the state of the primary mirror using high speed dynamics interferometry.

Polycarbonate crowns for primary teeth revisited: restorative options, technique and case reports.

Venkataraghavan, Karthik; Chan, John; Karthik, Sandhya

2014-01-01

Esthetics by definition is the science of beauty - that particular detail of an animate or inanimate object that makes it appealing to the eye. In the modern, civilized, and cosmetically conscious world, well-contoured and well-aligned white teeth set the standard for beauty. Such teeth are not only considered attractive but are also indicative of nutritional health, self esteem, hygienic pride, and economic status. Numerous treatment approaches have been proposed to address the esthetics and retention of restorations in primary teeth. Even though researchers have claimed that certain restorations are better than the others, particularly owing to the issues mentioned above, the search for the ideal esthetic restoration for the primary teeth continues. This paper revisits and attempts to reintroduce the full coverage restoration, namely, polycarbonate crown, for use in primary anterior teeth.

OBJECTIVE To characterize the integration of phytotherapy in primary health care in Brazil. METHODS Journal articles and theses and dissertations were searched for in the following databases: SciELO, Lilacs, PubMed, Scopus, Web of Science and Theses Portal Capes, between January 1988 and March 2013. We analyzed 53 original studies on actions, programs, acceptance and use of phytotherapy and medicinal plants in the Brazilian Unified Health System. Bibliometric data, characteristics of the actions/programs, places and subjects involved and type and focus of the selected studies were analyzed. RESULTS Between 2003 and 2013, there was an increase in publications in different areas of knowledge, compared with the 1990-2002 period. The objectives and actions of programs involving the integration of phytotherapy into primary health care varied: including other treatment options, reduce costs, reviving traditional knowledge, preserving biodiversity, promoting social development and stimulating inter-sectorial actions. CONCLUSIONS Over the past 25 years, there was a small increase in scientific production on actions/programs developed in primary care. Including phytotherapy in primary care services encourages interaction between health care users and professionals. It also contributes to the socialization of scientific research and the development of a critical vision about the use of phytotherapy and plant medicine, not only on the part of professionals but also of the population.

Mobile Devices and Apps as Scaffolds to Science Learning in the Primary Classroom

NASA Astrophysics Data System (ADS)

Falloon, Garry

2017-12-01

Considerable work over many years has explored the contribution technology can make to science learning, at all levels of education. In the school sector, historically this has focused on the use of fixed, desktop-based or semi-mobile laptop systems for purposes such as experiment data collection or analysis, or as a means of engaging or motivating interest in science. However, the advent of mobile devices such as iPads supported by a huge array of low or no cost apps, means that new opportunities are becoming available for teachers to explore how these resources may be useful for supporting `hands on' science learning. This article reports outcomes from a study of primary (elementary) school students' use of a series of apps integrated with practical science activities, in a topic exploring Energy concepts. It used an innovative display capture tool to examine how the students used the apps and features of their iPads to scaffold their practical work at different stages during the experiments. Results identify device functions and app-based scaffolds that assisted these students to structure their experiments, understand procedures, think about the influence of variables and communicate and share outcomes. However, they also discovered limitations in the apps' ability to support conceptual knowledge development, identifying the critical role of teachers and the importance of task structure and design to ensuring conceptual knowledge objectives are met.

Research Objectives for Human Missions in the Proving Ground of Cis-Lunar Space

Introduction: This talk will introduce the preliminary findings in support of NASA's Future Capabilities Team. In support of the ongoing studies conducted by NASA's Future Capabilities Team, we are tasked with collecting research objectives for the Proving Ground activities. The objectives could include but are certainly not limited to: demonstrating crew well being and performance over long duration missions, characterizing lunar volatiles, Earth monitoring, near Earth object search and identification, support of a far-side radio telescope, and measuring impact of deep space environment on biological systems. Beginning in as early as 2023, crewed missions beyond low Earth orbit will begin enabled by the new capabilities of the SLS and Orion vehicles. This will initiate the "Proving Ground" phase of human exploration with Mars as an ultimate destination. The primary goal of the Proving Ground is to demonstrate the capability of suitably long duration spaceflight without need of continuous support from Earth, i.e. become Earth Independent. A major component of the Proving Ground phase is to conduct research activities aimed at accomplishing major objectives selected from a wide variety of disciplines including but not limited to: Astronomy, Heliophysics, Fundamental Physics, Planetary Science, Earth Science, Human Systems, Fundamental Space Biology, Microgravity, and In Situ Resource Utilization. Mapping and prioritizing the most important objectives from these disciplines will provide a strong foundation for establishing the architecture to be utilized in the Proving Ground. Possible Architectures: Activities and objectives will be accomplished during the Proving Ground phase using a deep space habitat. This habitat will potentially be accompanied by a power/propulsion bus capable of moving the habitat to accomplish different objectives within cis-lunar space. This architecture can also potentially support staging of robotic and tele-robotic assets as well as sample-return. As mission durations increase from 20 days to 300 days, increasingly ambitious objectives may be undertaken including rendezvous with an asteroid or other near-Earth object. Research activities can occur inside the habitat, outside the habitat, via externally mounted instruments, or using free flying satellites/landers. Research Objectives: Primary mission objectives are listed below. In order to help define details of the mission architecture, including the means by which the architecture can be supported, more specific research objectives are needed. Title/Objective Crew Transportation/Provide ability to transport at least four crew to cislunar space Heavy Launch Capability/Provide beyond LEO launch capabilities to include crew, co-manisfested payloads, and large cargo In-Space Propulsion/Provide in-sapce propulsion capabilities to send crew and cargo on Mars-class mission durations and distances Deep Space Navigation and Communication/Provide and validate cislunar and Mars system navigation and communication Science/Enable science community objectives Deep Space Operations/Provide deep-space operation capabilities: EVA, Staging, Logistics, Human-robotic integration, Autonomous operations In-Situ Resource Utilization/Understand the nature and distribution of volatiles and extraction techniques, and decide on their potential use in the human exploration architecture Deep Space Habitation/Provide beyond LEO habitation systems sufficient to support at least four crew on Mars-class mission durations and dormancy Crew Health/Validate crew health, performance, and mitigation protocols for Mars-class missions Reference: .NASA, NASA's Journey to Mars: Pioneering Next Steps in Space Exploration. 34 ( October 8, 2015).

Introduction: This talk will introduce the preliminary findings in support of NASA's Future Capabilities Team. In support of the ongoing studies conducted by NASA's Future Capabilities Team, we are tasked with collecting re-search objectives for the Proving Ground activities. The objectives could include but are certainly not limited to: demonstrating crew well being and performance over long duration missions, characterizing lunar volatiles, Earth monitoring, near Earth object search and identification, support of a far-side radio telescope, and measuring impact of deep space environment on biological systems. Beginning in as early as 2023, crewed missions beyond low Earth orbit will be enabled by the new capabilities of the SLS and Orion vehicles. This will initiate the "Proving Ground" phase of human exploration with Mars as an ultimate destination. The primary goal of the Proving Ground is to demonstrate the capability of suitably long dura-tion spaceflight without need of continuous support from Earth, i.e. become Earth Independent. A major component of the Proving Ground phase is to conduct research activities aimed at accomplishing major objectives selected from a wide variety of disciplines including but not limited to: Astronomy, Heliophysics, Fun-damental Physics, Planetary Science, Earth Science, Human Systems, Fundamental Space Biology, Microgravity, and In Situ Resource Utilization. Mapping and prioritizing the most important objectives from these disciplines will provide a strong foundation for establishing the architecture to be utilized in the Proving Ground. Possible Architectures: Activities and objectives will be accomplished during the Proving Ground phase using a deep space habitat. This habitat will potentially be accompanied by a power/propulsion bus capable of moving the habitat to accomplish different objectives within cis-lunar space. This architecture can also potentially support stag-ing of robotic and tele-robotic assets as well as sample-return. As mission durations increase from 20 days to 300 days, increasingly ambitious objectives may be undertaken in-cluding rendezvous with an asteroid or other near-Earth object. Research activities can occur inside the habitat, outside the habitat, via externally mounted instruments, or using free flying satellites/landers. Research Objectives: Primary mission objectives are listed below. In order to help define details of the mission architecture, including the means by which the architecture can be supported, more specific research objectives are needed. Title/Objective • Crew Transportation/Provide ability to transport at least four crew to cislunar space • Heavy Launch Capability/Provide beyond-LEO launch capabilities to include crew, co-manisfested pay-loads, and large cargo • In-Space Propulsion/Provide in-space propulsion capabilities to send crew and cargo on Mars-class mission durations and distances • Deep Space Navigation and Communication/Provide and validate cislunar and Mars system navigation and communication • Science/Enable science community objectives • Deep Space Operations/Provide deep-space operation capabilities: EVA, Staging, Logistics, Human-robotic integration, Autonomous operations • In-Situ Resource Utilization/Understand the nature and distribution of volatiles and extraction techniques, and decide on their potential use in the human exploration architecture • Deep Space Habitation/Provide beyond-LEO habitation systems sufficient to support at least four crew on Mars-class mission durations and dormancy • Crew Health/Validate crew health, performance, and mitigation protocols for Mars-class missions Reference: NASA, NASA's Journey to Mars: Pioneering Next Steps in Space Exploration. 34 ( October 8, 2015).

Balancing Science Objectives and Operational Constraints: A Mission Planner's Challenge

NASA Technical Reports Server (NTRS)

Weldy, Michelle

The Air Force minute sensor technology integration (MSTI-3) satellite's primary mission is to characterize Earth's atmospheric background clutter. MSTI-3 will use three cameras for data collection, a mid-wave infrared imager, a short wave infrared imager, and a visible imaging spectrometer. Mission science objectives call for the collection of over 2 million images within the one year mission life. In addition, operational constraints limit camera usage to four operations of twenty minutes per day, with no more than 10,000 data and calibrating images collected per day. To balance the operational constraints and science objectives, the mission planning team has designed a planning process to e event schedules and sensor operation timelines. Each set of constraints, including spacecraft performance capabilities, the camera filters, the geographical regions, and the spacecraft-Sun-Earth geometries of interest, and remote tracking station deconflictions has been accounted for in this methodology. To aid in this process, the mission planning team is building a series of tools from commercial off-the-shelf software. These include the mission manifest which builds a daily schedule of events, and the MSTI Scene Simulator which helps build geometrically correct scans. These tools provide an efficient, responsive, and highly flexible architecture that maximizes data collection while minimizing mission planning time.

The Radiation Monitoring Investigation of the Juno Mission will actively retrieve and analyze the noise signatures from penetrating radiation in the images of Juno's star cameras and science instruments at Jupiter. The investigation's objective is to profile Jupiter's >10-MeV electron environment in regions of the Jovian magnetosphere which today are still largely unexplored. This paper discusses the primary instruments on Juno which contribute to the investigation's data suite, the measurements of camera noise from penetrating particles, spectral sensitivities and measurement ranges of the instruments, calibrations performed prior to Juno's first science orbit, and how the measurements may be used to infer the external relativistic electron environment.

With the almost complete neglect of 19th century asteroid research by professional historians of science, it is scarcely surprising that great gaps exist in our knowledge of that important field. This paper focuses on issue of naming the first asteroid. This seemingly innocuous issue assumed great importance because many believed the object discovered by Giuseppe Piazzi at Palermo Observatory to be the eighth primary planet of the solar system.

The Mars Science Laboratory Robotic Arm (RA) is a key component for achieving the primary scientific goals of the mission. The RA supports sample acquisition by precisely positioning a scoop above loose regolith or accurately preloading a percussive drill on Martian rocks or rover-mounted organic check materials. It assists sample processing by orienting a sample processing unit called CHIMRA through a series of gravity-relative orientations and sample delivery by positioning the sample portion door above an instrument inlet or the observation tray. In addition the RA facilitates contact science by accurately positioning the dust removal tool, Alpha Particle X-Ray Spectrometer (APXS) and the Mars Hand Lens Imager (MAHLI) relative to surface targets. In order to fulfill these seemingly disparate science objectives the RA must satisfy a variety of accuracy and performance requirements. This paper describes the necessary arm requirement specification and the test campaign to demonstrate these requirements were satisfied.

Cullen, John J.

1995-01-01

This project was aimed at improved predictions of the effects of UVB and ozone depletion on marine primary productivity and carbon flux. A principal objective was to incorporate a new analytical description of photosynthesis as a function of UV and photosynthetically available radiation (Cullen et. al., Science 258:646) into a general oceanographic model. We made significant progress: new insights into the kinetics of photoinhibition were used in the analysis of experiments on Antarctic phytoplankton to generate a general model of UV-induced photoinhibition under the influence of ozone depletion and vertical mixing. The way has been paved for general models on a global scale.

Varley, Janet Penelope; Murphy, Clíona; Veale, Órlaith

2013-02-01

In Ireland, new science curricula were introduced at primary and early post-primary levels in 2003, in an effort to reverse declining interest and enrolment in science. This paper reports on a national study that explored first year post-primary students' experiences of and attitudes towards school science under these new curricula. Data were gathered from 366 pupils using survey and case study approaches. Findings revealed broadly positive attitudes towards post-primary school science, especially the experimental work that is at the heart of the new curriculum. However, it would appear that students were not conducting open-ended investigations or using information and communications technology [ICT] to any great extent; moreover, there was some evidence of traditional teaching methods being utilised. Pupils were highly critical of previous primary school science experiences, reporting a lack of `hands-on' activities, didactic methodologies and, for a significant minority, a paucity of any memorable primary science at all. Improvements in curricular implementation are proposed.

The Large Ultraviolet/Optical/Infrared Surveyor (LUVOIR) is one of four large mission concepts currently undergoing community study for consideration by the 2020 Astronomy and Astrophysics Decadal Survey. LUVOIR is being designed to pursue an ambitious program of exoplanetary discovery and characterization, cosmic origins astrophysics, and planetary science. The LUVOIR study team is investigating two large telescope apertures (9- and 15-meter primary mirror diameters) and a host of science instruments to carry out the primary mission goals. Many of the exoplanet, cosmic origins, and planetary science goals of LUVOIR require high-throughput, imaging spectroscopy at ultraviolet (100 - 400 nm) wavelengths. The LUVOIR Ultraviolet Multi-Object Spectrograph, LUMOS, is being designed to support all of the UV science requirements of LUVOIR, from exoplanet host star characterization to tomography of circumgalactic halos to water plumes on outer solar system satellites. LUMOS offers point source and multi-object spectroscopy across the UV bandpass, with multiple resolution modes to support different science goals. The instrument will provide low (R = 8,000 - 18,000) and medium (R = 30,000 - 65,000) resolution modes across the far-ultraviolet (FUV: 100 - 200 nm) and nearultraviolet (NUV: 200 - 400 nm) windows, and a very low resolution mode (R = 500) for spectroscopic investigations of extremely faint objects in the FUV. Imaging spectroscopy will be accomplished over a 3 × 1.6 arcminute field-of-view by employing holographically-ruled diffraction gratings to control optical aberrations, microshutter arrays (MSA) built on the heritage of the Near Infrared Spectrograph (NIRSpec) on the James Webb Space Telescope (JWST), advanced optical coatings for high-throughput in the FUV, and next generation large-format photon-counting detectors. The spectroscopic capabilities of LUMOS are augmented by an FUV imaging channel (100 - 200nm, 13 milliarcsecond angular resolution, 2 × 2 arcminute field-of-view) that will employ a complement of narrow- and medium-band filters. The instrument definition, design, and development are being carried out by an instrument study team led by the University of Colorado, Goddard Space Flight Center, and the LUVOIR Science and Technology Definition Team. LUMOS has recently completed a preliminary design in Goddard's Instrument Design Laboratory and is being incorporated into the working LUVOIR mission concept. In this proceeding, we describe the instrument requirements for LUMOS, the instrument design, and technology development recommendations to support the hardware required for LUMOS. We present an overview of LUMOS' observing modes and estimated performance curves for effective area, spectral resolution, and imaging performance. Example "LUMOS 100-hour Highlights" observing programs are presented to demonstrate the potential power of LUVOIR's ultraviolet spectroscopic capabilities.

Integrating the Teaching of Space Science, Planetary Exploration And Robotics In Elementary And Middle School with Mars Rover Models

The present aerospace engineering and science workforce is ageing. It is not clear that the US education system will produce enough qualified replacements to meet the need in the near future. Unfortunately, by the time many students get to high school, it is often too late to get them pointed toward an engineering or science career. Since some college programs require 6 units of high school mathematics for admission, students need to begin consciously preparing for a science or engineering curriculum as early as 6th or 7th grade. The challenge for educators is to convince elementary school students that science and engineering are both exciting, relevant and accessible career paths. This paper describes a program designed to help provide some excitement and relevance. It is based on the task of developing a mobile robot or "Rover" to explore the surface of Mars. There are two components to the program, a curriculum unit and a contest. The curriculum unit is structured as a 6-week planetary science unit for elementary school (grades 3-5). It can also be used as a curriculum unit, enrichment program or extracurricular activity in grades 6-8 by increasing the expected level of scientific sophistication in the mission design. The second component is a citywide competition to select the most outstanding models that is held annually at a local college or University. Primary (Grades 3-5) and middle school (Grades 6-8) students interested in science and engineering will design and build of a model of a Mars Rover to carry out a specific science mission on the surface of Mars. The students will build the models as part of a 6-week Fall semester classroom-learning or homework project on Mars. The students will be given design criteria for a rover, and be required to do basic research on Mars that will determine the operational objectives and structural features of their rover. This module may be used as part of a class studying general science, earth science, solar system astronomy or robotics or as a multi-disciplinary unit for a gifted and talented program. A written report on the science objectives and design features of the Rover is required. The program includes specific learning objectives in research skills, language arts (reading scientific literature, preparing a verbal presentation and writing a report), mathematics, science and engineering.The model will be mostly a mock-up, constructed at a minimal cost (estimated cost of less than 10-25) of mostly found objects and simple art supplies.

Jordanian Preservice Primary Teachers' Perceptions of Mentoring in Science Teaching

2015-03-01

Quality mentoring is fundamental to preservice teacher education because of its potential to help student and novice teachers develop the academic and pedagogical knowledge and skills germane to successful induction into the profession. This study focused on Jordanian preservice primary teachers' perceptions of their mentoring experiences as these pertain to science teaching. The Mentoring for Effective Primary Science Teaching instrument was administered to 147 senior preservice primary teachers in a university in Jordan. The results indicated that the greater majority of participants did not experience effective mentoring toward creating a supportive and reflexive environment that would bolster their confidence in teaching science; further their understanding of primary science curriculum, and associated aims and school policies; help with developing their pedagogical knowledge; and/or furnish them with specific and targeted feedback and guidance to help improve their science teaching. Substantially more participants indicated that their mentors modeled what they perceived to be effective science teaching. The study argues for the need for science-specific mentoring for preservice primary teachers, and suggests a possible pathway for achieving such a model starting with those in-service primary teachers-much like those identified by participants in the present study-who are already effective in their science teaching.

`You Actually Feel like You're Actually Doing Some Science': Primary Students' Perspectives of Their Involvement in the MyScience Initiative

MyScience is a primary science education initiative in which being in a community of practice (CoP) is integral to the learning process. Stakeholder groups—primary teachers, primary students and scientist mentors—interact around the CoP domainof investigating scientifically and learn from each other through participation. This paper is the fifth in a series and reports 27 year 5/6 students' (from three schools) perceptions of how their views were influenced through their involvement in a MyScience CoP. Semi-structured interviews, guided by a phenomenographic framework, were the substantive data source. Primary students' perceptions about science, science learning and science teaching were analysed using attributes associated with both communities of practice and the nature of science. Findings reveal that students' perceptions of what it means to be doing science' were transformed through their participation and students were able to identify some of the contributing factors. Where appropriate, students' views were compared with the published views of their participating scientist mentors and teachers from earlier papers. Implications for science teaching and learning in primary school community of practice settings are discussed.

Researching Primary Teachers' Professional Agency: Employing Interactive Ethnography to Overcome Reluctance to Teach Science

NASA Astrophysics Data System (ADS)

Martin, Jenny

2017-09-01

This paper provides a report of a case study on the professional agency of an experienced early years teacher, Sarah, who successfully embedded a chemical science program of teaching-learning for her students aged between 6 and 8. Interactive ethnography informs the research design, and discursive psychology provides the tools for the analysis of Sarah's speech acts for her positioning as a responsible agent. Reframing the problem of primary teacher reluctance to teach science in terms of primary teachers' professional agency using discursive psychology, this ontological study provides new insight into issues related to the provision of science education in primary schools and asks: How do primary teachers position themselves and others in relation to science curriculum and education? The research calls for research methodologies and reform efforts in primary science that are better grounded in the local moral orders of primary schools.

Training of physicians for the twenty-first century: role of the basic sciences.

PubMed

Grande, Joseph P

2009-09-01

Rapid changes in the healthcare environment and public dissatisfaction with the cost and quality of medical care have prompted a critical analysis of how physicians are trained in the United States. Accrediting agencies have catalyzed a transformation from a process based to a competency-based curriculum, both at the undergraduate and the graduate levels. The objective of this overview is to determine how these changes are likely to alter the role of basic science in medical education. Policy statements related to basic science education from the National Board of Medical Examiners (NBME), the Accreditation Council for Graduate Medical Education (ACGME), American Board of Medical Specialties (ABMS), and the Federation of State Medical Boards (FSMB) were reviewed and assessed for common themes. Three primary roles for the basic sciences in medical education are proposed: (1) basic science to support the development of clinical reasoning skills; (2) basic science to support a critical analysis of medical and surgical interventions ("evidence-based medicine"); and (3) basic and translational science to support analysis of processes to improve healthcare ("science of healthcare delivery"). With these roles in mind, several methods to incorporate basic sciences into the curriculum are suggested.

Energy is a crosscutting concept in science and features prominently in national science education documents. In the Next Generation Science Standards, the primary conceptual learning goal is for learners to conserve energy as they track the transfers and transformations of energy within, into, or out of the system of interest in complex physical processes. As part of tracking energy transfers among objects, learners should (i) distinguish energy from matter, including recognizing that energy flow does not uniformly align with the movement of matter, and should (ii) identify specific mechanisms by which energy is transferred among objects, such as mechanical work and thermal conduction. As part of tracking energy transformations within objects, learners should (iii) associate specific forms with specific models and indicators (e.g., kinetic energy with speed and/or coordinated motion of molecules, thermal energy with random molecular motion and/or temperature) and (iv) identify specific mechanisms by which energy is converted from one form to another, such as incandescence and metabolism. Eventually, we may hope for learners to be able to optimize systems to maximize some energy transfers and transformations and minimize others, subject to constraints based in both imputed mechanism (e.g., objects must have motion energy in order for gravitational energy to change) and the second law of thermodynamics (e.g., heating is irreversible). We hypothesize that a subsequent goal of energy learning—innovating to meet socially relevant needs—depends crucially on the extent to which these goals have been met.

Between October 2000 and June 2001, an Agency-wide planning, effort was organized by elements of NASA Goddard Space Flight Center (GSFC) to define future research and technology development activities. This planning effort was conducted at the request of the Associate Administrator of the Office of Earth Science (Code Y), Dr. Ghassem Asrar, at NASA Headquarters (HQ). The primary points of contact were Dr. Mary Cleave, Deputy Associate Administrator for Advanced Planning at NASA HQ (Headquarters) and Dr. Charles McClain of the Office of Global Carbon Studies (Code 970.2) at GSFC. During this period, GSFC hosted three workshops to define the science requirements and objectives, the observational and modeling requirements to meet the science objectives, the technology development requirements, and a cost plan for both the science program and new flight projects that will be needed for new observations beyond the present or currently planned. The plan definition process was very intensive as HQ required the final presentation package by mid-June 2001. This deadline was met and the recommendations were ultimately refined and folded into a broader program plan, which also included climate modeling, aerosol observations, and science computing technology development, for contributing to the President's Climate Change Research Initiative. This technical memorandum outlines the process and recommendations made for cross-cutting carbon cycle research as presented in June. A separate NASA document outlines the budget profiles or cost analyses conducted as part of the planning effort.

The Palomar Transient Factory (PTF) Orion project is one of the experiments within the broader PTF survey, a systematic automated exploration of the sky for optical transients. Taking advantage of the wide (3fdg5 × 2fdg3) field of view available using the PTF camera installed at the Palomar 48 inch telescope, 40 nights were dedicated in 2009 December to 2010 January to perform continuous high-cadence differential photometry on a single field containing the young (7-10 Myr) 25 Ori association. Little is known empirically about the formation of planets at these young ages, and the primary motivation for the project is to search for planets around young stars in this region. The unique data set also provides for much ancillary science. In this first paper, we describe the survey and the data reduction pipeline, and present some initial results from an inspection of the most clearly varying stars relating to two of the ancillary science objectives: detection of eclipsing binaries and young stellar objects. We find 82 new eclipsing binary systems, 9 of which are good candidate 25 Ori or Orion OB1a association members. Of these, two are potential young W UMa type systems. We report on the possible low-mass (M-dwarf primary) eclipsing systems in the sample, which include six of the candidate young systems. Forty-five of the binary systems are close (mainly contact) systems, and one of these shows an orbital period among the shortest known for W UMa binaries, at 0.2156509 ± 0.0000071 days, with flat-bottomed primary eclipses, and a derived distance that appears consistent with membership in the general Orion association. One of the candidate young systems presents an unusual light curve, perhaps representing a semi-detached binary system with an inflated low-mass primary or a star with a warped disk, and may represent an additional young Orion member. Finally, we identify 14 probable new classical T-Tauri stars in our data, along with one previously known (CVSO 35) and one previously reported as a candidate weak-line T-Tauri star (SDSS J052700.12+010136.8).

O'Meara, John; LUVOIR Science and Technology Definition Team

2018-01-01

LUVOIR is one of four large mission concepts for which the NASA Astrophysics Division has commissioned studies by Science and Technology Definition Teams (STDTs) drawn from the astronomical community. We are currently developing two architectures: Architecture A with a 15.1 meter segmented primary mirror, and Architecture B with a 9.2 meter segmented primary mirror. Our focus in this presentation is the Architecture A LUVOIR. LUVOIR will operate at the Sun-Earth L2 point. It will be designed to support a broad range of astrophysics and exoplanet studies. The initial instruments developed for LUVOIR Architecture A include 1) a high-performance optical/NIR coronagraph with imaging and spectroscopic capability, 2) a UV imager and spectrograph with high spectral resolution and multi-object capability, 3) a high-definition wide-field optical/NIR camera, and 4) a high resolution UV/optical spectropolarimeter. LUVOIR will be designed for extreme stability to support unprecedented spatial resolution and coronagraphy. It is intended to be a long-lifetime facility that is both serviceable, upgradable, and primarily driven by guest observer science programs. In this presentation, we will describe the observatory, its instruments, and survey the transformative science LUVOIR can accomplish.

Introducing Pre-university Students to Primary Scientific Literature Through Argumentation Analysis

NASA Astrophysics Data System (ADS)

Koeneman, Marcel; Goedhart, Martin; Ossevoort, Miriam

2013-10-01

Primary scientific literature is one of the most important means of communication in science, written for peers in the scientific community. Primary literature provides an authentic context for showing students how scientists support their claims. Several teaching strategies have been proposed using (adapted) scientific publications, some for secondary education, but none of these strategies focused specifically on scientific argumentation. The purpose of this study is to evaluate a strategy for teaching pre-university students to read unadapted primary scientific literature, translated into students' native language, based on a new argumentation analysis framework. This framework encompasses seven types of argumentative elements: motive, objective, main conclusion, implication, support, counterargument and refutation. During the intervention, students studied two research articles. We monitored students' reading comprehension and their opinion on the articles and activities. After the intervention, we measured students' ability to identify the argumentative elements in a third unadapted and translated research article. The presented framework enabled students to analyse the article by identifying the motive, objective, main conclusion and implication and part of the supports. Students stated that they found these activities useful. Most students understood the text on paragraph level and were able to read the article with some help for its vocabulary. We suggest that primary scientific literature has the potential to show students important aspects of the scientific process and to learn scientific vocabulary in an authentic context.

Teachers' perceptions on primary science teaching

NASA Astrophysics Data System (ADS)

Kijkuakul, Sirinapa

2018-01-01

This qualitative research aimed to review what primary teachers think about how to teach science in rural school contexts. Three primary schools in Thailand were purposively chosen for this study. Eleven primary science teachers of these schools were the research participants. Questionnaires, interviews, and observations were implemented to reveal the primary school teachers' educational backgrounds, science teaching context, and need for self-driven professional development. Content and discourse analysis indicated that the non-science educational background and the science teaching context implied a need for self-driven professional development. The non-science educational background teachers were generally unfamiliar with the current national science curriculum, and that they would not be comfortable when the researcher observed their science teaching practice. They also believed that experimentation was the only one strategy for teaching science, and that the priority for their teaching support was teaching media rather than their understanding of scientific concepts or teaching strategies. As implication of this research, subsequent developments on science teacher profession in rural context, therefore, need to promote teachers' understandings of nature of science and technological and pedagogical content knowledge. In addition, they should be challenged to practice on critically participatory action research for academic growth and professional learning community.

The Habitable Exoplanet Imaging Mission (HabEx) concept has been designed to enable an extensive suite of science, broadly put under the rubric of General Astrophysics, in addition to its exoplanet direct imaging science. General astrophysics directly addresses multiple NASA programmatic branches, and HabEx will enable investigations ranging from cosmology, to galaxy evolution, to stellar population studies, to exoplanet transit spectroscopy, to Solar System studies. This poster briefly describes one of the two primary HabEx General Astrophysics instruments, the HabEx Workhorse Camera (HWC). HWC will be a dual-detector UV-to-near-IR imager and multi-object grism spectrometer with a microshutter array and a moderate (3' x 3') field-of-view. We detail some of the key science we expect HWC to undertake, emphasizing unique capabilities enabled by a large-aperture, highly stable space-borne platform at these wavelengths.

In addition to the discovery and characterization of exoplanets, the coronagraph instrument (CGI) on WFIRST has the potential for ground-breaking discoveries in other fields through the Guest Observer (GO) program. 25% of the observing time in the primary mission will be made available to the GO community, and GO science with the CGI spans a broad range of scientific applications. These include imaging of binary and multiple asteroids and Kuiper Belt objects, the circumstellar environments of evolved giants and supergiants, debris disks around young stars, and the circumnuclear regions of active galactic nuclei. In this poster we summarize some of the key compelling science gains that can be pursued with the GO program and present preliminary analyses of the technical gains that the CGI will be able to offer over other contemporary coronagraphs, including those on JWST and ground-based observatories.

Stutzman, Warren L. (Editor); Brown, Gary S. (Editor)

1991-01-01

The primary objective of the Large Space Antenna (LSA) Science Panel was to evaluate the science benefits that can be realized with a 25-meter class antenna in a microwave/millimeter wave remote sensing system in geostationary orbit. The panel concluded that a 25-meter or larger antenna in geostationary orbit can serve significant passive remote sensing needs in the 10 to 60 GHz frequency range, including measurements of precipitation, water vapor, atmospheric temperature profile, ocean surface wind speed, oceanic cloud liquid water content, and snow cover. In addition, cloud base height, atmospheric wind profile, and ocean currents can potentially be measured using active sensors with the 25-meter antenna. Other environmental parameters, particularly those that do not require high temporal resolution, are better served by low Earth orbit based sensors.

"Efforts to broaden students' aspirations, particularly in relation to STEM, need to begin in primary school." Kings College London "Aspires" Research Project 2013 From my outreach activity I have learnt that primary teachers could feel under pressure when faced with delivering the science curriculum. The teachers could be lacking confidence in their subject knowledge, lacking the equipment needed to deliver practical science or lacking enthusiasm for the subject. In addition, English and Mathematics were the subjects that were externally tested and reported to the authorities and so some teachers felt that time for science was being marginalised to ensure the best results in the externally assessed subjects. In my work with The Ogden Trust Primary Science team I have been involved in developing a range of strategies to address some of the issues outlined above. • CPD (Teacher Training) Programme We have provided free training to improve teachers knowledge and understanding of key physics concepts to GCSE standard and a practical workshop consisting of ten investigations, extension and challenge tasks. The teachers each receive a book of lesson plans and a resource box containing a class set of the equipment required. The four year programme covers Forces Light and Sound Electricity Earth & Space • "Phiz Labs" Funding from The Ogden Trust has allowed us to set up science laboratories within primary schools. The pupils have lab coats, goggles and access to a range of equipment that allows them to participate in more practical science activity and open-ended investigative work. My Phiz Lab is in the secondary school where I teach physics and practical workshops for primary pupils and teachers are held there on a regular basis. • Enrichment In order to enthuse and challenge the primary pupils a variety of enrichment activities take place. These include "Physics of Go-Karts" and "Particle Physics for Primary" workshops, competitions and regional Science Fairs held at Universities. Stargazing evenings and Family Learning Nights where parents join their children to learn about science together are very popular. • Sixth Form Science Ambassadors A-level Physics students (age17-18) are trained as STEM Ambassadors to run after school science clubs for primary schools. I have worked with the British Science Association to develop this scheme and my students have received Gold CREST Awards for their science communication skills. This year, in conjunction with the Royal Institution, we have introduced "Maths for Physics Masterclasses" for gifted and talented primary pupils. Sixth form Space Ambassadors also train their younger peers to use the Bradford University Robotic Space Telescope to take images of planets and stars and to analyse the images. These schemes benefit the primary pupils, the sixth form students who gain invaluable teamwork and science communication skills and the primary teachers who attend these sessions. Initial evaluations have shown a greatly increased engagement in science in primary schools. Many of the schools involved have received the Primary Science Quality Mark.

The concept of landscape education at school level with respect to the directions of the science of landscape

NASA Astrophysics Data System (ADS)

Szczęsna, Joanna

2010-01-01

School education is both a starting point for the development of various scientific disciplines (school educates future researchers) and the result of science. The landscape research is conducted within many scientific disciplines and has a long tradition. Lanscape education, which is the result of a scientific dimension, is implemented in primary school under the nature subject. Primary school education is the only level at which the geographical contents are carried out on landscape. The landscape is of interest to many disciplines: geography, architecture, social sciences and the arts. In recent years, there were many studies which contained an overview of the main strands of the science of landscape, presented the differences in the meaning of the concept and objectives of individual research disciplines. These studies have become the ground for the characterization of the concept of landscape education implemented in Polish school and its evaluation in terms of scientific achievements. A review of educational purposes, the basic content of education and achievements of students, demonstrate the influence of multiple scientific disciplines in school landscape education. The most significant share of the course content are achievements of geography disciplines, particularly: physical geography, environmental protection and landscape ecology. Other scientific fields: literature, art, psychology, sociology, and architecture do not have any impact on the school landscape education or their impact remains marginal.

Studying the Surfaces of the Icy Galilean Satellites With JIMO

NASA Astrophysics Data System (ADS)

Prockter, L.; Schenk, P.; Pappalardo, R.

2003-12-01

The Geology subgroup of the Jupiter Icy Moons Orbiter (JIMO) Science Definition Team (SDT) has been working with colleagues within the planetary science community to determine the key outstanding science goals that could be met by the JIMO mission. Geological studies of the Galilean satellites will benefit from the spacecraft's long orbital periods around each satellite, lasting from one to several months. This mission plan allows us to select the optimal viewing conditions to complete global compositional and morphologic mapping at high resolution, and to target geologic features of key scientific interest at very high resolution. Community input to this planning process suggests two major science objectives, along with corresponding measurements proposed to meet them. Objective 1: Determine the origins of surface features and their implications for geological history and evolution. This encompasses investigations of magmatism (intrusion, extrusion, and diapirism), tectonism (isostatic compensation, and styles of faulting, flexure and folding), impact cratering (morphology and distribution), and gradation (erosion and deposition) processes (impact gardening, sputtering, mass wasting and frosts). Suggested measurements to meet this goal include (1) two dimensional global topographic mapping sufficient to discriminate features at a spatial scale of 10 m, and with better than or equal to 1 m relative vertical accuracy, (2) nested images of selected target areas at a range of resolutions down to the submeter pixel scale, (3) global (albedo) mapping at better than or equal to 10 m/pixel, and (4) multispectral global mapping in at least 3 colors at better than or equal to 100 m/pixel, with some subsets at better than 30 m/pixel. Objective 2. Identify and characterize potential landing sites for future missions. A primary component to the success of future landed missions is full characterization of potential sites in terms of their relative age, geological interest, and engineering safety. Measurement requirements suggested to meet this goal (in addition to the requirements of Objective 1) include the acquisition of super-high resolution images of selected target areas (with intermediate context imaging) down to 25 cm/pixel scale. The Geology subgroup passed these recommendations to the full JIMO Science Definition Team, to be incorporated into the final science recommendations for the JIMO mission.

How CubeSats contribute to Science and Technology in Astronomy and Astrophysics

NASA Astrophysics Data System (ADS)

Cahoy, Kerri Lynn; Douglas, Ewan; Carlton, Ashley; Clark, James; Haughwout, Christian

2017-01-01

CubeSats are nanosatellites, spacecraft typically the size of a shoebox or backpack. CubeSats are made up of one or more 10 cm x 10 cm x 10 cm units weighing 1.33 kg (each cube is called a “U”). CubeSats benefit from relatively easy and inexpensive access to space because they are designed to slide into fully enclosed spring-loaded deployer pods before being attached as an auxiliary payload to a larger vehicle, without adding risk to the vehicle or its primary payload(s). Even though CubeSats have inherent resource and aperture limitations due to their small size, over the past fifteen years, researchers and engineers have miniaturized components and subsystems, greatly increasing the capabilities of CubeSats. We discuss how state of the art CubeSats can address both science objectives and technology objectives in Astronomy and Astrophysics. CubeSats can contribute toward science objectives such as cosmic dawn, galactic evolution, stellar evolution, extrasolar planets and interstellar exploration.CubeSats can contribute to understanding how key technologies for larger missions, like detectors, microelectromechanical systems, and integrated optical elements, can not only survive launch and operational environments (which can often be simulated on the ground), but also meet performance specifications over long periods of time in environments that are harder to simulate properly, such as ionizing radiation, the plasma environment, spacecraft charging, and microgravity. CubeSats can also contribute to both science and technology advancements as multi-element space-based platforms that coordinate distributed measurements and use formation flying and large separation baselines to counter their restricted individual apertures.

An astrometric facility for planetary detection on the space station

NASA Technical Reports Server (NTRS)

Nishioka, Kenji; Scargle, Jeffrey D.; Givens, John J.

1987-01-01

An Astrometric Telescope Facility (ATF) for planetary detection is being studied as a potential space station initial operating capability payload. The primary science objective of this mission is the detection and study of planetary systems around other stars. In addition, the facility will be capable of other astrometric measurements such as stellar motions of other galaxies and highly precise direct measurement of stellar distance within the Milky Way Galaxy. The results of a recently completed ATF preliminary systems definition study are summarized. Results of this study indicate that the preliminary concept for the facility is fully capable of meeting the science objective without the development of any new technologies. A simple straightforward operations approach was developed for the ATF. A real-time facility control is not normally required, but does maintain a near real-time ground monitoring capability for the facility and science data stream on a full-time basis. Facility observational sequences are normally loaded once a week. In addition, the preliminary system is designed to be fail-safe and single-fault tolerant. Routine interactions by the space station crew with the ATF will not be necessary, but onboard controls are provided for crew override as required for emergencies and maintenance.

2011-01-01

NASA's MAVEN mission (to be launched in late 2013) is the first mission to Mars devoted to sampling all of the upper atmosphere neutral and plasma environments, including the well-mixed atmosphere, the exosphere, ionosphere, outer magnetosphere and near-Mars solar wind. It will fill in some measurement gaps remaining from the successful Mars Global Surveyor and the on-going Mars Express missions. The primary science objectives of MAVEN are: 1. Provide a comprehensive picture of the present state of the upper atmosphere and ionosphere of Mars; 2. Understand the processes controlling the present state; and 3. Determine how loss of volatiles to outer space in the present epoch varies with changing solar condition - EUY, solar wind and interplanetary magnetic field measurements will provide the varying solar energy inputs into the system. Knowing how these processes respond to the Sun's energy inputs in the current epoch will provide a framework for projecting atmospheric processes back in time to profile MARS' atmospheric evolution and to explore "where the water went", A description will be given of the science objectives, the instruments, and the current status of the project, emphasizing the value of having collaborations between the MAVEN project and the Mars upper atmosphere science community.

Patients’ perspectives on the medical primary–secondary care interface: systematic review and synthesis of qualitative research

2015-01-01

Objectives To synthesise the published literature on the patient experience of the medical primary–secondary care interface and to determine priorities for future work in this field aimed at improving clinical outcomes. Design Systematic review and metaethnographic synthesis of primary studies that used qualitative methods to explore patients’ perspectives of the medical primary–secondary care interface. Setting International primary–secondary care interface. Data sources EMBASE, MEDLINE, CINAHL Plus with Full text, PsycINFO, Psychology and Behavioural Sciences Collection, Health Business Elite, Biomedica Reference Collection: Comprehensive Library, Information Science & Technology Abstracts, eBook Collection, Web of Science Core Collection: Citation Indexes and Social Sciences Citation Index, and grey literature. Eligibility criteria for selecting studies Studies were eligible for inclusion if they were full research papers employing qualitative methodology to explore patients’ perspectives of the medical primary–secondary care interface. Review methods The 7-step metaethnographic approach described by Noblit and Hare, which involves cross-interpretation between studies while preserving the context of the primary data. Results The search identified 690 articles, of which 39 were selected for full-text review. 20 articles were included in the systematic review that encompassed a total of 689 patients from 10 countries. 4 important areas specific to the primary–secondary care interface from the patients’ perspective emerged: barriers to care, communication, coordination, and ‘relationships and personal value’. Conclusions and implications of key findings Patients should be the focus of any transfer of care between primary and secondary systems. From their perspective, areas for improvement may be classified into four domains that should usefully guide future work aimed at improving quality at this important interface.

Designing Science Learning in the First Years of Schooling. An intervention study with sequenced learning material on the topic of `floating and sinking'

NASA Astrophysics Data System (ADS)

Leuchter, Miriam; Saalbach, Henrik; Hardy, Ilonca

2014-07-01

Research on learning and instruction of science has shown that learning environments applied in preschool and primary school rarely makes use of structured learning materials in problem-based environments although these are decisive quality features for promoting conceptual change and scientific reasoning within early science learning. We thus developed and implemented a science learning environment for children in the first years of schooling which contains structured learning materials with the goal of supporting conceptual change concerning the understanding of the floating and sinking of objects and fostering students' scientific reasoning skills. In the present implementation study, we aim to provide a best-practice example of early science learning. The study was conducted with a sample of 15 classes of the first years of schooling and a total of 244 children. Tests were constructed to measure children's conceptual understanding before and after the implementation. Our results reveal a decrease in children's misconceptions from pretest to posttest. After the curriculum, the children were able to produce significantly more correct predictions about the sinking or floating of objects than before the curriculum and also relative to a control group. Moreover, due to the intervention, the explanations given for their predictions implied a more elaborated concept of material kinds. All in all, a well-structured curriculum promoting comparison and scientific reasoning by means of inquiry learning was shown to support children's conceptual change.

Final Report Scalable Analysis Methods and In Situ Infrastructure for Extreme Scale Knowledge Discovery

DOE Office of Scientific and Technical Information (OSTI.GOV)

O'Leary, Patrick

The primary challenge motivating this project is the widening gap between the ability to compute information and to store it for subsequent analysis. This gap adversely impacts science code teams, who can perform analysis only on a small fraction of the data they calculate, resulting in the substantial likelihood of lost or missed science, when results are computed but not analyzed. Our approach is to perform as much analysis or visualization processing on data while it is still resident in memory, which is known as in situ processing. The idea in situ processing was not new at the time ofmore » the start of this effort in 2014, but efforts in that space were largely ad hoc, and there was no concerted effort within the research community that aimed to foster production-quality software tools suitable for use by Department of Energy (DOE) science projects. Our objective was to produce and enable the use of production-quality in situ methods and infrastructure, at scale, on DOE high-performance computing (HPC) facilities, though we expected to have an impact beyond DOE due to the widespread nature of the challenges, which affect virtually all large-scale computational science efforts. To achieve this objective, we engaged in software technology research and development (R&D), in close partnerships with DOE science code teams, to produce software technologies that were shown to run efficiently at scale on DOE HPC platforms.« less

The Gravity Recovery and Interior Laboratory (GRAIL), a dual-spacecraft, gravity-mapping mission that is a component of NASA's Discovery Program, has successfully concluded its Primary and Extended Missions, and is currently in the science analysis phase. In order to safely navigate the dual spacecraft at an average altitude of 22.5 km above the lunar surface during the Extended Mission phase in the fall of 2012, and to derive the greatest information from the full mission data set, the focus had been on the production of gravitational fields with the highest-possible resolution. Spherical harmonic models of the Moon's gravitational field, produced by separate software systems at the Goddard Space Flight Center and the Jet Propulsion Laboratory, now include observations from both the Primary and Extended Missions. The highest-resolution models to date are to degree and order 900, corresponding to a spatial block size of 6 km, and are ideally suited to study the structure of the Moon's crust in extraordinary detail. GRAIL has achieved all measurement objectives for the Primary Mission, enabling all science investigations to be addressed. One of these investigations is to study the lunar hemispherical asymmetry, i.e., the difference between the nearside and farside. In this study we explore the nearside and farside mantle by isolating the long-wavelength gravity field. We accomplish this objective by removing plausible short-wavelength contributions from the crust that were based on the full resolution of high-degree and -order models, and by considering constraints from crustal compositions and volumes of mare basalt deposits. We localize the power spectral contributions of the nearside and farside to constrain lateral density variations, such as those associated with melting from the source regions of the mare basalts.

Technical Report Series on Global Modeling and Data Assimilation. Volume 40; Soil Moisture Active Passive (SMAP) Project Assessment Report for the Beta-Release L4_SM Data Product

2015-01-01

During the post-launch SMAP calibration and validation (Cal/Val) phase there are two objectives for each science data product team: 1) calibrate, verify, and improve the performance of the science algorithm, and 2) validate the accuracy of the science data product as specified in the science requirements and according to the Cal/Val schedule. This report provides an assessment of the SMAP Level 4 Surface and Root Zone Soil Moisture Passive (L4_SM) product specifically for the product's public beta release scheduled for 30 October 2015. The primary objective of the beta release is to allow users to familiarize themselves with the data product before the validated product becomes available. The beta release also allows users to conduct their own assessment of the data and to provide feedback to the L4_SM science data product team. The assessment of the L4_SM data product includes comparisons of SMAP L4_SM soil moisture estimates with in situ soil moisture observations from core validation sites and sparse networks. The assessment further includes a global evaluation of the internal diagnostics from the ensemble-based data assimilation system that is used to generate the L4_SM product. This evaluation focuses on the statistics of the observation-minus-forecast (O-F) residuals and the analysis increments. Together, the core validation site comparisons and the statistics of the assimilation diagnostics are considered primary validation methodologies for the L4_SM product. Comparisons against in situ measurements from regional-scale sparse networks are considered a secondary validation methodology because such in situ measurements are subject to upscaling errors from the point-scale to the grid cell scale of the data product. Based on the limited set of core validation sites, the assessment presented here meets the criteria established by the Committee on Earth Observing Satellites for Stage 1 validation and supports the beta release of the data. The validation against sparse network measurements and the evaluation of the assimilation diagnostics address Stage 2 validation criteria by expanding the assessment to regional and global scales.

Satellite Ocean Color Sensor Design Concepts and Performance Requirements

NASA Technical Reports Server (NTRS)

McClain, Charles R.; Meister, Gerhard; Monosmith, Bryan

2014-01-01

In late 1978, the National Aeronautics and Space Administration (NASA) launched the Nimbus-7 satellite with the Coastal Zone Color Scanner (CZCS) and several other sensors, all of which provided major advances in Earth remote sensing. The inspiration for the CZCS is usually attributed to an article in Science by Clarke et al. who demonstrated that large changes in open ocean spectral reflectance are correlated to chlorophyll-a concentrations. Chlorophyll-a is the primary photosynthetic pigment in green plants (marine and terrestrial) and is used in estimating primary production, i.e., the amount of carbon fixed into organic matter during photosynthesis. Thus, accurate estimates of global and regional primary production are key to studies of the earth's carbon cycle. Because the investigators used an airborne radiometer, they were able to demonstrate the increased radiance contribution of the atmosphere with altitude that would be a major issue for spaceborne measurements. Since 1978, there has been much progress in satellite ocean color remote sensing such that the technique is well established and is used for climate change science and routine operational environmental monitoring. Also, the science objectives and accompanying methodologies have expanded and evolved through a succession of global missions, e.g., the Ocean Color and Temperature Sensor (OCTS), the Seaviewing Wide Field-of-view Sensor (SeaWiFS), the Moderate Resolution Imaging Spectroradiometer (MODIS), the Medium Resolution Imaging Spectrometer (MERIS), and the Global Imager (GLI). With each advance in science objectives, new and more stringent requirements for sensor capabilities (e.g., spectral coverage) and performance (e.g., signal-to-noise ratio, SNR) are established. The CZCS had four bands for chlorophyll and aerosol corrections. The Ocean Color Imager (OCI) recommended for the NASA Pre-Aerosol, Cloud, and Ocean Ecosystems (PACE) mission includes 5 nanometers hyperspectral coverage from 350 to 800 nanometers with three additional discrete near infrared (NIR) and shortwave infrared (SWIR) ocean aerosol correction bands. Also, to avoid drift in sensor sensitivity from being interpreted as environmental change, climate change research requires rigorous monitoring of sensor stability. For SeaWiFS, monthly lunar imaging accurately tracked stability at an accuracy of approximately 0.1% that allowed the data to be used for climate studies [2]. It is now acknowledged by the international community that future missions and sensor designs need to accommodate lunar calibrations. An overview of ocean color remote sensing and a review of the progress made in ocean color remote sensing and the variety of research applications derived from global satellite ocean color data are provided. The purpose of this chapter is to discuss the design options for ocean color satellite radiometers, performance and testing criteria, and sensor components (optics, detectors, electronics, etc.) that must be integrated into an instrument concept. These ultimately dictate the quality and quantity of data that can be delivered as a trade against mission cost. Historically, science and sensor technology have advanced in a "leap-frog" manner in that sensor design requirements for a mission are defined many years before a sensor is launched and by the end of the mission, perhaps 15-20 years later, science applications and requirements are well beyond the capabilities of the sensor. Section 3 provides a summary of historical mission science objectives and sensor requirements. This progression is expected to continue in the future as long as sensor costs can be constrained to affordable levels and still allow the incorporation of new technologies without incurring unacceptable risk to mission success. The IOCCG Report Number 13 discusses future ocean biology mission Level-1 requirements in depth.

Teaching physics using project-based engineering curriculum with a theme of alternative energy

NASA Astrophysics Data System (ADS)

Tasior, Bryan

The Next Generation Science Standards (NGSS) provide a new set of science standards that, if adopted, shift the focus from content knowledge-based to skill-based education. Students will be expected to use science to investigate the natural world and solve problems using the engineering design process. The world also is facing an impending crisis related to climate, energy supply and use, and alternative energy development. Education has an opportunity to help provide the much needed paradigm shift from our current methods of providing the energy needs of society. The purpose of this research was to measure the effectiveness of a unit that accomplishes the following objectives: uses project-based learning to teach the engineering process and standards of the NGSS, addresses required content expectations of energy and electricity from the HSCE's, and provides students with scientific evidence behind issues (both environmental and social/economic) relating to the energy crisis and current dependence of fossil fuels as our primary energy source. The results of the research indicate that a physics unit can be designed to accomplish these objectives. The unit that was designed, implemented and reported here also shows that it was highly effective at improving students' science content knowledge, implementing the engineering design standards of the NGSS, while raising awareness, knowledge and motivations relating to climate and the energy crisis.

Promoting children's agency and communication skills in an informal science program

The Partnerships for Informal Science Education in the Community (PISEC) program at the University of Colorado Boulder brings together university and community institutions to create an environment where K-12 students join with university educators to engage in inquiry-based scientific practices after school. In our original framing, these afterschool activities were developed to reinforce the traditional learning goals of the classroom, including mastering scientific content, skills and processes. Recently, the primary focus of the PISEC curriculum has been shifted towards the development of students' scientific identity, an explicit objective of informal learning environments. The new curriculum offers students more activity choices, affords opportunities for scientific drawings and descriptions, and provides incentive for students to design their own experiments. We have analyzed student science notebooks from both old and new curricula and find that with the redesigned curriculum, students exhibit increased agency and more instances of scientific communication while still demonstrating substantial content learning gains.

Tethered Formation Configurations: Meeting the Scientific Objectives of Large Aperture and Interferometric Science

Farley, Rodger E.; Quinn, David A.; Brodeur, Stephen J. (Technical Monitor)

2001-01-01

With the success of the Hubble Space Telescope, it has become apparent that new frontiers of science and discovery are made every time an improvement in imaging resolution is made. For the HST working primarily in the visible and near-visible spectrum, this meant designing, building, and launching a primary mirror approximately three meters in diameter. Conventional thinking tells us that accomplishing a comparable improvement in resolution at longer wavelengths for Earth and Space Science applications requires a corresponding increase in the size of the primary mirror. For wavelengths in the sub-millimeter range, a very large telescope with an effective aperture in excess of one kilometer in diameter would be needed to obtain high quality angular resolution. Realistically a single aperture this large is practically impossible. Fortunately such large apertures can be constructed synthetically. Possibly as few as three 34 meter diameter mirrors flying in precision formation could be used to collect light at these longer wavelengths permitting not only very large virtual aperture science to be carried out, but high-resolution interferometry as well. To ensure the longest possible mission duration, a system of tethered spacecraft will be needed to mitigate the need for a great deal of propellant. A spin-stabilized, tethered formation will likely meet these requirements. Several configurations have been proposed which possibly meet the needs of the Space Science community. This paper discusses two of them, weighing the relative pros and cons of each concept. The ultimate goal being to settle on a configuration which combines the best features of structure, tethers, and formation flying to meet the ambitious requirements necessary to make future large synthetic aperture and interferometric science missions successful.

Chell, Kaitlin

2009-11-01

AGU and 17 other scientific organizations sent an open letter to the U.S. Senate on 21 October reminding senators of the scientific consensus on anthropogenic climate change. The letter was sent 1 week before the Senate Committee on Environment and Public Works began a series of hearings on climate change legislation, the Clean Energy Jobs and American Power Act (Senate bill 1733). The letter states, “Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver. These conclusions are based on multiple independent lines of evidence, and contrary assertions are inconsistent with an objective assessment of the vast body of peer-reviewed science.”

The Physicists in Primary Schools (PIPS) project is a joint venture initiated by the UK Women in Physics Group. A team from the University of Sheffield, with Engineering and Physical Sciences Research Council funding, has developed fun presentations and novel class activities using everyday articles for physicists to take into primary schools. The objectives are to instill enthusiasm in young children-including girls-through the enjoyment and excitement of physics, and support primary school teachers with a curriculum which includes many abstract concepts. All PIPS material is free to download from the Institute of Physics website (www.iop.org/pips), providing PowerPoint presentations and detailed explanations, as well as videos of the activities in classrooms. The topics are suitable for children age 4 to 11 years. There is interest in translating the presentations into other languages as there are few words on the slides and the material is likely valuable for older age groups. The presentations therefore have the potential to be useful worldwide.

Summary of the Science Performed Onboard the International Space Station within the United States Orbital Segment during Increments 16 and 17

NASA Technical Reports Server (NTRS)

Jules, Kenol; Istasse, Eric; Stenuit, Hilde; Murakami, Jeiji; Yoshizaki, Izumi; Johnson-Green, Perry

2008-01-01

With the launch of the STS-122 on February 7, 2008, which delivered the European Columbus science module and the upcoming STS-124 flight, which will deliver the Japanese Kibo science module in May 2008, the International Space Station will become truly International with Europe and Japan joining the United States of America and Russia to perform science on a continuous basis in a wide spectrum of science disciplines. The last science module, Kibo, of the United States Orbital Segment (USOS) will be mated to the station on time to celebrate its first decade in low Earth orbit in October 2008 (end of Increment 17), thus ushering in the second decade of the station with all the USOS science modules mated and performing science. The arrival of the Kibo science module will also mark continuous human presence on the station for eighty eight (88) months, and, with the addition of the ESA science module during the STS-122 flight, the USOS will be made up of four space agencies: CSA, ESA, JAXA and NASA, spanning three continents. With the additional partners coming onboard with different research needs, every effort is being made to coordinate science across the USOS segment in an integrated manner for the benefit of all parties. One of the objectives of this paper is to discuss the integrated manner in which science planning/replanning and prioritization during the execution phase of an increment is being done. The main focus, though, of this paper is to summarize and to discuss the science performed during Increments 16 and 17 (October 2007 to October 2008). The discussion will focus mainly on the primary objectives of each investigation and their associated hypotheses that were investigated during these two Increments. Also, preliminary science results will be discussed for each of the investigation as science results availability permit. Additionally, the paper will briefly touch on what the science complement for these two increments was and what was actually accomplished due to real time science implementation and constraints. Finally, the paper will briefly discuss the science research complements for the next three Increments: Increments 18 to 20, in order to preview how much science might be accomplished during these three upcoming Increments of the station next decade.

An in-depth study of a teacher engaged in an innovative primary science trial professional development project

NASA Astrophysics Data System (ADS)

Watters, James J.; Ginns, Ian S.

1997-03-01

The implementation of effective science programmes in primary schools is of continuing interest and concern for professional developers. As part of the Australian Academy of science's approach to creating an awareness of Primary Investigations, a project team trialed a series of satellite television broadcasts of lessons related to two units of the curriculum for Year 3 and 4 children in 48 participating schools. The professional development project entitled Simply Science, included a focused component for the respective classroom teachers, which was also conducted by satellite. This paper reports the involvement of a Year 4 teacher in the project and describes her professional growth. Already an experienced and confident teacher, no quantitative changes in science teaching self efficacy were detected. However, her pedagogical content knowledge and confidence to teach science in the concept areas of matter and energy were enhanced. Changes in the teacher's views about the co-operative learning strategies espoused by Primary Investigations were also evident. Implications for the design of professional development programmes for primary science teachers are discussed.

Mars Reconnaissance Orbiter Mission: Systems Engineering Challenges on the Mars Reconnaissance Orbiter Mission

Havens, Glen G.

2007-01-01

MRO project is a system of systems requiring system engineering team to architect, design, integrate, test, and operate these systems at each level of the project. The challenge of system engineering mission objectives into a single mission architecture that can be integrated tested, launched, and operated. Systems engineering must translate high-level requirements into integrated mission design. Systems engineering challenges were overcome utilizing a combination by creative designs built into MRO's flight and ground systems: a) Design of sophisticated spacecraft targeting and data management capabilities b) Establishment of a strong operations team organization; c) Implementation of robust operational processes; and d) Development of strategic ground tools. The MRO system has met the challenge of its driving requirements: a) MRO began its two-year primary science phase on November 7, 2006, and by July 2007, met it minimum requirement to collect 15 Tbits of data after only eight months of operations. Currently we have collected 22 Tbits. b) Based on current performance, mission data return could return 70 Tbits of data by the end of the primary science phase in 2008.

Primary teachers conducting inquiry projects: effects on attitudes towards teaching science and conducting inquiry

NASA Astrophysics Data System (ADS)

van Aalderen-Smeets, Sandra I.; Walma van der Molen, Juliette H.; van Hest, Erna G. W. C. M.; Poortman, Cindy

2017-01-01

This study used an experimental, pretest-posttest control group design to investigate whether participation in a large-scale inquiry project would improve primary teachers' attitudes towards teaching science and towards conducting inquiry. The inquiry project positively affected several elements of teachers' attitudes. Teachers felt less anxious about teaching science and felt less dependent on contextual factors compared to the control group. With regard to attitude towards conducting inquiry, teachers felt less anxious and more able to conduct an inquiry project. There were no effects on other attitude components, such as self-efficacy beliefs or relevance beliefs, or on self-reported science teaching behaviour. These results indicate that practitioner research may have a partially positive effect on teachers' attitudes, but that it may not be sufficient to fully change primary teachers' attitudes and their actual science teaching behaviour. In comparison, a previous study showed that attitude-focused professional development in science education has a more profound impact on primary teachers' attitudes and science teaching behaviour. In our view, future interventions aiming to stimulate science teaching should combine both approaches, an explicit focus on attitude change together with familiarisation with inquiry, in order to improve primary teachers' attitudes and classroom practices.

Measuring Primary Teachers' Attitudes Toward Teaching Science: Development of the Dimensions of Attitude Toward Science (DAS) Instrument

NASA Astrophysics Data System (ADS)

van Aalderen-Smeets, Sandra; Walma van der Molen, Juliette

2013-03-01

In this article, we present a valid and reliable instrument which measures the attitude of in-service and pre-service primary teachers toward teaching science, called the Dimensions of Attitude Toward Science (DAS) Instrument. Attention to the attitudes of primary teachers toward teaching science is of fundamental importance to the professionalization of these teachers in the field of primary science education. With the development of this instrument, we sought to fulfill the need for a statistically and theoretically valid and reliable instrument to measure pre-service and in-service teachers' attitudes. The DAS Instrument is based on a comprehensive theoretical framework for attitude toward (teaching) science. After pilot testing, the DAS was revised and subsequently validated using a large group of respondents (pre-service and in-service primary teachers) (N = 556). The theoretical underpinning of the DAS combined with the statistical data indicate that the DAS possesses good construct validity and that it proves to be a promising instrument that can be utilized for research purposes, and also as a teacher training and coaching tool. This instrument can therefore make a valuable contribution to progress within the field of science education.

Unintended Learning in Primary School Practical Science Lessons from Polanyi's Perspective of Intellectual Passion

NASA Astrophysics Data System (ADS)

Park, Jisun; Song, Jinwoong; Abrahams, Ian

2016-03-01

This study explored, from the perspective of intellectual passion developed by Michael Polanyi, the unintended learning that occurred in primary practical science lessons. We use the term `unintended' learning to distinguish it from `intended' learning that appears in teachers' learning objectives. Data were collected using video and audio recordings of a sample of twenty-four whole class practical science lessons, taught by five teachers, in Korean primary schools with 10- to 12-year-old students. In addition, video and audio recordings were made for each small group of students working together in order to capture their activities and intra-group discourse. Pre-lesson interviews with the teachers were undertaken and audio-recorded to ascertain their intended learning objectives. Selected key vignettes, including unintended learning, were analysed from the perspective of intellectual passion developed by Polanyi. What we found in this study is that unintended learning could occur when students got interested in something in the first place and could maintain their interest. In addition, students could get conceptual knowledge when they tried to connect their experience to their related prior knowledge. It was also found that the processes of intended learning and of unintended learning were different. Intended learning was characterized by having been planned by the teacher who then sought to generate students' interest in it. In contrast, unintended learning originated from students' spontaneous interest and curiosity as a result of unplanned opportunities. Whilst teachers' persuasive passion comes first in the process of intended learning, students' heuristic passion comes first in the process of unintended learning. Based on these findings, we argue that teachers need to be more aware that unintended learning, on the part of individual students, can occur during their lesson and to be able to better use this opportunity so that this unintended learning can be shared by the whole class. Furthermore, we argue that teachers' deliberate action and a more interactive classroom culture are necessary in order to allow students to develop, in addition to heuristic passion, persuasive passion towards their unintended learning.

Engaging with primary schools: Supporting the delivery of the new curriculum in evolution and inheritance.

PubMed

Kover, Paula X; Hogge, Emily S

2017-10-01

The official school regulator in England (OFSTED) recently reported that the delivery of science lessons has been significantly diminished in many primary schools. There is concern that the lack of good quality science in school can reduce the recruitment of young scientists, and the level of science literacy among the general public. We believe university scientists and undergraduate students can have a significant impact in the delivery of science in primary schools. However, a relatively small proportion of scientists engage with young children to improve curricular primary school science education. Here, we argue that long term engagement with primary schools can produce significant impact for the scientist's research, schools, and society. As an example, we describe our experience developing teaching materials for the topic of "Evolution and inheritance"; highlighting possible pitfalls and perceived benefits, in hope of encouraging and facilitating other scientists to engage with primary schools.

This paper draws on organizational science to reflect on why primary care research networks appear to be appropriate for primary care research and how their structures and processes can best enable the achievement of their aims.

Scalable Analysis Methods and In Situ Infrastructure for Extreme Scale Knowledge Discovery

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bethel, Wes

2016-07-24

The primary challenge motivating this team’s work is the widening gap between the ability to compute information and to store it for subsequent analysis. This gap adversely impacts science code teams, who are able to perform analysis only on a small fraction of the data they compute, resulting in the very real likelihood of lost or missed science, when results are computed but not analyzed. Our approach is to perform as much analysis or visualization processing on data while it is still resident in memory, an approach that is known as in situ processing. The idea in situ processing wasmore » not new at the time of the start of this effort in 2014, but efforts in that space were largely ad hoc, and there was no concerted effort within the research community that aimed to foster production-quality software tools suitable for use by DOE science projects. In large, our objective was produce and enable use of production-quality in situ methods and infrastructure, at scale, on DOE HPC facilities, though we expected to have impact beyond DOE due to the widespread nature of the challenges, which affect virtually all large-scale computational science efforts. To achieve that objective, we assembled a unique team of researchers consisting of representatives from DOE national laboratories, academia, and industry, and engaged in software technology R&D, as well as engaged in close partnerships with DOE science code teams, to produce software technologies that were shown to run effectively at scale on DOE HPC platforms.« less

Politicizing science: conceptions of politics in science and technology studies.

PubMed

Brown, Mark B

2015-02-01

This essay examines five ideal-typical conceptions of politics in science and technology studies. Rather than evaluating these conceptions with reference to a single standard, the essay shows how different conceptions of politics serve distinct purposes: normative critique, two approaches to empirical description, and two views of democracy. I discuss each conception of politics with respect to how well it fulfills its apparent primary purpose, as well as its implications for the purpose of studying a key issue in contemporary democratic societies: the politicization of science. In this respect, the essay goes beyond classifying different conceptions of politics and also recommends the fifth conception as especially conducive to understanding and shaping the processes whereby science becomes a site or object of political activity. The essay also employs several analytical distinctions to help clarify the differences among conceptions of politics: between science as 'political' (adjective) and science as a site of 'politics' (noun), between spatial-conceptions and activity-conceptions of politics, between latent conflicts and actual conflicts, and between politics and power. The essay also makes the methodological argument that the politics of science and technology is best studied with concepts and methods that facilitate dialogue between actors and analysts. The main goal, however, is not to defend a particular view of politics, but to promote conversation on the conceptions of politics that animate research in social studies of science and technology.

Students as 'catalysts' in the classroom: the impact of co-teaching between science student teachers and primary classroom teachers on children's enjoyment and learning of science

NASA Astrophysics Data System (ADS)

Murphy, Colette; Beggs, Jim; Carlisle, Karen; Greenwood, Julian

2004-08-01

This study is an investigation of the impact of collaborative teaching by student-teachers and classroom teachers on children's enjoyment and learning of science. The paper describes findings from a project in which undergraduate science specialist student-teachers were placed in primary schools where they 'co-taught' investigative science and technology with primary teachers. Almost six months after the student placement, a survey of children's attitudes to school science revealed that these children enjoyed science lessons more and showed fewer gender or age differences in their attitudes to science than children who had not been involved in the project. The authors discuss how this model of collaborative planning, teaching and evaluation can both enhance teacher education and improve children's experience of science.

Mars mission program for primary students: Building student and teacher skills in science, technology, engineering and mathematics

NASA Astrophysics Data System (ADS)

Mathers, Naomi; Pakakis, Michael; Christie, Ian

2011-09-01

The Victorian Space Science Education Centre (VSSEC) scenario-based programs, including the Mission to Mars and Mission to the Orbiting Space Laboratory, utilize methodologies such as hands-on applications, immersive learning, integrated technologies, critical thinking and mentoring. The use of a scenario provides a real-life context and purpose to what students might otherwise consider disjointed information. These programs engage students in the areas of maths and science, and highlight potential career paths in science and engineering. The introduction of a scenario-based program for primary students engages students in maths and science at a younger age, addressing the issues of basic numeracy and science literacy, thus laying the foundation for stronger senior science initiatives. Primary students absorb more information within the context of the scenario, and presenting information they can see, hear, touch and smell creates a memorable learning and sensory experience. The mission also supports development of teacher skills in the delivery of hands-on science and helps build their confidence to teach science. The Primary Mission to the Mars Base gives primary school students access to an environment and equipment not available in schools. Students wear flight suits for the duration of the program to immerse them in the experience of being an astronaut. Astronauts work in the VSSEC Space Laboratory, which is transformed into a Mars base for the primary program, to conduct experiments in areas such as robotics, human physiology, microbiology, nanotechnology and environmental science. Specialist mission control software has been developed by La Trobe University Centre for Games Technology to provide age appropriate Information and Communication Technology (ICT) based problem solving and support the concept of a mission. Students in Mission Control observe the astronauts working in the space laboratory and talk to them via the AV system. This interactive environment promotes high order thinking skills such as problem solving, team work, communication skills and leadership. To promote the teaching of science in the classroom, and prepare the students for their mission, the program includes a pre-visit program. These classroom-based lessons model best practice in effective science teaching and learning to support the development of confident primary science teachers.

The symposium included a learning exercise the following day for a planetary design workshop at the European Space Research and Technology Centre (ESTEC) for 30 motivated students, the majority being from GeoVUsie with little previous experience of planetary science. Students were split into five teams and assigned pre-selected new science mission projects. A few scientific papers were given to use as reference just days before the workshop. Three hours were allocated to create a mission concept before presenting results to the other students and science advisors. The educational backgrounds varied from second year undergraduate students to masters' students from mostly local universities.The lunar team was told to design a mission to the lunar south pole, as this is a key destination agreed upon by the international lunar scientific community. This region has the potential to address many significant objectives for planetary science, as the South Pole-Aitken basin has preserved early solar system history and would help to understand impact events throughout the solar system as well as the origin and evolution of the Earth-Moon system, particularly if samples could be returned. This report shows the lunar team's mission concept and reasons for studying the origin of volatiles on the Moon as the primary science objective [1]. Amundsen crater was selected as the optimal landing site near the lunar south pole [2]. Other mission concepts such as RESOLVE [3], L-VRAP [4], ESA's lunar lander studies and Luna-27 were reviewed. A rover and drill were selected as being the most suitable architecture for the requirements of this mission. Recommendations for future student planetary design exercises were to continue events like this, ideally with more time, and also to invite a more diverse range of educational backgrounds, i.e., both engineering and science students/professionals.

2004-01-01

The Johns Hopkins University and Space Telescope Science Institute are working together on this project to develop a library of standard software for data archives that will benefit the wider astronomical community. The ultimate goal was to develop and distribute a software library aimed at providing a common system for partitioning and indexing the sky in manageable sized regions and provide complex queries on the objects stored in this system. Whilst ongoing maintenance work will continue the primary goal has been completed. Most of the next generation sky surveys in the different wavelengths like 2MASS, GALEX, SDSS, GSC-II, DPOSS and FIRST have agreed on this common set of utilities. In this final report, we summarize work on the work elements assigned to the STScI project team.

The Explored Asteroids: Science and Exploration in the Space Age

Interest in asteroids is currently high in view of their scientific importance, the impact hazard, and the in situ resource opportunities they offer. They are also a case study of the intimate relationship between science and exploration. A detailed review of the twelve asteroids that have been visited by eight robotic spacecraft is presented here. While the twelve explored asteroids have many features in common, like their heavily cratered and regolith covered surfaces, they are a remarkably diverse group. Some have low-eccentricity orbits in the main belt, while some are potentially hazardous objects. They range from dwarf planets to primary planetesimals to fragments of larger precursor objects to tiny shards. One has a moon. Their surface compositions range from basaltic to various chondrite-like compositions. Here their properties are reviewed and what was confirmed and what was newly learned is discussed, and additionally the explored asteroids are compared with comets and meteorites. Several topics are developed. These topics are the internal structure of asteroids, water distribution in the inner solar system and its role in shaping surfaces, and the meteoritic links.

Remote Sensing in Geography in the New Millennium: Prospects, Challenges and Opportunities

As noted in the first edition of Geography in America, the term remote sensing was coined in the early 1960's by geographers to describe the process of obtaining data by use of both photographic and nonphotographic instruments. Although this is still a working definition today, a more explicit and updated definition as it relates to geography can be phrased as: "remote sensing is the science, art, and technology of identifying, characterizing, measuring, and mapping of Earth surface, and near earth surface, phenomena from some position above using photographic or nonphotographic instruments." Both patterns and processes may be the object of investigation using remote sensing data. The science dimension of geographic remote sensing is rooted in the fact that: a) it is dealing with primary data, wherein the investigator must have an understanding of the environmental phenomena under scrutiny, and b) the investigator must understand something of the physics of the energy involved in the sensing instrument and the atmospheric pathway through which the energy passes from the energy source, to the Earth object to the sensor.

The mission patch for STS-85 is designed to reflect the broad range of science and engineering payloads on the flight. The primary objectives of the mission were to measure chemical constituents in Earth’s atmosphere with a free-flying satellite and to flight-test a new Japanese robotic arm designed for use on the International Space Station (ISS). STS-85 was the second flight of the satellite known as Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere-Shuttle Pallet Satellite-2 CRISTA-SPAS-02. CRISTA, depicted on the right side of the patch pointing its trio of infrared telescopes at Earth’s atmosphere, stands for Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere. The high inclination orbit is shown as a yellow band over Earth’s northern latitudes. In the Space Shuttle Discovery’s open payload bay an enlarged version of the Japanese National Space Development Agency’s (NASDA) Manipulator Flight Demonstration (MFD) robotic arm is shown. Also shown in the payload bay are two sets of multi-science experiments: the International Extreme Ultraviolet Hitchhiker (IEH-02) nearest the tail and the Technology Applications and Science (TAS-01) payload. Jupiter and three stars are shown to represent sources of ultraviolet energy in the universe. Comet Hale-Bopp, which was visible from Earth during the mission, is depicted at upper right. The left side of the patch symbolizes daytime operations over the Northern Hemisphere of Earth and the solar science objectives of several of the payloads.

The Design and Use of Planetary Science Video Games to Teach Content while Enhancing Spatial Reasoning Skills

NASA Astrophysics Data System (ADS)

Ziffer, Julie; Nadirli, Orkhan; Rudnick, Benjamin; Pinkham, Sunny; Montgomery, Benjamin

2016-10-01

Traditional teaching of Planetary Science requires students to possess well developed spatial reasoning skills (SRS). Recent research has demonstrated that SRS, long known to be crucial to math and science success, can be improved among students who lack these skills (Sorby et al., 2009). Teaching spatial reasoning is particularly valuable to women and minorities who, through societal pressure, often doubt their abilities (Hill et al., 2010). To address SRS deficiencies, our team is developing video games that embed SRS training into Planetary Science content. Our first game, on Moon Phases, addresses the two primary challenges faced by students trying to understand the Sun-Earth-Moon system: 1) visualizing the system (specifically the difference between the Sun-Earth orbital plane and the Earth-Moon orbital plane) and 2) comprehending the relationship between time and the position-phase of the Moon. In our second video game, the student varies an asteroid's rotational speed, shape, and orientation to the light source while observing how these changes effect the resulting light curve. To correctly pair objects to their light curves, students use spatial reasoning skills to imagine how light scattering off a three dimensional rotating object is imaged on a sensor plane and is then reduced to a series of points on a light curve plot. These two games represent the first of our developing suite of high-interest video games designed to teach content while increasing the student's competence in spatial reasoning.

2018-01-01

Implementation Science is commonly described as the study of methods and approaches that promote the uptake and use of evidence-based interventions into routine practice and policymaking. In this issue of JABFM , investigators share a wealth of new insights from the frontlines of Implementation Science in primary care: what it is, how we are doing it, and how it is advancing the evidence base of primary care. The breadth of implementation science in primary care is affirmed by the range of topics covered, from thought leader recommendations on future directions for the field, to reports on how best practices in policy and practice are shaping primary care implementation in the United States and Canada. There are also important updates on agents of primary care implementation themselves, such as practice facilitators, geriatric care teams, and family physicians interested in providing obstetric care. Other articles report on novel practice transformation efforts that advance health promotion and disease prevention, and innovative approaches to identifying and addressing social determinants of health in primary care practices and the communities they serve. The articles seem to generate as many new questions as they answer, and highlight the need for continued emphasis on advancing the science of implementation in primary health care. © Copyright 2018 by the American Board of Family Medicine.

Europa Small Lander Design Concepts

NASA Astrophysics Data System (ADS)

Zimmerman, W. F.

2005-12-01

Title: Europa Small Lander Design Concepts Authors: Wayne F. Zimmerman, James Shirley, Robert Carlson, Tom Rivellini, Mike Evans One of the primary goals of NASA's Outer Planets Program is to revisit the Jovian system. A new Europa Geophysical Explorer (EGE) Mission has been proposed and is under evaluation. There is in addition strong community interest in a surface science mission to Europa. A Europa Lander might be delivered to the Jovian system with the EGE orbiter. A Europa Astrobiology Lander (EAL) Mission has also been proposed; this would launch sometime after 2020. The primary science objectives for either of these would most likely include: Surface imaging (both microscopic and near-field), characterization of surface mechanical properties (temperature, hardness), assessment of surface and near-surface organic and inorganic chemistry (volatiles, mineralogy, and compounds), characterization of the radiation environment (total dose and particles), characterization of the planetary seismicity, and the measurement of Europa's magnetic field. The biggest challenges associated with getting to the surface and surviving to perform science investigations revolve around the difficulty of landing on an airless body, the ubiquitous extreme topography, the harsh radiation environment, and the extreme cold. This presentation reviews some the recent design work on drop-off probes, also called "hard landers". Hard lander designs have been developed for a range of science payload delivery systems spanning small impactors to multiple science pods tethered to a central hub. In addition to developing designs for these various payload delivery systems, significant work has been done in weighing the relative merits of standard power systems (i.e., batteries) against radioisotope power systems. A summary of the power option accommodation benefits and issues will be presented. This work was performed at the Jet Propulsion Laboratory, California Institute of Technology, under a contract from NASA,

Enhancing literacy practices in science classrooms through a professional development program for Canadian minority-language teachers

NASA Astrophysics Data System (ADS)

Rivard, Léonard P.; Gueye, Ndeye R.

2016-05-01

Literacy in the Science Classroom Project was a three-year professional development (PD) program supporting minority-language secondary teachers' use of effective language-based instructional strategies for teaching science. Our primary objective was to determine how teacher beliefs and practices changed over time and how these were enacted in different classrooms. We also wanted to identify the challenges and enablers to implementing these literacy strategies and practices at the classroom, school, and district levels. Data collection involved both qualitative and quantitative methodologies: student questionnaires; interviews with teachers, principals, and mentor; and focus groups with students. The findings suggest that the program had an impact on beliefs and practices commensurate with the workshop participation of individual teachers. These language-enhanced teacher practices also had a positive impact on the use of talking, reading and writing by students in the science classroom. Finally, continuing PD support may be needed in certain jurisdictions for strengthening minority-language programs given the high teacher mobility in content-area classrooms evident in this study.

How a science methods course may influence the curriculum decisions of preservice teachers in the Bahamas

NASA Astrophysics Data System (ADS)

Wisdom, Sonya L.

The purpose of this study was to examine how a science methods course in primary education might influence the curriculum decisions of preservice teachers in The Bahamas related to unit plan development on environmental science topics. Grounded in a social constructivist theoretical framework for teaching and learning science, this study explored the development of the confidence and competence of six preservice teachers to teach environmental science topics at the primary school level. A qualitative case study using action research methodologies was conducted. The perspectives of preservice teachers about the relevancy of methods used in a science methods course were examined as I became more reflective about my practice. Using constant comparative analysis, data from student-written documents and interviews as well as my field notes from class observations and reflective journaling were analyzed for emerging patterns and themes. Findings of the study indicated that while preservice teachers showed a slight increase in interest regarding learning and teaching environmental science, their primary focus during the course was learning effective teaching strategies in science on topics with which they already had familiarity. Simultaneously, I gained a deeper understanding of the usefulness of reflection in my practice. As a contribution to the complexity of learning to teach science at the primary school level, this study suggests some issues for consideration as preservice teachers are supported to utilize more of the national primary science curriculum in The Bahamas.

We have completed a search for slow moving bodies in the data obtained by the Pan-STARRS-1 (PS1) Science Consortium from 2010 to 2014. The data set covers the full sky north of -30 degrees declination, in the PS1 g, r, i, z, y, and w (g+r+i) filters. Our novel distance-based search is effective at detecting and linking very slow moving objects with sparsely sampled observations, even if observations are widely separated in RA, Dec and time, which is relevant to the future LSST solar system searches. In particular, our search is sensitive to objects at heliocentric distances of 25-2000 AU with magnitudes brighter than approximately r=22.5, without limits on the inclination of the object. We recover hundreds of known TNOs and Centaurs and discover hundreds of new objects, measuring phase and color information for many of them. Other highlights include the discovery of a second retrograde TNO, a number of Neptune Trojans, and large numbers of distant resonant TNOs.

New Dimensions of GIS Data: Exploring Virtual Reality (VR) Technology for Earth Science

NASA Astrophysics Data System (ADS)

Skolnik, S.; Ramirez-Linan, R.

2016-12-01

NASA's Science Mission Directorate (SMD) Earth Science Division (ESD) Earth Science Technology Office (ESTO) and Navteca are exploring virtual reality (VR) technology as an approach and technique related to the next generation of Earth science technology information systems. Having demonstrated the value of VR in viewing pre-visualized science data encapsulated in a movie representation of a time series, further investigation has led to the additional capability of permitting the observer to interact with the data, make selections, and view volumetric data in an innovative way. The primary objective of this project has been to investigate the use of commercially available VR hardware, the Oculus Rift and the Samsung Gear VR, for scientific analysis through an interface to ArcGIS to enable the end user to order and view data from the NASA Discover-AQ mission. A virtual console is presented through the VR interface that allows the user to select various layers of data from the server in both 2D, 3D, and full 4pi steradian views. By demonstrating the utility of VR in interacting with Discover-AQ flight mission measurements, and building on previous work done at the Atmospheric Science Data Center (ASDC) at NASA Langley supporting analysis of sources of CO2 during the Discover-AQ mission, the investigation team has shown the potential for VR as a science tool beyond simple visualization.

Primary Objective Grating Astronomical Telescope

NASA Technical Reports Server (NTRS)

Ditto, Thomas D.

2007-01-01

It has been 370 years since a seventeenth century French mathematician, Mersenne, presciently sketched out an astronomical telescope based on dual parabolic reflectors. Since that time the concept of the primary objective has been virtually unchanged. Now a new class of astronomical telescope with a primary objective grating (POG) has been studied as an alternative. The POG competes with mirrors, in part, because diffraction gratings provide the very chromatic dispersion that mirrors defeat. The resulting telescope deals effectively with long-standing restrictions on multiple object spectroscopy (MOS). Other potential benefits include unprecedented apertures and collection areas. The new design also favors space deployment as a gossamer membrane. The inventor, Tom Ditto, first discovered that higher-order diffraction images contain hidden depth cues, for which he was granted a seminal range finding patent in 1987. Subsequently, he invented and patented 3D localizers, profilometers and microscopes using POGs. The POG telescope was placed in the public domain to expedite research. The function of a telescopes primary objective is to collect flux and to deliver images. Both functions dictate that size matters, and bigger is better. For that reason, there has been a steady push over the past century to ramp up the size of the primary mirror. However, for every doubling of mirror diameter, the elapsed time between initial effort and first light has also doubled. Meanwhile, costs escalated beyond the mirror alone, because larger instruments required larger enclosures and better pointing mechanisms. One key catalog of observation, spectrographic data, is far more difficult to amass than two-dimensional imagery. While the number of observable objects has increased with mirror size, the capacity to take spectra has not increased proportionately. In the best of circumstances, spectrograms are available for one per cent of the all objects surveyed. Spectroscopy was a historical afterthought introduced in the nineteenth century shortly after the invention of the diffraction grating and over a century after Newtons 1670 telescope. Spectroscopy is generally accomplished using a diffraction grating as the disperser in the secondary. The light being delivered to the spectrograph is first captured by a primary mirror which provides no chromatic magnification by itself. Sizeable spectrographs could not be deployed while diffraction gratings were rare commodities scribed using mechanical ruling engines that produced one grating line at a time. Today diffraction gratings are commonplace. Their recent availability is a product of both the invention of holography and the mass replication of surface microstructures. Holography permits all lines in a grating to be made simultaneously in a single photographic exposure. Holograms can then be reproduced by embossing processes. The improvement in replication is analogous to how Gutenberg changed the availability of books. The masters may be expensive, but the copies are not. Computer science is another technology that emerged in the second half of the twentieth century without which our proposed spectrographic instrument could not function due to the complexity of image processing required in data reduction. The employment of very large diffraction gratings as primary objectives for astronomical telescopes requires a novel

Microgravity Disturbance Characterization of the Quench Module Insert (QMI) Phase Change Device (PCD)

NASA Technical Reports Server (NTRS)

Gattis, Christy; Rodriguez, Pete (Technical Monitor)

2000-01-01

The Materials Science Research Facility (MSRF) is a multi-user, multi-purpose facility for materials science research. One experiment within the MSRF will be the Quench Module Insert (QMI), a high-temperature furnace with unique capabilities for processing different classes of materials. The primary functions of the QMI furnace are to melt, directionally solidify, and quench metallic samples, providing data to aid in understanding the effects of the microgravity environment on the characteristics of these processed metals. The QMI houses sealed individual sample ampoules containing material to be processed. Quenching of the samples in the QMI furnace is accomplished by releasing low-melting-point metallic shoes into contact with the outside of the sample ampoule, dissipating heat and cooling the sample inside. The impact from this method of quench will induce sample vibrations which could be large enough to adversely affect sample quality. Utilizing breadboard hardware, the sample quench sequence, releasing the shoes, was conducted. Data was collected from accelerometers located on the breadboard sample cartridge, indicating the maximum acceleration achieved by the sample. The primary objective of the test described in this presentation was to determine the acceleration imparted on the sample by the shoe contact. From this information, the science community can better assess whether this method of quench will allow them to obtain the data they need.

Using Scavenger Hunts to Familiarize Students with Scientific Journal Articles.

Primary scientific literature can be difficult to navigate for anyone unfamiliar with its foreign, formal structure. We sought to create a fun, easy learning tool to help familiarize students of all ages with the structure of a scientific article. Our main learning objective was for the student to realize that science writing is formulaic-that specific information is found in predictable locations within an article-and that, with an understanding of the formula, anyone can comfortably navigate any journal article and accurately predict what to expect to find in each section. To this end, we designed a Journal Article Scavenger Hunt that requires the user to find and identify a series of commonplace features of a primary research article. The scavenger hunt activity is quick and easy to implement, and is adaptable to various ages and settings, including the classroom, lab, and at outreach events. The questions in the scavenger hunt can be scaled in difficulty and specificity to suit the instructor's needs. Over many years of using this activity, we have received positive feedback from students of all ages, from elementary school students to lay adult-learners as well as science teachers themselves. By making the unknown seem predictable and approachable, the scavenger hunt helps a variety of audiences feel more comfortable with science and more confident in their ability to engage directly with the scientific literature.

Paolini, Mara

2013-04-01

The school where I worked in 2011,was for primary school teachers-to-be. Classes were formed by a high number of students with a handicapped student in each class. The school was attended mainly by girls with low self-esteem and difficulties in fulfilling their homework. Moreover secondary school students often find science far from their world and rather boring. So helping them understand the relationship between science and everyday life, between chemistry and society was my main objective . Simple / elementary experiments were chosen : if presented and carried out with scientific method, they can prove very useful in the development of specific abilities, from simple observation to the more complex and vital ability to grasp cause and effect relation. I think that the direct observation of facts and phenomena is the foundation to stimulate the process of learning and abstracting experiments: A. The pressure as a force, the behavior of the hot and cold water. 1. the implosion of the can 2. the candle 3. the balloon and the bottle 4. the egg in the bottle Monitoring and evaluation The direct observation of students during operations and final written reports were the ways which was evaluated the project. Results of the project carried out: The students were able to use scientific language correctly, to explain the phenomenon to primary school children using their own ideas. they also devised a table where to list the experiments carried out

Challenges of In-Flight Calibrations for the Mars Reconnaissance Orbiter Payload

NASA Technical Reports Server (NTRS)

Xaypraseuth, Peter

2007-01-01

The Mars Reconnaissance Orbiter is the most complex spacecraft that has ever been sent to investigate the Red Planet. A major part of what makes this mission so complex is the suite of instruments that were selected. The instruments on MRO vary from a simple imaging system, not much larger than a pocket knife to the largest camera ever flown to another planet. Not only does the size of the instruments vary, so do the scientific investigations associated with each instrument. In order to ensure that this payload suite would be able to satisfy all of its science objectives, a major effort was put forth by the MRO Project to ensure these instruments were well calibrated prior to the start of the Primary Science Phase. The in-flight calibration plan for MRO proved to be quite challenging, given the often conflicting requirements due to the varying capability of each of the instruments and the desire to constrain the workload on the Mission Operations personnel. The quality of data returned by MRO since the start of the Primary Science Phase is a tribute to the effort that was put forth to characterize the in-flight performance of the instruments. This paper will describe the challenges associated with the planning and implementation of the various calibration events on MRO, and will exhibit some of the results from those calibrations.

The Lunar Reconnaissance Orbiter (LRO) mission is the first of a series of lunar robotic spacecraft scheduled for launch in Fall 2008. LRO will spend at least one year in a low altitude polar orbit around the Moon, collecting lunar environment science and mapping data to enable future human exploration. The LRO employs a 3-axis stabilized attitude control system (ACS) whose primary control mode, the "Observing mode", provides Lunar Nadir, off-Nadir, and Inertial fine pointing for the science data collection and instrument calibration. The controller combines the capability of fine pointing with that of on-demand large angle full-sky attitude reorientation into a single ACS mode, providing simplicity of spacecraft operation as well as maximum flexibility for science data collection. A conventional suite of ACS components is employed in this mode to meet the pointing and control objectives. This paper describes the design and analysis of the primary LRO fine pointing and attitude re-orientation controller function, known as the "Observing mode" of the ACS subsystem. The control design utilizes quaternion feedback, augmented with a unique algorithm that ensures accurate Nadir tracking during large angle yaw maneuvers in the presence of high system momentum and/or maneuver rates. Results of system stability analysis and Monte Carlo simulations demonstrate that the observing mode controller can meet fine pointing and maneuver performance requirements.

This article outlines how learning objectives based upon science, technology and society (STS) elements for Palestinian ninth grade science textbooks were identified, which was part of a bigger study to establish an STS foundation in the ninth grade science curriculum in Palestine. First, an initial list of STS elements was determined. Second, using this list, ninth grade science textbooks and curriculum document contents were analyzed. Third, based on this content analysis, a possible list of 71 learning objectives for the integration of STS elements was prepared. This list of learning objectives was refined by using a two-round Delphi technique. The Delphi study was used to rate and to determine the consensus regarding which items (i.e. learning objectives for STS in the ninth grade science textbooks in Palestine) are to be accepted for inclusion. The results revealed that of the initial 71 objectives in round one, 59 objectives within round two had a mean score of 5.683 or higher, which indicated that the learning objectives could be included in the development of STS modules for ninth grade science in Palestine.

Scientists' Prioritization of Communication Objectives for Public Engagement.

PubMed

Dudo, Anthony; Besley, John C

2016-01-01

Amid calls from scientific leaders for their colleagues to become more effective public communicators, this study examines the objectives that scientists' report drive their public engagement behaviors. We explore how scientists evaluate five specific communication objectives, which include informing the public about science, exciting the public about science, strengthening the public's trust in science, tailoring messages about science, and defending science from misinformation. We use insights from extant research, the theory of planned behavior, and procedural justice theory to identify likely predictors of scientists' views about these communication objectives. Results show that scientists most prioritize communication designed to defend science from misinformation and educate the public about science, and least prioritize communication that seeks to build trust and establish resonance with the public. Regression analyses reveal factors associated with scientists who prioritize each of the five specific communication objectives. Our findings highlight the need for communication trainers to help scientists select specific communication objectives for particular contexts and audiences.

Research on the value of medical library services: does it make an impact in the health care literature?*

PubMed Central

Sherwill-Navarro, Pamela J.; Wallace, Addajane L.

2004-01-01

Objective: To evaluate the impact in the health care literature of research articles that provided evidence of the value of library services (including MEDLINE) as an element of quality health care. Data Sources/Selection: Four research articles on the relationship between use of library services and quality health care were selected as “primary articles” from a MEDLINE search using appropriate Medical Subject Heading. Primary articles met the following criteria: written in English, reported research, related to clinical care, and published before 1995. Data Extraction: The technique of citation analysis was used to measure the impact of the primary articles on the subsequent literature. The number, authorship, type, and publication venue of articles citing the primary articles were determined using ISI Web of Science, MEDLINE, other electronic resources, and the citing articles themselves. For the 146 English-language citing articles, the article type (i.e., advocacy, instructional, research) was noted; and, for those that reported research, the use to which the author put the cited material was determined. Results: The primary articles were cited more often than the average articles published that year in the same journals. At the time of the study each article had been cited almost every year since publication. Of the 146 citing articles written in English, 43% were written by librarians, 38% by physicians, 12% by librarians with physicians. The majority were published in medical journals, followed in order of decreasing frequency by the Bulletin of the Medical Library Association, information science journals, and health administration journals. Conclusions: The results of this study demonstrate that published research on the value of medical library services has an impact on the literature. These articles are read and cited and continue to be of value. PMID:14762461

Where do teens go to get the 411 on sexual health? A teen intern in clinical research with teens.

PubMed

Reznik, Yana; Tebb, Kathleen

2008-01-01

Research Setting: The research for the study reported here was conducted in conjunction with the Biomedical and Health Sciences Internship for High School Students at the University of California, San Francisco, Department of Pediatrics. The eight-week intensive summer program promotes interest in science, medicine, and health among young people by introducing students to the professional world of science, broadly defined. Interns are expected to assist in a specific research project that addresses a scientific question. They participate in a variety of lectures and are exposed to faculty members, medical students, and college graduates working as research assistants in a rich academic and clinical research setting. This study was conducted within Kaiser Permanente (KP) of Northern California as part of a larger study aimed at increasing Chlamydia screening among sexually active adolescents. It was approved by Committee on Human Research, the institutional review board (IRB) for the University of California, San Francisco and the IRB for KP Northern California. There were two primary objectives of this study: first, we sought to identify where teenagers obtain information about sexual health; second, we examined whether aspects of a clinician's communication style with a teen during a health care visit were associated with the teen choosing that clinician as a primary source of sexual health information (as compared with parents, peers, teachers, the news media, and other sources). Teens who perceived that their clinician communicated with respect and explained information in ways that they could understand were more likely to cite their clinician as a source of sexual health information. Having time alone (confidentiality) with a physician was also associated with teens' selection of a clinician as a primary information source. Whether the clinician asked about sex during the health care visit was significantly associated with males selecting the clinician as a primary source of sexual health information. An important finding, at least for males, because teens do not always bring up the topic.

This cross-sectional study describes the characteristics and trends of health sciences-related studies published in Ecuador from 1999-2009. Its objective is to contribute to the design and implementation of a research and development policy whose work is centered on the country's health priorities. Bibliometric indicators of production applied to publications in health sciences in Ecuador were used for the analysis. The publications were from the LILACS and MEDLINE databases. It was found that 625 articles were published from 1999-2009, primarily in the clinical-surgical areas (60%), followed by epidemiology (17.4%), basic sciences (14.1%), and health systems (8.5%). Only 4.3% and 7.2% of the production in this period was related to the primary causes of morbidity and mortality, respectively. It was found that private institutions generated more health research than public institutions, and hospitals (public, private, and mixed) produced a higher percentage than universities. The analysis showed that there was limited scientific production in health sciences in Ecuador during the study period, with a slight increase in the last two years that may be due in part to greater investment in research and development by the National Secretariat of Science and Technology (SENACYT). Investment increased from 0.20% to 0.44% of gross domestic product between 2006 and 2009.

Soil Science Education for Primary and Secondary Students

NASA Astrophysics Data System (ADS)

Sparrow, Elena; Yoshikawa, Kenji; Kopplin, Martha

2013-04-01

Soils is one of the science investigation areas in the Global learning and Observations to Benefit the Environment (GLOBE), an international science and education program (112 countries) that teaches primary and secondary students to learn science by doing science. For each area of investigation GLOBE provides background information, measurement protocols and learning activities compiled as a chapter in the GLOBE Teacher's Guide. Also provided are data sheets and field guides to assist in the accurate collection of data as well as suggestions of scientific instruments and calibration methods. Teachers learn GLOBE scientific measurement protocols at professional development workshops led by scientists and educators, who then engage their students in soil studies that also contribute to ongoing science investigations. Students enter their data on the GLOBE website and can access their data as well as other data contributed by students from other parts of the world. Soil characterization measurements carried out in the field include site description, horizon depths, soil structure, soil color, soil consistence, soil texture, roots, rocks and carbonates. Other field measurements are soil temperature and soil moisture monitoring while the following measurements are carried out in the classroom or laboratory: gravimetric soil moisture, bulk density, particle density, particle size distribution, pH and soil fertility (nitrogen, phosphorus and potassium). Learning activities provide support for preparing students to do the measurements and for better understanding of science concepts. Many countries in GLOBE have adopted standards for education including science education with commonalities among them. For the Teacher's Guide, the National Science Education Standards published by the US National Academy of Sciences, selected additional content standards that GLOBE scientists and educators feel are appropriate and the National Geography Standards prepared by the (US) National Education Standards Project, are being used. Educational objectives for students include gaining scientific inquiry abilities in addition to understanding scientific concepts. The Soils chapter also includes some suggestions for managing students in the field and classroom. A new protocol has also been developed by the Seasons and Biomes project, one of the GLOBE earth system science projects. Active Layer monitoring uses a Frost Tube that measures when and how deeply soil freezes and is currently being used in more than 200 sites in Alaska. Teachers have successfully implemented soil studies in their curriculum and have used it to teach about the science process.

Parker Solar Probe: A NASA Mission to Touch the Sun: Mission Status Update

Fox, N. J.

2017-12-01

The newly renamed, Parker Solar Probe (PSP) mission will be the first mission to fly into the low solar corona, revealing how the corona is heated and the solar wind and energetic particles are accelerated, solving fundamental mysteries that have been top priority science goals since such a mission was first proposed in 1958. The scale and concept of such a mission has been revised at intervals since that time, yet the core has always been a close encounter with the Sun. The primary science goal of the Parker Solar Probe mission is to determine the structure and dynamics of the Sun's coronal magnetic field, understand how the solar corona and wind are heated and accelerated, and determine what mechanisms accelerate and transport energetic particles. PSP uses an innovative mission design, significant technology development and a risk-reducing engineering development to meet the science objectives. In this presentation, we provide an update on the progress of the Parker Solar Probe mission as we prepare for the July 2018 launch.

2014-01-01

Within health science programs there has been a call for more faculty development, particularly for teaching and learning. The primary objectives of this review were to describe the current landscape for faculty development programs for teaching and learning and make recommendations for the implementation of new faculty development programs. A thorough search of the pertinent health science databases was conducted, including the Education Resource Information Center (ERIC), MEDLINE, and EMBASE, and faculty development books and relevant information found were reviewed in order to provide recommendations for best practices. Faculty development for teaching and learning comes in a variety of forms, from individuals charged to initiate activities to committees and centers. Faculty development has been effective in improving faculty perceptions on the value of teaching, increasing motivation and enthusiasm for teaching, increasing knowledge and behaviors, and disseminating skills. Several models exist that can be implemented to support faculty teaching development. Institutions need to make informed decisions about which plan could be most successfully implemented in their college or school. PMID:24954939

Working Alongside Scientists. Impacts on Primary Teacher Beliefs and Knowledge About Science and Science Education

NASA Astrophysics Data System (ADS)

Anderson, Dayle; Moeed, Azra

2017-05-01

Current curriculum demands require primary teachers to teach about the Nature of Science; yet, few primary teachers have had opportunity to learn about science as a discipline. Prior schooling and vicarious experiences of science may shape their beliefs about science and, as a result, their science teaching. This qualitative study describes the impact on teacher beliefs about science and science education of a programme where 26 New Zealand primary (elementary) teachers worked fulltime for 6 months alongside scientists, experiencing the nature of work in scientific research institutes. During the 6 months, teachers were supported, through a series of targeted professional development days, to make connections between their experiences working with scientists, the curriculum and the classroom. Data for the study consisted of mid- and end-of-programme written teacher reports and open-ended questionnaires collected at three points, prior to and following 6 months with the science host and after 6 to 12 months back in school. A shift in many teachers' beliefs was observed after the 6 months of working with scientists in combination with curriculum development days; for many, these changes were sustained 6 to 12 months after returning to school. Beliefs about the aims of science education became more closely aligned with the New Zealand curriculum and its goal of developing science for citizenship. Responses show greater appreciation of the value of scientific ways of thinking, deeper understanding about the nature of scientists' work and the ways in which science and society influence each other.

Europa Explorer - An Exceptional Mission Using Existing Technology

NASA Technical Reports Server (NTRS)

Clark, Karla B.

2007-01-01

A mission to Europa has been identified as a high priority by the science community for several years. The difficulty of an orbital mission, primarily due to the propulsive requirements and Jupiter's trapped radiation, led to many studies which investigated various approaches to meeting the science goals. The Europa Orbiter Mission studied in the late 1990's only met the most fundamental science objectives. The science objectives have evolved with the discoveries from the Galileo mission. JPL studied one concept, Europa Explorer, for a Europa orbiting mission which could meet a much expanded set of science objectives. A study science group was formed to verify that the science objectives and goals were being adequately met by the resulting mission design concept. The Europa Explorer design emerged primarily from two key self-imposed constraints: 1) meet the full set of identified nonlander science objectives and 2) use only existing technology.

This paper reports a two-year longitudinal study of the effects of cooperative learning on science attainment, attitudes towards science, and social connectedness during transition from primary to high school. A previous project on cooperative learning in primary schools observed gains in science understanding and in social aspects of school life. This project followed 204 children involved in the previous project and 440 comparison children who were not as they undertook transition from 24 primary schools to 16 high schools. Cognitive, affective, and social gains observed in the original project survived transition. The implications improving the effectiveness of school transition by using cooperative learning initiatives are explored. Possibilities for future research and the implications for practice and policy are discussed.

Formative and summative assessment of science in English primary schools: evidence from the Primary Science Quality Mark

NASA Astrophysics Data System (ADS)

Earle, Sarah

2014-05-01

Background:Since the discontinuation of Standard Attainment Tests (SATs) in science at age 11 in England, pupil performance data in science reported to the UK government by each primary school has relied largely on teacher assessment undertaken in the classroom. Purpose:The process by which teachers are making these judgements has been unclear, so this study made use of the extensive Primary Science Quality Mark (PSQM) database to obtain a 'snapshot' (as of March 2013) of the approaches taken by 91 English primary schools to the formative and summative assessment of pupils' learning in science. PSQM is an award scheme for UK primary schools. It requires the science subject leader (co-ordinator) in each school to reflect upon and develop practice over the course of one year, then upload a set of reflections and supporting evidence to the database to support their application. One of the criteria requires the subject leader to explain how science is assessed within the school. Sample:The data set consists of the electronic text in the assessment section of all 91 PSQM primary schools which worked towards the Quality Mark in the year April 2012 to March 2013. Design and methods:Content analysis of a pre-existing qualitative data set. Text in the assessment section of each submission was first coded as describing formative or summative processes, then sub-coded into different strategies used. Results:A wide range of formative and summative approaches were reported, which tended to be described separately, with few links between them. Talk-based strategies are widely used for formative assessment, with some evidence of feedback to pupils. Whilst the use of tests or tracking grids for summative assessment is widespread, few schools rely on one system alone. Enquiry skills and conceptual knowledge were often assessed separately.
