A workload model and measures for computer performance evaluation

NASA Technical Reports Server (NTRS)

Kerner, H.; Kuemmerle, K.

1972-01-01

A generalized workload definition is presented which constructs measurable workloads of unit size from workload elements, called elementary processes. An elementary process makes almost exclusive use of one of the processors, CPU, I/O processor, etc., and is measured by the cost of its execution. Various kinds of user programs can be simulated by quantitative composition of elementary processes into a type. The character of the type is defined by the weights of its elementary processes and its structure by the amount and sequence of transitions between its elementary processes. A set of types is batched to a mix. Mixes of identical cost are considered as equivalent amounts of workload. These formalized descriptions of workloads allow investigators to compare the results of different studies quantitatively. Since workloads of different composition are assigned a unit of cost, these descriptions enable determination of cost effectiveness of different workloads on a machine. Subsequently performance parameters such as throughput rate, gain factor, internal and external delay factors are defined and used to demonstrate the effects of various workload attributes on the performance of a selected large scale computer system.
M{sub 2}X intermetallics: Nonmetal insertion in a h.c.-like metallic distribution

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

Pivan, J.Y.; Guerin, R.

A simple structural model is proposed on the basis of an ideal hexagonal close-packing (AB){sup {infinity}} of the metal atoms M. The metalloid atoms X, located in an ordered manner in the metallic planes with the stacking sequence ..(A){sup {infinity}}.. or ..(B){sup {infinity}}.., generate two types of elementary units called units U{sub I} and U{sub II}. These units are hexagonal prisms with the fundamental vectors a{sub 0}, b{sub 0}, c{sub 0} and the elementary volume V{sub 0}. When the exclusive occurrence of U{sub I} (or U{sub II}) only yields 6-prismatic and triangular sites of metalloid atoms X, additional tetrahedral andmore » pyramidal sites of X atoms are present when units U{sub I} and U{sub II} exist simultaneously. The structures of compounds with the general formula M{sub 2}X (M = 3d, 4d, 5d and (or) 4f, 5f elements, X = B, P, As, Sb, Si, Ge, {hor_ellipsis}) are described in terms of intergrowth mechanisms. Binary, ternary, or even quaternary structures of compounds, with M/X ratios equal or close to two, appear as superstructures of the elementary units. Insofar as no ordering is considered along the stacking direction, the vectorial combinations of the fundamental vectors in the form A = h.a{sub 0}+s.b{sub 0}, B = k.a{sub 0}+t.b{sub 0}, C = c{sub 0} result in supercells with the volume V = (h.t {minus} k.s).V{sub 0}. The attainable symmetry (hexagonal, tetragonal, orthorhombic, monoclinic, {hor_ellipsis}) strongly depends on the particular values of the integers h, s, k, t. The criteria of occurrence of various series of compounds are presented together with their crystallographic features and structural relationships are emphasized. Moreover, the model demonstrates that numerous compounds with the predicted unit cell parameters should be obtained in each crystal system.« less

[Continuity and discontinuity of the geomerida: the bionomic and biotic aspects].

PubMed

Kafanov, A I

2005-01-01

The view of the spatial structure of the geomerida (Earth's life cover) as a continuum that prevails in modern phytocoenology is mostly determined by a physiognomic (landscape-bionomic) discrimination of vegetation components. In this connection, geography of life forms appears as subject of the landscapebionomic biogeography. In zoocoenology there is a tendency of synthesis of alternative concepts based on the assumption that there are no absolute continuum and absolute discontinuum in the organic nature. The problem of continuum and discontinuum of living cover being problem of scale aries from fractal structure of geomerida. This problem arises from fractal nature of the spatial structure of geomerida. The continuum mainly belongs to regularities of topological order. At regional and subregional scale the continuum of biochores is rather rare. The objective evidences of relative discontinuity of the living cover are determined by significant alterations of species diversity at the regional, subregional and even topological scale Alternatively to conventionally discriminated units in physionomically continuous vegetation, the same biotic complexes, represented as operational units of biogeographical and biocenological zoning, are distinguished repeatedly and independently by different researchers. An area occupied by certain flora (fauna, biota) could be considered as elementary unit of biotic diversity (elementary biotic complex).

From coupled elementary units to the complexity of the glass transition.

PubMed

Rehwald, Christian; Rubner, Oliver; Heuer, Andreas

2010-09-10

Supercooled liquids display fascinating properties upon cooling such as the emergence of dynamic length scales. Different models strongly vary with respect to the choice of the elementary subsystems as well as their mutual coupling. Here we show via computer simulations of a glass former that both ingredients can be identified via analysis of finite-size effects within the continuous-time random walk framework. The subsystems already contain complete information about thermodynamics and diffusivity, whereas the coupling determines structural relaxation and the emergence of dynamic length scales.

[Structuro-functional units of the salivary and lacrimal glands].

PubMed

Kostilenko, Iu P; Mysliuk, I V; Deviatkin, E A

1986-09-01

By means of the multilayer graphic and plastic reconstruction methods using series of semithin sections, spatial tridimensional organization of the epithelial complexes and blood microcirculatory bed in the rat palatal salivary glands and the lacrimal gland of the human newborn have been studied. Since their ducts serve not only for discharging their secrete into the external medium, but also for accumulation (as collectors), the sublobular unit--adenomere should be referred to as a part of elementary level of organization of the epithelial complexes. The adenomere has in its composition a collecting centrally situating duct. However, while studying structure of the blood microcirculatory bed, it is found out that there is not any strict territorial correspondence between its functional units and structural units of the glandular epithelium. Nevertheless, giving a great importance to a tight syntopic connection of the collecting ducts of the adenomeres with the postcapillary venules (that belong to filtrating microvessels), these are sublobular units--adenomeres that are distinguished as structural-functional units in the glands.

Establishing a Community of Practice between an Elementary Educator and a Scientist as a Means of Professional Development

NASA Astrophysics Data System (ADS)

Dashoush, Nermeen

This dissertation reports on an ethnographic study to examine and detail emerging practices in a community of practice comprised of an elementary teacher and a scientist (microbiologist). The study was conducted in order to design a model for professional development. It also aimed to contribute to the limited research involving elementary educators and their work with scientists. Furthermore, extra attention was given to understanding how both the elementary teacher and the scientist benefitted from their participation in the community of practice created from working together in teaching and learning science as a form of professional development. This was in accordance with a community of practice framework, which details that a healthy community is one without a perception of hierarchy among members (Wenger, 1998). The elementary teacher and scientist as participants collaborated in the creation of a science unit for an afterschool program. A wide variety of data was collected, including: interviews, transcribed meetings, and online journals from both participants. The data was coded for reoccurring themes surrounding practices and shifts in perception about science teaching and learning that emerged from this community of practice as professional development. The findings have implications for practices that could be used as a foundational structure in future collaborations involving elementary teachers and scientists for elementary science professional development.

Units of analysis and kinetic structure of behavioral repertoires

PubMed Central

Thompson, Travis; Lubinski, David

1986-01-01

It is suggested that molar streams of behavior are constructed of various arrangements of three elementary constituents (elicited, evoked, and emitted response classes). An eight-cell taxonomy is elaborated as a framework for analyzing and synthesizing complex behavioral repertoires based on these functional units. It is proposed that the local force binding functional units into a smoothly articulated kinetic sequence arises from temporally arranged relative response probability relationships. Behavioral integration is thought to reflect the joint influence of the organism's hierarchy of relative response probabilities, fluctuating biological states, and the arrangement of environmental and behavioral events in time.

[The cell theory. Progress in studies on cell-cell communications].

PubMed

Brodskiĭ, V Ia

2009-01-01

Current data confirm the fundamental statement of the cell theory concerning the cell reproduction in a series of generations (omnis cellula e cellula). Cell communities or ensembles integrated by the signaling systems established in prokaryotes and protists and functioning in multicellular organisms including mammals are considered as the structural and functional unit of a multicellular organism. The cell is an elementary unit of life and basis of organism development and functioning. At the same time, the adult organism is not just a totality of cells. Multinucleated cells in some tissues, syncytial structure, and structural-functional units of organs are adaptations for optimal functioning of the multicellular organism and manifestations of cell-cell communications in development and definitive functioning. The cell theory was supplemented and developed by studies on cell-cell communications; however, these studies do not question the main generalizations of the theory.

Developing Elementary Science PCK for Teacher Education: Lessons Learned from a Second Grade Partnership

NASA Astrophysics Data System (ADS)

Bradbury, Leslie U.; Wilson, Rachel E.; Brookshire, Laura E.

2017-06-01

In this self-study, two science educators partnered with two elementary teachers to plan, implement, and reflect on a unit taught in second grade classrooms that integrated science and language arts. The researchers hoped to increase their pedagogical content knowledge (PCK) for elementary science teaching so that they might use their experiences working in an elementary context to modify their practices in their elementary science method instruction. The research question guiding the study was: What aspects of our PCK for elementary science teaching do we as science educators develop by co-planning, co-teaching, and reflecting with second grade teachers? Data include transcripts of planning meetings, oral reflections about the experience, and videos of the unit being enacted. Findings indicate that managing resources for science teaching, organizing students for science learning, and reflecting on science teaching were themes prevalent in the data. These themes were linked to the model of PCK developed by Park and Oliver (Research in Science Education, 38, 261-284, 2008) and demonstrate that we developed PCK for elementary science teaching in several areas. In our discussion, we include several proposed changes for our elementary science methods course based on the outcomes of the study.

Personal goals as predictors of intended classroom goals: comparing elementary and secondary school pre-service teachers.

PubMed

Daniels, Lia M; Frenzel, Anne C; Stupnisky, Robert H; Stewart, Tara L; Perry, Raymond P

2013-09-01

The literature documents fewer classroom mastery goal structures in secondary school compared to elementary. However, little is known about how personal achievement goals may influence classroom goal structures. This is especially true at the level of pre-service teachers. Our objective was to investigate if pre-service teachers' personal goals predicted their intended classroom goal structures. Participants were 125 elementary and 175 secondary school pre-service teachers from two Western Canadian universities. Structural equation modelling was used to examine if the structural relationships and latent means of personal and intended classroom goal structures differed for elementary and secondary school pre-service teachers. The results revealed that personal goals predicted the goal structures that pre-service teachers intended to establish; however, the relationships and means differed between elementary and secondary school pre-service teachers. Specifically, personal mastery-approach goals positively predicted classroom mastery goals much more strongly at the elementary than the secondary level. Furthermore, elementary pre-service teachers had significantly higher latent mean scores on personal mastery-approach goals than their secondary counterparts. It seems possible that the currently documented differences between classroom goal structures noted for elementary compared to secondary school may be based on the personal goals endorsed as pre-service teachers. The results are further discussed in terms of alignment with research on practising teachers' personal and classroom goals and implications for teacher education. © 2012 The British Psychological Society.

Structural and dynamic characteristics in monolayer square ice.

PubMed

Zhu, YinBo; Wang, FengChao; Wu, HengAn

2017-07-28

When water is constrained between two sheets of graphene, it becomes an intriguing monolayer solid with a square pattern due to the ultrahigh van der Waals pressure. However, the square ice phase has become a matter of debate due to the insufficient experimental interpretation and the slightly rhomboidal feature in simulated monolayer square-like structures. Here, we performed classical molecular dynamics simulations to reveal monolayer square ice in graphene nanocapillaries from the perspective of structure and dynamic characteristics. Monolayer square-like ice (instantaneous snapshot), assembled square-rhombic units with stacking faults, is a long-range ordered structure, in which the square and rhombic units are assembled in an order of alternative distribution, and the other rhombic unit forms stacking faults (polarized water chains). Spontaneous flipping of water molecules in monolayer square-like ice is intrinsic and induces transformations among different elementary units, resulting in the structural evolution of monolayer square ice in dynamics. The existence of stacking faults should be attributed to the spontaneous flipping behavior of water molecules under ambient temperature. Statistical averaging results (thermal average positions) demonstrate the inherent square characteristic of monolayer square ice. The simulated data and insight obtained here might be significant for understanding the topological structure and dynamic behavior of monolayer square ice.

Reframing conceptual physics: Improving relevance to elementary education and sonography majors

NASA Astrophysics Data System (ADS)

LaFazia, David Gregory

This study outlines the steps taken to reframe the Waves and Periodicity unit within a conceptual physics course. Beyond this unit reframing process, this paper explores the activities that made up the reframed unit and how each was developed and revised. The unit was reframed to improve relevance of the activities to the Elementary Education and Diagnostic Medical Sonography majors who make up the bulk of the course roster. The unit was reframed around ten design principles that were built on best practices from the literature, survey responses, and focused interviews. These principles support the selection of a biology-integrated themed approach to teaching physics. This is done through active and highly kinesthetic learning across three realms of human experience: physical, social, and cognitive. The unit materials were designed around making connections to students' future careers while requiring students to take progressively more responsibility in activities and assessments. Several support strategies are employed across these activities and assessments, including an energy-first, guided-inquiry approach to concept scaffolding and accommodations for diverse learners. Survey responses were solicited from physics instructors experienced with this population, Elementary Education and Sonography program advisors, and curriculum design, learning strategies, and educational technology experts. The reframed unit was reviewed by doctoral-level science education experts and revised to further improve the depth and transparency with which the design principles reframe the unit activities. The reframed unit contains a full unit plan, lesson plans, and full unit materials. These include classroom and online activities, assessments, and templates for future unit and lesson planning. Additional supplemental materials are provided to support Elementary Education and Sonography students and program advisors and also further promote the reframed unit materials and design principles. The unit is designed to be educative in nature and serves as a model for the reframing of other units. A number of the design principles are highly transdisciplinary in nature and may be applied for reframing instructional units outside of the physics and science disciplines.

PubMed

Ahuja, Dheeraj; Kaushik, Anupama; Chauhan, Ghanshyam S

2017-04-01

In this work lignin was extracted from waste jute bags using soda cooking method and effect of varying alkali concentration and pH on yield, purity, structure and thermal degradation of lignin were studied. The Lignin yield, chemical composition and purity were assessed using TAPPI method and UV-vis spectroscopy. Yield and purity of lignin ranged from 27 to 58% and 50-94%, respectively for all the samples and was maximum for 8% alkali concentration and at pH 2 giving higher thermal stability. Chemical structure, thermal stability and elementary analysis of lignin were studied using FTIR, H NMR, thermo gravimetric analysis (TGA) and Elemental analyzer. FTIR and H NMR results showed that core structure of lignin starts breaking beyond 10% alkali concentration. S/G ratio shows the dominance of Syringyl unit over guaiacyl unit.

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

NASA Astrophysics Data System (ADS)

Bering, E. A.; Ramsey, J.; Smith, H.; Boyko, B. S.; Peck, S.; Arcenaux, W. H.

2005-05-01

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.

Exploring the evolution of protein function in Archaea.

PubMed

Goncearenco, Alexander; Berezovsky, Igor N

2012-05-30

Despite recent progress in studies of the evolution of protein function, the questions what were the first functional protein domains and what were their basic building blocks remain unresolved. Previously, we introduced the concept of elementary functional loops (EFLs), which are the functional units of enzymes that provide elementary reactions in biochemical transformations. They are presumably descendants of primordial catalytic peptides. We analyzed distant evolutionary connections between protein functions in Archaea based on the EFLs comprising them. We show examples of the involvement of EFLs in new functional domains, as well as reutilization of EFLs and functional domains in building multidomain structures and protein complexes. Our analysis of the archaeal superkingdom yields the dominating mechanisms in different periods of protein evolution, which resulted in several levels of the organization of biochemical function. First, functional domains emerged as combinations of prebiotic peptides with the very basic functions, such as nucleotide/phosphate and metal cofactor binding. Second, domain recombination brought to the evolutionary scene the multidomain proteins and complexes. Later, reutilization and de novo design of functional domains and elementary functional loops complemented evolution of protein function.

Exergaming impact on physical activity and interest in elementary school children.

PubMed

Sun, Haichun

2012-06-01

In this study, I explored the impact of exergaming on in-class physical activity (PA) and motivation in physical education. Elementary children participated in a 4-week exergaming unit and a 4-week fitness unit. A t test showed the children's in-class PA in the exergaming unit was significantly lower than in the fitness unit. Results also indicated that students' situational interest in exergaming was significantly higher than in the fitness unit at the beginning and end of instruction. Children's interest declined significantly in both units and at the same rate. The evidence suggests that exergames may have strong motivational power but it is premature to claim they will increase physical activity enough for children to receive health benefits in physical education.

Modeling discrete combinatorial systems as alphabetic bipartite networks: theory and applications.

PubMed

Choudhury, Monojit; Ganguly, Niloy; Maiti, Abyayananda; Mukherjee, Animesh; Brusch, Lutz; Deutsch, Andreas; Peruani, Fernando

2010-03-01

Genes and human languages are discrete combinatorial systems (DCSs), in which the basic building blocks are finite sets of elementary units: nucleotides or codons in a DNA sequence, and letters or words in a language. Different combinations of these finite units give rise to potentially infinite numbers of genes or sentences. This type of DCSs can be represented as an alphabetic bipartite network (ABN) where there are two kinds of nodes, one type represents the elementary units while the other type represents their combinations. Here, we extend and generalize recent analytical findings for ABNs derived in [Peruani, Europhys. Lett. 79, 28001 (2007)] and empirically investigate two real world systems in terms of ABNs, the codon gene and the phoneme-language network. The one-mode projections onto the elementary basic units are also studied theoretically as well as in real world ABNs. We propose the use of ABNs as a means for inferring the mechanisms underlying the growth of real world DCSs.

Beyond Columnar Organization: Cell Type- and Target Layer-Specific Principles of Horizontal Axon Projection Patterns in Rat Vibrissal Cortex

PubMed Central

Narayanan, Rajeevan T.; Egger, Robert; Johnson, Andrew S.; Mansvelder, Huibert D.; Sakmann, Bert; de Kock, Christiaan P.J.; Oberlaender, Marcel

2015-01-01

Vertical thalamocortical afferents give rise to the elementary functional units of sensory cortex, cortical columns. Principles that underlie communication between columns remain however unknown. Here we unravel these by reconstructing in vivo-labeled neurons from all excitatory cell types in the vibrissal part of rat primary somatosensory cortex (vS1). Integrating the morphologies into an exact 3D model of vS1 revealed that the majority of intracortical (IC) axons project far beyond the borders of the principal column. We defined the corresponding innervation volume as the IC-unit. Deconstructing this structural cortical unit into its cell type-specific components, we found asymmetric projections that innervate columns of either the same whisker row or arc, and which subdivide vS1 into 2 orthogonal [supra-]granular and infragranular strata. We show that such organization could be most effective for encoding multi whisker inputs. Communication between columns is thus organized by multiple highly specific horizontal projection patterns, rendering IC-units as the primary structural entities for processing complex sensory stimuli.

Zakharchenya, Boris P.; Korenev, Vladimir L.

2005-06-01

The view of a ferromagnetic-semiconducting hybrid structure as a single tunable system is presented. Based on an analysis of existing experiments it is shown that, contrary to a 'common sense', a nonmagnetic semiconductor is capable of playing an important role in controlling ferromagnetism. Magnetic properties of a hybrid (the hysteresis loop and the spatial orientation of magnetization) can be tuned both optically and electrically by utilizing semiconductor—making the hybrid an electronic-write-in and electronic-read-out elementary storage unit.

Determining the value of the fine-structure constant from a current balance: Getting acquainted with some upcoming changes to the SI

NASA Astrophysics Data System (ADS)

Davis, Richard S.

2017-05-01

The revised International System of Units (SI), expected to be approved late in 2018, has implications for physics pedagogy. The ampere definition, which dates from 1948, will be replaced by a definition that fixes the numerical value of the elementary charge e in coulombs. The kilogram definition, which dates from 1889, will be replaced by a definition that fixes the numerical value of the Planck constant h in joule seconds. Existing SI equations will be completely unaffected. However, there will be a largely negligible, but nevertheless necessary, change to published numerical factors relating SI electrical units to their corresponding units in the Gaussian and other CGS systems of units. The implications of the revised SI for electrical metrology are neatly illustrated by considering the interpretation of results obtained from a current balance in the present SI and in the revised SI.

Analysis of the project synthesis goal cluster orientation and inquiry emphasis of elementary science textbooks

NASA Astrophysics Data System (ADS)

Staver, John R.; Bay, Mary

The purpose of this descriptive study was to examine selected units of commonly used elementary science texts, using the Project Synthesis goal clusters as a framework for part of the examination. An inquiry classification scheme was used for the remaining segment. Four questions were answered: (1) To what extent do elementary science textbooks focus on each Project Synthesis goal cluster? (2) In which part of the text is such information found? (3) To what extent are the activities and experiments merely verifications of information already introduced in the text? (4) If inquiry is present in an activity, then what is the level of such inquiry?Eleven science textbook series, which comprise approximately 90 percent of the national market, were selected for analysis. Two units, one primary (K-3) and one intermediate (4-6), were selected for analysis by first identifying units common to most series, then randomly selecting one primary and one intermediate unit for analysis.Each randomly selected unit was carefully read, using the sentence as the unit of analysis. Each declarative and interrogative sentence in the body of the text was classified as: (1) academic; (2) personal; (3) career; or (4) societal in its focus. Each illustration, except those used in evaluation items, was similarly classified. Each activity/experiment and each miscellaneous sentence in end-of-chapter segments labelled review, summary, evaluation, etc., were similarly classified. Finally, each activity/experiment, as a whole, was categorized according to a four-category inquiry scheme (confirmation, structured inquiry, guided inquiry, open inquiry).In general, results of the analysis are: (1) most text prose focuses on academic science; (2) most remaining text prose focuses on the personal goal cluster; (3) the career and societal goal clusters receive only minor attention; (4) text illustrations exhibit a pattern similar to text prose; (5) text activities/experiments are academic in orientation, almost to the exclusion of other goal clusters; (6) end-of-chapter sentences are largely academic; (7) inquiry is absent or present only in limited forms in text activities/experiments; and (8) texts allocate only a minor portion of space to activities/experiments. Detailed findings are given as numeral, percentage, and decimal values. Discussion focuses on the implications of the results and a comparison of NSTA recommendations with the results of this analysis.

From inside the black box: Teacher perceptions of science instruction at the elementary level

NASA Astrophysics Data System (ADS)

Ferrini, Cynthia D.

Science education reform projects aimed at elementary school children arose in the 1960's. The most prevalent of these reforms utilized the inquiry, or hands-on, science method. Billions of dollars have been invested in these reforms. Yet, reports indicate that science is not being taught at the level one might expect in elementary schools. This research was an analysis of the problems and concerns teachers at one school district faced as they tried to implement and sustain elementary inquiry science instruction. The district chosen was a large suburban district in the Western United States. The population was ninety percent Caucasian with a slightly more ethnically diverse school population. This district was chosen because it had an elementary science program for over twenty years and had received national acclaim for that program. The district had a stable and homogeneous staff there was a low administrator and teacher turnover rate and the elementary teaching population was ninety percent Caucasian and ninety percent female. Interviews with administrators and teachers were conducted. Data were collected from focus groups of teachers and science partners. Observations of elementary science classroom instruction and professional development sessions were made. Results of this research indicated that one important key to elementary science reform rests in the hands of teachers. Once the door to the classroom is closed, the teacher can decide to teach or not to teach science. The findings of this research illustrate that teachers hold ideas about science and science instruction that are antithetical to some tenets of inquiry science. Until these ideas are addressed it will be difficult, if not impossible, to implement a systemic elementary inquiry science program. This study demonstrates that professional development for elementary teachers in science needs to change from a focus on the mechanical usage of individual units to a focus on teacher expectations for student achievement. Professional development for teachers in inquiry science must address the cognitive foundations for inquiry science and the benefits students derive from this educational approach. Institutions delivering pre-service training for elementary teachers in science must change the curriculum to reflect these needs.

This research describes the development process, psychometric analyses and part validation study of a theoretically-grounded Rasch-based instrument, the Nature of Science Instrument-Elementary (NOSI-E). The NOSI-E was designed to measure elementary students' understanding of the Nature of Science (NOS). Evidence is provided for three of the six validity aspects (content, substantive and generalizability) needed to support the construct validity of the NOSI-E. A future article will examine the structural and external validity aspects. Rasch modeling proved especially productive in scale improvement efforts. The instrument, designed for large-scale assessment use, is conceptualized using five construct domains. Data from 741 elementary students were used to pilot the Rasch scale, with continuous improvements made over three successive administrations. The psychometric properties of the NOSI-E instrument are consistent with the basic assumptions of Rasch measurement, namely that the items are well-fitting and invariant. Items from each of the five domains (Empirical, Theory-Laden, Certainty, Inventive, and Socially and Culturally Embedded) are spread along the scale's continuum and appear to overlap well. Most importantly, the scale seems appropriately calibrated and responsive for elementary school-aged children, the target age group. As a result, the NOSI-E should prove beneficial for science education research. As the United States' science education reform efforts move toward students' learning science through engaging in authentic scientific practices (NRC, 2011), it will be important to assess whether this new approach to teaching science is effective. The NOSI-E can be used as one measure of whether this reform effort has an impact.
Impact of an engineering design-based curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines

2016-01-01

Background: Elementary Science Education is struggling with multiple challenges. National and State test results confirm the need for deeper understanding in elementary science education. Moreover, national policy statements and researchers call for increased exposure to engineering and technology in elementary science education. The basic motivation of this study is to suggest a solution to both improving elementary science education and increasing exposure to engineering and technology in it. Purpose/Hypothesis: This mixed-method study examined the impact of an engineering design-based curriculum compared to an inquiry-based curriculum on fifth graders' content learning of simple machines. We hypothesize that the LEGO-engineering design unit is as successful as the inquiry-based unit in terms of students' science content learning of simple machines. Design/Method: We used a mixed-methods approach to investigate our research questions; we compared the control and the experimental groups' scores from the tests and interviews by using Analysis of Covariance (ANCOVA) and compared each group's pre- and post-scores by using paired t-tests. Results: Our findings from the paired t-tests show that both the experimental and comparison groups significantly improved their scores from the pre-test to post-test on the multiple-choice, open-ended, and interview items. Moreover, ANCOVA results show that students in the experimental group, who learned simple machines with the design-based unit, performed significantly better on the interview questions. Conclusions: Our analyses revealed that the design-based Design a people mover: Simple machines unit was, if not better, as successful as the inquiry-based FOSS Levers and pulleys unit in terms of students' science content learning.

Students attending schools play an important role in the transmission of influenza. In this study, we present a social network analysis of contacts among 1,828 students in eight different schools in urban and suburban areas in and near Pittsburgh, Pennsylvania, United States of America, including elementary, elementary-middle, middle, and high schools. We collected social contact information of students who wore wireless sensor devices that regularly recorded other devices if they are within a distance of 3 meters. We analyzed these networks to identify patterns of proximal student interactions in different classes and grades, to describe community structure within the schools, and to assess the impact of the physical environment of schools on proximal contacts. In the elementary and middle schools, we observed a high number of intra-grade and intra-classroom contacts and a relatively low number of inter-grade contacts. However, in high schools, contact networks were well connected and mixed across grades. High modularity of lower grades suggests that assumptions of homogeneous mixing in epidemic models may be inappropriate; whereas lower modularity in high schools suggests that homogenous mixing assumptions may be more acceptable in these settings. The results suggest that interventions targeting subsets of classrooms may work better in elementary schools than high schools. Our work presents quantitative measures of age-specific, school-based contacts that can be used as the basis for constructing models of the transmission of infections in schools. PMID:26978780

Xu, Jie; Wu, Tao; Peng, Chuang; Adegbite, Stephen

2017-09-01

The geometric Plateau border model for closed cell polyurethane foam was developed based on volume integrations of approximated 3D four-cusp hypocycloid structure. The tetrahedral structure of convex struts was orthogonally projected into 2D three-cusp deltoid with three central cylinders. The idealized single unit strut was modeled by superposition. The volume of each component was calculated by geometric analyses. The strut solid fraction f s and foam porosity coefficient δ were calculated based on representative elementary volume of Kelvin and Weaire-Phelan structures. The specific surface area Sv derived respectively from packing structures and deltoid approximation model were put into contrast against strut dimensional ratio ɛ. The characteristic foam parameters obtained from this semi-empirical model were further employed to predict foam thermal conductivity.

Instructional support and implementation structure during elementary teachers' science education simulation use

NASA Astrophysics Data System (ADS)

Gonczi, Amanda L.; Chiu, Jennifer L.; Maeng, Jennifer L.; Bell, Randy L.

2016-07-01

This investigation sought to identify patterns in elementary science teachers' computer simulation use, particularly implementation structures and instructional supports commonly employed by teachers. Data included video-recorded science lessons of 96 elementary teachers who used computer simulations in one or more science lessons. Results indicated teachers used a one-to-one student-to-computer ratio most often either during class-wide individual computer use or during a rotating station structure. Worksheets, general support, and peer collaboration were the most common forms of instructional support. The least common instructional support forms included lesson pacing, initial play, and a closure discussion. Students' simulation use was supported in the fewest ways during a rotating station structure. Results suggest that simulation professional development with elementary teachers needs to explicitly focus on implementation structures and instructional support to enhance participants' pedagogical knowledge and improve instructional simulation use. In addition, research is needed to provide theoretical explanations for the observed patterns that should subsequently be addressed in supporting teachers' instructional simulation use during professional development or in teacher preparation programs.

The Potential Impacts of Upcoming High-Stakes Testing on the Teaching of Science in Elementary Classrooms

NASA Astrophysics Data System (ADS)

Pringle, Rose M.; Martin, Sarah Carrier

2005-09-01

In 1983, the National Commission on Excellence in Education in the United States issued a report called A Nation at Risk: The Imperative for Educational Reform. This report and other policy initiatives such as the No Child Left Behind Legislation recommended that the individual states institute assessments to hold schools accountable. This research explored the potential impact of impending standardised testing on teaching science in elementary schools in one school district in Florida. We explored the teachers' concerns about the upcoming high-stakes tests in science, possible impact on their curriculum and what changes, if any, will be made in the approach to science teaching and learning in their classrooms. As the teachers look toward the implementation of high-stakes testing in science, they have recognised the need to teach science. This recognition is not borne out of the importance of science learning for elementary school children, but rather out of fear of failure and the effects of tangible rewards or punishments that accompany high-stakes testing. In anticipation, the teachers are preparing to align their teaching to the science standards while aggressively searching for test preparatory materials. Schools are also involved in professional development and structural changes to facilitate teaching of science.

Ohri-Vachaspati, Punam; Turner, Lindsey; Chaloupka, Frank J

2012-06-01

Dietary intake among children in the United States falls short of national recommendations. Schools can play an important role in improving children's preferences and food consumption patterns. The US Department of Agriculture's Fresh Fruit and Vegetable Program (FFVP) aims to improve children's nutrient intake patterns by offering fresh fruits and vegetables as snacks outside the reimbursable meals programs in elementary schools that serve large numbers of low-income children. Using a nationally representative sample of public elementary schools, this cross-sectional study investigated FFVP participation patterns among schools by demographic and school characteristics. Further, the study investigated the association between FFVP participation and availability of fresh fruits, salads, and vegetables at lunch as reported by school administrators and foodservice staff. Data collected via a mail-back survey from 620 public elementary schools participating in the National School Lunch Program during 2009-2010 were analyzed. Almost 70% of the FFVP-participating schools had a majority of students (>50%) eligible for free and reduced-cost meals. Participating in US Department of Agriculture Team Nutrition Program and having a registered dietitian or a nutritionist on staff were significantly associated with FFVP participation. Based on the results from logistic regression analyses schools participating in the FFVP were significantly more likely (odds ratio 2.07; 95% CI 1.12 to 3.53) to serve fresh fruit during lunch meals. Slightly >25% of public elementary schools across the United States participated in the FFVP, and participation was associated with healthier food availability in school lunches.

To examine the availability of competitive foods in elementary schools. Nationally representative mail-back survey. United States public and private elementary schools during the 2006-2007, 2007-2008, 2008-2009, and 2009-2010 school years. Survey respondents at 2647 public and 1205 private elementary schools. The availability of foods offered in competitive venues. Elementary school students' access to foods in competitive venues on campus (vending machines, school stores, snack bars, or à la carte lines) remained constant over time. As of the 2009-2010 school year, approximately half of all public and private elementary school students could purchase foods in 1 or more competitive venues on campus. Sugary foods were available to almost all students with access to competitive foods on campus. Public elementary school students in the South had more access to competitive food venues and greater availability of salty and sweet products in those venues compared with students in other parts of the country; however, they also had greater availability of healthier foods, such as fruits and vegetables. Many elementary school students can purchase competitive foods on campus. Most students with access to competitive venues could purchase sweet products, but healthier foods were less widely available.

Transforming a Traditional Inquiry-Based Science Unit into a STEM Unit for Elementary Pre-service Teachers: A View from the Trenches

NASA Astrophysics Data System (ADS)

Schmidt, Matthew; Fulton, Lori

2016-04-01

The need to prepare students with twenty-first-century skills through STEM-related teaching is strong, especially at the elementary level. However, most teacher education preparation programs do not focus on STEM education. In an attempt to provide an exemplary model of a STEM unit, we used a rapid prototyping approach to transform an inquiry-based unit on moon phases into one that integrated technology in a meaningful manner to develop technological literacy and scientific concepts for pre-service teachers (PSTs). Using qualitative case study methodology, we describe lessons learned related to the development and implementation of a STEM unit in an undergraduate elementary methods course, focusing on the impact the inquiry model had on PSTs' perceptions of inquiry-based science instruction and how the integration of technology impacted their learning experience. Using field notes and survey data, we uncovered three overarching themes. First, we found that PSTs held absolutist beliefs and had a need for instruction on inquiry-based learning and teaching. Second, we determined that explicit examples of effective and ineffective technology use are needed to help PSTs develop an understanding of meaningful technology integration. Finally, the rapid prototyping approach resulted in a successful modification of the unit, but caused the usability of our digital instructional materials to suffer. Our findings suggest that while inquiry-based STEM units can be implemented in existing programs, creating and testing these prototypes requires significant effort to meet PSTs' learning needs, and that iterating designs is essential to successful implementation.
Effect of structure in problem based learning on science teaching efficacy beliefs and science content knowledge of elementary preservice teachers

NASA Astrophysics Data System (ADS)

Sasser, Selena Kay

This study examined the effects of differing amounts of structure within the problem based learning instructional model on elementary preservice teachers' science teaching efficacy beliefs, including personal science teaching efficacy and science teaching outcome expectancy, and content knowledge acquisition. This study involved sixty (60) undergraduate elementary preservice teachers enrolled in three sections of elementary science methods classes at a large Midwestern research university. This study used a quasi-experimental nonequivalent design to collect and analyze both quantitative and qualitative data. Participants completed instruments designed to assess science teaching efficacy beliefs, science background, and demographic data. Quantitative data from pre and posttests was obtained using the science teaching efficacy belief instrument-preservice (STEBI-B) developed by Enochs and Riggs (1990) and modified by Bleicher (2004). Data collection instruments also included a demographic questionnaire, an analytic rubric, and a structured interview; both created by the researcher. Quantitative data was analyzed by conducting ANCOVA, paired samples t-test, and independent samples t-test. Qualitative data was analyzed using coding and themes. Each of the treatment groups received the same problem scenario, one group experienced a more structured PBL setting, and one group experienced a limited structure PBL setting. Research personnel administered pre and posttests to determine the elementary preservice teachers' science teaching efficacy beliefs. The results show elementary preservice teachers'science teaching efficacy beliefs can be influence by the problem based learning instructional model. This study did not find that the amount of structure in the form of core ideas to consider and resources for further research increased science teaching efficacy beliefs in this sample. Results from the science content knowledge rubric indicated that structure can increase science content knowledge in this sample. Qualitative data from the tutor, fidelity raters, and interviews indicated the participants were excited about the problem and were interested in the science content knowledge related to the problem. They also indicated they were motivated to continue informal study in the problem area. Participants indicated, during the interview, their initial frustration with the lack of knowledge gained from the tutor; however, indicated this led to more learning on their part. This study will contribute to the overall knowledge of problem based learning and its structures, science teaching efficacy beliefs of elementary preservice teachers, and to current teaching and learning practices.
Self-organization of network dynamics into local quantized states

DOE PAGES

Nicolaides, Christos; Juanes, Ruben; Cueto-Felgueroso, Luis

2016-02-17

Self-organization and pattern formation in network-organized systems emerges from the collective activation and interaction of many interconnected units. A striking feature of these non-equilibrium structures is that they are often localized and robust: only a small subset of the nodes, or cell assembly, is activated. Understanding the role of cell assemblies as basic functional units in neural networks and socio-technical systems emerges as a fundamental challenge in network theory. A key open question is how these elementary building blocks emerge, and how they operate, linking structure and function in complex networks. Here we show that a network analogue of themore » Swift-Hohenberg continuum model—a minimal-ingredients model of nodal activation and interaction within a complex network—is able to produce a complex suite of localized patterns. Thus, the spontaneous formation of robust operational cell assemblies in complex networks can be explained as the result of self-organization, even in the absence of synaptic reinforcements.« less

Mechanism of the formation of the RecA-ssDNA nucleoprotein filament structure: a coarse-grained approach.

PubMed

Mukherjee, Goutam; Pal, Arumay; Levy, Yaakov

2017-11-21

In prokaryotes, the RecA protein catalyzes the repair and strand exchange of double-stranded DNA. RecA binds to single-stranded DNA (ssDNA) and forms a presynaptic complex in which the protein polymerizes around the ssDNA to form a right-handed helical nucleoprotein filament structure. In the present work, the mechanism for the formation of the RecA-ssDNA filament structure is modeled using coarse-grained molecular dynamics simulations. Information from the X-ray structure was used to model the protein itself but not its interactions; the interactions between the protein and the ssDNA were modeled solely by electrostatic, aromatic, and repulsive energies. For the present study, the monomeric, dimeric, and trimeric units of RecA and 4, 8, and 11 NT-long ssDNA, respectively, were studied. Our results indicate that monomeric RecA is not sufficient for nucleoprotein filament formation; rather, dimeric RecA is the elementary binding unit, with higher multimeric units of RecA facilitating filament formation. Our results reveal that loop region flexibility at the primary binding site of RecA is essential for it to bind the incoming ssDNA, that the aromatic residues present in the loop region play an important role in ssDNA binding, and that ATP may play a role in guiding the ssDNA by changing the electrostatic potential of the RecA protein.

Teacher collaboration and elementary science teaching: Using action research as a tool for instructional leadership

NASA Astrophysics Data System (ADS)

Roberts, Sara Hayes

The primary purpose of this action research study was to explore an elementary science program and find ways to support science education as an administrator of an elementary school. The study took place in a large suburban school system in the southeastern United States. Seven teachers at a small rural school volunteered to participate in the study. Each participant became an active member of the research by determining what changes needed to take place and implementing the lessons in science. The study was also focused on teacher collaboration and how it influenced the science instruction. The data collected included two interviews, ten observations of science lessons, the implementation of four science units, and informal notes from planning sessions over a five month period. The questions that guided this study focused on how teachers prepare to teach science through active learning and how instruction shifts due to teacher collaboration. Teachers were interviewed at the beginning of the study to gain the perceptions of the participants in the areas of (a) planning, (b) active learning, (c) collaboration, and (d) teaching science lessons. The teachers and principal then formed a research team that determined the barriers to teaching science according to the Standards, designed units of study using active learning strategies, and worked collaboratively to implement the units of study. The action research project reviewed the National Science Education Standards, the theory of constructivism, active learning and teacher collaboration as they relate to the actions taken by a group of teachers in an elementary school. The evidence from this study showed that by working together collaboratively and overcoming the barriers to teaching science actively, teachers feel more confident and knowledgeable about teaching the concepts.

A network view on psychiatric disorders: network clusters of symptoms as elementary syndromes of psychopathology.

PubMed

Goekoop, Rutger; Goekoop, Jaap G

2014-01-01

The vast number of psychopathological syndromes that can be observed in clinical practice can be described in terms of a limited number of elementary syndromes that are differentially expressed. Previous attempts to identify elementary syndromes have shown limitations that have slowed progress in the taxonomy of psychiatric disorders. To examine the ability of network community detection (NCD) to identify elementary syndromes of psychopathology and move beyond the limitations of current classification methods in psychiatry. 192 patients with unselected mental disorders were tested on the Comprehensive Psychopathological Rating Scale (CPRS). Principal component analysis (PCA) was performed on the bootstrapped correlation matrix of symptom scores to extract the principal component structure (PCS). An undirected and weighted network graph was constructed from the same matrix. Network community structure (NCS) was optimized using a previously published technique. In the optimal network structure, network clusters showed a 89% match with principal components of psychopathology. Some 6 network clusters were found, including "Depression", "Mania", "Anxiety", "Psychosis", "Retardation", and "Behavioral Disorganization". Network metrics were used to quantify the continuities between the elementary syndromes. We present the first comprehensive network graph of psychopathology that is free from the biases of previous classifications: a 'Psychopathology Web'. Clusters within this network represent elementary syndromes that are connected via a limited number of bridge symptoms. Many problems of previous classifications can be overcome by using a network approach to psychopathology.
A discrete fibre dispersion method for excluding fibres under compression in the modelling of fibrous tissues.

PubMed

Li, Kewei; Ogden, Ray W; Holzapfel, Gerhard A

2018-01-01

Recently, micro-sphere-based methods derived from the angular integration approach have been used for excluding fibres under compression in the modelling of soft biological tissues. However, recent studies have revealed that many of the widely used numerical integration schemes over the unit sphere are inaccurate for large deformation problems even without excluding fibres under compression. Thus, in this study, we propose a discrete fibre dispersion model based on a systematic method for discretizing a unit hemisphere into a finite number of elementary areas, such as spherical triangles. Over each elementary area, we define a representative fibre direction and a discrete fibre density. Then, the strain energy of all the fibres distributed over each elementary area is approximated based on the deformation of the representative fibre direction weighted by the corresponding discrete fibre density. A summation of fibre contributions over all elementary areas then yields the resultant fibre strain energy. This treatment allows us to exclude fibres under compression in a discrete manner by evaluating the tension-compression status of the representative fibre directions only. We have implemented this model in a finite-element programme and illustrate it with three representative examples, including simple tension and simple shear of a unit cube, and non-homogeneous uniaxial extension of a rectangular strip. The results of all three examples are consistent and accurate compared with the previously developed continuous fibre dispersion model, and that is achieved with a substantial reduction of computational cost. © 2018 The Author(s).

Examining curricular coherence in an exemplary elementary school program.

PubMed

Ennis, Catherine D

2008-03-01

A coherent curriculum is characterized by visible connections between purposes and experiences so that students acknowledge the content's immediate value. This study examined an exemplary elementary physical education curriculum for coherence components. Research questions examined the role of coherence in connecting and engaging students meaningfully in physical education. Observations and interviews were conducted to collect qualitative data in one program for 22 weeks. Data were analyzed using open, axial, and selective coding. Results described two units, Balls Skills, leading to modified basketball, and Scooter City, a theme-based unit emphasizing student choice and responsibility. Students reported that both units were enjoyable. Although the Balls Skills unit was well planned, taught, and managed, some students commented that the skill and games content was valuable only in basketball. In the Scooter City unit, students identified numerous connections to out-of-school activities that enhanced content value. Comparisons with Beane's coherence criteria suggested that students valued Scooter City based on concrete connections to their lived experiences.

Bonding-restricted structure search for novel 2D materials with dispersed C2 dimers.

PubMed

Zhang, Cunzhi; Zhang, Shunhong; Wang, Qian

2016-07-12

Currently, the available algorithms for unbiased structure searches are primarily atom-based, where atoms are manipulated as the elementary units, and energy is used as the target function without any restrictions on the bonding of atoms. In fact, in many cases such as nanostructure-assembled materials, the structural units are nanoclusters. We report a study of a bonding-restricted structure search method based on the particle swarm optimization (PSO) for finding the stable structures of two-dimensional (2D) materials containing dispersed C2 dimers rather than individual C atoms. The C2 dimer can be considered as a prototype of nanoclusters. Taking Si-C, B-C and Ti-C systems as test cases, our method combined with density functional theory and phonon calculations uncover new ground state geometrical structures for SiC2, Si2C2, BC2, B2C2, TiC2, and Ti2C2 sheets and their low-lying energy allotropes, as well as their electronic structures. Equally important, this method can be applied to other complex systems even containing f elements and other molecular dimers such as S2, N2, B2 and Si2, where the complex orbital orientations require extensive search for finding the optimal orientations to maximize the bonding with the dimers, predicting new 2D materials beyond MXenes (a family of transition metal carbides or nitrides) and dichalcogenide monolayers.

Too young for rainforests? The impact of a rainforest curriculum on elementary students' affective responses to nature

NASA Astrophysics Data System (ADS)

Matteson, Kathryn Alice

A theory relating to children's affective responses to education about large-scale, distant environmental issues has become fairly widely accepted among environmental educators. The theory is encapsulated in the term "ecophobia," coined by David Sobel in Beyond Ecophobia (1996). According to this notion, elementary school children may become fearful of, or dissociated from, nature as they receive little direct exposure to nature and as they learn about distant environmental issues such as rainforest depletion. However, this seems a conflation of two discrete factors (lack of exposure to nature and education about distant environmental issues) that should be examined separately. Although children's exposure to nature has been studied, there appears to be no scientific research that examines elementary school students' affective responses to nature following education about distant environmental issues. This study endeavors to fill the apparent gap by measuring 4th graders' affective responses to nature following a unit on tropical rainforests. Deforestation represents a "distant" environmental issue that is thought to cause fear of, or dissociation from, nature among elementary school students. This quasi-experimental study involved a pretest, a posttest, and 150 4th grade participants in 8 classes. Students in all eight classes were administered a pretest questionnaire, inquiring about their affective responses to nature. Four classes then underwent a week-long unit on rainforests while four control group classes did not. All eight classes were then administered a posttest questionnaire. The data did not support the hypotheses that participants would feel more appreciative of nature and more empowered to protect nature following the rainforest unit. However, the data do support the hypotheses that the unit would not cause participants to feel increased fear of or dissociation from, nature. The data also suggest that greater amounts of time spent in nature were associated with greater appreciation of nature and less fear of nature. This research represents an initial effort to understand the developmental appropriateness of educating elementary school students about distant environmental issues. Further research on this topic is needed.

2016-04-01

Schools are in a unique position to ensure that all students meet the current physical activity (PA) recommendations. This study aimed to examine 1st to 3rd grade elementary students' accelerometer measured school day PA in the United States (U.S.) and Finland. The sample consisted of 200 students (107 girls, 93 boys; ages 6 to 8) and their school day PA was monitored with hip-worn ActiGraph GT3X+ accelerometers across a 5-day school week and the thresholds 100 and 2296 count per minute were used to separate sedentary time, light PA, and moderate-to-vigorous PA (MVPA). On an average school day, students were engaged in MVPA for 20.0 min in the U.S. and 24.1 min in Finland. Students' school-day MVPA was 9 to 16 minutes higher during physical education (PE) days compared with non-PE days (U.S: 25.8 vs. 16.6 min/day; Finland: 36.3 vs. 20.1 min/day). Girls had less MVPA and more sedentary time compared with boys in both samples. This study highlights both the role of PE and other school day physical activities in meeting PA guidelines. Policy measures are needed to change the structure of the school day and enhance PA to ensure that students meet the PA recommendations.
Curriculum coherence: A comparative analysis of elementary science content standards in People's Republic of China and the USA

NASA Astrophysics Data System (ADS)

Huang, Fang

This study examines elementary science content standards curriculum coherence between the People's Republic of China and the United States of America. Three aspects of curriculum coherence are examined in this study: topic inclusion, topic duration, and curriculum structure. Specifically this study centers on the following research questions: (1) What science knowledge is intended for elementary students in each country? (2) How long each topic stays in the curriculum? (3) How these topics sequence and connect with each other? (4) And finally, what is the implication for elementary science curriculum development? Four intended science curriculum frameworks were selected respectively for each country. A technique of General Topic Trace Mapping (GTTM) was applied to generate the composite science content standards out of the selected curriculum for each country. In comparison, the composite USA and Chinese elementary science content standards form a stark contrast: a bunch of broad topics vs. a focus on a set of key topics at each grade; an average of 3.4 year topic duration vs. an average of 1.68 year topic duration; a stress on connections among related ideas vs. a discrete disposition of related ideas; laundry list topic organization vs. hierarchical organization of science topics. In analyzing the interrelationships among these characteristics, this study reached implications for developing coherent science content standards: First, for the overall curriculum, the topic inclusion should reflect the logical and sequential nature of knowledge in science. Second, for each grade level, less, rather than more science topics should be focused. Third, however, it should be clarified that a balance should be made between curriculum breadth and depth by considering student needs, subject matter, and child development. Fourth, the topic duration should not be too long. The lengthy topic duration tends to undermine links among ideas as well as lead to superficial treatment of topics.

A Network View on Psychiatric Disorders: Network Clusters of Symptoms as Elementary Syndromes of Psychopathology

PubMed Central

Goekoop, Rutger; Goekoop, Jaap G.

2014-01-01

Introduction The vast number of psychopathological syndromes that can be observed in clinical practice can be described in terms of a limited number of elementary syndromes that are differentially expressed. Previous attempts to identify elementary syndromes have shown limitations that have slowed progress in the taxonomy of psychiatric disorders. Aim To examine the ability of network community detection (NCD) to identify elementary syndromes of psychopathology and move beyond the limitations of current classification methods in psychiatry. Methods 192 patients with unselected mental disorders were tested on the Comprehensive Psychopathological Rating Scale (CPRS). Principal component analysis (PCA) was performed on the bootstrapped correlation matrix of symptom scores to extract the principal component structure (PCS). An undirected and weighted network graph was constructed from the same matrix. Network community structure (NCS) was optimized using a previously published technique. Results In the optimal network structure, network clusters showed a 89% match with principal components of psychopathology. Some 6 network clusters were found, including "DEPRESSION", "MANIA", “ANXIETY”, "PSYCHOSIS", "RETARDATION", and "BEHAVIORAL DISORGANIZATION". Network metrics were used to quantify the continuities between the elementary syndromes. Conclusion We present the first comprehensive network graph of psychopathology that is free from the biases of previous classifications: a ‘Psychopathology Web’. Clusters within this network represent elementary syndromes that are connected via a limited number of bridge symptoms. Many problems of previous classifications can be overcome by using a network approach to psychopathology. PMID:25427156

Self-assembled structures of Gaussian nematic particles.

PubMed

Nikoubashman, Arash; Likos, Christos N

2010-03-17

We investigate the stable crystalline configurations of a nematic liquid crystal made of soft parallel ellipsoidal particles interacting via a repulsive, anisotropic Gaussian potential. For this purpose, we use genetic algorithms (GA) in order to predict all relevant and possible solid phase candidates into which this fluid can freeze. Subsequently we present and discuss the emerging novel structures and the resulting zero-temperature phase diagram of this system. The latter features a variety of crystalline arrangements, in which the elongated Gaussian particles in general do not align with any one of the high-symmetry crystallographic directions, a compromise arising from the interplay and competition between anisotropic repulsions and crystal ordering. Only at very strong degrees of elongation does a tendency of the Gaussian nematics to align with the longest axis of the elementary unit cell emerge.

The effect of pore-scale geometry and wettability on two-phase relative permeabilities within elementary cells

NASA Astrophysics Data System (ADS)

Bianchi Janetti, Emanuela; Riva, Monica; Guadagnini, Alberto

2017-04-01

We study the relative role of the complex pore space geometry and wettability of the solid matrix on the quantification of relative permeabilities characterizing steady state immiscible two-phase flow in porous media. We do so by considering elementary cells, which are typically employed in upscaling frameworks based on, e.g., homogenization or volume averaging. In this context one typically relies on the solution of pore-scale physics at a scale which is much smaller than that of an investigated porous system. Pressure-driven two-phase flow following simultaneous co-current injection of water and oil is numerically solved for a suite of regular and stochastically generated two-dimensional explicit elementary cells with fixed porosity and sharing main topological/morphological features. We show that relative permeabilities of the randomly generated elementary cells are significantly influenced by the formation of preferential percolation paths (principal pathways), giving rise to a strongly nonuniform distribution of fluid fluxes. These pathways are a result of the spatially variable resistance that the random pore structures exert on the fluid. The overall effect on relative permeabilities of the diverse organization of principal pathways, as driven by a given random realization at the scale of the unit cell, is significantly larger than that of the wettability of the host rock. In contrast to what can be observed for the random cells analyzed, relative permeabilities of regular cells display a clear trend with contact angle at the investigated scale. Our findings suggest the need to perform systematic upscaling studies in a stochastic context, to propagate the effects of uncertain pore space geometries to a probabilistic description of relative permeability curves at the continuum scale.

The minimal flow unit in near-wall turbulence

NASA Technical Reports Server (NTRS)

Jimeez, Javier; Moin, Parviz

1991-01-01

Direct numerical simulations of unsteady channel flow were performed at low to moderate Reynolds numbers on computational boxes chosen small enough so that the flow consists of a doubly periodic (in x and z) array of identical structures. The goal is to isolate the basic flow unit, to study its morphology and dynamics, and to evaluate its contribution to turbulence in fully developed channels. For boxes wider than approximately 100 wall units in the spanwise direction, the flow is turbulent, and the low-order turbulence statistics are in good agreement with experiments in the near-wall region. For a narrow range of widths below that threshold, the flow near only one wall remains turbulent, but its statistics are still in fairly good agreement with experimental data when scaled with the local wall stress. For narrower boxes only laminar solutions are found. In all cases, the elementary box contains a single low-velocity streak, consisting of a longitudinal strip on which a thin layer of spanwise vorticity is lifted away from the wall.

Attitudes of pre-service elementary teachers towards science: A cross-national study between the United States of America and Turkey

NASA Astrophysics Data System (ADS)

Buldu, Nihal

Preservice elementary teachers' attitudes toward science have been the subject of investigation by science educators for decades. Many of the recent attempts pertaining to preservice elementary teachers by science educators have focused on the effects of science method courses on the attitudes and relationships between attitudes and other variables. The research literature lacks studies that compare attitudes of preservice elementary teachers toward science across two or more nations. The current study investigated the attitudes of preservice elementary teachers toward science in the U.S. and Turkey in order to see if there is a difference between the U.S. and Turkish preservice elementary teachers' attitudes toward science, and to investigate whether variables such as gender and the grade the preservice teachers wish to teach make a difference in preservice elementary teachers' attitudes towards science. The sample consisted of 1144 preservice elementary teachers. Of the 1144 preservice elementary teachers for whom complete information is available, it is known that 371 preservice elementary teachers were from the U.S. and 773 were from Turkey. The attitudes of preservice elementary teachers in the U.S. and Turkey were assessed by the data gathered using Turkish and American Preservice Elementary Teachers Attitude Scale (TAPETAS). This scale is a revised version of the Modified Fennema Sherman Attitude Scale (Doepken, Lawsky, and Padwa, 1999). Results of the current study indicated that both U.S. and Turkish preservice elementary teachers had positive attitudes toward science. However, U.S. preservice elementary teachers had more confidence in science. They found science more useful than their Turkish peers. They had more positive attitudes towards their previous science teachers and were less likely to stereotype science as a male domain. There were not any significant differences between the U.S. preservice elementary teachers due to gender and the grade they wanted to teach. There were significant differences between the Turkish preservice teachers due to gender. Discussion of the findings, implications of the study and recommendations for further research were presented.

Understanding early elementary children's conceptual knowledge of plant structure and function through drawings.

PubMed

Anderson, Janice L; Ellis, Jane P; Jones, Alan M

2014-01-01

This study examined children's drawings to explain children's conceptual understanding of plant structure and function. The study explored whether the children's drawings accurately reflect their conceptual understanding about plants in a manner that can be interpreted by others. Drawing, survey, interview, and observational data were collected from 182 students in grades K and 1 in rural southeastern United States. Results demonstrated the children held a wide range of conceptions concerning plant structure and function. These young children held very simple ideas about plants with respect to both their structure and function. Consistent with the drawings, the interviews presented similar findings. © 2014 J. L.

Content Specificity of Expectancy Beliefs and Task Values in Elementary Physical Education

PubMed Central

Chen, Ang; Martin, Robert; Ennis, Catherine D.; Sun, Haichun

2015-01-01

The curriculum may superimpose a content-specific context that mediates motivation (Bong, 2001). This study examined content specificity of the expectancy-value motivation in elementary school physical education. Students’ expectancy beliefs and perceived task values from a cardiorespiratory fitness unit, a muscular fitness unit, and a traditional skill/game unit were analyzed using constant comparison coding procedures, multivariate analysis of variance, χ2, and correlation analyses. There was no difference in the intrinsic interest value among the three content conditions. Expectancy belief, attainment, and utility values were significantly higher for the cardiorespiratory fitness curriculum. Correlations differentiated among the expectancy-value components of the content conditions, providing further evidence of content specificity in the expectancy-value motivation process. The findings suggest that expectancy beliefs and task values should be incorporated in the theoretical platform for curriculum development based on the learning outcomes that can be specified with enhanced motivation effect.

We describe a 2 mg artificial elementary eye whose structure and functionality is inspired by compound eye ommatidia. Its optical sensitivity and electronic architecture are sufficient to generate the required signals for the measurement of local optic flow vectors in multiple directions. Multiple elementary eyes can be assembled to create a compound vision system of desired shape and curvature spanning large fields of view. The system configurability is validated with the fabrication of a flexible linear array of artificial elementary eyes capable of extracting optic flow over multiple visual directions. © 2015 The Author(s).
Bonding-restricted structure search for novel 2D materials with dispersed C2 dimers

PubMed Central

Zhang, Cunzhi; Zhang, Shunhong; Wang, Qian

2016-01-01

Currently, the available algorithms for unbiased structure searches are primarily atom-based, where atoms are manipulated as the elementary units, and energy is used as the target function without any restrictions on the bonding of atoms. In fact, in many cases such as nanostructure-assembled materials, the structural units are nanoclusters. We report a study of a bonding-restricted structure search method based on the particle swarm optimization (PSO) for finding the stable structures of two-dimensional (2D) materials containing dispersed C2 dimers rather than individual C atoms. The C2 dimer can be considered as a prototype of nanoclusters. Taking Si-C, B-C and Ti-C systems as test cases, our method combined with density functional theory and phonon calculations uncover new ground state geometrical structures for SiC2, Si2C2, BC2, B2C2, TiC2, and Ti2C2 sheets and their low-lying energy allotropes, as well as their electronic structures. Equally important, this method can be applied to other complex systems even containing f elements and other molecular dimers such as S2, N2, B2 and Si2, where the complex orbital orientations require extensive search for finding the optimal orientations to maximize the bonding with the dimers, predicting new 2D materials beyond MXenes (a family of transition metal carbides or nitrides) and dichalcogenide monolayers.

1. By comparison of electrophoretic mobilities of two different charged particles under the same conditions the net elementary electrostatic charge of one particle could be calculated when the charge of the other is known. 2. The electrophoretic mobility of human thyroxine - binding globulin does not depend upon the concentration of Tris - HCl buffer in the range 0.05 to 0.20 molar. The value of this mobility is 0.078 and 0.083 cm2 vol(-1) hour(-1) at pH 7.0 and 8.6, respectively. 3. The net elementary electrostatic charge of the human thyroxine - binding globulin appears to be approximately 22 negative elementary electrostatic units in mild alkaline solutions.
Shape-tailored polymer colloids on the road to become structural motifs for hierarchically organized materials.

PubMed

Plüisch, Claudia Simone; Wittemann, Alexander

2013-12-01

Anisometric polymer colloids are likely to behave differently when compared with centrosymmetric particles. Their study may not only shine new light on the organization of matter; they may also serve as building units with specific symmetries and complexity to build new materials from them. Polymer colloids of well-defined complex geometries can be obtained by packing a limited number of spherical polymer particles into clusters with defined configurations. Such supracolloidal architectures can be fabricated at larger scales using narrowly dispersed emulsion droplets as templates. Assemblies built from at least two different types of particles as elementary building units open perspectives in selective targeting of colloids with specific properties, aiming for mesoscale building blocks with tailor-made morphologies and multifunctionality. Polymer colloids with defined geometries are also ideal to study shape-dependent properties such as the diffusion of complex particles. © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
Hydration of sulfonated polyimide membranes. I. Na + and NH +(C 2H 5) 3 homopolymers

NASA Astrophysics Data System (ADS)

Jamróz, Dorota; Maréchal, Yves

2004-05-01

Hydration of Na + and HN +(C 2H 5) 3 sulfonated polyimide membranes is probed by infrared spectrometry using a recently described method. These membranes consist of identical sulfonated repeat unit (homopolymers) and form a good starting point to study more elaborated membranes, composed of these units plus similar ones with no sulfonic groups (block copolymers). These latter membranes may be used in fuel cells and will be described in a forthcoming article. We first identify the bands of hydrophilic groups, which will be anchor points for hydration. We then define three 'elementary hydration spectra' onto which all hydration spectra can be decomposed. Their analysis allows us to measure the water uptake of these membranes as a function of the hygrometry of the ambient atmosphere and to determine the structures of the dried membranes and their hydration mechanisms in terms of chemical reactions.
The Focal Surface of the JEM-EUSO Instrument

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

Kawasaki, Y.; EUSO Team, ASI, RIKEN; Casolino, M.

The Extreme Universe Space Observatory on JEM/EF (JEM-EUSO) is a space mission to study extremely high-energy cosmic rays. The JEM-EUSO instrument is a wide-angle refractive telescope in the near-ultraviolet wavelength region which will be mounted to the International Space Station. Its goal is to measure time-resolved fluorescence images of extensive air showers in the atmosphere. In this paper we describe in detail the main features and technological aspects of the focal surface of the instrument. The JEM-EUSO focal surface is a spherically curved surface, with an area of about 4.5m{sup 2}. The focal surface detector is made of more thanmore » 5,000 multi-anode photomultipliers (MAPMTs). Current baseline is Hamamatsu R11265-03-M64. The approach to the focal surface detector is highly modular. Photo-Detector-Modules (PDM) are the basic units that drive the mechanical structure and data acquisition. Each PDM consists of 9 Elementary Cells (ECs). The EC, which is the basic unit of the MAPMT support structure and of the front-end electronics, contains 4 units of MAPMTs. In total, about 1,200 ECs or about 150 PDMs are arranged on the whole of the focal surface of JEM-EUSO.« less
A methodology to find the elementary landscape decomposition of combinatorial optimization problems.

PubMed

Chicano, Francisco; Whitley, L Darrell; Alba, Enrique

2011-01-01

A small number of combinatorial optimization problems have search spaces that correspond to elementary landscapes, where the objective function f is an eigenfunction of the Laplacian that describes the neighborhood structure of the search space. Many problems are not elementary; however, the objective function of a combinatorial optimization problem can always be expressed as a superposition of multiple elementary landscapes if the underlying neighborhood used is symmetric. This paper presents theoretical results that provide the foundation for algebraic methods that can be used to decompose the objective function of an arbitrary combinatorial optimization problem into a sum of subfunctions, where each subfunction is an elementary landscape. Many steps of this process can be automated, and indeed a software tool could be developed that assists the researcher in finding a landscape decomposition. This methodology is then used to show that the subset sum problem is a superposition of two elementary landscapes, and to show that the quadratic assignment problem is a superposition of three elementary landscapes.
Six-component semi-discrete integrable nonlinear Schrödinger system

NASA Astrophysics Data System (ADS)

Vakhnenko, Oleksiy O.

2018-01-01

We suggest the six-component integrable nonlinear system on a quasi-one-dimensional lattice. Due to its symmetrical form, the general system permits a number of reductions; one of which treated as the semi-discrete integrable nonlinear Schrödinger system on a lattice with three structural elements in the unit cell is considered in considerable details. Besides six truly independent basic field variables, the system is characterized by four concomitant fields whose background values produce three additional types of inter-site resonant interactions between the basic fields. As a result, the system dynamics becomes associated with the highly nonstandard form of Poisson structure. The elementary Poisson brackets between all field variables are calculated and presented explicitly. The richness of system dynamics is demonstrated on the multi-component soliton solution written in terms of properly parameterized soliton characteristics.

Dirac delta representation by exact parametric equations.. Application to impulsive vibration systems

NASA Astrophysics Data System (ADS)

Chicurel-Uziel, Enrique

2007-08-01

A pair of closed parametric equations are proposed to represent the Heaviside unit step function. Differentiating the step equations results in two additional parametric equations, that are also hereby proposed, to represent the Dirac delta function. These equations are expressed in algebraic terms and are handled by means of elementary algebra and elementary calculus. The proposed delta representation complies exactly with the values of the definition. It complies also with the sifting property and the requisite unit area and its Laplace transform coincides with the most general form given in the tables. Furthermore, it leads to a very simple method of solution of impulsive vibrating systems either linear or belonging to a large class of nonlinear problems. Two example solutions are presented.
Differences in school climate and student engagement in China and the United States.

PubMed

Bear, George G; Yang, Chunyan; Chen, Dandan; He, Xianyou; Xie, Jia-Shu; Huang, Xishan

2018-06-01

The purpose of this study was to examine differences between American and Chinese students in their perceptions of school climate and engagement in school, and in the relation between school climate and engagement. Confirmatory factor analyses were used to support the factor structure and measurement invariance of the two measures administered: The Delaware School Climate Survey-Student and the Delaware Student Engagement Scale. Differences in latent means were tested, and differences in relations between variables were examined using multilevel hierarchical linear modeling. Participants consisted of 3,176 Chinese and 4,085 American students, Grades 3-5, 7-8, and 10-12. Chinese students perceived school climate more favorably than American students, particularly beyond elementary school. Findings were more complex for student engagement. In elementary school, American students reported greater cognitive-behavioral and emotional engagement, and especially the former. In middle school and high school, Chinese students reported greater emotional engagement; however, no significant differences were found for cognitive-behavioral engagement. Most intriguing were results of multilevel hierarchical modeling that examined associations between school climate and student engagement: They were significant in American schools but not Chinese schools. Chinese students, compared with American students, perceived the climate of their schools more favorably, especially after elementary school. However, among Chinese students, their perceptions of school climate were unrelated to their self-reported engagement in school-school climate did not seem to matter as much.

The transfer of learning process: From an elementary science methods course to classroom instruction

NASA Astrophysics Data System (ADS)

Carter, Nina Leann

The purpose of this qualitative multiple-case study was to explore the transfer of learning process in student teachers. This was carried out by focusing on information learned from an elementary science methods and how it was transferred into classroom instruction during student teaching. Participants were a purposeful sampling of twelve elementary education student teachers attending a public university in north Mississippi. Factors that impacted the transfer of learning during lesson planning and implementation were sought. The process of planning and implementing a ten-day science instructional unit during student teaching was examined through lesson plan documentation, in-depth individual interviews, and two focus group interviews. Narratives were created to describe the participants' experiences as well as how they plan for instruction and consider science pedagogical content knowledge (PCK). Categories and themes were then used to build explanations applying to the research questions. The themes identified were Understanding of Science PCK, Minimalism, Consistency in the Teacher Education Program, and Emphasis on Science Content. The data suggested that the participants lack in their understanding of science PCK, took a minimalistic approach to incorporating science into their ten-day instructional units, experienced inconsistencies in the teacher education program, and encountered a lack of emphasis on science content in their field experience placements. The themes assisted in recognizing areas in the elementary science methods courses, student teaching field placements, and university supervision in need of modification.
Elementary teachers past experiences: A narrative study of the past personal and professional experiences of elementary teachers who use science to teach math and reading

NASA Astrophysics Data System (ADS)

Acre, Andrea M.

This qualitative study investigated the experiences of four elementary teachers who have elected to use science to teach math and reading/language arts in an attempt to identify what motivates them to do so. Identifying what experiences have motivated these teachers to go against the gain and teach elementary science in this current era of high-stakes tests is of the upmost importance given that science is being eliminated from the elementary curriculum and it is during the elementary years that students' nurture and develop their interest in science. Additionally, the United States is failing to produce enough college graduates in STEM areas to fill the thousands of STEM jobs each year. Through a review of the literature, the past trends and current trends of elementary science education were explored as well as teacher training. Furthermore, the literature reviewed inquiry teaching which is considered to be the most effective teaching method when teaching science at any level. Using John Dewey's Interest and Effort Relationship Theory and the Self-Determination Motivation Theory to guide this study, there were five prominent themes which emerged from the reconstructed stories of the four teachers: positive experiences with science, neutral/negative experiences with science, seeks meaningful professional development, influence and support from others, and regret/wants to do more.

Analysis of 2D hyperbolic metamaterial dispersion by elementary excitation coupling

NASA Astrophysics Data System (ADS)

Vaianella, Fabio; Maes, Bjorn

2016-04-01

Hyperbolic metamaterials are examined for many applications thanks to the large density of states and extreme confinement of light they provide. For classical hyperbolic metal/dielectric multilayer structures, it was demon- strated that the properties originate from a specific coupling of the surface plasmon polaritons between the metal/dielectric interfaces. We show a similar analysis for 2D hyperbolic arrays of square (or rectangular) silver nanorods in a TiO2 host. In this case the properties derive from a specific coupling of the plasmons carried by the corners of the nanorods. The dispersion can be seen as the coupling of single rods for a through-metal connection of the corners, as the coupling of structures made of four semi-infinite metallic blocks separated by dielectric for a through-dielectric connection, or as the coupling of two semi-infinite rods for a through-metal and through-dielectric situation. For arrays of small square nanorods the elementary structure that explains the dispersion of the array is the single rod, and for arrays of large square nanorods it is four metallic corners. The medium size square nanorod case is more complicated, because the elementary structure can be one of the three basic designs, depending on the frequency and symmetry of the modes. Finally, we show that for arrays of rectangular nanorods the dispersion is explained by coupling of the two coupled rod structure. This work opens the way for a better understanding of a wide class of metamaterials via their elementary excitations.
The Economic Effect of Competition in the Air Transportation Industry

NASA Technical Reports Server (NTRS)

Hubbard, H. B.

1972-01-01

The air transportation industry has been described as a highly-competitive, regulated oligopoly or as a price-regulated cartel with blocked entry, resulting in excessive service and low load factors. The current structure of the industry has been strongly influenced by the hypotheses that increased levels of competition are desirable per se, and that more competing carriers can be economically supported in larger markets, in longer haul markets, with lower unit costs, and with higher fare levels. An elementary application of competition/game theory casts doubt on the validity of these hypotheses, but rather emphasizes the critical importance of the short-term non-variable costs in determining economic levels of competition.
Elementary GLOBE: Inquiring About the Earth System Through Elementary Student Investigations

NASA Astrophysics Data System (ADS)

Henderson, S.; Hatheway, B.; Gardiner, L.; Gallagher, S.

2006-12-01

Elementary GLOBE was designed to introduce K-4 students to the study of Earth System Science (ESS). Elementary GLOBE forms an instructional unit comprised of five modules that address ESS and interrelated subjects including weather, hydrology, seasons, and soils. Each Elementary GLOBE module contains a science based storybook, classroom learning activities that complement the science content covered in each book, and teacher's notes. The storybooks explore a component of the Earth system and the associated classroom learning activities provide students with a meaningful introduction to technology, a basic understanding of the methods of inquiry, and connection to math and literacy skills. The science content in the books and activities serves as a springboard to GLOBE's scientific protocols. All Elementary GLOBE materials are freely downloadable (www.globe.gov/elementaryglobe) The use of science storybooks with elementary students has proven to be an effective practice in exposing students to science content while providing opportunities for students to improve their reading, writing, and oral communication skills. The Elementary GLOBE storybooks portray kids asking questions about the natural world, doing science investigations, and exploring the world around them. Through the storybook characters, scientific inquiry is modeled for young learners. The associated learning activities provide opportunities for students to practice science inquiry and investigation skills, including observation, recording, measuring, etc. Students also gain exposure and increase their comfort with different tools that scientists use. The learning activities give students experiences with asking questions, conducting scientific investigations, and scientific journaling. Elementary GLOBE fills an important niche in K-4 instruction. The international GLOBE Program brings together students, teachers, and scientists with the basic goals of increasing scientific understanding of the Earth, supporting improved student achievement in science and math, and enhancing environmental awareness. NASA provides the primary source of funding for GLOBE.
Introducing Ergonomics in Two US Elementary Schools

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

Bennett, C L; Tien, D

2003-06-25

The increasing presence of computers and other forms of information and communications technology (ICT) in schools has raised concerns in the United States (US) and elsewhere. Children are using computers more than any other age group in the US. It is not known whether early intensive use of ICT predisposes children to future injury. Ergonomics is not included in state curriculum standards or requirements but can be supported by some of the existing standards. Some who believe that children are better off being educated early about ergonomics are taking action to bring ergonomics into elementary and secondary schools. This papermore » describes the process used to introduce ergonomics into two elementary schools in two different states by initiators with two different roles.« less
