    Our study addresses the need for new approaches to prepare novice elementary teachers to teach both science and engineering, and for new tools to measure how well those approaches are working. This in particular would inform the teacher educators of the extent to which novice teachers are developing expertise in facilitating their students' engineering design work. One important dimension to measure is novice teachers' abilities to notice the substance of student thinking and to respond in productive ways. This teacher noticing is particularly important in science and engineering education, where students' initial, idiosyncratic ideas and practices influence the likelihood that particular instructional strategies will help them learn. This paper describes evidence of validity and reliability for the Video Case Diagnosis (VCD) task, a new instrument for measuring pre-service elementary teachers' engineering teaching responsiveness. To complete the VCD, participants view a 6-min video episode of children solving an engineering design problem, describe in writing what they notice about the students' science ideas and engineering practices, and propose how a teacher could productively respond to the students. The rubric for scoring VCD responses allowed two independent scorers to achieve inter-rater reliability. Content analysis of the video episode, systematic review of literature on science and engineering practices, and solicitation of external expert educator responses establish content validity for VCD. Field test results with three different participant groups who have different levels of engineering education experience offer evidence of construct validity.

    The quality of problem representation is critical for developing students' problem-solving abilities in problem-based learning (PBL). This study investigates preclinical students' experience with standardized patients (SPs) as a problem representation method compared to using video cases in PBL. A cohort of 99 second-year preclinical students from Inje University College of Medicine (IUCM) responded to a Likert scale questionnaire on their learning experiences after they had experienced both video cases and SPs in PBL. The questionnaire consisted of 14 items with eight subcategories: problem identification, hypothesis generation, motivation, collaborative learning, reflective thinking, authenticity, patient-doctor communication, and attitude toward patients. The results reveal that using SPs led to the preclinical students having significantly positive experiences in boosting patient-doctor communication skills; the perceived authenticity of their clinical situations; development of proper attitudes toward patients; and motivation, reflective thinking, and collaborative learning when compared to using video cases. The SPs also provided more challenges than the video cases during problem identification and hypotheses generation. SPs are more effective than video cases in delivering higher levels of authenticity in clinical problems for PBL. The interaction with SPs engages preclinical students in deeper thinking and discussion; growth of communication skills; development of proper attitudes toward patients; and motivation. Considering the higher cost of SPs compared with video cases, SPs could be used most advantageously during the preclinical period in the IUCM curriculum.

    Thomas Balslev, a paediatric neurologist and educational researcher, defended his thesis on 24 November 2011. The thesis included five published papers, and investigated learning with authentic, brief patient video cases. With analysis of a video case in a small group, learning processes and sharing of knowledge was intensely stimulated. Small group discussion and subsequent listening to an expert's think-aloud were particularly effective approaches to enhance diagnostic accuracy among non-experts. In a descriptive study, expertise-related differences during analysis of patient video cases were characterized, and in a controlled study, different types of visual modelling were tested.

  15. Investigating elementary education and physical therapy majors' perceptions of an inquiry-based physics content course

    Science.gov (United States)

    Hilton, John Martin

    This study investigates why physical therapy assistant majors engage and perform better than elementary education majors in an inquiry-based conceptual physics course at Mid-Atlantic Community College. The students from each major are demographically similar, both courses are similar in depth and structure, and each course supports the students' program. However, there is an observed difference in the levels of engagement with the curriculum and performance on writing-based assessments between the two groups. To explore possible explanations for the difference, I examine students' affinity for science, their beliefs about the nature of science and scientific knowledge in the classroom, and their perception of the usefulness of science to their program. During semi-structured interviews, students from both majors displayed nearly identical weak affinities for science, epistemological beliefs, and uncertainty about the usefulness of the class. However, the physical therapy majors' ability to see the relevance of the physics course experience to their program enhanced their interest and motivation. In contrast, the elementary education students do not see connections between the course and their program, and do not see a purpose for their learning of physics content. To improve the program, I propose a two-pronged approach - designing a faded-scaffolded-inquiry approach for both classes, and developing a field-based/seminar class for the elementary education majors. The scaffolded inquiry will help both groups develop better orientations toward lab activities, and the structured observations and reflection will help the elementary group connect the material to their program.

  20. Performance-based classrooms: A case study of two elementary teachers of mathematics and science

    Science.gov (United States)

    Jones, Kenneth W.

    This case study depicts how two elementary teachers develop classrooms devoted to performance-based instruction in mathematics and science. The purpose is to develop empirical evidence of classroom practices that leads to a conceptual framework about the nature of performance-based instruction. Performance-based assessment and instruction are defined from the literature to entail involving students in tasks that are complex and engaging, requiring them to apply knowledge and skills in authentic contexts. In elementary mathematics and science, such an approach emphasizes problem solving, exploration, inquiry, and reasoning. The body of the work examines teacher beliefs, curricular orientations, instructional strategies, assessment approaches, management and organizational skills, and interpersonal relationships. The focus throughout is on those aspects that foster student performance in elementary mathematics and science. The resulting framework describes five characteristics that contribute to performance-based classrooms: a caring classroom community, a connectionist learning theory, a thinking and doing curriculum, diverse opportunities for learning, and ongoing assessment, feedback, and adjustment. The conclusion analyzes factors external to the classroom that support or constrain the development of performance-based classrooms and discusses the implications for educational policy and further research.

    Full Text Available This study aims to design a science learning program based on the local wisdom and apply it in elementary school. Mixed method research was use to gain the significance improvement from the design. There were 35 elementary science teachers from 16 elementary schools chosen by using purposive random sampling. The previous research revealed that there are about 80% of the teachers who were recognized the local wisdoms in their environment, but none of them have a capability to use it as a part of their science program in the classroom. To overcome this constrain, Review(R, Task(T, Solution(S, Reflection(R, and Evaluation(E design was proposed in elementary school science learning. By implementing the design in two elementary schools, 11 positive characters expected were indicated from students’ performance. But characters of honest, disciplined, conscientious, diligent, careful, responsibility, and caring environment, are most significant. Tujuan dari penelitian ini adalah mengembangkan desain pembelajaran sains berbasis kearifan lokal pada tingkat sekolah dasar.

    Science.gov (United States)

    Choi, Sanghee

    This study examined inservice elementary teachers' beliefs and practical knowledge toward inquiry-based science instruction and the influence of an inquiry-based elementary science course on teachers' beliefs and practical knowledge regarding inquiry. The 14 elementary teachers completed a three-credit elementary science methods course that emphasizes teaching science as inquiry. Both quantitative and qualitative data were collected using pretest and posttest surveys, and an intensive case study. The findings showed that the teachers' beliefs and practical knowledge about inquiry-based science instruction were clearly influenced by the inquiry-based elementary science course. The participant teachers constructed fairly positive beliefs and practical knowledge that promoted inquiry-instruction throughout this course. Moreover, they improved their knowledge and skills of conducting inquiry in their own science lessons. The majority of teachers successfully practiced inquiry-instruction in teaching their science lessons. Some of the teachers in this study exhibited small or modest changes in their practice of inquiry-instruction. To successfully translate inquiry-instruction in the classroom, a teacher must possess strong beliefs, knowledge, and expertise about inquiry. While the majority of these teachers had never been previously exposed to inquiry-instruction before this course, they expressed that they would continue to use more inquiry-instruction in their classroom at the end of the course. The teachers identified the following constraints that would prevent them from promoting inquiry in the classroom: time, effort, and collaborative support from experts. From the results of this study, it is important to underlie that teachers' beliefs could be used to predict their use of inquiry in their science lessons. If teachers really believe in something, then they are more likely to act accordingly and adopt new teaching practices as their own. It is recommended that

    Background Chronic exposure to well water arsenic (As) remains a major rural health challenge in Bangladesh and some other developing countries. Many mitigation programs have been implemented to reduce As exposure, although evaluation studies for these efforts are rare in the literature. Objectives In this study we estimated associations between a school-based intervention and various outcome measures of As mitigation. Methods We recruited 840 children from 14 elementary schools in Araihazar, Bangladesh. Teachers from 7 schools were trained on an As education curriculum, whereas the remaining 7 schools without any training formed the control group. Surveys, knowledge tests, and well-water testing were conducted on 773 children both at baseline and postintervention follow-up. Urine samples were collected from 210 children from 4 intervention schools and the same number of children from 4 control schools. One low-As ( Bangladesh standard of 50 μg/L) and significantly improved As knowledge attributable to the intervention after controlling for potential confounders. Conclusions These findings offer strong evidence that school-based intervention can effectively reduce As exposure in Bangladesh by motivating teachers, children, and parents.

  1. Simulation of DNAPL migration in heterogeneous translucent porous media based on estimation of representative elementary volume

    Science.gov (United States)

    Wu, Ming; Wu, Jianfeng; Wu, Jichun

    2017-10-01

    When the dense nonaqueous phase liquid (DNAPL) comes into the subsurface environment, its migration behavior is crucially affected by the permeability and entry pressure of subsurface porous media. A prerequisite for accurately simulating DNAPL migration in aquifers is then the determination of the permeability, entry pressure and corresponding representative elementary volumes (REV) of porous media. However, the permeability, entry pressure and corresponding representative elementary volumes (REV) are hard to determine clearly. This study utilizes the light transmission micro-tomography (LTM) method to determine the permeability and entry pressure of two dimensional (2D) translucent porous media and integrates the LTM with a criterion of relative gradient error to quantify the corresponding REV of porous media. As a result, the DNAPL migration in porous media might be accurately simulated by discretizing the model at the REV dimension. To validate the quantification methods, an experiment of perchloroethylene (PCE) migration is conducted in a two-dimensional heterogeneous bench-scale aquifer cell. Based on the quantifications of permeability, entry pressure and REV scales of 2D porous media determined by the LTM and relative gradient error, different models with different sizes of discretization grid are used to simulate the PCE migration. It is shown that the model based on REV size agrees well with the experimental results over the entire migration period including calibration, verification and validation processes. This helps to better understand the microstructures of porous media and achieve accurately simulating DNAPL migration in aquifers based on the REV estimation.

  2. The effect of site-based preservice experiences on elementary science teaching self-efficacy beliefs

    Science.gov (United States)

    Wingfield, Mary E.

    Current reform in science education has focused on the need for improvement of preservice teacher training (National Science Education Standards, 1996). As a situation specific construct (Bandura, 1977), self-efficacy studies have been conducted to investigate factors that impact preservice teachers' sense of confidence as it relates to their ability to become successful science teachers. This descriptive study identified factors in the site based experiences that affected preservice elementary teachers' self-efficacy as measured by the Science Teaching Efficacy Belief Instrument (STEBL-B) (Enochs and Riggs, 1990). The sample consisted of the entire population of undergraduate elementary preservice teachers in the site based teacher education program during the fall semester of 1997 at a large south central urban university. The 131 paired, pretest posttests of the entire STEBL-B and the two constructs were analyzed for significance in mean score gains. Results of the paired t test yielded a t value of 11.52 which was significant at p Bandura identified as sources of information used to determine self-efficacy. These include performance accomplishments through authentic teaching experiences, vicarious experiences through observation of the site based teachers, and verbal persuasion and physiological states from feedback given by the university coordinators. The majority of these preservice teachers started the semester with a negative attitude toward teaching science, but ended the semester with a positive view of themselves as effective science teachers in the future.

    Gado, Issaou

    The Republic of Benin (West Africa) undertook a nationwide curriculum reform that put an emphasis on inquiry-based instructional practices. Little, if any, research has been conducted to explore factors that could be related to teachers' orientation toward inquiry instructional practices. The purpose of this research study was to investigate factors and concerns that determine Benin elementary school teachers' orientation toward the use of inquiry-based instruction in the teaching of science. The study followed a naturalistic inquiry methodology combining a correlational ex post facto design and an observational case-study design. The theory of Planned Behavior was the conceptual framework used to design the study. Two hundred (N = 200) elementary school teachers and three (n = 3) case study participants were purposively selected. Data was gathered via the Revised Science Attitude Scale (Thompson & Shrigley, 1986), the Science Teachers' Ideological Preference Scale (Jones & Harty, 1978), open-ended questions, interviews, and classroom observations using audiorecorders, videorecorders, and the researcher-contextualized version of the Observational System for the Analysis of Classroom Instruction (Hough, 1966). Qualitative and quantitative data provided a deeper understanding of participants' responses. Quantitative measures indicated that Benin elementary school teachers have positive attitudes toward school science, significant positive orientation toward both inquiry-based instruction and traditional non inquiry-based instruction, and higher orientation toward inquiry-based instruction than traditional non inquiry-based instruction. Attitude toward handling materials for investigations was found to significantly contribute to the prediction of participants' inquiry orientation. Qualitative analyses of participants' responses indicated that the expectations of educational leaders, individual motivation to comply with the program, a perceived control of the

    2017-02-01

    Mannheimia succiniciproducens, a capnophilic gram-negative rumen bacterium, has been employed for the efficient production of succinic acid. Although M. succiniciproducens metabolism was previously studied using a genome-scale metabolic model, more metabolic characteristics are to be understood. To this end, elementary mode analysis accompanied with clustering ('EMC' analysis) is used to gain further insights on metabolic characteristics of M. succiniciproducens allowing efficient succinic acid production. Elementary modes (EMs) generated from the central carbon metabolic network of M. succiniciproducens are clustered to systematically analyze succinic acid production routes. Based on the results of EMC analysis, zwf gene is identified as a novel overexpression target for the improved succinic acid production. This gene is overexpressed in a previously constructed succinic acid-overproducing M. succiniciproducens LPK7 strain. Heterologous NADPH-dependent mdh is later intuitively selected for overexpression to synergistically improve succinic acid production by utilizing abundant NADPH pool mediated by the overexpressed zwf. The LPK7 strains co-expressing mdh alone and both zwf and mdh genes are subjected to fed-batch fermentation to better examine their succinic acid production performances. Strategies of EMC analysis will be useful for further metabolic engineering of M. succiniciproducens and other microorganisms to improve production of succinic acid and other chemicals of interest.

    Full Text Available This study investigated the relationship between eating behavior and childhood overweight among population-based elementary schoolchildren in Japan. Data was collected from fourth graders (9 or 10 years of age from Ina Town, Saitama Prefecture, Japan from 1999 to 2009. Information about subjects’ sex, age, and lifestyle, including eating behaviors (eating until full and chewing thoroughly, was obtained using a self-administered questionnaire, and height and weight were measured directly. Overweight was determined according to the definition established by the International Obesity Task Force. Data from 4027 subjects (2079 boys and 1948 girls were analyzed. Chewing thoroughly was associated with a significantly decreased odds ratio (OR for being overweight, whereas eating until full significantly increased the OR for being overweight (OR: 1.50, 95% confidence interval: 1.16–1.94 among boys. However, eating until full was not associated with a significantly increased OR for being overweight among the group that reported chewing thoroughly, whereas it was associated with a significantly increased OR for being overweight (2.02, 1.38–2.94 among boys who did not chew thoroughly. In conclusion, eating until full or not chewing thoroughly was associated with being overweight among elementary schoolchildren. Results of this study suggest that chewing thoroughly may be an avenue to explore childhood overweight prevention efforts.

    The Social Cognitive Theory (SCT) is a widely used model for developing elementary nutrition education programs; however, few instruments are available to assess the impact of such programs on the main constructs of the SCT. The purposes of this study were: 1) to develop and validate a SCT-based survey instrument that focuses on knowledge, behavior, and self-efficacy for fifth grade students; 2) to assess the relationships between knowledge, behavior, and self-efficacy; and 3) to assess knowledge, behavior, and self-efficacy for healthy eating among the fifth grade students. A 40-item instrument was developed and validated using content validity and tested among 98 fifth grade students for internal consistency reliability. Relationships between knowledge, behavior, and self-efficacy were assessed using Pearson Correlation Coefficients. Differences in behavior and knowledge scores between children with high and low self-efficacy were examined using t-test. Cronbach's alphas for self-efficacy (0.70) and behavior (0.71) subscales of the survey were acceptable, although lower for knowledge (0.56). Summary scores for self-efficacy and behaviors were positively correlated (r = 0.40, P = 0.0001); however, summary knowledge scores were not associated with self-efficacy (r = 0.02, P = 0.88) or behavior scores (r = 0.14, P = 0.23). Participants with high self-efficacy also had significantly higher scores on consuming fruits (P = 0.0009) and dairy products (P = 0.009), eating breakfast (P = 0.008), helping plan family meals (P = 0.0006) and total behaviors for healthy-eating (P = 0.001) compared to those with low self-efficacy. In addition, approximately two thirds of the fifth grade students reported that they did not eat any fruits or vegetables or ate them only once on a typical day. The developed instrument is a reliable and useful tool to assess SCT-based elementary nutrition education programs, particularly for self

    Lewis, Felecia J.

    The nature and purpose of this study was to examine the self-efficacy of teachers who use an inquiry-based science program to provide authentic experiences within the elementary school setting. It is essential to explore necessary improvements to bring about effective science education. Using a mixed methods study, the researcher conducted interviews with elementary teachers from five elementary schools within the same school district. The interviews focused on the teachers' experiences with inquiry-based science and their perceptions of quality science instruction. The Teachers' Sense of Efficacy Scale was used to collect quantitative data regarding the teachers' perception of instructional practice and student engagement. The study revealed that limited science content knowledge, inadequate professional development, and a low sense of self-efficacy have a substantial effect on teacher outcomes, instructional planning, and ability to motivate students to participate in inquiry-based learning. It will take a collective effort from administrators, teachers, parents, and students to discover ways to improve elementary science education.

  5. Revisiting the Authoritative-Dialogic Tension in Inquiry-Based Elementary Science Teacher Questioning

    Van Booven, Christopher D.

    2015-05-01

    Building on the 'questioning-based discourse analytical' framework developed by Singapore-based science educator and discourse analyst, Christine Chin, this study investigated the extent to which fifth-grade science teachers' use of questions with either an authoritative or dialogic orientation differentially restricted or expanded the quality and complexity of student responses in the USA. The author analyzed approximately 10 hours of classroom discourse from elementary science classrooms organized around inquiry-based science curricula and texts. Teacher questions and feedback were classified according to their dialogic orientation and contextually inferred structural purpose, while student understanding was operationalized as a dynamic interaction between cognitive process, syntacto-semantic complexity, and science knowledge type. The results of this study closely mirror Chin's and other scholars' findings that the fixed nature of authoritatively oriented questioning can dramatically limit students' opportunities to demonstrate higher order scientific understanding, while dialogically oriented questions, by contrast, often grant students the discursive space to demonstrate a greater breadth and depth of both canonical and self-generated knowledge. However, certain teacher questioning sequences occupying the 'middle ground' between maximal authoritativeness and dialogicity revealed patterns of meaningful, if isolated, instances of higher order thinking. Implications for classroom practice are discussed along with recommendations for future research.

    Elementary flux modes (EFMs) analysis constitutes a fundamental tool in systems biology. However, the efficient calculation of EFMs in genome-scale metabolic networks (GSMNs) is still a challenge. We present a novel algorithm that uses a linear programming-based tree search and efficiently enumerates a subset of EFMs in GSMNs. Our approach is compared with the EFMEvolver approach, demonstrating a significant improvement in computation time. We also validate the usefulness of our new approach by studying the acetate overflow metabolism in the Escherichia coli bacteria. To do so, we computed 1 million EFMs for each energetic amino acid and then analysed the relevance of each energetic amino acid based on gene/protein expression data and the obtained EFMs. We found good agreement between previous experiments and the conclusions reached using EFMs. Finally, we also analysed the performance of our approach when applied to large GSMNs. The stand-alone software TreeEFM is implemented in C++ and interacts with the open-source linear solver COIN-OR Linear program Solver (CLP). © The Author 2014. Published by Oxford University Press.

    Childhood obesity has become a national public health crisis in America. Physical inactivity and unhealthy eating behaviors may contribute to the childhood obesity epidemic. School-based healthy lifestyle interventions play a promising role in preventing and controlling childhood obesity. A comprehensive school-based healthy lifestyle intervention was implemented in 4 rural elementary schools in Kentucky. The intervention included 4 goals: improving physical education, health education, family/community involvement, and school wellness policies. Children's physical activity was assessed by pedometer, and nutrition was assessed by a previous day recall survey in January (baseline), February (t1), March (t2), April (t3), and May (t4) of 2011. The intervention had significant effects on increasing the percentages of children meeting physical activity (1% vs 5%, p school, grade, and age of the children. There was an increasing linear trend of physical activity and an increasing quadratic trend of nutrition over time among children. The intervention had beneficial effects in improving healthy behaviors among children. Further studies are needed to assess its long-term effects and cost-effectiveness. © 2014, American School Health Association.

    We report an adult patient presenting with choreiform movements 4 days after a large intravenous dose of cocaine. These movements were transitory and they normalized a week after admission. We believe this to be the first video case of acute chorea secondary to cocaine--a phenomenon popularly known as "crack dancing. " Cocaine abuse is associated with a wide range of movement disorders, including dystonia and exacerbation of Tourette's syndrome, multifocal tics, opsoclonus-myoclonus, choreiform movements, and stereotyped behavior known as "punding." Transient choreiform movements with a typical duration of 2 to 6 days are recognized by cocaine abusers themselves as crack dancing, but are infrequently reported. We present a video report of a patient with cocaine dependency and choreiform movements that normalized within a week of admission.

    2017-07-01

    In Indonesia, National Standardization Agency of Indonesia issued the Indonesian National Standard SNI 12-1015-1989 and SNI 12-1016-1989 to define the type of furniture dimensions that should be used by children in the elementary school level. This study aims to examine whether the current national standards for elementary school furniture dimensions issued by National Standardization Agency of Indonesia match the up-to-date Indonesian children's anthropometry. Two types of school furniture, small type (Type I, for grade 1-3) and large type (Type II, for grade 4-6), were evaluated in terms of seat height, seat depth, seat width and backrest height of a chair as well as the height and underneath height of a desk. 1146 students aged between 6 and 12 years old participated in the study. Seven anthropometric measurements were taken including stature, sitting shoulder height, sitting elbow height, popliteal height, buttock-popliteal length, knee height and hip breadth. Based on the standard school furniture dimensions and students' body dimensions, numbers of matches and mismatches between them were computed. Results indicated a substantial degree of mismatch between children's anthropometry and the standard dimensions of school furniture. The standard seat height was not appropriate for students among different grades with the mismatch percentage ranging from 63.4% to 96.7% for Type I and 72.7% to 99.0% for Type II. For desk height, the standard dimensions were not appropriate for students among different grades with the mismatch percentage ranging from 32.3% to 88.9% for Type I and 67.7% to 99.0% for Type II. Apparently, the current standards are out of date and need to be updated. Four different sizes of school furniture were hence proposed to accommodate the variation in students' anthropometry from Grade 1 to Grade 6. The proposed standard dimensions (PrS) of school furniture cover a slightly broader range of age and present a higher cumulative fit than the current

    The Society of Behavioral Medicine (SBM) urges elementary schools to provide children with ample opportunities to engage in physical activity during school hours. In addition to promoting overall child health, physical activity also supports academic achievement. In addition to improving their aerobic fitness, regular physical activity improves cognitive function, influences the brain, and improves mood in children. Better aerobic fitness and physical activity are associated with increased grade point averages and standardized test scores. Despite the documented relationship between physical activity, fitness, and academic achievement, few schools have implemented physical activity as a tool to improve academic performance. SBM recommends that elementary schools provide children with the recommended 60 min of moderate-to-vigorous physical activity during school hours. Further, SBM urges schools to work with the local school districts and state education departments to mandate minimum physical activity time for elementary school physical education.

    Creative drama activities designed to help children learn difficult science concepts were integrated into an inquiry-based elementary science program. Children (n = 38) in an upper elementary enrichment program at one primary school were the participants in this action research. The teacher-researcher taught students the Full Option Science System™ (FOSS) modules of sound (fourth grade) and solar energy (fifth grade) with the integration of creative drama activities in treatment classes. A 2 × 2 × (2) Mixed ANOVA was used to examine differences in the learning outcomes and attitudes toward science between groups (drama and non-drama) and grade levels (4th and 5th grades) over time (pre/post). Learning was measured using the tests included with the FOSS modules. A shortened version of the Three Dimension Elementary Science Attitude Survey measured attitudes toward science. Students in the drama treatment group had significantly higher learning gains ( F = 160.2, p students in the non-drama control group with students in grade four reporting significantly greater learning outcomes ( F = 14.3, p student attitudes toward science ( F = 7.5, p students when used as an active extension to the pre-existing inquiry-based science curriculum.

    With the continued threat of childhood obesity, many public health intervention efforts focus on school settings. The current study sought to document administrator attitudes regarding obesity and interest in improving relevant school practices (i.e., nutrition and physical activity) in elementary schools. Mail-back surveys were used to gather data from public and private elementary schools during the 2006-2007, 2007-2008, 2008-2009, and 2010-2011 school years. In each year, a different set of items pertaining to administrator attitudes was included. Numbers of responding schools annually ranged from 259 to 336 private schools, and from 578 to 748 public schools. The vast majority of elementary school administrators (>90%) agreed that schools can play a role in addressing childhood obesity, physical education improves a variety of academic outcomes, and they were interested in improving practices at their school. Concern about childhood obesity and perceiving that schools can play a role in addressing obesity were both associated with more interest in improving school practices. However, only one-third of administrators agreed that parents were interested in participating in improving nutrition and physical activity practices, suggesting opportunities for efforts to improve collaboration. Administrators are generally very supportive of school-based efforts to improve nutrition and physical activity practices and see the value in doing so. Given the amount of time children spend in school, schools are an essential venue for efforts to address childhood obesity.

    Full Text Available The education system in a country must be able to equip its young generation with sophisticated literacy skills, if they do not want to see individuals and their communities in poverty or poverty (PIRLS, 2007. The ability of literacy has become the center of attention has even become a crucial issue because of the ability of literacy related to the development of human resources in the future (PIRLS, 2007. This is because literacy skills are the key to success in school and the key to success to participate actively in the world of work, society, and politics. In the 2013 Curriculum, the competence expected from an SD / MI graduate is to have a productive and creative thinking and acting abstract and concrete. Writing is a productive action. Therefore, writing skills in Elementary School must continue to be nurtured and developed so that the expected graduate competence is achieved. Nevertheless, Alwasilah (2007 states that writing skills are the most neglected language skills in language education. This happens due to improper practice in writing lessons from elementary to university level. According to International Study of Achievement in Writen Composition (in Rahman, 2011, Indonesia is a country whose culture of writing and reading is still below average.

    2015-04-01

    The integration of engineering concepts and practices into elementary science education has become an emerging concern for science educators and practitioners, alike. Moreover, how children, specifically preadolescents (grades 1-5), engage in engineering design-based learning activities may help science educators and researchers learn more about children's earliest identification with engineering. The purpose of this study was to examine the extent to which engineering identity differed among preadolescents across gender and grade, when exposing students to engineering design-based science learning activities. Five hundred fifty preadolescent participants completed the Engineering Identity Development Scale (EIDS), a recently developed measure with validity evidence that characterizes children's conceptions of engineering and potential career aspirations. Data analyses of variance among four factors (i.e., gender, grade, and group) indicated that elementary school students who engaged in the engineering design-based science learning activities demonstrated greater improvements on the EIDS subscales compared to those in the comparison group. Specifically, students in the lower grade levels showed substantial increases, while students in the higher grade levels showed decreases. Girls, regardless of grade level and participation in the engineering learning activities, showed higher scores in the academic subscale compared to boys. These findings suggest that the integration of engineering practices in the science classroom as early as grade one shows potential in fostering and sustaining student interest, participation, and self-concept in engineering and science.

  6. A study of preservice elementary teachers enrolled in a discrepant-event-based physical science class

    Lilly, James Edward

    This research evaluated the POWERFUL IDEAS IN PHYSICAL SCIENCE (PIiPS) curriculum model used to develop a physical science course taken by preservice elementary teachers. The focus was on the evaluation of discrepant events used to induce conceptual change in relation to students' ideas concerning heat, temperature, and specific heat. Both quantitative and qualitative methodologies were used for the analysis. Data was collected during the 1998 Fall semester using two classes of physical science for elementary school teachers. The traditionally taught class served as the control group and the class using the PIiPS curriculum model was the experimental group. The PIiPS curriculum model was evaluated quantitatively for its influence on students' attitude toward science, anxiety towards teaching science, self efficacy toward teaching science, and content knowledge. An analysis of covariance was performed on the quantitative data to test for significant differences between the means of the posttests for the control and experimental groups while controlling for pretest. It was found that there were no significant differences between the means of the control and experimental groups with respect to changes in their attitude toward science, anxiety toward teaching science and self efficacy toward teaching science. A significant difference between the means of the content examination was found (F(1,28) = 14.202 and p = 0.001), however, the result is questionable. The heat and energy module was the target for qualitative scrutiny. Coding for discrepant events was adapted from Appleton's 1996 work on student's responses to discrepant event science lessons. The following qualitative questions were posed for the investigation: (1) what were the ideas of the preservice elementary students prior to entering the classroom regarding heat and energy, (2) how effective were the discrepant events as presented in the PIiPS heat and energy module, and (3) how much does the "risk taking

    Teachers need always to improve their competence because of the growth of science very rapidly as well as elementary school teachers. However, the provision of training will not produce an increase in the competence effectively if it is implemented without considering the needs and interests of teachers. The novelty factor which is highlighted through this research results, want to answer a problem, namely: how to conduct an effective training based on the needs and interests of teachers so that the effects of training can improve the competence of teachers? After going through research for two years with a qualitative approach which was preceded by a visit to the school and a series of interviews, treatment of training model, FGD, and triangulation then have been produced a way to implement of training based on the needs and interests of teachers. The training model includes face to face training which structured and scheduled according to the needs of elementary school teachers, followed by workshops, simulations, then the coach holds guidance in the classroom, and ends with reflections.

    Formulation of mathematical learning goals now is not only oriented on cognitive product, but also leads to cognitive process, which is probabilistic thinking. Probabilistic thinking is needed by students to make a decision. Elementary school students are required to develop probabilistic thinking as foundation to learn probability at higher level. A framework of probabilistic thinking of students had been developed by using SOLO taxonomy, which consists of prestructural probabilistic thinking, unistructural probabilistic thinking, multistructural probabilistic thinking and relational probabilistic thinking. This study aimed to analyze of probability task completion based on taxonomy of probabilistic thinking. The subjects were two students of fifth grade; boy and girl. Subjects were selected by giving test of mathematical ability and then based on high math ability. Subjects were given probability tasks consisting of sample space, probability of an event and probability comparison. The data analysis consisted of categorization, reduction, interpretation and conclusion. Credibility of data used time triangulation. The results was level of boy's probabilistic thinking in completing probability tasks indicated multistructural probabilistic thinking, while level of girl's probabilistic thinking in completing probability tasks indicated unistructural probabilistic thinking. The results indicated that level of boy's probabilistic thinking was higher than level of girl's probabilistic thinking. The results could contribute to curriculum developer in developing probability learning goals for elementary school students. Indeed, teachers could teach probability with regarding gender difference.

    Mindfulness-based interventions constitute a promising option to address anxiety and depression in elementary school students. This study evaluated the effect of a mindfulness-based intervention on anxiety and depression in elementary school students with a diagnosis of anxiety or depression disorder. A single-subject experimental A-B-A design was used. Participants were three elementary school students from grades three and four, along with their teacher. Anxiety and depression were measured on 10 occasions at baseline, during the intervention, and at follow-up. Primary hypotheses were tested using a univariate single case multilevel modeling strategy and visual analysis. Following intervention, 2 participants reported improvements on anxiety and depression, while their teachers reported deteriorating scores on these variables. Results from this n-of-1 trial design is consistent with other work suggesting caution with regard to the overall impact and efficacy of mindfulness-based interventions as a universal treatment option for youth. Future research is warranted.

    Problem-based learning in clinical practice has become an integral part of many professional preparation programs. This quasi-experimental study compared the effect of a specialized 90-hour field placement on elementary pre-service teachers' scientific reasoning and attitudes towards teaching STEM (science, technology, engineering, and math) subjects. A cohort of 53 undergraduate elementary education majors, concurrent to their enrollment in science and math methods classes, were placed into one of two clinical practice experiences: (a) a university-based, problem-based learning (PBL), STEM classroom, or (b) a traditional public school classroom. Group gain scores on the Classroom Test of Scientific Reasoning (CTSR) and the Teacher Efficacy and Attitudes Toward STEM Survey-Elementary Teachers (T-STEM) survey were calculated. A MANCOVA revealed that there was a significant difference in gain scores between the treatment and comparison groups' scientific reasoning (p = .011) and attitudes towards teaching STEM subjects (p = .004). The results support the hypothesis that the pre-service elementary teachers who experienced STEM mentoring in a PBL setting will have an increase in their scientific reasoning and produce positive attitudes towards teaching STEM subjects. In addition, the results add to the existing research suggesting that elementary pre-service teachers require significant academic preparation and mentored support in STEM content.

    Prevalence of childhood obesity is increasing significantly worldwide due to energy imbalance perhaps stemming from undesirable dietary behavior and physical activity level. The objective of the study was to examine the effects of physical activity level on nutritional status in elementary school students. The subjects were comprised of 287 elementary school students between 4th and 6th grades in Seoul, Korea. The level of physical activity was scored with a modified Godin leisure-time exercise questionnaire and was categorized as active, moderately active, and sedentary. Dietary intakes were obtained using a 24-hour food recall method. An analysis of variance (ANOVA) was conducted to test for global significant differences of nutrient intakes by physical activity level. Boys were more active than girls. Daily intakes of energy in moderately active boys were significantly higher than in the sedentary group, but intakes of calcium and iron in moderately active boys were lower than active boys. For girls, physical activity level did not affect nutrient density at all. Intakes of calcium, vitamin C, and folate for both boys and girls were below 50% of recommended intake. Physical activity did not affect nutrient density and our participants were exposed to nutritional imbalance. Therefore, the results suggest that nutrition education regarding balanced diet and optimum physical activity is required for children's health and growth.

    2016-01-01

    In 1974, the British physicist Stephen Hawking discovered that black holes have a characteristic temperature and are therefore capable of emitting radiation. Given the scientific importance of this discovery, there is a profuse literature on the subject. Nevertheless, the available literature ends up being either too simple, which does not convey the true physical significance of the issue, or too technical, which excludes an ample segment of the audience interested in science, such as physics teachers and their students. The present article seeks to remedy this shortcoming. It develops a simple and plausible argument that provides insight into the fundamental aspects of Hawking’s discovery, which leads to an approximate equation for the so-called Hawking temperature. The exposition is mainly intended for physics teachers and their students, and it only requires elementary algebra, as well as basic notions of Newtonian mechanics and quantum theory.

    Full Text Available This study used system dynamics method to investigate the factors affecting elementary school students’ BMI values. The construction of the dynamic model is divided into the qualitative causal loop and the quantitative system dynamics modeling. According to the system dynamics modeling, this study consisted of research on the four dimensions: student’s personal life style, diet-relevant parenting behaviors, advocacy and implementation of school nutrition education, and students’ peer interaction. The results of this study showed that students with more adequate health concepts usually have better eating behaviors and consequently have less chance of becoming obese. In addition, this study also verified that educational attainment and socioeconomic status of parents have a positive correlation with students’ amounts of physical activity, and nutrition education has a prominent influence on changing students’ high-calorie diets.

  17. Problem-based learning in elementary science methods: Exploring a format to prepare teachers for the 21st century

    Diercks, Rodney Wayne

    In order to meet the demands of the twenty-first century, national standards are calling for a new type of teacher to educate the future workforce. These standards include new methods for preparing teachers to address the challenging and complex issues facing educators and students. The Problem-Based Learning (PBL) method that has enjoyed success in medical training is showing promise in teacher education. The purpose of this blended case study was to describe the experiences of sixteen preservice teachers participating in a problem-based learning format while enrolled in a science methods class for elementary and middle school majors. The sixteen preservice teachers worked in collaborative groups mentored by inservice elementary and middle school teachers. The following five themes emerged regarding the effective implementation of PBL in teacher education: (1) The role of the instructor becomes one of facilitator; (2) The PBL process should be integrated throughout the entire course term; (3) The problems preservice teachers address must be challenging, personally relevant, and must build on their prior knowledge; (4) Students need to work collaboratively within the external conditions of safety, value, and freedom; (5) The solutions to the problems are most meaningful if students believe they can apply their solution to current and future classrooms. The Science Teacher Efficacy Belief Instrument (STEBI) was administered before and after the PBL experience. The results indicated an increase in the preservice teachers' self-efficacy in teaching science. The results from the STEBI support the qualitative findings of the study. The results of this study provide teacher education with a model for instruction that will help preservice teachers develop the skills and understandings of inquiry and inquiry-based methods needed to plan and teach successfully in their classrooms as well as collaborate and communicate with colleagues.

    Full Text Available Abstract Background Technological advances have enabled the widespread use of video cases via web-streaming and online download as an educational medium. The use of real subjects to demonstrate acute pathology should aid the education of health care professionals. However, the methodology by which this effect may be tested is not clear. Methods We undertook a literature review of major databases, found relevant articles relevant to using patient video cases as educational interventions, extracted the methodologies used and assessed these methods for internal and construct validity. Results A review of 2532 abstracts revealed 23 studies meeting the inclusion criteria and a final review of 18 of relevance. Medical students were the most commonly studied group (10 articles with a spread of learner satisfaction, knowledge and behaviour tested. Only two of the studies fulfilled defined criteria on achieving internal and construct validity. The heterogeneity of articles meant it was not possible to perform any meta-analysis. Conclusions Previous studies have not well classified which facet of training or educational outcome the study is aiming to explore and had poor internal and construct validity. Future research should aim to validate a particular outcome measure, preferably by reproducing previous work rather than adopting new methods. In particular cognitive processing enhancement, demonstrated in a number of the medical student studies, should be tested at a postgraduate level.

  5. A self-study of designing and implementing an inquiry-based chemistry course for elementary education majors

    2011-12-01

    This self-study examines my experiences with implementing an inquiry-based version of a chemistry course (Chemistry 299) designed for elementary education majors. The inquiry-based curriculum design and teaching strategies that I implement in Chemistry 299 is the focus of this study. Since my previous education and professional experiences were in the physical sciences, I position myself in this study as a scientist who engages in self-study as a form of professional development for the purpose of developing an inquiry-based curriculum and instructional practices. My research provides an inside perspective of the curriculum development process. This process involves implementing the inquiry-oriented ideas and knowledge I acquired in my graduate studies to design the curriculum and influence my teaching practice. My analysis of the curriculum and my instruction is guided by two questions: What are the strengths and weaknesses of the inquiry-based Chemistry 299 curriculum design? What does the process of developing my inquiry-based teaching practice entail and what makes is challenging? Schwab's (1973) The Practical 3: Translation into Curriculum serves as the theoretical framework for this study because of the emphasis Schwab places on combining theoretical and practical knowledge in the curriculum development process and because of the way he characterizes the curriculum. The findings in this study are separated into curriculum and instruction domains. First, the Chemistry 299 curriculum was designed to make the epistemological practices of scientists "accessible" to students by emphasizing epistemic development with respect to their ideas about scientific inquiry and science learning. Using student learning as a gauge for progress, I identify specific design elements that developed transferable inquiry skills as a means to support scientific literacy and pre-service teacher education. Second, the instruction-related findings built upon the insight I gained through

  6. Curriculum-Dependent and Curriculum-Independent Factors in Preservice Elementary Teachers' Adaptation of Science Curriculum Materials for Inquiry-Based Science

    Forbes, Cory T.

    2013-02-01

    In this nested mixed methods study I investigate factors influencing preservice elementary teachers' adaptation of science curriculum materials to better support students' engagement in science as inquiry. Analyses focus on two `reflective teaching assignments' completed by 46 preservice elementary teachers in an undergraduate elementary science methods course in which they were asked to adapt existing science curriculum materials to plan and enact inquiry-based science lessons in elementary classrooms. Data analysis involved regression modeling of artifacts associated with these lessons, as well as in-depth, semester-long case studies of six of these preservice teachers. Results suggest that features of the existing science curriculum materials, including measures of how inquiry-based they were, have a relatively small influence on the preservice teachers' curricular adaptations, while teacher-specific variables account for a much greater percentage of the variance. Evidence from the case studies illustrates the critical impact of the preservice teachers' field placement contexts as an explanatory, teacher-specific factor in their curricular adaptations. These findings have important implications for science teacher educators and science curriculum developers, in terms of not only better understanding how preservice teachers engage with curriculum materials, but also how programmatic features of teacher education programs influence their ability to do so.

    Pediatric asthma is a serious public health problem in Chicago and has been designated a high priority concern by residents of Chicago's Humboldt Park, a diverse community area with a large number of Puerto Rican, African American, and Mexican American families. In May 2009, following the principles of community-based participatory research, a cross-sectional asthma screening survey was administered to adult caregivers of children attending two Humboldt Park elementary schools. Data were analyzed to determine the prevalence of diagnosed and probable asthma as well as the degree of asthma control among affected children; associations between asthma outcomes and mutable triggers were evaluated. Surveys from 494 children were evaluated. Physician-diagnosed asthma was reported for 24.9% of children and probable asthma identified in an additional 16.2% of children. Asthma was poorly or moderately controlled in 60.0% of diagnosed children. Smoking occurred inside 25.0% of households and 75.0% of caregivers reported idling of vehicles in their community. Report of general stress among caregivers, stress due to community crime, and/or an inability to cope with everyday life were significantly and positively associated with poor asthma morbidity and control among affected children. Despite high prevalence rates and poor asthma morbidity and control in Humboldt Park, the association of these measures with mutable variables is promising. A community-based asthma intervention to address the issues identified in this study is needed to affect positive change.

    This study focuses on elementary teachers' comprehension of flooding before and after inquiry-based professional development (PD). There was an improvement in teachers' understanding toward a normative view from pre- to post-test (n = 17, mean gain = 4.3, SD = 3.27). Several misunderstandings and a general lack of knowledge about flooding emerged from the geoscience content two-tier pre-test, some of which persisted throughout the PD seminar while other responses provided evidence of teachers' improved understanding. The concepts that teachers struggled with were also apparent upon examining teachers' reflections upon their learning and teaching practices throughout the seminar. Teachers were challenged as they attempted to add new academic language, such as storm surge and discharge, to their prior understandings. Flooding concepts that teachers showed the least improvement on included analyzing a topographic region, reading a map image, and hydrograph interpretation. Teachers' greatest areas of improved understanding occurred in understanding the probability and role of ground conditions in flooding events. Teachers demonstrated considerable growth in their understanding of some flooding concepts through scaffolded inquiry lessons modeled throughout the PD. Those teachers who had greater prior knowledge and demonstrated more use of self-regulated learning showed the most change toward a normative view of flooding. The explicit modeling and participation in inquiry-based science activities and written responses to self-regulatory learning prompts throughout the seminar supported teachers' learning.

    2010-05-01

    The Trends in International Mathematics and Science Study (TIMSS) Video Study explored instructional practices in the United States (US) in comparison with other countries that ranked higher on the 1999 TIMSS assessment, and revealed that 8th grade science teachers in the US emphasize activities over content during lessons (Roth et al. 2006). This study applies the content framework from the TIMSS Video Study to a sample of 28 3rd grade teachers enacting an inquiry-based unit on floating and sinking, and seeks a deeper understanding of teachers’ practices through analysis of interviews with those teachers. Transcripts of observed lessons were coded according to the TIMSS framework for types of content, and transcripts of teacher interviews were coded to capture the ways in which teachers described their role in and purposes for teaching science, particularly with respect to the floating and sinking unit. Results indicate that teachers focused more on canonical, procedural and experimental knowledge during lessons than on real-world connections and the nature of science; however, none of the types of content received major emphasis in a majority of the classrooms in the sample. During interviews, teachers described their practice in ways that prioritized helping students to like science over specific content outcomes. The study suggests that elementary school teachers’ emphasis on doing and feeling during inquiry-based lessons may interfere with teaching of content.

    2017-06-01

    Given reform recommendations emphasizing scientific inquiry and empirical evidence pointing to the difficulties beginning teachers face in enacting inquiry-based science, this study explores a well-started beginning elementary teacher's (Sofia) beliefs about inquiry-based science and related instructional practices. In order to explore Sofia's beliefs and instructional practices, several kinds of data were collected in a period of 9 months: a self-portrait and an accompanying narrative, a personal philosophy assignment, three interviews, three journal entries, ten lesson plans, and ten videotaped classroom observations. The analysis of these data showed that Sofia's beliefs and instructional practices were reform-minded. She articulated contemporary beliefs about scientific inquiry and how children learn science and was able to translate these beliefs into practice. Central to Sofia's beliefs about science teaching were scientific inquiry and engaging students in investigations with authentic data, with a prevalent emphasis on the role of evidence in the construction of scientific claims. These findings are important to research aiming at supporting teachers, especially beginning ones, to embrace reform recommendations.

  16. Task-based Language Learning in Bilingual Montessori Elementary Schools: Customizing Foreign Language Learning and Promoting L2 Speaking Skills

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Foreign language learning has been a part of German elementary schools for several years now. Montessori schools focusing on individual learning, i.e. mostly independent from the teacher and based on auto-education, interest, and free choice, are also asked to teach an L2. The original lack of a concept of L2 learning for this environment has brought forth different approaches. Bilingual education seems to be feasible and applicable in Montessori education. The downside to this is that even in a bilingual classroom the Montessori way of learning may not allow for very much oral production of the foreign language. The role of L2 production (cf. Swain 1985, 1995, 2005 for language acquisition has been theoretically claimed and empirically investigated. Output can have a positive influence on L2 learning (cf. e.g. Izumi 2002, Keck et al. 2006. This also applies to interaction (cf. Long 1996, where negotiation of meaning and modified output are factors supporting L2 development (cf. e.g. de la Fuente 2002, McDonough 2005. Task-based Language Learning (TBLL presents itself as one way to promote oral language production and to provide opportunities for meaning-negotiation. Especially tasks with required information exchange and a closed outcome have been shown to be beneficial for the elicitation of negotiation of meaning and modified output. This paper argues that TBLL is a promising approach for the facilitation of L2 production and thus the development of speaking skills in a Montessori context. It also hypothesizes that TBLL can be implemented in a bilingual Montessori environment while still making the Montessori way of learning possible. Different tasks on various topics, examples of which are presented in this article, can lay the foundation for this. Offering such tasks in a bilingual Montessori elementary classroom promises to foster language production and the use of communication strategies like negotiation of meaning, both being

    Motivation: In the available databases, biological processes are described from molecular and cellular points of view, but these descriptions are represented with text annotations that make it difficult to handle them for computation. Consequently, there is an obvious need for formal descriptions of biological processes. Results: We present a formalism that uses the BioΨ concepts to model biological processes from molecular details to networks. This computational approach, based on elementary bricks of actions, allows us to calculate on biological functions (e.g. process comparison, mapping structure–function relationships, etc.). We illustrate its application with two examples: the functional comparison of proteases and the functional description of the glycolysis network. This computational approach is compatible with detailed biological knowledge and can be applied to different kinds of systems of simulation.

    This causal-comparative descriptive study investigated the achievement of pre-service elementary teachers taking an introductory physical science course that integrates inquiry-based instruction with computer simulations. The study was intended to explore if pre-service elementary teachers with different attitudes towards science as well as students with different learning styles would benefit differentially. Four research questions including four hypotheses were developed. The first major question consist of four specific hypothesis that addressed preservice elementary teachers' learning styles (Active/Reflective, Sensing/Intuitive, Visual/Verbal, and Sequential/Global) and their conceptual understanding of chemistry and the particulate nature of matter in a science class which use hands-on learning integrated with computer based simulated activities. The second major question pertained to the relationship between preservice teachers learning science and chemistry and their attitude towards science. The third major question related to preservice elementary teachers science and chemistry achievement gain scores and attitude average affected by their learning styles. Finally, the fourth question pertained to the dissipation or the minimization of preservice elementary teachers' science and chemistry misconceptions over the course of study. Three instruments were given to preservice elementary teachers in three different classes: pretest/posttest for the science conceptual understanding examination, and pretest-only for the science attitude and learning styles instruments. Total usable science attitude surveys returned was 67 out of 70. The overall average mean was 3.13 (SD = .51) on a five point scale. Total return of science achievement instrument was 65, with a total mean test score (quantitative and qualitative together) of 6.38 (SD = 3.05) on the pretest, with a post test mean of 9.06 (SD = 4.19). Results revealed no statistically significant achievement gain

    Schools are considered an attractive setting to promote healthy living behaviors in children, but previous school-based interventions aimed at preventing weight gain in children have yielded mixed results. Novel school-based approaches are needed to modify healthy living behaviors and attenuate weight gain in children. To assess the effectiveness of a peer-led healthy living program called Healthy Buddies on weight gain and its determinants when disseminated at the provincial level to elementary school students. Cluster-randomized effectiveness trial performed during the 2009-2010 school year. Baseline and follow-up measurements were made in October 2009 and May 2010, respectively. The study was performed in 19 elementary schools in Manitoba, Canada, and included 647 elementary school students aged 6 to 12 years (48% girls). Schools were randomized to receive regular curriculum or Healthy Buddies lesson plans. Lesson plans were delivered by older (9- to 12-year-old) elementary school students to the younger (6- to 8-year-old) peers and targeted 3 components of health: physical activity, healthy eating, and self-esteem and body image. The primary outcome measures were the change in waist circumference and body mass index z score. Secondary outcomes included physical activity (steps per day), cardiorespiratory fitness, self-efficacy, healthy living knowledge, and self-reported dietary intake. At baseline, 36% of children were overweight or obese and 11% achieved the recommended 13,500 steps per day. Intention-to-treat analyses showed that waist circumference declined significantly in the intervention group relative to controls: -1.42 cm (-2.68 to -0.17; P = .03). Reductions in waist circumference were particularly significant for children who were younger, overweight or obese, or attending First Nations schools. No difference in body mass index z score was observed between groups. Self-efficacy, healthy living knowledge, and dietary intake significantly improved

    Substantial research illuminates many factors effecting the implementation of evidence-based mental health promotion programs in schools; however, research on how schools plan for sustaining their investments in these programs is limited. In this qualitative study, we elicited descriptions of opportunities and challenges for sustainability. We interviewed 24 individuals from schools involved in a longitudinal, qualitative research project that followed uptake and implementation of the evidence-based WITS Programs across 2 years (Leadbeater et al. 2012). WITS stands for Walk away, Ignore, Talk it out and Seek help and the online WITS Programs focus on preventing peer victimization ( www.witsprograms.ca ). Our findings suggest that sustainability planning in schools is not merely a next step following high quality implementation, but rather involves multiple ongoing processes that need to be anticipated and supported by school leadership and program champions and developers in order to realize investments in evidence-based programs.

    To measure academic achievement of the multiple intelligence-based learning medium via a tablet device. This is a quasi-experimental research study (non-randomized control group pretest-posttest design) in 62 grade 1 elementary students (33 males and 29 females). Thirty-one students were included in an experimental group using purposive sampling by choosing a student who had highest multiple intelligence test scores in logical-mathematic. Then, this group learned by the new learning medium via a tablet which the application matched to logical-mathematic multiple intelligence. Another 31 students were included in a control group using simple random sampling and then learning by recitation. Both groups did pre-test and post-test vocabulary. Thirty students in the experimental group and 24 students in the control group increased post-test scores (odds ratio = 8.75). Both groups made significant increasing in post-test scores. The experimental group increased 9.07 marks (95% CI 8.20-9.93) significantly higher than the control group which increased 4.39 marks (95% CI 3.06-5.72) (t = -6.032, df = 51.481, p learning from either multiple intelligence-based learning medium via a tablet or recitation can contribute academic achievement, learningfrom the new medium contributed more achievement than recitation. The new learning medium group had higher post-test scores 8.75 times than the recitation group. Therefore, the new learning medium is more effective than the traditional recitation in terms of academic achievement. This study has limitations because samples came from the same school. However, the previous study in Thailand did notfind a logical-mathematical multiple intelligence difference among schools. In the future, long-term research to find how the new learning medium affects knowledge retention will support the advantage for life-long learning.

    Victims of bullying are at risk for psychotic experiences in early adolescence. It is unclear if this elevated risk extends into late adolescence. The aim of this study was to test whether bullying perpetration and victimization in elementary school predict psychotic experiences in late adolescence. The current study is based on the Avon Longitudinal Study of Parents and Children (ALSPAC), a prospective community-based study. A total of 4720 subjects with bullying perpetration and victimization were repeatedly assessed between the ages of 8 and 11 years by child and mother reports. Suspected or definite psychotic experiences were assessed with the Psychosis-Like Symptoms semi-structured interview at age 18 years. Controlling for child's gender, intelligence quotient at age 8 years, childhood behavioural and emotional problems, and also depression symptoms and psychotic experiences in early adolescence, victims [child report at 10 years: odds ratio (OR) 2.4, 95% confidence interval (CI) 1.6-3.4; mother report: OR 1.6, 95% CI 1.1-2.3], bully/victims (child report at 10 years: OR 3.1, 95% CI 1.7-5.8; mother: OR 2.9, 95% CI 1.7-5.0) and bullies (child report at 10 years: OR 4.9, 95% CI 1.3-17.7; mother: OR 1.2, 95% CI 0.46-3.1, n.s.) had a higher prevalence of psychotic experiences at age 18 years. Path analysis revealed that the association between peer victimization in childhood and psychotic experiences at age 18 years was only partially mediated by psychotic or depression symptoms in early adolescence. Involvement in bullying, whether as victim, bully/victim or bully, may increase the risk of developing psychotic experiences in adolescence. Health professionals should ask routinely during consultations with children about their bullying of and by peers.

    Children evacuation is a critical but challenging issue. Unfortunately, existing researches fail to effectively describe children evacuation, which is likely due to the lack of experimental and empirical data. In this paper, a questionnaire-based experiment was conducted with children aged 8-12 years to study children route choice behavior during evacuation from in a classroom with two exits. 173 effective questionnaires were collected and the corresponding data were analyzed. From the statistical results, we obtained the following findings: (1) position, congestion, group behavior, and backtracking behavior have significant effects on children route choice during evacuation; (2) age only affects children backtracking behavior, and (3) no prominent effects based on gender and guidance were observed. The above findings may help engineers design some effective evacuation strategies for children.

    The intent of national efforts to frame science education standards is to promote students' development of scientific practices and conceptual understanding for their future role as scientifically literate citizens (NRC 2012). A guiding principle of science education reform is that all students receive equitable opportunities to engage in rigorous science learning. Yet, implementation of science education reform depends on teachers' instructional decisions. In urban schools serving students primarily from poor, diverse communities, teachers typically face obstacles in providing reform-based science due to limited resources and accountability pressures, as well as a culture of teacher-directed pedagogy, and deficit views of students. The purpose of this qualitative research was to study two white, fourth grade teachers from high-poverty urban schools, who were identified as transforming their science teaching and to investigate how their beliefs, knowledge bases, and resources shaped their planning for reform-based science. Using the Shavelson and Stern's decision model for teacher planning to analyze evidence gathered from interviews, documents, planning meetings, and lesson observations, the findings indicated their planning for scientific practices was influenced by the type and extent of professional development each received, each teacher's beliefs about their students and their background, and the mission and learning environment each teacher envisioned for the reform to serve their students. The results provided specific insights into factors that impacted their planning in high-poverty urban schools and indicated considerations for those in similar contexts to promote teachers' planning for equitable science learning opportunities by all students.

    Schools are a source of epidemic seasonal dissemination-in particular gastroenteritis among children and the general population. We assessed the impact of an alcohol-based sanitizer on gastroenteritis and its subsequent consequences. A study was conducted in 2 primary schools over a 17-week period, before and throughout the seasonal gastroenteritis period. The intervention, under strict teacher supervision and in a realistic and long lasting manner, consisted of 1 school rubbing an alcohol-based sanitizer into the hands of the school children. The primary outcome was the proportion of children without any occurrence of gastroenteritis during the study period both in the treated group and the control group, which were 2 separate schools. A Cox proportional hazards model was used to assess the hazard ratio. Secondary outcomes were the number of gastroenteritis episodes, doctor appointments, absenteeism, and working days lost by a parent. Four thousand six hundred fifty-four weekly questionnaires were collected. One hundred fifty-five children presented with at least 1 occurrence of gastroenteritis during the study period: 64 of 259 in the treatment group and 91 of 217 in the control group (χ2 = 16.4, P < 0.0001). The instantaneous risk of primary infection, at any time of the study, for children receiving the treatment was multiplied by 0.52 (95% CI: [0.37,0.71]) compared with children not receiving the treatment. The average number of gastroenteritis episodes was 0.31 in the treatment group and 0.53 in the control group (P < 0.001). Systematic and controlled use of alcohol-based sanitizers during the epidemic season could significantly reduce the incidence of gastroenteritis in primary school children.

  17. Proposed guidance for carryover studies, based on elementary equivalence testing techniques.

    2014-01-01

    Carryover experiments are widely used for clinical chemistry and immunochemistry analysers to evaluate and validate carryover effects. The experimental design is well described. However, there is no guideline on the statistical approach on data analysis, especially if absence of carryover has to be shown. The only reporting of carryover in ppm is not helpful because its uncertainty is not taken into account. Furthermore, the most commonly used method fails to demonstrate the absence of carryover. We propose a step-by-step guidance applying a new statistical design for analysis of carryover studies based on equivalence testing, and provide a sample based tutorial. For statistical analysis of carryover effects an one-sided version of equivalence testing by comparing the difference with a predefined limit (i.e., a test of non-superiority) is used. The methodology is demonstrated by measuring total betahCG in human serum samples with a UniCel DxI 880 analyser. A new statistical approach based on equivalence testing has been developed for analysis of data resulting from a typical experimental protocol for carryover studies. Experiments using 8 (11) cycles of high and low concentration samples are appropriate to validate the absence of carryover with 80% (90%) power and an alpha-level of 0,05 if no carryover is expected. We propose to predefine an acceptance criterion based on the imprecision (here: expressed as one standard deviation) observed for those replicates of the low concentration samples expected to be unaffected by carryover. In the demonstration, the absence of carry-over was concluded with a significance of p < 0.05. Appropriate statistical methods should be applied when the target of a method-validation experiment is (i) absence of any effect, (ii) non-inferiority/non-superiority or (iii) equivalence. Using the example of carryover studies, we show that one-sided equivalence testing is the proper model, and propose a guidance for analysis of these

    2016-01-01

    Child trauma is a mental health concern and more information is needed about treatment in community mental health settings. This article presents results of a focus group and member checking sessions held with counselors who provided therapy for children experiencing posttraumatic stress disorder in a community-based setting. Results indicated that play and art techniques were commonly used during individual child therapy sessions. Sessions were child-directed and allowed children to review trauma experiences in a "safe" setting with an "expert" guide. Several themes were commonly addressed in sessions including opportunities to re-experience, release, and reorganize the trauma, building resilience or self-esteem for the child, promoting safety, and helping the child to regulate emotional reactions and behavior problems. Counselors focused on discussing ways to interact with the child to promote healing and there was a belief that children would return to a positive developmental trajectory after coping with traumatic experiences. Future research needs to address what works for whom, in terms of what interventions are useful in child-directed counseling sessions for children who have experienced specific types of trauma, such as sexual and physical abuse or witnessing domestic violence. Integration of knowledge from evidence-based treatments will also further inform clinical practice with children who have experienced traumatic events.

    Full Text Available After 40 years of ethnomathematics research in Papua New Guinea and policies encouraging ethnomathematics in schools, it was time to look at professional learning for teachers so they could effectively implement the policies. Within a design-based research methodology, we designed a set of interlinked principles, tried them in several workshops for teachers, and revised the principles to take account of needs based on reflexivity and evaluations. We developed a manual to use in the workshops. We are continuing this research through several different phases, moving from direct delivery of the professional learning to teachers in various provinces and ecologies to delivery to trainers who then teach the teachers in three provinces, and finally by technology delivery. Early evaluation data suggest that the key principles showing the importance of culture, language and mathematical thinking in the teaching of early mathematics are sound. Workshops have been well received as teachers inquire into the mathematics of their own cultures. The need for a stronger understanding of early mathematics learning in general has been identified. The use of video of cultural practice and of young children learning to count and investigate has had a significant impact.

    Educational interventions to reduce Lyme disease (LD) among at-risk school children have had little study. The purpose of this study was to evaluate whether a short in-class LD education program based on social learning theory and the Health Belief Model (HBM) impacted a child's knowledge, attitude, and preventive behavior. Students in grades 2-5 in 19 elementary schools were selected in an area that was highly endemic for LD. The children received an educational intervention or were on a wait list as controls. Their knowledge, attitudes, and self-reported preventive behaviors were surveyed before implementing the program and 1 year later. General linear regression analyses adjusting for age, gender, and baseline variables were used to measure the impact of the intervention. There were 3570 participants in the study: 1562 received the intervention, and 2008 were controls. The mean age for both groups was 9.1 years, with 53% women in the intervention group and 50% women in the control group. The children in the intervention group increased their overall knowledge of LD more than the children in the control group (overall knowledge score improvement, mean difference (SD) 1.38 (1.3) vs. 0.36 (1.3) p children in classes receiving the intervention reported an increase in precautionary behavior, positive attitude toward taking precautions, and self-efficacy compared with the wait list controls. Two LD cases were confirmed during the follow-up period, one in the intervention group and one in the controls. These findings demonstrate that a short in-class educational program that includes elements of the HBM, including: (1) awareness and knowledge about the disease, (2) benefits of preventive behavior, and (3) confidence in ability to perform preventive behaviors can improve knowledge, attitude, and self-reported precautionary behavior among at-risk children. www.clinicaltrials.gov : NCT00594997.

    School recess before lunch (e.g., reverse recess) has been suggested as a means to improve dietary intake and classroom behavior but limited research explores this school-based policy. This pilot study tests the impact of recess scheduling on dietary intake at school lunch. A mixed methods approach included assessment of dietary intake assessed by measured plate waste on five non-consecutive days at Madras Elementary School, Madras, Oregon, United States (n = 104 intervention; 157 controls). Subjects included primary school children in grades kindergarten, first and second. Logistic regression was used to test associations between recess timing and dietary intake. Four focus groups involving teachers and staff explored reactions to the intervention. Qualitative data was transcribed verbatim and assessed for key themes. Milk consumption was 1.3 oz greater in the intervention group (5.7 oz vs. 4.4 oz); and 20% more of the intervention participants drank the entire carton of milk (42% vs. 25%, p < 0.0001). Intervention participants were 1.5 times more likely to meet the nutritional guidelines for calcium (≥267 mg, p = 0.01) and fat (≤30% of total energy, p = 0.02). Consumption of entrees, vegetables, and fruits did not differ between groups. Teachers perceived recess before lunch beneficial to classroom behavior and readiness to concentrate following lunch. The recess before lunch intervention yielded increased milk consumption; the nutritional and social benefits observed warrant policy change consideration. Future research should assess the impact of recess before lunch in larger districts.

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

    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.

    Childhood obesity is a significant but largely modifiable health risk, disproportionately affecting socioeconomically disadvantaged, racial/ethnic minority, and rural children. Elementary school-aged children typically experience the greatest increases in excess weight gain and therefore are important targets for reducing adolescent and adult obesity while improving children's health. Our study evaluated outcomes of a 3-year elementary school-based program for reducing obesity in American Indian and White students attending eight rural schools in the U.S. upper Midwest. Researchers measured body mass indexes (BMI) and other health indicators and behaviors of 308 beginning third-grade students and then again at the end of students' third, fourth, and fifth grades. The primary focus of this study is a mixed multilevel longitudinal model testing changes in age- and gender-adjusted BMI z scores ( zBMI). There was a significant decrease in zBMI across the 3-year study period. Ethnicity analyses showed that White students had overall decreases in zBMI whereas American Indian students' zBMIs remained stable across the program. Comparisons with children from an age- and cohort-matched national sample provided support for the effectiveness of the school program in reducing BMI and obesity during the study period. An elementary school-based health program that addresses a range of students' obesity-related health behaviors, the school health environment, and that involves educators and parents is an effective intervention for reducing or stabilizing BMI in rural White and American Indian students. School health programs for students living in rural communities may be especially effective due to greater school and community cohesiveness, and valuing of the school's primary role in improving community health.

    Highlights: > Five new elementary chaotic snap flows and a generalization of an existing chaotic snap flow have been presented. > Three of all are conservative systems whilst three others are dissipative systems. > Four cases need only a single control parameter and a single nonlinearity. > A cubic case in a jerk representation requires only two terms and a single nonlinearity. - Abstract: Hyperjerk systems with 4th-order derivative of the form x{sup ....}=f(x{sup ...},x{sup ..},x{sup .},x) have been referred to as snap systems. Five new elementary chaotic snap flows and a generalization of an existing flow are presented through an extensive numerical search. Four of these flows demonstrate elegant simplicity of a single control parameter based on a single nonlinearity of a quadratic, a piecewise-linear or an exponential type. Two others demonstrate elegant simplicity of all unity-in-magnitude parameters based on either a single cubic nonlinearity or three cubic nonlinearities. The chaotic snap flow with a single cubic nonlinearity requires only two terms and can be transformed to its equivalent dynamical form of only five terms which have a single nonlinearity. An advantage is that such a chaotic flow offers only five terms even though the (four) dimension is high. Three of the chaotic snap flows are characterized as conservative systems whilst three others are dissipative systems. Basic dynamical properties are described.

    Full Text Available Sedentary lifestyle and great advertising of high calorie junk foodstuffs cause the change of the nutritional pattern of children and adolescents. This study has been carried out with this objective: determining the effect of educational intervention based on the theory of planned behavior on reducing consumption of unhealthy snacks in the elementary students in Kermanshah City in 2015-2016. This research is a quasi-experimental study. Research setting was the primary schools in Kermanshah city. Sampling was conducted in multi-stage random method. Three hundred and fourteen female and male students were selected randomly. They were divided into two groups of Case and Control. The data collection tool in this study was a questionnaire. Status of snacks consumption among students in both study groups was examined after four weeks. Descriptive statistics and inferential statistics were used in order to analyze data. Before intervention, there were no significant differences between two groups of case and control. The average grades of the theory of planned behavior structures have increased in case group after intervention and it shows a significant difference (P < 0.05. No significant differences were observed in each structure in control group after intervention. The results indicate the positive effect of educational intervention based on the theory of planned behavior on reducing consumption of unhealthy snacks in elementary students. Theory-based educational intervention has also increased students’ willingness to consume healthy snacks.

    Full Text Available Abstract Background Studies about the relationship between high-molecular-weight adiponectin (HMW-adn and anthropometric variables among population-based elementary schoolchildren have been too limited, especially in Japan, where blood collection is not usually performed in the annual health examination at elementary schools. The objective of the present study was to investigate the relationship between HMW-adn and anthropometric variables (body mass index [BMI], percent body fat [%BF], waist circumference [WC], and waist-to-height ratio [WHtR] among population-based elementary schoolchildren in Japan. Methods Subjects comprised all fourth-grade schoolchildren (9 or 10 years of age in the town of Ina, Saitama Prefecture, Japan during 2005–2008 (N = 1675. After excluding 21 subjects because of refusal to participate or incomplete data, data from a total of 1654 subjects (846 boys and 808 girls were analyzed. The height, weight, %BF, and WC of each subject were measured, while blood samples were drawn from the subjects to measure adiponectin levels (HMW-adn and total adiponectin. Childhood obesity was determined according to the age- and sex-specific cut-off points proposed by the International Obesity Task Force. Spearman’s correlation coefficients between adiponectin levels and anthropometric variables were calculated for each sex. Results The anthropometric variables were negatively correlated with HMW-adn in both boys and girls. Correlation coefficients of HMW-adn with anthropometric variables in the obesity group were consistently higher than those in the non-obesity group among both boys and girls. In addition, only WHtR was significantly correlated with HMW-adn regardless of sex and physique (obesity or non-obesity; the correlation coefficient was -0.386 among boys and -0.543 among girls in the obesity group, while it was -0.124 among boys and -0.081 among girls in the non-obesity group. Conclusions HMW-adn was negatively correlated

    The aim was to comprehensively examine school-based tobacco policy status, implementation and students' perceived smoking at school in regard to gender-specific differences in smoking behavior. We conducted a multilevel-based study to assess two-level effects for smoking among 2350 grades three to six students in 26 randomly selected elementary schools in southern Taiwan. A series of multilevel models were analyzed separately for male and female students. The school-level variables appear to be related to smoking behavior in male students. Among males, the risk of ever-smoking was significantly associated with those schools without antitobacco health education activities or curricula [adjusted odds ratio (aOR) = 6.23, 95% confidence interval (CI): 2.55-15.24], with a high perceived smoking rate (aOR = 3.08, 95% CI: 1.41-6.72) and located in a mountainous region (aOR = 2.53, 95% CI: 1.15-5.58). The risk of ever-smoking among females was significantly associated with those schools without antitobacco activities or curricula (aOR = 3.10, 95% CI: 1.27-7.55). As compared with female counterparts, the specific school that the male students attended had a positive significant effect on the risk of being ever-smokers. The findings suggest that effective tobacco policy implementation should be considered in elementary schools that are currently putting children at the greatest risk for cigarette smoking, especially in regard to male students.

  1. Increasing Bellevue School District's elementary teachers' capacity for teaching inquiry-based science: Using ideas from contemporary learning theory to inform professional development

    Science.gov (United States)

    Maury, Tracy Anne

    This Capstone project examined how leaders in the Bellevue School District can increase elementary teachers' capacity for teaching inquiry-based science through the use of professional learning activities that are grounded in ideas from human learning theory. A framework for professional development was constructed and from that framework, a set of professional learning activities were developed as a means to support teacher learning while project participants piloted new curriculum called the Isopod Habitat Challenge. Teachers in the project increased their understanding of the learning theory principles of preconceptions and metacognition. Teachers did not increase their understanding of the principle of learning with understanding, although they did articulate the significance of engaging children in student-led inquiry cycles. Data from the curriculum revision and professional development project coupled with ideas from learning theory, cognition and policy implementation, and learning community literatures suggest Bellevue's leaders can encourage peer-to-peer interaction, link professional development to teachers' daily practice, and capitalize on technology as ways to increase elementary teachers' capacity for teaching inquiry-based science. These lessons also have significance for supporting teacher learning and efficacy in other subject areas and at other levels in the system.

    Full Text Available Children need adequate and healthy nutrition for sufficient mental development and physical growth. Children also need nutrition education to gain the required skills for correct food selection. This study aimed to evaluate the effect of the child-to-child approach based on the Theory of Planned Behavior (TPB on the eating behaviors of elementary school students in Iran. In this quasi-experimental, interventional study with pretest/posttest design and a control group, 173 fourth grade female students of public elementary schools were selected using multistage random cluster sampling. Educational intervention was performed for the intervention group through the child-tochild approach. The research data were collected in the two groups using a 5-scale researcher-made questionnaire based on the constructs of TPB with a Cronbach's alpha of 0.86 before and one and six weeks after the intervention. Then, the data were analyzed using chi-square test, repeated measures ANOVA, and independent t-test. The results showed a significant difference between the two groups regarding the mean scores of attitude, perceived behavioral control, and behavioral intention before and one and six weeks after the intervention. However, no significant difference was found between the two groups concerning the mean score of subjective norms. Moreover, the educational intervention resulted in improvement of the intervention group’s eating behaviors. The findings of this research suggested the child-to-child approach and the TPB as effective methods in improvement of correct eating behaviors in children.

  3. Using authentic intellectual assessment to determine level of instructional quality of teacher practice of new elementary school teachers based on teacher preparation route

    Cassidy, Kimberly E.

    This study was designed to determine whether or not differences existed in the effectiveness between teachers from traditional and alternative teacher preparation routes. The NCLB requirement of having a highly qualified teacher in every classroom has brought close attention to the assessment of teacher effectiveness and the preparation of teacher candidates. The study population included elementary school teachers, within their first three years of teaching who taught science, from five southeastern Virginia schools. For this study, an authentic intellectual assessment rubric created by Newmann, Bryk, and Nagaoka (1997) was utilized to measure teacher effectiveness in terms of the level of instructional quality of new teachers. Chi-square and t test analyses were conducted to investigate the difference between scores of science lesson assignments of new elementary teachers based on type of teacher preparation route the teachers completed. The critical finding of the study was that whereas there were no statistically significant differences in the science assignment scores between traditionally and alternatively prepared teachers, there were significant weaknesses in all teacher participants in the areas of construction of knowledge and connection to students' lives. The results of this study have implications for teachers, teacher preparation routes, teacher development coordinators of school divisions, and those in charge of instructional policies.

    Full Text Available Abstract Background Children who participate in regular physical activity obtain health benefits. Preliminary pedometer-based cut-points representing sufficient levels of physical activity among youth have been established; however limited evidence regarding correlates of achieving these cut-points exists. The purpose of this study was to identify correlates of pedometer-based cut-points among elementary school-aged children. Method A cross-section of children in grades 5-7 (10-12 years of age were randomly selected from the most (n = 13 and least (n = 12 'walkable' public elementary schools (Perth, Western Australia, stratified by socioeconomic status. Children (n = 1480; response rate = 56.6% and parents (n = 1332; response rate = 88.8% completed a survey, and steps were collected from children using pedometers. Pedometer data were categorized to reflect the sex-specific pedometer-based cut-points of ≥15000 steps/day for boys and ≥12000 steps/day for girls. Associations between socio-demographic characteristics, sedentary and active leisure-time behavior, independent mobility, active transportation and built environmental variables - collected from the child and parent surveys - and meeting pedometer-based cut-points were estimated (odds ratios: OR using generalized estimating equations. Results Overall 927 children participated in all components of the study and provided complete data. On average, children took 11407 ± 3136 steps/day (boys: 12270 ± 3350 vs. girls: 10681 ± 2745 steps/day; p After adjusting for all other variables and school clustering, meeting the pedometer-based cut-points was negatively associated (p Conclusions Comprehensive multi-level interventions that reduce screen-time, encourage active travel to/from school and foster a physically active classroom culture might encourage more physical activity among children.

    The study explored the effects of a phonics-based early intervention package on the early reading skills of three preschool students who were d/Deaf or hard of hearing who differed in regard to degree of hearing loss, use of amplification, and communication mode. The 40-week intervention (50-week in one case) was delivered through individual and group phonics-based instruction supplemented by Visual Phonics in a language-enriched preschool classroom. Standardized assessments were conducted before, during, and after the intervention. Along with some additional assessments, the same assessments were conducted in early elementary school. The results showed that all participants demonstrated at least some use of phonemic awareness and phonics skills when they were explicitly trained, and that these skills were sustained in early elementary school. Furthermore, all participants exhibited overall reading levels at or above age level when measured in early elementary school.

    2013-12-01

    Elementary modes (EMs) are steady-state metabolic flux vectors with minimal set of active reactions. Each EM corresponds to a metabolic pathway. Therefore, studying EMs is helpful for analyzing the production of biotechnologically important metabolites. However, memory requirements for computing EMs may hamper their applicability as, in most genome-scale metabolic models, no EM can be computed due to running out of memory. In this study, we present a method for computing randomly sampled EMs. In this approach, a network reduction algorithm is used for EM computation, which is based on flux balance-based methods. We show that this approach can be used to recover the EMs in the medium- and genome-scale metabolic network models, while the EMs are sampled in an unbiased way. The applicability of such results is shown by computing “estimated” control-effective flux values in Escherichia coli metabolic network.

    2017-04-01

    Culturally-based risk behavior prevention programs for American Indian elementary school children are sparse. Thus a group of American Indian educators collaborated in the creation of a program that helps children make healthy decisions based on their cultural and traditional value system. In this paper the effectiveness of Lakota Circles of Hope (LCH), an elementary school culturally-based prevention program was studied and evaluated. Three cohorts of fourth and fifth graders participated in a mixed methods quasi-experimental evaluative research design that included focus groups and surveys prior to and following the intervention. Five research questions regarding the program's impact on students' self-esteem and self-efficacy, Lakota identity, communication, conflict resolution and risk behaviors were addressed in this study. Participants were compared to non-participants in three American Indian reservation school sites. Educators completed a survey to record their observations and feedback regarding the implementation of the program within their respective school sites. The study provides preliminary evidence that, when delivered with fidelity, LCH contributes to statistically significant changes in risk behaviors, Lakota identity, respect for others, and adult and parent communication. A two-way multivariate analysis of variance with post hoc analysis of data collected from the LCH participants (N = 1392) were used to substantiate a significant increase in respect for others and a decrease in risk behaviors which included alcohol, tobacco, and substance use at the 0.10 alpha level. Significant positive improvements in parent and adult communication and an increased Lakota identity at the 0.01 alpha level were obtained. There were no significant differences in self-esteem and conflict resolution from pre to post intervention and in comparison with non LCH participating students.

    Full Text Available Abstract Background The number of obese children in the US remains high, which is problematic due to the mental, physical, and academic effects of obesity on child health. Data indicate that school-age children, particularly underserved children, experience unhealthy gains in BMI at a rate nearly twice as fast during the summer months. Few efforts have been directed at implementing evidence-based programming to prevent excess weight gain during the summer recess. Methods Camp NERF is an 8-week, multi-component (nutrition, physical activity, and mental health, theory-based program for underserved school-age children in grades Kindergarten - 5th coupled with the USDA Summer Food Service Program. Twelve eligible elementary school sites will be randomized to one of the three programming groups: 1 Active Control (non-nutrition, physical activity, or mental health; 2 Standard Care (nutrition and physical activity; or 3 Enhanced Care (nutrition, physical activity, and mental health programming.

    The promotion of socio-emotional skills in educational contexts is highly beneficial to individuals' global adjustment and development. Evaluation research suggests that interventions for the promotion of socio-emotional skills are effective. However, most of this work has been carried out in the USA and there is now a pressing need to evaluate interventions at the cross-cultural level. This 4-year study evaluated the effectiveness of a teacher manual-based intervention for the promotion of social and emotional skills in Portuguese elementary school children. Using a quasi-experimental design, teachers taught manual-based strategies to children in the experimental group, focusing on specific social and emotional skills. These strategies were integrated as part of the curricular activities. Results showed statistically significant differences between the experimental group and the control group on the evaluated outcomes (self-control, emotional differentiation, emotional regulation, social skills, and self-esteem). For each of the dimensions studied, effect sizes were large (above 0.80). Findings are similar to those reported by international research evaluating the effectiveness of programmes for the promotion of social and emotional skills in school-age children. This study is an important contribution in the establishment of evidence-based socio-emotional skills programmes at the cross-cultural level.

    The recent NASA Mars Rover missions capture the imagination of children, as NASA missions have done for decades. The University of Houston is in the process of developing a prototype of a flexible program that offers children an in-depth educational experience culminating in the design and construction of their own model rover. The existing prototype program is called the Mars Rover Model Celebration. It focuses on students, teachers and parents in grades 3-8. Students will design and build a model of a Mars rover to carry out a student selected science mission on the surface of Mars. The model will be a mock-up, constructed at a minimal cost from art supplies. The students will build the models as part of a project on Mars. The students will be given design criteria for a rover and will do basic research on Mars that will determine the objectives and features of their rover. This project may be used either informally as an after school club or youth group activity or formally 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. The project's unique strength lies in engaging students in the process of spacecraft design and interesting them in aerospace engineering careers. The project is aimed at elementary and secondary education. Not only will these students learn about scientific fields relevant to the mission (space science, physics, geology, robotics, and more), they will gain an appreciation for how this knowledge is used to tackle complex problems. The low cost of the event makes it an ideal enrichment vehicle for low income schools. It provides activities that provide professional development to educators, curricular support resources using NASA Science Mission Directorate (SMD) content, and provides family opportunities for involvement in K-12 student learning. This paper will describe the development of a detailed set of new 5E lesson plans to

    This study aimed to determine the effect of a stroke education programme on elementary school students and their parental guardians in a rural area in Japan that has high stroke mortality. School class based intervention study. Eleven public elementary schools in Tochigi Prefecture, Japan. 268 students aged 11-12 years and 267 parental guardians. Students received lessons about stroke featuring animated cartoons and were instructed to communicate their knowledge about stroke to their parental guardians using material (comic books) distributed in the lessons. Stroke knowledge (symptoms, risk factors and attitude towards stroke) and behavioural change for risk factors were assessed at baseline, immediately after the programme and at 3 months. We also evaluated behavioural change for risk factors among parental guardians. The percentage of students with all correct answers for stroke symptoms, risk factors and the recommended response to stroke was significantly increased at 3 months P<0.001). We observed a significant increase in the percentage of guardians who chose all correct symptoms (P<0.001: 61.0% vs 85.4%) and risk factors (P<0.001: 41.2% vs 59.9%) at 3 months compared with baseline. The percentage of parental guardians with a high behavioural response to improving risk factors was significantly increased at 3 months compared with baseline (P<0.001). In a rural population with high stroke mortality, stroke education can improve knowledge about stroke in elementary school students and their parental guardians. We conducted the intervention as a part of compulsory education; this study was not a clinical trial.

    Stucke, Ann Hancock

    The problem. Recent reform efforts in science education have culminated in National Science Education Standards (NSES), which include the theme of inquiry across all grade levels. Consideration must be given to teachers' conceptions of inquiry, and their perceived roles, as they implement the processes of inquiry in the science classroom. Because of the change in pedagogy required by the standards, research efforts must address these areas. Research questions. The following research questions guided this study. (1) What are teachers' conceptions of inquiry? (2) What do the teachers consider important aspects of their roles when providing inquiry experiences for their students? (3) What do the teachers consider important aspects of the students' roles as inquirers? Research paradigm and methodology. The research paradigm that grounded this investigation is the constructivist paradigm proposed by Guba and Lincoln (1989). Participants were three elementary school teachers participating in the Elementary School Education Partners project. Qualitative methodology techniques used in the study included focus group discussion, semi-structured interviews, classroom observation with videotaping, teacher reflections, and fieldnotes. Data were analyzed using the constant comparative method as provided by Glaser and Strauss (1967). A case study format was used to discuss the results of themes that emerged. Results. Themes that emerged from the data were (a) inquiry is viewed as a teaching strategy; (b) the teachers' perceptions of the nature of inquiry are different from one another's; (c) there are differences in the degree of fit with the NSES description of inquiry; (d) the manner in which they see themselves as facilitators originates in their own educational experiences and varies from that of a guide, to a monitor, to one who models; and (e) teachers see the role of students as active participants in their learning but the teachers' perceptions of students' roles, as

    Current physics education research is faced with the important question of how best to introduce elementary particle physics in the classroom early on. Therefore, a learning unit on the subatomic structure of matter was developed, which aims to introduce 12-year-olds to elementary particles and fundamental interactions. This unit was iteratively evaluated and developed by means of a design-based research project with grade-6 students. In addition, dedicated professional development programmes were set up to instruct high school teachers about the learning unit and enable them to investigate its didactical feasibility. Overall, the doctoral research project led to successful results and showed the topic of elementary particle physics to be a viable candidate for introducing modern physics in the classroom. Furthermore, thanks to the design-based research methodology, the respective findings have implications for both physics education and physics education research, which will be presented during the PhD defen...

    Easy access to intervention and support for certain behaviors is important for obesity prevention and management. The available technology such as smartphone applications can be used for intervention regarding healthy food choices for obesity prevention and management in elementary-school students. The transtheoretical model (TTM) is comprised of stages and processes of change and can be adopted to tailored education for behavioral change. This study aims to develop TTM-based nutrition contents for mobile applications intended to change eating behaviors related to weight gain in young children. A synthesized algorithm for tailored nutrition messages was developed according to the intake status of six food groups (vegetables, fruits, sugar-sweetened beverages, fast food and instant food, snacks, and late-night snacks), decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. The messages in this study were developed from December 2014 to April 2015. After the validity evaluation of the contents through expert consultation, tailored nutrition information messages and educational contents were developed based on the TTM. Based on the TTM, stages of subjects are determined by their current intake status, decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. Three versions of tailored nutrition messages at each TTM stage were developed so as to not send the same messages for three weeks at most, and visual materials such as figures and tables were developed to provide additional nutritional information. Finally, 3,276 tailored nutrition messages and 60 nutrition contents for applications were developed. Smartphone applications may be an innovative medium to deliver interventions for eating behavior changes directly to individuals with favorable cost-effectiveness. In addition, using the TTM for tailored nutrition education for healthy eating is an effective approach.

    Full Text Available Elementary particles, i.e. the basic constituents of nature, are characterized by quantum recurrences in time. The flow of time of every physical system can be therefore decomposed in elementary cycles of time. This allows us to enforce the local nature of relativistic time, yielding interesting unified descriptions of fundamental aspects of modern physics, as shown in recent publications. Every particle can be regarded as a reference clock with time resolution of the order of the Compton time particle, many orders of magnitude more accurate than the atomic clocks. Here we report basic implications about the resulting notion of time.

  20. Complexities of learning with computer-based tools: A case of inquiry about sound and music in elementary school

    Science.gov (United States)

    Magnusson, Shirley J.

    1996-12-01

    Computer-based technology is increasingly becoming available for students at all grade levels in schools, and its promise and power as a learning tool is being extolled by many. From a constructive perspective, if individuals actively construct meaning from their experiences, then simply having particular tools to work with via a computer doesn't ensure that desired learning will result. Thus, it is important to examine how students construct meaning while using such tools. This study examined what fourth grade students learned from the use of two computer-based tools intended to help them understand sound and music: software that emulated an oscilloscope and allowed students to view sound waves from audio input; and software that turned the computer into an electronic keyboard, which provided students with standard pitches for comparison purposes. Principles of selective attention and pior knowledge and experiences—foundational ideas of a constructivist epistemology—were useful in understanding learning outcomes from inquiry with these tools. Our findings provide critical information for future instruction with the goal of supporting learning about sound and music from such tools. They also indicate the need for more studies examining learning from computer-based tools in specific contexts, to advance our understanding of how teachers can mediate student activity with computer-based tools to support the development of conceptual understanding.

  1. Engineering the path to higher-order thinking in elementary education: A problem-based learning approach for STEM integration

    Science.gov (United States)

    Rehmat, Abeera Parvaiz

    As we progress into the 21st century, higher-order thinking skills and achievement in science and math are essential to meet the educational requirement of STEM careers. Educators need to think of innovative ways to engage and prepare students for current and future challenges while cultivating an interest among students in STEM disciplines. An instructional pedagogy that can capture students' attention, support interdisciplinary STEM practices, and foster higher-order thinking skills is problem-based learning. Problem-based learning embedded in the social constructivist view of teaching and learning (Savery & Duffy, 1995) promotes self-regulated learning that is enhanced through exploration, cooperative social activity, and discourse (Fosnot, 1996). This quasi-experimental mixed methods study was conducted with 98 fourth grade students. The study utilized STEM content assessments, a standardized critical thinking test, STEM attitude survey, PBL questionnaire, and field notes from classroom observations to investigate the impact of problem-based learning on students' content knowledge, critical thinking, and their attitude towards STEM. Subsequently, it explored students' experiences of STEM integration in a PBL environment. The quantitative results revealed a significant difference between groups in regards to their content knowledge, critical thinking skills, and STEM attitude. From the qualitative results, three themes emerged: learning approaches, increased interaction, and design and engineering implementation. From the overall data set, students described the PBL environment to be highly interactive that prompted them to employ multiple approaches, including design and engineering to solve the problem.

    Children with high levels of aggressive behavior create a major management problem in school settings and interfere with the learning environment of their classmates. We report results from a group-randomized trial of a program aimed at preventing aggressive behaviors. The purpose of the current study, therefore, was to determine the extent to which an indicated prevention program, Coping Power Program, is capable of reducing behavioral problems and improving pro-social behavior when delivered as a universal classroom-based prevention intervention. Nine classes (five first grade and four second grade) were randomly assigned to intervention or control conditions. Findings showed a significant reduction in overall problematic behaviors and in inattention-hyperactivity problems for the intervention classes compared to the control classes. Students who received Coping Power Program intervention also showed more pro-social behaviors at postintervention. The implications of these findings for the implementation of strategies aimed at preventing aggressive behavior in school settings are discussed.

    Science education traditionally has received insufficient attention. As a literature review shows, teacher preparation in science will be best served by improvements in pedagogy and in the content of required undergraduate science courses. The American Association for the Advancement of Science (1993, 1995) and the National Research Council (1993, 1995) have addressed this need in advocating a "science for all" that is highly significant for diverse learners. The No Child Left Behind Act emphasizes that reform of teacher preparation is part of an urgent national commitment to bring high-quality teacher candidates into the classroom. The Gallaudet University undergraduate teacher education program has developed an inquiry-based course that emphasizes integration of the sciences. Acquisition of the Full Option Science System, and its adaptation to and integration into the course, has resulted in specific curricular changes and positive results.

    Introduction The prevalence of pediatric obesity has increased over the past 3 decades and is a pressing public health program. New technology advancements that can encourage more physical in children are needed. The Zamzee program is an activity meter linked to a motivational website designed for children 8–14 years of age. The objective of the study was to use a collaborative approach between a medical center, the private sector and local school staff to assess the feasibility of using the Zamzee Program in the school-based setting to improve physical activity levels in children. Methods This was a pilot 8-week observational study offered to all children in one fifth grade classroom. Body mass index (BMI), the amount of physical activity by 3-day recall survey, and satisfaction with usability of the Zamzee Program were measured pre- and post-study. Results Out of 11 children who enrolled in the study, 7 completed all study activities. In those who completed the study, the median (interquartile range) total activity time by survey increased by 17 (1042) minutes and the BMI percentile change was 0 (8). Both children and their caregivers found the Zamzee Activity Meter (6/7) and website (6/7) “very easy” or “easy” to use. Conclusion The Zamzee Program was found to be usable but did not significantly improve physical activity levels or BMI. Collaborative obesity intervention projects involving medical centers, the private sector and local schools are feasible but the effectiveness needs to be evaluated in larger-scale studies.

    Full Text Available In this paper we will present the methodology and pedagogy of Elementary Mathematical Modeling as a one-semester course in the liberal arts core. We will focus on the elementary models in finance and business. The main mathematical tools in this course are the difference equations and matrix algebra. We also integrate computer technology and cooperative learning into this inquiry-based learning course where students work in small groups on carefully designed activities and utilize available software to support problem solving and understanding of real life situations. We emphasize the use of graphical and numerical techniques, rather than theoretical techniques, to investigate and analyze the behavior of the solutions of the difference equations.As an illustration of our approach, we will show a nontraditional and efficient way of introducing models from finance and economics. We will also present an interesting model of supply and demand with a lag time, which is called the cobweb theorem in economics. We introduce a sample of a research project on a technique of removing chaotic behavior from a chaotic system.

    Full Text Available Objectives: Overweight and obesity are regarded as one of the most serious health and nutrition issues worldwide. This is immediately recognizable in both children and adolescents. In this study, we aimed to determine the effects of tailored education on lifestyle modification in elementary school students in Isfahan. Methods: In a quasi-experimental study, two elementary schools in Isfahan District 3, Iran, were randomly selected to determine the intervention and comparison groups. Subsequently, 32 students from each school, 64 in total, were chosen arbitrarily and included in the study. They filled out the standardized questionnaire of physical activity and dietary behaviors before the intervention. Following one and four months’ educational intervention, they were asked to complete the questionnaires once more. Results: The average general lifestyle score, one and four months after education, was significantly different between the groups (p < 0.001. However, this difference was not significant before the intervention (p = 0.660. Furthermore, the average lifestyle scores related to nutrition and physical activity one and four months after education showed a significant difference between the groups (p < 0.001. Conclusions: Providing overweight elementary school students with education about a healthy lifestyle improves their general lifestyle and reduces weight. Therefore, it is recommended that such interventions are applied to prevent complications associated with being overweight in children.

    To examine the validity and reliability of a questionnaire administered with an audience response system (ARS). Cross-sectional study. Two New York City public elementary schools. Fourth- and fifth-grade students. A Food, Health, and Choices questionnaire (FHC-Q) assessed energy balance-related behaviors (EBRBs) including intake of fruits and vegetables, sugar-sweetened beverages, processed packaged snacks, and fast food; physical activity; recreational screen time; and associated psychosocial determinants (≥ 3 questions/outcome scale). Previously validated reference instruments were used for relative validation. The ARS format was compared with a paper-and-pencil format. All measures were administered in a classroom setting. Pearson correlation coefficients between the reference instruments and the FHC-Q were calculated. Internal consistency reliabilities were evaluated with Cronbach α. Spearman rank correlation, intra-class correlation, and percent agreement were used for test-retest reliability between paper-and-pencil and ARS, and between 2 ARS FHC-Q administrations. Correlations for EBRBs with reference instruments ranged from 0.38 to 0.61 (P psychosocial determinants. Test-retest reliability correlations ranged from 0.36 to 0.87 (P psychosocial determinants for upper-elementary students. Copyright © 2016 Society for Nutrition Education and Behavior.

    Previously published versions of the healthy eating "FIT Game" were administered by teachers in all grades at elementary schools. The present study evaluated whether the game would retain its efficacy if teachers were relieved of this task; presenting instead all game materials on visual displays in the school cafeteria. Participants were 572 children attending two Title 1 elementary schools (grades K-5). Following a no-intervention baseline period in which fruit and vegetable consumption were measured from food waste, the schools played the FIT Game. In the game, the children's vegetable consumption influenced events in a good versus evil narrative presented in comic book-formatted episodes in the school cafeteria. When daily vegetable-consumption goals were met, new FIT Game episodes were displayed. Game elements included a game narrative, competition, virtual currency, and limited player autonomy. The two intervention phases were separated by a second baseline phase (within-school reversal design). Simulation Modeling Analysis (a bootstrapping technique appropriate to within-group time-series designs) was used to evaluate whether vegetable consumption increased significantly above baseline levels in the FIT Game phases (P Game phases; a 99.9% increase. The Game did not significantly increase fruit consumption (which was not targeted for change), nor was there a decrease in fruit consumption. Labor-reductions in the FIT Game did not reduce its positive impact on healthy eating.

    2012-10-01

    The use of kits in elementary science classes is a growing trend in some countries. Kits provide materials and inquiry lessons in a ready-to-teach format for teachers to use in their science instruction. This study examined elementary teachers' instructional strategies, classroom practices, and assessment types in relation to the frequency of science kit use. A total of 503 elementary teachers from an urban school district received professional development, implemented kits in their classrooms for a year, and then completed a survey about science kit use and teaching practices. Despite similarities in demographic characteristics (gender, ethnicity, certification/educational level), there were significant differences in teachers' use of inquiry-based teaching and assessment practices by kit use. Teachers who reported using kits the most often were significantly more likely to report that their students designed and implemented laboratory investigations as well recorded, represented, and analyzed data. In addition, the high kit users indicated that they were more likely to use student groups, require students to use evidence to support claims, and use alternative assessments of student work including portfolios, notebooks, and long-term projects than those teachers who used kits less frequently. Those teachers who reported using kits the least often were significantly more likely to report having students practice for standardized tests. The role of kits in promoting reform-based teaching practices is discussed.

  17. Preservice Elementary Teachers' Ideas About Scientific Practices

    Ricketts, Amy

    2014-10-01

    With the goal of producing scientifically literate citizens who are able to make informed decisions and reason critically when science intersects with their everyday lives, the National Research Council (NRC) has produced two recent documents that call for a new approach to K-12 science education that is based on scientific practices, crosscutting concepts, and disciplinary core ideas. These documents will potentially influence future state standards and K-12 curricula. Teachers will need support in order to teach science using a practices based approach, particularly if they do not have strong science backgrounds, which is often the case with elementary teachers. This study investigates one cohort (n = 19) of preservice elementary teachers' ideas about scientific practices, as developed in a one-semester elementary science teaching methods course. The course focused on eight particular scientific practices, as defined by the National Research Council's A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012). Participants' written reflections, lesson plans and annotated teaching videos were analyzed in fine detail to better understand their ideas about what it means to engage in each of the practices. The findings suggest that preservice elementary teachers hold promising ideas about scientific practices (such as an emphasis on argumentation and communication between scientists, critical thinking, and answering and asking questions as the goal of science) as well as problematic ideas (including confusion over the purpose of modeling and the process of analysis, and conflating argumentation and explanation building). These results highlight the strengths and limitations of using the Framework (NRC 2012) as an instructional text and the difficulties of differentiating between preservice teachers' content knowledge about doing the practices and their pedagogical knowledge about teaching the practices.

    Promotion of a written narratives production program in the third grade of an Elementary School. To analyze two written narrative practice proposals in order to verify which resources are more efficient in benefitting the textual productions of third grade Elementary School students. Sixty students were selected from two third grade groups of a public Elementary School in São Paulo (Brazil). For the analysis, students were divided into two groups (Group A and Group B). Fourteen children's storybooks were used. In Group A, the story was orally told by the researchers in a colloquial manner, keeping the narrator role and the original structure proposed by the author. In Group B, the story was fully read. The book was projected onto a screen and read aloud so the students could follow the reading and observe the corresponding illustrations. Voice changing resources in the characters' dialogues were used. In the overall comparison, statistically significant results were found for moment (initial and final assessments) and for interaction between groups. It was observed that both groups presented substantial development from initial to final assessment. The Written Narratives Promotion Program based on the shared reading of children's storybooks constituted a more effective strategy than telling the stories using a single reader.

  2. Preservice elementary teachers learning of astronomy

    Science.gov (United States)

    Fidler, Chuck Gary

    The dissertation presents a new approach for the study of preservice elementary teacher astronomy education. The approach suggests that learning astronomical concepts are facilitated by greater sophistication in scale perception and spatial-aptitude. This dissertation is underscored by the national call for elementary science education reform efforts and suggests certain strategies shown more effective for the development of accurate astronomical comprehension. The present research study describes how preservice elementary teachers conceptualize and communicate ideas about Space. Instead of assuming a universal mental conception of cosmic orientations and relationships, the dissertation claims that the perception of Space related dimensions vary among preservice elementary teachers. Furthermore, the dissertation suggests individual perceptions of the scale sizes and orientations of celestial systems have direct influences on mental models used to organize and communicate astronomical information. The development of inaccurate mental models of the scaled dimensions of Space may perpetuate the teacher-student cycle of misconception and naive-theory generation among children in elementary education settings. The ability to conceptualize the vast cosmos is facilitated by the minds ability to think about vast scales and orientations of celestial objects. The Earth-based perspective of astronomy education compels the learner to think about astronomical principles within imaginary frames of reference and across unfamiliar scaled dimensions. Therefore, mental astronomical model building is underscored by the perception of scale and cosmic spatiality. This study suggests these cognitive skill sets are interconnected and facilitate the learning of accurate astronomy principles; as well as play an important role when designing an astronomy education program for preservice elementary teachers. This research study is comprised of three separate standalone articles designed and

    2005-04-01

    The need for increased science exposure at all educational levels continues to be acute. Science is almost universally perceived as difficult, and its ability to raise the quality of life in the presence of apparently insurmountable social problems is increasingly suspect. Over the past 15 years we have conducted teacher workshops, visited classrooms, have organized hands-on demonstration sessions, judged science fairs, and mentored high school students in research efforts, all in an attempt to raise the level of enthusiasm for science. A look ahead suggests that the need continues. Elementary school teachers all too often limit their own science skills to plants and animals, and thus physics concepts do not get the exposure needed to generate the necessary excitement for the physical sciences. Workshops for Elementary grade teachers will be described, which are aimed at preparing teachers to use music as a vehicle to introduce basic physics concepts in the upper elementary grades.

    Over the past 30 years, obesity in the United States has increased twofold in children and threefold in adolescents. In Georgia, nearly 17% of children aged 10 - 17 are obese. In response to the high prevalence of child obesity in Georgia and the potential deleterious consequences that this can have, HealthMPowers was founded in 1999 with the goal of preventing childhood obesity by improving health-enhancing behaviors in elementary schools, utilizing a holistic three-year program. This study measures the effectiveness of the HealthMPowers program in improving the school environment, student knowledge, behavior, cardiovascular fitness levels, and Body Mass Index (BMI). The present analysis utilizes data from 40 schools that worked with HealthMPowers over the course of the 2012 - 2013 school year (including schools at each of the three years of the intervention period) and provided information on demographics, student knowledge and behaviors, BMI, performance on the PACER test of aerobic capacity, and school practices and policies (measured via school self-assessment with the HealthMPowers-developed instrument "Continuous Improvement Tracking Tool" or CITT), measured at the beginning and end of each school year. Paired two-sample T tests were used to compare continuous variables (e.g., student knowledge scores, BMI-for-age Z scores), while chi-squared tests were used to assess categorical variables (e.g., trichotomized PACER performance). Students across all grades and cohorts demonstrated improvements in knowledge and self-reported behaviors, with particularly significant improvements for third-graders in schools in the second year of the HealthMPowers program (p schools tended to improve their practices over time, as measured via the CITT instrument. The present report demonstrates the effectiveness of the HealthMPowers program in producing positive change in school policies and practices, student knowledge and behaviors, and student fitness and BMI, supporting

    2015-03-01

    To examine which school- and home-based factors at age 11 to 12 (6th grade, elementary school) predict physical activity (PA) and sedentary behavior (SB) at age 13 to 14 (8th grade, secondary school). Data at both time points were collected from 472 children (mean age baseline = 10.97, SD age = 0.41) and their parents. Children and parents completed self-reported questionnaires. Children's height and weight were measured and children wore a pedometer for 7 days. Hierarchical regression analyses revealed that predominantly boys (β = -.11), children with higher levels of pedometer-determined PA (β = .44) and more parental logistic support (β = .11) at age 11 to 12 displayed higher levels of pedometer-determined PA at age 13 to 14 (R2 = 39.1%). Similar results emerged for self-reported moderate-to-vigorous PA (R2 = 36.7%). Finally, lower levels of screen-based SB at age 13 to 14 (R2 = 32.5%) were most strongly related to lower levels of screen-based SB (β = .41), a medium/high socioeconomic status (β = -.18), and higher levels of parental PA explicit modeling (β = -.18) at age 11 to 12. Children's PA/SB and the supportive role of parents at age 11 to 12 are strong predictors of PA and screen-based SB at age 13 to 14.

  11. A case study of an experienced teacher's beliefs and practice during implementation of an inquiry-based approach in her elementary science classroom

    Martin, Anita Marie Benna

    The purpose of this study was to examine the relationship between one teacher's beliefs and her practices. This study examined this relationship during the implementation of reform by the teacher in the area of science as recommended by the National Science Education Standards (NRC, 1996). This study was a single case study of one experienced elementary teacher who was implementing the Science Writing Heuristic (SWH) approach in her science classroom. The study's focus was on the relationship between the teacher's beliefs and her practice during this innovation, as well as the factors that influenced that relationship. Data were collected from multiple sources such as routinely scheduled interviews, classroom observations, researcher's fieldnotes, teacher's written reflections, professional development liaison reflections, student responses, video-tape analysis, think-aloud protocol, audio-tapes of student discourse, metaphor analysis, and Reformed Teacher Observation Protocol (RTOP) scores. Data analysis was conducted using two different approaches: constant comparative method and RTOP scores. Results indicate that a central belief of this teacher was her beliefs about how students learn. This belief was entangled with other more peripheral beliefs such as beliefs about the focus of instruction and beliefs about student voice. As the teacher shifted her central belief from a traditional view of learning to one that is more closely aligned with a constructivist' view, these peripheral beliefs also shifted. This study also shows that the teacher's beliefs and her practice were consistent and entwined throughout the study. As her beliefs shifted, so did her practice and it supports Thompson's (1992) notion of a dialectic relationship between teacher beliefs and practice. Additionally, this study provides implications for teacher education and professional development. As teachers implement reform efforts related to inquiry in their science classrooms, professional

    2014-01-01

    In this study, a model that is capable of evaluating the environmental benefits of a new elementary school facility was developed. The model is composed of three steps: (i) retrieval of elementary school facilities having similar characteristics as the new elementary school facility using case-based reasoning; (ii) creation of energy consumption and material data for the benchmark elementary school facility using the retrieved similar elementary school facilities; and (iii) evaluation of the environmental benefits of the new elementary school facility by assessing and comparing the environmental impact of the new and created benchmark elementary school facility using life cycle assessment. The developed model can present the environmental benefits of a new elementary school facility in terms of monetary values using Environmental Priority Strategy 2000, a damage-oriented life cycle impact assessment method. The developed model can be used for the following: (i) as criteria for a green-building rating system; (ii) as criteria for setting the support plan and size, such as the government's incentives for promoting green-building projects; and (iii) as criteria for determining the feasibility of green building projects in key business sectors.

    Full Text Available The study examined age and gender differences in aggression using three representative samples for Slovenia: 4th grade elementary school students; 8th grade elementary school students; 4th grade secondary school students in Matura programs. The results were based on the LA aggression scale that measures general aggression and four specific types of aggression: physical aggression (TA, verbal aggression (BA, internal aggression (NA and aggression towards authority (AA. Based on the results of two-way ANOVA we found important effects of age, gender and their interaction. The gender differences were significant in the groups of elementary school students but not in secondary school students. Male elementary school students, 4th and 8th grade, were more aggressive compared to female elementary school students. 8th grade elementary school students were more physically, verbally, internally aggressive and more aggressive towards authority when compared to 4th grade elementary school students. Secondary school students were significantly less physically and verbally aggressive, and on the other hand more internally aggressive when compared to both groups of elementary school students. Secondary school students reported higher level of aggression towards authority than 4th grade elementary students, and lower level then 8th grade elementary students. The results were congruent with the findings of the research literature indicating higher aggression of males when compared to females and different developmental paths for different types of aggression in question. The study introduced important findings regarding age and gender differences in representative school samples in Slovenia and proposed future research mostly in direction of including measures of indirect aggression that is linked to female gender and older students.

    Full Text Available ABSTRACT It is shown the inexistence of neutrinos to define precisely the concept of relativistics mass under this scheme to elementarys particles as electron and interactions particles like photons correspond an electromagnetic and virtual mass. Nucleons protons and neutrons have real or inertial mass for being composite particles since inertia needs structure it is provided by an interactive network originated by strong and weak forces. This mass is building up atoms and all the material world under Classical Physics and Chemistrys laws.These actual masses may be considered as electromagnetic and virtual one thanks to its charge in order to establish the high energies level needed to obtain all particles physics elementary or not which are governed by the laws of Quantum Physics. With all this one may set up amore reasonable and understandable new Standard Model which being projected into Cosmological Model can get rid of some inconsistencies and concepts difficult to be admitted.

  4. On an elementary definition of visual saliency

    DEFF Research Database (Denmark)

    Loog, Marco

    2008-01-01

    Various approaches to computational modelling of bottom-up visual attention have been proposed in the past two decades. As part of this trend, researchers have studied ways to characterize the saliency map underlying many of these models. In more recent years, several definitions based...... on probabilistic and information or decision theoretic considerations have been proposed. These provide experimentally successful, appealing, low-level, operational, and elementary definitions of visual saliency (see eg, Bruce, 2005 Neurocomputing 65 125 - 133). Here, I demonstrate that, in fact, all...... these characterizations provide essentially the same measure of saliency. Moreover, where the original formulations rely on empirical estimates of the underlying probability density of low-level pre-attentive features, I show that saliency can be expressed as a closed-form solution based on purely local measurements and...

  5. Teaching science as argument: Prospective elementary teachers' knowledge

    Science.gov (United States)

    Barreto-Espino, Reizelie

    For the past two decades there has been increasing emphasis on argumentation in school science. In 2007, the National Research Council published a synthesis report that emphasizes the centrality of constructing, evaluating, and using scientific explanations. Participating in argumentation is seen as fundamental to children's science learning experiences. These new expectations increase challenges for elementary teachers since their understanding of and experiences with science are overwhelmingly inconsistent with teaching science as argument. These challenges are further amplified when dealing with prospective elementary teachers. The current study was guided by the following research questions: (1) What are the ways in which preservice elementary teachers appropriate components of "teaching science as argument" during their student teaching experience? (2) To what extent do components from prospective elementary teachers' reflections influence planning for science teaching? (3) What elements from the context influence preservice elementary teachers' attention to teaching science as argument? This study followed a multi-participant case study approach and analyses were informed by grounded theory. Three participants were selected from a larger cohort of prospective elementary teachers enrolled in an innovative Elementary Professional Development School (PDS) partnership at a large Northeast University. Cross-case analysis allowed for the development of five key assertions: (1) The presence of opportunities for interacting with phenomena and collecting first hand data helped participants increase their emphasis on evidence-based explanations. (2) Participants viewed science talks as an essential mechanism for engaging students in the construction of evidence-based explanations and as being fundamental to meaning-making. (3) Participants demonstrated attention to scientific subject matter during instruction rather than merely focusing on activities and/or inquiry

    This note offers a new point of view on particle masses. It is shown that they are distributed following a musical scale, the chromatic tempered scale -for stable particles- subdivided into microintervals including unstable particles. A theoretical explanation, based on causality, allows one also to calculate their global distribution along the mass scale, in agreement with experiment, and indicating the existence of ''musical'' laws in the vibratory organisation of matter.

    Full Text Available In the article the problem of professional training of future elementary school teacher to teach Informatics of junior schoolchild is revealed. Rapid development of information and communication technologies actualizes the high-quality requirements to informational competent members of society. Transformation of content of primary education, namely putting Informatics in the curricula, exerted impact on a social request of the elementary school teacher who doesn’t only thoroughly use means of information technologies, but also teaches Informatics as invariant discipline of elementary school. In work it is designed the methodical model of training of future elementary school teacher for teaching Informatics, its purpose is forming of methodology informational competence at future elementary school teacher, which is based on theoretical and practical readiness for teaching Informatics of junior schoolchild and is shown in abilities to organize of the teaching and educational process. Finding of a ratio of essential results of training in higher education institution and general and professional competences which were determined by means of expert evaluations became a basis of a substantial component of system. We design the expected result in the form of competence-based model of future elementary school teacher in a perspective of its preparation for the decision the informational and the methodology-informational tasks of elementary school.

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

  18. Preparing perservice teachers to teach elementary school science

    Science.gov (United States)

    Lewis, Amy D.

    The development of scientifically literate citizens begins in the elementary school. Yet elementary school teachers are ill prepared to teach science (Trygstad, Smith, Banilower, Nelson, & Horizon Research, Inc., 2013). The research base on teacher preparation finds that programs designed to prepare elementary teachers are inadequate in providing both the content knowledge and pedagogical content knowledge necessary to teach science effectively (Baumgartner, 2010; Bodzin & Beerer, 2003; Bulunuz & Jarrett 2009). This mixed methods study examined what happened when a science methods course was interactively co-taught by an expert in elementary teaching methods and a physics expert. This study also aimed to discover what aspects of the curriculum pre-service teachers (PSTs) said helped them in developing their understanding of science content and scientific reasoning, and how to implement inquiry practices to teach science. A nested case study of three PSTs provided descriptive portraits of student experiences in the class. A whole class case analysis was used to examine what PSTs learned in terms of science, scientific reasoning skills, and pedagogical content knowledge (PCK) from their experiences in the course. It was found that students often conflated science content with the experiences they had in learning the content. Although PSTs felt the interactive co-teaching model effectively created a balance between theory and practice, it was their experiences doing science--conducting physical experiments, developing and discussing scientific models, and the use of inquiry-based instruction--that they credited for their learning. Even with careful curriculum planning, and a course purposely designed to bridge the theory to practice gap, this study found one semester-long methods course to be insufficient in providing the vast content knowledge and PCK elementary school science teachers need.

  20. The development of elementary quantum theory

    CERN Document Server

    Capellmann, Herbert

    2017-01-01

    This book traces the evolution of the ideas that eventually resulted in the elementary quantum theory in 1925/26. Further, it discusses the essential differences between the fundamental equations of Quantum Theory derived by Born and Jordan, logically comprising Quantum Mechanics and Quantum Optics, and the traditional view of the development of Quantum Mechanics. Drawing on original publications and letters written by the main protagonists of that time, it shows that Einstein’s contributions from 1905 to 1924 laid the essential foundations for the development of Quantum Theory. Einstein introduced quantization of the radiation field; Born added quantized mechanical behavior. In addition, Born recognized that Quantum Mechanics necessarily required Quantum Optics; his radical concept of truly discontinuous and statistical quantum transitions (“quantum leaps”) was directly based on Einstein’s physical concepts.

    Suescun-Florez, Eduardo; Iskander, Magued; Kapila, Vikram; Cain, Ryan

    2013-06-01

    This paper reports on the results of several geotechnical engineering-related science activities conducted with elementary-school students. Activities presented include soil permeability, contact stress, soil stratigraphy, shallow and deep foundations, and erosion in rivers. The permeability activity employed the LEGO NXT platform for data acquisition, the soil profile and foundations activity employed natural and transparent soils as well as LEGO-based foundation models, and the erosion activity utilised a 3D printer to assist with construction of building models. The activities seek to enhance students' academic achievement, excite them about geotechnical engineering, and motivate them to study science and math. Pre- and post-activity evaluations were conducted to assess both the suitability of the activities and the students' learning. Initial results show that students gain a reasonable understanding of engineering principles. Moreover, the geotechnical engineering activities provided students an opportunity to apply their math skills and science knowledge.

    A simple, highly-automated instrument system used for on-site detection of foodborne pathogens based on fluorescence was designed, fabricated, and preliminarily tested in this paper. A corresponding method has been proved effective in our previous studies. This system utilizes a light-emitting diode (LED) to excite fluorescent labels and a spectrometer to record the fluorescence signal from samples. A rotation stage for positioning and switching samples was innovatively designed for high-throughput detection, ten at most in one single run. We also developed software based on LabVIEW for data receiving, processing, and the control of the whole system. In the test of using a pure quantum dot (QD) solution as a standard sample, detection results from this home-made system were highly-relevant with that from a well-commercialized product and even slightly better reproducibility was found. And in the test of three typical kinds of food-borne pathogens, fluorescence signals recorded by this system are highly proportional to the variation of the sample concentration, with a satisfied limit of detection (LOD) (nearly 10²-10³ CFU·mL -1 in food samples). Additionally, this instrument system is low-cost and easy-to-use, showing a promising potential for on-site rapid detection of food-borne pathogens.

  10. Young elementary students' conceptual understandings of lunar phases before and after an inquiry-based and technology-enhanced instructional intervention

    Science.gov (United States)

    Hobson, Sally Merryman

    This mixed methods study explored young children's understandings of targeted lunar concepts, including when the moon can be observed, observable lunar phase shapes, predictable lunar patterns, and the cause of moon phases. Twenty-one children (ages seven to nine years) from a multi-aged classroom participated in this study. Data were collected using semi-structured interviews, student drawings, and card sorting before and after an inquiry-based, technology-enhanced instructional intervention. Students' lunar calendars, written responses, field notes, and videotaped class sessions also provided data throughout the study. Data were analyzed using codes from prior lunar studies, constant comparative analysis, and nonparametric analysis. The instructional intervention included lunar data gathering, recording, and sharing, through the use of Starry Night planetarium software and an inquiry-based instruction on moon phases (McDermott, 1996). In a guided inquiry context children worked in groups to gather and analyze nine weeks of lunar data. Findings indicated a positive change in students' understanding of all targeted concepts. After the intervention more children understood that the moon could be observed sometimes during the day, more children drew scientific moon phase shapes, and more children drew scientific representations of the moon phase sequences. Also, more children understood the cause of moon phases.

    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.

    2008-02-20

    The catalytic hydrogenation of benzaldehyde and acetophenone with the Shvo hydrogenation catalysts were monitored by in situ IR spectroscopy in both toluene and THF. The disappearance of organic carbonyl compound and the concentrations of the ruthenium species present throughout the hydrogenation reaction were observed. The dependence of the hydrogenation rate on substrate, H2 pressure, total ruthenium concentration, and solvent were measured. In toluene, bridging diruthenium hydride 1 was the only observable ruthenium species until nearly all of the substrate was consumed. In THF, both 1 and some monoruthenium hydride 2 were observed during the course of the hydrogenation. A full kinetic model of the hydrogenation based on rate constants for individual steps in the catalysis was developed. This kinetic model simulates the rate of carbonyl compound hydrogenation and of the amounts of ruthenium species 1 and 2 present during hydrogenations.

    The present study investigates the effectiveness of a family-based, online media literacy education (MLE) program for substance abuse prevention in children from rural areas. A total of 83 families were randomly assigned to receive Media Detective Family (MDF) (n = 47) or a control computer program (n = 36) between pre- and posttest questionnaires. Fifty-one percent (N=42) completed a three-month follow-up questionnaire. Children receiving MDF reported a significant reduction in their use of substances over time compared to children in the control group (d = -.80). Parents receiving MDF reported that the program was convenient and engaging. The current study showed that an online substance use prevention program using MLE and designed for families is an effective intervention method for reducing children's substance use.

Eighty-six preservice elementary teachers participated in this study. Twelve preservice elementary teachers participated in follow-up interviews. Data were collected through the use of Alternative Conceptions in Science Instrument (Schoon, & Boone, 1998, a participant information form, and utilization of interviews. The results indicated that the majority of preservice elementary teachers (67.4% held a number of alternative conceptions with mostly in the physical science. Various sources of alternative conceptions emerged during the interviews. Findings from the study also confirmed that science courses completed do not seem to have influenced participants’ alternative conceptions. Overall, the results of the study suggest that more consideration be given to identifying and modifying of the alternative conceptions of science so that teachers could better help their own students arriving at more accurate conceptions.

  11. A full computation-relevant topological dynamics classification of elementary cellular automata.

    2012-12-01

    Cellular automata are both computational and dynamical systems. We give a complete classification of the dynamic behaviour of elementary cellular automata (ECA) in terms of fundamental dynamic system notions such as sensitivity and chaoticity. The "complex" ECA emerge to be sensitive, but not chaotic and not eventually weakly periodic. Based on this classification, we conjecture that elementary cellular automata capable of carrying out complex computations, such as needed for Turing-universality, are at the "edge of chaos."

    Full Text Available This study aims to verify how students in elementary school see themselves in relation to mathematics and, at the same time, analyze the procedures used to solve algebraic tasks. These students in the 8th year of elementary school, and first and third years of high school, from two State schools in Passo Fundo/RS, answered a questionnaire about their own perceptions of the mathematics lessons, the subject mathematics and algebraic content. The analysis was based mainly on authors from the athematical education and the historic-cultural psychology areas. It was verifi ed that even among students who claimed to be happy with the idea of having mathematicsclasses several presented learning diffi culties regarding algebraic contents, revealed by the procedures employed. It was concluded that it is necessary to design proposals with didactic sequences, mathematically and pedagogically based, which can effi cientlyoptimize the appropriation of meaning from the concepts approached and their application in different situations.

Our specific research questions were (1) What ideas do elementary preservice teachers bring to a science teaching methods course about the inquiry continuum? and (2) How do their ideas about the inquiry continuum change over the course of the semester through engaging in planning, enactment, and reflection upon science instruction? Participants' course artifacts (journals, reflective teaching assignments, and lesson plan rationales), interviews, and field observations of their enacted science lessons served as data for this study. Findings show that although the preservice teachers began the semester defining inquiry as highly student-directed, their ideas and definitions broadened over the course of the semester to include and embrace more teacher-directed forms of inquiry. Their early science lessons were more student-directed but, as they encountered challenges engaging in inquiry-based instruction and increasingly emphasized students' learning needs, they began to plan and enact lessons that were more teacher-directed. Teacher education programs need to explicitly emphasize these variations of inquiry as a core component of supporting preservice teachers' learning to teach science as inquiry.

    This study examined elementary teachers' instructional strategies for promoting scientific understanding and inquiry and supporting English language development with diverse student groups including English language learners. The study was part of a 5-year research and development project consisting of reform-based science curriculum units and teacher workshops aimed at providing effective science instruction to promote students' science and literacy achievement in urban elementary schools. Data consisted of 213 post-observation interviews with third, fourth, and fifth grade teachers. The teachers reported using instructional strategies to promote scientific understanding, but generally did not employ more sophisticated inquiry-based strategies. They also reported using instructional strategies to support English language development. There were significant differences among grade levels and by years of teacher participation.

    Elementary flux modes (EFMs) emerged as a formal concept to describe metabolic pathways and have become an established tool for constraint-based modeling and metabolic network analysis. EFMs are characteristic (support-minimal) vectors of the flux cone that contains all feasible steady-state flux vectors of a given metabolic network. EFMs account for (homogeneous) linear constraints arising from reaction irreversibilities and the assumption of steady state; however, other (inhomogeneous) linear constraints, such as minimal and maximal reaction rates frequently used by other constraint-based techniques (such as flux balance analysis [FBA]), cannot be directly integrated. These additional constraints further restrict the space of feasible flux vectors and turn the flux cone into a general flux polyhedron in which the concept of EFMs is not directly applicable anymore. For this reason, there has been a conceptual gap between EFM-based (pathway) analysis methods and linear optimization (FBA) techniques, as they operate on different geometric objects. One approach to overcome these limitations was proposed ten years ago and is based on the concept of elementary flux vectors (EFVs). Only recently has the community started to recognize the potential of EFVs for metabolic network analysis. In fact, EFVs exactly represent the conceptual development required to generalize the idea of EFMs from flux cones to flux polyhedra. This work aims to present a concise theoretical and practical introduction to EFVs that is accessible to a broad audience. We highlight the close relationship between EFMs and EFVs and demonstrate that almost all applications of EFMs (in flux cones) are possible for EFVs (in flux polyhedra) as well. In fact, certain properties can only be studied with EFVs. Thus, we conclude that EFVs provide a powerful and unifying framework for constraint-based modeling of metabolic networks. PMID:28406903

    2017-01-01

    This book provides a comprehensive, in-depth overview of elementary mathematics as explored in Mathematical Olympiads around the world. It expands on topics usually encountered in high school and could even be used as preparation for a first-semester undergraduate course. This first volume covers Real Numbers, Functions, Real Analysis, Systems of Equations, Limits and Derivatives, and much more. As part of a collection, the book differs from other publications in this field by not being a mere selection of questions or a set of tips and tricks that applies to specific problems. It starts from the most basic theoretical principles, without being either too general or too axiomatic. Examples and problems are discussed only if they are helpful as applications of the theory. Propositions are proved in detail and subsequently applied to Olympic problems or to other problems at the Olympic level. The book also explores some of the hardest problems presented at National and International Mathematics Olympiads, as we...

    This study examined the impact of an inquiry-based instructional intervention on (a) children's ability to conduct science inquiry overall and to use specific skills in inquiry, and (b) narrowing the gaps in children's ability among demographic subgroups of students. The intervention consisted of instructional units, teacher workshops, and classroom practices. The study involved 25 third- and fourth-grade students from six elementary schools representing diverse linguistic and cultural groups. Quantitative results demonstrated that the intervention enhanced the inquiry ability of all students regardless of grade, achievement, gender, ethnicity, socioeconomic status (SES), home language, and English proficiency. Particularly, low-achieving, low-SES, and English for Speakers of Other Languages (ESOL) exited students made impressive gains. The study adds to the existing literature on designing learning environments that foster science inquiry of all elementary students.

    This study was an exploration of the conceptions of inquiry science held by exemplary elementary teachers. The origins of these conceptions were explored in order to establish how best to improve elementary teachers' understanding and implementation of inquiry science teaching. Four focus group sessions were held as well as classroom observations. Data were also collected through surveys and interviews. The six exemplary teachers in this study held ideas about inquiry as "finding things out" and all described themselves as having been children who explored and experimented with the world around them. The teachers provided information about successful classroom environments and attitudes that they use to achieve strong inquiry science learning. The teachers had a number of recommendations for helping other teachers become inquiry science teachers and suggestions for professional development for teachers are made based on these recommendations.

    Hulings, Melissa

    This study sought to understand how science learning experiences, and their potential influence, had on preservice elementary teachers' self-efficacy and perceptions of science teaching and learning at the beginning of their science methods course. Following an explanatory sequential mixed methods design, this study first involved the collection of quantitative data and then the collection of more in-depth qualitative data. In the first phase, the quantitative data included the Draw-a-Science-Teacher-Test Checklist (DASTT-C) and the Science Teaching Efficacy Belief Instrument (STEBI-B) of preservice elementary teachers (n = 69). Findings from this phase indicated preservice elementary teachers had a higher level of belief in their abilities to teach science (PSTE subscale) than to affect student outcomes in science (STOE subscale). However, the STOE was not found to be a reliable measure for this group of preservice elementary teachers and was not included in any further analysis. Findings from the DASTT-C images indicated the majority of these drawings could not be classified as student-centered. In the second phase of this study, the researcher explored selected science autobiographies written by these same preservice elementary teachers (n = 19), based on extremely high or low scores on the PSTE subscale and DASTT-C. Analysis of the science autobiographies revealed commonalities and differences. Commonalities included (a) the difficulty in remembering science from elementary school; (b) a mixture of positive and negative experiences in secondary school and college science classes; (c) the descriptions of good science days and good science teachers; and (d) the descriptions of bad science days and bad science teachers. Differences included (a) the people who influenced their attitudes toward science; (b) the types of experiences, when remembered, from elementary school; and (c) visions of their future classrooms. Based on these findings, these preservice

    2011-09-01

    This study explored practicing elementary school teacher's conceptions of teaching in ways that foster inquiry-based learning in the science curriculum (inquiry teaching). The advocacy for inquiry-based learning in contemporary curricula assumes the principle that students learn in their own way by drawing on direct experience fostered by the teacher. That students should be able to discover answers themselves through active engagement with new experiences was central to the thinking of eminent educators such as Pestalozzi, Dewey and Montessori. However, even after many years of research and practice, inquiry learning as a referent for teaching still struggles to find expression in the average teachers' pedagogy. This study drew on interview data from 20 elementary teachers. A phenomenographic analysis revealed three conceptions of teaching for inquiry learning in science in the elementary years of schooling: (a) The Experience-centered conception where teachers focused on providing interesting sensory experiences to students; (b) The Problem-centered conception where teachers focused on engaging students with challenging problems; and (c) The Question-centered conception where teachers focused on helping students to ask and answer their own questions. Understanding teachers' conceptions has implications for both the enactment of inquiry teaching in the classroom as well as the uptake of new teaching behaviors during professional development, with enhanced outcomes for engaging students in Science.

    Harris, Mary Sadama

    This research sought to determine whether and how current local and national curricular mandates affect the science instruction of two exemplary Alabama elementary teachers. The study provides a description of the contextual backdrop of elementary teaching in Alabama and the curricular mandates resulting from federal legislation entitled The No Child Left Behind Act of 2001 that have been enacted across the state of Alabama. This study centers on the evolution of reform initiatives that impact the teaching of science in elementary schools. These reforms focus on student achievement, teacher accountability, subject matter testing, and federal legislation. The emphasis on accountability has created situations where teachers are, in any given year, faced with multiple program innovations focused on subject matter tested leaving other subjects areas such as science excluded from the curricula. Reform initiatives influential to this research were the Alabama Reading Initiative and Alabama's State Department of Education's mandated testing and progress monitoring of the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) and how these reforms impact the elementary day and science instruction. The purpose of this research, which utilized a qualitative multiple case study design, was to understand how exemplary elementary science teachers in Alabama teach science given the curricular mandates that marginalize science instructional time. The central phenomenon centered on the curricular adaptations and negotiations teachers made in order to teach science. Data collected included classroom observations, semi-structured interviews, and artifacts. An inductive, interpretative approach to data analysis was used to allow for exploration of the sociocultural and sociopolitical influences on science teaching of these exemplary elementary teachers. Findings were constructed as narrative portraitures of each teacher and their science teaching bounded within their unique

    Elementary flows are essential components of data used for life cycle assessment. A standard list is not used across all sources, as data providers now manage these flows independently. Elementary flows must be consistent across a life cycle inventory for accurate inventory analysis and must correspond with impact methods for impact assessment. With the goal of achieving a global network of LCA databases, a critical review of elementary flow usage and management in LCA data sources was performed. Flows were collected in a standard template from various life cycle inventory, impact method, and software sources. A typology of elementary flows was created to identify flows by types such as chemicals, minerals, land flows, etc. to facilitate differential analysis. Twelve criteria were defined to evaluate flows against principles of clarity, consistency, extensibility, translatability, and uniqueness. Over 134,000 elementary flows from five LCI databases, three LCIA methods, and four LCA software tools were collected and evaluated from European, North American, and Asian Pacific LCA sources. The vast majority were typed as "Element or Compound" or "Group of Chemicals" with less than 10% coming from the other seven types Many lack important identifying information including context information (environmental compartments), directionality (LCIA methods generally do not provide this information), additional clarifiers such as CAS numbers and synonyms, unique identifiers (like UUIDs), and supporting metadata. Extensibility of flows is poor because patterns in flow naming are generally complex and inconsistent because user defined nomenclature is used. The current shortcomings in flow clarity, consistency, and extensibility are likely to make it more challenging for users to properly select and use elementary flows when creating LCA data and make translation/conversion between different reference lists challenging and loss of information will likely occur.

    Modern physics lacks a unitary theory that applies to all four fundamental interactions. This PhD thesis is a proposal for a single, complete, and coherent scheme of mathematically formulated elementary laws of nature. While the first chapter presents the general background, the second chapter addresses the method by which the main result has been developed. The next three chapters rigorously introduce the Elementary Process Theory, its mathematical foundations, and its applications to physics, cosmology and philosophy of mind. The final two chapters discuss the results and present the conclusions. Summarizing, the Elementary Process Theory is a scheme of seven well-formed closed expressions, written in the mathematical language of set matrix theory – a generalization of Zermelo-Fraenkel set theory. In the physical world, these seven expressions can be interpreted as elementary principles governing the universe at supersmall scale. The author critically confronts the theory with Quantum Mechanics and Genera...

    The study provides evidence concerning elementary school children's ability to conduct a scientific investigation. Two hundred and fifty sixth-grade students and 248 fourth-grade students were administered a test, and based on their performance, they were classified into high-ability and low-ability students. The sample of this study was randomly selected and included 80 students, 40 fourth-grade and 40 sixth-grade students of low and high abilities. Students were specifically instructed to investigate the functioning of a device, to think aloud prior and after any experiment with the device, and to keep a record of their experimental results. The results showed that students were inclined to mainly collect evidence from the experimental space and failed to control variables during their investigation. The majority of the students had difficulties with effectively organizing collected data and failed to coordinate hypotheses with evidence. The significant interaction effect that was found between grade level and ability in terms of students' investigation ability indicates that the existing gap between high- and low-ability students becomes bigger as students become older. Undoubtedly, ongoing research efforts for identifying patterns of children's cognitive development will be most valuable as they can have important implications for the design of teaching scenarios and inquiry-based science activities conducive to accelerating students' cognitive growth and scientific investigation abilities.

    Full Text Available Background: Hand washing is the most effective method of preventing the transmission of diseases through hands. Objective: To identify relationships between gender, availability of hand washing facilities, perception of barriers toward hand washing compliance and subjective norm in implementing hand washing practice among students of public elementary school in Belitung district, Indonesia. Method: A cross-sectional research study was used in this study. Of 309 participants were recruited in 11 public elementary schools from 3 sub districts that has been implemented the hand washing program in Belitung, Indonesia. Purposive sampling method was used to select the participants. This study was used a self-administered questionnaire with minimal interference in order to minimize bias and by emphasizing to the students that this is not an examination. Results: The results showed that 71.8% of the students were not hand washing properly. It also showed that availability of hand washing facilities and gender were not related with hand washing behavior. In regards of barrier perception toward hand washing compliance also showed that was not related to hand washing practice among elementary schools students. However, subjective norm (χ² =4.459, p < .05 was related to hand washing practice among elementary schools students. Conclusion: Subjective norm has a significant relationship to hand washing behavior. Thus health care provider could develop specific intervention programs based on TPB to promote subjective norm among elementary schools students since this norm or perception of norm can motivate hand washing behavior among elementary schools students effectively.

    Early school withdrawal, commonly referred to as dropout, is associated with a plethora of negative outcomes for students, schools, and society. Student engagement, however, presents as a promising theoretical model and cornerstone of school completion interventions. The purpose of the present study was to validate the Student Engagement Instrument-Elementary Version (SEI-E). The psychometric properties of this measure were assessed based on the responses of an ethnically diverse sample of 1,943 students from an urban locale. Exploratory and confirmatory factor analyses indicated that the 4-factor model of student engagement provided the best fit for the current data, which is divergent from previous SEI studies suggesting 5- and 6-factor models. Discussion and implications of these findings are presented in the context of student engagement and dropout prevention. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

    2013-06-01

    While a solid understanding of science content knowledge is important in developing expertise in science teaching, it is not necessarily a sufficient condition to teach science effectively in elementary schools. Teachers need to have the ability to transform their knowledge into forms learnable by students. Based on this perspective, the current study explored how science content knowledge was pedagogically transformed in Korean elementary classrooms. Data sources included video-recorded science lessons of five elementary teachers in a metropolitan city of Korea. The analysis of the data revealed that the Korean teachers often engaged in transforming science content knowledge by means of different semiotic modes, including language, pictures, materials, actions, and their complex combinations. Further, their representations of scientific knowledge were in diverse forms, such as personifications, analogies, quiz questions, pictorial models, diagrams, animations, real-life examples, hand demonstrations, videos, flash tools, and songs-and-dances. Future research involving a wider range of participants, such as students, content specialists, and teachers with weak and strong content understanding, was suggested to confirm the findings of this study and find more various ways of pedagogical transformation of science subject matter knowledge.

    The PISCES Project (Partnerships Involving the Scientific Community in Elementary Schools) is an NSF G-K12 funded initiative that is in its fouth year of funding. In the Project graduate students from San Diego State University, California State University San Marcos, and University of California San Diego partner with San Diego area elementary school teachers to immerse students in hands-on standards-based elementary science curriculum. The project has grown from 24 teachers representing 7 school districts and 10 Science Corps Fellows (graduate students), to over 100 teachers from 14 districts and 22 Fellows. During the second project year, Fellows interacted for over 10,000 hours with K-12 students. This close interaction, coupled with high quality, ongoing professional development for teachers and intensive outreach efforts has resulted in increased student enthusiasm for science from K-6 students, an appreciation of the importance of high quality science education from Fellows, and improved commitment by teachers to utilize hands-on science materials.

    2015-01-01

    The purpose of this case study was to explore the ways in which 3 different informal science experiences in the context of an elementary methods course influenced a group of prospective elementary teachers' ideas about science teaching and learning as well as their understandings about the role of informal science environments to teaching and learning. In order to address this question, data were collected in a period of an academic semester through the following sources: journal entries for each of the 3 experiences, a personal teaching philosophy statement and a 2-hour long semi-structured interview with each of the 12 participants. Open coding techniques were used to analyze the data in order to construct categories and subcategories and eventually to identify emerging themes. The outcomes of the analysis showed that the inclusion of informal science experiences in the context of teacher preparation has the potential to support beginning elementary teachers' development of contemporary ideas about science teaching and learning related to inquiry-based science, the nature of scientific work and the work of scientists, connecting science with everyday life, and making science fun and personally meaningful. These findings are discussed alongside implications for policy, teacher preparation, and research under these themes: (a) addressing reform recommendations; (b) developing positive orientations toward science and science teaching; and (c) constructing understandings about scientists' work.

  18. Examining student-generated questions in an elementary science classroom

    Diaz, Juan Francisco, Jr.

    This study was conducted to better understand how teachers use an argument-based inquiry technique known as the Science Writing Heuristic (SWH) approach to address issues on teaching, learning, negotiation, argumentation, and elaboration in an elementary science classroom. Within the SWH framework, this study traced the progress of promoting argumentation and negotiation (which led to student-generated questions) during a discussion in an elementary science classroom. Speech patterns during various classroom scenarios were analyzed to understand how teacher--student interactions influence learning. This study uses a mixture of qualitative and quantitative methods. The qualitative aspect of the study is an analysis of teacher--student interactions in the classroom using video recordings. The quantitative aspect uses descriptive statistics, tables, and plots to analyze the data. The subjects in this study were fifth grade students and teachers from an elementary school in the Midwest, during the academic years 2007/2008 and 2008/2009. The three teachers selected for this study teach at the same Midwestern elementary school. These teachers were purposely selected because they were using the SWH approach during the two years of the study. The results of this study suggest that all three teachers moved from using teacher-generated questions to student-generated questions as they became more familiar with the SWH approach. In addition, all three promoted the use of the components of arguments in their dialogs and discussions and encouraged students to elaborate, challenge, and rebut each other's ideas in a non-threatening environment. This research suggests that even young students, when actively participating in class discussions, are capable of connecting their claims and evidence and generating questions of a higher-order cognitive level. These findings demand the implementation of more professional development programs and the improvement in teacher education to help

    The link between chemical orbitals described by local degrees of freedom and band theory, which is defined in momentum space, was proposed by Zak several decades ago for spinless systems with and without time reversal in his theory of "elementary" band representations. In a recent paper [Bradlyn et al., Nature (London) 547, 298 (2017), 10.1038/nature23268] we introduced the generalization of this theory to the experimentally relevant situation of spin-orbit coupled systems with time-reversal symmetry and proved that all bands that do not transform as band representations are topological. Here we give the full details of this construction. We prove that elementary band representations are either connected as bands in the Brillouin zone and are described by localized Wannier orbitals respecting the symmetries of the lattice (including time reversal when applicable), or, if disconnected, describe topological insulators. We then show how to generate a band representation from a particular Wyckoff position and determine which Wyckoff positions generate elementary band representations for all space groups. This theory applies to spinful and spinless systems, in all dimensions, with and without time reversal. We introduce a homotopic notion of equivalence and show that it results in a finer classification of topological phases than approaches based only on the symmetry of wave functions at special points in the Brillouin zone. Utilizing a mapping of the band connectivity into a graph theory problem, we show in companion papers which Wyckoff positions can generate disconnected elementary band representations, furnishing a natural avenue for a systematic materials search.

  20. Investigating a redesigned physics course for future elementary teachers

    Science.gov (United States)

    Fracchiolla, Claudia

    There is a growing concern that the number of students graduating with a STEM major in the U.S. is insufficient to fill the growing demand in STEM careers. In order to fulfill that demand, it is important to increase student retention in STEM majors and also to attract more students to pursue careers in those areas. Previous research has indicated that children start losing interest in science at the elementary level because science is taught with a focus on learning vocabulary and ideas rather than learning through inquiry-based techniques. A factor that affects the quality of science education at the elementary level is the preparation of elementary teachers. Many elementary teachers feel unprepared to teach science because they lack adequate content knowledge as well as the pedagogical content knowledge (PCK) for teaching the subject. Previous studies of teacher preparation in science identified some areas with which pre-service teachers need assistance. One of these areas is understanding children's ideas of science. To address that issue, this dissertation investigates whether the use of an instructional approach that teaches physics phenomena along with an understanding of how children think about the physical phenomena promotes changes in students' knowledge of children's ideas and use of those ideas in instructional and assessment strategies. Results indicated that students who were explicitly exposed to knowledge of children's ideas more often incorporated those ideas into their own microteaching and demonstrated higher levels of sophistication of knowledge of children's ideas, instructional strategies, and assessment strategies that incorporated those ideas. This research explores an instructional model for blending physics content and pedagogical content knowledge.

  1. Making space more interesting to elementary students

    Edlund, J.

    When in life do we take the big decision of deciding which path in our career we are going to take? Is this decision made from our experiences in school or is it taken before? Do our family or our friends hopes and dreams for us have any impact on our decision? These are questions that are useful for understanding why some people choose to work with science and why other has chosen another career. In my work to help the university to recruit new student to their master of science in space engineering programme, I have been visiting an elementary school and talked about different topics in space science. The pupils were very interested but when I did a survey of their dream jobs and future career I saw that most of them have hopes of a career that are based on their present talent and not on what education they are going to have. 11 out of 17 students that did this survey wanted to be some kind of artist or soccer professional. Only 4 of them had chosen a career that there are educations for. I do not think this is the situation only for this school, I think this situation is common for children I this age. Since the chance of being a pro in any sport is a really hard thing, probably the most of them have to give up their dream and chose a more realistic approach to their future career. This leaves us with a majority of the students that have not yet had their path chosen and hopefully with help of teachers and special lectures we can make science more attractive to them. This sound like an easy problem, since most of the students finds space really interesting. But there are some problems. The teachers do not have the kind of education, especially in elementary school that is needed for the kids to get proper answer to their questions. The solution is not easy. Should the teachers take more courses in physics and chemistry or should it be their responsibility to search for facts when these kinds of questions appear? I found that in some cases the student have

    Full Text Available The author analyzes the problem of literary education of elementary school students in the contemporary cultural space. The article states that the literary education based on literary Propedevtics of younger students and is based on the process of reading fiction. Therefore, it is important to promote reading, promote children's reading and children's book production in Ukraine. The author concludes that the gradual renewal of the education system, particularly literary education of primary school children should be primarily seen in the development of new textbooks and anthologies that will meet the needs and opportunities of the modern child.

    Although spatial ability and mathematics performance are highly correlated, there is scant research on the extent to which spatial ability training can improve mathematics performance. This study evaluated the efficacy of a visuospatial intervention programme within classrooms to determine the effect on students' (1) spatial reasoning and (2) mathematics performance as a result of the intervention. The study involved grade six students (ages 10-12) in eight classes. There were five intervention classes (n = 120) and three non-intervention control classes (n = 66). A specifically designed 10-week spatial reasoning programme was developed collaboratively with the participating teachers, with the intervention replacing the standard mathematics curriculum. The five classroom teachers in the intervention programme presented 20 hr of activities aimed at enhancing students' spatial visualization, mental rotation, and spatial orientation skills. The spatial reasoning programme led to improvements in both spatial ability and mathematics performance relative to the control group who received standard mathematics instruction. Our study is the first to show that a classroom-based spatial reasoning intervention improves elementary school students' mathematics performance. © 2017 The British Psychological Society.

    Traveling Science is an elementary science visitation program by two high school teachers (using scheduled release time) for every third to fifth grade student and teacher in Granville County, North Carolina (a total of sixty-one classes, 1,600 students-over 25,000 student contacts in three years). Teachers and students see and participate in hands-on, inquiry-based science done with inexpensive, readily available materials (usually less than 2% per class). Teachers become more confident and self-reliant with respect to science education, and students get increased exposure to hands-on science. In addition to the classroom visits (a total of six per year for each class), teachers receive a guide containing introductory and follow-up materials, and a monthly newsletter. Visit topics cover the physical, life and earth sciences; designed to stress the processes of science. We try to use topics of interest and relevance to students, such as toys, food, animals and playground activities. Teachers and schools also receive additional materials (posters and videos).

  7. A narrative study of novice elementary teachers' perceptions of science instruction

    Science.gov (United States)

    Harrell, Roberta

    It is hoped that, once implemented, the Next Generation Science Standards (NGSS) will engage students more deeply in science learning and build science knowledge sequentially beginning in Kindergarten (NRC, 2013). Early instruction is encouraged but must be delivered by qualified elementary teachers who have both the science content knowledge and the necessary instructional skills to teach science effectively to young children (Ejiwale, 2012, Spencer, Vogel, 2009, Walker, 2011). The purpose of this research study is to gain insight into novice elementary teachers' perceptions of science instruction. This research suggests that infusion of constructivist teaching in the elementary classroom is beneficial to the teacher's instruction of science concepts to elementary students. Constructivism is theory that learning is centered on the learner constructing new ideas or concepts built upon their current/past knowledge (Bruner, 1966). Based on this theory, it is recommended that the instructor should try to encourage students to discover principles independently; essentially the instructor presents the problem and lets students go (Good & Brophy, 2004). Discovery learning, hands-on, experimental, collaborative, and project-based learning are all approaches that use constructivist principles. The NGSS are based on constructivist principles. This narrative study provides insight into novice elementary teachers' perceptions of science instruction considered through the lens of Constructivist Theory (Bruner, 1960).

    On 19 April 2011, the Ministry of Education, Culture, Sports, Science, and Technology designated 13 elementary schools, including Tominari Elementary School in Date city, as high-dose schools that needed to restrict outdoor activities due to the effects of the accident at Fukushima Daiichi nuclear power plant. Approximately 1 week later, the municipal government took action to remove the topsoil from the school grounds, and the prohibition of outdoor activities at Tominari Elementary School was lifted. The school staff continued to work on decontaminating the surrounding areas using high-pressure washers and brushes. There were certain positive outcomes, but a more effective decontamination method was required. In July 2011, the municipal government started an environmental remediation project, both inside and outside the school buildings, with researchers and decontamination workers at Tominari Elementary School, involving members of the Parent-Teacher Association (PTA), local communities, and volunteers using various effective and specialised forms of decontamination. As a result, Tominari Elementary School was able to recommence swimming lessons at the end of the first semester, which had been thought to be impossible. This article will provide information about the importance of 'dialogue' for decontamination, how engagement of the experts gave members of the PTA and the local community a feeling of 'security and safety', and how the decontamination work was an ever-expanding collaborative work of a large number of people.

  9. The effect of a nontraditional undergraduate science course on teacher and student performance in elementary science teaching

    Staples, Kimberly Ardena

    This study investigated the differential effects of experiences in nontraditional and traditional undergraduate science courses on the science teaching and learning of undergraduate education majors, elementary classroom teachers, and students. The ability for teachers to demonstrate knowledge through inquiry, critical analysis, and synthesis of the subject is clearly articulated as a requirement in the National Science Education Standards (National Research Council, 1996) and the National Accreditation of Teacher Education (2000). To meet this goal, science instruction in higher education requires reform to effectively prepare elementary undergraduate education majors in science content. The research study included a sample of 264 participants from a single university that represented undergraduate education majors, college science instructors, elementary classroom teachers, and elementary classroom students. Short term and long term learning outcomes of undergraduate education majors and classroom teachers were evaluated for the effect of experiences in a nontraditional college science course. Quantitative and qualitative data were collected through questionnaires, standardized tests, surveys, oral and written interviews, and observations of undergraduate and elementary science lessons. A triangulation of the data results revealed that modeling, active engagement, project-based activities, and cooperative learning positively affected undergraduate education majors' science teaching efficacy, science content mastery, and elementary teacher performance in science classroom instruction. Standardized test scores revealed higher achievement in science among elementary students of teachers experienced in a nontraditional science course than students of teachers experienced only in traditional learning environments. The results of this study support the call for reform in college science teaching. The standards based context in which science content was delivered

    2014-09-01

    Radiostereometric analysis (RSA) is the gold standard of measurement for in vivo 3D implants migration. The aim of this study was to evaluate the in vivo precision of 2 RSA marker-based systems compared with that of marker-free, elementary geometrical shape modeling RSA. Stem migration was measured in 50 patients recruited from an on-going Randomized Controlled Trial. We performed marker-based analysis with the Um RSA and RSAcore systems and compared these results with those of the elementary geometrical shape RSA. The precision for subsidence was 0.118 mm for Um RSA, 0.141 mm for RSAcore, and 0.136 mm for elementary geometrical shape RSA. The precision for retroversion was 1.3° for elementary geometrical shape RSA, approximately 2-fold greater than that for the other methods. The intraclass correlation coefficient between the marker-based systems and elementary geometrical shape RSA was approximately 0.5 for retroversion. All 3 methods yielded ICCs for subsidence and varus-valgus rotation above 0.9. We found an excellent correlation between marker-based RSA and elementary geometrical shape RSA for subsidence and varus-valgus rotation, independent of the system used. The precisions for out-of-plane migration were inferior for elementary geometrical shape RSA. Therefore, as a mechanism of failure, retroversion may be more difficult to detect early. This is to our knowledge the first study to compare different RSA systems with or without markers on the implant. Marker-based RSA has high precision in all planes, independent of the system used. Elementary geometrical shape RSA is inferior in out-of-plane migration. Copyright © 2014 Elsevier Ltd. All rights reserved.

  12. Implementation of additive technologies in elementary education

    Directory of Open Access Journals (Sweden)

    Milić Melita

    2017-01-01

    Full Text Available The use of additive manufacturing (AM in the wider sense at the level of elementary education is not sufficiently analysed in Republic of Croatia at the moment. Partially, CAD/CAM technologies requires far more specialized knowledge than what the Croatian curriculum provides. The application of different technological devices in the educational process, accelerates the teaching process, and makes it more interesting and more acceptable. The knowledge that pupil need to have at the end of schooling is rapidly changing. It is quite possible scenario that most of the knowledge gained during the elementary and secondary education will be obsolete before future student applies to the university. In order to achieve further progress, it is necessary to systematically explain all the possibilities of using these technologies from the elementary level. By developing different strategies, the young generation can focus on the knowledge they will need in their future jobs.

    The purpose of this qualitative case study was to gain a clear understanding of the manner in which fourth-grade students attending a Kansas elementary school learn when engaged in science activities grounded in H. Gardner's book, Frames of mind the theory of multiple intelligences (1983). The significance of this research lies in the discovery of the difference between teaching practice grounded in multiple intelligences versus that based upon traditional theory. Teacher self-perceptions with regard to the effectiveness of their instruction and student assessment within the classroom were also explored. The research evaluated the overall effectiveness of both traditional curriculum delivery and that rooted in the concept of multiple intelligences.

    2013-07-01

    A large body of literature illustrates that many elementary teachers are reluctant to teach science and confess a lack of confidence to teach it. Nevertheless, a review of the literature indicates a few cases of elementary teachers who do well in science and offers rare examples of enthusiast elementary teachers. The question then becomes how those cases came to be? The purpose of this study is to document two such cases of prospective elementary teachers, illustrate their unique characteristics and shed light on how those came to be. The study was designed upon a narrative inquiry approach focusing on the collection of personal stories. Multiple sources of data were used in order to examine the participants' science teaching orientations and the kinds of experiences that influenced their development: drawings, interviews, reflective assignments, and others. The analysis of the data was grounded within the Three-Dimensional Space Narrative Structure. The findings of the analysis illustrated that the participants perceived certain experiences they had during their university coursework as critical to shaping their orientations to science and science teaching: inquiry-based investigations, contemporary theoretical discussions, outdoors field study, friendly classroom environment and the characteristics of their instructors. These findings have implications for the design of teacher education courses that aim to engage prospective elementary teachers, especially females, in meaningful learning experiences and support them in developing science teaching orientations that are in line with reform recommendations.

  4. Chronic Teacher Turnover in Urban Elementary Schools

    Directory of Open Access Journals (Sweden)

    Kacey Guin

    2004-08-01

    Full Text Available This study examines the characteristics of elementary schools that experience chronic teacher turnover and the impacts of turnover on a school’s working climate and ability to effectively function. Based on evidence from staff climate surveys and case studies, it is clear that high turnover schools face significant organizational challenges. Schools with high teacher turnover rates have difficulty planning and implementing a coherent curriculum and sustaining positive working relationships among teachers. The reality of these organizational challenges is particularly alarming, given that high turnover schools are more likely to serve low-income and minority students. The negative relationship between teacher turnover and school functioning, and the fact that turbulent schools are disproportionately likely to serve lowincome and minority students have important implications for both district and school-level policies. Specifically: Teacher turnover rates are one indicator of school health, which school districts should consider when focusing on school improvements. Districts need to begin by developing the means to identify individual schools that experience high levels of teacher turnover. Current district policies in implementing professional development for teachers in low-performing schools are inefficient when teachers do not remain in the schools in which they are trained. In order for low-performing schools to improve, districts need to consider providing incentive programs so that high quality teachers apply for, and remain in, these schools. Future research is needed to address the causal link between turnover, organizational functioning and student outcomes. Additionally, there is a need for research examining district policies that may facilitate teacher turnover within a district, including how districts place and transfer teachers, as well as how teachers’ salaries are budgeted.

  5. Elementary science education: Dilemmas facing preservice teachers

    Science.gov (United States)

    Sullivan, Sherry Elaine

    Prospective teachers are involved in a process of induction into a culture of teaching that has rules, or codes of conduct for engaging in teaching practice. This same culture of teaching exists within a larger culture of schooling that also has values and norms for behaviors, that over time have become institutionalized. Teacher educators are faced with the challenging task of preparing preservice teachers to resolve dilemmas that arise from conflicts between the pressure to adopt traditional teaching practices of schooling, or to adopt inquiry-based teaching practices from their university methods classes. One task for researchers in teacher education is to define with greater precision what factors within the culture of schooling hinder or facilitate implementation of inquiry-based methods of science teaching in schools. That task is the focus of this study. A qualitative study was undertaken using a naturalistic research paradigm introduced by Lincoln and Guba in 1985. Participant observation, interviews, discourse analysis of videotapes of lessons from the methods classroom and written artifacts produced by prospective teachers during the semester formed the basis of a grounded theory based on inductive analysis and emergent design. Unstructured interviews were used to negotiate outcomes with participants. Brief case reports of key participants were also written. This study identified three factors that facilitated or hindered the prospective teachers in this research success in implementing inquiry-based science teaching in their field placement classrooms: (a) the culture of teaching/teacher role-socialization, (b) the culture of schooling and its resistance to change, and (c) the culture of teacher education, especially in regards to grades and academic standing. Some recommendations for overcoming these persistent obstacles to best practice in elementary science teaching include: (a) preparing prospective teachers to understand and cope with change

  10. Students' constructs of elementary school physical education.

    Science.gov (United States)

    Pissanos, B W; Allison, P C

    1993-12-01

    The constructivist educational orientation acknowledges that students construct their own learning as they experience and make meaning from their schooling. An elementary school physical education master teacher and 10 of her former students participated in a naturalistic study designed to answer two research questions: (a) How did 10 students at the time of their high school graduation construct the meaning of elementary school physical education? and (b) What factors associated with their elementary school physical education experiences influenced the ways they constructed meaning? Participants were asked to reminisce in a semistructured, open-ended interview format specifically designed to enhance the recall of their physical education experiences during the 7-year, K-6 time frame. Data were inductively analyzed using the constant comparative analytic strategy. The meanings constructed by the students from their elementary school physical education experiences were defined by the teacher's value orientation and her invitational teaching style. Gender was the only factor evidenced in influencing the construction of meaning, with females recalling more variety and greater detail in the sport curricular area.

    Nishimura, Takuma; Sakurai, Shigeo

    2013-02-01

    This study examined changes in academic motivation among elementary and junior high school students. Based on self-determination theory (Ryan & Deci, 2000a), we focused on changes in autonomous and controlled motivation. In Study 1, we examined inter-individual changes in academic motivation among 5th to 9th grade students (N = 1 572) through a cross-sectional study. In Study 2, we examined intra-individual changes in academic motivation among students (N = 128) who were in transition from elementary to junior high school through a longitudinal study. All participants completed the Academic Motivation Scale (Nishimura, Kawamura, & Sakurai, 2011) that measured autonomous and controlled motivation. The results revealed that autonomous motivation decreased in the students from elementary to junior high school, while controlled motivation increased during the same period. This is a unique finding because a prior study conducted in a Western culture suggested that both motivations decrease gradually in school.

    Zhao, Quanyu; Yu, Shuiyan; Shi, Jiping

    2013-06-01

    Elementary mode analysis is the widely applied tool in metabolic pathway analysis. Studies based on elementary mode analysis (EMA) were performed for both metabolic network and signal transduction network. Its analytical objective is from cell to bioreactor, and even ecological system. EMA is available to describe biological behaviors by steady state and dynamic models. Not only microorganism metabolism but also human health could be evaluated by EMA. The algorithms and software for calculating elementary mode (EM) were analyzed. The applications of EMA are reviewed such as special metabolic pathway and robustness of metabolic network, metabolic flux decomposition, metabolic flux analysis at steady state, dynamic model and bioprocess simulation, network structure and regulation, strain design and signal transduction network. Solving combinatorial explosion, exploring the relations between EM and metabolic regulation, and improving the algorithm efficiency of strain design are important issues of EMA in future.

    2014-12-01

    Full Text Available The following academic article is based on a PhD thesis that is currently being completed, titled Education and Qualifications of Elementary School Teachers in the U.S. State of Kansas and Slovenia for teaching in classes with immigrant children. The research study titled Integrating Multicultural Subject Matters into Teaching Strategies of Elementary School Teachers (The U.S. State of Kansas, conducted in 2007 based on a sample of 89 elementary school teachers in the U.S. State of Kansas, represents one aspect of assessing the adequacy of undergraduate education regarding multicultural subject matters for elementary school teachers in Slovenia and the U.S. (State of Kansas as well as the qualifications of elementary school teachers of both countries for working with immigrant children. Despite the long-standing tradition of multicultural education in western countries, the research results for Kansas elementary school teachers showed a presence of significant discrepancies between the actual and optimal integration of multicultural subject matters. These results indicate that future undergraduate study programs will have to invest more time in developing multicultural skills and providing practical experiences for working in a diverse environment.

  12. A Case Study Exploring the Identity of an In-Service Elementary Science Teacher: a Language Teacher First

    Science.gov (United States)

    Marco-Bujosa, Lisa; Levy, Abigail Jurist; McNeill, Katherine

    2018-01-01

    Teachers are central to providing high-quality science learning experiences called for in recent reform efforts, as their understanding of science impacts both what they teach and how they teach it. Yet, most elementary teachers do not enter the profession with a particular interest in science or expertise in science teaching. Research also indicates elementary schools present unique barriers that may inhibit science teaching. This case study utilizes the framework of identity to explore how one elementary classroom teacher's understandings of herself as a science specialist were shaped by the bilingual elementary school context as she planned for and provided reform-based science instruction. Utilizing Gee's (2000) sociocultural framework, identity was defined as consisting of four interrelated dimensions that served as analytic frames for examining how this teacher understood her new role through social positioning within her school. Findings describe the ways in which this teacher's identity as a science teacher was influenced by the school context. The case study reveals two important implications for teacher identity. First, collaboration for science teaching is essential for elementary teachers to change their practice. It can be challenging for teachers to form an identity as a science teacher in isolation. In addition, elementary teachers new to science teaching negotiate their emerging science practice with their prior experiences and the school context. For example, in the context of a bilingual school, this teacher adapted the reform-based science curriculum to better meet the unique linguistic needs of her students.

    School-based programs represent an ideal setting to enhance healthy eating, as most children attend school regularly and consume at least one meal and a number of snacks at school each day. However, current research reports that elementary school teachers often display low levels of nutritional knowledge, self-efficacy, and skills to effectively deliver nutrition education. The purpose of this review was to understand the availability and quality of resources that are accessible for elementary school teachers to use to support curriculum delivery or nutrition education programs. The review included 32 resources from 4 countries in the final analysis from 1989 to 2014. The 32 resources exhibited 8 dominant teaching strategies: curriculum approaches; cross-curricular approaches; parental involvement; experiential learning approaches; contingent reinforcement approaches; literary abstraction approaches; games-based approaches; and web-based approaches. The resources were accessible to elementary school teachers, with all the resources embedding curriculum approaches, and most of the resources embedding parental involvement strategies. Resources were less likely to embed cross-curricular and experiential learning approaches, as well as contingent reinforcement approaches, despite recent research suggesting that the most effective evidence-based strategies for improving healthy eating in elementary school children are cross-curricular and experiential learning approaches. © 2016, American School Health Association.

    Elementary education has theoretical underpinnings based on cognitive psychology. Ideas from cognitive psychologists such as James, Dewey, Piaget, and Vygotsky coalesce to form constructivism (Cooper, 1993; Yager, 2000; Yilmaz, 2011). Among others, the Montessori Method (1912/1964) is an exemplar of constructivism. Currently, public education in…

    Full Text Available Abstract Background Little is known about patterns in the transition from healthy weight to overweight or obesity during the elementary school years. This study examined whether there were distinct body mass index (BMI trajectory groups among elementary school children, and predictors of trajectory group membership. Methods This is a secondary analysis of 1651 elementary school children with complete biannual longitudinal data from kindergarten to the beginning of 5th grade. Heights and weights were measured by trained school nurses using standard procedures at the beginning and end of each school year for 11 consecutive assessments. Group-based trajectory clustering and multinomial logit modeling were conducted. Results When using BMIz score, six trajectory groups were identified revealing substantial consistency in BMIz score across time. When using a categorical variable separating overweight/obese children (BMI ≥ 85%ile from the rest, five developmental trajectories (persistently non-overweight/obese weight: 51.1 %; early-onset overweight/obese: 9.2 %; late-onset overweight/obese: 9.7 %; becoming healthy weight: 8.2 %; and chronically overweight/obese: 21.8 % were identified. When using a categorical variable separating obese children (BMI ≥ 95%ile from the rest, three trajectories (persistently non-obese: 74.1 %, becoming obese: 12.8 %; and chronically obese: 13.2 % were identified. For both cutoffs (≥ BMI percentile 85 % or 95 %, girls were more likely than boys to be classified in the persistently non-overweight and/or obese group (odds ratios (OR ranged from 0.53 to 0.67; and Hispanic children and non-Hispanic Black children were more likely to be chronically overweight and/or obese than non-Hispanic White children (OR ranged from 1.57 to 2.44. Hispanic children were also more likely to become obese (OR: 1.84 than non-Hispanic White children when ≥ BMI percentile 95 % was used. Conclusions Boys, Hispanic

  9. Perspectives on learning, learning to teach and teaching elementary science

    Science.gov (United States)

    Avraamidou, Lucy

    The framework that characterizes this work is that of elementary teachers' learning and development. Specifically, the ways in which prospective and beginning teachers' develop pedagogical content knowledge for teaching science in light of current recommendations for reform emphasizing teaching and learning science as inquiry are explored. Within this theme, the focus is on three core areas: (a) the use of technology tools (i.e., web-based portfolios) in support of learning to teach science at the elementary level; (b) beginning teachers' specialized knowledge for giving priority to evidence in science teaching; and (c) the applications of perspectives associated with elementary teachers' learning to teach science in Cyprus, where I was born and raised. The first manuscript describes a study aimed at exploring the influence of web-based portfolios and a specific task in support of learning to teach science within the context of a Professional Development School program. The task required prospective teachers to articulate their personal philosophies about teaching and learning science in the form of claims, evidence and justifications in a web-based forum. The findings of this qualitative case study revealed the participants' developing understandings about learning and teaching science, which included emphasizing a student-centered approach, connecting physical engagement of children with conceptual aspects of learning, becoming attentive to what teachers can do to support children's learning, and focusing on teaching science as inquiry. The way the task was organized and the fact that the web-based forum provided the ability to keep multiple versions of their philosophies gave prospective teachers the advantage of examining how their philosophies were changing over time, which supported a continuous engagement in metacognition, self-reflection and self-evaluation. The purpose of the study reported in the second manuscript was to examine the nature of a first

    Children do not eat enough servings of vegetables, underscoring the need for effective interventions encouraging this behavior. The purpose of this research was to measure the impact that daily exposure to branded vegetable characters has on vegetable selection among boys and girls in elementary schools. In a large urban school district, 10 elementary schools agreed to participate in the study. They were randomly assigned to a control condition or 1 of 3 treatment conditions: (1) a vinyl banner displaying vegetable characters that was fastened around the base of the salad bar; (2) short television segments with health education delivered by vegetable characters; or (3) a combination of the vinyl banner and television segments. We collected 22 206 student-day observations over a 6-week period by tallying the number of boys and girls taking vegetables from the school's salad bar. Results show that 90.5% (from 12.6% to 24.0%; P = .04) more students took vegetables from the salad bar when exposed to the vinyl banner only, and 239.2% (from 10.2% to 34.6%; P children's vegetable selection in the school cafeteria. Results from this study suggest potential opportunities for using branded media to encourage healthier choices for children. Copyright © 2016 by the American Academy of Pediatrics.

  12. Introducing Ergonomics in Two US Elementary Schools

    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 paper describes the process used to introduce ergonomics into two elementary schools in two different states by initiators with two different roles.

  13. Bubbles, shocks and elementary technical trading strategies

    In this paper we provide a unifying framework for a set of seemingly disparate models for bubbles, shocks and elementary technical trading strategies in financial markets. Markets operate by balancing intrinsic levels of risk and return. This seemingly simple observation is commonly over-looked by academics and practitioners alike. Our model shares its origins in statistical physics with others. However, under our approach, changes in market regime can be explicitly shown to represent a phase transition from random to deterministic behaviour in prices. This structure leads to an improved physical and econometric model. We develop models for bubbles, shocks and elementary technical trading strategies. The list of empirical applications is both interesting and topical and includes real-estate bubbles and the on-going Eurozone crisis. We close by comparing the results of our model with purely qualitative findings from the finance literature.

    Many science "museums” already offer fantastic programs for the general public, and even some aimed at elementary school kids. However, these venues are usually located in large cities and are only occasionally used as tools for enriching science education in public schools. Here we present preliminary work to establish exciting educational enrichment environments for public schools that do not easily have access to such facilities. This program is aimed at motivating children's interest in science beyond what they learn in the classroom setting. In this program, we use the experience and experiments/demonstrations developed at a large science museum (in this case, The St. Louis Science Center) and take them into a local elementary school. At the same time, students from the University of Missouri are getting trained on how to present these outreach materials and work with the local elementary schools. Our pilot study has started with implementation of presentations/demonstrations at Benton Elementary School within the Columbia Public School district, Missouri. The school has recently adopted a STEM (Science, Technology, Engineering, and Mathematics) centered learning system throughout all grade levels (K-5), and is therefore receptive to this effort. We have implemented a program in which we have given a series of scientific demonstrations at each grade level's lunch hour. Further enrichment ideas and plans include: addition demonstrations, hands-on experiments, and question and answer sessions. However, the application of these events would be to compliment the curriculum for the appropriate grade level at that time. The focus of this project is to develop public communications which links science museums, college students and local public schools with an emphasis on encouraging college science majors to share their knowledge and to strengthen their ability to work in a public environment.

  19. Implementing Elementary School Next Generation Science Standards

    Kennedy, Katheryn B.

    Implementation of the Next Generation Science Standards requires developing elementary teacher content and pedagogical content knowledge of science and engineering concepts. Teacher preparation for this undertaking appears inadequate with little known about how in-service Mid-Atlantic urban elementary science teachers approach this task. The purpose of this basic qualitative interview study was to explore the research questions related to perceived learning needs of 8 elementary science teachers and 5 of their administrators serving as instructional leaders. Strategies needed for professional growth to support learning and barriers that hamper it at both building and district levels were included. These questions were considered through the lens of Schon's reflective learning and Weick's sensemaking theories. Analysis with provisional and open coding strategies identified informal and formal supports and barriers to teachers' learning. Results indicated that informal supports, primarily internet usage, emerged as most valuable to the teachers' learning. Formal structures, including professional learning communities and grade level meetings, arose as both supportive and restrictive at the building and district levels. Existing formal supports emerged as the least useful because of the dominance of other priorities competing for time and resources. Addressing weaknesses within formal supports through more effective planning in professional development can promote positive change. Improvement to professional development approaches using the internet and increased hands on activities can be integrated into formal supports. Explicit attention to these strategies can strengthen teacher effectiveness bringing positive social change.

    This work is addressed to educators and geography, science, biology and physics teachers who deal with elementary, middle and high school education. It discusses the importance of adopting the anthropological perspective regarding issues that are considered within the astronomy area. It also presents practical proposals for those who intend to introduce cultural astronomy in elementary, middle and high school education - from the beginning of the 1st grade in Elementary school to the end of the 3rd grade in Secondary school, in formal as well as in informal education. This work is proposed within the context of the holistic and transdisciplinary environmental education. Our approach values above all the experience and aims at a humanistic education that includes epistemological and cultural diversities. The suggested practical proposals can be also beneficially used to address works that include contents related to Brazilian indigenous and Afro-descent cultures in the school curriculum, as the new law requires. The guidelines presented here were tested in real school situations.
