    Full Text Available This case study was based on a school where the Tier 1 Program of the Project P.A.T.H.S. was integrated into the formal curriculum. In this case study, an interview with the school principal, vice-principal, and social worker was conducted in order to understand their perceptions of administrative arrangements and issues in the school, implementation characteristics, program effectiveness, program success, and overall impression. Results showed that several positive school and classroom attributes were conducive to program success, including positive school culture and belief in students' potentials, an inviting school environment, an encouraging classroom environment, high involvement of school administrative personnel, and systematic program arrangement.

    Occupational therapists assess and adapt an environment to enhance clients' abilities to function. Therapists working in schools may assess several classroom environments in a week. Identifying relevant information in an efficient manner is essential yet presents a challenge for school therapists. In this study, ethnographic research methodology was used to analyze the plethora of data gained from observations in eight classrooms. Three major categories were identified to structure observations: activities, people, and communication. These categories were used to compile a Classroom Observation Guide that gives therapists relevant questions to ask in each category. Using the Classroom Observation Guide, occupational therapists can recommend classroom activities that suit a particular teacher's style. For example, working with a teacher who prefers structural activities with clear time and space boundaries for one specific purpose, a therapist might suggest organized sensorimotor games with a distinct purpose to be carried out for a given time period.

  6. Neuroscientists' classroom visits positively impact student attitudes.

    Directory of Open Access Journals (Sweden)

    Janet L Fitzakerley

    Full Text Available The primary recommendation of the 2010 President's Council of Advisors on Science and Technology report on K-12 education was to inspire more students so that they are motivated to study science. Scientists' visits to classrooms are intended to inspire learners and increase their interest in science, but verifications of this impact are largely qualitative. Our primary goal was to evaluate the impact of a longstanding Brain Awareness classroom visit program focused on increasing learners understanding of their own brains. Educational psychologists have established that neuroscience training sessions can improve academic performance and shift attitudes of students from a fixed mindset to a growth mindset. Our secondary goal was to determine whether short interactive Brain Awareness scientist-in-the-classroom sessions could similarly alter learners' perceptions of their own potential to learn. Teacher and student surveys were administered in 4(th-6(th grade classrooms throughout Minnesota either before or after one-hour Brain Awareness sessions that engaged students in activities related to brain function. Teachers rated the Brain Awareness program as very valuable and said that the visits stimulated students' interest in the brain and in science. Student surveys probed general attitudes towards science and their knowledge of neuroscience concepts (particularly the ability of the brain to change. Significant favorable improvements were found on 10 of 18 survey statements. Factor analyses of 4805 responses demonstrated that Brain Awareness presentations increased positive attitudes toward science and improved agreement with statements related to growth mindset. Overall effect sizes were small, consistent with the short length of the presentations. Thus, the impact of Brain Awareness presentations was positive and proportional to the efforts expended, demonstrating that short, scientist-in-the-classroom visits can make a positive contribution to

  7. Classroom acoustics and intervention strategies to enhance the learning environment

    Science.gov (United States)

    Savage, Christal

    The classroom environment can be an acoustically difficult atmosphere for students to learn effectively, sometimes due in part to poor acoustical properties. Noise and reverberation have a substantial influence on room acoustics and subsequently intelligibility of speech. The American Speech-Language-Hearing Association (ASHA, 1995) developed minimal standards for noise and reverberation in a classroom for the purpose of providing an adequate listening environment. A lack of adherence to these standards may have undesirable consequences, which may lead to poor academic performance. The purpose of this capstone project is to develop a protocol to measure the acoustical properties of reverberation time and noise levels in elementary classrooms and present the educators with strategies to improve the learning environment. Noise level and reverberation will be measured and recorded in seven, unoccupied third grade classrooms in Lincoln Parish in North Louisiana. The recordings will occur at six specific distances in the classroom to simulate teacher and student positions. The recordings will be compared to the American Speech-Language-Hearing Association standards for noise and reverberation. If discrepancies are observed, the primary investigator will serve as an auditory consultant for the school and educators to recommend remediation and intervention strategies to improve these acoustical properties. The hypothesis of the study is that the classroom acoustical properties of noise and reverberation will exceed the American Speech-Language-Hearing Association standards; therefore, the auditory consultant will provide strategies to improve those acoustical properties.

    1990-01-01

    Development of an innovative, integrated, automated system (Global Positioning Site Environment Evaluator - GPSEETM) for surveying contaminated waste sites is described. This system makes novel use of the Global Positioning System (GPS) satellite constellation for establishing specific locations and current times for surveying radioactive, hazardous, or mixed-waste sites. GPSEE may also be used for waste site contamination surveys after remediation activities to ensure environmental remediation is complete. A base station is established for collecting and recording data and directing field operations for field stations which may be located many miles from the base station. The field operators collect site surveying and contamination data utilizing a variety of chemical and radiological sensors. A major goal for the data collection process is to collect all data utilizing in situ sensors, thereby minimizing the need for collecting soil and water samples. Site contamination data is transmitted electronically to the base station for recording and processing. The GPSEE system is being developed for use at DOE/DOD and a variety of industrial facilities. 3 figs

    2018-04-16

    Occupational therapists offer a unique perspective regarding the contribution of the environment to occupational performance. Therefore, a scale that measures the unique characteristics of the primary school classroom environment where children complete their daily schoolwork occupations is needed. The aim of this study was to develop and psychometrically evaluate a new teacher-report questionnaire that measures a number of environmental characteristics of primary school classrooms. Participants (N = 117) completed the Classroom Environment Questionnaire (CEQ), which utilises a 4-point Likert scale where teachers rate 51 environmental characteristics of their classroom. Teachers also rate the extent to which they believe the physical, social, temporal, institutional and cultural classroom environmental domains contribute to students' schoolwork performance using a 10-point scale. The structural validity of the CEQ was examined using principal component analysis (PCA). Inter-item correlations were examined using Pearson r correlations, while the internal consistency of the CEQ was assessed using Cronbach's alpha. PCA revealed the CEQ to be multidimensional, with 31 items loading onto nine viable factors, representing the unique nature of classroom environments. Based on the PCA results, 20 items were removed from the CEQ. Cronbach's alpha and correlation analysis indicated that most CEQ subsections had acceptable internal consistency (alpha range 0.70-0.82), with four subsections demonstrating a lower level of internal consistency (alpha range 0.55-0.69). Preliminary structural validity and internal consistency analysis findings confirm that the CEQ has potential to be a useful scale for professionals wishing to examine the unique characteristics of primary school classrooms that influence the occupational performance of students. Ongoing analyses will be undertaken to further explore the CEQ's validity and reliability. © 2018 Occupational Therapy Australia.

  19. An Evaluation of the Measurement of Perceived Classroom Assessment Environment

    Directory of Open Access Journals (Sweden)

    Hussain Alkharusi

    2015-07-01

    Full Text Available A classroom assessment environment is a classroom context experienced by students as the teacher determines assessment purposes, develops assessment tasks, defines assessment criteria and standards, provides feedback, and monitors outcomes (Brookhart, 1997. It is usually a group experience varying from class to class dependent upon the teacher’s assessment practices (Brookhart, 2004. As such, the measurement of class-level perception of the assessment environment should deserve recognition and investigation. This study aimed at evaluating the measurement of the perceived classroom assessment environment by comparing the psychometric properties of the scale at the student level and class level. Using a multi-stage random sampling process, data were collected from 4088 students nested within 236 classes of the second cycle of the basic education in the Sultanate of Oman. Students responded to the 18-items of Alkharusi's (2011 Perceived Classroom Assessment Environment Scale. Results of the principal axis factoring yielded two factors, learning-oriented and performance-oriented assessment environment, at both levels. However, the two factors explained about 38% of the variance at the class level compared to about 20% of the variance at the student level. Reliability coefficients in terms of Cronbach alpha ranged between .79 and .83 at the class level compared to .65 and .67 at the student level

    2014-06-01

    This study details the initial development of the Responsive Environmental Assessment for Classroom Teachers (REACT). REACT was developed as a questionnaire to evaluate student perceptions of the classroom teaching environment. Researchers engaged in an iterative process to develop, field test, and analyze student responses on 100 rating-scale items. Participants included 1,465 middle school students across 48 classrooms in the Midwest. Item analysis, including exploratory and confirmatory factor analysis, was used to refine a 27-item scale with a second-order factor structure. Results support the interpretation of a single general dimension of the Classroom Teaching Environment with 6 subscale dimensions: Positive Reinforcement, Instructional Presentation, Goal Setting, Differentiated Instruction, Formative Feedback, and Instructional Enjoyment. Applications of REACT in research and practice are discussed along with implications for future research and the development of classroom environment measures.

    2013-11-01

    In nursing education, the inclusion of pedagogical tools is necessary to transform Millennial classrooms. One such pedagogical tool currently offered is classroom response systems (CRS). The purpose of this study was to evaluate the effectiveness of CRS as a pedagogical tool in improving nursing students' examination performance within an active learning environment. A pretest-posttest design was used to determine whether there was a relationship between the use of CRS (independent variable) and nursing students' examination performance in a first-year Professional Practice course (dependent variable). Paired t tests revealed no greater improvement in posttest scores. Therefore, the use of CRS technology was not effective in increasing nursing students' examination scores in the Professional Practice course. Additional research is needed to provide adequate understanding of the effectiveness of CRS within the nursing education classroom. Copyright 2013, SLACK Incorporated.

  12. Is there a correlation between students' perceptions of their middle school science classroom learning environment and their classroom grades?

    Science.gov (United States)

    Snyder, Wayne

    The purpose of this study was to determine if the marking period grades of middle school science students are correlated with their perception of the classroom learning environment, and if so could such an indicator be used in feedback loops for ongoing classroom learning environment evaluation and evolution. The study examined 24 classrooms in three districts representing several different types of districts and a diverse student population. The independent variable was the students' perceptions of their classroom learning environment (CLE). This variable was represented by their responses on the WIHIC (What Is Happening In This Class) questionnaire. The dependent variable was the students' marking period grades. Background data about the students was included, and for further elaboration and clarification, qualitative data was collected through student and teacher interviews. Middle school science students in this study perceived as most positive those domains over which they have more locus of control. Perceptions showed some variance by gender, ethnicity, teacher/district, and socio-economic status when viewing the absolute values of the domain variables. The patterns of the results show consistency between groups. Direct correlation between questionnaire responses and student grades was not found to be significant except for a small significance with "Task Orientation". This unexpected lack of correlation may be explained by inconsistencies between grading schemes, inadequacies of the indicator instrument, and/or by the one-time administration of the variables. Analysis of the qualitative and quantitative data led to the conclusion that this instrument is picking up information, but that revisions in both the variables and in the process are needed. Grading schemes need to be decomposed, the instrument needs to be revised, and the process needs to be implemented as a series of regular feed-back loops.

    2017-01-01

    Full Text Available Positive psychology has multiple applications. This article is focused on formal education, from the ages of 3 to 18 years. The development of well-being should be one of the aims of education, which would affect teachers, students, families and by extension society at large. This has been a clear aim for emotional education (Bisquerra, 2000, 2009, from the outset. With the emergence of positive psychology, there was a renewed effort in this direction, as a means of providing a better foundation. GROP (Grup de Recerca en Orientación Psicopedagógica [Research in Psychopedagogical Education Group] at the University of Barcelona is conducting research on this subject. The Happy Classrooms (“Aulas felices” program developed by the SATI team is the first program in Spanish aimed at working on positive education. It is designed for children and youths in pre-school, primary and secondary education. The program focuses its applications on character strengths and mindfulness. It is freely available for access and distribution. This article argues for the importance of enhancing well-being in education. Practical activities and intervention strategies are presented, with special reference to the importance of teacher training.

    2011-11-01

    Full Text Available This paper deploys notions of emergence, connections, and designs for learning to conceptualize high school students’ interactions when using online social media as a learning environment. It makes links to chaos and complexity theories and to fractal patterns as it reports on a part of the first author’s action research study, conducted while she was a teacher working in an Australian public high school and completing her PhD. The study investigates the use of a Ning online social network as a learning environment shared by seven classes, and it examines students’ reactions and online activity while using a range of social media and Web 2.0 tools.The authors use Graham Nuthall’s (2007 “lens on learning” to explore the social processes and culture of this shared online classroom. The paper uses his extensive body of research and analyses of classroom learning processes to conceptualize and analyze data throughout the action research cycle. It discusses the pedagogical implications that arise from the use of social media and, in so doing, challenges traditional models of teaching and learning.

  20. Second language writing anxiety, computer anxiety, and performance in a classroom versus a web-based environment

    Directory of Open Access Journals (Sweden)

    Effie Dracopoulos

    2011-04-01

    Full Text Available This study examined the impact of writing anxiety and computer anxiety on language learning for 45 ESL adult learners enrolled in an English grammar and writing course. Two sections of the course were offered in a traditional classroom setting whereas two others were given in a hybrid form that involved distance learning. Contrary to previous research, writing anxiety showed no correlation with learning performance, whereas computer anxiety only yielded a positive correlation with performance in the case of classroom learners. There were no significant differences across learning environments on any measures. These observations are discussed in light of the role computer technologies now play in our society as well as the merging of socio-demographic profiles between classroom and distance learners. Our data suggest that comparisons of profiles between classroom and distance learners may not be an issue worth investigating anymore in language studies, at least in developed countries.

  1. Linking Classroom Environment with At-Risk Engagement in Science: A Mixed Method Approach

    Science.gov (United States)

    Collins, Stephen Craig

    This explanatory sequential mixed-method study analyzed how the teacher created learning environment links to student engagement for students at-risk across five science classroom settings. The learning environment includes instructional strategies, differentiated instruction, positive learning environment, and an academically challenging environment. Quantitative and qualitative data were gathered in the form of self-reporting surveys and a follow-up interview. The researcher aimed to use the qualitative results to explain the quantitative data. The general research question was "What are the factors of the teacher-created learning environment that were best suited to maximize engagement of students at-risk?" Specifically explaining, (1) How do the measured level of teacher created learning environment link to the engagement level of students at-risk in science class? and (2) What relationship exists between the student perception of the science classroom environment and the level of behavioral, cognitive, emotional, and social engagement for students at-risk in science class? This study took place within a large school system with more than 20 high schools, most having 2000-3000 students. Participating students were sent to a panel hearing that determined them unfit for the regular educational setting, and were given the option of attending one of the two alternative schools within the county. Students in this alternative school were considered at-risk due to the fact that 98% received free and reduced lunch, 97% were minority population, and all have been suspended from the regular educational setting. Pairwise comparisons of the SPS questions between teachers using t-test from 107 students at-risk and 40 interviews suggest that each category of the learning environment affects the level of behavioral, cognitive, emotional, and social engagement in science class for students at-risk in an alternative school setting. Teachers with higher student perceptions of

    Full Text Available Triadic dialogue, the Initiation, Response, Evaluation sequence typical of teacher /student interactions in classrooms, has long been identified as a barrier to students’ access to learning, including science learning. A large body of research on the subject has over the years led to projects and policies aimed at increasing opportunities for students to learn through interactive dialogue in classrooms. However, the triadic dialogue pattern continues to dominate, even when teachers intend changing this. Prior quantitative research on the subject has focused on identifying independent variables such as style of teacher questioning that have an impact, while qualitative researchers have worked to interpret the use of dialogue within the whole context of work in the classroom. A recent paper offers an alternative way to view the triadic dialogue pattern and its origin; the triadic dialogue pattern is an irreducible social phenomenon that arises in a particular situation regardless of the identity of the players who inhabit the roles in the turn-taking sequence (Roth & Gardner, 2012. According to this perspective, alternative patterns of dialogue would exist which are alternative irreducible social phenomena that arise in association with different situations. The aim of this paper is to examine as precisely as possible, the characteristics of dialogue patterns in a seventh-eighth grade classroom during science inquiry, and the precise situations from which these dialogue patterns emerge, regardless of the staffing (teacher or students in the turn-taking sequence. Three different patterns were identified each predominating in a particular situation. This fine-grained analysis could offer valuable insights into ways to support teachers working to alter the kinds of dialogue patterns that arise in their classrooms.

    Corrias, Alberto; Cho Hong, James Goh

    2015-01-01

    The design and implementation of a learning environment that leverages on the use of various technologies is presented. The context is an undergraduate core engineering course within the biomedical engineering curriculum. The topic of the course is data analysis in biomedical engineering problems. One of the key ideas of this study is to confine the most mathematical and statistical aspects of data analysis in prerecorded video lectures. Students are asked to watch the video lectures before coming to class. Since the classroom session does not need to cover the mathematical theory, the time is spent on a selected real world scenario in the field of biomedical engineering that exposes students to an actual application of the theory. The weekly cycle is concluded with a hands-on tutorial session in the computer rooms. A potential problem would arise in such learning environment if the students do not follow the recommendation of watching the video lecture before coming to class. In an attempt to limit these occurrences, two key instruments were put in place: a set of online self-assessment questions that students are asked to take before the classroom session and a simple rewards system during the classroom session. Thanks to modern learning analytics tools, we were able to show that, on average, 57.9% of students followed the recommendation of watching the video lecture before class. The efficacy of the learning environment was assessed through various means. A survey was conducted among the students and the gathered data support the view that the learning environment was well received by the students. Attempts were made to quantify the impacts on learning of the proposed measures by taking into account the results of selected questions of the final examination of the course. Although the presence of confounding factors demands caution in the interpretation, these data seem to indicate a possible positive effect of the use of video lectures in this technologically

    2013-05-01

    Children with type 1 diabetes (T1D) spend 4-7 h/day in school with very little supervision of their diabetes management. Therefore, families have become more dependent on technology, such as use of real-time continuous glucose monitoring (RT-CGM), to provide increased supervision of their diabetes management. We sought to assess the impact of RT-CGM use in the classroom/school environment. Children with T1D using RT-CGM, their parents, and teachers completed a questionnaire about RT-CGM in the classroom/school environment. The RT-CGM was tolerated well in the classroom/school environment. Seventy percent of parents, 75% of students, and 51% of teachers found RT-CGM useful in the classroom/school environment. The students found the device to be more disruptive than did their parents and teachers. However, all three groups agreed that RT-CGM increased their comfort with diabetes management at school. Our study suggests that RT-CGM is useful and not disruptive in the classroom/school environment. The development of education materials for teachers could further increase its acceptance in the classroom/school environment.

    Day, Stephanie L; Connor, Carol McDonald; McClelland, Megan M

    2015-10-01

    Classroom learning environments are an important source of influence on children's development, particularly with regard to literacy achievement and behavioral regulation, both of which require the coordination of task inhibition, attention, and working memory. Classroom observations were conducted in 18 schools and 51 first grade classrooms for 500 children. The non-instructional activities were recorded for each student in the classroom. Hierarchical linear modeling revealed that children with weaker fall behavioral regulation were more likely to attend classrooms where more time was spent in disruptions and wasted instructional time over the course of the school year, such as waiting for the teacher to gather materials before beginning instruction. For literacy outcomes, children who were in classrooms where more time in disruptions, transitions, and waiting was observed showed weaker literacy skill gains in the spring compared to children in classrooms with lesser amounts of such unproductive non-instructional time and this effect was generally greater for students with initial weaker skills. These results also reveal that the classroom environment and the incoming characteristics of the students themselves influence students' development of behavioral regulation and literacy.

    Prior research has indicated that highly motivated students perform better and that learning increases in innovative, reformed classrooms, but untangling the student effects from the instructor effects is essential to understanding how to best support student learning. Using a hierarchical linear model, we examine these effects separately and jointly. We use data from nearly 2,000 undergraduate students surveyed by the NSF-funded GARNET (Geoscience Affective Research NETwork) project in 65 different introductory geology classes at research universities, public masters-granting universities, liberal arts colleges and community colleges across the US. Student level effects were measured as increases in expectancy and self-regulation using the Motivated Strategies for Learning Questionnaire (MSLQ; Pintrich et al., 1991). Instructor level effects were measured using the Reformed Teaching Observation Protocol, (RTOP; Sawada et al., 2000), with higher RTOP scores indicating a more reformed, student-centered classroom environment. Learning was measured by learning gains on a Geology Concept Inventory (GCI; Libarkin and Anderson, 2005) and normalized final course grade. The hierarchical linear model yielded significant results at several levels. At the student level, increases in expectancy and self-regulation are significantly and positively related to higher grades regardless of instructor; the higher the increase, the higher the grade. At the instructor level, RTOP scores are positively related to normalized average GCI learning gains. The higher the RTOP score, the higher the average class GCI learning gains. Across both levels, average class GCI learning gains are significantly and positively related to student grades; the higher the GCI learning gain, the higher the grade. Further, the RTOP scores are significantly and negatively related to the relationship between expectancy and course grade. The lower the RTOP score, the higher the correlation between change in

    2015-01-01

    Character strengths have been found to be substantially related to children's and adolescents' well-being. Initial evidence suggests that they also matter for school success (e.g., Weber and Ruch, 2012). The present set of two studies aimed at replicating and extending these findings in two different age groups, primary school students (N = 179; mean age = 11.6 years) and secondary school students (N = 199; mean age = 14.4 years). The students completed the VIA-Youth (Values in Action Inventory of Strengths for Youth), a self-report measure of the 24 character strengths in the VIA classification. Their teachers rated the students' positive behavior in the classroom. Additionally, school achievement was assessed: For the primary school students (Study 1), teachers rated the students' overall school achievement and for the secondary school students (Study 2), we used their grades as a measure of school achievement. We found that several character strengths were associated with both positive classroom behavior and school achievement. Across both samples, school achievement was correlated with love of learning, perseverance, zest, gratitude, hope, and perspective. The strongest correlations with positive classroom behavior were found for perseverance, self-regulation, prudence, social intelligence, and hope. For both samples, there were indirect effects of some of the character strengths on school achievement through teacher-rated positive classroom behavior. The converging findings from the two samples support the notion that character strengths contribute to positive classroom behavior, which in turn enhances school achievement. Results are discussed in terms of their implications for future research and for school interventions based on character strengths.

    The purpose of this experiment was to explore whether listening positions (close or distant location from the sound source) in the classroom, and classroom reverberation, influence students’ score on a test for second-language (L2) listening comprehension (i.e., comprehension of English in Swedish speaking participants). The listening comprehension test administered was part of a standardized national test of English used in the Swedish school system. A total of 125 high school pupils, 15 years old, participated. Listening position was manipulated within subjects, classroom reverberation between subjects. The results showed that L2 listening comprehension decreased as distance from the sound source increased. The effect of reverberation was qualified by the participants’ baseline L2 proficiency. A shorter reverberation was beneficial to participants with high L2 proficiency, while the opposite pattern was found among the participants with low L2 proficiency. The results indicate that listening comprehension scores—and hence students’ grade in English—may depend on students’ classroom listening position. PMID:27304980

    Recent data suggest that severe stress during the adolescent period is becoming a problem of epidemic proportions. Elicitation of the relaxation response (RR) has been shown to be effective in treating anxiety, reducing stress, and increasing positive health behaviors. The research team's objective was to assess the impact of an RR-based curriculum, led by teachers, on the psychological status and health management behaviors of high-school students and to determine whether a train-the-trainer model would be feasible in a high-school setting. The research team designed a pilot study. The setting was a Horace Mann charter school within Boston's public school system. Participants were teachers and students at the charter school. The team taught teachers a curriculum that included (1) relaxation strategies, such as breathing and imagery; (2) psychoeducation regarding mind-body pathways; and (3) positive psychology. Teachers implemented this curriculum with students. The research team assessed changes in student outcomes (eg, stress, anxiety, and stress management behaviors) using preintervention/postintervention surveys, including the Perceived Stress Scale (PSS), the State-Trait Anxiety Inventory-Form Y (STAI-Y), the stress management subscale of the Health-promoting Lifestyle Profile II (HPLP-II), the Rosenberg Self-Esteem Scale (RSES), the Locus of Control (LOC) questionnaire, and the Life Orientation Test-Revised (LOTR). Classroom observations using the Classroom Assessment Scoring System (CLASS)-Secondary were also completed to assess changes in classroom environment.

    Harty, Harold; Hassan, Hassan A.

    An examination was made concerning the relationships between Sudanese secondary science teachers' pupil control ideology and their students' perceptions/observations of the psychosocial environment of their science classrooms. One hundred secondary science teachers were classified as possessing humanistic (N = 20) or custodial (N = 20) control ideologies. A class (N = 40) of students was randomly selected for every teacher in both groups. The findings revealed that no significant relationships existed between the control ideologies of the teachers and their students' perceptions/observations of the classroom environment. Custodialism in control ideology was significantly related to the classroom environment psychosocial aspect of low support. Discussion and implications of the findings have been approached from both Sudanese and American perspectives.

  20. Students' Positioning in the Classroom: a Study of Teacher-Student Interactions in a Socioscientific Issue Context

    Science.gov (United States)

    Bossér, Ulrika; Lindahl, Mats

    2017-07-01

    The integration of socioscientific issues (SSI) in science education calls for emphasizing dialogic classroom practices that include students' views together with multiple sources of knowledge and diverse perspectives on the issues. Such classroom practices aim to empower students to participate in decision-making on SSI. This can be accomplished by enhancing their independence as learners and positioning them as legitimate participants in societal discussions. However, this is a complex task for science teachers. In this study, we introduce positioning theory as a lens to analyse classroom discourse on SSI in order to enhance our knowledge of the manners by which teachers' interactions with students make available or promote different positions for the students, that is, different parts for the students to play as participants, when dealing with SSI in the classroom. Transcripts of interactions between one teacher and six student groups, recorded during two lessons, were analysed with respect to the positioning of the students as participants in the classroom, and in relation to the SSI under consideration. The results show that the teacher-student interactions made available contrasting student positions. The students were positioned by the teacher or positioned themselves as independent learners or as dependent on the teacher. Furthermore, the students were positioned as affected by the issue but as spectators to public negotiations of the issue. Knowledge about the manner in which teacher-student interactions can function to position students seems important for dialogic classroom practices and the promotion of student positions that sustain the pursuit of intended educational outcomes.

    Full Text Available This study aimed to measure conceptual change on stoichiometry using mental models and ill-structured problems in flipped classroom environment. This study examined the level of conceptual understanding of students on stoichiometry before and after exposure to flipped and traditional lecture method. It also covered the type of conceptual change, and students’ description in flipped classroom environment. Qualitative and quantitative research methods were used in the study. Respondents were two sections of third year Bachelor of Secondary Education, Biological Science. Frequency, percentage, ranking, mean, standard deviation, Hake factor test, and t-test were the statistical tools applied to answer specific questions. Results showed profound increase towards conceptual change representing a shift from intuitive understanding to correct incomplete understanding level. Thus, change for the better, in theoretical type was determined from pretest to posttest of students exposed to flipped and traditional instruction. Results also indicated that there is no significant difference on students’ conceptual change on stoichiometry exposed to flipped and traditional lecture method. Furthermore, students strongly agreed that flipped classroom instruction helped them develop positive attitude towards chemistry and appropriate for learning college chemistry.

  5. Ironless Inductive Position Sensor for Harsh Magnetic Environments

    CERN Document Server

    Danisi, Alessandro; Masi, Alessandro

    Linear Variable Differential Transformers (LVDTs) are widely used for high-precision and high-accuracy linear position sensing in harsh environments, such as the LHC collimators at CERN. These sensors guarantee theoretically infinite resolution and long lifetimes thanks to contactless sensing. Furthermore, they offer very good robustness and ruggedness, as well as micrometer uncertainty over a range of centimeters when proper conditioning techniques are used (such as the three-parameter Sine-Fit algorithm). They can also be suitable for radioactive environments. Nevertheless, an external DC/slowly-varying magnetic field can seriously affect the LVDT reading, leading to position drifts of hundreds of micrometers, often unacceptable in high-accuracy applications. The effect is due to the presence of non-linear ferromagnetic materials in the sensor’s structure. A detailed Finite Element model of an LVDT is first proposed in order to study and characterize the phenomenon. The model itself becomes a powerful de...

    2015-09-01

    Full Text Available This essay presents metacognition as a tool to promote a classroom environment inclusive for students with disabilities. It aims at promoting reflection on the methodology to address diversity within the classroom, considering the population with disabilities as one of the major groups to bear in mind. Within the conceptual approach, inclusive education is seen as the way to address diversity in the Costa Rican education system, where education is considered a fundamental human right. The Ministry of Public Education of Costa Rica is moving from a rehabilitative approach to an inclusive education approach. Metacognition is a way to raise awareness on the pedagogical mediation within the classroom environment. This paper includes results from a series of descriptive and qualitative studies conducted at Universidad Nacional, Costa Rica, which demonstrate that many of the difficulties presented in the student population are due to methodological aspects and an inadequate delivery of the contents by the teachers. The methodology used helps us to understand the ways in which students perform the cognitive processes through metacognitive strategies. It is concluded that the teaching strategies proposed to meet the educational needs comprehensively is fundamental for achieving inclusive educational processes.

    Synthetic quilt use has been associated with increased childhood wheeze in previous studies. Our aim was to examine whether the adverse effect of synthetic quilt use on frequent wheeze differed by usual sleep position. A population-based cross-sectional study of 6378 (92% of those eligible) 7-year-olds in Tasmania, Australia, was conducted in 1995. Exercise-challenge lung function was obtained on a subset of 414 children from randomly selected schools. Child bedding including pillow and overbedding composition and usual sleep position by parental questionnaire. Frequent wheeze (>12 wheeze episodes over the past year), using the International Study of Asthma and Allergies in Childhood parental questionnaire, and baseline and postexercise forced expiratory volume in 1 second lung-function measures. Frequent wheeze (n = 117) was positively associated with synthetic quilts, synthetic pillows, electric blankets, and sleeping in a bottom bunk bed but did not vary by sleep position. In a nested case-control analysis, the association between synthetic quilt use and frequent wheeze differed by sleep position. Among children who slept supine, synthetic (versus feather) quilt use was associated with frequent wheeze (adjusted odds ratio: 2.37 [1.08, 5.23]). However, among nonsupine sleepers, overlying synthetic quilt use was not associated with frequent wheeze (adjusted odds ratio: 1.06 [0.60, 1.88]). This difference in quilt effect by sleep position was highly significant. Similarly, synthetic quilt use was associated with lower postexercise forced expiratory volume in 1 second measures among supine but not nonsupine sleeping children. An increasing focus on the bedding environment immediately adjacent to the nose and mouth is required for respiratory disorders provoked by bedding, such as child asthma characterized by frequent wheeze.

    A year-long field study of the thermal environment in university classrooms was conducted from March 2005 to May 2006 in Chongqing, China. This paper presents the occupants' thermal sensation votes and discusses the occupants' adaptive response and perception of the thermal environment in a naturally conditioned space. Comparisons between the Actual Mean Vote (AMV) and Predicted Mean Vote (PMV) have been made as well as between the Actual Percentage of Dissatisfied (APD) and Predicted Percentage of Dissatisfied (PPD). The adaptive thermal comfort zone for the naturally conditioned space for Chongqing, which has hot summer and cold winter climatic characteristics, has been proposed based on the field study results. The Chongqing adaptive comfort range is broader than that of the ASHRAE Standard 55-2004 in general, but in the extreme cold and hot months, it is narrower. The thermal conditions in classrooms in Chongqing in summer and winter are severe. Behavioural adaptation such as changing clothing, adjusting indoor air velocity, taking hot/cold drinks, etc., as well as psychological adaptation, has played a role in adapting to the thermal environment.

    The Facultad de Medicina of the Universidad de La Sabana routinely uses lectures as the major educational strategy in clinical areas. Since 2012, a curriculum in context and a flipped classroom were introduced in the surgery course. To compare the impact of lectures versus the flipped classroom model in the learning environment in surgery. The Dundee Ready Education Environment Measure (DREEM) questionnaire was administered to four cohorts of students. The five domains and the overall scores for both strategies were analyzed, and ANOVA was used to determine the differences among the domains (pflipped classroom, which suggests that this environment had a higher level of excellence. The ANOVA for each domain and the overall scores showed no differences with a flipped classroom. However, significant differences were identified in all domains and the overall scores with lectures (p0.90) for all measurements in both environments, and there was consistency across all cohorts. The flipped classroom strategy showed a higher score than the lecture-based approach according to the DREEM questionnaire. Identifying factors with a negative score is crucial to improving the learning environment. It is necessary to conduct further measurements over time to ensure the quality and success of the strategy.

  20. Classroom processes and positive youth development: conceptualizing, measuring, and improving the capacity of interactions between teachers and students.

    Science.gov (United States)

    Pianta, Robert C; Hamre, Bridget K

    2009-01-01

    The National Research Council's (NRC) statement and description of features of settings that have value for positive youth development have been of great importance in shifting discourse toward creating programs that capitalize on youth motivations toward competence and connections with others. This assets-based approach to promote development is consistent with the Classroom Assessment Scoring System (CLASS) framework for measuring and improving the quality of teacher-student interactions in classroom settings. This chapter highlights the similarities between the CLASS and NRC systems and describes the CLASS as a tool for standardized measurement and improvement of classrooms and their effects on children. It argues that the next important steps to be taken in extending the CLASS and NRC frameworks involve reengineering assessments of teacher and classroom quality and professional development around observations of teachers' performance. This might include using observations in policies regarding teacher quality or a "highly effective teacher" that may emanate from the reauthorization of No Child Left Behind and moving away from a course or workshop mode of professional development to one that ties supports directly to teachers' practices in classroom settings.

  1. Using constructivist teaching strategies in high school science classrooms to cultivate positive attitudes toward science

    Science.gov (United States)

    Heron, Lory Elen

    This study investigated the premise that the use of constructivist teaching strategies (independent variable) in high school science classrooms can cultivate positive attitudes toward science (dependent variable) in high school students. Data regarding the relationship between the use of constructivist strategies and change in student attitude toward science were collected using the Science Attitude Assessment Tool (SAAT) (Heron & Beauchamp, 1996). The format of this study used the pre-test, post-test, control group-experimental group design. The subjects in the study were high school students enrolled in biology, chemistry, or environmental science courses in two high schools in the western United States. Ten teachers and twenty-eight classes, involving a total of 249 students participated in the study. Six experimental group teachers and four control group teachers were each observed an average of six times using the Science Observation Guide (Chapman, 1995) to measure the frequency of observed constructivist behaviors. The mean for the control group teachers was 12.89 and the mean for experimental group teachers was 20.67; F(1, 8) = 16.2, p =.004, revealing teaching behaviors differed significantly between the two groups. After a four month experimental period, the pre-test and post-test SAAT scores were analyzed. Students received a score for their difference in positive attitude toward science. The null hypothesis stating there would be no change in attitude toward science as a subject, between students exposed to constructivist strategies, and students not exposed to constructivist strategies was rejected F(1, 247) = 8.04, p =.005. The control group had a generally higher reported grade in their last science class than the experimental group, yet the control group attitude toward science became more negative (-1.18) while attitude toward science in the experimental group became more positive (+1.34) after the four-month period. An analysis of positive

    Attending a preschool center may help preschoolers with growth and development that encourage a healthy lifestyle, including sound eating behaviors. Providing a positive mealtime environment (PME) may be one of the keys to fostering a child's healthy eating habits in the classroom. However, a specific definition of a PME, the components of a PME, or directions on how to create one have not been established. The purpose of this study, therefore, was to explore Head Start teachers' perceptions related to a PME and create a conceptual framework representing these perceptions. To achieve this purpose, researchers conducted 65 in-depth phone interviews with Head Start teachers around the US. Applying principles of grounded theory, researchers developed a conceptual framework depicting teachers' perceptions of PME, consisting of five key components: (1) the people (i.e., teachers, kitchen staff, parent volunteers, and children), (2) positive emotional tone (e.g., relaxed and happy), (3) rules, expectations, and routines (e.g., family-style mealtime), (4) operations of a PME (i.e., eating, socialization, and learning), and (5) both short- and long-term outcomes of a PME. With this PME framework, researchers may be able to enhance the effectiveness of nutrition interventions related to a PME, focusing on the factors in the conceptual framework as well as barriers associated with achieving these factors.

    2015-09-01

    Full Text Available The following paper is based on a research41 made on school environments that promote learning in children. Its objective was “to determine the physical and socio-emotional factors of school environments that promote learning.” To this end, the investigation had both an exploratory and descriptive approach in terms of the various physical and emotional elements that influence the classroom environment and, therefore, the learning process. In this paper, reference is made only to the data provided by the child population. Such group was comprised of 307 boys and girls of public schools from six provinces in the country, intentionally selected through coordination and negotiation with the authorities of schools that agreed to participate. The data collection instruments used were two questionnaires with closed and open questions, an anecdotal record, and a guide on which the observation technique was performed. The analysis of the information derived from the technique and instruments used was developed by complementing quantitative data with qualitative data. Emerging categories were created to interpret the latter. The information provided by the boys and girls will hopefully serve as input to raise awareness among universities, authorities and teachers about the imperative need for school environments that are aesthetic, pleasant, motivating, comfortable, clean and promote the emotional stability every human being requires for the learning process to be successful.

    The study aimed to evaluate the classroom environment of children with low vision and provide recommendations to reduce visual stress, with focus on mainstream schooling. The medical records of 110 children (5-17 years) seen in low vision clinic during 1 year period (2015) at a tertiary care center in south India were extracted. The visual function levels of children were compared to the details of their classroom environment. The study evaluated and recommended the chalkboard visual task size and viewing distance required for children with mild, moderate, and severe visual impairment (VI). The major causes of low vision based on the site of abnormality and etiology were retinal (80%) and hereditary (67%) conditions, respectively, in children with mild (n = 18), moderate (n = 72), and severe (n = 20) VI. Many of the children (72%) had difficulty in viewing chalkboard and common strategies used for better visibility included copying from friends (47%) and going closer to chalkboard (42%). To view the chalkboard with reduced visual stress, a child with mild VI can be seated at a maximum distance of 4.3 m from the chalkboard, with the minimum size of visual task (height of lowercase letter writing on chalkboard) recommended to be 3 cm. For 3/60-6/60 range, the maximum viewing distance with the visual task size of 4 cm is recommended to be 85 cm to 1.7 m. Simple modifications of the visual task size and seating arrangements can aid children with low vision with better visibility of chalkboard and reduced visual stress to manage in mainstream schools.

    This study examines the contribution of the Responsive Classroom (RC) Approach, a set of teaching practices that integrate social and academic learning, to children's perceptions of their classroom, and children's academic and social performance over time. Three questions emerge: (a) What is the concurrent and cumulative relation between children's perceptions of the classroom and social and academic outcomes over time? (b) What is the contribution of teacher's use of RC practices to children's perceptions and social and academic outcomes? (c) Do children's perceptions of the classroom mediate the relation between RC teacher practices and child outcomes? Cross-lagged autoregressive structural equation models were used to analyze teacher and child-report questionnaire data, along with standardized test scores collected over 3 years from a sample of 520 children in grades 3-5. Results indicate a significant positive relation between RC teacher practices and child perceptions and outcomes over time. Further, children's perceptions partially mediated the relation between RC teacher practices and social competence. However, the models did not demonstrate that child perceptions mediated the relation between RC practices and achievement outcomes. Results are explained in terms of the contribution of teacher practices to children's perceptions and student performance.

    This study describes the language environment of preschool programs serving children with autism spectrum disorders (ASDs) and examines relationships between child characteristics and an automated measure of adult and child language in the classroom. The Language Environment Analysis (LENA) system was used with 40 children with ASD to collect data on adult and child language. Standardized assessments were administered to obtain language, cognitive, and autism severity scores for participants. With a mean of over 5 hours of recording across two days several months apart, there was a mean of 3.6 child vocalizations per minute, 1.0 conversational turns (in which either the adult or child respond to the other within 5 seconds) per minute, and 29.2 adult words per minute. Two of the three LENA variables were significantly correlated with language age-equivalents. Cognitive age-equivalents were also significantly correlated with two LENA variables. Autism Diagnostic Observation Schedule severity scores and LENA variables were not significantly correlated. Implications for using the LENA system with children with ASD in the school environment are discussed.

  10. Evolution and validation of a personal form of an instrument for assessing science laboratory classroom environments

    Science.gov (United States)

    Fraser, Barry J.; Giddings, Geoffrey J.; McRobbie, Campbell J.

    The research reported in this article makes two distinctive contributions to the field of classroom environment research. First, because existing instruments are unsuitable for science laboratory classes, the Science Laboratory Environment Inventory (SLEI) was developed and validated. Second, a new Personal form of the SLEI (involving a student's perceptions of his or her own role within the class) was developed and validated in conjunction with the conventional Class form (involving a student's perceptions of the class as a whole), and its usefulness was investigated. The instrument was cross-nationally fieldtested with 5,447 students in 269 senior high school and university classes in six countries, and cross-validated with 1,594 senior high school students in 92 classes in Australia. Each SLEI scale exhibited satisfactory internal consistency reliability, discriminant validity, and factorial validity, and differentiated between the perceptions of students in different classes. A variety of applications with the new instrument furnished evidence about its usefulness and revealed that science laboratory classes are dominated by closed-ended activities; mean scores obtained on the Class form were consistently somewhat more favorable than on the corresponding Personal form; females generally held more favorable perceptions than males, but these differences were somewhat larger for the Personal form than the Class form; associations existed between attitudinal outcomes and laboratory environment dimensions; and the Class and Personal forms of the SLEI each accounted for unique variance in student outcomes which was independent of that accounted for by the other form.

    Coll, Richard K.; Taylor, Neil; Fisher, Darrell L.

    2002-02-01

    The research reported in this inquiry consisted of the application of two classroom learning environment questionnaires developed in a Western context to a culturally diverse context, namely, the Pacific Islands. The College and University Classroom Environment Inventory (CUCEI) and Questionnaire on Teacher Interaction (QTI) instruments were administered to intact classes of first- and second-year science students ( n= 257) at a regional university in the Pacific Islands, containing a total of 12 ethnicities. The data reveal that the QTI instrument holds good reliability for all scales, whereas the CUCEI holds reliability for only two scales. This may be due to the simple nature of the questions on the QTI whereas the questions on the CUCEI require more interpretation, the latter exacerbated by the fact that English is a second or third language for most participants. Surprisingly, there were few differences in perceptions of teacher student interaction based on ethnicity, but substantial differences based on gender. As reported in previous classroom environment research at the secondary school level, in this study, females perceived their environment more favourably than males. The data for the QTI reveal that the students perceive their classrooms to be highly teacher dominated, consistent with previous naturalistic studies of secondary schools and exploratory studies at the tertiary level in Fiji. Since almost all the graduates from this institution become science teachers, a cycle is completed.

    The recently-built school buildings have adopted novel heat recovery ventilator and air conditioning system. Heat recovery efficiency of the heat recovery facility and energy conservation ratio of the air conditioning unit were analytically modeled, taking the ventilation networks into account. Following that, school classroom displacement ventilation and its thermal stratification and indoor air quality indicated by the CO 2 concentration have been numerically modeled concerning the effects of delivering ventilation flow rate and supplying air temperature. Numerical results indicate that the promotion of mechanical ventilation rate can simultaneously boost the dilution of indoor air pollutants and the non-uniformity of indoor thermal and pollutant distributions. Subsequent energy performance analysis demonstrates that classroom energy demands for ventilation and cooling could be reduced with the promotion of heat recovery efficiency of the ventilation facility, and the energy conservation ratio of the air conditioning unit decreases with the increasing temperatures of supplying air. Fitting correlations of heat recovery ventilation and cooling energy conservation have been presented. - Highlights: • Low energy school buildings and classroom environment. • Heat recovery facility operating with an air conditioning unit. • Displacement ventilation influenced by the heat recovery efficiency. • Energy conservation of cooling and ventilation through heat recovery. • Enhancement of classroom environment with reduction of school building energy

    2018-01-01

    Using a cooperative learning framework in a quantitative reasoning laboratory course, students were assigned to static teams of four in which they adopted roles that rotated regularly. The roles included: team leader, protocol manager, data recorder, and researcher. Using a mixed-methods approach, we investigated students' perceptions of the team roles and specifically addressed students' understanding of the roles, students' beliefs in their ability to enact the roles, and whether working with assigned team roles supported the teams to work effectively and cohesively. Although students expressed confidence in their understanding of the team roles, their understanding differed from the initial descriptions. This suggests that students' understanding of team roles may be influenced by a variety of factors, including their experiences within their teams. Students also reported that some roles appeared to lack a purpose, implying that for roles to be successful, they must have a clear purpose. Finally, the fact that many students reported ignoring the team roles suggests that students do not perceive roles as a requirement for team productivity and cohesion. On the basis of these findings, we provide recommendations for instructors wishing to establish a classroom group laboratory environment. PMID:29681667

    We examined classrooms as complex systems that affect students' literacy learning through interacting effects of content and amount of time individual students spent in literacy instruction along with the global quality of the classroom-learning environment. We observed 27 third grade classrooms serving 315 target students using two different observation systems. The first assessed instruction at a more micro-level; specifically, the amount of time individual students spent in literacy instruction defined by the type of instruction, role of the teacher, and content. The second assessed the quality of the classroom-learning environment at a more macro level focusing on classroom organization, teacher responsiveness, and support for vocabulary and language. Results revealed that both global quality of the classroom learning environment and time individual students spent in specific types of literacy instruction covering specific content interacted to predict students' comprehension and vocabulary gains whereas neither system alone did. These findings support a dynamic systems model of how individual children learn in the context of classroom literacy instruction and the classroom-learning environment, which can help to improve observations systems, advance research, elevate teacher evaluation and professional development, and enhance student achievement.

    Electric Vehicle uses electricity from batteries as fuel and is environment friendly with zero emission. The occurrence of haze in 1997 in Malaysia and neighbouring countries has called for new studies about motor vehicle emission as it aggravates the problem. In big cities like Kuala Lumpur, Penang and Johor Bahru where it is estimated that over 300,000 vehicles enter the city everyday, smoke pollution from vehicles is identified as the major contributor to air quality. One of the solutions to air pollution problem could be the use of Electric Vehicles (EV) and Natural Gas for Vehicle (NGV). The NGV uses compressed natural gas mainly methane, is lead free and clean burning with low emission. The electric vehicles use batteries as power source. These batteries are charged off-peak hour, specifically after mid-night when the electric load curve has its least demand period. The number of electric vehicles and NGV in future years is calculated considering the penetration level. The reduction in pollution is estimated considering the number of automobiles replaced by electric vehicles and NGV. Finally, it is concluded that EV and NGV could be the ultimate solution for pollution control and could improve the environment specifically that of congested cities of Malaysia. (Author)

    To implement an audience response system in a dual-campus classroom that aggregated data during graded (attendance and quizzes) and non-graded classroom activities (formative quizzes, case discussions, examination reviews, and team activities) and explore its strengths, weaknesses, and impact on active learning. After extensive research, an appropriate audience response system was selected and implemented in a dual-classroom setting for a third-year required PharmD course. Students were assigned a clicker and training and policies regarding clicker use were reviewed. Activities involving clicker use were carefully planned to simultaneously engage students in both classrooms in real time. Focus groups were conducted with students to gather outcomes data. Students and faculty members felt that the immediate feedback the automated response system (ARS) provided was most beneficial during non-graded activities. Student anxiety increased with use of ARS during graded activities due to fears regarding technology failure, user error, and academic integrity. ARS is a viable tool for increasing active learning in a doctor of pharmacy (PharmD) program, especially when used for non-graded class activities. Faculty members should proceed cautiously with using ARS for graded classroom activities and develop detailed and documented policies for ARS use.

    This study examined how the family environment predicts long-term academic and behavioral functioning in school following traumatic brain injury (TBI) in early childhood. Using a concurrent cohort, prospective design, 15 children with severe TBI, 39 with moderate TBI, and 70 with orthopedic injury (OI) who were injured when they were 3-7 years of age were compared on tests of academic achievement and parent and teacher ratings of school performance and behavior on average 6.83 years postinjury. Soon after injury and at the longer term follow-up, families completed measures of parental psychological distress, family functioning, and quality of the home environment. Hierarchical linear regression analyses examined group differences in academic outcomes and their associations with measures of the early and later family environment. The severe TBI group, but not the moderate TBI group, performed worse than did the OI group on all achievement tests, parent ratings of academic performance, and teacher ratings of internalizing problems. Higher quality early and late home environments predicted stronger academic skills and better classroom behavior for children with both TBI and OI. The early family environment more consistently predicted academic achievement, whereas the later family environment more consistently predicted classroom functioning. The quality of the home environment predicted academic outcomes more strongly than did parental psychological distress or family functioning. TBI in early childhood has long-term consequences for academic achievement and school performance and behavior. Higher quality early and later home environments predict better school outcomes for both children with TBI and children with OI. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    Full Text Available This study is part of a teacher change and improvement project whose aim is to modify the traditional teaching system in the field of Production Management (Operations Management, focusing its learning on the acquisition of the competences required by the European Higher Education Area (EHEA, in such a way that the student participates actively and is involved in the solution of the problems of real companies raised in the classroom in a virtual collaborative environment, supported in social networks through the use of different mobile devices (m-learning. Innovative methodologies such as flipped class-room, where we propose that the student begins to play an active role through problem-based collaborative learning (PBCL, whose purpose will be to train students capable of analyzing and facing problems in the same way as they would during their professional activity. However, for this methodological change to be successful, it will have to be accompanied by well-designed rubrics that allow the correct evaluation of group work and participation in the classroom. In this way, the students will know the competences achieved and those that need strengthening.

    2008-08-01

    The effects of ventilation in computer classrooms were studied with university students (n = 355) in a blinded study, 31% were women and 3.8% had asthma. Two classrooms had a higher air exchange (4.1-5.2 ac/h); two others had a lower air exchange (2.3-2.6 ac/h). After 1 week, ventilation conditions were shifted. The students reported environmental perceptions during the last hour. Room temperature, RH, CO2, PM10 and ultra-fine particles were measured simultaneously. Mean CO2 was 1185 ppm at lower and 922 ppm at higher air exchange. Mean temperature was 23.2 degrees C at lower and 22.1 degrees C at higher air exchange. After mutual adjustment (temperature, RH, CO2, air exchange), measured temperature was associated with a perception of higher temperature (P thermal comfort and air quality. Computer classrooms are crowded indoor environments with a high thermal load from both students and computer equipment. It is important to control room temperature either by air conditioning, sun shields, or sufficiently high ventilation flow. A high ventilation flow is also crucial to achieving good perceived air quality. Personal ventilation flow should be at least 10 l/s. Possible loss of learning ability due to poor indoor air quality in university buildings deserves more attention.

    2013-09-01

    Full Text Available Background: Abundant research shows that childhood adversity increases the risk for adult psychopathology while research on influences of positive family environment on risk for psychopathology is limited. Similarly, a growing body of research examines genetic and gene by environment predictors of psychopathology, yet such research on predictors of resilience is sparse. Objectives: We examined the role of positive factors in childhood family environment (CFE and the OXTR rs53576 genotype in predicting levels of adult resilient coping and positive affect. We also examined whether the relationship between positive factors in the CFEs and adult resilient coping and positive affect varied across OXTR rs53576 genotype. Methods: We gathered self-report data on childhood environment, trauma history, and adult resilience and positive affect in a sample of 971 African American adults. Results: We found that positive CFE was positively associated with higher levels of resilient coping and positive affect in adulthood after controlling for childhood maltreatment, other trauma, and symptoms of posttraumatic stress disorder. We did not find a direct effect of OXTR 53576 on a combined resilient coping/positive-affect-dependent variable, but we did find an interaction of OXTR rs53576 with family environment. Conclusions: Our data suggest that even in the face of adversity, positive aspects of the family environment may contribute to resilience. These results highlight the importance of considering protective developmental experiences and the interaction of such experiences with genetic variants in risk and resilience research.For the abstract or full text in other languages, please see Supplementary files under Article Tools online

    Nakagawa, M.; Akano, K.; Kobayashi, T.; Sekiguchi, Y.

    2017-09-01

    Image-based virtual reality (VR) is a virtual space generated with panoramic images projected onto a primitive model. In imagebased VR, realistic VR scenes can be generated with lower rendering cost, and network data can be described as relationships among VR scenes. The camera network data are generated manually or by an automated procedure using camera position and rotation data. When panoramic images are acquired in indoor environments, network data should be generated without Global Navigation Satellite Systems (GNSS) positioning data. Thus, we focused on image-based VR generation using a panoramic camera in indoor environments. We propose a methodology to automate network data generation using panoramic images for an image-based VR space. We verified and evaluated our methodology through five experiments in indoor environments, including a corridor, elevator hall, room, and stairs. We confirmed that our methodology can automatically reconstruct network data using panoramic images for image-based VR in indoor environments without GNSS position data.

    Full Text Available With a view towards a pedagogy for computer-based environments concerning distance learning and focusing on higher education, this study aimed to reveal the effects of implied meanings in the act of interpretation that idealized a synchronous and asynchronous communication tool called forchat. For discursive analysis, verbal formulations were taken from the corpus studied, which provided the themes for the sustaining principles within the dimensions of their purpose, format and use in virtual classrooms set up as learning communities. The results of the analysis highlight the uncloaking of the illusion of oneness, from the participants' immersion in the flow of the interaction, supported by another, non-capitalistic, space-time dimension for interactive exchanges. This dimension recognizes the subjects' heterogeneities and the meanings produced in the discursive order of the telematic writings.

  20. Effects of Positioning Aids on Understanding the Relationship Between a Mobile Map and the Environment

    Directory of Open Access Journals (Sweden)

    Juho Kässi

    2013-01-01

    Full Text Available Positioning technologies such as GPS enable mobile map applications to display a symbol representing an estimation of a user’s location on a mobile map, therefore acting as a positioning aid. Previous research on the cognitive processes involved in map reading suggests that map readers need at least two map–environment points (objects that are visualized on the map and perceived in the environment for determining their location on a map. Hence, the positioning aid alone does not provide enough information for self-location. Using a field experiment, we assessed the effect of representing the user’s location on a map on the cognitive processes involved in self-location. The results show that positioning aids guide the search for map–environment points and narrow the area on the map that must be scanned for self-location.

    2017-12-01

    Intact robot's navigation and accurate positioning in indoor environments are still challenging tasks. Especially in robot applications, assisting disabled and/or elderly people in museums/art gallery environments. In this paper, we present a human-like navigation method, where the neural networks control the wheelchair robot to reach the goal location safely, by imitating the supervisor's motions, and positioning in the intended location. In a museum similar environment, the mobile robot starts navigation from various positions, and uses a low-cost camera to track the target picture, and a laser range finder to make a safe navigation. Results show that the neural controller with the Conjugate Gradient Backpropagation training algorithm gives a robust response to guide the mobile robot accurately to the goal position.

    2018-01-01

    Research points to the positive impact that gender-segregated schooling and classroom initiatives exert on academic attainment. An evaluation of these studies which reveal positive effects highlights, however, that students are typically selectively assigned to single- or mixed-gender instructional settings, presenting a methodological confound. The current study controls for students' prior attainment to appraise the efficacy of a single-gender classroom initiative implemented in a co-educational high school in the United Kingdom. Secondary data analysis (using archived data) was performed on 266 middle-ability, 11-12 year-old students' standardized test scores in Languages (English, foreign language), STEM-related (Mathematics, Science, Information and Communication Technology), and Non-STEM subjects (art, music, drama). Ninety-eight students (54, 55% female) were taught in single-gender and 168 (69, 41% female) in mixed-gender classrooms. Students undertook identical tests irrespective of classroom type, which were graded in accordance with U.K national curriculum guidelines. Controlling for students' prior attainment, findings indicate that students do not appear to benefit from being taught in single-gender relative to mixed-gender classrooms in Language and STEM-related subjects. Young women benefitted from being taught in mixed-gender relative to single-gender classes for Non-STEM subjects. However, when prior ability is not controlled for, the intervention appears to be effective for all school subjects, highlighting the confounding influence of selective admissions. These findings suggest that gender-segregated classroom initiatives may not bolster students' grades. It is argued that studies that do not control for selection effects may tell us little about the effectiveness of such interventions on scholastic achievement.

Más allá de la función instrumentalista que suele asignarse a los materiales didácticos, en el presente trabajo éstos se visualizan como construcciones discursivas que pueden facultar la apropiación del pensamiento basada en el desarrollo de habilidades lingüísticas que reflejen un discurso crítico ante los diferentes reclamos (problemas históricos a los que estudiantes se ven expuestos dentro y fuera del aula. Para tal propósito, se realiza una revisión conceptual-teórica sobre la importancia y la función que los materiales tienen en el proceso de enseñanza-aprendizaje de una lengua. Bajo una perspectiva crítica, se aborda el tema de los materiales didácticos y la construcción de la motivación así como el tema de ideología y materiales didácticos. Finalmente, se concluye que en el proceso de enseñanza-aprendizaje de una lengua, los materiales didácticos son reproductores y reproducciones discursivas e ideológicas de ciertas realidades que pueden ofrecer visiones de mundo basadas en los intereses de clases dominantes si no se abordan desde posturas críticas.Abstract: The aim of this article is to state the importance teaching materials have in developing a language teaching-learning process based on the principles of the critical thinking pedagogy.

    Research shows that various stereotypes about science and science learning, such as science being filled with hard and dry content, laboratory experiments, and male-dominated work environments, have resulted in feelings of distance from science in students' minds. This study explores children's experiences of science learning and science identity. It asks how children conceive of doing science like scientists and how they develop views of science beyond the stereotypes. This study employs positioning theory to examine how children and their teacher position themselves in science learning contexts and develop science identity through classroom interactions. Fifteen students in grades 4-6 science classrooms in Western Canada participated in this study. Classroom activities and interactions were videotaped, transcribed, and analysed to examine how the teacher and students position each other as scientists in the classroom. A descriptive explanatory case analysis showed how the teacher's positioning acted to develop students' science identity with responsibilities of knowledge seeking, perseverance, and excitement about science.

    Standard, text-book based learning for earth, ocean, and atmospheric sciences has been limited by the unavailability of quantitative teaching materials. While a descriptive presentation, in a lecture format, of discrete satellite images is often adequate for high school classrooms, this is seldom the case at the undergraduate level. In order to address these concerns, a series of numerical exercises for the Macintosh was developed for use with satellite-derived Sea Surface Temperature, pigment and sea ice concentration data. Using a modified version of NIH Image, to analyze actual satellite data, students are able to better understand ocean processes, such as circulation, upwelling, primary production, and ocean/atmosphere coupling. Graphical plots, image math, and numerical comparisons are utilized to substantiate temporal and spatial trends in sea surface temperature and ocean color. Particularly for institutions that do not offer a program in remote sensing, the subject matter is presented as modular units, each of which can be readily incorporated into existing curricula. These materials have been produced in both CD-ROM and WWW format, making them useful for classroom or lab setting. Depending upon the level of available computer support, graphics can be displayed directly from the CD-ROM, or as a series of color view graphs for standard overhead projection.

  7. Influence of Psychosocial Classroom Environment on Students' Motivation and Self-Regulation in Science Learning: A Structural Equation Modeling Approach

    2013-04-01

    The primary aim of this study was two-fold: 1) to identify salient psychosocial features of the classroom environment that influence students' motivation and self-regulation in science learning; and 2) to examine the effect of the motivational constructs of learning goal orientation, science task value and self-efficacy in science learning on students' self-regulation in science classrooms. Data collected from 1360 science students in grades 8, 9 and 10 in five public schools in Perth, Western Australia were utilized to validate the questionnaires and to investigate the hypothesized relationships. Structural Equation Modeling analysis suggested that student cohesiveness, investigation and task orientation were the most influential predictors of student motivation and self-regulation in science learning. In addition, learning goal orientation, task value and self-efficacy significantly influenced students' self-regulation in science. The findings offer potential opportunities for educators to plan and implement effective pedagogical strategies aimed at increasing students' motivation and self-regulation in science learning.

    2003-01-01

    Learning-in-context is a much-discussed topic in medical education. Information is said to be better recalled when the learning environment resembles the later retrieval environment. Godden and Baddeley (1975) showed that divers recalled words better when the recall condition matched the original learning environment, i.e. underwater or on land. Though it is unclear whether the findings can be generalized for medical education, medical educators regularly refer to them. We replicated the Godden and Baddeley study in ecologically more valid conditions for medical education and extended it with meaningful subject matter (namely, a patient case description). Sixty-three clerks were randomized over four conditions, contrasting a clinical (bedside) with an educational (classroom) environment as both learning and recall conditions. Students were asked to recall a list of words and a patient case in the same environment or in the opposite environment as where they learned it. We failed to find a significant same-context advantage for free recall of the list of words and the patient case propositions. However, there does appear to be a slight tendency towards better recall of the case description when learning took place in the clinical environment. In medical education, the context, if conceived as physical surroundings, does not seem to contribute to a same-context advantage. One should be cautious in generalizing the findings of Godden and Baddeley. However, different forms of 'context' other than the physical one used in the Godden and Baddeley study may well enhance learning effects in medical education.

    Brown, Jo

    2010-06-01

    To better understand the transfer of classroom-learned clinical communication skills (CCS) to the clinical environment of the hospital ward, where they are practiced and refined by students. The author first briefly presents the literature on clinical communication, provides an overview of the debates around the notion of transfer, and presents a sociocultural model of developmental transfer applied to CCS learning. Second, she describes a focus group and nine individual interviews carried out with 17 fourth-year medical students at one medical school in the United Kingdom in 2008. The goal was to elicit their views of CCS teaching, learning, and transfer of CCS to the clinical workplace. The findings are presented under the four main themes of transition, where students experienced the transition from the medical school to the hospital ward as a mixture of positive and negative impacts on transferring their CCS skills; the clinical culture, where senior doctors had the greatest impact on student learning and emergent clinical practice; clinical communication as a vehicle for professionalism and being a "good" doctor; and, finally, transfer mechanisms, where simulated practice with actors and the clinical history template were powerful learning tools. Findings indicate that more needs to be done to support, develop, and embed CCS into the professional practice of medical students in the clinical workplace. This may be achieved by greater collaboration of educators in the academic and clinical environments. Using the developmental transfer model applied to CCS learning may help foster this relationship.

    Features of the physical environment have an impact on the human behaviour. Thus, planners and policymakers around the world should aim at providing environments that are perceived as being of good quality, in which the residents enjoy spending time and moving around in. It is widely acknowledged that urban environmental quality associates with well-being, but there is currently very little research examining which features of urban environments people of different ages perceive as appealing in their living environments. Individuals experience different age-related developmental environments throughout their life course. Thus, the usage and perceptions of different spaces can also differ between various age groups. Public Participation GIS datasets collected in 2009 and 2011 in Helsinki Metropolitan Area were used to study places perceived as being positive by adults (n=3119) and children (n=672). Participants marked points on a map that were overlaid with GIS data to study whether the physical environment of positive places of different age groups differed. The results demonstrated that the physical environment differs significantly in the positive places of different age groups. The places of adult age groups were characterized by green, blue and commercial spaces, whereas sports, residential and commercial spaces characterize children's and adolescents' places. Older adults' places were found to be closest to home, while adolescents' places were the most distant. Providing appealing environments for all age groups in one setting remains problematic but should nevertheless be strived for, especially in the urban context where a constant competition over different usages of space occurs.

    Full Text Available The changes in learning management typically involve the introduction of various alternative learning methods. The development of an effective learning experience requires the modification of conventional learning. Teaching and learning constructively synchronize instructions and assessment toward the desired learning outcomes. Notwithstanding the vast literature on the creation of effective learning, the lack of explanation on how the relationship between effective teaching and effective classroom would likely leave practitioners and academia without a clear guidance on how to operationalize the creation of effective learning in real life. A systematic literature review procedure was conducted upon published papers between 2007 and 2015 in outstanding education journals. This paper contributes to the literature by amassing the knowledge on pedagogical practices in effective learning creation. In addition, to obtain a granular elaboration about the matter, a framework to operationalize the creation of effective learning is suggested. Three aspects compose the framework namely teachers' intrinsic capabilities, educational institution support, and student’s participative involvement. The roles of each party were extracted from the knowledge contained in the reviewed literature.   This work is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License.

    Full Text Available Online study has increasingly become more attractive to students at university level due to convenience access to their instructors and to study resources. This study has developed online social network for study. It proposes to provide lesson content availability, past lecture, by sending online study lesson media to students’ mobile phone or tablet. Approximately 85 undergraduate software engineering students participated for 1.5 semesters. In comparing the use of the study toll, and without the tool, the alterations were found between traditional classroom learning style and online study. Also, the study’s aim was to attest the online study tool’s efficiency. However, these results were not obvious when the achievement factor was controlled by the limitation of time. The primary purpose of this study is to evaluate these two groups of students with extended experiment time for a noticeable result by used questionnaires course examination, and inventory of ILP learning process. The observed, shows that students with online study tools scored higher on course examinations after measures by the mentioned methodology.

    Full Text Available This study investigates holistic craft processes in craft education with an instrument for data-collection and self-assessment. Teaching in a study context is based on co-teaching and a design process, highlighted by the Finnish Basic Education Core Curriculum 2014. The school architecture and web-based learning environment is combined. Division for textiles and technical work is no longer supported in this multimaterial learning environment. The aim of the study is to 1 make pupils’ holistic craft processes visible in everyday classroom practices with information collected by a mobile-application and 2 point out the curriculum topics that are covered during everyday classroom practices as defined by the teachers. The data is collected using an Experience Sampling Method with a gamified learning analytics instrument. Teachers’ classroom activities were used as the backbone for the thematic mapping of the craft curriculum. Preliminary measurements were carried out in a Finnish primary school in grades 5–6 (age 10–12, n = 125 during a four-week period in October-November 2016. The list of classroom activities was updated after the four weeks’ experiment and was tested in March-May 2017 with all the pupils of the pilot school (N = 353. The key findings were that a for pupils the self-assessment was easy as a technical process but there were several factors in the everyday classroom settings that made the process challenging and b it was relatively difficult for teachers to describe the classroom activities in terms of the new curriculum; however, after four weeks they could not only described the activities in more details but had also developed new activities that supported the ideas of the new curriculum better.Keywords: multi-material craft, learning environment, holistic craft process, experience sampling method

    Full Text Available The Global Positioning System demonstrates the significance of Location Based Services but it cannot be used indoors due to the lack of line of sight between satellites and receivers. Indoor Positioning Systems are needed to provide indoor Location Based Services. Wireless LAN fingerprints are one of the best choices for Indoor Positioning Systems because of their low cost, and high accuracy, however they have many drawbacks: creating radio maps is time consuming, the radio maps will become outdated with any environmental change, different mobile devices read the received signal strength (RSS differently, and peoples’ presence in LOS between access points and mobile device affects the RSS. This research proposes a new Adaptive Indoor Positioning System model (called DIPS based on: a dynamic radio map generator, RSS certainty technique and peoples’ presence effect integration for dynamic and multi-floor environments. Dynamic in our context refers to the effects of people and device heterogeneity. DIPS can achieve 98% and 92% positioning accuracy for floor and room positioning, and it achieves 1.2 m for point positioning error. RSS certainty enhanced the positioning accuracy for floor and room for different mobile devices by 11% and 9%. Then by considering the peoples’ presence effect, the error is reduced by 0.2 m. In comparison with other works, DIPS achieves better positioning without extra devices.

  3. Using online pedagogy to explore student experiences of Science-Technology-Society-Environment (STSE) issues in a secondary science classroom

    Ayyavoo, Gabriel Roman

    With the proliferation of 21st century educational technologies, science teaching and learning with digitally acclimatized learners in secondary science education can be realized through an online Science-Technology-Society-Environment (STSE)-based issues approach. STSE-based programs can be interpreted as the exploration of socially-embedded initiatives in science (e.g., use of genetically modified foods) to promote the development of critical cognitive processes and to empower learners with responsible decision-making skills. This dissertation presents a case study examining the online environment of a grade 11 physics class in an all-girls' school, and the outcomes from those online discursive opportunities with STSE materials. The limited in-class discussion opportunities are often perceived as low-quality discussions in traditional classrooms because they originate from an inadequate introduction and facilitation of socially relevant issues in science programs. Hence, this research suggests that the science curriculum should be inclusive of STSE-based issue discussions. This study also examines the nature of students' online discourse and, their perceived benefits and challenges of learning about STSE-based issues through an online environment. Analysis of interviews, offline classroom events and online threaded discussion transcripts draws from the theoretical foundations of critical reflective thinking delineated in the Practical Inquiry (P.I.) Model. The PI model of Cognitive Presence is situated within the Community of Inquiry framework, encompassing two other core elements, Teacher Presence and Social Presence. In studying Cognitive Presence, the online STSE-based discourses were examined according to the four phases of the P.I. Model. The online discussions were measured at macro-levels to reveal patterns in student STSE-based discussions and content analysis of threaded discussions. These analyses indicated that 87% of the students participated in

    Nurturing environments within the context of families, schools, and communities all play an important role in enhancing youth's behavioral choices and health outcomes. The increasing prevalence rates of obesity among youth, especially among low income and ethnic minorities, highlight the need to develop effective and innovative intervention approaches that promote positive supportive environments across different contexts for at-risk youth. We propose that the integration of Social Cognitive Theory, Family Systems Theory, and Self-Determination Theory offers a useful framework for understanding how individual, family, and social-environmental-level factors contribute to the development of nurturing environments. In this paper, we summarize evidence-based randomized controlled trials that integrate positive parenting, motivational, and behavioral skills strategies in different contexts, including primary care, home, community, and school-based settings. Taken together, these studies suggest that youth and parents are most likely to benefit when youth receive individual-level behavioral skills, family-level support and communication, and autonomous motivational support from the broader social environment. Future investigators and healthcare providers should consider integrating these evidence-based approaches that support the effects of positive social climate-based interventions on promoting healthy eating, physical activity, and weight management in youth.

  5. RELATIVE PANORAMIC CAMERA POSITION ESTIMATION FOR IMAGE-BASED VIRTUAL REALITY NETWORKS IN INDOOR ENVIRONMENTS

    2017-09-01

    Full Text Available Image-based virtual reality (VR is a virtual space generated with panoramic images projected onto a primitive model. In imagebased VR, realistic VR scenes can be generated with lower rendering cost, and network data can be described as relationships among VR scenes. The camera network data are generated manually or by an automated procedure using camera position and rotation data. When panoramic images are acquired in indoor environments, network data should be generated without Global Navigation Satellite Systems (GNSS positioning data. Thus, we focused on image-based VR generation using a panoramic camera in indoor environments. We propose a methodology to automate network data generation using panoramic images for an image-based VR space. We verified and evaluated our methodology through five experiments in indoor environments, including a corridor, elevator hall, room, and stairs. We confirmed that our methodology can automatically reconstruct network data using panoramic images for image-based VR in indoor environments without GNSS position data.

    Full Text Available This paper presents an experience applied to a public university campus using Data Envelopment Analysis (DEA to evaluate and improve the energy efficiency of the indoor spaces of the buildings within the limits of the Federal University of Piauí, considering the lighting (installed power and luminous flux and air conditioning (absorbed electric power and cooling capacity input/output variables. Using Brazilian energy efficiency evaluation methods, a comparison was made between DEA and Brazilian standards, with the goal of examining DEA’s performance and feasibility in efficiency improvement. The results revealed that all of the analyzed university classrooms were inefficient, which is coherent with the classification obtained by applying Brazilian standards; the calculated efficiency scores for these rooms varied from 0.7182 to 0.8477, a 0.7848 average. The DEA model, while operating in lighting and air conditioning systems, achieved a reduction of installed power of 43.5% and 22.7%, respectively, totaling a decrease of 25.6%, being able to maintain the standard characteristics of the systems mentioned. According to the DEA models, it was found that the generated targets effectively improved the efficiency of lighting and air-conditioning systems, reducing excessive inputs such as air conditioners’ consumption and increasing deficient outputs such as luminous flux. It is possible to expand this successful application in the layout of the building in the whole campus area to concept small smart city projects; both have been achieved in the public buildings of the administrative body. Results from this paper revealed DEA’s potential in assessing and optimizing the energy efficiency of buildings, improving their sustainability indexes, acting as a tool to support decision-making and benchmarking.

    Full Text Available Background: At many Polish hospitals, insufficient attention is given to positive work environment. In many cases nurses, similarly to the representatives of other professional groups, are not provided with facilities or tools to perform their professional tasks in safe conditions. The aspects of recruitment and retention of employees are often ignored. The aim of this study has been to assess the chosen determinants of work environment of nurses in Poland using the concept of the Positive Practice Environments (PPE. Material and Methods: The survey was carried out from 2008 to 2011 among 1049 nursing students of 3 randomly selected public medical universities that provided nursing education at the graduate level of the Master of Science. All the people qualified for the study group were practising nurses or midwives. The Polish Nursing Association coordinated the project, obtained the tool, translated it and adjusted it to the Polish conditions. The areas covered in the survey were: a place of employment, selected physical and social elements influencing the work conditions, and biographical information. Results: Access to as many as 8 factors identified as attributes of friendly environments was found unsatisfactory by over 50% of the nurses. For the purpose of objective assessment, the results were compared with the results obtained in the group of nurses in England. Conclusions: The majority of the surveyed nurses were not satisfied with their work environments. Polish nurse managers should ensure that aspects of recognized attributes of friendly, positive practice environments for nurses are established to support nurses’ satisfaction as a pre-condition for patients’ safety.

  20. Linear equations and rap battles: how students in a wired classroom utilized the computer as a resource to coordinate personal and mathematical positional identities in hybrid spaces

    Science.gov (United States)

    Langer-Osuna, Jennifer

    2015-03-01

    This paper draws on the constructs of hybridity, figured worlds, and cultural capital to examine how a group of African-American students in a technology-driven, project-based algebra classroom utilized the computer as a resource to coordinate personal and mathematical positional identities during group work. Analyses of several vignettes of small group dynamics highlight how hybridity was established as the students engaged in multiple on-task and off-task computer-based activities, each of which drew on different lived experiences and forms of cultural capital. The paper ends with a discussion on how classrooms that make use of student-led collaborative work, and where students are afforded autonomy, have the potential to support the academic engagement of students from historically marginalized communities.

    A space materials exposure experiment was condcuted on the exterior of the Russian Service Module (SM) of the International Space Station (ISS) using the Micro-Particles Capturer and Space Environment Exposure Device (MPAC&SEED) of the Japan Aerospace Exploration Agency (JAXA). Results reveal artificial environment effects such as sample contamination, attitude change effects on AO fluence, and shading effects of UV on ISS. The sample contamination was coming from ISS components. The particles attributed to micrometeoroids and/or debris captured by MPAC might originate from the ISS solar array. Another MPAC&SEED will be aboard the Exposure Facility of the Japanese Experiment Module, KIBO Exposure Facility (EF) on ISS. The JEM/MPAC&SEED is attached to the Space Environment Data Acquisition Equipment-Attached Payload (SEDA-AP) and is exposed to space. Actually, SEDA-AP is a payload on EF to be launched by Space Shuttle flight 2J/A. In fact, SEDA-AP has space environment monitors such as a high-energy particle monitor, atomic oxygen monitor, and plasma monitor to measure in-situ natural space environment data during JEM/MPAC&SEED exposure. Some exposure samples for JEM/MPAC&SEED are identical to SM/MPAC&SEED samples. Consequently, effects on identical materials at different positions and operation periods of ISS will be evaluated. This report summarizes results from space environment monitoring samples for atomic oxygen analysis on SM/MPAC&SEED, along with experimental plans for JEM/MPAC&SEED.

    A teleoperation system based on virtual environment (VE) is an emergent technology for operating a robot in remote or hazardous environment. We have developed a VE-based teleoperation system for robot-arm manipulation in a simplified real world. The VE for manipulating the robot arm is constructed by measuring the 3D positions of the objects around the robot arm by motion-stereo method. The 3D position is estimated by using two-(calibration) planes method based on images captured by the CCD camera on the robot-arm, since the two-planes method does not need pin-hole-model assumption to the camera system. The precision of this 3D-measurement is evaluated through experiments and then derived is the theoretical model to the error in the measurement. This measurement system is applied to VE-based teleoperation experiment for Peg-in-hole practice by the robot arm. (author)

  3. Facilitating Geoscience Education in Higher-Education Institutes Worldwide With GeoBrain -- An Online Learning and Research Environment for Classroom Innovations

    Deng, M.; di, L.

    2006-12-01

    Higher education in geosciences has imminent goals to prepare students with modern geoscience knowledge and skills to meet the increased demand on trained professionals for working on the big challenges faced by geoscience disciplines, such as the global environmental change, world energy supplies, sustainable development, etc. In order to reach the goal, the geoscience education in post-secondary institutes worldwide has to attract and retain enough students and to train students with knowledge and skills needed by the society. The classroom innovations that can encourage and support student investigations and research activities are key motivation mechanisms that help to reach the goal. This presentation describes the use of GeoBrain, an innovative geospatial knowledge system, as a powerful educating tool for motivating and facilitating innovative undergraduate and graduate teaching and research in geosciences. Developed in a NASA funded project, the GeoBrain system has adopted and implemented the latest Web services and knowledge management technologies for providing innovative methods in publishing, accessing, visualizing, and analyzing geospatial data and in building/sharing geoscience knowledge. It provides a data-rich online learning and research environment enabled by wealthy data and information available at NASA Earth Observing System (EOS) Data and Information System (EOSDIS). Students, faculty members, and researchers from institutes worldwide can easily access, analyze, and model with the huge amount of NASA EOS data just like they possess such vast resources locally at their desktops. The online environment provided by GeoBrain has brought significant positive changes to geosciences education in higher-education institutes because of its new concepts and technologies, motivation mechanisms, free exploration resources, and advanced geo- processing capabilities. With the system, the used-to-be very challenging or even impossible teaching tasks has

  4. Encouraging Classroom Discussion

    2014-10-01

    Full Text Available Classroom discussion has the potential to enhance the learning environment and encourages students to become active participants in the educational process. Student participation in classroom discussion has been shown to significantly improve the student learning experience. Research suggests that classroom discussion is an effective method for encouraging student classroom participation and for motivating student learning beyond the classroom. Participation in classroom discussion encourages students to become active collaborators in the learning process, while at the same time providing instructors with a practical method of assessing student learning. Classroom discussion is an effective tool for developing higher-level cognitive skills like critical thinking. Despite the potential discussion holds for student learning, many in academia lament the lack of participation in the classroom. The lack of student participation in classroom discussion is not a recent problem; it is one that has frustrated instructors for decades. Instructors report that some of the more current methods for encouraging classroom discussion can be exasperating and at times non-productive. This two-year study of 510 college and university students provides insight into the reasons why some students do not participate in classroom discussion. This study, which also elicited input from sixteen college and university professors and two high school teachers, offers some suggestions for creating and encouraging an environment conducive to student participation in the classroom.

    The family food environment is an important influence in the development of children's dietary habits. Research suggests that influences of current dietary behaviour and behaviour change may differ. The aims of this paper were to: (1) investigate the association between the food environment at baseline and change in children's saturated fat intake; and (2) to explore whether a change in the food environment was associated with a change in children's saturated fat intake. Secondary analysis of a 12 week cluster randomised controlled trial in 133 4-13 year old children. Families were randomly allocated to parental education regarding changing to reduced-fat dairy foods or a comparison non-dietary behaviour. The interventions were family focused. Parents received education from a dietitian in 3x30 minute sessions to facilitate behaviour change. Parents completed a comprehensive questionnaire capturing three domains of the food environment--Parent knowledge and attitudes; shaping practices; and behaviours and role modelling. Children's dietary intake was assessed via multiple 24-hour recalls at baseline and week 12. Changes in the family food environment and primary outcome (saturated fat) were calculated. Hierarchical linear regression models were performed to explore the association between baseline and change in food environment constructs and change in saturated fat intake. Standardised Beta are presented (pchange in saturated fat. An increase in nutrition knowledge (β=-0.2), perceived responsibility (β=-0.3) and restriction (β=-0.3) from baseline to week 12 were associated with greater reduction in saturated fat intake. The present study was one of the first to quantify changes in the family food environment, and identify a number of factors which were associated with a positive dietary change. Because interventions focus on behaviour change, the findings may provide specific targets for intervention strategies in the future. Australia New Zealand Clinical

    Full Text Available Purpose: To study the relationship between sleep position and ocular surface symptoms and signs in an high air flow environment. Methods: Prospective observational study of new patients attending the dry eye clinic was performed. Patients with pre-existing ocular history, relevant systemic history (e.g. Sjogren’s syndrome or who were using topical or systemic therapy for dry eye were not included. Data were collected from the patient to document their dry eye symptoms; preferred dependent sleeping side and their bedroom airflow. All patients were examined by a clinician blind to the patient’s responses where Schirmer’s test and slit lamp examination were performed looking for the presence of lagophthalmos and corneal epitheliopathy. Results: 48 patients enrolled into the study of which 23 were males and 25 were females with a normal and comparable age distribution. The study found a strong association between patients’ preferred sleeping side and the incidence of corneal epitheliopathy in the contralateral eye particularly in patients with evidence of lagophthalmos. Dry eye symptoms were found to be worse and tear production lower on the contralateral side to the preferred sleeping side particularly in patients who sleep in a high airflow environment. Conclusion: In patients sleeping in a high airflow environment with nocturnal lagophthalmos, this study observed an association between preferred dependent sleep position and increased dry eye symptoms, lower Schirmer’s scores and increased corneal epitheliopathy in the contralateral eye.

    Weight bias can negatively impact health, and schools may be risky environments for students with obesity. We aimed to explore teachers' perceptions of the school experiences and academic challenges of students with obesity. We conducted interviews with 22 teachers in the Northeast, mid-Atlantic, and Midwest in July-August 2014. All interviews were transcribed verbatim, coded, and analyzed for important themes by two researchers using the immersion/crystallization approach. Most teachers felt that students with obesity were more likely to have academic difficulties. Two main perceptions of the reasons for these difficulties emerged: (1) obesity led to lower self-esteem that caused students to participate less, and (2) poorer nutrition, increased screen time, and reduced physical activity were simultaneously causing obesity and poorer academic performance. A few teachers described colleagues who felt students with obesity were not as motivated to work hard in school as their peers. Many teachers described school health promotion efforts focused on weight reduction that could exacerbate weight stigma and risk of disordered eating. Students with obesity, particularly girls, may be at risk for negative social and academic experiences in K-12 schools and may be perceived as struggling academically by their teachers.

    Affective neuroscience, incorporating neurophysiology and neuropsychology, is providing increasing evidence that certain behaviours of animals may be interpreted in terms of what they are intending to achieve, i.e. their goals. It is also providing evidence that allows inferences to be made about the affective contents of some goal-directed behaviours. These neuroscience-supported inferences are aligned with recommendations based on prior behaviour-based investigations of animals' preferences, aversions and priorities, and these observations together support the cautious use of particular behaviours to infer what the accompanying affects may be. In this review, therefore, some attention is given to negative affects and their relationships to poor animal welfare, but the primary focus is the positive affects animals may experience when they successfully engage in rewarding goal-directed behaviours, encapsulated in the concept of positive affective engagement. The review draws together reports of environment-focused and animal-to-animal interactive behaviours observed in a range of species and under diverse circumstances in order to illustrate the likely widespread occurrence of the positive affects that may accompany them. Particular consideration is given to affects that are potentially associated with some aspects of exploration and food acquisition in stimulus rich or impoverished environments, and to those that may be associated with aspects of the affiliative interactions of bonding or bond affirmation, maternal care, play and sexual activity. It is concluded that animals given the opportunity to engage in such activities may experience some positive affects. However, the intensity of an animal's experience of particular positive affects is likely to range from zero to very high because the associated behaviours occur intermittently, variation may occur during different phases of a goal-directed behaviour, and other positive or negative affects experienced at

    Fish species inhabitating seawater (SW) or freshwater (FW) habitats have to develop genetic adaptations to alternative environment factors, especially salinity. Functional consequences of the protein variations associated with habitat environments in fish mitochondrial genomes have not yet received much attention. We analyzed 829 complete fish mitochondrial genomes and compared the amino acid differences of 13 mitochondrial protein families between FW and SW fish groups. We identified 47 specificity determining sites (SDS) that associated with FW or SW environments from 12 mitochondrial protein families. Thirty-two (68%) of the SDS sites are hydrophobic, 13 (28%) are neutral, and the remaining sites are acidic or basic. Seven of those SDS from ND1, ND2 and ND5 were scored as probably damaging to the protein structures. Furthermore, phylogenetic tree based Bayes Empirical Bayes analysis also detected 63 positive sites associated with alternative habitat environments across ten mtDNA proteins. These signatures could be important for studying mitochondrial genetic variation relevant to fish physiology and ecology.

    Full Text Available The paper addresses the importance of postural attitude in environmental ergonomics considering that ergonomics is a multidisciplinary discipline that studies the systemic interactions between human machine in the development of different physical activities in their environment with the purpose of obtaining a state health, safety, mechanical efficiency and productivity to prevent repetitive strain injuries, positions held and musculoskeletal problems which can develop over time and can reach disabilities short or long term. Considering the influence of the environment on man to work: thermal, sound, light environments and its impact on health; anthropometric and biomechanical data: measures of bone, amplitudes segments of joint movements; the characteristics of muscular effort: The efficiency and effectiveness in physical activities in its various manifestations is contingent on first order to study the physical conditions such as; thermal environment, noise levels, air conditioning level, vibration hygienic conditions, including conditions schedules and secondly the attitude that sums the man in front of the activities which in one way or another affect job performance. It addresses the influence of postural attitude in environmental ergonomics while performing physical activities of man from the importance and prevalence of health problems related to the non-application of standards of environmental ergonomics.

  12. MAPPING GNSS RESTRICTED ENVIRONMENTS WITH A DRONE TANDEM AND INDIRECT POSITION CONTROL

    Full Text Available The problem of autonomously mapping highly cluttered environments, such as urban and natural canyons, is intractable with the current UAV technology. The reason lies in the absence or unreliability of GNSS signals due to partial sky occlusion or multi-path effects. High quality carrier-phase observations are also required in efficient mapping paradigms, such as Assisted Aerial Triangulation, to achieve high ground accuracy without the need of dense networks of ground control points. In this work we consider a drone tandem in which the first drone flies outside the canyon, where GNSS constellation is ideal, visually tracks the second drone and provides an indirect position control for it. This enables both autonomous guidance and accurate mapping of GNSS restricted environments without the need of ground control points. We address the technical feasibility of this concept considering preliminary real-world experiments in comparable conditions and we perform a mapping accuracy prediction based on a simulation scenario.

    This study compared the responses of on-site, remote-site, and traditional classroom students on measures of student/teacher interaction, course structure, physical learning environment, and overall course enjoyment/satisfaction. The sample population consisted of students taking undergraduate courses in medical terminology at two western colleges. The survey instrument was derived from Thomerson's questionnaire, which included closed- and open-ended questions assessing perceptions of students toward their courses. Controlling for grade expectations, results revealed no significant differences among the on-site, remote-site, and traditional classroom students in any of the four cluster domains. However, a nonsignificant (and continuing) trend suggested that students preferred the traditional classroom environment. When results were controlled for age, significant differences emerged between traditional and nontraditional students on measures of student/teacher interaction, physical learning environment, and overall enjoyment/satisfaction, as nontraditional students exhibited higher scores. Students' responses to open-ended questions indicated they enjoyed the convenience of online instruction, but reported finding frustration with technology itself.

    2015-01-01

    The Ironless Inductive Position Sensor (I2PS) has been introduced as a valid alternative to Linear Variable Differential Transformers (LVDTs) when external magnetic fields are present. Potential applications of this linear position sensor can be found in critical systems such as nuclear plants, tokamaks, satellites and particle accelerators. This paper analyzes the performance of the I2PS in the harsh environment of the collimators of the Large Hadron Collider (LHC), where position uncertainties of less than 20 μm are demanded in the presence of nuclear radiation and external magnetic fields. The I2PS has been targeted for installation for LHC Run 2, in order to solve the magnetic interference problem which standard LVDTs are experiencing. The paper describes in detail the chain of systems which belong to the new I2PS measurement task, their impact on the sensor performance and their possible further optimization. The I2PS performance is analyzed evaluating the position uncertainty (on 30 s), the magnetic im...

Joint position sense, which is crucial for balance and gait control, is also affected in stroke patients. To compare the effect of two exercise training protocols (walking in deep water and on a treadmill on the knee position sense of stroke patients. METHODS This study was designed as a randomized controlled clinical trial. Twelve adults, who suffered a stroke at least one year prior to the start of the study, were randomly assigned to one of two groups: 1 pool group submitted to aerobic deep water walking training; and 2 the treadmill group which was submitted to aerobic walk on a treadmill. Measurements: The position sense, absolute error and variable error, of the knee joint was evaluated prior to and after nine weeks of aerobic training. RESULTS The pool group presented smaller absolute (13.9o versus 6.1o; p < 0.05 and variable (9.2o versus 3.9o; p < 0.05 errors after nine-weeks gait training than the treadmill group. CONCLUSIONS Nine-week aerobic exercise intervention in aquatic environment improved precision in the position sense of the knee joint of stroke patients, suggesting a possible application in a rehabilitation program.

  17. Intending to stay: Positive images, attitudes, and classroom experiences as influences on students' intentions to persist in science and engineering majors

    Wyer, Mary Beth

    2000-10-01

    Contemporary research on persistence in undergraduate education in science and engineering has focused primarily on identifying the structural, social, and psychological barriers to participation by students in underrepresented groups. As a result, there is a wealth of data to document why students leave their majors, but there is little direct empirical data to support prevailing presumptions about why students stay. Moreover, researchers have used widely differing definitions and measures of persistence, and they have seldom explored field differences. This study compared three ways of measuring persistence. These constituted three criterion variables: commitment to major, degree aspirations, and commitment to a science/engineering career. The study emphasized social factors that encourage students to persist, including four predictor variables---(1) positive images of scientists/engineers, (2) positive attitudes toward gender and racial equality, (3) positive classroom experiences, and (4) high levels of social integration. In addition, because researchers have repeatedly documented the degree to which women are more likely than men to drop out of science and engineering majors, the study examined the potential impact of gender in relation to these predictor variables. A survey was administered in the classroom to a total of 285 students enrolled in a required course for either a biological sciences and or an engineering major. Predictor variables were developed from standard scales, including the Images of Science/Scientists Scale, the Attitudes toward Women Scale, the Women in Science Scale, and the Perceptions of Prejudice Scale. Based on logistic regression models, results indicate that positive images of scientists and engineers was significantly related to improving the odds of students having a high commitment to major, high degree aspirations, and high commitment to career. There was also evidence that positive attitudes toward gender and racial equality

  3. A positioning system with no line-of-sight restrictions for cluttered environments

    Science.gov (United States)

    Prigge, Eric A.

    Accurate sensing of vehicle location and attitude is a fundamental requirement in many mobile-robot applications, but is a very challenging problem in the cluttered and unstructured environment of the real world. Many existing indoor positioning systems are limited in workspace and robustness because they require clear lines of sight or do not provide absolute, drift-free measurements. Examples include overhead vision systems, where an unobstructed view must be maintained between robot and camera, and inertial systems, where the measurements drift over time. The research presented in this dissertation provides a new location- and attitude-sensing system designed specifically to meet the challenges of operation in a realistic, cluttered indoor environment, such as that of an office building or warehouse. The system is not limited by line-of-sight restrictions and produces drift-free measurements throughout a three-dimensional operating volume that can span a large building. Accuracy of several centimeters and a few degrees is delivered at 10 Hz, and any number of the small sensor units can be in operation, all providing estimates in a common reference frame. This positioning system is based on extremely-low-frequency magnetic fields, which have excellent characteristics for penetrating line-of-sight obstructions. Beacons located throughout the workspace create the low-level fields. A sensor unit on the mobile robot samples the local magnetic field and processes the measurements to determine its location and attitude. This research overcomes limitations in existing magnetic-based systems. The design of the signal structure, based on pseudorandom codes, enables the use of multiple, distributed L-beacons and greatly expands coverage volume. The development of real-time identification and correction methods mitigates the impact of distortions caused by materials in the environment. A novel solution algorithm combats both challenges, providing increased coverage volume

    Full Text Available In this paper, a system for 3D position estimation in wide, unconstrained indoor environments is presented that employs infrared optical outside-in tracking of rigid-body targets with a stereo camera rig. To overcome limitations of state-of-the-art optical tracking systems, a pipeline for robust target identification and 3D point reconstruction has been investigated that enables camera calibration and tracking in environments with poor illumination, static and moving ambient light sources, occlusions and harsh conditions, such as fog. For evaluation, the system has been successfully applied in three different wide and unconstrained indoor environments, (1 user tracking for virtual and augmented reality applications, (2 handheld target tracking for tunneling and (3 machine guidance for mining. The results of each use case are discussed to embed the presented approach into a larger technological and application context. The experimental results demonstrate the system’s capabilities to track targets up to 100 m. Comparing the proposed approach to prior art in optical tracking in terms of range coverage and accuracy, it significantly extends the available tracking range, while only requiring two cameras and providing a relative 3D point accuracy with sub-centimeter deviation up to 30 m and low-centimeter deviation up to 100 m.

  5. Modelling and Control of Stepper Motors for High Accuracy Positioning Systems Used in Radioactive Environments

    CERN Document Server

    Picatoste Ruilope, Ricardo; Masi, Alessandro

    Hybrid Stepper Motors are widely used in open-loop position applications. They are the choice of actuation for the collimators in the Large Hadron Collider, the largest particle accelerator at CERN. In this case the positioning requirements and the highly radioactive operating environment are unique. The latter forces both the use of long cables to connect the motors to the drives which act as transmission lines and also prevents the use of standard position sensors. However, reliable and precise operation of the collimators is critical for the machine, requiring the prevention of step loss in the motors and maintenance to be foreseen in case of mechanical degradation. In order to make the above possible, an approach is proposed for the application of an Extended Kalman Filter to a sensorless stepper motor drive, when the motor is separated from its drive by long cables. When the long cables and high frequency pulse width modulated control voltage signals are used together, the electrical signals difer greatl...

    In this paper, we address the problem of vehicle localization in urban environments. We rely on visual odometry, calculating the incremental motion, to track the position of the vehicle and on place recognition to correct the accumulated drift of visual odometry, whenever a location is recognized. The algorithm used as a place recognition module is SeqSLAM, addressing challenging environments and achieving quite remarkable results. Specifically, we perform the long-term navigation of a vehicle based on the fusion of visual odometry and SeqSLAM. The template library for this latter is created online using navigation information from the visual odometry module. That is, when a location is recognized, the corresponding information is used as an observation of the filter. The fusion is done using the EKF and the UKF, the well-known nonlinear state estimation methods, to assess the superior alternative. The algorithm is evaluated using the KITTI dataset and the results show the reduction of the navigation errors by loop-closure detection. The overall position error of visual odometery with SeqSLAM is 0.22% of the trajectory, which is much smaller than the navigation errors of visual odometery alone 0.45%. In addition, despite the superiority of the UKF in a variety of estimation problems, our results indicate that the UKF performs as efficiently as the EKF at the expense of an additional computational overhead. This leads to the conclusion that the EKF is a better choice for fusing visual odometry and SeqSlam in a long-term navigation context.

    Sedentary behaviour (sitting) is a highly prevalent negative health behaviour, with individuals of all ages exposed to environments that promote prolonged sitting. Excessive sedentary behaviour adversely affects health in children and adults. As sedentary behaviour tracks from childhood into adulthood, the reduction of sedentary time in young people is key for the prevention of chronic diseases that result from excessive sitting in later life. The sedentary school classroom represents an ideal setting for environmental change, through the provision of sit-stand desks. Whilst the use of sit-stand desks in classrooms demonstrates positive effects in some key outcomes, evidence is currently limited by small samples and/or short intervention durations, with few studies adopting randomised controlled trial (RCT) designs. This paper describes the protocol of a pilot cluster RCT of a sit-stand desk intervention in primary school classrooms. A two-arm pilot cluster RCT will be conducted in eight primary schools (four intervention, four control) with at least 120 year 5 children (aged 9-10 years). Sit-stand desks will replace six standard desks in the intervention classrooms. Teachers will be encouraged to ensure all pupils are exposed to the sit-stand desks for at least 1 h/day on average using a rotation system. Schools assigned to the control arm will continue with their usual practice, no environmental changes will be made to their classrooms. Measurements will be taken at baseline, before randomisation, and at the end of the schools' academic year. In this study, the primary outcomes of interest will be school and participant recruitment and attrition, acceptability of the intervention, and acceptability and compliance to the proposed outcome measures (including activPAL-measured school-time and school-day sitting, accelerometer-measured physical activity, adiposity, blood pressure, cognitive function, academic progress, engagement, and behaviour) for inclusion in a

    1990-01-01

    This paper presents a solution to the positional estimation problem of an autonomous land vehicle navigating in an unstructured mountainous terrain. A Digital Elevation Map (DEM) of the area in which the robot is to navigate is assumed to be given. It is also assumed that the robot is equipped with a camera that can be panned and tilted, and a device to measure the elevation of the robot above the ground surface. No recognizable landmarks are assumed to be present in the environment in which the robot is to navigate. The solution presented makes use of the DEM information, and structures the problem as a heuristic search in the DEM for the possible robot location. The shape and position of the horizon line in the image plane and the known camera geometry of the perspective projection are used as parameters to search the DEM. Various heuristics drawn from the geometric constraints are used to prune the search space significantly. The algorithm is made robust to errors in the imaging process by accounting for the worst care errors. The approach is tested using DEM data of areas in Colorado and Texas. The method is suitable for use in outdoor mobile robots and planetary rovers.

  11. Millimetre Level Accuracy GNSS Positioning with the Blind Adaptive Beamforming Method in Interference Environments

    Directory of Open Access Journals (Sweden)

    2016-10-01

    Full Text Available The use of antenna arrays in Global Navigation Satellite System (GNSS applications is gaining significant attention due to its superior capability to suppress both narrowband and wideband interference. However, the phase distortions resulting from array processing may limit the applicability of these methods for high precision applications using carrier phase based positioning techniques. This paper studies the phase distortions occurring with the adaptive blind beamforming method in which satellite angle of arrival (AoA information is not employed in the optimization problem. To cater to non-stationary interference scenarios, the array weights of the adaptive beamformer are continuously updated. The effects of these continuous updates on the tracking parameters of a GNSS receiver are analyzed. The second part of this paper focuses on reducing the phase distortions during the blind beamforming process in order to allow the receiver to perform carrier phase based positioning by applying a constraint on the structure of the array configuration and by compensating the array uncertainties. Limitations of the previous methods are studied and a new method is proposed that keeps the simplicity of the blind beamformer structure and, at the same time, reduces tracking degradations while achieving millimetre level positioning accuracy in interference environments. To verify the applicability of the proposed method and analyze the degradations, array signals corresponding to the GPS L1 band are generated using a combination of hardware and software simulators. Furthermore, the amount of degradation and performance of the proposed method under different conditions are evaluated based on Monte Carlo simulations.

  12. Integration of the Shuttle RMS/CBM Positioning Virtual Environment Simulation

    Dumas, Joseph D.

    1996-01-01

    Constructing the International Space Station, or other structures, in space presents a number of problems. In particular, payload restrictions for the Space Shuttle and other launch mechanisms prohibit assembly of large space-based structures on Earth. Instead, a number of smaller modules must be boosted into orbit separately and then assembled to form the final structure. The assembly process is difficult, as docking interfaces such as Common Berthing Mechanisms (CBMS) must be precisely positioned relative to each other to be within the "capture envelope" (approximately +/- 1 inch and +/- 0.3 degrees from the nominal position) and attach properly. In the case of the Space Station, the docking mechanisms are to be positioned robotically by an astronaut using the 55-foot-long Remote Manipulator System (RMS) robot arm. Unfortunately, direct visual or video observation of the placement process is difficult or impossible in many scenarios. One method that has been tested for aligning the CBMs uses a boresighted camera mounted on one CBM to view a standard target on the opposing CBM. While this method might be sufficient to achieve proper positioning with considerable effort, it does not provide a high level of confidence that the mechanisms have been placed within capture range of each other. It also does nothing to address the risk of inadvertent contact between the CBMS, which could result in RMS control software errors. In general, constraining the operator to a single viewpoint with few, if any, depth cues makes the task much more difficult than it would be if the target could be viewed in three-dimensional space from various viewpoints. The actual work area could be viewed by an astronaut during EVA; however, it would be extremely impractical to have an astronaut control the RMS while spacewalking. On the other hand, a view of the RMS and CBMs to be positioned in a virtual environment aboard the Space Shuttle orbiter or Space Station could provide similar benefits

The data were analysed to evaluate the reliability and validity of the new instrument, which assessed six dimensions of the classroom learning environment, namely, Working with Ideas, Personal Relevance, Collaboration, Critical Voice, Uncertainty in Science and Respect for Difference. Two dimensions were developed specifically for the present study in order to contextualise the questionnaire to the requirements of the new South African curriculum (namely, Metacognition and Respect for Difference). In the qualitative data collection phase, two case studies were used to investigate whether profiles of class mean scores on the new instrument could provide an accurate and "trustworthy" description of the learning environment of individual science classes. The study makes significant contributions to the field of learning environments in that it is one of the first major studies of its kind in South Africa with a focus on social constructivism and because the instrument developed captures important aspects of the learning environment associated with social constructivism.

  6. An Approach for High-precision Stand-alone Positioning in a Dynamic Environment

    Science.gov (United States)

    Halis Saka, M.; Metin Alkan, Reha; Ozpercin, Alişir

    2015-04-01

    In this study, an algorithm is developed for precise positioning in dynamic environment utilizing a single geodetic GNSS receiver using carrier phase data. In this method, users should start the measurement on a known point near the project area for a couple of seconds making use of a single dual-frequency geodetic-grade receiver. The technique employs iono-free carrier phase observations with precise products. The equation of the algorithm is given below; Sm(t(i+1))=SC(ti)+[ΦIF (t(i+1) )-ΦIF (ti)] where, Sm(t(i+1)) is the phase-range between satellites and the receiver, SC(ti) is the initial range computed from the initial known point coordinates and the satellite coordinates and ΦIF is the ionosphere-free phase measurement (in meters). Tropospheric path delays are modelled using the standard tropospheric model. To accomplish the process, an in-house program was coded and some functions were adopted from Easy-Suite available at http://kom.aau.dk/~borre/easy. In order to assess the performance of the introduced algorithm in a dynamic environment, a dataset from a kinematic test measurement was used. The data were collected from a kinematic test measurement in Istanbul, Turkey. In the test measurement, a geodetic dual-frequency GNSS receiver, Ashtech Z-Xtreme, was set up on a known point on the shore and a couple of epochs were recorded for initialization. The receiver was then moved to a vessel and data were collected for approximately 2.5 hours and the measurement was finalized on a known point on the shore. While the kinematic measurement on the vessel were carried out, another GNSS receiver was set up on a geodetic point with known coordinates on the shore and data were collected in static mode to calculate the reference trajectory of the vessel using differential technique. The coordinates of the vessel were calculated for each measurement epoch with the introduced method. With the purpose of obtaining more robust results, all coordinates were calculated

  10. Integrity monitoring of vehicle positioning in urban environment using RTK-GNSS, IMU and speedometer

    Science.gov (United States)

    El-Mowafy, Ahmed; Kubo, Nobuaki

    2017-05-01

    Continuous and trustworthy positioning is a critical capability for advanced driver assistance systems (ADAS). To achieve continuous positioning, methods such as global navigation satellite systems real-time kinematic (RTK), Doppler-based positioning, and positioning using low-cost inertial measurement unit (IMU) with car speedometer data are combined in this study. To ensure reliable positioning, the system should have integrity monitoring above a certain level, such as 99%. Achieving this level when combining different types of measurements that have different characteristics and different types of errors is a challenge. In this study, a novel integrity monitoring approach is presented for the proposed integrated system. A threat model of the measurements of the system components is discussed, which includes both the nominal performance and possible fault modes. A new protection level is presented to bound the maximum directional position error. The proposed approach was evaluated through a kinematic test in an urban area in Japan with a focus on horizontal positioning. Test results show that by integrating RTK, Doppler with IMU/speedometer, 100% positioning availability was achieved. The integrity monitoring availability was assessed and found to meet the target value where the position errors were bounded by the protection level, which was also less than an alert level, indicating the effectiveness of the proposed approach.

    2013-01-01

    Verbal abuse in the workplace is experienced by registered nurses (RNs) worldwide; physicians are one of the main sources of verbal abuse. To examine the relationship between levels of physician verbal abuse of early-career RNs and demographics, work attributes, and perceived work environment. Fourth wave of a mailed national panel survey of early career RNs begun in 2006. RNs' perception of verbal abuse by physicians was significantly associated with poor workgroup cohesion, lower supervisory and mentor support, greater quantitative workload, organizational constraints, and nurse-colleague verbal abuse, as well as RNs' lower job satisfaction, organizational commitment, and intent to stay. RNs working in unfavorable work environments experience more physician abuse and have less favorable work attitudes. Causality is unclear: do poor working conditions create an environment in which physicians are more likely to be abusive, or does verbal abuse by physicians create an unfavorable work environment?

  15. Smartphone-Based Indoor Integrated WiFi/MEMS Positioning Algorithm in a Multi-Floor Environment

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available Indoor positioning in a multi-floor environment by using a smartphone is considered in this paper. The positioning accuracy and robustness of WiFi fingerprinting-based positioning are limited due to the unexpected variation of WiFi measurements between floors. On this basis, we propose a novel smartphone-based integrated WiFi/MEMS positioning algorithm based on the robust extended Kalman filter (EKF. The proposed algorithm first relies on the gait detection approach and quaternion algorithm to estimate the velocity and heading angles of the target. Second, the velocity and heading angles, together with the results of WiFi fingerprinting-based positioning, are considered as the input of the robust EKF for the sake of conducting two-dimensional (2D positioning. Third, the proposed algorithm calculates the height of the target by using the real-time recorded barometer and geographic data. Finally, the experimental results show that the proposed algorithm achieves the positioning accuracy with root mean square errors (RMSEs less than 1 m in an actual multi-floor environment.

    Shatté, Andrew; Perlman, Adam; Smith, Brad; Lynch, Wendy D

    2017-02-01

    To examine whether resilience has a protective effect in difficult work environments. A survey of 2063 individuals measured individual resilience, stress, burnout, sleep problems, likelihood of depression, job satisfaction, intent to quit, absences, and productivity. It also measured work characteristics: job demands, job influence, and social support. Multivariate and logistic regression models examined the main effects and interactions of resilience and job characteristics. High strain work environments (high demand, low influence, and low support) have an unfavorable effect on all outcomes. Resilience has a protective effect on all outcomes. For stress, burnout, and sleep, higher resilience has a more protective effect under low-strain conditions. For depression, absence and productivity, resilience has a more protective effect when job strain is high. Workers with high resilience have better outcomes in difficult work environments.

  1. Why classroom climate matters for children high in anxious solitude: A study of differential susceptibility.

    Science.gov (United States)

    Hughes, Kathleen; Coplan, Robert J

    2018-03-01

    The goal of the current study was to examine the complex links among anxious solitude, classroom climate, engagement, achievement, and gender. In particular, drawing upon the differential susceptibility hypothesis (Belsky, 1997), we investigated if children high in anxious solitude were particularly sensitive and responsive to the classroom environment. Participants were N = 712 children in Grade 3, drawn from the National Institute of Child and Human Development (NICHD) Study of Early Child Care and Youth Development data set. Classroom climate and engagement were assessed using the Classroom Observation Scale (NICHD, 1998). Teachers completed the Teacher Report Form (Achenbach, 1991) as a measure of anxious solitude and the Academic Rating Scale (NICHD, 2010) as a measure of achievement. Hypothesized associations among variables were tested by way of a moderated-mediation model. Among the results, engagement was found to mediate the relation between classroom climate and achievement. In addition, anxious solitude and gender were found to moderate the relation between classroom climate and engagement. Support for the differential susceptibility hypothesis was found, suggesting that children high in anxious solitude may be more reactive (both positively and negatively) to elements of the classroom environment. In addition, gender differences were observed, indicating that boys may be more responsive to the classroom environment as compared with girls. Implications for future research and educational policies are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    To assess perceptions of educational environment of students from 22 Brazilian medical schools and to study the association between these perceptions and quality of life (QoL) measures. The authors performed a multicenter study (August 2011 to August 2012), examining students' views both of (1) educational environment using the Dundee Ready Education Environment Measure (DREEM) and (2) QoL using the World Health Organization Quality of Life Assessment, abbreviated version (WHOQOL-BREF). They also examined students' self-assessment of their overall QoL and medical-school-related QoL (MSQoL). The authors classified participants' perceptions into four quartiles according to DREEM total score, overall QoL, and MSQoL. Of 1,650 randomly selected students, 1,350 (81.8%) completed the study. The mean total DREEM score was 119.4 (standard deviation = 27.1). Higher total DREEM scores were associated with higher overall QoL and MSQoL scores (P student QoL.

  5. Protection of the environment. How to position radioprotection in an ecological risk assessment perspective

    International Nuclear Information System (INIS)

    Brechignac, Francois

    2003-01-01

    The development of a system capable of ensuring adequate protection of the environment from the harmful effects of ionising radiation is at present particularly debated. This need comes both from a restrictive consideration of the environment in the so far existing system for human radioprotection, and the planetary-wide growing concerns about man's technogenic influence on his environment which have yielded 'sustainability' and 'precaution' as guiding principles for environmental protection. Whilst evolving from the field of human radioprotection, the radioprotection of the environment needs to be discussed in a wider perspective, with particular emphasis on the most advanced concepts which emerge from the efforts to deriving improved approaches to Ecological Risk Assessment. For the sake of protection, the environment is traditionally addressed through its biota since these are the sensitive components of ecosystems. Similarities between man and biotas reflect the ubiquitous mechanistic effects of radiation on life which disrupt molecules. However, important differences also arise in a number of perspectives, from the large spectrum of different species of biotas to their hierarchical self-organisation as interacting populations within ecosystems. Altogether, these aspects are prone to promote complex arrays of different responses to stress which lie beyond the scope of human radioprotection due to its focus on individuals of a single species. By means of selected illustrations, this paper reviews and discusses the current challenges faced in proper identification of measurable effect endpoints (stochastic/deterministic, individual/population- or ecosystem-relevant), dose limits in chronic exposure (or levels of concern), and their consideration according to radiation type (RBE) and interactions with other contaminants (synergies/antagonisms) which represent critical gaps in knowledge. The system of human radioprotection has conceptually been targeted at limiting

    Collaboration is a complex phenomenon, where intersubjective dynamics can greatly affect the productive outcome. Evaluation of collaboration is thus of great interest, and can potentially help achieve better outcomes and performance. However, quantitative measurement of collaboration is difficult, because much of the interaction occurs in the intersubjective space between collaborators. Manual observation and/or self-reports are subjective, laborious, and have a poor temporal resolution. The problem is compounded in natural settings where task-activity and response-compliance cannot be controlled. Physiological signals provide an objective mean to quantify intersubjective rapport (as synchrony), but require novel methods to support broad deployment outside the lab. We studied 28 student dyads during a self-directed classroom pair-programming exercise. Sympathetic and parasympathetic nervous system activation was measured during task performance using electrodermal activity and electrocardiography. Results suggest that (a) we can isolate cognitive processes (mental workload) from confounding environmental effects, and (b) electrodermal signals show role-specific but correlated affective response profiles. We demonstrate the potential for social physiological compliance to quantify pair-work in natural settings, with no experimental manipulation of participants required. Our objective approach has a high temporal resolution, is scalable, non-intrusive, and robust.

    Mitchell, Mary M; Bradshaw, Catherine P

    2013-10-01

    There is growing emphasis on the use of positive behavior supports rather than exclusionary discipline strategies to promote a positive classroom environment. Yet, there has been limited research examining the association between these two different approaches to classroom management and students' perceptions of school climate. Data from 1902 students within 93 classrooms that were nested within 37 elementary schools were examined using multilevel structural equation modeling procedures to investigate the association between two different classroom management strategies (i.e., exclusionary discipline strategies and the use of positive behavior supports) and student ratings of school climate (i.e., fairness, order and discipline, student-teacher relationship, and academic motivation). The analyses indicated that greater use of exclusionary discipline strategies was associated with lower order and discipline scores, whereas greater use of classroom-based positive behavior supports was associated with higher scores on order and discipline, fairness, and student-teacher relationship. These findings suggest that pre-service training and professional development activities should promote teachers' use of positive behavior support strategies and encourage reduced reliance on exclusionary discipline strategies in order to enhance the school climate and conditions for learning.

    With estimates of a 51% growth in the number of nursing assistants needed by 2016, there is a critical need to examine workplace factors that negatively contribute to the recruitment and retention of nursing assistants. Studies have shown that high demands, physical stress, and chronic workforce shortages contribute to a working environment that fosters one of the highest workforce injury rates in the United States. The aim of this study was to explore the relationship between nursing assistant injury rates and key outcomes, such as job satisfaction and turnover intent, while exploring workplace environment factors, such as injury prevention training, supervisor support, and employee engagement, that can decrease the rates of workplace injury. Data from the 2004 National Nursing Assistant Survey were used to examine the negative effects of workplace injury on nursing assistants and the workplace environment factors that are related to the rate of worker injury. Nursing assistants who experience job-related injuries have lower levels of job satisfaction, increased turnover intentions, and are less likely to recommend their facility as a place to work or seek care services. It was also found that nursing assistant injury rates are related to employee ratings of injury prevention training, supervisor support, and employee engagement. NAs with multiple injuries (>2) were 1.3-1.6 times more likely to report being injured at work than NAs who had not been injured when supervisor support, employee engagement, and training ratings were low. Evidence that health care organizations can use to better understand how workplace injuries occur and insight into ways to reduce the current staggering rate of on-the-job injuries occurring in health care workplaces were offered in this study. The findings also offer empirical support for an extension of the National Institute for Occupational Health and Safety/National Occupational Research Agenda Work Organization Framework for

    In the present study we examined how genotype-environment correlation processes differ as a function of adolescent age. We tested whether adolescent age moderates genetic and environmental influences on positivity and negativity in mother-adolescent and father-adolescent relationships using parallel samples of twin parents from the Twin and Offspring Study in Sweden and twin/sibling adolescents from the Nonshared Environment in Adolescent Development Study. We inferred differences in the role of passive and non-passive genotype-environment correlation based on biometric moderation findings. Findings indicated that non-passive rGE played a stronger role for positivity in mother- and father- adolescent relationships in families with older adolescents than families with younger adolescents, and that passive rGE played a stronger role for positivity in the mother-adolescent relationship in families with younger adolescents than in families with older adolescents. Implications of these findings for the timing and targeting of interventions on family relationships are discussed. PMID:25924807

    The purpose of this research was to examine relationships between eating behaviors and the cognitive environment in primarily Hispanic low-income households with young children receiving WIC benefits in Los Angeles County. Survey data were collected from 3645 low-income families with children age 12-65 mo in Los Angeles County. Eating behaviors were measured through questions about fruit, vegetable, milk, soft drink, and fast food intake. The cognitive environment was evaluated through questions on the home literacy environment (HLE), reading frequency, and preschool enrollment. All healthy eating behaviors measured were significantly and positively associated with reading frequency and HLE scores after adjustment for confounders. HLE and reading frequency scores were 18% and 14% higher, respectively, in children eating two or more servings of fruit per day and 12% and 9% higher, respectively, in children eating three or more servings of vegetables per day. Preschool enrollment was not significantly associated with any eating behavior. Outcomes varied by language-ethnic groups and child sex. Results suggest that healthy eating behaviors are positively associated with stronger cognitive environments in low-income Hispanic families with young children. Interventions to prevent childhood obesity in this group may therefore benefit from including a home literacy component. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Sexual harassment has been widely studied in the workforce, but the factors that contribute to hostile educational environments for women have received less attention. The present study focuses on male dominance, gender harassment, gender threats, masculinity, and their influences on creating a hostile environment for women in academia. One hundred and forty-two male participants from a private university in the Southwestern United States self-reported their masculinity, completed a group task with a female confederate leader serving as a gender threat in half the conditions, and had their subsequent affect, perceptions of leadership effectiveness, and behavioral aggression measured. Men from male-dominated majors and men who had received a gender threat did not differ from men from gender-equivalent majors and men who had not received a gender threat on affect, perceptions of leadership effectiveness, or behavioral aggression (ps > 0.201, ηp2s ≤ 0.007. However, post-hoc analyses revealed that as masculinity increased among men from male-dominated majors under gender threat, they became significantly more behaviorally aggressive (b = 5.92, p = 0.003 and perceived their female leader as less effective (b = −0.83, p = 0.076. Implications and suggestions for future research are discussed.

    It is important to understand levels and social inequalities in childhood overweight within and between countries. This study examined prevalence and social inequality in adolescent overweight in 35 countries, and associations with macroeconomic factors. International cross-sectional survey in national samples of schools. A total of 11-, 13- and 15-year-olds from 35 countries in Europe and North America in 2001-2002 (N=162 305). The main outcome measure was overweight based on self-reported height and weight (body mass index cut-points corresponding to body mass index of 25 kg/m(2) at the age of 18 years). Measures included family and school affluence (within countries), and average country income and economic inequality (between countries). There were large variations in adolescent overweight, from 3.5% in Lithuanian girls to 31.7% in boys from Malta. Prevalence of overweight was higher among children from less affluent families in 21 of 24 Western and 5 of 10 Central European countries. However, children from more affluent families were at higher risk of overweight in Croatia, Estonia and Latvia. In Poland, Lithuania, Macedonia and Finland, girls from less affluent families were more overweight whereas the opposite was found for boys. Average country income was associated with prevalence and inequality in overweight when considering all countries together. However, economic inequality as measured by the Gini coefficient was differentially associated with prevalence and socioeconomic inequality in overweight among the 23-high income and 10-middle income countries, with a positive relationship among the high income countries and a negative association among the middle income countries. The direction and magnitude of social inequality in adolescent overweight shows large international variation, with negative social gradients in most countries, but positive social gradients, especially for boys, in some Central European countries.

    2016-08-01

    Eating behaviors among a large population of children are studied as a dynamic process driven by nonlinear interactions in the sociocultural school environment. The impact of food association learning on diet dynamics, inspired by a pilot study conducted among Arizona children in Pre-Kindergarten to 8th grades, is used to build simple population-level learning models. Qualitatively, mathematical studies are used to highlight the possible ramifications of instruction, learning in nutrition, and health at the community level. Model results suggest that nutrition education programs at the population-level have minimal impact on improving eating behaviors, findings that agree with prior field studies. Hence, the incorporation of food association learning may be a better strategy for creating resilient communities of healthy and non-healthy eaters. A Ratatouille effect can be observed when food association learners become food preference learners, a potential sustainable behavioral change, which in turn, may impact the overall distribution of healthy eaters. In short, this work evaluates the effectiveness of population-level intervention strategies and the importance of institutionalizing nutrition programs that factor in economical, social, cultural, and environmental elements that mesh well with the norms and values in the community.

    Directory of Open Access Journals (Sweden)

    Tomoki Saito

    2016-04-01

    Full Text Available In this article, the authors address STEM pedagogies that relate to “integration” issues and to their implementation. Referring to past discussions on transdisciplinary teaching and learning (“transdisciplinarity”, the authors claim that STEM integration might lead to synergy between each of four disciplines, and the interaction of those learnings might have mutual benefits as well as disadvantages. Hence, although educators often find it difficult to leave discrete disciplines in which they studied, learning in an integrated environment that focuses on student-centered learning, could or should differ from teaching in traditional classes. Learning in the STEM Integrated Learning Environment has certain features: 1 learning is not necessarily included in and assessed by disciplines as in traditional classes; 2 learning within and across networks of learners has relationships beyond STEM disciplines; and 3 thus, the environment would be structured by vectors of those relationships. If so, teachers are expected to prepare for interactions among STEM areas of learning.

    We prospectively studied the difference in detection rates of multi-resistant Gram-positive and multi-resistant Gram-negative bacteria in the inanimate environment of patients harbouring these organisms. Up to 20 different locations around 190 patients were surveyed. Fifty-four patients were infected or colonized with methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant enterococci (VRE) and 136 with multi-resistant Gram-negative bacteria. The environmental detection rate for MRSA or VRE was 24.7% (174/705 samples) compared with 4.9% (89/1827 samples) for multi-resistant Gram-negative bacteria (PGram-positive bacteria were isolated more frequently than Gram-negatives from the hands of patients (PGram-positive and Gram-negative isolates. Our results suggest that the inanimate environment serves as a secondary source for MRSA and VRE, but less so for Gram-negative bacteria. Thus, strict contact isolation in a single room with complete barrier precautions is recommended for MRSA or VRE; however, for multi-resistant Gram-negative bacteria, contact isolation with barrier precautions for close contact but without a single room seems sufficient. This benefits not only the patients, but also the hospital by removing some of the strain placed on already over-stretched resources.

    Understanding electronic dynamics on material surfaces is fundamentally important for applications including nanoelectronics, inhomogeneous catalysis, and photovoltaics. Practical approaches based on time-dependent density functional theory for open systems have been developed to characterize the dissipative dynamics of electrons in bulk materials. The accuracy and reliability of such approaches depend critically on how the electronic structure and memory effects of surrounding material environment are accounted for. In this work, we develop a novel squared-Lorentzian decomposition scheme, which preserves the positive semi-definiteness of the environment spectral matrix. The resulting electronic dynamics is guaranteed to be both accurate and convergent even in the long-time limit. The long-time stability of electronic dynamics simulation is thus greatly improved within the current decomposition scheme. The validity and usefulness of our new approach are exemplified via two prototypical model systems: quasi-one-dimensional atomic chains and two-dimensional bilayer graphene

  9. The Role of Perception in the Typology of Geminate Consonants: Effects of Manner of Articulation, Segmental Environment, Position, and Stress.

    2018-03-01

    The present study seeks to answer the question of whether consonant duration is perceived differently across consonants of different manners of articulation and in different contextual environments and whether such differences may be related to the typology of geminates. The results of the cross-linguistic identification experiment suggest higher perceptual acuity in labeling short and long consonants in sonorants than in obstruents. Duration categories were also more consistently and clearly labeled in the intervocalic than in the preconsonantal environment, in the word-initial than in the word-final position, and after stressed vowels than between unstressed vowels. These perceptual asymmetries are in line with some typological tendencies, such as the cross-linguistic preference for intervocalic and post-stress geminates, but contradict other proposed cross-linguistic patterns, such as the preference for obstruent geminates and the abundance of word-final geminates.

    predictable and provides base-load electricity with high reliability to the end-user. It is not subject to variations in fuel availability as uranium is largely available from diverse politically stable countries that secure its supply. Nuclear power is therefore a key asset for energy security and independence. Nuclear energy is part of the solution. The European Nuclear Society Young Generation Network believes that nuclear is part of the solution. Current nuclear power plants operate safely with negligible CO 2 emissions and provide energy to millions of people. Existing and future nuclear reactors will help humanity to overcome energy challenges whilst respecting the environment. Research is still on-going for more efficient use of nuclear fuel and the transmutation of high activity long-term waste. These objectives are carried out by the promising implementation of Generation IV of nuclear power plants with commercial prospects by 2030-2040. Research on nuclear fusion such as the ITER project aims to provide an almost inexhaustible source of energy while suppressing the issue of handling long-lived radioactive waste. This is the future of the nuclear industry. Our belief is that fighting climate change cannot discard, on ideological background and judgment, such promising technologies. It is our duty to inform the public in an objective and scientific way of the benefits of nuclear power. COP21 is a unique opportunity to internationally develop a low-carbon society in which nuclear power will have a key role to play. (authors)

    Full Text Available Inclusive education in Brazil has been widely discussed in all areas of the educational. The inclusion of pupils with special educational needs (SEN in mainstream schools is increasingly frequent, though still many aspects need to be rethought. This work aimed at checking how the subjects with SEN in Early Stimulation age, from zero to three years and 11 months are included into the regular classroom environment, at Nursery Schools, of an average municipality - Vale dos Sinos. This work involved a cross-sectional survey of quantitative and descriptive statistics. The data collection was carried out directly from a structured questionnaire with open and closed questions, directed to all principals of the thirteen Nursery Schools in the referred municipality. From the thirteen schools of the municipality only one did not take part of the research since there was no enrollment of children with special needs there, totalizing 46 children in processes of educational inclusion. From those, twelve children (26.8% were benefited with an Early Stimulation service maintained by the Association of Parents and Friends of Exceptional Children of that referred municipality, Thirty children (65,2% enrolled in school at the initiative of his own family e four children (8% by intervention of the Wakefield council. In this sense, we believe that the professionals of the Early Stimulation have the responsibility of promoting and conveying its importance and, mainly, the benefits of Early Stimulation for the whole development of individuals, as well as its contribution to a process of inclusive education.

  14. a Statistical Analysis on the System Performance of a Bluetooth Low Energy Indoor Positioning System in a 3d Environment

    Since GPS tends to fail for indoor positioning purposes, alternative methods like indoor positioning systems (IPS) based on Bluetooth low energy (BLE) are developing rapidly. Generally, IPS are deployed in environments covered with obstacles such as furniture, walls, people and electronics influencing the signal propagation. The major factor influencing the system performance and to acquire optimal positioning results is the geometry of the beacons. The geometry of the beacons is limited to the available infrastructure that can be deployed (number of beacons, basestations and tags), which leads to the following challenge: Given a limited number of beacons, where should they be placed in a specified indoor environment, such that the geometry contributes to optimal positioning results? This paper aims to propose a statistical model that is able to select the optimal configuration that satisfies the user requirements in terms of precision. The model requires the definition of a chosen 3D space (in our case 7 × 10 × 6 meter), number of beacons, possible user tag locations and a performance threshold (e.g. required precision). For any given set of beacon and receiver locations, the precision, internal- and external reliability can be determined on forehand. As validation, the modeled precision has been compared with observed precision results. The measurements have been performed with an IPS of BlooLoc at a chosen set of user tag locations for a given geometric configuration. Eventually, the model is able to select the optimal geometric configuration out of millions of possible configurations based on a performance threshold (e.g. required precision).

    The appeal of online learning has increased dramatically among nurses who are pursuing higher-education opportunities. However, online learning has created potential avenues for uncivil behaviors that can affect student satisfaction, performance, and retention. This is the second of 2 articles detailing a study to empirically measure nursing faculty and student perceptions of an online learning environment (OLE). Part 1, in the July/August 2012 issue, described the quantitative results including the types and frequency of uncivil behaviors and the extent to which they are perceived to be a problem in online courses. In this portion of the study, the authors discuss the qualitative findings, including the challenges and advantages of the OLE, specific ways to foster civility, and strategies to promote student success and retention.

    Vancomycin-resistant enterococci [VRE] have been isolated from municipal, hospital and agricultural wastewater, recreational beaches, wild animals, birds and food animals around the world. In this study, American crows (Corvus brachyrhynchos) from sewage treatment plants (WWTP), dairy farms, and a large roost in a restored wetland with corresponding environmental samples were cultured for VRE. A total of 245 samples [156 crows, 89 environmental] were collected and screened for acquired vanA, vanB and/or intrinsic vanC1 genes. Samples were enriched overnight in BHI supplemented with 20μg/mL aztreonam, 4μg/mL vancomycin and plated on m-Enterococcus agar media supplemented with 6μg/mL vancomycin. Selected colonies were grown on BHI media supplemented with 18μg/mL vancomycin. Of these, 24.5% of the crow and 55% the environmental/cow samples were VRE positive as defined by Enterococcus spp. able to grow on media supplemented with 18μg/mL vancomycin. A total of 122 VRE isolates, 43 crow and 79 environmental isolates were screened, identified to species level using 16S sequencing and further characterized. Four vanA E. faecium and multiple vanC1 E. gallinarum were identified from crows isolated from three sites. E. faecium vanA and E. gallinarum vanC1 along with other Enterococcus spp. carrying vanA, vanB, vanC1 were isolated from three environments. All enterococci were multidrug resistant. Crows were more likely to carry vanA E. faecium than either the cow feces or wetland waters/soils. Comparing E. gallinarum vanC1 from crows and their environment would be useful in determining whether crows share VRE strains with their environment. Copyright © 2016 Elsevier B.V.

Data was derived from the German National Educational Panel Study (NEPS) using sixth grade school-aged children (n = 4,764, 483 classes). Class climate includes indicators of teachers' care and monitoring, demands, interaction, autonomy, as well as school-aged children's attitudes towards schoolwork at the class- and individual-level. Results showed that individual perceived class climate in terms of teachers' care and monitoring and autonomy was positively related to life satisfaction, whereas school-related demands were related to lower life satisfaction. Besides teachers' care and monitoring at class-level, indicators of class climate were not associated with school-aged children's life satisfaction, while the individual perceived class climate is more important for life satisfaction.

    Full Text Available This paper presents the first very positive findings from an empirical study about the effectiveness of the use of a Kinect learning game for children with gross motor skills problems and motor impairments. This game follows the principles of a newly presented approach, called Kinems, which advocates that special educators and therapists should use learning games that via embodied touchless interaction – thanks to the Microsoft Kinect camera- children with dyspraxia and other related disorders such as autism, Asperger's Syndrome, and Attention Deficit Disorder, can improve related skills. Several Kinems games have been proposed (http://www.kinems.com. These games are innovative and are played with hand and body gestures. Kinems suggests that games should be highly configurable so that a teacher can modify the settings (e.g. difficult level, time settings, etc. for the individual needs of each child. Also, a teacher should have access to kinetic and learning analytics of the child’s interaction progress and achievements should be safely stored and vividly presented.

  6. Teaching Horror Literature in a Multicultural Classroom

    Directory of Open Access Journals (Sweden)

    Ljubica Matek

    2015-06-01

    Full Text Available As a genre, horror tends to be marginalized in literature classes because it is often mistakenly perceived to be inappropriate for the classroom environment due to the intensive emotional effects that the genre’s typical macabre motifs and topics may produce in the reader. However, this paper argues that, for two reasons, horror texts represent a valid and important addition to a literary syllabus. First, they typically have a positive impact on the students’ increased interest in reading, which is, in the pedagogical and scholarly sense, a desirable activity. Second, they tend to contribute significantly to the development of empathy with and tolerance for others, which is an especially valuable learning outcome in a multicultural classroom characterized by implied intercultural communication.

    2015-01-01

    One of the novel ideas in teaching that heavily relies on current technology is the “flipped classroom” approach. In a flipped classroom the traditional lecture and homework sessions are inverted. Students are provided with online material in order to gain necessary knowledge before class, while...... class time is devoted to clarifications and application of this knowledge. The hypothesis is that there could be deep and creative discussions when teacher and students physically meet. This paper presents design considerations for flipped classrooms, and discusses how Moodle can facilitate...... with a discussion of the opportunities and challenges when implementing the flipped model in a virtual learning environment (VLE) like Moodle....

    Fuller, C. A.

    1985-01-01

    The influence of chronic centrifugation upon the homestatic regulation of the circadian timekeeping system was examined. The interactions of body temperature regulation and the behavioral state of arousal were studied by evaluating the influence of cephalic fluid shifts induced by lower body positive air pressure (LBPP), upon these systems. The small diurnal squirrel monkey (Saimiri sciureus) was used as the non-human primate model. Results show that the circadian timekeeping system of these primates is functional in the hyperdynamic environment, however, some of its components appear to be regulated at different homeostatic levels. The LBPP resulted in an approximate 0.7 C decrease in DBT (p 0.01). However, although on video some animals appeared drowsy during LBPP, sleep recording revealed no significant changes in state of arousal. Thus, the physiological mechanisms underlying this lowering of body temperature can be independent of the arousal state.

    Perception of speech is crucial in school where speech is the main mode of communication. The aim of the study was to evaluate whether a web based approach including listening tests and questionnaires could be used as a screening tool for poor classroom acoustics. The prime focus was the relation between pupils' comprehension of speech, the classroom acoustics and their description of the acoustic qualities of the classroom. In total, 1106 pupils aged 13-19, from 59 classes and 38 schools in Sweden participated in a listening study using Hagerman's sentences administered via Internet. Four listening conditions were applied: high and low background noise level and positions close and far away from the loudspeaker. The pupils described the acoustic quality of the classroom and teachers provided information on the physical features of the classroom using questionnaires. In 69% of the classes, at least three pupils described the sound environment as adverse and in 88% of the classes one or more pupil reported often having difficulties concentrating due to noise. The pupils' comprehension of speech was strongly influenced by the background noise level (pcomprehension. Of the pupils' descriptions of acoustic qualities, clattery significantly (pcomprehension. Clattery was furthermore associated to difficulties understanding each other, while the description noisy was associated to concentration difficulties. The majority of classrooms do not seem to have an optimal sound environment. The pupil's descriptions of acoustic qualities and listening tests can be one way of predicting sound conditions in the classroom.

    2013-10-15

    The spread of Gram-negative bacteria with plasmid-borne extended-spectrum beta-lactamases (ESBLs) has become a worldwide problem. Their prevalence is increasing, both in hospitals and in the environment. The aim of this study was to investigate the presence of ESBL-positive Enterobacteriaceae in municipal sewage and their emission to the ambient air and the river receiving effluent from wastewater treatment plant (WWTP). In the group of 455 isolated strains, up to 19.8% (90 isolates) were phenotypic ESBL-producers. They were detected in the 63 (100%) of sewage samples analyzed, 7 (33.3%) of river water and in 10 (23.8%) of air samples collected at the WWTP area. The plasmid-mediated genes encoding beta-lactams resistance were detected in almost 10% out of bacteria of the WWTP's final effluents and in above 32% out of bacteria of air at the WWTP area. It confirms that those genes are released into the environment, which might facilitate further dissemination among environmental bacteria. Moreover, genes encoding antibiotic resistance were shown to be transferrable to an Escherichia coli recipient strain, which indicates a high possibility of horizontal gene transfer among strains of different genera within the sewage and environmental samples. This study demonstrated that despite the treatment, the municipal sewage may be a reservoir of antibiotic-resistant microorganisms and plasmid-mediated antibiotic resistance genes. This may pose a public health risk, which requires future evaluation and control. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Chen, C. Y. Roger; Meliksetian, Dikran S.; Chang, Martin C.

    1996-01-01

    In this paper we discuss how classroom instruction can benefit from state-of-the-art technologies in networks, worldwide web access through Internet, multimedia, databases, and computing. Functional requirements for establishing such a high-tech classroom are identified, followed by descriptions of our current experimental implementations. The focus of the paper is on the capabilities of distributed collaboration, which supports both synchronous multimedia information sharing as well as a shared work environment for distributed teamwork and group decision making. Our ultimate goal is to achieve the concept of 'living world in a classroom' such that live and dynamic up-to-date information and material from all over the world can be integrated into classroom instruction on a real-time basis. We describe how we incorporate application developments in a geography study tool, worldwide web information retrievals, databases, and programming environments into the collaborative system.

    2018-04-03

    Much of what is formally taught in medicine is about the knowledge, skills, and behaviors required of a physician, including how to express compassion and respect for patients at the bedside. What is learned, however, includes not only admirable qualities but also behaviors and qualities that are inconsistent with ethics and professionalism. Positive role models may reinforce the character and values the profession seeks to cultivate; negative ones directly contradict classroom lessons and expectations of patients, society, and medical educators. These positive and negative lessons, which are embedded in organizational structure and culture, are the hidden curricula conveyed in medical schools, residency programs, hospitals, and clinics. This position paper from the American College of Physicians focuses on ethics, professionalism, and the hidden curriculum. It provides strategies for revealing what is hidden to foster the development of reflective and resilient lifelong learners who embody professionalism and clinicians who are, and are perceived as, positive role models. Making the hidden visible and the implicit explicit helps to create a culture reflecting medicine's core values.

    2015-07-01

    Full Text Available The use of learning technologies, especially multimedia provide varied facilities for students’ learning that are not possible with other media. Pedagogical literature has proved that individuals have different learning styles. Flipped classroom is a pedagogical approach which means that activities that have traditionally taken place inside the classroom take place outside the classroom and vice versa. Flipped classroom environment ensures that students become more active participants compared with the traditional classroom. The purpose of this paper is to fulfil the needs regarding the review of recent literature on the use of flipped classroom approach in education. The contribution of flipped classroom to education is discussed in relation to the change of students' and instructors' role. Subsequently, flipped classroom applications in various disciplines of education are illustrated. The recommendations made in the literature for design specifications that integrate flipped classrooms with technology are discussed. The paper concludes that a careful consideration of the warnings and recommendations made in the literature can help to produce effective flipped classroom environments and also this paper attempts to inform those who are thinking of using new technologies and approaches to deliver courses.

  20. The impact of single-gender classrooms on science achievement of middle school gifted girls

    Science.gov (United States)

    Ulkins, David S.

    Studies indicate a gap in science achievement and positive attitudes towards science between gifted male and female students with females performing less than the males. This study investigated the impact of a single-gender classroom environment as opposed to a mixed-gender classroom, on motivation, locus of control, self-concept, and science achievement of middle school gifted girls. The Motivated Strategies for Learning Questionnaire (MSLQ), Review of Personal Effectiveness with Locus of Control (ROPELOC), Test of Science Related Attitudes (TOSRA), and Stanford Achievement Test 10th Edition, were used to measure the dependent variables respectively. The independent-measure t test was used to compare the differences between girls in a single-gender classroom with the ones in a mixed-gender classroom. A significant difference in the external locus of control resulted for girls in the single gender classroom. However, there were no significant differences found in science achievement, motivation, and the attitudes toward science between the two groups. The implication is that a single-gender learning environment and the use of differentiated teaching strategies can help lessen the negative effects of societal stereotypes in today's classrooms. These, along with being cognizant of the differences in learning styles of girls and their male counterparts, will result in a greater level of success for gifted females in the area of science education.

    1992-01-01

    The development of the hydrocarbon resources of the North Sea has resulted in both offshore and onshore environmental repercussions, involving the existing physical attributes of the sea and seabed, the coastline and adjoining land. The social and economic repercussions of the industry were equally widespread. The dramatic and speedy impact of the exploration and exploitation of the northern North Sea resources in the early 1970s, on the physical resources of Scotland was quickly realised together with the concern that any environmental and social damage to the physical and social fabric should be kept to a minimum. To this end, a wide range of research and other activities by central and local government, and other interested agencies was undertaken to extend existing knowledge on the marine and terrestrial environments that might be affected by the oil and gas industry. The outcome of these activities is summarized in this paper. The topics covered include a survey of the marine ecosystems of the North Sea, the fishing industry, the impact of oil pollution on seabirds and fish stocks, the ecology of the Scottish coastline and the impact of the petroleum industry on a selection of particular sites.

    Mantas, E.; Remoundaki, E.; Halari, I.; Kassomenos, P.; Theodosi, C.; Hatzikioseyian, A.; Mihalopoulos, N.

    2014-09-01

    A systematic monitoring of PM2.5 was carried out during a period of three years (from February 2010 to April 2013) at an urban site, at the National Technical University of Athens campus. Two types of 24-h PM2.5 samples have been collected: 271 samples on PTFE and 116 samples on quartz filters. Daily PM2.5 concentrations were determined for both types of samples. Total sulfur, crustal origin elements and elements of a major crustal component (Al, Si, Fe, Ca, K, Mg, Ti) trace elements (Zn, Pb, Cu, Ni, P, V, Cr, Mn) and water soluble ions (Cl-, NO3-, SO42-, Na+, K+, NH4+, Ca2+, Mg2+) were determined on the PTFE samples. Organic carbon (OC), elemental carbon (EC) and water soluble ions were determined on the quartz samples. For the mass closure six components were considered: Secondary Inorganic Aerosol (SIA), Organic Matter (OM), Elemental Carbon (EC), Dust, Mineral anthropogenic component (MIN) and Sea Salt (SS). SIA and OM contributed in the mass of PM2.5 almost equally: 30-36% and 30% respectively. EC, SS and MIN accounted for 5, 4 and 3% respectively of the total PM2.5 mass. Dust accounted for about 3-5% in absence of dust transport event and reached a much higher percentage in case of dust transport event. These contributions justify at least 80% of the PM2.5 mass. Source apportionment analysis has been performed by Positive Matrix Factorization. The combination of the PMF results obtained by both data sets lead to the definition of six factors: 1. SO42-, NH4+, OC (industrial/regional sources, secondary aerosol) 2. EC, OC, K and trace metals (traffic and heating by biomass burning, locally emitted aerosol). 3. Ca, EC, OC and trace metals (urban-resuspended road dust reflecting exhaust emissions), 4. Secondary nitrates 5. Na, Cl (marine source) 6. Si, Al, Ti, Ca, Fe (Dust transported from Sahara). These factors reflect not only main sources contributions but also underline the key role of atmospheric dynamics and aerosol ageing processes in this Mediterranean

    2016-11-01

    Full Text Available The smart classroom incorporates many different types of IT hardware including tablet computers, interactive white boards, work stations and many other integrated uses of these IT technologies which are used for instructional purposes. Conducted with 40 students majoring in Communicative Arts who participated in a technology-supported learning environment, this study investigated the perceived effectiveness of technologies, learner motivation, participation and learning outcome in the smart classroom. Research findings show that the students’ perceived effectiveness of educational technologies was at a high level while their learning motivation was at a moderate level. In addition, a positive relationship was found between students’ learning outcome and participation, but motivation and perceived effectiveness of technologies in the smart classroom were not related to their learning outcome. Responses from open-ended questions can be used to support the acceptance of the new learning environment since the use of various media equipment by first time users allows for the exploration and the presentation of ideas not achieved in a traditional classroom setting. It can be concluded that learning in a technology-supported environment like the smart classroom can foster a more inquisitive approach.

    Julien, Maxime; Nun, Pierrick; Robins, Richard J; Remaud, Gérald S; Parinet, Julien; Höhener, Patrick

    2015-11-03

    Position-specific isotope effects (PSIEs) have been measured by isotope ratio monitoring (13)C nuclear magnetic resonance spectrometry during the evaporation of 10 liquids of different polarities under 4 evaporation modes (passive evaporation, air-vented evaporation, low pressure evaporation, distillation). The observed effects are used to assess the validity of the Craig-Gordon isotope model for organic liquids. For seven liquids the overall isotope effect (IE) includes a vapor-liquid contribution that is strongly position-specific in polar compounds but less so in apolar compounds and a diffusive IE that is not position-specific, except in the alcohols, ethanol and propan-1-ol. The diffusive IE is diminished under forced evaporation. The position-specific isotope pattern created by liquid-vapor IEs is manifest in five liquids, which have an air-side limitation for volatilization. For the alcohols, undefined processes in the liquid phase create additional PSIEs. Three other liquids with limitations on the liquid side have a lower, highly position-specific, bulk diffusive IE. It is concluded that evaporation of organic pollutants creates unique position-specific isotope patterns that may be used to assess the progress of remediation or natural attenuation of pollution and that the Craig-Gordon isotope model is valid for the volatilization of nonpolar organic liquids with air-side limitation of the volatilization rate.

  18. Early Adolescents' Emotional Well-Being in the Classroom: The Role of Personal and Contextual Assets.

    Oberle, Eva

    2018-02-01

    The objective was to predict early adolescents' emotional well-being from personal and contextual assets in the classroom. Emotional well-being is a key indicator of health. Aligned with the positive youth development (PYD) framework, a supportive classroom environment and positive relationships with teachers and peers were contextual assets in the present study; positive self-concept was a personal asset. The sample was 406 grade 4 to 7 public elementary school students from diverse backgrounds (mean = 11.27 years; SD = 0.89; 50% female). Data were self-, teacher-, and peer-reported. Structural equation modeling (SEM) analyses were used to evaluate model fit and identify significant pathways. SEM indicated a good model fit. Overall, 68% of variability in early adolescents' emotional well-being was explained. Positive self-concept directly predicted emotional well-being. Supportive classroom environment predicted emotional well-being directly and indirectly through increases in positive social relationships and self-concept. Positive social relationships predicted well-being only indirectly through positive self-concept. Contextual and personal assets are central for early adolescents' emotional well-being. The interrelation among assets needs to be considered when understanding, and ultimately promoting students' emotional well-being. The present findings extend previous research and inform school-based intervention and prevention programming and teacher professional development. © 2018, American School Health Association.

    Early life experiences including physical exercise, sensory stimulation, and social interaction can modulate development of the inhibitory neuronal network and modify various behaviors. In particular, alteration of parvalbumin-expressing neurons, a gamma-aminobutyric acid (GABA)ergic neuronal subpopulation, has been suggested to be associated with psychiatric disorders. Here we investigated whether rearing in enriched environment could modify the expression of parvalbumin-positive neurons in the basolateral amygdala and anxiety-like behavior. Three-week-old male rats were divided into two groups: those reared in an enriched environment (EE rats) and those reared in standard cages (SE rats). After 5 weeks of rearing, the EE rats showed decreased anxiety-like behavior in an open field than the SE rats. Under another anxiogenic situation, in a beam walking test, the EE rats more quickly traversed an elevated narrow beam. Anxiety-like behavior in the open field was significantly and negatively correlated with walking time in the beam-walking test. Immunohistochemical tests revealed that the number of parvalbumin-positive neurons significantly increased in the basolateral amygdala of the EE rats than that of the SE rats, while the number of calbindin-D28k-positive neurons did not change. These parvalbumin-positive neurons had small, rounded soma and co-expressed the glutamate decarboxylase (GAD67). Furthermore, the number of parvalbumin-positive small cells in the basolateral amygdala tended to positively correlate with emergence in the center arena of the open field and negatively correlated with walking time in the beam walking test. Rearing in the enriched environment augmented the number of parvalbumin-containing specific inhibitory neuron in the basolateral amygdala, but not that of calbindin-containing neuronal phenotype. Furthermore, the number of parvalbumin-positive small neurons in the basolateral amygdala was negatively correlated with walking time in the

    Full Text Available Unruly learners and disciplinary problems are an intractable part of every teacher’s teaching experience. It appears that, even though most schools have enacted a code of conduct to regulate learner behaviour, this does not always have the desired effect. Disciplinary problems in schools impact negatively on the teaching and learning environment as well as on teachers’ personal and professional well-being and morale. Framed within the context of a biblical worldview, this article narrates the experiences of one teacher who decided to take action towards hope. The situation in her classroom was quite desperate with learners coming to school unprepared and behaving very badly and parents being uninterested in the performance of their children at school. She realised that she could not change the learners or their parents unless she started with herself. In this context, she, as a postgraduate student under the supervision of the co-authors, embarked on an action-research project to promote positive learner behaviour. By collaborating with the learners on a set of classroom rules, engaging in reflective teaching and changing her own behaviour towards the learners, the situation in her classroom improved. Based on her experiences, this article argues that teachers should empower themselves with knowledge and a better understanding of the concept of discipline rather than viewing the classroom as a battlefield. It is important to acknowledge and show respect and appreciation for each learner in his or her own context.

    The paper develops a set membership detection methodology which is applied to the detection of abnormal positions of aircraft control surfaces. Robust and early detection of such abnormal positions is an important issue for early system reconfiguration and overall optimisation of aircraft design. In order to improve fault sensitivity while ensuring a high level of robustness, the method combines a data-driven characterisation of noise and a model-driven approach based on interval prediction. The efficiency of the proposed methodology is illustrated through simulation results obtained based on data recorded in several flight scenarios of a highly representative aircraft benchmark.

    2017-02-01

    Full Text Available Roland Bal analyzes the strategies his research group developed to deal with the interlinked dynamics of research evaluation in a multi-disciplinary institutional environment characteristic of much STS research. Scholars in such environments constantly need to navigate and negotiate the standards of evaluation, in complex choreographies of cooperation and competition with other disciplinary groups. Bal describes strategies his group has successfully used, and how these strategies have both shifted the way research quality is assessed within the department as well as changed the way his group works and publishes. In conclusion, he describes performance management systems and research practices as co-constituted and calls for a debate on which forms of evaluation infrastructures allow for better ways of doing research in STS.

    Full Text Available Introduction: Students and faculty members in the health professions classroom are expected to exhibit professional behaviors that are conducive to maintaining a positive learning environment. Aim: To assess the perception of uncivil classroom behavior among the students and the faculty members in a private dental institute in Hyderabad city, India. Materials and Methods: A cross-sectional questionnaire study was conducted among the dental students and the faculty members. The mean perceptions of uncivil classroom behavior were assessed using a self-administered questionnaire of Rowland and Srisukho containing 18 items. Results: A statistically significant difference was noted between the students and the faculty members for mean perception of uncivil classroom behavior (P = 0.002. When based on gender, no significant difference was observed among the students and the staff, but when individual items were considered, most of the male students and the faculty members perceived uncivil behaviors. Among all students, the mean perception of uncivil classroom behavior was significantly high among the undergraduates (68.17 ± 14.5 and least in postgraduates (62.67 ± 22.7, and among the faculty members, it was more among the professors (82.63 ± 4.0. Conclusion: Overall, the issue of uncivil classroom behavior remains a major concern, because 88.6% of the students agreed that they were involved in uncivil classroom behavior previously.

    Full Text Available We describe and reflect on three case studies of developing fieldwork for tertiary students of architectural history, landscape history and urban design. In each case, the potential of blended learning was explored through the use of mobile technology to explore designated sites as extensions of class-based learning. Two studies involved the development of apps that worked as guides for students to explore places of significance in Melbourne, while one study invited students to develop a design for a mobile app that could communicate the influence of urban design thinkers on a particular place in Sydney. We describe how these three exercises provide insights into the way that mobile technology, both real and imagined, can provide a conduit between classroom and field learning. Equally significant, we reflect on how the process of designing the apps became one of extended co-creation between student, tutors and teaching staff, also with consequence for learning.

  11. Do school classrooms meet the visual requirements of children and recommended vision standards?

    Directory of Open Access Journals (Sweden)

    Kalpa Negiloni

    Full Text Available Visual demands of school children tend to vary with diverse classroom environments. The study aimed to evaluate the distance and near Visual Acuity (VA demand in Indian school classrooms and their comparison with the recommended vision standards.The distance and near VA demands were assessed in 33 classrooms (grades 4 to 12 of eight schools. The VA threshold demand relied on the smallest size of distance and near visual task material and viewing distance. The logMAR equivalents of minimum VA demand at specific seating positions (desk and among different grades were evaluated. The near threshold was converted into actual near VA demand by including the acuity reserve. The existing dimensions of chalkboard and classroom, gross area in a classroom per student and class size in all the measured classrooms were compared to the government recommended standards.In 33 classrooms assessed (35±10 students per room, the average distance and near logMAR VA threshold demand was 0.31±0.17 and 0.44±0.14 respectively. The mean distance VA demand (minimum in front desk position was 0.56±0.18 logMAR. Increased distance threshold demand (logMAR range -0.06, 0.19 was noted in 7 classrooms (21%. The mean VA demand in grades 4 to 8 and grades 9 to 12 was 0.35±0.16 and 0.24±0.16 logMAR respectively and the difference was not statistically significant (p = 0.055. The distance from board to front desk was greater than the recommended standard of 2.2m in 27 classrooms (82%. The other measured parameters were noted to be different from the proposed standards in majority of the classrooms.The study suggests the inclusion of task demand assessment in school vision screening protocol to provide relevant guidance to school authorities. These findings can serve as evidence to accommodate children with mild to moderate visual impairment in the regular classrooms.

    The goal of this study was to explore relations between teacher characteristics (i.e., competence and wellbeing); social classroom relationships (i.e., teacher-child and peer interactions); and children's social, emotional, and behavioral classroom adjustment. These relations were explored at both the individual and classroom levels among 414 children with emotional and behavioral disorders placed in special education. Two models were specified. In the first model, children's classroom adjustment was regressed on social relationships and teacher characteristics. In the second model, reversed links were examined by regressing teacher characteristics on social relationships and children's adjustment. Results of model 1 showed that, at the individual level, better social and emotional adjustment of children was predicted by higher levels of teacher-child closeness and better behavioral adjustment was predicted by both positive teacher-child and peer interactions. At the classroom level, positive social relationships were predicted by higher levels of teacher competence, which in turn were associated with lower classroom levels of social problems. Higher levels of teacher wellbeing were directly associated with classroom adaptive and maladaptive child outcomes. Results of model 2 showed that, at the individual and classroom levels, only the emotional and behavioral problems of children predicted social classroom relationships. At the classroom level, teacher competence was best predicted by positive teacher-child relationships and teacher wellbeing was best predicted by classroom levels of prosocial behavior. We discuss the importance of positive teacher-child and peer interactions for children placed in special education and suggest ways of improving classroom processes by targeting teacher competence.

    2013-06-01

    Water and post-larvae samples from black tiger (Penaeus monodon) shrimp hatcheries; pond water, pond sediment and shrimp from aquaculture farms were screened for the presence of V. cholerae. A V. cholerae-duplex PCR method was developed by utilizing V. cholerae species specific sodB primers and ctxAB genes specific primers. Incidence of V. cholerae was not observed in shrimp hatchery samples but was noticed in aquaculture samples. The incidence of V. cholerae was higher in pond water (7.6%) than in pond sediment (5.2%). Shrimp head (3.6%) portion had relatively higher incidence than shrimp muscle (1.6%). All the V. cholerae isolates (n = 42) belonged to non-O1/non-O139 serogroup, of which 7% of the V. cholerae isolates were potentially cholera-toxigenic (ctx positive). All the ctx positive V. cholerae (n = 3) were isolated from the pond water. Since, cholera toxin (CT) is the major contributing factor for cholera gravis, it is proposed that the mere presence of non-O1/non-O139 V. cholerae need not be the biohazard criterion in cultured black tiger shrimp but only the presence of ctx carrying non-O1/non-O139 V. cholerae may be considered as potential public health risk.

    1987-07-01

    This report presents the results of a study of the present status of geotechnical instrumentation with respect to potential use in an underground test facility at a candidate nuclear waste repository site in salt. Programmatic factors that have a general impact on the success of underground instrumentation are discussed. Performance requirements relating to accuracy, temperature range, longevity, and capability for automation are established on the basis of criteria proposed for other rock types, perceived needs of the Site Characterization Program, and the authors' experience and judgment. Test site conditions are discussed including underground logistics, corrosion, and other factors that affect instrument reliability. The status of existing instrumentation for measuring deformation, stress, temperature, fluid pressure, acoustic emission, and other less critical parameters is presented. For each instrument not presently capable of satisfying its associated performance requirements, specific development needs and possible approaches are identified, and necessary testing is describe to a conceptual level of detail. A brief discussion of instrument considerations relating to automatic data acquisition is also included. The position of instrument development as a key activity on the critical path under current schedules for the Site Characterization Program is discussed. Annotated references and reports on site visits and meetings used as the data base in evaluating present instrument status are appended to this report. 110 refs., 14 figs., 26 tabs

    Full Text Available The flipped classroom inverts traditional teaching methods, in order to have studentsprepared for topics and techniques covered in the following meeting. This approach wasadopted in a biochemistry course taught to biology freshmen students at the University ofCampinas, using a Virtual Learning Environment called 3DClass. Before each classroomsession, a quiz was delivered covering the following topic and students were allowed totake quizzes as many times as they wanted. This approach was utilized in order to betterprepare students in classes and to perform lab experiments. Every student attempt wasrecorded in a database. Before each classroom session, the instructors were provided witha summary of the class answers, highlighting questions where students had more difficultyand the ones that scored higher. This kind of information was helpful to design activities tocover the topics where students had more difficulties. Based on the 3DClass records thestudents behaviors were mapped, such as students taking the quizzes seriously, studentsguessing, students answering a quiz until scoring 100%, students that continue answeringafter scoring 100% in order to increase their grades, students that never score 100%.However, the most relevant information 3DClass brought us was the possibility to identifystudent’s confidence in their answers, which could be observed by the analysis of theirattempts for each question. If they had made different choices each try, it would haveindicated a low confidence level, while always providing the same answer indicated ahigher confidence level, even whilst picking incorrect answers. This experiment haverevealed that students coming to the classroom better prepared reflected positively on thedeveloped activities, but the number of students taking the quizzes seriously were not asgreat as we had expected, indicating that more actions should be taken to improvestudents engagement with these activities.

    2016-10-01

    Full Text Available In recent years, due to the increase in providers of orbit and clock corrections of satellites for data evaluation in real-time and post-processing the method of Precise Point Positioning (PPP using measurements of Global Navigation Satellite System (GNSS and Web-based online positioning services have become widespread. Owing to some advantages, such as work-duration and cost-effectiveness, many of users have implemented PPP method instead of the traditional relative positioning method for several applications. On GNSS applications the quality of satellite ephemerides products used for data evaluation is a significant factor that affects the results in post-processing solutions either applying relative or PPP methods on analyses. These products, classified as ultra-rapid, rapid and final orbits, are regularly provided by several national and international organizations to the users. In this paper, the accuracy of PPP method has been studied comparing the outcomes from various online Web services using different software and satellite ephemerides products. For this purpose, three test points were established in a place with completely free satellite visibility (AC01 and on the other two places with partially (YC01 and vastly (KC01 prevention of satellite signals near and within a forest area at Campus of Davutpaşa of the Yildiz Technical University in Istanbul. At these stations, static observations have been conducted with a time span of 6 hours on 4th May 2015. The dataset collected using Topcon HiperPro receiver, a receiver for GPS and GLONASS data, was evaluated manually by means of the Bernese v5.2 (BSW and GIPSY-OASIS v6.3 (Gipsy scientific software. Moreover, the GNSS data were also proceeded using six different Web-based online services (AUSPOS, OPUS, CSRS-PPP, APPS, GAPS, Trimble-RTX with ultra-rapid, rapid and final satellite ephemerides products. For the station with free satellite visibility (AC01, the analyses of outcomes indicate a

    The brain's immune privilege has been also attributed to the lack of dendritic cells (DC) within its parenchyma and the adjacent meninges, an assumption, which implies maintenance of antigens rather than their presentation in lymphoid organs. Using mice transcribing the green fluorescent protein under the promoter of the DC marker CD11c (itgax), we identified a juxtavascular population of cells expressing this DC marker and demonstrated their origin from bone marrow and local microglia. We now phenotypically compared this population with CD11c/CD45 double-positive cells from lung, liver, and spleen in healthy mice using seven-color flow cytometry. We identified unique, site-specific expression patterns of F4/80, CD80, CD86, CX3CR1, CCR2, FLT3, CD103, and MHC-II. Furthermore, we observed the two known CD45-positive populations (CD45(high) and CD45(int) ) in the brain, whereas liver, lung, and spleen exhibited a homogeneous CD45(high) population. CD11c-positive microglia lacked MHC-II expression and CD45(high) /CD11c-positive cells from the brain have a lower percentage of MHC-II-positive cells. To test whether phenotypical differences are fixed by origin or specifically develop due to environmental factors, we transplanted brain and spleen mononuclear cells on organotypic slice cultures from brain (OHSC) and spleen (OSSC). We demonstrate that adaption and ramification of MHC-II-positive splenocytes is paralleled by down-regulation of MHC-II, whereas brain-derived mononuclear cells neither ramified nor up-regulated MHC-II in OSSCs. Thus, brain-derived mononuclear cells maintain their MHC-II-negative phenotype within the environment of an immune organ. Intraparenchymal CD11c-positive cells share immunophenotypical characteristics of DCs from other organs but remain unique for their low MHC-II expression. © 2014 Wiley Periodicals, Inc.

    Growing evidence suggests that close contact with nature brings benefits to human health and well-being, but the proposed mechanisms are still not well understood and the associations with health remain uncertain. The Positive Health Effects of the Natural Outdoor environment in Typical Populations in different regions in Europe (PHENOTYPE) project investigates the interconnections between natural outdoor environments and better human health and well-being. The PHENOTYPE project explores the proposed underlying mechanisms at work (stress reduction/restorative function, physical activity, social interaction, exposure to environmental hazards) and examines the associations with health outcomes for different population groups. It implements conventional and new innovative high-tech methods to characterise the natural environment in terms of quality and quantity. Preventive as well as therapeutic effects of contact with the natural environment are being covered. PHENOTYPE further addresses implications for land-use planning and green space management. The main innovative part of the study is the evaluation of possible short-term and long-term associations of green space and health and the possible underlying mechanisms in four different countries (each with quite a different type of green space and a different use), using the same methodology, in one research programme. This type of holistic approach has not been undertaken before. Furthermore there are technological innovations such as the use of remote sensing and smartphones in the assessment of green space. The project will produce a more robust evidence base on links between exposure to natural outdoor environment and human health and well-being, in addition to a better integration of human health needs into land-use planning and green space management in rural as well as urban areas.

    Prevention of disability in the ageing workforce is essential for sustaining economic growth in Europe. In order to provide information on entry points for preventive measures, it is important to better understand sociodemographic, socioeconomic and work-related determinants of disability in older employees. We aimed to test the hypothesis that low socioeconomic position and exposure to a stressful psychosocial work environment at baseline contribute to later disability. We further assumed that the association of socioeconomic position with disability is partly mediated by exposure to adverse working conditions. We studied longitudinal data from the first two waves of the Survey on Health, Ageing and Retirement in Europe comprising 11 European countries. Sociodemographic, socioeconomic and work-related factors (low control, effort-reward imbalance) and baseline disability of 2665 male and 2209 female employees aged between 50 and 64 years were used to predict disability 2 years later. Following the International Classification of Functioning (ICF), disability was subdivided into the components 'impairment' and 'restriction in activities and participation'. Two multilevel Poisson regressions were fitted to the data. After adjusting for baseline disability and relevant confounding variables, low socioeconomic position and chronic stress at work exerted significant effects on disability scores 2 years later. We found some support for the hypothesis that the association of socioeconomic position with disability is partly mediated by work stress. Investing in reduction of work stress and reducing social inequalities in health functioning are relevant entry points of policies that aim at maintaining work ability in early old age.

  12. Do science coaches promote inquiry-based instruction in the elementary science classroom?

    Science.gov (United States)

    Wicker, Rosemary Knight

    The South Carolina Mathematics and Science Coaching Initiative established a school-based science coaching model that was effective in improving instruction by increasing the level of inquiry-based instruction in elementary science classrooms. Classroom learning environment data from both teacher groups indicated considerable differences in the quality of inquiry instruction for those classrooms of teachers supported by a science coach. All essential features of inquiry were demonstrated more frequently and at a higher level of open-ended inquiry in classrooms with the support of a science coach than were demonstrated in classrooms without a science coach. However, from teacher observations and interviews, it was determined that elementary schoolteacher practice of having students evaluate conclusions and connect them to current scientific knowledge was often neglected. Teachers with support of a science coach reported changes in inquiry-based instruction that were statistically significant. This mixed ethnographic study also suggested that the Mathematics and Science Coaching Initiative Theory of Action for Instructional Improvement was an effective model when examining the work of science coaches. All components of effective school infrastructure were positively impacted by a variety of science coaching strategies intended to promote inquiry. Professional development for competent teachers, implementation of researched-based curriculum, and instructional materials support were areas highly impacted by the work of science coaches.

  13. Toward the virtual classroom

    The Lawrence Livermore National Laboratory (LLNL) encourages its employees to remotely attend classes given by Stanford University, University of California at Davis, and the National Technological University (NTU). To improve the quality of education for LLNL employees, we are cooperating with Stanford University in upgrading the Stanford Instructional Television Network (SITN). A dedicated high-speed communication link (Tl) between Stanford and LLNL will be used for enhanced services such as videoconferencing, real time classnotes distribution, and electronic distribution of homework assignments. The new network will also allow students to take classes from their offices with the ability to ask the professor questions via an automatically dialed telephone call. As part of this upgrade, we have also proposed a new videoconferencing based classroom environment where students taking remote classes would feel as though they are attending the live class. All paperwork would be available in near real time and students may converse normally with, and see, other remote students as though they were all in the same physical location. We call this the Virtual Classroom.'' 1 ref., 6 figs.

    1992-02-01

    A class of 9-10 year-olds (N = 12) in a British primary school were observed as it moved over a one-year period through three types of classroom environment, traditional directive, transitional negotiative and established negotiative. Each environment offered the children a differing relationship with curricular time, its control and allocation, moving from teacher-allocated time to child allocation. Pupil self-report and classroom observation indicated differences in the balance of curricular spread and allocated time on curricular subject in relation to the type of classroom organisation and who controlled classroom time. These differences were at both class and individual child level. The established negotiative environment recorded the most equitable curricular balance, traditional directive the least. While individual children responded differently within and across the three classroom environments, the established negotiative where time was under child control recorded preference for longer activity periods compared to where the teacher controlled time allocations.

    Poor conditions leading to substandard indoor air quality (IAQ) in classrooms have been frequently cited in the literature over the past two decades. However, there is limited data linking poor IAQ in the classrooms to student performance. Whereas, it is assumed that poor IAQ results in reduced attendance and learning potential, and subsequent poor student performance, validating this hypothesis presents a challenge in today's school environment. This study explores the association between student performance on standardized aptitude tests that are administered to students on a yearly basis, to classroom carbon dioxide (CO2) concentrations, which provide a surrogate of ventilation being provided to each room. Data on classroom CO2 concentrations (over a 4-5 h time span within a typical school day) were recorded in fifth grade classrooms in 54 elementary schools within a school district in the USA. Results from this preliminary study yield a significant (P classroom-level ventilation rate and test results in math. They also indicate that non-linear effects may need to be considered for better representation of the association. A larger sample size is required in order to draw more definitive conclusions. Practical Implications Future studies could focus on (1) gathering more evidence on the possible association between classroom ventilation rates and students' academic performance; (2) the linear/non-linear nature of the association; and (3) whether it is possible to detect 'no observed adverse effect level' for adequate ventilation with respect to academic performance in schools. All of this information could be used to improve guidance and take regulatory actions to ensure adequate ventilation in schools. The high prevalence of low ventilation rates, combined with the growing evidence of the positive impact that sufficient ventilation has on human performance, suggests an opportunity for improving design and management of school facilities.

  18. Emotional experiences beyond the classroom: Interactions with the social world

    2018-03-01

    Full Text Available Research into the emotional experiences of language learners and their impact upon the language-learning process remains relatively undernourished within second language education. The research available focuses primarily on emotions experienced within the classroom, rather than in the daily lives of learners within various social contexts. This article contends that the focus placed upon emotions within the relatively structured environment of the formal classroom is problematic, particularly within an ESL environment, as the target language is more frequently experienced beyond the classroom. Drawing on data collected within Australia, the study explored the emotional experiences of a small cohort of eight university-level ESL learners experienced within their various social interactions beyond the classroom with a specific focus on the emotions of hope, enjoyment and frustration. Semi-structured interviews revealed that their emotional experiences beyond the classroom were particularly intense in comparison to emotional experiences within the formal language-learning classroom.

  19. Impact of variation in the BDNF gene on social stress sensitivity and the buffering impact of positive emotions: replication and extension of a gene-environment interaction.

    A previous study reported that social stress sensitivity is moderated by the brain-derived-neurotrophic-factor(Val66Met) (BDNF rs6265) genotype. Additionally, positive emotions partially neutralize this moderating effect. The current study aimed to: (i) replicate in a new independent sample of subjects with residual depressive symptoms the moderating effect of BDNF(Val66Met) genotype on social stress sensitivity, (ii) replicate the neutralizing impact of positive emotions, (iii) extend these analyses to other variations in the BDNF gene in the new independent sample and the original sample of non-depressed individuals. Previous findings were replicated in an experience sampling method (ESM) study. Negative Affect (NA) responses to social stress were stronger in "Val/Met" carriers of BDNF(Val66Met) compared to "Val/Val" carriers. Positive emotions neutralized the moderating effect of BDNF(Val66Met) genotype on social stress sensitivity in a dose-response fashion. Finally, two of four additional BDNF SNPs (rs11030101, rs2049046) showed similar moderating effects on social stress-sensitivity across both samples. The neutralizing effect of positive emotions on the moderating effects of these two additional SNPs was found in one sample. In conclusion, ESM has important advantages in gene-environment (GxE) research and may attribute to more consistent findings in future GxE research. This study shows how the impact of BDNF genetic variation on depressive symptoms may be explained by its impact on subtle daily life responses to social stress. Further, it shows that the generation of positive affect (PA) can buffer social stress sensitivity and partially undo the genetic susceptibility. Copyright © 2014 Elsevier B.V. and ECNP.

    2003-01-01

    This exploratory investigation identifies factors that contribute to success of physical therapy services delivered in the context of the daily routines in preschool classroom settings. Ten pediatric physical therapists from rural and urban communities across North Carolina served as informants during telephone interviews. Qualitative analysis of the data led to the identification of six major themes: interactions among classroom personnel, impact of the classroom environment, individual characteristics of the child, logistical considerations, administrative policies and practices, and service delivery options. All 10 informants shared the perception that the cooperation and commitment of the teacher was essential for successful incorporation of therapy activities in classroom routines. Furthermore, the informants agreed that multiple models of service delivery were necessary to meet the individual needs of children. These results lead the authors to question the wisdom of promoting any one service delivery model as "best practice" and suggest guidelines for successful integration of physical therapy in the preschool classroom.

    Trout in the Classroom (TIC) is a conservation-oriented environmental education program for elementary, middle, and high school students. During the year each teacher tailors the program to fit his or her curricular needs. Therefore, each TIC program is unique. TIC has interdisciplinary applications in science, social studies, mathematics, language arts, fine arts, and physical education. In the program, students and teachers raise trout from fertilized eggs supplied by Virginia Department of Game and Inland Fisheries (VGIF) hatcheries, in aquariums equipped with special chillers designed to keep the water near 50 degrees F. The students make daily temperature measurements, and monitor pH, dissolved oxygen, conductivity, and ammonia levels. They record their data, plot trends, and make sure that the water quality is sufficient to support trout development. The fingerlings, which hatch in late October, are almost an inch and a half long by mid-January. And towards the end of the school year, students will release the fry into VGIF approved watersheds. TIC programs have been in place all across the country for more than 20 years, and are the result of numerous collaborations between teachers, volunteers, government agencies, and local organizations like Trout Unlimited. The programs were designed specifically for teachers who wanted to incorporate more environmental education into their curriculum. While the immediate goal of Trout in the Classroom is to increase student knowledge of water quality and cold water conservation, its long-term goal is to reconnect an increasingly urbanized population of youth to the system of streams, rivers, and watersheds that sustain them. Successful programs have helped: connect students to their local environments and their local watersheds; teach about watershed health and water quality, and; get students to care about fish and the environment. In Virginia, the TIC program is now in its 8th year. Over the past year, the program

    Rubie-Davies, Christine M

    2007-06-01

    Early research exploring teacher expectations concentrated on the dyadic classroom interactions of teachers with individual students. More recent studies have shown whole class factors to have more significance in portraying teachers' expectations. Recently teachers having high or low expectations for all their students have been identified. The aim of the current investigation was to explore whether the classroom exchanges of high- and low-expectation teachers differed substantially and might be considered a mechanism for teachers' expectations. The participants were 12 primary school teachers from eight schools who had been identified as having expectations for their students' learning that were either significantly above or below the children's achievement level. The teachers formed three groups called high-expectation, low-expectation and average-progress teachers. The participants were observed twice in the academic year during half-hour reading lessons. Two people observed each lesson, one completing a structured observation protocol and the other a running record and audiotape. In contrast to the average progress and low expectation teachers, the high-expectation teachers spent more time providing a framework for students' learning, provided their students with more feedback, questioned their students using more higher-order questions, and managed their students' behaviour more positively. There appear to be important differences in the classroom environments for the students of high-expectation, average-progress and low-expectation teachers. The differences apply to both the instructional and socioemotional environments of the classroom. Such disparities may act as mechanisms for teacher expectation effects.

  6. Changes in science classrooms resulting from collaborative action research initiatives

    Science.gov (United States)

    Oh, Phil Seok

    Collaborative action research was undertaken over two years between a Korean science teacher and science education researchers at the University of Iowa. For the purpose of realizing science learning as envisioned by constructivist principles, Group-Investigations were implemented three or five times per project year. In addition, the second year project enacted Peer Assessments among students. Student perceptions of their science classrooms, as measured by the Constructivist Learning Environment Survey (CLES), provided evidence that the collaborative action research was successful in creating constructivist learning environments. Student attitudes toward science lessons, as examined by the Enjoyment of Science Lessons Scale (ESLS), indicated that the action research also contributed to developing more positive attitudes of students about science learning. Discourse analysis was conducted on video-recordings of in-class presentations and discussions. The results indicated that students in science classrooms which were moving toward constructivist learning environments engaged in such discursive practices as: (1) Communicating their inquiries to others, (2) Seeking and providing information through dialogues, and (3) Negotiating conflicts in their knowledge and beliefs. Based on these practices, science learning was viewed as the process of constructing knowledge and understanding of science as well as the process of engaging in scientific inquiry and discourse. The teacher's discursive practices included: (1) Wrapping up student presentations, (2) Addressing misconceptions, (3) Answering student queries, (4) Coaching, (5) Assessing and advising, (6) Guiding students discursively into new knowledge, and (7) Scaffolding. Science teaching was defined as situated acts of the teacher to facilitate the learning process. In particular, when the classrooms became more constructivist, the teacher intervened more frequently and carefully in student activities to fulfill a

    Schulz, Rachel Corinne

    This study investigated the intended teacher use of a technology-enhanced learning tool, Web-based Inquiry Science Environment (WISE), and the first experiences of teachers new to using it and untrained in its use. The purpose of the study was to learn more about the factors embedded into the design of the technology that enabled it or hindered it from being used as intended. The qualitative research design applied grounded theory methods. Using theoretical sampling and a constant comparative analysis, a document review of WISE website led to a model of intended teacher use. The experiences of four middle school science teachers as they enacted WISE for the first time were investigated through ethnographic field observations, surveys and interviews using thematic analysis to construct narratives of each teachers use. These narratives were compared to the model of intended teacher use of WISE. This study found two levels of intended teacher uses for WISE. A basic intended use involved having student running the project to completion while the teacher provides feedback and assesses student learning. A more optimal description of intended use involved the supplementing the core curriculum with WISE as well as enhancing the core scope and sequence of instruction and aligning assessment with the goals of instruction through WISE. Moreover, WISE projects were optimally intended to be facilitated through student-centered teaching practices and inquiry-based instruction in a collaborative learning environment. It is also optimally intended for these projects to be shared with other colleagues for feedback and iterative development towards improving the Knowledge Integration of students. Of the four teachers who participated in this study, only one demonstrated the use of WISE as intended in the most basic way. This teacher also demonstrated the use of WISE in a number of optimal ways. Teacher confusion with certain tools available within WISE suggests that there may be a

  8. Bringing Classroom-Based Assessment into the EFL classroom

    Directory of Open Access Journals (Sweden)

    Andrew Finch

    2012-01-01

    Full Text Available   This paper describes how English as a Foreign Language (EFL teachers can bring reliable, valid, user-friendly assessment into their classrooms, and thus improve the quality of learning that occurs there. Based on the experience of the author as a an EFL teacher and teacher-trainer, it is suggested that the promotion and development of autonomy, intrinsic motivation, and self-esteem that takes place in a Classroom-Based Assessment (CBA environment facilitates an holistic approach to language learning and prepares the students for the high-stakes tests that often determine their motivation for learning English. Rather than relying on the memorization of language code, form, lexis, and prepared answers, students who have learned in a CBA environment are able to self-assess, peer-assess, build portfolios, and edit their own work. Not only does this reduce the assessment burden on the teacher, but it also develops the skills of problem-solving, critical thinking, and summarization in the students, in addition to a heightened awareness of the language-learning process. By learning how to set goals, assess their achievements, and reflect on their future learning needs, students become more efficient language learners. While acknowledging the place of standardized, summative tests in contemporary society, it is suggested that CBA in the EFL classroom can enhance long-term learning and consequently enable and empower students to prepare for their future learning needs.

    2011-02-01

    Full Text Available First year accounting has generally been perceived as one of the more challenging first year business courses for university students. Various Classroom Assessment Techniques (CATs have been proposed to attempt to enrich and enhance student learning, with these studies generally positioning students as learners alone. This paper uses an educational case study approach and examines the implementation of the IGCRA (individual, group, classroom reflective action technique, a Classroom Assessment Technique, on first year accounting students’ learning performance. Building on theoretical frameworks in the areas of cognitive learning, social development, and dialogical learning, the technique uses reports to promote reflection on both learning and teaching. IGCRA was found to promote feedback on the effectiveness of student, as well as teacher satisfaction. Moreover, the results indicated formative feedback can assist to improve the learning and learning environment for a large group of first year accounting students. Clear guidelines for its implementation are provided in the paper.

    Full Text Available The University of Westminster is undertaking a major classroom refurbishment program that is linked to a new approach to staff development in mobile learning. Feedback obtained from academic staff and students previously highlighted how classrooms should be changed so as to promote more active forms of curriculum delivery. Both technology and classroom furniture were considered significant enablers for effective in-class delivery, with the simplicity of the former and flexibility of the latter identified as key. To date nearly 70 classrooms have been re-designed and the impact of the changes on both staff and students has been assessed. Generally, the feedback has been positive with high praise for the easy to use technology solutions provided and the adaptability of the furniture. In addition, the significance of "getting right" basic features in new classrooms (lighting, acoustics for example was frequently cited by staff and students. This paper will highlight the features of new classrooms that students and staff have indicated they feel are most significant for their learning and teaching experiences. The paper will also assess the extent to which the new classrooms have been successful through analyzing the impact of both new technology and furniture arrangements on approaches to curriculum delivery. In addition, staff views on the utility of the new staff development approach will be discussed.

    Science.gov (United States)

    2001-10-01

    It is the position of the American Dietetic Association to encourage environmentally responsible practices that conserve natural resources, minimize the quantity of waste that is generated, and have the least adverse affect on the health of all living organisms and the environment. All components of the food system, from farmer to consumer, are affected by the availability and cost of energy and the availability and quality of water. Outdoor and indoor air quality significantly impacts the health of all living organisms. Decisions that dietetics professionals make as practitioners and consumers can affect the quantity and type of solid waste generated. The demand for natural resources should be evaluated when selecting the most cost-effective, environmentally sensitive approach to the management of solid waste. Special precautions are needed when using and disposing of hazardous and medical waste to protect the safety of our clients and employees. This position paper provides information and resources for dietetics professionals for addressing the complexity of the environmental issue presented. Conservation strategies are identified that dietetics professionals can use in their worksites and at home. These conservation practices may reduce cost and decrease the environmental impact we have on our communities and the world.

    2015-11-01

    Full Text Available Classroom climate has gained prominence as recent studies revealed its potentials as an effective mediator in the various motivational factors as well as an antecedent of academic performance outcome of the students. This descriptive-correlational study determined the level of classroom climate dimensions among teacher education students specializing in Mathematics at Mindoro State College of Agriculture and Technology. Employing a self-structured questionnaire adapted to the WIHIC (What Is Happening In this Class questionnaire, the surveyed data were treated statistically using Pearson’s r. Result showed that there was high level of classroom climate among the respondents in their Mathematics classes in both teacher-directed and student-directed dimensions specifically in terms of equity, teacher support, cohesiveness, involvement, responsibility and task orientation. Also, it revealed that equity and teacher support were both positively related to the students-directed classroom climate dimensions. With these results, teachers are seen to be very significant determinants of the climate in the classroom. Relevant to this, the study recommended that faculty should develop effective measures to enhance classroom climate dimensions such as equity and teacher support to address the needs of diverse studentsdespite large size classes. Moreover, faculty should provide greater opportunitiesfor the students to achieve higher level of responsibility, involvement, cohesiveness, and task orientation as these could motivate them to develop positive learning attitude, perform to the best of their ability, as well as maximize their full potential in school.

    2015-04-01

    Flipping the classroom centres on the delivery of print, audio or video based material prior to a lecture or class session. The class session is then dedicated to more active learning processes with application of knowledge through problem solving or case based scenarios. The rationale behind this approach is that teachers can spend their face-to-face time supporting students in deeper learning processes. In this paper we provide a background literature review on the flipped classroom along with a three step approach to flipping the classroom comprising implementing, enacting and evaluating this form of pedagogy. Our three step approach is based on actual experience of delivering a flipped classroom at the University of Hong Kong. This initiative was evaluated with positive results. We hope our experience will be transferable to other medical institutions.

    Full Text Available A new paradigm in second language pedagogy has Computer Assisted Language Learning (CALL playing a significant role. Much of the literature to-date claims that CALL can have a positive impact on students’ second language acquisition (SLA. Mixed method of research produces data to investigate if CALL positively affects student language proficiency, motivation and autonomy. Classroom observation of participants in their natural environment is a qualitative technique used but has situational variables that could skew results if not structured. A questionnaire is a quantitative tool that can offer insight regarding participants’ perception of performance but can contradict what the researcher has observed. This paper will take an in-depth look at variables such as: instructor’s pedagogical application; blending CALL into the curriculum; types of CALL implemented; feedback received and their implications for design of the data collection tools

    Immune response to cytomegalovirus (CMV) impacts adult chronic disease. This study investigates associations of childhood and adulthood social environment, socioeconomic position (SEP) and social mobility with CMV response in young adults. Historical prospective study design. Subcohort of all 17 003 births to residents of Jerusalem between 1974 and 1976. Participants included 1319 young adults born in Jerusalem with extensive archival and follow-up data, including childhood and adulthood SEP-related factors and anti-CMV IgG titre levels and seroprevalence measured at age 32. Principal component analysis was used to transform correlated social environment and SEP-related variables at two time points (childhood and adulthood) into two major scores reflecting household (eg, number of siblings/children, religiosity) and socioeconomic (eg, occupation, education) components. Based on these components, social mobility variables were created. Linear and Poisson regression models were used to investigate associations of components and mobility with anti-CMV IgG titre level and seroprevalence, adjusted for confounders. Lower levels of household and socioeconomic components in either childhood or adulthood were associated with higher anti-CMV IgG titre level and seropositivity at age 32. Compared with individuals with stable favourable components, anti-CMV IgG titre level and risk for seropositivity were higher in stable unfavourable household and socioeconomic components (household: β=3.23, P<0.001; relative risk (RR)=1.21, P<0.001; socioeconomic: β=2.20, P=0.001; RR=1.14, P=0.01), downward household mobility (β=4.32, P<0.001; RR=1.26, P<0.001) and upward socioeconomic mobility (β=1.37, P=0.04; RR=1.19, P<0.001). Among seropositive individuals, associations between household components and mobility with anti-CMV IgG titre level were maintained and associations between socioeconomic components and mobility with anti-CMV IgG titre level were attenuated.

    In Canada, public housing programs are an important part of governmental strategies to fight poverty and public exclusion. The Flash on my neighborhood! project is a four-year multiphase community-based participatory action research strategy currently implemented in six public housing developments (n = 1009 households) across the province of Québec, Canada. The goal is to reduce the mental health disparities faced by these public housing tenants compared to the general population, while identifying which environmental and policy changes are needed to turn public housing settings into healthier environments. The protocol involves three successive, interconnected phases: 1) Strengths and needs assessment, including community outreach and recruitment of tenants to collaborate as peer researchers, an exploratory qualitative component (photovoice), a systematic neighborhood observation, and a household survey; 2) Action plan development, including a community forum and interactive capacity-building and discussion sessions; 3) Action plan implementation and monitoring. The entire intervention is evaluated using a mixed-method design, framed within a multiple case study perspective. Throughout the project and particularly in the evaluation phase, data will be collected to record a) contextual factors (tenants' previous experience of participation, history of public housing development, etc.); b) activities that took place and elements from the action plan that were implemented; and c) short- and medium-term outcomes (objective and perceived improvements in the quality of the residential setting, both physically and in terms of mental health and social capital). The study will provide unprecedented evidence-based information on the key ingredients of a collective intervention process associated with the increased collective empowerment and positive mental health of public housing tenants.

  20. HvDep1 Is a Positive Regulator of Culm Elongation and Grain Size in Barley and Impacts Yield in an Environment-Dependent Manner.

    Directory of Open Access Journals (Sweden)

    Toni Wendt

    Full Text Available Heterotrimeric G proteins are intracellular membrane-attached signal transducers involved in various cellular processes in both plants and animals. They consist of three subunits denoted as α, β and γ. The γ-subunits of the so-called AGG3 type, which comprise a transmembrane domain, are exclusively found in plants. In model species, these proteins have been shown to participate in the control of plant height, branching and seed size and could therefore impact the harvestable yield of various crop plants. Whether AGG3-type γ-subunits influence yield in temperate cereals like barley and wheat remains unknown. Using a transgenic complementation approach, we show here that the Scottish malting barley cultivar (cv. Golden Promise carries a loss-of-function mutation in HvDep1, an AGG3-type subunit encoding gene that positively regulates culm elongation and seed size in barley. Somewhat intriguingly, agronomic field data collected over a 12-year period reveals that the HvDep1 loss-of-function mutation in cv. Golden Promise has the potential to confer either a significant increase or decrease in harvestable yield depending on the environment. Our results confirm the role of AGG3-type subunit-encoding genes in shaping plant architecture, but interestingly also indicate that the impact HvDep1 has on yield in barley is both genotypically and environmentally sensitive. This may explain why widespread exploitation of variation in AGG3-type subunit-encoding genes has not occurred in temperate cereals while in rice the DEP1 locus is widely exploited to improve harvestable yield.

    Teachers have come to rely on a variety of approaches in order to elicit and sustain student interest in the classroom. One particular approach, known as gamification, seeks to improve student engagement by transforming the traditional classroom experience into a competitive multiplayer game. Initial attempts at classroom gamification relied on the teacher manually tracking student progress. At the US Air Force Academy, we wanted to experiment with a software gamification tool. Our client/server suite, dubbed Classroom Live, streamlines the gamification process for the teacher by simplifying common tasks. Simultaneously, the tool provides students with an esthetically pleasing user interface that offers in game rewards in exchange for their participation. Classroom Live is still in development, but our initial experience using the tool has been extremely positive and confirms our belief that students respond positively to gamification, even at the undergraduate level.

    Full Text Available Ample research findings support the effective role that classroom management strategies play in enhancing students’ learning. Drawing upon Iranian high school teachers’ classroom management strategies, this article is intended to examine the extent to which these teachers follow assertive classroom management strategies and if these strategies affect students’ performance. Conducting a survey including 123 female students, it was found out that Iranian teachers apply classroom management strategies of organization, teaching management, teacher–student relationship, and teacher punishment–rewards (consequences with varying degrees. In the results section, Pearson correlation is applied between students’ achievement and each part of teacher management strategies. Finally, a positive relationship between teachers’ assertiveness and students’ performance was approved. The findings led to implications for in-service training programs for EFL teachers.

    Although classroom inquiry is the primary pedagogy of science education, it has often been difficult to implement within conventional classroom cultures. This study turned to the alternatively structured Montessori learning environment to better understand the ways in which it fosters the essential elements of classroom inquiry, as defined by prominent policy documents. Specifically, we examined the opportunities present in Montessori classrooms for students to develop an interest in the natural world, generate explanations in science, and communicate about science. Using ethnographic research methods in four Montessori classrooms at the primary and elementary levels, this research captured a range of scientific learning opportunities. The study found that the Montessori learning environment provided opportunities for students to develop enduring interests in scientific topics and communicate about science in various ways. The data also indicated that explanation was largely teacher-driven in the Montessori classroom culture. This study offers lessons for both conventional and Montessori classrooms and suggests further research that bridges educational contexts.

    Ahmet BASAL

    2015-10-01

    Full Text Available Alongside the rise of educational technology, many teachers have been taking gradual but innovative steps to redesign their teaching methods. For example, in flipped learning or a flipped classroom, students watch instructional videos outside the classroom and do assignments or engage in activities inside the classroom. Language teachers are one group of educators exploring the flipped classroom. In foreign language classes, such an approach may offer great benefits for both the teachers and students since classroom time can be applied to more interactive tasks. By extending classroom hours in this way, language teachers can focus on successfully addressing all subjects in the curriculum. The aim of this study is (a to gain insights into the perceptions of prospective English language teachers at a state university in Turkey on flipped classrooms and (b to introduce the implementation of a flipped classroom into an English language class. A total of 47 prospective English teachers participated in the study. Qualitative research design was used and data were collected via an open-ended question. Findings of the study indicated that pre-service English teachers had positive perceptions towards the use of the flipped classroom as an integral part of face-to-face courses. It can be concluded that flipped classroom was beneficial in terms of 4 categories based on the content analysis of the responses: learning at one’s own pace, advance student preparation, overcoming the limitations of class time, increasing the participation in the classroom. The study also provides recommendations towards LMS integration into courses in other English language teaching departments and for implementing flipped classrooms in language teaching.

    2011-09-01

    Mathematics education researchers are asking themselves about why technology has impacted heavily on the social environment and not in the mathematics classroom. The use of technology in the mathematics classroom has not had the expected impact, as it has been its use in everyday life (i.e. cell phone). What about teachers' opinions? Mathematics teachers can be divided into three categories: those with a boundless overflow (enthusiasm) who want to use the technology without worrying much about the construction of mathematical concepts, those who reject outright the use of technology because they think that their use inhibits the development of mathematical skills and others that reflect on the balance that must exist between paper-pencil activities and use of technology. The mathematics teacher, by not having clear examples that support this last option about the balance of paper-pencil activities and technology, opt for one of the extreme positions outlined above. In this article, we show the results of research on a methodology based on collaborative learning (ACODESA) in the training of mathematics teachers in secondary schools and implementation of activities in an environment of paper-pencil and CAS in the mathematics classroom. We also note that with the development of technology on the use of electronic tablets and interactive whiteboards, these activities will take on greater momentum in the near future.

    New teaching approaches for CME are needed. In flipped classrooms, coursework is completed beforehand and applied during class time. Studies of flipped classrooms and their potential benefits in CME have not been published. We sought to develop and validate an instrument measuring flipped classroom perceptions, identify whether participation changed perceptions, and determine which flipped classroom components were perceived as most effective. In this cross-sectional validation study, 167 participants in the Mayo Clinic's 2015 Internal Medicine Board Review course received surveys. Online modules were developed to deliver content before flipped classroom courses on acid-base disorders and electrolyte disorders. A flipped classroom perception instrument (FCPI) was developed and validated. The FCPI, with eight items structured on 5-point Likert scales, was given to participants before and after their flipped classroom experiences. Of the 167 participants, 111 returned surveys. Flipped classroom perceptions improved, with mean (SD) FCPI scores increasing from 3.74 (0.75) to 3.94 (0.76) (P flipped classrooms increased from 38% before the course to 53% after (P = .002). Positive changes in FCPI scores were unrelated to module completion. Most participants thought knowledge was enhanced by in-class sessions and online modules equally. The FCPI, the first validated measure of participants' perceptions of a CME flipped classroom, has strong validity evidence. Participants' perceptions of and preference for the flipped classroom improved after experiencing the flipped CME classroom. These findings support the need to further explore flipped classroom models in CME.

A large percentageof accounting students do not prepare for class and homework is either not doneor neglected. Many factors contributed to students struggling to prepare for classand complete homework assignments. The flipped classroom approach has grownat a rapid pace and was perceived very successful in many subjects. Little researchhas been done on the effectiveness of this approach for accounting students.Videos was created whereby accounting theory was explained and questions withexamples were given and explained. All contact sessions were transformed into anactive learning environment. During contact sessions, students were provided withquestions. Guidance was given with regards to the interpretation of a practicalcase study. Students had to analyze questions before feedback was provided tothem. Contact sessions commenced with easy questions, and progressedto moredifficult questions.Research was conducted in order to determine whether a flipped classroommethod could improve the learning experience of accounting students at a highereducation institution. The study indicated that students watched the videos beforecontact sessions, they felt more positive about their performance in accountingand improved their time management. The majority of students that completed thesurvey preferred the flipped classroom method. It enables students to learn fromtheir own mistakes in class.

    Objective To determine factors that characterizes school environments and their relationship with student learning, welfare and health. Method This is a case study supported by a comprehensive qualitative paradigm applied to classroom ecology. The fieldwork was carried out in six public schools for students in economic strata one and two that use computers in virtual classrooms. The information was collected through field journals, film recordings, observation, and recordings of interviews. The information was analyzed by categories in open general and focused cycles. Results The virtual era has enriched the debate about the importance of the environment in pedagogical processes. Nonetheless, the emergence of new diseases is a risk which students are exposed to. Pollution and overcrowding factors prevail in traditional classroom activities, while in the computer rooms the environment is healthier. Hence the need to incorporate these issues into the curriculum reforms and action plans to guide healthy living of schoolchildren and their families. Despite budget constraints, innovative ideas and projects were found. Schools have developed free preventive and corrective strategies such as workshops, talks and lectures by invited specialists, trainees, and students writing theses. They have also introduced controlled Internet access. Conclusion The educational community understands that the concept of health is at the heart of a comprehensive concept of education.

    2012-04-01

    Over the past twenty-five years researchers have been concerned with understanding the science student. The need for such research is still grounded in contemporary issues including providing opportunities for all students to develop scientific literacy and the failure of school science to connect with student's lives, interests and personal identities. The research reported here is unusual in its use of discourse analysis in social psychology to contribute to an understanding of the way students make meaning in secondary school science. Data constructed for the study was drawn from videotapes of nine consecutive lessons in a year-seven science classroom in Melbourne, post-lesson video-stimulated interviews with students and the teacher, classroom observation and the students' written work. The classroom videotapes were recorded using four cameras and seven audio tracks by the International Centre for Classroom Research at the University of Melbourne. Student talk within and about their science lessons was analysed from a discursive perspective. Classroom episodes in which students expressed their sense of personal identity and agency, knowledge, attitude or emotion in relation to science were identified for detailed analysis of the function of the discourse used by students, and in particular the way students were positioned by others or positioned themselves. This article presents the discursive Umwelt or life-space of one middle years science student, Tasha. Her case is used here to highlight the complex social process of meaning making in science classrooms and the need to attend to local moral orders of rights and duties in research on student language use, identity and learning in science.

    Full Text Available This study aimed to compare the effectiveness of flipped classroom and traditional classroom instruction in measuring conceptual change and to determine if flipped classroom instruction would be an alternative method of teaching to traditional lecture method. This study covered the level of conceptual understanding of students on stoichiometry and the type of conceptual change before and after exposure to flipped and traditional classroom environment. Qualitative and quantitative research methods were used in the study. Respondents were two sections of third year Bachelor of Secondary Education, Biological Science. Frequency, percentage, ranking, mean, standard deviation, Hake factor test, and t-test were the statistical tools applied to answer specific questions. Results showed profound increase towards conceptual change representing a shift from intuitive understanding to correct incomplete understanding level. Thus, change for the better, in theoretical type was determined from pretest to posttest of students exposed to flipped and traditional classroom. Results also indicated that there is no significant difference on students’ conceptual change on stoichiometry exposed to flipped and traditional classroom environment thus, flipped classroom instruction can be used as an alternative teaching method to traditional lecture method in teaching stoichiometry

    Many classrooms in higher education still rely on a transformative approach to teaching where students attend lectures and earn course grades through examination. In the modern age, traditional lectures are argued by some as obsolete and do not address the learning needs of today’s students. An emerging pedagogical approach is the concept of the flipped classroom. The flipped classroom can simply be described as students viewing asynchronous video lectures on their own and then engaging in active learning during scheduled class times. In this study, we examined the flipped classroom teaching environment on student learning gains in an Introduction to Equine Science course. Students (n = 130) were asked to view 7.5 h of recorded lectures divided into 8 learning modules, take online quizzes to enforce lecture viewing, take 3 in-class exams, and prepare to participate in active learning during scheduled class times. Active learning approaches included individual activities, paired activities, informal small groups, and large group activities. When compared to students in the traditional lecture format in earlier years, students in the flipped format scored higher on all 3 exams (P flipped format students were asked to take the Cornell Critical Thinking Exam (version X). Scores improved from the pretest (50.8 ± 0.57) to the posttest (54.4 ± 0.58; P flipped course, no correlations were found with student performance and interactions with online content. Students were asked in class to evaluate their experiences based on a 5-point Likert scale: 1 (strongly disagree) to 5 (strongly agree). The flipped classroom was ranked as an enjoyable learning experience with a mean of 4.4 ± 0.10, while students responded positively to other pointed questions. In formal course evaluations, flipped format students ranked the following higher (P flipped classroom proved to be a positive learning experience for students.

    The purpose of this study was to examine whether approaches to learning moderated the association between child care classroom environment and Head Start children's academic skills. The data came from the Head Start Family and Child Experiences Survey (FACES-2003 Cohort). The dataset is a nationally representative longitudinal study of Head Start children. The sample was selected using the stratified 4-stage sampling procedure. Data was collected in fall 2003, spring 2004, spring 2005, and spring 2006 in the first year of kindergarten. Participants included 3- and 4-year-old Head Start children (n = 786; 387 boys, 399 girls; 119 Hispanic children, 280 African American children, 312 Caucasian children). Head Start children's academic skills in letter-word identification, dictation/spelling, and mathematics at the 4 time points were measured by the Woodcock-Johnson Achievement Battery tests. Approaches to learning in fall 2003 was measured by the teacher report of the Preschool Learning Behaviors Scale. Child care classroom quality in fall 2003 was measured by the revised Early Childhood Environment Rating Scale. Results of the linear mixed effects models demonstrated that approaches to learning significantly moderated the effect of child care classroom quality on Head Start children's writing and spelling. Specifically, positive approaches to learning mitigated the negative effect of lower levels of classroom quality on dictation/spelling. Results underscore the important role of approaches to learning as a protective factor. Implications for early childhood educators with an emphasis on learning goals for disengaged children are discussed. (c) 2015 APA, all rights reserved).

    Young children exhibiting severe externalizing problems in school are at risk of developing several poor outcomes. School-based intervention programs have been found to be effective for students with different problems, including those with behavioral problems, emotional distress, or social problems. The present study investigated whether the IY-TCM programme, as a universal stand-alone school intervention programme, reduced severe child externalizing problems as reported by the teacher, and evaluated if these children improved their social competence, internalizing problems, academic performances and student- teacher relationship as a result of the IY TCM training. A quasi-experimental pre-post study was conducted, including 21 intervention schools and 22 control schools. Children in 1 st - 3 rd grade (age 6-8 years) assessed by their teacher as having severe externalizing problems on the Sutter-Eyberg Student Behavior Inventory-Revised (SESBI-R) total Intensity score, were included in the study, N = 83 (65 boys and 18 girls). Treatment effects were evaluated using 3- level linear mixed models analysis. In our study we found no differences in change between the two conditions from baseline to follow-up in externalizing problems, social skills, internalizing problems and closeness with teacher. The intervention condition did however show advantageous development in terms of student-teacher conflicts and increased academic performances. The IY Teacher Classroom Management program is not sufficient being a stand-alone universal program in a Norwegian primary school setting, for students with severe externalizing problems. However; some important secondary findings were found. Still, young school children with severe externalizing problems are in need of more comprehensive and tailored interventions.

    Guided by the person by environment framework, the primary goal of this study was to determine whether classroom chaos moderated the relation between effortful control and kindergarteners' school adjustment. Classroom observers reported on children's ( N = 301) effortful control in the fall. In the spring, teachers reported on classroom chaos and school adjustment outcomes (teacher-student relationship closeness and conflict, and school liking and avoidance). Cross-level interactions between effortful control and classroom chaos predicting school adjustment outcomes were assessed. A consistent pattern of interactions between effortful control and classroom chaos indicated that the relations between effortful control and the school adjustment outcomes were strongest in high chaos classrooms. Post-hoc analyses indicated that classroom chaos was associated with poor school adjustment when effortful control was low, suggesting that the combination of high chaos and low effortful control was associated with the poorest school outcomes.

    Young children with autism spectrum disorder (ASD) often demonstrate delays in expressive communication, impacting their ability to independently function in typical environments. Individuals with ASD who develop expressive language during early childhood experience better outcomes later in life; therefore, examination of naturalistic language interventions (NLIs) remain an important area of investigation. The current study used a multiple probe design across participants to examine the effects of a classroom-based NLI on various expressive language targets in three preschool-aged children demonstrating characteristics of ASD. Findings suggest the intervention had positive and maintained effects on trial-based use of language targets, as well as concomitant changes in commenting, requesting, and phrase complexity. Implications regarding implementation of NLIs within typical classroom play activities are discussed.

  14. Focusing elementary students with active classrooms: exploring teachers’ perceptions of self-initiated practices

    Christine A. Foran

    2017-09-01

    Full Text Available The aim of our study was to explore the perceptions of elementary teachers who routinely prioritized physical activity in their classrooms. Researchers are reporting improved student academic test results following physical activity sessions, however, classroom teachers are challenged in balancing curricular and other expectations. Hence, teachers who voluntarily implement physical activity have views that are unique and important for promoting the practice to others. We interviewed seven teachers from grades 1-6, using the qualitative constructivist approach to grounded theory qualitative research. Teachers valued physical activity because it enhanced their students’ focus on classroom activities. Common attributes amongst the teachers were active lifestyles, previous employment experiencesusing physical activity, and a pedagogical approach prioritizing physical activity throughout the day. Additionally, the teachers perceived that belonging to schools with a culture of movement was important. Teachers view physical activity as a teaching asset when they perceive a positive impact on their students’ ability to focus. Specific teacher attributes and a school environment that embraces physical activity may predispose teachers to these views, and represent areas that should be further explored. Pre-service courses could be one way to provide teachers with experience and a repertoire of easy physical activities.

    Baker, Dale

    This study examined the effects of single-sex middle school science and mathematics classrooms with high minority enrollment on achievement, affect, peer, and teacher-student interactions. All students earned higher grades in mathematics than in science. Girls earned higher grades than boys. The higher grades of girls were not clearly attributable to the singlesex environment, and aspects of the single-sex environment interfered with boys' achievement. The single-sex environment contributed to girls', but not boys', feelings of empowerment, peer support, and positive self-concept. The curriculum and pedagogy were better suited to girls than to boys, leading to discipline problems and hostile interactions. However, boys were more engaged in technology-based activities than girls. Overall, all-boy classes were less supportive learning environments than all-girl classes. Although the results replicate findings elsewhere, this is the only study to look at minority students in middle school.

    needed. For all the countries investigated, with the exception of Singapore, the between-class variance was much smaller than the within-class variance. Japan had the smallest variation in science achievement among classrooms which indicates the homogeneity across classrooms in Japan. Increasing awareness and knowledge of gender neutral instructional techniques, providing a non-threatening, rich and supportive environment for both genders in classrooms by elementary teachers are to be encouraged. To improve students' self beliefs about science, it is recommended that teachers model science activities and accommodate students' needs and abilities (Bandura, 1997; Britner & Pajares, 2006). Schools and teachers are recommended to develop a successful home-school partnership for improved student learning and positive attitudes toward science (Eccles & Harold, 1996; Epstein & Salinas, 2004). Furthermore, developing a knowledge base for teachers regarding the influences of classroom and school composition is highlighted (Honig, Kahne, & McLaughlin, 2001; Murrel, 2001). At the classroom- and school-level, policy efforts could focus on the distribution of educational resources (Condron & Roscigno, 2003; Goesling, 2003) to compensate for poor family background.
