We tested some of the key predictions of processing efficiency theory using a simulated rally driving task. Two groups of participants were classified as either dispositionally high or low anxious based on trait anxiety scores and trained on a simulated driving task. Participants then raced individually on two similar courses under counterbalanced experimental conditions designed to manipulate the level of anxiety experienced. The effort exerted on the driving tasks was assessed though self-report (RSME), psychophysiological measures (pupil dilation) and visual gaze data. Efficiency was measured in terms of efficiency of visual processing (search rate) and driving control (variability of wheel and accelerator pedal) indices. Driving performance was measured as the time taken to complete the course. As predicted, increased anxiety had a negative effect on processing efficiency as indexed by the self-report, pupillary response and variability of gaze data. Predicted differences due to dispositional levels of anxiety were also found in the driving control and effort data. Although both groups of drivers performed worse under the threatening condition, the performance of the high trait anxious individuals was affected to a greater extent by the anxiety manipulation than the performance of the low trait anxious drivers. The findings suggest that processing efficiency theory holds promise as a theoretical framework for examining the relationship between anxiety and performance in sport.  相似文献

Thirty-three children with a range of intellectual disabilities who participated in a transition program embedded within a model inclusive preschool program were enrolled in mainstream kindergarten classes from 1995 to 1999. In the second of four kindergarten terms the classroom survival skills, on-task behaviour across a range of activities and following teacher directions, were measured by observing the children with intellectual disabilities and a typical peer, nominated by each classroom teacher. While the teacher-nominated peers outperformed the students with intellectual disabilities in total time-on-task, the level achieved by the children with intellectual disabilities was still at the lower end of what is regarded as average. There was no statistical difference between the two groups in on-task behaviour during independent activities but the difference between the groups during whole class instruction was highly significant. This may have implications for the selection of strategies for preparing children for transition and the adaptation of teaching practices. On-task behaviour did not vary a great deal across level of intellectual disability but gender may have been a contributing factor. There appeared to be a greater difference between students with and without disabilities in responding to teacher directions. The results of the present study suggest that successful demonstration of these critical skills requires more appropriate teacher preparation and intervention at the kindergarten level.  相似文献

Heat effects in fixed-bed sorption columns are often quite large and have a pronounced effect on the sorption kinetics. Proper design of such systems must include consideration of these effects.A method is developed for computing the maximum possible bed temperature. The model is tested on two systems: (1) the Linde molecular sieve 4 A/water system and (2) the Alcoa activated alumina F-1/water system. Since the predicted temperatures appeared to be low for the latter system, the model was refined by the inclusion of the isosteric integral heat of adsorption. Tests on the activated alumina show considerable improvement.The isosteres of two sorption therm correlations are investigated. The results show that the heat of adsorption of water on the alumina varies logarithmically with sorbate concentration—approaching high values at low concentrations and approaching the heat of vaporization of water at high concentrations. The results also suggest that the isosteric heat of adsorption behavior may be of use in assessing the “goodness of fit” of sorption therm correlations.  相似文献

Community financing is an important source of supplementary funds for education, particularly where governments are unable to meet all the needs of their peoples. While this is widely recognised, little empirical research has been conducted on the topic. This paper analyses patterns in Bhutan. It observes that until the 1990s few resources for education were provided by communities, but that the scale of financing has increased during the present decade. The paper notes that although communities have in general responded positively to government calls for local inputs, local resourcing has some problematic aspects. The paper focuses particularly on issues of regional, rural/urban and socio-economic equity, and shows how discussion of Bhutanese experiences contributes to the international literature.
Zusammenfassung Finanzierungen über die Gemeinde sind eine wichtige Quelle der Bezuschussung von Bildung, besonders dort, wo Regierungen nicht in der Lage sind, den Bedürfnissen der Bevölkerung gerecht zu werden. Obwohl dies weitreichend bekannt ist, gibt es kaum empirische Studien zu diesem Thema. Dieser Artikel befaßt sich mit der Situation in Bhutan. Es wird festgestellt, daß die Gemeinden bis zu den 90ern kaum Gelder für die Bildung zur Verfügung stellten, daß aber der Rahmen der Finanzierung in diesem Jahrzehnt gestiegen ist. Der Autor beschreibt, daß trotz einer allgemein positiven Antwort seitens der Gemeinden auf Forderungen der Regierung nach lokalen Finanzbeiträgen, Probleme hinsichtlich lokaler Finanzierungen bestehen. Insbesondere befaßt sich der Artikel mit Themen über regionale, ländliche und städtische und sozialökonomische Gleichheit und zeigt, wie die Diskussion über die Erfahrungen in Bhutan zur internationalen Literatur beiträgt.

Resumen La financiación a través de la comunidad es una fuente importante de recursos adicionales para la educación, particularmente allí donde los gobiernos son incapaces de satisfacer todas las necesidades de sus habitantes. Si bien este es un hecho ampliamente conocido, existen muy pocos estudios empíricos sobre este tema. El trabajo analiza los modelos existentes en Bhután y observa que hasta los años noventa, eran pocos los recursos financieros provistos por las comunidades, mientras que durante la década actual han aumentado estos niveles de financiación. El estudio observa que, a pesar de que las comunidades, en general, han respondido de forma positiva a las llamadas del gobierno a realizar inversiones locales, la creación de recursos locales tiene algunos aspectos problemáticos. El trabajo se concentra particularmente en problemas de equidad regional, rural/urbana y socioeconómica, demostrando cómo la discusión sobre experiencias bhutanesas presta su aporte a la literatura internacional.

Résumé Le financement communautaire représente une source importante de fonds supplémentaires pour l'éducation, en particulier quand le gouvernement ne peut répondre à tous les besoins de la population. Bien que ce fait soit largement reconnu, il n'existe que peu de recherche empirique sur le sujet. Cet article analyse différents modèles existant au Bhoutan. Il constate tout d'abord que jusque dans les années 90, les communautés ne fournissaient qu'une faible partie des ressources de l'éducation, mais que cette forme de financement a augmenté au cours de la dernière décennie. Il relève également qu'en dépit de la réaction généralement positive de la part des communautés envers l'incitation du gouvernement à un financement local, ce modèle présente néanmoins des difficultés. L'article se concentre d'autre part sur les questions d'équitabilité entre régions, entre villes et provinces et entre niveaux socioéconomiques, et révèle que la discussion sur les expériences du Bhoutan contribue à enrichir la littérature internationale.

Writing is critical for college and career readiness, yet secondary students in America are not good writers (National Center for Education Statistics, 2012). Unfortunately, researchers know relatively little about secondary students’ writing skills, and even less about their digital writing. In this study, we explored prior computer use, keyboard activity during writing, and their relations to writing achievement using the 8th grade 2011 National Assessment of Educational Progress writing assessment, the first national computer-based writing assessment for U.S. secondary students. We found that prior computer use predicted students’ writing skills directly (0.08) and indirectly (e.g., keypresses, 0.14) via keyboard activity during the test. We found differential effects for certain groups including current English learners and disadvantaged students. We also found a small positive interaction effect of prior use and keypresses on writing. That is, the benefits of prior computer use for school writing and the value of students’ additional keypresses on writing achievement were amplified when both were present.

Previous literature has demonstrated that networks can be valuable sources of professional learning. In 2005 all Liverpool schools formed into ten Learning Networks with the aim of improving the quality, and entitlement of, continuing professional development (CPD) for staff as part of a whole-scale local authority initiative. The Liverpool Learning Networks Research explored professionals’ CPD experiences following this organizational change and whether it has enhanced their practice. Triangulated data, a large-scale survey and qualitative interviews conducted in 2007, seem to suggest that where professionals benefited from professional learning in a networked context, the quality of the networked CPD as well as a positive school culture and intra-school collaboration were all important contributors to the success of networked-CPD. This finding can usefully apply Turbill’s (Teacher learning for educational change. Open University Press, Buckingham, 94–114, 2002) model of professional learning to the intersection between school-based and networked-CPD, which suggests that it is at this intersection between internal and external domains that teacher learning can take place. Two scenarios, where this interplay between school-based and networked CPD is positive (enhancement) or negative (tension), are reported through five case studies of professionals underpinned by the survey data, where relevant.  相似文献

Objective. Parenting behavior is presumed to be related to the thoughts about child behavior that parents report in a controlled and explicit manner and to more implicit parent cognitions that occur outside of conscious awareness and are less accessible to verbal report. Design. We examined mothers’ attitudes toward their children as correlates of self-reported parenting behavior. We used a combination of a self-report questionnaire and a reaction-time method (the Implicit Association Test) to assess explicit and implicit attitudes, respectively. We also assessed mothers’ implicit and explicit attributions for child misbehavior in relation to parenting, using a questionnaire measure of attributions completed under high-cognitive load (implicit attributions) or under low-cognitive load (explicit attributions). Mothers of 124, 6- to 10-year-olds (52% male) participated. Results. Attitudes assessed by self-report questionnaire and the Implicit Association Test were uniquely associated with negative parenting. The cognitive load manipulation moderated associations between attributions and parenting, such that child-blaming attributions were inversely associated with positive parenting only under conditions of high-cognitive load. Conclusions. Compared to traditional self-report questionnaires, methods such as the Implicit Association Test or cognitive load manipulations may more effectively assess implicit parent cognitions.  相似文献

The aim of this study was to examine the relationship between shoulder alignment and elbow angle during the delivery action of fast-medium bowlers. The elbow and upper trunk alignment were recorded for 13 high-performance bowlers (mean age 20 years) using a 12-camera Vicon motion analysis system operating at 250 Hz. The three highest velocity trials for "good" and "short" length deliveries were analysed. Results showed that bowlers with a more front-on shoulder alignment at back-foot impact and when the upper arm was horizontal to the ground experienced a significantly greater elbow flexion--extension range when compared with those who had a more side-on orientation at the same point in the delivery action. Bowlers with greater shoulder counter-rotation also recorded higher elbow flexion and subsequently extension during the period from upper arm horizontal to ball release. Shoulder alignment and elbow angles were similar for "short" and "good" length deliveries. It was concluded that bowlers with a more front-on shoulder orientation at back-foot impact demonstrated a higher elbow extension from upper arm horizontal to ball release and are therefore more likely to infringe International Cricket Council elbow tolerance levels, compared with those who adopt a more side-on shoulder orientation at back-foot impact.  相似文献

The purpose of this article is to enumerate a series of security steps that might be taken by those researchers or organizations that are contemplating web-based tests and performance assessments. From a security viewpoint, much of what goes on with web-based transactions is similar to other general computer activity, but the recommendations here focus on what can be done to avoid the loss, compromising, or modification of data collected by or stored through the Internet.  相似文献
