Privatisation, Decentralisation And Governance In Education In The Czech Republic, England, France, Germany And Sweden     

Holger Daun 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》2004,5(3):325-346

The Czech Republic, England, France, Germany and Sweden differ culturally and economically, but they commonly exhibit general trends of decentralisation in the control of educational processes and outcomes. The present contribution looks at these five European countries as the venue for case studies in educational restructuring as well as evaluation, assessment and reporting. It shows that such trends have been most radical in the Czech Republic and Sweden, while England has centralised curriculum policy and France has devolved some decision-making to bodies at lower levels, but as representatives of the central state.  相似文献   

On some psychological aspects of mathematics achievement assessment and classroom interaction     

Jenz Holger Lorenz 《Educational Studies in Mathematics》1982,13(1):1-19

The way students and teachers evaluate mathematics achievement differs in certain respects. To which causal performance is ascribed determines the teacher's strategy to interact with the student on the one hand and influences the student's willingness to invest additional effort on the other. Certain possible causal factors for success and failure in mathematics and their relation to teacher-student-interaction are discussed in the present article. A rather general cognitive scheme, the teachers reference norm, explains differences between the teacher's perception and assessment of student characteristics and subsequent teaching interventions.  相似文献   

Residents’ perceptions of mega sport event legacies and impacts     

Anja Scheu  Holger Preuss 《Sportwissenschaft》2018,48(3):376-386

The purpose of this study was to examine perceptions of local residents prior to the public referendum for the 2024 Hamburg Olympic bid and to assess their level of support for the bid. The representative survey conducted amongst Hamburg residents reveals a high level of support but also a strong perception of negative legacies. A comparison between the perceived positive and negative legacies shows that the negative legacies outweigh the positive legacies. When examining factors that influence support, statistical analysis reveals the perception of positive legacies as the strongest predictor of support. The survey also indicates that residents attach great importance to the costs of the Games and feel no personal benefit from hosting them. The findings suggest that Games organizers and authorities should mostly rely on positive legacies while negative legacies ought to be mitigated.  相似文献   

A fluorescence based method for the quantification of surface functional groups in closed micro- and nanofluidic channels

Surface analysis is critical for the validation of microfluidic surface modifications for biology, chemistry, and physics applications. However, until now quantitative analytical methods have mostly been focused on open surfaces. Here, we present a new fluorescence imaging method to directly measure the surface coverage of functional groups inside assembled microchannels over a wide dynamic range. A key advance of our work is the elimination of self-quenching to obtain a linear signal even with a high density of functional groups. This method is applied to image the density and monitor the stability of vapor deposited silane layers in bonded silicon/glass micro- and nanochannels.  相似文献   

A Nonlinear Dynamic Latent Class Structural Equation Model     

Augustin Kelava  Holger Brandt 《Structural equation modeling》2019,26(4):509-528

In this article, we propose a nonlinear dynamic latent class structural equation modeling (NDLC-SEM). It can be used to examine intra-individual processes of observed or latent variables. These processes are decomposed into parts which include individual- and time-specific components. Unobserved heterogeneity of the intra-individual processes are modeled via a latent Markov process that can be predicted by individual- and time-specific variables as random effects. We discuss examples of sub-models which are special cases of the more general NDLC-SEM framework. Furthermore, we provide empirical examples and illustrate how to estimate this model in a Bayesian framework. Finally, we discuss essential properties of the proposed framework, give recommendations for applications, and highlight some general problems in the estimation of parameters in comprehensive frameworks for intensive longitudinal data.  相似文献   

Comprehending conflicting science-related texts: graphs as plausibility cues     

Maj-Britt Isberner  Tobias Richter  Johanna Maier  Katja Knuth-Herzig  Holger Horz  Wolfgang Schnotz 《Instructional Science》2013,41(5):849-872

When reading conflicting science-related texts, readers may attend to cues which allow them to assess plausibility. One such plausibility cue is the use of graphs in the texts, which are regarded as typical of ‘hard science’. The goal of our study was to investigate the effects of the presence of graphs on the perceived plausibility and situation model strength for conflicting science-related texts, while including the influence of readers’ amount of experience with scientific texts and graphs as a potential moderator of these effects. In an experiment mimicking web-based informal learning, 77 university students read texts on controversial scientific issues which were presented with either graphs or tables. Perceived plausibility and situation model strength for each text were assessed immediately after reading; reader variables were assessed several weeks prior to the experiment proper. The results suggest that graphs can indeed serve as plausibility cues and thus boost situation model strength for texts which contain them. This effect was mediated by the perceived plausibility of the information in the texts with graphs. However, whether readers use graphs as plausibility cues in texts with conflicting information seems to depend also on their amount of experience with scientific texts and graphs.  相似文献
