School politics in Sweden has recently moved in a conservative direction, emphasising the importance of conventional school subjects, stronger teacher authority and more discipline in the classroom. At the same time, consensus on the utility of such measures is lacking in the school debate. The conservative approach is often criticised as misleading and behind the times in relation to contemporary knowledge demands. This article examines and discusses the relevance of this critique. The main argument is that the conservative approach has a better matching with a previous phase in the history of Swedish school politics and that conventional schooling is difficult to combine with two of the major goals of schooling today – the diffusion of democracy and multipurpose skills. From this perspective, the political notion of schooling seems decoupled from the broader domain of public demands on education. To alleviate this problem school politics should draw less on the pedagogical ideas of essentialism and more on the historical legacy of progressivism in the Swedish education system. 相似文献

In this article, we present an approach for comprehensive analysis of the effectiveness of interventions based on nonlinear structural equation mixture models (NSEMM). We provide definitions of average and conditional effects and show how they can be computed. We extend the traditional moderated regression approach to include latent continous and discrete (mixture) variables as well as their higher order interactions, quadratic or more general nonlinear relationships. This new approach can be considered a combination of the recently proposed EffectLiteR approach and the NSEMM approach. A key advantage of this synthesis is that it gives applied researchers the opportunity to gain greater insight into the effectiveness of the intervention. For example, it makes it possible to consider structural equation models for situations where the treatment is noneffective for extreme values of a latent covariate but is effective for medium values, as we illustrate using an example from the educational sciences. 相似文献

Although many theories mention distractions by conflicting alternatives as a problem for self-regulation, motivational conflicts are rarely considered when explaining impairments in learning. In two studies, we investigate the assumption of motivational interference theory that students show different amounts of impairments in learning depending on the presence and motivational strength of conflicting alternatives. In Study 1 (N?=?221), the subjective value attributed to a respective alternative in a study–leisure conflict scenario partially accounted for differences in self-regulated learning while controlling for interindividual differences. Study 2 (N?=?112) demonstrated that this pattern applies to both when the respective alternatives refer to ‘liking to’ (want conflicts) and ‘having to’ (should conflicts) do something. Moreover, it is demonstrated that impairments due to motivational conflict are higher than impairments inherent in the studying activity itself (baseline). The results emphasise the importance of concurring action alternatives for explaining difficulties in self-regulated learning. 相似文献

Analytical methods to assess thigh muscle balance need to provide reliable data to allow meaningful interpretation. However, reproducibility of the dynamic control ratio at the equilibrium point has not been evaluated yet. Therefore, the aim of this study was to compare relative and absolute reliability indices of its angle and moment values with conventional and functional hamstring–quadriceps ratios. Furthermore, effects of familiarisation and angular velocity on reproducibility were analysed. A number of 33 male volunteers participated in 3 identical test sessions. Peak moments (PMs) were determined unilaterally during maximum concentric and eccentric knee flexion (prone) and extension (supine position) at 0.53, 1.57 and 2.62 rad · s–1. A repeated measure, ANOVA, confirmed systematic bias. Intra-class correlation coefficients and standard errors of measurement indicated relative and absolute reliability. Correlation coefficients were averaged over respective factors and tested for significant differences. All balance scores showed comparable low-to-moderate relative (<0.8–0.9) and good absolute reliability (<10%). Relative reproducibility of dynamic control equilibrium parameters augmented with increasing angular velocity, but not with familiarisation. At 2.62 rad · s–1, high (moment: 0.906) to moderate (angle: 0.833) relative reliability scores with accordingly high absolute indices (4.9% and 6.4%) became apparent. Thus, the dynamic control equilibrium is an equivalent method for the reliable assessment of thigh muscle balance. 相似文献

Prematurity may cause hippocampal compromise. Therefore, hippocampus‐dependent memory processes (recollection‐based retrieval) may be more impaired than hippocampus‐independent processes (familiarity‐based retrieval). The memory of 18 children born preterm with reduced hippocampal volumes, without neonatal complications (weeks of gestation < 34, weight < 1,600 g), and 15 controls (8–10 years) was tested using an item recognition task. While groups were equal in memory performance, dissociation was found: The event‐related potential (ERP) correlate of familiarity was intact in the preterm group, whereas the correlate of recollection was attenuated. A follow‐up experiment ruled out that this was due to general cognitive deficits. Furthermore, gestational age correlated with the ERP index of recollection. Thus, recognition memory in preterm children may be characterized by a compensation of attenuated recollection by familiarity. 相似文献

Phonics, fluency, and reading strategy trainings are evidence-based interventions that foster the reading skills of poor readers in primary school. The purpose of the present study was to compare differential effects of the three types of trainings on the efficiency of component processes on word, sentence, and text level immediately after the training and at a 3-month follow-up. The 235 poor readers were randomly allocated to one of the reading interventions or to a control condition. All interventions consisted of 25 sessions that were scheduled twice a week and lasted 45 min. Results indicated short-term effects of the phonics training and the strategy training on the efficiency of a broad range of word-level and sentence-level processes. None of the treatment effects persisted over the long term, indicating the need for instructional efforts to regularly practice the acquired skills after the actual training. 相似文献

Edgar Allan Poe’s standing as a literary figure, who drew on (and sometimes dabbled in) the scientific debates of his time, makes him an intriguing character for any exploration of the historical interrelationship between science, literature and philosophy. His sprawling ‘prose-poem’ Eureka (1848), in particular, has sometimes been scrutinized for anticipations of later scientific developments. By contrast, the present paper argues that it should be understood as a contribution to the raging debates about scientific methodology at the time. This methodological interest, which is echoed in Poe’s ‘tales of ratiocination’, gives rise to a proposed new mode of—broadly abductive—inference, which Poe attributes to the hybrid figure of the ‘poet-mathematician’. Without creative imagination and intuition, Science would necessarily remain incomplete, even by its own standards. This concern with imaginative (abductive) inference ties in nicely with his coherentism, which grants pride of place to the twin virtues of Simplicity and Consistency, which must constrain imagination lest it degenerate into mere fancy. 相似文献

Business opportunities in international markets are largely determined by accessibility, transparency, and legal frameworks
fair to all parties concerned. Arab book markets in principle offer a tremendous potential with more than 300 million readers
sharing one common language. Besides unsolved censorship issues, problems with money collection, and differing regulations,
however, the lack of a uniform book distribution system is the most critical hurdle for the development of a common Arabic
book market. Most importantly, there is no comprehensive database containing accurate content briefs, background information
on authors, ISBN numbers, and publisher company information as well as all relevant commercial data such as book prices, weight,
logistics terms, and availability. Authors and publishers are hard hit as they often need to organize book transportation,
delivery, and invoice collection on their own. At present, “selling book fairs” in the Arab world—with the exception of Abu
Dhabi International Book Fair—present themselves as crowded book bazaars rather than executive meeting points. The authors
of the article, however, are anticipating change: New distribution initiatives will soon interlink regional Arabic markets
and create unique growth and profit opportunities. 相似文献
