Traditionally the roles of schools and parents have been seen as separate activities. More recently, a view has developed that parents and schools should work together in a close and integrated relationship. The writer discusses the nature of this partnership and the roles of both parents and teachers in it. The nature of the school–parent relationship in Israel is considered. In the final section of the paper, the development of such a partnership in a particular Israeli elementary school is described and evaluated. 相似文献

While homework is a frequent source of distress, positive attitudes of parents can help students develop positive emotions and self-efficacy regarding homework. In this study, we tested the hypothesis that parents' emotions, favored by autonomous motivation, directly and indirectly relate with students' emotions through their self-efficacy with regard to homework. Questionnaires were administered to 205 fourth- to eighth-grade students and their parents to assess both groups' positive and negative emotions, students' self-efficacy with regard to homework, and parents' autonomous motivation. The results supported the hypothesized model: parents' autonomous motivation is associated with parents' positive emotions, which is then associated with students' positive and negative emotions, both directly and through the mediation of students' self-efficacy for doing homework. The discussion focuses on theoretical and educational implications. 相似文献

Child abuse is a social problem that receives much attention from policy makers, practitioners, and researchers. This alarming phenomenon generates many consequences for children, their families, and society as a whole; one tragic consequence of child abuse is filicide. Because of the unfortunate circumstances surrounding such events, children are hushed by their perpetrators, whether abusers or killers, and we are thus denied the opportunity to hear their voices and to promote understanding of the phenomenon. The aim of the current study is to explore in depth the patterns and themes that can be found in the narratives of children who survived a murder attempt by one of their parents. Content analysis was performed on seven investigative interviews with children using thematic analysis. Five key categories were determined based on the children's narratives: (a) many bad things have happened to me, (b) this was not the first time I was abused by my parent, (c) I am concerned about my parent, (d) I am alive thanks to my siblings, and (e) it is hard to remember what exactly happened. This study contributes to the understanding of child physical abuse and filicide. The discussion integrated conclusions for policy makers and practitioners who seek methods of addressing child abuse as well as determining whether and how filicide can be prevented. 相似文献

The current study investigated how item formats and their inherent affordances influence test‐takers’ cognition under uncertainty. Adult participants solved content‐equivalent math items in multiple‐selection multiple‐choice and four alternative grid formats. The results indicated that participants’ affirmative response tendency (i.e., judge the given information as True) was affected by the presence of a grid, type of grid options, and their visual layouts. The item formats further affected the test scores obtained from the alternatives keyed True and the alternatives keyed False, and their psychometric properties. The current results suggest that the affordances rendered by item design can lead to markedly different test‐taker behaviors and can potentially influence test outcomes. They emphasize that a better understanding of the cognitive implications of item formats could potentially facilitate item design decisions for large‐scale educational assessments. 相似文献

This paper uses scale-independent indicators to explore the Chinese national and regional innovation systems during economic transition. Our perception of an innovation system is frequently informed by conventional indicators based on linear assumptions while actually innovation systems may behave differently. Scale-independent indicators characterize non-linear properties of an innovation system. They can give decision makers deeper insight into the dynamics of innovation systems, and they may lead to more practical public policies [Katz, J. S. (2006). Indicators for complex innovation systems. Research Policy, 35, 893–909].As reported for the European and Canadian innovation systems the Chinese systems exhibited scaling correlations between GERD (Gross Expenditure on Domestic R&D) and GDP (Gross Domestic Product) over time and at points in time. The scaling factors of the correlations tell us that between 1995 and 2005 the Chinese GERD exhibited a strong non-linear tendency to increase with GDP. Furthermore they show that the GERD of the Western region is growing much slower than its GDP as compared with Eastern and Central regions. This observation has policy implications suggesting further improvements need to be made to the research infrastructure and funding of the Western region.The GDP–POP (Population) scaling factor shows that the ‘wealth intensity’ or GDP per capita is increasing much faster than the exponential growth of the Chinese population. In contrast the systemic GDP–POP scaling factor shows that regional development is non-linear. Finally, the paper–GDP and patent–GDP scaling factors tell us that outputs of science and technology for China are growing faster than economic growth. The systemic paper–GDP and patent–GDP scaling factors show that the growth rates are uneven across the provinces. 相似文献

Three pigeons were trained in a three-item simultaneous same/different task. Three of six stimulus combinations were not trained (untrained set) and were tested later. Following acquisition, the
subjects were tested with novel stimuli, the untrained set, training-stimulus inversions, and object shape and color manipulations.
There was no novel-stimulus transfer—that is, no abstract-concept learning. Two pigeons showed partial transfer to untrained
pairs and good transfer to stimulus inversions, suggesting that they had learned the relationship between the stimuli. Lack
of transfer by the third pigeon suggests item-specific learning. The somewhat surprising finding of relational learning by
2 pigeons with only six training pairs suggests restricted-domain relational learning that was controlled more by color than
by shape features. Individual differences of item-specific learning by 1 pigeon and relational learning by 2 others demonstrate
that this task can be learned in different ways and that relational learning can occur in the absence of novel-stimulus transfer. 相似文献

The aim of this study was to determine the biomechanical parameters that explain ventral start performance in swimming. For this purpose, 13 elite swimmers performed different variants of the ventral start technique. Two-dimensional video analyses of the aerial and underwater phases were used to assess 16 kinematic parameters from the starting signal to 5?m, and an instrumented starting block was used to assess kinetic data. A Lasso regression was used to reduce the number of parameters, providing the main determinants to starting performance, revealing different combinations of key determinants, depending on the variant (r²?≥?0.90), with flight distance being the most relevant to all variants (r?≤??0.80; p?.001). Also, special attention should be given to the total horizontal impulse in the grab start (r?=??0.79; p?.001) and to the back foot action in the track and kick starts (r?≤?0.61; p?.001). In addition, we provide two equations that could be easily used to predict starting performance by assessing block time and flight time (r²?=?0.66) or block time and flight distance (r²?=?0.83). These data provide relevant contributions to the further understanding of the biomechanics of swimming starts as well as insights for performance analysis and targeted interventions to improve athlete performance. 相似文献
