New technology poses new moral problems for children to consider. We examined whether children deem object tracking with a mobile GPS device to be a property right. In three experiments, 329 children (4–10 years) and adults were asked whether it is acceptable to track the location of either one's own or another person's possessions using a mobile GPS device. Young children, like adults, viewed object tracking as relatively more acceptable for owners than nonowners. However, whereas adults expressed negative evaluations of someone tracking another person's possessions, young children expressed positive evaluations of this behavior. These divergent moral judgments of digital tracking at different ages have profound implications for how concepts of digital privacy develop and for the digital security of children. 相似文献

Young children's sensitivity and responsiveness to mothers' needs were investigated under conditions of high and low parenting risk (depressed and nondepressed mothers, SADS-L). Child characteristics of gender, affect, and impulse control problems and the mother-child attachment relationship were examined as they related to children's caring actions. Children's caring behavior was observed in an experimental situation in which their mothers simulated sadness and in a naturalistic setting. Attachment alone and child's problems alone were not predictors, and maternal diagnosis alone was not a strong predictor. Girls were significantly more caring than boys. Severe maternal depression was necessary to bring out high levels of responding in boys. Highest frequencies of caring were from children with severely depressed mothers, problems of affect regulation, and secure attachment. The importance of recognizing interacting influences and diverse underlying processes in the development of children's caring behavior is discussed. 相似文献

Many regions of the European Union with a high degree of autonomy have elected very clearly to stimulate scientific research and technological development (R&D) as a specific means of promoting economic growth and the welfare of their citizens. In Spain, several autonomous regions have organised their efforts in science and technology by means of the adoption of regional R&D plans. In some cases, particular concern is taken to link the scope of scientific research with that of technology, but even in these few cases, it is acknowledged that little is known of the mechanisms by which the results of scientific research are translated into technological development, and how this latter in turn influences the objectives of scientific research. Our aim in this article is to study in greater depth the relationship between science and technological development in the various regions of Spain. The methodology that we apply to investigate the links between science and technology is based on an analysis of scientific citations in patent documents (non-patent citation (NPC)). The results obtained from this study provide some relevant data on the interconnection between the scientific and technological systems from a regional perspective. 相似文献

Many studies have shown that students of all school levels hold alternative conceptions that differ from the scientific conceptions transmitted by the school. These results raise some questions about the efficacy of traditional teaching and stress the need for using teaching strategies that explicitly take into account the alternative conceptions that students bring to the science classes. This issue has recently been raised and widely discussed throughout Portugal and the proposals for the new science syllabuses advise teachers to take it into account. However, the number of studies investigating both the teachers' attitudes towards this issue and the use of teaching strategies based on students' alternative conceptions is very limited. This article aims to present the results obtained from science teachers about their attitudes towards students' alternative conceptions and the use of teaching strategies based on these conceptions. The results may contribute to the planning of in-service courses. 相似文献

The article focuses on the financial issues and family background of Erasmus students. It examines the costs of Erasmus study periods in the academic year 2004/05 and the socio-economic background of Erasmus students that year, based on over 15000 survey responses. Results are compared with those of a similar survey undertaken in 1998 to track changes over the last decade. The main question that the article addresses is whether international mobility of higher education students within the Erasmus programme has been expanded to more students from lower socio-economic backgrounds during this period. We find that, in spite of still important socio-economic barriers to the take-up of the programme, access has been moderately widened. 相似文献

Children need to learn to persist through challenges, yet adults sometimes step in to solve problems for them. Here, we looked at how adult taking over related to children’s persistence. In an observational study (N = 34, ages 4–8), we found that parents who took over more often during a challenging puzzle task rated their children as dispositionally less persistent. To establish whether taking over can cause reduced persistence, we ran two preregistered experiments (N = 150, ages 4–5). Children assigned to a taking over condition persisted less on a subsequent task compared to those in a teaching or a baseline condition. Reframing the context did not ameliorate the negative impact of taking over. The results suggest that taking over impairs children’s persistence. 相似文献

Research on classroom peer effects has focused nearly exclusively on high-income countries and on academic skills. Little is known about peer effects in low-income countries and whether effects differ under different educational environments (e.g., teacher-directed versus child-centered, conditions of concentrated advantage or disadvantage). Based on a data set of Ghanaian preprimary classrooms in the Greater Accra Region collected in the 2015–2016 school year, we use complex system networks with multilevel modeling to study the presence and magnitude of peer effects. Results corroborated small statistically significant effects on academic and nonacademic skills (d = .06–.10). Peer effects on literacy were larger for children in public schools, who are relatively more disadvantaged than their private school counterparts. Teacher-directivity intensity did not moderate peer effects. 相似文献

This paper examines majority (white) and minority faculty perceptions in academe. It focuses on two general areas of institutional activity: employment and workplace issues, and minority affairs. The data examined in this paper are from a study of faculty at the University of Colorado (CU) system. The faculty sample in this study consisted of 73 minority faculty and 122 majority faculty. The findings reported in this paper show that minority faculty are dissatisfied with certain contexts within the post-secondary education institution, and minority faculty feel excluded from others. Discussion in this paper examines the interaction of status (majority vs. minority) and gender with perceptions of the postsecondary education institution. 相似文献

This paper presents findings about the images of science drawn upon in laboratory work, by upper secondary and university students, in academic streams with a science focus. Data were collected through four written questions, administered to a total of 368 students. The questions all required students to comment on laboratory investigations carried out by research scientists or by science students. We show that students' reasoning has an epistemological and an ontological dimension, and that it often differs significantly from accepted perspectives on the nature of science. The issue for teaching appears to be showing students what counts (and what does not count) as appropriate reasoning in actual situations. In other words, explicit teaching about the various relationships that can exist between theory and data would transform labwork towards a more critical process that involves making and justifying decisions. 相似文献

The objective of this study was to evaluate the efficacy of a multicomponent program for treating attention-deficit/hyperactivity disorder (ADHD) carried out by teachers in a classroom context. Dependent measures included neuropsychological tasks, behavioral rating scales for parents and teachers, direct observation of behavior in the classroom, and academic records of children with ADHD. Fifty children with ADHD participated in the study. The teachers of 29 of the 50 students were trained in the use of behavior modification techniques, cognitive behavior strategies, and instructional management strategies. The other 21 students formed the control group. Parents' and teachers'ratings detected improvements in primary symptoms (inattention-disorganization, hyperactivity-impulsivity) and in behavioral difficulties usually associated with ADHD (e.g., antisocial behavior, psychopathological disorders, anxiety). Furthermore, the results showed increased academic scores, enhanced classroom behavioral observations, and improved teachers' knowledge about the strategies directed toward responding to the children's educational needs. 相似文献
