We investigated Dutch word stress acquisition in 3‐year‐old children at risk of dyslexia (children with at least one parent or older sibling with reading difficulties) and normally developing children, in order to shed light on language acquisition delays in children at risk of dyslexia, as well as to investigate further phonological deficits in dyslexia. The children had to repeat non‐words with stress patterns varying in regularity. Both the at‐risk and control children performed better on imitation of regular stress targets and worse on irregular and prohibited stress patterns. However, the at‐risk children showed more difficulty imitating irregular and prohibited patterns, and had lower percentages phonemes correct than the control group. The results can be interpreted as a delay in word stress acquisition in the at‐risk group. The findings thus point towards a phonological deficit early in language development.  相似文献

Spelling skills have been identified as one of the major barriers to written text production in young English writers. By contrast oral language skills and text generation have been found to be less influential in the texts produced by beginning writers. To date, our understanding of the role of spelling skills in transparent orthographies is limited. The current study addressed this gap by examining the contribution of spelling, oral language and text generation skills in written text production in Italian beginner writers. Eighty-three children aged 7–8 years participated in the study. Spelling, lexical retrieval, receptive grammar, and written sentence generation and reformulation skills were assessed and children were asked to write a text on a set topic. A factor analysis revealed that the children’s written text production was captured by three factors: productivity, complexity and accuracy. In contrast to results from children learning to write in opaque orthographies, such as English, this study showed that receptive grammar and written sentence generation skills accounted for significant variance in measures of productivity, complexity and accuracy in Italian children’s written text production. Spelling skills contributed to text accuracy and quality and explained more variance than receptive grammar in microstructural accuracy. By contrast, oral grammatical skills explained more variance in text quality than spelling. The current study shows the differential impact of language systems, such as Italian, on written text production. Implications for assessment and instruction are outlined.  相似文献

It is generally agreed that acquiring thinking and problem-solving skills is nowadays a primary objective of general education. Responding appropriately to this challenge requires an answer to the following questions: 1. what does the acquisition of problem-solving skills involve, and 2. how can those abilities be fostered through systematic instruction? This contribution describes a four-step model of skilled problem-solving processes, and gives an overview of three major categories of cognitive skills involved in competent problem solving, namely, the flexible and integrated application of domain-specific knowledge, of heuristic methods, and of metacognitive skills. Furthermore, a framework is presented for the design and elaboration of powerful teaching-learning environments in which such problem-solving skills can be acquired efficiently. Two basic ideas underlying this model are: the view of learning as a constructive process, and the idea of cognitive apprenticeship as an effective and appropriate method for learning and teaching. Finally, some recent research findings supporting the educational significance of the framework are briefly reviewed.  相似文献

This study examined the progress and disposition of child sexual abuse cases referred for prosecution in four urban jurisdictions. Most cases were accepted for prosecution. The vast majority of cases carried forward for prosecution resulted in guilty pleas. Only 9% of the total sample went to trial. A majority of the small number that went to trial were convicted. Over 3/4 of those convicted were incarcerated. The rate at which cases were carried forward for prosecution and convicted was comparable to that of a national sample of felony arrests overall, but child sexual abuse cases were more likely to go to trial (p < .005) and received more severe sentences (p < .005). Our results are strikingly consistent with those from previous studies of prosecution of child sexual abuse. A new understanding of prosecution of child sexual abuse is recommended that takes into account the large proportion of cases that do not go to trial.  相似文献

Since the turn of the century large groups of former institutionalised children have exercised their right to see their ‘personal files’, and this has drawn widespread attention to these documents and their potential in scholarly research. This article explores the meanings of personal files from the period 1945–1984 as sources for both historical researchers and adult care leavers themselves, in the context of the orphanages in Ghent, Belgium. Based on the experiences of those who have consulted their files, we come to the conclusion that the personal files of the Ghent orphans provide some new information but, at the same time, leave a lot of issues unresolved. Although the files offered significant insights for researchers studying the most recent period in the history of the Ghent orphanages, it is difficult to see them as ‘keys to the past’ for former orphans who are trying to (re)construct their own, individual life histories.  相似文献

This article considers the transmission of knowledge in higher education. It takes the metaphor of the music industry that pre‐selects the music people can buy. The sales potential is the leading principle in the selection process. Often the small producer is excluded because his or her music is not of commercial interest. The end‐customer does not know what he or she is missing because he or she has never heard the music. It is to be feared that a similar market principle will also influence the selection of knowledge and affect the capacity of higher education institutions to freely generate and transmit new knowledge. The globalization of higher education risks homogenizing the cultural traditions of the non‐Western world through a process of Western cultural domination. On the other hand, the Internet, via open source software like LINUX, might serve to democratize higher education and allow greater grassroots input.  相似文献
