通过对单向冷轧的纯铝板在140℃，200℃，300℃，380℃退火，用X射线衍射物相分析，研究冷轧纯铝板在退火前和各温度退火后的织构，结果表明，在140－300℃的中低温退火后，板中的形变强织构被削弱，产生新的退火织构；在380℃的高温退火后，板中的形变强织构被进一步增强。  相似文献   

Word stress production in three‐year‐old children at risk of dyslexia     

Elise De Bree  Frank Wijnen  Wim Zonneveld 《Journal of Research in Reading》2006,29(3):304-317

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   

Power,Perceptions, and Relationships: A Model of Co-Teaching in Higher Education     

John R. Morelock  Marlena McGlothlin Lester  Michelle D. Klopfer  Alex M. Jardon  Ricky D. Mullins  Erika L. Nicholas 《College Teaching》2017,65(4):182-191

Co-teaching has historically been used in K–12 education to provide students with disabilities access to general curriculum; therefore, much of the co-teaching literature has focused on the K–12 population. Research on collegiate co-teaching has been more limited and largely focused on the advantages and disadvantages of co-teaching, omitting important factors that affect relationships between partners. This qualitative study involved seven interviews of co-teachers of graduate and undergraduate classes in order to better understand interactions between college-level co-teaching dyads. Data analysis revealed themes of power and authority structures, dynamics of co-teaching relationships, and co-teachers' perceptions related to advantages of co-teaching, disadvantages of co-teaching, and student experiences. The researchers developed the Circular Model of Collegiate Co-Teaching, an original model to explain how these themes and subthemes are interrelated and affect each other. Specific best practices and new insights for collegiate co-teaching practice are discussed.  相似文献

The effect of language specific factors on early written composition: the role of spelling,oral language and text generation skills in a shallow orthography     

Barbara Arfé  Julie E. Dockrell  Bianca De Bernardi 《Reading and writing》2016,29(3):501-527

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   

Towards powerful learning environments for the acquisition of problem-solving skills     

Erik De Corte 《European Journal of Psychology of Education - EJPE》1990,5(1):5-19

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
