新课程改革给教师提供了新的环境,新的发展空间,也给教师提出了更高的要求和更严峻的挑战。教师作为新课程改革的主体和关键,能否深入地实施新课程,将直接关系到新课程改革的可持续发展。新课改背景下教师地位、学生地位、教学评价、教学策略等因素决定了新课改中教师角色转换的必要性,教师角色必须转变,在教学活动中要真正体现“以学生为主体”,进行教育理念的创新与突破。 相似文献

Substantial research has detailed the reading deficits experienced by children with Duchenne muscular dystrophy (DMD). Although phonological awareness (PA) is vital in reading development, little is known about PA in the DMD population. This pilot study describes the PA abilities of a group of five young children with DMD, comparing the results with those of a group of children with spinal muscular atrophy and with those of a group of typically developing children. The Preschool and Primary Inventory of Phonological Awareness was used to assess the PA skills of the participants. Results indicated that the children with DMD performed significantly poorer than the typically developing group on tests of Syllable Segmentation, Rhyme Awareness, Alliteration Awareness and Phoneme Isolation and significantly poorer than the spinal muscular atrophy group on Rhyme Awareness. The findings of this pilot study indicate that children with DMD may have an increased risk of having PA difficulties, thus requiring early PA training. 相似文献

This study investigates the relationship between working memory and language in young children growing up in a multilingual environment. The aim is to explore whether mechanisms of short-term storage and cognitive control hold similar relations to emerging language skills and to investigate if potential links are mediated by related cognitive abilities. A sample of 119 Luxembourgish 6-year-olds completed several assessments of working memory (complex and simple span), native and foreign vocabulary, syntax, reading, rhyme awareness, and fluid intelligence. Results showed that short-term storage and cognitive control manifested differential links with developing language abilities: Whereas verbal short-term storage was specifically linked to vocabulary; cognitive control manifested unique and robust links with syntax and early reading development. The study suggests that in young children the working memory system is composed of separate but interacting components corresponding to short-term storage and cognitive control that can be distinguished by the roles they play in supporting language acquisition. 相似文献

Parkinson’s disease (PD) is a heterogenous disease caused by multifactorial etiology. PD is characterized by the loss of dopaminergic (DA) neurons in the substantia nigra and the accumulation of Lewy bodies. In this study, two Drosophila PD models by exposing Drosophila to rotenone (sporadic PD models) are proposed, and the human α-synuclein A30P protein (family PD models) in Drosophila is expressed respectively. Both models recapitulated the main human PD symptoms including the loss of dopaminergic neurons... 相似文献

力和力矩是两个不同的概念,应加以区别使用;肌肉工作时定点的确定要以躯体支撑点为基本参考点,肌肉做静力性工作时是双固定状态;肌肉拉力线应用射线来标示;要根据具体情况作具体分析,不能简单地以动点向定点的连线标示,影响肌肉最大力量的解剖学因素是该肌肉内可能形成的最大横桥数目和肌肉收缩时的初长度,神经调节、肌拉力角、肌收缩矩均不是影响肌肉最大比力的解剖学因素. 相似文献

This paper provides the opportunity to understand children’s behavior from a memory viewpoint. For the last three decades, cognitive developmentalists have been asking the question, “what develops in children’s memory?” Four answers to this question are presented, complete with explanations, examples, and possible applications where appropriate. The purpose of the paper is to provide early childhood educators and other practitioners who work with children a different lens through which to view children’s behavior. The memory view is compatible with current best practices in early childhood education, and may provide practitioners an additional viewpoint from which to draw when implementing developmentally appropriate practice. 相似文献

ABSTRACTThis paper challenges the notion that quantitative data – as a numeric truth – exist independent of a nation’s political and racial landscape. Utilising large-scale national attainment data, the analysis challenges the belief that ‘White working class’ children in England, especially boys, are ‘the new oppressed’ – as a former equality adviser has publicly claimed. The analysis applies Quantitative Critical Race Theory, or ‘QuantCrit’, an emerging quantitative sub-field of Critical Race Theory in education. The paper argues that far from being ‘oppressed’, White boys continue to enjoy achievement advantages over numerous minoritised groups; especially their peers of Black Caribbean ethnic origin. Additionally, the analysis uniquely exposes racialised trends of ‘equivalency’ in core subject qualifications, whereby minority ethnic children are over-represented in certain lower-status qualifications that are counted as equivalent in education statistics but not in the real world labour market. The analysis concludes that knowing misrepresentations of quantitative data are at the heart of an institutional process through which race and racism are produced, legitimised and perpetuated in education. 相似文献
