Infants require locomotor experience to behave adaptively at a drop‐off. However, different experimental paradigms (visual cliff and actual gaps and slopes) have generated conflicting findings regarding what infants learn and the specificity of their learning. An actual, adjustable drop‐off apparatus was used to investigate whether learning to distinguish a step from a cliff transfers from crawling to walking. Experienced 12‐month‐old crawlers (n = 16) refused to crawl over risky drop‐offs but novice 12‐month‐old walkers (n = 17) stepped repeatedly over the edge. Experienced 18‐month‐old walkers (n = 18) refused to walk over risky drop‐offs but descended using alternative methods. These findings suggest that infants do not acquire generalized responses like fear or wariness of heights. Rather, infants learn to perceive affordances for the experienced action. 相似文献

For over a decade, all three‐year‐olds in England have been entitled to a free part‐time early education place. One aim of this policy is to close developmental gaps between higher‐income and low‐income children. However, the success of the initiative depends on children accessing the places. Using the National Pupil Database, we examine all autumn‐born four‐year‐olds attending in January 2011, and ask whether they started attending when first eligible, in January 2010. One in five children did not access their free place from the beginning, and the proportion is much higher among children from families with persistently low incomes. We also find differences by ethnicity and home language, but these factors explain only a small share of the income gradient. We go on to explore associations between non‐take‐up and local area factors. In areas with higher child poverty rates, take‐up is lower overall, but the gap between low‐income and other families is smaller. There are also various associations between take‐up and local proportions of different provider types (maintained, private, voluntary, Sure Start). In particular, the voluntary sector seems to have more flexibility than maintained provision to offer places in January, and more success than private providers in reaching children from lower‐income backgrounds. The analysis also highlights how take‐up overall is relatively high and the gap by income level is smaller in areas with more Sure Start provision. This suggests that aspects of Sure Start facilitated access among low‐income families, and could perhaps be replicated as implementation of the free entitlement continues to be expanded. 相似文献

Do Parents Foster Self‐Esteem? Testing the Prospective Impact of Parent Closeness on Adolescent Self‐Esteem 下载免费PDF全文

Close parent–child relationships are viewed as important for the development of global self‐esteem. Cross‐sectional research supports this hypothesis, but longitudinal studies provide inconsistent prospective effects. The current study uses data from Germany (N = 982) and the United States (N = 451) to test longitudinal relations between parent–child closeness and adolescent self‐esteem. The authors used self‐, parent‐, and observer‐reported parent–child closeness and self‐reported self‐esteem from ages 12 to 16. Results replicated concurrent correlations found in the literature, but six longitudinal models failed to show prospective relations. Thus, the longitudinal effect of parent–child closeness and self‐esteem is difficult to detect with adolescent samples. These findings suggest the need for additional theorizing about influences on adolescent self‐esteem development and longitudinal research with younger samples. 相似文献

An ‘at‐risk’ curriculum for ‘at‐risk’ students? Special educational needs and disability in the new Australian Curriculum 下载免费PDF全文
下载免费PDF全文 The number of students who are ‘at risk’ including those with special education needs and or disabilities is increasing rapidly worldwide in all schools. This has prompted widespread debate regarding the impact of initiatives in Curriculum, Assessment and Reporting for this group of students. Teachers, parents and administrators need to have further information to enable them to contribute to the development of content, assessment and reporting processes in the curriculum that are inclusive, relevant, reliable and valid. This paper explores some of the issues and dilemmas raised by recent policy discussions regarding the inception of a first national Australian Curriculum. It draws purposively on literature relating to developments in England and Wales, where national curriculum provision has existed for over 25 years, as well as the responses of a group of stakeholders (teachers and leaders) from both England/Wales and Australian schools and settings. These data highlight both tension and opportunity in this area of work. 相似文献

A natural language based system has been used to author and mark short-answer free-text assessment tasks. Students attempt the questions online and are given tailored and relatively detailed feedback on incorrect and incomplete responses, and have the opportunity to repeat the task immediately so as to learn from the feedback provided. The answer matching has been developed in the light of student responses to the questions. A small number of the questions are now in low-stakes summative use, alongside other e-assessment tasks and tutor-marked assignments, to give students instantaneous feedback on constructed response items, to help them to monitor their progress and to encourage dialogue with their tutor. The answer matching has been demonstrated to be of similar or greater accuracy than specialist human markers. Students have been observed attempting the questions and have been seen to respond in differing ways to both the questions themselves and the feedback provided. We discuss features of appropriate items for assessment of this type. 相似文献

This study investigated the development of all 3 components of episodic memory (EM), as defined by Tulving, namely, core factual content, spatial context, and temporal context. To this end, a novel, ecologically valid test was administered to 109 participants aged 4-16 years. Results showed that each EM component develops at a different rate. Ability to memorize factual content emerges early, whereas context retrieval abilities continue to improve until adolescence, due to persistent encoding difficulties (isolated by comparing results on free recall and recognition tasks). Exploration of links with other cognitive functions revealed that short-term feature-binding abilities contribute to all EM components, and executive functions to temporal and spatial context, although ability to memorize temporal context is predicted mainly by age. 相似文献

Many theories have been proposed to help instructional designers make instructional‐strategy decisions, yet it is not clear if these theories are actually used by ID practitioners. This study used a web‐survey to examine the design strategies of 113 ID practitioners. The survey asked respondents to rate how frequently they used learning or ID theories as well as 10 other design strategies, to help make instructional‐strategy decisions. Respondents were also asked how often they used different information sources to learn about new theories, trends, and strategies, and to respond to a set of contrasting statements depicting objectivist vs. construc‐tivist assumptions. The results indicate that ID practitioners most often rely on interaction with others both as a means of making instructional‐strategy decisions and of learning about new theories, trends, and strategies. Only fifty percent of the respondents said they regularly use theories when making instructional‐strategy decisions, using other design strategies more frequently instead; and most practitioners are eclectic in their underlying philosophical assumptions. Based on these results, we discuss implications for training and ongoing support of instructional designers. 相似文献

Inequality in language achievement growth? An investigation into the impact of pupil socio‐ethnic background and school socio‐ethnic composition 下载免费PDF全文

This paper investigates how pupils' growth trajectories in three language domains (reading fluency, spelling, and reading comprehension) are related to their own socioeconomic and ethnic background and to the socioeconomic and ethnic composition of their primary school. Using multilevel piecewise growth curve analysis, the growth trajectories of approximately 5000 pupils from 170 primary schools were estimated. The results indicate that a pupil's socioeconomic and ethnic backgrounds have the largest impact on achievement and growth in reading comprehension and the smallest impact on reading fluency. Furthermore, school ethnic composition—but not socioeconomic composition—was related to pupils' achievement in all three language domains at the first measurement occasion, though none of the types of school composition was related to growth. The research findings therefore imply that to combat the deficits in language proficiency often found in ethnic minority pupils, priority should be given to investments in individual intervention programmes over policy plans to desegregate schools. Moreover, our study identifies the specific points in time during primary school at which intervention programmes are needed the most. 相似文献

The current study estimated the causal links between preschool mathematics learning and late elementary school mathematics achievement using variation in treatment assignment to an early mathematics intervention as an instrument for preschool mathematics change. Estimates indicate (n = 410) that a standard deviation of intervention‐produced change at age 4 is associated with a 0.24‐SD gain in achievement in late elementary school. This impact is approximately half the size of the association produced by correlational models relating later achievement to preschool math change, and is approximately 35% smaller than the effect reported by highly controlled ordinary least squares (OLS) regression models (Claessens et al., 2009; Watts et al., 2014 ) using national data sets. Implications for developmental theory and practice are discussed. 相似文献

The process of learning new surgical technical skills is vital to the career of a surgeon. The acquisition of these new skills is influenced greatly by visual‐spatial ability (VSA) and may be difficult for some learners to rapidly assimilate. In many cases, the role of VSA on the acquisition of a novel technical skill has been explored; however, none have probed the impact of a three‐dimensional (3D) video learning module on the acquisition of new surgical skills. The first aim of this study is to capture spatially complex surgical translational flaps using 3D videography and incorporate the footage into a self‐contained e‐learning module designed in line with the principles of cognitive load theory. The second aim is to assess the efficacy of 3D video as a medium to support the acquisition of complex surgical skills in novice surgeons as evaluated using a global ratings scale. It is hypothesized that the addition of depth in 3D viewing will augment the learner's innate visual spatial abilities, thereby enhancing skill acquisition compared to two‐dimensional viewing of the same procedure. Despite growing literature suggesting that 3D correlates directly to enhanced skill acquisition, this study did not differentiate significant results contributing to increased surgical performance. This topic will continue to be explored using more sensitive scales of measurement and more complex “open procedures” capitalizing on the importance of depth perception in surgical manipulation.

Over a decade ago the UK government launched its gifted and talented education policy in England, yet there has been very little published research which considers how schools and teachers are interpreting and implementing the policy. By seeking the views of the gifted and talented co‐ordinators (For ease of reference, the term gifted and talented (G&T) co‐ordinator is used throughout the paper as a generic shorthand for the research participants who were either designated school gifted and talented co‐ordinators or teachers or head teachers with responsibility for policy implementation) with responsibility for addressing the requirements of the policy, the study reported in this paper explored how primary schools in England responded to the policy. Drawing on data gathered using questionnaires with a national sample of primary schools as well as follow‐up in‐depth interviews with a sample of G&T co‐ordinators, the authors report their findings. The study found that there was considerable unease about the concept of identifying and ‘labelling’ a group of pupils as ‘gifted and talented’. G&T co‐ordinators found it difficult to interpret the policy requirements and were responding pragmatically to what they considered to be required by the government. Curriculum provision for the selected group of gifted and talented pupils was patchy. The paper concludes by identifying a need for further professional development for teachers and by challenging the policy's over‐emphasis on identifying and labelling gifted and talented pupils. We posit whether the gifted and talented education policy would have been better introduced and enjoyed greater success by leaving the identification of pupils to one side and by placing greater emphasis on developing effective learning and teaching strategies instead. 相似文献

Based on contingency theory, this paper examines whether certain contextual conditions influence the effectiveness of HRD [human resource development] programs and activities. Stakeholders of two types of HRD programs who were also from companies in two economic sectors were asked to complete a questionnaire. No differences in perceived effectiveness was observed for the factors of size and structure of the company, economic sector, structure of the HRD function, and transfer conditions. Significant differences were found for the problem that serves as starting point for HRD—company HRD climate, position of the HRD department, and the form the HRD program takes. 相似文献

Spurred by recent writings regarding statistical pragmatism, we propose a simple, practical approach to introducing students to a new style of statistical thinking that models nature through the lens of data‐generating processes, not populations. 相似文献
