Converging evidence from a number of neuroimaging studies, including our own, suggest that fluent word identification in reading is related to the functional integrity of two left hemisphere posterior systems: a temporo-parietal system and a ventral occipito-temporal system. These posterior systems are functionally disrupted in developmental dyslexia. Reading disabled, relative to nonimpaired, readers demonstrate heightened reliance on both inferior frontal and right hemisphere posterior regions, presumably in compensation for the LH posterior difficulties. We propose a neurobiological account suggesting that for normally developing readers the temporo-parietal system predominates at first, and is associated with aspects of processing critical in learning to integrate orthography with phonological and lexical-semantic features of printed words. The occipito-temporal system, by contrast, constitutes a fast, late-developing, word-identification system that underlies fluent word recognition in skilled readers.  相似文献   

Learning through work: Exploring instances of relational interdependencies     

Stephen Billett 《International Journal of Educational Research》2008,47(4):232-240

This paper provides an account of the inter-psychological processes that constitute learning through work. It does this by drawing on deliberations about the relative contributions of the immediate social world (i.e., workplace setting) that individuals encounter and the personal premises for individuals’ learning. This account is realised through analyses of workers’ experiences of working and learning in both large and small enterprises. Together, these premises and their contributions are used to elaborate how learning through work proceeds as a process of relational interdependence between the affordance of the workplace and the engagement of workers. This relational process is evident in work of different kinds, from the labours of coalminers through to the entrepreneurial activities of small business operators. Instances of learning through work are elaborated through studies that identify how workplaces’ affordances—those that invite workers in particular ways to participate, access support and reward—are generated and projected. These contributions to engaging in and learning through work can be conceptualised as the immediate social contribution or experience that is shaped by cultural and situational factors and the social legacies that shape how individuals construe, engage in, and learn through those practices. It concludes by discussing issues related to both the inter-psychological process and outcomes (e.g., inter-subjectivity) arising from learning through work.  相似文献

Children’s rights in education research: from aims to outcomes     

Hilary A. Smith  Stephen J. Haslett 《Cambridge Journal of Education》2017,47(3):413-438

One approach to children’s rights in research is to adopt a methodology that focuses on eliciting children’s perspectives. Ensuring representative participation from all children allows a diversity of contexts to be reflected in the results, and points to ways in which improvements can be made in specific settings. In cultural contexts where participation in decision-making is not a traditional role for children, their viewpoints are likely to provide results that highlight differences between cultural norms and children’s rights, and can offer an important focus of dialogue among stakeholders. It is proposed that children’s rights can therefore become integral to the whole process of a quantitative research project. This paper describes such an approach used in a Pacific Islands study, which investigated the quality of schooling through a probability-based sample survey of 1560 children in the first three years of formal education in 55 schools in Vanuatu, the Solomon Islands and Kiribati.  相似文献   

Off line simulation system of machining processes     

Ibrahim M. Deiab  Stephen C. Veldhuis 《Journal of The Franklin Institute》2007,344(5):565-576

The primary objective for modeling of machining processes is to develop a predictive capability of machining performance in order to facilitate effective planning of machining operations. This capability leads to faster implementation, higher performance, quality at a lower cost. This comes about due to improved selection of machining parameters, optimal fixture design and the avoidance of tool failure. The simulation system presented simultaneously considers the effect of cutter geometry, the cutter's initial position errors, workpiece geometry, machine tool dynamics, and workpiece/fixture system dynamics on the machining process.The integration of all of the above in one model provides an off-line tool to simulate and optimize the machining parameters and the fixture configuration cutting both lead and production time. The modular nature of the simulation system presented allows for the study of many different machining processes. The cutting forces in this system are modeled using a mechanistic approach. NURBS curves and surfaces are utilized for the geometric modeling and simulation of the machining process. While a finite element method is used to model and analyze the workpiece/fixture dynamics. Two case studies are presented to demonstrate the practical application of the presented simulation. The first case presents the optimization of the fixture configuration of a generic automotive component. While the second case presents the results of simulations performed on a novel mill/grind machining process. This process is a combination of face milling and grinding in one operation. Some simulated results are presented along with experimental validation.  相似文献   

The effect of use and access on citations

It has been shown (Lawrence, S. (2001). Online or invisible? Nature, 411, 521) that journal articles which have been posted without charge on the internet are more heavily cited than those which have not been. Using data from the NASA Astrophysics Data System (ads.harvard.edu) and from the ArXiv e-print archive at Cornell University (arXiv.org) we examine the causes of this effect.  相似文献

SimPharm: How pharmacy students made meaning of a clinical case differently in paper‐ and simulation‐based workshops     

Swee‐Kin Loke  June Tordoff  Michael Winikoff  Jenny McDonald  Peter Vlugter  Stephen Duffull 《British journal of educational technology : journal of the Council for Educational Technology》2011,42(5):865-874

Several scholars contend that learning with computer games and simulations results in students thinking more like professionals. Bearing this goal in mind, we investigated how a group of pharmacy students learnt with an in‐house developed computer simulation, SimPharm. Adopting situated cognition as our theoretical lens, we conducted a case study involving 20 undergraduate students to tease out how they made meaning of a clinical case differently in two different contexts: a typical paper‐based workshop and one enabled by SimPharm. The data collected included audio recordings of classroom discourse, focus group interviews and class observations. The findings identified differences in four areas: framing of the problem; problem‐solving steps and tools used; sources and meaning of feedback; and conceptualisation of the patient. These four areas can serve as axes along which future evaluations of educational simulations can be carried out based on their affordances.  相似文献   

School quality, child wellbeing and parents’ satisfaction   总被引：1，自引：0，他引：1  

Stephen Gibbons  Olmo Silva 《Economics of Education Review》2011,30(2):312-331

Child wellbeing at school and enjoyment of the learning environment are important economic outcomes, in particular because a growing body of research shows they are strongly linked to later educational attainments and labour market success. However, the standard working assumption in the economics of education is that parents choose schools on the basis of test-score performance, and concerns about child happiness are largely ignored. In this paper, we address this omission and investigate to what extent parents’ and children's views of their school are linked to test-score based performance, and to what extent parents’ judgements of school quality are linked to their child's happiness. To do so, we use information on stated attitudes from the Longitudinal Survey of Young People in England (LSYPE) matched to administrative records on pupil achievements in England. Our results suggest that test-score based measures of school quality tend to dominate parental satisfaction with the learning environment. However, school quality along this dimension is not strongly associated with pupil happiness and wellbeing at school.  相似文献
