Bernstein and the explanation of social disparities in education: a realist critique of the socio‐linguistic thesis     

Roy Nash 《British Journal of Sociology of Education》2006,27(5):539-553

Can an explanation of the origins of social disparities in educational achievement be assisted by a critical examination of Bernstein’s sociology? This central question is approached by a consideration of the status of Bernstein’s socio‐linguistic thesis. The focus is on the nature of the explanations provided. The paper asks: What is the explanatory force of Bernstein’s structuralism? What is the relationship between Bernstein’s sociological explanations and Vygotskian psychological explanations? What are the effects for pedagogy of cognitive socialization mediated by language‐use consistent with Bernstein’s theory? The answers to these questions may pose a challenge for sociologists of education engaged with Bernstein’s sociology.  相似文献   

Assessing Model Similarity in Structural Equation Modeling     

Keke Lai  Samuel B. Green  Roy Levy  Ray E. Reichenberg  Yuning Xu  Marilyn S. Thompson 《Structural equation modeling》2016,23(4):491-506

Two models can be nonequivalent, but fit very similarly across a wide range of data sets. These near-equivalent models, like equivalent models, should be considered rival explanations for results of a study if they represent plausible explanations for the phenomenon of interest. Prior to conducting a study, researchers should evaluate plausible models that are alternatives to those hypothesized to evaluate whether they are near-equivalent or equivalent and, in so doing, address the adequacy of the study’s methodology. To assess the extent to which alternative models for a study are empirically distinguishable, we propose 5 indexes that quantify the degree of similarity in fit between 2 models across a specified universe of data sets. These indexes compare either the maximum likelihood fit function values or the residual covariance matrices of models. Illustrations are provided to support interpretations of these similarity indexes.  相似文献   

Sex differences in the missing-letter effect: A question of reading or visual–spatial skills?     

Jean Saint-Aubin  Daniel Voyer  Macha Roy 《Learning and individual differences》2012,22(6):664-672

When readers must search for a target letter while reading a continuous text, they are more likely to miss targets in frequent function words than in less frequent content words. This missing-letter effect has been found across many languages, methodologies, and types of reading materials. Despite the ubiquity of the missing-letter effect, sex differences have been reported, but their pattern is conflicting and no clear interpretation has been offered so far. In two experiments, sex differences were examined in the letter search task, while also measuring spatial and reading skills. In both experiments, the missing-letter effect was found for both genders and a larger missing-letter effect was found for faster readers. It is concluded that when sex differences are observed in the missing-letter effect, they are likely due to reading speed and not to spatial skills as previously hypothesized. Results are interpreted in light of the Attentional Disengagement model of the missing-letter effect.  相似文献   

Enrico Fermi — The complete physicist     

Amit Roy 《Resonance》2014,19(8):684-703

Enrico Fermi was a versatile physicist contributing in equal measure to theory and experiments. He is credited to be the ‘Father of the Atomic Age’ following his successful demonstration of sustained chain reaction in Chicago Pile-1. In this article, I have discussed his major experimental contributions that clearly demonstrate his simplicity of conception, meticulous attention to detail and directness of approach to the problem at hand.  相似文献   

Projectile motion with quadratic damping in a constant gravitational field     

Chandra Das  Dhiranjan Roy 《Resonance》2014,19(5):446-465

The motion of a projectile in a constant gravitational field is an age-old problem. If there is no resistive force, the problem is simple. However, with the intoduction of resistive forces, the complexity of the problem increases. Recently, there has been a growing interest in the problem of projectile motion under a resistive force proportional to the square of velocity. The problem for resistive force proportional to vv cannot be solved in closed analytical form. A series solution of the equation leads to divergent series for x (t) and y (t) for reasonable values of the initial speed and angle of projection. However, we demonstrate that by inverting the series for x (t), i.e., expressing t in terms of x, and substituting this in y (t) one can express y in terms of x which is a highly convergent series and one can obtain the path of projectile with a few terms of the series. We further demonstrate that one can obtain the path even with a few terms of the divergent series for x (t) and y (t) by using extrapolation methods.  相似文献

Studying School Architecture: some reflections     

Roy Lowe 《International Journal of Research & Method in Education》2013,36(1):45-52

Abstract

This article reports on the findings of an investigation in which 30 secondary schools rated the priority being given to and the likely impact on teaching and learning of a selection of 23 issues currently on the agenda for school improvement. Results are considered for the whole sample, and according to the role of respondents and school context. Schools are giving high priority to the implementation of national policies and school‐generated initiatives directed at improved classroom practice. However, the perceived impact of externally generated change is less than that of change for which school staff feel a sense of ownership. Policies directed at a consideration of resource issues, professional development and salary changes are accorded low priority and are not considered to have a marked impact on teaching and learning. There is a potential for frustration and loss of morale when policies that are thought to be of limited value within schools require time and sometimes extensive consideration. The article's conclusions for policy‐makers are directed at minimising this risk.  相似文献
