In Norway more than 95 per cent of the students in each annual school-leaving cohort from the lower secondary school continue on to upper secondary education. The result is that there is a wide range of abilities among the students, and so various forms of adapted teaching are necessary. Each year almost 10 per cent of the new entrants in upper secondary are classified as students with special needs. The main focus of this paper is on how different forms of adaptation influence the flow of special needs students through upper secondary education. Two groups are compared: one with students who in their first year are taught exclusively within ordinary classes, and one with students who receive adapted teaching in small groups outside ordinary classes. The analysis controls for the level of functional difficulties among the students. The study illuminates how the organization of the specially adapted teaching influences successes as well as failures among the students. A sample of special needs students from six Norwegian counties has been followed prospectively through upper secondary education. Results of this follow-up study are presented within a theoretical framework based on transitions in the life course. 相似文献

Test fairness and test bias are not synonymous concepts. Test bias refers to statistical evidence that the psychometrics or interpretation of test scores depend on group membership, such as gender or race, when such differences are not expected. A test that is grossly biased may be judged to be unfair, but test fairness concerns the broader, more subjective evaluation of assessment outcomes from perspectives of social justice. Thus, the determination of test fairness is not solely a matter of statistics, but statistical evidence is important when evaluating test fairness. This work introduces the use of the structural equation modelling technique of multiple-group confirmatory factor analysis (MGCFA) to evaluate hypotheses of measurement invariance, or whether a set of observed variables measures the same factors with the same precision over different populations. An example of testing for measurement invariance with MGCFA in an actual, downloadable data set is also demonstrated. 相似文献

Science and the diffusion of knowledge 总被引:2,自引:0,他引:2
Scientists, social scientists and politicians frequently credit basic science with stimulating technological innovation, and with it economic growth. Despite a substantial body of research investigating this general relationship, relatively little empirical attention has been given to understanding the mechanisms that might generate this linkage. This paper considers whether more rapid diffusion of knowledge, brought about by the norm of publication, might account for part of this effect. We identify the importance of publication by comparing the patterns of citations from future patents to three groups of focal patents: (i) those that reference scientific (peer-reviewed) publications, (ii) those that reference commercial (non-scientific) publications; and (iii) those that reference neither. Our analyses strongly implicate publication as an important mechanism for accelerating the rate of technological innovation: Patents that reference published material, whether peer-reviewed or not, receive more citations, primarily because their influence diffuses faster in time and space. 相似文献

Complexity, networks and knowledge flow 总被引:7,自引:0,他引:7
Because knowledge plays an important role in the creation of wealth, economic actors often wish to skew the flow of knowledge in their favor. We ask, when will an actor socially close to the source of some knowledge have the greatest advantage over distant actors in receiving and building on the knowledge? Marrying a social network perspective with a view of knowledge transfer as a search process, we argue that the value of social proximity to the knowledge source depends crucially on the nature of the knowledge at hand. Simple knowledge diffuses equally to close and distant actors because distant recipients with poor connections to the source of the knowledge can compensate for their limited access by means of unaided local search. Complex knowledge resists diffusion even within the social circles in which it originated. With knowledge of moderate complexity, however, high-fidelity transmission along social networks combined with local search allows socially proximate recipients to receive and extend knowledge generated elsewhere, while interdependencies stymie more distant recipients who rely heavily on unaided search. To test this hypothesis, we examine patent data and compare citation rates across proximate and distant actors on three dimensions: (1) the inventor collaboration network; (2) firm membership; and (3) geography. We find robust support for the proposition that socially proximate actors have the greatest advantage over distant actors for knowledge of moderate complexity. We discuss the implications of our findings for the distribution of intra-industry profits, the geographic agglomeration of industries, the design of social networks within firms, and the modularization of technologies. 相似文献

Abundant research exists on the transition from school to work of youth with disabilities. However, few studies investigate their subsequent long-term participation in working life. This study, drawing on a life course approach, aimed to examine how former students with special educational needs succeeded in finding full-time employment with sufficient pay to make them economically independent. The extent of economic independence was investigated in their late twenties and their mid-thirties. The sample (N?=?216) originates from a Norwegian longitudinal research project that commenced in the mid-1990s when the study participants just had started upper secondary school. Their special needs provision and their physical, psychological and/or social difficulties were recorded at the same time. After their teens, they were interviewed every fifth year. At both age phases close to 50% of the study participants were economically independent, men to a much greater degree than women. By logistic regression analyses, it was revealed that the independent variables influenced economic independence differently among men and women, for example, that educational attainment was important for women, but not for men. However, possession of a driving licence was crucial for men, but was relatively unimportant for women, at least in the first age phase. There was also a differential impact of parenthood. Having children increased the likelihood of being economically independent for men, whereas the impact was opposite for women, especially when they were approaching their mid-thirties. Processes of cumulative advantages and disadvantages were also observed, indicating that previous negative life course experiences dramatically reduce the chances of obtaining economic independence. 相似文献

Abstract This study investigates the effects on learning‐disabled students of embedding a drill and practice task within an arcade game‐like context. We identified 30 learning‐disabled and 30 nondisabled students who had conceptual understanding of addition but had not achieved automaticity in addition facts. We trained students on either a drill‐and‐practice game or an unadorned, straightforward drill (i.e., “plain vanilla") program. We assessed automaticity in three modes of responding—oral, computer keyboard, and written response. There was a significant interaction effect indicating that the learning‐disabled students were relatively disadvantaged by repeated practice in the game format. We infer learning‐disabled students' lower performance is attributed to attentional difficulties, particularly selective attention problems, when potentially distracting elements of a game environment are present. 相似文献

Abstract The growth in importance of performance assessment in education over recent years has been linked with a concern to ensure that the service represents ‘value for money’. To date the absence of a satisfactory analytical framework has meant that questions of ‘effectiveness’ and ‘efficiency’ have been kept separate. An additional problem has been that, whilst there are many different outcomes which are appropriate for education authorities to pursue, conventional models handle these only one at a time. In this paper we use data on the 96 English LEAs to show how an underlying model allows authorities to be compared in terms of ‘efficiency’ when facing different environmental circumstances and utilising different resource inputs. The technique of Data Envelopment Analysis (DEA) is first described in the context of an explanatory model, and then the results of applying this to the English LEAs are presented. As distinct from a league table’ analysis, DEA gives some indications of where improvements are to be sought. It allows for ‘trade‐offs’ between outputs of different types and provides a small but distinct peer group of ‘efficient’ authorities to which an ‘inefficient’ LEA can be compared. The efficiency measure used is ‘relative efficiency’ which arises from comparing the actual performance of an inefficient authority with that of others which can be used to model its environmental circumstances and resource inputs. A number of case studies are described. The limitations of the technique, and the caution required in interpretation, are discussed. 相似文献

A Mediational Model of the Impact of Marital Conflict on Adolescent Adjustment in Intact and Divorced Families: The Role of Disrupted Parenting 总被引:7,自引:0,他引:7
Robert Fauber Rex Forehand Amanda McCombs Thomas Michelle Wierson 《Child development》1990,61(4):1112-1123
The present study was concerned with the development and testing of a structural equation model wherein the relation of interparental conflict to the adjustment problems of young adolescents is mediated through its impact on 3 aspects of parenting behavior: lax control, psychological control, and parental rejection/withdrawal. The model was tested separately on a sample of 46 young adolescents from intact families and a group of 51 adolescents from recently divorced families. The hypothesis that most of the relation between martial conflict and adolescent adjustment problems could be explained through perturbations in the parent-child relationship received considerable support; the only direct effect of conflict was on externalizing problems in the intact sample. The results also suggested that the mediational patterns were somewhat different for the 2 samples, and that the model accounts for a greater proportion of the variance in the adjustment problems of adolescents from intact homes than of those from recently divorced families. 相似文献
