The implementation of inclusive practices in mainstream education remains particularly difficult in the French context and is influenced by various factors including the types of disability labels, and the type of assessment practices that are used. Indeed, how student disability is labelled could impact teacher attitudes by notably disfavouring students labelled with autism. Moreover, normative assessment is strongly linked with selection at schools—a function that works against teacher attitudes towards inclusive education. This article reports on a study in which we examined teacher intentions to use materials accommodated to special educational needs students, as a function of special needs labelling. Specifically, this refers to the use of labels for either a disability or special educational need, in connection to tasks associated with learning or assessment. The results of our study revealed that, for both types of labels, the intentions to use accommodated materials are lower when teachers are asked to assess student competence than when prompted to teach this competence. These findings are discussed with consideration to the incompatibility between selection in schools—which is aligned with the principle of meritocracy—and efforts to promote inclusive education practices. 相似文献

A sequence of tests on derived polynomials to be strictly Hurwitz polynomials is shown to be equivalent to a given (typically real) polynomial having all its zeros in an open sector, symmetric with respect to the real axis, in the left half-plane. The number of tests needed is at most 1 + ?(ln k)/(ln 3)?, where k is the integer associated with the central angle π/k of the sector. An extension of this result on the sector as a region of root clustering is given which shows that only a limited number of tests are needed to verify that the roots are clustered in a region composed as the intersection of a set of primative (sector-like) regions. The results reported evolve from application of a collection of mappings on the complex plane defined by a particular collection of Schwarz-Christoffel transformations. 相似文献

A study is made of the orthogonal polynomials on certain curves in the complex plane. Necessary and sufficient conditions for a set of polynomials to be orthogonal on the curves are obtained in terms of symmetric matrices. The relations of the symmetric matrices to Toeplitz matrices and innerwise matrices are shown. 相似文献

Heat effects in fixed-bed sorption columns are often quite large and have a pronounced effect on the sorption kinetics. Proper design of such systems must include consideration of these effects.A method is developed for computing the maximum possible bed temperature. The model is tested on two systems: (1) the Linde molecular sieve 4 A/water system and (2) the Alcoa activated alumina F-1/water system. Since the predicted temperatures appeared to be low for the latter system, the model was refined by the inclusion of the isosteric integral heat of adsorption. Tests on the activated alumina show considerable improvement.The isosteres of two sorption therm correlations are investigated. The results show that the heat of adsorption of water on the alumina varies logarithmically with sorbate concentration—approaching high values at low concentrations and approaching the heat of vaporization of water at high concentrations. The results also suggest that the isosteric heat of adsorption behavior may be of use in assessing the “goodness of fit” of sorption therm correlations. 相似文献

Ordinary and thermal diffusion of moisture in activated alumina are investigated using a new diffusion cell design and scheme of analysis reported earlier. The specific form of the mass flux equation has a pronounced effect on the magnitude of the associated thermal diffusion ratio. In the case of activated alumina-moist air, if a partial pressure gradient is used, then the thermal diffusion term is small if not zero.Free, Knudsen and surface diffusion all play a part in the diffusion through activated alumina. However, surface diffusion makes the major contribution and for this reason the model in this case can be simplified to a two parameter surface model.The activation energy for surface diffusion is constant and is approximately equal to the mean isosteric heat of absorption. In addition, mean pore radius, turtuosity, and other physical constants are computed from the least square fit of experimental data. Furthermore, the model is theoretically consistent over the entire concentration range (0≦ CA ≦ CAsat).A new fact about activated alumina (Grade F1) it that it does not transfer moisture in a nonisothermal condition so long as the partial pressures of moisture on the two sides of the pellet are the same. There appears to be no previous report of this fact in the periodical literature. 相似文献

The inclusion of children with special educational needs is a major challenge. Amongst the factors linked to a successful inclusive education policy, teachers’ attitude toward inclusion is particularly important. The present paper seeks to understand why general teachers exhibit less favourable attitude toward inclusion than special education teachers. We argue that general teachers’ low sense of efficacy can act as a mediator. To investigate this hypothesis, general and special education teachers were asked to report their attitude and efficacy. Results confirm that general teachers have less positive attitude toward inclusion than special education teachers. In addition, a mediational analysis confirmed that this discrepancy is partly sustained by general teachers’ lower sense of efficacy. Limits as well as future perspective are discussed. 相似文献

End effects on the flow of heat, mass or electrical energy through a cylindrical rod were investigated analytically. Three of the eight analytical solutions were evaluated on a computer and compared with the results of a numerical analysis package dubbed “Heating III” to show that both compared favorably.Platinum and Hastelloy X rods were subjected to an electrical current applied via two electrodes, one covering one end and the application of the other being thesubject of this investigation. End effects based on voltage deviations of one part in a thousand or more were found to extend for a length to diameter ratio ranging from 0·6 to 1·9 depending upon whether the small electrode position being investigated was at the center of the end or on the periphery of the end. Calculated results from Heating III showed excellent agreement with the experimental results.In addition to their reported applications, the analytical solutions represent a contribution to a neglected area of applied mathematical physics and as such should prove equally useful in other areas that are dynamically analogous. Also the discontinuous infinite integral technique of solution has proven to be a very powerful one. 相似文献

The PEACE Pack: an evaluation of interventions to reduce bullying in four Australian primary schools

Background The evidence is now quite clear that bullying in schools is an international problem. Bullying is widely regarded as a particularly destructive form of aggression, with harmful physical, social and emotional outcomes for all involved (bullies, victims and bystanders), and with particular risks for children with special needs. The research of the past 25 years confirms its widespread nature where it is most likely in groups from which the potential victim cannot escape—e.g. schools. In 1994 an Australian Commonwealth Government inquiry, following on from the pioneering work of research documented by Smith and co-workers, heralded a growing awareness of the need to address the issue of school violence, particularly bullying. Internationally, researchers have identified the impact of intervention programmes to reduce school bullying. In Australia a nationally and internationally used, systemically based intervention programme called the PEACE Pack, has previously been shown to be effective in reducing bullying in primary schools. Purpose The purpose of the present study was to provide further supporting longitudinal evidence regarding the efficacy of the PEACE Pack in markedly reducing bullying among young children of junior primary and primary school age. Further, the study also identified the characteristics of a small group of children who do not appear to benefit from intervention efforts. Finally, in this paper, a computer-based innovation for collecting school-based data regarding student perceptions of bullying is described. Sample The sample of 954 pupils comprised 458 males and 496 females from four Australian primary schools in Adelaide, a large metropolitan city in Australia. The pupils ranged in age from 5.4 to 13.5 years. Design and methods The study involved a pre- and post-test design and the administration of a questionnaire to evaluate the effectiveness of the implementation of the PEACE Pack programme to address the issue of school bullying. Results The interventions were effective in reducing the level of school bullying in the junior primary and primary schools, although there were variations in the gains achieved across the age range and across the four schools. Conclusions In the present study the systemic PEACE Pack interventions resulted in approximately one-fifth of pupils in the overall sample reporting that they were being bullied ‘less’ as a result of year-long interventions. This effect was greatest in the primary schools, particularly for boys. Consideration was given to a small group of students who reported being bullied ‘more’ after the interventions, and to the development of a computer-based assessment procedure for assessing the extent of bullying in schools. 相似文献

We provide new proofs to modified equivalent conditions for stability independent of delay of retarded and neutral delay differential systems. We also present a new test procedure for stability independent of delay. If the system is not stable independent of delay, the test is further applicable to obtain the intervals of delay for which the system is asymptotically stable. The usefulness and simplicity of the new test procedure is illustrated by numerical examples. 相似文献

An elaborate experimental set up is described that was used to measure the thermal expiration curves of heat recuperators, that had been constructed with guard heaters and vacuum insulation to minimize heat losses. A much more general model is used along with a precision numerical analysis technique to show that a film coefficient correlation of the Dittus-Boelter type did an excellent job of representing the results from 162 runs in which three feed gas temperatures, two flow rates, two particle size ranges, one bed diameter and five desciccants were used. For comparison sake the reported film coefficient correlation is finally assembled in a table along with others found in the literature. 相似文献
