Children with autism have complex learning and behavioural challenges which typically require comprehensive educational and therapeutic services. In recent years there have been many developments in the philosophy, methodology, and scope of intervention for this population. Factors such as early intervention, criterion‐referenced assessment, the combination of applied behaviour analysis and developmentally appropriate practices (DAP), parent training, and public school inclusive education have been noteworthy. This article describes a comprehensive continuum of services model for children with autism developed by a human services agency in Massachusetts which incorporates these and additional empirically‐based approaches. Service components, methodologies, and program objectives are described including representative summary data. The article concludes with a discussion of educational, therapeutic, and research issues which address “best practice” approaches toward children with autism.  相似文献   

Interactive Evaluation of the Ostensive Model Using a New Test Collection of Images with Multiple Relevance Assessments     

Iain Campbell 《Information Retrieval》2000,2(1):89-114

The Ostensive Model proposes a manner of structuring the uncertainty associated with individual relevance judgements as sources of evidence in relevance feedback. It proposes temporal profiles of uncertainty, motivating the application of a particular class of discount function with respect to the age of the evidence. This paper presents an initial evaluation of the relative effectiveness of different uncertainty discount functions.A novel direct manipulation interface to a multimedia retrieval system embodying the Ostensive Model is outlined briefly. The paper describes the construction and characteristics of a new image test collection utilising multiple binary relevance assessments. The use of such multiple assessments and multiple interpretations of them are discussed. The evaluation environment is detailed in terms of the interface, test collection, and tasks set to users. Multiple interpretations of the results, and the statistical significance of comparisons are presented.The results obtained in the evaluation are consistent with the proposals of the Ostensive Model—reinforcing a particular evidence profile. The results give clear pointers to further, more specific, evaluations.  相似文献   

Four Blocks for Literacy     

Robin Campbell 《Literacy》1999,33(1):29-32

The literacy hour within the National Literacy Strategy is now part of primary classroom practice in the UK. That literacy hour consists of four distinct parts which are debated here. In addition an alternative Four Blocks framework, as used by some schools in the USA, is explored. The differences between those approaches are noted which raise questions about the time allocation, a sustained involvement with reading and writing, and teacher autonomy in the literacy hour.  相似文献   

The communication of laboratory investigations by university entrants     

Bob Campbell  Loveness Kaunda  Saalih Allie  Andy Buffler  Fred Lubben 《科学教学研究杂志》2000,37(8):839-853

The purpose of the study reported here was to analyse the ways in which unversity entrant science students carry out and communicate experimental activities and to identify a model to explain characteristic communication practices. The study was prompted by a need to inform the development of an introductory laboratory course. The students studied shared an educational background characterised by a lack of experience with laboratory work and scientific writing. Seven groups of three students were studied. The investigative strategies of these groups were observed. Laboratory reports were used to identify the ways in which students communicated these strategies. Data are presented that show a discrepancy between the strategies used and those reported. The results suggest that: (i) students' perceptions of the purpose of a laboratory task influence their decisions on what to report; (ii) understandings of laboratory procedures greatly influence their decision on what to report and on how much detail to include in a report and; (iii) knowledge of discourse rules contributes to effective reporting. It is concluded that students' communication of an investigation results from the differential operation of various perceptual filters that determine both the procedural and discourse elements of their reports. It is recommended that the communication of science should be taught explicitly and alongside the procedures and concepts of science. © 2000 John Wiley & Sons, Inc.

Reading Myanmar's inland fisheries: postcolonial literature as theoretical lens     

Stephen Campbell 《Inter-Asia Cultural Studies》2019,20(1):2-18

Interdisciplinary in scope, this article takes up the 1950 short story, “Ko Danga,” by Burmese author Kyay Ni, as a critical lens through which to approach the contemporary political economy of Myanmar's inland fisheries. Due to its level of ethnographic detail, Kyay Ni's account of the inland fisheries regime in early postcolonial Burma provides an effective historic baseline against which to assess more recent developments in this sector – developments outlined herein based on interviews and research trips to inland fishery locations in Myanmar's Ayeyarwady Region. Going further, the article argues that Kyay Ni's writing offers heterodox insights into contemporary political economic concerns, of relevance in Myanmar and more broadly.  相似文献   

Thermodynamic properties of reactive gas mixtures     

Ashley S. Campbell 《Journal of The Franklin Institute》1951,251(4):437-452

The foregoing study shows that the comparative behavior of fixed composition and chemical equilibrium, when compelled to undergo isentropic changes of state from the same initial point, depends first on the type of chemical reaction present. Chemical reactions are shown to fall into three classes, depending upon the algebraic sign of the product of the mole change and heat of reaction. The order of magnitude of the difference between the two systems depends on the magnitudes of temperature, heat of reaction, heat capacities and a fourth quantity best described as the mobility of the system.To include more general problems in which inert gases may be present, or more than a single reaction takes place, the analysis must be extended considerably.  相似文献
