This paper describes the roles of teachers and school psychologists and presents an overview of current and prospective methods of providing services to special needs children. On the basis of the literature and professional experience, it is suggested that changes are needed in the provision of special education services. The consultative relationship between teachers and school psychologists is viewed as the key to successful classroom intervention for special needs children. Although each profession brings expertise into the consultative relationship, better training is needed for teachers and school psychologists to ensure that effective intervention strategies are developed.  相似文献

Instructional design, as it is traditionally conceptualized, is being challenged on several fronts, through surveys of design practice, cross-disciplinary studies of design practice, and practical criticism focusing on issues of design models' flexibility and efficiency. Collectively these challenges raise questions about the viability of the instructional design enterprise. This paper reviews these challenges and attempts to respond by offering alternative approaches to instructional design.  相似文献

The objective of this study was to examine current teacher and mental health professional ratings regarding the relative seriousness of 50 specific children's behavior problems and to compare the results to those found by Wickman (1928). Wickman's questionnaire and procedures were replicated to insure comparability. A second objective was to extend Wickman's work so that children's ratings of their own behavior problems may be ascertained. An increase in the similarity between teachers' and mental health professionals' judgements concerning the seriousness of specific children's behavior problems was found. These findings were attributable to a more pragmatic approach taken by mental health professionals. A very high agreement on the seriousness of specific behavior problem ratings was demonstrated by children and teachers. This similarity may be the result of proximity of effects.  相似文献

In a series of three papers, we attempt to evaluate the past scientific performance of the three main particle accelerators at the Geneva-based European Organization for Nuclear Research (CERN) over the period since 1960, and to assess the future prospects for CERN and its users during the next ten to fifteen years.We concerned ourselves in a previous paper (Paper 1 - Martin and Irvine [51] with the position of the CERN accelerators in world high-energy physics relative to those at other large laboratories working in the field. We dealt primarily with the period from 1969 to 1978, and attempted to establish how the experimental output from the three principal CERN accelerators, taken as a whole, compared with that from other major facilities. In undertaking this comparative evaluation, we drew on the method of “converging partial indicators” used in previous studies of three Big Science specialties.In contrast, this paper (Paper II) focuses in detail on the scientific performance of each of the CERN accelerators taken individually. In particular, it asks, first, how the outputs from the CERN 28 GeV (giga or billion electron-volts) Proton Synchrotron compare with those from a very similar 33 GeV American accelerator at Brookhaven National Laboratory over the past two decades? Second, how great have been the experimental achievements of the Intersecting Storage Rings in world terms? And, third, how do the outputs from the CERN 400 GeV Super Proton Synchrotron and from a rival American machine at Fermi National Accelerator Laboratory compare? Attempts are then made to identify the main factors responsible for determining the relative scientific performance of each CERN machine.These factors are of relevance to the subject of a third paper (Paper III - Martin and Irvine [52]) which sets out to assess the future prospects for CERN and in particular for LEP, the large electron-positron collider scheduled for completion in the latter part of the 1980s. What are the construction requirements (financial and technical) associated with LEP, and how easily will they be met? How does the scientific potential of LEP compare with that of other major accelerators under construction around the world? And, in the light of the previous record of the CERN accelerators, to what extent is this potential likely to be realized? The paper concludes with a discussion of the extent to which predictive techniques can be utilized in the formulation of scientific priorities, and of the problems in current science policy-making that such techniques might help address.  相似文献

Dual-language programs are becoming increasingly popular among educators and the public in general. In these programs, students aim at attaining full proficiency in English and another language while reaching an academic achievement at or above grade level. This article describes a series of pedagogical practices in the context of dual-language classrooms. We set the discussion across three defining characteristics of our constructivist perspective: learning as collaboration, teachers as facilitators, and language and culture as intertwined elements in schools. In sum, we postulate that dual-language programs bring equity to schools.  相似文献
