A closer examination of the education for all handicapped children act: A guide for the 1980S

The United States Congress has mandated that state and educational agencies make available to all handicapped children a free appropriate education. The purpose of this legislation has been primarily to protect the rights of handicapped children and their parents. The present paper discusses identification and evaluation guidelines that have been promulgated under the Education for All Handicapped Children Act. Procedures for Individual Education Programs that are in accordance with federal legislation are delineated. To satisfy federal mandates concerning the placement of handicapped children, public school systems are required to utilize a least restrictive environment, whereby complete segregation of handicapped from nonhandicapped children is prohibited. In further accordance with this legislation, either the parent or public agency may initiate a hearing for the purpose of challenging the identification, evaluation, or educational placement of the child.     

A Curve for all reasons

The cause-effect relationship for a wide variety of biological processes from molecular to ecosystem levels can be described by a curvilinear function called the rectangular hyperbola. Although a simple algebraic equation adequately describes this curve, biological models have generated different equations incorporating biologically meaningful parameters. The Michelis-Menten equation describing enzyme kinetics, and the Type II functional response of predators to changing prey densities are two such examples.     

Educating all children: ten years later

This article reviews the Tenth Annual Report to Congress on the Implementation of The Education of the Handicapped Act (EHA), covering the 1986-1987 school year. In addition to reporting the current status of services (i.e., numbers of students served, their placement, resources allocated and needed for their support), the report also discusses and cites data pertinent to (a) transition from secondary education; (b) state and federal efforts anticipating full implementation of preschool special education services under Public Law 99-457; and (c) the classification of students with learning disabilities. Some directions for research on special education at a national level are suggested.     

A future of reversals: Dyslexic talents in a world of computer visualization

With the recent revival of visual approaches at the forefront of several scientific, mathematical, and technological developments, this paper proposes that visually oriented dyslexics may be in an increasingly favorable position in future years. The same set of traits which has caused them so much difficulty in traditional verbally-oriented educational systems, may confer special advantages in emerging new fields which rely heavily on visual methods of analysis—fields which employ powerful graphic workstations and supercomputers to visualize complex scientific data. Recent trends have also led some technical professionals to become aware that their own special talents seem to be closely associated with certain dyslexic traits. It is argued that similarly mixed talents have been major factors in the accomplishments of a number of important historical figures.     

Dyslexic children show deficits in implicit sequence learning,but not in explicit sequence learning or contextual cueing

Dyslexia is a specific learning disability characterized by difficulties with accurate and/or fluent word recognition and by poor spelling abilities. The absence of other high level cognitive deficits in the dyslexic population has led some authors to propose that non-strategical processes like implicit learning could be impaired in this population. Most studies have addressed this issue by using sequence learning tasks, but so far the results have not been conclusive. We test this hypothesis by comparing the performance of dyslexic children and good readers in both implicit and explicit versions of the sequence learning task, as well as in another implicit learning task not involving sequential information. The results showed that dyslexic children failed to learn the sequence when they were not informed about its presence (implicit condition). In contrast, they learned without significant differences in relation to the good readers group when they were encouraged to discover the sequence and to use it in order to improve their performance (explicit condition). Moreover, we observed that this implicit learning deficit was not extended to other forms of non-sequential, implicit learning such as contextual cueing. In this case, both groups showed similar implicit learning about the information provided by the visual context. These results help to clarify previous contradictory data, and they are discussed in relation to how the implicit sequence learning deficit could contribute to the understanding of dyslexia.

Cam McRobbie: A man for all occasions

This article reviews the contributions of Campbell John McRobbie, Cam, to science education scholarship and research within the Australasian Science Education Research Association (ASERA) and within the broader science education community. Cam provided strong leadership and vision across many spheres of science education and leaves a legacy to the field that includes, (a) long term administrative and academic support of ASERA as an organization and for its incorporation, (b) firm establishment of RISE as an international journal of high quality, and (c) strong collegial approach to supporting the research of his colleagues including early career researchers and research degree candidates.

Social acknowledegments for children with disabilities: effects of service dogs

While service dogs are known to perform important tasks for people using wheelchairs, such as retrieving dropped items or pulling a wheelchair, they may also serve as an antidote for social ostracism. Adults in wheelchairs have been found to receive many more social acknowledgements when a service dog is present than when not. This study examined whether disabled children in wheelchairs with service dogs receive more frequent social acknowledgment than when no dog is present. Behaviors of passersby in response to children in wheelchairs were recorded in shopping malls and on school playgrounds. In both settings, social acknowledegments (e.g., friendly glances, smiles, and conversations) were substantially more frequent when a service dog was present. Social effects of the dog were more pronounced in shopping malls, typical of unfamiliar settings where the child would be likely to experience being ignored or overlooked. Service dogs may assist in normalizing the social interactions for children with disabilities producing social isolation.
