This study assessed the feasibility of doing hearing screening in Migrant, American Indian and Early Head Start programs using otoacoustic emissions (OAE) technology. Staff members were trained to screen 0–3-year-old children for hearing loss using hand-held OAE equipment and a multi-step screening and referral protocol. Of the 3486 children screened as a part of the study, 77% passed an OAE screening at the first step, 18% more passed an OAE screening at the second step, and 5% were ultimately referred for medical or audiological follow-up. Eighty children were identified as having a hearing loss or disorder of the outer, middle or inner ear requiring treatment. Of these 80, six had permanent bilateral or unilateral hearing loss. Although the protocol suggested that the multi-step screening procedure should be completed within a 4-week time period or less, analysis of the data showed that for children requiring more than an initial OAE screening, the length of time over which the screening was completed ranged from 7 to 12 weeks. The median time required to complete a single OAE screening session was 4 minutes per child. The results demonstrate that OAE screening of young children using this protocol is practical and effective. The implications for conducting periodic hearing screening throughout early childhood are discussed. 相似文献

We investigated differences between field-study classrooms and traditional science classrooms in terms of the learning environment and students’ attitudes to science, as well as the differential effectiveness of field-study classrooms for students differing in sex and English proficiency. A modified version of selected scales from the What Is Happening In this Class? questionnaire was used to assess the learning environment, whereas students’ attitudes were assessed with a shortened version of a scale from the Test of Science Related Attitudes. A sample of 765 grade 5 students from 17 schools responded to the learning environment and attitude scales in terms of both their traditional science classrooms and classrooms at a field-study centre in Florida. Large effect sizes supported the effectiveness of the field-studies classroom in terms of both the learning environment and student attitudes. Relative to the home school science class, the field-study class was considerably more effective for students with limited English proficiency than for native English speakers. 相似文献

This essay considers the question of why we should teach science to K-2. After initial consideration of two traditional reasons for studying science, six assertions supporting the idea that even small children should be exposed to science are given. These are, in order: (1) Children naturally enjoy observing and thinking about nature. (2) Exposing students to science develops positive attitudes towards science. (3) Early exposure to scientific phenomena leads to better understanding of the scientific concepts studied later in a formal way. (4) The use of scientifically informed language at an early age influences the eventual development of scientific concepts. (5) Children can understand scientific concepts and reason scientifically. (6) Science is an efficient means for developing scientific thinking. Concrete illustrations of some of the ideas discussed in this essay, particularly, how language and prior knowledge may influence the development of scientific concepts, are then provided. The essay concludes by emphasizing that there is a window of opportunity that educators should exploit by presenting science as part of the curriculum in both kindergarten and the first years of primary school. 相似文献

This article describes a set of computerized tools that support the design and evaluation of competency-based training programs. The training of complex skills such as air traffic control and process control requires a competency-based approach that focuses on the integration and coordination of constituent skills and transfer of learning. At the heart of the training are authentic whole-task practice situations. The instructional design tools are based on van Merriënboer's 4C/ID* methodology (1997). The article describes a training design tool (Core) that supports the analysis and design for competency-based training programs and an evaluation tool (Eval) that supports the subsequent revision of this training design. 相似文献

Most counselors recognize the importance ofcultural competence in their work. As part ofeffective treatment, skills in accuratelydiagnosing clients from diverse backgrounds areessential, yet specific techniques addressingcultural differences to aid in the diagnosisprocess are underrepresented in the counselingliterature. The purpose of this article is tooffer one step toward the development ofdiagnostic methods suitable for an increasinglydiverse client base. The importance ofcultural competency during the diagnostic phaseof counseling is discussed, the nature ofculture and its influence on diagnosis isreviewed, and a practical conceptual frameworkthat can assist counselors in makingsystematic, culturally sensitive diagnosis ispresented. 相似文献

In New South Wales, Australia, the Department of Youth and Community Services is empowered by statute to deal with cases of child abuse and neglect. Its child protection services include the Montrose Child Life Protection Unit which is designed to support and complement the work of both the Intake Service, Field Service and most importantly the work of child protective facilities in the community. The service has intake crisis counselling and call out resources; maintains a central register; provides a facility for crisis residential care for children and families, diagnostic assessment, and a day programme. The emphasis in service delivery in New South Wales in the area of child protection is on multidisciplinary intervention. The Department of Youth and Community Services is involved in promoting interagency cooperation and co-ordination. Over and above a philosophy that underlies service delivery is the Montrose Unit's involvement in sensitising the community to the difficult and often demanding role of parenting. Montrose represents an attempt to create an environment where parenting myths can be examined from a reality base and strategies implemented for reeducation. 相似文献

Mothers' perspectives of children's peer-related social development were obtained from matched groups of young children with developmental delays, communicative disorders, and typically developing children. Structured interviews elicited information on numerous issues including mothers' views of the importance of children's social skills development, rationales with respect to why children succeed or had difficulties on specific social tasks, and the socialization strategies mothers employ to promote children's peer-related social development. Mothers also reported on their efforts to arrange play with peers for their child and the degree to which they monitored that play. Results indicated that mothers rated children's social development as highly important, offered primarily internal rationales (e.g., traits, dispositions) for success or difficulties in achieving social tasks, and endorsed moderate and low power socialization strategies. Differences across the three groups were minimal. Mothers arranged play with peers least often for children with developmental delays and communication disorders, but monitored play more extensively for children with delays. These finding were discussed in terms of mothers adopting a developmental orientation to understand children's social development and their implications for maternal participation in peer competence intervention programs. 相似文献
