This study examined the underlying structure of the Nonverbal Literacy Assessment (NVLA), an instrument designed to measure emergent literacy for K–fourth‐grade students with severe developmental disabilities. The NVLA was conceptualized as having six constructs that reflected emergent literacy skills: (a) phonemic awareness, (b) phonics, (c) comprehension, (d) vocabulary, (e) listening comprehension, and (f) text awareness. Confirmatory factor analysis using data from 207 student administrations was used to examine the six‐factor model and two alternative models. Results suggested that all three models fit the data, but the high corrections coefficients among the constructs suggested that a one‐factor model of emergent literacy was the best‐fitting model. Implications and limitations are discussed. © 2010 Wiley Periodicals, Inc.  相似文献

Twin births are increasing at a rapid rate, yet many educational personnel throughout the world are unaware of the needs of twins in school. Stereotypical views of twins as pathologically close or excessively dependent pervade educational policies and practices, despite the fact that twins do not differ from singletons on rates of psychological disturbance. Research shows that many schools implement strict policies for classroom placement of twins, yet the effects of such policies on twins' development and educational attainment are currently unknown. Recommendations for school personnel and future directions for this formative area are discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 429–438, 2003.  相似文献

Values such as respect for autonomy, safety, enablement, independence, privacy and social connectedness should be reflected in the design of social robots. The same values should affect the process by which robots are introduced into the homes of older people to support independent living. These values may, however, be in tension. We explored what potential users thought about these values, and how the tensions between them could be resolved. With the help of partners in the ACCOMPANY project, 21 focus groups (123 participants) were convened in France, the Netherlands and the UK. These groups consisted of: (i) older people, (ii) informal carers and (iii) formal carers of older people. The participants were asked to discuss scenarios in which there is a conflict between older people and others over how a robot should be used, these conflicts reflecting tensions between values. Participants favoured compromise, persuasion and negotiation as a means of reaching agreement. Roles and related role-norms for the robot were thought relevant to resolving tensions, as were hypothetical agreements between users and robot-providers before the robot is introduced into the home. Participants’ understanding of each of the values—autonomy, safety, enablement, independence, privacy and social connectedness—is reported. Participants tended to agree that autonomy often has priority over the other values, with the exception in certain cases of safety. The second part of the paper discusses how the values could be incorporated into the design of social robots and operationalised in line with the views expressed by the participants.  相似文献

This study examined the links among adolescents' representations of their relationships with parents, friends, and romantic partners. Sixty-eight adolescents were interviewed three times to assess their working models for each of these types of relationships. Working models of friendships were related to working models of relationships with parents and romantic partners. Working models of relationships with parents and romantic partners were inconsistently related. A similar pattern of results was obtained for self-report measures of relational styles for the three types of relationships. Perceived experiences were also related. Specifically, support in relationships with parents tended to be related to support in romantic relationships and friendships, but the latter two were unrelated. On the other hand, self and other controlling behaviors in friendships were related to corresponding behaviors in romantic relationships. Negative interactions in the three types of relationships also tended to be related. Taken together, the findings indicate that the representations of the three types of relationships are distinct, yet related. Discussion focuses on the nature of the links among the three.  相似文献

Research Findings: Shared book reading provides a meaningful context for rich conversations to occur between a child and an adult and offers opportunities for children to be exposed to a range of vocabulary and concepts that often extend beyond their everyday experiences. Few studies have examined parent–child shared book reading as a context for embedding mathematical discussion. The purpose of this study was to examine systematically the effect of training parents to focus on mathematical concepts and vocabulary during shared book reading. Specific research questions were as follows: (a) Did parents increase their use of math talk during shared storybook reading following training? (b) Did parents generalize intervention strategies? And (c) did children increase their use of math talk during shared storybook reading? Results from a yoked multiple-baseline design with 6 dyads indicated variability across the dyads with 2 general patterns. Math talk increased following training for 3 of the dyads, whereas verbal mathematical behavior did not show consistent change for the other 3 dyads. Practice or Policy: Results are discussed in the context of home support for early mathematical development.  相似文献

Twenty-one dual-earner families whose preschool-aged children entered day care before 6 months of age and 19 dual-earner families whose preschool-aged children entered day care during the second year of life filled out questionnaires on the nature of their children's caregiving environment; their perceptions of the effects of day care on parent-child interaction and children's development; their overall job satisfaction; social support networks; and personal well-being, marital stress, and companionship. Mothers and fathers reported high levels of satisfaction with the caregiving environment and the effects of day care. Parental perceptions of the effects of day care on parent-child interaction and children's development did not differ as a function of time of entry into day care. Parental perceptions of selected parent-child variables were associated with job satisfaction, social support, and the marital measures. Parental perceptions of parent-child interaction were related to their perceptions of the effects of day care on children's social and cognitive skills. Mothers and fathers differed in these perceptions. There was some support for a conceptual link between marital variables and children's functioning in day care.  相似文献

Security measures have been well established within the waterfall development life cycle model. However, more software projects are using the spiral development life cycle model. Software developers and project managers can easily forget about adapting security measures. The spiral model uses iterative steps that can create changes in each phase of software development process. This will challenge security to ensure the application has few flaws or vulnerabilities that could be exploited. Failure to impose the right security measures at each of these phases can open up vulnerabilities for hackers to exploit and prove costly in patching. This paper will explore areas where security can be engaged within each iteration step of the spiral development model. This way security can continue protection of the software product as it becomes ready for deployment. The paper will help organizations realize where to deploy security measures to reduce vulnerabilities in the software application.  相似文献

Didactic and laboratory anatomical education have seen significant reductions in the medical school curriculum due, in part, to the current shift from basic science to more clinically based teaching in North American medical schools. In order to increase medical student exposure to anatomy, with clinical applicability, a student-run initiative called surgically oriented anatomy prosectors (SOAP) club was created within the extracurricular program at the Schulich School of Medicine and Dentistry, The University of Western Ontario, London, Canada. SOAP invites surgeons and residents from various surgical specialties to demonstrate, on a cadaver, a surgical procedure of their choosing. During the demonstration, the anatomy, as it relates to the surgical procedure, is discussed. The students then break into smaller groups to examine the relevant anatomy on the cadavers, during which time the discussion is broadened. The group continues the conversation in a social environment with refreshments. SOAP is one of the most popular extracurricular clubs with 65% of first and second year medical students registered as members. The high demand for SOAP, along with the positive participant feedback, may be due to its utilization of the principle of education through recreation, which seeks to provide opportunities for learning seamlessly throughout all facets of life. It also demonstrates the desire, amongst certain medical students, to learn applied anatomy, particularly within a surgical context.  相似文献
