Although mainstream preschool programs have been in existence since the 1970s, little is known about the ways in which typical children attempt to understand what it means for a peer to have a disability. In this study, 4-year-old children without disabilities who were enrolled in a mainstream preschool class explained their peers' disabilities by referring to concepts of immaturity, accident, or adaptive equipment to account for the behavioral differences that they observed. The implications of these cognitions for children's developing attitudes and behaviors toward peers with disabilities are discussed. 相似文献

Research Findings: The present study used a longitudinal design to identify how sleep habits and learning-related behaviors impact the development of cognitive skills in preschoolers (ages 3–5). Sixty- seven children with parental report and cognitive skill assessment data were included. Scores on the Differential Ability Scales (C. Elliott, 1990) were obtained at ages 3, 4, and 5. A Sleep Questionnaire (D. Gozal, 1998) with 12 items from the Child Behavior Checklist (T. M. Achenbach &; L. A. Rescorla, 2000) related to children's attention and activity levels was administered at age 3. Growth curve changes in cognitive scores were estimated using hierarchical linear modeling. Parental reports of nighttime sleep duration predicted level of cognitive skills at 3 years. The effect of sleep duration on cognitive scores was constant across age. Practice or Policy: Sleep and learning-related behaviors distinguish the cognitive skills children bring to preschool programs and impact gains made in skills while in preschool. 相似文献

Research Findings: Using a qualitative research approach, this article explores teachers’ roles as scaffolders of infants’ play and the changing nature of their individualized support for infants’ learning and development through play in an infant group care setting. Three infant teachers in a child care center were followed over 3 months. Observations, interviews, ongoing conversations, e-mails, and reflective notes were used as data sources. Findings revealed that the teachers thought deeply about their roles as supporters of infants’ play, and they made intentional choices in scaffolding infants’ play. Each teacher's ways of empowering infants in play were grounded in her views of infants as learners and were individualized to accommodate children's unique learning styles and personalities. Practice or Policy: This study provides a window into the ways in which teachers working with the youngest children can set the stage for later learning. 相似文献

Research Findings: Research suggests that early care and education programs are most effective when they include strong components of family involvement. The Center for the Study of Social Policy recommended that early care and education programs build family-centered practices to strengthen families and reduce the incidence of child abuse and neglect. This article summarizes a statewide effort to implement this strategy, called Strengthening Families through Early Care and Education. We analyzed program self-assessments submitted by 186 early care and education programs. Analyses revealed that Head Start programs had better support systems in place for families than did “mainstream” (non–Head Start, non-accredited) early care and education programs. Results also showed that a small amount of state and local funding provided enough incentive for programs to improve their family-strengthening practices. Commitment and collaboration at the state level led to a sustainable impact by infusing “strengthening families” concepts into the early care and education field statewide. 相似文献

We designed support for volitional control with four stages for goal initiation (“Want it”), goal formation (“Plan for it”), action control (“Do it”), and emotion control (“Finish it”) based on theories and models of volition. We implemented the support in mathematics courses offered at a community college. We examined the effects of volitional control support on students’ motivation (i.e., intrinsic value, self-efficacy), emotions (enjoyment, pride, anger, anxiety, shame, hopelessness, and boredom), effort regulation, and achievement. We found significant effects of the volitional control support on intrinsic value, enjoyment, anger, anxiety, and boredom. Findings are discussed to improve the design and development of the volitional control support. Limitations and implications of the study are presented as well. 相似文献

This study examined the effects of professional development on teachers’ assessment literacy between two groups of teachers: (1) teachers who were involved in ongoing and sustained professional development in designing authentic classroom assessment and rubrics; and (2) teachers who were given only short-term, one-shot professional development workshops in authentic assessment. The participating teachers taught Year 4 and 5 English, science, and mathematics. The findings showed that the assessment literacy of teachers who were involved in ongoing, sustained professional development had increased significantly during the second year of study. These teachers had also gained a better understanding of authentic assessment. 相似文献

This study investigates the socialization and professional experiences of primary school physical education teachers (PSPETs) in the Asian context of Hong Kong. A qualitative research design is adopted. The researcher used semi-structured interviews, supplemented by documentary sources (diaries) for conducting data collection. Eleven PSPETs participated in this study. Data were analysed through open axial and selective coding. The concepts of organizational sensitivity, sources of satisfaction, dealing with influential persons or critical incidents, status of the profession, educational reform as a trend, and versatile roles are revealed in the theory of ‘Diversified Professionalism’. The substantive theory thus contributes to an increased appreciation of the PSPETs’ work and to the literature on physical education teachers’ professionalization and professionalism. 相似文献

In this paper, we consider the super-twisting observer-based sliding mode control algorithm with fuzzy variable gains (STOSMC) for the fully-actuated hexarotor. Our hexarotor has full actuation due to six titled propellers that allows to control position and orientation (attitude) simultaneously, and resolves the singularity problem of the rotational matrix by using the quaternion modeling framework. We show that the proposed STOSMC for the hexarotor guarantees finite-time convergence of the estimation error and asymptotic stability of the hexarotor. In simulations, we demonstrate the nonsingularity and fully-actuated control performance of the hexarotor by considering extreme position and attitude control scenarios. Moreover, the simulation results show that the hexarotor achieves the fast and precise tracking performance to the desired position and the desired attitude and the chattering phenomenon is reduced compared with the fixed-gains observer-based super-twisting sliding mode control due to the fuzzy mechanism. 相似文献

We study the role of the relationship among inventors and intermediaries in the licensing of university inventions. We suggest that a prior inventor-intermediaries relationship positively influences licensing rates through selective retention of higher quality relationships and mutual learning in the relationship, enabling intermediaries to reduce both information asymmetry and search costs between inventors and potential licensees. We argue that the influence of a prior inventor-intermediaries relationship on licensing is especially important before intellectual property protection is attained and can be substituted by the buyer-side contacts of inventors and intermediaries. We test these predictions using 919 inventions from the technology transfer office at Stanford University. This study has implications for the policies and design of university technology licensing organizations. 相似文献

AbstractIn recent years, volunteering has received strong research attention from both scholars and practitioners. For the most part, involvement in volunteer activities has been identified as an important determinant of future volunteering. Through revalidating an existing instrument, the purpose of this study was to assess the dimensions of volunteer satisfaction at the 2012 London Olympic Games and its impact on future volunteer behaviour. The findings of this study shed light on the identification of volunteer satisfaction factors in the mega sporting event setting, particularly for a unique type of volunteer (i.e. media worker) assigned to a special set of tasks. Unlike Galindo-Kuhn and Guzley’s results that revealed participation efficacy and group integration to be strong predictors of volunteer satisfaction, organizational support was the primary predictor for media centre volunteers’ re-participation intention towards future volunteering programmes. 相似文献
