Digital repositories require good metadata, created according to community-based principles that include provisions for interoperability. When metadata is of high quality, digital objects become sharable and metadata can be harvested and reused outside of the local system. A sample of U.S.-based repository administrators from the OpenDOAR initiative were surveyed to understand aspects of the quality and creation of their metadata, and how their metadata could improve. Most respondents (65%) thought their metadata was of average quality; none thought their metadata was high quality or poor quality. The discussion argues that increased strategic staffing will alleviate many perceived issues with metadata quality.  相似文献

The twenty-first century has seen unprecedented investment from governments around the world in educational technologies in schools. This paper investigates Australian teachers’ adoption and use of a popular technology that has been extensively supported by governments and school systems: the interactive whiteboard (IWB). The study suggests that a number of the barriers identified in the early days of adoption and use of this technology, such as professional support and access, still remain for many teachers, thereby impeding effective practices. The research also found that primary school teachers were using the technology in diverse ways, in contrast to secondary teachers who were using the IWB mainly for instructionist, presentational purposes. We conclude by considering various ways of reducing the effect of the identified barriers to support implementation of educational technologies in the classroom, especially the next generation of technologies promoted by governments and systems.  相似文献

A review of social interventions for students with learning disabilities   总被引:2,自引:0,他引:2  
Twenty-two studies are reviewed that report the effects of social skills training and intervention with 572 children identified as learning disabled between 5 and 19 years of age. These studies are reviewed to examine characteristics and components of intervention effectiveness. Age and sex of subjects, grade grouping, group size, intervention duration, intervention procedures, subject selection, and type of interventional model are examined to find patterns that reflect intervention success. Several intervention characteristics and components are associated with social intervention effectiveness: selecting subjects who had social skills difficulties or low peer acceptance, using cognitive-behavioral intervention procedures, providing individual or small group instruction, and applying long-term intervention and training. Discussion focuses on difficulties in comparing studies to determine intervention effectiveness through the examination of outcome measures, a call for revisions in future reporting of social interventions in the literature, and those intervention factors that relate to increases in peer acceptance.  相似文献

Understanding the relationship between executive functioning and its connection to working memory and adaptive functioning can inform planning and employment efforts. This study explored the relationship between memory and adaptive functioning with a sample of Autistic youths/young adults. Participant mean age was 21.3 (SD = 3.0). Of the 22 participants, 17 were male, and 19 white, non-Hispanic/Latina/o/x. All but one lived with their parent(s). Participants were administered a full battery assessing cognitive ability (WAIS-IV), memory and executive functioning (WMS-IV and DKEFS), autism symptomatology (ADOS-II), and adaptive functioning (SIB-R). A multivariate lasso regression model was used. Memory, especially as measured on the WMS-IV, was found to be significantly related to adaptive functioning and autism symptomatology. There appears to be continuing evidence that memory is highly related to adaptive functioning and autism symptomatology. Interventions involving auditory and immediate memory could be helpful in promoting more mutually effective social interactions necessary for positive employment outcomes.  相似文献

This study aims to evaluate the perceptions of librarians with regard to artificial intelligence in academic libraries. An online survey of 24 questions was distributed through library distribution lists in Canada and the United States at the end of the summer in 2019. Findings suggest that librarians do not agree on a definition of artificial intelligence which is in keeping with this emerging field. The survey responses highlight the fact that academic librarians require more training with regard to artificial intelligence and its potential applications in libraries. Other important implications include a recognition that library patrons are interested in AI and that little to no programming about it has been offered in academic libraries. Very few studies have focused on academic librarians' perceptions of AI. This article highlights some useful practical implications for AI technologies in libraries and how AI could help improve library services and workflows.  相似文献

Research Findings: The present study examined the degree to which the association between interactive peer play and academic skills was dependent upon the level of classroom quality for a representative sample of culturally and linguistically diverse urban Head Start children (N = 304 children across 53 classrooms). Peer play interactions within the classroom were assessed by teacher assistants in the fall of the year; observations of the quality of classroom instructional, emotional, and organizational support were conducted in the middle of the year; and norm-referenced direct assessments of literacy, language, and mathematics skills were administered in the spring. Findings from multilevel models indicated that disruptive and disconnected peer play behaviors early in the preschool year were associated with lower literacy and language skills regardless of classroom quality. However, interactive peer play early in the year was associated with higher mathematics outcomes when children were enrolled in classrooms characterized by high instructional support. Practice or Policy: Implications for early childhood research, practice, and policy are discussed.  相似文献
