As institutions of Higher Education try to balance limited resources with the rising costs of technology, some institutions are turning to Open Source software for campus-wide applications such as course management systems and portals. The assumption is that Open Source will provide the flexibility to build pedagogically sound learning environments while increasing technology efficiencies. This paper outlines the current state of Open Source software deployment in US Higher Education based on a survey of 772 Chief Academic Officers and Chief Information Officers conducted in 2006. The results indicate that Carnegie classification is a critical differentiator of awareness, adoption, and perceptions of Open Source software applications, with perceived cost of ownership being the key driver of Open Source adoption. Moreover, the study shows that institutions have made little progress in the development of polices and procedures for Open Source regulatory compliance and security. The study serves as a baseline for future research into the conditions for successful use of Open Source for supporting integrated learning environments that deliver campus-wide efficiencies.

Phonological awareness, phonological memory, and phonological access to lexical storage play important roles in acquiring literacy. We examined the convergent, discriminant, and predictive validity of these phonological processing abilities (PPA) in 389 3-, 4-, and 5-year-old children. Confirmatory factor analysis supported the validity of each PPA as separate from general cognitive ability and separate from each other. Multigroup structural equation modeling (SEM) with mean structure demonstrated that older preschoolers have better developed latent PPA than younger preschoolers but that the structure of PPA is equivalent. RAN was found uniquely associated with letter knowledge and text discrimination in younger preschoolers, and PA was found uniquely associated with word reading skills in older preschoolers. Finally, general cognitive ability was only indirectly associated with emergent literacy via PPA. These results highlight the importance of PPA in the early literacy development of English-speaking preschool children.  相似文献

The development of support staff was a key aspect of the Labour government’s reform of the school workforce in England. As part of this strategy approximately 25,000 Teaching Assistants (TAs) gained Higher Level Teaching Assistant (HLTA) status and were deployed in schools in a variety of roles, often operating in a quasi-teaching role. The research re-visits individuals who had acquired HLTA status between 2006 and 2009 and had participated in a questionnaire survey regarding their role at that time. A duplicate questionnaire was distributed in 2013 to 305 of these HLTAs and was followed up in 2014 by focus groups with self-selecting individuals from the original sample. To date there has been little research relating to the development of the HLTA role and the implications this has for both teachers and pupils, particularly in terms of provision for the most vulnerable learners.  相似文献

This article considers in a wide perspective the crisis in the assessment of examinations in A‐level English Literature and current attempts to address the problems. Examining the implications of a survey of recent reports initiated by the regulator, it argues that trying to ensure reliability merely through technological advances and changes in examining practice obscures the need for English teachers’ communal understanding of academic standards to be developed through their professional experience. It proposes ways in which this should be achieved, for example by developing current and potential professional networks and communities of practice.  相似文献

A Hunter College librarian, with public library experience, offered a series of drop-in workshops Saturday afternoons open to all students and questions regarding Web or Windows use in the academic year, 2000-2001. The intention of the workshops was to address the continuous needs of students lacking technological and informational literacy. The success of these workshops led to this investigation of the implications of 21st century technology on non-traditional students from the perspective of bibliographic instruction as well as reference desk service. The perspective is that of the urban educational environment of City University of New York and Hunter College. The histories of open admissions at CUNY and the current efforts to abolish remediation are examined.  相似文献

This article maps the biomedical literature of Nigeria by source/origin of publications and authorships from 1967 to 2002. This mapping is expected to provide crucial information to both government and others taking funding and related decisions regarding biomedical research in Nigeria. Data was collected from MEDLINE. Scientists publishing on Nigerian biomedicine have written 6,820 articles in 295 journals/sources. Only eight of the 121 local journals that published biomedical research in Nigeria during the period were included in MEDLINE's listing (2.72%), while there were 32 (10.84%) regional and 255 (86.44%) external journals used. Local journals appeared to be more heavily used than regional and external ones. It was also shown that MEDLINE does not adequately represent Nigeria's biomedical literature.  相似文献
