Psychometric approaches to the identification of LD: IQ and achievement scores are not sufficient     

Francis DJ  Fletcher JM  Stuebing KK  Lyon GR  Shaywitz BA  Shaywitz SE 《Journal of learning disabilities》2005,38(2):98-108

Simulated data were used to demonstrate that groups formed by imposing cut-points based on either discrepancy or low-achievement definitions of learning disabilities (LD) are unstable over time. Similar problems were demonstrated in longitudinal data from the Connecticut Longitudinal Study, where 39% of the children designated as having LD in Grade 3 changed group placement with repeated testing in Grade 5. These results show that the practice of subdividing a normal distribution with arbitrary cut-points leads to instability in group membership. Approaches to the identification of children as having LD based solely on individual test scores not linked to specific behavioral criteria lead to invalid decisions about individual children. Low-achievement definitions are not a viable alternative to IQ-discrepancy definitions in the absence of other criteria, such as the traditional exclusions and response to quality intervention. If we accept the premise of multiple classes of low achievers, then we must develop identification systems that are valid and abandon systems whose only merits are their historical precedence and convenience.  相似文献   

Parental involvement in literacy development: using media texts     

Jackie Marsh  Philippa Thompson 《Journal of Research in Reading》2001,24(3):266-278

This paper reports on a small‐scale project which aimed to build upon the existing home literacy practices of a group of three‐ and four‐year‐old children living in the UK. The purpose of the project was to develop literacy materials and resources which could be borrowed from nursery and used within the home to promote children’s literacy development. Children’s informal literacy practices at home were identified using literacy diaries, which 18 families completed over a four‐week period. These documented children’s reading of both printed and televisual texts. In addition, interviews were conducted with 15 parents and carers. The paper reports on the findings from this stage of the project, which indicate that much of children’s reading was focused on popular cultural and media texts. Media boxes were developed as a literacy resource for use by parents and children in the home. The use of these media boxes by three families was documented and the initial findings, which suggest that the use of such resources draws on families’ cultural capital, discussed.  相似文献

Project PATRON—Audio and video on demand at the University of Surrey     

Jon Maslin  Elizabeth Lyon 《The Journal of Academic Librarianship》1998,24(6):464-468

In the March 1997 issue, Derek Law described the “Follet Program” which has provided finding and guided the development of digital library initiatives in the United Kingdom for several years now. In this column Elizabeth Lyon and Jon Maslin describe work at the University of Surrey which is a practical illustration of the success of the program in fostering leading edge experimentation resulting in production systems using a mix of off-the-shelf technology and local development. Project PATRON is an excellent example of the ways that libraries may support the teaching-learning process using technology enabled multi-media—CBL, University of Maryland, College Park, Maryland.  相似文献

Blended university teaching using virtual learning environments: conceptions and approaches     

Petros Lameras  Philippa Levy  Iraklis Paraskakis  Sheila Webber 《Instructional Science》2012,40(1):141-157

This paper reports findings from a phenomenographic investigation into blended university teaching using virtual learning environments (VLEs). Interviews with 25 Computer Science teachers in Greek universities illuminated a spectrum of teachers’ conceptions and approaches from ‘teacher-focused and content-oriented’, through ‘student-focused and content-oriented’, to ‘student-focused and process-oriented’. Using VLEs was described as a means of supporting: A—information transfer; B—application and clarification of concepts; C—exchange and development of ideas, and resource exploration and sharing; D—collaborative knowledge-creation, and development of process awareness and skills. The study suggests that pedagogical beliefs and circumstances underpinning face-to-face teaching are more influential in shaping approaches to blended VLE use than VLE system features. The authors propose that the findings could be used to inform educational enhancement initiatives and that there is a need for further discipline-focused research on blended teaching.  相似文献   

The Use of Research Electronic Data Capture (REDCap) Software to Create a Database of Librarian-Mediated Literature Searches     

Jennifer A. Lyon  Rolando Garcia-Milian  Hannah F. Norton  Michele R. Tennant 《Medical reference services quarterly》2013,32(3):241-252

Expert-mediated literature searching, a keystone service in biomedical librarianship, would benefit significantly from regular methodical review. This article describes the novel use of Research Electronic Data Capture (REDCap) software to create a database of literature searches conducted at a large academic health sciences library. An archive of paper search requests was entered into REDCap, and librarians now prospectively enter records for current searches. Having search data readily available allows librarians to reuse search strategies and track their workload. In aggregate, this data can help guide practice and determine priorities by identifying users’ needs, tracking librarian effort, and focusing librarians’ continuing education.  相似文献
