The goals of this study were to explore the deficits in working memory associated with literacy disorders (i.e. developmental disorders of reading and/or spelling) and the developmental trajectories of these working memory deficits. The performance of 28 children with literacy disorders was compared to a non-disabled control group with the same group size at five bi-annual times of measurement in a three-year-longitudinal study beginning at the end of primary school (9.5 years of age). Storage capacity and central-executive working memory were assessed in phonological and visual-spatial modalities, the latter under static and dynamic conditions. Overall, children with literacy disorders were outperformed by their typical developing peers in all phonological and in dynamic visual-spatial storage and central-executive tasks except for the static visual-spatial storage task. Results at single times of measurement revealed that the most consistent deficit was found in the storage capacity of the phonological loop. An additional central-executive impairment is supported by low backward spans. The causes for output deficits in dynamic visual-spatial tasks and good performance under static visual-spatial condition are discussed. 相似文献

ABSTRACT Taking advantage of professional development opportunities is imperative for new academic librarians. Even if not a position requirement, continuing education and professional involvement have the potential to inspire and improve job performance. While online resources should not replace traditional professional development experiences such as conferences, they can certainly provide additional ways to develop skills and expertise. Connecting with other librarians electronically through listservs, virtual conferences, and other online opportunities can make such involvement more accessible for new professionals. 相似文献

This article presents selected results from a study investigating the promotion of recreational reading in university libraries in the United Kingdom. An email questionnaire survey and follow-up interviews with a sample of respondents explored provision and attitudes toward recreational reading. The results suggest that recreational reading promotion is increasing in UK university libraries. Participants were positive about the benefits of recreational reading but they identified a number of barriers preventing them from increasing their activity including finance, staff time, and mission drift. The article concludes with recommendations for increasing recreational reading including the need for better staff awareness and training. 相似文献

ABSTRACTDeclining advertising revenue and print copy sales have propelled extensive paywall experiments in local newspapers to generate new revenue and fund local journalism. The success of these experiments is ultimately depending on whether or not they deliver the value that customers require. This article studies local newspapers’ potential to build successful paywalls by conducting a two-sided analysis of paywall value propositions and local news audiences’ responses to these value propositions. Drawing on mixed methods – in-depth interviews with 20 newspaper managers and a national survey (N = 1586) among local newspaper audiences – our study identifies a major gap between intended value of paywalls and customer value perception and behavior. These are misalignments between the intended attractiveness of paywalled content and audience attitude toward this content, and misalignments between access to paywalled content and use. Local newspapers’ offerings are particularly misaligned with younger, lower income and lower news interest customers. When these groups hit a paywall, they most likely bounce off. 相似文献

Pupils' responses in Grade 6 to a 40‐item questionnaire originally constructed to reveal different school attitudes were re‐analysed using recently developed techniques for latent variable analysis of two‐level data. One aim was to test a model for investigation of classroom environment and another aim was to compare exploratory factor analysis and confirmatory factor analysis when applied at individual and class levels. When using confirmatory factor modelling a separation of the individual and class‐level influences on the between‐group matrix was obtained. At class level three factors could be justified: Teachers and Teaching, Social Relations in Classrooms and Work Atmosphere in Classrooms. We conclude that the present analysis encourages further use of this type of questionnaire when investigating pupils' attitudes in a large number of classes. Two‐level latent variable analysis is useful for comparing pupils' attitudes within and between classes 相似文献

This paper examines the perceptions and understandings of ten grades 1 and 2 Singapore mathematics teachers as they learned to use clinical interviews (Ginsburg, Human Development 52:109–128, 2009) to understand students’ mathematical thinking. This study challenged teachers’ pedagogical assumptions about what it means to teach for student understanding. Clinical task-based interviews opened a window into students’ knowledge, problem-solving and reasoning, and helped teachers reflect on their teaching and assessment of student learning. Teachers also learnt about what it means to establish a culture of thoughtful questioning in the classroom and developed an emerging awareness that this requires a readiness to hear students’ ideas and connect informal or invented strategies with classroom mathematics. 相似文献
