Converging evidence from a number of neuroimaging studies, including our own, suggest that fluent word identification in reading is related to the functional integrity of two left hemisphere posterior systems: a temporo-parietal system and a ventral occipito-temporal system. These posterior systems are functionally disrupted in developmental dyslexia. Reading disabled, relative to nonimpaired, readers demonstrate heightened reliance on both inferior frontal and right hemisphere posterior regions, presumably in compensation for the LH posterior difficulties. We propose a neurobiological account suggesting that for normally developing readers the temporo-parietal system predominates at first, and is associated with aspects of processing critical in learning to integrate orthography with phonological and lexical-semantic features of printed words. The occipito-temporal system, by contrast, constitutes a fast, late-developing, word-identification system that underlies fluent word recognition in skilled readers.  相似文献

School media specialists must be teachers, leaders, and advocates for reading, inquiry, and learning. Partnering with classroom teachers, they must design and implement curriculum and instruction that prepare young citizens for a life that requires thinking, inquiry, problem-solving and ethical behavior. These experiences provide the foundation for all content-area learning. In order to be prepared for a constantly changing environment, professionals need to revisit, reframe, and re-imagine knowledge, skills, attitudes, and dispositions. In this article, the author presents six tools that form a media specialist’s palette to help them meet these challenges. Along with these tools, specific ideas and examples are presented that illustrate how this palette of tools can be used in the media center on a daily basis.  相似文献

OBJECTIVES: Funded by Research in the Workplace Award (RIWA) 2001, the study investigated the information needs and use of NHS library services by members of the West of Scotland Colorectal Cancer Managed Clinical Network (MCN), a single subject, cross boundary, multi-professional organization. METHOD: A postal questionnaire sent out in October 2002 was returned by 100 members and follow-up interviews were held in March 2003 with 11 of the respondents. The questions related to access to resources, library services such as literature searches, current awareness and training. They also explored the use of electronic resources and the Internet. RESULTS: Respondents were mainly hospital doctors and a few nurses from across five health boards. Most had access to a library, although not all made use of it, possibly an indication of the need for improved communications between librarians and health-care staff. Generally, research and professional development were reported as reasons for needing cancer information, but on further investigation the motivation to conduct literature searches was more related to patient care. Examples included treatment of unusual cases, locating information for patients and identifying guidelines. There are indications of unmet needs for local contact information and evaluated patient information. CONCLUSION: Development of a cancer portal within the NHS Scotland e-Library available from May 2004 based on the Managed Knowledge Network (MKN) concept is attempting to address many of the issues raised in the survey, including inequities of access to services and signposting to a variety of types of information.  相似文献

Learning communities have been present in community college settings for more than a decade. The literature suggests that they are generally effective for both participating students and faculty. As economic development increasingly demands greater technological sophistication, and community colleges are faced with increasing numbers of developmentally challenged students, learning communities may be one means to effectively resolve this paradox. This article is directed to those faculty and staff who may be considering the initiation of a learning community. It provides a review of literature, and presents a set of issues currently being addressed at one small community college in Louisiana where a learning community is in the design stage.  相似文献

The purpose of this study was to describe and understand the range of outcomes of class visits to natural history museums. The theoretical framework is based on the multifaceted process of learning in free choice learning environments, and emphasizes the unique and individual learning experience in museum settings. The study’s significance is in highlighting several possible cognitive as well as non-cognitive learning effects in museums class visits, by providing the student’s point of view. Data was collected by semi-structured interviews with 50 students in grades 6–8 on the day following the visit. We present evidence that students expressed several learning outcomes, connected directly and indirectly to the scientific content of the visit. Content oriented outcomes included acquiring scientific knowledge and making connections to prior knowledge; social oriented outcomes were identified in students’ statements regarding communicating knowledge and social aspects of learning; and interest oriented outcomes were evidenced by students’ expressions about emotions, interest and curiosity. The aggregate data addressed the common outcomes and the impact of class visits to natural history museums in the short term. Comparisons between two types of museums show significant differences in several aspects, regarding the exhibit and/or the activity type. Practical ideas for structuring the ultimate experience are included.  相似文献

Alphabetic orthographies vary in the (in)consistency of the relations between spelling and sound patterns. In transparent orthographies, like Italian, the pronunciation can be predicted from the spelling, in contrast to opaque orthographies such as English, where spelling–sound correspondences are often inconsistent. The pronunciation of English vowel letters is in particular very ambiguous. In this paper, we provide a cross-linguistic investigation of orthographic transparency at the word-initial letter–phoneme level, resulting in ranked metrics for the seven languages investigated- Dutch, English, French, German, Hungarian, Italian, and Portuguese, expressed as entropy values. We focus on the contributions of vowels and consonants towards the overall orthographic transparency and provide evidence that deviations from consistent word-initial 1:1 mappings between letters and phonemes influence reaction times in naming tasks. Implications for theories of visual word recognition and speech production will be discussed.  相似文献

ABSTRACT:  This article explores the civic republican conception of citizenship underlying the Labour government's programme of civil renewal and the introduction of education for democratic citizenship. It considers the importance of the cultivation of civic virtue through political participation for such developments and it reviews the research into how service learning linked to character education can lead to the civic virtue of duty or social responsibility.  相似文献
