The project reported here was designed to explore the cognitive style used by pupils with dyslexia when answering a range of mathematical questions. The research involved 132 pupils aged between 9 and 13 years, including 66 pupils in mainstream and 66 pupils in specialist schools, in three countries in Europe.
Detailed studies of the methods used by pupils attempting the given questions on a test of cognitive style suggested that they fell into two main categories. These pupils were observed when completing the test and their responses were categorised accordingly. The resulting numerical data were then analysed for differences between pupils within each country and between their non-dyslexic counterparts.
The results showed significant differences in the balance of cognitive styles employed by pupils with dyslexia as opposed to their non-dyslexic counterparts. Also there were interesting differences occurring between the pupils with dyslexia within the three countries on initial testing. Further differences were established after a six-month intervention period, suggesting that the characteristics of different curriculum models do have an impact upon pupils' flexibility as learners. 相似文献

Peer moderation of group work in higher education is rapidly advancing through the use of technological developments and is increasingly being informed by pedagogical research. The highly successful WebPA online assessment system has gone through a number of development phases over its 15-year history and has now evolved into a relatively mature and flexible tool for facilitating group work. This paper presents a case study of the approaches that have been used in the system's development from the technical perspective, and describes how the scope of the project has massively expanded and that the development has been continually backed by a sound and wide-ranging pedagogy. The benefits of using the online system are shown to be underpinned throughout by examples of good practice in the supervision of academic group work. A critical evaluation of the tool and surrounding pedagogical practices highlight future areas for technical expansion. 相似文献

A study carried out for the UK Joint Information Systems Committee examined models for the provision of access to material in institutional and subject‐based archives and in open access journals. Their relative merits were considered, addressing not only technical concerns but also how e‐print provision (by authors) can be achieved – an essential factor for an effective e‐print delivery service (for users). A ‘harvesting’ model is recommended, where the metadata of articles deposited in distributed archives are harvested, stored and enhanced by a national service. This model has major advantages over the alternatives of a national centralized service or a completely decentralized one. Options for the implementation of a service based on the harvesting model are presented. 相似文献

An assessment of social sciences coverage by four prominent full-text online aggregated journal packages 总被引:1,自引:0,他引:1
The cost effectiveness and quality of full-text journals are analyzed for four prominent online aggregated journal packages: EBSCOhost Academic Search FullTEXT, UMI Proquest Direct Periodicals Research II, IAC’s Expanded Academic ASAP, and H.W. Wilson’s OmniFile. Price data from EBSCO’s Librarians’ Handbook are used to assess the total and average value of social sciences journals in each package. Quality of social sciences journals coverage is compared based on citation impact factors as recorded in Journal Citation Reports—Social Sciences Edition. 相似文献

Precision prediction based on ranked list coherence 总被引:1,自引:0,他引:1
We introduce a statistical measure of the coherence of a list of documents called the clarity score. Starting with a document list ranked by the query-likelihood retrieval model, we demonstrate the score's relationship to query ambiguity with respect to the collection. We also show that the clarity score is correlated with the average precision of a query and lay the groundwork for useful predictions by discussing a method of setting decision thresholds automatically. We then show that passage-based clarity scores correlate with average-precision measures of ranked lists of passages, where a passage is judged relevant if it contains correct answer text, which extends the basic method to passage-based systems. Next, we introduce variants of document-based clarity scores to improve the robustness, applicability, and predictive ability of clarity scores. In particular, we introduce the ranked list clarity score that can be computed with only a ranked list of documents, and the weighted clarity score where query terms contribute more than other terms. Finally, we show an approach to predicting queries that perform poorly on query expansion that uses techniques expanding on the ideas presented earlier.
