Handedness has been studied for association with language-related disorders because of its link with language hemispheric dominance. No clear pattern has emerged, possibly because of small samples, publication bias, and heterogeneous criteria across studies. Non-right-handedness (NRH) frequency was assessed in N = 2503 cases with reading and/or language impairment and N = 4316 sex-matched controls identified from 10 distinct cohorts (age range 6–19 years old; European ethnicity) using a priori set criteria. A meta-analysis (Ncases = 1994) showed elevated NRH % in individuals with language/reading impairment compared with controls (OR = 1.21, CI = 1.06–1.39, p = .01). The association between reading/language impairments and NRH could result from shared pathways underlying brain lateralization, handedness, and cognitive functions.  相似文献

Ten pupils with moderate learning difficulties worked on a series of mathematics related activities while visiting a school providing a whole range of multi-media. The investigation suggests that IV has a particular contribution to make in meeting special educational needs. In addition to specific benefits in the teaching and learning of mathematics, the technology proved to be a facilitator in the areas of geography and life skills. There was also some evidence to suggest that IV can help to raise self-esteem, provide equal opportunities and support collaborative learning. Sense of ownership, language development and motivational characteristics, together with the promotion of attention and the accompanying benefit for teachers of the reduction of anxiety over discipline, are other factors suggesting the usefulness of the medium in this context.  相似文献

Philip Pullman grew up in what was then Southern Rhodesia, in Australia and in North Wales. He took an English degree at Oxford, and taught in middle schools in that city for thirteen years. He now divides his time between writing and lecturing at Westminster College, Oxford. His novelThe Ruby In The Smoke, the first part of a trilogy, won the International Reading Association Children's Book Award in 1988, and the other parts both made the ALA Best Book for Young Adults list. He has also written two illustrated novels for younger readers, books for teenagers and an adult novel.  相似文献
