Genetic influences in different aspects of language development: the etiology of language skills in 4.5-year-old twins     

Kovas Y  Hayiou-Thomas ME  Oliver B  Dale PS  Bishop DV  Plomin R 《Child development》2005,76(3):632-651

The genetic and environmental etiologies of diverse aspects of language ability and disability, including articulation, phonology, grammar, vocabulary, and verbal memory, were investigated in a U.K. sample of 787 pairs of 4.5-year-old same-sex and opposite-sex twins. Moderate genetic influence was found for all aspects of language in the normal range. A similar pattern was found at the low end of the distribution with the exception of two receptive measures. Environmental influence was mainly due to nonshared factors, unique to the individual, with little influence from shared environment for most measures. Genetic and environmental influences on language ability and disability are quantitatively and qualitatively similar for males and females.  相似文献   

Increasing cesarean birth rates: a clash of cultures?          下载免费PDF全文

Moore ML 《The Journal of perinatal education》2005,14(4):5-8

Cesarean birth rates in the United States reached a high of 27.6% in 2003, a 6% increase over 2002. A cultural conflict appears to exist between the views of those who believe that birth is normal and many cesareans are unnecessary and the views of those who feel that higher rates are justifiable. Childbirth educators can share cultural concepts of normal birth in their classroom.  相似文献   

Multiple Dimensions of Instructional Effectiveness in Reading: A Review of Classroom Observation Studies and Implications for Special Education Classrooms     

Yujeong Park  Mary T. Brownell  Elizabeth F. Bettini  Amber E. Benedict 《Exceptionality》2019,27(1):1-17

The purpose of this study was to review and analyze effective classroom reading practices for early graders, using information gathered from the existing content-general and content-specific observation protocols measuring teachers’ classroom reading practices. Dimensions and constructs from 28 observation studies were synthesized to identify classroom instructional practices that have positive impacts on student achievement. Findings revealed that (a) instructional support, emotional support, and classroom management have positive impacts on student achievement, (b) the degree to which instructional practices are effective depends on students’ particular learning needs, and (c) students’ entering skills and primary language are associated with instructional effectiveness in reading. Challenges and implications for future research on effective instructional strategies for special education and the development of an observational protocol for special education teacher effectiveness are discussed.  相似文献   

Moving Towards a Fair Start: equal gender opportunities and the careers service     

Bob Coles  Mary Maynard 《Gender and education》1990,2(3):297-308

Although there is now a considerable literature on gender inequality in education and employment, there is virtually no research on the Careers Service which provides a bridge between the two. Based on a national survey of all Careers Services conducted in 1987, this paper explores the significance afforded to gender discrimination and the nature and content of equal opportunities policies designed to counter it. It draws attention to the differences in meaning which the term ‘equal opportunities’ can have and to the changing context in which equal opportunities policies now operate.  相似文献   

Environmental print and word reading     

Virginia Cronin  Denise Farrell  Mary Delaney 《Journal of Research in Reading》1999,22(3):271-282

The nature of the earliest stage of reading was examined by comparing two views about the importance of environmental print in children’s learning experiences. One theory holds that environmental print leads to the acquisition of reading through developing rudimentary representations of specific words and logos, while the second theory concerns assembled phonology and asserts that reading begins with knowing letters and their sounds. Supporters of this theory hold that knowledge of environmental print and logos is reading the environment and may not directly facilitate the acquisition of word reading. Two studies were conducted with non-reading preschool children in which environmental print knowledge was assessed and related to word recognition training. In the first session of each study children were presented with accurate representations of environmental print and logos such as ‘McDonalds’ and ‘Stop’ to find the ones they were able to identify and the ones they failed to identify. In the second session learning trials were conducted with those words from the logos that the children identified and also those that they failed to identify and with matching control words. Both studies found that the words from the known logos were more readily learned than the matching control words, but only in Study 1 were the known logo words learned more readily than the ones the children did not know. The results were discussed in terms of Gibson’s (1969) theory of perceptual learning, and supported the view that environment print and logo knowledge facilitated word reading.  相似文献

Topicalization and the Processing of Expository Prose by Children: mediating effects of cognitive styles and content familiarity     

Beth Davey  Debra Miller 《教育心理学》1990,10(1):23-38

This study assessed the effects of text topicalization conditions (initial position, final position, or no topic sentence) on the comprehension of main ideas and specific passage information for middle school readers. Also of interest were interactions of topic familiarity and readers’ cognitive styles (degree of field independence) with text topicalization. One hundred and seven subjects were randomly assigned to one of the three topicalization conditions and read three familiar and three less‐familiar multipleparagraph expository texts. Main idea comprehension was assessed with both a sentencesummary (generation) and best‐title (recognition) task. Comprehension of specific passage information was evaluated with multiple‐choice items. Text topicalization effects were observed for main idea comprehension (with initial position best, followed by final position), while topic familiarity resulted in higher comprehension scores for specific passage information. Moreover, a cognitive style‐text topicalization interaction was found on the best‐title task; in this case, relatively field dependent readers were assisted by a final topic sentence placement. Implications are drawn for future research concerning the complex interplay of texts, tasks and readers in prose‐processing.  相似文献
