This study examined literacy instruction in 14 first‐grade classrooms of English learners (ELs) in three schools in a large urban school district in southern California over a two‐year period. Pre‐ and posttest measures of oral‐reading fluency for 186 first graders, representing 11 native languages, were the outcome data. Reading‐fluency data were examined in reference to ratings of literacy practices using the English Learners Classroom Observation Instrument (ELCOI). Results indicated a moderately strong correlation (r= 0.65) between ELCOI rating and gain in oral‐reading fluency at the end of first grade. We report patterns of ELs who read below the oral‐reading fluency benchmark thresholds and patterns of students who were ultimately labeled with learning disabilities. Instructional practices of teachers rated “high” and “low” are discussed. Educational implications and recommendations for future research are discussed.  相似文献

Three languages are widely used in schools in Kenya – English, Kiswahili and Kenya Sign Language. Many pupils with hearing impairments are taught separately from the mainstream, in specialist settings. The fact that most of the formal teaching, assessment and examination processes in Kenyan schools rely upon spoken and written English compounds the separation of these pupils from the mainstream of education and, potentially, from the mainstream of society. In this article, Gertrude Wamae, graduate assistant in the Department of English and Linguistics at Kenyatta University, and Rachael Kang'ethe-Kamau, lecturer in the Department of Special Education at Kenyatta University, discuss the relationships between language, hearing impairment and inclusion in the Kenyan context. The article suggests that the use of signed exact English would enhance opportunities for inclusion for those with hearing impairments and that programmes of teacher training need to take account of persuasive research in this area. The article closes with a plea for further research, carried out collaboratively by educationalists, linguists, teacher trainers and practitioners, to develop policies and practices suited to more inclusive futures. The article is based on a paper presented to the International Conference on Inclusive Education run by Maseno University in September 2002.  相似文献

The aim was to examine cross-cultural variation in linguistic responsiveness to young children in 10 English-speaking mother–child dyads and 10 Italian-speaking mother– child dyads. All 20 children were late talkers who possessed delays in expressive vocabulary development but age-appropriate cognitive and receptive language skills. Dyads were filmed in 15 minute free play contexts, which were transcribed and coded for measures of maternal linguistic input (e.g. rate, MLU, labels, expansions) and child language productivity (e.g. utterances, different words used). The results revealed that the Italian mothers used more utterances, spoke more quickly and used a more diverse vocabulary than the Canadian mothers. The Italian children mirrored their mothers and also used more utterances and a more diverse vocabulary than the Canadian children. Mothers in both groups used similar percentages of responsive labels and expansions. However, Italian mothers responded to fewer of their children's vocalisations, using a smaller percentage of imitations and interpretations than the Canadian mothers. Correlations between maternal input and children's language productivity revealed that contingent language measures (e.g. imitations, interpretations, expansions) were related to high levels of productivity in children in both cultural groups. The results support the use of language interventions based on increasing maternal responsiveness for these children at the one-word stage of language development. They also point to differences that may be culturally based. For example, Italian mothers use faster rates of interaction and appear to have higher expectations for their children's verbal participation in interaction. This is reflected in higher rates of language production from their children, even though children in both cultural groups have similar vocabulary sizes.  相似文献
