Indirect effects of preschool classroom indexes of teacher talk were tested on fourth-grade outcomes for 57 students from low-income families in a longitudinal study of classroom and home influences on reading. Detailed observations and audiotaped teacher and child language data were coded to measure content and quantity of verbal interactions in preschool classrooms. Preschool teachers' use of sophisticated vocabulary during free play predicted fourth-grade reading comprehension and word recognition (mean age=9; 7), with effects mediated by kindergarten child language measures (mean age=5; 6). In large group preschool settings, teachers' attention-getting utterances were directly related to later comprehension. Preschool teachers' correcting utterances and analytic talk about books, and early support in the home for literacy predicted fourth-grade vocabulary, as mediated by kindergarten receptive vocabulary.

This article describes 2 points of view about the relationship between oral-language and literacy skills: The phonological sensitivity approach posits that vocabulary provides the basis for phonological sensitivity, which then is the key language ability supporting reading, and the comprehensive language approach (CLA) posits that varied language skills interact with literacy knowledge and continue to play a vital role in subsequent reading achievement. The study included 533 Head Start preschool-aged children (M ϭ 4 years 9 months) in 2 locations and examined receptive vocabulary, phonological awareness, and print knowledge. Partial correlational and regression analyses found results consistent with the CLA approach and evidence of a core deficit in phonological sensitivity, interpreted in a manner consistent with the CLA perspective.

HTA NIHR Health Technology Assessment ProgrammeT he Health Technology Assessment (HTA) programme, now part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the costs, effectiveness and broader impact of health technologies for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined to include all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care, rather than settings of care. The research findings from the HTA Programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component of the 'National Knowledge Service'. The HTA Programme is needs-led in that it fills gaps in the evidence needed by the NHS. There are three routes to the start of projects. First is the commissioned route. Suggestions for research are actively sought from people working in the NHS, the public and consumer groups and professional bodies such as ...

This study investigated the phonological awareness of low-income Spanish-English bilingual children, because phonological awareness has been found to be an important prerequisite for literacy acquisition and because such children have been identified as at risk for successful literacy acquisition. Our sample included 123 Spanish-English bilingual preschool children (M = 49.1 months) attending Head Start programs. Children's receptive vocabulary was assessed using the Peabody Picture Vocabulary Test3rd Edition and the Test de Vocabulario en Imagines Peabody. We assessed phonological awareness using English and Spanish versions of the Early Phonological Awareness Profile, which includes deletion detection and rhyming tasks. Emergent literacy was assessed in the child's stronger language using the Emergent Literacy Profile, which includes tests of environmental print knowledge, printed word awareness, alphabet knowledge, and early writing. Spring levels of phonological awareness in each language were most strongly related to development of phonological awareness in the other language. Final models accounted for 68% of the variance in spring English and Spanish phonological awareness. Educational implications are discussed.

Early childhood programs have long been known to be beneficial to children from low-income backgrounds, but recent studies have cast doubt on their ability to substantially increase the rate of children's academic achievement. This Review examines research on the role of language in later reading, describes home and classroom factors that foster early language growth, and reviews research on preschool interventions. It argues that one reason interventions are not having as great an impact as desired is because they fail to substantially change the capacity of teachers to support children's language and associated conceptual knowledge.
