Research Findings: This study examined how teacher–child conversations unfold during shared book reading in Head Start classrooms as well as the relations between that talk and children’s vocabulary learning. Book reading experiences in 27 Head Start classrooms were videotaped and coded for teacher talk, child responses, teacher follow-up remarks, and teacher wait time; we also assessed children’s vocabulary learning. Findings indicated that Head Start teachers infrequently asked open prompts or provided book-related comments; the predominant tool used in shared reading was the closed prompt. Teachers generally accepted 1 answer per question, and children’s answers were nearly always correct. Wait time was rarely observed. Across the sample, more child talk was predictive of stronger child vocabulary learning. For children with low initial vocabulary skills, learning was also linked to more expository comments by teachers. Practice or Policy: Findings help to map out the sequence of instructional events that make up preschool classroom conversations and provide insight into potential levers for improvement. 相似文献

Forty‐four Head Start classrooms were randomly assigned to enriched intervention (Head Start REDI—Research‐based, Developmentally Informed) or “usual practice” conditions. The intervention involved brief lessons, “hands‐on” extension activities, and specific teaching strategies linked empirically with the promotion of: (a) social‐emotional competencies and (b) language development and emergent literacy skills. Take‐home materials were provided to parents to enhance skill development at home. Multimethod assessments of three hundred and fifty‐six 4‐year‐old children tracked their progress over the course of the 1‐year program. Results revealed significant differences favoring children in the enriched intervention classrooms on measures of vocabulary, emergent literacy, emotional understanding, social problem solving, social behavior, and learning engagement. Implications are discussed for developmental models of school readiness and for early educational programs and policies. 相似文献

Research findings. Language development subcontexts within 20 Head Start classrooms were studied by observing teachers' child-directed talk during free play, mealtime, and book reading. In each context, observers coded all child-directed statements, directives, and questions, noted instances of pretend talk and decontextualized talk, and rated the richness and sensitivity-responsiveness of teachers' talk. Rates of child-directed talk were similar across contexts, but the challenging features of teachers' talk varied substantially across contexts: pretend talk occurred almost exclusively during free play, decontextualized talk was most common during mealtime, and ratings of richness were greatest during book reading. Higher rates of pretend talk and decontextualized talk and higher ratings of richness were associated with higher ratings of sensitivity-responsiveness. Rates of child-directed talk did not differ reliably for Lead Teachers and Assistant Teachers. Implications for practice. Professional development efforts may focus productively on helping Head Start teachers to recognize natural opportunities for different types of challenging talk in different classroom contexts. In the majority of classrooms, encouraging teachers to engage in more child-directed talk carries little risk of reducing the quality of sensitive-responsive caregiving. Assistant Teachers play a major role in Head Start classroom language environments and should be included in professional development activities focused on children's language skills. 相似文献

AbstractLittle analytical scrutiny has been devoted to teacher accommodation of academic language at the early childhood level, despite being a critical school-level factor to consider when addressing at-risk learners’ academic needs. The present study investigates how fifteen Head Start teachers support three components of academic language during whole-class read-alouds of narrative storybooks: academic vocabulary, conceptual knowledge, and complex syntax. Pairing a corpus-based analysis of linguistic features and content analyses of teachers’ extratextual utterances, we describe teachers’ strategies for accommodating at-risk children’s early experiences with linguistically and syntactically complex texts. Our findings indicate that teachers simplified the language of the texts to accommodate student need, while also providing examples of academic talk through defining terms and providing conceptually-rich talk. Although teachers provided rich support for academic vocabulary, less accommodation was made for complex syntax. Practical and theoretical implications are addressed. 相似文献

The current study examined whether cumulative family risk would moderate the relation between regularity of attending Head Start and three child outcomes: receptive vocabulary, teacher ratings of social competence, and teacher ratings of following instructions. Cumulative family risk was the sum of four dichotomous measures: low income, low cognitive stimulation, intrusiveness, and depression. Participants were 94 Head Start children and their caregivers. All but 1 of the 16 classrooms attended were rated as good or better on the Early Childhood Environment Rating Scale (ECERS). Analyses revealed the relation between Head Start attendance and receptive vocabulary was moderated by cumulative risk, with children from higher risk families benefiting more. Regardless of cumulative family risk, attendance predicted teacher ratings of social competence; regardless of attendance, cumulative family risk predicted teacher ratings of following instructions. Results are interpreted as supporting a compensatory model of the impact of Head Start on children’s receptive vocabulary and the use of attendance as a measure of the “value added” by Head Start. Public policy implications are discussed. 相似文献

Research Findings: Mental state verbs (MSV), a component of literate and academic language, may facilitate vocabulary growth, as they relate to metacognitive and metalinguistic awareness as well as decontextualized talk, all of which have been associated with vocabulary growth. In this study, we examined teacher MSV use in group content instruction and book reading in Head Start classrooms (N = 49) to determine the prevalence of teachers’ use of MSV. We sought to determine whether there was an association between teachers’ MSV use and children’s (N = 402) receptive and expressive vocabulary scores across 1 year of preschool. Results from hierarchical linear modeling revealed that teachers’ use of MSV in group content instruction was positively associated with children’s end-of-year receptive, but not expressive, vocabulary scores. No significant relations emerged for book reading. Positive associations between MSV in which the child was the referent of the verb and children’s receptive vocabulary were found, which indicates a potential scaffolding effect. Practice or Policy: Results indicate that teachers should consider including MSV in their content-rich instruction and provide support by placing the child as the referent of the verb. Additional instructional implications are addressed. 相似文献

This study explored relationships between characteristics of classroom talk exposure and immigrant first graders' acquisition of second language oral skills (vocabulary and listening comprehension) and literacy skills. Twenty‐six children (mean age = 6.10 years) with Turkish as their first language and Norwegian as their second, attending various multilingual and ethnically diverse classrooms in Norway, were videotaped during classroom conversations. Classroom talk was coded for vocabulary richness, discursive complexity and emergent phonics talk and the children's oral language and literacy skills were assessed. Classroom vocabulary richness and discursive complexity predicted the children's second language vocabulary skills and listening comprehension after controlling for maternal education, but did not predict their literacy skills. The density of emergent phonics talk did not predict target children's code‐related skills in this sample. Applied perspectives related to second language learning in multiparty settings are discussed. 相似文献

This study examined the ways in which the language that Head Start teachers used during book reading, as well as the extent to which they made explicit connections between book reading and other instructional activities, were linked to preschoolers' vocabulary development. Participants included 10 Head Start teachers and 153 children in their classrooms. Research Findings: Analyses revealed that teachers varied substantially in the frequency and nature of their book-related remarks, and connections between books and the broader curriculum were relatively few in number and constrained in nature. On average, children learned more words over the course of the year when teachers used more contextualized and decontextualized talk during book readings. Contextualized book-related talk was most positively associated with learning among children with relatively low initial vocabulary knowledge. Too few connections between book reading and the curriculum were observed to afford analysis of their contributions to children's vocabulary skills. Practice or Policy: The findings show the nuanced ways in which shared book reading, a critical part of the preschool day, is linked to vocabulary growth among the nation's most vulnerable learners. The results also highlight potential avenues through which readings could be strategically individualized to optimize early vocabulary development. 相似文献

The purpose of this study was to describe the characteristics and findings of an early literacy intervention program implemented to facilitate the development of critical emergent literacy skills among children identified as low-income and at-risk in the context of collaborative, pre-kindergarten/Head Start classrooms. Using data from a sample of pre-Kindergartners (n = 154), the intervention reveals the effectiveness of early literacy intervention in the areas of vocabulary, phonological awareness, and print knowledge. The study suggests the possibility of preventing literacy delays and referrals for specialized, special education services for young children through early intervention at the preschool level. 相似文献

This study examined the quality of preschool teachers’ interactive conversations with three- and four-year-olds in two Head Start classrooms serving children from low-income families in the United States. Over a period of 20?weeks, 10 bi-weekly observations of conversations (totaling 15?h per classroom) were conducted in one small-group (Play Time) and two large-group (Breakfast Time and Circle Time) contexts. The teacher–child verbal interactions were transcribed and coded using the Teacher Interaction and Language Rating Scale (TILRS) to determine the frequency of responsive language strategies employed by the teachers across the three contexts. The two teachers applied Child-Centered Strategies and Interaction-Promoting Strategies the most during Circle Time, followed by Play Time, and the least during Breakfast Time. While it was observed that both teachers did talk to the children face to face frequently across contexts, they rarely used Language Modeling Strategies to engage them in cognitively challenging conversations. Implications for professional development are discussed. 相似文献

Creating opportunities for children to apply newly learned vocabulary in meaningful contexts is an important aspect of supporting vocabulary development. However, previous research has not adequately examined how this can be accomplished in preschool classrooms. To address this issue, we explored using story dictation to support preschoolers’ expressive vocabulary development. Thirteen children in a Head Start classroom were videotaped dictating a total of 38 stories. Scribed stories and videos of story dictation sessions were analyzed both qualitatively and quantitatively to examine the outcomes and process. Results indicated that children used and learned target vocabulary during story dictations, and that target word use increased in number and complexity over time. How the teacher supported story dictations and target word use is discussed. 相似文献

This study examined the efficacy of using different types of mobile media apps to increase the receptive and expressive vocabulary development of 3-, 4-, and 5-year-old preschool children living in economically disadvantaged communities. Children and teachers in four Head Start classrooms participated in the quasi-experimental study, which included an 8-week intervention in which the children interacted with one of two types of apps: one classroom used four scaffolding-like vocabulary apps for an average of 1.8 h per day (n?=?16) and one classroom used four open-ended vocabulary apps for an average of 1.3 h per day (n?=?15). Two classrooms served as comparison groups (n?=?18; n?=?14) which used apps that were chosen by the Head Start program with no specific instructional method for approximately 1 h per day. Children’s vocabulary was assessed pre- and post-intervention using the PPVT-4, the EVT-2, and iPad Receptive and Expressive Vocabulary Assessments. Using a repeated measures analysis of variance with split plot analysis, children who used scaffolding-like vocabulary apps performed statistically significantly higher on the PPVT-4 than children who used open-ended vocabulary apps. There were no significant differences between groups on the EVT-2. The study contributed to the literature on teacher instruction of utilizing scaffolding-like apps to increase preschool vocabulary knowledge. 相似文献

This study uses data collected in the intervention classrooms (N = 22) of Head Start REDI (Research-based, Developmentally Informed), a randomized clinical trial testing the efficacy of a comprehensive preschool curriculum targeting children's social-emotional competence, language, and emergent literacy skills delivered by teachers who received weekly coaching support. Multiple dimensions of implementation (Dosage, Fidelity, Generalization, and Child Engagement) were assessed across curriculum components. Results indicated that REDI Trainers perceived significant growth in teacher implementation quality over time but that patterns differed by implementation dimension. Dosage and Fidelity of all intervention components were high at the beginning of the year and remained so over time while Generalization was low at baseline but increased significantly across the year. Variation in implementation was associated with variation on several child outcome measures in the social-emotional domain but not in the language and literacy domains. 相似文献

This study used data from the Head Start Family and Child Experiences Survey (FACES) 2009 4-year-old cohort to examine associations among family characteristics, home and classroom environments, and the emergent literacy skills of Head Start children. Results from hierarchical linear models suggest that both family and classroom contexts play a unique and interactive role in supporting Head Start children's development of different sets of emergent literacy skills. Parental warmth was positively related to children's oral language skills (i.e., receptive and expressive vocabulary knowledge), and teachers' educational level and the quality of instructional support in the classroom were significantly associated with children's code-related skills (i.e., letter-name and letter-sound knowledge). Further, high-quality instructional support in the classroom buffered the negative influence of low maternal education on children's oral language skills. Interventions focusing on enhancing the quality of parent-child interactions, in addition to professional development for teachers designed to improve the quality of instructional support, may contribute to promoting the development of emergent literacy skills of young children from low-income families. 相似文献

The purpose of this study was to examine the impact of the mentor–coach initiative model on participating Head Start Programs.
The researchers interviewed 44 participants across two mid-western states. The participants provided positive feedback about
the initiative and identified specific literacy practices based on this model that were successfully implemented in their
classrooms. Evidence from this study suggests the importance of incorporating the mentor-coaching initiative model to enhance
teacher pedagogical practices. 相似文献
