Understanding Child-Directed Speech Around Book Reading in Toddler Classrooms: Evidence From Early Head Start Programs.

Child-directed speech (CDS), which can help children learn new words, has been rigorously studied among infants and parents in home settings. Yet, far less is known about the CDS that teachers use in classrooms with toddlers and children's responses, an important question because many toddlers, particularly in high-need communities, attend group-care settings. This exploratory study examines the linguistic environment during teacher-led book readings in American Early Head Start classrooms serving 2-year-olds from households in poverty. Seven teachers in four classrooms were trained to emphasize target words while reading story and informational books. We first analyzed the nature and quality of their book readings from a macro-level, exploring global instructional quality [Classroom Assessment Scoring System (CLASS)] and linguistic complexity [i.e., diversity of vocabulary (D) and sophistication of syntax (MLU-w)], and we also examined micro-level teacher-child talk strategies and use of target words. Compared to prior research, these classrooms had similar global quality and syntactic complexity, although less lexical diversity. Exploratory results also revealed three distinct teacher talk patterns-teachers who emphasized (1) comments, (2) questions, and (3) a balance of the two. Question-focused teachers had more adult and child talk during reading, as well as more repetitions of target words, and stronger CLASS Engaged Support for Learning. However, comment-focused teachers used more diverse vocabulary and had stronger CLASS Emotional and Behavioral Support. Results illuminate the nature and quality of CDS in toddler classrooms, particularly in the context of an intervention emphasizing target vocabulary words, and highlight applications for professional development and questions for further research.

Vocabulary learning in Head Start: Nature and extent of classroom instruction and its contributions to children's learning.

In the current study, we employed the 2006 cohort of the large-scale, nationally representative, Head Start Family and Child Experiences (FACES) dataset to construct a snapshot of vocabulary instruction and learning in high-poverty preschools. Specifically, we examined Head Start teachers' reports of the frequency of vocabulary instruction in their classrooms as well as the overall quality of their classroom instruction. We also explored the teacher- and center-level factors that predicted these dual aspects of instruction, and the role of that instruction in children's vocabulary development over the preschool year. Participants included 293 teachers in 116 Head Start centers, as well as 2501 children in their classrooms. Results showed that, whereas there was notable variation, most teachers reported providing a variety of vocabulary-focused instructional activities nearly every day. The quality of their classroom instruction was generally modest. Classroom instructional quality was predictive of children's vocabulary learning, with stronger relations apparent for children with lower initial skills and for classrooms with higher quality instruction. The frequency of instruction in vocabulary was not related to children's word learning. Results provide new descriptive data about the state of vocabulary instruction in Head Start preschools and highlight both areas of success and opportunities for additional support.

A social model for health promotion for an aging population: initial evidence on the Experience Corps model.

This report evaluates whether a program for older volunteers, designed for both generativity and health promotion, leads to short-term improvements in multiple behavioral risk factors and positive effects on intermediary risk factors for disability and other morbidities. The Experience Corps(R) places older volunteers in public elementary schools in roles designed to meet schools' needs and increase the social, physical, and cognitive activity of the volunteers. This article reports on a pilot randomized trial in Baltimore, Maryland. The 128 volunteers were 60-86 years old; 95% were African American. At follow-up of 4-8 months, physical activity, strength, people one could turn to for help, and cognitive activity increased significantly, and walking speed decreased significantly less, in participants compared to controls. In this pilot trial, physical, cognitive, and social activity increased, suggesting the potential for the Experience Corps to improve health for an aging population and simultaneously improve educational outcomes for children.

Short-term impact of Experience Corps participation on children and schools: results from a pilot randomized trial.

This article reports on the short-term impact of a school-based program using older adult volunteers and aimed at improved academic achievement and reduced disruptive classroom behavior in urban elementary school students. The Experience Corps Baltimore (Maryland) program places a critical mass of older adult volunteers, serving 15 hours or more per week, in public schools to perform meaningful and important roles to improve the educational outcomes of children and the health and well-being of the volunteers. This article reports on the preliminary impact of the program on children in grades K-3. A total of 1,194 children in grades K-3 from six urban elementary schools participated in this pilot trial. At follow-up, third grade children whose schools were randomly selected for the program had significantly higher scores on a standardized reading test than children in the control schools, and there was a nonsignificant trend for improvement in alphabet recognition and vocabulary ability among kindergarten children in the program. Office referrals for classroom misbehavior decreased by about half in the Experience Corps schools, but remained the same in the control schools. Teachers had somewhat more favorable attitudes toward senior volunteers as a result of having older volunteers in the classroom, although the difference between the intervention and control schools was not statistically significant. In this pilot trial, the Experience Corps program led to selective improvements in student reading/academic achievement and classroom behavior while not burdening the school staff.

Experience Corps: design of an intergenerational program to boost social capital and promote the health of an aging society.

Population aging portends a crisis of resources and values. Desired solutions could include intergenerational strategies to harness the untapped potential of older adults to address societal needs and to generate health improvements for older adults. Despite the desire of many older adults to remain socially engaged and productive, the creation of productive roles has lagged. This report describes the conceptual framework and major design features of a new model of health promotion for older adults called Experience Corps. Experience Corps operates at, and leads to benefits across, multiple levels, including individuals, schools, and the larger community. At the individual level, we propose a model based on Erikson's concept of generativity to explain how and why Experience Corps works. At the level of schools, we propose a parallel model based on social capital. Experience Corps is a volunteer service program designed to improve the lives of urban children and to yield health improvement for older persons. It illustrates how population aging creates new opportunities to address difficult social problems. This article explores how the linkage of concepts at multiple levels motivates a potentially cost-effective, feasible, and high-impact program.
