Infants’ and Toddlers’ Television Viewing and Language Outcomes

Viewing data were reported every 3 months beginning at 6 months of age by the parents of 51 infants and toddlers. Viewing logs were coded for program, content, and intended audience. Using hierarchical linear modeling techniques, growth curves examining relationships between television exposure and the child’s vocabulary knowledge and expressive language skills were modeled. Parent’s education, child’s home environment, and child’s cognitive performance were statistically controlled. The findings support the importance of content and program type when describing media effects. At 30 months of age, watching Dora the Explorer, Blue’s Clues, Arthur, Clifford, or Dragon Tales resulted in greater vocabularies and higher expressive language scores; watching Teletubbies was related to fewer vocabulary words and smaller expressive language scores; watching Sesame Street was related only to smaller expressive language scores; and viewing Barney & Friends was related to fewer vocabulary words and more expressive language. Reasons for differences are discussed.

Recommended Outcomes for Families of Young Children with Disabilities.

The Early Childhood Outcomes (ECO) Center was funded by the Office of Special Education Programs to promote the development and implementation of child and family outcome measures for infants, toddlers, and preschoolers with disabilities. An evidence-based process with extensive stakeholder input led to the identification of five outcomes by which the effectiveness of services for families could be assessed: (a) families understand their childs strengths, abilities, and special needs; (b) families know their rights and advocate effectively for their child; (c) families help their child develop and learn; (d) families have support systems; and (e) families are able to gain access to desired services and activities in their community. These outcomes provide a framework by which states and the federal government could document whether early intervention and preschool programs are providing demonstrable benefits for families, and provide the basis for developing measurement systems to determine the extent to which such benefits have been attained.

Classwide Peer Tutoring: Teaching Students with Mild Mental Retardation in Inclusive Classrooms:

This study investigated the academic effects of classwide peer tutoring (CWPT) for students with mild mental retardation (MMR) and their typical peers in inclusive classroom settings. Four students with MMR were integrated in two, general education elementary classrooms during spelling instruction. Dependent measures included performance on weekly tests and direct observations of academic engagement. The results demonstrated increased spelling accuracy and increased levels of engagement for students with MMR and their typical peers during CWPT when compared to traditional teacher-led instruction, suggesting that CWPT is an effective instructional strategy for improving their spelling performance.

Assessing Children's Home Language Environments Using Automatic Speech Recognition Technology

The purpose of this research was to replicate and extend some of the findings of Hart and Risley using automatic speech processing instead of human transcription of language samples. The long-term goal of this work is to make the current approach to speech processing possible by researchers and clinicians working on a daily basis with families and young children. Twelve hour-long, digital audio recordings were obtained repeatedly in the homes of middle to upper SES families for a sample of typically developing infants and toddlers (N = 30). These recordings were processed automatically using a measurement framework based on the work of Hart and Risley. Like Hart and Risley, the current findings indicated vast differences in individual children’s home language environments (i.e., adult word count), children’s vocalizations, and conversational turns. Automated processing compared favorably to the original Hart and Risley estimates that were based on transcription. Adding to Hart and Risley’s findings were new descriptions of patterns of daily talk and relationships to widely used outcome measures, among others. Implications for research and practice are discussed.

General Growth Outcomes for Young Children: Developing a Foundation for Continuous Progress Measurement

Public expectations of accountability in our education system have increasingly focused on young childrens development, in part because of Goal 1 of the National Education Goals (By the year 2000, all children in America will start school ready to learn). Few sensitive measurement systems have been developed, however, to monitor young childrens growth over time. Building such a system requires a parsimonious but comprehensive set of developmental outcomes expected of children between birth and age 8. In the two studies presented here, investigators formulated a set of 15 general growth outcomes for young children, and conducted a survey of parents of children with and without disabilities and professionals in early childhood and early elementary education to validate the outcomes.

The Early Communication Indicator for Infants and Toddlers Early Head Start Growth Norms From Two States

The Early Communication Indicator (ECI) is a measure relevant to intervention decision making and progress monitoring for infants and toddlers. With increasing recognition of the importance of quality early childhood education and intervention for all children, measurement plays an important role in documenting children’s progress and outcomes of early educational experiences. Screening and progress-monitoring measures used in a response-to-intervention approach require age-based benchmarks for decision-making support. The goal of this study was to create a normative sample of ECI data referenced to children served by Early Head Start, including children with Individualized Family Service Plans (IFSPs). In a large sample of children (N = 5,883), program staff in 27 Early Head Start programs in two states collected ECI data from 2002 to 2007. Results indicated that children’s ECI total communication growth was conditional on IFSP status but not on gender or home language (English versus Spanish). Children’s patterns of communication on the ECI key skill elements (i.e., gestures, vocalizations, single words, and multiple words) were also conditional on IFSP status. Children with IFSPs had (a) later ages of onset for vocalizations, single words, and multiple words; (b) generally slower growth over time; and (c) significantly lower mean levels in the most advanced key skill: multiple words at 36 months of age. Implications for early childhood researchers and service providers are discussed.

The Use of Individual Growth and Developmental Indicators for Progress Monitoring and Intervention Decision Making in Early Education.

Progress monitoring tools have been shown to be essential elements in current approaches to intervention problem-solving models. Such tools have been valuable not only in marking individual childrens level of performance relative to peers but also in measuring change in skill level in a way that can be attributed to intervention and development. As such, progress monitoring measures have been central to Response to Intervention (RtI) approaches. In early childhood, progress monitoring measures have only recently been applied to the process of intervention decision-making. The purpose of this article is to describe Individual Growth and Developmental Indicators, contrast them with existing approaches to assessment in early childhood, and illustrate how they can be used within a larger problem-solving model to guide intervention decisions for infants and toddlers.

Effects of Web-Based Support on Early Head Start Home Visitors' Use of Evidence-Based Intervention Decision Making and Growth in Children's Expressive Communication.

We investigated Early Head Start home visitors’ use of evidence-based practices and the efficacy of a web-based system to support these practices. Home visitors learned to use 3 evidence-based practices: (a) frequent assessment of childrens early communication for screening and progress monitoring, (b) 2 home-based language-promoting interventions, and (c) data-based decision making in the use of the language-promoting intervention strategies. Two conditions were compared in a randomized control trial. Condition A involved the use of an online data collection system, training in data-based intervention decision making, and training in the evidenced-based language interventions. Condition B was the same as A plus additional web-based support (MOD: Making Online Decisions) linked to the childrens expressive communication data. Results indicated that the expressive communication of children receiving MOD support grew significantly more than for children whose home visitors did not receive MOD support. Home...

Academic and environmental effects of small group arrangements in classrooms for students with autism and other developmental disabilities

The use of small group instructional formats with children who have autism and developmental disabilities has received mixed results in the research literature (Reid & Favell, 1984). The purpose of the two studies reported herein was to address this controversy by comparing the performance of students in one-to-one instruction to those transitioned to small groups for a variety of teachers, students, settings, and under different training circumstances. In the first study, 41 students, ranging in age from 5 to 21 years old, from six classrooms, participated; and 25 students from six classrooms participated in the second study. Measures of environmental effects included academic gains via pre- and posttests, on-task and self-stimulatory behavior levels, correct responding, and frequencies of teacher behaviors during both one-to-one and small group formats. Results of both experiments indicated that students were able to successfully transition to small group formats across several curriculum areas including language, math, readiness, and shopping. Further, experienced teachers and administrators were able to train a second group of staff to use the small group procedures effectively. The successful application for this number of students and teachers within natural learning environments is unprecedented and provides important documentation for both the utility and practicality of small group instruction with students who have developmental disabilities.

A Web-Based Tool to Support Data-Based Early Intervention Decision Making

Progress monitoring and data-based intervention decision making have become key components of providing evidence-based early childhood special education services. Unfortunately, there is a lack of tools to support early childhood service providers’ decision-making efforts. The authors describe a Web-based system that guides service providers through a decision-making process informed by child performance on Infant and Toddler IGDIs (Individual Growth and Development Indicators), the provider’s professional judgment, and information from the child’s primary caregiver. Using a case example, the authors describe how a service provider integrates the system into an existing service delivery model. Finally, they describe barriers and potential solutions to implementation within the context of a traditional early childhood service delivery model and implications for policy and practice.
