A mixed methods, cluster randomized control trial to examine assistive technology use to support early literacy in preschool children with disabilities.

This mixed methods study examined the impact of a multi-faceted professional development (PD) program for preschool teachers and classroom assistants on teacher-supported assistive technology (AT) use and early literacy development of children with disabilities. Four special education preschools were randomized into intervention (2 schools, 9 teachers, 50 children) and waitlist control (2 schools, 17 teachers, 42 children) groups. The 24-week PD included online modules, coaching, and AT device kits.

Putting the child in the driver's seat: Insights into language development from children's interactions in preschool classrooms.

Children's own language production has a role in structuring the language of their conversation partners and influences their own development. Children's active participation in their own language development is most apparent in the rich body of work investigating language in natural environments. The advent of automated measures of vocalizations and movement have made such in situ research increasingly feasible.

Investigating Children's Interactions in Preschool Classrooms: An Overview of Research Using Automated Sensing Technologies.

New technologies that combine digital sensors with automated processing algorithms are now being deployed to study preschool classrooms. This article provides an overview of these new sensing technologies, focusing on automated speaker classification, the analysis of children's and teachers' speech, and the detection and analysis of their movements over the course of the school day. Findings from recent studies utilizing these technologies are presented to illustrate the contribution of these sensing technologies to our understanding of classroom processes that predict children's language and social development.

Objectively measured teacher and preschooler vocalizations: Phonemic diversity is associated with language abilities.

Over half of US children are enrolled in preschools, where the quantity and quality of language input from teachers are likely to affect children's language development. Leveraging repeated objective measurements, we examined the rate per minute and phonemic diversity of child and teacher speech-related vocalizations in preschool classrooms and their association with children's end-of-year receptive and expressive language abilities measured with the Preschool Language Scales (PLS-5). Phonemic diversity was computed as the number of unique consonants and vowels in a speech-related vocalization.

Empirically Identified Subgroups of Children Served in Part C Early Intervention Programs.

Objective: Early intervention (EI) programs under Part C of the Individuals with Disabilities Education Act serve a developmentally heterogeneous population of infants and toddlers with or at risk of developmental delays or disabilities. The aim of this study was to identify empirically distinct subgroups of children in EI so as to inform early prognosis and service planning.

Methods: We applied mixture modeling to developmental assessment data from 1513 children who enrolled in a large, urban EI program between 2009 and 2013.

Construction and validation of two parent-report scales for the evaluation of early intervention programs.

The State Performance Plan (SPP) developed under the 2004 reauthorization of the Individuals with Disabilities Education Act (IDEA 2004, Public Law 108-446) requires states to collect data and report on the impact of early intervention services on three key outcomes for participating families. The NCSEAM Impact on Family Scale (NIFS) and the NCSEAM Family Centered Services Scale (NFCSS) were developed to provide states with a means to address this new reporting requirement and to collect additional data that would inform program improvement efforts. Items suggested by stakeholder groups were piloted with a nationally representative sample of parents of children with developmental delays or disabilities ages birth to three participating in early intervention services in eight states.

Measuring schools' efforts to partner with parents of children served under IDEA: scaling and standard setting for accountability reporting.

Indicator 8 of the State Performance Plan (SPP), developed under the 2004 reauthorization of the Individuals with Disabilities Education Act (IDEA 2004, Public Law 108-446) requires states to collect data and report findings related to schools' facilitation of parent involvement. The Schools' Efforts to Partner with Parents Scale (SEPPS) was developed to provide states with a means to address this new reporting requirement. Items suggested by stakeholder groups were piloted with a nationally representative sample of 2,634 parents of students with disabilities ages 5-21 in six states.

For which students with learning disabilities are self-concept interventions effective?

We have previously conducted a meta-analysis of outcomes of school-based interventions aimed at enhancing the self-concept of students with learning disabilities (LD). This study extends the previous findings by analyzing intervention effect sizes in relation to students' levels of self-concept prior to intervention. The results of these analyses indicated that only groups of students with documented low self-concept benefited significantly from intervention.
