Topics in Early Childhood Special Education

Research in early intervention/early childhood special education (EI/ECSE) is focused on identifying effective practices related to positive outcomes for young children with disabilities and their families. Individual responses to evidence-based practices are often variable, and non-responders are common. Single case research (SCR) might be particularly well suited to examining differences across participants given the dynamic nature of the methodology. The repeated measurement of behaviors and visual analysis of subsequent data allow researchers to continually monitor behavior and make necessary adaptations to ensure positive child outcomes. The purpose of this article is to illustrate the dynamic nature of single case research design (SCRD) and the utility of SCRD in the iterative development of adaptive evidence-based practices using three examples of SCR studies. Implications for research and practice in EI/ECSE are discussed.

This study examined the effects of a multi-component intervention program (i.e., extended instruction and iPad app technology) on preschool children’s vocabulary. Instruction utilizing the intervention program was provided across 6 storybooks, 4 verbs per book, for a total of 24 verbs. Dependent variables included expressive vocabulary, definitions/examples, and generalization. A repeated acquisition (RA) design was used across six participants. There were increases across all participants from pretest to posttest for the expressive vocabulary and definition/examples measures. In addition, participants were able to generalize knowledge to novel images, both expressively and receptively. Implications for research and practice are provided.

The aim of the current pilot study was to evaluate the implementation of a routines-based early childhood intervention (RBECI) model by Australian Early Childhood Intervention (ECI) professionals. The RBECI model consisted of four key components: (a) Routines-Based Interviews (RBIs), (b) participation-based goals, (c) home visits, and (d) community consultations. Five ECI professionals and nine families were recruited from an Australian ECI service. Professionals’ ability to implement the model was assessed immediately before and 6 months after receiving training in the model. Individual in-depth interviews elicited professionals’ perspectives on implementing the model. Results revealed that professionals’ knowledge, understanding, confidence, and home visiting skills increased from pre- to post-intervention, but community consultation skills did not. There were limitations in the quality of RBIs and participation-based goals produced. Overall, professionals were positive about the implementation of the model. The findings provide support for the adoption of the RBECI model in ECI more broadly.

This study used a multiple probe across participants’ research design to evaluate the effects of instruction on the acquisition of letter-sound correspondences (LSCs) by three young children with autism spectrum disorder and limited speech. All three children (ages 3–5 years) reached criterion for identifying the LSCs targeted during instruction, and a Nonoverlap of All Pairs (NAP) analysis showed evidence of medium to strong treatment effects. All three children also provided evidence of maintenance and generalization of LSC skills to other tasks. Implications for instruction and future research directions are discussed.

The Individuals With Disabilities Education Act mandates that very young children with disabilities be served through Part C services. Families of young children with disabilities who are also living in poverty are often the primary recipients of these services. To better understand the experiences of families, particularly those living in poverty, within the early intervention (EI) system, we reviewed four EI components: (a) family-centered orientation, (b) natural learning environments, (c) collaborative team processes, and (d) service integration. We discuss the implications of these components for the preparation and training of EI providers to work with families, including those living in poverty.
