Topics in Early Childhood Special Education

Children who are dual language learners (DLLs) often have more difficulty acquiring English early literacy skills than their English monolingual peers. Much remains to be learned about efficacious early literacy instructional interventions and their effects on English early literacy skills of DLLs. The purposes of this systematic review were to describe key features of English early literacy interventions provided to children who were DLLs and their effects on English early literacy skills. We conducted an electronic database search and used additional methods to identify 25 studies. Studies varied in defining and characterizing children who were DLLs, including whether they were simultaneous versus sequential DLLs and how information was gathered about primary and secondary language exposure. Use of bilingual and monolingual instruction showed promise for enhancing English early literacy skills, although mixed findings were common when both language and code-related outcomes were measured. Implications for future research and practice are discussed.

For young Spanish–English dual language learners (SE-DLLs), early literacy skills, including phonological awareness and alphabet knowledge in Spanish as well as English, are crucial to their reading success. However, there is a lack of research about how SE-DLLs develop early literacy skills, and how their rates of performance can inform evidence-based intervention. This article examined to what degree SE-DLLs with disabilities or at risk for later reading difficulties on early literacy skills demonstrated growth on English and Spanish measures of early literacy when compared with their typically developing peers. Hierarchical linear modeling was used to analyze growth for 325 SE-DLLs on four Individual Growth and Development Indicators that assessed phonological awareness and alphabet knowledge in English and Spanish. Results indicated that at-risk and typically developing children showed significant slopes for all measures and that at-risk children grew faster than typically developing children on Spanish alphabet knowledge measures.

The social validity of intervention research has been emphasized in special education and related fields for decades. There is relatively little focus on social validity that considers culturally and linguistically diverse populations. Eleven articles met the inclusionary criteria for this systematic review and were evaluated to describe social validity in early language intervention research—specifically with young (birth through 5 years) dual language learners (DLLs). We examined how social validity was considered and addressed, how social validity was measured, and the results of social validity assessments. Definitions of social validity were generally vague, and researchers in most studies only considered social validity post intervention rather than prior to starting or during the interventions. Participants generally viewed interventions positively, but incomplete data were often reported.

Evidence-based treatments for young children with developmental language delays include caregiver-implemented naturalistic interventions. However, there is little research on culturally appropriate interventions for Spanish-speaking caregivers from low–socioeconomic status (SES) households and their young children with identified language delays. We compared interaction strategies of Latino Spanish-speaking caregivers from low-SES backgrounds and non-Latino English-speaking caregivers from high-SES backgrounds with their children with language delays. Caregivers’ interactions were coded for (a) interaction characteristics, (b) use of naturalistic language support strategies, and (c) linguistic input. Results indicated Spanish-speaking Latino caregivers from low-SES backgrounds used a more directive, responsive, and warm interaction style than non-Latino caregivers. Non-Latino, English-speaking caregivers from high-SES backgrounds used more cognitively stimulating strategies, spent more time observing and narrating play, and used longer utterances and more lexical diversity. Findings provide directions for future research and guidance for clinicians working with Latino families from low-SES households.
