Narration, or storytelling, is an important aspect of language. Narrative skills have academic and social importance. This study evaluated the effects of a narrative intervention on story retelling and personal story generation skills of preschoolers with risk factors and narrative language delays. Narrative intervention was delivered in a small group arrangement, and materials, activities, and assistance were systematically adjusted within sessions to facilitate increasingly independent practice of oral narration. Participants were 5 preschoolers enrolled in a Head Start classroom who performed below average on two narrative language tasks. Participants made substantial gains in narrative retelling, demonstrated improved preintervention to postintervention scores for personal story generations, and maintained improvements when assessed following a 2-week break. These results have several implications for practice, including narrative intervention's versatility with a range of children from diverse backgrounds and its use of economic and efficient classroom-based small group formats for intervention.
Evidence-based practice (EBP) is a model of professional decision-making in which practitioners integrate the best available evidence with client values/context and clinical expertise in order to provide services for their clients. This framework provides behavior analysts with a structure for pervasive use of the best available evidence in the complex settings in which they work. This structure recognizes the need for clear and explicit understanding of the strength of evidence supporting intervention options, the important contextual factors including client values that contribute to decision making, and the key role of clinical expertise in the conceptualization, intervention, and evaluation of cases. Opening the discussion of EBP in this journal, Smith (The Behavior Analyst, 36, 7-33, 2013) raised several key issues related to EBP and applied behavior analysis (ABA). The purpose of this paper is to respond to Smith's arguments and extend the discussion of the relevant issues. Although we support many of Smith's (The Behavior Analyst, 36, 7-33, 2013) points, we contend that Smith's definition of EBP is significantly narrower than definitions that are used in professions with long histories of EBP and that this narrowness conflicts with the principles that drive applied behavior analytic practice. We offer a definition and framework for EBP that aligns with the foundations of ABA and is consistent with well-established definitions of EBP in medicine, psychology, and other professions. In addition to supporting the systematic use of research evidence in behavior analytic decision making, this definition can promote clear communication about treatment decisions across disciplines and with important outside institutions such as insurance companies and granting agencies.
The construct of phonological awareness was explored by examining the effects of instructional treatments on the development of specific and generalized phonological skills for kindergarten children. Sixty-six children with low phonological manipulation skills were randomly assigned to 1 of 2 treatments or a control condition: (a) auditory blending and segmenting with limited letter-sound correspondences; (b) a global array of phonological tasks, with letter-sound correspondences; or (c) only letter-sound instruction. Children in both treatments showed improved phonological abilities, which transferred to a reading analog task. Treated children achieved a level of phonological awareness comparable to that of higher skilled children. The combination of blending and segmenting instruction encouraged generalized phonological awareness; however, the ability to blend and segment accounted for more variance in reading analog scores than did other phonological tasks.
This study examined the feasibility of teaching phonological manipulation skills to preschool children with disabilities. Forty-seven children, 4-6 years old, enrolled in a special education preschool, were randomly assigned to receive training in one of three categories of phonological tasks (rhyming, blending, and segmenting) or a control group. Results indicated that children were able to make significant progress in each experimental category, but that they demonstrated little or no generalization either within a category (e.g., from one type of blending task to another type of blending task) or between categories (e.g., from blending to segmenting). Although the children's level of cognitive development significantly predicted some learning outcomes, it did not appear to limit the learning of phonological tasks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
