The overall architecture and major components of a measurement system designed and evaluated to support Response to Intervention (RTI) in the areas of language and literacy in early childhood programs are described. Efficient and reliable measurement is essential for implementing any viable RTI system, and implementing such a system in early childhood programs presents several special challenges. This article describes (a) the general approach taken to developing and evaluating this measurement system, including its conceptual and methodological foundations, methods, and results for developing items and scales for second-generation Individual Growth and Development Indicators (IGDIs 2.0), and (b) use of these scales in a larger decision-making framework for differentiating language and literacy instruction to match the needs of preschool children at risk of academic difficulties. The authors conclude with a review of some challenges associated with developing measurement for differentiated instruction in early childhood settings.
Language skills developed during preschool contribute strongly to later reading and academic achievement. Effective preschool assessment and intervention should focus on core components of language development, specifically oral language skills. The Early Language and Literacy Individual Growth and Development Indicators (IGDIs) are a set of measures that have demonstrated utility in language and early literacy assessment, evaluation, and intervention studies. The purpose of this article is to describe two studies conducted to build on the existing oral language IGDI, Picture Naming, to increase utility for instructional decision making, particularly within an early childhood Response to Intervention framework. Study 1 outlines the initial development and piloting of potential measures and Study 2 describes the revision and continued analysis of the most promising measures. Results of Study 1 and Study 2 indicate that Picture Naming has continued utility as a measure of oral language skill development and that one newly developed oral language IGDI, Definitional Vocabulary, has potential utility.
Learning to read is one of the most important indicators of academic achievement. The development of early literacy skills during the preschool years is associated with improved reading outcomes in later grades. One of these skill areas, phonological awareness, shows particular importance because of its strong link to later reading success. Presented here are two studies that describe the development and revision of four measures of phonological awareness skills: Individual Growth and Development Indicators Sound Blending, Syllable Sameness, Rhyming, and Alliteration 2.0. The authors discuss the measure development process, revision, and utility within an early childhood Response to Intervention framework.
This study evaluated the extent to which existing measures met standards for a continuous suite of general outcome measures (GOMs) assessing children’s early literacy from preschool through early elementary school. The study assessed 316 children from age 3 years (2 years prekindergarten) through Grade 2, with 8 to 10 measures of language, alphabetic principle, phonological awareness, and beginning reading. We evaluated measures at each grade group against six standards for GOMs extracted from earlier work. We found that one measure of oral language met five or six standards at all grade levels, and several measures of phonological awareness and alphabetic principle showed promise across all five grade levels. Results are discussed in relation to ongoing research and development of a flexible and seamless system to assess children’s academic progress across time for effective prevention and remediation, as well as theoretical and empirical analyses in early literacy, early reading, and GOMs.
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.
