دانلود کتاب The Receptive-Expressive Emergent Language Scale (REELS) For Measurement Of Language Skills In Infancy

The REEL-3 is a valuable assessment and planning instrument for Early Childhood Intervention programs mandated under PL 99-457. It has two core subtests for Receptive and Expressive Language, and a new supplementary subtest, Inventory of Vocabulary Words. Results are obtained from a caregiver interview.

The REEL-3 is based on a contemporary linguistic model. It includes current studies relating to normative base, reliability and validity. The normative sample includes 1,112 infants and toddlers from around the United States. The demographic characteristics of the sample were matched to the 2000 census. The normative sample was stratified on the basis of age, gender, race, ethnic group membership and geographic location. Standard scores, percentile ranks and age equivalents are provided.

The average reliability coefficients for all test scores are high (exceeding .90). Test/retest studies show that REELS is stable over time.
