Effectiveness of Individualized Instruction for Kindergarten Children with a Developmental Lag

Abstract
A curriculum emphasizing instruction in areas of greatest deficit was provided to children demonstrating a developmental lag. Of 135 children so classified, 90 were placed in an experimental program and 45 participated as a control group in a regular kindergarten program. A second control group consisted of 45 randomly selected developmentally normal subjects also in a regular kindergarten program. Mean score differences between groups and sexes for general development, visual perception, language, and general readiness were obtained. Analysis of covariance showed no significant differences by treatment or sex on any of the criterion measures.
