Several research studies linking early phonemic awareness to the prevention of later reading difficulties strongly suggest that phoneme segmentation and blending, rather than rhyming and alliteration abilities, are the key aspects of phonemic awareness that are related to the prevention of difficulties. Yet there is a persistent belief among many…

Two studies--one quasi-experimental and one randomized experiment--were designed to evaluate the effectiveness of supplemental instruction in structural analysis and oral reading practice for second- and third-grade students with below-average word reading skills. Individual instruction was provided by trained paraeducators in single- and…

The purpose of this study was to evaluate the effectiveness of code-oriented supplemental instruction for kindergarten students at risk for reading difficulties. Paraeducators were trained to provide 18 weeks of explicit instruction in phonemic skills and the alphabetic code. Students identified by their teachers meeting study eligibility criteria…

This study investigated the effectiveness and efficiency of the Reading Recovery early intervention. At-risk 1st-grade students were randomly assigned to receive the intervention during the 1st or 2nd half of the school year. High-average and low-average students from the same classrooms provided additional comparisons. Thirty-seven teachers from…

Two studies of Grade 1 reading interventions for English-language (EL) learners at risk for reading problems were conducted. Two samples of EL students were randomly assigned to a treatment or untreated comparison group on the basis of their language of instruction for core reading (i.e., Spanish or English). In all, 91 students completed the…

A study evaluated the use of computer-assisted instruction (CAI) to provide training in phonological sensitivity skills to 45 preschool children at-risk for reading problems. Children exposed to CAI made significantly greater gains on rhyming and elision skills compared to controls. Expressive vocabulary scores were predictive of pre- to posttest…
