Sixteen preschool children with speech and/ or language disorders received phonological awareness training for a period of 9 months. Eight children attended a preschool classroom, and 8 children attended a pre-kindergarten classroom. The classrooms were located in a private school for children with speech and language disorders. A group of older children with speech and/or language disorders served as a nontreatment comparison group. Children in the treatment groups received 15 minutes of small-group lessons twice each week for two semesters. Classroom-based treatment focused on rhyming the first semester and on phoneme awareness the second semester.Rhyming and phoneme awareness activities were adapted from the literature on the development of phonological awareness in typicallyachieving children. Results revealed that preschool children with speech and/or language disorders made significant improvement in rhyming and phoneme awareness. Comparisons with the non-treatment group indicated that gains in phoneme awareness were likely a result of the treatment rather than maturation or other aspects of the curriculum. We recommend the inclusion of some form of phonological awareness training, particularly phoneme awareness training, in intervention programs for preschoolers.T he relationship between phonological awareness and early reading achievement has been clearly established. Research has shown that the two skills are highly correlated in beginning readers, that the phonological awareness skills of prereaders predict early reading abilities, that training in phonological awareness results in improved reading achievement, and that children who are poor readers and illiterate adults have less well developed phonological awareness abilities than good readers (see, for example, reviews by Adams, 1990;Blachman, 1994;and Wagner & Torgesen, 1987). These results hold in spite of the numerous ways in which both phonological awareness and reading abilities have been measured and in spite of variation in how phonological awareness has been trained. In short, these findings have been compelling and robust. Clearly, phonological awareness in prereaders is a powerful predictor of subsequent early reading achievement. Explicit training in phonological awareness has a positive impact on reading and spelling skills, and phonological awareness can be effectively trained in prereaders with a subsequent positive impact on reading ability (Blachman, 1994;Lundberg, Frost, & Petersen, 1988).The purpose of this study was to determine whether phonological awareness (including rhyming and phoneme awareness) could be effectively trained in preschool children with speech and/or language disorders in a classroom setting. The critical aspects of this treatment study that depart from previous research include (a) that the children had speech and/or language disorders, (b) that they were preschool-aged, (c) that the training took place in a classroom context, and (d) that the training included a rhyming phase and a phoneme awareness phase.
