title: Modeling the response of normally achieving and at-risk first grade children to word reading instruction.
abstract: The purpose of this study was to identify important subject characteristics that predicted individual differences in responsiveness to word reading instruction in normally achieving and at-risk first grade children. This was accomplished by modeling individual word and nonword reading growth, and the correlates of change in these skills, in first grade students during two different phases of the school year. In the first phase of the study (October-January), word and nonword reading skill was modeled in normally achieving and at-risk children. Results of growth modeling indicated significant group differences in word and nonword reading growth parameters. A combination of phonemic awareness skill, advanced graphophoneme knowledge, and initial word/nonword reading skill predicted word and nonword reading growth in the control group, whereas, a combination of rapid naming speed, letter sound knowledge, and phonemic awareness skill predicted word and nonword reading growth in the at-risk group. In the second phase of the study (January-April), a subgroup of the at-risk subjects who exhibited limited growth in word reading skills during the first phase of the study was enrolled in 12 weeks of small group reading intervention designed to improve reading skills. Results of growth modeling indicated significant increases in word and nonword reading growth rates in this group during the intervention phase. Only rapid naming speed uniquely predicted word and nonword reading growth in the group of subjects receiving intervention.
