Efficacy of supplemental phonics-based instruction for low-skilled kindergarteners in the context of language minority status and classroom phonics instruction.

This study tested the efficacy of supplemental phonics instruction for 84 low-skilled language minority (LM) kindergarteners and 64 non-LM kindergarteners at 10 urban public schools. Paraeducators were trained to provide the 18-week (January–May) intervention. Students performing in the bottom half of their classroom language group (LM and non-LM) were randomly assigned either to individual supplemental instruction (treatment) or to classroom instruction only (control). Irrespective of their language status, treatment students (n = 67) significantly outperformed controls (n = 81) at posttest in alphabetics, word reading, spelling, passage reading fluency, and comprehension (average treatment d = 0.83); nevertheless, LM students tended to have lower posttest performance than non-LM students (average LM d = ?0.30) and were significantly less responsive to treatment on word reading. When we examined the contribution of classroom phonics time to student outcomes, we found that the treatment effect on spelling was greater for students in lower phonics classrooms, whereas the treatment effect on comprehension was greater for those in higher phonics classrooms. Finally, when we examined LM students alone, we found that pretest English receptive vocabulary positively predicted most posttests and interacted with treatment only on phonological awareness. In general, pretest vocabulary did not moderate kindergarten LM treatment response. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Code-oriented instruction for kindergarten students at risk for reading difficulties: A randomized field trial with paraeducator implementers.

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 were randomly assigned to 2 groups: individual supplemental instruction and control. Students were pretested in December, midtested, and posttested in May-June of kindergarten. At posttest, treatment students significantly outperformed controls on measures of reading accuracy, reading efficiency, oral reading fluency, and developmental spelling. Treatment students had significantly higher linear growth rates in phonemic awareness and alphabetic knowledge during the kindergarten treatment. At a 1-year follow-up, significant group differences remained in reading accuracy and efficiency. Ethical challenges of longitudinal intervention research are discussed. Findings have policy implications for making supplemental instruction in critical early reading skills available. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Repeated reading intervention: Outcomes and interactions with readers' skills and classroom instruction.

This study examined effects of a repeated reading intervention, Quick Reads, with incidental word-level scaffolding instruction. Second- and third-grade students with passage-reading fluency performance between the 10th and 60th percentiles were randomly assigned to dyads, which were in turn randomly assigned to treatment (paired tutoring, n = 82) or control (no tutoring, n = 80) conditions. Paraeducators tutored dyads for 30 min per day, 4 days per week, for 15 weeks (November-March). At midintervention, most teachers with students in the study were formally observed during their literacy blocks. Multilevel modeling was used to test for direct treatment effects on pretest-posttest gains as well as to test for unique treatment effects after classroom oral text reading time, 2 pretests, and corresponding interactions were accounted for. Model results revealed both direct and unique treatment effects on gains in word reading and fluency. Moreover, complex interactions between group, oral text reading time, and pretests were also detected, suggesting that pretest skills should be taken into account when considering repeated reading instruction for 2nd and 3rd graders with low to average passage-reading fluency.
