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.

At-risk 1st graders were randomly assigned to tutoring in more or less decodable texts, and instruction in the same phonics program. The more decodable group (n = 39) read storybooks that were consistent with the phonics program. The less decodable group (n = 40) read storybooks written without phonetic control. During the first 30 lessons, storybook decodability was 85% versus 11% for the 2 groups. Tutoring occurred 4 days per week for 25 weeks. A control group did not receive tutoring in phonics or story reading. Both tutored groups significantly surpassed the control on an array of decoding, word reading, passage reading, and comprehension measures. However, the more and less decodable text groups did not differ on any posttest.

In this quasi-experimental study, which is part of a series of investigations on supplemental reading tutoring variations, the relative effectiveness of more intense decoding instruction or text reading practice was examined. Fifty-seven first-grade students scoring in the lowest quartile for reading skills received either classroom reading instruction or one of two treatments: tutoring in word study with text reading practice, or word study tutoring alone. Individual instruction was provided by trained paraprofessional tutors. At the end of first grade, treatment students significantly outperformed their nontutored peers on measures of reading accuracy, reading comprehension, reading efficiency, passage reading fluency, and spelling. Differential treatment effects on passage reading fluency are examined, taking into consideration pretest skill levels and text reading practice characteristics.

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 multiletter phoneme—grapheme correspondences; structural analysis of inflected, affixed, and multi-syllable words; exception word reading; and scaffolded oral reading practice. Both studies revealed short-term word level and fluency effects.

In this article we report data from a longitudinal study of one–to–one tutoring for students at risk for reading disabilities. Participants were at–risk students who received phonics–based tutoring in first grade, students who were tutored in comprehension skills in second grade, and students tutored in both grades 1 and 2. At second–grade posttest, there were significant differences in word identification and word attack between students who were tutored in first grade only compared to students who were also tutored in second grade, favoring students who were tutored in first grade only. Overall, there were no advantages to a second year of tutoring. For students tutored in second grade only, there were no differences at second–grade posttest compared to controls. Schools may have selected students who did not respond to first–grade tutoring for continued tutoring in second grade. Findings are discussed in light of decisions schools make when using tutors to supplement reading instruction for students with reading difficulties.

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.

A total of 46 children in Grades 2 and 3 with low word-level skills were randomly assigned to 1 of 2 groups that received supplemental phonics-based reading instruction. One group received intervention October through March (21.5 hours), and one group served as a control from October through March and later received intervention March through May (17.5 hours). Paraeducators trained in a standard treatment protocol provided individual instruction for 30 min per day, 4 days per week. At the March posttest, the early treatment (ET; n = 23) group outperformed the controls (late treatment, LT; n = 20) on reading accuracy and passage fluency. Across both groups, second graders outperformed third graders on these same measures. At the 3-month follow-up, the ET group showed no evidence of decline in reading accuracy, passage fluency, or words spelled; however, 3rd-grade ET students had significantly higher spelling skills compared to 2nd graders. The LT group demonstrated significant growth during their intervention in reading accuracy and spelling, but not passage fluency. When we compared the ET and LT groups on their gains per instructional hour, we found that the ET group made significantly greater gains than the LT group across all 3 measures. The results support the value of paraeducator-supplemented reading instruction for students below grade level in word identification and reading fluency.

This study examined the long-term growth of reading skills following 1 year of supplemental 1st-grade code-oriented intervention provided by paraeducators. A group of 79 1st graders with reading skills averaging in the lowest quartile received explicit alphabetic and decoding instruction and were assessed postintervention and at 1-year intervals through the end of 3rd grade. Growth model results indicate that students continued to benefit from 1st-grade intervention through the end of 3rd grade, with average performance near 50th percentile on decoding and reading fluency, near 40th percentile on word reading and comprehension, and near 30th percentile on spelling. Without exception, both receptive language and rapid automatized naming uniquely predicted 3rd-grade outcomes. Of the students remaining in study in fall of 2nd grade, a subgroup selected by their teachers received additional supplemental instruction. Students referred for added intervention continued to perform significantly lower than those more readily remediated with 1st-grade intervention alone.

Many students have difficulty achieving reading fluency, and nearly half of fourth graders are not fluent readers in grade-level texts. Intensive and focused reading practice is recommended to help close the gap between students with poor fluency and their average reading peers. In this study, the Quick Reads fluency program was used as a supplemental fluency intervention for fourth and fifth graders with below-grade-level reading skills. Quick Reads prescribes a repeated reading procedure with short nonfiction texts written on grade-appropriate science and social science topics. Text characteristics are designed to promote word recognition skills. Students were randomly assigned to Quick Reads instruction that was implemented by trained paraeducator tutors with pairs of students for 30 minutes per day, 4 days per week, for 18 weeks. At posttest, Quick Reads students significantly outperformed classroom controls in vocabulary, word comprehension, and passage comprehension. Fluency rates for both treatment and control groups remained below grade level at posttest.

This study replicates research on the efficacy of a repeated reading intervention with word-level instruction for students in Grades 2 and 3 with low to moderate fluency skills, examines differences between treatment implementers, and tests unique contributions of treatment-related variables on outcomes. Students from 13 schools were randomly assigned to dyads; dyads were randomly assigned to treatment or control conditions. Schools were matched into treatment implementer groups (teachers or paraeducators) at study onset. Tutoring occurred during school hours for 15 weeks (M = 25.5 hr). Multilevel model results showed treatment students (n = 98) gained more than controls (n = 104) on measures of letter-sound knowledge (d = .41), fluency (d = .37–.38), and comprehension (d = .30–.31); students tutored by teachers gained more than their paraeducator-tutored peers on word reading and fluency. Finally, dyads tutored with greater fidelity gained more in word reading and fluency; dyads that read more complex words in their texts gained less on letter-sounds, fluency, and comprehension.
