Great strides have been made in the development of effective methods of instruction for children with dyslexia. However, individual response to treatment varies, and weaknesses persist for some students with dyslexia despite otherwise effective instruction. Continued efforts are needed to support the prospective identification of poor response,…

Purpose: The purpose of this study was to determine the extent to which school-age children with speech sound disorder (SSD) exhibit concomitant reading difficulties and examine the extent to which phonological processing and speech production abilities are associated with increased likelihood of reading risks. Method: Data were obtained from 120…

This is the second of three reports from MDRC's evaluation of the Success for All (SFA) scale-up demonstration, funded under the U.S. Department of Education's Investing in Innovation (i3) competition. The report presents updated findings on SFA's implementation and impacts in the scale-up sites participating in the evaluation. The i3 evaluation…

The development of reading skills from age seven until age 19 was investigated for children who were referred for special education preschool intervention using latent growth curve analysis (n=206). Approximately one-third of the study sample did not require special education services after preschool, providing a natural comparison group. Reading…

Practitioners are increasingly expected to provide reading instruction to students with intellectual disabilities to help them become literate. Whereas explicit, systematic reading instruction is effective at preventing reading difficulties for most young children, its effectiveness for children with intellectual disabilities remains unclear. The…

In Study 1 we evaluated whether each of three kinds of reading fluency (oral, silent-sentences, silent-passages) contributed uniquely to reading comprehension when children were in second grade (when oral reading is emphasized) and again when they were in fourth grade (when silent reading is emphasized). In Study 2 we evaluated the relationship of…

Latino English Language Learners represent the largest group of language minority students attending public school in the United States. Research is needed to address the early literacy problems which impede this population from acquiring literacy in the English language with efficacy and to determine the most effective assessment and intervention…

This study is the first randomized study of the impacts of the vocabulary instruction program Kindergarten PAVEd for Success (K-PAVE) (Hamilton and Schwanenflugel 2011) on low-income students in kindergarten and grade 1. The study has two components. The first component is a test of the impacts of one year of the K-PAVE vocabulary instruction in…

This study examined the relationships between the cognitive processes of rapid naming and phonological processing and various literacy skills. Variables measured and used in this analysis were phonological processing, rapid naming, reading comprehension, isolated and nonsense word reading, and spelling. Data were collected from 65 second-to-fifth…

Using an extant database, we examined three grade 1 criteria for identifying response to intervention (RTI) in English language learners (ELLs): (a) set benchmark criteria with a standard score above 95 (37th %ile) on both decoding and comprehension measures and a raw score of 40 or more correct words per minute (CWPM) on oral reading fluency; (b)…
