This article reports the results from a randomized control field trial that investigated the impact of an enhanced decoding and spelling curriculum on the development of adult basic education (ABE) learners' reading skills. Sixteen ABE programs that offered class-based instruction to Low-Intermediate-level learners were randomly assigned to either…

This experimental study was designed to validate a short-term supplemental reading intervention for at-risk first-grade children. Although substantial research on long-term supplemental reading interventions exists, less is known about short-term interventions. Thirty first-grade children were randomly assigned to intervention or control…

To compare the efficacy of instructional programs for adult learners with basic reading skills below the 7th-grade level, 300 adults were randomly assigned to 1 of 3 supplementary tutoring programs designed to strengthen decoding and fluency skills, and gains were examined for the 148 adult students who completed the program. The 3 intervention…

This study reports findings on the relative effects from a yearlong secondary intervention contrasting large-group, small-group, and school-provided interventions emphasizing word study, vocabulary development, fluency, and comprehension with seventh- and eighth-graders with reading difficulties. Findings indicate that few statistically…

Portland Public Schools (PPS), the largest school district in Oregon, serves more than 46,000 students in regular and special programs. More than 2,900 classroom teachers address the needs of a diverse student population (44% minority, 46% low income, 14% special education, 9% English language learners). A district needs assessment in fall 2005…

The Illinois Striving Readers (ISR) Project had two purposes: (1) implement a supplemental reading intervention for students in ninth grade who were reading below grade level; and (2) study the impact of the intervention on students' performance on standardized assessments using a randomized control trial design. The Illinois Striving Readers…

The purpose of this study was to evaluate the efficacy of a classroom-teacher-delivered reading intervention for struggling readers called the Targeted Reading Intervention (TRI), designed particularly for kindergarten and first-grade teachers and their struggling students in rural, low-wealth communities. The TRI was delivered via an innovative…

This study examined the effectiveness of a yearlong, researcher-provided, Tier 2 (secondary) intervention with a group of sixth-graders. The intervention emphasized word recognition, vocabulary, fluency, and comprehension. Participants scored below a proficiency level on their state accountability test and were compared to a similar group of…

This study compared the effects of 2 supplemental interventions on the beginning reading performance of kindergarteners identified as at risk of reading difficulty. Students (N = 206) were assigned randomly at the classroom level either to an explicit/systematic commercial program or to a school-designed practice intervention taught 30 min per day…

The relative effectiveness of two computer-assisted instructional programs designed to provide instruction and practice in foundational reading skills was examined. First-grade students at risk for reading disabilities received approximately 80 h of small-group instruction in four 50-min sessions per week from October through May. Approximately…

This longitudinal study investigated 196 Hispanic English learners' responses to an English instructional intervention from kindergarten to second grade. The effect of student gender was also examined as a secondary focus. The intervention consisted of ongoing professional development and structured and systematic English intervention during an…

This intervention study tested whether invented spelling plays a causal role in learning to read. Three groups of kindergarten children (mean age = 5 years 7 months) participated in a 4-week intervention. Children in the invented-spelling group spelled words as best they could and received developmentally appropriate feedback. Children in the 2…

Unfortunately, little is known about school-based interventions that address the needs of struggling adolescent readers. To help fill these gaps in knowledge and to provide evidence-based guidance to practitioners, the U.S. Department of Education initiated the Enhanced Reading Opportunities (ERO) Study--a demonstration and random assignment…

The effectiveness study examined a supplemental reading intervention that may be appropriate as one component of a response-to-intervention (RTI) system. First-grade students in 31 schools who were at risk for reading difficulties were randomly assigned to receive Responsive Reading Instruction (RRI; Denton, 2001; Denton & Hocker, 2006; n =…

This paper reports the fifth-year results of a study comparing the English and Spanish language and reading performance of Spanish-dominant children randomly assigned beginning in kindergarten to Transitional Bilingual Education (TBE) or Structured English Immersion (SEI). This is the first randomized study to compare TBE and SEI reading…
