This article reflects a metaview of the work of the three research projects funded through the Institute for Education Sciences under the Reading for Understanding competition that addressed middle-grade through high school readers (grades 4-12). All three projects shared the assumption that instruction is necessary for successful reading to learn…

A subset of students fail to respond adequately to reading interventions. This synthesis systematically reviews studies in which students in grades K-3 responded inadequately to a Tier 2 reading intervention and were provided with a Tier 3 intervention. Descriptions of the Tier 3 reading interventions and effects are provided. To meet inclusion…

This meta-analysis synthesizes the last two decades of experimental and quasi-experimental research on reading instruction across academic contexts (e.g., social studies, science, mathematics, English language arts) for English learners (ELs) in grades 4 through 8, to determine (a) the overall effectiveness of reading instruction for upper…

This meta-analysis synthesizes the literature on interventions for struggling readers in Grades 4 through 12 published between 1980 and 2011. It updates Scammacca et al.'s analysis of studies published between 1980 and 2004. The combined corpus of 82 study-wise effect sizes was meta-analyzed to determine (a) the overall effectiveness of reading…

The authors conducted a synthesis of studies of reading comprehension interventions for middle school students (Grades 6-8) identified with a learning disability. They identified 12 studies between 1979 and 2009 with treatment and comparison designs and 2 single-participant studies. Findings from the studies indicate large effect sizes for…

The authors examined the methodologies of articles in teaching-and-learning research journals, published in 1994 and in 2004, and classified them as either intervention (based on researcher-manipulated variables) or nonintervention. Consistent with the findings of Hsieh et al., intervention research articles declined from 45% in 1994 to 33% in…

Conducts a meta-analysis of supplemental, adult-instructed one-to-one reading interventions for elementary students (N=1,539) at risk for reading failure. Results indicate that interventions using trained volunteers or college students were highly effective. Studies comparing one-to-one with small-group supplemental instruction showed no advantage…

A meta-analysis of 20 studies (1975-1995) indicated positive effects for alternative grouping formats for teaching reading to students with disabilities compared to whole-class instruction, particularly for student pairing. In addition, analyses indicated that outcomes for students involved in cross-age tutoring varied significantly by students'…
