Response to intervention (RTI) is a method for providing academic support to students and for identifying specific learning disabilities (SLDs). Using interrupted time series and hazard models, we examined if statewide RTI adoption in the U.S. state of Tennessee was associated with changes in rates of SLD and first-time SLD identification in…

Word problem-solving (WPS) poses a significant challenge for many students, particularly those with mathematics difficulties (MD), hindering their overall mathematical development. To improve WPS proficiency, providing individualized and intensive interventions is critical. This umbrella review examined 11 medium- to high-quality meta-analyses to…

We examined the efficacy of a Technology-Based Early Language Comprehension Intervention (TeLCI) designed to teach inferencing in a non-reading context. A group of Grades 1 and 2 students from 2 elementary schools in the U.S. Midwest identified as at risk of comprehension difficulties were assigned randomly to a business-as-usual control group or…

For students who show inadequate response to research-based intervention, intensification of intervention using data-based decision making (DBDM) is recommended. There is a paucity of research on upper elementary students related to the efficacy of (a) word reading interventions and (b) DBDM procedures. This randomized controlled trial examined…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

According to a language-integrated view of spelling development, learning to spell involves the same language-learning skills across alphabetic systems. A prediction based on this view is that the same spelling training should be equally effective for learning to spell in a shallow (Italian, native language) or an opaque (English, additional…

Many students at risk for or identified with reading disabilities need intensive reading interventions. This meta-analysis provides an update to the Wanzek and Vaughn synthesis on intensive early reading interventions. Effects from 25 reading intervention studies are analyzed to examine the overall effect of intensive early reading interventions…

Despite the emerging evidence base on response to intervention, there is limited research regarding how to effectively use progress-monitoring data to adjust instruction for students in Tier 2 intervention. In this study, we analyzed extant data from a series of randomized experimental studies of a kindergarten supplemental reading intervention to…

As empirical studies have consistently shown, low achievement in mathematics at the secondary level can often be traced to deficits in the understanding of certain basic arithmetic concepts taught in primary school. The present intervention study in middle schools evaluated whether such learning deficits can be reduced effectively and whether the…

Much is known about short-term--but very little about the long-term--effects of reading interventions. To rectify this, a detailed analysis of follow-up effects as a function of intervention, sample, and methodological variables was conducted. A total of 71 intervention-control groups were selected (N = 8,161 at posttest) from studies reporting…

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…

This response to Bashir and Scavuzzo (EC 602 669) suggests that their view that dyslexia is a chronic, pervasive condition is too limiting. An alternative view of dyslexia as an acute, interactive condition is proposed, and related implications for instructional curricula and reading achievement are offered. (Author/ DB)

This article summarizes the findings of research studies designed to improve the comprehension of expository text for students with learning disabilities. Twenty-nine studies were located that met the inclusion criteria. Interventions gleaned from the review were categorized as content enhancement (i.e., advance and graphic organizers, visual…

Several multiple-probe-across-participants design studies were employed to evaluate the effectiveness of a supplemental tutoring intervention using "Read Well" (Sprick, Howard, and Fidanque, 1998-2000). In Year 1, we conducted two studies with 7 first-, second-, and third grade children (1 girl and 6 boys), who were classified as having…

The article examines the following issues: (1) overlapping symptoms of chemical impairment and learning handicap that may result in misdiagnosis; (2) student populations at high risk for chemical abuse; (3) preventive measures; and (4) intervention and treatment for chemically impaired students. A table of drug symptoms and a behavioral checklist…
