The Effects of a Tier 3 Intervention on the Mathematics Performance of Second Grade Students With Severe Mathematics Difficulties.
Abstract The purpose of this study was to determine the effectiveness of a systematic, explicit, intensive Tier 3 (tertiary) intervention on the mathematics performance of students in second grade with severe mathematics difficulties. A multiple-baseline design across groups of participants showed improved mathematics performance on number and operations concepts and procedures, which are the foundation for later mathematics success. In the previous year, 12 participants had experienced two doses (first and second semesters) of a Tier 2 intervention. In second grade, the participants continued to demonstrate low pe...

Structural Validity of the WISC-IV for Students With Learning Disabilities.
Abstract The structural validity of the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) was evaluated using confirmatory factor analysis for a clinical sample of 1,537 students diagnosed with specific learning disabilities (SLD) by school psychologists in two large southwestern school districts. Results indicated that a bifactor model consisting of four first-order domain specific factors and a general intelligence breadth factor fit the data best. Consequently, the structural validity of the WISC-IV for students with SLD was supported by the results of the present study. The general intelligence ...

Building Knowledge Structures by Testing Helps Children With Mathematical Learning Difficulty.
This study investigated whether mathematical performance of fifth grade children with MLD could be improved by developing knowledge structures by testing using a web-based curriculum learning system. A total of 142 children with MLD were recruited; half of the children were in the experimental group (using the system), and the other half were in the control group (not using the system). The children were encouraged to use the web-based learning system at home for at least a 15-min session, at least once a week, for one and a half months. The mean accumulated time of testing on the system for children in the experimental gr...

Predicting Reading Difficulty in First Grade Using Dynamic Assessment of Decoding in Early Kindergarten: A Large-Scale Longitudinal Study.
Abstract The purpose of this study was to examine and compare the classification accuracy of early static prereading measures and early dynamic assessment reading measures administered to 600 kindergarten students. At the beginning of kindergarten, all of the participants were administered two commonly used static prereading measures. The participants were then administered either a dynamic assessment featuring an onset-rime decoding strategy or a dynamic assessment featuring a sound-by-sound strategy. At the end of first grade, those same participants' reading ability was assessed using multiple reading measures. ...

Examining the Efficacy of a Tier 2 Kindergarten Mathematics Intervention.
This study examined the efficacy of a Tier 2 kindergarten mathematics intervention program, ROOTS, focused on developing whole number understanding for students at risk in mathematics. A total of 29 classrooms were randomly assigned to treatment (ROOTS) or control (standard district practices) conditions. Measures of mathematics achievement were collected at pretest and posttest. Treatment and control students did not differ on mathematics assessments at pretest. Gain scores of at-risk intervention students were significantly greater than those of control peers, and the gains of at-risk treatment students were greater than...

Cognitive Profiles of Mathematical Problem Solving Learning Disability for Different Definitions of Disability.
Abstract Three cohorts of third-grade students (N = 813) were evaluated on achievement, cognitive abilities, and behavioral attention according to contrasting research traditions in defining math learning disability (LD) status: low achievement versus extremely low achievement and IQ-achievement discrepant versus strictly low-achieving LD. We use methods from these two traditions to form math problem solving LD groups. To evaluate group differences, we used MANOVA-based profile and canonical analyses to control for relations among the outcomes and regression to control for group definition variables. Results sugges...

The Contributions of Phonological and Morphological Awareness to Literacy Skills in the Adult Basic Education Population.
In this study, phonological decoding was a unique predictor of spelling ability, listening comprehension, and reading comprehension. We also found that morphological awareness was a unique predictor of spelling ability, vocabulary, and listening comprehension. Morphological awareness indirectly contributed to reading comprehension through vocabulary. These findings suggest the need for morphological interventions for this group of learners.

Using Spelling to Screen Bilingual Kindergarteners At Risk for Reading Difficulties.
Abstract For bilingual children, the results of language and literacy screening tools are often hard to interpret. This leads to late referral for specialized assessment or inappropriate interventions. To facilitate the early identification of reading difficulties in English, we developed a method of screening that is theory-driven yet suitable for first-language (L1) and second-language learners of English. We administered five conventional tests (phonological awareness, vocabulary, Wide Range Achievement Test-4 [WRAT-4] spelling, letter identification, rapid naming of digits) to 127 five-year-olds (60 English-L1,...

Oral and Written Expression in Children With Reading Comprehension Difficulties.
Abstract Several studies have highlighted that children with reading comprehension difficulties also have problems in tasks that involve telling a story, in writing or verbally. The main differences identified regard poor comprehenders' lower level of coherence in their productions by comparison with good comprehenders. Only one study has compared poor and good comprehenders' performance in both modalities (oral and written), however, to see whether these modalities differently influence poor comprehenders' performance. We qualitatively and quantitatively compared the performance of good and poor comprehenders in o...

A Meta-Analysis of the Long-Term Effects of Phonemic Awareness, Phonics, Fluency, and Reading Comprehension Interventions.
Abstract 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 posttest and follow-up data (M = 11.17 months) for previously established reading interventions. The posttest effect sizes indicated effects (dw = 0.37) that decreased to follow-up (dw = 0.22). Overall, comprehension and phonemic awareness interventions showed good ma...

Magnitude Representation and Working Memory Updating in Children With Arithmetic and Reading Comprehension Disabilities.
Abstract It has been argued that children with learning disabilities (LD) encounter severe problems in working memory (WM) tasks, especially when they need to update information stored in their WM. It is not clear, however, to what extent this is due to a generally poor updating ability or to a difficulty specific to the domain to be processed. To examine this issue, two groups of children with arithmetic or reading comprehension LD and a group of typically developing children (9 to 10 years old) were assessed using two updating tasks requiring to select the smallest numbers or objects presented. The results showed...

Evaluating the Predictive Impact of an Emergent Literacy Model on Dyslexia in Italian Children: A Four-Year Prospective Cohort Study.
Abstract The strong differences in manifestation, prevalence, and incidence in dyslexia across languages invite studies in specific writing systems. In particular, the question of the role played by emergent literacy in opaque and transparent writing systems remains a fraught one. This research project tested, through a 4-year prospective cohort study, an emergent literacy model for the analysis of the characteristics of future dyslexic children and normally reading peers in Italian, a transparent writing system. A cohort of 450 children was followed from the last year of kindergarten to the third grade in their re...

Number Processing and Heterogeneity of Developmental Dyscalculia: Subtypes With Different Cognitive Profiles and Deficits.
This study investigated if developmental dyscalculia (DD) in children with different profiles of mathematical deficits has the same or different cognitive origins. The defective approximate number system hypothesis and the access deficit hypothesis were tested using two different groups of children with DD (11-13 years old): a group with arithmetic fact dyscalculia (AFD) and a group with general dyscalculia (GD). Several different aspects of number magnitude processing were assessed in these two groups and compared with age-matched typically achieving children. The GD group displayed weaknesses with both symbolic and nonsy...

Pinyin Invented Spelling in Mandarin Chinese-Speaking Children With and Without Reading Difficulties.
This study examined analytical pinyin (a phonological coding system for teaching pronunciation and lexical tones of Chinese characters) skills in 54 Mandarin-speaking fourth graders by using an invented spelling instrument that tapped into syllable awareness, phoneme awareness, lexical tones, and tone sandhi in Chinese. Pinyin invented spelling was significantly correlated with Chinese character recognition and Chinese phonological awareness (i.e., syllable deletion and phoneme deletion). In comparison to good and average readers, poor readers performed significantly worse on the invented spelling task, and a difference wa...

Working Memory in Children With Learning Disabilities in Reading Versus Spelling: Searching for Overlapping and Specific Cognitive Factors.
Abstract In transparent orthographies like German, isolated learning disabilities in either reading or spelling are common and occur as often as a combined reading and spelling disability. However, most issues surrounding the cognitive causes of these isolated or combined literacy difficulties are yet unresolved. Recently, working memory dysfunctions have been demonstrated to be promising in explaining the emergence of literacy difficulties. Thus, we applied a 2 (reading disability: yes vs. no) × 2 (spelling disability: yes vs. no) factorial design to examine distinct and overlapping working memory profiles associ...

Development of Product Relatedness and Distance Effects in Typical Achievers and in Children With Mathematics Learning Disabilities.
Abstract The current study examined the development of two effects that have been found in single-digit multiplication errors: relatedness and distance. Typically achieving (TA) second, fourth, and sixth graders and adults, and sixth and eighth graders with a mathematics learning disability (MLD) performed a verification task. Relatedness was defined by a slow and inaccurate response to false results that were related to one of the operands via a shared multiplication row (e.g., 3 × 4 = 16). Distance was defined by a slow and inaccurate response to false results that were close in magnitude to the true result (e.g...

Syntactic Awareness and Arithmetic Word Problem Solving in Children With and Without Learning Disabilities.
This study examines specifically how syntactic awareness (SA), the ability to manage the grammatical structures of language, affects AWP solving. Three groups of children in elementary education were formed: children with arithmetic learning disabilities (ALD), children with reading learning disabilities (RLD), and children with comorbid arithmetic and reading learning disabilities (ARLD). Mediation analysis confirmed that SA was a mediator variable for both groups of children with reading disabilities when solving AWPs, but not for children in the ALD group. All groups performed below the control group in the problem solv...

Morphological and syntactic awareness in poor comprehenders: another piece of the puzzle.
Abstract Poor comprehenders have intact word-reading skills but struggle specifically with understanding what they read. We investigated whether two metalinguistic skills, morphological and syntactic awareness, are specifically related to poor reading comprehension by including separate and combined measures of each. We identified poor comprehenders (n = 15) and average comprehenders (n = 15) in Grade 4 who were matched on word-reading accuracy and speed, vocabulary, nonverbal cognitive ability, and age. The two groups performed comparably on a morphological awareness task that involved both morphological and synta...

The Effect of Tutoring With Nonstandard Equations for Students With Mathematics Difficulty.
Abstract Students often misinterpret the equal sign (=) as operational instead of relational. Research indicates misinterpretation of the equal sign occurs because students receive relatively little exposure to equations that promote relational understanding of the equal sign.

At the Intersection of Math and Reading Disabilities: Introduction to the Special Issue.
Abstract Individuals with comorbid disabilities in mathematics and reading face significant challenges in acquiring the componential skills related to each domain. Persons with these comorbid conditions are significantly understudied and this paucity of work limits how effective practitioners can be at addressing the needs of this population. In the United States, roughly 7% of all children suffer from math disability; of these, an estimated 17% to 66% also has a comorbid reading disability. Underspecification of current conceptualizations of math and reading disabilities, including how to best identify and classif...

A Meta-Analysis of Interventions for Struggling Readers in Grades 4-12: 1980-2011.
Abstract 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 interventions studied over the past 30 years, (b) how the magnitude of the effect varies based on student, intervention, and research design characteristics, and (c) what differences in effectiveness exist between more recent interventions and older ones. The analys...

Sight Word and Phonics Training in Children With Dyslexia.
Abstract The aims of this study were to (a) compare sight word training and phonics training in children with dyslexia, and (b) determine if different orders of sight word and phonics training have different effects on the reading skills of children with dyslexia. One group of children (n = 36) did 8 weeks of phonics training (reading via grapheme-phoneme correspondence rules) and then 8 weeks of sight word training (reading irregular words as a whole), one group did the reverse (n = 36), and one group did phonics and sight word training simultaneously for two 8-week periods (n = 32). We measured the effects of pho...

Academic Achievement Among Juvenile Detainees.
Abstract The literature has long pointed to heightened frequencies of learning disabilities (LD) within the population of law offenders; however, a systematic appraisal of these observations, careful estimation of these frequencies, and investigation of their correlates and causes have been lacking. Here we present data collected from all youth (1,337 unique admissions, mean age 14.81, 20.3% females) placed in detention in Connecticut (January 1, 2010-July 1, 2011). All youth completed a computerized educational screener designed to test a range of performance in reading (word and text levels) and mathematics. A su...

Cognitive Strategies, Working Memory, and Growth in Word Problem Solving in Children With Math Difficulties.
This study investigated the role of strategy instruction and working memory capacity (WMC) on word problem solving accuracy in children with (n = 100) and without (n = 92) math difficulties (MD). Within classrooms, children in Grades 2 and 3 were randomly assigned to one of four treatment conditions: verbal-only strategies (e.g., underlining question sentence), verbal + visual strategies, visual-only strategies (e.g., correctly placing numbers in diagrams), or untreated control. Strategy interventions included 20 sessions in both Year 1 and Year 2. The intent-to-treat as well as the "as-treated" analyses showed that treatm...

Underlying Reading-Related Skills and Abilities Among Adult Learners.
Abstract This exploratory study identified underlying skill and ability differences among subgroups of adolescent and young adult struggling readers (N = 290) overall and in relation to a fluency-based instructional grouping method. We used principal axis factoring of participants' scores on 18 measures of reading-related skills and abilities identified in the research literature to identify a smaller set of generally uncorrelated constructs. The four underlying factors of the 18 measures explained 62.7% of the variance. We labeled these factors Encode/Decode (44.5%), Vocabulary (9.5%), Processing Speed (5.2%), and...
