Predicting Risk for Comorbid Reading and Mathematics Disability Using Fluency-Based Screening Assessments
Martin BN and Fuchs LS
The first purpose of this study was to examine the prevalence of risk for comorbid reading and mathematics disabilities (RMD) at start of first grade, when measured in a representative sample of 3,062 students with first-grade fluency measures (word reading; computation). The second purpose was to examine the utility of these measures for predicting RMD status within a sample of 577 students when RMD status was assessed at the end of second grade in terms of reading and math accuracy. When set at or below the 16 percentile, first-grade risk for RMD was two times more common than chance; at or below the 7 percentile, it was five times more common. Logistic regression showed that the two first-grade fluency measures accurately distinguished students with and without RMD in second grade; however, when cut scores were set to capture 85% of students with RMD, false positives were high. Overall, the results provide support for the use of fluency measures as an initial gating procedure in first grade, but additional gating steps appear necessary in the screening process to reduce false positives.

The Effects of One versus Two Years of Intensive Reading Intervention Implemented with Late Elementary Struggling Readers
Miciak J, Roberts G, Pat Taylor W, Solis M, Ahmed Y, Vaughn S and Fletcher JM
We examined the effectiveness of a researcher-provided reading intervention with 484 fourth graders with significant reading difficulties. Students were randomly assigned to one year of intervention, two years of intervention, or a business-as-usual comparison condition (BAU). Students assigned to two years of intervention demonstrated significantly greater gains in reading fluency compared to students who received one year of intervention and the BAU group. Students in both the one- and two-year groups demonstrated similar and significantly larger gains in word reading in comparison to the BAU group. There were no statistically significant differences between the three groups on standardized measures of reading comprehension. We discuss these results in the context of research with late elementary and secondary students targeting reading comprehension.
Cognitive Profiles Associated With Responsiveness to Fraction Intervention
Krowka SK and Fuchs LS
This study examined differences in cognitive processing between 4-grade students who respond adequately, as opposed to inadequately, to intervention on 3 fraction outcomes: number-line estimation, calculation, and word problems. Students were assessed on 7 cognitive processes and on the 3 fraction outcomes. Students were grouped as adequate or inadequate responders, using as the cut-point the control-group mean on pre-to-post improvement on the relevant measure. Between-group differences identified reasoning, concept formation, and listening comprehension related to all 3 fraction outcomes. On the number-line outcome, within-group profile analysis indicated that inadequate responders experienced low reasoning ability relative to their other forms of cognitive processing.
The University Experiences of Students with Learning Disabilities
McGregor KK, Langenfeld N, Van Horne S, Oleson J, Anson M and Jacobson W
To explore the university experiences of students with learning disabilities (LD), 63,802 responses to the 2014 Student Experience in the Research University Survey were analyzed. Compared to other students, those with self-reported LD (5.96%) had difficulty with assignments and had more obstacles caused by non-academic responsibilities and imposed by their skill levels. Students with self-reported LD sensed more bias towards people with disabilities on campus, and they were less satisfied with their overall experience. Interactions between disability status and age suggested even more challenges for older students who self-reported LD. Approximately one-third of students who self-reported LD received accommodations. The rate of accommodations was higher among individuals who were wealthy, who lived alone, and who were out-of-state students. Compared to students who self-reported LD but reported no accommodations, those with accommodations had more contact with faculty and less difficulty with assignments.
Cognitive Attributes, Attention, and Self-Efficacy of Adequate and Inadequate Responders in a Fourth Grade Reading Intervention
Cho E, Roberts GJ, Capin P, Roberts G, Miciak J and Vaughn S
We examined cognitive attributes, attention, and self-efficacy of fourth grade struggling readers who were identified as adequate responders ( = 27), inadequate responders with comprehension only deficits ( = 46), and inadequate responders with comprehension and word reading deficits ( = 52) after receiving a multicomponent reading intervention. We also included typical readers ( = 40). These four groups were compared on measures of nonverbal reasoning, working memory, verbal knowledge, listening comprehension, phonological awareness, and rapid naming as well as on teacher ratings of attention problems and self-reported self-efficacy. The two inadequate responder groups demonstrated difficulties primarily with verbal knowledge and listening comprehension compared to typical readers and adequate responders. Phonological awareness and rapid naming differentiated the two inadequate responder groups. In addition, both inadequate responder groups showed more attention problems and low self-efficacy compared to typical readers.
Does Early Algebraic Reasoning Differ as a Function of Students' Difficulty with Calculations versus Word Problems?
Powell SR and Fuchs LS
According to national mathematics standards, algebra instruction should begin at kindergarten and continue through elementary school. Most often, teachers address algebra in the elementary grades with problems related to solving equations or understanding functions. With 789 2- grade students, we administered (a) measures of calculations and word problems in the fall and (b) an assessment of pre-algebraic reasoning, with items that assessed solving equations and functions, in the spring. Based on the calculation and word-problem measures, we placed 148 students into 1 of 4 difficulty status categories: typically performing, calculation difficulty, word-problem difficulty, or difficulty with calculations and word problems. Analyses of variance were conducted on the 148 students; path analytic mediation analyses were conducted on the larger sample of 789 students. Across analyses, results corroborated the finding that word-problem difficulty is more strongly associated with difficulty with pre-algebraic reasoning. As an indicator of later algebra difficulty, word-problem difficulty may be a more useful predictor than calculation difficulty, and students with word-problem difficulty may require a different level of algebraic reasoning intervention than students with calculation difficulty.
Intensive Interventions in Reading for Students with Reading Disabilities: Meaningful Impacts
Vaughn S and Wanzek J
We use three data sources to build a rationale for why intensive interventions are necessary for students with pervasive reading disabilities: current data on the performance of students with disabilities on reading achievement measures over time, observation studies on students with reading disabilities in general and special education classrooms, and findings from intensive intervention studies for students with reading disabilities. Results of these data sources indicate that students with disabilities are not making progress in reading at the same rate as students without disabilities, reading instruction for students with reading disabilities is comprised of excessive amounts of low level tasks, and findings from intensive intervention studies suggest positive impacts for students with reading disabilities. We argue that students with reading disabilities require ongoing intensive interventions that are likely to require schools to change the contexts and practices for these students.
Novel Approaches to Examine Passage, Student, and Question Effects on Reading Comprehension
Miller AC, Davis N, Gilbert JK, Cho SJ, Toste JR, Street J and Cutting LE
Reading comprehension is influenced by sources of variance associated with the reader and the task. To gain insight into the complex interplay of multiple sources of influence, we employed crossed random-effects item response models. These models allowed us to simultaneously examine the degree to which variables related to the type of passage and student characteristics influenced students' ( = 94; mean age = 11.97 years) performance on two indicators of reading comprehension: different types of comprehension questions and passage fluency. We found that variables related to word recognition, language, and executive function were influential across various types of passages and comprehension questions and also predicted a reader's passage fluency. Further, an exploratory analysis of two-way interaction effects was conducted. Results suggest that understanding the relative influence of passage, question, and student variables has implications for identifying struggling readers and designing interventions to address their individual needs.
Specific Reading Comprehension Disability: Major Problem, Myth, or Misnomer?
Spencer M, Quinn JM and Wagner RK
The goal of the present study was to test three competing hypotheses about the nature of comprehension problems of students who are poor in reading comprehension. Participants in the study were first, second, and third graders, totaling 9 cohorts and over 425,000 participants in all. The pattern of results was consistent across all cohorts: Less than one percent of first- through third-grade students who scored as poor in reading comprehension were adequate in both decoding and vocabulary. Although poor reading comprehension certainly qualifies as a major problem rather than a myth, the term specific reading comprehension disability is a misnomer: Individuals with problems in reading comprehension that are not attributable to poor word recognition have comprehension problems that are general to language comprehension rather than specific to reading. Implications for assessment and intervention are discussed.
Accurately Predicting Future Reading Difficulty for Bilingual Latino Children at Risk for Language Impairment
Petersen DB and Gillam RB
Sixty-three bilingual Latino children who were at risk for language impairment were administered reading-related measures in English and Spanish (letter identification, phonological awareness, rapid automatized naming, and sentence repetition) and descriptive measures including English language proficiency, language ability, SES, and preschool attendance at kindergarten. At the end of first grade, English word-level reading and reading comprehension were measured. Results indicated that the Spanish predictor measures did not account for significant variance over and above the English predictor measures for any of the first grade outcome measures. Of the descriptive predictor measures, only English language proficiency and language ability were significantly predictive, accounting for unique variance in first grade reading comprehension. Sensitivity ranged from .67 to .86 and specificity ranged from .82 to .93 across the four first grade outcome measures.
Relation and interactions among reading fluency and competence for adult education learners
Mellard DF, Fall EE and Woods KL
Statistical analyses of data from an academically diverse sample of 276 adult basic and secondary education learners extends understanding of the relation of and interactions between oral reading fluency and reading competence indices. Significant interactions between total word rate and word error rate that differed in relation to two measures of reading competence suggest that adult literacy instructors should emphasize fluency instruction to a greater or lesser degree depending on whether the major goal of instruction is academic reading (e.g., being able to comprehend a textbook) or functional reading (e.g., being able to fill out a job application).
Amount of Time in Print Reading in General Education Kindergarten Classrooms: What Does It Look Like for Students At-risk for Reading Difficulties?
Kent SC, Wanzek J and Al Otaiba S
The purpose of this study was to examine the amount of time spent actively engaged in reading sounds, words, and connected text for students at-risk for reading difficulties in the first formal grade of reading instruction, kindergarten. Observational data of 109 kindergarten students at high-risk for later reading difficulties were collected during general education reading instruction across the school year. Findings revealed students read orally for just over 1 minute during their reading instruction with approximately equal time spent reading sounds, words, or connected text. Implications of these results for early reading instruction and intervention for students at-risk for reading difficulties or disabilities are presented.
Early Numerical Competencies of Students with Different Forms of Mathematics Difficulty
Namkung JM and Fuchs LS
The purpose of the study was to examine differences in early numerical competencies, as well as subtraction skill, as a function of children's mathematics difficulty (MD) status: computational difficulty (CD), word problem-solving difficulty (PD), concurrent difficulty (CDPD), or neither difficulty (i.e., typically developing; TYP). Based on measures of addition and word-problem skill, second grade students (N = 332) were classified in terms of MD status. Then, students were assessed on three early numerical competency measures (Number Line Estimation, Number Sets Test, and Counting Knowledge) as well as a measure of subtraction. On Number Line Estimation and Number Sets Test, students with CD and those with PD scored comparably, but both outperformed students with CDPD. On Counting Knowledge-Double First, students with CDPD scored lower than the three contrasting groups. On subtraction, students with CD outperformed those with PD, and students with PD and those with CDPD performed comparably. Findings are discussed in terms of differential performance as a function of difficulty status and implications for understanding and teaching subtypes of MD.
Solving Word Problems using Schemas: A Review of the Literature
Powell SR
Solving word problems is a difficult task for students at-risk for or with learning disabilities (LD). One instructional approach that has emerged as a valid method for helping students at-risk for or with LD to become more proficient at word-problem solving is using schemas. A schema is a framework for solving a problem. With a schema, students are taught to recognize problems as falling within word-problem types and to apply a problem solution method that matches that problem type. This review highlights two schema approaches for 2(nd)- and 3(rd)-grade students at-risk for or with LD: schema-based instruction and schema-broadening instruction. A total of 12 schema studies were reviewed and synthesized. Both types of schema approaches enhanced the word-problem skill of students at-risk for or with LD. Based on the review, suggestions are provided for incorporating word-problem instruction using schemas.
Using Nonword Repetition Tasks for the Identification of Language Impairment in Spanish-English Speaking Children: Does the Language of Assessment Matter?
Gutiérrez-Clellen VF and Simon-Cereijido G
The purpose of this study was twofold: (a) to evaluate the clinical utility of a verbal working memory measure, specifically, a nonword repetition task, with a sample of Spanish-English bilingual children and (b) to determine the extent to which individual differences in relative language skills and language use had an effect on the clinical differentiation of these children by the measures. A total of 144 Latino children (95 children with typical language development and 49 children with language impairment) were tested using nonword lists developed for each language. The results show that the clinical accuracy of nonword repetition tasks varies depending on the language(s) tested. Test performance appeared related to individual differences in language use and exposure. The findings do not support a monolingual approach to the assessment of bilingual children with nonword repetition tasks, even if children appear fluent speakers in the language of testing. Nonword repetition may assist in the screening of Latino children if used bilingually and in combination with other clinical measures.
The Efficacy of Repeated Reading and Wide Reading Practice for High School Students with Severe Reading Disabilities
Wexler J, Vaughn S, Roberts G and Denton CA
This experimental study was conducted to examine the efficacy of repeated reading and wide reading practice interventions for high school students with severe reading disabilities. Effects on comprehension, fluency, and word reading were evaluated. Participants were 96 students with reading disabilities in grades 9-12. Students were paired within classes and pairs were randomly assigned to one of three groups: repeated reading (N = 33), wide reading (N = 34), or typical instruction (N = 29). Intervention was provided daily for approximately 15-20 minutes for 10 weeks. Results indicated no overall statistically significant differences for any condition, with effect sizes ranging from -.31 to .27. Findings do not support either approach for severely impaired readers at the high school level. We hypothesize that these students require more intensive interventions that include direct and explicit instruction in word- and text-level skills as well as engaged reading practice with effective feedback.

Phonological Awareness and Rapid Naming Skills of Children with Reading Disabilities and Children with Reading Disabilities Who Are At Risk for Mathematics Difficulties
Wise JC, Pae HK, Wolfe CB, Sevcikwe RA, Morris RD, Lovett M and Wolf M
Limited research has examined the skills of children with a reading disability (RD) and children with RD and a mathematics disability (MD). Even less research has examined the phonological awareness (PA) and rapid automatized naming (RAN) skills in these two groups of children and how these skills relate to reading and math achievement. Additionally, various classification criteria are frequently implemented to classify children with MD. The purpose of this study, therefore, was to examine the PA and RAN skills in children who met different criteria for RD only and children with RD who are at-risk for mathematics difficulties (MDR). Participants were 114 second or third grade students with RD from public elementary schools in three large metropolitan areas. Students were classified as at-risk for mathematics difficulties utilizing a 25 percentile cutoff and a 15 percentile cutoff as assessed by the KeyMath-Revised Test (Connolly, 1988). A series of PA and RAN measures were administered along with a range of reading and mathematics measures. Hierarchical regression analyses indicated that children with RD only evidenced a different pattern of results compared to children with RD + MDR. Additionally, using a more stringent criterion to classify children at-risk for mathematics difficulties resulted in a differential pattern of results when compared to a less stringent classification criterion.
Intervention Provided to Linguistically Diverse Middle School Students with Severe Reading Difficulties
Denton CA, Wexler J, Vaughn S and Bryan D
This study investigated the effectiveness of a multicomponent reading intervention implemented with middle school students with severe reading difficulties, all of whom had received remedial and/or special education for several years with minimal response to intervention. Participants were 38 students in grades 6-8 who had severe deficits in word reading, reading fluency, and reading comprehension. Most were Spanish-speaking English language learners (ELLs) with identified disabilities. Nearly all demonstrated severely limited oral vocabularies in English and, for ELLs, in both English and Spanish. Students were randomly assigned to receive the research intervention (n = 20) or typical instruction provided in their school's remedial reading or special education classes (n = 18). Students in the treatment group received daily explicit and systematic small-group intervention for 40 minutes over 13 weeks, consisting of a modified version of a phonics-based remedial program augmented with English as a Second Language practices and instruction in vocabulary, fluency, and comprehension strategies. Results indicated that treatment students did not demonstrate significantly higher outcomes in word recognition, comprehension, or fluency than students who received the school's typical instruction and that neither group demonstrated significant growth over the course of the study. Significant correlations were found between scores on teachers' ratings of students' social skills and problem behaviors and posttest decoding and spelling scores, and between English oral vocabulary scores and scores in word identification and comprehension. The researchers hypothesize that middle school students with the most severe reading difficulties, particularly those who are ELLs and those with limited oral vocabularies, may require intervention of considerably greater intensity than that provided in this study. Further research directly addressing features of effective remediation for these students is needed.
Effects of Fact Retrieval Tutoring on Third-Grade Students with Math Difficulties with and without Reading Difficulties
Powell SR, Fuchs LS, Fuchs D, Cirino PT and Fletcher JM
The purpose of this study was to assess the efficacy of fact retrieval tutoring as a function of math difficulty (MD) subtype, that is, whether students have MD alone (MD-only) or have concurrent difficulty with math and reading (MDRD). Third graders (n = 139) at two sites were randomly assigned, blocking by site and MD subtype, to four tutoring conditions: fact retrieval practice, conceptual fact retrieval instruction with practice, procedural computation/estimation instruction, and control (no tutoring). Tutoring occurred for 45 sessions over 15weeks for 15-25 minutes per session. Results provided evidence of an interaction between tutoring condition and MD subtype status for assessment of fact retrieval. For MD-only students, students in both fact retrieval conditions achieved comparably and outperformed MD-only students in the control group as well as those in the procedural computation/estimation instruction group. By contrast, for MDRD students, there were no significant differences among intervention conditions.
