Middle grade students with disabilities that impact reading, including learning disabilities (LD) in reading, high functioning autism (ASD), and emotional and behavioral disorders (EBD), and students atrisk for reading failure due to the effects of poverty often struggle to make knowledge-based inferences while reading informational texts. As a result, these populations of students are not able to read for understanding or learn from grade-level texts. Unfortunately, many special educators have had little preparation in how to develop their knowledge of "inference-making" or methods for explicitly teaching inference-making. Despite their lack of knowledge, special educators are often solely responsible for teaching skills that support reading comprehension, such as knowledge-based inference-making. This article provides special educators with information and resources to enhance their understanding of knowledge-based inferencing and methods for teaching knowledge-based inference-making to middle grade students with disabilities and those who are at risk for reading failure.

This experimental study examined the effectiveness of a text-based reading and vocabulary intervention with self-regulatory supports for 4th graders with low reading comprehension. Students with standard scores on the Gates MacGinitie Reading Test between 1.0 standard deviation (SD) and 0.5 SD below the normative sample were included (N=44) and randomly assigned to treatment condition (n=25) or no treatment comparison condition (n=19). Researchers provided the intervention to students in groups of approximately 2-3 students for eight 30 minute sessions. Students in the treatment condition made statistically significant gains on a researcher-developed measure of reading and vocabulary compared with students in the comparison condition.

Reading comprehension is an essential academic skill (Nash & Snowling, 2006;National Reading Panel, National Institute of Child Health and Human Development, 2000).Yet, among students in the eighth grade, approximately 64% of all students and 91% of students with disabilities do not read at proficient levels (National Center for Education Statistics [NCES], 2013). This suggests that when reading grade-level texts, a large percentage of middle grade readers are not able to accurately connect important ideas in text, form inferences that integrate information in text with general knowledge of the topic, and synthesize common ideas across various texts (NCES, 2013). These data highlight the need for intensive reading interventions that explicitly teach middle-grade struggling readers how to comprehend grade level texts and acquire content knowledge from the texts they read.

This experimental study examined the effectiveness of a text-based reading and vocabulary intervention with self-regulatory supports for 4th graders with low reading comprehension. Students with standard scores on the Gates MacGinitie Reading Test between 1.0 standard deviation (SD) and 0.5 SD below the normative sample were included (N=44) and randomly assigned to treatment condition (n=25) or no treatment comparison condition (n=19). Researchers provided the intervention to students in groups of approximately 2-3 students for eight 30 minute sessions. Students in the treatment condition made statistically significant gains on a researcher-developed measure of reading and vocabulary compared with students in the comparison condition.

This study investigated the reading profiles of middle school Spanish-speaking emergent bilinguals (EBs) with significantly below grade level reading comprehension and whether these profiles varied in their reading comprehension performance over time. Latent profile analyses were used to classify Grade 6 and 7 Hispanic EBs (n = 340; 39% female) into subgroups based on their word reading and vocabulary knowledge. Growth models were then fit within each profile to evaluate reading comprehension performance over time. Analyses revealed four latent profiles emerged: (a) very low word reading and low vocabulary (10%), (b) low word reading and low vocabulary (71%), (c) average word reading and low vocabulary (16%), and (d) high word reading and low vocabulary (3%). Subgroups varied in their reading comprehension initially and over one year. Students in the subgroup marked by very low word reading and low vocabulary showed the lowest reading comprehension performance initially; however, they also showed the greatest growth over one year. These findings suggest that there is heterogeneity in the reading skill profiles of Spanish-speaking EBs with reading comprehension difficulties. They also underscore the prevalence of word reading difficulties among these students. These may be important factors to consider when developing interventions to prevent and remediate these difficulties. [ABSTRACT FROM AUTHOR]

Purpose: We examined the effectiveness of a multistrategy inference intervention designed to increase inference making and reading comprehension for middle-grade struggling readers. Method: A total of 66 middle-grade struggling readers were randomized to treatment (n = 33) and comparison (n = 33) conditions. Students in the treatment group received explicit instruction in 4 inference strategies (i.e., clarification using text clues; activating and using prior knowledge; understanding character perspectives and author's purpose; answering inferential questions). In addition, narrative and informational texts were carefully chosen and sequenced to build requisite background knowledge to form inferences. Intervention was delivered in small groups of 3 students for 10 days of instruction. Results: One-way analysis of covariance models on outcome measures with the respective pretest scores as a covariate revealed significant gains on a proximal measure of Egyptian-content knowledge (g = 1.37) and on a standardized measure of reading comprehension--i.e., Wechsler Individual Achievement Test--Third Edition Reading Comprehension (g = 0.46). Conclusion: The moderate effect on a standardized measure of reading comprehension provides preliminary evidence for the effectiveness of this multistrategy inference intervention in improving reading comprehension of middle-grade struggling readers.

Difficulties suppressing previously encountered but currently irrelevant information from working memory characterize less skilled comprehenders in studies in which they are matched to skilled comprehenders on word decoding and nonverbal IQ. These "extreme" group designs are associated with several methodological issues. When sample size permits, regression approaches permit a more accurate estimation of effects. Using data for students in Grades 6 through 12 (n = 766), regression techniques assessed the significance and size of the relation of suppression to reading comprehension across the distribution of comprehension skill. After accounting for decoding efficiency and nonverbal IQ, suppression, measured by performance on a verbal proactive interference task, accounted for a small amount of significant unique variance in comprehension (less than 1%). A comparison of suppression in less skilled comprehenders matched to more skilled comprehenders (48 per group) on age, word reading efficiency, and nonverbal IQ did not show significant group differences in suppression. The implications of the findings for theories of reading comprehension and for informing comprehension assessment and intervention are discussed.

Purpose: We examined the effects of a text-processing reading comprehension intervention emphasizing listening comprehension and expressive language practices with middle school students with reading difficulties. Method: A total of 134 struggling readers in grades 6-8 were randomly assigned to treatment (n = 83) and control conditions (n = 51) using a 2:1 ratio (two students randomized to treatment for every one student randomized to control). Students in the treatment condition received 40 min of daily instruction in small groups of four to six students for approximately 17 hr. Results: One-way analysis of covariance models on outcome measures with the respective pretest scores as a covariate revealed significant gains on proximal measures of vocabulary and key word and main idea formulation. No significant differences were found on standardized measures of listening and reading comprehension. Discussion: Results provide preliminary support for integrating listening comprehension and expressive language practices within a text-processing reading comprehension intervention framework for middle-grade struggling readers.

We conducted a meta-analysis of 28 studies comprising 39 samples to ask the question, "What is the magnitude of the association between various baseline child cognitive characteristics and response to reading intervention?" Studies were located via literature searches, contact with researchers in the field, and review of references from the National Reading Panel Report. Eligible participant populations included at-risk elementary school children enrolled in the third grade or below. Effects were analyzed using a shifting unit of analysis approach within three statistical models: cognitive characteristics predicting growth curve slope (Model 1, mean r = 0.31), gain (Model 2, mean r = 0.21), or postintervention reading controlling for preintervention reading (Model 3, mean r = 0.15). Effects were homogeneous within each model when effects were aggregated within study. The small size of the effects calls into question the practical significance and utility of using cognitive characteristics for prediction of response when baseline reading is available.

Separate mixed model analyses of variance were conducted to examine the effect of textual distance on the accuracy and speed of text consistency judgments among adequate and struggling comprehenders across grades 6-12 (n = 1,203). Multiple regressions examined whether accuracy in text consistency judgments uniquely accounted for variance in comprehension. Results suggest that there is considerable growth across the middle and high school years, particularly for adequate comprehenders in those text integration processes that maintain local coherence. Accuracy in text consistency judgments accounted for significant unique variance for passage-level, but not sentence-level comprehension, particularly for adequate comprehenders.

We evaluated the technical adequacy of oral reading fluency (ORF) probes in which 1,472 middle school students with and without reading difficulties read fluency probes for 60 s versus reading the full passage. Results suggested that the reliability of 60-s probes (rs = 0.75) was not substantively different than full passage probes (rs = 0.77) among struggling readers and typically developing readers in Grades 6 to 8. The correlation of 60-s and the full passage probes with norm-referenced measures of ORF ranged from 0.32 to 0.83, and the correlation with norm-referenced measures of reading comprehension ranged from 0.32 to 0.54, indicating that both measures were moderately valid and adequate for use among middle school students. Last, full passage probes with sensitivity rates ranging from 0.40 to 0.45 were only slightly more sensitive for identifying at-risk readers than 60-s probes, with sensitivity rates ranging from 0.36 to 0.40, suggesting that the full passage probes identified a slightly higher percentage of at-risk students with reading difficulties.

No studies have investigated the cognitive attributes of middle school students who are adequate and inadequate responders to Tier 2 reading intervention. We compared students in Grades 6 and 7 representing groups of adequate responders (n = 77) and inadequate responders who fell below criteria in (a) comprehension (n = 54); (b) fluency (n = 45); and (c) decoding, fluency, and comprehension (DFC; n = 45). These students received measures of phonological awareness, listening comprehension, rapid naming, processing speed, verbal knowledge, and nonverbal reasoning. Multivariate comparisons showed a significant Group-by-Task interaction: the comprehension-impaired group demonstrated primary difficulties with verbal knowledge and listening comprehension, the DFC group with phonological awareness, and the fluency-impaired group with phonological awareness and rapid naming. A series of regression models investigating whether responder status explained unique variation in cognitive skills yielded largely null results consistent with a continuum of severity associated with level of reading impairment, with no evidence for qualitative differences in the cognitive attributes of adequate and inadequate responders.

We evaluated the effects of student characteristics (sight word reading efficiency, phonological decoding, verbal knowledge, level of reading ability, grade, gender) and text features (passage difficulty, length, genre, and language and discourse attributes) on the oral reading fluency of a sample of middle-school students in Grades 6-8 (N = 1,794). Students who were struggling (n = 704) and typically developing readers (n = 1,028) were randomly assigned to read five 1-min passages from each of 5 Lexile bands (within student range of 550 Lexiles). A series of multilevel analyses showed that student and text characteristics contributed uniquely to oral reading fluency rates. Student characteristics involving sight word reading efficiency and level of decoding ability accounted for more variability than reader type and verbal knowledge, with small, but statistically significant effects of grade and gender. The most significant text feature was passage difficulty level. Interactions involving student text characteristics, especially attributes involving overall ability level and difficulty of the text, were also apparent. These results support views of the development of oral reading fluency that involve interactions of student and text characteristics and highlight the importance of scaling for passage difficulty level in assessing individual differences in oral reading fluency.

Purpose: Agreement across methods for identifying students as inadequate responders or as learning disabled is often poor. We report (1) an empirical examination of final status (postintervention benchmarks) and dual-discrepancy growth methods based on growth during the intervention and final status for assessing response to intervention and (2) a statistical simulation of psychometric issues that may explain low agreement. Methods: After a Tier 2 intervention, final status benchmark criteria were used to identify 104 inadequate and 85 adequate responders to intervention, with comparisons of agreement and coverage for these methods and a dual-discrepancy method. Factors affecting agreement were investigated using computer simulation to manipulate reliability, the intercorrelation between measures, cutoff points, normative samples, and sample size. Results: Identification of inadequate responders based on individual measures showed that single measures tended not to identify many members of the pool of 104 inadequate responders. Poor to fair levels of agreement for identifying inadequate responders were apparent between pairs of measures. In the simulation, comparisons across 2 simulated measures generated indices of agreement (?) that were generally low because of multiple psychometric issues inherent in any test. Conclusions: Expecting excellent agreement between 2 correlated tests with even small amounts of unreliability may not be realistic. Assessing outcomes based on multiple measures, such as level of curriculum-based measure performance and short normreferenced assessments of fluency, may improve the reliability of diagnostic decisions.

Considerable research evidence supports the provision of explicit instruction for students at risk for reading difficulties; however, one of the most widely implemented approaches to early reading instruction is Guided Reading (GR; Fountas & Pinnel, 1996), which deemphasizes explicit instruction and practice of reading skills in favor of extended time reading text. This study evaluated the two approaches in the context of supplemental intervention for at-risk readers at the end of Grade 1. Students (n = 218) were randomly assigned to receive GR intervention, explicit intervention (EX), or typical school instruction (TSI). Both intervention groups performed significantly better than TSI on untimed word identification. Significant effects favored EX over TSI on phonemic decoding and one measure of comprehension. Outcomes for the intervention groups did not differ significantly from each other; however, an analysis of the added value of providing each intervention relative to expected growth with typical instruction indicated that EX is more likely to substantially accelerate student progress in phonemic decoding, text reading fluency, and reading comprehension than GR. Implications for selection of Tier 2 interventions within a response-to-intervention format are discussed.

This article describes a randomized controlled trial conducted to evaluate the effects of an intensive, individualized, Tier 3 reading intervention for second grade students who had previously experienced inadequate response to quality first grade classroom reading instruction (Tier 1) and supplemental small-group intervention (Tier 2). Also evaluated were cognitive characteristics of students with inadequate response to intensive Tier 3 intervention. Students were randomized to receive the research intervention (N = 47) or the instruction and intervention typically provided in their schools (N = 25). Results indicated that students who received the research intervention made significantly better growth than those who received typical school instruction on measures of word identification, phonemic decoding, and word reading fluency and on a measure of sentence- and paragraph-level reading comprehension. Treatment effects were smaller and not statistically significant on phonemic decoding efficiency, text reading fluency, and reading comprehension in extended text. Effect sizes for all outcomes except oral reading fluency met criteria for substantive importance; however, many of the students in the intervention continued to struggle. An evaluation of cognitive profiles of adequate and inadequate responders was consistent with a continuum of severity (as opposed to qualitative differences), showing greater language and reading impairment prior to the intervention in students who were inadequate responders.

This study investigated how measures of decoding, fluency, and comprehension in middle school students overlap with one another, whether the pattern of overlap differs between struggling and typical readers, and the relative frequency of different types of reading difficulties. The 1,748 sixth, seventh, and eighth grade students were oversampled for struggling readers (n = 1,025) on the basis of the state reading comprehension proficiency measure. Multigroup confirmatory factor analyses showed partial invariance among struggling and typical readers (with differential loadings for fluency and for comprehension), and strict invariance for decoding and a combined fluency/comprehension factor. Among these struggling readers, most (85%) also had weaknesses on nationally standardized measures, particularly in comprehension; however, most of these also had difficulties in decoding or fluency. These results show that the number of students with a specific comprehension problem is lower than recent consensus reports estimate and that the relation of different reading components varies according to struggling versus proficient readers.

This study used multigroup structural equations to evaluate the possibility that a theory-driven, evidence-based, yearlong reading program for sixth-grade struggling readers moderates the interrelationships among elements of the simple model of reading (i.e., listening comprehension, word reading, and reading comprehension; Hoover & Gough, 1990). Our specific interest was in the relation of theory, program, and evaluation. Our motivating assumptions were that 1) a well-designed, theory-based program affects performance in predictable ways and that 2) treatment effects may be present even when group differences in posttest means are not robust. The analysis sample comprised 327 students, 113 in the business-as-usual condition and 214 in treatment. We pretested students in the fall of sixth grade and collected posttest data in the fall of seventh grade. There were 217 cases in the posttest sample, 47 comparison students and 170 treatment students at posttest. The findings support the possibility that treated sixth-grade students improved in response to an intensive, yearlong intervention, when conceptualizing change in terms of predictable interrelationships of important underlying skills, rather than in terms of group mean differences at posttest. Specifically, the results suggest that verbal knowledge is less proximal to the reading comprehension of students who have become proficient in the use of text processing and reading comprehension strategies.

Maze tasks have appealing properties as progress-monitoring tools, but there is a need for a thorough examination of the psychometric properties of Maze tasks among middle school students. We evaluated form effects, reliability, validity, and practice effects of Maze among students in Grades 6 through 8. We administered the same (familiar) and novel Maze passages for progress monitoring of a reading intervention among typical readers (n = 588), struggling readers receiving researcher-provided intervention (n = 471), and struggling readers not receiving intervention (n = 284). Form effects accounted for significant variance in Maze performance. Familiar passages had greater test-retest reliability than novel passages. Both administrative conditions had similar, moderate correlations (validity coefficients) with other measures of reading fluency and comprehension. There were also significant practice effects. Students who read the same passage showed steeper slopes in Maze performance than students who read different passages over time. Practice effects were influenced by beginning levels of reading comprehension and by intervention status. (Contains 1 note, 6 tables, and 1 figure.)

We evaluated the reliability and validity of two oral reading fluency scores for 1-minute equated passages: median score and mean score. These scores were calculated from measures of reading fluency administered up to five times over the school year to students in grades six to eight (n = 1,317). Both scores were highly reliable with strong convergent validity for adequately developing and struggling middle grade readers. These results support the use of either the median or mean score for oral reading fluency assessments for middle grade readers. (Contains 11 tables.)

The cognitive attributes of Grade 1 students who responded adequately and inadequately to a Tier 2 reading intervention were evaluated. The groups included inadequate responders based on decoding and fluency criteria (n = 29), only fluency criteria (n = 75), adequate responders (n = 85), and typically achieving students (n = 69). The cognitive measures included assessments of phonological awareness, rapid letter naming, oral language skills, processing speed, vocabulary, and nonverbal problem solving. Comparisons of all four groups identified phonological awareness as the most significant contributor to group differentiation. Measures of rapid letter naming, syntactic comprehension/working memory, and vocabulary also contributed uniquely to some comparisons of adequate and inadequate responders. In a series of regression analyses designed to evaluate the contributions of responder status to cognitive skills independently of variability in reading skills, only the model for rapid letter naming achieved statistical significance, accounting for a small (1%) increment in explained variance beyond that explained by models based only on reading levels. Altogether, these results do not suggest qualitative differences among the groups, but are consistent with a continuum of severity associated with the level of reading skills across the four groups. (Contains 3 figures and 4 tables.)

The purpose of this study was to investigate the relations among oral and silent reading fluency and reading comprehension for students in Grades 6 to 8 (n = 1,421) and the use of fluency scores to identify middle school students who are at risk for failure on a high-stakes reading test. Results indicated moderate positive relations between measures of fluency and comprehension. Oral reading fluency (ORF) on passages was more strongly related to reading comprehension than ORF on word lists. A group-administered silent reading sentence verification test approximated the classification accuracy of individually administered ORF passages. The correlation between a maze task and comprehension was weaker than has been reported for elementary students. The best predictor of a high-stakes reading comprehension test was the previous year's administration of the grade-appropriate test; fluency and verbal knowledge measures accounted for only small amounts of unique variance beyond that accounted for by the previous year's administration. (Contains 3 tables.)

This study compared the effects on reading outcomes of delivering supplemental, small-group intervention to first-grade students at risk for reading difficulties randomly assigned to one of three different treatment schedules: extended (4 sessions per week, 16 weeks; n = 66), concentrated (4 sessions per week, 8 weeks; n = 64), or distributed (2 sessions per week, 16 weeks; n = 62) schedules. All at-risk readers, identified through screening followed by 8 weeks of oral reading fluency (ORF) progress monitoring, received the same Tier 2 reading intervention in groups of 2 to 4 beginning in January of Grade 1. Group means were higher in word reading and ORF at the final time point relative to pretest; however, the groups did not differ significantly on any reading outcome or on rates of adequate intervention response. Of potential covariates, site, age, free lunch status, program coverage rate, and tutor were significantly related to student outcomes; however, the addition of these variables in multivariate models did not substantially change results. Rates of adequate intervention response were lower than have been reported for some first-grade interventions of longer duration. (Contains 3 tables.)

A meta-analysis of 22 studies evaluating the relation of different assessments of IQ and intervention response did not support the hypothesis that IQ is an important predictor of response to instruction. We found an R[superscript 2] of 0.03 in models with IQ and the autoregressor as predictors and a unique lower estimated R[superscript 2] of 0.006 and a higher estimated R[superscript 2] of 0.013 in models with IQ the autoregressor, and additional covariates as predictors. There was no evidence that these aggregated effect sizes were moderated by variables such as the type of IQ measure, outcome, age, or intervention. In simulations of the capacity of variables with effect sizes of 0.03 and 0.001 for predicting response to intervention, we found little evidence of practical significance. (Contains 1 figure and 4 tables.)

The authors examine the reassessments of the National Reading Panel (NRP) report (National Institute of Child Health and Human Development, 2000) by G. Camilli, S. Vargas, and M. Yurecko (2003); G. Camilli, P. M. Wolfe, and M. L. Smith (2006); and D. D. Hammill and H. L. Swanson (2006) that disagreed with the NRP on the magnitude of the effect of systematic phonics instruction. Using the coding of the NRP studies by Camilli et al. (2003, 2006), multilevel regression analyses show that their findings do not contradict the NRP findings of effect sizes in the small to moderate range favoring systematic phonics. Extending Camilli et al. (2003, 2006), the largest effects are associated with reading instruction enhanced with components that increase comprehensiveness and intensity. In contrast to Hammill and Swanson, binomial effect size displays show that effect sizes of the magnitude found for systematic phonics by the NRP are meaningful and could result in significant improvement for many students depending on the base rate of struggling readers and the size of the effect. Camilli et al. (2003, 2006) and Hammill and Swanson do not contradict the NRP report, concurring in supporting comprehensive approaches to reading instruction.

In order to better understand the extent to which operationalizations of response to intervention (RTI) overlap and agree in identifying adequate and inadequate responders, an existing database of 399 first grade students was evaluated in relation to cut-points, measures, and methods frequently cited for the identification of inadequate responders to instruction. A series of 543 2x2 measures of association (808 total comparisons) were computed to address the agreement of different operationalizations of RTI. The results indicate that agreement is generally poor and that different methods tend to identify different students as inadequate responders, although agreement for identifying adequate responders is higher. Approaches to the assessment of responder status must use multiple criteria and avoid formulaic decision making. (Contains 8 tables.)

A meta-analysis of 22 studies evaluating the relation of different assessments of IQ and intervention response did not support the hypothesis that IQ is an important predictor of response to instruction. We found an [R.sup.2] of .03 in models with IQ and the autoregressor as predictors and a unique lower estimated [R.sup.2] of. 006 and a higher estimated Re of. 013 in models with IQ, the autoregressor, and additional covariates as predictors. There was no evidence that these aggregated effect sizes were moderated by variables such as the type of IQ measure, outcome, age, or intervention. In simulations of the capacity of variables with effect sizes of .03 and .001 for predicting response to intervention, we found little evidence of practical significance., The role of IQ test scores for the identification of children with learning disabilities (LD) continues to be controversial. This controversy was highlighted by the 2004 reauthorization of the Individuals [...]
