Very preterm children, children with learning disability, and typically developing children were compared in mathematics skills, using standardized tools, experimental tasks, and eye-tracker measures. We assessed symbolic and nonsymbolic magnitude comparisons, number knowledge, calculation, as well as cognitive skills of 103 Italian-speaking fourth and fifth graders. Compared to typically developing peers, very preterm children showed delays in number knowledge, slower reaction times in nonsymbolic magnitude comparisons, and an atypical gaze exploration characterized by more and shorter fixations that lacked a target preference. The profile of mathematics skills of very preterm children appeared different from that of children with learning disability. Although both populations showed mainly preserved cognitive skills and slower reaction times in nonsymbolic magnitude comparisons, children with specific learning disability showed more severe impairments in calculation and were slower in symbolic magnitude comparisons, compared to very preterm children. Including eye-tracking measures in preterm follow-up programs and planning tailored interventions are recommended.

The Open Science movement tries to increase trust in research results and open the access to all elements of a research project to the public. Central to these goals, Open Science has promoted five critical tenets: Open Data, Open Analysis, Open Materials, Preregistration, and Open Access. All Open Science elements can be thought of as extensions to the traditional way of achieving openness in science, which has been scientific publication of research outcomes in journals or books. Open Science in education sciences, however, has the potential to be much more than a safeguard against questionable research. Open Science in education science provides opportunities to (a) increase the transparency and therefore replicability of research and (b) develop and answer research questions about individuals with learning disabilities and learning difficulties that were previously impossible to answer due to complexities in data analysis methods. We will provide overviews of the main tenets of Open Science (i.e., Open Data, Open Analysis, Open Materials, Preregistration, and Open Access), show how they are in line with grant funding agencies' expectations for rigorous research processes, and present resources on best practices for each of the tenets.

To investigate whether FFT promotes instruction that appropriately responds to the needs of students with learning disabilities, we conduct a systematic content analysis of the instructional approach emphasized in the FFT's Instructional Domain (Domain 3) of Danielson's FFT. We frame our study using cognitive load theory and research regarding effective instruction for students with disabilities. We end by discussing implications regarding the evaluation and development of effective teaching for students with learning disabilities.

A majority of teachers reported making the following adaptations for their weakest writers at least once a week: individual tutoring, assistance from a peer when writing, and extra instruction in grammar/spelling, planning/revising, handwriting, sentence construction, and text structure. On a monthly basis or more often, a majority of teachers reported they provided weaker writers with choice about writing assignments, the opportunity to complete an alternative writing assignment, and extra writing instruction via computer technology. How often an adaptation was applied did not differ by grade. The perceived adequacy of teacher undergraduate preparation to teach writing, their efficacy to teach writing, and the proportion of students with disability in their classes each made a unique and statistically significant contribution to predicting how frequently teachers applied adaptations for their weakest writers. The Chilean teachers in this study reportedly made adaptations for weaker writers in their class more often than teachers in studies conducted in other countries, including the United States.

Data were collected on 265 at-risk readers' word reading prior to and immediately following program implementation in first grade and in spring of second grade. Pretreatment data were also obtained on domain-specific skills (letter knowledge, decoding, passage comprehension, language) and domain-general skills (working memory, non-verbal reasoning). Latent profile analysis of word reading across the three time points with controls as a local norm revealed a group ( = 45) with mean word-reading scores of 0.25, 1.64, and 1.26 at the three time points, respectively; a group ( = 109), scores = 0.30, 0.47, and 0.55; a group ( = 90), scores = -0.11, -0.15, and -0.55; and a group ( = 21), scores = -1.24, -1.26, and -1.57. The two responsive groups had stronger pretreatment letter knowledge and passage comprehension than the two non-responsive groups. The mildly non-responsive group demonstrated better pretreatment passage comprehension than the strongly non-responsive group. No domain-general skill distinguished the four groups. Findings suggest response to early reading intervention was more complicated than response/no response, and pretreatment reading comprehension was an important predictor of response even with pretreatment word reading controlled.

With students in Grades 6 to 8 with reading difficulties, dominance analyses examined the differential importance of component reading and language skills (word- and text-reading fluency, vocabulary, listening comprehension, and working memory) on several standardized tests of reading comprehension: , 4th edition (GMRT), , , 5th edition (GORT-5), and the (TOSREC). Students' word- and text-reading fluency skills were generally the most dominant predictors of performance on most reading comprehension tests, especially those with a time limit (GMRT and TOSREC). Listening comprehension was most important on the GORT-5, a test in which students read passages orally and listen to questions read by an examiner. Working memory was the least important component skill across the reading comprehension tests. Overall, results were consistent with previous work indicating that reading comprehension measures vary with regard to the skills or knowledge sources that are most important for test performance and extend these findings to struggling adolescent readers. Implications for research and practice are discussed.

A total of 48 students with MD were randomly assigned to either the algebraic equation solving intervention, ( = 24) or control condition ( = 24). The multicomponent intervention was based on the principles of explicit instruction and focused on improving conceptual and procedural knowledge of algebraic equation solving using concrete manipulatives. Students in the intervention group received instruction in pairs, 30 min per session, 3 sessions per week for 5 weeks (i.e., 15 sessions). The results indicated that the main effect of intervention was significant for 2 proximal measures of mathematics vocabulary, and conceptual and procedural understanding of algebraic equation solving with large effect sizes. However, the main effect of intervention was not significant for distal measures of comprehensive pre-algebra skills and whole-number computations. The findings demonstrate that grade-level standards can be successfully taught to students with MD. Implications for practice are discussed.

During Year 1, teachers taught 48 words to their sixth grade students, who learned and retained the words significantly better than the students in business-as-usual (BAU) control classes. In the current study, we report the second year results, as the sixth grade students entered seventh grade. Students ( = 42) in treatment classes again learned 48 new vocabulary words significantly better than similar students in BAU ( = 21) special education classes. In seventh grade, students also outperformed BAU students on maintenance of these age-appropriate words ( < .001) and on a standardized measure of vocabulary ( = .04).

Because states guide and regulate policy and practice at the state and local education agency levels, it is important to understand their critical role in RTI implementation. A systematic review of all 50 state education agency websites was conducted to provide an updated "snapshot" of states' interpretation of RTI a decade after IDEA regulations were finalized. Findings revealed substantive progress towards developing approaches to systematic supports to students, with a major trend in adoption of multi-tiered system of support (MTSS) models. Findings also documented continued variation in how states are communicating about tiered systems on such matters as the roles of tiered systems in schoolwide prevention frameworks, meeting special education requirements, and aligning multiple systems within schools. Implications for special education services for students with learning disabilities are discussed.

Nevertheless, important unresolved questions remain about its role in disability identification. We had two purposes when conducting this study of 229 economically and racially diverse poor readers in Grades 4 and 5 in 28 public elementary and middle schools in Nashville. First, we examined predictors of the children's response to a reading comprehension tutoring program. Second, we explored the utility of different methods (growth vs final status) and measures (near- and mid-transfer vs far-transfer) in operationalizing "response," and whether these contrasting methods and measures identified similar children. Findings indicated students with higher pretreatment scores on expressive vocabulary, nonverbal IQ, teacher ratings of attention, and reading comprehension measures were more likely classified as responsive with final status methods. Students with lower pretreatment comprehension scores were more likely identified as responsive with growth methods. These and other findings suggest "response" is strongly context dependent, raising questions about the validity of RTI as a means of disability identification.

A definitive answer to this question has been elusive because of the continuous distribution of reading performance and predictors of dyslexia and because of the heterogeneous nature of samples of poor readers. Samples of poor readers are a mixture of individuals whose reading is consistent with or expected based on their performance in other academic areas and in language, and individuals with dyslexia whose reading is not consistent with or expected based on their other performances. In the present article, we replicate and extend a new approach for determining the prevalence of dyslexia. Using model-based meta-analysis and simulation, three main results were found. First, the prevalence of dyslexia is better represented as a distribution that varies as a function of severity as opposed to any single-point estimate. Second, samples of poor readers will contain more expected poor readers than unexpected or dyslexic readers. Third, individuals with dyslexia can be found across the reading spectrum as opposed to only at the lower tail of reading performance. These results have implications for screening and identification, and for recruiting participants for scientific studies of dyslexia.

Yet, the field of special education has not provided observation protocols designed specifically for preservice teachers that are founded in theoretical perspectives and research on effective instruction for students with learning and other high-incidence disabilities (SWDs). To address this need, a group of researchers in special education teacher preparation and measurement developed the Preservice Observation Instrument for Special Education (POISE). The POISE is an observation system rooted in effective special education practices that support the growth of preservice teachers who will serve SWD across instructional settings. The purpose of this article is to report on the development and psychometric properties of the POISE. Specifically, we employed Kane's argument-based validity approach to frame each stage in the development process of the POISE. We conducted two phases of content validation activities, development activities, and a pilot study to assess the degree to which scores from POISE provided evidence for the scoring, generalizability, and extrapolation inferences. In the end, the POISE represents a promising observation instrument for the development of special education teacher candidates.

Participants were 499 second- and third-grade students in six urban schools. Students who scored at or below the 10th percentile on the fall reading screening assessment were identified as having a severe reading deficit and received a tier 2 reading intervention that was targeted to their needs. Results showed a significant effect between groups on reading growth. Students with severe reading deficits receiving targeted tier 2 intervention grew at a rate that equaled the rate of growth of students without reading deficits and was significantly higher than students who were receiving special education services for reading. Implications for practice, suggestions for future research, and study limitations are discussed.

We included studies comparing children with SLI to (a) typically developing peers matched on age ( = 39 studies) and (b) typically developing younger peers with similar language capabilities ( = six studies). Children classified with SLI scored lower on writing measures than their typically developing peers matched on age ( = -0.97) when all writing scores in a study were included in the analysis. This same pattern occurred for specific measures of writing: quality ( = -0.92), output ( = -1.00), grammar ( = -0.68), vocabulary ( = -0.68), and spelling ( = -1.17). A moderator analysis revealed that differences in the writing scores of children classified with SLI and typically developing peers matched on age were not as large, but were still statistically significant, when assessment involved a contrived response format (vs. measured based on students' writing), researcher-created measures (vs. norm-referenced tests), or SLI included just children with a speech disorder (vs. children with a language disorder). Children classified with SLI further scored lower on writing than typically developing peers with similar language capabilities ( = -0.47). We concluded that children with SLI experience difficulties with writing.

However, in the three states that mandate child-level reporting, data indicate lower than expected rates of dyslexia identification when compared with commonly accepted dyslexia prevalence rates. To better understand this apparent mismatch, this study explores factors that might predict the school-assigned identification of individuals with dyslexia. Deidentified data on 7,947 second-grade students in 126 schools from one U.S. state included a universal screening measure of literacy skills indicative of dyslexia (i.e., reading and spelling), school-assigned dyslexia classification, and demographic characteristics. As expected, behavioral characteristics of dyslexia from universal screening were associated with school-assigned dyslexia classification. However, dyslexia classification was less likely for minority students and individuals attending schools with a higher percentage of minority students. Students who showed behavioral characteristics of dyslexia and attended schools with a higher proportion of other students with similar poor literacy skills were more likely to receive a school-assigned dyslexia classification. The findings suggest systematic demographic differences in whether a student is identified with dyslexia by schools even when using universal screening.

Participants included 11 elementary grade teachers who delivered intensive intervention in early writing and their students ( = 31), all identified as either at risk for or with disabilities that affect their writing. Teachers received professional development and ongoing coaching to support the implementation of DBI for improving their students' early writing skills. Results from a multiple regression analysis suggest that teacher knowledge and skills in DBI was strongly related to student CBM slope in early writing ( < .01) and a small but significant relation between fidelity of writing instruction and student CBM slope ( < .01). Implications for instructional coaching and improving student writing progress are discussed.

This is commonly explained by social exclusion or withdrawal from peers, but underlying mechanisms are not well understood. This study uses sibling data to investigate if the comorbidity between language difficulties and internalizing problems is best explained by familial factors shared by siblings, such as genes or family environment, or nonfamilial factors specific to each child, such as peer environment. Data include 5,568 siblings at 5 years and 3,654 siblings at 8 years participating in the Norwegian Mother, Father and Child Cohort Study (MoBa). We constructed a latent factor model at 5 and 8 years, including a family comorbidity factor capturing correlations between language and internalizing problems that were equally strong between as within siblings. Results showed that the correlation between one sibling's internalizing problems and the other sibling's language problems was mostly accounted for by a family comorbidity factor. The best-fitting longitudinal model included stability of the family comorbidity factor and stability of language and internalizing problems within each sibling and no cross-sibling or cross-trait longitudinal associations. This suggests that the association between language and internalizing problems may be best explained by family factors.
