The quality of teaching behaviors in learning environments of DHH students.

Classrooms are complex learning environments, with instruction, climate, and teacher-student interactions playing important roles in students' academic progress. To investigate the learning environments of deaf and hard-of-hearing (DHH) students, we developed a new observational tool called the Quality of the Learning Environment-DHH rating scale (QLE-DHH) and rated 98 teachers of DHH students being educated in a range of classroom environments. The present study sought to (1) determine if the items on the QLE-DHH are good indicators of theoretically meaningful dimensions of classroom quality; (2) determine to what extent these dimensions predicted language and reading outcomes of DHH students; and (3) examine how teachers of DHH students were rated on the indicators of classroom quality. The findings suggested that the QLE-DHH has excellent structural validity. Ratings predicted student reading outcomes. Finally, the QLE-DHH was able to capture teachers' strengths and skills in need of improvement. The QLE-DHH appears to hold promise for use in both research and teacher preparation programs.

Writing knowledge, practices, efficacy, interests, attitudes, and beliefs of deaf education teachers: a randomized controlled trial.

Writing teachers play an extraordinarily important role in their students' writing development. Teachers' motivational beliefs, such as attitudes toward writing, perceptions of their efficacy to teach writing, or preparation to use evidence-based instructional practices, impact their writing instruction, which directly affects the advancement of students' writing skills. Deaf writers are a subpopulation of writers who may face discriminatory beliefs toward their writing development stemming from ableism, audism, or linguicism. Deaf education teachers may doubt their abilities to teach bilingual/multilingual students or teach deaf students experiencing language deprivation. The current study investigates whether deaf education teachers' beliefs can be fostered through an intensive one-year professional development (PD) program designed specifically for deaf education teachers. In this randomized controlled trial, we examine the extent to which the participation of deaf education teachers in specialized PD and subsequent writing instruction implementation (n = 26) impacts their pedagogical content knowledge, use of evidence-based practices for teaching writing, interest, attitudes, efficacy in teaching writing, and epistemological beliefs about writing compared to teachers in a business as usual condition (n = 24). Pre-post regression analyses indicate statistically significant group differences (with the treatment group scoring higher) on all variables except attitude and some epistemological beliefs. We speculate that specialized, sustained PD paired with supported implementation of writing instruction and ongoing teacher reflection are contributing factors to changes in teachers' motivational beliefs.

Pandemic effects on the reading trajectories of deaf and hard of hearing students: a pilot analysis.

It is important to understand the nature of the effect that the COVID-19 pandemic had upon student learning, especially those at risk such as deaf students. The limited communication that many deaf students have at home may mean less support is available for learning remotely. Reading may be one of the areas where progress was diminished. We collected Measures of Academic Progress (MAP) scores in reading from deaf students in a residential school for the deaf in grades 3 to 12 every fall and spring from 2016 to 2021. A cohort-sequential approach yielded growth data (2570 observations), with 546 students measured up to 10 times each. As is typical of MAP reading achievement in grades 3 to 12, growth was steep in early grades, slowing in later grades. Students in the Alternative Curriculum performed lower and grew slower. Cohorts differed, with more recent cohorts typically having higher performance than older cohorts. Tenure had a substantial effect, suggesting that students who had been in the school for the deaf longer had higher performance compared to students who joined the school as older students. The pandemic appeared to have a strong, but diminishing effect in each semester, but this effect differed widely across demographic groups. This suggests that effects of the pandemic are neither clear nor simple for deaf students even within the same school. These findings have implications for understanding how the impact of pandemic may vary as a function of deaf students' educational experiences and other demographic factors.

Sex differences in social communication behaviors in toddlers with suspected autism spectrum disorder as assessed by the ADOS-2 toddler module.

LAY ABSTRACT: When toddlers are suspected of autism spectrum disorder (ASD), the gold-standard assessment technique is with the Autism Diagnostic Observation Schedule, 2nd edition (ADOS-2) Toddler Module, a behavioral observation system. ASD is a neurodevelopmental condition more frequently diagnosed in toddler boys than in toddler girls. There is some evidence that the ADOS-2 assesses behaviors that are more characteristic of boys with ASD than girls. Thus, it is possible that focusing on these behaviors contributes at least in part to why more boys are diagnosed than girls. Specifically, girls may show more social skills than boys during the ADOS-2 assessment due to their socialization histories, which may lead to missed diagnoses of ASD in toddler girls. The current study examined eight social behaviors assessed by the ADOS-2 in a sample of toddlers with suspected ASD to see if they contributed differently to the total score of those items. Examination of those items suggested that those social communication behaviors work the same for boys and girls with suspected ASD, which was inconsistent with hypotheses. However, examination of particular items raises the possibility of examining creative/imaginative play as an area for future research.

What's in a face? The role of facial features in ratings of dominance, threat, and stereotypicality.

Faces judged as stereotypically Black are perceived negatively relative to less stereotypical faces. In this experiment, artificial faces were constructed to examine the effects of nose width, lip fullness, and skin reflectance, as well as to study the relations among perceived dominance, threat, and Black stereotypicality. Using a multilevel structural equation model to isolate contributions of the facial features and the participant demographics, results showed that stereotypicality was related to wide nose, darker reflectance, and to a lesser extent full lips; threat was associated with wide nose, thin lips, and low reflectance; dominance was mainly related to nose width. Facial features explained variance among faces, suggesting that face-type bias in this sample was related to specific face features rather than particular characteristics of the participant. People's perceptions of relations across these traits may underpin some of the sociocultural disparities in treatment of certain individuals by the legal system.

Language and Reading Progress of Young Deaf and Hard-of-Hearing Children.

We examined the language and reading progress of 336 young DHH children in kindergarten, first and second grades. Trained assessors tested children's language, reading, and spoken and fingerspelled phonological awareness in the fall and spring of the school year. Children were divided into groups based on their auditory access and classroom communication: a spoken-only group (n = 101), a sign-only group (n = 131), and a bimodal group (n = 104). Overall, children showed delays in language and reading compared to norms established for hearing children. For language, vocabulary standard scores were higher than for English syntax. Although delayed in language, children made expected gains based on hearing norms from kindergarten to second grade. Reading scores declined from kindergarten to second grade. Spoken-only and bimodal children had similar word reading and reading comprehension abilities and higher scores than sign-only children. Spoken-only children had better spoken phonological awareness and nonword reading skills than the other two groups. The sign-only and bimodal groups made similar and significant gains in ASL syntax and fingerspelling phonological awareness.

The Relation Between Dialect Density and the Codevelopment of Writing and Reading in African American Children.

The purpose of this longitudinal study was to examine the influence of spoken dialect density on writing and on the codevelopment of reading and writing in African American English-speaking (AAE) children from first through fifth grades. The sample included 869 students, ranging in age from 5.8 to 12.5 years. Results indicated that dialect density had a negative influence concurrently and longitudinally on reading and writing in AAE-speaking children. High dialect users tended to have weak reading and writing skills and heavier dialect density slowed growth in reading and writing. However, this effect was moderated by the effects of reading and writing on each other. Reading had a facilitative effect on writing even in the presence of heavy dialect use.

Modality and Interrelations Among Language, Reading, Spoken Phonological Awareness, and Fingerspelling.

Better understanding of the mechanisms underlying early reading skills can lead to improved interventions. Hence, the purpose of this study was to examine multivariate associations among reading, language, spoken phonological awareness, and fingerspelling abilities for three groups of deaf and hard-of-hearing (DHH) beginning readers: those who were acquiring only spoken English (n = 101), those who were visual learners and acquiring sign (n = 131), and those who were acquiring both (n = 104). Children were enrolled in kindergarten, first, or second grade. Within-group and between-group confirmatory factor analysis showed that there were both similarities and differences in the abilities that underlie reading in these three groups. For all groups, reading abilities related to both language and the ability to manipulate the sublexical features of words. However, the groups differed on whether these constructs were based on visual or spoken language. Our results suggest that there are alternative means to learning to read. Whereas all DHH children learning to read rely on the same fundamental abilities of language and phonological processing, the modality, levels, and relations among these abilities differ.

Developing a Longitudinal Scale for Language: Linking Across Developmentally Different Versions of the Same Test.

Purpose Many language tests use different versions that are not statistically linked or do not have a developmental scaled score. The current article illustrates the problems of scores that are not linked or equated, followed by a statistical model to derive a developmental scaled score. Method Using an accelerated cohort design of 890 students in Grades 1-5, a confirmatory factor model was fit to 6 subtests of the Test of Language Development-Primary and Intermediate: Fourth Edition ( Hammill & Newcomer, 2008a , 2008b ). The model allowed for linking the subtests to a general factor of language and equating their measurement characteristics across grades and cohorts of children. A sequence of models was fit to evaluate the appropriateness of the linking assumptions. Results The models fit well, with reasonable support for the validity of the tests to measure a general factor of language on a longitudinally consistent scale. Conclusion Although total and standard scores were problematic for longitudinal relations, the results of the model suggest that language grows in a relatively linear manner among these children, regardless of which set of subtests they received. Researchers and clinicians interested in longitudinal inferences are advised to design research or choose tests that can provide a developmental scaled score.

The Impact of Dialect Density on the Growth of Language and Reading in African American Children.

Purpose: The goal of the current study was to examine the impact of dialect density on the growth of oral language and reading skills in a sample of African American English (AAE)-speaking children reared in urban communities. Method: Eight hundred thirty-five African American children in first through fifth grades participated. Using an accelerated cohort design, univariate and bivariate growth models were employed to examine dialect density, oral language and reading, and the relationships between these variables. Results: For the univariate models, results indicated that (a) dialect density decreased over time by approximately 5% per year beyond first grade, (b) language skills improved approximately 0.5 SD per year, and (c) reading comprehension increased significantly from first to second grade and slowed 23% per year in second through fifth grades. Results from the bivariate models revealed that (a) dialect density and language ability are negatively associated, although dialect density did not affect change in language over time, and (b) higher dialect density is related to slower growth in reading. Conclusions: Findings from this investigation provide converging evidence for accounts in the extant literature particularly supporting a negative relationship between dialect density and oral language and between dialect density and reading while also contributing novel longitudinal evidence that suggests that changes in dialect use over time may be driven by oral language skills and that reading and dialect have a reciprocal relationship.

Measuring arithmetic: A psychometric approach to understanding formatting effects and domain specificity.

Using multitrait, multimethod data, and confirmatory factor analysis, the current study examined the effects of arithmetic item formatting and the possibility that across formats, abilities other than arithmetic may contribute to children's answers. Measurement hypotheses were guided by several leading theories of arithmetic cognition. With a sample of 1314 3rd grade students (age M=103.24 months, SD=5.41 months), Abstract Code Theory, Encoding Complex Theory, Triple Code Theory, and the Exact versus Approximate Calculations Hypothesis were evaluated, using 11 measures of arithmetic with symbolic problem formats (e.g., Arabic numeral and language-based formats) and various problem demands (e.g., requiring both exact and approximate calculations). In general, results provided support for both Triple Code Theory and Encoding Complex Theory. As predicted by Triple Code Theory, arithmetic outcomes with language formatting, Arabic numeral formatting, and estimation demands (across formats) were related but distinct from one another. As predicted by Encoding Complex Theory, executive attention was a direct predictor of all arithmetic outcomes. Language was no longer a direct predictor of arithmetic outcomes when executive attention was accounted for in the model; however, a strong and enduring relationship between language and executive attention suggested that language may play a facilitative role in reasoning during numeric processing. These findings have important implications for assessing arithmetic in educational settings and suggest that in addition to arithmetic-focused interventions, interventions targeting executive attention, language, and/or the interplay between them (i.e., internal speech during problem-solving) may be a promising avenues of mathematical problem-solving intervention.

Visual statistical learning is related to natural language ability in adults: An ERP study.

Statistical learning (SL) is believed to enable language acquisition by allowing individuals to learn regularities within linguistic input. However, neural evidence supporting a direct relationship between SL and language ability is scarce. We investigated whether there are associations between event-related potential (ERP) correlates of SL and language abilities while controlling for the general level of selective attention. Seventeen adults completed tests of visual SL, receptive vocabulary, grammatical ability, and sentence completion. Response times and ERPs showed that SL is related to receptive vocabulary and grammatical ability. ERPs indicated that the relationship between SL and grammatical ability was independent of attention while the association between SL and receptive vocabulary depended on attention. The implications of these dissociative relationships in terms of underlying mechanisms of SL and language are discussed. These results further elucidate the cognitive nature of the links between SL mechanisms and language abilities.

Testing Math or Testing Language? The Construct Validity of the KeyMath-Revised for Children With Intellectual Disability and Language Difficulties.

Although it is often assumed that mathematics ability alone predicts mathematics test performance, linguistic demands may also predict achievement. This study examined the role of language in mathematics assessment performance for children with intellectual disability (ID) at less severe levels, on the KeyMath-Revised Inventory (KM-R) with a sample of 264 children, in grades 2-5. Using confirmatory factor analysis, the hypothesis that the KM-R would demonstrate discriminant validity with measures of language abilities in a two-factor model was compared to two plausible alternative models. Results indicated that KM-R did not have discriminant validity with measures of children's language abilities and was a multidimensional test of both mathematics and language abilities for this population of test users. Implications are considered for test development, interpretation, and intervention.

Evaluating the Structure of Early English Literacy Skills in Deaf and Hard-of-Hearing Children.

Better understanding the mechanisms underlying developing literacy has promoted the development of more effective reading interventions for typically developing children. Such knowledge may facilitate effective instruction of deaf and hard-of-hearing (DHH) children. Hence, the current study examined the multivariate associations among phonological awareness, alphabetic knowledge, word reading, and vocabulary skills in DHH children who have auditory access to speech. One hundred and sixty-seven DHH children (M age = 60.43 months) were assessed with a battery of early literacy measures. Forty-six percent used at least 1 cochlear implant; 54% were fitted with hearing aids. About a fourth of the sample was acquiring both spoken English and sign. Scores on standardized tests of phonological awareness and vocabulary averaged at least 1 standard deviation (SD) below the mean of the hearing norming sample. Confirmatory factor analyses showed that DHH children's early literacy skills were best characterized by a complex 3-factor model in which phonological awareness, alphabetic knowledge, and vocabulary formed 3 separate, but highly correlated constructs, with letter-sound knowledge and word reading skills relating to both phonological awareness and alphabetic knowledge. This supports the hypothesis that early reading of DHH children with functional hearing is qualitatively similar to that of hearing children.

Reading among diverse DHH learners: what, how, and for whom?

Students whO are deaf and hard of hearing (DHH) face challenges in learning to read. Much has been written about the relative importance of the different factors associated with success in reading, but these factors are disputed within the literature on DHH readers. The Center on Literacy and Deafness, funded by the Institute of Education Sciences, is engaged in a nationwide project to identify child-by-instruction interactions related to instructional factors that are malleable within the classroom context. In the present article, the authors describe the project, present the conceptual model on which it is based, explain the processes and procedures used to choose assessment tools, and discuss their theoretical view of how reading and instruction might differ based on an individual student's language and level of functional hearing.

The Autism Impact Measure (AIM): initial development of a new tool for treatment outcome measurement.

The current study describes the development and psychometric properties of a new measure targeting sensitivity to change of core autism spectrum disorder (ASD) symptoms, the Autism Impact Measure (AIM). The AIM uses a 2-week recall period with items rated on two corresponding 5-point scales (frequency and impact). Psychometric properties were examined using a large sample (n = 440) of children with ASD enrolled in the Autism Treatment Network. The exploratory factor analysis indicated four factors and resulted in a 25-item questionnaire with excellent overall model fit. Test-retest reliability, cross-informant reliability, and convergent validity with other measures of ASD symptoms and overall functioning were strong. The AIM is a reliable and valid measure of frequency and impact of core ASD symptoms.

Classification and identification of reading and math disabilities: the special case of comorbidity.

Much of learning disabilities research relies on categorical classification frameworks that use psychometric tests and cut points to identify children with reading or math difficulties. However, there is increasing evidence that the attributes of reading and math learning disabilities are dimensional, representing correlated continua of severity. We discuss issues related to categorical and dimensional approaches to reading and math disabilities, and their comorbid associations, highlighting problems with the use of cut points and correlated assessments. Two simulations are provided in which the correlational structure of a set of cognitive and achievement data are simulated from a single population with no categorical structures. The simulations produce profiles remarkably similar to reported profile differences, suggesting that the patterns are a product of the cut point and the correlational structure of the data. If dimensional approaches better fit the attributes of learning disability, new conceptualizations and better methods to identification and intervention may emerge, especially for comorbid associations of reading and math difficulties.

Evaluation of the Technical Adequacy of Three Methods for Identifying Specific Learning Disabilities Based on Cognitive Discrepancies.

This study used simulation techniques to evaluate the technical adequacy of three methods for the identification of specific learning disabilities via patterns of strengths and weaknesses in cognitive processing. Latent and observed data were generated and the decision-making process of each method was applied to assess concordance in classification for specific learning disabilities between latent and observed levels. The results showed that all three methods had excellent specificity and negative predictive values, but low to moderate sensitivity and very low positive predictive values. Only a very small percentage of the population (1%-2%) met criteria for specific learning disabilities. In addition to substantial psychometric issues underlying these methods, general application did not improve the efficiency of the decision model, may not be cost effective because of low base rates, and may result in many children receiving instruction that is not optimally matched to their specific needs.

Assessing the reliability of Curriculum-Based Measurement: an application of Latent Growth Modeling.

The purpose of this study was to demonstrate the use of Latent Growth Modeling (LGM) as a method for estimating reliability of Curriculum-Based Measurement (CBM) progress-monitoring data. The LGM approach permits the error associated with each measure to differ at each time point, thus providing an alternative method for examining of the reliability of CBM reading aloud data over repeated measurements. The analysis revealed that the reliability of CBM data was not a fixed property of the measure, but it changed with time. The study demonstrates the need to consider reliability in new ways with respect to the use of CBM data as repeated measures.
