Linguistic Contributions to Word-Level Spelling Accuracy in Elementary School Children With and Without Specific Language Impairment

Speech-Language Pathologist Reading Survey: Scope of Practice, Training, Caseloads, and Confidence

PURPOSE

The purpose of this study was to examine speech-language pathologists' (SLPs) opinions on their scope of practice related to reading, self-reported background training, current caseloads, and confidence in their abilities to define, assess, and provide effective treatment for reading-related difficulties.

METHOD

SLPs (N = 271) from across the United States completed an online survey assessing their opinions on scope of practice, education and training in reading, and confidence in defining, assessing, and treating reading-related difficulties.

RESULTS

A majority of respondents agreed that the identification, assessment, prevention, and intervention of reading disabilities are all within the scope of practice of SLPs. However, a majority also reported that literacy instruction is more heavily the responsibility of teachers than SLPs, and approximately half felt similarly regarding prevention, assessment, identification, and intervention of reading disabilities. Many respondents did not feel that their training in reading was adequate and felt that more graduate coursework should be dedicated to literacy. There was a lot of variability in responses when asked how often respondents focus on reading skills with clients, ranging from almost daily to never; however, results indicate that SLPs rarely administer reading assessments. Overall, respondents were more confident in their ability to define versus assess or provide therapy for various reading subskills.

CONCLUSION

Despite SLPs agreeing that reading is within their scope of practice and feeling confident in some aspects of reading, graduate programs for speech-language pathology may need to provide greater training in literacy, especially related to reading assessment and diagnosis.

A systematic review of the academic achievement of primary and secondary school-aged students with developmental language disorder

Background and aims

The ability to communicate is a fundamental skill required to participate in school. Students with Developmental Language Disorder (DLD) have persistent and significant language difficulties that impact daily functioning. However, the impact of DLD on the academic achievement of primary and secondary school-aged students has received limited attention.

Methods

A systematic review of the empirical research published between 2008 and 2020 was undertaken to identify studies that have examined the academic achievement of school-aged students with DLD within curriculum areas. A total of 44 studies were identified that met inclusion criteria for review.

Results

Students with DLD demonstrated difficulties with academic achievement across all measured curriculum areas compared to their typically developing peers. Most studies focused on literacy skills, including reading, spelling, writing and narratives.

Conclusions and implications

The performance of students with DLD was heterogeneous with individual students demonstrating relative strengths in some areas of academic achievement. The implications of these results for educational practices and future research are discussed.

Diagnosis of Developmental Language Disorder in Research Studies

Purpose The aim of this study was to investigate the extent to which researchers in the field of developmental language disorder are utilizing validated methods to diagnose their research participants. Method We examined 90 research articles published from 2015 to 2019 that included English-speaking participants from the United States who were identified as having a developmental language disorder or specific language impairment. From these articles, we identified the tests and measures used to identify participants and classify them as healthy or impaired. We then consulted the test manuals and the literature to find information on sensitivity and specificity of the test and the evidence-based cut score that maximized identification accuracy. Results Of the 90 articles examined, 38 (42%) were found to reflect validated diagnostic methods, and 51 (58%) did not. Conclusion Our results illustrate that validated methods are used less than half of the time even by those who should have a high level of expertise and despite calls for increasing scientific rigor in research practices.

Derivational Morphology Bridges Phonology and Orthography: Insights Into the Development of Word-Specific Spellings by Superior, Average, and Poor Spellers

Purpose Morphology, which is a bridge between phonology and orthography, plays an important role in the development of word-specific spellings. This study, which employed longitudinal sampling of typically developing students in Grades 3, 4, and 5, explored how the misspellings of words with derivational suffixes shed light on the interplay of phonological, orthographic, and morphological (POM) linguistic features as students learn to integrate POM features appropriately to generate correct spellings. Method Sixty typically developing Grade 3 students were tested using the Spelling subtest from the Wechsler Individual Achievement Test-Second Edition (Wechsler, 2001) and were divided into superior, average, and poor spellers. Students' spelling skill was then assessed using the Wechsler Individual Achievement Test-Second Edition annually for another 2 years. Misspelled derivations from these three testing sessions were analyzed for linguistic feature errors and error complexity/severity. Differences in the integration of POM features across spelling ability levels at Grades 3-5 were analyzed with Kruskal-Wallis analyses of variance. Results Longitudinal results demonstrated POM integration for the development of word-specific spellings involving derivational morphology was in its initial stages over Grades 3-5 and was influenced by spelling ability level. Information from a qualitative analysis revealed considerable variability in how students applied their POM knowledge to spell complex derivations. Conclusions Word-specific spellings draw on multiple linguistic codes-P, O, and M-and their interconnections. It involves more than an understanding of orthographic rules. Rather, accurate spelling develops through an increased understanding of the phoneme-grapheme relationships as facilitated by the identification of word parts (base + or - affixes) in written language. Educational and clinical implications are discussed.

Morphological Awareness Skills of Second- and Third-Grade Students With and Without Speech Sound Disorders

Purpose Morphological awareness is the ability to consciously manipulate the smallest units of meaning in language. Morphological awareness contributes to success with literacy skills for children with typical language and those with language impairment. However, little research has focused on the morphological awareness skills of children with speech sound disorders (SSD), who may be at risk for literacy impairments. No researcher has examined the morphological awareness skills of children with SSD and compared their skills to children with typical speech using tasks representing a comprehensive definition of morphological awareness, which was the main purpose of this study. Method Thirty second- and third-grade students with SSD and 30 with typical speech skills, matched on age and receptive vocabulary, completed four morphological awareness tasks and measures of receptive vocabulary, real-word reading, pseudoword reading, and word-level spelling. Results Results indicated there was no difference between the morphological awareness skills of students with and without SSD. Although morphological awareness was moderately to strongly related to the students' literacy skills, performance on the morphological awareness tasks contributed little to no additional variance to the children's real-word reading and spelling skills beyond what was accounted for by pseudoword reading. Conclusions Findings suggest that early elementary-age students with SSD may not present with concomitant morphological awareness difficulties and that the morphological awareness skills of these students may not play a unique role in their word-level literacy skills. Limitations and suggestions for future research on the morphological awareness skills of children with SSD are discussed.

The Relation Between Linguistic Awareness Skills and Spelling in Adults: A Comparison Among Scoring Procedures

Purpose Spelling is a skill that relies on an individual's linguistic awareness, the ability to overtly manipulate language. The ability to accurately spell is important for academic and career success into adulthood. The spelling skills of adults have received some attention in the literature, but there is limited information regarding which approach for analyzing adults' spelling is optimal for guiding instruction or intervention for those who struggle. Thus, we aimed to examine the concurrent validity of four different scoring methods for measuring adults' spellings (a dichotomous scoring method and three continuous methods) and to determine whether adults' linguistic awareness skills differentially predict spelling outcomes based on the scoring method employed. Method Sixty undergraduate college students who were determined to be average readers as measured by a word reading and contextual word reading task were administered a spelling task as well as morphological, orthographic, phonemic, and syntactic awareness tasks. Results All four scoring methods were highly correlated suggesting high concurrent validity among the measures. Two linguistic awareness skills, morphological awareness and syntactic awareness, predicted spelling performance on both the dichotomous and continuous scoring methods. Contrastively, phonemic awareness and orthographic awareness predicted spelling performance only when spelling was scored using a continuous measure error analysis. Conclusions The results of this study confirm that multiple linguistic awareness skills are important for spelling in adults who are average readers. The results also highlight the need for using continuous measures of spelling when planning intervention or instruction, particularly in the areas of orthographic and phonemic awareness.
