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

The Growth of Complex Syntax in School-Age African American Children Who Speak African American English

PURPOSE

Syntax provides critical support for both academic success and linguistic growth, yet it has not been a focus of language research in school-age African American children. This study examines complex syntax performance of African American children in second through fifth grades.

METHOD

The current study explores the syntactic performances of African American children (N = 513) in Grades 2-5 on the Test of Language Development-Intermediate who speak African American English. Multilevel modeling was used to evaluate the growth and associated changes between dialect density and syntax. Analyzed data were compared both to the normative sample and within the recruited sample.

RESULTS

The results suggest that dialect density exerted its impact early but did not continue to influence syntactic growth over time. Additionally, it was not until dialect density was accounted for in growth models that African American children's syntactic growth resembled normative expectations of a standardized language instrument.

CONCLUSION

The current study suggests that failure to consider cultural language differences obscures our understanding of African American students' linguistic competence on standardized language assessments.

Filling in the Blank: The Development of a Writing Screener for Elementary School Students Who Speak African American English

PURPOSE

Clinicians are tasked with using culturally and linguistically appropriate tools to evaluate oral and written language development accurately. However, limited tools account for linguistic diversity in writing. This gap can lead to under- and overdiagnosis of students who speak nonmainstream dialects. This study addressed that gap by developing a writing task to identify nonmainstream dialect features in the writing of early elementary school students. We describe the development, feasibility, and results of pilot testing of the task.

METHOD

One hundred fifty-one first and second graders participated in the study as part of a larger study of nonmainstream dialect use. Students completed standardized literacy and language assessments and the researcher-developed writing task. The writing task used a novel fill-in-the-blank format to identify morphological features that vary between Mainstream American English and nonmainstream varieties such as African American English.

RESULTS

Second-grade students performed better on the writing task than first graders, and writing performance was strongly related to standardized literacy scores. Literacy skills were the strongest predictor of Mainstream American English use in writing, but spoken dialect use also correlated with written dialect use.

CONCLUSIONS

The writing task captured dialect use in early elementary school students' writing, and students' performance on standardized literacy measures predicted written dialect features. These results are a first step toward developing a standardized measure to help professionals appropriately diagnose written expression disorders within linguistically diverse students.

An examination of 3rd and 5th grade students' use of dialect specific forms during a written editing task

PURPOSE

The goal of the current study was to examine the role of variety and frequency of dialectal features in relation to General American English (GAE) editing ability. This study focused on speakers of dialect-specific forms and their ability to edit to GAE. To gain insight into this relation, the following research questions were posed: (1). How do third and fifth-grade students differ in the variety of features of dialect-specific forms they use, the frequency of their use, and their editing ability to GAE? (2). Is there a significant relation between dialect use and editing ability?

METHODS

Participants included 68 third and fifth-grade students who produced at least one dialect-specific form. We measured students' ability to edit to GAE during a written editing task. Frequency and variety of dialect use were based on an oral language sample where students were asked to share their favorite game or sport.

RESULTS

Fifth-grade students are significantly better at editing written dialect specific forms to reflect GAE writing conventions as compared to third-grade students. However, there was not a significant difference in the dialect specific form usage between the two grades. Finally, there was not a significant relation between dialect specific form use and editing ability.

CONCLUSIONS

These results offer relevant clinical and educational implications for increasing cultural responsivity and promote the use of multiple measures across modalities to gain relevant information when assessing students who use dialect specific forms. Further, the results from this study provide further insights into how written editing ability exhibited through the awareness of GAE conventions improves with age despite the influence of dialect specific forms.

Exploring boundary conditions of the listening comprehension-reading comprehension discrepancy index

Conversations about the nature of dyslexia and how dyslexia impacts reading and listening comprehension get to the heart of classification and identification models of dyslexia. Recently, this conversation has been expanded to include efforts to estimate the prevalence of dyslexia in the population through the introduction of a discrepancy index of listening comprehension and reading comprehension. This discrepancy index was proposed to serve as a proxy for dyslexia when estimating its prevalence in the population. Individuals whose reading comprehension is considerably lower than their listening comprehension are thought to exhibit unexpected reading deficits. However, the index could underrepresent certain groups within the population. The current study explored this possibility using data from a sample of 4078 public-school students. We hypothesized that students from historically marginalized or otherwise disenfranchised groups (i.e., poor and minority groups) would be less likely to have a positive listening comprehension - reading comprehension (LC-RC) discrepancy index. Based on the results of multilevel linear mixed effect modeling, socioeconomic status (SES) contributed to differential performance on the discrepancy index when it was calculated using residual scores. Moreover, African American students were identified as having a reliably lower discrepancy index regardless of how it was calculated. It appears that this index, which only looks at the comprehension of language and not production, may, in fact, disadvantage students for whom oral language production differs from General American English (GAE). These outcomes suggest that this measure may lack the sensitivity to identify bidialectal students with dyslexia.
