Relations Among Children's Use of Dialect and Literacy Skills

The current meta-analysis examines recent empirical research studies that have investigated relations among dialect use and the development and achievement of reading, spelling, and writing skills. Studies published between 1998 and 2014 were selected if they: (a) included participants who were in Grades K-6 and were typically developing native English speakers, (b) examined a concurrent quantitative relationship between dialect use and literacy, including reading, spelling, or writing measures, and (c) contained sufficient information to calculate effect size estimates. Upon the removal of one study that was found to be an outlier, the full sample included 19 studies consisting of 1,947 participants, of which the majority (70%) were African American. The results showed a negative and moderate relationship between dialect use and overall literacy performance (M effect size = -0.33) and for dialect and reading (M effect size = -0.32). For spelling and writing, the relationship was negative and small (M effect size = -0.22). Moderator analyses revealed that socioeconomic status and grade level were not significant predictors for relations among dialect use and literacy skills. Implications for practice and future research, including analyzing dialect use in a variety of contexts and examining these relations to literacy outcomes, are discussed.
