Letter knowledge in parent–child conversations

This study examined code-related and oral language precursors to reading in a longitudinal study of 626 children from preschool through 4th grade. Code-related precursors, including print concepts and phonological awareness, and oral language were assessed in preschool and kindergarten. Reading accuracy and reading comprehension skills were examined in 1st through 4th grades. Results demonstrated that (a) the relationship between code-related precursors and oral language is strong during preschool; (b) there is a high degree of continuity over time of both code-related and oral language abilities; (c) during early elementary school, reading ability is predominantly determined by the level of print knowledge and phonological awareness a child brings from kindergarten; and (d) in later elementary school, reading accuracy and reading comprehension appear to be 2 separate abilities that are influenced by different sets of skills.

Although research has identified oral language, print knowledge, and phonological sensitivity as important emergent literacy skills for the development of reading, few studies have examined the relations between these aspects of emergent literacy or between these skills during preschool and during later reading. This study examined the joint and unique predictive significance of emergent literacy skills for both later emergent literacy skills and reading in two samples of preschoolers. Ninety-six children (mean age = 41 months, SD = 9.41) were followed from early to late preschool, and 97 children (mean age = 60 months, SD = 5.41) were followed from late preschool to kindergarten or first grade. Structural equation modeling revealed significant developmental continuity of these skills, particularly for letter knowledge and phonological sensitivity from late preschool to early grade school, both of which were the only unique predictors of decoding.

The relationship between the home environments of 66 children and their language and literacy development was examined. After accounting for child age, parent education, and child ability as indexed by scores on a rapid automatized naming task and Block Design of the WPPSI-R, shared book reading at home made no contribution to the prediction of the literacy skills of letter name and letter sound knowledge in kindergarten. In contrast, home activities involving letters predicted modest and statistically significant amounts of variance. For the areas of receptive vocabulary and phonological sensitivity, neither shared book reading nor letter activities were predictive. Follow-up to mid-Grade 2 underscored the importance of letter name/sound knowledge and phonological sensitivity in kindergarten in accounting for individual differences in later achievement in reading comprehension, phonological spelling, and conventional spelling.
