Despite being a critical emergent literacy skill and an indicator of risk for later reading difficulties, relatively little is known about how alphabet knowledge develops over time. This study utilized a person-centered approach and longitudinal sample of 998 preschool-aged children (M = 56.50 months old) to examine patterns in letter name and…

Educators' language and literacy knowledge is considered important for informing classroom practices and thereby supporting children's early language and literacy development. This includes both disciplinary content knowledge (knowledge concerning how oral and written language are structured and map to one another) and knowledge for practice…

In the present study, we examined patterns of code-focused emergent literacy skill growth for children from lower and higher socioeconomic (SES) families enrolled at a high-quality early childhood center. Measures of letter name knowledge, letter sound knowledge, alliteration, and rhyming were collected at three time points over the course of the…

Early childhood teachers are increasingly encouraged to support children's development of letter-sound abilities. Assessment of letter-sound knowledge is key in planning for effective instruction, yet the letter-sound knowledge assessments currently available and suitable for preschool-age children demonstrate significant limitations. The purpose…

Early childhood educators are increasingly asked to support the alphabet knowledge development of children enrolled in their classrooms. Children in the same classroom, however, often show vastly different alphabet learning needs. Moreover, recent research suggests that some letters are more difficult to learn. These facts run counter to…

Preschool-age children (N = 58) were randomly assigned to receive instruction in letter names and sounds, letter sounds only, or numbers (control). Multilevel modeling was used to examine letter name and sound learning as a function of instructional condition and characteristics of both letters and children. Specifically, learning was examined in…

Review of current federal and state standards indicates little consensus or empirical justification regarding appropriate goals, often referred to as benchmarks, for preschool letter-name learning. The present study investigated the diagnostic efficiency of various letter-naming benchmarks using a longitudinal database of 371 children who attended…

Preschool-aged children (n = 58) were randomly assigned to receive small group instruction in letter names and/or sounds or numbers (treated control). Alphabet instruction followed one of two approaches currently utilized in early childhood classrooms: combined letter name and sound instruction or letter sound only instruction. Thirty-four 15…

Alphabet knowledge is a hallmark of early literacy and facilitating its development has become a primary objective of preschool instruction and intervention. However, little agreement exists about how to promote the development of alphabet knowledge effectively. A meta-analysis of the effects of instruction on alphabet outcomes demonstrated that…
