Two experiments explored rates for introducing grapheme-phoneme correspondences (GPCs) and the types of correspondences taught for optimal alphabet and early literacy skills learning. In both studies, children entered with minimal alphabet knowledge and were randomly assigned within classrooms to one of two treatments delivered individually over…

We examined the efficacy of 20 weeks of individual supplemental phonics-based instruction for language minority (LM) and non-LM first graders. Students were designated LM if the primary home language was not English (otherwise non-LM). Those performing in the bottom half of their classroom LM/non-LM group in letter knowledge and phonological…

The current study follows a sample of lower skilled language minority (LM) and native English-speaking (non-LM) students who participated in an efficacy trial of a kindergarten phonics-based intervention. Follow-up procedures allowed 93% of the original sample to be retained for simple treatment effects modeling (N = 78 LM and N = 59 non-LM) and…

At-risk 1st graders were randomly assigned to tutoring in more or less decodable texts, and instruction in the same phonics program. The more decodable group (n = 39) read storybooks that were consistent with the phonics program. The less decodable group (n = 40) read storybooks written without phonetic control. During the first 30 lessons,…
