Although phonics knowledge and decoding skill are important for academic and life success, there is little research that examines the effects of home-based, family-implemented instruction on the development of these early literacy skills. The purpose of this multiple baseline across participants single case experimental design study was to…

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…

Fluency with skills that operate below the word level (i.e., sublexical), such as phonemic awareness and alphabetic knowledge, may ease the acquisition of decoding skills (Ritchey & Speece, 2006). Measures of sublexical fluency such as phoneme segmentation fluency (PSF), letter naming fluency (LNF), and letter sound fluency (LSF) are widely…

This study of children from two U. S. states examined associations among four cognitive and academic skills: executive function (EF), visuo-motor integration, mathematics assessed with applied problems, and letter-word knowledge. Before (T1) and after (T2) kindergarten, children (N=555) were assessed using the Head-Toes-Knees-Shoulders (HTKS) EF…

Despite the poor outcomes for U.S. students on national writing tests, overall research on how to teach writing is sparse, and this scarcity is more pronounced in the early years of beginning to write. In this study 81,200 we present preliminary findings from Year 1 of a 3-year Institute of Education Sciences-funded Goal 2 project aimed at…

In this thesis, I present three related papers that collectively investigate the instructional supports on screen and in the media viewing context that influenced English and heritage language vocabulary knowledge in DLLs. In study 1, I examine how specific pedagogical approaches used in educational media might benefit DLLs. In study 2, I…

The goal of the current study was to determine whether Concept of Word in Text (COW-T) predicts later sight word reading achievement in Spanish, as it does in English. COW-T requires that children have beginning sound awareness, automatic recognition of letters and letter sounds, and the ability to coordinate these skills to finger point…

We investigated the latent factor structure of the "Phonological Awareness Literacy Screening for Kindergarteners" in Spanish ("PALS español K"). Participants included 590 Spanish-speaking, public-school kindergarteners from five states. Three theoretically-guided factor structures were measured and tested with one half of our…
