In this dissertation I report findings from two studies of the literacy abilities of children with Williams syndrome (WS), a genetic disorder associated with intellectual disability. I had two overarching goals: 1) evaluate the applicability of theories of reading and spelling acquisition developed based on typically developing children to…

Background: Research acknowledges the importance of phonological processing and orthographic processing for reading and spelling in both consistently and inconsistently written languages. While the focus has tended to be on the role of phonological processing in languages with consistent orthographies, the role of orthographic processing,…

The purpose of the present study was to examine the effects of a brief experimental intervention that integrated spelling practice into a systematic phonics approach to initial reading instruction for at-risk children. The effects of this intervention were studied by means of a randomized controlled trial design that compared the experimental…

Docklands Primary School opened its doors in Melbourne in January 2021. In this case study, Emina McLean, Head of English, describes how Sounds-Write was implemented in Foundation to Year 2 in the middle of the pandemic. Despite four lockdowns forcing periods of online teaching, various standardised tests show 80% of students on average meeting or…

A brief experiment was designed to examine cognitive flexibility practice embedded in beginning phonics instruction for kindergarteners with limited early literacy learning. Previously tested phonics content included single- and high-frequency two-letter grapheme-phoneme correspondences (GPCs), introduced at a rate of 2-4 correspondences per week.…

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…

A large-scale, cluster-randomized controlled field trial (N[subscript classrooms] = 47; N[subscript students] = 1,013) assessed the impact of a digital text-to-speech reading material that supported 8-year-olds' decoding and reading comprehension. An active control group used the most prevalent Danish learning material with a research-based…

Background: The purpose of this study was to examine the effects of Structured Word Inquiry (SWI; an orthography intervention with a focus on morphology and how morphology interrelates with phonology and etymology) and Simplicity intervention (a novel phonics intervention) on the reading and spelling skills of persistently poor Grade 3 readers.…

A nonrandomized quasi-experimental, mixed-method double pretest-posttest design was used to compare the effects of a multilinguistic word study model of instruction -- RAVE-O program (Wolf, Miller, & Donnelly, 2000) -- in comparison with a phonics word study model of instruction -- Fountas and Pinnell Phonics Lessons -- Letters, words, and how…

An important characteristic of expert teaching is the ability to adapt instruction to meet learners' needs. One way this type of ownership of instruction happens is through teachers interactively constructing knowledge about pedagogical content with others. In this article, the authors looked at how a group of thirteen participants enrolled in an…

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…

In this case study, Angela Helsloot, Principal at Allambie Heights Public School, on the Northern Beaches of Sydney, uses data from standardised tests and benchmark reading assessments across the school to show the positive impact that Sounds-Write instruction has had in Kindergarten and Year 1. [For the complete volume, "Systematic Synthetic…

There is some evidence that reading and spelling are complementary processes. The purpose of this study was to investigate the extent to which contextualized spelling (i.e., spelling activities within the context of reading instruction) is used to support reading in first-grade core reading programs. Analysis of 75 lessons across five programs…

The purpose of this study was to examine the effects of Build a Word-Easy Spelling with Phonics, an electronic application of the word box intervention, on the acquisition, maintenance, and generalization of letter-sound correspondences for Learners of English as an Additional Language (LEALs). A single-subject multiple probe experimental design…

The development of beginning decoding and encoding skills is influenced by linguistic skills as well as executive functions (EFs). These higher-level cognitive processes include working memory, inhibition, and cognitive flexibility, and individual differences in these EFs have been shown to contribute to early academic learning. The present study…
