In this experiment, we examined whether beginning readers benefit more from grapheme-phoneme decoding (GPD) than from whole-syllable decoding (WSD) instruction in learning to read and write words. Sixty Brazilian Portuguese-speaking first graders (M age = 6 years 1 month) who knew letter names but could not read or write words were randomly…

The purpose of this article is to describe recommendations for providing evidence-based literacy instruction to students with intellectual and developmental disabilities (IDD), including students with comorbid autism spectrum disorder (autism). We identify six evidence-based practices, highlight key research that supports each practice, and then…

Understanding the early literacy abilities of children who use augmentative and alternative communication (AAC) is essential for designing and testing methods of reading intervention focused on printed orthography. School-based professionals need assessments that measure word reading skills of students with heterogenous speech and physical…

Purpose: This study aimed to elucidate the nature of the relationship between the development of decoding and encoding skills in the first year at school. Method: The foundational literacy skills of one hundred eighty 5-year-old children were examined on three occasions over their first year of literacy instruction. Participants received the same…

Irregular words cannot be read correctly by decoding letters into sounds using the most common letter-sound mapping relations. They are difficult to read and learn. Cognitive models of word reading and development as well as empirical data suggest that inhibitory control might be important for irregular word reading and its development. The…

Programs for teaching English reading, especially for students with dyslexia, and educational practice standards often recommend instruction on dividing polysyllabic words into syllables. Syllable division is effort intensive and could inhibit fluency when reading in text. The division strategies might still be useful if they work so consistently…

The accompanying article introduces highly transparent grapheme-phoneme relationships embodied within a Periodic table of decoding cells, which arguably presents the quintessential transparent decoding elements. The study then folds these cells into one highly transparent but simply stated singularity generalization--this generalization unifies…

Since 2012, when preparatory grade (PG) became compulsory in Romania for 6-year olds, little understanding has been gained of how children's literacy evolves in PG, although over the same period, Romanian 15-year olds' reading performance has shown no signs of improvement (Noveanu et al., 2023). Children enter school with broadly varying literacy…

Learning to read English is more difficult than in most other alphabetic languages. It sometimes seems there are not reliable rules for linking letters with sounds. Teaching students all of the letter patterns they may find in texts is no simple task. Students struggle processing the sounds in words, so even words with simple spellings are…

Background: Despite evidence that synthetic phonics teaching has increased reading attainments, a sizable minority of children struggle to acquire phonics skills and teachers lack clear principles for deciding what types of "additional" support are most beneficial. Synthetic phonics teaches children to read using a decoding strategy to…

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…

The importance of letter sound knowledge (LSK) as a precursor to later literacy skills has been well-documented. Since English language learners (ELLs), or students who first acquired a language other than English, continue to underperform in reading compared to their English-speaking peers, they are particularly at-risk for reading and academic…

Two methods of decoding instruction were compared. Participants were kindergartners who knew letter sounds but could not decode nonwords, M = 5.6 years. The segmented phonation treatment taught students to convert graphemes to phonemes by breaking the speech stream ("sss -- aaa -- nnn") before blending. The connected phonation treatment…

This study explored the effects of instruction in letter sound correspondence (LSC) with four preschool students with disabilities. The study included participants with developmental delay, autism spectrum disorder, and communication disorders. Researchers incorporated nonverbal methods of response to accommodate study participants with…

Central questions in the study of visual word recognition and developmental dyslexia are whether early lexical activation precedes and supports decoding (a dual-stage view) or not (dual-route view), and the locus of deficits in dysfluent reading. The dual-route view predicts early word frequency and length interaction, whereas the dual-stage view…
