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…

Learning to read is one of the most important components of education and literacy skills in early childhood have a significant impact on later reading success. There is an abundance of quantitative research focused on reading, known as the science of reading. However, gaps and flaws have been identified in the research, indicating that an…

The need for effective reading instruction is of high priority. One of the many ways that students learn to read is through multisensory instruction. Elementary-age students struggle to become proficient readers. This is due to the lack of reading skills. The goal of reading is comprehension. As students learn letter-sound correspondence,…

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…

Background: Failure to learn early reading skills leads to lower reading comprehension later in elementary school (Double et al., 2019; Paige et al., 2019), which can then lead to poverty, underemployment, and increased likelihood of being incarcerated (World Literacy Foundation, 2018). Early reading skills are best developed in kindergarten…

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…
