Purpose: Research on how much early phonemic awareness (PA) instruction is optimal has produced inconclusive answers. We conducted a nonlinear meta-analysis to estimate the optimal cumulative dosage of early PA instruction on PA outcomes with an associated maximum effect size in preschool through first-grade students. Method: Sixteen experimental…

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…

Deficits in reading fluency and in spelling can dissociate during development, resulting in groups with reading deficit only (RD), spelling deficit only (SD) and combined reading and spelling deficit (RSD). The current study investigated the one-to-two-year longitudinal stability of these subgroups in 167 German-speaking children. Reading fluency…

Purpose: This study was designed to assess the efficiency of a French version of "GraphoGame" (GG) against an equally engaging math intervention ("Fiete Math," FM) in a large school sample of children from socioeconomically disadvantaged neighborhoods in grade 1 (N = 921). Method: The intervention was implemented in two…

The overlapping waves model put forth by Robert Siegler emphasizes variability, adaptive choice, and gradual change in children's problem solving. These concepts were applied to emergent reading of an alphabet book with pages of three difficulty levels. Ninety-one kindergartners completed tests of emergent literacy. Twice, about 12 weeks apart,…

In a quasiregular orthography like English, children inevitably encounter irregular words during reading. Previous research suggests successful reading of an irregular word depends at least partially on a child's ability to address the mismatch between decoded form and stored word pronunciation, referred to as a child's set for variability, and…

It is now widely accepted that phonological language skills are a critical foundation for learning to read (decode). This longitudinal study investigated the predictive relationship between a range of key phonological language skills and early reading development in a sample of 191 children in their first year at school. The study also explored…

Spelling is influenced by implicit cues, but less is known about variability in this reliance. We assessed whether the influence of three implicit cues on Dutch past tense spelling was moderated by grade, literacy, and format. An Auditory infinitive, Written infinitive, and Picture+cloze format was completed by 68 third-graders and 47…

The automatic letter-sound integration hypothesis proposes that the decoding difficulties seen in dyslexia arise from a specific deficit in establishing automatic letter-sound associations. We report the findings of 2 studies in which we used a priming task to assess automatic letter-sound integration. In Study 1, children between 5 and 7 years of…

We examined whether global instruction of complex akshara and explicit phoneme-level instruction of akshara impact the development of phoneme awareness and its association with akshara knowledge and word reading accuracy. The participants were 100 Sinhala-speaking children from Grades 4 and 5 in Sri Lanka. Phoneme awareness showed stronger growth…

The present study investigated the moderating role of orthographic consistency on the development of reading comprehension in four language groups (English, n = 179; Spanish, n = 188; Czech, n = 135; Slovak, n = 194) from kindergarten to Grade 2. In all languages, early variations in phoneme awareness/letter knowledge, rapid automatised naming,…

In the present study, the mediating roles of syllable awareness, orthographic knowledge, and vocabulary skills and the moderating role of morpheme family size in the association between morphological awareness and Chinese character reading were investigated with 176 second-grade Hong Kong Chinese children. In the path analyses, the results…

We evaluated the impact of teaching complex grapheme-phoneme correspondences (GPC) derived from the Simplicity Principle to at-risk poor readers in Grade 2 classrooms, using a two-arm dual site matched control trial intervention. Poor word readers (n = 149) were allocated to either a) Simplicity GPC (n= 79) or b) Letter-Name Control (n= 70) small…

Orthographic mapping (OM) involves the formation of letter-sound connections to bond the spellings, pronunciations, and meanings of specific words in memory. It explains how children learn to read words by sight, to spell words from memory, and to acquire vocabulary words from print. This development is portrayed by Ehri (2005a) as a sequence of…

The present study examined the construct and predictive validity of a dynamic test of decoding. In theory, a dynamic test provides a direct measure of potential for learning. In this study, children were taught 3 novel letters and how to blend the sounds of those into new words, then they were tested on different words comprising the 3 letters.…
