Construct confusion and measurement challenges have plagued emergent literacy research for decades. Using a 2 × 2 × 2 factorial design, this study evaluated the dimensionality of alphabet knowledge and identified the sequence of development of 8 alphabet knowledge skills. Eleven models were evaluated in a sample of 3,692 preschool- and elementary…

Little research has been conducted on Arabic letter knowledge. This study investigates the nature of Arabic letter knowledge, its dimensionality, and the relative difficulty of letter knowledge items, all within an item response theory (IRT) framework. Three letter knowledge tests were administered to 142 native Arabic-speaking kindergarteners…

Recent research has established that 5- to 6-year-old typically developing children in a left-right writing culture spontaneously reverse left-oriented characters (e.g., they write a [reversed J] instead of J) when they write single characters. Thus, children seem to implicitly apply a right-writing rule (RWR: see Fischer & Koch, 2016a). In…

To expand our understanding of script-general and script-specific principles in the learning of letter names, we examined how three characteristics of alphabet letters -- their frequency in printed materials, order in the alphabet, and visual similarity to other letters -- relate to children's letter-name knowledge in four languages with three…

Reading acquisition is based on a set of preliteracy skills that lay the foundation for future reading abilities. Phonological awareness--the ability to identify and manipulate the sound units of oral language--has been reported to play a central role in reading acquisition. However, current evidence is mixed with respect to its universal…

To expand our understanding of script-general and script-specific principles in the learning of letter names, we examined how three characteristics of alphabet letters -- their frequency in printed materials, order in the alphabet, and visual similarity to other letters -- relate to children's letter-name knowledge in four languages with three…

We used multidimensional item response theory to test the internal structure of the Phonological Awareness Literacy Screening in Spanish for Preschool and test for item parameter drift. The measure is aligned with the simple view of reading, which defines reading as consisting of two equally important dimensions: decoding and language…

Early childhood teachers are increasingly encouraged to support children's development of letter-sound abilities. Assessment of letter-sound knowledge is key in planning for effective instruction, yet the letter-sound knowledge assessments currently available and suitable for preschool-age children demonstrate significant limitations. The purpose…

Although there is a growing consensus that, in reading acquisition, it is essential to provide children with learning activities that promote the development of reading cognitive schemes, particularly intra-syllabic related patterns, there is no agreement on which kind of syllabic schemes should be worked out in the first place. The main aim of…
