Structured Literacy (SL) approaches are often recommended for students with dyslexia and other poor decoders (e.g., International Dyslexia Association, 2017). Examples of SL approaches include the Wilson Reading System (Wilson, 1988), Orton-Gillingham (Gillingham & Stillman, 2014), the Lindamood Phoneme Sequencing Program (Lindamood &…

Quantifying the decoding difficulty (i.e., 'decodability') of text is important for accurately matching young readers to appropriate text and scaffolding reading development. Since no easily accessible, quantitative, word-level metric of decodability exists, we developed a decoding measure (DM) that can be calculated via a web-based scoring…

Spelling error corpora can be collected from students' written essays, homework, dictations, translations, tests and lecture notes. Spelling errors can be classified into whole word errors, faulty graphemes and faulty phonemes in which graphemes are deleted, added, reversed or substituted. They can be used for identifying phonological and…

A descriptive study of vowel spelling errors made by children first diagnosed with dyslexia (n = 79) revealed that phonological errors, such as "bet" for "bat", outnumbered orthographic errors, such as "bate" for "bait". These errors were more frequent in nonwords than words, suggesting that lexical context helps with vowel spelling. In a second…

This study provides detailed descriptions of the reading impairments in four 10-year-old Norwegian children with dyslexia. In all four cases reading comprehension was well in advance of the children's slow and inaccurate word-recognition skills. Phonological decoding (as assessed by pseudohomophone and nonword reading) appeared relatively…

Good and poor readers, 15- and 16-year-olds and adult literacy students, were compared in their ability to produce graphemic representations for four specific phonemes. Good readers were significantly better than poor readers at representing the critical phonemes, but intentional ambiguity had a similar effect on all. (MSE)
