Many states now mandate early screening for dyslexia, but vary in how they address these mandates. There is confusion about the nature of screening versus diagnostic assessments, risk versus diagnosis, concurrent versus predictive validity, and inattention to indices of classification accuracy as the basis for determining risk. To help define what…

Currently students who struggle with language and literacy learning are classified with various labels in different states--language learning disabilities, dyslexia, specific language impairment, and specific learning disability--in spite of having similar diagnostic profiles. Drawing on the research on comprehension of written language, we…

In the present study, we investigated critical factors in letter-sound acquisition (i.e., letter-name knowledge and phonological awareness) with data from 653 English-speaking kindergartners in the beginning of the year. We examined (a) the contribution of phonological awareness to facilitating letter-sound acquisition from letter names and (b)…

Comparison of 80 beginning first graders, half receiving phonics instruction and half receiving whole word instruction, found, for both groups, those above grade level in reading excelled in phonological recoding and application of grapheme-phoneme correspondence rules while those below grade level applied visual-orthographic knowledge more than…

A study involving 1,123 children investigated the relationship between naming speed and phonological awareness skills and the implications for the classification of children at risk of reading disability. Results found a positive correlation between naming speed and phonological awareness and indicate this relationship will affect any comparison…

This article reviews research on effective classroom reading instruction that finds dramatic reduction in reading failure occurs when explicit instruction is provided in phonemic awareness and decoding skills, word recognition and text processing, construction of meaning, vocabulary, spelling, and writing. The need for small-group instruction for…

Investigating how good and poor readers process words, a study examined the spelling and reading processes of 80 middle-class first grade students from three schools in Houston, Texas, 40 who were receiving whole word instruction, and 40 receiving phonics instruction. Based on scores from the Gates-McGinitie Reading Test, Basic R (administered in…

Eighty children in first grade classes differing in the amount of letter-sound instruction daily were administered tests of phonemic segmentation, reading, and spelling three times during the year. No classroom differences in phonemic segmentation were found, but classrooms with more letter-sound instruction showed more spelling and reading…
