Spelling errors in the Wide Range Achievement Test were analyzed for 77 pairs of children, each of which included one older child with spelling disability (SD) and one spelling-level-matched younger child with normal spelling ability from the Colorado Learning Disabilities Research Center database. Spelling error analysis consisted of a percent…

Writing is a multifaceted, complex task that involves interaction between physical and cognitive skills. Individuals with physical disabilities vary in terms of both their physical and cognitive abilities. Often they must overcome one or more significant barriers in order to engage in the task of writing. Minimizing or eliminating barriers is…

We present an inference algorithm for perturbation models based on Poisson regression. The algorithm is designed to handle unclassified input with multiple errors described by independent mal-rules. This knowledge representation provides an intelligent tutoring system with local and global information about a student, such as error classification…

Theoretical perspectives on spelling characterize development as a progression through qualitatively different phases or as a process of more or less continuous growth. This study investigated the potential utility of a different perspective, the overlapping-wave model, for characterizing spelling development (Rittle-Johnson & Siegler, 1999). In…

36 Saudi EFL freshmen students took a listening-spelling test in which they filled out 100 blanks in a dialogue. Results indicated that 63% of the spelling errors were phonological and 37% were orthographic. It was also found that the subjects had more phonological problems with whole words but more orthographic problems with graphemes. Some of…

This paper examines some of the problems faced by deaf children when attempting to spell the words of written English. It analyses deaf children's awareness of English spelling patterns and considers whether there are spelling errors which are common to these children. Twenty-two children with varying degrees of hearing level were involved and…

Learning to spell on the computer may lead to functionally useful writing skills. Alan and Suzy, teenagers with developmental disabilities, were already proficient on a variety of naming and matching tasks but had difficulties spelling; Suzy also made errors reading orally. In Experiment 1, computer teaching led to new anagram and written spelling…

Spelling error analysis performed on 27 dyslexic fourth to eighth graders and 27 normal second graders revealed no significant differences in phonetic accuracy, level of maturity, or incidence of serial order confusion. Findings did not support prevailing approaches characterizing dyslexic students as phonetically inaccurate spellers. (CL)

Describes system design proposed by the Spelling Error Detection Correction Project (SPEEDCOP) at Chemical Abstracts Service. Highlights include principles of detection/correction system; spelling error detection (the dictionary, suffix normalization, bypassing specialized word classes, document-level frequency threshold); spelling error…

Background: Studies focusing on reading errors can help to understand how children learn to read and to structure key components of reading instruction. However, no prior studies have examined which letters might be a greater source of difficulty for beginning readers in Spanish. Aims: First, to examine the pattern of reading errors in beginning…

The Spelling Error Detection Correction Project completed at Chemical Abstracts Service, which extracted over 50,000 misspellings from approximately 25,000,000 words of scientific and scholarly text, shows that expected incidence of misspelling is 0.2 percent, and most misspellings are "typos," 90 percent of which are unlikely to be…

An important element of learning to read and write at school is the ability to define word boundaries. Defining word boundaries in text writing is not a straightforward task even for children who have mastered graphophonemic correspondences. In children's writing, unconventional word segmentation has been observed across a range of languages and…

Results of analysis of 1,377 spelling error forms including three categories of spelling errors (consonantal, vowel, and sequential) demonstrate that majority of spelling errors are highly predictable when set of predefined rules based on phonological and sequential considerations are followed algorithmically. Eleven references and equivalent…

Investigates the differences in spelling error features among learning disabled and normal students across four grade levels of spelling achievement. Finds support for the theory of developmental word knowledge and for the position that learning disabled and normally achieving children acquire aspects of orthography in similar progressions. (RS)
