Online Writing Processes in Translating Cognition into Language and Transcribing Written Language by Stylus and Keyboard in Upper Elementary and Middle School Students With Persisting Dysgraphia or Dyslexia.

Participants in this study completed an on-line experiment in which they wrote essays by stylus or keyboard. Three translation measures (length of language burst, length of pauses, and rate of pausing) and four transcription measures (total words, total time, words/minute, and percent spelling errors) for composition were analyzed for two research aims. Research Aim 1 addressed whether upper elementary and middle school students with carefully diagnosed transcription disabilities (dysgraphia with impaired handwriting, n=18, or dyslexia with impaired spelling, n=20) showed significant differences from pretest to posttest, across modes of transcription (stylus or keyboard), and between diagnostic groups. Results showed significant (a) change after intervention (18 computerized lessons with learning activities in letter formation/selection, spelling, and composing) in length of pauses, total time, and words per minute; (b) mode effects (fewer words and less time by stylus; fewer pauses per minute by keyboard); and (c) interactions with diagnostic group in response to intervention on some measures. Research Aim 2 addressed whether following intervention each of the diagnostic groups performed comparably to a typical control group (n=15) in the same on-line experiment. Results showed (a) comparable performance of the dysgraphia and control groups on all keyboarding tasks but differences on two stylus measures; and (b) lack of comparable performance of the dyslexia and control groups on two stylus measures (total words and percent spelling errors) and the four keyboarding tasks related to transcription. Implications for assistive technology and writing instruction for dysgraphia and dyslexia are discussed.

Effects of transcription ability and transcription mode on translation:: Evidence from written compositions, language bursts and pauses when students in grades 4 to 9, with and without persisting dyslexia or dysgraphia, compose by pen or by keyboard.

This study explored the effects of transcription on translation products and processes of adolescent students in grades 4 to 9 with and without persisting specific language disabilities in written language (SLDs-WL). To operationalize transcription ability (handwriting and spelling) and transcription mode (by pen on digital tablet or by standard US keyboard), diagnostic groups contrasting in patterns of transcription ability were compared while composing autobiographical (personal) narratives by handwriting or by keyboarding: Typically developing students (n=15), students with dyslexia (impaired word reading and spelling, n=20), and students with dysgraphia (impaired handwriting, n=19). They were compared on seven outcomes: total words composed, total composing time, words per minute, percent of spelling errors, average length of pauses, average number of pauses per minute, and average length of language bursts. They were also compared on automaticity of transcription modes-writing the alphabet from memory by handwriting or keyboarding (they could look at keys). Mixed ANOVAs yielded main effects for diagnostic group on percent of spelling errors,, words per minute, and length of language burst. Main effects for transcription modes were found for automaticity of writing modes, total words composed, words per minute, and length of language bursts; there were no significant interactions. Regardless of mode, the dyslexia group had more spelling errors, showed a slower rate of composing, and produced shorter language bursts than the typical group. The total number of words, total time composing, words composed per minute, and pauses per minute were greater for keyboarding than handwriting, but length of language bursts was greater for handwriting. Implications of these results for conceptual models of composing and educational assessment practices are discussed.
