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, =18, or dyslexia with impaired spelling, =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 (=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.
本研究的参与者完成了一项在线实验,他们通过手写笔或键盘撰写文章。针对两个研究目标,分析了写作的三种翻译指标(语言爆发长度、停顿长度和停顿率)和四种转录指标(总字数、总时间、每分钟字数和拼写错误百分比)。研究目标1探讨了经过仔细诊断患有转录障碍(书写障碍伴书写受损,n = 18,或阅读障碍伴拼写受损,n = 20)的小学高年级和初中学生在预测试到后测试期间、跨转录模式(手写笔或键盘)以及诊断组之间是否存在显著差异。结果显示:(a)干预后(18节包含字母形成/选择、拼写和写作学习活动的计算机化课程)在停顿长度、总时间和每分钟字数方面有显著变化;(b)模式效应(手写笔书写的字数更少、时间更短;键盘输入每分钟停顿更少);以及(c)在某些指标上,诊断组与干预反应之间存在交互作用。研究目标2探讨了在同一在线实验中,干预后每个诊断组的表现是否与典型对照组(n = 15)相当。结果显示:(a)书写障碍组和对照组在所有键盘任务上表现相当,但在两项手写笔指标上存在差异;(b)阅读障碍组和对照组在两项手写笔指标(总字数和拼写错误百分比)以及与转录相关的四项键盘任务上表现不相当。文中讨论了对书写障碍和阅读障碍的辅助技术及写作教学的启示。
