Abstract
This study investigated the cognitive and metacognitive aspects of writing problems in learning disabled adolescents. Twenty-one learning disabled eighth and eleventh graders constituted the target population. The comparison groups included 15 normally achieving eighth graders and a reading-age control group of 23 normally achieving sixth graders. The participants wrote two reportive essays and one argument essay, and answered a questionnaire designed to probe their metacognition about the writing process. Results indicated that normally achieving eighth graders consistently and clearly surpassed their learning disabled counterparts in both quality and quantity of essay writing. Adult judges rated normally achieving eighth graders' essays to be substantially more interesting, much clearer in communicating the goals, and to contain a substantially more felicitous word choice than those of learning disabled eighth and eleventh graders. Moreover, they wrote longer essays with much fewer spelling errors than learning disabled eighth and eleventh graders. Finally, they possessed more mature and articulate conceptions of the writing task, and were more aware of the relevance of planning and audience in writing. In striking contrast, the learning disabled eighth and eleventh graders were comparable to the normally achieving sixth graders in their performances across a broad front. This comparability occurred in the three categories of holistic ratings of essays (interestingness, clarity in communication of goals, and word choice), structural ratings of paragraphs, and metacognition about the writing process. Interestingly, learning disabled eighth and eleventh graders were superior to normally achieving sixth graders in length of essays. However, the consistent, broad picture was that the learning disabled adolescents performed at a very similar level to that of younger normally achieving children. These findings permit the conclusion that the learning disabled adolescents in this study showed a developmental delay in the cognitive and metacognitive aspects of writing.
