Abstract
Research evidence is reviewed to show (a) that transcription and working memory processes constrain the development of composition skills in students with and without learning disabilities; and (b) that in turn other processes constrain the development of transcription and working memory skills. The view of working memory as a resource-limited process is contrasted with a view of working memory as a resource-coordination process that integrates transcription and constructive processes, which may be on different time scales, in real time. Theory-driven, research-validated interventions for transcription are discussed with a focus on how training transcription transfers to improved composition. Five theoretical explanations for why the spelling component of transcription is more difficult to learn than the word recognition component of reviewing are also considered with a focus on the instructional implications of each for improving spelling. Finally, a rationale is presented for directing writing instruction to the simultaneous goals of (a) automaticity of low-level transcription and (b) high-level construction or meaning for purposeful communication.
