Compares deaf writers to basic writers with normal hearing in terms of their apparent attention to grammatical correctness. Finds that deaf subjects devoted substantially less attention to grammatical decision making during composition. (MS)

Identifies a particular class of explanatory discourse, and proposes hypotheses about the types of knowledge likely to be associated with skill in this genre. Finds that variations in accuracy and adaptiveness of students' explanations were partially accounted for by measures of topic knowledge, social cognition, and discourse knowledge. (MG)

Examines the opposition of objectified exposition and personal narrative posited by rhetorical tradition and maintained by most composition texts and syllabi today.

Outlines two hypotheses about the reasons for obscurity in expository writing and notes that neither accounts for the general results of an exploratory study of the writing of postgraduates nor for the individual cases presented. Argues that a crucial factor is a person's implicit model of expository writing. (FL)

Examines the effects of various writing tasks (notetaking, answering study questions, and essay writing) on learning, using recall of specific text elements and recall of the theme or gist of expository writing. Finds that students' topic knowledge, passage content structure, and the nature of the task influence students' text comprehension. (MM)
