This paper specifies the content of composition instruction, some of which can be incorporated into material to be presented by and practiced on a computer. It describes instructional outcomes within the context of an instructional model of the composing situation and discusses them under the following headings: (1) the composing problem, (2) setting goals, (3) generating ideas to write about, (4) arranging the information, (5) translating (the actual writing), (6) reviewing, and (7) feedback, such as peer critiquing, teacher comment, and formal assessment. An appendix describes important instructional techniques that can aid in the implementation of composition outcomes. (Author/FL)
