This report describes the rationale, implementation, and results of an experimental ninth-grade composition program in which students from three classes worked through activities that use different media to help them communicate effectively in narration, exposition, and critical analysis. Sentence combining was included as a part of the program. A control group of ninth graders from another school completed the assessment measures but did not participate in the experimental program. Writing skills were assessed with pretests, midtests, and posttests; students' and teachers' changes in attitude were measured; and subjective evaluations of the program were obtained from teachers and students. Analyses indicated that the writing of students in the experimental group gained more than that of those in the control group in interest, conflict, character depiction, word choice, sentence structure, overall quality, and fluency, but not in average length of T-unit or in reduction of usage errors. Appendixes provide a detailed description of the curriculum, assessment instruments, and transcripts of teachers' and students' reactions to the program. (AA)
