The aim of this course for grades 10-12 is to develop in students their command of language through their use of it. It tries to guide the student through the actual process of composition, avoiding the treatment of the pre-writing stage and the writer's situation. The instruction material is divided into six categories (Conciseness and Clarity, Diction, Sentence Construction, Unity, Amplification, and Coherence) which are developed in the three grades through 33 teaching units. Each unit states the specific rhetorical principle under consideration; presents a bibliography and procedures for teaching the concept, often indicating how texts, duplicated material, and other resources may be utilized; and concludes with literature-correlated assignments, student writing samples, and comments on the samples. All of the units are practical examples of methods, materials, and assignments tested in the classroom and proved viable. (lh)
