One of a series of guides to the teaching of writing at the elementary and secondary levels, this publication focuses on teaching writing through models that introduce ideas, patterns, and styles through specific examples. The major portion of the publication describes learning activities, grouped into seven categories according to purpose: stimulating interest for writing; developing standards for writing; showing the relationship among writer, subject, and audience; showing main ideas and supportive evidence; showing idea order and connection; showing how precise observation leads to clear, concise wording; and showing how to draw conclusions and make judgments. Within each category, activities are further subdivided according to four age levels: kindergarten through grade three, grades four through six, middle school, and high school. Other sections of the publication suggest writing models for content areas other than English, present a brief overview of research on using models to teach writing, and provide lists of sources of activities for different grade levels, stories for young children that teach mathematical concepts, "repeater" books in which sentence patterns are repeated, and recommended readings to aid in the understanding of models.
