Writing Across the Curriculum in Middle and High Schools lays the foundation of writing instruction with an explanation of the writing process, including classroom examples implemented throughout the curriculum. The levels of writing provide a common-sense way to approach evaluation and at the same time offer practice for writing. Writing is so much more than the usual term paper, and this book explains a multitude of ways to incorporate writing into the curriculum. A variety of instructional methods are described, including portfolios. The book includes examples of students' writing and teachers' planning, and interdisciplinary units illustrate how to combine areas to more closely mirror real-life situations. This text presents writing as a tool for learning information, understanding concepts, and retaining knowledge. It is through writing that instructors can encourage students to become active learners, and this text helps instructors facilitate that goal.
