Amazon.com description: Product Description: An extensive student guide has been developed for this edition. Because students learn in different ways, the guide includes a variety of pedagogical aids to help them truly master the material. Each chapter is outlined and summarized, major terms and figures are defined, and self-tests are provided. Learning Objectives, Chapter Outlines, Chapter Summaries, and Key Terms reflect the new content in the Sixth Edition. A full 30 percent of the questions in the Self-Test section have been revised. Each question in the Self-Test section tests students on one of the Learning Objectives in the text, and the Learning Objective with which each question correlates is cited in the Answer Key.
