Critical Thinking, Thoughtful Writing begins with the premise that thinking well involves using language well, and vice versa. This rhetoric with readings--written by critical-thinking scholar John Chaffee and English professors Christine McMahon and Barbara Stout--provides thorough coverage of the writing process, going beyond the traditional rhetoric to teach students how to evaluate sources, images, and arguments. Each chapter focuses on a critical-thinking skill--such as problem solving or analysis of complex issues--that is explored through Thinking-Writing Activities and thematically linked readings. The text helps students develop these skills through carefully sequenced pedagogy and a cross-disciplinary approach that asks them to complete writing assignments and critically evaluate readings drawn from a variety of disciplines. The Fourth Edition features an enhanced discussion of plagiarism with critical-thinking exercises, as well as a special focus on using and documenting Internet sources appropriately.
