David R. Hakes (University of Northern Iowa) has prepared a study guide that will enhance student success. Each chapter of the study guide includes learning objectives, a description of the chapter's context and purpose, a chapter review, key terms and definitions, advanced critical thinking questions, and helpful hints for understanding difficult concepts. Students can develop their understanding by doing the practice problems and short answer question, then assess their mastery of the key concepts with the self-test, which includes true/false and multiple choice questions.
