This text combines content and practical activities, called 'Check Your Understanding, ' that provide a hands-on, applied approach to preparing for the actual assessment of students. You will benefit from completing all of the activities as you proceed through each chapter. The exercises at the end of each chapter will help you review chapter content and will provide a foundation for understanding the concepts presented in subsequent chapters. The answers for ""Check Your Understanding' activities and the exercises are provided in the Instructors Manual. Key terms are listed at the beginning of each chapter; each is defined in a marginal note at the appropriate point in the text. Many of the key terms are reintroduced throughout the text as they are used in the context of individual chapters.
