Building upon the strength and success of deBlij & Muller's best-selling "Geography: Realms, Regions, and Concepts, Tenth Edition", "Concepts and Regions" offers students and instructors all of the content that has made "Regions" the definitive World Regional Geography text but in a briefer, technologically rich package. At about one-half the length of most world regional texts, the text offers brief regional descriptions, applications of core concepts, and definitions to acquaint students with the spatial interconnections between the human and physical systems of the earth. The accompanying interactive CD-ROM serves two key functions. First, the CD contains all of the content from "Realms, Regions, and Concepts 10/e", allowing students and instructors to delve deeper into the subject matter found in the text. Second, the CD features the GeoDiscoveries Present-Interact-Assess framework which enables students to animate and interact with maps, view videos, and test themselves, providing them instant assessment feedback on key concepts. GeoDiscoveries for "Concepts" features an interactive globe, multiple-choice questions, drag-and-drop map exercises, key term matching exercises, flashcards, demonstrations of concepts and geographic techniques, critical thinking exercises, interactive animations, and more. GeoDiscoveries is designed to be used both by students for understanding and assessment of key concepts, as well as by instructors for in-class presentations. The third component of the "Concepts" learning system is its website, which features interactive testing, links to geographic organizations and interactive exercises that illustrate key concepts in action. Many weblinks come from region-specific sites, allowing students to listen to live radio broadcasts or to view real-time images from a region.
