DiscoverEcon by Gerald Nelson at the University of Illinois, Urbana-Champaign, is the most exciting and widely used Economics educational software on the market. Available both on the web and CD, this version is even more closely integrated with the McConnell/Brue text than previous versions. Students who need to explore concepts interactively will find this software especially appealing. And instructors looking for pedagogically sound, easy-to-manage, self-grading exercises for homework need look no further. The software is Java-based and includes graphing exercises, problems, and quizzes, all linked closely with the textbook. It's available for purchase in two formats: on CD or, for those who buy a pass code, as part of the Website. Call 1-800-262-4729 for ordering information.
