An award-winning fourth-grade unit combines computer and economics education by examining the impact of computer usage on various segments of the economy. Students spent one semester becoming familiar with a classroom computer and gaining a general understanding of basic economic concepts through class discussion, field trips, and bulletin boards. The 18-week unit then tied these economic concepts to computer usage as follows. Students examined: computers as suppliers of wants and needs and as solutions to labor problems (scarcity); computer technology's effect on the standard of living (economic goals); computers as capital goods (productive resources); the creation of a market for computers (market economy); financial uses of computers (financial institutions); computer related careers (circulation flow); increases in productivity through computers (resource extenders); the contribution of others to computer availability (economic interdependence); and deciding on computer use (decisionmaking). As a culminating activity, students developed an "economics quotient" test which was programmed for the computer and offered as part of an open house program. A program evaluation and bibliography are included. (LP)
