This report describes Huntington simulations--computer programs and associated off-line materials for the teacher and for the students. Separate guidelines for choosing a simulation are presented for the curriculum planner and for the teacher. The Huntington simulation, POLUT, is the example which is used. Modifications to this program and its materials are described, and a role-playing game is outlined that will initiate consideration by the students of the value orientations that affect decisions about environmental issues.
