The purpose of this project was to develop and disseminate interdisciplinary instructional materials that focus on human beings and their impact on nine environmentally important areas within the continental United States. Drafts of the instructional modules and mini-modules were prepared by interdisciplinary teams participating in two summer workshops. Many of these modules, focusing on the Mojave Desert and the Northern Sierra Nevada, were completed by instructional design experts and sent to faculty members at one or more community colleges for peer review. Completed sets of materials will be sent to 48 individual colleges involved in the project. Further dissemination will take place through invitational workshops for other community colleges within the region. (Author/CO)
