This fourth report in the National University Continuing Education Association (NUCEA) Challenges for Continuing Higher Education Leadership series draws attention to the wider and more complex set of issues surrounding the "internationalization" of U.S. society and its educational componets. The report consists of papers prsented at a NUCEA-sponsored forum, including: "International Understanding and Economic Development: New Challenges for Continuing Higher Education Leadership" (Schuh); "Response: Continuing Education Research and Development" (Miller); "On Teaching Language and Culture in America" (Lombardi); "Response: The Federal Role--Pure versus Applied Learning" (Gunderson); "Immigration and Hispanic Educational Opportunity: Challenges for the 1990s" (Tienda); "Response: Strategies for Continuing Higher Education--Improving Educational Opportunities for Minorities" (Kohl); "Fostering Knowledge Exchange in an Interdependent World" (Walshok); "The Continuing Educator as Broker" (Burnett); "Citizen Education for an Interdependent World" (Baumann); "The Public and Public Policy" (Yanofsky); "The Canadian/U.S. Free Trade Agreement: Implications for Continuing Education" (Orris); and "National Associations" (Pankowski). The report is supplemented by descriptions of nine model programs (ongoing initiatives sponsored by continuing higher education departments around the country that address international education needs in particularly interesting and effective ways). Readers are urged to consider whether these or similar programmatic responses would work in the own campus environments. (NLL)
