Approaches to the effective use of foreign students as educational resources within the elementary or secondary school classroom to increase international understanding among Americans are addressed. Brief descriptions are presented of programs that infuse an international dimension into all aspects of the curriculum. The following long-term, schoolwide activities are covered: (1) a school of international studies, (2) a center for international studies/magnet programs, (3) multilingual/multicultural programs, (4) peer tutoring programs, (5) intercultural and international communication courses, (6) global education, (7) community discovery projects, and (8) international student exchange programs. Short-term, schoolwide activities or classroom activities are also considered as follows: student/classroom sharing, field trips/community exploration, written exercises, folklore/customs, language, and current events/political issues. Sources of assistance in developing activities are listed, along with publications dealing with administrative issues, and organizations publishing these types of materials. General information about evaluation in the cross-cultural learning process is also presented. Finally, an index that is helpful in identifying activities and resources most appropriate for specific grade levels and subjects is included. Entries in the index are cross-referenced by grade levels and subject (English, fine arts, foreign languages, home economics, math and science, physical education, and social studies). (SW)
