This paper is intended to contribute to the general literature on international teacher exchange in citizenship education. This paper was presented at the 48th Annual Conference of the Comparative and International Education Society on March 11, 2004 in Salt Lake City, Utah. (Methodology) The author reports on the content and evaluation of two parts of a year long citizenship education exchange program. The first part reviews the development, implementation, and assessment of a teacher exchange program on citizenship education held at Eastern Kentucky University for seven East Ukrainian teachers. The second part reviews and evaluates a Citizenship Education Summer Institute which the participants presented to their fellow teachers in Ukraine. (Results) Each of the activities and programs in the citizenship education seminar were evaluated by participants, mentors, and host families respectively. Data on the effectiveness of program activities, processes, and events were collected from responses to Likert scale surveys and anecdotal comments. The results are provided in attachments. The Ukrainians were generally positive about their learning experiences in the United States. Their Ukrainian colleagues found the content of what they learned in the Summer Institute very useful. (Conclusions) International teacher exchanges provide opportunities for relevant reciprocal teacher professional development, and the adaptation of "best practices" from lessons learned. (Recommendations) Continued funding of international teacher exchanges on citizenship education is needed because they mutually benefit teachers and students from both sides. (Contains 3 figures.)
