The present short paper reports on the 8th overseas teaching practicum in the United States by 13 graduate students of Hiroshima University, Japan, partly organized by Hiroshima University Global Partnership School Center (GPSC) since 2006. The participating students were those majoring in elementary/secondary school education and they observed and also conducted lessons in English in six local public/private schools in North Carolina. The aim of this project was threefold: 1) to self-develop practical instructional competence by teaching pupils with different cultural backgrounds; 2) to enhance the abilities in developing teaching materials through hands-on teaching experiences in English; and 3) to acquire the abilities to design, implement and evaluate programs for promoting global partnership. Furthermore, the school project was followed by cross-cultural field study visits to NC State Capitol, Raleigh and the U.S. Capitol, Washington, D.C. Among the major achievements through this project was enhanced global awareness and classroom communication skills of the future teachers. It is hoped that this short but intensive experience in diverse school settings will broaden the Japanese students’ personal horizons and confidence in teaching.
