This paper reports on the overseas teaching practicum in the U.S. and the international forum in which we exchanged ideas on “next-generation global teacher education.” This year, four graduate school students participated in the overseas teaching practicum, and we found the change of their lessons from “information-giving” style in the previous years to “experiencing”, “exchanging”, and “creating” type of lessons this year. The participants reported that it became an excellent opportunity for them to consider a better and comprehensible way to explain something to children since there was “the English barrier”, they noticed the power of visual and other means to convey messages. In the international forum, held earlier in July in Hiroshima, two participants of the previous year’s overseas teaching practicum program reported how their perspectives toward education and the actual lessons had been changed from the experience. The speakers from the U.S. introduced how international exchange at their schools work to broaden the students’ eyes and their global-mind.
