In Japan, several groups participated in international projects two or three years ago. These projects included HOU, Passport to Knowledge, TIE, the Bradford robotic telescope project and others. Using the Internet, it is easy to collaborate with scientists and students in other countries. We can enjoy real science in real time with a real scientist in our classroom. In this paper, I report some of our practices, and I propose establishing a good connection between each as astronomical education project using the internet and a "concerted creation class"
system to expand astronomical education.
