We discuss how to achieve an ICT system for linking several classrooms. The concluded important points for developing the system should have functions of (1) promoting much higher activity than in a single classroom, (2) stimulating discussion between a teacher and students or among students in different classrooms, and (3) not requiring a cost at the beginning and for maintenance. The completed system consists of a single server with a scheduling functions and a function of parent-child-grandchild devices supporting a direct discussion between a teacher and students or among students in different classrooms.
