In Japan, most of children haven?t read children?s story (Fairy tales or tales of old Japan) because the high technology video games are more exciting than most of picture books. But they must be effective to bring up the children?s cultivation of aesthetic sensitivity. And we have heard from teachers of elementary schools that most of themes of computer education in school are the operation of Painting Tool or Game Software. To improve these problems and to aid the courses of computer-based education in elementary school, we developed new educational support tool named Cyber Theater. Cyber Theater provides the capability of easy making the 3D-CG animation of children?s story by using Script language named CTSL (Cyber Theater Scenario Language). We hope schoolteachers will be able to use Cyber Tales as teaching materials in elementary schools. We also hope that upper-aged students (including junior high school students) are able to make their original CG-animation stories as the Creative Lesson.
