In the 20th century with rapid scientific development, lifestyles of people changed. Living styles became more diverse and feelings and methods of expression on beauty were also broadened. Recent works are so diverse and complicated that they cannot be understood by the limited definition of art in the past. In order to assist children of 21st century in expressing their feelings using new and modern artistic language, it is necessary to approach art using the concept of formative activities instead of limiting it to activities like drawing and making. Teachers are now showing positive view on computers by accepting this change and agreeing that computer education is necessary and effective. Child education institutions are performing activities related to computers. However, the ratio of actual institutions that are operating computer-based education for children is less than half of all child education institutions. Such institutions are experiencing various difficulties resulting from lack of computer knowledge in teachers and unification of educational activities. From this perspective, the purpose of this study is to connect the topics of the internet and environment in teaching of children and to examine the unified topic of 'environment' through a case study on formative activities. In particular, by allowing children to have direct education experience on the future asset called environment, the author attempts to maximize the effect of ICT education through positive and enthusiastic learning behavior accomplished by formative and computer activities.
