The purpose of this study is to investigate the effectiveness of intensive inquiry activity through intensive camp for 2 hours and 3 days in summer vacation and 100 hours of classes from March to December 2018 by selecting 2 middle school students using OKMINDMAP for creative education. It is the result. The teacher was the assistant, and the research problem was selected by two students themselves, and the variation of the fractal dimension was investigated and the Chaos game was shown to be possible in the modified Sierpinski triangle.

This study is a result of experiment to recognize geometric and spacial conceptions for early childhood. This researcher had built up Mandala figures which was an intermediary between consciousness and unconsciousness, and then have studied about early childhood's geometric and spatial concepts by using Mandala figures. In this paper, authors have studied fractal art activities of early childhood as a follow-up study, since the structure of fractal art is similar to Mandala. As a result, three years old young children have significant correlation in four areas(figure perception, visual discrimination, position-in space perception and visual memory), but five years old young children have significant in three areas(figure perception, position-in space perception and visual memory). For five years old group, there is some difference between boys and girls, also they had described for their art activities like real models.
