This study conducted in the Samsung Children' s Museum investigated as follows. First, whether or not the popularity of art exhibits differ according to the type of exhibit(participatory versus non-participatory) and the characteristics of exhibit. Second was to find out whether or not the perception of art exhibits differ according to the age of children and the characteristics of participatory exhibit. Third was observed whether or not the children interacted with the exhibits in compliance with the objectives that were originally set out for each exhibit. And last was finding out that the time spent at each type of participatory exhibit and the number of participatory exhibit chosen differ according to the age of children. Subjects were 160, 5- 12 year olds children, and they were divided into three age groups(a preschool group of 5- 6 year olds, a lower elementary group of 7 - 9 year old, and a higher elementary group of 10-12 year olds). A tirning and tracking observation checklist was used to document the time spent at each participatory and non-participatory exhibit. The results of the study are as follows. First, the popularity of participatory exhibits differed from the non-participatory exhibits. Overall, 10 Participatory exhibits excluding one had remarkably high popularity comparing with 4 non-participatory exhibits which had low attractiveness and holding power. Also, the popularity of participatory exhibits differed according to the characteristics of each exhibits. 55 percent of those had both high attractiveness and holding power, so they were the most popular. Closely looking at the characteristics, we can find the activities like spinning a handle for perceptual discrirnination, sliding four puzzle pieces, tuming pages, scratching, and putting pieces into the hole for feeding. These activities were the exhibits not only for perceptual discrirnination, but also for needing other small muscle activities. Second, the perception of art exhibits varied according to the characteristics of participatory exhibits.o Two exhibits which showed 100 percent of perceiving frequency needed the perception of exhibit for interacting with participatory exhibit more. Average frequency of perceiving artworks was 73.8 percent, and was statically higher than frequency of not perceiving. Furthermore, after observing the perception of artworks according to childreno s age, the elementary kids perceived the relationship between the participatory exhibit and the artwork more. Third, 94.4 percent of children interacted with the participatory exhibits in compliance with the objectives that were originally set out for each exhibit. Like the exhibition of this study, if we related the artwork and the participatory exhibit more, the participatory exhibits were used as the purpose of the exhibit more comparing with formal research. Fourth, by researching the difference between the time spent and the number of participatory exhibits chosen according to the age of children, there was no difference in the number of participatory exhibits chosen, but in the time spent. Therefore, preschoolers interacted with participatory exhibits the longest, then, a lower elementary group, and finally, a higher elementary group.
