The purpose of his study was to explore the effect of crossover musical activities applying the
traditional Korean Jang-dan on the multicultural perception of young children. The subjects of this
study were one class of 21 5-year-old children(experimental group) in J kindergarten and two
classes of 5-year-old children (20 children in comparative group and 20 children in control group) in
S kindergarten located in Y city, totaling 61 children (31 male children and 30 female children).
Twenty sessions of Crossover musical activities applying the traditional Korean Jang-dan (rhythmic
patterns) developed by the author were applied to the experimental group, musical activities focusing
on traditional Korean music to the comparative group and musical classes from Nuri curriculum for
5-year-olds to the control group, respectively. The result of this study showed the following, among
the sub-factors of multi-cultural perception, the scores of post-cultural openness and post-cultural
acceptability showed a significantly higher level in statistical terms in the experimental group, for
which crossover musical activities applying the traditional Korean Jang-dan were conducted, than
those in the comparative group and the control group. The comparative group which participated in
musical activities of traditional Korean music exhibited a significantly higher level of post-cultural
respectfulness statistically (than other groups). The result of this study implies that crossover
musical activities applying the traditional Korean Jang-dan have the effect of enhancing the
perception of cultural openness and cultural acceptability which are the sub-factors of young
children's multi-cultural perception.
