The aim of this research is to determine if a Buddhist meditation program, formed with consideration of th e developmental stage and interests of school-age children, is effective in increasing the self regulation of sch ool-age children. The subjects of study were elementary school students from grade 3 to grade 6 who partici pated in Sunday Buddhist service held in Y Buddhist temple in Yeongdo-gu, Busan. A total of 28 people we re studied, 14 people were classified and organized into the treatm ent group, and 14 people into the contro l group. The Buddhist meditation activity program was applied to the 14 people in th e treatment group wit h parental consent, and the original program run by the Sunday school was applied to the 14 people in the control group, and to investigate the average of the two groups, pre-test and post-test concerning the self reg ulation were run. The research tool used in this research was an instrument for measuring the self regulation for school-age children, and used a self regulation rating scale developed from ‘Research on school-age childr en’s self regulation rating scale develop ment and related variables’ (JeongKyung Heo, 2004). This measuring instrument was formed with the basis of the theory of study and social situation in the process of decisionmaking of the child of Miller (2000). This rating scale consists of a total of 27 questions in the three sub-fac tors, the cognitive (11 questions), motivational (8 questions), and behavioral (8questions)factor. Also, a survey for school parents was used. With the data analysis of the results from the self regulation test, the collected data were analyzed by using SPSS/PC for Windows 12.0.To check whether or not the Buddhist meditation a ctivity program had increased the self regulation, a paired samples t-test for the pre-test and the post-test we re run, and to determine the effect of running the experiment, a new variable was produced by subtracting t he pre-test result from the post-test result, and an independent sample t-test was run by using that variable. The results of the research are as follows. First, the Buddhist meditation program, formed with consideration of the developmental stage and interests of school-age children, was shown to have a positive effect at incr easing the self regulation of school-age children. In particular, out of the sub factors of self regulation of the treatment group, the cognitive factor’s knowledge, data and sign interpretation and the behavioral factor's e motion and impulsiveness factor showed a statistically meaningful increase after the Buddhist meditation pro gram particip ation. Second, after viewing the children’s reactions during the Buddhist meditation program, it was seen that as the meditat ion time increased, the concentration, confidence, looking at other people’s feel ings, etc also increased. Because this is related to the cognitive factor’s memory, the motivational factor’s trust towards ability and the behavioral factor’s emotion, which are all sub factors of self regulation, it is seen a s an effect from the increase in self regulation. Third, after viewing the children’s reflection and reactions 여 ring the Buddhist meditation program,it could be seen that there were effects on positive physical changes(b ack straight, breathing calm, etc) and emotional changes (feeling relieved, less irritations). This research has m eaning in that it contributes to positively changing the self regulation by allowing the school-age children to l ook at themse lves thoroughly and to control their emotions and actions, by calming their restless mind and making them comfortable, by using the Buddhist meditation program, formed with consideration of the devel opmental stage and interests of them, using the above research results as a foundation.
