The purpose of this study was to investigate the impact of Motor Skills Program on preschool children's fundamental motor skills, cognition of movement concept and the correlation of fundamental motor skills, cognition of movement concept. The participants in this study were the Preschool Children of two classes in preschool of elementary school. One was Taipei Municipal Xing Ya Elementary School, and the other one was Taipei City Nankang District Yu Cheng Elementary Schoolin this study. Before and after the intervention of six weeks Motor Skills Program, children completed Fundamental Motor Skills and Cognition of Movement Concept in pretest and posttest. In order to investigate data in this study, the Fundamental Motor Skill Test(Chou,2004; Kovar, Combs & Campbell,2004) and the Assessment of Cognition Movement concept(Huang, 2003; Schiemer,2000) were used in this study. Finally, using the Statistic Analyzing method, Independent t-test, Paired sampling t-test, and Pearson's Product Moment Correlation in this study. There were results: 1.After six weeks Motor Skills Program, the Experiment group had significantly improved in Motor Skills and Cognition of Movement Concept. 2.With compared the pretest and posttest of Experiment Group and Control Group, Experiment Group had significantly better than Control Group in Fundamental Motor Skills; but had no significant in Cognition of Movement Concept. 3. After six weeks Motor Skills Program, the Experiment Group had significantly correlation between Fundamental Motor Skills and Cognition of Movement Concept; but the Control Group had no significantly correlation between Fundamental Motor Skills and Cognition of Movement Concept. Therefore, through educate motor skills will improve the ability of cognition learning, apprehension, application. And, through meaningful motor skills experience will change the cognition learning behavior forever. About learning motor skills, preschool children need an appropriate learning environment, induction and frequently exercise opportunity to develop, expert, fiddly all motor skills; not only with the maturational factor (Hsu, 2001;Gallahe, 1997). In conclusion, it is suggested in this study that gradually amplification the research in the future, and build up a criterion-referenced standard for the preschool students' motor skills educators to take it for educate and assessment standard.Keyword(s): curriculum development, early childhood, physical activity
