本研究目的在探討幼兒在參與動手作科學活動歷程其心流經驗（flow experience）改變的類型，及不同心流經驗變化類型在個人及家庭環境變項上的差異。研究參與者包含308位幼稚園學生。由於研究者在潛在成長趨勢模式（latent growth curve model, 簡稱LGM）的分析結果中，發現整體幼兒的心流經驗雖呈現顯著的直線成長趨勢，不過起始狀態與成長率之間呈現負相關，再者，在以不同個人、家庭環境變項進行多階層LGM分析結果，發現這些變項對幼兒心流經驗起始狀態有顯著的預測力，但在成長率的預測力卻不顯著，為了能更深入瞭解幼兒在參與動手作科學活動的心流經驗變化及影響因素，故以二階段集群分析將幼兒心流經驗的變化進行分群，再透過卡方考驗、單因子多變量變異數分析進行統計考驗。研究結果顯示：

The purpose of this study was to explore the categories of preschool children’s flow experience in hands-on sciences activities and the relationships among flow experience categories, family environment, and playfulness of preschool children. 308 young children sampled participated in this study. The employed instruments in this study were the Preschool Children’s Science Flow Experience Scale, the Questionnaire of Family Environment, the Children’s Playfulness Scale. The employed analysis methods included Two Step Cluster Analysis, Chi-Square Test and One-Way Multiple Analysis of Variance. The results have shown：
