The research subjects consist of children with developmental delay in three inclusion classrooms, with three students respectively, in three kindergartens. Among the subjects, three children are put in two classrooms. For two other kindergartens, three children in each one kindergarten are put in one classroom. Daily schedules of the three kindergartens reflect different curriculum models respectively. Event sampling is used in this research. Through an itinerant guidance each week, one county government itinerant teacher in early childhood education, two researchers of our research, observes the initiative behaviors of children with developmental delay in inclusion classrooms. The initiative behaviors include living habits of "Joyful Self-Care Behavior" and "Respectful Behavior to Help Others," with each observation taking one hour that makes a total of 9 weeks of observation. Purpose of this research lies in comparing the differences of initiative learning behaviors for children with developmental delay in inclusive classrooms in a learning context where adult-based education and children-based curriculum model are implemented. Research findings are made available as reference for pre-school inclusive program model, teaching materials, method and evaluation. Our research indicates that children with developmental delay learning in a kindergarten where children-based curriculum model is implemented show more initiative behaviors which are more multiple by not focusing on only on a few behaviors. In an open learning environment, young children weren't kept under strict control that they have more learning opportunities every day. To enhance the initiative behaviors of children with developmental delay, we suggest the promotion of "Children-based Curriculum Model," such as the implementation of "Theme Opening Teaching Embedded in Community" recommended by researchers, with the promotional methods including teaching demo and seminar and on-site guidance.
