This study was a research and development (R&D) that adapts Borg and Gall development model, using 5 out of 10 main steps of the development research, i.e. the survey and information gathering, planning, developing initial product formats, initial testing, and revision of the initial product. The product feasibility test was carried out by two validators, i.e. the material validator and the media validator. The initial test was carried out on one teacher and six children in Pertiwi Kindergarten I Sawahan. Data were collected through validation sheets, teacher response questionnaires, interview guides, and observations. Data were analyzed for the effectiveness using the Wilcoxon signed ranks test with a significance level of 0.05. The results show that: (1) to increase the collaboration ability of children aged 5-6 years, the Team-Assisted Individualization learning model is appropriate to stimulate the children; (2) the developed guide book was categorized “very feasible” viewed from the material and the media; and (3) the developed Team-Assisted Individualization learning model was proven to be effective in stimulating children’s collaboration abilities with a significance level (p)<0.05; this means that there is a significant change in the ability of children to collaborate before and after the treatment.
