Family-kindergarten cooperation plays a significant role in early childhood social-emotional learning. However, existing research still faces shortcomings in terms of unclear collaboration pathways and the lack of operational feasibility in intervention strategies. This study utilizes the Behavior Change Wheel (BCW) model, focusing on three core elements—capability, opportunity, and motivation of collaborative behaviors—to design intervention strategies such as education, training, environmental restructuring, incentives, modeling, and enablement. To ensure the effective implementation of these strategies, this study also proposes four types of policy supports: guidelines, financial measures, service provision, and environmental planning. Theoretically, this study extends the application of the BCW in the educational field, demonstrating its applicability in cross-stakeholder collaboration. Practically, this study provides educators with new pathways to optimize family-kindergarten cooperation, aiming to enhance the effectiveness of early childhood social-emotional learning.
