This paper describes the challenges of social implementation education to a special needs education school and reports a new collaboration practice to address them. We have conducted social implementation education to a nearby special needs education school for five years, in which students develop and improve digital teaching materials based on the requirements of the school’ s teachers. In this education activity, we faced three challenges in terms of social implementation education; difficulty of problem/need finding, ensuring the continuous and proper collaboration, and diffusion of development results. We took a new collaboration with a regional research community of special needs education school’ s teachers. The collaboration activities for two years made it clear that this collaboration is very useful for addressing the challenges.
