The "Decroly plan" lays ground rules for social adaptation of a biological organism, in the concrete case, children. It concludes that schooling is needed for children to meet their "biosocial needs". Followers of Decroly have gone on to create and start schools that primarily focus on these "biosocial needs", and better augment the student's educational experience. These visionary teachers include such people as Fanneal Harrison and Catherine Gavin, who have founded prestigious schools such as Out-of-Door Academy.
To educate in its fullest sense is to create conditions in which the child can live - and is led by these conditions led to live-as fully as possible through each succeeding stage of his development, meeting and solving in his own experience the problems of each stage as it comes, and so gaining the power to meet and to solve the problems that await him in further stages. Such conditions it is for a school to provide. (Decroly cited by J.H. Badley, Dr. Ovide Decroly ed. Albert Decordier, Amicale Rijksbasisonderwijs, Ronse, Belgium)
