This article describes the reasoning and structure behind the staff of the Bureau of Educational Experiments during the past few years of research and nursery school work. The demands from schools for teachers who are more capable inspired the Bureau of Educational Experiments to action and resulted in the "Bank Street School"--the colloquialism for the Cooperative School for Student Teachers. The basic philosophy of the school is that only the unafraid child has a chance in an ever-changing world! There is no standard for a status quo for institutions or materials. There are no signposts against which the fearful, aimless individual can lean for permanent support. The unafraid teacher has a rare educational gift to offer to the individual child, the group, and the social structure. One outstanding aspect of the Cooperative School work is the opportunity offered student teachers for a variety of experiences that release fears. As a result, the students glory in finding that their bodies are more capable than they suspected, and lose adult hesitations about trying new uses for their physical forces, in... dance, in carpentry, and in the finer skills of work with clay and paint.
