This book is offered as a practical help to teachers, supervisors, principals, and superintendents in the improvement of the elementary school curriculum. An underlying theme is the possibility of organizing a curriculum upon the basis of the activities of life in which children engage, as opposed to subjects in which few are engaged. This book is an intermediate step from the wasteful, unsatisfactory organization currently in place toward a more desirable method. It presents a pragmatic pedagogy, with definite aims, direct methods, and appreciable results. The relationships of purpose, content, and method place a high premium upon effort, and immediate, individual and cooperative activity under the guidance of social ideals.
