This book studies the basic principles underlying sound and progressive pedagogy. In its scope and organization it aims to give (1) a comprehensive and systematic analysis of the principles of education, (2) the modern trend and interpretation of educational thought, (3) a transition from pure psychology to methods of teaching and discipline, and (4) practical applications of educational theory to the problems that confront the teacher in the course of daily routine. Every practical pedagogical solution that is offered has actually stood the test of classroom demonstration. The book opens with a study of the function of education and a contrast of the modern social conception with those aims which have been guiding ideals in previous educational systems. Part II deals with the physiological aspects of education. Part III is taken up with the problem of socializing the child through the curriculum and the school discipline. The last part of the book, Part IV, The Mental Aspect of Education, is developed under the following sections: _Section A._ The Instinctive Aspect of Mind. Mind and its development through self-expression. Self-activity. Instincts. _Section B._ Intellectual Aspect of Mind. The functions of Intellect, Perception, Apperception, Memory, Imagination, Thought Activities. The Doctrine of Formal Discipline and its influence upon educational endeavor. _Section C._ Emotional Aspect of Mind. _Section D._ Volitional Aspect of Mind. Study of will, kinds of volitional action, habit vs. deliberative consciousness. The Education of the Will. Education and Social Responsibility, the problems of ethical instruction, and the social functions of the School. In order to increase the usefulness of the book to teachers of education there is added a classified bibliography for systematic, intensive reference reading and a list of suggested problems suitable for advanced work.
