Originally published in 1934, this book provides the findings of psychologists which have direct bearing on the theory and practice of education, and shows the close connection between sound theory and methods of school organization and teaching. This connection is illustrated by constant application of general principles to practice, and much help is given towards the solution of the problems of the teacher, for example: learning through self-initiated constructive work; class teaching and individual study; training in social ethics; the growth of character; and the place of knowledge and craftsmanship in the curriculum.
