EDUCATIONAL PSYCHOLOGY
By Professor EDWARD THOMDIKE
In this book Professor Thorndike applies to a num- ber of social, and especially educational problems, the methods of exact science. The topics are treated in the light of the most recent researches and with the aid of modern statistical technique. The book thus provides those interested in education as a profession or as a feature of American life with a sample of scientific method in this special field as well as with important information which has hitherto been inac- cessible. The attitude of the author, who is the head of the department of educational psychology in Teach- ers College, Columbia University, and the author of numerous original contributions to dynamic psychol- ogy, is that of a candid and painstaking student of the work that has been done in this field and upholds rigoreus ideals of scientific accuracy and logic. The book is so written and illustrated as to be readable and teachable.
