ABSTRACT
No book on educational psychology can deal with the many practical problems which confront classroom teachers and school administrators. The best that can be done is to present certain fundamental explanatory principles of broad application and to describe certain methods by which the situations that arise in schools from time to time can be analyzed. The discovery of the psychological causes which are operative in particular cases must be left to those who are in contact with these cases. Above all, the best method of dealing with each situation that comes up must be left to the judgment of the teacher or school administrator. Science can help to prepare the practical school officer for wise action, but it cannot lay down prescriptions that make unnecessary the exercise of independent intelligence in the handling of cases.
