The next section should include what some authors term educational psychology, and others call the psychological aspects of education. In this section the first topic naturally considered is that of memory. It grows out of the biological discussion of instinct, heredity, etc. Included in the subject of memory is that of association. Following this come imagination, imitation, training of the senses, apperception, formal discipline, feeling, volition, motor training, induction, etc. Periods of mental development and the specific topics of childhood and adolescence should receive definite consideration, though more exhaustive treatment should be reserved for a distinct course in child study. The genetic point of view should be emphasized throughout.
While the number of students registered for educational psychology is not large, the numbers that are in reality pursuing this branch are increasing. Fortunately, the "psychology for teachers" and "applied psychology" of a score of years ago are giving way to a kind of educational psychology that is much more vital. Men like Judd and Thorndike are formulating a psychology of the different branches of study and of the teaching processes involved that will enable the teacher to see the connection between the psychological laws and the processes to be learned. This sort of work has been made possible by the work of Hall and his followers in studying the child and the adolescent from the standpoint of growth periods and the types of activity suited to each period. Educational psychology is therefore represented richly in principles of education, genetic psychology, mental development, child study, and adolescence, as well as in the courses labeled "Educational Psychology."
Social aspects of education
Twelve years ago courses on social phases of education were probably not offered anywhere, as they are not listed in my tabulation at that time. Today they appear in some form or other in almost every department of education. In Columbia the work is given as "Educational Sociology." The departments of sociology also emphasize various phases of educational problems. Courses on vocational education, industrial education, and vocational guidance all emphasize the same idea. The introduction of these courses means that the merely disciplinary aim of education is fast giving way to that of adjustment and utility. Educational means are (1) to enable the child to live happily and to develop normally, and (2) to furnish a kind of training which will enable him to serve society to the utmost advantage. In the courses on educational sociology, there should be an attempt to help the student feel that the highest aim of education is not individualistic, but social. The purpose is to fit the individual for coöperation, developing agencies of life that shall be mutually advantageous, for democratic society seeks the highest welfare of all its members through the coöperation and contribution of each of its members. It teaches us not only the rights and privileges of society but also its duties and obligations.
The best individual development also comes only through the social interaction of minds, and consequently various phases of social psychology must receive consideration. Various forms of coöperative effort which enlist the interest of children at various stages of development should be studied. Inasmuch as educators should link school and home, typical illustrations of the manifold means of relating the school and society should be studied, so that the teacher will not be without knowledge of their possibilities.
The child the center
Throughout the country there is evidence that the curricula in education departments have for their central object a scientific knowledge of the child, and the better adaptation of educational means to the development of the potentialities possessed by the child. This idea is evidenced by the fact that the foundation courses are psychology, principles of education, child study, educational psychology. The fact that the history of education is still so largely given as a relatively beginning course shows that the new idea has not gained complete acceptance. Many specialized courses in child study are offered, among them being such courses as the "Psychology of Childhood," "Childhood and Adolescence," "Psychopathic, Retarded, and Mentally Deficient Children," "Genetic Psychology," "The Anthropological Study of Children," "The Physical Nature of the Child." At the University of Pittsburgh a school of childhood has been established which will combine in theory and practice the best ideals in the kindergarten, the modern primary school, and the Montessori system. Clark University has had for some years its Children's Institute, which attempts to assemble the best literature on childhood and the best materials of instruction in childhood. Many of the courses in educational tests and measurements center around the study of the child.
Methods of teaching the subject
Naturally, methods of teaching the subject vary exceedingly in the different institutions. Each instructor to a large extent follows his own individual inclinations. Probably the great majority pursue the lecture method to a considerable extent. The lectures are generally accompanied by readings either from some textbook or from collateral readings.
The writer has personally pursued the combination method. For years before his own book on Principles of Education was completed the subject was presented in lecture form, and accompanied by library readings. Even now, with a textbook at hand, each new topic is outlined in an informal development lecture. Definite assignments are made from the text, and from collateral readings, which include additional texts, periodical literature, and selected chapters from various educational books. After students have had an opportunity to read copiously and to think out special problems, an attempt is made to discuss the entire topic orally. That is possible and very fruitful in classes of the right size,—not over thirty. In large classes numbering from sixty to one hundred or more, the oral discussion is not profitable unless the instructor is very skilled in conducting the discussion. The questions should never be for the purpose of merely securing answers perfectly obvious to all in the class. The questions should seek to unfold new phases of the subject. Difficult points should be considered, new contributions should be made by the students and the instructor, and all should feel that it is really an enlargement, a broadening, and a deepening of ideas gained through the lectures and the assigned readings. Very frequently individual students should be assigned special topics for report. A good deal of care must be exercised in this connection, for unless the material is a real contribution and is presented effectively, the rest of the students become wearied. If possible, the instructor should know exactly what points are to be brought out, and the approximate amount of time to be occupied.
