In consequence partly of the efforts of educational reformers, partly of increased interest in child-psychology, and partly of the direct experience of the schoolroom, the course of study has in the past generation undergone considerable modification. The desirabillty of starting from and with the experience and capacities of learners, a lesson enforced from all three quarters, has led to the introduction of forms of activity, in play and work, similar to those in which children and youth engage outside of school. Modern psychology has substituted for the general, ready-made faculties of older theory a complex group of instinctive and impulsive tendencies. Experience has shown that when children have a chance at physical activities which bring their natural impulses into play, going to school is a joy, management is less of a burden, and learning is easier.

Sometimes, perhaps, plays, games, and constructive occupations are resorted to only for these reasons, with emphasis upon relief from the tedium and strain of "regular" school work. There is no reason, however, for using them merely as agreeable diversions. Study of mental life has made evident the fundamental worth of native tendencies to explore, to manipulate tools and materials, to construct, to give expression to joyous emotion, etc. When exercises which are prompted by these instincts are a part of the regular school program, the whole pupil is engaged, the artificial gap between life in school and out is reduced, motives are afforded for attention to a large variety of materials and processes distinctly educative in effect, and coöperative associations which give information a social setting are provided. In short, the grounds for assigning to play and active work a definite place in the curriculum are intellectual and social, not matters of temporary expediency and momentary agreeableness. Without something of the kind, it is not possible to secure the normal estate of effective learning; namely, that knowledge-getting be an outgrowth of activities having their own end, instead of a school task. More specifically, play and work correspond, point for point, with the traits of the initial stage of knowing, which consists, as we saw in the last chapter, in learning how to do things and in acquaintance with things and processes gained in the doing. It is suggestive that among the Greeks, till the rise of conscious philosophy, the same word, τεχνή was used for art and science. Plato gave his account of knowledge on the basis of an analysis of the knowledge of cobblers, carpenters, players of musical instruments, etc., pointing out that their art (so far as it was not mere routine) involved an end, mastery of material or stuff worked upon, control of appliances, and a definite order of procedure—all of which had to be known in order that there be intelligent skill or art.

Doubtless the fact that children normally engage in play and work out of school has seemed to many educators a reason why they should concern themselves in school with things radically different. School time seemed too precious to spend in doing over again what children were sure to do any way. In some social conditions, this reason has weight. In pioneer times, for example, outside occupations gave a definite and valuable intellectual and moral training. Books and everything concerned with them were, on the other hand, rare and difficult of access; they were the only means of outlet from a narrow and crude environment. Wherever such conditions obtain, much may be said in favor of concentrating school activity upon books. The situation is very different, however, in most communities to-day. The kinds of work in which the young can engage, especially in cities, are largely anti-educational. That prevention of child labor is a social duty is evidence on this point. On the other hand, printed matter has been so cheapened and is in such universal circulation, and all the opportunities of intellectual culture have been so multiplied, that the older type of book work is far from having the force it used to possess.

But it must not be forgotten that an educational result is a by-product of play and work in most out-of-school conditions. It is incidental, not primary. Consequently the educative growth secured is more or less accidental. Much work shares in the defects of existing industrial society—defects next to fatal to right development. Play tends to reproduce and affirm the crudities, as well as the excellencies, of surrounding adult life. It is the business of the school to set up an environment in which play and work shall be conducted with reference to facilitating desirable mental and moral growth. It is not enough just to introduce plays and games, hand work and manual exercises. Everything depends upon the way in which they are employed.
