CHAPTER XII

APPLICATION OF KNOWLEDGE

OR

LAW OF EXPRESSION

Practical Significance of Knowledge.—In our consideration of the fourth phase of the learning process, or the law of expression, it is necessary at the outset to recall what has already been noted regarding the correlation of knowledge and action. In this connection it was learned that knowledge arises naturally as man faces a difficulty, or problem, and that it finds significance and value in so far as it enables him to meet the practical and theoretical difficulties with which he may be confronted. In other words, man is primarily a doer, and knowledge is intended to guide the conduct of the individual along certain recognized lines. This being the case, while instruction aims to control the process by which the child is to acquire valuable social experience, or knowledge, it is equally important that it should promote skill by correlating that knowledge with expression, or should strive to influence action while forming character. To apperceive, for instance, the rules of government and agreement in grammar will have a very limited value if the student is not able to give expression to these in his own conversation. It becomes imperative, therefore, that as far as possible, expression should enter as a factor in the learning process.

Examples of Expression.—Man's expressive acts are found, however, to differ greatly in their form. When one is hurt, he distorts his face and cries aloud; when he hears a good speech he claps his hands and shouts approval; when he reads an amusing story he laughs; when he learns of the death of a friend he sheds tears; when he is affronted his face grows red, his muscles tense, and he strikes a blow or breaks into a torrent of words; when he has seen a striking incident he tells some one about it or writes an account to a distant friend. When his feelings are stirred by a patriotic address, he springs to his feet and sings, "God Save the King." The desire that his team should carry the foot-ball to the southern goal causes the spectator to lean and push in that direction. When he conceives how he may launch a successful venture, the business man at once proceeds to carry it into effect. These are all examples of expression. Every impression, idea, or thought, tends sooner or later to work itself out in some form of motor expression.

TYPES OF ACTION

A. Uncontrolled Actions.—Passing to an examination of such physical, or motor, activities, we find that man's expressive acts fall into three somewhat distinct classes. A young child is found to engage in many movements which seem destitute of any conscious direction. Some of these movements, such as breathing, sneezing, winking, etc., are found to be useful to the child, and imply what might be termed inherited control of conduct, though they do not give expression to any consciously organized knowledge, or experience. At other times, his bodily movements seem to be mere random, or impulsive, actions. These latter actions at times arise in a spontaneous way as a result of native bodily vigour, as, for instance, stretching, kicking, etc., as seen in a baby. At other times these uncontrolled acts have their origin in the various impressions which the child is receiving from his surroundings, or environment, as when the babe impulsively grasps the object coming in contact with his hand. Although, moreover, these instinctive movements may come in time under conscious control, such actions do not in themselves imply conscious control or give expression to organized knowledge.

B. Actions Subject to Intelligent Control.—To a second class of actions belong the orderly movements which are both produced and directed by consciousness. When, in distinction to the movements referred to above, a child pries open the lid to see what is in the box, or waves his hand to gain the attention of a companion, a conscious aim, or intention, produces the act, and conscious effort sustains it until the aim is reached. The distinction between mere impulsive and instinctive actions on the one hand, and guided effort on the other, will be considered more fully in [Chapter XXX].

C. Habitual Actions.—Thirdly, as has been noted in [Chapter II], both consciously directed and uncontrolled action may, by repetition, become so fixed that it practically ceases to be directed by consciousness, or becomes habitual.
