PROCESS OF ANALYSIS
Knowledge Obtained Through Use of Ideas.—As already noted, the presented problem of a lesson is neither a state of complete knowledge nor a state of complete ignorance. On the other hand, its function is to provide a starting-point and guide for the calling up of a number of suitable ideas which the pupil may later relate into a single experience, constituting the new knowledge. Take, for example, a person without a knowledge of fractions, who approaches for the first time the problem of sharing as found in such a question as:
Divide $15 between John and William, giving John $3 as often as William gets $2.
In gaining control of this situation, the pupil must select the ideas $3 and $2, the knowledge that $3 and $2 = $5, and the further knowledge that $15 contains $5 three times. These various ideas will constitute data for organizing the new experience of $9 for John and $6 for William. In the same manner, when the student in grammar is first presented with the problem of interpreting the grammatical value of the word driving in the sentence, "The boy driving the horse is very noisy," he is compelled to apply to its interpretation the ideas noun, adjectival relation, and adjective, and also the ideas object, objective relation, and verb. In this way the child secures the mental elements which he may organize into the new experience, or knowledge (participle), and thus gain control of the presented word.
Interpreting Ideas Already Known.—It is to be noticed at the outset that all ideas selected to aid in the solution of the lesson problem have their origin in certain past experiences which have a bearing on the subject in hand. When presented with a strange object (guava), a person fixes his attention upon it, and thereupon is able, through his former sensation experiences, to interpret it as an unknown thing. He then begins to select, out of his experiences of former objects, ideas that bear upon the thing before him. By focusing thereon certain ideas with which he is perfectly familiar, as rind, flesh, seed, etc., he interprets the strange thing as a kind of fruit. In the same way, when the student is first presented in school with an example of the infinitive, he brings to bear upon the vague presentation various ideas already contained within his experience through his previous study of the noun and the verb. To the extent also to which he possesses and is able to recall these necessary old ideas, will he be able to adjust himself to the new and unfamiliar presented example (infinitive). It is evident, therefore, that a new presentation can have a meaning for us only as it is related to something in our past experience.
Further Examples.—The mind invariably tries to interpret new presentations in terms of old ideas. A newspaper account of a railway wreck will be intelligible to us only through the revival and reconstruction of those past experiences that are similar to the elements described in the account. The grief, disappointment, or excitement of another will be appreciated only as we have experienced similar feelings in the past. New ideas are interpreted by means of related old ideas; new feelings and acts are dependent upon and made possible by related old feelings and acts. Moreover, the meaning assigned to common objects varies with different persons and even with the same person under different circumstances. A forest would be regarded by the savage as a place to hide from the attacks of his enemies; by the hunter as a place to secure game; by the woodcutter as affording firewood; by the lumberman as yielding logs for lumber; by the naturalist as offering opportunity for observing insects and animals; by the artist as a place presenting beautiful combinations of colours. This ability of the mind to retain and use its former knowledge in meeting and interpreting new experiences is known in psychology as apperception. A more detailed study of apperception as a mental process will be made in [Chapter XXVI].
THE SELECTING PROCESS
Learner's Mind Active.—A further principle of method to be deduced from the foregoing is, that the process of bringing ideas out of former experiences to bear upon a presented problem must take place within the mind of the learner himself. The new knowledge being an experience organized from elements selected out of former experiences, it follows that the learner will possess the new knowledge only in so far as he has himself gone through the process of selecting the necessary interpreting ideas out of his own former knowledge and finally organizing them into new knowledge. This need for the pupil to direct mental effort, or attention, upon the problem in order to bring upon it, out of his former knowledge, the ideas relative to the solution of the question before him, is one of the most important laws of method. From the standpoint of the teacher, this law demands that he so direct the process of learning that the pupil will clearly call up in consciousness the selected interpreting ideas as portions of his old knowledge, and further feel a connection between these and the new problem before him.
Learner's Experience Analysed.—The second stage of the learning process is found to involve also a breaking up of former experience. This appears in the fact that the various ideas which are necessary to interpret the new problem are to be selected out of larger complexes of past experience. For example, in a lesson whose problem is to account for the lack of rainfall in the Sahara desert, the pupil may have a complex of experiences regarding the position of the desert. Out of this mass of experience he must, however, select the one feature—its position in relation to the equator. In the same way, he may have a whole body of experience regarding the winds of Africa. This body must, however, be analysed, and the attention fixed upon the North-east trade-wind. Again, he may know many things about these winds, but here he selects out the single item of their coming from a land source. Again, from the complex of old knowledge which he possesses regarding the land area from which the wind blows, he must analyse out its temperature, and compare it with that of the areas toward which the wind is blowing. Thus it will be seen that, step by step, the special items of old knowledge to be used in the apperceptive process are selected out of larger masses of experience. For this reason this phase of the learning process is frequently designated as a process of analysis.
Problem as Object of Analysis.—Although the second step of the learning process has been described as a selecting of elements from past experience, it might be supposed that the various elements which the mind has been said to select from its former experiences to interpret the new problem, come in a sense from the presentation itself. Thus it is often said, in describing the present step in the learning process, that the presentation embodies a certain aggregate of experience, which the learner can master by analysing it into its component parts and recombining the analysed parts into a better known whole.
