all opportunity for first-hand acquaintance with real things; hence they appealed to sense-perception to fill the gap. It is not surprising that this enthusiastic zeal failed frequently to ask how and why observation is educative, and hence fell into the error of making observation an end in itself and was satisfied with any kind of material under any kind of conditions. Such isolation of observation is still manifested in the statement that this faculty develops first, then that of memory and imagination, and finally the faculty of thought. From this point of view, observation is regarded as furnishing crude masses of raw material, to which, later on, reflective processes may be applied. Our previous pages should have made obvious the fallacy of this point of view by bringing out the fact that simple concrete thinking attends all our intercourse with things which is not on a purely physical level.
The sympathetic motive in extending acquaintance
I. All persons have a natural desire—akin to curiosity—for a widening of their range of acquaintance with persons and things. The sign in art galleries that forbids the carrying of canes and umbrellas is obvious testimony to the fact that simply to see is not enough for many people; there is a feeling of lack of acquaintance until some direct contact is made. This demand for fuller and closer knowledge is quite different from any conscious interest in observation for its own sake. Desire for expansion, for "self-realization," is its motive. The interest is sympathetic, socially and æsthetically sympathetic, rather than cognitive. While the interest is especially keen in children (because their actual experience is so small and their possible experience so large), it still characterizes adults when routine has not blunted its edge. This sympathetic interest provides the medium for carrying and binding together what would otherwise be a multitude of items, diverse, disconnected, and of no intellectual use. These systems are indeed social and æsthetic rather than consciously intellectual; but they provide the natural medium for more conscious intellectual explorations. Some educators have recommended that nature study in the elementary schools be conducted with a love of nature and a cultivation of æsthetic appreciation in view rather than in a purely analytic spirit. Others have urged making much of the care of animals and plants. Both of these important recommendations have grown out of experience, not out of theory, but they afford excellent exemplifications of the theoretic point just made.
Analytic inspection for the sake of doing
Direct and indirect sense training
II. In normal development, specific analytic observations are originally connected almost exclusively with the imperative need for noting means and ends in carrying on activities. When one is doing something, one is compelled, if the work is to succeed (unless it is purely routine), to use eyes, ears, and sense of touch as guides to action. Without a constant and alert exercise of the senses, not even plays and games can go on; in any form of work, materials, obstacles, appliances, failures, and successes, must be intently watched. Sense-perception does not occur for its own sake or for purposes of training, but because it is an indispensable factor of success in doing what one is interested in doing. Although not designed for sense-training, this method effects sense-training in the most economical and thoroughgoing way. Various schemes have been designed by teachers for cultivating sharp and prompt observation of forms, as by writing words,—even in an unknown language,—making arrangements of figures and geometrical forms, and having pupils reproduce them after a momentary glance. Children often attain great skill in quick seeing and full reproducing of even complicated meaningless combinations. But such methods of training—however valuable as occasional games and diversions—compare very unfavorably with the training of eye and hand that comes as an incident of work with tools in wood or metals, or of gardening, cooking, or the care of animals. Training by isolated exercises leaves no deposit, leads nowhere; and even the technical skill acquired has little radiating power, or transferable value. Criticisms made upon the training of observation on the ground that many persons cannot correctly reproduce the forms and arrangement of the figures on the face of their watches misses the point because persons do not look at a watch to find out whether four o'clock is indicated by IIII or by IV, but to find out what time it is, and, if observation decides this matter, noting other details is irrelevant and a waste of time. In the training of observation the question of end and motive is all-important.
Scientific observations are linked to problems
"Object-lessons" rarely supply problems
III. The further, more intellectual or scientific, development of observation follows the line of the growth of practical into theoretical reflection already traced (ante, Chapter Ten). As problems emerge and are dwelt upon, observation is directed less to the facts that bear upon a practical aim and more upon what bears upon a problem as such. What makes observations in schools often intellectually ineffective is (more than anything else) that they are carried on independently of a sense of a problem that they serve to define or help to solve. The evil of this isolation is seen through the entire educational system, from the kindergarten, through the elementary and high schools, to the college. Almost everywhere may be found, at some time, recourse to observations as if they were of complete and final value in themselves, instead of the means of getting material that bears upon some difficulty and its solution. In the kindergarten are heaped up observations regarding geometrical forms, lines, surfaces, cubes, colors, and so on. In the elementary school, under the name of "object-lessons," the form and properties of objects,—apple, orange, chalk,—selected almost at random, are minutely noted, while under the name of "nature study" similar observations are directed upon leaves, stones, insects, selected in almost equally arbitrary fashion. In high school and college, laboratory and microscopic observations are carried on as if the accumulation of observed facts and the acquisition of skill in manipulation were educational ends in themselves.
Compare with these methods of isolated observations the statement of Jevons that observation as conducted by scientific men is effective "only when excited and guided by hope of verifying a theory"; and again, "the number of things which can be observed and experimented upon are infinite, and if we merely set to work to record facts without any distinct purpose, our records will have no value." Strictly speaking, the first statement of Jevons is too narrow. Scientific men institute observations not merely to test an idea (or suggested explanatory meaning), but also to locate the nature of a problem and thereby guide the formation of a hypothesis. But the principle of his remark, namely, that scientific men never make the accumulation of observations an end in itself, but always a means to a general intellectual conclusion, is absolutely sound. Until the force of this principle is adequately recognized in education, observation will be largely a matter of uninteresting dead work or of acquiring forms of technical skill that are not available as intellectual resources.
§ 2. Methods and Materials of Observation in the Schools
The best methods in use in our schools furnish many suggestions for giving observation its right place in mental training.
Observation should involve discovery
I. They rest upon the sound assumption that observation is an active process. Observation is exploration, inquiry for the sake of discovering something previously hidden and unknown, this something being needed in order to reach some end, practical or theoretical. Observation is to be discriminated from recognition, or perception of what is familiar. The identification of something already understood is, indeed, an indispensable function of further investigation (ante, p. 119); but it is relatively automatic and passive, while observation proper is searching and deliberate. Recognition refers to the already mastered; observation is concerned with mastering the unknown. The common notions that perception is like writing on a blank piece of paper, or like impressing an image on the mind as a seal is imprinted on wax or as a picture is formed on a photographic plate (notions that have played a disastrous rôle in educational methods), arise from a failure to distinguish between automatic recognition and the searching attitude of genuine observation.
and suspense during an unfolding change
II. Much assistance in the selection of appropriate material for observation may be derived from considering the eagerness and closeness of observation that attend the following of a story or drama. Alertness of observation is at its height wherever there is "plot interest." Why? Because of the balanced combination of the old and the new, of the
