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 familiar and the unexpected. We hang on the lips of the story-teller because of the element of mental suspense. Alternatives are suggested, but are left ambiguous, so that our whole being questions: What befell next? Which way did things turn out? Contrast the ease and fullness with which a child notes all the salient traits of a story, with the labor and inadequacy of his observation of some dead and static thing where nothing raises a question or suggests alternative outcomes.

This "plot interest" manifested in activity,

When an individual is engaged in doing or making something (the activity not being of such a mechanical and habitual character that its outcome is assured), there is an analogous situation. Something is going to come of what is present to the sense, but just what is doubtful. The plot is unfolding toward success or failure, but just when or how is uncertain. Hence the keen and tense observation of conditions and results that attends constructive manual operations. Where the subject-matter is of a more impersonal sort, the same principle of movement toward a dénouement may apply. It is a commonplace that what is moving attracts notice when that which is at rest escapes it. Yet too often it would almost seem as if pains had been taken to deprive the material of school observations of all life and dramatic quality, to reduce it to a dead and inert form. Mere change is not enough, however. Vicissitude, alteration, motion, excite observation; but if they merely excite it, there is no thought. The changes must (like the incidents of a well-arranged story or plot) take place in a certain cumulative order; each successive change must at once remind us of its predecessor and arouse interest in its successor if observations of change are to be logically fruitful.

and in cycles of growth

Living beings, plants, and animals, fulfill the twofold requirement to an extraordinary degree. Where there is growth, there is motion, change, process; and there is also arrangement of the changes in a cycle. The first arouses, the second organizes, observation. Much of the extraordinary interest that children take in planting seeds and watching the stages of their growth is due to the fact that a drama is enacting before their eyes; there is something doing, each step of which is important in the destiny of the plant. The great practical improvements that have occurred of late years in the teaching of botany and zoölogy will be found, upon inspection, to involve treating plants and animals as beings that act, that do something, instead of as mere inert specimens having static properties to be inventoried, named, and registered. Treated in the latter fashion, observation is inevitably reduced to the falsely "analytic" (ante, p. 112),—to mere dissection and enumeration.
