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.
Observation of structure grows out of noting function
There is, of course, a place, and an important place, for observation of the mere static qualities of objects. When, however, the primary interest is in function, in what the object does, there is a motive for more minute analytic study, for the observation of structure. Interest in noting an activity passes insensibly into noting how the activity is carried on; the interest in what is accomplished passes over into an interest in the organs of its accomplishing. But when the beginning is made with the morphological, the anatomical, the noting of peculiarities of form, size, color, and distribution of parts, the material is so cut off from significance as to be dead and dull. It is as natural for children to look intently for the stomata of a plant after they have become interested in its function of breathing, as it is repulsive to attend minutely to them when they are considered as isolated peculiarities of structure.
Scientific observation
III. As the center of interest of observations becomes less personal, less a matter of means for effecting one's own ends, and less æsthetic, less a matter of contribution of parts to a total emotional effect, observation becomes more consciously intellectual in quality. Pupils learn to observe for the sake (i) of finding out what sort of perplexity confronts them; (ii) of inferring hypothetical explanations for the puzzling features that observation reveals; and (iii) of testing the ideas thus suggested.
should be extensive
and intensive
In short, observation becomes scientific in nature. Of such observations it may be said that they should follow a rhythm between the extensive and the intensive. Problems become definite, and suggested explanations significant by a certain alternation between a wide and somewhat loose soaking in of relevant facts and a minutely accurate study of a few selected facts. The wider, less exact observation is necessary to give the student a feeling for the reality of the field of inquiry, a sense of its bearings and possibilities, and to store his mind with materials that imagination may transform into suggestions. The intensive study is necessary for limiting the problem, and for securing the conditions of experimental testing. As the latter by itself is too specialized and technical to arouse intellectual growth, the former by itself is too superficial and scattering for control of intellectual development. In the sciences of life, field study, excursions, acquaintance with living things in their natural habitats, may alternate with microscopic and laboratory observation. In the physical sciences, phenomena of light, of heat, of electricity, of moisture, of gravity, in their broad setting in nature—their physiographic setting—should prepare for an exact study of selected facts under conditions of laboratory control. In this way, the student gets the benefit of technical scientific methods of discovery and testing, while he retains his sense of the identity of the laboratory modes of energy with large out-of-door realities, thereby avoiding the impression (that so often accrues) that the facts studied are peculiar to the laboratory.
§ 3. Communication of Information
Importance of hearsay acquaintance
When all is said and done the field of fact open to any one observer by himself is narrow. Into every one of our beliefs, even those that we have worked out under the conditions of utmost personal, first-hand acquaintance, much has insensibly entered from what we have heard or read of the observations and conclusions of others. In spite of the great extension of direct observation in our schools, the vast bulk of educational subject-matter is derived from other sources—from text-book, lecture, and viva-voce interchange. No educational question is of greater import than how to get the most logical good out of learning through transmission from others.
Logically, this ranks only as evidence or testimony
Doubtless the chief meaning associated with the word instruction is this conveying and instilling of the results of the observations and inferences of others. Doubtless the undue prominence in education of the ideal of amassing information (ante, p. 52) has its source in the prominence of the learning of other persons. The problem then is how to convert it into an intellectual asset. In logical terms, the material supplied from the experience of others is testimony: that is to say, evidence submitted by others to be employed by one's own judgment in reaching a conclusion. How shall we treat the subject-matter supplied by text-book and teacher so that it shall rank as material for reflective inquiry, not as ready-made intellectual pabulum to be accepted and swallowed just as supplied by the store?
Communication by others should not encroach on observation,
In reply to this question, we may say (i) that the communication of material should be needed. That is to say, it should be such as cannot readily be attained by personal observation. For teacher or book to cram pupils with facts which, with little more trouble, they could discover by direct inquiry is to violate their intellectual integrity by cultivating mental servility. This does not mean that the material supplied through communication of others should be meager or scanty. With the utmost range of the senses, the world of nature and history stretches out almost infinitely beyond. But the fields within which direct observation is feasible should be carefully chosen and sacredly protected.
should not be dogmatic in tone,
(ii) Material should be supplied by way of stimulus, not with dogmatic finality and rigidity. When pupils get the notion that any field of study has been definitely surveyed, that knowledge about it is exhaustive and final, they may continue docile pupils, but they cease to be students. All thinking whatsoever—so be it is thinking—contains a phase of originality.
