prior analysis of reflection
If we compare this account of the methods of instruction with our own analysis of a complete operation of thinking, we are struck by obvious resemblances. In our statement (compare Chapter Six) the "steps" are the occurrence of a problem or a puzzling phenomenon; then observation, inspection of facts, to locate and clear up the problem; then the formation of a hypothesis or the suggestion of a possible solution together with its elaboration by reasoning; then the testing of the elaborated idea by using it as a guide to new observations and experimentations. In each account, there is the sequence of (i) specific facts and events, (ii) ideas and reasonings, and (iii) application of their result to specific facts. In each case, the movement is inductive-deductive. We are struck also by one difference: the Herbartian method makes no reference to a difficulty, a discrepancy requiring explanation, as the origin and stimulus of the whole process. As a consequence, it often seems as if the Herbartian method deals with thought simply as an incident in the process of acquiring information, instead of treating the latter as an incident in the process of developing thought.
The formal steps concern the teacher's preparation rather than the recitation itself
Before following up this comparison in more detail, we may raise the question whether the recitation should, in any case, follow a uniform prescribed series of steps—even if it be admitted that this series expresses the normal logical order. In reply, it may be said that just because the order is logical, it represents the survey of subject-matter made by one who already understands it, not the path of progress followed by a mind that is learning. The former may describe a uniform straight-way course, the latter must be a series of tacks, of zigzag movements back and forth. In short, the formal steps indicate the points that should be covered by the teacher in preparing to conduct a recitation, but should not prescribe the actual course of teaching.
The teacher's problem
Lack of any preparation on the part of a teacher leads, of course, to a random, haphazard recitation, its success depending on the inspiration of the moment, which may or may not come. Preparation in simply the subject-matter conduces to a rigid order, the teacher examining pupils on their exact knowledge of their text. But the teacher's problem—as a teacher—does not reside in mastering a subject-matter, but in adjusting a subject-matter to the nurture of thought. Now the formal steps indicate excellently well the questions a teacher should ask in working out the problem of teaching a topic. What preparation have my pupils for attacking this subject? What familiar experiences of theirs are available? What have they already learned that will come to their assistance? How shall I present the matter so as to fit economically and effectively into their present equipment? What pictures shall I show? To what objects shall I call their attention? What incidents shall I relate? What comparisons shall I lead them to draw, what similarities to recognize? What is the general principle toward which the whole discussion should point as its conclusion? By what applications shall I try to fix, to clear up, and to make real their grasp of this general principle? What activities of their own may bring it home to them as a genuinely significant principle?
Only flexibility of procedure gives a recitation vitality
Any step may come first
No teacher can fail to teach better if he has considered such questions somewhat systematically. But the more the teacher has reflected upon pupils' probable intellectual response to a topic from the various stand-points indicated by the five formal steps, the more he will be prepared to conduct the recitation in a flexible and free way, and yet not let the subject go to pieces and the pupils' attention drift in all directions; the less necessary will he find it, in order to preserve a semblance of intellectual order, to follow some one uniform scheme. He will be ready to take advantage of any sign of vital response that shows itself from any direction. One pupil may already have some inkling—probably erroneous—of a general principle. Application may then come at the very beginning in order to show that the principle will not work, and thereby induce search for new facts and a new generalization. Or the abrupt presentation of some fact or object may so stimulate the minds of pupils as to render quite superfluous any preliminary preparation. If pupils' minds are at work at all, it is quite impossible that they should wait until the teacher has conscientiously taken them through the steps of preparation, presentation, and comparison before they form at least a working hypothesis or generalization. Moreover, unless comparison of the familiar and the unfamiliar is introduced at the beginning, both preparation and presentation will be aimless and without logical motive, isolated, and in so far meaningless. The student's mind cannot be prepared at large, but only for something in particular, and presentation is usually the best way of evoking associations. The emphasis may fall now on the familiar concept that will help grasp the new, now on the new facts that frame the problem; but in either case it is comparison and contrast with the other term of the pair which gives either its force. In short, to transfer the logical steps from the points that the teacher needs to consider to uniform successive steps in the conduct of a recitation, is to impose the logical review of a mind that already understands the subject, upon the mind that is struggling to comprehend it, and thereby to obstruct the logic of the student's own mind.
§ 2. The Factors in the Recitation
Bearing in mind that the formal steps represent intertwined factors of a student's progress and not mileposts on a beaten highway, we may consider each by itself. In so doing, it will be convenient to follow the example of many of the Herbartians and reduce the steps to three: first, the apprehension of specific or particular facts; second, rational generalization; third, application and verification.
Preparation is getting the sense of a problem
I. The processes having to do with particular facts are preparation and presentation. The best, indeed the only preparation is arousal to a perception of something that needs explanation, something unexpected, puzzling, peculiar. When the feeling of a genuine perplexity lays hold of any mind (no matter how the feeling arises), that mind is alert and inquiring, because stimulated from within. The shock, the bite, of a question will force the mind to go wherever it is capable of going, better than will the most ingenious pedagogical devices unaccompanied by this mental ardor. It is the sense of a problem that forces the mind to a survey and recall of the past to discover what the question means and how it may be dealt with.
Pitfalls in preparation
The teacher in his more deliberate attempts to call into play the familiar elements in a student's experience, must guard against certain dangers. (i) The step of preparation must not be too long continued or too exhaustive, or it defeats its own end. The pupil loses interest and is bored, when a plunge in medias res might have braced him to his work. The preparation part of the recitation period of some conscientious teachers reminds one of the boy who takes so long a run in order to gain headway for a jump that when he reaches the line, he is too tired to jump far. (ii) The organs by which we apprehend new material are our habits. To insist too minutely upon turning over habitual dispositions into conscious ideas is to interfere with their best workings. Some factors of familiar experience must indeed be brought to conscious recognition, just as transplanting is necessary for the best growth of some plants. But it is fatal to be forever digging up either experiences or plants to see how they are getting along. Constraint, self-consciousness, embarrassment, are the consequence of too much conscious refurbishing of familiar experiences.
Statement of aim of lesson
Strict Herbartians generally lay it down that statement—by the teacher—of the aim of a lesson is an indispensable part of preparation. This preliminary statement of the aim of the lesson hardly seems more intellectual in character, however, than tapping a bell or giving any other signal for attention and transfer of thoughts from diverting subjects. To the teacher the statement of an end is significant, because he has already been at the end; from a pupil's standpoint the statement of what he is going to learn is something of an Irish bull. If the statement of the aim is taken too seriously by the instructor, as meaning more than a signal to attention, its probable result is forestalling the pupil's own reaction, relieving him of the responsibility of developing a problem and thus arresting his mental initiative.
