Many, many a teacher has failed, thinking himself not wise enough, or not energetic enough, while in reality he has simply failed to be wisely and energetically quizzical.
But what is a question? Is it not a fish-hook for pulling out, rather than a siphon for putting in? Yes, later; but you cannot fish successfully in a dry pond. Any bungler can examine and test. The nice art is to use your interrogation-points as instruments of addition, rather than of subtraction.
But why is it often better to insinuate instruction through a question, in preference to pouring by direct harangue? Well, does not a question imply community of interest, and hint at equality or similarity of attainment? The question is neighborly; the discourse mounts a platform.
The helpful lesson commentaries fail, practically, to reach many a class, because its teacher in reading has failed to translate from the declarative into the interrogative. If Doctor Somebody writes tersely, "A sin that is born of your own will is tenfold more dangerous to you than your own sin that is born of your neighbor's will," Johnny will not get the point unless the teacher transforms it somewhat thus: "If you are out in the country all alone, Johnny, jump over a fence, steal a pocketful of apples, is that a sin just as much as if some other boy should be along and persuade you to do it? Yes? Well, now, which sin is the more dangerous to you?"
So important does this seem to me that I always carry pencil and paper to the perusal of my lesson helps, and write out, as a point pleases me, the form in which I wish to bring it up in the class, ranging these questions under the numbers of the verses to which they apply.
The teacher who does not write out his questions, or do the equivalent of that work, is as sure to be defeated as the general who fights without a plan of campaign.
Should those questions be read in the class? Not unless your ideal of teaching is the company drill, instead of the conversation.
It is well, however, to ask the scholars to write out questions for you on verses assigned, and read these questions before the class. The teacher's work is grandly accomplished when he has induced the scholar to ask his own questions, and work out his own answers.
I often find that a general call for questions on some apparently exhausted topic brings the richest results of the half-hour.
