But how may the uninitiated know a good question when they see it, or make it? As said already, it must not be such that a lazy monosyllable may answer it. As said already, too, if one is in doubt, he has but to try it on the class, and note results. But further. A good question will be likely to have something piquant about it, if the subject admits. For instance, "James was killed, Peter was freed; why was that?" is better than saying, "How do you account for the fact that while the apostle James was beheaded, the apostle Peter was delivered from the hands of his persecutors?"
Furthermore, the difference between a poor question and a good one may often be a mere matter of length. "Why did the Christians at Antioch keep the inferior leaders for work in the city, but send away the most prominent men in their church to labor as missionaries?" That is abominable; it should be, "Why did the Antioch Christians send away their best men?"
A good question will contain as much as possible of the personal element. "What do you understand by the phrase 'remission of sins'?" is much better than "What is the significance of the phrase 'remission of sins'?" Because the personal question puts the expected answer in a more modest light, the answer will be more unconstrained and full.
And, by the way, there are few forms of questions more zealously to be avoided than the form I have just used, "What do you understand by—?" It is the unfailing resource of the poor questioner. A verse will be read, a phrase quoted, a doctrine or a principle named, and then will follow, as the night the day, the tiresome old formula, "What do you understand by this, Miss A——?" One would be quite safe in declaring, at any particular instant during common Sunday-school hours, that one-fourth of the Sunday-school teachers of the world were repeating, with united breath, that Methuselah of a query, "What do you understand by this?"
Again, a good question must be swift. It must come so quickly that there will be no time to get out of the way. Some questions that, if written out, would not be bad, are prolonged in the utterance of over-deliberate teachers like foggy illustrations of the law of perspective. Good questions leap. You feel their buoyancy as you read them or hear them. It is like the huntsman springing into the saddle and shouting, "Come on!" No one with an atom of thoughtfulness is dull to the exhilaration of spirited questions. They have inspired all the wise thinking of the world.
And, finally, good questions should be absolutely clear. There is one thing in the world that must always be faultlessly perspicuous and distinct, and that is a marching order in time of battle. Now, questions are the marching orders of our scholars' brain regiments, in a battle of infinite moment. Let them ring clearly as ever bugle-call was sounded. Questions mumbled, hesitant, caught up and patched over, confused and slovenly,—what wonder if these get slow and mumbled answers? A question clearly put, not only proves that the questioner has clear ideas, but it wondrously clarifies the ideas of the answerer.
Good questions, then, are thought-compelling, varied, short, personal, piquant, unhackneyed, brisk, and clear. Do I ask too much? Nothing that all may not acquire, if but a tithe of the zeal and labor claimed by the trivialities of a few years are spent upon these issues of eternity. Let every teacher consider what characteristics of a good questioner he may add to his pedagogical outfit.
