4. The question-and-answer method
The question-and-answer method is so familiar to every one that it requires no formal definition. It is employed in all grades from the primary to the university, and it is adapted alike to testing, teaching, and drilling.
This method admits of wide modification to suit it to specific uses. The questions asked may require but a short and simple answer, such as can be given by a primary pupil. They may also require a long and complex answer which will test the powers of the most advanced student. The questions may be detailed and searching, covering every point of the lesson, as when we are testing preparation. They may deal only with certain related truths, as when we "develop" a new subject intentionally by questions and answers. Or they may select only the most important points upon which the class needs drill.
a. When and where to employ the question-and-answer method.--The question-and-answer method is particularly adapted to the lower grades, in which the children have not yet developed the ability to recite independently on long topics. This method allows the teacher to encourage and draw out the child by what is really a conversation between the two, the teacher asking simple questions and the child responding to them. In more advanced grades the questions may be so arranged as to require longer and more complex answers, and thus lead up to the topical method of reciting.
The question-and-answer method is also suitable to employ at the beginning of a recitation to recall to the minds of the class previous lessons to which the lesson of the day is related. There is hardly one recitation in a hundred that does not require an introduction of this kind. The only true method in teaching is to build the new knowledge on the related old knowledge which is already in the mind. This is what is meant in pedagogy by "proceeding from the known to the related unknown." And the known must always be fresh and immediately present to the mind. Hence the necessity for the introductory review.
This method is also serviceable in reviewing former lessons. By the use of well-selected questions a large number of important points already passed over can be brought before the class in a short time.
On the whole, it is probable that we do not review frequently enough in our recitation work. We review a subject when we have finished the text upon it, or before examination time, but this is not enough. Careful psychological tests have shown that the mind forgets within the first three days a large proportion of what it will finally fail to retain. Further, there is great economy in catching up a fading fact before it gets wholly away from us. This would suggest the constant use of the question-and-answer method to fix more firmly the important points in ground we have already passed over.
One of the most important uses of this method is found in inductive teaching. The famous "Socratic method" was simply the question-and-answer method applied by Socrates to teaching new truths. This noted teacher would, by a series of skillful questions calculated to call forth what the pupil already knew, lead him on to new knowledge without actually telling the youth anything himself. And this is the very height of good teaching--the goal toward which we all should strive.
It is a safe maxim never to tell a child what one can lead him by questioning to see for himself. To illustrate: Suppose an elementary arithmetic class already know thoroughly how to find the area of a rectangle by multiplying its base by its altitude, and that we are now ready to teach them how to find the area of a triangle. Let us see whether we can lead them to "develop" the rule instead of learning it out of the text; that is, we will proceed inductively. First draw a rectangle 4 by 6 on the board.
Q. What do we call this figure?
A. A rectangle.
Q. How shall we find its area?
A. Multiply its base 4 by its altitude 6; the area is 24.
Q. Now I draw a line diagonally across the rectangle; how many figures are there?
A. Two. (Teacher here gives new word "triangle" and explains it.)
Q. How do the base and altitude of the triangles compare with the base and altitude of the rectangle?
A. They are the same.
Q. How do the two triangles compare in area?
A. They are equal; each is half of the rectangle.
Q. Then, if each is half of the rectangle, what must be the area of one of the triangles?
A. The area of each triangle is 12, for the area of the rectangle is 24, and the area of each triangle is half that of the rectangle.
