The memory should play an important part in religion. Gems from the Bible, stories, characters, and events, inspiring thoughts and maxims, and many other such things should become a permanent part of the furnishing of the mind, recorded and faithfully preserved by the memory.
Laws of use of memory.—The laws by which the memory works have been thoroughly studied and carefully described, and should be fully understood by every teacher. Further than this, they should be faithfully observed in all memory work. These laws may be stated as follows:
1. The law of complete registration. The first act in the memory process is fully and completely to register, or learn, the matter to be retained. The retention can never be better than the registration of the facts given into the memory's keeping. Half-learned matter easily slips away, never having been completely impressed on the mind. It is possible to lose both effort and efficiency by committing a verse of a poem barely up to the point where it can doubtfully be repeated instead of giving it the relatively small amount of additional study and practice which would register it firmly and completely. Whatever is worth committing to memory should therefore be carried past the barely known stage and committed fully and completely.
2. The law of multiple association. This only means that the new facts learned shall be related as closely as may be to matter already in the mind. And this is equivalent to saying that the material learned shall be understood, its meaning grasped and its significance comprehended. To understand for yourself the value of association, make this experiment: Have some one write down a list of ten unrelated words in a column, and hold the list before you while you have time to read it over just once slowly and carefully. Now try repeating the words in order from memory. Next, have your friend write ten other words which this time form a connected sentence. After reading these words over once as you did the first list, try repeating them in order. You find that you have much trouble to memorize the first list, while the second presents no difficulty at all. The difference lies in the fact that the words of the first list were unrelated, lacking all associative connections with each other, while those of the second list formed a connected chain of associations.
It is possible to give the child biblical or other matter to memorize that has little more meaning to him than the list of unrelated words have to us. For example, this text is required of primary and junior children in a lesson series: "Ye shall know the truth, and the truth shall make you free." And this: "Let us therefore draw near with boldness unto the throne of grace, that we may receive mercy, and may find grace to help us in time of need." It is evident that younger children could by no possibility understand either of these beautiful passages, and hence in committing them will only be learning so many unrelated words.
The same is true of church catechisms. The memorizing of such material will be difficult and unpleasant, and no value will come from it. The most likely outcome of such ill-advised requirements is to discourage the child and make him dislike the church school and all its work. It is not to be expected that the child will understand the full meaning of every bit of matter suitable for him to memorize; this will have to await broader experience and fuller development. The material should, however, be sufficiently comprehended that its general meaning is clear and its significance understood.
3. The law of vividness of impression. The relation of vividness of impression to learning has already been discussed in another chapter. In no one of the mind's activities is vividness a more important factor than in memorizing. Matter committed under the stimulus of high interest and keen attention is relatively secure, while matter committed under slack concentration is sure to fade quickly from the memory. Songs can therefore best be committed under the elation of the interesting singing of the words; a verse of poetry, when the mind is alert and the feelings aroused by a story in which the sentiment of the verse fits; a prayer when the spirit of devotion has been quickened by worship. To insure full vividness the imagination must also be called upon to picture and make real such parts of memory material as contain imagery.
4. The law of repetition. For most minds memory depends on repetition. The impressions must be deepened and made lasting by being stamped again and again on the mind. The neurons of the brain which do the work of retaining and recalling must be made to repeat the process over and over until their action is secure. It is therefore not enough to make sure that the child has his memory material committed for this particular Sunday. If the matter was worth committing in the first place, it is worth keeping permanently. If it is to be kept permanently, it must be frequently reviewed; for otherwise it will surely be forgotten. It is to be feared that much, if not most, of the matter memorized by the pupils in many church schools lasts only long enough to show the teacher that it has once been learned, and that not many children know in any permanent sense the Bible passages they have committed. In so far as this is true it would be much better to select a smaller amount of the choicest and best adapted material to be found, and then so thoroughly teach this that it is permanently retained.
5. The law of wholes instead of parts. Many persons in setting at work to commit a poem, a Bible passage, a psalm have a tendency to learn it first by verses or sections and then, put the parts together to form the whole. Tests upon the memory have shown, that this is a less economical and efficient method than from the first to commit the material as a whole. This method requires that we go over all of it completely from beginning to end, then over it again, and so on until we can repeat much of it without reference to the text. We then refer to the text for what the memory has not yet grasped, requiring the memory to repeat all that has been committed, until the whole is in this manner fully learned. The method of learning by wholes not only requires less time and effort, but gives a better sense of unity in the matter committed.
6. The law of divided practice. If to learn a certain piece of material the child must go over it, say, fifteen times, the results are much better if the whole number of repetitions are not carried out at one time. Time seems necessary to give the associations an opportunity to set up their relationships; also, the interval between repetitions allows the parts that are hardest to commit to begin fading out, and thereby reveal where further practice is demanded. Where songs, Bible verses, or other material are committed in the lesson hour, provision ought to be made for the children to continue study and practice on the material at home during the week. The so-called cramming process of learning will not work any better in the church school than in the day-school lessons.
