There is an important law of learning and memory known as Jost’s law, which may be stated as follows: If we repeat or renew associations, the repetitions have most value for the old associations. Therefore when we learn, we should learn and then later relearn. This will make for permanent retention. Of course, if we wish to get together a great mass of facts for a temporary purpose and do not care to retain them permanently, cramming is the proper method. If we are required to pass an examination in which a knowledge of many details is expected and these details have no important permanent value, cramming is justified. When a lawyer is preparing a case to present to a court, the actual, detail evidence is of no permanent value, and cramming is justified.
But if we wish to acquire and organize facts for their permanent value, cramming is not the proper procedure. The proper procedure is for a student to go over his work faithfully as the term of school proceeds, then occasionally review. At the end of the term, a rapid review of the whole term’s work is valuable. After one has studied over matter and once carefully worked it out, a quick view again of the whole subject is most valuable, and assists greatly in making the acquisition permanent. But if the matter has not been worked out before, the hasty view of the material of the course, while it may enable one to pass the examination, has no permanent value.
Function of the Teacher in Memory Work. The function of a teacher is plainly to get the pupils to learn in accordance with the laws of memory above set forth; but there are certain things that a teacher can do that may not have become evident to the reader. It has been learned in experiments in logical memory that when a story is read to a subject and the subject attempts to reproduce it, certain mistakes are made. When the story is read again, it is common for the same mistakes to be made in the recall. Certain ideas were apprehended in a certain way; and, when the piece is read again, the subject pays no more attention to the ideas already acquired and reported, and they are therefore reported wrongly as they were in the first place. Often the subject does not notice the errors till his attention is called to them.
This suggests an important function of the teacher in connection with the memory work of the pupils. This function is to correct mistakes in the early stages of learning. A teacher should always be on the watch to find the errors of the pupils and to correct them before they are fixed by repetition.
A teacher should, also, consider it her duty to test the memory capacities of the pupils and to give each the advice that the case demands.
Some Educational Inferences.—There are certain consequences to education that follow from the facts of memory above set forth that are of considerable significance. Many things have been taught to children on the assumption that they could learn them better in childhood than later, because it was thought that memory and the learning capacity were better in childhood. But both of these assumptions are false. As children grow older their learning capacity increases and their memories become better.
It has particularly been held that rote memory is better in childhood and that therefore children should begin their foreign language study early. It is true that as far as speaking a foreign language is concerned, the earlier a child begins it the better. But this is not true of learning to read the language. The sounds of the foreign language that we have not learned in childhood in speaking the mother tongue are usually difficult for us to make. The organs of speech become set in the way of their early exercise. In reading the foreign language, correct pronunciation is not important. We are concerned with getting the thought, and this is possible without pronouncing at all. Reference to graphs on pages [190] and [191] will show that rote memory steadily improves throughout childhood and youth. The author has performed numerous experiments to test this very point. He has had adults work side by side with children at building up new associations of the rote memory type and found that always the adult could learn faster than the child and retain better what was learned.
The experience of language teachers in college and university does not give much comfort to those who claim that language study should be begun early. These teachers claim that the students who have had previous language study do no better than those who have had none. It seems, however, that there certainly ought to be some advantage in beginning language study early and spreading the study out over the high school period. But what is gained does not offset the tremendous loss that follows from requiring all high school students to study a foreign language merely to give an opportunity for early study to those who are to go on in the university with language courses. A mature university student that has a real interest in language and literature can begin his language study in the university and make rapid progress. Some of the best classical scholars whom the author knows began their language study in the university. While it would have been of some advantage to them to have begun their language study earlier, there are so few who should go into this kind of work that society cannot afford to make provision for their beginning the study in the high school.
The selection and arrangement of the studies in the curriculum must be based on other grounds than the laws of memory. What children make most progress in and need most to know are the concrete things of their physical and social environment. Children must first learn the world—the woods and streams and birds and flowers and plants and animals, the earth, its rocks and soils and the wonderful forces at work in it. They must learn man,—what he is and what he does and how he does it; how he lives and does his work and how he governs himself. They should also learn to read and to write their mother tongue, and should learn something of that great store of literature written in the mother tongue.
The few that are to be scholars in language and literature must wait till beginning professional study before taking up their foreign language; just as a person who is to be a lawyer or physician must also wait till time to enter a university before beginning special professional preparation. The child’s memory for abstract conceptions is particularly weak in early years; hence studies should be so arranged as to acquaint the child with the concrete aspects of the world first, and later to acquaint him with the abstract relations of things. Mathematics should come late in the child’s life, for the same reason. Mathematics deals with quantitative relations which the child can neither learn nor remember profitably and economically till he is more mature. The child should first learn the world in its descriptive aspects.
