Some seven or eight years ago the question, of how to teach children to study happened to be included in a list of topics that I hastily prepared for discussion with one of my classes. On my later examination of this problem I was much surprised, both at its difficulty and scope, and also at the extent to which it had been neglected by teachers. Ever since that time the two questions, How adults should study, and How children should be taught to study, have together been my chief hobby. The following ideas are partly the result of reading; but since there is a meagre quantity of literature bearing on this general theme, they are largely the result of observation, experiment, and discussion with my students. Many of the latter will recognize their own contributions in these pages, for I have endeavored to preserve and use every good suggestion that came from them; and I am glad to acknowledge here my indebtedness to them. In addition I must express my thanks for valuable criticisms to my colleague, Dr. George D. Strayer, and also to Dr. Lida B. Earhart, whose suggestive monograph on the same general subject has just preceded this publication. The Author. Part I Present Methods of Study; Nature of Study, and Its Principal Factors Chapter I Indications That Young People Do Not Learn to Study Properly; The SERIOUSNESS OF THE EVIL No doubt every one can recall peculiar methods of study that he or some one else has at some time followed. During my attendance at high school I often studied aloud at home, along with several other temporary or permanent members of the family. I remember becoming exasperated at times by one of my girl companions. She not only read her history aloud, but as she read she stopped to repeat each sentence five times with great vigor. Although the din interfered with my own work, I could not help but admire her endurance; for the physical labor of mastering a lesson was certainly equal to that of a good farm hand, for the same period of time. This way of studying history seemed extremely ridiculous. But the method pursued by myself and several others in beginning algebra at about the same time was not greatly superior. Our text-book contained several long sets of problems which were the terror of the class, and scarcely one of which we were able to solve alone. We had several friends, however, who could solve them, and, by calling upon them for help, we obtained the statement for each one. All these statements I memorized, and in that way I was able to pass off the subject. A few years later, when a school principal, I had a fifteen-year-old boy in my school who was intolerably lazy. His ambition was temporarily aroused, however, when he bought a new book and began the study of history. He happened to be the first one called upon, in the first recitation, and he started off finely. But soon he stopped, in the middle of a sentence, and sat down. When I asked him what was the matter, he simply replied that that was as far as he had got. Then, on glancing at the book, I saw that he had been reproducing the text verbatim, and the last word that he had uttered was the last word on the first page. These few examples suggest the extremes to which young people may go in their methods of study. The first instance might illustrate the muscular method of learning history; the second, the memoriter method of reasoning in mathematics. I have never been able to imagine how the boy, in the third case, went about his task; hence, I can suggest no name for his method. While these methods of study are ridiculous, I am not at all sure that they are in a high degree exceptional. Collective examples of study
