=Interest versus Interests.=--On account of the evident connection of interest and attention, the teacher may easily err in dealing with the young pupil. It is allowable, as pointed out above, that the teacher should take advantage of any native interest to secure the attention and effort of the child in his school work. This does not mean, however, that children are to be given only problems in which they are naturally interested. It must be remembered, as seen in a former paragraph, that, according to the interest of custom, any line of school work, when intelligently followed, may soon build up a centre of interest for itself. For this reason a proper study of arithmetic should develop an interest in arithmetic; a study of history, an interest in history; and a study of geography, an interest in geography. The saying that school work should follow a child's interest might, therefore, be better expressed by saying that the child's interests should follow the school work. It is only, in fact, as any one becomes directly interested in his pursuits, that the highest achievement can be reached. It is not the workman who is always looking forward to pay-day, who develops into an artist, or the teacher who is waiting for the summer holiday, who is a real inspiration to her pupils. In like manner, it is only as the child forms centres of interest in connection with his school work, that his life and character are likely to be affected permanently thereby. =Development of Interests.=--The problem for the educator is, therefore, not so much to follow the interest of the child, as it is to develop in him permanent centres of interest. For this reason the following facts concerning the origin and development of interests should be understood by the practical educator. First among these is the fact that certain instinctive tendencies of early childhood may be made a starting-point for the development of permanent valuable interest. The young child has a tendency to collect or an instinct of ownership, which may be taken advantage of in directing him to make collections of insects, plants, coins, stamps, and thus prove of permanent educative value. His constructive tendencies, or desire to do with what comes into his hand, as well as his imitative instincts, may be turned to account in building up an interest in various occupations. His social instinct, also, provides a means for developing permanent emotional interests as sympathy, etc. In like manner, the character of the child's surroundings tends to create in him various centres of interest. The young child, for instance, who is surrounded with beautiful objects, is almost sure to develop an interest in works of art, while the child who is early provided with fable and story will develop an interest in history.
