The development of ideals is the most important task of the school. Honesty is more valuable than arithmetic, and industry is of greater importance than geography. Useful as information undoubtedly is, it is only a means toward an end, and this end is the proper development of the fundamental ideals. Although ideals are important, or perhaps because ideals are important, it is extremely difficult to develop high ideals in individual children. Teachers are constantly confronted with the problem of how to make untidy children desire to be neat, dishonest children willing to be honest, and lazy children anxious to be industrious. The most baffling problem that the teacher meets in discipline and classroom study is the development of valuable traits of character and personality. Seldom do the problems of teaching information cause worry and discouragement equal to the worry and discouragement caused by problems of discipline and personality. Yet the general procedure to be followed is comparatively simple. There are only five factors that a teacher has to take into account in teaching ideals. The specific methods of handling these factors in particular situations are frequently difficult to discover, but upon their discovery depends the success of the teacher in the development of character. Even though the applications are more difficult than the principles, general methods will be suggested for handling particular situations that will at least clarify the problem which many teachers find difficult of solution. For the purpose of presenting a simple organization of the fundamental methods of teaching ideals, we shall outline the five factors which must be considered in the development of all ideals.
