In considering any American educational question, there are one or two points which must never be lost sight of, and perhaps it will be well to indicate them here. In the first place, it must be remembered that there is not one American educational system, but many. Each State has complete control of its own educational matters, has its own School Law, sets aside common lands, or levies taxes for the support of its own schools, and is responsible to no higher authority. The only part taken by the Central Government of the United States in connection with education has been in the establishment of a Bureau of Education, the chief functions of which have been (1) the collecting of statistics and general information respecting education in all the various States, which are embodied in an annual report made by the Commissioner of Education, (2) the publishing of monographs and circulars of information on topics of educational interest, such as Co-education, Teaching of History, etc., and (3) the maintaining of a valuable Pedagogical Reference Library at Washington. Secondly, a distinction must be made between the Western States, of which Michigan might be taken as representative, and the Eastern, of which Massachusetts might be considered typical. In the former we find a most complete system of State education, leading from the Primary School right up to the great co-educational University of Michigan. The State Schools there have few private rivals, and the University none. In the State of Massachusetts, on the contrary, although Primary, Grammar and High Schools are maintained at the public expense, yet the children of a large proportion of the inhabitants attend private schools and academies, which undertake to prepare them for Harvard or the Women’s Colleges, such as Wellesley. In fact, few of those who enter upon a University career do so straight from the common school, as is the case in the Western States. It follows from this that there are two classes of teachers to be considered in the Eastern States--(1) those who teach in the common schools (Primary, Grammar and High), and (2) those who teach in private schools and in the academies. Those of the second class are largely recruited from the ranks of College graduates, who rely upon their University course as preparation for the profession of teaching, and amongst whom the idea of a special training for their work has only here and there been awakened. It is mainly in connection with State education that the idea of the training of teachers has been developed, although the fact that several of the older Universities, including Harvard, are providing courses of lectures on the Science and Art of Teaching may be taken as a hopeful sign of the gradual growth of the idea among all classes of teachers.
