"The pupil too often has a choice only between beginning with a study of the results of prior specialization where the material is isolated from his daily experiences, or with miscellaneous nature study, where material is presented at haphazard and does not lead anywhere in particular. The habit of introducing college pupils into segregated scientific subject matter, such as is appropriate to the man who wishes to become an expert in a given field, is carried back into the high schools. Pupils in the latter simply get a more elementary treatment of the same thing, with difficulties smoothed over and topics reduced to the level of their supposed ability. The cause of this procedure lies in following tradition, rather than in conscious adherence to a dualistic philosophy. But the effect is the same as if the purpose were to inculcate an idea that the sciences which deal with nature have nothing to do with man, and vice versa. A large part of the comparative ineffectiveness of the teaching of the sciences, for those who never become scientific specialists, is the result of a separation which is unavoidable when one begins with technically organized subject matter. Even if all students were embryonic scientific specialists, it is questionable whether this is the most effective procedure. Considering that the great majority are concerned with the study of sciences only for its effect upon their mental habits — in making them more alert, more open-minded, more inclined to tentative acceptance and to testing of ideas propounded or suggested, — and for achieving a better understanding of their daily environment, it is certainly ill-advised. Too often the pupil comes out with a smattering which is too superficial to be scientific and too technical to be applicable to ordinary affairs.The utilization of ordinary experience to secure an advance into scientific material and method, while keeping the latter connected with familiar human interests, is easier to-day than it ever was before. The usual experience of all persons in civilized communities to-day is intimately associated with industrial processes and results. These in turn are so many cases of science in action. The stationary and traction steam engine, gasoline engine, automobile, telegraph and telephone, the electric motor enter directly into the lives of most individuals. Pupils at an early age are practically acquainted with these things. Not only does the business occupation of their parents depend upon scientific applications, household pursuits, the maintenance of health, the sights seen upon the streets, embody scientific achievements and stimulate interest in the connected scientific principles. The obvious pedagogical starting point of scientific instruction is not to teach things labeled science, but to utilize the familiar occupations and appliances to direct observation and experiment, until pupils have arrived at a knowledge of some fundamental principles by understanding them in their familiar practical workings."
