EDUCATION

Dewey, John. Learning to earn: the place of vocational education in a comprehensive scheme of public education. (School and Society, March 24, 1917. p. 331-335.)

Address at the annual meeting of the Public Education Association, New York City, Feb. 20, 1917.

"The movement for vocational education conceals within itself two mighty and opposing forces, one which would utilize the public schools primarily to turn out more efficient

laborers in the present economic régime, with certain incidental advantages to themselves, the other which would utilize all the resources of public education to equip individuals to control their own future economic careers, and thus help on such a reorganization of industry as will change it from a feudalistic to a democratic order."

The author calls upon public-spirited educators to throw their influence "upon the side of education rather than of training, on that of democratic rather than that of feudal control of industry."

Says the editor of the magazine, in a note: "The experiences and conditions described in this article are typical of those in many a small city in all sections of the United States. For this reason the article has a value of national importance. In these days of cost accounting and cost analysis it is amazing to find a utility company in any state in the Union...that will take the position that the factors in street lighting costs cannot be itemized and segregated. Such a position has long been abandoned not only by progressive utility companies but as a rule by private businesses as well."
