In addition the boys should be taught the common technical terms used in trade hand books. The man who expects to advance in his trade will have to keep on learning after he leaves school. There are many avenues of information open to him, and the school can perform no more valuable service than to point the way to the sources of knowledge represented by reference books, trade journals, and other technical literature. Some of the popular magazines, such as "The Scientific American," "The Illustrated World," and "Popular Mechanics" can be used most effectively to bring home to the pupils the close connection existing between the class work and the outside world of science and invention.
Shop Work
It is difficult to determine the exact function of the manual training shop work in cabinet making and bookbinding which figures in the curriculum at present. That the work was not planned with vocational training in mind seems clear from the action of the school board in adding bookbinding to the course about the middle of the year. The bookbinding trade is one of the smallest in the city, and there is little probability that more than one boy among the total number enrolled in both junior high schools will enter it after leaving school.
Fully three-fourths of the industrial group will later be employed in occupations where most of the work is done with machines or machine tools. Even in the hand tool trades, such as carpentry, sheet metal work, cabinet making, and blacksmithing, the use of machines is constantly increasing. It would seem, therefore, that some acquaintance with different types of machines would be of considerable value to the pupils who may later enter industrial employment. The number of boys who are likely to become machinists is large enough to warrant the installation of a small machine shop. Repairing, assembling, and taking apart machines should occupy an important place in the shop course. Most boys are intensely interested in getting at the "insides" of a machine, and the processes of assembling, with their attendant problems of adjustment and co-ordination of mechanical movements, afford opportunities for the best kind of practical instruction. One of the great advantages of this type of shop work lies in the fact that it consumes little or no material and is therefore inexpensive; another is that a fairly extensive equipment can be easily obtained, as any machine, old or new, will serve the purpose and may be used over and over again.
The extent and variety of shop equipment will depend largely on the resources of the school system. The more the better, so long as the money is expended on the principle of the greatest good to the greatest number, which means that the kinds of tools and equipment used in the large trades should be preferred to those used only in the smaller trades.
In order that the time devoted to shop work may yield its greatest results, it is necessary that every lesson center around knowledge and ability that will be of real subsequent use to the pupils. It must not run to "art" and it must not be mere tinkering. Its principal value as vocational training, in the last analysis, lies in its use as an objective medium for the teaching of industrial mathematics and science.
Vocational Information
During the second and third years all the boys who elect the industrial course or who expect to leave school at the end of the compulsory attendance period should be required to devote some time each week to the study of economic and working conditions in wage earning industrial and commercial occupations. A clear understanding of the comparative advantages of different kinds of employment is of the highest importance at this period of the boy's life. It seems to be generally assumed that an adequate basis of knowledge for the selection of an industrial vocation is an acquaintance with materials and processes. Such knowledge is valuable, but making a living is mainly an economic problem. What an occupation means in terms of income is more significant than what it means in terms of materials. The most important facts about the cabinet making trade, for example, are that it offers very few opportunities for employment to public school boys, and that it is one of the lowest paid skilled trades. The primary considerations in the intelligent selection of a vocation relate to wages, steadiness of employment, health risks, opportunities for advancement, apprenticeship conditions, union regulations, and the number of chances there are for getting into it. These things are fundamental, and any one of them may well take precedence over the matter of whether the tastes of the future wage-earner run to wood, brick, stone, or steel.
