Chapter 6
THE JUNIOR HIGH SCHOOL
In 1915 the Board of Education authorized the establishment of a system of junior high schools in the city, and at the beginning of the school year of 1915-16 the new plan was inaugurated in two schools. The Empire Junior High School, situated in the eastern part of the city, had an enrollment of about 700 children made up of seventh and eighth grade pupils formerly accommodated in the elementary schools of that section. The Detroit Junior High School on the west side had an enrollment of about 400 pupils. No decision has yet been reached as to whether the course shall include only two years' work, or three years, as in other cities of the country where the junior high school plan has been adopted.
A comparison of the course with that for corresponding grades of the elementary schools shows some marked differences. Less time is devoted to English in the junior high school and considerably more to arithmetic, geography, and history. Mechanical drawing, not taught in the elementary schools except incidentally in the manual training classes, is given an hour each week. All boys receive one hour of manual training a week against slightly less than one and one-half hours in the seventh and eighth elementary grades, but they may elect an additional two and one-half hours a week in this subject, together with applied arithmetic during the first year, or with bookkeeping during the second. Girls may elect an additional two and one-half hours a week of domestic science, with bookkeeping. The manual training for boys comprises woodwork and bookbinding.
SPECIALIZED TRAINING NOT PRACTICABLE
In the junior high school, as in the elementary school, the greatest difficulty in the way of trade training for specific occupations lies in the small number of pupils who can be expected, within the bounds of reasonable probability, to enter a single trade. Hand and machine composition, the largest of the printing trades, will serve as an example. In a junior high school of 1,000 pupils, boys and girls, the number of boys who are likely to become compositors is about five. But to teach this trade printing equipment occupying considerable space is necessary, together with a teacher who has had some experience or training as a printer. The expense per pupil for equipment, for the space it occupies, and for instruction renders special training for such small classes impracticable. All of the skilled occupations, with the exception perhaps of the machinist's trade, are in the same case. An attempt to form separate classes for each of the eight largest trades in the city would result in two classes of not over five pupils, three classes of not over 10 pupils, and only one of over 13 pupils. The following table shows the number of boys, in a school of this size, who are likely to enter each of these trades.

A GENERAL INDUSTRIAL COURSE
The members of the Survey Staff were, however, of the opinion that through the system of electives in the junior high school, industrial training of a more general type, made up chiefly of instruction in the applications of mathematics, drawing, physics, and chemistry to the commoner industrial processes, would be of considerable benefit to those boys who, on the basis of their own selection or that of their parents, are likely to enter industrial pursuits. A course of this kind is outlined in following sections of this chapter.
The objections which may be brought against this plan are frankly recognized. It takes into account only the interests of the industrial group, comprising less than one-half of the boys in the school. Unquestionably it would tend to vitalize the teaching of mathematics, drawing, and science for the boys who enroll in the industrial course, but it leaves unsolved the question of method and content of instruction in these subjects for the boys in the non-industrial or so-called academic course. Very possibly future experience may demonstrate that the plan recommended for the general industrial course affords the best medium for teaching science and mathematics at this period to all pupils, in which case a differentiated course would be unnecessary.
The organization of vocational training in junior high school grades presents many difficulties which cannot be solved by a more or less abstract study of educational and industrial needs. Experimentation on an extensive scale, covering a considerable period of time, is necessary before definite conclusions can be drawn as to the limitations and possibilities of such work. It is with a full appreciation of this fact that the following suggestive outline is presented.
The purpose of the general industrial course is to afford to boys who wish to enter industrial occupations the opportunity to secure knowledge and training that will be of direct or indirect value to them in industrial employment. It is not expected that by this means they can be given much practical training in hand work for any particular trade. The most the school can do for the boy at this period is to bridge over for him the gap that exists between the knowledge he obtains from books and the rôle which this knowledge plays in the working world. It must not be assumed that the transition can be effected merely by the introduction of shop work, even if it were possible to provide the wide variety of manual training necessary to make up a fair representation of the principal occupations into which the boys will enter when they leave school. It is doubtful whether, so far as its vocational value is concerned, shop work isolated from other subjects of the curriculum is worth any more per unit of time devoted to it than several of the so-called academic subjects. This is particularly true of the two most common types of manual training--cabinet making and forge work. Both represent dying trades. During the decade 1900-1910 the increase in the number of cabinet makers in Cleveland fell far below the general increase in population. The blacksmiths made a still poorer showing. Both trades are recruited mainly from abroad and the relative number of Americans employed in them is steadily declining.
In the opinion of the Survey Staff a general industrial course should cover instruction in at least the following five subjects: Industrial mathematics, mechanical drawing, industrial science, shop work, and the study of economic and working conditions in wage earning pursuits. These may be offered as independent electives or they may be required of all pupils who elect the industrial course. The details of organization must, of course, be worked out by trial and experiment. They will probably vary in different schools and from year to year.
INDUSTRIAL MATHEMATICS
Of the hundreds of employers who were interviewed by members of the Survey Staff as to the technical equipment needed by beginners in the various trades, nearly all emphasized the ability to apply the principles of simple arithmetic quickly, correctly, and accurately to industrial problems. Many employers criticized the present methods of teaching this subject in the public schools. In the main their criticisms were to the effect that the teaching was not "practical." "The boys I get may know arithmetic," said one, "but they haven't any mathematical sense." Another cited his experience with an apprentice who was told to cut a bar eight and one-half feet long into five pieces of equal length. He was not told the length of the bar, but was given the direct order: "Cut that bar into five pieces all of the same size." The boy was unable to lay out the work, although when asked by the foreman, "Don't you know how to divide 81/2 by 5?", he performed the arithmetical operation without difficulty. The employer gave this instance as an illustration of what to his mind constituted one of the principal defects of public school teaching. "Mere knowledge of mathematical principles and the ability to solve abstract problems is not enough," he said. "What the boys get in the schools is mathematical skill, but what they need in their work is mathematical intelligence. The first does not necessarily imply the second."
This mathematical intelligence can be developed only through practice in the solution of practical problems, that is, problems which are stated in the every day terms of the working world and which require the student to go through the successive mental steps in the same way that he would if he were working in a shop. The problem referred to above is one of division of fractions. If we state it thus: "81/2÷5," the pupil takes pencil and paper, performs the operation and announces the result. If we say, "A bar 81/2 feet long is to be cut into five pieces of equal length; how long should each piece be?", the problem calls for the exercise of greater intelligence, as the pupil must determine which process to use in order to obtain the correct result. It becomes still more difficult if we merely show him the bar and say: "This bar must be cut into five pieces of equal length; how long will each piece be?" Several additional preliminary steps are required, none of which was involved in the problem in its original form. Before the length of the pieces can be computed he must find out the length of the bar. He must know what to measure it with, and in what terms, whether feet or inches, the problem should be stated. Again, if we say: "Lay this bar out to be cut in five equal lengths," another step--the measurement and marking for each cut--is added. Many variations might be introduced, each involving additional opportunities for the exercise of thought.
It is through practice in solving problems of this kind that the pupil acquires what the employer called mathematical intelligence. It consists in the ability to note what elements are involved in the problems and to decide which process of arithmetic should be used in dealing with them. Once these decisions are made the succeeding arithmetical calculations are simple and easy. In technical terms the ability that is needed is the ability to generalize one's experiences. In every-day terms it is the ability to use what one knows.
The work in applied mathematics should cover a wide range of problems worded in the language of the trades and constantly varied in order to establish as many points of contact as possible between the pupil's knowledge of mathematics and the use of mathematics in industrial life. Practical shop work is one of the best means to this end. The trouble with much of the shop work given in the schools is that it runs to hand craftmanship in which the object is to "make something" by methods long ago discarded in the industrial world, rather than to give the pupil exercise in the sort of thinking he will need to do after he goes to work. Successful teaching does not depend so much on the use of tools and materials as on the teacher's knowledge of the conditions surrounding industrial work and his ability to originate methods for vitalizing the instruction in its relation to industrial needs.
MECHANICAL DRAWING
At the present time the junior high school course provides for one hour a week of mechanical drawing. All the boys who may be expected to elect the industrial course can well afford to devote more time to drawing. For such boys no other subject in the curriculum, except perhaps applied mathematics, is of greater importance. In many of the trades the ability to work from drawings is indispensable and the man who does not possess it is not likely to rise above purely routine work.
In a drawing course for future industrial workers the emphasis should be placed on giving the pupil an understanding of the uses of drawing for industrial purposes, rather than on fine workmanship in making drawings. Seventh grade boys can't be made into draftsmen in three years and if they leave school at 15 they are not likely to become draftsmen. The ordinary skilled workman seldom has any need to make drawings or designs, beyond an occasional rough sketch, but he often has to work from drawings. To put it in another way, drawing to the average workman is like an additional language of which he needs a reading but not a writing knowledge. No doubt it would be well to teach him to write and read with equal skill, but in the two or three years most of these boys will remain in school there is not time enough to do both.
INDUSTRIAL SCIENCE
In many of the trades an introductory knowledge of physics and chemistry is of considerable advantage. Boys in the junior high school cannot be expected to take formal courses in these subjects, but they should not leave school without some acquaintance with them and a knowledge of their relations to industrial processes. A fair equipment should be provided for demonstrational and illustrative purposes. The subject matter should be correlated as closely as possible with the shop work, and the principal mechanical and chemical laws explained as the shop problems furnish examples of their application.
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.
