headed "Operation," "Assignment," and "Time." Below the word "Operation" are set down the various operations undertaken in the woodworking department, with several vacant spaces provided where other and special operations can be filled in. It will also be noticed that "Operations" are divided into two kinds, machine work and bench work. The instructor's glance at the time card will tell him at once what phase of the work the boy has been employed in and will help him in apportioning the work so that the boy is offered a varied experience.
6. Using Time Card.—For shops that are not equipped with the kind of machines marked on the illustrated card, it would be well to omit the names of machines in the "operation" column. The instructor may then fill in the operation whatever it may be.
Under the heading "Assignment" and against the operation which is to be undertaken by the student, the instructor writes in the name of the part to be made. This is the student's assignment and it should be read by him at the time he records his presence at the time-card rack upon entering the shop.
In making assignments, the instructor may find it rather difficult to keep up with large classes of boys. This difficulty may be overcome by making an assignment to an entire group instead of to each boy. For example, in a class of twenty-five that would probably be divided into five groups, the instructor may make the assignment to the foreman of each group and each foreman in turn can inform the boys of his group as to the nature of the assignment. The boys can then enter the assignment on their time cards at the end of the period when the time spent on the job at hand is also recorded.
The student's shop number, name, and grade should be filled in by the time clerk who can get out a number of cards for each student in advance and these are kept ready for use by the instructor. The instructor can then mark the project and the job number together with the student's assignment. At the same time he estimates the journeyman's time and rate and enters them in the space provided.
The time card in Fig. 5, is 3½ inches by 9 inches, made of three-ply bristol board. All worker's cards are printed on white colored bristol while those of the foremen are of blue colored bristol. This plan is for the instructor's convenience to be able to pick out the foremen's time cards at a glance.
In the triple column under the heading "TIME" is provided room for the date and spaces in which the student can write the time in minutes spent on the various operations on that date. The triple columns on each side of the card allow of the cards being used for six days. If a job lasts longer than six days another card should be used marking them No. 1 and No. 2, respectively, in the space marked "Card No." Both cards should be fastened and kept together.
Effort should always be made to have all the assignments short (less than six days) so that the student's record may be computed at the end of each week by the time clerk.
7. Grading Students.—The next four spaces contain in condensed form, the information itemized in other parts of the card. This, together with other information set down by the instructor, is the vital material sought for.
The item A "Journeyman's Time" is very easily recorded by the instructor. It is arrived at in the same way as in making out the estimate for any piece of work and can be recorded almost at once. The main purpose here is to set for the student a standard of time on which to work.
The item B is the rate in points per hour, based on the journeyman's time.
The item C is the total of the student's time added together from the various spaces under "Time."
Item D "Quality Decimal" is the quality of the student's job expressed in the form of a decimal, with 100% as the maximum. This mark should be filled in by the instructor when the student completes his job.
The next item, the number of points the student earns is found by the formula Points = (A×B)D
Points earned per hour = | (A×B)D C |
For example, a student receives an assignment to cut to thickness, width, and length, sixty chair legs. The size of the legs he is to get from the job blueprint. He spends 60 minutes a day, for three days, making a total of 180 minutes or 3 hours. The time it would take a journeyman to do the same job is estimated at 2 hours. The rate adopted is at 80 points per hour; the journeyman therefore earns A×B = 2×80 = 160 Points. The quality of the student's job is graded by the instructor as 75%. The number of points the student earns is found by the formula Points = (A×B)D = (2×80).75 = 120 Points. To find the number of points the student earns per hour, divide 120 points by the number of hours it took the student to complete the job, which equals 120 ÷ 3 = 40, the number of points the student earns per hour. However, if the student would be graded 100%, he would earn the same number of points as the journeyman. But of course, he would have done it in three hours where the journeyman has earned the same number of points in two hours. It will readily be seen that this scheme offers the student an everlasting incentive to equal the journeyman's record.
Having obtained the points on the time card or assignment card as it may be called, these are then transferred to a monthly accomplishment sheet as shown in Fig. 6, which is provided for all the students in all classes.
The total number of points for each boy, group, and class can then be easily obtained. These totals can be put up in poster form and hung on the shop's bulletin board, showing the standing of each boy, group, and class. It is surprising the amount of interest and competition that can be aroused; everyone working for the highest honors, unconsciously, with a competitive spirit that will bring out considerable thought and effort to the matter of handling material for maximum production.
8. Preliminary Discussion and Preparation for Shopwork.—Of course, no time card or assignment-record scheme can hope entirely to eliminate the necessary preliminary discussions and preparation. The author has found it of material help to meet the foremen of all the classes at hours other than their regular class hour and discuss such topics as "Securing Cooperation," "Instructing Workers," "Maintaining Cleanliness and Order," "Records and Reports," "Inspecting Work," "Routing Material Thru Shop," "Care of Stock," etc.
Details regarding construction and assembling should be worked out by the instructor beforehand, and also developed with the class as the work progresses. Care should be taken that plans are carefully made regarding the storage of stock and unfinished parts.
The old saying, "An ounce of prevention is worth a pound of cure," is an old one, but a good one.
9. Bazaars, Toy Sales, Etc.—The plan of selling toys, that are made in the school shop, to the boys and girls of the school is a plausible one. It can very easily be accomplished in the form of bazaars, exhibitions, or school toy sales.
The writer has had a number of samples of different toys
