Problem: The purpose of this study was to investigate the extent to which drafting machines were used in industry and in the instruction of drafting In the public high schools and to compare the extent of utilization in each. More specifically, the study sought to answer the following questions: (1) To what extent is the drafting machine used in Industry and the high school drafting classes? (2) What type of machine is most commonly used in each? (3) At which course level do students in high school drafting classes use drafting machines? (4) What instructional literature is being used to teach the use of the drafting machines, and to what extent is the chalkboard drafting machine used in the drafting departments? (5) What are the most prominent reasons for the industries and the high schools not having machines? (6) What are the opinions of industrial drafting supervisors on the importance of high school students using drafting machines? (7) What are the trends in both industry and the high schools toward the use of the drafting machine? Procedure: The data for this study were obtained by the use of the information form. Forms were sent to public high schools of the northern 23 counties of Illinois, and another form was sent to hard products industries of the same geographic area. These industries employed at least 500 people at that plant location. The responses were then tabulated and analyzed, and conclusions were drawn. Conclusions: Over 90 percent of the industries and almost two-thirds of the high schools have drafting machines. Nearly 90 percent of the drafting machines in use in both the industries and the high schools are the parallel arm type machines. Although there are not as many track type machines in use, the trend in the industries is toward the increased utilization of this type machine. There are a few high schools that permit students in all course levels to use the drafting machine. However, more schools allow the more advanced students to use the drafting machines and for a greater length of time. Some schools provide machines for all members of a given class. The most prominent reason for schools not having drafting machines is the lack of sufficient funds. The major reason a few industries do not have drafting machines is they prefer to use the parallel rule. By 1969, there will be 80 percent of these high schools that will have drafting machines. There still will not be enough machines in all schools to meet the students' needs according to the recommendation of the industries. The industries recommend that the drafting students should use the drafting machines at least one-half of the class time because of the trend toward increased usage of the drafting machines in industry and because of the present draftsmen not obtaining maximum efficiency in the use of the drafting machines. Most of the industries will furnish left-hand drafting machines, but very few of the high schools do. High schools use the manufacturers' manuals and teacher-prepared materials for aids in the instruction of the use of the drafting machine. The chalkboard drafting machine is used but not extensively in high school drafting classes.
