เนื้อหาย่อ : Introduction Written instructional materials are recognized by instructors of industrial arts as an essential to effective teaching ; likewise as a means of dealing more effectively with individual differences and as a means of developing self-reliance, resourcefulness and capacity for self-direction. Information that is not necessary to the successful performance of a specific operation, but is necessary to a clear understanding and apprecia- tion of the subject is given throughout this book. It is this phase of indus- trial arts that has been most neglected and which will probably continue so, unless instructors in planning their work make provision or create situations which will require students to see the need of securing significant or necessary information before proceeding with construction. The success one has in getting students to master information and fulfill assignments will depend largely upon the efforts put forth and the attitudes assumed. One may be certain that, ordinarily, students will make little effort to acquaint themselves with items of information from a printed source that can be secured from the instructor, simply by asking. Neither will the average student greatly concern himself with mastery of information if he is reasonably certain that he will not be called upon to show knowledge of such. On the other hand, when students know they are going to be held to account for a given assignment, it is remarkable how well they meet the occasion. In the operation units all instructions necessary to perform the opera- tion correctly are given. The advantages of written operation units are: 1, they supply the student with a permanent source of information to which he can refer as he has need or oceasion ; 2, they enable the student to secure desired information independently; 3, they aid the student in de- veloping self-reliance and capacity for self-direction in that they make it possible for him to proceed on his own initiative; 4, students are not re- quired to wait until the instructor can find time to instruet them; 5, stu- dents taken to task for performing operations incorrectly cannot excuse their errors on the ground of not being able to secure information as to how the operation should have been performed. In preparing for a demonstration of a particular operation, the in- structor should orient himself with respect to the manner in which the operation is to be performed. In making the demonstration, the instructor
