Book excerpt: Excerpt from Electrical Construction: An Elementary Course for Vocational Schools A realization of the difficulties involved in obtaining drawings which show clearly the principles of electrical construction, has led to the preparation of the following les sons or problems. The author's experience as a teacher has shown conclusively that many hours of the teacher's limited time are expended uselessly in preparing such draw ings and blueprints. The primary aim, therefore, in placing this series of problems. With the accompanying drawings, before the public is to save the teachers, so far as possible, this needless labor of making such drawings and blueprints. This arrange ment of the material may further prove of value to the students for reference pur poses. Thruout, the problems are graduated in the order of difficulty they present, and, in most instances, each succeeding lesson or problem involves the outstanding features of those immediately preceding. Experience has shown that such sequential arrange ment is a positive aid toward understanding the principles involved. Teachers using this book will violate one of the most fundamental principles of teaching unless they consider these drawings merely as an effective means of revealing the principles involved and in no sense a standard to be set up and maintained before the class. The application of these must be left to the individual teachers and must necessarily vary in accordance with (1) commercial practices and (2) the individuali ties of the different students. There is slight probability that this arrangement, to gether with the fore-notes, could result other than satisfactorily in the hands of a wide awake teacher.
