Excerpt from Experimental Electrical Engineering and Manual for Electrical Testing, Vol. 1: For Engineers and for Students in Engineering Laboratories The concentric method has marked advantages over the usual method with which the student is first given a thorough training in one subject, say direct-current machinery, before he is allowed to take up the next subject, for instance, alternating - current machinery. The principal advantage is that the concentric method is more in accordance with human nature; we always desire a bird's-eye View of a subject before we care to go into the details of a particular branch. In this way the course is made more interesting and more correct from a psychological point of View. Another advantage is that the student is brought in contact with the same subject at least three times during the course, and not only is he not allowed to forget it, but he sees it each time from a more advanced standpoint. There are also some minor advantages of the concentric arrangement. For instance, the student is better prepared for practical work during the summer between his Junior and Senior years if he has handled all classes of machinery in the Junior laboratory; he is prepared to read electrical periodicals; he can be given more delicate apparatus in the Senior laboratory, etc. The laboratory equipment may be utilized much better if various sections of students are allowed to work on entirely different subjects. However, as was mentioned above, the book may be used with any order in which the experiments might be performed in the laboratory. The plan followed in each chapter is this: first the particular class of machinery is described and the practical needs for certain arrange ments and procedures of operation are given; then the object and the method of each particular experiment are described in detail, and instructions given for the manner in which data should be taken. At the end of most experiments the requirements for the reports are stated so that the student will not omit to take all the necessary readings and dimensions while in the laboratory. It is advisable to have printed data sheets for the more complicated experiments; this will lead the student to take readings neatly and systematically and to record the general information about the appa ratus. In some cases diagrams of connections and the necessary pre cautions to be observed should be posted near the apparatus.
