A Laboratory Course in Physics for Secondary Schools (Classic Reprint) - Tapa blanda

Excerpt from A Laboratory Course in Physics for Secondary Schools

Since the precise method of accomplishing this end will depend upon the sort of laboratory equip ment which is available, the course has been given considerable flexibility by introducing alternative experiments.

Thus, if gas is not accessible the student will omit Exp. 5, but will get exactly the same principle through performing Exp. 5a. Or, if the laboratory is not equipped with commercial ammeters and voltmeters, Exp. 31 will be omitted and Exp. 31 A performed. Similar choices will be found indicated throughout the text.

Another feature of the course is that the experiments do not presuppose any previous study of the subject involved, or any antecedent knowledge of physics. The laboratory work may be kept in advance of the classroom discussion throughout the entire course if desired. Indeed, in their own elementary work the authors prefer to let more than half of the experiments constitute the student's first introduction to the subject treated. Furthermore, students are neither instructed nor advised to study their experiments before entering the laboratory, for each experiment has been arranged to carry with it its own introduction.

Excerpt from A Laboratory Course in Physics for Secondary Schools

Although laboratory work is now generally recognized as an indispensable part of any adequate course in elementary physics, it is nevertheless a lamentable fact that there are still some schools in which it is not attempted at all, while there are others in which, despite the most expensive equipment, the laboratory fails, on the whole, either to interest or instruct.

Both of these conditions are probably attributable to one and the same cause. In our modern glorification of the laboratory method, particularly of exact, quantitative measurements, and in our haste to get away from the superficial, descriptive physics of thirty years ago, some of us have undoubtedly gone so far as to defeat our own aims. We have made the laboratory an impossibility in schools which are financially weak, because we have made its expense prohibitive; and we have made it a disappointment in other schools which are financially strong, because in our eagerness to show our students exactly how much we have neglected to show them how and why. In short, the gravest danger which threatens the efficiency of the high-school laboratory to-day is the danger which arises from the creeping over of the methods and the instruments of research and specialization from the university into the high school, where they have absolutely no place, - the danger that principles shall be lost sight of in the bewildering details of refined methods and refined instruments.
