A Text Book On The Elements Of Physics For High Schools And Academies

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from A Text-Book on the Elements of Physics for High Schools and Academies Every teacher has a method of his own. But perhaps the follow ing plan, practised by the author, may be suggestive to some: He divides the experiments into three classes: home, laboratory, and lecture-room experiments. The first class are indicated in the assign ment of a lesson. They are such as may be performed with such simple means as every pupil has at his home. The laboratory experi ments are conducted as follows: Suppose that the number of pupils engaged at one time is fifteen, about as many as one teacher can care for successfully, and that the number of experiments to be performed during the hour is five, which is about an average number; then, to save a multiplicity of apparatus of the same kind, only three sets of apparatus of a kind are provided for each experiment. As soon as a pupil completes an experiment with one piece of apparatus, he looks about for an idle piece of some other kind; or, finding none, he improves the time in writing notes on his experiments until apparatus is ready for him; in this way each pupil performs five experiments during the hour, and devotes an average time of twelve minutes to each experiment, including the time of writing notes. The third class of experiments include such as require the use of apparatus that cannot safely be placed in the hands of pupils, - a very limited number, and those which have been performed by the pupils, and which the teacher may wish to repeat in a more elaborate way.
