Publisher's Synopsis
Excerpt from Introduction to Physical Science
An experience of about six years in requiring individual laboratory work from my pupils has constantly tended to strengthen my conviction that in this way alone can a pupil become a master of the subjects taught. During this time I have had the satisfaction of learning of the successful adoption of laboratory practice in all parts of the United States and the Canadas; likewise its adoption by some of the leading universities as a requirement for admission. Meantime my views with reference to the trend which should be given to laboratory work have undergone some modifications. The tendency has been to some extent from qualitative to quantitative work. With a text-book prepared on the inductive plan, and with class-room instruction harmonizing with it, the pupil will scarcely fail to catch the spirit and methods of the investigator, while much of his limited time may profitably be expended in applying the principles thus acquired in making physical measurements.
A brief statement of my method of conducting laboratory exercises may be of service to some, until their own experience has taught them better ways. As a rule, the principles and laws are discussed in the class-room in preparation for subsequent work in the laboratory. The pupil then enters the laboratory without a text-book, receives his note-book from the teacher, goes at once to any unoccupied (numbered) desk containing apparatus, reads on a mural blackboard the questions to be answered, the directions for the work to be done with the apparatus, measurements to be made, etc.
