Book excerpt: Excerpt from Laboratory Manual of General Chemistry: With Exercises in the Preparation This laboratory manual has been written to meet the requirements of students of chemistry who already possess an elementary knowledge of the subject, such, for instance, as is acquired at our better high schools. How best to continue the chemical education of such students is one of the most difficult problems which confront teachers of chemistry in our colleges and universities. A time honored practice has been to ignore secondary school preparation entirely and give identical instruction to these men and to real beginners indiscriminately. This was doubtless justifiable some years ago when chemical instruction was new in our secondary schools and was, naturally, poor; but today it can only be defended on the ground of necessity. The larger institutions recognize this where the number of elementary students is adequate, and either have arranged separate laboratory sections for the differently prepared students, or, better still, give them wholly separate instruction. But even when segregation of this kind has been secured, the problem is by no means solved. Those students who have studied chemistry in the secondary school have already done a large share of the simple, important, and impressive experiments. The first freshness of their, interest in, and wonder at, chemical phenomena has been lost. On the other hand, to trust that the average college student retains any clear conceptions regarding the abstract matter of his secondary school chemistry, which is so important as a basis for further study, is to court disappointment. Besides, as every experienced college teacher knows, the very familiarity of such students with parts of the subject frequently leads to over-confidence about the whole of it - with disastrous results. Flagging interest then, hazy ideas about the principles of chemistry, and over-confidence are the special difficulties of the problem. The requirements then to be met by a laboratory manual of this kind are by no means easy. The most essential are, first, that those important facts and principles which the student has already studied shall be reviewed in a way sufficiently novel not to bore him, nor to encourage him to over-confidence; second, that the student's chemical horizon shall be widened by the study of new and unfamiliar substances; and third, that further important generalizations upon which the superstructure of the science is based, shall be disclosed and made clear. To meet these requirements I have resorted to several expedients. For instance, to review the weight relationships of chemical reactions, I have devised a series of simple, quantitative experiments quite different from the ones usually performed in a strictly elementary course.
