Excerpt from Senior Chemistry
According to modem standards a good secondary education should include a general acquaintance with the elements of science, and in addition a fairly detailed study of at least one branch. Without this deeper knowledge of one branch the educational value of the science course is seriously diminished. It is the object of this book to provide such a course of more detailed study in chemistry and to deal with those portions of the subject that are commonly required in schools.
It is now generally conceded that for work of this standard a judicious combination of the heuristic and didactic methods of teaching should be used. The elements of systematic chemistry are required, and if these are taught by the purely heuristic method, progress is needlessly slow, and the knowledge obtained, is needlessly scrappy and incomplete. At the same tune the treatment must still be experimental, for personal contact with the phenomena under discussion is still necessary if the student is to appreciate fully the points at issue. These are the main principles in accordance with which this volume has been prepared.
The book is divided into four Sections. Section I: is an Introductory Course of the approved type, based on a series of experiments by which the fundamental principles of the science are established in their proper sequence.
