The philosophical basis for the modules is that it is more beneficial for students to investigate a few topics in detail than to be presented with a cursory survey of many topics. Short chapter appendices can be added to the chapters of the core. Modules can be inserted between chapters or at the completion of the core. In addition to providing the instructor with a sequence of material that meets the needs of a particular group of students, this arrangement also makes it easy to add material prepared by the instructor. Please note that this preliminary edition of the text consists of two volumes.
Volume one contains the core and the chapter appendices.
Volume two contains the modules. This structure allows the instructor to select the core and only a few chapter appendices and modules, and not to attempt to cover all chapter appendices and modules. The first edition of the text will have a format that will allow instructors to order a text containing only the core plus the chapter appendices and modules selected by the instructor. The text is written for the introductory chemistry course for science and math majors. Its flexibility, however, makes it adaptable to most introductory chemistry courses.
