Why Modules? We listened to the increasing demand of instructors for more flexibility with teaching materials. Sociology in Modules provides an appealing alternative for those instructors who feel that breaking up each chapter into 2-4 modules would allow them to assign the content they want in the order that they want. This modular format was also created to cater to the way in which students learn. Using an adaptive diagnostic tool to help students identify what they know and don't know, Sociology in Modules helps students move towards an understanding of the foundations of sociology by presenting material in more manageable chunks. Rather than facing a long and potentially daunting chapter, modules break up material and help students study information in shorter intervals. Richard T. Schaefer has adapted his proven content to fit this modular format. As an experienced author of sociology, his willingness to meet the changing needs of instructors and students makes Sociology in Modules the most flexible program for teaching sociology.
