| Welcome to the Classroom Case Studies page. Each case study below is an Excel 97/98-5.0/95 spreadhseet file than can be downloaded automatically to your computer with either Microsoft Office 2007, 2004, or 98 (for Macintosh computers) or at least Windows 3.1 (for PC's). Each module contains a sample exercise, an automatic solution tableau, and a reset control panel. Course syllabi, which can be downloaded as Microsoft Word documents, contain automatic links to these case studies and related modules found elsewhere in this website. These tools should make learning as smooth as pouring milk from a pitcher.
