Though some business schools charge for the "case studies" they develop as teaching aids, the Massachusetts Institute of Technology announced today that it is making a set of teaching materials available free online. MIT's Sloan School of Management has unveiled a set of case studies, videos, interactive teaching tools, and teacher's notes on a new Web site called MIT Sloan Teaching Innovation Resources - https://mitsloan. mit.edu/MSTIR.

The announcement comes eight years after MIT created its OpenCourseWare project, which makes instructional materials for courses available online for free. What distinguishes the new site, according to JoAnne Yates, deputy dean for programs, is that whereas OpenCourseWare allows visitors to browse a linear series of resources and notes for a specific course, the management-school' s site allows them to search for specific "teaching artifacts"e. g., case studies or simulation modelsthat might be applied to any number of courses. Those artifacts will be searchable by concept or
business problem, like sustainability.
