This paper describes a suite of flexible software tools (CoMMIT-Collaborative Multi-Media Instructional Toolkit) that provides computer support for a variety of educational models including cooperative, distance, and problem-based learning. Students using CoMMIT have worked both synchronously and asynchronously in a variety of domains. The CoMMIT system provides a comprehensive, collaborative learning environment that includes integrated modules for authoring, student learning and student evaluation. This paper briefly introduces each of the three CoMMIT modules and focuses on the WWW-based student module using a problem-based learning (PBL) case to illustrate its functionality. The CoMMIT student module was recently used and evaluated against a paper-based PBL case that required students to collaborate on the design of an information system. An evaluation of the results is given.
