Case-based reasoning systems are increasingly being used in education settings. The Knowledge Innovation for Technology in Education (KITE) system is a pioneering attempt to develop a CBR case library in the educational technology integration community. The KITE system seeks to assist teachers by providing access to a case library with over 1200 stories of teachers’ experiences with technology. The project was supported from 2001-2004 by a grant from the U.S. Department of Education. The URL is http://kite.missouri.edu/.
There are several challenges to reusing cases from the KITE case library or any other knowledge repositories. Similar to many Web-based case repositories, the KITE system suffers from lack of user participation and therefore lack of growth, due to ineffective support for exploring, creating and evolving the cases. Some common issues include:
1) Sustainability. The cases in the repository become out-of-date as new technologies are developed. A case library must keep growing by integrating new cases into the case-base in order to keep users' interest and meet the needs of users as time goes by.
2) Case quality. A case in a repository may not adequately describe all aspects of a situation, or the information in a case may not be of value to users. It is necessary to get feedback from a community of users in order to improve the content quality of cases and avoid mistakes.
3) Case Adaptation (Reuse/Revision). Oftentimes, case adaptation is a very complicated process and requires considerable user expertise (Leake, Kinley, & Wilson, 1995). The KITE case library relies on users to adapt the solutions they find in the case library to fit the technology integration problems they face. In the KITE system, there are no mechanisms devised to help users with solution adaptation based on their own circumstances. It is important to explore the heuristics that can be used to guide users in adapting technology integration solutions effectively and efficiently.
