This paper describes a new approach to asynchronous distance education, namely the employment of Case Based Reasoning (CBR) as part of the teaching procedure of a domain independent educational environment called See Yourself Improve (SYIM_ver2). SYIM was initially implemented at Athabasca University – Canada’s Open University and the University of Macedonia in Greece. SYIM’s goal is to provide students personalized distance education services via asynchronous distance education sessions, a goal which has also contributed to the construction of new student models.
