Nakajima University, Hatoyama-cho, S ait am a- ken 350-03, Japan ABSTRACT The INTELLITUTOR was designed as an integrated environment for both learning programming and friendly programming aid. The system consists of three software modules, i.e., GUIDE, ALPUS and TUTOR, one document database and four knowledge bases. GUIDE is a guided editor for easy coding, ALPUS is a knowledge-based program understander, and TUTOR is an embedded intelligent tutoring system. ALPUS infers user's intentions from buggy program codes by means of knowledge-based reasoning. INTELLITUTOR attempts to work as a human programming tutor to guide a user in programming, to detect logical errors within a user' program, and to make advices not only for fixing them but also for letting him notice his misunderstandings. The key knowledge used to understand user's programs is the knowledge about algorithms, which is organize
