Architectural patterns in pedagogical agents

One possible way to start from a firm and stable engineering backbone when developing the architecture of an Intelligent Tutoring System (ITS) is to use patterns for ITS architectures. Speaking architecturally, a pattern is a generalized solution of a typical problem within a typical context. Knowledge of patterns and using them definitely brings more engineering flavor to the field of ITS. It is also important to stress that it does not mean abandoning learning theories, teaching expertise, curriculum structuring, or instruction delivery as the cornerstones of any intelligent tutor. Using patterns is just taking more care about AIED systems themselves, especially about the way we develop them. This paper presents new results of our continuous efforts to analyze well-known ITS architectures from the patterns perspective.
