Explanations are essential in the teaching process. Tracers are one possibility to provide students with explanations in an intelligent tutoring system. Their development can be divided into four steps: the definition of the trace model, the extraction of the information from this model, the analysis and abstraction of the extracted information and the visualization of the result of the analy-sis. This article describes the architecture of a domain independent tracer developed in Visual Prolog displaying explanations in the form of a textual dialog or a graphical tree.
